§ 13.36.050. Wastewater discharge permit classification.¶
The director of utilities will classify all users in accordance with the principal activity conducted on the premises where the discharge occurs. The purpose of the classification is to facilitate regulation of discharges to the subregional system on the basis of each user's waste quality, quantity, flow, and city involvement; to provide an effective means of source control of toxic substances; and to provide a basis for sewer use charges to ensure an equitable recovery of capital and operating costs. User permit classifications are as follows:
A. Nonresidential User. Users that discharge nondomestic wastewater to the sanitary sewer system and do not meet the criteria of SIU.
B. Nonsignificant Categorical Industrial User. Defined in Section 13.34.030.
C. Significant Industrial User. As defined in Section 13.34.030.
D. Ongoing Groundwater Discharger. Users that discharge wastewater generated from groundwater remediation projects in excess of six months.
E. One-Time Discharger. Users that discharge wastewater generated as a result of purging monitoring wells, dewatering underground storage tanks, groundwater sampling, or for a variety of circumstances.
F. Waste Hauler. Haulers that discharge domestic septic waste, portable chemical toilet waste, nonhazardous commercial or industrial waste, groundwater remediation site waste, and/or landfill leachate at the POTW.
Residential users under normal circumstances will not be required to apply for or receive a wastewater discharge permit as defined in this title, providing that said user discharges only domestic wastewater.
