HB 4025 grants the Texas Railroad Commission the authority to require water pollution abatement plans for oil and gas pipelines constructed or expanded in the Edwards Aquifer recharge zone. The bill mandates that pipeline operators submit and adhere to best management practices to prevent pollution, in consultation with the Texas Commission on Environmental Quality (TCEQ). It also authorizes the Railroad Commission to impose fees for plan processing and inspections. Additionally, the bill directs the TCEQ and the Railroad Commission to create a joint consultation process and enter into a memorandum of understanding for water protection in the Edwards Aquifer region.
