(3-24-22)

iii. For general permits issued under Subsection 130.01.b. for small MS4s, the Department must establish the terms and conditions necessary to meet the requirements of 40 CFR 122.34 using one (1) of the two (2) permitting approaches described in Subsections 130.01.d.iii(1) and (2). The Department must indicate in the permit or fact sheet which approach is being used. (3-24-22)
(1) Comprehensive general permit. The Department includes all required permit terms and conditions in the general permit; or (3-24-22)

(2) Two-step general permit.

(3-24-22)
(a) The general permit must require that any small MS4 operator seeking authorization to discharge under the general permit submit a Notice of Intent (NOI) consisting of the minimum required information in Subsection 130.05.b., and any other information the Director identifies as necessary to establish additional terms and conditions that satisfy the permit requirements of 40 CFR 122.34, such as the information required under Subsection 130.05.b.

The Department may require the small MS4 operator to submit additional information. If the Department makes a preliminary decision to authorize the small MS4 operator to discharge under the general permit, the Department must give the public notice of and opportunity to comment and request a public meeting on its proposed authorization and the NOI, the proposed additional terms and conditions, and the basis for these additional requirements. The public notice, the process for submitting public comments and meeting requests, and the meeting process if a request for a meeting is granted, must follow the procedures applicable to draft permits set forth in Sections 108 and 109 except Subsection 109.01.d. The Department must respond to significant comments received during the comment period as provided in Subsection 109.03. (3-24-22)

(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.

c. The Department may terminate, revoke, or deny coverage under a general permit, and require the discharger or applicant to apply for and obtain an individual IPDES permit. Any interested person may petition the Department to take action under this subsection. Cases where an individual IPDES permit may be required include the following: (3-24-22)
i. The discharger or TWTDS is not in compliance with the conditions of the general permit; (3-24-22)

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 TWTDS; (3-24-22)

vii. The discharge(s) is a significant contributor of pollutants. In making this determination, the Department may consider the following factors: (3-24-22)
(1) The location of the discharge with respect to waters of the United States; (3-24-22)

(2) The size of the discharge; (3-24-22)

(3) The quantity and nature of the pollutants discharged to waters of the United States; and (3-24-22)

(4) Other relevant factors. (3-24-22)

d. 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. (3-24-22)

iii. The Department shall grant a request by issuing an individual permit if the reasons cited by the owner or operator are adequate to support the request. (3-24-22)

e. When an individual IPDES permit is issued to an owner or operator otherwise subject to a general IPDES permit, the applicability of the general permit to the individual IPDES permittee is automatically terminated on the effective date of the individual permit. (3-24-22)

f. 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. (3-24-22)

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, a statement that on the effective date of the individual IPDES permit, the general permit as it applies to the individual permittee shall automatically terminate, and a statement that the owner or operator may appeal the Department's decision as provided in Section 204 (Appeals Process). The Department may grant additional time upon request of the applicant. (3-24-22)

b. Prior to a case-by-case determination that an individual permit is required for a storm water discharge under this section (see 40 CFR 122.26(a)(1)(v), (a)(9)(iii), and Subsection 105.19), the Department may require the discharger to submit a permit application or other information regarding the discharge described in the Clean Water Act section 308.
