Current through Register Vol. 50, No. 9, September 20, 2024

Section IX-2515 - General Permits

A. Coverage. The state administrative authority may issue a general permit in accordance with the following.

1. Area. The general permit shall be written to cover one or more categories or subcategories of discharges or sludge use or disposal practices or facilities described in the permit under Subparagraph A.2.b of this Section, except those covered by individual permits, within a geographic area. The area shall correspond to existing geographic or political boundaries, such as:

a. designated planning areas under Sections 208 of the CWA;

b. sewer districts or sewer authorities;

c. city, parish, or state political boundaries;

d. state highway systems;

e. standard metropolitan statistical areas as defined by the U.S. Office of Management and Budget;

f. urbanized areas as designated by the Bureau of the Census according to criteria in 30 FR 15202 (May 1, 1974); or

g. any other appropriate division or combination of boundaries.

2. Sources. The general permit may be written to regulate one or more categories or subcategories of discharges, sludge use, disposal practices, or facilities, within the area described in Paragraph A.1 of this Section, where the sources within a covered subcategory of discharges are either:

a. storm water point sources; or

b. one or more categories or subcategories of point sources other than storm water point sources, or one or more categories or subcategories of treatment works treating domestic sewage, if the sources or treatment works treating domestic sewage within each category or subcategory all:

i. involve the same or substantially similar types of operations;

ii. discharge the same types of wastes or engage in the same types of sludge use or disposal practices;

iii. require the same effluent limitation or operating conditions, or standards for sewage sludge use or disposal;

iv. require the same or similar monitoring; and

v. in the opinion of the state administrative authority, are more appropriately controlled under a general permit than under individual permits.

3. Water Quality-Based Limits. Where sources within a specific category or subcategory of dischargers are subject to water quality-based limits imposed in accordance with LAC 33:IX.2707, the sources in that specific category or subcategory shall be subject to the same water quality-based effluent limitations.

4. Other Requirements

a. The general permit must clearly identify the applicable conditions for each category or subcategory of dischargers or treatment works treating domestic sewage covered by the permit.

b. The general permit may exclude specified sources or areas from coverage.

B. Administration

1. In General. General permits may be issued, modified, revoked and reissued, or terminated in accordance with applicable requirements of 40 CFR Part 124 or corresponding state regulations. Special procedures for issuance are found at 40 CFR 123.44 for states.

2. Authorization to Discharge, or Authorization to Engage in Sludge Use and Disposal Practices

a. Except as provided in Subparagraphs B.2.e and f of this Section, dischargers (or treatment works treating domestic sewage) seeking coverage under a general permit shall submit to the Office of Environmental Services a written notice of intent to be covered by the general permit. A discharger (or treatment works treating domestic sewage) who fails to submit a notice of intent in accordance with the terms of the permit is not authorized to discharge, (or in the case of sludge disposal permit, to engage in a sludge use or disposal practice), under the terms of the general permit unless the general permit, in accordance with Subparagraph B.2.e of this Section, contains a provision that a notice of intent is not required or the state administrative authority notifies a discharger (or treatment works treating domestic sewage) that it is covered by a general permit in accordance with Subparagraph B.2.f of this Section. A complete and timely notice of intent (NOI), to be covered in accordance with general permit requirements, fulfills the requirements for permit applications for purposes of LAC 33:IX.2321, 2501, and 2511.

b. The contents of the notice of intent shall be specified in the general permit and shall require the submission of information necessary for adequate program implementation, including at a minimum, the legal name and address of the owner or operator, the facility name and address, type of facility or discharges, and the receiving stream(s). General permits for storm water discharges associated with industrial activity from inactive mining, inactive oil and gas operations, or inactive landfills occurring on federal lands where an operator cannot be identified may contain alternative notice of intent requirements. All notices of intent shall be signed in accordance with LAC 33:IX.2503. Notices of intent for coverage under a general permit for concentrated animal feeding operations must include the information specified in LAC 33:IX.2501.I.1, including a topographic map.

c. General permits shall specify the deadlines for submitting notices of intent to be covered and the date(s) when a discharger is authorized to discharge under the permit.

d. General permits shall specify whether a discharger (or treatment works treating domestic sewage) that has submitted a complete and timely notice of intent to be covered in accordance with the general permit and that is eligible for coverage under the permit, is authorized to discharge, (or in the case of a sludge disposal permit, to engage in a sludge use or disposal practice), in accordance with the permit either upon receipt of the notice of intent by the state administrative authority, after a waiting period specified in the general permit, on a date specified in the general permit, or upon receipt of notification of inclusion by the state administrative authority. Coverage may be terminated or revoked in accordance with LAC 33:IX.2515.B.3.

e. Discharges other than discharges from publicly owned treatment works, combined sewer overflows, municipal separate storm sewer systems, primary industrial facilities, and storm water discharges associated with industrial activity, may, at the discretion of the state administrative authority, be authorized to discharge under a general permit without submitting a notice of intent where the state administrative authority finds that a notice of intent requirement would be inappropriate. In making such a finding, the state administrative authority shall consider: the type of discharge; the expected nature of the discharge; the potential for toxic and conventional pollutants in the discharges; the expected volume of the discharges; other means of identifying discharges covered by the permit; and the estimated number of discharges to be covered by the permit. The state administrative authority shall provide in the public notice of the general permit the reasons for not requiring a notice of intent.

f. The state administrative authority may notify a discharger (or treatment works treating domestic sewage) that it is covered by a general permit, even if the discharger (or treatment works treating domestic sewage) has not submitted a notice of intent to be covered. A discharger (or treatment works treating domestic sewage) so notified may request an individual permit under LAC 33:IX.2515.B.3.c.

g. A CAFO owner or operator may be authorized to discharge under a general permit only in accordance with the process described in LAC 33:IX.2505.H.

h. Small Municipal Separate Storm Sewer Systems (MS4s). For general permits issued under Paragraph B of this Section for small MS4s, the state administrative authority shall establish the terms and conditions necessary to meet the requirements of LAC 33:IX.2523 using one of the two permitting approaches in Clauses i-ii of this Section. The state administrative authority shall indicate in the permit or fact sheet which approach is being used.

i. Comprehensive General Permit. The state administrative authority includes all required permit terms and conditions in the general permit; or

ii. Two-step General Permit. The state administrative authority includes required permit terms and conditions in the general permit applicable to all eligible small MS4s; and during the process of authorizing small MS4s to discharge, establishes additional terms and conditions not included in the general permit to satisfy one or more of the permit requirements in LAC 33:IX.2523 for individual small MS4 operators.

(a) The general permit shall require that any small MS4 operator seeking authorization to discharge under the general permit submit a Notice of Intent (NOI) consistent with LAC 33:IX.2515.B.2.b.

(b) The state administrative authority shall review the NOI submitted by the small MS4 operator to determine whether the information in the NOI is complete and to establish the additional terms and conditions necessary to meet the requirements of LAC 33:IX.2523. The state administrative authority may require the small MS4 operator to submit additional information. The public notice, the process for submitting public comments and hearing requests, and the hearing process, if a request for a hearing is granted, shall follow the procedures applicable to draft permits set forth in LAC 33:IX.315. If the state administrative authority makes a preliminary decision to authorize the small MS4 operator to discharge under the general permit, the state administrative authority shall give the public notice of:

(i) an opportunity to comment and request a public hearing on its proposed authorization and the NOI;

(ii) the proposed additional terms and conditions; and

(iii) the basis for these additional requirements.

(c) Upon authorization for the MS4 to discharge under the general permit, the final additional terms and conditions applicable to the MS4 operator become effective. The state administrative authority shall notify the permittee and inform the public of the decision to authorize the MS4 to discharge under the general permit and of the final additional terms and conditions specific to the MS4.

3. Requiring an Individual Permit

a. The state administrative authority may require any discharger authorized by a general permit to apply for and obtain an individual LPDES permit. Any interested person may petition the state administrative authority to take action under this Paragraph. Cases where an individual LPDES permit may be required include the following:

i. the discharger or treatment works treating domestic sewage is not in compliance with the conditions of the general LPDES permit;

ii. a change has occurred in the availability of demonstrated technology or practices for the control or abatement of pollutants applicable to the point source or treatment works treating domestic sewage;

iii. effluent limitation guidelines are promulgated for point sources covered by the general LPDES permit;

iv. a water quality management plan containing requirements applicable to such point sources is approved;

v. circumstances have changed since the time of the request to be covered so that the discharger is no longer appropriately controlled under the general permit, or either a temporary or permanent reduction or elimination of the authorized discharge is necessary;

vi. standards for sewage sludge use or disposal have been promulgated for the sludge use and disposal practice covered by the general LPDES permit; or

vii. the discharge(s) is a significant contributor of pollutants. In making this determination, the state administrative authority may consider the following factors:

(a). the location of the discharge with respect to waters of the state;

(b). the size of the discharge;

(c). the quantity and nature of the pollutants discharged to waters of the state; and

(d). other relevant factors.

b. For EPA issued general permits only, the EPA regional administrator may require any owner or operator authorized by a general permit to apply for an individual NPDES permit as provided in 40 CFR 122.28(b)(3)(i), only if the owner or operator has been notified in writing that a permit application is required. This notice shall include a brief statement of the reasons for this decision, an application form, a statement setting a time for the owner or operator to file the application, and a statement that on the effective date of the individual NPDES permit the general permit as it applies to the individual permittee shall automatically terminate. The director may grant additional time upon request of the applicant.

c. Any owner or operator authorized by a general permit may request to be excluded from the coverage of the general permit by applying for an individual permit. The owner or operator shall submit an application under LAC 33:IX.2501, with reasons supporting the request, to the director no later than 90 days after the publication by EPA of the general permit in the Federal Register or the publication by a state in accordance with applicable state law. The request shall be processed under 40 CFR Part 124 or applicable state procedures. The request shall be granted by issuing of any individual permit if the reasons cited by the owner or operator are adequate to support the request.

d. When an individual LPDES permit is issued to an owner or operator otherwise subject to a general LPDES permit, the applicability of the general permit to the individual LPDES permittee is automatically terminated on the effective date of the individual permit.

e. A source excluded from a general permit solely because it already has an individual permit may request that the individual permit be revoked, and that it be covered by the general permit. Upon revocation of the individual permit, the general permit shall apply to the source.

C. Offshore Oil and Gas Facilities

1. The EPA regional administrator shall, except as provided below, issue general permits covering discharges from offshore oil and gas exploration and production facilities within the region's jurisdiction. Where the offshore area includes areas, such as areas of biological concern, for which separate permit conditions are required, the EPA regional administrator may issue separate general permits, individual permits, or both. The reason for separate general permits or individual permits shall be set forth in the appropriate fact sheets or statements of basis. Any statement of basis or fact sheet for a draft permit shall include the EPA regional administrator's tentative determination as to whether the permit applies to new sources, new dischargers, or existing sources and the reasons for this determination, and the EPA regional administrator's proposals as to areas of biological concern subject either to separate individual or general permits. For federally leased lands, the general permit area should generally be no less extensive than the lease sale area defined by the Department of the Interior.

2. Any interested person, including any prospective permittee, may petition the EPA regional administrator to issue a general permit. Unless the EPA regional administrator determines under 40 CFR 122.28(c)(1) that no general permit is appropriate, he shall promptly provide a project decision schedule covering the issuance of the general permit or permits for any lease sale area for which the Department of the Interior has published a draft environmental impact statement. The project decision schedule shall meet the requirements of 40 CFR 124.3(g), and shall include a schedule providing for the issuance of the final general permit or permits not later than the date of the final notice of sale projected by the Department of the Interior or six months after the date of the request, whichever is later. The EPA regional administrator may, at his discretion, issue a project decision schedule for offshore oil and gas facilities in the territorial seas.

3. Nothing in 40 CFR 122.28(c) shall affect the authority of the EPA regional administrator to require an individual permit under 40 CFR 122.28(b)(3)(i)(A)-(G).
