Current through December 26, 2024
Section 250-RICR-150-10-1.32 - Storm Water Discharges
A. Permit Requirement
1. The following discharges composed entirely of storm water shall be required to obtain a RIPDES permit:
a. A discharge with respect to which a permit has been issued prior to February 4, 1987;
b. A discharge associated with industrial activity;
c. A discharge from a large municipal separate storm sewer system;
d. A discharge from a medium municipal separate storm sewer system;
e. A discharge from a small municipal separate storm sewer system;
f. A discharge associated with small construction activity;
g. A discharge which the Department, or in States with approved NPDES programs, either the Department or the EPA Regional Administrator, determines to contribute to a violation of a water quality standard or is a significant contributor of pollutants to waters of the United States. This designation may include a discharge from any conveyance or system of conveyances used for collecting and conveying storm water runoff or a system of discharges from municipal separate storm sewers, except for those discharges from conveyances which do not require a permit under § 1.32(A)(2) of this Part or agricultural storm water runoff which is exempted from the definition of point source at § 1.4(A)(78) of this Part. The Department may designate discharges from municipal separate storm sewers on a system-wide basis. In making this determination the Department may consider the following factors:
(1) The location of the discharge with respect to waters of the State as defined in § 1.4 of this Part.
(2) The size of the discharge;
(3) The quantity and nature of the pollutants discharged to waters of the State; and
(4) Other relevant factors.
h. A discharge for which the Department or the EPA Regional Administrator determines that storm water controls are necessary to ensure implementation of wasteload allocations that are part of "total maximum daily loads" (TMDLs) that address the pollutant(s) that has been identified as the cause of impairment of the water body.
2. Mining and oil and gas exploration. The Department may not require a permit for discharges of storm water runoff from mining operations or oil and gas exploration, production, processing or treatment operations or transmission facilities, composed entirely of flows which are from conveyances or systems of conveyances (including but not limited to pipes, conduits, ditches, and channels) used for collecting and conveying precipitation runoff and which are not contaminated by contact with or that has not come into contact with, any overburden, raw material, intermediate products, finished product, byproduct or waste products located on the site of such operations.
3. Municipally owned or operated discharges of storm water associated with industrial activity. For any storm water discharge associated with industrial activity from a facility that is owned or operated by a municipality with a population of less than 100,000 that does not have an effective RIPDES permit authorizing the discharge other than an airport, power plant, or uncontrolled sanitary landfill, a permit application must be submitted by March 10, 2003.
4. Large and medium municipal separate storm sewer systems.
a. Permits must be obtained for all discharges from large and medium municipal separate storm sewer systems. However, the owner or operator of a municipal separate storm sewer system may petition the Department to reduce the Census estimates of the population served by such separate system to account for storm water discharged to combined sewers as defined by 40 C.F.R. § 35.2005(b)(11), incorporated above at § 1.3(B) of this Part, that is treated in a publicly owned treatment works. In municipalities in which combined sewers are operated, the Census estimates of population may be reduced proportional to the fraction, based on estimated lengths, of the length of combined sewers over the sum of the length of combined sewers and municipal separate storm sewers where an applicant has submitted the RIPDES permit number associated with each discharge point and a map indicating areas served by combined sewers and the location of any combined sewer overflow discharge point.
b. The Department may either issue one system-wide permit covering all discharges from municipal separate storm sewers within a large or medium municipal storm sewer system or issue distinct permits for appropriate categories of discharges within a large or medium municipal separate storm sewer system including, but not limited to: all discharges owned or operated by the same municipality; located within the same jurisdiction; all discharges within a system that discharge to the same watershed; discharges within a system that are similar in nature; or for individual discharges from municipal separate storm sewers within the system.
c. The operator of a discharge from a municipal separate storm sewer which is part of a large or medium municipal separate storm sewer system must either:
(1) Participate in a permit application (to be a permittee or a co-permittee) with one or more other operators of discharges from the large or medium municipal storm sewer system which covers all, or a portion of all, discharges from the municipal separate storm sewer system;
(2) Submit a distinct permit application which only covers discharges from the municipal separate storm sewers for which the operator is responsible; or
(3) A regional authority may be responsible for submitting a permit application under the following guidelines:
(AA) The regional authority together with co-applicants shall have authority over a storm water management program that is in existence, or shall be in existence at the time Part 1 of the application is due;
(BB) The permit applicant or co-applicants shall establish their ability to make a timely submission of Part 1 and Part 2 of the municipal application;
(CC) Each of the operators of municipal separate storm sewers within the systems described in §§ 1.4(A)(53)(a), 1.4(A)(53)(b), and 1.4(A)(53)(c) of this Part, that are under the purview of the designated regional authority, shall comply with the application requirements of § 1.32(A)(4)(d) of this Part.
d. One permit application may be submitted for all or a portion of all municipal separate storm sewers within adjacent or interconnected large or medium municipal separate storm sewer systems. The Department may issue one system-wide permit covering all, or a portion of all municipal separate storm sewers in adjacent or interconnected large or medium municipal separate storm sewer systems.
e. Permits for all or a portion of all discharges from large or medium municipal separate storm sewer systems that are issued on a system-wide, jurisdiction-wide, watershed or other basis may specify different conditions relating to different discharges covered by the permit, including different management programs for different drainage areas which contribute storm water to the system.
f. Co-permittees need only comply with permit conditions relating to discharges from the municipal separate storm sewers for which they are operators.
5. Small municipal storm sewer systems
a. The following discharges from small municipal separate storm sewer systems must obtain permits:
(1) The small MS4, excluding systems operated by federal and State government, is located in an urbanized area as defined in § 1.4 of this Part, unless a waiver is granted in accordance to § 1.32(G) of this Part. If any portion of the small MS4 is not entirely located within an urbanized area, the portion that is within the urbanized area is regulated (see § 1.72 of this Part).
(2) The small MS4, excluding systems operated by federal and State government, is located in a densely populated area as defined in § 1.4 of this Part, unless a waiver is granted in accordance to § 1.32(G) of this Part. If any portion of the small MS4 is not entirely located within a densely populated area, the portion that is within the densely populated area is regulated (see § 1.73 of this Part).
(3) The small MS4, operated by federal or State government serves a facility with an average daily population of equal to or greater than 1,000.
(4) Any portion of the small MS4 operated by the Rhode Island Department of Transportation is located in an urbanized area as defined in § 1.4 of this Part or a densely populated area, as defined in § 1.4 of this Part, or serves a divided highway regardless of its location, only these portions are regulated (see § 1.73 of this Part).
(5) The Department has determined that the system is contributing substantially to the pollutant loadings of a physically-interconnected regulated MS4.
(6) The Department has determined that the information required for granting a waiver has substantially changed or upon consideration of a petition to review a waiver when the petitioner provides evidence that the information required for granting the waiver has substantially changed in accordance with § 1.32(G) of this Part.
(7) On or after March 10, 2008, the small MS4 discharges to any Special Resource Protection Waters (SPRWs), Outstanding National Resource Waters (ONRWs), or impaired water bodies within its jurisdiction and a waiver has not been granted in accordance to § 1.32(G) of this Part.
(8) The Department has determined that the small MS4 discharge contributes to a violation of a water quality standard or is a significant contributor of pollutants to waters of the State in accordance with § 1.32 of this Part.
(9) The Department has determined that storm water controls are needed for the small MS4 discharge based on wasteload allocations that are part of "total maximum daily loads" (TMDLs) that address the pollutant(s) of concern in accordance with § 1.32 of this Part.
(10) The Department has designated the small MS4 based on a petition pursuant to § 1.32 of this Part.
b. The operator of a small MS4 may rely on another entity to satisfy the permit obligations to implement a minimum control measure as follows:
(1) The other entity, in fact, implements the minimum control measure;
(2) The particular control measure, or component thereof, is at least as stringent as the corresponding permit requirements; and
(3) The other entity agrees to implement the control measure on the behalf of the operator of the regulated small MS4;
(4) If the operator of the small MS4 is relying on another governmental entity regulated under § 1.32 of this Part to satisfy all of the permit obligations, including the obligation to file periodic reports required in § 1.17(J) of this Part, the operator of the small MS4 must note that fact in the Notice of Intent (NOI), but the operator is not required to file the periodic reports.
(5) The operator of the small MS4 remains responsible for compliance with the permit requirements if the entity fails to implement the control measure or component thereof.
(6) The Department may recognize, either in the individual permit or in a general permit, that the Department or another governmental entity is responsible under a RIPDES Permit for implementing one or more of the minimum control measures for the small MS4. In such cases, the operator is not required to include the minimum control measure implemented by that entity as required by § 1.32 of this Part.
(7) If the governmental entity identified in § 1.32(A)(5)(a) ((6)) of this Part fails to implement a minimum control measure, the permit issued in accordance with § 1.32(E) of this Part may be reopened and modified in accordance with § 1.24 of this Part to include the requirement to implement a minimum control measure.
c. Operators of regulated small MS4s shall fully implement the Storm Water Management Program Plan as defined in § 1.32(E)(3) of this Part within the first permit term of five (5) years.
d. The operator of the small MS4 must comply with other applicable permit requirements, standards and conditions established in the individual or general permit, developed consistent with the provisions of §§ 1.15 through 1.21 of this Part, as appropriate.
e. The operator of the small MS4 must comply with any more stringent effluent limitations of the permit, including permit requirements that modify, or are in addition to the minimum control measures in § 1.32(E)(3)(b) of this Part based on an approved total maximum daily load (TMDL) or equivalent analysis. The Department may include such more stringent limitations based on a TMDL or equivalent analysis that determines such limitations are needed to protect water quality.
f. If an existing qualifying local program requires the operator of the small MS4 to implement one or more of the minimum control measures of § 1.32(E)(3)(b) of this Part, the Department may include conditions in the RIPDES permit that direct the operator of the small MS4 to follow that qualifying program's requirements rather than the requirements of § 1.32(E)(3) of this Part. A qualifying local program is a local or State storm water management program that meets the requirements of § 1.16(A)(10) of this Part.
6. Discharges through large and medium municipal separate storm sewer systems. In addition to meeting the requirements of § 1.32(D) of this Part, an operator of a storm water discharge associated with industrial activity which discharges through a large or medium municipal separate storm sewer system shall submit, to the operator of the municipal separate storm sewer system receiving the discharge thirty (30) days after the effective date of these Regulations, or for a new discharge, 180 days prior to commencing such discharge: the name of the facility; a contact person and phone number; the location of the discharge; a description, including Standard Industrial Classification, which best reflects the principal products or services provided by each facility; and any existing RIPDES permit number.
7. Other municipal separate storm sewers. The Department may issue permits for municipal separate storm sewers that are designated under §§ 1.32(A)(1)(g) and (h) of this Part on a system-wide basis, jurisdiction-wide basis, watershed basis or other appropriate basis, or may issue permits for individual discharges.
8. Non-municipal separate storm sewers. For storm water discharges associated with industrial activity from point sources which discharge through a non-municipal or non-publicly owned separate storm sewer system, the Department, in his or her discretion, may issue: a single RIPDES permit to the operator of the portion of the system that discharges into waters of the State, with each contributing discharger listed as a co-permittee or; individual permits to each discharger of storm water associated with industrial activity through the non-municipal conveyance system.
a. All storm water discharges associated with industrial activity that discharge through a storm water discharge system that is not a municipal separate storm sewer must be covered by an individual permit, or a permit issued to the operator of the portion of the system that discharges to waters of the State, with each discharger to the non-municipal conveyance a co-permittee to that permit.
b. Where there is more than one operator of a single system of such conveyances, all operators of storm water discharges associated with industrial activity must submit applications.
c. Any permit covering more than one operator shall identify the effluent limitations, or other permit conditions, if any, that apply to each operator.
9. Combined sewer systems. Conveyances that discharge storm water runoff combined with municipal sewage are point sources that must obtain RIPDES permits in accordance with the procedures § 1.11 of this Part and are not subject to the provisions of this section.
10. Effect on Eligibility for Federal Funding. Whether a discharge from a municipal separate storm sewer is or is not subject to regulation under this section shall have no bearing on whether the owner or operator of the discharge is eligible for funding under 33 U.S.C. Subchapter II, Subchapter III or Subchapter VI (Title II, Title III or Title VI of the Clean Water Act). See 40 C.F.R. § 35 Subpart I (incorporated above at § 1.3(B) of this Part).

Field screening points shall be either major outfalls or other outfall points (or any other point of access such as manholes) randomly located throughout the storm sewer system by placing a grid over a drainage system map and identifying those cells of the grid which contain a segment of the storm sewer system or major outfall. The field screening points shall be established using the following guidelines and criteria:
(AA) A grid system consisting of perpendicular north-south and east-west lines spaced 1/4 mile apart shall be overlayed on a map of the municipal storm sewer system, creating a series of cells;
(BB) All cells that contain a segment of the storm sewer system shall be identified; one field screening point shall be selected in each cell; major outfalls may be used as field screening points;
(CC) Field screening points should be located downstream of any sources of suspected illegal or illicit activity;
(DD) Field screening points shall be located to the degree practicable at the farthest manhole or other accessible location downstream in the system, within each cell; however, safety of personnel and accessibility of the location should be considered in making this determination;

The owner or operator of a municipal separate storm sewer system may petition the Department to reduce the Census estimates of the population served by such separate system to account for storm water discharged to combined sewers as defined by 40 C.F.R. § 35.2005(b)(11), incorporated above at § 1.3(B) of this Part, that is treated in a publicly owned treatment works. In municipalities in which combined sewers are operated, the Census estimates of population may be reduced proportional to the fraction, based on estimated lengths, of the length of combined sewers over the sum of the length of combined sewers and municipal separate storm sewers where an applicant has submitted the RIPDES permit number associated with each discharge point and a map indicating areas served by combined sewers and the location of any combined sewer overflow discharge point.
4. Any person may petition the Department for the designation of a large, medium or small municipal separate storm sewer system as defined by §§ 1.4(A)(53)(d), 1.4(A)(59)(d), or 1.4(A)(105) of this Part. Final determination on any petition will be made in accordance to § 1.32(G)(8) of this Part.
5. The Department may waive the requirement to obtain a permit for small municipal separate storm sewer systems under the following circumstances:
a. The small MS4 is located within a jurisdiction with only urbanized areas that contain a total population of less than 1,000 or a jurisdiction with only densely populated areas (See §§ 1.72 and 1.73 of this Part), and the MS4 meets the following criteria:
(1) The small MS4 is not contributing substantially to the pollutant loadings of a physically interconnected regulated MS4;
(2) The small MS4 does not discharge to an impaired water body, within the urbanized area or densely populated area;
(3) If the small MS4 does discharge to an impaired water body within the urbanized area or densely populated area, the operator of the small MS4 has demonstrated that it does not discharge any pollutants that have been identified as the cause of impairment;
(4) If the small MS4 discharges any pollutant(s) that have been identified as a cause of impairment, to an impaired water body within the urbanized area or densely populated area, then it must be demonstrated that storm water controls are not needed based on wasteload allocations that are part of an EPA approved or established TMDL that addresses the pollutant(s) causing the impairment.
b. The small MS4 is located in a jurisdiction with urbanized areas or both urbanized areas and densely populated areas that contain a total population greater than or equal to 1,000 but less than 10,000 (See §§ 1.72 and 1.73 of this Part), and the MS4 meets all of the following criteria:
(1) The Department has evaluated all waters of the State, including small streams, tributaries, lakes, and ponds, that receive a discharge from the small MS4, throughout the jurisdiction;
(2) For all such waters, the Department has determined that storm water controls are not needed based on wasteload allocations that are part of an EPA approved or established TMDL that addresses the pollutant(s) of concern or, if a TMDL has not been developed or approved, an equivalent analysis that determines sources and allocation for the pollutant(s) of concern;
(3) For the purpose of this paragraph, the pollutant(s) of concern include biochemical oxygen demand (BOD), sediment or a parameter that addresses sediment (such as total suspended solids, turbidity or siltation), pathogens, oil and grease, and any pollutant that has been identified as a cause of impairment of any water body that will receive a discharge from the MS4, throughout the jurisdiction; and
(4) The operator of the MS4 has demonstrated to the satisfaction of the Department that future discharges from the MS4 do not have the potential to result in exceedances of water quality standards, including impairment of designated uses, or other significant water quality impacts, including habitat and biological impacts.
c. On or after March 2008, the operator of a small MS4, located outside urbanized areas and densely populated areas (See §§ 1.72 and 1.73 of this Part), or previously waived in accordance with §§ 1.32(G)(5)(a) and 1.32(G)(5)(b) of this Part that discharges to Special Resource Protection Waters (SRPWs), Outstanding National Resource Waters (ONRWs) or impaired waters, will be required to obtain a permit, unless the operator has demonstrated effective protection of water quality to the satisfaction of the Department by meeting the following criteria:
(1) The operator has documented that the Storm Water Management Program Plan as defined in § 1.32(E) of this Part is applied to all Special Resource Protection Waters (SRPWs), Outstanding National Resource Waters (ONRWs), or impaired water bodies that receive a discharge from the small MS4; or
(2) If the small MS4 discharges to Special Resource Protection Waters (SPRWs), Outstanding National Resource Waters (ONRWs), or impaired water bodies then it must be demonstrated that existing and future discharges from the MS4 do not have the potential to result in water quality impacts including habitat and biological impacts; and
(3) If the small MS4 was previously waived in accordance to §§ 1.32(G)(5)(a) and 1.32(G)(5)(b) of this Part the Department must determine that those criteria for granting the waiver continue to be met.
6. Any person may petition the Department to review a waiver when the petitioner provides evidence that the information required for granting the waiver have changed.
7. The Department will periodically review any waivers granted in accordance to § 1.32(G)(5) of this Part to determine whether any of the information for granting the waiver has changed. At a minimum such review will be conducted once every five (5) years.
8. The Department shall make a final determination on any petition received under this section within a reasonable period of time after receiving the petition with the exception of petitions to designate a small MS4 in which case the Department shall make a final determination on the petition within one hundred eighty (180) days after its receipt. Where the Department does not make a determination for a petition in accordance to these deadlines, EPA may make a determination on the petition. For any storm water discharge from a small MS4 that the Department has designated, a permit application shall be submitted to the Department within one hundred eighty (180) days of notice.
H. Conditional exclusion for "no exposure" of industrial activities and materials to storm water. Discharges composed entirely of storm water are not storm water discharges associated with industrial activity if there is "no exposure" of industrial materials and activities to rain, snow, snowmelt and/or runoff, and the discharger satisfies the conditions in §§ 1.32(H)(1) through 1.32(H)(4) of this Part. "No exposure", for purposes of this section, means that all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt and/or runoff. Industrial materials or activities include, but are not limited to, material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product.
1. Qualification. To qualify for this exclusion, the operator of the discharge must:
a. Provide a storm resistant shelter to protect industrial materials and activities from exposure to rain, snow, snowmelt, and runoff;
b. Complete and sign (according to § 1.12 of this Part) a certification, in accordance to § 1.32(H)(4) of this Part that there are no discharges of storm water contaminated by exposure to industrial materials and activities from the entire facility, except as provided in § 1.32(H)(2) of this Part;
c. Submit the signed certification to the Department once every five years;
d. Allow the Department to inspect the facility to determine compliance with the "no exposure" conditions;
e. Allow the Department to make any "no exposure" inspection reports available to the public upon request; and
f. For facilities that discharge through an MS4, upon request, submit a copy of the certification of "no exposure" to the MS4 operator, as well as allow inspection and public reporting by the MS4 operator.
2. Industrial materials and activities not requiring storm resistant shelter. To qualify for this exclusion, storm resistant shelter is not required for:
a. Drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak ("Sealed", for the purpose of this section, means banded or otherwise secured and without operational taps or valves);
b. Adequately maintained vehicles used in material handling; and
c. Final products, other than products that would be mobilized in storm water discharge (e.g., rock salt).
3. Limitations.
a. Storm water discharges from construction activities identified in as defined in §§ 1.4(A)(111)(j) and 1.4(A)(112) of this Part are not eligible for this conditional exclusion.
b. This conditional exclusion from the requirement for a RIPDES permit is available on a facility-wide basis only, not for individual outfalls. If a facility has some discharges of storm water that would otherwise be "no exposure" discharges, individual permit requirements should be adjusted accordingly.
c. If circumstances change and industrial materials or activities become exposed to rain, snow, snowmelt, and/or runoff, the conditions for this exclusion no longer apply. In such cases, the discharger becomes subject to enforcement for un-permitted discharges. Any conditionally exempt discharger who anticipates changes in circumstances should apply for and obtain permit authorization prior to the change of circumstances.
d. Notwithstanding the provisions of this paragraph, the Department retains the authority to require permit authorization (and deny this exclusion) upon making a determination that the discharge causes, has a reasonable potential to cause, or contributes to an instream excursion above an applicable water quality standard, including designated uses.
e. The Department retains the authority to require permit authorization (and deny this exclusion) on a case-by-case basis, based on the information provided in § 1.32(H)(4) of this Part or upon making a determination that the materials or activities listed in § 1.32(H)(4)(c) of this Part are or have been exposed to precipitation.
4. Certification. The operator of a discharge seeking a conditional exclusion must submit to the Department a no exposure certification that contains the following information, at a minimum, to aid the Department in determining if the facility qualifies for the no exposure exclusion:
a. The legal name, address and phone number of the discharger (see § 1.8(C) of this Part);
b. The facility name and address, the county name and the latitude and longitude where the facility is located;
c. The certification must indicate that none of the following materials or activities are, or will be in the foreseeable future, exposed to precipitation:
(1) Using, storing or cleaning industrial machinery or equipment, and areas where residuals from using, storing or cleaning industrial machinery or equipment remain and are exposed to storm water;
(2) Materials or residuals on the ground or in storm water inlets from spills/leaks;
(3) Materials or products from past industrial activity;
(4) Material handling equipment (except adequately maintained vehicles);
(5) Materials or products during loading/unloading or transport activities;
(6) Materials or products stored outdoors (except final products intended for outside use, e.g., new cars, where exposure to storm water does not result in the discharge of pollutant);
(7) Materials contained in open, deteriorated or leaking storage drums, barrels, tanks, and similar containers;
(8) Materials or products handled/stored on roads or railways owned or maintained by the discharger;
(9) Waste material (except waste in covered, non-leaking containers, e.g., dumpsters);
(10) Application or disposal of process wastewater (unless otherwise permitted); and
(11) Particulate matter or visible deposits of residuals from roof stack/vents not otherwise regulated, i.e., under an air quality control permit, and evident in the storm water outflow;
d. All "no exposure" certifications must include the following certification statement, and be signed in accordance with the signatory requirements of § 1.12 of this Part): "I certify under penalty of law that I have read and understand the eligibility requirements for claiming a condition of "no exposure" and obtaining an exclusion from RIPDES storm water permitting; and that there are no discharges of storm water contaminated by exposure to industrial activities or materials from the industrial facility identified in this document (except as allowed under § 1.32(H)(2) of this Part. I understand that I am obligated to submit a no exposure certification form once every five (5) years to the Department and, if requested, to the operator of the local MS4 into which this facility discharges (where applicable), I understand that I must allow the Department, or MS4 operator where the discharge is into the local MS4, to perform inspections to confirm the condition of no exposure and to make such inspection reports publicly available upon request. I understand that I must obtain coverage under a RIPDES permit prior to any point source discharge of storm water from the facility. I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based upon my inquiry of the person or persons who manage the system, or those persons directly involved in gathering the information, the information submitted is to the best of my knowledge and belief true, accurate and complete. I am aware there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."
e. Any other additional information that the Department deems is necessary to make a determination.
