Ms.Allen Smotember 14,2005 PA-0500583 GP Page 4 - Use Low and No-VOC coatings and paints. See South Coast's site for No-VOC Coatings at http://www.aqmd.gov/prdas/brochures/paintguide.html - Cool Paving. "Heat islands" created by this and similar projects contribute to the reduced air quality in the valley by heating ozone precursors. See http://www.harc.edu/harc/Projects/CoolHouston/ and http://eande.lbl.gov/heatisland/ - Radiant heat barrier. See http•//www.eere.energy.gov/consumerinfo/refbriefs/bc7.htmi - Exits to adjoining streets should be designed to reduce time to re-enter traffic from the project site - More information can be found at: http://www.ciwmb.ca.gov/GreenBuilding/, http://www.lgc.org, http://www.sustainable.doe.gov/, htti)•//www.consumereneroycenter.org/index.htmI • Project design should use models put forward by the Local Government Commission (LGC) in the "Smart Growth Guidebook," such as; street block patterns that form an interconnected grid, short block faces, numerous alleys and narrow streets. The LGC website http://www.lgc.or(I contains valuable information and resources on subjects from street design to energy efficiency. • The applicant should implement measures to reduce the amount of vehicle traffic to and from the residential area(s) that further reduce air pollution in the valley. This could include providing an information center for residents to coordinate carpooling. Check out the"Spare the Air'section of our website www.vallevair.org • Construction activity mitigation measures include: - Install sandbags or other erosion control measures to prevent silt runoff to public roadways from sites with a slope greater than one percent - Limit area subject to excavation, grading, and other construction activity at any one time - Limit the hours of operation of heavy duty equipment and/or the amount of equipment in use - Replace fossil-fueled equipment with electrically driven equivalents (provided they are not run via a portable generator set) - Require that all diesel engines be shut off when not in use on the premises to reduce emissions from idling. - Curtail construction during periods of high ambient pollutant concentrations; this may include ceasing of construction activity during the peak-hour of vehicular traffic on adjacent roadways, and "Spare the Air Days"declared by the District. - Implement activity management(e.g. rescheduling activities to reduce short-term impacts) - During the smog season (May through October), lengthen the construction period to minimize the number of vehicles and equipment operating at the same time. - Off road trucks should be equipped with on-road engines when possible. - Minimize obstruction of traffic on adjacent roadways. - Light Duty Cars and Trucks should be alternative fueled or hybrids. District staff is available to meet with you and/or the applicant to further discuss the regulatory requirements that are associated with this project. If you have any questions or require further information, please call me at (559) 230- 5844 or Mr. Hector R. Guerra, Senior Air Quality Planner, at (559) 230-5820 and provide the reference number at the top of this letter. Sincerely, q. . . 1. __N �,p W 0 ssica R.
