Design Objectives for Emission Inventory Tool
– Develop a methodology to estimate air pollutant
emissions associated with Western underground coal
mining
– Allow estimates for historical and current operations
– Provide means to project emissions from future proposed
mining operations
– Allow emission estimates for mining operations with
limited data
How AECOM Met Study Objectives
– Developed Emission Tool using Microsoft Excel
– Estimates emissions of Criteria Pollutants, Greenhouse
Gases (GHGs), and Diesel Particulate Matter (DPM)
– Establishes standard default parameters with ability to
override
– Multiple calculation options with increasing mine-specific
data requirements for certain source categories
– Quality Assurance (QA), including listing of all default
parameters and color coding of required entries
– Complete documentation of computation methodology
and supporting data

Estimating GHG Emissions
– EPA has a well established methodology for particulate
matter emission inventory development for Western
surface mining
– Previous GHG emission inventory efforts have been site
specific or depend on monitoring data
– The methodology developed for estimating methane
emissions from underground mining is innovative
Source of Methane in a Coal Mine
– Methane is created along with
coal
– Under increasing pressure from
overburden accumulation,
methane adsorbs onto the coal
– Amount of coal absorbed
is primarily a function of
the pressure
– Upon release of pressure
during mining, the
methane desorbs from
the coal
Most Underground Mining in Colorado Involves

Methane is released from degasification wells
and ventilation exhaust
– Pre-mining degasing
– Degasing during mining
– Mine Ventilation
– Post-mining degasing
– Post-mine closure/abandonment
Methane Adsorption Curve for Western Coal
Absorption curve computed based on a pressure gradient of 0.435 pounds per square foot per foot of increasing
depth, fitted to a Michaelis-Menten distribution.

Greenhouse Gas Emission Estimation
– Emissions are a complex function of mine depth, coal
seam and coal basin characteristics, and mining methods
– Objective was to produce a simplified methodology
– Three calculation methods allowed for estimation of
desorption methane
• Coal production tonnage, seam depth, and adsorption curve
• Emission factors by state, coal basin, and drainage/degasification
system based on published EPA data, and
• Mine-specific information on methane releases
Particulate Matter Emissions from Disturbed
Areas
– EPA emission estimation requires daily maximum daily
wind speed
– Modeled a Log-Normal distribution for 3 years of data for
use in computation of daily friction velocity
(friction velocity is required in computation of wind blown dust emissions)
– Wind data included :
• Aspen
• Gunnison
• Grand Junction
Prospective Tool Uses
– Establish a consistent methodology to inventory emissions
from Western underground coal mines
– Provide input to Program Level National Environmental
Policy Act analyses
– Assess emissions for new mining lease applications
– Provide estimates of GHG emissions for climate change
and adaptation analyses
– Assess toxic risks from diesel particulate matter emissions
from underground coal mines and locomotives
Potential Area of Improvement
– Extensive information on methane emissions from
underground coal mines is being reported to EPA yearly
under 40 CFR 98 Subpart FF
– This data include methane concentrations and flow
volumes in degasification and ventilation systems
– Combined with information on mined formation, coal
basin, and mining depth, the EPA data could be
processed and incorporated into this tool
– The revised tool would allow more refined estimates of
GHG emissions for historical and future mining operations

  • 3. Design Objectives for Emission Inventory Tool – Develop a methodology to estimate air pollutant emissions associated with Western underground coal mining – Allow estimates for historical and current operations – Provide means to project emissions from future proposed mining operations – Allow emission estimates for mining operations with limited data
  • 4. How AECOM Met Study Objectives – Developed Emission Tool using Microsoft Excel – Estimates emissions of Criteria Pollutants, Greenhouse Gases (GHGs), and Diesel Particulate Matter (DPM) – Establishes standard default parameters with ability to override – Multiple calculation options with increasing mine-specific data requirements for certain source categories – Quality Assurance (QA), including listing of all default parameters and color coding of required entries – Complete documentation of computation methodology and supporting data
  • 5. Sources of Emissions Inventoried in the Tool Emission Source Pollutants Inventoried Sources Included Degasification wells Methane & CO2 Degasification well vents Mine ventilation Methane & CO2 PM10 and PM2.5 Mine ventilation system exhaust Underground equipment Criteria, GHGs & Diesel Particulate MSHA certified underground equipment and non-road vehicles Aboveground equipment Criteria, GHGs & Diesel Particulate Mobile and stationary equipment and non-road vehicles Coal Haul Locomotives Criteria, GHGs & Diesel Particulate Coal haul locomotives Aboveground material handling PM10 and PM2.5 Fugitive dust from handling and processing coal and rock Disturbed area fugitive dust PM10 and PM2.5 Windblown dust from exposed areas Paved and Unpaved Roads PM10 and PM2.5 Vehicle traffic
  • 6. Estimating GHG Emissions – EPA has a well established methodology for particulate matter emission inventory development for Western surface mining – Previous GHG emission inventory efforts have been site specific or depend on monitoring data – The methodology developed for estimating methane emissions from underground mining is innovative
  • 7. Source of Methane in a Coal Mine – Methane is created along with coal – Under increasing pressure from overburden accumulation, methane adsorbs onto the coal – Amount of coal absorbed is primarily a function of the pressure – Upon release of pressure during mining, the methane desorbs from the coal

  • 13. Mine Ventilation Rate versus Coal Production — Western Underground Coal Mines Data Sources: EPA, 2010; Colorado Department of Health, 2012
  • 14. Greenhouse Gas Emission Estimation – Emissions are a complex function of mine depth, coal seam and coal basin characteristics, and mining methods – Objective was to produce a simplified methodology – Three calculation methods allowed for estimation of desorption methane • Coal production tonnage, seam depth, and adsorption curve • Emission factors by state, coal basin, and drainage/degasification system based on published EPA data, and • Mine-specific information on methane releases
  • 15. Particulate Matter Emissions from Disturbed Areas – EPA emission estimation requires daily maximum daily wind speed – Modeled a Log-Normal distribution for 3 years of data for use in computation of daily friction velocity (friction velocity is required in computation of wind blown dust emissions) – Wind data included : • Aspen • Gunnison • Grand Junction
  • 16. Prospective Tool Uses – Establish a consistent methodology to inventory emissions from Western underground coal mines – Provide input to Program Level National Environmental Policy Act analyses – Assess emissions for new mining lease applications – Provide estimates of GHG emissions for climate change and adaptation analyses – Assess toxic risks from diesel particulate matter emissions from underground coal mines and locomotives
  • 17. Potential Area of Improvement – Extensive information on methane emissions from underground coal mines is being reported to EPA yearly under 40 CFR 98 Subpart FF – This data include methane concentrations and flow volumes in degasification and ventilation systems – Combined with information on mined formation, coal basin, and mining depth, the EPA data could be processed and incorporated into this tool – The revised tool would allow more refined estimates of GHG emissions for historical and future mining operations
