SECTION 1.0:EXECUTIVE SUMMARY will have no significant adverse impact on air quality or public health. See Section 5.1 of this AFC for a detailed analysis of air quality and Section 5.9 for public health. In August 2006,the California legislature passed Assembly Bill (AB) 32,the California Global Warming Solutions Act of 2006. AB 32 requires California resource agencies to establish a comprehensive program of regulatory and market mechanisms to achieve reductions in greenhouse gas emissions. The LEC helps to meet the goal of minimizing greenhouse gas emissions by providing efficient combined-cycle power and electrical reliability for project participants,thereby reducing the need for participants to build smaller,less efficient projects. By locating power plants near the load,total emissions of carbon dioxide are reduced, thereby decreasing the global warming impacts of electric generation. Improved efficiency means reduced emissions per unit of electricity generated. In addition,the project meets or exceeds the SB1368 CO2 performance standard. 1.5.2 Biological Resources The LEC will be located between the WPCF and existing STIG plant in an area currently used as equipment storage for the WPCF. The project site does not contain any wetlands or suitable habitat for sensitive plant or wildlife species and would not cause an adverse impact to sensitive biological resources. The California-threatened Swainson s hawk and a nesting white-tailed kite were observed in the vicinity of the project site during field surveys, and native and non-native trees located in the laydown areas could provide suitable nesting habitat for raptors and other migratory bird species. No aquatic habitat is present in the project area;however,a large irrigation canal just south of the property could provide suitable habitat for species such as the western and northwestern pond turtle and the giant garter snake. The Applicant will mitigate these effects in accordance with the California Department of Fish and Game policies and guidelines by conducting preconstruction surveys to determine the presence/absence of any of these species on the project site or laydown areas. In addition,the project site does not contain wetlands or federally listed species and will not require federal permits for wetlands or endangered species. Section 5.2 discusses biological resources. 1.5.3 Noise The City of Lodi maintains a nighttime noise standard of 5 A-weighted decibels (dBA) or less above the nighttime ambient (Leq) levels. The Applicant conducted 25-hour ambient noise monitoring at the project site and also prepared a noise generation model for the LEC. The predicted plant noise level is less than 45 dBA at all receptors. The resulting increase is 5 dBA or less above the existing L9o. This is within the CEC Staff's guideline that a 0 to 5 dBA increase in an area's background noise,measured as the average L90 of the four quietest nighttime hours and would not represent a significant adverse impact. Section 5.7, Noise,contains a discussion of the noise assessment. 1.5.4 Visual Resources The LEC project will be sited in an existing industrial development including the STIG plant and the WPCF. The most prominent visual features of the LEC will be the stack, at 150 feet. Analysis of simulated views of the project from sensitive viewing positions (key observation points) shows that the project would not cause adverse visual impacts.
