5.5 HAZARDOUS MATERIALS HANDLING
<br /> 5.5.3 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 /> Existing laws and regulations address the handling of hazardous materials and the
<br /> transportation and use of anhydrous ammonia,an acutely hazardous material, and will
<br /> ensure that all hazardous materials at the LEC are safely managed. The existing STIG plant
<br /> and the LEC Plant plan to share the existing anhydrous ammonia aboveground storage
<br /> tank. There are no reported additional properties adjacent to the LEC that use anhydrous
<br /> ammonia, so that a simultaneous release of this chemical from two or more sources would
<br /> not cause a hazardous cumulative concentration of this chemical. Existing laws and
<br /> regulations will thus ensure that the proposed project's incremental effect is not
<br /> cumulatively considerable.
<br /> 5.5.4 Mitigation Measures
<br /> The following sections present measures included in the project to mitigate potential public
<br /> health and environmental impacts of handling hazardous materials and regulated
<br /> substances during construction and operation.
<br /> 5.5.4.1 Construction Phase
<br /> The hazardous materials that would be used during construction present a relatively low
<br /> public health risk,but could contaminate surface water or groundwater if a release
<br /> occurred. Use of BMPs would reduce the potential for the release of construction-related
<br /> fuels and other hazardous materials to stormwater and receiving waters as discussed in
<br /> Section 5.15,Water Resources. BMPs prevent sediment and stormwater contamination from
<br /> spills or leaks,control the amount of runoff from the site, and require proper disposal or
<br /> recycling of hazardous materials.
<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.
