The changes to the USEPA Mandatory Reporting Rule (40 CFR 98) for Subpart W were finalized earlier this year.  Subpart W focuses on owners or operators of facilities that contain petroleum and natural gas systems and emit 25,000 metric tons or more of GHGs per year. The updates for Subpart W go into effect. There are additional emission sources that will have to report in Subpart W for calendar year 2025 and updates to the calculation methodology.  This webinar will review the impacts of the changes to Subpart W.  Additional measurements and monitoring will also need to be conducted starting in 2025, which will be detailed during the webinar.  The webinar will also discuss the Waste Emission Charge (WEC), which is a fee from the Inflation Reduction Act that will be imposed on methane missions for some oil and gas facilities that have to report through Subart W.
