The Department of Environmental Quality proposed to amend Mont. Admin. R. 17.40, pertaining to definitions, classification of systems, certification of operators, examinations, and certified operators in charge of systems. Changes are largely clarifying in nature. There will be a public hearing March 1, 2012, and the deadline for comment is March 8. See http://sos.mt.gov/arm/Register/archives/MAR2012/MAR12-03.pdf (pp. 257-64).
