14.60.508 Industrial wastewater discharge permit – Reporting required

14.60.508 Industrial wastewater discharge permit – Reporting required.

All dischargers subject to national categorical pretreatment regulations must submit a 90-day compliance report within 90 days after the date the final national categorical pretreatment compliance must be achieved or, in the case of a new discharger, 90 days after the discharger starts to discharge to the POTW. The information provided in this report shall contain the same information as required by the baseline monitoring report as found in 40 CFR 403.12(b).

A. Identifying Information. The user shall submit the name and address of the facility including the names of the operator and owners.

B. Permits. The user shall submit a list of any environmental control permits held by or for the facility.

C. Description of Operations. The user shall submit a brief description of the nature, average rate of production, and standard industrial classification of the operation(s) carried out by such industrial user, including a list of all raw materials and chemicals used or stored at the facility which are, or could accidentally or intentionally be, discharged to the POTW; number and type of employees; hours of operation; each product produced by type, amount, process or processes, and rate of production; type and amount of raw materials processed (average and maximum per day) and the time and duration of discharges. This description should also include a schematic process diagram which indicates points of discharge to the POTW from the regulated or manufacturing processes. Site plans, floor plans, mechanical and plumbing plans showing details of all sewers, sewer connections, inspection manholes, sampling chambers and appurtenances by size, location and elevation are required.

1. Categorical User. The user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:

a. Regulated or manufacturing process streams; and

b. Other streams as necessary to allow use of the combined waste stream formula of 40 CFR 403.6(e).

2. Noncategorical User. The user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:

a. Total process flow, wastewater treatment plant flow, total plant flow or individual manufacturing process flow as required by the director.

The city may allow for verifiable estimates of these flows where justified by cost or feasibility considerations.

a. The user shall identify the applicable pretreatment standards for each regulated or manufacturing process.

b. In addition, the user shall submit the results of sampling and analysis identifying the nature and concentration (or mass) where required by the categorical pretreatment standard or as required by the city of regulated pollutants (including standards contained in LMC 14.60.300 through 14.60.3015, specific prohibitions) as appropriate in the discharge from each regulated or manufacturing process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations and shall conform to sampling and analytical procedures outlined in LMC 14.60.530.

c. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this subsection.

d. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e) for a categorical user covered by a categorical pretreatment standard, this adjusted limit along with supporting data shall be submitted as part of the application.

a. The user shall identify the applicable pretreatment standards for its wastewater discharge.

b. In addition, the user shall submit the results of sampling and analysis identifying the nature and concentration (or mass where required by the city) of regulated pollutants contained in LMC 14.60.300 through 14.60.3015, specific prohibitions) as appropriate in the discharge. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations and shall conform to sampling and analytical procedures outlined in LMC 14.60.530.

c. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this subsection.

d. Where the director develops alternate concentration or mass limits because of dilution, the adjusted limit along with supporting data shall be submitted as part of the application.

F. Certification. A statement, reviewed by an authorized representative of the user and certified by a qualified professional as outlined in LMC 14.60.509, indicating whether the applicable 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 for the user to meet the applicable pretreatment standards and requirements.

G. Compliance Schedule. If additional pretreatment and/or O&M will be required to meet the applicable pretreatment standards, the city will establish the shortest schedule by which the user will provide such additional pretreatment and/or O&M. The schedule shall conform to the requirements of LMC 14.60.380, Compliance with applicable pretreatment requirements.

1. Where the user’s categorical pretreatment standard has been modified by a removal allowance (40 CFR 403.7), the combined waste stream formula (40 CFR 403.6(e)), and/or a fundamentally different factors variance (40 CFR 403.13) at the time the user submits the report required by this subsection, the information required by subsections (D) and (E) of this section shall pertain to the modified limits.

2. If the categorical pretreatment standard is modified by a removal allowance (40 CFR 403.7), the combined waste stream formula (40 CFR 403.6(e)), and/or a fundamentally different factors variance (40 CFR 403.13) after the user submits the report required by subsections (D) and (E) of this section, then a new report shall be submitted by the user within 60 days after the modified limit is approved.

H. Any other information as may be deemed necessary by the director to evaluate the wastewater discharge permit application. Incomplete or inaccurate applications will not be processed and will be returned to the user for revision.

For users subject to equivalent mass or concentration limits established by the city in accordance with procedures established in 40 CFR 403.6(c), 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 permit holders are required to submit wastewater discharge monitoring reports to the pretreatment office at the frequencies and times designated in the discharge permit, but in no event less frequent than semi-annually. The report forms shall be furnished by the city. Submitted forms must contain all the results of analyses of the wastewater discharge performed by the permittee, even if the analyses are not required by the permit, and any other information required by the permit or requested on the form itself. The reports must be complete, accurate, and signed by an authorized representative of the discharger.

If any violation has occurred during the reporting period, the discharger must repeat the sampling and analyses and submit the results to the city. The resampling data must be submitted to the city within 30 days after the discharger becomes aware a violation has occurred. Resampling analyses shall not be used for satisfying regular compliance monitoring requirements. (Ord. 3220 § 2, 2016; Ord. 2742 § 2, 2008; Ord. 1705, 1989)
