The Senate approved legislation that requires gas well operators to post signs bearing their GPS coordinates and other emergency response information at all wellsites and to share those coordinates with appropriate state, county and local officials. Emergency response plans must also be developed and shared with state, county and local officials.

Currently, firefighters, ambulance crews, and haz-mat teams may not be told where wells are being planned, or where the access roads to those sites begin. The measure requires that notification be triggered in the earliest stages of planning, rather than after waste is discharged or chemicals are brought on-site.
