DA Sanitary Sewer Diversion Capacities The Orange County Sanitation District has successfully implemented a dry weather urban runoff diversion program. In 2000, OCSD established the requirements for municipal dischargers requesting discharge of urban water runoff into OCSD facilities. The resolution set aside up to 10 MGD of surplus dry weather capacity for this purpose. Current OCSD policy provides for treatment at no charge for municipal discharges of dry weather urban mnof£ within the OCSD service area up to a cumulative volume of 4 million gallons per day for all dischargers within the service area. For this project, we expect OCSD will waive fees for the urban low flow runoff from the Della Channel.

U,& Required Environmental Documentation The City's proposed Santa Ana -Delhi Channel low flow diversion project will require California Environmental Quality Act (CEQA) clearance. Environmental impacts of the project would primarily be short -term, related to construction activities. Long term, the project will provide improvements to water quality in the channel and Upper Newport Bay. In addition to CEQA compliance, work in the channel w ll require regulatory permits from resources agencies with jurisdiction over the channel including the U.S. Army Corps of Engineers (USAGE), California Department of Fish and Wildlife (CDBX� and California Regional Water Quality Control Board (RWQCB).
