STATEMENT OF FACTS:
1. King County has had a long-term combined sewer overflow ("CSO") control plan since 1979. The long-term CSO control plan was last amended in 1999 as part of the regional wastewater services plan that was approved through Ordinance 13680.

Eight of these twenty-two CSO outfall locations not associated with satellite CSO treatment plants currently have projects underway or are early action projects. Three of the eight CSO outfall locations (CSO outfalls 009, 027a and 037) are being adjusted for full control. Of the twenty-two CSO outfall locations that are not controlled to Ecology's standard, the remaining fourteen CSO outfall locations require future capital projects and are the subject of the King County's long-term CSO control plan amendment.
