5.6 MODIFICATION OR REVOCATION AND REISSUANCE OF PERMIT The Director may determine whether or not one or more of the causes, listed in R317-8-5.6(1) and (2) for modification or revocation and reissuance or both, exist. If cause exists, the Director may modify or revoke and reissue the permit accordingly, and may request an updated application if necessary. When a permit is modified, only the conditions subject to modification are reopened. If a permit is revoked and reissued, the entire permit is reopened and subject to revision and the permit is reissued for a new term. If cause does not exist under this section, the Director shall not modify or revoke and reissue the permit. If a permit modification satisfies the criteria in R317-8-5.6(3) for "minor modifications" the permit may be modified without a draft permit or public review. Otherwise, a draft permit must be prepared and the procedures in R317-8-6 must be followed.
(1) Causes for Modification. The following are causes for modification but not revocation and reissuance of permits except when the permittee requests or agrees to revocation and reissuance as well as modification of a permit. (a) Alterations. If there are material and substantial alterations or additions made to the permitted facility or activity which occurred after permit issuance, such alterations may justify the application of revised permit conditions which are different or absent in the existing permit.(b) Information. Information received by the Director regarding permitted activities may show cause for modification. UPDES permits may be modified during their terms for this cause only if the information was not available at the time of permit issuance, (except for revised regulations, guidance or test methods) and would have justified application of different conditions at the time of permit issuance. In addition, the applicant must show that the information would have justified the application of different permit conditions at the time of issuance. For UPDES general permits this cause shall include any information indicating that cumulative effects on the environment are unacceptable.(c) New Regulations. If the standards or rules on which the permit was based have been changed by promulgation of amended standards or rules or by judicial decision after the permit was issued permits may be modified during their terms for this case only as follows: 1. For promulgation of amended standards or rules, when: a. The permit condition requested to be modified was based on promulgated effluent limitation guidelines or promulgated water quality standards; or the Secondary Treatment Regulations; andb. 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 the Director's action with regard to a water quality standard on which the permit condition was based; andc. A permittee requests modification in accordance with R317-8-6.1 within ninety (90) days after the amendment, revision or withdrawal is promulgated.2. 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 R317-8-6.2 within ninety (90) days of judicial remand.(d) Compliance Schedules. A permit may be modified if the Director 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 will a UPDES compliance schedule be modified to extend beyond an applicable statutory deadline in R317-8-7.(e) In addition the Director may modify a permit: 1. When the permittee has filed a request for a variance under R317-8-2.3, R317-8-2.7 or for "fundamentally different factors" within the time specified in R317-8-3 or R317-8-7.7(8) a (and the Director processes the request under the applicable provisions).2. When required to incorporate an applicable toxic effluent standard or prohibition under R317-8-4.2(2).3. When required by the "reopener" conditions in a permit, which are established in the permit under R317-8-4.2(3) for toxic effluent limitations and standards for sewage sludge use or disposal.4. Upon request of a permittee who qualifies for effluent limitations on a net basis under R317-8-4.3(8).5. When a discharger is no longer eligible for net limitations, as provided in R317-8-4.3(8).6. As necessary under EPA effluent limitations guidelines concerning compliance schedule for development of a pretreatment program.7. 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 under R317-8-7.1(2)(c).8. To establish a "notification level" as provided in R317-8-4.2(6).9. To modify a schedule of compliance to reflect the time lost during the construction of an innovative or alternative facility in the case of the POTW which has received a grant from EPA of 100% of the cost to modify or replace the facilities. In no case will the compliance schedule be modified to extend beyond an applicable statutory deadline for compliance.10. Upon failure of the Director to notify an affected state whose waters may be affected by a discharge from Utah.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 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. When required by a permit condition to incorporate a land application plan for beneficial reuse of sewage sludge, to revise an existing land application plan, or to add a land application plan.(2) Causes for Modification or Revocation and Reissuance. The following are causes to modify or alternatively revoke or reissue a permit: (a) Cause exists for termination under R317-8-5.7 and the Director determines that modification or revocation and reissuance is appropriate.(b) The Director 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.(3) Minor modifications of permits. Upon the consent of the permittee, the Director may modify a permit to make the corrections or allowances for changes in the permitted activity listed in this section, without following the procedures of R317-8-6. Any permit modification not processed as a minor modification under this section must be made for cause and with a Section R317-8-6 draft permit and public notice as required under this section. Minor modifications may only: (a) Correct typographical errors;(b) Require more frequent monitoring or reporting by the permittee;(c) Change an interim compliance date in a schedule of compliance, provided the new date is not more than 120 days after the date specified in the existing permit and does not interfere with attainment of the final compliance date requirement;(d) Allow for a change in ownership or operational control of a facility where the Director determines that no other change in the permit is necessary, provided that a written agreement containing a specific date for transfer of permit responsibility, coverage, and liability between the current and new permittees has been submitted to the ;Director(e) Change the construction schedule for a discharger which is a new source. No such change shall affect a disclosure obligation to have all pollution control equipment installed and in operation prior to discharge; or(f) Delete a point source outfall when the discharge from that outfall is terminated and does not result in discharge of pollutants from other outfalls except in accordance with permit limits.(g) Incorporate conditions of a POTW pretreatment program that has been approved in accordance with the procedures in R317-8-8.10 (or a modification thereto that has been approved in accordance with the procedures in R317-8-8.16 as enforceable conditions of the POTW's permits).
