The Department of Natural Resources proposed to amend Mo. Code Regs. Ann. tit.10, §26.2, Underground Storage Tanks--Technical Regulations. The changes would clarify the definition of an underground storage tank and define specific words used in the chapter. In addition, the changes would remove references to a 1998 deadline and add modern standards for testing and evaluating steel tanks. There will be a public hearing June 16, 2011, and the deadline for public comment is June 23. http://www.sos.mo.gov/adrules/moreg/current/v36n10/v36n10a.pdf pp. 1222-39.
