McGregor said there were "a lot of injuries" with at least six confirmed and more expected. Authorities said that they were working to confirm exactly who was on the platform at the time of the explosion.
Coast Guard Sector New Orleans received a report from a witness at approximately 8 p.m. of an oil platform explosion.
Officials have said the fire erupted Sunday night, burning natural gas that powers some of the platform's equipment.
The site of an oil and natural gas platform explosion is called Lake Pontchartrain, but it's not a freshwater lake.
He said the four wells that feed the platform were drilled in the 1970s and are all in the lake, a brackish tidal basin that is fed both by the Gulf of Mexico and by fresh water from rivers and streams in 16 Louisiana parishes and four MS counties.
The U.S. Geological Service describes it as one of America's largest estuaries.
It is noted that the operator of the drilling platform is the company Clovelly Oil.
There are boat and helicopter crews on scene conducting the search for that person.
An explosion on an oil rig storage platform on Lake Pontchartrain in Louisiana Sunday night has left seven people injured and an eighth person missing as of Monday morning, according to local authorities.
Jefferson Parish officials say there were cleaning chemicals aboard the platform but do not know the exact cause of the fire at this time. Authorities noted that the parish drinking water is safe because it is pulled from the Mississippi River. The statement said the company's three oil wells were shut in at the time, and the flow from the gas well was cut off after the explosion.
