§ 51.163 ACCIDENTAL DISCHARGE/SLUG CONTROL PLANS.

   At least once every two years, the Wastewater Utility Manager shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Wastewater Utility Manager 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 non-routine batch discharges;

   (B)   Description of stored chemicals;

   (C)   Procedures for immediately notifying the Wastewater Utility Manager of any accidental or slug discharge, as required by § 51.227; and

   (D)   Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures must 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 measures and equipment for emergency response. Acceptance or approval of any discharge/slug control plan by the Wastewater Utility Manager does not in any way provide protection for any industrial user from enforcement, legal actions, or other actions as allowed by this subchapter.

§ 51.164 HAULED WASTEWATER.

   (A)   Wastewater haulers shall have a valid wastewater hauler permit issued by the state before discharging wastes to the POTW. Wastewater haulers that discharge to the city shall provide access to all documentation required to be kept by the wastewater hauler permit issued by the state.

   (B)   Wastewater may be introduced into the POTW only at locations designated by the Wastewater Utility Manager, and at such times as are established by the Wastewater Utility Manager. Such waste shall not violate §§ 51.110 through 51.122 or any other requirements established by the city.

   (C)   All procedures for discharging, for cleanliners, and for general sanitary operation on city property as prescribed by the city shall be strictly adhered to by all wastewater haulers delivering wastewater to the designated city dumping station.

   (D)   Wastewater from a domestic level user shall not be mixed with wastewater from an industrial user. Vehicles hauling wastewater from an industrial user shall not be used to haul wastewater from a domestic level user for disposal at the POTW.

   (E)   Hauled wastewater shall be from domestic sources only and shall not, partly or completely, contain industrial waste of any kind.

   (F)   The Wastewater Utility Manager has the right to refuse any waste from any wastewater hauler for any reason.

§ 51.165 BYPASS.

   Upon delegation of a local pretreatment program from IDEM and the U.S. EPA to the city, bypass shall follow the IDEM permit conditions as well as the following:

   (A)   For the purposes of this section:

      (1)   BYPASS means the intentional diversion of wastestreams from any portion of a user’s treatment facility; and

      (2)   SEVERE PROPERTY DAMAGE means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. SEVERE PROPERTY DAMAGE does not mean economic loss caused by delays in production.

   (B)   A user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provision of divisions (C) and (D) below.

   (C)   (1)   If a user knows in advance of the need for a bypass, it shall submit prior notice to the Wastewater Utility Manager, at least ten days before the date of the bypass.

      (2)   A user shall submit oral notice to the Wastewater Utility Manager of an unanticipated bypass that exceeds applicable pretreatment standards within 24 hours from the time it becomes aware of the bypass. A written submission shall also be provided within five days of the time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause; the duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The Wastewater Utility Manager may waive the written report on a case-by-case basis if the oral report has been received within 24 hours.

   (D)   (1)   Bypass is prohibited, and the Wastewater Utility Manager may take an enforcement action against a user for a bypass, unless:

         (a)   Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

         (b)   There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and

         (c)   The user submitted notices as required under division (C) above.

      (2)   The Wastewater Utility Manager may approve an anticipated bypass, after considering its adverse effects, if the Wastewater Utility Manager determines that it will meet the three conditions listed in division (D)(1) above.

POTW - WASTEWATER DISCHARGE PERMIT APPLICATION

§ 51.180 PURPOSE AND APPLICABILITY.

   The purpose of this section is to provide guidance for permit requirements §§ 51.183 through 51.187 will be applicable and immediately in effect when the IDEM relinquishes control of local pretreatment authority as described in 40 C.F.R. part 403. The effective date as used in this section will mean the date in which the city notifies the discharger of the change in local authority.

(Ord. 2008-38, passed 12-10-2008)

§ 51.181 WASTEWATER ANALYSIS.

   When requested by the Wastewater Utility Manager, a user must submit information on the nature and characteristics of its wastewater within 30 days of the request. The Wastewater Utility Manager is authorized to prepare a form for this purpose and may periodically require users to update this information. When such information is requested by other regulating authorities, the city shall be forwarded a copy of such submitted information.

§ 51.182 WASTEWATER DISCHARGE PERMIT REQUIREMENT.

   (A)   No significant industrial user shall discharge wastewater into the POTW without first obtaining a wastewater discharge permit from the Wastewater Utility Manager, except that a significant industrial user that has filed a timely application pursuant to § 51.183 may continue to discharge for the time period specified therein.

   (B)   The Wastewater Utility Manager may require other users to obtain wastewater discharge permits as necessary to carry out the purposes of this subchapter, state, or federal regulations.

   (C)   Any violation of the terms and conditions of a wastewater discharge permit shall be deemed a violation of this subchapter and subjects the wastewater discharge permittee to the sanctions set out in §§ 51.295 and 51.296. Obtaining a wastewater discharge permit from the city 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.
