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 Part 403.6(a)(4), whichever is later, existing CIUs subject to such pretreatment standards currently discharging to or scheduled to discharge to the city’s sanitary sewer system shall submit to the director a report which contains the information listed below.
At least ninety (90) days prior to commencement of discharge, new sources, and sources that become CIUs subsequent to the promulgation of an applicable categorical pretreatment standard shall submit to the director a report which contains the information listed below. A new source shall report the method of pretreatment it intends to use to meet the applicable pretreatment standards, an estimate of its anticipated flow, and an estimate of the quantity of pollutants to be discharged.
Users described above shall submit the following information:
2. Measurement of pollutants.
a. The user shall provide the information required in section 15.40.175(7);
b. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this paragraph.
c. 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 wastewater are mixed with the regulated wastewater prior to pretreatment, the city should measure the flows and concentrations necessary to allow the use of the combined wastestream formula (40 CFR Part 403.6(e)) to evaluate compliance with the pretreatment standards. Where an alternative concentration or mass limit has been calculated in accordance with 40 CFR Part 403.6(e) this adjusted limit along with supporting data shall be submitted to the city.
d. Sampling and analysis shall be performed in accordance with section 15.40.430.
e. The baseline monitoring 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 city’s sanitary sewer system.
3. Compliance Certification. A statement, reviewed and signed by the user’s authorized representative and certified by a qualified professional, indicating whether pretreatment standards and requirements are being met on a consistent basis, and, if not, whether additional operations and maintenance and/or pretreatment is required to meet the pretreatment standards and requirements.
4. Compliance Schedule. If additional pretreatment and/or operations and maintenance will be required to meet the pretreatment standards and requirements, the shortest schedule by which the user will provide such additional pretreatment and/or operations and maintenance must be provided. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard or requirement. A compliance schedule pursuant to this section must meet the requirements of section 15.40.320 of this chapter.
5. Signature and Report Certification. All baseline monitoring reports must be certified in accordance with section 15.40.180 of this chapter and signed by an authorized representative.
(Ord. 2481 §1 (part))
Within ninety (90) days following the date for final compliance with applicable pretreatment standards and requirements or, in the case of a new source, following commencement of discharge, any user subject to such pretreatment standards and requirements shall submit to the director a report containing the information described in sections 15.40.175(6)-(7) and 15.40.290(2). For users subject to equivalent mass or concentration limits established in accordance with the procedures in 40 CFR Part 403.6 (c), this report shall contain a reasonable measure of the user’s long-term production rate. For users subject to pretreatment standards and requirements 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 section 15.40.180. All sampling must be completed in conformance with section 15.40.430.
(Ord. 2481 §1 (part))
The director shall require a compliance schedule from each user for installation of technology required to meet a pretreatment standard or requirement, to install accidental spill and slug discharge prevention, or to implement personnel training.
1. Any compliance schedule must contain milestone 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 or requirements (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);
2. No increment referred to above shall exceed nine (9) months;
3. Within both fourteen (14) days of completion of a milestone in the compliance schedule and within fourteen (14) days of the final date for compliance, the user must submit a progress report to the director indicating whether or not the milestone or final compliance date was met, and if not, the reason for any delay, and the steps being taken by the user to return to the established schedule.
4. In no event shall more than nine (9) months elapse between such progress reports to the director.
(Ord. 2481 §1 (part))
1. Except as specified in section 15.40.330(3), all users operating under a wastewater discharge permit must, at a frequency determined by the director, submit no less than twice per year (July and January) reports indicating the nature, concentration of pollutants in the discharge which are limited by pretreatment standards or requirements, and the measured or estimated average and maximum daily flows for the reporting period. In cases where the pretreatment standard requires compliance with a BMP or pollution prevention alternative, the user must submit documentation required by the director or the pretreatment standard necessary to demonstrate the compliance status of the user.
2. The city may authorize a user subject to a categorical pretreatment standard to forgo sampling of a pollutant regulated by a categorical pretreatment standard if the user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is only present at background levels from intake water and without any increase in the pollutant due to activities of the user. This authorization is subject to the following conditions:
a. The waiver may be authorized where a pollutant is determined to be present solely due to sanitary wastewater discharged from the facility provided that the sanitary wastewater is not regulated by an applicable categorical pretreatment standard and otherwise includes no process wastewater.
b. The monitoring waiver is valid only for the duration of the effective period of the wastewater discharge permit, but in no case longer than five (5) years. The user must submit a new request for the waiver before the waiver can be granted for each subsequent wastewater discharge permit.
c. In making a demonstration that a pollutant is not present, the user must provide data from at least one sampling of the facility’s process wastewater prior to any treatment present at the facility that is representative of all wastewater from all processes.
d. The request for a monitoring waiver must be signed by an authorized representative, and include the certification statement in section 15.40.180.
e. Non-detectable sample results may only be used as a demonstration that a pollutant is not present if an approved method with the lowest minimum detection level for that pollutant was used in the analysis.
f. Any grant of the monitoring waiver by the director must be included as a condition in the user’s wastewater discharge permit. The reasons supporting the waiver and any information submitted by the user in its request for a waiver must be maintained by the director for three (3) years after expiration of the waiver.
g. Upon approval of the of the monitoring waiver and revision of the user’s permit by the director, the user must certify on each report with the statement in section 15.40.180 that there has been no increase in the pollutant in its wastestream due to activities of the user.
h. In the event the waived pollutant is found to be present or is expected to be present because of changes that occur in the user’s operations, the user must immediately comply with the monitoring requirements of section 15.40.430, or other more frequent monitoring requirements imposed by the director; and notify the director.
i. This provision does not supersede certification processes and requirements established in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.
3. The city may reduce the requirement for periodic compliance reports to a required to report no less frequently than once per year, unless required more frequently in the pretreatment standard or by USEPA, State Water Resources Control Board, or Central Valley Regional Water Quality Control Board, where the user’s total categorical wastewater flow does not exceed any of the following:
a. 0.01 percent of the design dry weather hydraulic capacity of the water pollution control plant or five thousand (5,000) gallons per day, whichever is smaller, as measured by a continuous effluent flow monitoring device unless the user discharges in batches;
b. 0.01 percent of the design dry weather organic treatment capacity of the water pollution control plant; and
c. 0.01 percent of the maximum allowable headworks loading for any pollutant regulated by the applicable categorical pretreatment standard for which approved local limits were developed by the city in accordance with section 15.40.024.
Reduced reporting is not available to users that have in the last two (2) years been in significant noncompliance. In addition, reduced reporting is not available to a user with daily flow rates, production levels, or pollutant levels that vary so significantly that, in the opinion of the director, decreasing the reporting requirement for this user would result in data that are not representative of conditions occurring during the reporting period.
4. All periodic/self-monitoring compliance reports must be signed by an authorized representative and certified in accordance with section 15.40.180 of this chapter.
5. 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.
6. If a user subject to the reporting requirements in this section monitors any pollutant more frequently than required by the director, using the procedures prescribed in section 15.40.430, the results of this monitoring shall be included in the report.
(Ord. 2481 §1 (part))
Users shall notify the director in writing of any planned changes to the user’s operations or system which might alter the nature, quality, or volume of its wastewater at least ninety (90) days before the change.
1. The director may require the user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a wastewater discharge permit application under section 15.40.175.
3. For purposes of this requirement, changes include but are not limited to, flow increase of twenty (20) percent or greater and the discharge of any previously unreported pollutants.
(Ord. 2481 §1 (part))
In the case of any discharge of a non-routine or episodic nature, including, but not limited to, accidental discharges, spills, a non-customary batch discharge, or a slug load, users (whether or not such users are industrial users and whether or not such users are required to possess a waste discharge permit) shall immediately telephone and notify the director 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.
Within five (5) days following such a discharge, the user shall submit a detailed written report to the director 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 city’s sanitary sewer system, 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 chapter.
(Ord. 2481 §1 (part))
1. All users shall notify in writing the director, State Water Resources Control Board, Central Valley Regional Water Quality Control Board, California Department of Toxic Substances Control, and USEPA Regional Waste Management Division Director of any discharge which, if otherwise disposed of would be considered 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 USEPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the user discharges more than one hundred (100) kilograms of such waste per calendar month to the city’s sanitary sewer system, the notification shall also include the following information to the extent such information is known or readily available to the user: an identification of the hazardous constituents contained in the waste, an estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month, and an estimation of the mass of constituents in the wastestream expected to be discharged during the following twelve (12) months. Notification shall take place within one hundred and eighty (180) days after the discharge commences. Any notification under this section need be submitted only once for each hazardous waste discharged; however, notification of changed circumstances or changed discharges must be submitted under section 15.40.340.
2. In the event new regulations are promulgated pursuant to section 3001 of the Resource Conservation and Recovery Act of 1976 (Pub. Law 94-580, 90 Stat. 2806, 42 United States Code section 6921), identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, industrial users shall notify in writing the director, State Water Resources Control Board, Central Valley Regional Water Quality Control Board, California Department of Toxic Substances Control, and USEPA Waste Management Division Director of the discharge of such substance within ninety (90) days of the effective date of such regulation.
3. In the event of any notification made under this section, the user shall certify 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.
