Ms.Allen January 30,2006 PA-0500840(SA) Page 2 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 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: • 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 Structural Soil see http://www.hort.cornell.edu/uhi/outreach/csc/. For Tree Selection see http://www.ufei.org/. For Urban Forestry see http://www.coolcommunities.org, http://wcufre.ucdavis.edu and http://www.lgc.org/bookstore/energy/downloads/siv tree guidelines.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): - Increased energy efficiency(above California Title 24 Requirements) - See http://www.enemy.ca.gov/title24/. - Energy efficient widows (double pane and/or Low-E), lighting, appliances, heating and cooling systems, and programmable thermostats. See http://www.energystar.gov/ - Use Low and No-VOC coatings and paints. See South Coast's site for No-VOC Coatings at http://www.aqmd.gov/prdas/brGchures/paintguide.html - High-albedo (reflecting) roofing material. See http://eetd.lbl.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.harc.edu/harc/Proiects/CoolHouston/ and http://eande.lbi.gov/heatisland/ - Radiant heat barrier. See http://www.eere.energy.gov/consumerinfo/refbriefs/bc7.htmi - Install solar water-heating systems - Shading mechanism for windows, and porch, patio and walkway overhangs - Electrical outlets around the exterior of the unit(s) to encourage use of electric landscape maintenance equipment - Pre-wire the unit(s)with high speed modem connections/DSL and extra phone lines - 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/GreenBuildinq/, http://www.lgc.org, http://www.sustainable.doe.govl and http://www.consumerenergvicenter.ora/index.html • Diesel equipment should use verified alternative diesel fuel blends or Ultra Low Sulfur Diesel (ULSD). The California Air Resources Board (GARB) has verified specific alternative diesel fuel blends for NOx and PM emission reduction. Only fuels that have been certified by CARB should be used. For more information on alternative diesel blends, please call Mr. Chris Acree, Senior Air Quality Specialist, at (559) 230-5829. Information on biodiesel can also be found on the following CARB and EPA websites: http://www.arb.ca.govtfuels/diesel/altdiesel/altdiesel.htm and http://www.el)a.gov/oms/models/biodsl.htm.
