Subpart W - General
- Q439. How does this final rule relate to EPA's Natural Gas STAR program?
- Q441. When registering my subpart W facility in e-GGRT, how should I enter the facility address?
- Q444. How is a facility defined and who must report under subpart W (petroleum and natural gas systems )?
- Q446. How are greenhouse gas emissions calculated for subpart W (petroleum and natural gas systems) facilities?
- Q447. What information must be reported by subpart W (petroleum and natural gas systems) facilities?
- Q460. Will EPA provide a tool to assist oil and natural gas system facilities in assessing their applicability under this rule?
- Q461. When does reporting for subpart W begin?
- Q462. Does the final rule amending 40 CFR Part 98 apply to both onshore and offshore petroleum and natural gas production?
- Q614. The applicability tool for Onshore Petroleum and Natural Gas has an operating factor for associated gas venting from produced hydrocarbons. How does this operating factor correlate with the barrels of crude oil produced?
- Q615. With the "Liquefied Natural Gas Storage" option selected in the Applicability Tool, how does the "calculation utility" excel spreadsheet account for "Population Count and Emission Factors" when providing the user with a final CO2e number?
- Q616. Where can I find the screening tool for onshore petroleum and natural gas production?
- Q617. Does EPA offer guidance on estimating a worst case scenario for emissions from transmission storage tanks (i.e., onshore transmission compression and underground storage facilities, beginning in RY 2025) for the purpose of determining applicability?
- Q618. For estimating compressor rod-packing venting, the Transmission Compression Tool units are "number of compressor cylinders" while the Underground NG Storage Tool units are "number of compressors". What is the difference and which should be used?
- Q619. 40 CFR 98.237 specifies that a monitoring plan required by 40 CFR 98.3(g)(5) must be completed by April 1, 2011. For a facility that became subject to reporting after April 1, 2011, when does a GHG monitoring plan have to be in place?
- Q622. Do the emissions from external combustion sources with rated heat capacity equal to or less than 5 mmBtu per hour need to be included in the 25,000 metric ton threshold determination?
- Q623. My question concerns the calculation of standard temperature and pressure. The rule stipulates what standard temperature and pressure are, but how, for an annual average, is actual temperature and pressure defined?
- Q624. Should self-propelled workover equipment be included for reporting GHG emissions under Subpart W?
- Q667. How do I determine applicability for Subpart W facilities with stationary combustion sources?
- Q731. What segments of the petroleum and natural gas systems sector are covered by the current GHGRP data?
- Q732. Does the current GHGRP data include all U.S. emissions from petroleum and natural gas systems?
- Q733. What percentage of emissions from petroleum and natural gas systems are reported under the GHGRP?
- Q736. Do all petroleum and natural gas system facilities subject to the Greenhouse Gas Reporting Program report to EPA?
- Q737. What is the quality of the petroleum and natural gas systems data?
- Q749. What are the notification requirements when an Onshore Petroleum and Natural Gas Production facility, reporting under Subpart W, sells wells and associated equipment in a basin?
- Q765. How do I determine “actual” temperature and pressure in emission calculations?
- Q766. What are the requirements for determining the GHG mole fraction for emission calculations when a continuous gas composition analyzer is not available?
- Q767. What are the requirements for determining the volume of gas sent to a flare?
- Q859. Are visual inspections still required for thief hatches if a visual inspection is unsafe to perform due to the contents of the storage tank?
- Q860. Can EPA clarify which liquid throughput quantities in 40 CFR 98.236(aa) are required to be measured via flow meters?
- Q861. How are owners/operators expected to review facility data for the purposes of identifying Other Large Release Events?
