2005 Air Emissions Inventory
Criteria and Hazardous Air Pollutants Inventory Southern Ute Indian Reservation, ColoradoPresented by : Brenda Sakizzie, SUIT Senior Air Quality Specialist
Southern Ute Indian Reservation, Colorado
SUIT Air Quality
Purpose• Obtain and update baseline emissions data from various
sources within the Reservations exterior boundaries.• Last SUIT EI conducted was 2002.• The data will be used track total emissions of numerous
criteria pollutants including:– Nitric Oxides (NOx), – Carbon Monoxide (CO), – Particulate Matter (PM 10/2.5), – Sulfur Oxides (SOx),– Volatile Organic Compounds (VOC’s), and– Hazardous Air Pollutants (HAPs).
Source Categories• Point Sources:
– Title V Stationary Sources. • Area Sources:
– Oil & Gas Wells, Well-head Minor Source Compressors, Fireplace & Wood Burning Stoves, Propane Use, Airports, Gas Stations, Landfill Gas, Gravel Pits, & Agricultural.
• Mobile Sources:– On-Road Mobile Sources (paved), On-Road Mobile
Sources (unpaved), and Non-Road Mobile Sources.• Biogenic Sources
Data collection• The data collection responsibilities were divided between
the Southern Ute Indian Tribe (SUIT) Air Quality Program staff and ITEP 2006 summer intern.
• The Tribe collected data for:– all major point sources– landfills, gravel pits, gas stations, airports, mobile sources,– biogenic emissions, and other area sources.
• Utilized Tribal Emissions Inventory Software Solution (TEISS) for emissions calculations.
• Utilized BEIS Software• Utilized LandGEM software
Point Sources (Title V Sources)
Definition• Stationary sources with potential emissions of >
100 tons per year of any criteria pollutant.• Stationary source with potential to emit > 10 tons
per year of any HAP or 25 tons per year of more then one HAP
(as defined by EPA)
Point Source EmissionsPoint sources emissions on the SUIT Reservation consisting
of compressor stations and gas treatment facilities for natural gas production and distribution.

All emissions for the Title V Sources on the Reservation were taken directly from the Title V permits, Title V Permit Statement of Basis, & Title V Permit Applications.
2005 Point Source (Title V) Emissions on the SUIT Reservation (tons per year)(SOURCE: pg 12 of “SUIT 2005 EI” in Table 3.1)
Area Sources
Definition:• Stationary Sources with actual emissions between 2 and
100 tons per year of any criteria pollutant.• All other HAP emitting stationary sources that emit
between 2 and 10 tons per year of any specific HAP.– (as defined by EPA)
• Includes Oil & Gas Wells, Well-head Minor Source Compressors, Fireplace & Wood Burning Stoves, Propane use, Airports, Gas Stations, Landfill Gas, Gravel Pits and Agricultural.
Well-head & Minor Compressor Source Emissions
• Well-head & minor source compression is on the SUIT Reservation where additional compression is needed to extract natural gas from geologic formations.
• Approximately ~200 small compressor engines are located within the exterior boundaries of the Reservation (exclude Title V sources).
• Data provided by the natural gas production companies.– Emission information for each operating compressor
engine.

Mobile SourcesDefinition:• Mobile sources consist of On-road (paved), On-road
(unpaved) and non-road mobile sources. – On-road sources consist of mobile sources licensed for
use on highways or roadways.– Non-road sources consist of other mobile sources
(construction equipment, lawn/garden equipment, boats, airplanes, etc).

Biogenic
Definition:• Biogenic sources include only those pollutants that result from some sort of biological activity. • Biogenic emissions represent a significant portion
of the natural source emissions acting as ozone precursors; specifically, VOC, NOx, Isoprene, and Monoterpene.

Areas of Further Research:– Consider developing an agreement with private aircraft
owners to maintain aircraft landings/take-offs records for future SUIT EI.
– Include ammonia emissions, which EPA Region 6 is currently performing Passive Ammonia Sampling study to determine significance of ammonia emissions on Tribal lands, if any.
– Emission estimates from agricultural wind erosion and tilling operations were inconclusive. In the future, the SUIT EI should includes these emission when available on TEISS.
Future notes to keep in mind:
• Keep records of data collected for future references.• Maintain a contact list.• Submit letter of emission information requests as early as
possible– Include deadline dates and detailed spreadsheet/
questionaire of emission information to be provided.
