Updated Montana Underground Storage Tank rules available for comment

Friday, August 24, 2018/Categories: Department of Environmental Quality/Tags:

HELENA - The Montana Department of Environmental Quality today released proposed updated rules for underground storage tanks.


In 2015, the Environmental Protection Agency published amendments to the federal underground storage tank rules. These revisions strengthen the original underground storage tank regulations, enacted in 1988, by increasing emphasis on properly operating and maintaining UST equipment.


Montana is a primacy state in regulating underground storage tank rules, meaning DEQ is able to enact and enforce its own set of rules as long as they are no less stringent than the federal regulations. These proposed rules update Montana requirements to comply with the new federal laws. This is the first major revision since 1988.


The 2015 revised federal underground storage tank regulations added new operation and maintenance requirements, including:


  • 30-day walk-through inspections of UST facilities;
  • requiring UST system compatibility before storing certain biofuel blends;
  • removing past deferrals for field constructed tanks and airport hydrant systems;
  • updating codes of practice; and
  • making editorial and technical corrections.


The revisions will help prevent and detect UST releases, which are a leading source of groundwater contamination. They will also ensure all USTs in the United States meet the same minimum standards. 


A public hearing to accept public comments will be held September 14, 2018, at 10 a.m. at the DEQ Metcalf Building, Room 111, 1520 E. Sixth Avenue, Helena. Written comments can also be submitted to DEQWUTMBRules@mt.gov or to: Attn DEQ UST Program, 1520 E. 6th Ave. Helena, MT 59620. Comments are due by September 21, 2018, at 5 p.m.
