111. AIR QUALITY <br /> a. Less than SignHieant Impact: San JoagUill Valley Air Pollution Ccultrol District staff (T. <br /> Bettencourt, 1999) has reviewed the u-,e permit application and ctsncluded as follows: <br /> "Provided that this operation and the proposed <br /> expansion are consistent With the. E1R prepared fur <br /> this project and the_ facility is in compliance with all <br /> .District rules and regulations, it appears that this <br /> project will have a less-than-Significant impact un <br /> air qualitN,." (Jule 29, 1999). <br /> ' n <br /> The FEIR identifies the San Joaquin Valley Air Basin as being in n()n-atta1jlment for ozone and <br /> 10-micron diameter or less particulate matter (PM-10). As of 1999, the attai.nnient status of these <br /> two pollutants is unchanged. l=missioi1s reductions iii nisn-attainment areas must be <br /> implemented until standards are met. <br /> A new cycle of air quality planning has been completed Subsequent to the FEIR certification. <br /> The currently approved air quality plan, identified as the "Ozone Attainment Demonstration <br /> Plan" and "PM-10 Attainment Demonstration Plan":includes attainment strategies for PM-10 as <br /> well as for ozone. A new federal standard for ultra-tiiiie diameter particulates of 2.5 micron in <br /> diameter or smaller Was promulgated in 1997 (called "PM-2.5"). implementation of this <br /> standard is on-hold pe11ding the outcome of legal challenges. Baseline data acquisition fc�r PM- <br /> 2.5 is continuing, but any planning activities relative to this new standard will be several years <br /> away, if they- occur at all. <br /> Since the FEIR ,vas certified, a requirement for landfill gas er3ii55icsri5 control for landfills <br /> exceeding certain size thresholds �n'as promulgated under Federal ]a��.. The project, %with the <br /> system developed in conjunction with landfill expansion. meets Or exceeds federal <br /> requirements. <br /> As part of the PM-10 attainment strategy, the San Joaquin Vallee APCD developed and <br /> updated/revised Regulation Vill (Fugilk e Dust .Proliibition4). Regulation Vlll corers a wide <br /> variety of dust-generation activities from general soil disturbance to specific operations such'as <br /> landfilling. The FEIR acknowledges Pule 8040 specificallN, applicable to landfills. With <br /> compliance ith SJVAPCD rule-, and regulations regardin fugitive dust control and LFG <br /> w <br /> collection/disposal, landfill operations impact will be less than significant. <br /> Potentially significant impacts front fugitive dust during landfilling and from odors associated <br /> 4 <br /> with landfill gas were identified in the FEIR. Adverse, but less-than-Significant impacts were <br /> identified from on-site equipment exhaust, increased LFG generation, toxic air contaminants <br /> within LFG, and vehicular travel were identified. Installation of an LFG collection system and <br /> operational procedures (Mitigation Measure G.5) were specified for LFG en-tissions/odor <br /> impact mitigation. Compliance with Rule 8040 is considered equivalent to Mitigation Measure <br /> G.I. Rule 8040 requires the 1`0110%,ving: <br /> lalstaliation of liners, constc•uction Of.ne"w landfill cell; - <br /> effective bust suppression utilizing Nwater, pre-soaking, wetting agents or other <br /> surfactants. <br /> -1�- <br />
