9 Va. Admin. Code § 25-875-1230

Current through Register Vol. 40, No. 22, June 17, 2024

Section 9VAC25-875-1230 - [Effective 7/1/2024] Modification or revocation and reissuance of permits

A. Causes for modification. The following are causes for modification but not revocation and reissuance of permits except when the permittee requests or agrees.

1. There are material and substantial alterations or additions to the permitted facility or activity that occurred after permit issuance that justify the application of permit conditions that are different or absent in the existing permit.

2. The department has received new information. Permits may be modified during their terms for this cause only if the information was not available at the time of permit issuance (other than revised regulations, guidance, or test methods) and would have justified the application of different permit conditions at the time of issuance. For general permits this cause includes any information indicating that cumulative effects on the environment are unacceptable. For new source or new discharger permits this cause shall include any significant information derived from effluent testing required on the permit application after issuance of the permit.

3. The standards or regulations on which the permit was based have been changed by promulgation of amended standards or regulations or by judicial decision after the permit was issued. Permits may be modified during their terms for this cause only as follows:

a. For promulgation of amended standards or regulations, when:

(1) The permit condition requested to be modified was based on a promulgated effluent limitation guideline, EPA approved, or promulgated water quality standards;

(2) EPA has revised, withdrawn, or modified that portion of the regulation or effluent limitation guideline on which the permit condition was based or has approved a state action with regard to a water quality standard on which the permit condition was based; and

(3) A permittee requests modification in accordance with this chapter within 90 days after Federal Register notice of the action on which the request is based;

b. For judicial decisions, a court of competent jurisdiction has remanded and stayed EPA promulgated regulations or effluent limitation guidelines, if the remand and stay concern that portion of the regulations or guidelines on which the permit condition was based and a request is filed by the permittee in accordance with this chapter within 90 days of judicial remand; or

c. For changes based upon modified state certifications of permits.

4. The department determines good cause exists for modification of a compliance schedule, such as an act of God, strike, flood, or materials shortage, or other events over which the permittee has little or no control and for which there is no reasonably available remedy. However, in no case may a compliance schedule be modified to extend beyond an applicable CWA statutory deadline.

5. When the permittee has filed a request for a variance pursuant to 9VAC25-875-920 G within the time specified in this chapter.

6. When required to incorporate an applicable § 307(a) of the CWA toxic effluent standard or prohibition.

7. When required by the reopener conditions in a permit that are established under 9VAC25-875-1030 B.

8. Upon failure to notify another state whose waters may be affected by a discharge.

9. When the level of discharge of any pollutant that is not limited in the permit exceeds the level that can be achieved by the technology-based treatment requirements appropriate to the permittee.

10. To establish a notification level as provided in 9VAC25-875-1030 E.

11. To correct technical mistakes, such as errors in calculation, or mistaken interpretations of law made in determining permit conditions.

12. When the discharger has installed the treatment technology considered by the permit writer in setting effluent limitations imposed under the State Water Control Law and § 402(a)(1) of the CWA and has properly operated and maintained the facilities but nevertheless has been unable to achieve those effluent limitations. In this case, the limitations in the modified permit may reflect the level of pollutant control actually achieved but shall not be less stringent than required by a subsequently promulgated effluent limitations guideline.

13. For a small MS4, to include an effluent limitation requiring implementation of a minimum control measure or measures as specified in 9VAC25-875-970 D 2 when:

a. The permit does not include such measures based upon the determination that another entity was responsible for implementation of the requirements; and

b. The other entity fails to implement measures that satisfy the requirements.

B. Causes for modification or revocation and reissuance. The following are causes to modify or, alternatively, revoke and reissue a permit:

1. Cause exists for termination under 9VAC25-875-1250, and the department determines that modification or revocation and reissuance is appropriate; or

2. The department has received notification of a proposed transfer of the permit. A permit also may be modified to reflect a transfer after the effective date of an automatic transfer but will not be revoked and reissued after the effective date of the transfer except upon the request of the new permittee.
