The nonresidential user shall apply for permit re-issuance a minimum of 90 days prior to the expiration of this existing permit if it desires to continue the uninterrupted discharge of restricted substances.
(E) Conditions. Wastewater discharge permits shall be expressly subject to all provisions of this subchapter. Permits may contain the following conditions:
(1) Payment of applicable fees and charges;
(2) Limits on the average and maximum discharge of restricted substances;
(3) Limits on the average and maximum rate and time of discharge or requirements for flow regulation and equalization;
(4) Requirements for installation and maintenance of pretreatment, inspection or monitoring and sampling facilities;
(5) Specifications for monitoring and sampling programs which may include monitoring and sampling locations, frequency of monitoring and sampling, number, types and standards for tests and reporting schedules;
