Regional Air Quality & Airport ImpactsLarry GreeneExecutive Director/Air Pollution Control OfficerAssociation of California AirportsAnnual ConferenceSeptember 16-18, 2009

Our District MissionAchieve clean air goals by leading the region in protecting public health and the environment through innovative and effective programs, dedicated staff, community involvement and public education.

Health Effects We know Air pollution kills people Lung Disease/Toxic effects/Heart attacksAir pollution hurts the most vulnerable Asthma (children) Shortens the life of the elderlyAir pollution effects our economy Secondary effects and quality of life

Air Pollutants of ConcernOzone(ROG + NOx)

Particulates (NOx, SOx, ROG, Ammonia)

ToxicsDiesel particles, Benzene, Chromium, Asbestos

Federal/State/Local- Federal EPA - planes, trains, automobiles, large industrial sources, national standards. Federal Clean Air Act-California Air Resources Board - vehicles, fuels, consumer products, area sources, air toxic control measures. California Clean Air Act.- Local districts permit industrial sources, inspect, respond to complaints, agricultural burning, asbestos, CEQA review, public education. District rules/Board resolutions resolutions/Policies

District Background

35 Local Air AgenciesWork for local Boards of DirectorsUnique focus on local air quality and issues

Were Geographically-ChallengedSummer Ground-level Ozone (smog)

Were Geographically-ChallengedWinter Particulate Pollution Emissions + low wind + cold temperatures = High Particulate levels

Air Quality Trends - OzoneConcentrations, 1980 - 20081 hour* 35% improvement

8 hour16% improvement*2008 data adjusted for proposed exceptional events due to wildfires.

General ConformityClean Air Act - federal departments may not engage, support, fund, or approve any activity that does not conform to an approved SIP. Applies to non-attainment area pollutantsOzone (NOx, VOC), PM10 PM2.5 (under new standard) Examples:leasing of federal land,private construction on federal land,airport construction and expansions,reuse of military bases, andconstruction of federal office buildings Airport emissions inventory included in SIPs.

Master Plan Mitigation Construction Emissions Standard Construction Mitigation:Construction must meet a 20% NOx and 45% PM10 emissions reduction compared to the CARB fleet average.Exhaust cannot exceed 40% opacity for more than 3 minutes 1 hour period.Off-site mitigation fee paid for NOx emissions that exceeded 85 pounds/day threshold:Received credit for implementing Standard Construction Mitigation. ERCs used to offset a portion of the off-site mitigation fee.

Master Plan Mitigation Operational Emissions Expand use of low emission technologies when purchasing new mobile equipment andconstructing terminal facilitiesSpecific Examples in the Mitigation Monitoring and Reporting Plan:Electric charging stations for Ground Service Equipment (GSE)Gate furnished A/C and power for aircraftLow emitting buses for on-site travelSolar-energy cells for electricityHydrant fueling system to reduce fuel truck trips

Sacramento County Airport Systems Emission Reduction Credits (ERCs)Four past ERC applications: Modification to jet fueling delivery system (2005)Modernization of shuttle bus fleet (2006)Modification to air bridges to reduce the use of APUs on aircraft (2007) Electrification of some ground support equipment (2006)

Jet Fuel Delivery SystemJet fuel pipeline eliminated the need to truck jet fuel3.96 tons/year of NOx ERCs were generated for years 2006 - 2010ERCs were issued for a 10 year life per SCAS requestERCs are adjusted down over the credit life to reflect new lower state and federal emission standards for trucks:1.7 tons/year of NOx ERCs were generated for years 2011 - 2015ERCs enforced through permit conditions in the Permit to Operate for the new fueling terminalSCAS and company supplying fuel jointly hold permit ERCs have been surrendered for CEQA mitigation

Shuttle Bus ModernizationReplaced 12 diesel and 12 natural gas shuttle busesERC issued for a 10 year life per SCAS request0.5 tons/year of NOx and 0.1 tons/year of PM10 emissions credits generated (years 2007 2015)ERCs adjusted down over the credit life to reflect new lower state and federal emission standards for trucks:0.4 tons/year of NOx and 0.06 tons/year of PM10 emissions credits were generated (year 2016)0.2 tons/year of NOx and 0.03 tons/year of PM10 emissions credits were generated (year 2017)ERCs enforced by conditions in the ERC certificateERCs surrendered for CEQA mitigation

Both ERC applications were withdrawn by SCASElectrification of Air Bridges ERC application did not meet the enforceability requirementsDid not agree to require that airlines use the electrification at all timesAirlines did not want to take conditions to use electrified equipment at all timesEmission reductions from ground support equipment could not be quantified due to lack of recordsElectrification of Air Bridges&Ground Support Equipment

Estimated lead emissions are from aviation gas used for piston aircraft operations.

*If threshold to initiate monitoring is dropped to 0.5 ton/yr, 13 California airports will fall into the 0.5 ton/yr requirement. Sacramento Executive is the only airport near the 0.5 tpy threshold at 0.3 tpy according to EPAs Technical Support Document Lead Emissions from the Use of Leaded Aviation Gasoline in the US. dated October 2008, EPA420-R-08-020.

*Additional Bullets:Applied standard dust control practices Sacramento County Airport Systems banked Emission Reduction Credits (ERCs) through the District by reducing mobile source emissions at the airport in association with its jet fueling operations and shuttle bus fleet.
