Subject: Developmental Technologies Facility—Proposed Delisting from CECRA Priority List
Dear Mayor Mehl and Council Members:
In accordance with ARM 17.55.114(1)(b), the Montana Department of Environmental Quality (DEQ) has
published notice in the Bozeman Daily Chronicle of a 30-day public comment period on its proposal to delist
the Developmental Technologies Facility (Facility) in Bozeman, Montana, from the Comprehensive
Environmental Cleanup and Responsibility Act (CECRA) Priority List. In February 2019, the Montana
Department of Environmental Quality (DEQ) finalized a Phase U Environmental Site Assessment (ESA) of
the Facility. The ESA identified one contaminant of potential concern, benzo(a)pyrene, which exceeded the
Montana Tier 1 Risk-Based Corrective Action (RBCA) Guidance for Petroleum Releases residential direct
contact risk-based screening level. However,the one soil sample did not exceed the RBCA Tier 2
residential screening levels.No samples exceeded any other generic screening levels in surface,subsurface,or
groundwater samples. Therefore,DEQ determined it was appropriate to initiate the delisting procedure under
ARM 17.55.114(1)(b)to remove the above-referenced Facility from the CECRA Priority List. As provided
for in ARM 17.55.114(6)(c), DEQ is notifying you as well as the Gallatin County Commissioners and the
Gallatin County Health Department.
The public comment period on this proposed delisting will begin on June 5,2020,and written comments must
be received in the DEQ office by midnight on July 5,2020. Copies of site-related documents are available at
the DEQ Waste Management and Remediation office located at 1225 Cedar St. in Helena. DEQ will hold a
public meeting upon written request to DEQ on or before June 5,2020, by 10 or more persons, a group of 10
or more persons,or by a local governing body of a city,town,or county. Written comments may be submitted
to Jason Seyler at DEQ-Remediation Division, P.O. Box 200901, Helena, MT 59620 or via email at
jseyler@mt.gov. Comments received through the postal service must be postmarked no later than July 5,2020, "
