San Joaquin Valley Air Pollution Control District Page 2 of 5 District Reference No: 20231043 November 10, 2023 Based on information provided to the District , Project specific annual criteria pollutant emissions from construction and operation are not expected to exceed any of the significance thresholds as identified in the District ' s Guidance for Assessing and Mitigating Air Quality Impacts ( GAMAQI ) : https : //www . valleyair . org /transportation / GAMAQI . pdf . 1a ) ConstrLmiroon rm= ons The District recommends , to reduce impacts from construction - related diesel exhaust emissions , the Project should utilize the cleanest available off- road construction equipment . 2 ) Vegetative Barriers and Urban Greening There are residential units located east of the Project . The District suggests the County consider the feasibility of incorporating vegetative barriers and urban greening as a measure to further reduce air pollution exposure on sensitive receptors ( e . g . , residential units ) . While various emission control techniques and programs exist to reduce air quality emissions from mobile and stationary sources , vegetative barriers have been shown to be an additional measure to potentially reduce a population ' s exposure to air pollution through the interception of airborne particles and the update of gaseous pollutants . Examples of vegetative barriers include , but are not limited to the following : trees , bushes , shrubs , or a mix of these . Generally , a higher and thicker vegetative barrier with full coverage will result in greater reductions in downwind pollutant concentrations . In the same manner , urban greening is also a way to help improve air quality and public health in addition to enhancing the overall beautification of a community with drought tolerant , low - maintenance greenery . 3 ) Clean Lawn and Garden Eajuipmen ire the Community Since the Project consists of residential development , gas - powered lawn and garden equipment have the potential to result in an increase of NOx and PM2 . 5 emissions . Utilizing electric lawn care equipment can provide residents with immediate economic , environmental , and health benefits . The District recommends the Project proponent consider the District ' s Clean Green Yard Machines ( CGYM ) program which provides incentive funding for replacement of existing gas powered lawn and garden equipment .
