Section 3 - Pretreatment of Wastewater

3.4 Hauled Wastewater

A. Wastewater haulers shall have a valid wastewater hauler discharge permit before discharging wastes to the POTW. Each permitted wastewater hauling vehicle shall prominently display a number issued by the City on both doors of the vehicle cab. Such numbers shall be removable only by destruction.

B. Wastewater may be introduced into the POTW only at locations designated by the Superintendent, and at such times as are established by the Superintendent. Such waste shall not violate Section 2 of this Ordinance or any other requirements established by the City.

C. Prior to being issued a hauler discharge permit, the following conditions shall be met:

  1. Each truck shall have a sight glass calibrated in 100-gallon increments.
  2. Each vehicle shall be equipped to discharge at the location designated by the Superintendent without utilizing Utility equipment.
  3. Each vehicle shall maintain records evidencing the origin of the wastewater to be discharged and each driver shall record such information on forms provided by the Utility.

D. All procedures for discharging, for cleanliness, and for general sanitary operation on City property as described by the Utility shall be strictly adhered to by all wastewater haulers delivering wastewater to the designated Utility dumping station.

E. 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.

F. Wastewater from an industrial user shall identify in writing the type of industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.

G. In addition to remedies available to the Utility elsewhere in this ordinance, failure of a wastewater hauler to comply with the provisions set out herein shall be grounds for revocations of their hauler’s discharge permit by the Superintendent.

H. All hauled wastewater may be subject to sampling and analysis as may be required by the Superintendent.

3.3 Accidental Discharge/Slug Control Plans

At least once every two (2) years, the Superintendent shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Superintendent may require any user to develop, submit for approval, and implement such a plan. Alternatively, the Superintendent may develop such a plan for any user. 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 Superintendent of any accidental or slug discharge, as require by Section 6.6 of this ordinance; 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 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.

3.2 Additional Pretreatment Measures

A. Whenever deemed necessary, the superintendent may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewer, relocate and/or consolidate points of discharge, separate sewage waste stream from industrial waste streams, and such other conditions as may be necessary to protect the POTW and determine the user’s compliance with the requirements of this ordinance.

B. The Superintendent 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. Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.

D. Users which operate vehicular wash facilities shall provide, operate and maintain pretreatment facilities approved by the Superintendent to control solids and preclude the discharge of toxics to the POTW.

E. Users which operate food preparation facilities shall provide, operate and maintain pretreatment facilities approved by the Superintendent to control the discharge of greases, fats, oils and food solids to the POTW.

3.1 Pretreatment Facilities

Users shall provide wastewater treatment as necessary to comply with this ordinance and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in Section 2.1 of this ordinance within the time limitation specified by EPA., the State, or the Superintendent, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user’s expense. Detailed plans describing such facilities and operating procedures shall be submitted to the Superintendent for review, and shall be acceptable to the Superintendent 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 Utility under the provisions of this ordinance.
