The Environmental Protection Agency (EPA) is proposing to reject revisions to the Texas State Implementation Plan (SIP) aimed at meeting the ozone standards set in 2008 for Dallas-Fort Worth (DFW) and Houston-Galveston-Brazoria (HGB) areas. These revisions, submitted by the Texas Commission on Environmental Quality between 2015 and 2020, failed to show that these areas could achieve the required air quality standards by their respective deadlines, leading to their reclassification as more severe nonattainment areas. Consequently, the EPA is proposing to disapprove the related emissions control strategies and budgets associated with these submissions. This decision aligns with federal regulations that mandate EPA action on SIP submissions that have not been withdrawn.
Simple Explanation
The EPA wants to say "no" to a plan Texas made to clean the air in two big cities, because the plan didn't show it could make the air better in time.
