§ 28-154. Pretreatment of wastewater.

(a)

Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this article and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in section 28-152 of this article within the time limitations specified by the EPA, the state, or the city, 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 public works director for review, and shall be acceptable to him or her 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 city under the provisions of this article.

(b)

Accidental discharge/slug discharge control plans. The public works director shall evaluate whether each significant industrial user needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The public works director may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. Alternatively, the public works director may develop such a plan for any user. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:

(1)

Description of discharge practices, including nonroutine batch discharges;

(2)

Description of stored chemicals;

(3)

Procedures for immediately notifying the public works director of any accidental or slug discharge, as required by subsection 28-148(f) of this article; and

(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 runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and measures and equipment for emergency response.

(d)

Hauled wastewater.

(1)

Septic tank waste may be introduced into the POTW only at locations designated by the public works director, and at such times as are established by him or her. Such waste shall not violate sections 28-136 through 28-144 of this article or any other requirements established by the city. The public works director may require septic tank waste haulers to obtain individual wastewater discharge permits.

(2)

The public works director may require generators or haulers of industrial waste to obtain individual wastewater discharge permits or prohibit the disposal of hauled industrial waste. The discharge of hauled industrial waste is subject to all other requirements of this article.

(3)

Industrial waste haulers may discharge loads only at locations designated by the public works director. No load may be discharged without prior consent of the director. The director may collect samples of each hauled load to ensure compliance with applicable standards. The director may require the industrial waste hauler to provide a waste analysis of any load prior to discharge.

(4)

Industrial waste haulers must provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the industrial waste hauler, permit number, truck identification, names and addresses of sources of waste, and volume and characteristics of waste. The form shall identify the type of industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
