House Bill No. [insert bill number] aims to regulate the operation of commercial Class II saltwater disposal wells in Louisiana by enacting R.S. 30:4.4. The bill establishes a default maximum authorized surface injection pressure (MASIP) for these wells, which is calculated at 90% of the fracture gradient for the injection interval. It also creates a process for operators to apply for an increased MASIP, requiring them to demonstrate that the increase will not cause fractures through the confining zone and to provide supporting data from a licensed professional engineer or geoscientist. The Department of Conservation and Energy is mandated to approve or deny these applications within 60 days.

Additionally, the bill outlines specific criteria that operators must meet to qualify for an increased MASIP, including ensuring sufficient confining formations between the disposal well and any oil or gas wells within a one-mile radius, compliance with casing requirements, and the presence of monitoring wells for underground sources of drinking water. Violations of the permitted MASIP or any conditions set forth in the bill will be subject to penalties as established in existing law. Overall, the legislation aims to enhance the safety and regulatory framework surrounding the operation of commercial saltwater disposal wells in Louisiana.
