# §124.53. State certification.

- (a) Under CWA [section 401(a)(1)](/cfr/40/401.md?p=a-1), EPA may not issue a permit until a certification is granted or waived in accordance with that section by the State in which the discharge originates or will originate.
- (b) Consistent with the requirements set forth in §§ [121.4](/cfr/40/121.4.md) and [121.5](/cfr/40/121.5.md) of this chapter, applications for individual permits may be forwarded by the Regional Administrator to the certifying State agency with a request to act on the request for certification consistent with [§ 121.7](/cfr/40/121.7.md) of this chapter.
- (c) If State certification has not been requested by the time the draft permit is prepared, the Regional Administrator shall send the certifying State agency a request for certification consistent with [§ 121.5](/cfr/40/121.5.md) of this chapter and include a copy of the draft permit.
- (d) State certification shall be granted or denied within the reasonable period of time as required under CWA [section 401(a)(1)](/cfr/40/401.md?p=a-1). The State shall send a notice of its action, including a copy of any certification, to the applicant and the Regional Administrator.
- (e) State certification on a draft permit may include a statement of the extent to which each condition of the draft permit can be made less stringent without violating the requirements of State law, including water quality standards.

# §124.54. Special provisions for State certification and concurrence on applications for section 301(h) variances.

- (a) When an application for a permit incorporating a variance request under CWA [section 301(h)](/cfr/40/301.md?p=h) is submitted to a State, the appropriate State official shall either:
  - (1) Deny the request for the CWA [section 301(h)](/cfr/40/301.md?p=h) variance (and so notify the applicant and EPA) and, if the State is an approved NPDES State and the permit is due for reissuance, process the permit application under normal procedures; or
  - (2) Forward a copy of the certification required under CWA [section 401(a)(1)](/cfr/40/401.md?p=a-1) to the Regional Administrator.
- (b) When EPA issues a tentative decision on the request for a variance under CWA [section 301(h)](/cfr/40/301.md?p=h), and no certification has been received under [paragraph (a)](#a) of this section, the Regional Administrator shall forward the tentative decision to the State. If the State fails to deny or grant certification and concurrence under [paragraph (a)](#a) of this section within the reasonable period of time provided in CWA [section 401(a)(1)](/cfr/40/401.md?p=a-1), certification shall be waived and the State shall be deemed to have concurred in the issuance of a CWA [section 301(h)](/cfr/40/301.md?p=h) variance.
- (c) Any certification provided by a State under [paragraph (a)(2)](#a-2) of this section shall constitute the State's concurrence (as required by [section 301(h)](/cfr/40/301.md?p=h)) in the issuance of the permit incorporating a [section 301(h)](/cfr/40/301.md?p=h) variance subject to any conditions specified therein by the State. CWA [section 301(h)](/cfr/40/301.md?p=h) certification and concurrence under this section will not be forwarded to the State by EPA for recertification after the permit issuance process; States must specify any conditions required by State law, including water quality standards, in the initial certification.

# §124.55. Effect of State certification.

- (a) When certification is required under CWA [section 401(a)(1)](/cfr/40/401.md?p=a-1), no final permit shall be issued:
  - (1) If certification is denied; or
  - (2) Unless the final permit incorporates the conditions specified in the certification.
- (b) A State may not condition or deny a certification on the grounds that State law allows a less stringent permit condition.
- (c) A condition in a draft permit may be changed during agency review in any manner consistent with a corresponding certification. No such changes shall require EPA to submit the permit to the State for recertification.
- (d) Review and appeals of limitations and conditions attributable to State certification shall be made through the applicable procedures of the State and may not be made through the procedures in this part.
- (e) Nothing in this section shall affect EPA's obligation to comply with [§ 122.47](/cfr/40/122.47.md). See CWA [section 301(b)(1)(C)](/cfr/40/301.md?p=b-1-C).
