Sec. 24-42(1). General Conditions of the Industrial Wastewater Discharge Permit.
(a) No person shall discharge or cause to be discharged industrial wastewater into the public sewer without first obtaining a permit for industrial wastewater discharge for each connection. However, certain persons as defined in minor section 24-42(2) are exempt from obtaining a discharge permit. Exemption from obtaining a permit shall not be construed as exempting a person from any other provisions in this article. In situations where an establishment or class of establishments exempt from obtaining a permit is shown to discharge prohibited substances or to exceed the concentration limitations of restricted substances, that establishment or class of establishments may be required to install pretreatment facilities or take other action to prevent the prohibited discharges.
(b) The permit may require pretreatment of industrial wastewater prior to discharge, restriction of peak discharges, relocation of a point discharge, disposal of certain restricted wastes by alternative methods, reuse of process wastewater where economically feasible, installation of metering and sampling manholes, the reporting of discharge volumes and wastewater sampling data, and the repayment of excessive treatment costs not covered by the user charge.
(c) No permit is transferable without written consent of the director.
(d) No person shall discharge industrial wastewater in excess of the quantity or quality limitations set by the permit.
(e) Any person desiring to discharge wastewater or use facilities which are not in conformance with the permit should apply to the director for an amended permit. Major industrial users shall apply for an amended permit not less often than annually. Such amended permit shall be based on the monitoring required by minor section 24-43(5).
Sec. 24-42(2). Identification of Persons Required To Obtain A Permit.
(a) Any user discharging to the public sewer system, not specifically exempt in paragraph (b), identified in the Standard Industrial Classification (SIC) Manual, 1972, Office of Management and Budget, as amended and supplemented, under the following divisions shall apply for a permit from the department of water and sewers within three (3) months after the passage of this article or prior to making a new connection:
1. Division A--Agriculture, forestry, and fishing;
2. Division B--Mining;
3. Division D--Manufacturing;
4. Division E--Transportation, communications, electric, gas and sanitary services;
5. Division I--Services.
(b) A user in the divisions listed may be exempt from obtaining a permit if it is determined that the discharges will be from primarily sanitary conveniences. The director shall establish guidelines for deciding whether a permit is required in those cases where the term "primarily" is doubtful.
(c) Where more than one (1) SIC classification is applicable to an establishment, the classification that requires the most stringent requirement shall be used.
Sec. 24-42(3). Procedure for Obtaining an Industrial Wastewater Discharge Permit. Applicants for a permit shall complete an application form available from the department of water and sewers. The completed form, along with any required plans and data, shall be processed by the department. The application shall be approved if the applicant has complied with all applicable requirements of this article and furnished to the director all requested information, and if the director determines that there is adequate capacity in the agency's facilities, based upon sound engineering criteria, to convey, treat and dispose of the wastewater. Upon approval, the director or his designated representative, will sign the application form. When properly signed, the application form shall constitute a valid industrial wastewater discharge permit.
Sec. 24-42(4). Change of permit restrictions. The director may change the restrictions or conditions of a permit when necessary to comply with Environmental Protection Agency regulations on wastewater discharges to municipal treatment systems, to reduce the levels of incompatible wastes in the treated wastewater effluent thereby allowing beneficial reuse of the effluent wastewater to comply with the requirements of the NPDES permit to discharge, or as circumstances may require.
