-918-<strong>The</strong> department is proposing to revise the definition of "UST system" toinclude connecting equipment including shear valves, check valves, and flexconnectors. This inclusion is necessary to implement New Rule I, which requiresunder-dispenser containment.17.56.102 APPLICABILITY (1) through (2)(b) remain the same.(3) Subchapters 2, 3, 4, 7, 8, 9, 10, <strong>13</strong>, and 14 do not apply to any of thefollowing types of PSTs and UST systems:(a) through (e) remain the same.(f) aboveground pipes associated with tanks under (3)(d) or (e), except thatpipelines regulated under the following laws are excluded:(i) the Pipeline Safety Laws (49 USC 60101, et seq.); and(ii) state law comparable to the provisions of law referred to in (3)(f)(i), if thefacility is intrastate; or(g) through (6)(c) remain the same.AUTH: 75-11-319, 75-11-505, MCAIMP: 75-11-319, 75-11-505, MCAREASON: <strong>The</strong> department is proposing to delete outdated language in ARM17.56.102(3)(f) that does not affect the meaning of the rule. <strong>The</strong> pipelinesreferenced in this subsection are excluded from regulation under the definitions inTitle 75, chapter 11, MCA, and in ARM 17.56.101. <strong>The</strong> reference to those pipelinesin this rule was intended to simply restate the exclusion in the definitions. However,the reference was inserted as an exception to a list of excluded systems, which hasthe opposite effect of what was intended. It is necessary to delete the referencebecause it is redundant and misleading.17.56.104 TANK STANDARDS FOR EXEMPTED UST SYSTEMS (1) Noperson may install an UST system listed in ARM 17.56.102(4) or (5) for the purposeof storing regulated substances unless the UST system (whether of single- ordouble-wall construction):(1) through (3) remain the same, but are renumbered (a) through (c).AUTH: 75-10-405 75-11-505, MCAIMP: 75-10-405 75-11-505, MCAREASON: <strong>The</strong> first paragraph of this rule was inadvertently not numbered ina previous rulemaking. <strong>The</strong> department is proposing to correct the rule numbering.<strong>The</strong> authorization and implementation statutes listed for ARM 17.56.104 areincorrect. Although 75-10-405, MCA, provided rulemaking authority when this rulewas adopted, the statutes were later amended and the rulemaking authority for theunderground storage tank program is now provided in 75-11-505, MCA.17.56.105 VARIANCES (1) through (6) remain the same.MAR Notice No. 17-260 <strong>13</strong>-7/5/07
