"Antero continues to have a very bad track record of having unsafe workplace conditions resulting in too many men being severely injured," Warner said Monday.
At least five workers were hospitalized earlier this month following an explosion at an Antero natural gas well in Doddridge County.
Antero Resources owns at least 399 wells in Doddridge, Harrison, Ritchie, Tyler and Upshur counties, according to a 2012 Department of Environmental Protection database. The database lists 141 of those wells as being actively drilled; however, because the database is incomplete, that number is likely higher.
Antero has had safety problems in the past. Last August a spark at an Antero-owned well in Harrison County ignited methane gas several hundred feet underground, causing a fireball and a fire that burned for about an hour. Three workers were injured in that fire.
The DEP cited Antero for failure to maintain well control for that incident.
The DEP has cited Antero for 17 violations of state law in the past three years. Those have been primarily environmental violations -- for things like failing to prevent waste runoff, failure to report discharges and contaminating waterways.
One violation, from Jan. 4, 2013, warned, "Imminent danger water supplys threatened by allowing pollutants to escape and flow into the waters of the state."
In June 2012, Antero was drilling using water in Harrison County when they accidentally repressurized some old water wells, causing several geysers, one about 10 feet high, that flooded one nearby home and several garages.
In March 2011, state regulators shut down an Antero gas well in Harrison County after mud contaminated with drilling chemicals spilled into a nearby stream.
