7.04.280 Nondomestic Sewage Restricted.
A. Permission to discharge into the sanitary sewer system of the District anything but domestic sewage will be granted only in accordance with, and in consideration of, the conditions of each case, and shall be subject to reasonable rules, regulations and requirements to prevent excessive alkalinity or acidity of the effluent or excessive discharge of organic or inorganic substances in solution or suspension, whether liquid, semisolid or solid.
B. Pretreated purge water from soil/groundwater remediation shall be accepted approval by the District upon prior approval by the District. The following must be performed prior to acceptance:
1. A letter from the contractor, requesting discharge and describing the general characteristics of the purge water, must be submitted to the District. The letter must further describe the method of discharge and the type of pretreatment proposed prior to discharge.
2. A discharge permit must first be issued by the District which will specify the volume of water, either in batch volume amounts for the year, or total quantity allowed for the year. The permit will state the parameters for which the purge water must be tested. Reference is made to Section 7.04.330, Preliminary treatment and control, which requires additional treatment to meet discharge standards prior to actual discharge. A permit fee of one hundred fifty dollars, collected at the time of permit issuance, will be charged for each separate location and for each year the discharge occurs. Actual volumes of discharge will be monitored by the District and charged in units of HCF (hundred cubic feet). The sewer service charge for each HCF will be in accordance with the current sewer service charge rate in effect for that fiscal year. Payment for sewer service charges shall be paid on a yearly basis and becomes due and payable at the time of notification by the District.
C. Actual discharge will not be permitted until results from testing have been received and the results are acceptable to the District. A visual inspection of the contained purge water will then be performed by the District prior to granting discharge. Technology for the pretreatment of wastewater shall be referenced to 40 CFR Parts 405 through 471. (Ord. 101 §1, 2001; Ord. 89 §1, 1996; Ord. 72 §1, 1991; Ord. 64 §2; Ord. 37 §2, 1983; Ord. 3 §5.2, 1973)
