Body
BE IT ORDAINED BY THE COUNCIL OF KING COUNTY:
SECTION 1. Findings.
A. The metropolitan King County council adopted the Regional Wastewater Services Plan (RWSP) by Ordinance 13680 on November 29, 1999. The RWSP set forth policies intended to guide the county in providing wastewater treatment at its existing plants and in expanding treatment capacity through the year 2030. In treatment plant policy 4 (TPP-4), the RWSP calls for King County to establish goals for odor control at all treatment plants and calls for the executive to investigate potential technologies and costs for odor control and recommend a policy so that odors are controlled at existing plants and any new plant.
B. In accordance with TPP-4 King County has investigated odor control and prevention and measurement technologies and costs. An evaluation was performed on the West Point Plant and South Plant and their associated odor control systems, maintenance practices and operating data. A series of six odor control workshops were held in March and April 2002 regarding state of the art odor prevention and control. Engineering, public outreach, and operations and management staff from the county's wastewater treatment division participated in these workshops along with outside engineering experts. As a result of these efforts, King County defined the odor control prevention levels currently achieved by the county's existing treatment plants and those that are achievable.
D. The executive's recommended odor control policies as called for in TPP-4 of Ordinance 13680 are included in this ordinance.
