3.07.020 Baseline monitoring reports.
All users that become subject to new or revised categorical pretreatment standards are required to comply with the following reporting requirements even if they have been designated as nonsignificant categorical industrial users.
A. Within either 180 days after the effective date of a categorical pretreatment standard, or the final administrative decision on a category determination under 40 CFR 403.6(a)(4), whichever is later, existing categorical industrial users currently discharging to or scheduled to discharge to the POTW shall submit to the General Manager, or his or her designee, a report which contains the information listed in subsection (B) of this section. At least 90 days prior to commencement of their discharge, new sources, and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical standard, shall submit to the General Manager, or his or her designee, a report which contains the information listed in subsection (B) of this section. A new source shall report the method of pretreatment it intends to use to meet applicable categorical standards. A new source also shall give estimates of its anticipated flow and quantity of pollutants to be discharged.
B. Users described above shall submit the information set forth below.
1. All information required in MCWDC 3.06.020.
2. Measurement of Pollutants.
a. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this paragraph;
b. Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment, the user should measure the flows and concentrations necessary to allow use of the combined waste stream formula in 40 CFR 403.6(e) to evaluate compliance with the pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e) this adjusted limit along with supporting data shall be submitted to the control authority;
c. Sampling and analysis shall be performed in accordance with MCWDC 3.07.120;
d. The General Manager, or his or her designee, may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures;
e. The baseline report shall indicate the time, date and place of sampling and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW.
3. Compliance 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.
4. 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 must be provided. 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 MCWDC 3.07.030.
5. Signature and Report Certification. All baseline monitoring reports must be certified in accordance with MCWDC 3.07.150 and signed by an authorized representative as defined in this code.
3.07.030 Compliance schedule progress reports.
The following conditions shall apply to the compliance schedule required by MCWDC 3.07.020(B)(4):
A. The schedule shall contain progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable pretreatment standards (such events include, but are not limited to, hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, and beginning and conducting routine operation);
B. No increment referred to above shall exceed nine months;
C. The user shall submit a progress report to the General Manager, or his or her designee, no later than 14 days following each date in the schedule and the final date of compliance including, as a minimum, whether or not it complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the user to return to the established schedule; and
D. In no event shall more than nine months elapse between such progress reports to the General Manager, or his or her designee.
3.07.040 Reports on compliance with categorical pretreatment standard deadline.
Within 90 days following the date for final compliance with applicable categorical pretreatment standards, or in the case of a new source following commencement of the introduction of wastewater into the POTW, any user subject to such pretreatment standards and requirements shall submit to the General Manager, or his or her designee, a report containing the information described in MCWDC 3.06.020(F) and (G) and 3.07.020(B)(2). For users subject to equivalent mass or concentration limits established in accordance with the procedures in MCWDC 3.05.060, this report shall contain a reasonable measure of the user’s long term production rate. For all other users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user’s actual production during the appropriate sampling period. All compliance reports must be signed and certified in accordance with MCWDC 3.07.150. All sampling will be done in conformance with MCWDC 3.07.120.
3.07.050 Periodic compliance reports.
A. All users must submit twice per year, June 30th and December 31st, reports indicating the nature, concentration of pollutants in the discharge which are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. In cases where the pretreatment standard requires compliance with a best management practice (BMP) or pollution prevention alternative, the user must submit documentation required by the District or the pretreatment standard necessary to determine the compliance status of the user.
B. All wastewater samples must be representative of the user’s discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
C. If a user subject to the reporting requirement in this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the General Manager, or his or her designee, using the procedures prescribed in MCWDC 3.07.120, the results of this monitoring shall be included in the report.
3.07.060 Reports of changed conditions.
Each user must notify the General Manager, or his or her designee, of any significant changes to the user’s operations or system which might alter the nature, quality, or volume of its wastewater at least 60 days before the change.
A. The General Manager, or his or her designee, may require the user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of an individual wastewater discharge permit application under Chapter 3.06 MCWDC.
B. The General Manager, or his or her designee, may issue a new individual wastewater discharge permit or modify an existing individual wastewater discharge permit in response to changed conditions or anticipated changed conditions.
3.07.070 Reports of potential problems.
A. In the case of any discharge, including, but not limited to, accidental discharges, discharges of a nonroutine, episodic nature, a noncustomary batch discharge, a slug discharge or slug load, that might cause potential problems for the POTW, the user shall immediately telephone and notify the General Manager, or his or her designee, of the incident. This notification shall include the location of the 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, unless waived by the General Manager, or his or her designee, 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 might 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, penalties, or other liability which may be imposed pursuant to this code.
C. A notice shall be permanently posted on the user’s bulletin board or other prominent place advising employees who to call in the event of a discharge described in subsection (A) of this section. Employers shall ensure that all employees who could cause such a discharge to occur are advised of the emergency notification procedure.
D. Significant industrial users are required to notify the General Manager, or his or her designee, immediately of any changes at its facility affecting the potential for a slug discharge.
3.07.080 Reports from unpermitted users.
All users not required to obtain an individual wastewater discharge permit shall provide appropriate reports to the General Manager, or his or her designee, as the General Manager, or his or her designee, may require.
3.07.090 Notice of violation/repeat sampling and reporting.
If sampling performed by a user indicates a violation, the user must notify the General Manager, or his or her designee, within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the General Manager, or his or her designee, within 30 days after becoming aware of the violation. Resampling by the industrial user is not required if the District performs sampling at the user’s facility at least once a month, or if the District performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the District receives the results of this sampling, or if the District has performed the sampling and analysis in lieu of the industrial user.
3.07.100 Notification of the discharge of hazardous waste.
A. This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this code, a permit issued thereunder, or any applicable federal or state law.
B. Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR Part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the user discharges more than 100 kilograms of such waste per calendar month to the POTW, the notification also shall 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 conditions must be submitted under MCWDC 3.07.060. The notification requirement in this section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of this chapter.
C. Dischargers are exempt from the requirements of subsection (A) of this section 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). Discharge of more than 15 kilograms of nonacute 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 user discharges more than such quantities of any hazardous waste do not require additional notification.
D. In the case of any new regulations under Section 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the user must notify the General Manager or his or her designee, 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.
E. 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.
3.07.110 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 Part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the EPA determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the General Manager, or his or her designee, or other parties approved by EPA.
3.07.120 Sample collection.
Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report, based on data that is representative of conditions occurring during the reporting period.
A. Except as indicated in subsections (B) and (C) of this section, the user must collect wastewater samples using 24-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the General Manager, or his or her designee. Where time-proportional composite sampling or grab sampling is authorized by the District, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the District, as appropriate. In addition, grab samples may be required to show compliance with instantaneous limits.
B. Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.
C. For sampling required in support of baseline monitoring and 90-day compliance reports required in MCWDC 3.07.020 and 3.07.040 (40 CFR 403.12(b) and (d)), a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the General Manager, or his or her designee, may authorize a lower minimum. For the reports required by MCWDC 3.07.050 (40 CFR 403.12(e) and 403.12(h)), the industrial user is required to collect the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.
3.07.130 Date of receipt of reports.
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 United States Postal Service, the date of receipt of the report shall govern.
3.07.140 Record keeping.
Users subject to the reporting requirements of this code shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this code, any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements, and documentation associated with best management practices established under this code. Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. 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 the user or the District, or where the user has been specifically notified of a longer retention period by the General Manager, or his or her designee.
3.07.150 Certification statements.
A. Certification of Permit Applications, User Reports and Initial Monitoring Waiver. The following certification statement is required to be signed and submitted by users submitting permit applications in accordance with Chapter 3.06 MCWDC; users submitting baseline monitoring reports; users submitting reports on compliance with the categorical pretreatment standard deadlines; users submitting periodic compliance reports required by this code; and a statement must be signed by an authorized representative:
