How do certified third-party notifiers figure out the owner(s)/operator(s) to include in submitted notifications? Will EPA review these attributions before making them publicly available?

When entities apply to become certified third-party notifiers, among other things, they must provide EPA information about their standard operating procedures. This includes their process for identifying and verifying the owner/operator of a site where a super-emitter event occurs and the source of information that will be used to make the identification. When a certified third-party notifier submits a notification to EPA, it must include information on owners/operators of any oil and natural gas facility (e.g., individual well site, centralized production facility, natural gas processing plant, or compressor station) within 50 meters of the latitude and longitude coordinates of the super-emitter event, if available. EPA anticipates that third parties will use commercial and publicly available sources, such as state databases, to identify the owners and operators of these facilities. EPA is providing certified third-party notifiers with training on how existing data sources can be used for these purposes. EPA will post owner/operator attributions that have been confirmed through the responses received; where response submittal deadlines have passed but no responses have been received, the EPA intends to post owner/operator attributions that the EPA reasonably believes to be accurate.
