MBA will discuss the need to afnend KRC s National Pollution'Discharge Elimination System (NPDES) permit for industrial activities (W;DR.No.,5=Q1=14.5). MBA.Will evaluate`the potential for water.,quality impacts based on,guideN sand policie`s'of the Regional Water'Quality Control Board (RWQCB);the U S Environmental-Protection Agency`(EPA); and:any local agencies regarding watee quality;irrrpacts from storm water runoff an'd Wash-water collection.

The resulting level of significance will.be-clearly identified prior to, and following application of mitigation measures. r Air Quality 4 The project area is located in a rural portion of San Joaquin Countywhere air quality is affected primarily by pollutant transport from upwind areas, and local emission sources including vehicles traveling along local.roadways (e.g., State Highway 12) and agricultural operations. The principal air quality issues related to the Project would include the long-term impacts associated with increasing the number of motor vehicle trips, primarily diesel, in the area, stationary emissions associated with the operation of the aggregate plant, and fugitive dust from excavation. San Joaquin County is part of the San Joaquin Valley Air Basin and is currently in serious nonattainment for the eight-hour federal standard for ozone and inhalable particulate matter ` (PM10).. .The Project area is also in nonattainment for the federal standard for fine i particulate matter (PM2.5). The Project area was in extreme nonattainment for the one-hour standard for ozone prior to the standard's revocation in June 2005. E j 3 MBA will briefly summarize prevailing .climatic and meteorological characteristics of the area based on available published sources, and discuss how these characteristics relate to air quality. MBA will characterize existing emissions sources (including sources of odorous emissions, if applicable) within and around the proposed project and stationary sources in the immediate area. This will require the-identification of air-pollutant sensitive land uses or activities within the project area. MBA will describe current air quality conditions in the vicinity of the property.based on monitoring data compiled by the California Air Resources Board and the SJVAPCD and discuss air pollutant trends based on SJVAPCD emissions inventories and projections. This will include a discussion of the existing regulatory context, including relevant air quality legislation, air quality standards, and regulatory agencies. MBA will identify applicable goals and policies within the state-mandated Clean Air Plan that would apply to the project. { The air quality analysis will be comprehensive including an evaluation of both localized and regional air quality impacts. MBA will assess stationary, area, and mobile source emissions generated during both the construction and operation phase of the project. The analysis will use the procedures and thresholds in the Guide for Assessing and Mitigating Air Quality Impacts (GAMAQI), published by the San Joaquin Valley Air Pollution Control District (SJVAPCD), as well as the ambient air quality standards. A consistency determination will be prepared in accordance with CEQA guidelines and included to ensure that the project is consistent with the goals of the Extreme Ozone Attainment Demonstration Plan and 2003 PM10 Attainment Plan. MBA will quantify emissions from the existing operation to characterize baseline conditions and allow for the quantifications of the Project's net air quality impacts. Project emissions I
