13.90.380 Periodic compliance reports.
(1) The Public Works Director may specify the necessary minimum sampling and reporting frequencies and include applicable requirements in permits. Industrial users must:
(a) Report at least twice a year, in January and July, unless otherwise specified in a permit;
(b) Report the flows and concentrations of regulated pollutants in all discharges subject to pretreatment standards;
(c) Report average and maximum daily flows for the reporting period and identify where flow estimates are used; and
(d) Include the documentation needed to show compliance with applicable BMPs, pollution prevention alternatives, maintenance, treatment, or recordkeeping requirements.
(2) The Public Works Director may authorize a CIU to forego sampling of a pollutant regulated by a categorical standard when it is not present in raw wastewater, provided:
(a) The CIU submits a request for the waiver with their permit application or reapplication (see PMC 13.90.230(1)(h)).
(b) The CIU analyzes a sample (or samples) representative of all wastewater from all processes before any treatment and includes all results with the request.
(c) The CIU demonstrates through source water and untreated process water sample results that the pollutant never exceeds intake water levels. (Pollutants simply reduced by treatment to background levels are ineligible for the waiver.)
(d) The CIU shows, where nondetectable sample results are returned in subsections (2)(b) or (2)(c) of this section, that they used the method from 40 CFR Part 136 with the lowest detection level.
(e) The duly authorized representative of the CIU signs the request using the certification statement of PMC 13.90.480(1).
(f) The CIU includes, in routine monitoring reports, the statement in PMC 13.90.480(2), certifying that there has been no increase in the pollutant in its wastestream due to activities of the industrial user.
(g) The CIU reports and immediately resumes the monitoring which would otherwise have been required upon discovering that a waived pollutant is present or expected to be present based on changes to the user’s operations or system.
The Public Works Director will document the reasons supporting the waiver in the permit fact sheet, and keep any information submitted by the user and the fact sheet for three years after the waiver expires. Monitoring waivers are valid after being incorporated in a user’s permit. The waiver is in effect while the permit is effective, up to five years. The Public Works Director may cancel a monitoring waiver at any time for any reason.
(3) Users must sign and certify all periodic compliance reports in accordance with PMC 13.90.480.
(4) Users must take wastewater samples which are representative of their range of discharge conditions and of any discharge not disclosed in their permit application. Users must properly operate, clean, and maintain sampling and flow metering facilities and devices and provide they function properly. The Public Works Director may not allow user claims that sampling results are unrepresentative due to a user’s failure to meet this requirement.
(5) Users subject to the reporting requirements in this section must report any additional monitoring which might determine compliance with permit requirements. This includes any additional monitoring of regulated pollutants at their respective effluent monitoring locations using procedures prescribed in PMC 13.90.440. In such cases, the results of this monitoring shall be included in periodic monitoring reports.
(6) Users that send electronic (digital) documents to the City to satisfy the requirements of this section must meet all state and federal electronic signature requirements. Electronic data shall be in the format required by the Public Works Director. The Public Works Director may also require reporting in both digital and traditional format.
(7) The City reserves the right to require users to submit reports electronically at such time as the City implements the ability to handle electronic reporting as per state and federal rules pertaining to electronic reporting. [Ord. 4169 § 1, 2014; Code 1970 § 13.62.060(D).]
