Water Protection Bureau

The Water Protection Bureau was formed to prevent surface and ground water pollution by review of the potential sources of pollution and issuance of Montana Pollutant Discharge Elimination System Permits. The Water Protection Bureau also is responsible for  determinations of nondegradation.

The department has compiled A GUIDE TO WATER QUALITY INFORMATION which is designed to provide access to organizational information, laws, rules, permitting information, standards, and bulletins related to water quality in Montana. It also describes the water quality related programs and activities of the DEQ.
