At least 90 days prior to commencement of their discharge, new sources, and sources that become users subsequent to the promulgation of an applicable categorical standard, shall be required to submit to the City a report which contains the information listed in this division. A new source shall also be required to report the method of pretreatment it intends to use to meet applicable pretreatment standards. A new source shall also give estimates of its anticipated flow and quantity of pollutants discharged. (b) The user shall submit the information required by this section, including: (1) Identifying information. The name and address of the facility, including the name of the operator and owners. (2) Wastewater discharge permits. A list of any environmental control wastewater discharge permits held by or for the facility. (3) Description of operations. A brief description of the nature, average rate of production, and standard industrial classifications of the operation(s) carried out by such user. This description should include a schematic process diagram which indicates points of discharge to the POTW from the regulated processes. (4) Flow measurement. Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary, to allow use of the combined waste stream formula set out in 40 CFR 403.6(e), as amended. (5) Measurement of pollutants. a. identify the categorical pretreatment standards applicable to each regulated process. b. submit the results of sampling and analysis identifying the nature and concentration (and/or mass, where required by the standard or by the City) of regulated pollutants in the discharge from each regulated process. Instantaneous, daily maximum and long-term average concentrations (or mass, where required) shall be reported. The sample shall be representative of daily operations and shall be analyzed in accordance with procedures set out in this division. c. sampling must be performed in accordance with procedures set out in this division. d. at the discretion of the Director, the User may be granted a waiver if the user can demonstrate to the Director's satisfaction that a particular pollutant is not present in its process waste stream or is only present in background levels in the intake water. (6) Certification. A statement reviewed by the user's authorized representative 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 (O&M) and/or additional pretreatment is required to meet the pretreatment standards and requirements. (7) Compliance schedule. If additional pretreatment and/or O&M will be required to meet the pretreatment standards, the shortest schedule by which the user will provide such additional pretreatment and/or O&M. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. A compliance schedule pursuant to this section must meet the requirements set out in 40 CFR 403.12(B)(7) and (C), as amended. (8) Baseline monitoring reports.

§ 47-336. - Reports of potential problems. (a) In the case of any discharge including, but not limited to, accidental discharges, discharges of a non-routine, episodic nature, a non-customary batch discharge, or a slug load which may cause potential problems for the POTW (including a violation of the prohibited discharge standards in this chapter), it is the responsibility of the user to immediately telephone and notify the City of the incident. This notification shall include the location of discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user. (b) Within five days following such discharge, the user shall submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this chapter. (c) Failure to notify the City of potential problem discharges shall be deemed a separate violation of this chapter. (d) A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of a discharge described in Paragraph (a) above. Employers shall ensure that all employees, who may cause or suffer such a discharge to occur, are advised of the emergency notification procedure. (Code 1980, § 41-6.6; Ord. No. 19830, § 1, 9-29-92; Ord. No. 27272, § 4, 1-31-23)

Oklahoma City Municipal Code § 47-337 Reports from significant non-categorical users and nonsignificant users.

§ 47-337. - Reports from significant non-categorical users and nonsignificant users. (a) The control authority shall require appropriate reporting from those users with discharges that are not subject to categorical pretreatment standards. Significant non-categorical users shall submit to the control authority at least once every six months (on dates specified by the control authority) a description of the nature, concentration, and flow of the pollutants required to be reported by the control authority. These reports shall be based on sampling and analysis performed in the period covered by the report, and performed in accordance with the techniques described in 40 CFR 136, and amendments thereto. Where 40 CFR 136, does not contain sampling or analytical techniques for the pollutant in question, or where the Administrator determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the City or other persons, approved by the Administrator. This sampling and analysis may be performed by the control authority in lieu of the significant non-categorical user. Where the City itself collects all the information required for the report, the non-categorical significant user will not be required to submit the report. (b) All users not subject to categorical pretreatment standards and not required to obtain a wastewater discharge permit shall provide appropriate reports to the City as the Director may require. (Code 1980, § 41-6.7; Ord. No. 19830, § 1, 9-29-92; Ord. No. 22053, § 3, 10-8-02; Ord. No. 27272, § 4, 1-31-23)

Oklahoma City Municipal Code § 47-338 Notice of violation/repeat sampling and reporting.

§ 47-338. - Notice of violation/repeat sampling and reporting. If sampling performed by an industrial user indicates a violation, the industrial user must notify the City within 24 hours of becoming aware of the violation. The industrial user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the control authority within 30 days after becoming aware of the violation. The industrial user is not required to resample if the City performs monitoring at the industrial user's site at least once a month, or if the City performs sampling between the industrial user's initial sampling and when the industrial user receives the results of this sampling. (Code 1980, § 41-6.8; Ord. No. 19830, § 1, 9-29-92; Ord. No. 22053, § 3, 10-8-02)

Oklahoma City Municipal Code § 47-339 Notification of discharge of hazardous waste.

§ 47-339. - Notification of discharge of hazardous waste. (a) Any user who commences the discharge of hazardous waste shall notify the City, the EPA Regional Waste Management Division Director and state hazardous waste authorities (ODEQ) in writing of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR 261, as amended. Such notification must include the name of the hazardous waste as set forth in 40 CFR 261, as amended, the EPA hazardous waste number, and the type of discharge (continuous, batch or other). If the user discharges more than ten kilograms of such waste per calendar month to the City, the notification shall also contain the following information to the extent such information is known and readily available to the user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the waste stream discharged during that calendar month, and an estimation of the mass of constituents in the waste stream expected to be discharged during the following 12 months. All notifications must take place no later than 180 days after the discharge commences. Any notification under this paragraph need be submitted only once for each hazardous waste discharged. However, notifications of changed discharges must be submitted to the Director. The notification requirement in this section does not apply to pollutants already reported under the self-monitoring requirements of this chapter. (b) Dischargers are exempt from the requirements of this article during a calendar month in which they discharge no more than 15 kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), as amended. Discharge of more than 15 kilograms of non-acute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the industrial user discharges more than such quantities of any hazardous waste do not require additional notification. (c) In the case of any new regulations under § 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the user must notify the City, the EPA Regional Waste Management Waste Division Director and state hazardous waste authorities of the discharge of such substance within 90 days of the effective date of such regulations. (d) In the case of any notification made under this section, the user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical. (Code 1980, § 41-6.9; Ord. No. 19830, § 1, 9-29-92; Ord. No. 22053, § 3, 10-8-02; Ord. No. 27272, § 4, 1-31-23)

Oklahoma City Municipal Code § 47-340 Analytical requirements.

§ 47-340. - Analytical requirements. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report, shall be performed in accordance with the techniques prescribed in 40 CFR 136, as amended, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR 136, as amended, does not contain sampling or analytical techniques for the pollutant in question, sampling and analyses must be performed in accordance with procedures approved by the EPA. All analytical results must be reported to the Control Authority. (Code 1980, § 41-6.10; Ord. No. 19830, § 1, 9-29-92; Ord. No. 24155, § 4, 10-19-10)

Oklahoma City Municipal Code § 47-341 Sample collection.

§ 47-341. - Sample collection. (a) Except in Subsection (b) below, where flow is sufficient, wastewater compliance samples shall be a composite sample of at least four grab samples of equal proportion taken at equal time intervals during a users normal production day. The Director may use production records and flow data to establish a user's normal production day, and may require grab samples to be taken at greater intervals to prepare a composite sample. An instantaneous grab sample shall be used to determine compliance on batch or intermittent discharge. The 30-Day average limit shall apply to batch or intermittent discharge in determining user compliance. (b) Samples for oil and grease, temperature, pH, cyanide, phenols, toxicity, sulfides and volatile organic chemicals must be obtained using grab collection techniques. (Code 1980, § 41-6.11; Ord. No. 19830, § 1, 9-29-92; Ord. No. 20916, § 10, 10-21-97; Ord. No. 24155, § 4, 10-19-10)

Oklahoma City Municipal Code § 47-342 Determination of noncompliance by use of grab sample.

§ 47-342. - Determination of noncompliance by use of grab sample. The Director may use a grab sample(s) to determine noncompliance with pretreatment standards. (Code 1980, § 41-6.12; Ord. No. 19830, § 1, 9-29-92)

Oklahoma City Municipal Code § 47-343 Date of submittal.

§ 47-343. - Date of submittal. For purposes of this division, written reports will be deemed to have been submitted on the date postmarked. For reports which are not mailed, postage prepaid, into a mail facility serviced by the U.S. postal service, the date of receipt of the report shall govern. (Code 1980, § 41-6.13; Ord. No. 19830, § 1, 9-29-92)

Oklahoma City Municipal Code § 47-344 Recordkeeping.

§ 47-344. - Recordkeeping. (a) Industrial users shall retain and make available for inspection and copying all records and information required to be retained under this chapter. These records shall remain available for a period of at least three years. This period shall be automatically extended for the duration of any litigation concerning compliance with this article, or where the industrial user has been specifically notified of a longer retention period by the Director. (b) Provision governing fraud and false statements. The reports and other documents required to be submitted or maintained under this chapter shall be subject to: (1) the provisions of 18 USC 1001, as amended, relating to fraud and false statements; (2) the provisions of § 309(c)(4) of the Act, as amended, governing false statements, representation or certification; and (3) the provisions of § 309(c)(6) of the Act, as amended, regarding responsible corporate officers.
