Data Search Requests
The Montana Department of Environmental Quality, Remediation Division, Permitting and Compliance Division (Waste and Underground Tank Management Bureau), Petroleum Tank Release Compensation Board (PTRCB) and the Montana State Library, Natural Resource Information System (NRIS) are cooperatively providing database information via the NRIS Digital Atlas interactive mapper and Online Query Service. Every Monday morning at 7:00 am, current DEQ and PTRCB database information from the agencies listed above is uploaded to the NRIS data warehouse. The information is then available for use via the Digital Atlas and Online Query Service tools.
Data layers available for query, display, and reporting purposes on these sites include: Active and Inactive Regulated Underground Storage Tank sites, Abandoned/Inactive Mine sites, Active and Inactive Leaking Underground Storage Tank sites, State and Federal Superfund sites (including CERCLA, CECRA, CALA, and VCRA), other Remediation response sites (including ACGP, WQA, and Brownfields), and Petroleum Tank Release Compensation Board sites.
The Remediation Division is encouraging all interested persons to visit our website and utilize these new features for all initial conflict reviews. Interested persons can query data and print site maps utilizing the same data sets the department would use for this purpose. Maps and associated data produced from the website query tools can then be included in project planning documents as proof of site conflict search completion.
Should a person find sites in or near their area of interest, DEQ can then be contacted for more specific site information or the interested party can visit our office location to view hardcopy files. Files for the Remediation Division of the Montana DEQ are located at 1100 N. Last Chance Gulch, Helena, Montana. Libraries can be viewed during normal business hours (Monday – Friday, 8:00 am - 5:00 pm, except state holidays). Contact Jo Wallis, DEQ-Remediation Records Manager, for more information at (406) 841-5007.
DEQ photocopying and research charges are as follows: DEQ administrative support staff time is billed at $12.42 per hour. Photocopy charge is 10 cents per page. Support staff time and 10 cent per page copy charges are not billed unless they exceed $30.00. Note: Research time is charged only if it exceeds one hour. If copying/duplication/shipping is processed by outside vendor, actual vendor cost is charged per vendor invoice.

Please remember that not all sites addressed by the Department have spatial coordinates that allow them to be plotted on a map and that there are sites with coordinates that were derived by methods that may not achieve the level of accuracy desired. In addition, there may be sites, unknown to the Department that could also impact your project. Always conduct a thorough on-site inspection and contact this Department if you find evidence of a site not in our records or identify inaccuracies in our data.
A description of Remediation Division hardcopy and electronic records available for review can be found at: http://www.deq.mt.gov/rem/InformationSystems.asp. Other Divisions within the Montana DEQ maintain separate hardcopy files and electronic information systems.
