The Department of Environmental Quality amended La. Admin. Code tit. 33, pt. I, §§3905 and 3931.B, which will provide a new definition for brine from solution mining of salt from underground deposits, which was previously a subset of the definition of produced water. As the environmental hazards from brine are much lower than those of produced water, the reportable quantity will be 5,000 pounds for unauthorized discharges. http://www.doa.la.gov/osr/reg/1006/1006.pdf pp. 1241-42.
