§ 3-5-285. Periodic reporting.

The user will be required to submit to the general manager reports indicating the nature and concentration of effluents on a periodic basis. Specific reporting requirements will be indicated in the user's permit.

(1)

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 procedures approved by EPA.

(2)

Sample collection:

a.

Except as indicated in subsection b, below, the user must collect wastewater samples using flow proportional composite collection techniques. In the event flow proportional sampling is not feasible, the general manager may authorize the use of time proportional sampling or a minimum of four (4) grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.

b.

Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.

(3)

Timing: Written reports will be deemed to have been submitted on the date postmarked. For reports that 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.

(4)

Record keeping: Users subject to the reporting requirements of this ordinance shall retain, and make available for inspection and copying, all records of information obtained pursuant to monitoring activities required by this article and any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements. 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 (3) years. This period shall be automatically extended for the duration of any litigation concerning the user or the authority, or when the user has been specifically notified of a longer retention period by the general manager.
