14.05.010 General.

Any requirement contained in this chapter may be incorporated as part of an industrial waste discharge permit and made a condition of issuance of such permit; may be required as part of a permit modification; or made a condition of the acceptance of the waste from a facility. Progress reports and compliance schedules shall be provided in accordance with the requirements established in Chapters 14.01 through 14.08. (Ord. 1676(part), 1992; Ord. 1618 §13(part), 1989).

14.05.020 Pretreatment facilities.

A. If treatment facilities, operation changes or process modifications at an industrial discharger’s facility are needed to comply with any requirements of Chapters 14.01 through 14.08 or are necessary to meet any applicable state or federal requirements, the manager/plant superintendent may require that such facilities be constructed or modifications or changes be made within a specified time period, taking into consideration construction time, impact of the untreated waste on the sewer system, economic impact on the facility, impact of the waste on the marketability of the treatment plant sludge, and any other appropriate factor.

B. Any facilities required to pretreat wastewater to a level acceptable to the plant superintendent shall be provided, operated and maintained at the user’s expense. Detailed plans prepared by a qualified professional engineer showing the pretreatment facilities, operating procedures and/or process modifications shall be submitted to and approved by the plant superintendent before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an acceptable effluent under the provisions of Chapters 14.01 through 14.08. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the plant superintendent prior to the user’s initiation of the changes. (Ord. 1676(part), 1992; Ord. 1618 §13(part), 1989).

14.05.030 Flow measurement and sampling facilities.

A. If so directed by the plant superintendent or manager, flow measurement, sampling devices, access facilities and related equipment shall be installed by the user discharging the waste, at the user’s expense, and shall be maintained by the user so as to be in safe condition, in proper operating condition at all times, and readily accessible to the requesting authority during periods of industrial activity of any type.

B. The flow measurement and sampling station shall be located and constructed in a manner acceptable to the requesting authority. Complete plans on all phases of the proposed installation, including all equipment proposed for use, shall be submitted to the plant superintendent for approval prior to construction. (Ord. 1676(part), 1992; Ord. 1618 §13(part), 1989).

14.05.040 Sampling manhole.

The manager/plant superintendent may require a discharger to install and maintain at the discharger’s expense a suitable manhole in the discharger’s branch sewer to allow observation, sampling and measurement of all industrial wastes being discharged into the sewer system. It shall be constructed in accordance with plans approved by the plant superintendent and shall be designed so that flow measuring and sampling equipment may be conveniently installed. Access to the manhole shall be available for monitoring purposes at all times when wastewater is being produced and/or discharged. (Ord. 1676(part), 1992; Ord. 1618 §13(part), 1989).

14.05.050 Grease traps and other pretreatment.

Grease, oil and sand traps shall be provided, operated and maintained when, in the opinion of the plant superintendent or manager, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand or other harmful ingredients; except that such traps shall not be required for private living quarters or dwelling units. All traps shall be of a type and capacity approved by the requesting authority and shall be located as to be readily accessible for cleaning and inspection. (Ord. 1676(part), 1992; Ord. 1618 §13(part), 1989).
