(1) If treatment facilities, operation changes, or process modifications at a user’s facility are needed to comply with any requirements of this chapter or are necessary to meet any applicable State or Federal requirements, the WRD Manager 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 or reclaimed wastewater, and any other appropriate factor.

(2) Any facilities required to pretreat wastewater to a level acceptable to the WRD Manager shall be provided, operated, and maintained at the user’s expense. Detailed plans showing the pretreatment facilities, operating procedures, and/or process modifications shall be submitted to and acceptable to the WRD Manager 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 discharge under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the WRD Manager prior to the user’s initiation of the changes.
