Mr. Griffin October 10, 2005 PA-0500647(SA) Page 2 Rule 4101 (Visible Emissions)This rule prohibits emissions of visible air contaminants to the atmosphere and applies to any source operation that emits or may emit air contaminants. The applicant is must contact the District's Small Business Assistance Office at(209) 557-6446 to receive additional information/instructions. Rule 4102 (Nuisance)applies to any source operation that emits or may emit air contaminants or other materials. In the event that the project or construction of the project creates a public nuisance, it could be in violation and be subject to District enforcement action. The District encourages innovation in measures to reduce air quality impacts. There are a number of features that could be incorporated into the design/operation of this project to provide additional reductions of the overall level of emissions. (Note: Some of the measures may already exist as County development standards. Any measure selected should be implemented to the fullest extent possible.) The suggestions listed below should not be considered all-inclusive and remain options that land-use authority should consider: • The applicant/tenant(s) should require that all diesel engines be shut off when not in use on the premises to reduce emissions from idling. • Enhanced 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). — 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. 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)230-5800 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, eorgia A Stewart Air Quality Specialist Central Region C:File
