(GX-94-1 ) <br /> Dear Mr. Martin: <br /> The San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) has <br /> reviewed the project referenced above and offers the following comments: <br /> San Joaquin Valley's air quality has been designated nonattainment by the EPA and <br /> the California Air Resources Board for the following pollutants, PM,o (fine particulate <br /> matter) and 03 (ozone). The California Clean Air Act (AB2595), requires areas that are <br /> designated nonattainment to reduce emissions 5% annually until standards are met. <br /> The District encourages the project proponent to take all feasible measures from the <br /> following list to reduce the amount of PM,o entrained as a result of the project. <br /> • All material excavated, graded or otherwise disturbed should be sufficiently <br /> watered to prevent excessive amounts of dust. Watering should occur at least <br /> twice daily with complete coverage, preferably in the late morning and after <br /> work is done for the day. <br /> • All clearing, grading, earth moving, or excavation activities should cease when <br /> wind speeds are equal to or greater than 20 mph. <br /> • On-site vehicle speed should be limited to 15 mph. <br /> David L Crow <br /> Executive Director.fir Pollution Control Officer <br /> Northern Region Central Region Southern Region <br /> ®�• ec �aec.c ea�ecer <br />
