2013 Emissions Inventory
The Air Quality Bureau is conducting an emissions inventory (EI) of permitted major sources, excluding facilities in Bernalillo County and on Tribal Lands. Facilities are required to submit their emissions reports and certifications to the AQB by close of business on April 1, 2014.
The 2013 EI will be submitted through our Air Emissions Inventory Reporting (AEIR) web-based tool. This tool is only used to report actual emissions data for specific facilities in New Mexico. Data cannot be downloaded by the public through the use of this tool. Emissions inventory data can be downloaded from U.S. EPA’s National Emissions Inventory (NEI) website at http://www.epa.gov/ttn/chief/eiinformation.html. New Mexico air monitoring data can be viewed and downloaded from http://air.nmenv.state.nm.us/.
Emissions inventory data can be viewed by the public either as a downloadable csv file or on a map by going to the Title V Emissions Analysis Tool.

What is an Emissions Inventory?
The United States Environmental Protection Agency (EPA) requires states to report information regarding emissions of criteria pollutants, their precursors, and hazardous air pollutants. Emissions inventories are critical to efforts of the state, local, and federal agencies to attain and maintain the National Ambient Air Quality Standards (NAAQS) established by EPA.
Criteria pollutants include carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), lead (Pb), and particulate matter. Particulate matter includes both particulate matter 2.5 microns in diameter or less (PM2.5) and particulate matter ten microns in diameter or less (PM10). Volatile organic compounds (VOC) are precursor emissions to ozone. Precursor emissions for PM2.5 are SO2, VOC, NO2, and ammonia (NH3).
The New Mexico Environment Department (NMED) Air Quality Bureau (AQB) is required to conduct statewide emission inventories of criteria and hazardous air pollutants under 20.2.73 New Mexico Administrative Code (NMAC) Notice of Intent and Emissions Inventory Requirements.
The NMED AQB does not have jurisdiction over facilities in Bernalillo County or on Tribal lands; consequently, they are not included in the NMED AQB inventory. The NMED AQB submits the emission inventory electronically to EPA based on a schedule promulgated by EPA and contained in the Consolidated Emission Reporting Regulation (CERR). The EPA hosts states' emission inventories and compliance reports on their "Where You Live" webpage.
Types of Emission Inventory Sources
Point: large, stationary (non-mobile), identifiable source of emissions that release pollutants to the atmosphere.
Area: collectively represent point sources that have not been inventoried as a specific point, mobile, or biogenic source. They are typically sources which are too small, numerous, or difficult to inventory individually.
Mobile: motor vehicle, non-road engine, or non-road vehicle.
Motor vehicle: self propelled, used to carry people or property on a street or highway;
Non-road engine: internal combustion engine (including fuel system) that is not used in a motor vehicle, a vehicle used only for competition, or affected by sections 111 or 202 of the Clean Air Act (CAA); and
Non-road vehicle: vehicle that is run by a non-road engine and does not meet the qualities above.
4. Biogenic: all pollutants emitted from non-anthropogenic sources, for example: trees, vegetation, oil and gas seeps, and microbial activity.
Types of Information Included in an Emission Inventory
Facility name, mailing address, physical location, and contact information;
Actual emissions by pollutant including criteria pollutants, precursor pollutants, hazardous air pollutants (HAPs), and New Mexico toxic air pollutants (TAPs);
Actual operational status, hours per year, and percent throughput by quarter;
Emission unit stack parameters; and
Annual process or fuel combustion rates and fuel characteristics.
Purposes of Conducting an Emission Inventory
The NMED AQB conducts emission inventories in order to comply with state and federal regulations. The emission inventory is used to develop planning tools, conduct air dispersion modeling, and establish baseline dates used in determination of increment consumption for the Prevention of Significant Deterioration (PSD) program. It is used to measure progress in reducing emissions and to provide input for air quality management projects, such as regional haze and non-attainment areas. The emission inventory is also used to track air quality trends, provide data for the air quality report, and correlate area, industry, and source growth to pollution.
