The Texas Commission on Environmental Quality fined DCP Midstream $631,628 on Wednesday.
The fines are in response to 11 different air quality violations found during an inspection at a DCP Midstream, LP site in Panola County on August 9, 2011.
DCP Midstream's fine comprises more than 50 percent of the $1,068,720 in fines that the T.C.E.Q. distributed against 36 regulated entities for violations of state environmental regulations Wednesday.
The T.C.E.Q. will give $315,814 from these fines to the Texas Railroad Commission's Alternative Fuels Clean School Bus Replacement Program to be applied toward the purchase of cleaner school buses.
