Transcription

1 Emissions Inventory (EI) James Payne Environmental Protection Department Morongo Band of Mission Indians If needed to remind: Two-part process involving identification of potential emission sources and then calculating estimated quantities of pollutants emitted by those sources

2 Purposes of Morongo s s EI s Identify the sources impacting the quality of air on the reservation- Both internal and external Upwind and downwind Identify locations for potential monitoring Update previous EI from 1999 Provide an estimated baseline of potential emissions Analyze if quantities are increasing or decreasing Further develop capability of Tribal Air Program 2 Cover purpose, scope of area and emissions, where info came from, and what we found out.

3 Morongo Scope of Emissions Inventory 1999 &

4 Morongo Scope of Emissions Inventory 1999 & 2007 Sulfur Dioxide (SO 2 ) / SOx Nitrogen Oxides (NO & NO 2 ) / NOx Carbon Monoxide (CO) / CO Reactive Organic Gases (ROG) / VOC s Particulate Matter < 10 µm m (PM 10 Particulate Matter < ) / (PM µm m (PM 2.5 ) 10 ) 4

5 Information Gathering Existing data (from sources, air pollution control authorities, dept. of transportation, permits, other information sources) Description/location of all sources and related equipment & processes Other information needed for calculations based on AP-42 or TEISS 5

6 Information Sources MCRS Cogen - Natural gas, diesel engines, and cooling towers. Title V operating permit Part 71 operating application Engine manufacturer-includes emission control devices AP-42 6 Fuel use amount on permit. CO and PM10 emission factors from engine manufacturer and include control devices. VOC emission factor from Permit. Based on a fuel sulfur content of 1.5 gr/100 scf AP42

7 Information Sources Water Bottling Facility-Natural Gas-Fired Boilers and Dryers, Diesel Fueled Fire Pump, Cogen Facility, Cooling Towers Estimate of emissions based on pre-construction Environmental Report AP-42 Manufacturers specifications 7 Engine ratings from Iris. EF s from AP42. Used controlled emission factors b/c of FGR

8 Information Sources Diesel generators on reservation various manufacturers and engine sizes. Previous EI Manufacturer s s website AP-42 Morongo Travel Center Yearly Fuel Report South Coast Air Quality Management District 8 Use hours from previous EI. Emission factors for 5 th largest (newest) from manufacturers website, all others from ap42. MTC-Throughput from 2006 fuel report. EF s from SCAQMD

9 Information Sources Vehicle Traffic Local roads and Freeway, both on and off reservation Previous EI with 20% increase California Department of Transportation California Air Resources Board AP-42 Truck Weigh Station Communication with CHP Public Affairs Officer Previous EI CARB 9 Slide includes vehicle emissions and road release pm. Cars & motorcycles from prev. EI. Hwy traffic all vehicles from DOT. EF s from EMFAC2007. # of trucks/yr through CHP, prev EI gave idle time, EF s through EMFAC2007

10 Information Sources Railroad miles of track on/off reservation Phone Communication with Union Pacific RR EPA - Office of Air & Radiation AP-42 Airport Landings and Takeoffs Federal Aviation Administration Previous EI 10 2 sides of tracks. Phone conv-miles of track. EF s for locomotives from OAR. AP42 for sulfur. Previous EI emission factors for airport.

11 Information Sources Residential home heaters (furnaces), wood stoves, fireplaces Previous EI with 10% increase except for wood stoves AP-42 Residential Open Burning in Tons Per Year Previous EI with 90% decrease AP New home increase by 10% including fireplaces and furnaces. Trash service reduced open burning by 90%. Open burning assumed all on rez since illegal outside of it.

12 Information Sources Stationary Sources Off reservation California Emission Inventory California Air Resources Board 12 off sources were from 2005 year b/c latest available

14 Conclusions from Morongo 1999 & 2007 Inventory Trains and I-10 I traffic contribute almost all SO 2 and NO x emissions I-10 traffic contributes most of CO and ROG/VOC emissions, followed by local traffic and heating Local traffic was the primary source of PM10 and PM2.5 emissions in This effect was caused mostly by travel on unpaved roads, over 400% decrease in 2007 I-10 traffic was the primary source of PM10 in On-Reservation and Off-Reservation emissions are similar in magnitude. 14

15 Recap of Morongo EI Previous EI Used TEISS to identify new and existing sources Used consultant to quantify specific emissions from generators Data used as a comparison to evaluate sources and concerns Next step EI in 2013!!! 15
