f 1998 1993 North of Landfill 69 69 South of Landfill 68 69 The noise levels are essentially unchanged over a+5-year period. There continues to be no definitive noise "signature"associated with landfill traffic in that landfill traffic volumes on Austin Road are higher north of the landfill than to the south, but noise levels are approximately equal in either direction from the landfill entrance. Regulations Plans, and Policies Noise regulations, plans, and policies have not change substantially since certification of the Austin Road Landfill EIR (1994). San Joaquin County is currently in the process of adopting a new County noise ordinance. The County noise ordinance creates the following noise performance standards (dBA) at any "outdoor activity area"such as rearlside yards of residences: 7 a.m.— 10 P.m. 10 p.m.—7 a.m. Average Level(Leq) 50 45 Maximum Level(Lmax) 70 65 The FEIR was based upon project compliance with the City of Stockton noise standards, which are as follows(dBA): 7a.m.-10 .m. 10p.m.-7a_m. Average Level(Leq) 55 45 E Maximum Level(Lmax) 75 65 The daytime standards under the new County ordinance are.5 dB more stringent that the City standard. The FEIR identifies noise levels exceeding the City ordinance level as a potentially significant impact. Although the new County noise standard is 5 dB more stringent,there is no jurisdictional change associated - with project implementation. Continued compliance with Mitigation Measures H.1(a) and H.1(b) will maintain a less-than-significantnoise impact. Traffic Data Update Updated traffic noise studies in the BNSF Intermodal Facility Noise Report(1999)show a future traffic noise level of 74 dB Ldn between 2000 and 2010 at 50 feet from the Austin Road centerline north of the landfill entrance. Table III.H.4 of the FEIR shows a traffic noise level of 74 dB Ldn in 2005. There have been no new data that would indicate that FOR traffic noise estimates do not continue to be valid. Baseline conditions have not changed, significance criteria and associated mitigation measures are still valid, and new data on traffic conditions does not measurably alter previous conclusions reached in the FEIR. There are no new impacts not previously adequately discussed in the FEIR. The project sponsor shall conduct a bird survey before construction of the project and monitor bird population after operation of the landfill expansion begins. The bird monitoring will be part of the Wildlife _ San Joaquin County GP-99-7, ZR-99-6, UP-99-17, ER-99-21City of Stockton Page 19 Community Development
