Ventura County Municipal Code Art. 16 Industrial Wastewater Monitoring & Reporting

A. All industrial users discharging or proposing to discharge industrial wastewater to the County's sewerage system shall maintain records of its raw materials and usage, processes, effluent flows, pollutant concentrations and related factors. These records shall be necessary to demonstrate compliance with the requirements of this ordinance and any applicable Federal or State pretreatment standards. Any industrial user subject to the reporting requirements of this ordinance shall be required to retain for a minimum of three years any records of monitoring activities and results. This period of retention shall be extended during the course of any unresolved litigation regarding the industrial user or POTW or when requested by the Airport Administrator or the approval authority.

B. All such records relating to compliance with pretreatment standards shall be made available for inspection and copying at the company facility or, if located elsewhere, at the other location to officials of the EPA, Approval Authority and the Airports Administrator. (Federal Pretreatment Regulations 40 CFR 403.12 (o)(2)). (See Section 6512-2(B)).

C. The owner and/or occupant of any premises of facility discharging industrial wastewater into the County's sewerage system shall install at its or their own expense suitable monitoring equipment as may be required by this ordinance to facilitate the accurate observation, sampling, and measurement of regulated constituents. Such equipment shall be maintained in proper working order and kept safe and accessible at all times.

D. If the Airports Administrator requires or the owner or operator chooses to install a flow meter, the flow meter must be calibrated every six months and a photocopy of the calibration must be sent to the County. The calibration must be performed by one of the following: 1) the manufacturer; or 2) a qualified Civil Engineer. Flow charts are to be held by the user for a minimum of three years and made available to the County upon request. Totalizer readings shall be recorded daily and every month a report shall be submitted to the County showing total daily flows and total monthly flow.

E. All industrial users required to periodically sample and analyze their wastewater shall use sampling methods and sampling locations approved by the Airports Administrator. For each sample collected and analyzed the user shall maintain a record of:

1. The date, exact place, method and time of sampling and the names of the person or persons taking samples;

2. The dates and analysis where performed;

3. Who performed the analyses;

4. The analytical techniques/methods used;

5. The results of such analyses.

F. Whether constructed on public or private property, the approved sampling point shall be constructed in accordance with the County's requirements. An industry may request approval from the County for sampling wells installed prior to the effective date of this ordinance, which meet the design and accessibility requirements for sampling purposes.

A. Sampling well(s) of a design approved by the Airports Administrator shall be furnished and installed by designated industrial user to facilitate inspection, sampling and flow measurements. The sampling well(s) shall be located in an accessible location and the location shall be designated by the Airports Administrator.

B. Unrestricted access to the sampling well(s) shall be provided to authorized personnel of the County at all times.

A. Compliance determinations shall be made by the Airports Administrator with respect to Section 6513-1 and 6513-2 on the basis of either instantaneous grab or composite sampling of the wastewater. Grab samples may be taken as deemed necessary by the Airports Administrator to meet the needs of the specific circumstances. If routine grab or composite sampling reveals non-compliance by the discharger with the mass emission rates or conditions specified in the user's permit, then the user shall pay to the County fees as specified in the Rent & Fee Resolution and may be assessed all other costs incurred during the subsequent evaluation period for sampling and analysis, including labor, equipment, materials and overhead.

B. All analyses shall be performed in accordance with procedures established pursuant to Section 304(g) et seq. of the Federal Clean Water Act and contained in 40 CFR 136 and amendments thereto.

C. Sampling of industrial wastewater and wastes for the purpose of compliance determination shall be conducted at intervals specified by the Airports Administrator. However, it is the intention of the Airports Administrator to conduct compliance sampling for all industrial users at least once per year, for the constituents set forth in the user's industrial wastewater discharge permit.

A. All industrial users required to do so by the Airports Administrator shall monitor and report on the quantity and quality of their industrial wastewater discharge. The items to be included in the report and the frequency with which this report shall be submitted to the Airports Administrator will be detailed in the user's industrial wastewater discharge permit. The frequency of self-monitoring and reporting for those industrial dischargers not regulated by Federal pretreatment regulations will be based on the following factors:

1. The effect of the wastewater on the County's sewerage system;

2. The degree of toxic material which may pass through the treatment plant;

3. The quantity, nature, and type of the industrial wastewater discharge;

4. The extent to which the discharge could contribute to violation of the County's NPDES permit.

B. All reports submitted by the industrial user shall be required to be signed by an authorized representative of the user.

C. These reports shall be subject to the provisions of 18 U.S.C. Section 1001 relating to false statements and fraud and the provisions of Section 309(c)(2) of the Clean Water Act governing false statements.

D. Each self-monitoring report and all reports as required within this Article shall contain the following completed declaration:

"I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

E. The following reports will be required pursuant to promulgation of Section 307 et seq. of the Clean Water Act and the establishment of any pretreatment standards and regulations:

1. One hundred and eighty (180) days after the promulgation of pretreatment standards all existing industries subject to such standards shall be required to submit to the County a report containing:

a. The name and address of the user;

b. The location of the discharge;

c. The nature, average production rate, and standard industrial classification of the operations carried out by such user;

d. The average and maximum flow of the discharge in million gallons per day;

e. The nature and concentration of pollutants in the discharge from each regulated process and identification of applicable pretreatment standards. The concentration shall be reported as a maximum or average as provided for in applicable pretreatment standards;

f. A statement reviewed by an authorized representative of the industrial user and certified by a qualified professional indicating whether the pretreatment standards are being met on a consistent basis and if not, whether operation and maintenance improvements or additional pretreatment is required for compliance;

g. If additional pretreatment or operation and maintenance improvements are required the shortest schedule by which such operation or maintenance improvements or additional pretreatment will be completed. The completion date submitted shall not be later than the compliance date established in the applicable pretreatment standard.

2. New sources and sources that become industrial users subsequent to the promulgation of applicable categorical standards shall be required to submit to the Airports Administrator the information listed in (a) through (e) above at least 90 days prior to commencement of discharge.

Within 30 days following the final date of compliance with a pretreatment standard the industrial user subject to pretreatment standards and requirements shall submit a report to the County indicating the nature and concentration of all pollutants regulated by the pretreatment standard the average and maximum daily flow for the industrial process units. The report shall also state whether pretreatment standards or requirements are being met and if not, the operation and maintenance and/or pretreatment will be necessary to bring the discharge into compliance.

3. After the final compliance report for a pretreatment standard, the subject industrial user shall periodically submit a report to the County indicating the nature and concentration of pollutants in the effluent which are limited by the pretreatment standard. These reports shall be submitted in June and December of each year unless required more frequently by the Airports Administrator.
