The Department of Environmental Quality will hold a public hearing on proposed amendments to ARM 17.56.101 and 17.56.402, pertaining to leak detection of USTs. The amendments would add the definition of "terminal piping" to ARM 17.56.101, amend ARM 17.56.402 to exempt terminal piping from the leak detection and tightness testing requirements, and provide an alternative technically feasible method for leak detection. The exempt piping would be leak tested annually using the procedures described in American Petroleum Institute Recommended Practices. The hearing will be held November 5, 2008. Comments are due November 6, 2008. http://deq.mt.gov/dir/legal/Notices/17-277pro.pdf.
