and provide sufficient thickness for plant growth. Best management practices will be employed to <br />prevent deposit of silt into the wetlands from the landscaped areas. <br />Although the selected species are drought tolerant, the relatively thin layer of soil in which they <br />will be planted will require permanent irrigation. It is contemplated that the plants will be irrigated <br />once a week in the hot season during the first year, once every two weeks or as needed <br />thereafter. <br />Planting will be successful if 85% of the plants survive. Plants will be replaced to maintain at <br />least this success rate. <br />Landfill closure landscaping will also be guided by a licensed landscape architect. Such <br />landscaping will be in accordance with the regulations governing landfill closure and the <br />preliminary Closure / Postclosure maintenance plan. At this time, that Plan identifies final surface <br />as un -irrigated open space. <br />3. Schedule <br />In accordance with the EIR Findings of Impact (Page 5 of 13), the vegetation will be planted <br />within one year of the approval of the project [SWFP revision]. <br />4. Verification <br />The implementation of this Measure will be verified visually. <br />5. Reporting Requirements <br />At this time, it is contemplated that planting the screening vegetation will be by a contractor <br />selected by competitive bid. A copy of the plans and specifications will be forwarded to the Local <br />Enforcement Agency (LEA - San Joaquin County Environmental Health Department) to document <br />the planting. <br />B. AIR -1: AIR QUALITY IMPACTS <br />Conditions <br />Impact to Air quality is anticipated due to the increase in traffic resulting from increasing the daily <br />limit of incoming refuse vehicles and from increased use of landfill equipment resulting from the <br />placement of increased refuse tonnage. Of concern was the production of particulates (PM -10) <br />and oxides of nitrogen (NOx). <br />The Draft EIR (page 3.1-16) states that the County would conduct an air impact assessment as <br />reauired by San Joaauin Vallev Unified Air Pollution Control District (SJVAPCD) Rule 9510 <br />(emphasis added). However, Section 4.4.3.11 of SJVAPCD exempts sanitary landfills such as <br />Mitigation Monitoring Plan 3 North County Recycling Center and Landfill <br />April 3, 2009 San Joaquin County Public Works/Solid Waste <br />
