San Joaquin County May 21, 2001 <br /> Lockeford Oaks Page 2 <br /> the District's thresholds of significance for ozone precursor emissions as well as an <br /> overview of the regulatory environment governing air quality at the federal, state, and <br /> regional levels. The PM-10 Attainment Demonstration Plan - May 15, 1997 contains <br /> information and control strategies for PM-10. In addition, the District can provide air <br /> monitoring data and other relevant information. <br /> Section 2: Existing and Projected Emissions Levels <br /> The growth-inducing and cumulative impacts analyses should take into consideration <br /> the existing and planned development both within the project area and in the <br /> surrounding areas. The District recommends the use of the URBEMIS 7G modeling <br /> program to calculate the pollutant emissions resulting from motor vehicle trips <br /> generated by this development project. <br /> Additionally, the EIR should quantify emissions that are individually small but <br /> cumulatively significant sources of pollution. This includes, but is not limited to, <br /> emissions from natural gas combustion for space and water heating and emissions from <br /> gas-powered lawn and garden maintenance equipment. Emission factors for these <br /> sources of pollution are available from the South Coast Air Quality Management District <br /> CEQA Air Quality Handbook, the Sacramento Metropolitan Air Quality Management <br /> District, and from this District. <br /> Section 3: Mitigation Measures <br /> Mitigation measures must be included in the DEIR that reduce the emissions of reactive <br /> organic gases (ROG), nitrogen oxides, carbon monoxide, and PM-10 to the maximum <br /> extent feasible. Site design and building construction measures that would reduce air <br /> quality impacts should be included. In addition, Transportation Control Measures (TCM) <br /> should be stressed to the maximum extent feasible. District staff should be consulted <br /> for input on appropriate TCMs. <br /> If this project has been covered in a previous EIR that has addressed air quality issues <br /> please provide that information so that the District can make appropriate comments. <br /> Thank you for the opportunity to comment.
