7.04.500 Industrial Waste – Monitoring and Reporting.
A. Discharge Reports.
1. Every industrial user shall file a periodic discharge report at such intervals as are designated by the District. The District may also require any other users discharging or proposing to discharge into the treatment system to file such periodic reports. Those dischargers who have successfully eliminated their discharges and are, effectively, zero-dischargers must certify each year that they are still not discharging by submitting a statement verifying their zero-discharge status every year before the end of January. The user certifying zero-discharge must meet all of the conditions for zero-discharge:
a. No discharge of process wastewater to the sanitary sewer is permitted.
b. The industrial user is required to notify the District of any changes in operation resulting in a potential for discharge immediately upon discovery.
c. An initial and annual certification of that no discharge has occurred is required at the end of January each year.
d. The District may inspect the industrial users’ facilities as necessary, without notice, to assess and assure compliance with the “no discharge requirement.”
e. The industrial user must comply with the Resource Conservation and Recovery Act (RCRA) and State hazardous waste and air regulations regarding the proper disposal of hazardous waste. Alternative waste disposal other than sanitary sewer disposal of process wastewater must not adversely impact any other environmental media such as air, any water bodies, and/or soil.
2. The discharge report shall include, but, in the discretion of the District, shall not be limited to, nature or process, volume, rates of flow, mass emission rate, production quantities, hours of operation, concentrations of controlled pollutants, or other information which relates to the generation of waste. Such reports may also include the chemical constituents and quantity of liquid materials stored on site even though they are not normally discharged. Discharge reports shall be signed by the owner or an executive officer of the industrial user, company or corporation. In addition to discharge reports, the District may require information in the form of industrial discharge permit applications, self-monitoring reports and cleaning receipts or contracts.
B. Records and Monitoring.
1. All industrial users who discharge or propose to discharge wastewaters to the wastewater treatment system shall maintain such records of production and related factors, effluent flows and pollutant amounts or concentrations that are necessary to demonstrate compliance with the requirements of this chapter and any applicable State or Federal pretreatment standards or requirements.
2. Industrial users subject to pretreatment reporting requirements shall maintain records of all information resulting from any monitoring activities. Such records shall include for all samples:
a. The date, exact place, method, and time of sampling, and the names of the person or persons taking the samples;
b. The dates analyses were performed;
c. Who performed the analyses;
d. The analytical techniques/methods used; and
e. The results of such analyses.
3. Industrial users shall retain for a minimum of three years any records of monitoring activities and results and shall make such records available for inspection and copying by the SWQCB, the USEPA, the City or County when requested. Records shall be retained for a period longer than three years in the case of unresolved litigation, or upon request of the EPA, SWQCB, the City or the District.
4. Such records shall be made upon request by the District. All such records relating to compliance with pretreatment standards shall be made available to officials of the U.S. Environmental Protection Agency upon demand. A summary of such data indicating the industrial user’s compliance with this chapter may be required quarterly for submittal to the District.
5. The owner or operator of any premises or facility discharging industrial wastes into the system shall install, at his own cost and expense, suitable monitoring equipment to facilitate the accurate observation, sampling and measurement of wastes. Such equipment shall be maintained in proper working order and kept safe and accessible at all times.
6. The monitoring equipment shall be located and maintained on the industrial user’s premises outside the building. When such a location would be impractical or cause undue hardship on the user, the District may allow such facility to be constructed in the public street or sidewalk area, with the approval of the public agency having jurisdiction over such street or sidewalk and located so that it will not be obstructed by public utilities, landscaping or parked vehicles.
7. When more than one user can discharge into a common sewer, the District may require installation of separate monitoring equipment for each user. When there is a significant difference in wastewater constituents and characteristics produced by different operations of a single user, the District may require that separate monitoring facilities be installed for each separate discharge.
8. Whether constructed on public or private property, the monitoring facilities shall be constructed in accordance with the District’s requirements and all applicable construction standards and specifications. Engineered plans may be required, if so specified by the District Engineer.
C. Inspection, Sampling and Analysis.
1. Compliance Determination. Compliance determinations with respect to Section 7.04.310, prohibitions and limitations, may be made on the basis of either instantaneous grab samples or composite samples of wastewater. Composite samples may be taken over a twenty-four-hour period, or over a longer or shorter time span, as determined necessary by the District to meet the needs of specific circumstances.
2.
a. Analysis of Industrial Wastewater. Collection and preservation of industrial wastewater samples shall be in accordance with the techniques approved by the Environmental Protection Agency. All analyses shall be performed in accordance with procedures contained in 40 CFR Part 136 and amendments thereto or with any other test procedure approved by the EPA administrator.
b. Where 40 CFR Part 136 does not include sampling and analytical techniques for the pollutants in question, sampling and analyses shall be performed using validated analytical methods as prescribed in the most current edition of Standard Methods for the Examination of Water and Wastewater, as published jointly by the American Public Health Association, the American Water Works Association and the Water Pollutant Control Federation.
3. Sampling Frequency. Sampling of industrial wastewater for the purpose of compliance determination with respect to Section 7.04.310, prohibitions and limitations, will be done at such intervals as the District may designate. However, it is the intention of the District to conduct compliance sampling or cause such sampling to be conducted for all industrial users at least once a year. Any authorized officer or employee of the District or the City may enter and inspect at any reasonable time any part of the sewer system of the District. The right of entry and inspection shall extend to public streets, easements and property within which the system is located. Additionally, the District or City shall be permitted, as appropriate, to enter onto private property to inspect industrial waste dischargers. The right of inspection shall include on-site inspection of pretreatment and sewer facilities, observation, measurement, sampling, testing, and access to (with the right to copy) all pertinent compliance records located on the premises of the industrial user, including receipts or proof of cleaning.
D. Reports Required by Federal Law. Every industrial user shall submit to the District all required reports as well as those reports required to be submitted to the control authority under the Code of Federal Regulations, Title 40, Section 403.12 (40 CFR Section 403.12), as now in effect or as hereafter amended. These reports shall be submitted under the same circumstances and at the same times and shall include the same information, as required by that section of the Code of Federal Regulations. Reports shall be signed by the owner or an executive officer of that industrial user company or corporation. At the discretion of the District, such reports may be combined with other reports required by this code, when timely and appropriate.
Industrial users whose reports show noncompliance with local or national pretreatment standards or limits, or who have exceeded the local limits or national pretreatment standards as a result of the District sampling, shall be sampled again by the District within thirty days of that violation. If the results of the second sampling reveal continued noncompliance, then the District will subsequently continue to sample at least every thirty days until compliance by the user is achieved. All subsequent sampling costs from the District sampling shall be borne by the user. Payment of sampling charges shall be paid to the District within ninety days of notification. The District shall revoke the user’s permit if payment is not made within the specified time.
The District shall publish each year a list of those users who were in significant noncompliance of District and national pretreatment standards. (Ord. 103 §7, 2002; Ord. 85 §6, 1995; Ord. 72 §1, 1991; Ord. 64 §3; Ord. 37 §3, 1983; Ord. 3 §6.10, 1973)
