1045.10 PRETREATMENT OF WASTEWATER.
(a) Pretreatment Facilities. Industrial users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in Section 1045.09(a) within the time limitations specified by the EPA, the State or the Enforcing Officer, whichever is more stringent. Any facilities required to pretreat wastewater to a level acceptable to the POTW shall be provided, operated, and maintained at the industrial user’s expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the POTW for review, and shall be acceptable to the POTW before construction of the facility. The review of such plans and operating procedures will in no way relieve the industrial user from the responsibility of modifying the facility as necessary to produce an acceptable discharge to the POTW under the provisions of this chapter.
(b) Additional Pretreatment Measures.
(1) Whenever deemed necessary, the Enforcing Officer may require industrial users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and impose such other conditions as may be necessary to protect the POTW and determine the industrial user’s compliance with the requirements of this chapter.
(2) Each person discharging into the POTW greater than 25,000 gallons of wastewater per day or greater than fifty percent of the average daily flow in the POTW, whichever is less, shall install and maintain, on his or her property and at his or her expense, a suitable storage and flow control facility to insure equalization of flow over a twenty-four hour period. The facility shall have a capacity for at least fifty percent of the daily discharge volume and shall be equipped with alarms and a rate of discharge controller, the regulation of which shall be directed by the Enforcing Officer. A wastewater discharge permit may be issued solely for flow equalization. As an alternative, the industrial user may, with the consent of the Enforcing Officer, develop and implement a discharge/slug control plan.
(3) Grease, oil and sand interceptors shall be provided when, in the opinion of the Enforcing Officer, 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 a type and capacity approved by the Enforcing Officer and shall be so located as to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner, at his or her expense.
(4) Industrial users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(5) At no time shall two readings on an explosion hazard meter at the point of discharge into the POTW be more than ten percent, nor shall any single reading be over five percent of the lower explosive limit (LEL) of the meter.
(c) Accidental Discharge/Slug Control Plans. The Enforcing Officer may require any industrial user to develop and implement an accidental discharge slug control plan. At least once every two years, the Enforcing Officer shall evaluate whether each significant industrial user needs such a plan. Any industrial user required to develop and implement an accidental discharge/control slug plan shall submit a plan which addresses, at a minimum, the following:
(1) A description of discharge practices, including nonroutine batch discharges.
(2) A description of stored chemicals.
(3) Procedures for immediately notifying the POTW of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharges provided in Section 1045.09(a).
(4) 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 run-off, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.
In the event of an accidental discharge, the industrial user shall be required to comply with the reporting requirements of Section 1045.13(0.
(d) Tenant Responsibility. Where an owner of property leases premises to any other person as a tenant under any rental or lease agreement, if either the owner or the tenant is an industrial user, either or both may be held responsible for compliance with the provisions of this chapter. Both generators and transporters of hauled waste may be held jointly and severally responsible for compliance with the provisions of this chapter.
(e) Hauled Wastewater.
(1) Hauled wastewater may be accepted into the POTW at a designated receiving structure within the treatment plant area, and at such times as are established by the Enforcing Officer, provided such wastes do not violate Section 1045.09 or any other requirements established or adopted by this POTW. A general wastewater discharge permit for individual transporters to use such facilities shall be issued by the Enforcing Officer. A letter of intent shall also be issued by the Enforcing Officer to the transporter, specifically as an addendum to the general permit.
(2) The discharge of hauled non-residential waste requires prior approval from the Enforcing Officer. The Enforcing Officer shall have authority to prohibit the disposal of such wastes, if such disposal would interfere with the treatment plant operation. Wastehaulers are subject to all other sections of this chapter.
(3) Fees for discharging hauled wastewater will be established in the Wastehauler’s Agreement, with an addendum by the letter of intent. Other fees may apply as established in Section 1045.30.
(f) Vandalism. No person shall maliciously, willfully or negligently break, damage, destroy, uncover, deface, tamper with or prevent access to any structure, appurtenance or equipment, or other part of the POTW. Any person found in violation of this requirement shall be subject to the sanctions set out in Sections 1045.17 to 1045.28, 1045.31, 1045.82, and the penalties provided in Section 1045.99. (Ord. 775. Passed 7-15-98.)
1045.11 WASTEWATER DISCHARGE PERMIT ELIGIBILITY.
(a) Wastewater Survey. When requested by the Enforcing Officer, all industrial users must submit information on the nature and characteristics of their wastewater by completing a wastewater survey prior to commencing their discharge. The Enforcing Officer is authorized to prepare a form for this purpose and may periodically require industrial users to update the survey. Failure to complete this survey shall be reasonable grounds for terminating service to the industrial user and shall be considered a violation of this chapter.
(b) Wastewater Discharge Permit Requirement.
(1) It shall be unlawful for any significant industrial user to discharge wastewater into the POTW without first obtaining a wastewater discharge permit from the Enforcing Officer. Any violation of the terms and conditions of a wastewater discharge permit shall be deemed a violation of this chapter and subject the wastewater discharge permittee to the sanctions set forth in Sections 1045.17 to 1045.28, 1045.31, 1045.32, and the penalties provided in Section 1045.99. 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 and local law.
(2) The Enforcing Officer shall require other industrial users, including waste haulers, to obtain wastewater discharge permits as necessary to carry out the purposes of this chapter.
(c) Existing Connections. Any significant industrial user who discharges industrial waste into the POTW prior to the effective date of this chapter, and who wishes to continue such discharges in the future, shall, within thirty days after said date, apply to the POTW for a wastewater discharge permit in accordance with subsection (f) hereof, and shall not cause or allow discharges to the POTW to continue after sixty days of the effective date of this chapter, except in accordance with a wastewater discharge permit issued by the Enforcing Officer.
(d) New Connections. Any significant industrial user proposing to begin or recommence discharging industrial wastes into the POTW must obtain a wastewater discharge permit prior to the beginning or recommencing of such discharge. An application for the wastewater discharge permit must be filed at least ninety days prior to the date upon which any discharge will begin.
(e) Extrajurisdictional Industrial Use.
(1) Any existing significant industrial user located beyond the POTW’s limits shall submit a wastewater discharge permit application, in accordance with subsection (0 hereof, within thirty days of the effective date of this chapter. New significant industrial users located beyond the POTW’s limits shall submit such applications to the Enforcing Officer thirty days prior to any proposed discharge into the POTW.
(2) Alternatively, the Enforcing Officer may enter into an agreement with the neighboring jurisdiction in which the significant industrial user is located to provide for the implementation and enforcement of pretreatment program requirements against said industrial user.
(f) Permit Application Contents. In order to be considered for a wastewater discharge permit, all industrial users required to have a wastewater discharge permit must submit the information required by Section 1045.13(a)(2). The Enforcing Officer shall approve a form to be used as a permit application. In addition, the following information may be requested:
(1) A description of activities, facilities, and plant processes on the premises, including a list of all raw materials and chemicals used or stored at the facility which are, or could accidentally or intentionally be, discharged to the POTW.
(2) The number and type of employees, hours of operation, and proposed or actual hours of operation of the POTW.
(3) Each product produced by type, amount, process or processes, and rate of production.
(4) The type and amount of raw materials processed (average and maximum per day).
(5) The site plans, floor plans, mechanical and plumbing plans, and details to show all sewers, floor drains, and appurtenances by size, location, and elevation, and all points of discharge.
(6) The time and duration of the discharge.
(7) Any other information as may be deemed necessary by the Enforcing Officer to evaluate the wastewater discharge permit application.
Incomplete or inaccurate applications will not be processed and will be returned to the industrial user for revision.
(g) Application Signatories and Certification. All wastewater discharge permit applications and industrial user reports must contain the following certification statement and be signed by an authorized representative of the industrial user.
“I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.”
(h) Permit Application Evaluation. The Enforcing Officer will evaluate the data furnished by the industrial user and may require additional information. Within thirty days of receipt of a complete wastewater discharge permit application, the Enforcing Officer will determine whether or not to issue a wastewater discharge permit. The Enforcing Officer may deny any application for a wastewater discharge permit.
(i) Decertification. The Enforcing Officer may decertify an industrial user out of the POTW wastewater discharge permit requirements upon application by the industrial user, completion of a certification statement and fulfillment of all requirements and conditions mandated by the Enforcing Officer. The decision as to whether an industrial user meets the requirements for desertification shall be determined at the discretion of the Enforcement Officer.
