Oil & Gas Work Group
Overview
  • The oil and gas sector is rapidly changing due to variations in commodity prices, technology innovations, and emerging regulatory programs. The Intermountain Region is especially impacted by exploration and production emissions from the oil and gas industry, and the West more broadly by emissions from the transport and use of those fuels. NAAQS exceedances during winter in production regions of Utah and Wyoming have demonstrated localized effects, while the contributions from exploration and production in the wider region on summer ozone is still being assessed. In addition, this sector must be considered for Regional Haze planning. Studies point to improvements in the emissions inventory as being one of the most needed products to improve performance of the air quality models and will be a key focus of this work group.
Responsibilities and Deliverables:
  • The Oil and Gas Work Group is:
    1. Responsible for addressing the data and analysis elements, topics, and issues under the Oil and Gas section of the WRAP Workplan (Section I.D.1)
    2. Responsible for providing oversight and coordinating efforts with projects and activities across the WRAP and with other groups related to Oil and Gas
  • The Oil and Gas Work Group will:
    1. Prepare a detailed Workplan for the TSC as inputs to update the WRAP annual Workplan for achieving these Oil and Gas analysis and planning elements. These will include:
      • Schedule for work product completion
      • Budget estimates of outside funding support needed
      • Timing of progress reports
      • Milestones to support timely and necessary Oil and Gas analysis activities
    2. Provide Work Group meeting notes and progress reports
Work Products:
  • OGWG Projected Emissions from Baseline Year Emissions Inventory – October 11, 2019
    1. The Final Report and Inventory Spreadsheet for the “Continuation of Historical Trends” projection inventory. These data will be used in modeling and control analyses for Regional Haze planning.
    2. Alternative High and Low emissions projections scenarios will be added.
  • OGWG Baseline Year Alaska and Intermountain Region Emissions Inventory revised final deliverables – Sept. 2019
    1. The Revised Final Report and Inventory Spreadsheet were completed in mid-Sept. and posted on Sept. 23, 2019. These files completely replace the previously posted July 2019 report and spreadsheet, while the gas profile information posted in July is unchanged. The July report and spreadsheet files have been removed to avoid confusion. The Revised Final Report includes updates from the July postings to include the: 1) Colorado O&G emissions based on new inventories provided by Colorado Department of Public Health and Environment and Southern Ute Indian Tribe and 2) Williston Basin casinghead gas emission inventory to correct emissions that were biased low based on EPA O&G Tool inputs.
  • OGWG Emissions Survey for State Air Agencies and O&G Operators
    1. Complete survey (January 2019)
    2. Fleet turnover and controls-focused survey (January 2019)
