A. Final Compliance Report: Within ninety (90) days following the date for final compliance by the user with applicable pretreatment standards and requirements set forth in this chapter or an indirect discharge permit, or within ninety (90) days after commencement of the introduction of wastewater into the POTW by a new user, including new source users, any user when required shall submit to the city a report indicating the nature and concentration of all prohibited or regulated substances contained in its discharge, and the average and maximum daily flow in gallons. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional operation, maintenance, and/or pretreatment is necessary to bring the user into compliance with the applicable pretreatment standards or requirements. This statement shall be signed by an "authorized representative of the user" as defined in section 7-4-3 of this chapter. For categorical users, this report shall contain the information outlined in subsections 7-4-14B1c, B1d, B1f, and B1k of this chapter.
B. Periodic Compliance Reports:
1. Any user subject to a pretreatment standard set forth in this chapter, after the compliance date of such pretreatment standard, or, in the case of a new user, after commencement of the discharge to the POTW, shall submit to the city at six (6) month intervals as prescribed in the indirect discharge permit, unless required more frequently by the city, a report indicating the nature and concentration of prohibited or regulated substances in the effluent which are limited by the pretreatment standards hereof. In addition, this report shall include a record of all measured or estimated average and maximum daily flows during the reporting period. Flows shall be reported on the basis of actual measurement, provided, however, where cost or feasibility considerations justify, the city may accept reports of average and maximum flows estimated by verifiable techniques. This report shall also include any additional information as may be required by this chapter or the indirect discharge permit, including production data and flow measurements from any dilute or nonregulated waste streams.
2. Reports of users shall contain all results of sampling and analyses of the discharge, including the flow and the nature and concentration, or production and mass where required by the city. All sample results shall indicate the time, date and place of sampling, and methods of analyses, and shall certify that the discharge sampled is representative of discharges of normal work cycles and expected pollutant discharges from the user. The frequency of monitoring by the user shall be prescribed within the indirect discharge permit. If a user sampled and analyzed more frequently than what was required in its indirect discharge permit, it must submit all results of sampling and analyses of the discharge as part of its self-monitoring report.
3. All users not required to obtain an indirect discharge permit shall provide appropriate reports to the city as may be required.
C. Noncompliance Notification, Resampling, And Reporting: If sampling performed by a user indicates a violation, the user shall notify the city within twenty four (24) hours of becoming aware of the violation. The user shall also repeat the sampling within five (5) days and submit the results of the repeat analysis to the city within thirty (30) days after becoming aware of the violation, except the user is not required to resample if:
1. The city performs sampling at the user at a frequency of at least once per month, or
2. The city performs sampling at the user between the time when the user performs its initial sampling and the time when the user receives the results of this sampling.
D. Notification Of Significant Production Changes: Any users operating under an indirect discharge permit incorporating equivalent mass or concentration limits shall notify the city within two (2) business days after the user has a reasonable basis to know that the production level will significantly change within the next calendar month. Any user not providing a notice of such anticipated change will be required to comply with the existing limits contained in its indirect discharge permit.
E. Hazardous Waste Notification:
1. Any user that is discharging more than fifteen (15) kilograms of hazardous wastes as defined in 40 CFR 261 (listed or characteristic wastes) in a calendar month or any facility discharging any amount of acutely hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e) is required to provide a onetime notification in writing to the city, EPA regional waste management division director, and Idaho division of environmental quality. Any existing user exempt from this notification, shall comply with the requirements contained herein within thirty (30) days of becoming aware of a discharge of fifteen (15) kilograms of hazardous wastes in a calendar month or the discharge of acutely hazardous wastes to the city sewer system. Such notification shall include:
a. The name of the hazardous waste as set forth in 40 CFR part 261,
b. The EPA hazardous waste number, and
c. The type of discharge (continuous, batch, or other).
d. If an industrial user discharges more than one hundred (100) kilograms of such waste per calendar month to the sewer system, the notification shall also contain the following information to the extent it is known or readily available to the industrial user:
(1) An identification of the hazardous constituents contained in the wastes,
(2) An estimation of the mass and concentration of such constituents in the waste streams discharged during that calendar month, and
(3) An estimation of the mass of constituents in the waste streams expected to be discharged during the following twelve (12) months.
2. These notification requirements do not apply to pollutants already reported under the self-monitoring requirements. Whenever the EPA publishes final rules identifying additional hazardous wastes or new characteristics of hazardous waste, a user shall notify the city of the discharge of such a substance within ninety (90) days of the effective date of such regulations. In the case of any notification made pursuant to this section, an industrial user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.
F. Notice Of Potential Problems, Including Accidental Spills And Slug Loads: Any user shall notify the city immediately of all discharges that may cause problems to the POTW, including any slug loads, as defined in section 7-4-3 of this chapter. The notification shall include the concentration and volume and corrective action. Steps being taken to reduce any adverse impact to the POTW should also be noted during the notification. Any user that discharges pollutants shall be liable for any expense, loss, or damage to the POTW, in addition to the amount of any fines imposed on the city under state or federal law.
G. Notification Of Changed Discharge: All users shall promptly notify the city in advance of any substantial change in the volume or character of pollutants in their discharge, including significant manufacturing process changes, pretreatment modifications, and the listed or characteristic hazardous wastes for which the user has submitted initial notification under subsection E of this section.
