Cal. Code Regs. tit. 17 § 93118.5

Current through Register 2024 Notice Reg. No. 44, November 1, 2024
Section 93118.5 - Airborne Toxic Control Measure for Commercial Harbor Craft
(a)Purpose and Intent.

The purpose and intent of this section is to reduce diesel particulate matter (PM), oxides of sulfur (SOx), oxides of nitrogen (NOx), and greenhouse gas (GHG) emissions from diesel propulsion and auxiliary engines on harbor craft that operate in any of the waters subject to this section ("Regulated California Waters"). This section implements provisions of the Goods Movement Emission Reduction Plan, adopted by the California Air Resources Board (ARB or CARB) in April 2006, to reduce emissions and health risk from ports and the movement of goods in California. This Control Measure also ensures that commercial harbor craft do not create excess visible emissions. California's commercial harbor craft operations are largely situated in the vicinity of at-risk communities that directly benefit from localized reductions of NOx and PM emissions. This contributes to meeting community health goals as set forth in Assembly Bill 617 (Garcia, Stats. 2017, ch. 136). Furthermore, NOx and PM emission reductions contribute to meeting California's State Implementation Plan obligations for attainment, and further CARB's obligations under sections 39660 et seq. and 43013 et seq. of the Health & Safety Code. Additionally, use of shore power has a benefit of simultaneously reducing toxic, criteria pollutant, and GHG emissions. This contributes to meeting California's GHG emission reduction targets established in Assembly Bill 32 (Nunez, Stats. 2006, ch. 488) and Senate Bill 32 (Pavley, Stats. 2016, ch. 249).

Beginning January 1, 2009, a person subject to this section may only fuel a diesel engine on a harbor craft with one of the following:

(A) CARB diesel fuel; or
(B) an alternative diesel fuel as defined in subsection (d)(2); or
(C) any alternative diesel fuel that does not meet subsection (e)(1)(B) above but is certified by CARB as meeting the requirements of the Verification Procedure; or
(D) CARB diesel fuel used with fuel additives that meet the requirements of the Verification Procedure; or
(E) any combination of subsection (e)(1)(A) through (D) above; or
(F) if a harbor craft subject to this section is traveling from a port located outside of California, and that port does not have any fuels listed in subsections (e)(1)(A) through (E), that vessel's diesel engines can be fueled with either: U.S. EPA on-road diesel fuel meeting the specifications contained in 40 CFR §§ 80.500 et seq., as they existed on April 27, 2010, or U.S. EPA nonroad diesel fuel meeting the specifications contained in 40 CFR § 80.29 as it existed on April 27, 2010, and 69 FR 38958 (June 29, 2004). The vessel owner or operator must retain records documenting the fuel purchase, the location and the name of the non-California port, and its lack of availability of fuels listed in subsections (e)(1)(A) through (E) on-board the vessel for a minimum of one year after the purchase of the fuel, and must make such records available upon the request of the Executive Officer.
(2)All Harbor Craft -- Installation and Use of Non-Resettable Hour Meters.

Beginning January 1, 2009, a person subject to this section may not operate a harbor craft without an installed and properly operating, non-resettable hour meter, which accurately measures the number of hours an engine operates. The hour meter must be installed on each diesel engine on the vessel in a manner that allows reasonable personnel access to the hour meter without impediment. Beginning January 1, 2023, if an hour meter fails to properly operate in accordance with manufacturer specifications, a person subject to this section must, within 30 days, replace the hour meter that is failing to operate properly and report to CARB the date the hour meter stopped operating properly, the date the hour meter was replaced, and the hour readings of both the hour meter that failed to operate properly and the replacement hour meter as of the date of replacement. Beginning January 1, 2023, if an existing hour meter is replaced, a person subject to this section must, within 30 days, report to CARB the date the existing hour meter was replaced, and the hour readings of both the existing hour meter that was replaced and of the replacement hour meter as of the date of replacement.

(3)All In-Use Harbor Craft -- Requirements for Newly Acquired Engines (Applicable Until December 31, 2022).

During the time period beginning January 1, 2009 and ending December 31, 2022, a person subject to this section may not sell, purchase, offer for sale, lease, rent, import, or otherwise acquire a new or in-use diesel engine for an in-use harbor craft, which is intended to operate or actually operates in any of the Regulated California Waters, unless that engine on the date of acquisition:

(A) is certified to meet the Tier 2 or Tier 3 marine standards in effect on that date for a new engine of the same power rating and displacement. The newly acquired engine is not required to meet the Tier 4 marine standards unless it is replacing an engine on the in-use vessel that was certified as meeting Tier 4 marine standards. Engines certified to meet the Tier 2, Tier 3, or interim Tier 4 off-road standards in effect on the date of acquisition for a new engine of the same power rating and displacement may only be acquired for use as an auxiliary or propulsion engine on harbor craft if the engine or vessel manufacturer has complied with 40 CFR § 1042.605 (Marinized land-based engines already certified to other standards for nonroad or heavy-duty highway engines for marine use), as it existed on April 27, 2010; or
(B) is newly acquired within the allowable 6 month "sell-through" period, as set forth in this paragraph. For purposes of this paragraph only, the allowable sell-through period runs through 6 months after the date the Tier 2, Tier 3, or Tier 4 marine standards or Tier 3, interim Tier 4, or final Tier 4 off-road standards have come into effect for a new engine of the same power rating and displacement as the engine being replaced on the in-use vessel. Engines that are subsequently sold, supplied, offered for sale, or otherwise newly acquired after the 6 month sell-through period are subject to the requirements specified in paragraph (A) of this subsection, even if the engine was previously newly acquired within the 6 month sell-through period; or
(C) is replacing an engine that is non-functioning due to equipment failure, and the E.O. has determined, pursuant to the provisions of 40 CFR § 1042.615 engine replacement exemption, as it existed on April 27, 2010, that no engine certified to the current standards is produced by any manufacturer with the appropriate physical or performance characteristics to repower the vessel. In such event, an alternate engine may be acquired for the replacement. Pursuant to 40 CFR § 1042.615, a separate determination, addressing each tier of emission standards that is more stringent than the emission standards for the engine being replaced must be made. For example, if the engine being replaced was built before the Tier 2 standards applied, and engines of that size are currently subject to Tier 3 standards, a person must consider whether any Tier 2 or Tier 3 engines have the appropriate physical and performance characteristics for replacing the old engine. If a Tier 2 engine is determined to have the appropriate physical and performance characteristics, it may be selected as the replacement engine. Documentation of these determinations must be supplied to the E.O. and the E.O.'s determination must be obtained before an engine replacement is made pursuant to this provision.
(4)All New Harbor Craft (Including All New Ferries) -- Requirements for Newly Acquired Vessels (Applicable Until December 31, 2022).

During the time period beginning January 1, 2009 and ending December 31, 2022, a person subject to this section may not sell, purchase, offer for sale, lease, rent, import, or otherwise acquire a new harbor craft for use in any of the Regulated California Waters unless each diesel propulsion and auxiliary engine on the vessel meets the applicable Tier 2, Tier 3, or Tier 4 marine standards in effect on the date of vessel acquisition. Auxiliary or propulsion engines meeting the applicable Tier 2, Tier 3, interim Tier 4, or final Tier 4 off-road standards in effect on the date of vessel acquisition may be sold, purchased, offered for sale, leased, rented, imported, or otherwise acquired for use if the engine or vessel manufacturer has complied with 40 CFR § 1042.605 (Marinized land-based engines already certified to other standards for nonroad or heavy-duty highway engines for marine use), as it existed on April 27, 2010. Diesel propulsion engines in new ferries with a capacity to transport more than 75 passengers in Regulated California Waters must also meet the requirements specified in subsection (e)(5) below.

(5)Selected New Ferries Only -- Additional Requirements for All Newly Acquired Propulsion Engines (Applicable Until December 31, 2022).
(A) During the time period beginning January 1, 2009 and ending December 31, 2022, any person who owns or operates a new ferry with the capacity to transport 75 or more passengers and that is used in any of the Regulated California Waters must demonstrate that each diesel propulsion engine that is certified to either the Tier 2 or Tier 3 marine standards will be operated in conjunction with the use of Best Available Control Technology (BACT) as determined and pre-approved by the E.O. pursuant to this provision.
(B) For purposes of this section, "BACT" is the diesel emission control strategy (DECS), whether verified or unverified pursuant to 13 CCR section 2700 et seq., that is determined by the E.O. as meeting all of the following criteria:
1. it provides or is expected to continuously provide the greatest reduction feasible of NOx or diesel PM when used with the ferry's propulsion diesel engine;
2. the use of BACT does not result in an increase of 10 percent or more of any air pollutant, including NOx and diesel PM, relative to the engine's emissions of that air pollutant without the use of BACT; and
3. either the DECS manufacturer or an authorized dealer of the DECS determines or otherwise agrees with the E.O. that use of the DECS on or with the new ferry's propulsion engine(s) would not invalidate or otherwise adversely affect the propulsion engine's original warranty.

For purposes of this section, DECS may include, but is not limited to, exhaust treatment controls and the use of alternative fuels or fuel additives.

(C) The E.O. shall determine the appropriate level of BACT and specify such BACT in an Executive Order granting such approval. Applications to comply with the requirements of paragraph (A)2 by using BACT must follow the application and review procedure set forth below:
1. Application Process.

For all new ferries for which the keel is laid on or after January 1, 2009, the application for BACT approval must be submitted in writing to the E.O. for evaluation before the keel is laid. The BACT application must contain, at a minimum, the following information:

a. the applicant company's name, address, and contact information;
b. information specific to the harbor craft and engine(s) on which BACT will be used, including the vessel name and identification number(s); engine make, model, and serial numbers; and all other information that uniquely identify the engine;
c. certification documentation, engineering calculations, emissions test data, or other information that establishes the diesel PM and NOx emissions of the engine in combination with the proposed BACT. Emissions and emission reduction estimates must include both diesel PM and NOx emissions and be expressed in grams per brake horsepower-hour (g/bhp-hr) unless otherwise specified by the E.O. Information submitted pursuant to this provision will be used as follows:
i. The E.O. shall use the information to compare the emissions resulting from the proposed use of BACT with the emissions quantified in BACT determinations previously approved by the E.O.;
ii. If there are no previous BACT determinations available for comparison, the E.O. shall use CARB staff's best engineering judgment to determine if the proposed BACT provides the greatest feasible reduction of diesel PM or NOx; and
iii. The E.O. may require the applicant to submit additional emissions data for other air pollutants if the E.O. believes that the proposed use of BACT may increase any air pollutant by 10 percent or more relative to the engine emissions without the proposed BACT; and
d. the proposed recordkeeping, reporting, monitoring, and testing procedures that the applicant plans to use to demonstrate continued effectiveness of the BACT.
2. E.O. Review and Final Decision-Making Process.
a. Within 15 days after receiving a BACT application, the E.O. shall notify the applicant whether the application is deemed sufficiently complete to proceed with further evaluation. If the application is deemed incomplete, the notification must identify the application's deficiencies. The E.O. shall have an additional 15-day period for reviewing each set of documents or information submitted in response to an incomplete determination. Nothing in this subsection prohibits the E.O. from requesting additional information from the applicant, during any part of the BACT application process, which the E.O. determines is necessary to evaluate the application.
b. Within 30 days of deeming an application complete, the E.O. shall take final action to either approve or deny a BACT application, and the E.O. shall notify the applicant accordingly. If the application is denied or modified, the E.O. shall state the reasons for the denial or modification in the notification. The E.O. shall specify all terms, conditions, and requirements the E.O. believes are necessary for the ferry engine and BACT to operate properly and reduce emissions of air pollutants consistent with this section. The reporting and recordkeeping requirements specific to the use of BACT must include, at a minimum:
i. hours of operation for the engine and BACT and fuel usage;
ii. usage of any alternative fuels, additives, agents, flow rates, and emission test results;
iii. maintenance procedures for the engine(s) and its BACT; and
iv. any other measurements or recordings specified by the E.O.

The E.O. shall make the approval/disapproval notification to the applicant and identification of the approved/disapproved BACT available to the public on CARB's internet site.

3. Post-Approval Vessel, Engine, and BACT Operation.

A person who owns or operates a new ferry with the capacity to transport 75 or more passengers and that is used in Regulated California Waters must maintain operating records and other information in the manner and form specified by the E.O. in the BACT approval and must submit to CARB upon request all records and reports created pursuant to this provision, which must be maintained and retained for CARB inspection a minimum of three years after the records or reports were created.

(6)In-Use Engines and Vessels -- Schedules for Meeting Tier 2 or Tier 3 Standards (Applicable Until December 31, 2022).
(A)For Pre-Tier 1- and Tier-1 Certified Engines on Ferries, Excursion Vessels, Tugboats, Towboats, Push Boats, Crew and Supply Vessels, and Barge and Dredge Vessels Only.
1.Applicability.

This subsection (e)(6) applies, until December 31, 2022, to any person who owns, operates, sells, purchases, offers for sale, leases, rents, imports, or otherwise acquires an in-use ferry, excursion vessel, tugboat, towboat, push boat, crew and supply vessel, or barge and dredge vessel (in-use regulated category vessel) with a pre-Tier 1- or Tier 1-certified marine or off-road engine operating in any one of the above regulated in-use vessel categories for:

a. a total of 300 hours per calendar year or more if operating in either ferry, excursion vessel, tugboat, towboat, push boat, or crew and supply vessel categories, or
b. a total of 80 hours per calendar year if operating in either barge or dredge vessel categories in Regulated California Waters. This subsection applies to all such engines on all such vessels.
2.General Requirement.
a. During the time period beginning January 2, 2009 and ending December 31, 2022, a person who owns, operates, sells, purchases, offers for sale, leases, rents, imports, or otherwise acquires an in-use ferry, excursion vessel, tugboat, towboat, or push boat with a pre-Tier 1- or Tier 1-certified marine or off-road engine and that operates in any of the above regulated in-use vessel categories may not own, operate, sell, purchase, offer for sale, lease, rent, import, or otherwise acquire an in-use engine, or a vessel with an in-use engine, unless that engine complies with at least one of the compliance methods set forth in subsection (e)(6)(C) by the applicable compliance date. The compliance methods set forth in subsection (e)(6)(C) involve either replacement of the in-use engine with a cleaner engine or demonstrating that the in-use engine already meets specified standards, as set forth below.
b. During the time period beginning July 1, 2011 and ending December 31, 2022, a person who owns, operates, sells, purchases, offers for sale, leases, rents, imports, or otherwise acquires an in-use crew and supply vessel, or barge and dredge vessel with a pre-Tier 1- or Tier 1-certified marine or off-road engine and that operates in any of the above regulated in-use vessel categories may not own, operate, sell, purchase, offer for sale, lease, rent, import, or otherwise acquire an in-use engine, or a vessel with an in-use engine, unless that engine complies with at least one of the compliance methods set forth in subsection (e)(6)(C) by the applicable compliance date. The compliance methods set forth in subsection (e)(6)(C) involve either replacement of the in-use engine with a cleaner engine or demonstrating that the in-use engine already meets specified standards, as set forth below.

For purposes of this subsection, "applicable compliance date" is either the compliance date, as set forth in subsection (e)(6)(D) for the in-use engine, or the compliance date from subsection (e)(6)(D) for the in-use engine, as extended pursuant to subsection (e)(6)(E), whichever applies and occurs later.

(B) [Reserved for Future Use]
(C)Compliance Methods.
1.Method C1 -- Replacement of the in-use engine with a U.S. EPA certified marine or off-road Tier 2 engine or one with a higher certification level (e.g., Tier 3-certified).

A person may comply under this method by replacing the in-use engine with an engine certified to Tier 2 or Tier 3 marine or off-road engine emission standards as set forth in this paragraph. The replacement engine must meet the U.S. EPA Tier 2 or Tier 3 marine or off-road engine emission standards that would apply to a new engine, of the same size and configuration as the in-use engine, at the time of the applicable compliance date set forth in subsection (e)(6)(D). The replacement engine must meet the provisions of section 93118.5(e)(3).

[NOTE: For example, if the applicable compliance date is January 1, 2010, and the Tier 2 marine or off-road emission standards would be in effect at that time for a new engine of the same size and configuration as the in-use engine, the replacement would need to meet Tier 2 marine or off-road emission standards. However, if the applicable compliance date is instead January 1, 2013, and the Tier 3 marine or off-road emission standards would be in effect for a new engine of the same size and configuration as the in-use engine, the replacement engine would need to meet Tier 3 marine or off-road emission standards.]

Once the in-use engine has been replaced with an engine that is U.S. EPA-certified to meet Tier 2 or Tier 3 marine or off-road emission standards, as set forth above, the engine is deemed to be in compliance with this subsection (e)(6) and no further replacements of this engine are required under this subsection. Tier 3-certified marine or off-road engines may be used as the replacement engine to comply with this paragraph, even if Tier 4-certified marine or off-road emission engines become available by the applicable compliance date;

2.Method C2 -- Demonstrate to the E.O.'s written satisfaction that the in-use engine already meets the Tier 2 marine standards or Tier 2 off-road standards for auxiliary or propulsion engines greater than 50 hp or less than 75 hp, or greater than 750 hp that apply or would apply to new engines on the date the Tier 2 marine or off-road standards became effective.
a. A person may comply under this method by demonstrating to the E.O.'s written satisfaction that:
i. the in-use engine already meets the Tier 2 marine standards or Tier 2 off-road standards for engines greater than 50 hp or less than 75 hp, or greater than 750 hp,
ii. which apply to new engines of the same power rating and displacement as the in-use engine.
b. This compliance method is available only if the person makes the required demonstration before the date Tier 3 marine or off-road emission standards become effective for new engines of the same size and configuration as the in-use engine. The person may rebuild the in-use engine to a cleaner standard or implement a diesel emission control strategy to aid in meeting these standards. [Note: For example, if the Tier 3 marine or off-road emission standards would have become effective on January 1, 2015 for a new engine of the same size and configuration as the in-use engine, the person would need to provide the Tier 2-compliance demonstration to the E.O.'s written satisfaction by January 1, 2015.]
c. For purposes of the demonstration, the person may, upon approval by the E.O., rely on any source of reliable and credible information. The E.O. will base their determination on the following information:
i. the results from using the test method specified in subsection (q) or an alternative method approved by the E.O.;
ii. the in-use engine manufacturer's certification test data or other emissions test data for that in-use engine;
iii. emissions test data derived from another in-use engine that is configured and used in a substantially similar way to the in-use engine;
iv. emissions test data used to meet the regulatory requirements of ARB's Verification Procedure for the non-verified emission control strategy implemented; or
v. emissions test data used to meet the requirements for U.S. EPA certification for systems providing remanufacture to a cleaner standard.

The E.O. may, in his/her sole discretion and based on good engineering judgment, exclude any information he/she determines is not reliable or credible.

3.Method C3 -- Demonstrate to the E.O.'s written satisfaction that the in-use engine already meets the Tier 2 or Tier 3 marine or Tier 2 or Tier 3 off-road emission standards for auxiliary or propulsion engines in effect or would be in effect for new engines at the time of the applicable compliance date.
a. A person may comply under this method by demonstrating to the E.O.'s written satisfaction that:
i. the in-use engine already meets the Tier 2 or Tier 3 marine or Tier 2 or Tier 3 off-road emission standards for auxiliary or propulsion engines,
ii. which apply to new engines of the same power rating and displacement as the in-use engine,
iii. at the time of the applicable compliance date for the in-use engine.
b. To comply with this method, the person may demonstrate that the in-use engine meets the Tier 3 marine or off-road engine emission standards, even if Tier 4 marine or off-road engine emission standards come into effect by the applicable compliance date. The person may rebuild the in-use engine to a cleaner standard or implement a diesel emission control strategy to aid in meeting these standards.
c. For purposes of the demonstration, the person may, upon E.O. approval, rely on any source of reliable and credible information. The E.O. will base their determination on the following information:
i. the results from using the test method specified in subsection (q) or an alternative method approved by the E.O.;
ii. the in-use engine manufacturer's certification test data or other emissions test data for that in-use engine;
iii. emissions test data derived from another in-use engine that is configured and used in a substantially similar way to the in-use engine;
iv. emissions test data used to meet the regulatory requirements of ARB's Verification Procedure for the non-verified emission control strategy implemented; or
v. emissions test data used to meet the requirements for U.S. EPA certification for systems providing remanufacture to a cleaner standard.

The E.O. may, in his/her sole discretion and based on good engineering judgment, exclude any information he/she determines is not reliable or credible.

4.Method C4 -- Demonstrate to the E.O's written satisfaction that the in-use engine has not and will not operate 300 or more hours per calendar year in any of the regulated in-use vessel categories or 80 or more hours per calendar year in the barge or dredge vessel categories.

A person may comply under this method by demonstrating to the E.O.'s written satisfaction that the engine is a low-use engine. This compliance method requires the person to provide records to the E.O. of the engine's total annual hours of operation while operating in any of the regulated in-use vessel categories for the calendar year immediately preceding the demonstration. The person must also provide documentation sufficient for the E.O. to project future annual hours of operation for the engine. The person will be deemed in compliance with this method only if such records and documentation demonstrate to the E.O.'s written satisfaction that the in-use engine has not and will not operate 300 or more hours per calendar year in any of the regulated in-use vessel categories with the exception of the dredge or barge categories, or 80 or more hours per calendar year in either the dredge or barge categories.

(D)Compliance Dates.

Table 7, Table 8, Table 9, and Table 10 below set forth the compliance dates by which a person must meet the requirements of subsection (e)(6)(A). Table 7 applies only to engines on ferries, excursion vessels, tugboats, towboats, and push boats with a homeport outside of the SCAQMD; Table 8 applies only to engines on ferries, excursion vessels, tugboats, towboats, and push boats with a homeport within the SCAQMD; Table 9 applies only to engines on crew and supply vessels; and Table 10 applies only to engines on barge and dredge vessels. The compliance dates are set forth by engine model year and total annual hours of operation (for use in any regulated in-use vessel category) of the vessel in Regulated California Waters. For Table 7, Table 9, and Table 10, Method D1, D2, or D3 below may be used for determining the actual or effective engine model year. For Table 8, only Method D1 or D3 may be used for determining the actual or effective engine model year.

1.Method D1 -- the engine's actual model year of manufacture.

A person may determine an engine's compliance date under this method by using the engine's actual model year of manufacture, as documented by the sales contract, invoice, purchase order, or other legitimate proof of purchase for the engine. The actual model year of manufacture may also be shown on a label permanently affixed to the engine by the manufacturer. In the event of a conflict between the proof of purchase and the permanent label, the date of manufacture shown on the permanent label controls.

2.Method D2 -- the engine's effective model year based on the "Engine's Model Year + 5" method.

A person may determine an engine's compliance date under this method by calculating the engine's effective model year as the actual model year, using Method D1 above, and adding to that number 5 more years. To use this method, the person must use a diesel emissions control strategy (DECS) with the engine, as set forth below:

a. Relative to the emissions without the use of the DECS, the engine with the DECS must be demonstrated to the E.O.'s written satisfaction as emitting at least 25 percent less diesel PM or NOx, and neither of those pollutants are increased by more than 10 percent. This requirement is met automatically if the DECS is a verified DECS (VDECS);
b. If the DECS is not a VDECS, the person must demonstrate compliance with this paragraph by submitting to the E.O. emissions data that demonstrate the non-verified emission control technology achieves a diesel PM or NOx emission reduction of 25 percent or better, using the test methods specified in subsection (q). Upon approval of the E.O., the person may submit data derived from the use of other test methods to demonstrate to the E.O.'s written satisfaction the required 25 percent minimum emission reductions, such as:
i. marine engine certification test data for the harbor craft propulsion or auxiliary engine, or engine manufacturer emissions test data;
ii. emissions test data derived from another engine that is configured and used in a substantially similar way to the in-use engine on which the emission control strategy is to be used; or
iii. emissions test data used to meet the regulatory requirements of the ARB Verification Procedure for the non-verified emission control strategy implemented.

The E.O. may, in his/her sole discretion and based on good engineering judgment, exclude any data derived from the test methods under paragraph b above that he/she determines are not reliable or credible.

A person's use of a DECS or VDECS, which meets the requirements of this provision, extends the engine's compliance date to the compliance date for a similar engine that is five model years newer (i.e., the actual model year for the engine with the emissions control strategy + 5).

[NOTE: For example, the owner of a 1995 model year engine on a tugboat, which has a homeport outside of SCAQMD and operates in Regulated California Waters for 750 hours in 2013, would normally be required to meet a December 31, 2014 compliance date, as set forth in Table 7. However, if a DECS that meets the requirements of this provision is implemented with this engine prior to the 2014 nominal compliance date, the engine's actual compliance date would be extended to the compliance date for a 2000 model year engine (i.e., the effective model year = the 1995 model year + 5). Accordingly, in that scenario, the engine's effective model year would extend the compliance date to December 31, 2016].

3.Method D3 -- the engine's effective model year based on the "Engine's Tier 1 Rebuild Model Year" method.

A person may determine an engine's compliance date by demonstrating, to the E.O.'s written satisfaction, that the engine is an existing pre-2004 model year engine that was rebuilt to conform with U.S. EPA Tier 1 marine standards prior to January 1, 2008. If the E.O. is thus satisfied, the effective model year of the Tier 1 rebuilt engine, for purposes of determining the compliance date in Table 7, Table 8, Table 9, or Table 10, is the actual year in which the Tier 1 rebuild occurred.

(E)Compliance Extensions.

Pursuant to this subsection (e)(6)(E), a person subject to the requirements of subsection (e)(6)(C) may request in writing to the E.O. an extension to a compliance date set forth in subsection (e)(6)(D) (i.e., extension to the "nominal" compliance date). The E.O. may grant the person an extension to the nominal compliance date for any one of the reasons set forth below. A person granted such an extension is deemed to be in compliance with the requirements of subsection (e)(6)(C) during the extension period, but only upon written authorization from the E.O. made pursuant to this provision and only until the end of the extension period. During the extension, the person must meet all other requirements of this section. Immediately upon the end of the extension period, the person must meet all the applicable requirements of this section.

Except as provided in paragraph (e)(6)(E)3 below, the E.O. may not combine compliance extensions granted pursuant to this provision with any other compliance date extensions, including those set forth in this provision and in subsection (e)(6)(D)2 and (D)3. And except as provided in paragraphs (e)(6)(E)2 and (e)(6)(E)3 below, under no circumstances may the E.O. grant more than one compliance extension for any individual engine, set of engines, or harbor craft.

1.Change in Annual Hours of Operation.

The E.O. may grant a one-time, maximum one year extension to the nominal compliance date set forth in subsection (e)(6)(D), provided the person demonstrates to the E.O.'s written satisfaction that all of the following have occurred:

a. The person reasonably determined the vessel engine's nominal compliance date based on the engine's hours of operation two years before the nominal compliance date; and
b. In the year immediately prior to the nominal compliance date, the engine's annual hours of operation increased significantly from the prior year such that the engine's nominal compliance date would have been accelerated from one compliance date to an earlier compliance date.

[NOTE: For example, suppose an operator has a 1982-model year engine on a tugboat, which has a homeport outside of SCAQMD and operates for 750 hours in Regulated California Waters in 2010. If it is reasonable for the operator to assume the annual hours of operation in 2011 will be similar to 2010, the operator would project from Table 7 that the engine's compliance date is December 31, 2012, and would plan his operations accordingly. However, if the vessel engine's operation increased substantially to 1600 hours in 2011, the engine normally would then have its compliance date accelerated to December 31, 2011, according to Table 7. The one-year extension would, therefore, extend the engine's actual compliance date back to what it would have been without the change in hours of operation (i.e., back to December 31, 2012).]

2.No Suitable Engine Replacement for Harbor Craft.

The E.O. may grant to a person a one year extension, which can be renewed annually, only if the person demonstrates to the E.O.'s written satisfaction that there is no suitable Tier 2 or Tier 3 marine or off-road-certified replacement engine available anywhere that can be used in the person's specific vessel, and the person cannot otherwise meet the requirements of subsection (e)(6)(C).

The E.O., in his/her sole discretion, may use any information available to the E.O. to rebut the person's demonstration. For purposes of this paragraph, the E.O. may deem an engine as suitable to replace an existing engine if the replacement engine is similar in horsepower to the existing engine, the replacement engine can fit within the vessel's engine compartment, and installation of the replacement engine would not cause the vessel to violate U.S. Coast Guard or other applicable safety regulations. The E.O. may not consider the cost of the replacement engine, by itself or including installation and downtime costs, in determining its suitability as a replacement.

The application for and issuance of an initial extension and subsequent extensions pursuant to this paragraph are subject to the following requirements:

a. For an initial extension and all subsequent annual extensions to be granted pursuant to this paragraph, the E.O. shall follow the same procedures for applying, determining completeness, allowing public review and considering public comments, taking final action, and publishing E.O. decisions that are set forth in subsection (f) for Alternative Control of Emissions (ACE) applications;
b. The E.O. shall consider all information submitted by the public regarding the availability of replacement engines suitable for the person's vessel;
c. Except for the engine(s) for which the extension is sought, the person must demonstrate that all other engines subject to the person's direct control meet the requirements of subsection (e)(6);
d. The person must submit the application for an extension so that it is received by the E.O. no later than 6 months before the nominal compliance date of the engine for which the extension is requested;
e. The person must identify in the application each engine for which the extension is requested;
f. For each engine identified in paragraph 2 above, the person must provide in the application a detailed description of the reasons and factors that serve as the basis for the claim that no suitable replacement engine is available. This description must include, at a minimum, detailed engineering diagrams, calculations, and citations to applicable U.S. Coast Guard regulations that support the person's claim that there are no suitable replacement engines available.
g. After the initial extension, the E.O. may grant additional one year extensions, provided the following requirements are met:
i. All procedures specified in paragraph (e)(6)(E)2.a and (e)(6)(E)2.b above are followed;
ii. The application for an additional extension demonstrates the engines identified in paragraph (e)(6)(E)2.c remain in compliance with this section;
iii. The application is received by the E.O. no sooner than 6 months but no later than 2 months before the expiration of the previous extension;
iv. The application identifies the engine(s) for which the additional extension is requested;
v. For each engine identified in paragraph (e)(6)(E)2.g.iv above, the person must provide in the application a detailed description of the reasons and factors that serve as the basis for the claim that suitable replacement engines remain unavailable. This description must include, at a minimum, detailed engineering diagrams, calculations, and citations to applicable U.S. Coast Guard regulations that support the person's claim that there are still no suitable replacement engines available.
3.Equipment Manufacturer Delays or Installation Difficulties.

Upon written request, the E.O. may grant to a person a 6-month extension to the nominal compliance date set forth in subsection (e)(6)(D), provided all the following criteria are met:

a. the person ordered the new replacement engine or other equipment necessary to comply with the requirements of subsection (e)(6)(C) prior to the nominal compliance date set forth in subsection (e)(6)(D);
b. the purchase order identified in paragraph a above was placed with the manufacturer no later than 6 months before the engine's nominal compliance date;
c. the new engine or equipment has not been received or installed since it was ordered due to manufacturing delays or excessive difficulties encountered by the engine or equipment installer; and
d. the applicant for the extension provides documentation to the E.O.'s satisfaction that demonstrates the criteria in subparts a. through c. above have been met. The E.O. may, in his/her sole discretion, use any information available to rebut any of the documentation submitted pursuant to subparts a through c above.
4.Multiple Engines on Multiple Vessels Within Same Fleet and With Same Compliance Dates.

This provision applies only to fleets of 2 or more vessels that are owned by the same person. Upon written request, the E.O. may grant to the person an extension to the nominal compliance date(s) for engines on vessels within such fleets, as set forth below;

a. For each set of engines on two or more vessels or for each single engine in three or more vessels with compliance dates of 2009 or 2010 for ferries, excursion vessels, tugboats, towboats, and push boats and 2011 or 2012 for crew and supply vessels and barge and dredge vessels (a "set" means 2 or more engines), the E.O. may grant a one-time extension of the compliance date to December 31, 2013 for ferries, excursion vessels, tugboats, towboats, and push boats and to December 31, 2015 for crew and supply vessels and barge and dredge vessels, provided the E.O. receives and approves a compliance schedule from the person that meets the requirements set forth below:
i. The compliance schedule is received by the E.O. no later than December 31, 2009 for ferries, excursion vessels, tugboats, towboats, and push boats and prior to December 31, 2011 for crew and supply, barge, and dredge vessels;
ii. For each year, up to and including 2013 for ferries, excursion vessels, tugboats, towboats, and push boats and 2015 for crew and supply vessels and barge and dredge vessels, that the extension will be in effect, the compliance schedule must identify, at a minimum, the engines on specified vessels in the fleet that will meet the requirements of subsection (e)(6)(C) within any given year;
iii. The compliance schedule must show that all engines with compliance dates of 2009 or 2010 for ferries, excursion vessels, tugboats, towboats, and push boats and 2011 or 2012 for crew and supply vessels and barge and dredge vessels on the specified vessels in the fleet will be in compliance with subsection (e)(6)(C) by December 31, 2013 for ferries, excursion vessels, tugboats, towboats, and push boats and December 31, 2015 for crew and supply vessels and barge and dredge vessels. [Note: For example, an approvable plan may show that 25% of these engines on the specified vessels in a fleet will be in compliance in 2010, 50% in 2011, 75% in 2012, and 100% by December 31, 2013.]; and
iv. The compliance schedule must include all other information the E.O. deems necessary and appropriate for implementing this provision.
b. For each set of engines on two or more vessels or each single engine on three or more vessels with a compliance date of 2011 or later for ferries, excursion vessels, tugboats, towboats, and push boats and 2013 or later for crew and supply vessels and barge and dredge vessels (a "set" means 2 or more engines), the E.O. may grant to a person a one-time, maximum one-year extension of the nominal compliance date. To receive an extension under this provision, the person must submit a written request to the E.O. that meets the following requirements:
i. The request must be received by the E.O. no later than December 31st of the year immediately preceding the nominal compliance date for the set of engines; and
ii. The request identifies the engines in each set of engines and the vessels in the person's fleet that are subject to the requested extension.

For all engines within a person's fleet that have not been granted an extension pursuant to paragraphs a or b above, the compliance dates for such engines remain as set forth in subsection (e)(6)(D).

(F)Special Provisions Applicable to the Use of a Diesel Emission Control Strategy (DECS), including Verified Diesel Emission Control Strategies (VDECS).

The following requirements apply to any person's use of a DECS pursuant to subsections (e)(5) or (e)(6) and are in addition to any other applicable requirements:

1. Once the DECS is installed or otherwise employed on a person's vessel, the person must continue to operate and maintain the DECS, in accordance with the manufacturer's directions, to achieve the original level of emission reductions that the DECS was designed and intended to achieve;
2. In the event a DECS fails, breaks down, or is otherwise damaged (collectively referred to hereinafter as "fail" or "failure"), the vessel owner or operator must, within 90 days of the DECS failure, do at least one of the following:
a. repair the DECS to good working order;
b. replace the failed DECS with another working DECS, if it cannot be repaired; or
c. employ another method that meets the requirements of subsection (e)(6)(C) and other applicable provisions of this section, if the DECS cannot be repaired.
3. The determination in subpart 2.b and 2.c above of whether a DECS cannot be repaired may only be made by either the DECS manufacturer or an authorized dealer.
4. For each replacement DECS installed under subpart 2.b above, the person must provide to the E.O. the same documentation for the replacement DECS that was required for the DECS that failed, and the person must obtain the same E.O. approvals that were required with the failed DECS.
(7)All Harbor Craft -- Renewable Diesel Fuel Requirements (Applicable On and After January 1, 2023).
(A) Beginning January 1, 2023, a person subject to this section shall only fuel a diesel engine on a harbor craft with R100 fuel or R99 fuel blend, except to demonstrate compliance with engine and fuel standards as specified in subsection (q).
(B) In the following situations, a harbor craft can be fueled with either: U.S. EPA on-road diesel fuel meeting the specifications contained in 40 CFR §§ 80.500 et seq., as they existed on April 27, 2010, or U.S. EPA nonroad diesel fuel meeting the specifications contained in 40 CFR § 80.29 as it existed on April 27, 2010, and 69 Federal Register 38958 (June 29, 2004), which are both incorporated herein by reference:
1. If a harbor craft subject to this section is traveling from a port located outside of California, and that port does not have R100 or R99. The vessel owner or operator must retain records documenting the fuel purchase, the location and the name of the non-California port, and its lack of availability of R100 or R99 fuel for a minimum of three years after the purchase of the fuel, and must make such records available upon the request of the E.O.; or
2. If, as of January 1, 2023, a vessel operator has an existing fueling contract, and the operator can demonstrate that the terms of the contract cannot be modified to supply R100 or R99. The vessel owner or operator must provide a copy of the documentation (such as the contract) to CARB. A vessel owner or operator must use R100 or R99 once the contractual issues no longer exist, or by December 31, 2025, whichever occurs sooner.
(8)All Harbor Craft (Excluding Commercial Fishing Vessels) -- Requirements for New and Newly Acquired Engines (Applicable On and After January 1, 2023).

Beginning January 1, 2023, any person subject to this subsection shall not sell, purchase, lease, rent, or import; offer for sale; or otherwise acquire or supply a new or in-use engine for a new or in-use harbor craft that is intended to operate or currently operates in RCW, unless that engine, on the date of acquisition, conforms to any one of the following subsections (A) through (E):

(A) Is certified to meet the most stringent marine standards (Tier 3 or Tier 4) or the Tier 4 Final off-road standards in effect on that date for a new engine with applicable horsepower rating and duty cycle rating, or is certified to meet both the most stringent marine standards (Tier 3 or Tier 4) or the Tier 4 Final off-road standards in effect on that date for a new engine with applicable horsepower rating and duty cycle rating and the applicable performance standards specified in subsection (e)(9) for a new engine of applicable horsepower rating and duty cycle rating.
1. A newly acquired marine engine rated below 600 kW is not required to meet the Tier 4 marine standards if there are no engines available on the date of acquisition that are certified to the Tier 4 marine emission standards for an engine of the same engine category and rated horsepower.
2. Engines certified to meet the Tier 4 Final off-road standards in effect on the date of acquisition for a new engine of applicable horsepower rating and duty cycle rating may only be acquired for use as an auxiliary or propulsion engine on harbor craft if the engine or vessel manufacturer has complied with 40 CFR § 1042.605(Marinized land-based engines already certified to other standards for nonroad or heavy-duty highway engines for marine use), as it existed on April 27, 2010, which is incorporated herein by reference.
3. Engines rebuilt to meet Tier 3 or Tier 4 marine standards or Tier 4 Final off-road standards may be acquired for use if the Tier 3 or Tier 4 marine standards or the Tier 4 Final off-road standards are the most stringent emission standards in effect on the date of engine rebuild for a new engine of the horsepower rating and duty cycle rating. For the purpose of demonstrating compliance with this provision, the person may, upon approval by the E.O., rely on any source of reliable and credible information. The E.O. will base their determination on the following information:
a. The results from using the test method specified in subsection (q) or an alternative method approved by the E.O.;
b. Engine manufacturer's certification test data or other emissions test data for that in-use engine;
c. Emissions test data derived from another in-use engine that is configured and used in a substantially similar way to the in-use engine;
d. Emissions test data used to meet the regulatory requirements of CARB's Verification Procedure for the non-verified emission control strategy implemented; or
e. For marine engines, emissions test data as specified in 40 CFR section 1042.835 (d), as last amended on June 30, 2008, and section 1042.840(n), as amended on October 25, 2016, which are incorporated herein by reference. For off-road engines, the information specified in 40 CFR section 1068.120 (j), as last amended on October 25, 2016, which is incorporated herein by reference.

The E.O. may, in their sole discretion and based on good engineering judgment, exclude any information they determine is not reliable or credible;

(B) Is newly acquired within the allowable six-month "sell-through" period. For purposes of this subsection only, the allowable sell-through period runs through six months after the date of the Tier 3 or Tier 4 marine standards or Tier 4 Final off-road standards have come into effect for a new engine of applicable horsepower rating and duty cycle rating as the engine being replaced. Engines that are subsequently sold, supplied, offered for sale, or otherwise newly acquired after the six month sell-through period are subject to the requirements specified in subsection (A) above;
(C) Is replacing an engine that is non-functioning due to equipment failure, and the E.O. has determined, pursuant to the engine replacement exemption provisions of 40 CFR § 1042.615, as it existed on April 27, 2010 and which is incorporated herein by reference, that no engine certified to the current standards is produced by any manufacturer with the appropriate physical or performance characteristics to repower the vessel. In such event, an alternate engine may be acquired for the replacement. Pursuant to 40 CFR § 1042.615, a separate determination addressing each tier of emission standards that is more stringent than the emission standards for the engine being replaced must be made. For example, if the engine being replaced was built before the Tier 3 standards were in effect, and engines of that size are currently subject to Tier 4 standards, a person must consider whether any Tier 3 or Tier 4 engines have the appropriate physical and performance characteristics for replacing the old engine. If a Tier 4 engine is determined not to have the appropriate physical and performance characteristics, but a Tier 3 engine does have the appropriate physical and performance characteristics, it must be selected as the replacement engine. In no case after a failure can the replacement engine be certified to a less stringent standard than the engine it is replacing. Documentation (e.g., an engineering evaluation) of these determinations must be supplied to the E.O. and the E.O.'s determination must be obtained before an engine replacement is made pursuant to this provision;
(D) Is replacing an engine the E.O. has approved for low use, as outlined in subsection (e)(6) prior to January 1, 2023, or subsection (e)(14) on or after January 1, 2023, as long as the new engine meets or exceeds the current engine's emission standards; or
(E) Is acquired for installation into a commercial passenger fishing vessel and the owner or operator has applied for and received the one-time, ten-year extension available to commercial passenger fishing vessels pursuant to subsections (e)(12)(E)3.a and (e)(12)(E)3.d.
(9)All Harbor Craft (Excluding Commercial Fishing Vessels) -- Requirements for New and Newly Acquired In-Use Harbor Craft (Applicable On and After January 1, 2023).
(A) Requirements for new harbor craft.
1. Beginning January 1, 2023, any person subject to this subsection shall not sell, purchase, lease, rent, or import; offer for sale; or otherwise acquire or supply a new harbor craft for use in any of the Regulated California Waters unless the tailpipe emissions from each propulsion and auxiliary engine on the vessel is certified to the most stringent marine standards (Tier 3 or Tier 4), or the Tier 4 Final off-road standards in effect on the date of vessel acquisition that are applicable to a new engine with applicable horsepower rating and duty cycle rating and the applicable performance standards defined in subsection (e)(9). Propulsion or auxiliary engines that are certified to the Tier 4 Final off-road standards in effect on the date of vessel acquisition for a new engine with applicable horsepower rating and duty cycle rating and that meet the applicable performance standards defined in subsection (e)(9) may be sold, purchased, offered for sale, leased, rented, imported, or otherwise acquired for use if the engine or vessel manufacturer has complied with 40 CFR § 1042.605 (Marinized land-based engines already certified to other standards for nonroad or heavy-duty highway engines for marine use), as it existed on April 27, 2010.
2. New vessels with engines rated less than 600 kW shall meet Tier 4 marine standards and the performance standards in Table 11 of subsection (e)(9) if Tier 4 marine engines are certified for the applicable horsepower rating and duty cycle rating on the date the keel is laid.
3. Methane (CH4) emissions from engines must not exceed 1.0 g/bhp-hr when using a gaseous or liquid fuel other than diesel.
4. Each propulsion and auxiliary engine on new excursion vessels and short-run ferries must be certified to the most stringent marine standards (Tier 3 or Tier 4) or the Tier 4 Final off-road standards in effect on the date of vessel acquisition that are applicable to a new engine with applicable horsepower rating and duty cycle rating, and must also meet applicable performance standards listed in subsection (e)(9) if the vessel is acquired on or after January 1, 2023, but prior to compliance dates as set forth in Table 14 in subsection (e)(10).
5. In the event Tier 3 or Tier 4 engines are available, but no engines or aftertreatment devices are available to meet Tier 3 + DPF or Tier 4 + DPF performance standards as shown in Tables 11 through 13, a person subject to this subsection must, prior to commencing construction on the new vessel, submit a request to the E.O. detailing the reasons why performance standards cannot be met. The E.O. may approve use of a certified Tier 3 or Tier 4 engine not meeting the performance standards shown in Tables 11 through 13 if the information submitted in the request and the exercise of good engineering judgment indicates the applicable performance standards cannot be met. Any engines on new vessels approved by the E.O. for use under this subsection shall be subject to requirements of subsection (e)(12) after the vessel commences operating in RCW. Notwithstanding the definition of "new harbor craft" in subsection (d), a new harbor craft whose keel was laid before January 1, 2023, is subject to the requirements of subsection (e)(12) instead of subsection (e)(9).

i. Vessels adopting zero-emission capable hybrid technology must demonstrate that 30 percent or more of combined main propulsion and auxiliary power will be derived from a zero-emission tailpipe emission source when averaged over a calendar year. Zero-emission power sources include battery plug-in hybrid propulsion systems using electricity from the electric grid or grid-neutral source, or hydrogen fuel cells, or other power sources with zero tailpipe emissions.
ii. Short-run ferries or other full zero-emission vessels must not use an internal combustion engine to generate propulsion or auxiliary power for the normal operation of the vessel (more than 20 hours/year) unless the engine meets the emission limits for distributed generation or is used exclusively during emergency operations. Use of internal combustion engines for emergency operation is permitted but subject to recordkeeping requirements in subsection (m)(19).
d. Information and plans for charging or fueling infrastructure that include an overall description of the frequency and duration of charging or fueling, a list of key hardware components, and applicable documentation of communication with utility companies, fueling contracts with hydrogen providers, or installation of on-site fueling systems.
e. The proposed recordkeeping, reporting, monitoring, and if applicable, testing procedures that the applicant plans to use to demonstrate continued effectiveness of the ZEAT. Recordkeeping and reporting must include, at a minimum, the requirements in subsection (m)(19).
2. E.O. Review and Final Decision-Making Process.
a. Within 30 days after receiving a ZEAT application, the E.O. shall notify the applicant whether the application is deemed sufficiently complete to proceed with further evaluation. If the application is deemed incomplete, the notification must identify the application's deficiencies. The applicant must submit supplemental documentation within 30 days of receiving a notification indicating the application is incomplete. The E.O. shall have an additional 30-day period for reviewing each set of documents or information submitted in response to an incomplete determination.
b. Within 60 days of deeming an application complete, the E.O. shall take final action to either approve or deny a ZEAT application, and the E.O. shall notify the applicant accordingly. In approving or disapproving a ZEAT application, the E.O. will base their determination on the information submitted in the ZEAT application and their exercise of good engineering judgment. If the application is denied or modified, the E.O. shall state the reasons for the denial or modification in the notification. The E.O. shall specify all terms, conditions, and requirements the E.O. determines are necessary for the applicable vessel to operate properly and reduce emissions of air pollutants consistent with this section.
(11)ZEAT Credit for Early or Surplus Deployments (Applicable On and After January 1, 2023).
(A) Applicability.

If a person adopts a ZEAT on new or newly acquired excursion vessels or short-run ferries no later than three years prior to compliance dates shown in Table 14, or at any time for any other category of vessel, the person may be granted additional compliance time as set forth in Table 15 for another excursion vessel or short-run ferry subject to subsection (e)(10), for all in-use engines to meet performance standards in subsection (e)(12) on another vessel in any regulated in-use category, or for all in-use engines to meet the requirements for commercial fishing vessels in subsection (e)(13) that is under a person's direct control and operating within the same California air basin.

Table 15. ZEAT Credit Time for Surplus ZEAT Deployment

Marine Technology TypeAdditional Compliance Time
Zero-Emission Capable Hybrid3 Extra Years
Zero-Emission7 Extra Years

NOTE: The ZEAT credits in Table 15 are only issued in three- and seven-year increments, subject to the condition that the length of the additional compliance time may not extend beyond December 31, 2034, pursuant to subsection (e)(11)(B)7.

For example, a pilot boat, which is not subject to ZEAT requirements as set forth in subsection (e)(10) but must meet Tier 4 + DPF performance standards as set forth in subsection (e)(12) by December 31, 2027, is removed from service and replaced with a zero-emission vessel on December 31, 2026. In this scenario, the owner or operator of the pilot boat may request that CARB grant seven additional years to the compliance date for another vessel in the owner or operator's fleet that is operating in the same air basin, to comply with requirements of subsection (e)(12). However, the additional compliance time may not extend past December 31, 2034.

(B) Eligibility and Requirements for Receiving ZEAT Credit.
1. Before applying the ZEAT credit to another vessel in their fleet, the ZEAT vessel generating the credit must be deployed and operational.
2. Vessels that are part of an Alternative Control of Emissions (ACE) as set forth in subsection (f) are not eligible to generate or receive a ZEAT credit pursuant to this subsection.
3. ZEAT vessels deployed using incentive funding are eligible to generate ZEAT credit unless restricted by guidelines for the incentive funding program.
4. ZEAT vessels deployed in RCW prior to or after January 1, 2023 are eligible to generate ZEAT credit.
5. ZEAT credit can only be applied to vessels with engines certified to Tier 2 or more stringent emission standards.
6. Receiving a ZEAT credit for engines or vessels in a person's fleet does not preclude a person from applying for feasibility extensions set forth in subsections (e)(12)(E)2.-4. after the expiration of the ZEAT vessel credit.
7. Any ZEAT credit or combination of ZEAT credits and compliance extensions shall not extend the compliance date of any engine or vessel beyond December 31, 2034.
8. ZEAT credit may be applied to vessels with a homebase or regularly scheduled stops within two miles of a Disadvantaged Community (DAC) only if the ZEAT vessel deployed to generate the ZEAT credit also has a homebase or regularly scheduled stops within two miles of any DAC.
9. A person is eligible to receive the ZEAT credit time shown in Table 15 without an analysis of emissions showing that deploying the ZEAT vessel achieves equal or greater emission reductions within their fleet. Emissions analysis is required for zero-emission capable hybrid vessels in partial fulfillment of meeting requirements of CARB approval of technologies as listed in (e)(10)(C)1.a-e.
10. The ZEAT credit applies one time only to each ZEAT vessel when it is first put into service in RCW. The ZEAT credit applies to one selected vessel in the owner's or operator's fleet and is not transferable to another vessel within the fleet or to a subsequent owner after the sale of the ZEAT vessel.
(C) ZEAT Credit Application Process.
1. At least nine months prior to the compliance date of engines/vessel receiving the ZEAT credit, an applicant must submit an application to and receive written approval from the E.O. The application package must include the following information:
a. The applicant company's name, address, and contact information;
b. ZEAT vessel information, including vessel name, vessel unique identifier and homebase, and supplemental documentation demonstrating the deployed ZEAT vessel meets the performance standards and requirements set forth in subsection (e)(10)(C)1.a-e.; and
c. Identification of the specific harbor craft and engine(s) for which the applicant proposes to apply ZEAT credit, including vessel name, identification number(s) and homebase; engine make(s), model(s), model year, and serial number(s).
2. Within 30 days after receiving a ZEAT credit application, the E.O. shall notify the applicant whether the application is deemed sufficiently complete to proceed with further evaluation. If the application is deemed incomplete, the notification must identify the application's deficiencies. The applicant must submit supplemental documentation within 30 days of receiving a notification indicating the application is incomplete. The E.O. shall have an additional 30-day period for reviewing each set of documents or information submitted in response to an incomplete determination. Nothing in this subsection prohibits the E.O. from requesting additional information from the applicant, during any part of the ZEAT credit application process, that the E.O. determines is necessary to evaluate the application.
3. Applicants with an approved ZEAT credit must notify the E.O. in writing within 30 days upon learning of any information that would alter the analysis submitted. If the E.O. has information that indicates an approved ZEAT credit has been granted that no longer meets the criteria for a ZEAT credit, the E.O. may modify or revoke the credit as necessary to ensure that the applicant and subject vessel(s) meet the emission reduction requirements in this section.
4. Records made pursuant to subsection (e)(11) shall be kept for the lifetime of each engine receiving the ZEAT credit. This information shall be supplied to the E.O. within 30 days of a request from CARB staff.
(12)In-Use Engines and Vessels (Excluding Commercial Fishing Vessels) -- Requirements for Meeting Performance Standards (Applicable On and After January 1, 2023).
(A)Applicability. For Any Engines on Regulated In-Use Vessels.
1. For purposes of this subsection, regulated in-use vessels include ATBs, barges (including tank barges, and barges operating as part of ATBs), commercial passenger fishing vessels, crew and supply vessels, dredges, excursion vessels, ferries (excluding in-use short-run ferries), pilot vessels, push boats, research vessels, tugboats (including ocean-going tugboats or towboats, and tugboats operating as part of ATBs), towboats, and workboats.
2. This subsection applies on and after January 1, 2023, to any person who owns or operates a regulated in-use vessel with any marine or off-road engines operating more than the annual low-use hour limits specified in Table 22 in subsection (e)(14).
(B)General Requirements.
1. On and after January 1, 2023, no person may operate, sell, purchase, offer for sale, lease, rent, import, or otherwise acquire a regulated in-use vessel, unless each engine or engine system on the vessel complies with at least one of the compliance methods set forth in subsection (e)(12)(C) by the applicable compliance date. Engines approved to operate as low-use pursuant to subsection (e)(6)(C)(4) prior to January 1, 2023, must continue to meet low-use limits defined in subsection (e)(6) until compliance dates set forth in subsections (e)(12)(D)-(E).
2. In-use engines rated below 600 kW shall not be repowered with engines meeting Tier 3 marine standards if an engine with the applicable horsepower and duty cycle rating certified to the Tier 4 marine standards is available. If engines meeting Tier 4 marine standards are not available under 600 kW, and engines are repowered on or after January 1, 2023, to the Tier 3 marine standards, they would not need to be repowered to Tier 4 marine standards when engines meeting Tier 4 marine standards become available.
3. In-use engines rated below 600 kW that meet Tier 3 marine standards before January 1, 2023, are subject to Tier 4 marine standards if an engine of the applicable horsepower rating and duty cycle is available 12 months prior to the compliance date unless after January 1, 2023, no engines meeting Tier 4 marine standards are available and the Tier 3-compliant engines are retrofitted with a DPF and meet Tier 3 marine + DPF standards by applicable compliance dates.
4. In-use engines or engine systems rated above 600 kW shall meet Tier 4 marine + DPF or Tier 4 Final off-road + DPF performance standards under this subsection. If no engines with the power and duty cycle ratings needed by the vessel that meet the Tier 4 marine + DPF performance standards or the Tier 4 Final off-road + DPF performance standards are available 12 months prior to the compliance date, the vessel owner would be eligible for a compliance extension as set forth in subsection (e)(12)(E) provided that all criteria in subsection (e)(12)(E)2. are satisfied. Early upgrades before compliance dates of engines rated above 600 kW that meet Tier 3 marine or off-road standards must still repower with engines meeting Tier 4 marine or Tier 4 Final off-road standards.
5. If an in-use ZEAT short-run ferry operates in other regulated in-use vessel categories as a secondary or other use, or if an in-use commercial fishing vessel operates in other regulated in-use vessel categories as a secondary or other use, operation of the secondary or other use is subject to the requirements of this subsection and may be eligible for a low-use exception as defined in subsection (e)(14) based on engine tier level and operating hours.
6. In situations where in-use engines that are subject to the requirements of subsection (e)(12) do not meet performance standards but remain installed on the vessel, the vessel owner/operator must take actions to ensure the non-compliant engines cannot be operated. Examples include electrically or mechanically disabling the engine to prevent operation, or permanently disconnecting fuel lines. The owner/operator of non-operational engines must meet applicable recordkeeping and reporting requirements in subsections (m) and (o).
7. Vessel owners or operators who need to continue to operate engines after applicable compliance dates of this subsection to perform emissions testing to support verification of a DECS, perform emissions testing to demonstrate compliance of their engines or vessel with requirements of subsection (e), collect data to support an ACE plan, sell a CHC that is only intended to operate beyond RCW but will perform sea trials in RCW, or transit through RCW from the seller to the buyer, must first request and receive written approval from the E.O. At least 14 days prior to the planned operation, the owner/operator must submit a formal request, including the vessel name, unique vessel identifier, engine make, model, model year, serial number, an estimate of operating hours for the planned operation in RCW on each non-compliant engine, the dates and locations of operation, and demonstrate what efforts will be taken to minimize the number of operational hours of non-compliant engines. The E.O. will base their determination on the information submitted and on the exercise of good engineering judgment whether the request comprises a good faith attempt to minimize the operation of that CHC in RCW.
(C)Compliance Methods.

Regulated in-use vessels with pre-Tier 1- or Tier 1-certified engines may follow any of the below applicable compliance methods (e)(12)(C)(1) through (3) to comply with the performance standards set forth in subsection (e)(9).

1.Method C1 -- Replace the in-use engine with a U.S. EPA certified Tier 3 or Tier 4 marine engine or Tier 4 Final off-road engine that also meets CARB performance standards in its certified condition by U.S. EPA or CARB.

A person may comply under this method by replacing the in-use engine with an engine certified to the most stringent marine standards (Tier 3 or Tier 4), or Tier 4 Final off-road engine emission standards applicable to a new engine with the applicable horsepower rating and duty cycle rating as the in-use engine at issue and that meets the applicable performance standards in subsection (e)(9) in its certified condition by U.S. EPA or CARB. The replacement engine must meet CARB defined performance standards that would apply to a new engine, of the applicable horsepower rating and duty cycle rating as the in-use engine, at the time of the compliance date set forth in subsection (e)(12)(D) plus any compliance extensions approved pursuant to subsection (e)(12)(E).

2.Method C2 -- Repower or rebuild the in-use engine with a U.S. EPA certified Tier 3 or Tier 4 marine engine or U.S. EPA or CARB certified Tier 4 Final off-road engine that does not meet CARB performance standards and install a CARB Level 3 verified diesel emission control strategy (Level 3 VDECS or DPF).

If an engine does not meet the most stringent marine standards (Tier 3 or Tier 4), or Tier 4 Final off-road standards applicable to a new engine with the applicable horsepower rating and duty cycle rating as the in-use engine at issue, and the applicable performance standards in subsection (e)(9), a person may comply under this method by repowering or rebuilding the in-use engine with an engine certified to the most stringent marine standards (Tier 3 or Tier 4), or Tier 4 Final off-road engine emission standards applicable to a new engine with applicable horsepower rating and duty cycle rating as the in-use engine and by additionally retrofitting the engine with a DPF.

3.Method C3 -- Demonstrate to the E.O.'s satisfaction that the tailpipe emissions meet the performance standards using Alternative Control of Emissions.

A person may comply under this method by demonstrating that the tailpipe emissions meet the most stringent marine standards (Tier 3 or Tier 4), or Tier 4 Final off-road standards applicable to a new engine with the applicable horsepower rating and duty cycle rating as the in-use engine at issue, and also the applicable performance standards in subsection (e)(9). To comply with this method, the applicant must follow the provisions set forth in subsection (f).

4.Method C4 -- Meet CARB performance standards using a two-step phase-in method (pre-Tier 1 and Tier 1 engines only).

Any pre-Tier 1 or Tier 1 certified engines on regulated in-use vessels may meet CARB performance standards using the phase-in method described below:

a. Replace the in-use pre-Tier 1 or Tier 1 certified engine with an engine meeting the most stringent standards (Tier 3 or Tier 4 marine; or Tier 4 Final off-road) for a new engine with the applicable horsepower rating and duty cycle rating as the in-use engine by the compliance date set forth in Table 16 in subsection (e)(12)(D) or (e)(12)(E) if compliance extensions are approved. The replacement engine must meet the provisions of subsection (e)(8).
b. Retrofit the U.S. EPA certified Tier 3 or Tier 4 marine or Tier 4 Final off-road engine with a DPF by the compliance date set forth in Table 17, Table 18 or Table 19 in subsection (e)(12)(D) or (e)(12)(E) if compliance extensions are approved. If Tier 3 or Tier 4 engines already meet the applicable performance standards set forth in subsection (e)(9) in their certified condition, retrofitting with a DPF is not required.
(D)Compliance Dates.

Table 16, Table 17, Table 18, and Table 19 below set forth the compliance dates by which a person must demonstrate that a regulated in-use vessel or engine meets the requirements of subsection (e)(12)(B). Table 16 applies only to any pre-Tier 1 and Tier 1 certified engines on regulated in-use vessels that were not subject to the in-use engine compliance requirements prior to January 1, 2023; Table 17 applies only to Tier 2, Tier 3, or Tier 4 engines on ferries (except for short-run ferries), pilot vessels, all tugboats, towboats, and push boats; Table 18 applies only to Tier 2, Tier 3, or Tier 4 engines on research vessels, commercial passenger fishing vessels, and in-use excursion vessels, and Table 19 applies to Tier 2, Tier 3, or Tier 4 engines on barge and dredge vessels, crew and supply vessels, and workboats. The compliance dates are set forth by engine model year. For Table 16, Table 17, Table 18, and Table 19, Method D1 or D2 below may be used for determining the actual or effective engine model year.

1.Method D1 -- the engine's actual model year.
a. A person may determine an engine's compliance date under this method by using the engine's actual model year of manufacture, as documented by the sales contract, invoice, purchase order, or other proof of purchase for the engine. The actual model year of manufacture may also be shown on a label permanently affixed to the engine by the original engine manufacturer (OEM). In the event of a conflict between the proof of purchase and the permanent label, the earlier of the two dates shall be used for the purpose of this provision.
b. Using Method D1, with the exception of engines complying under subsection (e)(12)(C)4.b., the compliance date for an engine is based on the model year of the in-use engine that was installed in the in-use vessel as of December 31, 2022. For in-use vessels that are in the process of an engine replacement so that there is no engine installed in the vessel on December 31, 2022, the compliance date is determined by the model year of the next engine that is installed in the vessel.
2.Method D2 -- the engine's effective model year based on the engine's Tier 3 or Tier 4 rebuild model year.
a. A person may determine an engine's compliance date by demonstrating, to the E.O.'s written satisfaction, that the engine was rebuilt to conform with U.S. EPA Tier 3 or Tier 4 marine standards.
b. For the purpose of the demonstration, the person must submit the following information to validate the criterion set forth in subsection (e)(12)(D)2.a.: proof of ownership of the preexisting engine, receipts or work orders evidencing that the engine was rebuilt to conform with Tier 3 or Tier 4 marine engine standards and the date the rebuild was completed, and emissions test data from the rebuilt engine demonstrating compliance with U.S. EPA Tier 3 or Tier 4 marine engine standards.
c. An owner or operator electing to use Compliance Method D2 must submit the information specified in subsection (e)(12)(D)2.b. to the E.O. The E.O. will review the information and determine, within 30 working days, whether the information meets the criterion set forth in subsection (e)(12)(D)2.a. In making that determination, the E.O. will rely on the information submitted by the applicant and on good engineering judgment.
d. If the E.O. determines that the information satisfies the criterion set forth in subsection (e)(12)(D)2.a., the effective model year of the Tier 3 or Tier 4 rebuilt engine, for purposes of determining the compliance date in Table 17, Table 18, or Table 19, is the actual year in which the Tier 3 or Tier 4 rebuild occurred.
e. Using Method D2, with the exception of engines complying under subsection (e)(12)(C)4.b., the compliance date for an engine is based on the model year for the in-use engine that was installed on the in-use vessel as of December 31, 2022. For in-use vessels that are in the process of an engine replacement so that there is no engine installed in the vessel on December 31, 2022, the compliance date is determined by the model year of the next engine that is installed in the vessel.

(E)Compliance Extensions.

A person may request that the E.O. grant an extension from the compliance dates forth in subsection (e)(10), (e)(12), (e)(13), or (i)(1) for infrastructure, feasibility, or scheduling delays. Compliance extensions are not transferrable to a subsequent owner after the sale of an engine or vessel. Except for Extension E5 for shipyard delays for new build vessels, owners/operators are not eligible to apply for extensions for newly acquired harbor craft.

With the exception of Extensions E2, Extension E3 for workboats pursuant to subsection (e)(12)(E)3.c.ii., and Extension E4, no extensions may extend beyond December 31, 2034.

With the exception of Extensions E2, Extension E3 for workboats pursuant to subsection (e)(12)(E)3.c.ii, and Extension E4, extensions may be combined, but the combination of extensions may not result in an extension for a single engine more than six years after the compliance date, or for more than eight years after the compliance date for vessels specified in subsection (e)(12)(E)3.c.i.

For each initial extension or renewal of an extension, the E.O. will review the application upon receiving a complete application. The E.O will approve or disapprove the requested compliance extension or renewal by relying on the information in the application, technical feasibility, and product availability as of the date of the deadline of the application, and their good engineering and financial judgment. If an applicant seeks a renewal of an extension, they must submit the same information required for the initial application.

1.Extension E1: Shore Power and ZEAT Infrastructure Delays.
a.Length of Extension: The E.O. may grant an applicant a one-year compliance extension to the compliance date set forth in subsection (i)(1) for shore power or subsection (e)(10) for ZEAT.
b.Eligibility and Application Package: The applicant, whether a vessel or facility owner or operator, shall submit an application to the E.O. at least nine months prior to the compliance date, or as specified in subsection (e)(12)(E)1.c. for a renewal, that includes the following information:
i. Start and end dates of the requested extension period;
ii. A description of the unforeseen, temporary, or extenuating circumstances outside of the applicant's control;
iii. Documentation that supports the finding of circumstances requiring an extension, including documentation from the electrical utility, third-party engineering evaluations, or site-specific physical constraints requiring additional time for safety review; and
iv. Efforts taken to mitigate future need for the extension.
c.Renewal: The applicant may apply for an additional one-year extension no later than nine months and no earlier than 12 months before the expiration of the prior extension.
2.Feasibility Extension E2 -- No Certified Engines or DPFs Available.
a.Length of Extension: The E.O. may grant an applicant a two-year compliance extension to the compliance dates set forth in subsection (e)(8), (e)(9), or (e)(12).
b.Eligibility and Application Package: The applicant must demonstrate that there are no certified engines or DPFs available to meet performance standards by applicable compliance dates. The application package must be submitted to the E.O. no later than nine months and no earlier than 12 months before the compliance date for the initial application or as specified in subsection (e)(12)(E)2.c. for a renewal, and must include:
i. An evaluation of all U.S. EPA-certified engines meeting applicable performance standards by the compliance date;
ii. An evaluation of all CARB verified DPFs by the compliance date; and
iii. An engineering analysis indicating that no combination of certified engines could be used in lieu of engines of the original horsepower rating to perform the work of the original vessel design. This analysis must consider all engines within an applicable range of power ratings, power densities, and other vessel powertrain modifications, including engine controls, azimuth drives and propeller configurations.
c.Renewal: The applicant may apply for an additional two-year extension no later than nine months and no earlier than 12 months before the expiration of the prior extension.
d.Additional Provisions:
i.Cleanest Engine Requirement: In situations where engines certified to current Tier 3 marine, Tier 4 marine, or Tier 4 Final off-road standards are available but DPFs are not available, a person must repower the vessel's engines with an available Tier 3 marine, Tier 4 marine, or Tier 4 Final off-road engine by applicable compliance dates to receive an extension for DPFs. Compliance dates shown in Tables 11, 12, and 13 are based on the model year of the original in-use engine. The person must retrofit the vessel with a DPF within six months after a DPF becomes available for the engine installed on the vessel or by the expiration date of the last compliance extension granted, whichever is sooner.
ii. Unavailability of a DPF for a Specific Engine Manufacturer or Model: If a person repowers with a Tier 3 marine, Tier 4 marine, or Tier 4 Final off-road engine after January 1, 2023, they will not have to replace the engine with one of a different model if a DPF becomes verified for that other engine model. A person applying for this extension must also repower their engine with one certified to a more stringent standard and must consider all available engines for the power and duty cycle rating of their operation, regardless of engine manufacturer or engine model.
3.Feasibility Extension E3 -- Engines or DPF not Feasible and Owner Cannot Afford Vessel Replacement.
a.Length of Extension: The E.O. may grant an applicant either a two-year compliance extension to the compliance date for any regulated in-use vessel category set forth in subsection (e)(12) or, for engines on commercial passenger fishing vessels meeting either Tier 3 or more stringent emission standards by December 31, 2024, a one-time, ten-year extension until December 31, 2034.
b.Eligibility and Application Package (does not apply to ten-year extensions available to commercial passenger fishing vessels as set forth in subsections (e)(12)(E)3.a. and (e)(12)(E)3.d.): The applicant must demonstrate that no suitable engines (Tier 3 or Tier 4 marine, or Tier 4 Final off-road) or CARB-verified DPFs physically fit within the existing vessel structure, and no amount of modifications can be made to the vessel structure without compromising its structural integrity or stability, to meet requirements of subsection (e)(12). The applicant must also demonstrate that removing the vessel from service and replacing it with a newly acquired vessel with compliant engines is not financially possible. The application package must be submitted to the E.O. no later than 18 months before the compliance date of the engine(s) or vessel(s) for which the extension is requested or as specified in subsection (e)(12)(E)3.c. for a renewal, or no later than nine months before the December 31, 2023 compliance date, and must include:

ii. For extensions to installing DPFs, technical feasibility analysis demonstrating that no DPF can be used to retrofit Tier 3 or Tier 4 engines on the vessel;
iii. For extensions to repowering engines or installing DPFs, vessel-specific technical feasibility analysis provided by a third-party naval architect demonstrating that no modifications are feasible to repower and retrofit the vessel. Non-vessel-specific third-party naval architect analyses for vessels with hull materials of wood, fiberglass, or fiberglass-reinforced plastic can only satisfy this requirement for the initial two-year extension;
iv. For extensions to repowering engines or installing DPFs, modifications resulting in a passenger capacity reduction of 25 percent or more are considered not feasible if supporting documentation demonstrates that reducing passenger capacity will operationally result in increased emissions;
v. The following information, if available:
1) at least three years of federal and State income tax documents,
2) at least three years of Profit and Loss statements;
vi. A list of actions that the applicant has taken to comply or in anticipation to comply with the regulation at the earliest compliance date and supporting documentation to demonstrate that these actions have been taken. Such actions may include developing new business structures (e.g., forming a new corporation) or restructuring existing accounting practices to pass some or all of the compliance costs associated with this regulation onto the consumers and entities receiving the applicant's services, replacing existing engines with engines certified to more stringent marine engine or off-road certification standards, and procuring loans to finance anticipated compliance costs; and
vii. A list of engine(s) for which the extension is(are) requested, and documentation demonstrating that all other engines within the fleet subject to the applicant's direct control meet the requirements of this section.
c. Renewal: If an applicant receives a two-year extension, the applicant may apply for an additional two-year extension no later than nine months and no earlier than 12 months before the expiration of the prior extension. No further compliance extensions of this type can be approved if either six years of any extension have been granted or if compliance dates for any engine will be extended beyond December 31, 2034, except that:
i. Commercial Passenger Fishing Vessels, Excursion Vessels, and Ferries, which can receive an additional extension of two years for a total of eight years if the vessel has any nominal compliance deadline on or before December 31, 2024; and
ii. Vessels operating any number of hours as a workboat that do not operate more than the hours listed in Table 22, in any other category of vessel, which can receive an unlimited number of extensions. To be eligible for unlimited extensions in effect at any time after December 31, 2034, engines on workboats must meet at least Tier 3 marine or off-road emission standards.
d.Application Criteria (subsections i.-iv.) and Other Provisions (subsections v.-vii.) for Ten-Year Extensions Available to Commercial Passenger Fishing Vessels:

Supporting documents (such as logbooks or records indicating hour meter readings on past dates) to demonstrate that the engine was not operated more than the limits specified in Table 22 in the previous calendar year (January 1 to December 31), and is not expected to operate more than the specified limits in the current year. If the application is for a vessel based outside of RCW that is scheduled to enter RCW for the first time, no demonstration of annual operation hours in the previous or current calendar year to date is required;
d. Activity plans or commitments demonstrating that the engine will not operate more than the limits specified in Table 22 in the subsequent years following the demonstration;
e. If engines are used non-commercially, such as for personal pleasure, those operating hours do not count toward the limits specified in Table 22 only if such hours are clearly documented in logbooks for past operation and future activity plans demonstrate how future regulated commercial operation will remain below applicable limits; and
f. The vessel name and UVI of all other vessels in that fleet that have approved low-use exceptions and are operating within RCW in the current calendar year.
3. In granting or denying the extension request, the E.O. will rely on the information submitted by the applicant and utilize their engineering judgment to evaluate whether the information meets the criteria in subsections (e)(14)(B) and (C).
(f)Alternative Control of Emissions (ACE).

The purpose of this subsection is to allow a person ("person" or "applicant") the option of applying alternative strategies to achieve equivalent or additional emission reductions relative to requirements of subsection (e)(7), (e)(10), (e)(12), or (e)(13).

(1) Requirements for ACE.
(A) An applicant must establish that the ACE achieves equivalent or greater emissions reductions than if the applicant were to directly comply with subsection (e)(10), (e)(12), and (e)(13), which is considered the Nominal Compliance Baseline. The ACE can include an alternative emission control strategy(ies) (AECS) approved by the E.O. as set forth in subsection (f)(1)(E) below. For the purpose of demonstrating equivalent or greater emission reductions, the applicant must evaluate emission reductions of PM and NOx that are projected to result from an AECS for a time period from January 1, 2023, through December 31, 2034, relative to the Nominal Compliance Baseline with a maximum of two years of any feasibility extension with documentation submitted according to the requirements as set forth in subsection (e)(12)(E)2.-4. Engine repowers, retrofits, or other strategies (such as ZEAT) that were in place as of January 1, 2023, can be included in an applicant's ACE for the time period of January 1, 2023, through December 31, 2034, only if they were surplus to requirements of subsections (e)(3), (e)(4), (e)(5), and (e)(6). All engines receiving extensions as part of an ACE plan must meet the applicable compliance requirements of subsections (e)(7), (e)(10), (e)(12), and (e)(13) by December 31, 2034.
(B) An applicant wishing to participate in an ACE may include one or more harbor craft in the ACE, but the applicant may only include harbor craft that the person owns or operates under the person's direct control.
(C) No harbor craft may be included in more than one ACE plan.
(D) Harbor craft included in an ACE must continue to be included in and operated pursuant to the approved ACE for the duration of the ACE.
(E) AECS may only apply to emissions from harbor craft subject to this section, and may not apply to other mobile or stationary source categories. AECS may include any combination of the following:

6. fleet averaging, including ZEAT vessels unless they have been separately used to generate a ZEAT credit or had their compliance date extended by applying a ZEAT credit as set forth in subsection (e)(11);
7. CARB Approved Emission Control Systems (CAECS) may be used in an ACE application to meet the performance standards required in subsection (e)(12). To receive the E.O.'s approval, the CAECS must be:
a. approved pursuant to section 93130.5, and
b. the applicant must demonstrate that the CAECS is applicable to the harbor craft specified in the application and meets applicable performance standards. For purposes of the demonstration, the E.O. may request additional emissions testing based on good engineering judgment; and
8. any other measures that sufficiently reduce emissions.
(F) A person complying under this provision must obtain E.O. approval of an ACE application that demonstrates compliance with this subsection and contains, at a minimum, the following information:
1. the company name, address, and contact information;
2. the harbor craft and engine(s) subject to the ACE, including the vessel name and identification number(s), engine make, model, and serial numbers, and other information that uniquely identify the engine;
3. documentation, calculations, emissions test data, or other information that establishes the diesel PM and NOx reductions, expressed in pounds, are equal to or greater than the emission reductions that would have been achieved upon compliance with subsection (e);
4. the proposed recordkeeping, reporting, monitoring, and testing procedures that the applicant will use to demonstrate continued compliance with the ACE; and
5. Applicants must submit the following information to demonstrate that their ACE will not result in a higher emissions burden to DACs relative to other communities impacted by the emissions from their vessel operations: the homebase and the information specified in subsection (m)(14)(E) of each harbor craft in an applicant's existing fleet, the proposed homebase and the information specified in subsection (m)(14)(E) describing where the proposed ACE harbor craft vessels will primarily operate in RCW, and the operating hours that each proposed ACE harbor craft vessel will operate in RCW each calendar year.
(G) For each ACE, the emission reduction calculations demonstrating equivalence with the requirements of subsection (e)(7), (e)(10), (e)(12), or (e)(13) may include only those diesel PM and NOx emissions from harbor craft within the applicant's fleet that operate within a single specified California air basin, or another defined geographic area approved by the E.O.
(H) A person subject to an approved ACE must maintain operating records in the manner and form as specified by the E.O as an element of any approved ACE. Required records must include, at a minimum:
1. all the reporting and recordkeeping requirements specified in subsection (m) and (o) on and after January 1, 2023;
2. maintenance procedures; and
3. emissions test results.

A person subject to an approved ACE must retain records and reports for the lifetime of each engine and must submit these records and reports to the E.O. in the manner specified in the approved ACE or upon request by the E.O.

(I) Emission reductions included in an ACE may not include reductions that are otherwise required by any local, State, or federal rule, regulation, or statute, or that are achieved or estimated from equipment not located in the region to which the ACE applies. The ACE application must not include emissions reductions attributed to equipment acquired by funds or grants that prohibit use of funds to comply with State regulations, laws, or mandates.
(J) A person subject to an approved ACE may not operate any harbor craft under the ACE unless the person has first been notified in writing by the E.O. of the ACE's approval. Prior to such approval, the applicant must comply with the provisions of this section, including the requirements in subsections (e)(7), (e)(10), (e)(12)(C), (e)(12)(D), and (e)(13) on and after January 1, 2023.

4. CARB UVI shall be affixed to or painted on both sides of the pilot house in a visible location but not obstructing captain/pilot view. If the vessel does not have a pilot house, another visible location on both sides of the vessel must be selected.
5. Marking shall be maintained in a manner that retains the legibility required by subsections 1.-4. immediately above.
(C) The owner or operator of a registered historic vessel may install a cast bronze, brass, or carved wooden plaque, or other UVI format, that meets the specifications in subsections (g)(2)(B)1., 2., 4., and 5.
(h)Main Engine Idling and Auxiliary Engine Operating and Idling Limits.

All harbor craft subject to this section shall meet the following requirements.

(1) Except as provided in subsections (1)(A)-(E) below, beginning on January 1, 2024, no vessel subject to this subsection shall idle propulsion engines, or idle or operate auxiliary engines with a power rating of 99 kW or less, for more than 15 consecutive minutes when docked, berthed, or moored at any facility. Quick engine accelerations, restarting the engine while otherwise idling, or other operational maneuvers intended to circumvent the idling limit are still considered continuous idling. The idling and operational limits do not apply to:
(A) Idling at dedicated facilities used for the testing, servicing, or repairing of engines;
(B) Operation of auxiliary engines that are not electric generators;
(C) Idling or operation during emergency operations as defined in subsection (d);
(D) Idling or operation at facilities where shore power is not available or not required pursuant to vessel visit thresholds as defined in subsection (i); and
(E) Idling or operation of up to 30 consecutive minutes for the initial start-up of a vessel each day, after a vessel arrives at a dock at the end of a work period, or prior to initial operation in a new work period after engines are restarted, or when a shift or crew change occurs on any vessel type. A new work period is defined as beginning when the main engines have been shut off for fours hours or longer.
(2) Vessel owner and operator shore power responsibilities. If shore power is selected as a compliance method to have auxiliary power while at dock, vessel owners and operators must install, maintain, and operate equipment on their vessel needed to draw power provided by shore power connections.
(3) If vessel owners or operators require use of harbor craft shore power up to 99 kW, the facility owners/operators must provide available access to power and accessible connection points as outlined in subsection (i)(1).
(i)Facility Infrastructure Requirements.
(1) Facility Owner and Facility Operator Shore Power Requirements.

Facility owners and facility operators are jointly responsible for and must provide land-side shore power infrastructure sufficient to provide all auxiliary power needs, up to 99 kW for each vessel docked at their facilities as needed for vessel owners and operators to comply with the requirements as set forth in subsection (h).

(A) By January 1, 2024, shore power must be made available at facilities pursuant to the following criteria:
1. The requirements of this subsection apply to any facility at which more than 50 commercial harbor craft vessels visit per calendar year.
2. For purposes of this subsection, a vessel visit is a period of time lasting between one and 24 hours where a vessel operates its auxiliary engines while at dock.
3. Facility owners and facility operators are jointly responsible for, and must purchase, install and maintain all infrastructure needed to support vessel operator shore power requirements in subsection (h)(3).
a. A facility owner or operator that is not able to install the infrastructure required by subsection (i)(1)(B) by January 1, 2024, may request a compliance extension pursuant to subsection (e)(12)(E)1.
(B) Facility owners and operators must install shore power for vessels that require up to 99 kW per vessel berth. Idling and auxiliary operation limits set forth in subsection (h)(1) do not apply to auxiliary engines above 99 kW. Therefore, any vessel shore power needs greater than 99 kW per vessel are not the responsibility of facility owners/operators.
(C) If distributed generation is used to supply shore power, the electricity generated must meet the emissions standards associated with the definition of "distributed generation" in subsection (d).
(D) Facility owners or facility operators whose facilities did not receive 50 vessel visits or more per calendar year in the previous two calendar years at their location and do not have shore power infrastructure for vessels are required to submit an exemption request to the E.O. The request must include records or an estimate of vessel visits for a minimum of the past two calendar years prior to January 1, 2024. The E.O will review and make a decision on the request within 30 days. The facility owners or operators who receive approval for an exemption must keep records of the number of vessel visits in each calendar year and records must be made available upon request by CARB. If a facility whose owner or operator has received an exemption receives 50 or more visits in a calendar year, the facility owner or operator must provide shore power by January 1 of the year that is between 12 and 24 months after the facility allows more than 50 visits in a calendar year. For example, the owner or operator of a facility covered by an exemption in 2025 that allows more than 50 visits in 2025 would need to provide shore power for all vessels visiting the facility by January 1, 2027.
(2) Facility Owner and Facility Operator ZEAT Infrastructure Requirements.

The requirements of this subsection apply to any facility at which ZEAT vessels dock or moor.

(A) Facilities at which ZEAT vessels dock or moor must allow the installation of charging or fueling infrastructure needed to power such ZEAT vessels.
(B) Facility owners and facility operators are jointly responsible for cooperating with vessel owners/operators to allow for surveying, permitting, construction, installation, and maintenance of the necessary charging or fueling infrastructure required to power ZEAT vessels.
(3) Vessel Owners/Operators ZEAT Infrastructure Requirements.
(A) ZEAT vessel owners/operators own and are responsible for purchasing, installing, and maintaining ZEAT infrastructure.
(j)Facility Recordkeeping and Reporting Requirements.
(1) Facility owners or facility operators shall provide a list of all vessel tenants that have use agreements to rent or lease a slip or dock, berth, or moor, for seven (7) days or longer per month at the reporting facility; or, any number of visits if the facility is a marine oil terminal. This list of vessel tenants must be reported to CARB no later than July 1, 2023, and every year by July 1 thereafter, follow the procedures as set forth in subsection (u), and contain the following information:
(A) Facility Information.
1. Applicable facility name;
2. Applicable facility address;

(C) Vessel owner/operator information including:
1. Company name;
2. Company mailing address;
3. Primary contact;
4. Vessel owner/operator primary phone number; and
5. Vessel owner/operator e-mail address.
(D) Start date of vessel and facility use agreement.
(E) Dock, berth or slip location or number at facility.
(F) If applicable, the end date of a use agreement indicating when a vessel has left the facility.
(G) If the facility does not provide shore power to all harbor craft visiting the facility, and fewer than 50 vessels visited the facility in the previous calendar year, the number of visits that occurred in the previous calendar year.
(2) Facilities with land-side infrastructure to support the use of shore power for vessels while at dock must report the following additional information by January 1, 2024, or within 30 days of infrastructure completion if built after January 1, 2024, and reporting shall be performed according to the procedures as set forth in subsection (u):
(A) Infrastructure type, manufacturer, serial number, and installation date;
(B) Equipment type supported, number of vessels supported, and number of plugs; and
(C) Amperage and voltage for each connection.
(3) Beginning January 1, 2023, any person subject to this subsection shall maintain daily records in English, which must contain the following information for at least three years following the date when the records were made, and be supplied to the E.O. within 30 days of a request from CARB staff:
(A) Date, local time, and position (e.g., slip number) for each vessel tenant, and if applicable, the date of vacancy for each vessel tenant.
(k)Opacity Testing and Emission Control Repair Requirements.

This subsection applies to all main propulsion and auxiliary engines operating on all vessels (including commercial fishing vessels), and low-use engines regardless of engine model year, engine tier level, or compliance date. Applicable opacity limits as set forth in subsection (k)(2) must be met whenever the test procedure is administered.

(1) Test Procedure and Repair Requirements.

Opacity testing shall be performed, and opacity must be measured and evaluated, using Society of Automotive Engineers "Surface Vehicle Recommended Practice, Snap Acceleration Smoke Test Procedure for Heavy-Duty Powered Vehicles" (SAE J1667, February 1996), which is incorporated herein by reference.

(A) For purposes of this subsection, smoke opacity shall be measured at a location in the engine exhaust stream after the DPF (if installed) but before the point/location of any seawater injection into exhaust, utilizing either a full- or partial-flow opacity meter.
(B) The following test sequence shall be used for adapting the SAE J1667 test procedure to main propulsion engines:
1. Transit vessel to a safe location in open waters.
2. Stop vessel, clutch-in with engines at idle.
3. Transition controls from idle to full throttle within 2 seconds.
4. Record opacity measurement for 15 seconds or until engines reach full power, whichever is longer.
5. Repeat test procedure five more times.
6. Final opacity measurement will be the average of the 0.5-second maximum of the last three accelerations.
(C) Individuals conducting opacity tests must have completed training and obtained certification on the proper administration of SAE J1667 from the California Council on Diesel Education and Technology (CCDET). The E.O. may approve or offer alternative training courses that satisfy this requirement.
(D) If it can be demonstrated that complying with the requirements of subsection (k)(1) is not feasible due to a safety concern or the engine configuration, then an alternative compliance method may be used if approved by the E.O. In approving a request for use of an alternative method, the E.O. shall consider whether the owner/operator is able to demonstrate that the alternative method will be able to detect increases in soot accumulation rates in the aftertreatment control device, and whether the owner or operator is able to demonstrate that they will be able to provide necessary maintenance and repair.
(E) If a Category 2 or Category 3 engine does not meet opacity limits as set forth in subsection (k)(2), a letter or attestation demonstrating that the engine is in proper operating condition may be considered as an alternative method of compliance with opacity requirements if approved by the E.O. If the letter or attestation is provided by a third-party SAE-certified technician or OEM engine factory-, distributor-, or dealership-certified technician and demonstrates that the engine is in proper operating condition, the E.O. will approve the letter or attestation as an alternative compliance method.
(F) CARB may perform confirmatory opacity testing in the field or audit opacity test records at any time. Additionally, upon having information that an engine may be operating with emission control malfunctions, the E.O. can request that the vessel owner or operator provide to the E.O. an engine or emission control system inspection report from a factory-certified engine or emission control system dealer/distributor within 30 days. The engine or emission control system inspection report must contain all of the information specified in subsection (m)(18) and a summary of an inspection conducted by a factory-certified technician of the make and model of the engines and any emission control devices or systems installed on the vessel, the technician's assessment of whether the engines and emission control devices or systems are within engine and emission control device system mechanical specifications and operational limits, and identification of observable mechanical or operational defects. The owner/operator is responsible for performing any corrective action and reporting to CARB within 30 days of receiving an engine or emission control system inspection.
(G) Swing engines are not subject to subsection (k) when maintained at a dockside location, but are subject to subsection (k) once installed into a vessel.
(2) Opacity Limits for Main Propulsion and Auxiliary Engines.

No engine shall exceed the smoke opacity levels provided below in accordance with this subsection.

(A) Exhaust from engines meeting Tier 3 + DPF or Tier 4 + DPF performance standards shall not exceed five percent smoke opacity.
(B) Exhaust from engines without DPFs shall not exceed 40 percent smoke opacity.
(3) Biennial Testing Requirements for Main Propulsion Engines.
(A) By March 31, 2024, a vessel owner/operator subject to this subsection shall perform opacity testing and report the test results to CARB biennially (every two years). Opacity testing must be performed on each main propulsion engine, and results reported to CARB, once every two-year period ending March 31 of each even-numbered calendar year (i.e. 2024, 2026, 2028, etcetera). For example, opacity test results that must be reported to CARB by March 31, 2026 need to have been performed on the engines between April 1, 2024 and March 31, 2026.
(B) Engines with model year 2020 or newer model year engines are exempt from biennial testing in this subsection (k)(3) until the calendar year that is four years after the model year of the engine. For example, a 2021 model year engine is exempt until 2025, and the first opacity test of the engine must be performed and reported to CARB by March 31, 2026.
(C) If any vessel(s) coming from outside of California will be in RCW for more than 30 consecutive days, engines are newly installed on a vessel (such as a newly acquired engine or a swing engine), or a vessel has been out of service and in dry-dock, opacity testing must be performed and reported on all applicable engines within 30 days of operating within RCW, unless the engine meets the criteria of subsection (k)(3)(B) or has been tested and met opacity limits within the last two years. If the vessel remains in RCW, the test results would satisfy opacity testing requirements required by March 31 of the next even-numbered calendar year.
(D) If the opacity test results exceed the applicable opacity limits as set forth in subsection (k)(2), the engine, DPF, or other emission control system shall be repaired and retested within 30 calendar days from the date of the failed opacity test or the engine shall be taken out of service. The records of opacity testing and repair must be recorded as specified in subsection (m)(18). A post-repair opacity test shall be performed to determine if the measured opacity is within the requirements in subsection (k)(2). The engine may be returned to service if the post-repair opacity meets the opacity limits in subsection (k)(2).
(E) If the post-repair opacity exceeds the applicable opacity limits in subsection (k)(2), the engine shall remain out of service. The engine may be returned to service if it can be repaired so that the post-repair opacity meets opacity limits in subsection (k)(2). The records of opacity testing and repair must be maintained as specified in subsection (m)(18).
(4) Opacity Compliance Requirements for Auxiliary Engines.
(A) Auxiliary engines are subject to meeting the opacity limits as set forth in subsection (k)(2), but are not subject to biennial testing requirements.
(B) If auxiliary engines do not meet opacity limits, the vessel owner/operator has 30 days to repair the engine, demonstrate it meets applicable opacity limits, and notify CARB of the repair and subsequent testing results. Opacity of exhaust from auxiliary engines must be measured using Test Method 9--Visual Determination of the Opacity of Emissions from Stationary Sources as described in 40 CFR Part 60 , Appendix A-4 as it existed on September 26, 2022, which is incorporated herein by reference. Auxiliary engines that do not meet opacity limits must be taken out of service within 30 days from initially not meeting opacity limits.
(l) Compliance Fee Requirements.

This subsection applies to owners or operators of all commercial harbor craft subject to this subsection, except for commercial fishing vessels:

(1) Fees are assessed based on the number of main engines and number of vessels of the most up-to-date information reported to CARB as of March 31 of each calendar year; no fees are assessed for auxiliary engines operating on harbor craft.
(2) The E.O. shall assess and collect reasonable fees for deposit in the Certification and Compliance Fund to recover the estimated costs of the E.O. administering this subsection.
(3) Fees shall be due and payable to CARB by September 1 of each calendar year beginning in 2023.
(4) Fees are nonrefundable.
(5) Owners or operators of vessels must submit fees to CARB in accordance with the fee schedule, including late fees as applicable, in Table 23. A "late fee" is required to be paid if CARB does not receive the annual fee payment by September 1. The late annual fees and late fee must be paid by December 31 of the same calendar year fees are due.

Table 23. Annual Fees for Owners or Operators of Regulated In-Use Vessels

CategoryFee Amount
Per vessel, for single-vessel fleets$364
Per vessel, for all other fleets$486
Per main engine, for single-vessel fleets$297
Per main engine, for all other fleets$396
Per main engine, if complying by low-use exception as set forth in subsection (e)(14)$594
Late fee, per vessel$130
Late fee, per engine$86

For example, for a vessel in a multi-vessel fleet with two main engines, the vessel owner or operator shall pay a total of $486 + ($396 x 2) = $1,278 per year for that one vessel. If the operator fails to pay this amount by September 1st, an additional $130 + ($86 x 2) = $302 late fee would be required for this vessel. For a fleet with one vessel only, with three main engines total, one of which is a low-use engine, the vessel owner or operator shall pay a total of $364 + ($297x2) + $594 = $1,552 per year. If the operator fails to pay this amount by September 1st, an additional $130 + ($86 x 3) = $388 late fee would be required for this vessel.

(m)Recordkeeping Requirements.

Beginning January 1, 2009, the owner or operator of a harbor craft must maintain the records specified in this subsection on the vessel or at the vessel's homebase for the life of each engine subject to this section, including fleet swing engines and marinized land-based engines.

8. Hours and minutes fished on the days that fishing occurs.
(D) Number of passenger-days by calendar year. A "passenger-day" equals eight hours of fishing activity by one angler, or shorter periods of fishing activity by multiple anglers adding up to eight hours. For example, a four-hour trip with 20 anglers would equal 10 passenger-days; a six-hour trip with 20 anglers would equal 15 passenger-days; and a three-day trip (eight hours of fishing activity per day) with 20 anglers would equal 60 passenger-days. Trip duration must be calculated to the nearest one-hour increment, and passenger-days must be recorded to the nearest tenth of a day. For example, a trip including 11 anglers lasting four hours and 20 minutes would equal 5.5 passenger-days (11 anglers x 4 hours/8 hours). Standard rounding convention must be used in calculating and recording passenger-days (i.e., fractional passenger-days less than x.x5 are not increased (so 1.54 rounds to 1.5), fractional passenger-days equal to or greater than x.x6 are rounded to the next fraction (so 1.56 rounds to 1.6), and fractional passenger-days equal to x.x5 are rounded either up or down to make the fraction even (so 1.55 rounds to 1.6 but 1.85 rounds to 1.8)).
