PRETREATMENT OF WASTEWATER
Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all pretreatment standards, local limits, and the prohibitions set out in this chapter within the time limitations specified by EPA, the state, or the Control Authority, whichever is more stringent. Any facilities necessary for compliance should be provided, operated, and maintained at the user's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the Control Authority for review, and shall be acceptable by the Control Authority before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the Control Authority under the provisions of this chapter.
(Ord. 2005-8-226, passed 8-2-05)
(A) Whenever deemed necessary, the Control Authority may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specialty sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter.
(B) The Control Authority may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
(C) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Control Authority, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand except that such interceptors shall not be required for residential users. All interception units shall be of type and capacity approved by the Control Authority and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at the user's expense.
(D) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(Ord. 2005-8-226, passed 8-2-05)
At least once every two years the Control Authority shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Control Authority may require any user to develop, submit for approval, and implement such a plan. An accidental discharge/slug control plan shall address, at a minimum, the following:
(A) Description of discharge practices, including nonroutine batch discharges;
(B) Description of stored chemicals;
(C) Procedures for immediately notifying the Control Authority of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharges in this chapter; and
(D) Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.
(E) In the case of any discharge, including but not limited to, accidental discharges, discharges of a nonroutine, episodic nature, a non-customary batch discharge, or a slug load that may cause potential problems for the system, it is the responsibility of the user to immediately telephone and notify the Control Authority of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user.
(F) Within five days following an accidental discharge, the user shall submit to the Control Authority a detailed written report, describing the nature and cause of the discharge and the measures to be taken by the user to prevent similar future occurrences.
(1) Such notification shall not relieve the user of any expense, loss, damage or other liability that may be incurred as a result of damage to the system, the environment, or any other damage to user or property.
(2) Nor shall such notification relieve the user of any fines, penalties or other liability that may be imposed by this chapter or other applicable law.
(G) Failure to notify the Control Authority of an accidental discharge may result in legal action or discontinuation of service.
(H) Notice to employees.
(1) As a part of the accidental spill prevention plan, a notice shall be permanently posted on the user's bulletin board or other prominent place, advising employees whom to call in the event of an accidental discharge.
(2) Employers shall insure that all appropriate employees are advised of the emergency notification procedures to be used in the event of an accidental discharge.

WASTEWATER DISCHARGE PERMIT APPLICATION
When requested by the Control Authority, a user must submit all information required by the Control Authority, including, but not limited to, information on the nature and characteristics of the users wastewater. The Control Authority is authorized to prepare a form for this purpose and may periodically require users to submit or update the information.
(Ord. 2005-8-226, passed 8-2-05)
(A) No significant industrial user shall discharge wastewater into the POTW without first obtaining a wastewater discharge permit from the Control Authority, except a significant industrial user that has filed a timely application pursuant to this chapter may continue to discharge for the time period specified therein.
(B) The Control Authority may require other users to obtain wastewater discharge permits as necessary to carry out the purposes of this chapter.
(C) Any violation of the terms and conditions of a wastewater discharge permit shall be deemed a violation of this chapter and subjects the wastewater discharge permittee to the sanctions set out in this chapter. Obtaining a wastewater discharge permit does not relieve a permittee of its obligation to comply with all federal and state pretreatment standards or requirements or with any other requirements of federal, state, or local law.
