Ms.Hatef ...- March 6,2006 PA-0600068(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. Rule 9510 (Indirect Source Review)This rule requires the applicants of certain development projects to submit an application to the District when applying for the development's last discretionary approval. The rule requires developers to mitigate emissions at the project site to mitigate emissions at the project site to the extent feasible and to pay a mitigation fee to the District for a percentage of the remaining emissions. The ISR rule becomes effective March 1�', 2006. Projects that have not received a final discretionary approval by March 1, 2006 must submit an ISR application by March 31, 2006. The District encourages innovation in measures to reduce air quality impacts. There are a number of features that could be incorporated into the construction of this project to provide additional reductions of the overall level of emissions. The suggestions listed below should not be considered all-inclusive and remain options that the agency with the land-use authority should consider: • Diesel equipment should use verified alternative diesel fuel blends or Ultra Low Sulfur Diesel (ULSD). The California Air Resources Board (CARB) 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.gov/fuels/diesel/altdiesel/altdiesel.htm and htto://www.epa.clov/oms/ models/biodsl.htm. • The applicant should use diesel equipment fueled by alternative diesel fuel blends or Ultra Low Sulfur Diesel (ULSD). The California Air Resources Board (CARB) has verified speck alternative diesel fuel blends for NOx and PM emission reduction. Only fuels that have been certified by CARB should be used. Information on biodiesel can be found on CARB's website at http://www.arb.ca.gov/ fuels/diesel/altdiesel/altdiesel.htm and the EPA's website at http://www.ei)a.00v/oms/models/ biodsl.htm. The applicant should also use CARB certified alternative fueled engines in construction equipment where practicable. Alternative fueled equipment may be powered by Compressed Natural Gas (CNG), Liquid Propane Gas (LPG), electric motors, or other CARB certified off-road technologies. To find engines certified by the CARB, see their certification website http7//www.arb.ca.gov/msprog/offroad/cerUcert.php. For more information on any of the technologies listed above, please contact Mr. Chris Acree, Senior Air Quality Specialist, at (559)230-5829. • Construction equipment should have engines that meet the current off-road engine emission standard (as certified by the CARB), or be re-powered with an engine that meets this standard. Tier I, Tier II and Tier III engines have significantly less NOx and PM emissions compared to uncontrolled engines. To find engines certified by the CARB, see http://www.arb.ca.gov/mspro(l/offroad/cert/cert.php. This site lists engines by type, then manufacturer. The "Executive Order" shows what Tier the engine is certified as. Rule 9510 requires construction exhaust emissions to be reduced by 20 percent for NOx and 45 percent for PM10 when compared to the statewide fleet average or to pay an in lieu mitigation fee. For more information on heavy-duty engines, please contact Mr. Thomas Astone, Air Quality Specialist, at(559)230-5800.
