The EPA released the final version of the 2014 National Emissions Inventory (2014 NEIv2) in February 2018. The IWDW provides access to the emissions inventories, and resources to examine those data. Links on this page highlight efforts by the WRAP to update the base year emissions inventory and develop future year projections for key emissions sectors, such as O&G, wild fires, and major PM sources. The revised base and future year emissions will be used for WAQS photochemical modeling in the intermountain west.

EPA's 2014 NEI Dashboard
EPA's NEI website EPA website
EPA web page with 2014 NEI data summaries, data queries, and a facility mapping tool, and TSD. The 2014 NEI Dashboard displays NEI summary data trends, aggregates by source sector, process, and facility point source. A variety of maps and charts are available. The displays allow for drill down to 60 EIS emissions sectors, criteria air pollutants (CAPs), and selected hazardous air pollutants (HAPs).
A tool to display charts and maps of EPA's 2014 NEIv2. The tool is a product of a WRAP effort to review and revise the 2014 NEIv2 for photochemical modeling in the WRAP region. The full EPA NEIv2 summary dataset, including 60 emissions sectors for 20 CAPs and 282 HAPs, are accessible in the displays. The tool shows pollutant and source sector aggregates. The data supporting the tool were obtained from EPA's 2014 NEIv2 allsector data files.
2014 NEIv2
2014 NEIv2 Charting Tool
A charting and mapping tool to display emissions inventories developed by EPA and the Inventory Collaborative for the 2016 Emissions Modeling Platform (EMP). EPA platforms include 2011v6.3 (Interstate Ozone Transport) 2011 base year and 2023 and 2028 projections, and 2014 NATA base year platform. Inventory Collaborative emissions data include 2016 alpha and beta inputs.
WAQS basin level emissions inventories for oil and gas sources in the Intermountain West. The 2014 inventory data will be used for WAQS 2014 base year modeling.
For western U.S. regional analysis using photochemical modeling for Regional Haze, WESTAR-WRAP is assisting state air agencies in their review of the 2014v2 NEI. The process will allow participants to review and provide updates to these inventories. Feedback and revisions to the inventories may be incorporated into air quality modeling by the WRAP for regional photochemical modeling. The wiki contains tools and data to assist with the EI review. Point source data from EPA's 2014v2 modeling platform are available on the wiki. (See Option 2 for point source emissions files for WRAP states).
The Oil and Gas Work Group is responsible for addressing the data and analysis elements, topics, and issues contained in the Oil and Gas section of the WRAP Workplan. The Work Group recently released its Phase 1 Report which presents a road map for WRAP to develop 2014 base and future year O&G emissions projections for AQ modeling.
The Fire and Smoke Work Group assists WRAP with analysis and planning activities to support fire and smoke emissions inventories. Focus areas are scoping work to assess present and the range of future year contributions of natural sources such as fire, evaluation of Smoke Management Programs, survey and compile information about Exceptional Events assessment efforts, review the treatment of fire and smoke emissions in modeling studies, and improve coordination between state, tribal, and federal agencies.
The WRAP's Fire Emissions Tracking System (FETS) is a web-enabled database for planned and unplanned fire events. It is intended as a planning tool for daily smoke management coordination, and retrospective analyses such as emission inventories and regional haze air quality planning tasks.
