Section 9VAC25-31-390 - Modification or revocation and reissuance of permitsA. 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 (including a change or changes in the permittee's sludge use or disposal practice) which occurred after permit issuance which 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 VPDES general permits this cause includes any information indicating that cumulative effects on the environment are unacceptable. For new source or new discharger VPDES 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standards, or the Secondary Treatment Regulations incorporated by reference in 9VAC25-31-30; and(2) EPA has revised, withdrawn, or modified that portion of the regulation or effluent limitation guideline on which the permit condition was based, or has approved a state action with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; orc. For changes based upon modified state certifications of VPDES 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 VPDES 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 9VAC25-31-100 L or M within the time specified in this chapter.6. When required to incorporate an applicable CWA § 307(a) toxic effluent standard or prohibition.7. When required by the reopener conditions in a permit which are established under 9VAC25-31-220 B or C or 9VAC25-31-800 E.8.a. Upon request of a permittee who qualifies for effluent limitations on a net basis under 9VAC25-31-230 G.b. When a discharger is no longer eligible for net limitations as provided in 9VAC25-31-230 G 1 b.9. As necessary under 9VAC25-31-800 E for a pretreatment program.10. Upon failure to notify another state whose waters may be affected by a discharge.11. When the level of discharge of any pollutant which is not limited in the permit exceeds the level which can be achieved by the technology-based treatment requirements appropriate to the permittee.12. To establish a notification level as provided in 9VAC25-31-220 F.13. To modify a schedule of compliance to reflect the time lost during construction of an innovative or alternative facility, in the case of a POTW which has received a grant under § 202(a)(3) of the CWA for 100% of the costs to modify or replace facilities constructed with a grant for innovative and alternative wastewater technology under § 202(a)(2) of the CWA. In no case shall the compliance schedule be modified to extend beyond an applicable CWA statutory deadline for compliance.14. To correct technical mistakes, such as errors in calculation, or mistaken interpretations of law made in determining permit conditions.15. When the discharger has installed the treatment technology considered by the permit writer in setting effluent limitations imposed under the 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).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 9VAC25-31-410, and the department determines that modification or revocation and reissuance is appropriate; or2. 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.9 Va.
