Rule 391-3-6-.09 - Requirements for Approval and Implementation of Publicly Owned Treatment Works Pretreatment Programs and Administration of the EPD Pretreatment Program

Universal Citation: GA Rules and Regs r 391-3-6-.09

Current through Rules and Regulations filed through December 18, 2024

(1) Purpose. The purpose of Rule 391-3-6-.09 is to provide uniform procedures and practices to be followed for the development and submission of POTW pretreatment programs for EPD review and approval or denial, and the public notification methods to be used.

(2) Definitions. All terms used in this Rule shall be interpreted in accordance with the definitions as set forth in the Act unless otherwise defined in this Paragraph or in any other Rules of this Chapter:

(a) "Submission" means a request to the Approval Authority for approval of a POTW pretreatment program by a POTW.

(3) Required POTW Pretreatment Programs.

(a) Any POTW or combination of POTWs operated by the same authority with a total design flow greater than 5 million gallons per day (MGD) and receiving from industrial users pollutants which may pass through untreated or interfere with the operation of the POTW or are otherwise subjects to Section 307(b) or 307(c) of the Federal Act will be required to establish a POTW pretreatment program.

(b) The Approval Authority may require in writing that a POTW with a design flow of 5 mgd or less develop a POTW pretreatment program if it finds that the nature or volume of the industrial effluent, treatment process upsets, violations of POTW effluent limitations, contamination of municipal sludge or other circumstances warrant a POTW pretreatment program in order to prevent interference with the POTW or pass through of untreated pollutants.

(c) Any POTW described in Subparagraphs 391-3-6-.09(3)(a) and (b) must obtain approval of its POTW pretreatment program no later than three (3) years after the reissuance or modification of its existing NPDES permit, but in no case later than July 1, 1983. POTWs whose NPDES permits are modified under Section 301(h) of the Federal Act shall have a pretreatment program within less than three (3) years as provided by 40 CFR Part 125, Subpart G. POTWs identified after July 1, 1983 as being required to develop a POTW pretreatment program under Subparagraph 391-3-6-09(3)(a) and (b) shall develop and submit such a program for approval as soon as possible to the Approval Authority but in no case later than one (1) year after written notification from the Approval Authority of such identification.

(d) The POTW pretreatment program shall meet the criteria set forth in 40 CFR 403.8(f) and shall be capable of being administered by the POTW to ensure compliance by the industrial users with applicable State and Federal pretreatment standards and requirements in order to be approved by the Approval Authority.

(e) The Approval Authority may hold a public hearing in the geographical area served by any POTW which fails to comply with the Approval Authority's finding and written directive that a POTW pretreatment program is required and a draft submission must be developed and submitted to the Approval Authority within sixty (60) days. The public hearing will be held to advise the public, the industrial users and other concerned parties that the EPD will establish and operate the pretreatment program necessary to meet the Federal requirements as a result of the failure of the POTW to carry out its legal responsibility. The appropriate POTW, city or municipal officials will be requested at the public hearing to explain the reasons why they failed to comply with the Approval Authority's finding and directive. For any public hearing held pursuant to this Subparagraph a public notice shall be provided at least forty-five (45) days in advance of the hearing date and shall be published and circulated in accordance with Subparagraph 391-3-6-.09(5)(a).

(f) A POTW requesting approval of a POTW pretreatment program shall develop a program submission which includes the information set forth in 40 CFR 403.9(b) and 403.8(f). Any other pertinent information requested by the Director as being necessary to clarify, support or supplement the program description must also be submitted.

(4) POTW Pretreatment Program Approval or Denial.

(a) Any POTW requesting POTW pretreatment program approval shall submit to the EPD three copies of the submission described in 40 CFR 403.9(b). Within 60 days after receiving the submission, the EPD shall make a preliminary determination of whether the submission meets the requirements of 403.9(b) and whether the submission meets the requirements as may be described by the EPD. When the EPD is satisfied that a POTW pretreatment program meets the requirements of 40 CFR 403.8(f), 403.9(b) and such other requirements as may be prescribed by the Approval Authority, the EPD shall notify the POTW that the submission has been received and is under review and commence public notice and evaluation activities set forth in Subparagraph 391-3-6-.09(5).

(b) When the EPD determines that the POTW pretreatment program does not meet the requirements of Subparagraph 391-3-6-.09(4)(a), the EPD shall notify the POTW in writing as appropriate and each person who has requested individual notice. This notification shall identify any defects in the submission and advise the POTW and each person who has requested individual notice of the means by which the POTW can comply with the applicable requirements of Subparagraph 391-3-6-.09(4)(a). Unless the necessary revisions and modifications are made within the time period specified in the notification of denial, not to exceed the one year period specified in Subparagraph 391-3-6-.09(3)(c), the EPD will proceed to develop and implement a pretreatment program for the area served by the POTW in accordance with Rules 391-3-6-.08 and 391-3-6-.09.

(5) Notice and Public Participation.

(a) Tentative Determination for POTW Pretreatment Program Approval.

1. Within 20 work days after the EPD has made a determination that a POTW pretreatment program submission meets the requirements of 40 CFR 403.9(b), a public notice will be issued by the EPD and the city or municipality requesting approval to advise the public that a request has been made for approval of the submission. This public notice shall be published and circulated in a manner designed to inform interested and potentially interested persons of the submission. Procedures for circulation of the public notice shall include the following:

(i) notice to adjoining State whose waters may be affected;

(ii) notice to section 208 Designated Planning Agencies; Federal and State fish, shellfish and wildlife resources agencies and, upon request, to other appropriate government agencies;

(iii) publication in a newspaper(s) of general circulation within the city or municipality in which the POTW pretreatment program has been established;

(iv) notice to the chief elected official of the city or municipality requesting approval of the POTW pretreatment program submission;

(v) a copy will be available at the EPD office in Atlanta, posted to the EPD website, and an electronic mailing (e-mail) notification of the public notice will be provided to those persons or groups included on the electronic mailing list to receive such notices. The EPD shall maintain an electronic mailing list for distribution of public notices. Any person or group may request that their e-mail address be added to the electronic mailing list or they may sign-up through the EPD website;

(vi) the EPD shall provide a period of not less than forty-five (45) days following the date of the public notice during which interested persons may submit their written views on the submission. All written comments submitted during the forty-five day period will be retained by the EPD and considered in the decision on whether or not to approve the submission. The comment period may be extended at the discretion of the Approval Authority; and

(vii) the contents of the public notice will be in accordance with appropriate Federal requirements and applicable State laws.

2. The Approval Authority shall provide an opportunity for the applicant, any affected State, any interested State or Federal agency, person or group of persons to request a public hearing with respect to the submission. Any such request for a public hearing shall be filed within the forty-five (45) day comment period described in Subparagraph 391-3-6-.09(5)(a) 1.(vi) and shall indicate the interest of the person filing such request and the reason why a hearing is warranted. The Approval Authority shall hold the hearing if it determines that there is sufficient public interest in holding such hearing or if the POTW requests a hearing.

(i) any public hearing held pursuant to this Subparagraph shall be held in the geographical area of the applicable submission or other appropriate location at the discretion of the Approval Authority. The Approval Authority may hold one public hearing on related groups of submissions in the same geographical area;

(ii) public notice of any hearing held pursuant to this Subparagraph shall be provided at least forty-five (45) days advance of the hearing date and shall be circulated in accordance with Subparagraph 391-3-6-.09(5)(a) 1.

(b) Final Determination for POTW Pretreatment Program Approval or Denial.

1. Deadline for review of submission. The Approval Authority shall have 90 days from the date of public notice of any submission complying with the requirements of § 403.9(b) to review the submission. The Approval Authority shall review the submission to determine compliance with the requirements of 40 CFR 403.8(b) and (f). The Approval Authority may have up to an additional 90 days to complete the evaluation of the submission if the public comment period provided for in Subparagraph 391-3-6-.09(5)(a) 1.(vi) is extended beyond 45 days or if a public hearing is held as provided for in Subparagraph 391-3-6-.09(5)(a) 2. In no event, however, shall the time for evaluation of the submission exceed a total of 180 days from the date of public notice of a submission meeting the requirements of § 403.9(b).

2. At the conclusion of the public notice comment period or the public comment period allowed following a public hearing or the extension if warranted per Subparagraph 391-3-6-.09(5)(b) 1. above, the Approval Authority shall make a determination to approve the POTW pretreatment program or deny any approval to the program based on the requirements of Subparagraph 391-3-6-.09(4) and taking into consideration the comments submitted during the comment period and the record of the public hearing, if held. When the Approval Authority has made a determination to deny approval to the program the POTW shall be notified in writing in accordance with Subparagraph 391-3-6-.09(4)(b) and each person who has requested individual notice. The Approval Authority shall also notify these persons who submitted comments and participated in the public hearing, if held, of the approval or disapproval of the submission.

3. U.S. EPA's objection to Approval Authority's decision. No POTW pretreatment program shall be approved by the Approval Authority if, following the 45 day (or extended) evaluation period provided for in Subparagraph 391-3-6-.09(5)(a) 1.(vi) and any hearing held pursuant to Subparagraph 391-3-6-.09(5)(a) 2 of this section, the Regional Administrator of U.S. Environmental Protection Agency Region 4 (Regional Administrator) sets forth in writing objections to the approval of such submission and the reasons for such objections. A copy of the Regional Administrator's objections shall be provided to the applicant, and each person who has requested individual notice. The Regional Administrator shall provide an opportunity for written comments and may convene a public hearing on his or her objections. Unless retracted, the Regional Administrator's objections shall constitute a final ruling to deny approval of a POTW pretreatment program 90 days after the date the objections are issued.

4. When the EPD has made a determination to approve the submission, a public notice shall be issued to advise of the decision. This public notice shall be published and circulated in a manner designed to inform interested and potentially interested persons of the decision. Procedures for circulation of the public notice shall include the following:

(i) publication in the same newspaper as the original notice of request for approval of the submission was published;

(ii) providing notice to those persons who submitted comments and participated in the hearing for approval or disapproval of the submission;

(iii) the Approval Authority shall ensure that the submission and any comments upon said submission are available to the public for inspection and copying at the EPD offices in Atlanta during normal business hours;

(iv) providing notice to adjoining State whose waters may be affected; and

(v) providing notice to section 208 Designated Planning Agencies; Federal and State fish, shellfish and wildlife resource agencies and, upon request, to other appropriate government agencies.

1. A copy of the program submission, and other forms related thereto, including written public comments and comments of all governmental agencies thereon and other reports, files and information not involving methods or processes entitled to protection as trade secrets, may be available online and will be available for public inspection and copying during normal business hours at the EPD office in Atlanta. Effluent data shall not be considered as information entitled to protection. Public access to NPDES information shall be in accordance with Federal Regulations, 40 C.F.R. 122.7;

2. Any information submitted with reports, records or plans that is considered confidential by the POTW, and that is not specifically excluded in subparagraph (c)1. above, should be clearly labeled "Confidential" and be supported by a statement as to the reason that such information should be considered confidential. If the Director, with the concurrence of the Regional Administrator, determines that such information is entitled to confidential protection, he shall label and handle same accordingly;

3. Any information accorded confidential status whether or not contained in a program submission shall be made available, upon written request, to the Regional Administrator or his authorized representative who shall maintain the information as confidential.

(6) Notification of POTW Pretreatment Program Approval.

(a) Notification of any final approval of a POTW pretreatment program will be forwarded to the POTW in writing including any conditions or special requirements for compliance schedules, monitoring and reporting both for the POTW and the industrial user in accordance with 40 CFR 403.12.

(b) When the POTW accepts the approval and any specific conditions or requirements that are a part of the approval notification by the Approval Authority, procedures will be started to revise, modify and reissue the POTW's discharge permit to include compliance with Rules 391-3-6-.08 and 391-3-6-.09, and the approved POTW pretreatment program as enforceable conditions of the POTW's permit. The modification of a POTW's discharge permit for the purposes of incorporating a POTW pretreatment program approved by the Approval Authority in accordance with 40 CFR 403.11 and this Rule shall be deemed a minor permit modification subject to the procedures in 40 CFR 122.63.

(7) Modification of POTW Pretreatment Program.

(a) Either the EPD or a POTW with an approved POTW pretreatment program may initiate program modification at any time to reflect exchanging conditions at the POTW. Program modification is necessary whenever there is a significant change in the operation of the POTW pretreatment program that differs from the information in the POTW submission as approved by the Approval Authority. Any approved POTW pretreatment program identified by the EPD that needs to modify its program to incorporate requirements that have resulted from revision to Rule 391-3-6-.08 through 391-3-6-.10 or any other applicable rule revision shall develop and submit to the EPD for approval such program modification no later than one (1) year after written notification from the EPD to modify the program.

(b) POTW pretreatment program modifications shall be accomplished as follows:

1. For substantial modifications as defined in Subparagraph 391-3-6-.09(7)(c):

(i) the POTW shall submit to the EPD a statement of the basis for the desired modification, a modified program description or such other documents the Approval Authority determines to be necessary under the circumstances;

(ii) the Approval Authority shall approve or disapprove the modifications based on the requirements of 40 CFR 403.8(f), following the procedures in Subparagraph 391-3-6-.09(4) -(6);

(iii) the modification shall be incorporated into the POTW discharge permit after approval. The POTW's discharge permit will be modified to incorporate the approved modification in accordance with 40 CFR 122.63(g);

(iv) the modification shall become effective upon approval by the Approval Authority. Notice of approval shall be published in the same newspaper as the notice of original request for approval of the modification under Subparagraph 391-3-6-.09(5)(a) 1.(iii).

2. The POTW shall notify the EPD of any other (i.e., non-substantial) modifications to its pretreatment program at least thirty (30) days prior to when they are to be implemented by the POTW, in a statement similar to that provided for in Subparagraph 391-3-6-.09(7)(b) 1.(i). Such non-substantial program modification shall be deemed to be approved by the Approval Authority, unless the EPD determines that a modification submitted is in fact a substantial modification thirty (30) days after the submission of the POTWs statement. Following such approval by the Approval Authority, such modifications shall be incorporated into the POTW's discharge permit in accordance with 40 CFR 122.63(g). If the EPD determines that a modification reported by a POTW in its statement is in fact a substantial modification, the EPD shall notify the POTW and initiate the procedures in Subparagraph 391-3-6-.09(7)(b) 1.

1. The following are substantial modifications for purposes of this Subparagraph:

(i) changes to the POTW's legal authorities;

(ii) changes to local limits;

(iii) changes to the POTW's control mechanism as described in 40 CFR 403.8(f)(1)(iii);

(iv) changes to the POTW's method for implementing categorical pretreatment standards;

(v) a decrease in the frequency of self-monitoring or reporting required of industrial users;

(vi) a decrease in the frequency of industrial user inspection or sampling by the POTW;

(vii) changes to the POTW's confidentiality procedures;

(viii) significant reduction in the POTW's pretreatment program resources (including personnel commitments, equipment, and funding levels); or

(ix) changes in the POTW's sludge disposal and management practices.

2. The Approval Authority may designate other specific modifications in additional to those listed in Subparagraph 391-3-6-.09(7)(c) 1. as substantial modifications.

3. A modification that is not included in Subparagraph 391-3-6-.09(7)(c) 1. is none the less a substantial modification for purposes of this Subparagraph if the modification:

(i) would have a significant impact on the operation of the POTW's pretreatment program;

(ii) would result in an increase in pollutant loadings at the POTW's or

(iii) would result in less stringent requirements being imposed on industrial users of the POTW.

(d) The POTW shall prepare a list of its industrial users meeting the criteria in Subparagraphs 391-3-6-.08(2)(u) 1.(i) and 2. applicable to each industrial user and, for industrial users meeting the criteria in Subparagraphs 391-3-6-.08(2)(u) 1.(ii) shall also indicate whether the POTW has made a determination pursuant to Subparagraph 391-3-6-.08(2)(u) that such industrial user should be considered a significant industrial user. This list, and any subsequent modification thereto, shall be submitted to the EPD as a nonsubstantial program modification pursuant to Subparagraph 391-3-6-.09(7)(b) 2. Discretionary designations or de-designations by the POTW pretreatment program shall be deemed to be approved by the EPD ninety (90) days after submission of the list or modifications thereto, unless EPD determines that a modification is in fact a substantial modification.

(8) Compliance Monitoring and Reporting Requirements for POTW Pretreatment Programs and the EPD Pretreatment Program.

(a) Both the EPD and each POTW pretreatment program shall develop and implement procedures to ensure compliance with the requirements of a pretreatment program. At a minimum, these procedures shall enable the Control Authority to:

1. Identify and locate all possible industrial users which might be subject to the pretreatment program;

2. Identify the character and volume of pollutants contributed to the POTW by the industrial users identified under Subparagraph 391-3-6-.09(8)(a) 1.;

3. Notify industrial users identified under Subparagraph 391-3-6-.09(8)(a) 1. of applicable pretreatment standards and applicable pretreatment requirements under Sections 204(b) and 405 of the Federal Act and Subtitles C and D of the Resource Conversation and Recovery Act. Within 30 days of approval pursuant to 40 CFR 403.8(f)(6), of a list of significant industrial users, notify each significant industrial user of its status as such and all requirements applicable to it as a result of such status;

4. Receive and analyze self-monitoring reports and other notices submitted by industrial users in accordance with the self-monitoring requirements in 40 CFR 403.12;

5. Randomly sample and analyze the effluent from industrial users and conduct surveillance activities in order to identify, independent of information supplied by industrial users, occasional and continuing noncompliance with pretreatment standards. Inspect and sample the effluent from each significant industrial user at least once a year except as otherwise specified below:

(i) Where the Control Authority has authorized the industrial user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard in accordance with 40 CFR 403.12(e)(3), the Control Authority must sample for the waived pollutant(s) at least once during the term of the categorical industrial user's control mechanism. In the event that the Control Authority subsequently determines that a waived pollutant is present or is expected to be present in the industrial user's wastewater based on changes that occur in the industrial user's operations, the Control Authority must immediately begin at least annual effluent monitoring of the industrial user's discharge and inspection.

(ii) Where the Control Authority has determined that an industrial user meets the criteria for classification as a Non-Significant Categorical Industrial User, the Control Authority must evaluate, at least once per year, whether an industrial user continues to meet the criteria in 40 CFR 403.3(v)(2).

(iii) In the case of industrial users subject to reduced reporting requirements under 40 CFR 403.12(e)(3), the Control Authority must randomly sample and analyze the effluent from industrial users and conduct inspections at least once every two years. If the industrial user no longer meets the conditions for reduced reporting in 40 CFR 403.12(e)(3), the Control Authority must immediately begin sampling and inspecting the industrial user at least once a year.

6. Evaluate, within one year whether each such significant industrial user needs a plan or other action to control slug discharges. Additional significant industrial users must be evaluated within 1 year of being designated a significant industrial user. If the Control Authority decides that a slug control plan is needed, the plan shall be based on the requirements in 40 CFR 403.8(f)(2)(vi).

7. Investigate instances of noncompliance with pretreatment standards and requirements, as indicated in the reports and notices required under 40 CFR 403.12 or indicated by analysis, inspection, and surveillance activities described in Subparagraph 391-3-6-.09(8)(a) 5. Sample taking and analysis and the collection of other information shall be performed using appropriate procedures to produce evidence admissible in enforcement proceedings or in judicial actions;

8. Comply with the public participation requirement of 40 CFR Parts 25 in the enforcement of national pretreatment standards. These procedures shall include provision for at least annual public notification, in a newspaper(s) of general circulation that provides meaningful public notice within the jurisdiction(s) served by the POTW of industrial users which, at any time during the previous 12 months, were in significant noncompliance with applicable pretreatment requirement as defined under Subparagraph 391-3-6-.08(2)(v); and

9. Deny or condition new increased contributions of pollutants, to the POTW by industrial users where such contributions do not meet applicable pretreatment standards and requirements or where such contribution would cause the POTW to violate its NPDES Permit.

(b) Both the EPD pretreatment program and each POTW pretreatment program shall require the following industrial user reports and notification for their regulated industrial users:

1. Notice of potential problems including slug loading as described in 40 CFR 403.12(f);

2. Report on the monitoring and analysis to demonstrate continued compliance as described in 40 CFR 403.12(g)(1)-(6);

3. Reports for industrial users not subject to categorical pretreatment standards as described in 40 CFR 403.12(h);

4. Notification of changed discharge as described under 40 CFR 403.12(j);

5. Notification of discharge of hazardous waste as described in 403.12(p)(1)-(4).

6. Baseline reports as described in 40 CFR 403.12(b)(1)-(7);

7. Compliance scheduling and progress reports as described in 40 CFR 403.12(c)(1)-(3);

8. Report on compliance with categorical pretreatment standards deadlines as described in 40 CFR 403.12(d);

9. Periodic reports on continued compliance as described in 40 CFR 403.12(e)(1)-(5); and

10. Annual certification by Non-Significant Categorical Industrial Users (as defined in Subparagraph 391-3-6-.08(2)(r)(2)) as required in 40 CFR 403.12(q).

(c) Signatory requirements for industrial user reports and POTW pretreatment program reports shall comply with requirements described in 40 CFR 403.12(l) and (m), respectively.

(d) Records keeping for industrial users and POTW pretreatment programs shall comply with the requirements described in 40 CFR 403.12(o).

(e) The EPD may require a POTW pretreatment program to sample and analyze the POTW influent, effluent and/or sludge for the toxic priority pollutants as listed under Subparagraphs 391-3-6-.03(5)(e)(i)(ii) and (iii) and any other identified pollutants at a frequency that adequately characterizes pollutant loading at the POTW. In addition, the POTW pretreatment program may be required to conduct biomonitoring of the POTW effluent.

(f) The federal NPDES Electronic Reporting rule, 40 CFR Part 127 and associated amendments (including amendments to 40 CFR 403.12), became effective on December 21, 2015. The requirements of this paragraph may include electronic reporting, as applicable and approved by EPD or the Control Authority. A Control Authority that receives electronic documents must satisfy the requirements of 40 CFR Part 3 (Electronic Reporting) and the NPDES Electronic Reporting rule.

(9) Legal Authority Requirements for Control Authorities.

(a) Each Control Authority shall operate pursuant to a legal authority enforceable in Federal, State or local courts, which authorizes or enables the Control Authority to apply and to enforce the requirements of sections 307(b) and (c), and 402(b)(8) of the Federal Act and any regulations implementing those sections. Such authority may be contained in a statute, ordinance, or series of contracts or joint powers agreement, which the Control Authority is authorized to enact, enter into or implement and which are authorized by the Act or State law. At a minimum, this legal authority shall enable the Control Authority to:

1. Require compliance with applicable pretreatment standards and requirements by industrial users.

2. Deny or condition new or increased contributions of pollutants, or changes in the nature of pollutants, to the POTW by industrial users where such contributions do not meet applicable pretreatment standards and requirements or where such contributions would cause the POTW to violate its NPDES permit.

3. Control through permit, order, or similar means, the contribution to the POTW by each industrial user to ensure compliance with applicable pretreatment standards and requirements. In case of industrial users identified as significant under Subparagraph 391-3-6-.08(2)(u), this control shall be achieved through individual permits or equivalent individual control mechanism issued to each such user except as follows.

(i) At the discretion of the Control Authority, this control may include use of general control mechanisms if the following conditions are met. All of the facilities to be covered must:

(I) Involve the same or substantially similar types of operations;

(II) Discharge the same types of wastes;

(III) Require the same effluent limitations;

(IV) Require the same or similar monitoring; and

(V) In the opinion of the Control Authority, are more appropriately controlled under a general control mechanism than under individual control mechanisms.

(ii) To be covered by the general control mechanism, a significant industrial user must file a written request for coverage that identifies its contact information, production processes, the types of wastes generated, the location for monitoring all wastes covered by the general control mechanism, any requests in accordance with 40 CFR 403.12(e)(2) for a monitoring waiver for a pollutant neither present nor expected to be present in the discharge, and any other information the Control Authority deems appropriate. A monitoring waiver for a pollutant neither present nor expected to be present in the discharge is not effective in the general control mechanism until after the Control Authority has provided written notice to the significant industrial user that such a waiver request has been granted in accordance with 40 CFR 403.12(e)(2). The Control Authority must retain a copy of the general control mechanism, documentation to support the Control Authority's determination that a specific significant industrial user meets the criteria in 40 CFR 403.8(f)(1)(iii)(A)(1) through (f)(1)(iii)(A)(5), and a copy of the significant industrial user's written request for coverage for 3 years after the expiration of the general control mechanism. A Control Authority may not control a significant industrial user through a general control mechanism where the facility is subject to production-based categorical pretreatment standards or categorical pretreatment standards expressed as mass of pollutant discharged per day, or for industrial users whose limits are based on the combined wastestream formula in 40 CFR 403.6(e). Both individual and general control mechanisms must, be enforceable and contain the minimum conditions described in 40 CFR 403.8(f)(1)(iii)(B)(1)-(6). Each pretreatment permit will include, where appropriate, conditions and limits which ensure that concentration and mass limit requirements under 40 CFR 403.6(c)(1)-(9), dilution prohibition requirements under 40 CFR 403.6(d) and combined wastestream formula requirements under 40 CFR 403.6(e)(1)-(4) are complied with;

4. Require the development of a compliance schedule by each industrial user for the installation of technology required to meet applicable pretreatment standards and requirements and the submission of all notices and self-monitoring reports from industrial users with pretreatment standards and requirements, including, but not limited to the reports required in 40 CFR 403.12;

5. Carry out all inspection, surveillance and monitoring procedures necessary to determine, independent of information supplied by industrial users, compliance or noncompliance with applicable pretreatment standards and requirements by industrial users. Representatives of the POTW shall be authorized to enter any premises of any industrial user in which a discharge source or treatment system is located or in which records are required to be kept under 40 CFR 403.12(o) to assure compliance with pretreatment standards. Such authority shall be at least as extensive as the authority provided under Section 308 of the Federal Act;

6. Obtain remedies for noncompliance by any industrial user with any pretreatment standard and requirement. All POTW's shall be able to seek injunctive relief for noncompliance by industrial users with pretreatment standards and requirements. All POTW's shall also have authority to seek or assess civil or criminal penalties in at least the amount of $1,000 a day for each violation by industrial users of pretreatment standards and requirements. Pretreatment requirements which will be enforced through the remedies set forth in this Subparagraph will include but not be limited to, the duty to allow or carry out inspections, entry, or monitoring activities; any rules, regulations or orders issued by the POTW; any requirements set forth in control mechanisms issued by the POTW; or any reporting requirements imposed by the POTW; or any reporting requirements imposed by the POTW or these regulations. The POTW shall have authority and procedures (after informal notice to the discharger) to immediately and effectively halt or prevent any discharge of pollutants to the POTW which reasonably appears to present an imminent endangerment to the health or welfare of persons. The POTW shall also have authority and procedures (which shall include notice to the affected industrial users and an opportunity to respond) to halt or prevent an endangerment to the environment or which threatens to interfere with the operation of the POTW. The EPD shall have the authority to take additional enforcement action when the EPD determines that the Control Authority's enforcement response to noncompliance by an industrial user is insufficient;

7. Comply with the confidentiality requirements set forth in 40 CFR 403.14.

(b) The Control Authority shall develop and implement an enforcement response plan which contains detailed procedures indicating how a POTW will investigate and respond to instances of industrial user noncompliance.
