The Oregon Department of Environmental Quality will hold a public meeting Tuesday evening to share information on an odor reduction agreement signed with AmeriTies-West to reduce odors in the eastern end of The Dalles.  AmeriTies manufactures railroad ties at its plant using a creosote mixture.  What the DEQ describes as an enforceable agreement contains steps the company will take to reduce odors, including best work practices, odor-control measures and enforceable milestones.  The agreement requires the company to evaluate odor-reduction actions and report back to DEQ on how successful the action was in reducing odors.  Tuesday evening’s meeting takes place at 6 p.m. in the Columbia Gorge Community College Lecture Hall in Building 2.
