5.7 NOISE
<br /> The equipment that would be used in the proposed project is well balanced and is designed
<br /> to produce very low vibration levels throughout the life of the project. An imbalance could
<br /> contribute to ground vibration levels in the vicinity of the equipment. However,
<br /> vibration-monitoring systems installed in the equipment are designed to ensure that the
<br /> equipment remains balanced.Should an imbalance occur,the event would be detected and
<br /> the equipment would automatically shut down.Given these protective measures,impacts
<br /> related to ground and airborne vibrations will be less than significant.
<br /> 5.7.4 Cumulative Effects
<br /> A cumulative impact refers to a proposed project's incremental effect together with other
<br /> closely related past,present,and reasonably foreseeable future projects whose impacts may
<br /> compound or increase the incremental effect of the proposed project (Public Resources Code
<br /> §21083; California Code of Regulations,title 14, § 15064(h),15065(c),15130, and 15355).
<br /> In July 2008,21 projects were in various stages of progress with the City of Lodi. Most of
<br /> these projects are zoned residential,with a few office,mixed use,institutional,commercial,
<br /> and industrial projects proposed. All of these projects are more than 4 miles from the
<br /> proposed project,except for the improvements at the White Slough WPCF (Draft EIR issued
<br /> March 28,2008),which is adjacent to the project site (Bereket,2008;City of Lodi,2008).
<br /> In July 2008, 72 projects 1 were being processed with the San Joaquin County Building
<br /> Department. These projects were located in Acampo, Escalon,Farmington,French Camp,
<br /> Linden,Lodi,Lockeford,Manteca, Ripon,Stockton, and Tracy. The types of projects
<br /> included residential projects such as new residences,additions and remodels to existing
<br /> residences,mobile home renovations,and pool construction;commercial projects such as
<br /> administration buildings,barns, and a riding arena;light industrial projects such as storage
<br /> buildings, spray booths, and warehouses; office projects such as building conversions and
<br /> tenant improvements;and institutional projects such as classroom relocation and facilities to
<br /> house animals (Raborn,2008).
<br /> The only project identified within a mile of the LEC are the modifications to the neighboring
<br /> White Slough WPCF. Modifications include the addition of two aeration basins,a clarifier,a
<br /> digester,and some headworks and boiler room improvements. The addition of new"noisy'
<br /> process equipment was not included as part of this project. Given the distance to the
<br /> receptors and minimal noise associated from such facilities,a cumulative impact resulting
<br /> from the construction of the LEC and the proposed WPCF modification is not anticipated.
<br /> 5.7.5 Mitigation Measures
<br /> The LEC proposes to implement the following measures to ensure that any potential noise
<br /> impacts of the LEC are mitigated below the level of significance.
<br /> 5.7.5.1 Noise Hot Line
<br /> The applicant shall establish a telephone number for use by the public to report any
<br /> significant undesirable noise conditions associated with the construction and operation of
<br /> the project. If the telephone is not staffed 24 hours per day,the project owner shall include
<br /> 1 For the purposes of this discussion,San Joaquin County sorted its projects by project cost,and provided a list of the projects
<br /> costing$25,000 or more.
