Ms.Allen September 22, 2005 PA-050054 `„y� Page 2 Rule 8071 (Unpaved Vehicle/Equipment Traffic Areas) limits fugitive dust emissions from unpaved vehicle and equipment traffic areas. 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. Rule 4601 (Architectural Coatings) limits volatile organic compounds from architectural coatings. This rule specifies architectural coatings storage, clean up and labeling requirements. Rule 4602 (Motor Vehicle and Mobile Equipment Refinishing Operations) regulates the finishing and refinishing of Group I and Group II motor vehicles and Equipment. Such vehicles include (but are not exclusive to) passenger cars, large/heavy duty truck cabs and chassis, light and medium duty trucks and vans, golf carts and motorcycles, buses and mobile equipment. Rule 4641 (Cutback, Slow Cure, and Emulsified Asphalt, Paving and Maintenance Operations). if asphalt paving will be used, then paving operations of this project will be subject to Rule 4641. This rule applies to the manufacture and use of cutback asphalt, slow cure asphalt and emulsified asphalt for paving and maintenance operations. 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 the agency with the land-use authority should consider for incorporation into the project. • Trees should be carefully selected and located to protect the building from energy consuming environmental conditions, and to shade paved areas. Trees should be selected to shade paved areas that will shade 50% of the area within 15 years. Structural soil should be used under paved areas to improve tree growth. For information on structural soil see http://www.hort.cornell.edu/uhi/ outreach/csc/. For information on tree selection see http://www.ufei.org/. For urban forestry see http:/Avww.coolcommunities.org, http://wcufre.ucdavis.edu, and http://www.lac.org/bookstore/energ downloads/siv treeguidelines.pdf. • As many energy conserving and emission reducing features as possible should be included in the project. Energy conservation measures include both energy conservation through design and operational energy conservation. Examples include(but are not limited to): - !nemased energy-efficiency(above California Title 24 Requiremerrts). See http://www.energy.ca.gov/title24/. - Energy efficient widows (double pane and/or Low-E) - Use Low and No-VOC coatings and paints. See South Coast's site for No-VOC Coatings at http://www.aqmd.clov/prdas/brochures/paintguide.html - High-albedo (reflecting)roofing material. See http://eetd.lbi.gov/coolroof/ - 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.eere.ener_qv.gov/consumerinfo/refbriefslbc7.htmi - Energy efficient lighting, appliances, heating and cooling systems. See http://www.eneraystar.gov/ - Install solar water-heating system(s) - Install photovoltaic cells - Programmable thermostat(s)for all heating and cooling systems - Awnings or other shading mechanism for windows - Porch, patio and walkway overhangs - Ceiling fans, whole house fans - Utilize passive solar cooling and heating designs. (e.g. natural convection, thermal flywheels)
