The CBC noise generators are approximately 140-feet from the <br /> east property line, 190-feet from the west property line, <br /> and 445-feet from Navy Drive. Based on a 6 dBA reduction of <br /> noise with each doubling of distance from the noise source, <br /> the project will generate approximately 83 dBA at the east <br /> property line and 81 dBA at the west property line. The <br /> noise level at the Navy Drive property line will be within <br /> the industrial noise limit of 75 dBA at the property line. <br /> Given the fact that the project site is within an industrial <br /> area, adjacent properties may not be adversely affected by <br /> the excessive noise created by the CBC units . Should com- <br /> plaints arise, it will be necessary to baffle or enclose the <br /> equipment so as to reduce the noise levels at the property <br /> lines to 75 dBA. <br /> The most sensitive noise receptor in the area is the Trinity <br /> Presbyterian Church located at the intersection of Navy <br /> Drive and Pershing Avenue, approximately 2 , 500 feet from the <br /> project site . This distance factor, along with other noise <br /> generators in proximity to the church, will eliminate any <br /> noise impact of the project on the church. <br /> Mitigation Measures: <br /> a. The project should comply with the noise standards <br /> outlined in Title 24 of the California Code of Regulations <br /> and the Occupational Safety and Health Administration (OSHA) <br /> Noise Compliance Guidelines. <br /> b. If warranted by noise complaints, noise attenuation <br /> walls should be constructed along the east and west property <br /> lines to reduce the on-site noise levels to 75 dBA at the <br /> property line. <br /> 6 . Energy/Natural Resources <br /> Use of Substantial Amounts of Energy <br /> Setting: <br /> The project at full operation (both CBC units) will require <br /> approximately 180 Therms per hour of natural gas. This is <br /> equivalent to the average natural gas usage of 820 single- <br /> family residential dwellings during one year . <br /> Analysis: <br /> Although the project will consume a significant amount of <br /> natural gas, Pacific Gas and Electric Company, as the serv- <br /> ice provider, has indicated they have the ability to provide <br /> service with existing gas transmission facilities in the <br /> area. <br /> Mitigation Measures: <br /> None proposed. <br /> 24 <br />
