Sinkhole bills pass Sinkhole bills pass capitol news bureau May 29, 2013 Comments The state Senate gave final approval Tuesday night to legislation that would require prospective homeowners to be warned about nearby salt domes, mining activities or natural gas caverns. House Bill 494 was filed in response to the sinkhole crisis in Assumption Parish. The Senate voted 39-0 in favor of sending the bill to the governor’s desk. Scientists believe a company mined too close to the outer face of a dome near the Bayou Corne and Grand Bayou communities last year, causing a sidewall collapse that triggered tremors, created a 13-acre sinkhole and released gas and crude oil. The collapse occurred at a depth of more than 5,000 feet and resulted in a months-long standing mandatory evacuation of 150 residences.
