The approval authority must be notified of new pollutants or changes in discharge, including type, volume and character.
(B) (1) The POTW’s must maintain general program files that document program development and implementation activities that are not industrial user specific. Pretreatment programs are required to maintain local limits records during at least the effective dates of the local limits and for three (3) years after. The type of POTW records maintained include, but are not limited to:
(a) Legal authority;
(b) Program procedures;
(c) Program approval and modifications;
(d) List of significant industrial users;
(e) Copy of POTW NPDES permits;
(f) Local limits development;
(g) Correspondence to and from EPA/state;
(h) Annual reports to the approval authority;
(i) industrial user compliance and permitting records.
(2) The POTW is required to submit annual reports to the approval authority documenting program status and activities performed during the previous year.
(C) The POTW is required to maintain records resulting from monitoring in a readily accessible manner for at least three (3) years. All required pretreatment activities must be recorded and the documents maintained, including, but not limited to:
(1) Industrial waste questionnaires;
(2) Permit applications, permits and fact sheets;
(3) Inspection reports;
(4) Industrial user reports;
(5) Monitoring data (including laboratory reports);
(6) Required plans such as slug control, sludge management and pollution preventer;
(7) Compliance and enforcement activities;
(8) Phone logs and meeting summaries.
(D) Self-monitoring compliance reporting. In accordance with 40 CFR 403.12(9), any significant industrial user subject to a categorical pretreatment standard, after the compliance date of such pretreatment standard, or, in the case of a new source, after commencement of the discharge into the POTW, shall submit to the control authority every six (6) months during the months of June and December, unless required more frequently in the pretreatment standard or by the control authority, a report indicating, at a minimum, the nature and concentration of pollutants in the effluent which are limited by either the pretreatment standards or the discharge permit. The report shall also include the chain-of-custody (COC) forms, field data and any other information required by the control authority. In addition, this report shall include a record of all measured or estimated average daily flows which during the reporting period, exceeded the average daily flow. At the discretion of the control authority, and in consideration of such factors as local high or low rates, holidays, budget cycles, etc., the control authority may agree to alter the months during which the reports are to bo submitted. All periodic compliance reports must be signed and certified in accordance with 40 CFR 403.12 and § 31.376.
(E) Baseline monitoring report (BMR). A baseline monitoring report must be submitted to the control authority by all industrial users at least ninety (90) days prior to the initiation of discharge to the sanitary sewer. The BMR shall contain, at a minimum, the following:
(1) Production data, a process description, SIC code, list of raw materials, chemicals used in process, chemicals used in cleanup, final product, pretreatment industrial category (if applicable and a schematic which indicates points of discharge to the sewer system;
(2) Identifying information to include name of facility contact person, address of facility, owner(s), and any other permits held by the facility;
(3) Wastewater characteristics: Total plant flow, types of discharges (batch, continuous, or other), average and maximum flows from each process;
(4) Name, nature and concentration of pollutants discharged to the public sewer system: analytical results for all pollutants that are regulated by this chapter, state, and/or applicable federal pretreatment standard and sample type and location. All analyses must conform with 40 CFR Part 136 and amendments thereto;
(5) Information concerning all pretreatment equipment used to treat the facility's discharge; and
(6) Compliance certification. A statement, reviewed by the user's authorized representative as defined in § 31.301 and certified by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance and/or additional pretreatment is required to meet the pretreatment standards and requirements. See § 52.58(C).
(F) Documentation associated with best management practices compliance must be maintained for three (3) years.
(G) The Murray Sewer System and those industrial users discharging into the Murray POTW must maintain the reporting requirements for the POTW and industrial users according to 40 CFR 403.12, applicable state laws and regulations and City of Murray Ordinance Chapter 52 Sewers.
