58.01.25.201. MODIFICATION, OR REVOCATION AND REISSUANCE OF IPDES PERMITS

01. Procedures to Modify, or Revoke and Reissue Permits. (3-20-20)T

a. Permits may be modified, or revoked and reissued either at the request of any interested person (including the permittee) or upon the Department's initiative. However, permits may only be modified or revoked and reissued for the reasons specified in Subsection 201.02. All requests shall be in writing and shall contain facts or reasons supporting the request. (3-20-20)T

b. If the Department tentatively decides to modify or revoke and reissue a permit, the Department shall prepare a draft permit under Section 108 (Draft Permit and Fact Sheet), incorporating the proposed changes. (3-20-20)T

i. The Department may request additional information and, in the case of a modified permit, may require the submission of an updated application. If the tentative decision is to revoke and reissue a permit, the Department shall require the submission of a new application. (3-20-20)T

ii. In a permit modification under this section, only those conditions to be modified shall be reopened when a new draft permit is prepared. All other aspects of the existing permit shall remain in effect for the duration of the unmodified permit. (3-20-20)T

iii. When a permit is revoked and reissued under this section, the entire permit is reopened just as if the permit had expired and was being reissued. During any revocation and reissuance proceeding, the permittee shall comply with all conditions of the existing permit until a new final permit is reissued. (3-20-20)T

iv. Minor modifications, as defined in Subsection 201.03, do not require the development of a draft permit, fact sheet, nor must minor modifications be subjected to public notification and comment. (3-20-20)T

02. Causes to Modify, or Revoke and Reissue Permits. When the Department receives any pertinent information (for example, inspects the facility, receives information submitted by the permittee as required in the permit, receives a request for modification or revocation and reissuance under Subsection 201.01, or conducts a review of the permit file), the Department may determine whether or not one (1) or more of the causes listed in Subsections 201.02.c. and 201.02.d. for modification or revocation and reissuance or both exist. (3-20-20)T

a. If cause exists, the Department may modify or revoke and reissue the permit accordingly, subject to the limitations of Subsection 201.01.b., and may request a new or updated application, if necessary. (3-20-20)T

b. If cause does not exist under this section, the Department shall not modify or revoke and reissue the permit. (3-20-20)T

c. The following are causes for modification but not revocation and reissuance of permits except when the permittee requests or agrees: (3-20-20)T

i. 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, and which justify the application of permit conditions that are different or absent in the existing permit. (3-20-20)T

ii. 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: (3-20-20)T

(1) For IPDES general permits (Section 130) this cause includes any information indicating that cumulative effects on the environment are unacceptable; and (3-20-20)T

(2) For new source or new discharger IPDES permits (Section 120), this cause shall include any significant information derived from effluent testing required under Subsection 105.08 or 105.16 after issuance of the permit. (3-20-20)T

iii. 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: (3-20-20)T

(1) For promulgation of amended standards or regulations, when: (3-20-20)T

(a) 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 under 40 CFR Part 133; (3-20-20)T

(b) 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 (3-20-20)T

(c) A permittee requests modification in accordance with Subsection 201.01 or 203.01 within ninety (90) days after notice of the action on which the request is based; and (3-20-20)T

(2) For judicial decisions, a court of competent jurisdiction has remanded and stayed EPA or Idaho promulgated regulations or effluent limitation guidelines, if the remand and stay concerns 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 Subsection 201.01 or 203.01 within ninety (90) days of judicial remand. (3-20-20)T

iv. 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 an IPDES compliance schedule be modified to extend beyond an applicable Clean Water Act statutory deadline. (3-20-20)T

v. When the permittee has filed a request for a variance under Clean Water Act section 301(c), 301(g), 301(i), 301(k), or 316(a) or for fundamentally different factors within the time specified in Section 310 (Variances). (3-20-20)T

viii. Upon request of a permittee who qualifies for effluent limitations on a net basis, or when a discharger is no longer eligible for net limitations, as provided in Subsection 303.07. (3-20-20)T

ix. As necessary under 40 CFR 403.8(e) (Pretreatment Program Requirements: Development and Implementation by POTW). (3-20-20)T

x. Upon failure of an approved state to notify, as required by the Clean Water Act section 402(b)(3), another state whose waters may be affected by a discharge from the approved state. (3-20-20)T

xi. 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 40 CFR 125.3(c). (3-20-20)T

xii. To establish a notification level as provided in Subsection 302.08. (3-20-20)T

xiii. 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 loan under IDAPA 58.01.12, "Rules for Administration of Water Pollution Control Loans." In no case shall the compliance schedule be modified to extend beyond an applicable Clean Water Act statutory deadline. (3-20-20)T

xiv. For a small MS4, to include an effluent limitation requiring implementation of a minimum control measure or measures as specified in 40 CFR 122.34(b) when: (3-20-20)T

(1) The permit does not include such measure(s) based upon the determination that another entity was responsible for implementation of the requirement(s), and (3-20-20)T

xv. To correct technical mistakes, such as errors in calculation, or mistaken interpretations of law made in determining permit conditions. (3-20-20)T

xvi. When the discharger has installed the treatment technology considered by the permit writer in setting effluent limitations imposed under the Clean Water Act section 402(a)(1) 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). (3-20-20)T

xvii. The incorporation of the terms of a CAFO's nutrient management plan into the terms and conditions of a general permit when a CAFO obtains coverage under a general permit in accordance with 40 CFR 122.23(h) and Section 130 (General Permits) is not a cause for modification pursuant to the requirements of this section. (3-20-20)T

xviii. When required by a permit condition to incorporate a land application or sludge disposal plan for beneficial reuse of sewage sludge, to revise an existing land application or sludge disposal plan, or to add a land application or sludge disposal plan as required by IDAPA 58.01.16.650, "Wastewater Rules, " and Section 380 (Sewage Sludge) of these rules. (3-20-20)T

d. The following are causes to modify or, alternatively, revoke and reissue a permit: (3-20-20)T

i. Cause exists for termination under Subsection 203.03, and the Department determines that modification or revocation and reissuance is appropriate; (3-20-20)T

03. Minor Modifications of Permits. Upon the consent of the permittee, the Department may modify a permit to make the corrections or allowances for changes in the permitted activity listed in this subsection without following the procedures of Sections 108 (Draft Permit and Fact Sheet), 109 (Public Notification and Comment), and Subsection 201.01. Any permit modification not processed as a minor modification under this subsection must be made for cause and must meet the requirements of Section 108 (Draft Permit and Fact Sheet) and Section 109 (Public Notification and Comment). Minor modifications may: (3-20-20)T

a. Correct typographical errors; (3-20-20)T

b. Require more frequent monitoring or reporting by the permittee; (3-20-20)T

d. Allow for a change in ownership or operational control of a facility where the Department 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 permittee has been submitted to the Department; (3-20-20)T

e. Change the construction schedule for a discharger which is a new source. No such change shall affect a discharger's obligation to have all pollution control equipment installed and in operation prior to discharge under Section 120 (New Sources and New Discharges), and 40 CFR 122.29(d); (3-20-20)T
