IN AUGUST 2011, THE MONTANA DEPARTMENT OF ENVIRONMENTAL QUALITY ISSUED THE RECORD OF DECISION (ROD) FOR THE BOZEMAN SOLVENT SITE. TETRACHLOROETHENE (PCE) IS THE MAIN CONTAMINANT OF CONCERN FOR THE BOZEMAN SOLVENT SITE. THE ROD IDENTIFIED THAT THE BOZEMAN SOLVENT SITE SITE-SPECIFIC CLEAN UP LEVEL (SSCL) FOR PCE IN GROUNDWATER IS 5 µg/L.THERE ARE NO BOZEMAN SOLVENT SITE GROUNDWATER MONITORING WELLS AT THE PROJECT LOCATION OR WITHIN 1000 FT. BASED ON HISTORICAL GROUNDWATER DATA, GROUNDWATER FLOW ACROSS THE BOZEMAN SOLVENT SITE IS FROM THE SOUTH TO THE NORTH AND THE DEPTH TO GROUNDWATER AT THE PROJECT LOCATION IS LIKELY AROUND 10 FEET BELOW GROUND SURFACE DEPENDING UPON TIME OF YEAR. BASED ON HISTORICAL GROUNDWATER DATA, PCE CONCENTRATIONS MAY BE PRESENT IN THE GROUNDWATER, BUT CONCENTRATIONS ARE EXPECTED TO BE LESS THAN THE SSCL OF 5 µg/L.THE ROD DOES NOT IDENTIFY CONSTRUCTION REQUIREMENTS RELATED TO THE BOZEMAN SOLVENT SITE IN THE AREA OF YOUR PROJECT. HOWEVER, IF CONSTRUCTION ACTIVITIES REQUIRE A DEWATERING PERMIT, THE CONSTRUCTION DEWATERING GENERAL PERMIT (CDGP) APPLICATION REQUIRES THE APPLICANT TO CONTACT ME (KATE FRY, MDEQ - (406) 444-6426) REGARDING CURRENT GROUNDWATER PLUME CONDITIONS. THIS EMAIL MAY SATISFY THAT REQUIREMENT. PLEASE NOTE, THE CDGP MAY HAVE DIFFERENT REQUIREMENTS FOR PCE CONCENTRATIONS THAN THE BOZEMAN SOLVENT SITE SSCL PRIOR TO DISCHARGE UNDER A CDGP. FOR ADDITIONAL INFORMATION ON THE CDGP APPLICATION PROCESS PLEASE CONTACT CHRISTINE WEAVER IN DEQ WATER QUALITY (406-444-3927 OR CWeaver@mt.gov).IN ADDITION, YOUR PROJECT IS WITHIN THE BOZEMAN SOLVENT SITE CONTROLLED GROUNDWATER AREA (CGWA). THE CGWA IS ADMINISTERED BY THE MONTANA DEPARTMENT OF NATURAL RESOURCES AND CONSERVATION (DNRC). THE CGWA LIMITS THE TYPE OF GROUNDWATER WELLS THAT CAN BE INSTALLED. PLEASE CONTACT DNRC FOR MORE INFORMATION.REV. 2/21/25
