EPA NSPS Updates for Oil & Gas - Session 2

Event Description and Agenda:

On September 28, 2012, the oil and natural gas industry began reporting greenhouse gases (GHGs) for the first time through EPA's mandatory GHG reporting rule (40 CFR 98, Subpart W). Facilities must report a number of Subpart W data elements for which reporting was deferred until March 31, 2015. Reporters must submit both an expanded set of subpart W data for Reporting Year 2014 and deferred data elements for Reporting Years 2011, 2012, and 2013 as applicable.

This rulemaking requires reporting from the following industry segments: onshore petroleum and natural gas production, offshore petroleum and natural gas production, onshore natural gas processing, natural gas transmission compression, underground natural gas storage, liquefied natural gas (LNG) storage and LNG import and export.

Facilities that contain petroleum and natural gas systems that emit 25,000 metric tons or more of CO2 equivalent per year are required to report annual GHG emissions to EPA.

Additionally, on January 14, 2015, the White House released its methane "blueprint" outlining a roadmap of regulatory and voluntary initiatives that will roll out over the next two years. The blueprint will address new and modified sources in the O&G sector primarily through new regulations. EPA will propose this methane-specific regulatory standard in the summer of 2015 and finalize it in 2016, but only for new and modified sources in the sector. Other anticipated regulatory steps under the blueprint include: Control Technology Guidelines (CTG) for VOC sources, enhanced leak detection and emissions reporting, BLM regulations, PHMSA regulations, and DOE activities.

This webinar will address GHG reporting requirements in the oil and gas industry, including who must report, what information must be reported, due dates, and expanded 2015 reporting due to prior deferral. The speaker will also give information regarding the White House methane blueprint, the status of methane white papers and comments. Attendees will discuss management strategies and approaches for both GHG reporting and potential methane regulations.
