(A) Wastewater discharge permits and wastewater contribution permits shall be expressly subject to all provisions of this subchapter and all other applicable regulations, user charges and fees established by the district. The district may authorize an 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 without any increase in the pollutant due to activities of the industrial user.
(B) This authorization is subject to the conditions established in 40 C.F.R. § 403.12(e) (2). Permits may contain the following:
(1) The unit charge or schedule of user charges and fees for the wastewater to be discharged to a community sewer;
(2) Effluent limits, including best management practices and slug controls, on the average and maximum rate and time of discharge or requirements for flow regulations and equalization, wastewater constituents and characteristics;
(3) Requirements for installation and maintenance of inspection and sampling facilities;
(4) Specifications for monitoring programs,- which may include sampling locations, frequency of sampling, number, types and standards for tests and reporting scheduling;
(5) Compliance schedules;
(7) Requirements for maintaining and retaining plant records relating to wastewater discharge as specified by the district, and affording district access thereto as required by 40 C.F.R. § 403.12(o)(2);
(8) Requirements for notification to the district of any new introduction of wastewater constituents or any substantial change in the volume or character of the wastewater constituents being introduced into the wastewater treatment systems;
(9) Requirements for notification of slug discharges as per § 52.35(D)(7)(d) of this chapter;
(10) Other conditions as deemed appropriate by the district to ensure compliance with this subchapter;
(11) Where an effluent from an industrial process is mixed prior to treatment with wastewaters other than those generated by the regulated process, fixed alternative discharge limits may be derived for the discharge permit by the district. These alternative limits shall be applied to the mixed effluent. These alternative limits shall be calculated using the combined wastestream formula and/or flow-weighted average formula given in 40 C.F.R. § 403.6(e). Where the effluent limits in a categorical pretreatment standard are expressed only in terms of mass of pollutants per unit of production (production-based standard), the district may convert the limits to equivalent limitations expressed either as mass of pollutant that may be discharged per day or of effluent concentration for purposes of calculating effluent permit limitations applicable to the permittee. The permittee shall be subject to all permit limits calculated in this manner under 40 C.F.R. § 403.6(c) and must fully comply with these alternative limits. All categorical industrial users subject to production-based standards must report production rates annually so that alternative permit limits can be calculated if necessary. The categorical industrial user must notify the district 30 days in advance of any change in production levels that might affect the flow or other data used to calculate the effluent limits in the discharge permit;
(12) The permit may require the user to reimburse the district for all expenses related to monitoring, sampling and testing performed at the direction of the district and deemed necessary by the district to verify that the user is in compliance with the permit;
(13) A statement that indicates the industrial user permit issuance date, expiration date and effective date;
(14) A statement that the industrial user permit is nontransferable;
(15) Requirements to control slug discharge, if determined by the district to be necessary;
(16) The process for seeking a waiver from monitoring for a pollutant neither present nor expected to be present in the discharge in accordance with this chapter. Any grant of a waiver by the district must be included as a condition in the user’s permit; and
(17) A statement of applicable civil and criminal penalties for violation of pretreatment standards and requirements, and any applicable compliance schedule. Such schedule may not extend the time for compliance beyond that required by applicable federal, state or local law.
