amount of average dry weather flow being treated at the RWCF is approximately 30 MGD during the noncanning season and 38 MGD during the canning season. The City has initiated the construction of a six-staged plant expansion program at the RWCF to increase the overall treatment plant capacity. Under the expansion program, the R WCF would be capable of treating 42 MGD by December 2003. Sewer lines are in place to collect sewage flows from the existing facilities, and sewer lines would be extended from the line located north of the project site (at Arch-Sperry Road and Alitalia Avenue) to accommodate the sewage flow that would be generated in the future development areas (Reinard W. Brandley, Consulting Airport Engineer 1997).

However, this impact is considered less than significant under both Phase I and Phase 2 interchange conditions for the following reasons: ■ an expansion program is underway at the RWCF that can accommodate the proposed project and approved but unconstructed project to be serviced by the facility, ■ the County will pay applicable connection fees, in accordance with existing City/County agreements, and a the County has agreed to pay in-lieu fees established for Community Facilities District 90-1, in accordance with existing City/County agreements. Mitigation Measure None required. Impact PS-6: Increased Generation of Solid Waste The proposed project would result in the generation of approximately 34.43 tons per day(tpd) of solid waste under 2015 conditions with Phase 1 improvements and 36.19 tpd under project conditions with Phase 2 improvements. Because the County landfills have adequate capacity to accommodate the anticipated solid waste that would be generated by the proposed project (Reinard W. Brandley, Consulting Airport Engineer 1997) under both phases, this impact is considered less than significant under both Phase 1 and Phase 2 interchange conditions. 1 ' k • ' Stockton Metropolitan Airport Project Chapter 10.
