Helena Sand & Gravel, Inc. Resolves DEQ Enforcement Action

Helena -- The Montana Department of Environmental Quality (DEQ) recently
settled an enforcement action with Helena Sand & Gravel, Inc. concerning
its construction activities in Helena, Montana. The enforcement action
included a $15,400 administrative civil penalty for the company's
violation of the Clean Air Act of Montana.

Larry Alheim, DEQ Environmental Enforcement Specialist, said the DEQ
took the action because the company failed to take reasonable
precautions to control dust at the I-15 exit construction site south of
Helena and at the Townsend Avenue site in Helena.

In August and October 2006, in response to several complaints, Alheim
conducted site visits at the I-15 construction site and observed excess
dust without reasonable precautions. The dust was observed extending
across both the north and south bound lanes of I-15 and extending
several hundred yards off site. On the four field visits by the DEQ
during excess dust events at the I-15 construction site, a water truck
was observed at the site but not operating.

At the Townsend Avenue site, DEQ personnel observed dust from the
company's work site impacting nearby residences and observed a lack of
reasonable precautions being taken to control the dust emissions.

Helena Sand and Gravel took corrective action to bring the sites back
into compliance, paid the fine and cooperated fully with the DEQ
throughout the enforcement action.
