HARRISBURG — A Pennsylvania government commission is giving its divided approval to regulations toughening oil and gas industry permit requirements.

The agency that reviews regulatory changes voted 3-to-2 Thursday in favor of the new regulations. The three Democratic appointees voted “yes.”

Drillers will now have to identify schools or playgrounds near wells, and if water supplies are damaged drillers will have to fix them or replace them. Natural gas drillers won’t be able to store waste in pits, or use brine to keep down dust or to de-ice.

Industry officials say the changes will add costs and could threaten businesses.
