a) Currently the applicant conducts the majority of its activities indoors at the material recovery building consisting of approximately 45,000square feet, including_the tipping,processing and transfer of municipal solid waste and non-recyclable residues for land-filling.The tipping,sorting and processing of recyclables;vehicles and equipment maintenance takes place in a separate building.The applicant proposes to continue the current operation.The ® applicant is currently permitted through San Joaquin Valley Air Pollution Control District (SJVAPCD) Permit# N-3187-4-0. b) The project is currently permitted under SJVAPCD Permit#N-3187-4-0.The applicant will. continue to work with the Air District on air quality issues.SJVAPCD has been sent a referral for further review. The applicant has prepared a number of studies to address emissions of various air c-e) pollutants, including greenhouse gas emissions.The net increase in daily and annual emissions of various air pollutants were compared with the thresholds of significance as adopted by the San Joaquin Valley Air Pollution Control District.The SJVAPCD has adopted thresholds of significance for two air pollutants.These air pollutants and the thresholds of significance are: Oxides of Nitrogen 10 tons/year,and Reactive Organic Gases 10 tons/year. The SJVAPCD has set a threshold for PM10 of 15 tons per year under their New Source Review Offset Requirements.The primary air quality study,which is entitled: Analysis of Air Quality Impacts from Mobile Sources,dated October 6, 2010 and which is available for review,concludes that emissions of various pollutants were evaluated from mobile sources associated with the proposed expansion at Tracy Material Recycling and Transfer Station. Comparisons of annual emissions with thresholds of significance indicate emissions from mobile sources would not lead to significant air quality impact. TIDe Green d.use Gas.Impact Assessment Baseline report submitted by the applicant on <Y. October 8, ."10 and which is;available for review indicates that the Greenhouse Gas Frrrissions,(GHG)are significantly avoided by increasing recycling and composting.. Tiie project will include composting as part of the overall operation. On July 8,2010 the applicant submitted an Odor Impact.Minimization Plan ( 1 P)to address possible odor impacts to surrounding neighbors..The OIMP indicated that the closest receptors will be operations.etaff and management during operating hours to monitor the compost materials handling operation.The site is located in rural San Joaquin County away from most sensitive _ receptors.Ta California Integrated Waste Management Board (now CalRecycle) has identified 1,000 feet as the distance required for identification of receptors.,The pro1ect site is surroundeck.by: 1) Lone Star Industries gravel mining operations on the adjacent parcel to fr the west; 2),Teichert Aggregates operation of a sand gravel mining facility tci the north; 3) two co residences (mobile homes) located approximately 600 feet north of the site on the east side of MacArthur Drive.There is also 1 residence approximately 1.4 miles south of the site oi5 the wesi-s'Ide of MacArthur Drive.The closest residential subdivision is approximately 1 mile north.of the site along MacArthur Drive.An analysis of prevailing wind.conditions for the site indl�ates wind is predominantly from the west,which could impact two residences northeast of the facility. However,the compost facility is located 30-40 feet below grade because it.ip,sited within a depression from a closed gravel quarry.This would tend to mitigate the transfer.of odors;to surrounding properties.The following mitigation measures dgveloped.(jy.the GIMP and it-hich:will be included in the conditions of approval for the project are as follows: 1) Operator to maintain an updated GIMP; 2)Compost feedstock shall by:process-0 within.7 days of receipt,and commercial food waste shall be processed within 4$,hours o0pcelpt;3) Commercial food waste composted on-site shall use the covered aerated stdic.pile.system,that encompasses the compost feedstock and forces air through a bio-filter to minimize odor generation;4) Compost operations shall occur on a paved surface to minimize.lionding and anaerobic conditions that could generate odors;and Compost i4fridrow shall not be,turned.when winds exceed 25 miles per hour to minimize odor g neration.,.These mitigation:.measures are expected to reduce the odor impacts to less than significant. Constructlq�n.activities assoc'lated with the proposed project could generat6.short-term emissions:#)at exceed the SJVAPCD threshold criteria and contribute to the•nonattainment designatior;.of the San Joagyjn Valley Air Basin-for ozone and particulate ..,_ F p:
