A. Any user that is required to have an industrial waste discharge permit and performs self-monitoring shall submit to the City during the months of June and December, unless the City has determined that the self-monitoring may be reduced to report no less frequently than once a year, or unless required more frequently in the pretreatment standard or by the DEQ, a report indicating the nature of the effluent over the previous reporting period. The frequency of monitoring shall be as prescribed within the industrial waste discharge permit. A reporting form will be provided by the City. At a minimum, users shall sample their discharge at least twice per year, unless required less frequently as described above. In cases where a local limit requires compliance with a best management practice or pollution prevention alternative, the user must submit documentation required by City to determine the compliance status of the user.

B. Periodic compliance reports are to be postmarked or received by the Industrial Pretreatment Department by on or before the fifteenth of the month following the conclusion of the reporting period.

C. The report shall include a record of the concentrations (and mass if specified in the wastewater discharge permit) of the pollutants listed in the wastewater discharge permit that were measured and a record of all flow measurements (average and maximum) taken at the designated sampling locations and shall also include any additional information required by this title or the wastewater discharge permit. Production data shall be reported if required by the wastewater discharge permit. Both daily maximum and average concentration (or mass, where required) shall be reported. If a user sampled and analyzed more frequently than what was required by the City or by this title, using methodologies in 40 CFR Part 136, it must submit all results of sampling and analysis of the discharge during the reporting period. All laboratory reports providing data for organic and metal parameters shall include the following information: sampling date, sample location, date of analysis, parameter name, CAS number, analytical method/number, method detection limit (MDL), laboratory practical quantitation limit (PQL), reporting units, and concentration detected. Analytical results from samples sent to a contracted laboratory must have information on the chain of custody, the analytical method, QA/QC results, and documentation of accreditation for the parameter.

D. The City may authorize the industrial user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard if the industrial user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is present only at background levels from intake water and without any increase in the pollutant due to activities of the industrial user.

E. Any user subject to equivalent mass or concentration limits established by the City or by unit production limits specified in the applicable categorical standards shall report production data.

F. If the City calculated limits to factor out dilution flows or nonregulated flows, the user will be responsible for providing flows from the regulated process flows, dilution flows and nonregulated flows.

G. Flows shall be reported on the basis of actual measurement; provided, however, that the City may accept reports of average and maximum flows estimated by verifiable techniques if the City determines that an actual measurement is not feasible.

H. Discharges sampled shall be representative of the user’s daily operations and samples shall be taken in accordance with this title. In cases where the pretreatment standard requires compliance with a best management practice (or pollution prevention alternative), the user shall submit documentation required by the City or the pretreatment standard necessary to determine the compliance status of the user.

I. The City may require reporting by users that are not required to have an industrial wastewater discharge permit if information or data is needed to establish a sewer charge, determine the treatability of the effluent, or determine any other factor which is related to the operation and maintenance of the sewage system.

J. The City may require self-monitoring by the user or, if requested by the user, may agree to perform the periodic compliance monitoring needed to prepare the periodic compliance report required under this section. If the City agrees to perform such periodic compliance monitoring, it may charge the user for such monitoring, based upon the costs incurred by the City for the sampling and analyses. The user may be charged for the cost of resampling by the City in the event of a violation or violations. Any such charges shall be added to the normal sewer charge and shall be payable as part of the sewer bills. The City is under no obligation to perform periodic compliance monitoring for a user.

K. Users that have approved monitoring waivers as to specific pollutants must certify on each report that there has been no increase in the specific pollutant in the wastestream due to activities of the user. The certification shall be in the following form:

Based on my inquiry of the person or persons directly responsible for managing compliance with the Pretreatment Standard for 40 CFR ____ [specify applicable National Pretreatment Parts], I certify that, to the best of my knowledge and belief, there has been no increase in the level of _____ [list pollutant(s)] in the wastewaters due to the activities at the facility since the filing of the most recent report.
