Administrative Rules of Montana › Department 17 - ENVIRONMENTAL QUALITY › Chapter 17.8 - AIR QUALITY › Subchapter 17.8.13 - Conformity › Rule 17.8.1310 - SPECIAL ISSUES

Current through Register Vol. 13, July 5, 2024
(1) In conducting
				consultations pursuant to ARM
				17.8.1306, responsible entities
				shall ensure that the following special issues are addressed, when applicable:
(a) evaluating and choosing a model or models
				and associated methods and assumptions to be used in hot-spot analyses and
				regional emissions analyses (see Table D, action step number 1);
(b) determining which minor arterials and
				other transportation projects should be considered "regionally significant" for
				the purposes of regional emissions analysis (in addition to those functionally
				classified as principal arterial or higher or fixed guideway systems or
				extensions that offer an alternative to regional highway travel) (see Table D,
				action step number 1), and which projects should be considered to have a
				significant change in design concept and scope from the transportation plan or
				TIP (see Table D, action step number 2);
(c) evaluating whether projects otherwise
				exempted from meeting the requirements of 40 CFR Part 93, subpart A (see
				40 CFR
				93.126 and
				93.127 ) should be treated as
				nonexempt in cases where potential adverse emissions impacts may exist for any
				reason (see Table E);
(d)
				determining, as required by 40 CFR 93.113 (c)(1), whether past
				obstacles to implementation of transportation control measures ("TCMs") that
				are behind the schedule established in the applicable implementation plan have
				been identified and are being overcome, and whether state and local agencies
				with influence over approvals or funding for TCMs are giving maximum priority
				to approval or funding for TCMs. This process shall also consider whether
				delays in TCM implementation necessitate revisions to the applicable
				implementation plan to remove TCMs or substitute TCMs or other emission
				reduction measures (see Table D, action step number 3);
(e) identifying, as required by
				40 CFR
				93.123 (b), projects located at sites in
				PM-10 nonattainment areas that have vehicle and roadway emission and dispersion
				characteristics that are essentially identical to those at sites for which
				violations have been verified by monitoring, and therefore require quantitative
				PM-10 hot-spot analysis (see Table D, action step number 1);
(f) choosing conformity tests and
				methodologies for isolated rural nonattainment and maintenance areas as
				required by 40 CFR
				93.109 (l)(2)(iii) (see Table D, action step
				number 1);
(g) determining which
				transportation plan or TIP revisions or amendments merely add or delete exempt
				projects listed in 40 CFR Part 93, subpart A (see Table E);
(h) consulting on emissions analysis for
				transportation activities which cross the borders of MPOs or nonattainment
				areas or air basins (see Table D, action step number 1);
(i) whenever the MPO does not include the
				entire nonattainment or maintenance area, determining conformity of all
				projects outside the metropolitan area and within the nonattainment or
				maintenance area (see Table D, action step number 1);
(j) designing, scheduling, and funding
				research and data collection efforts and regional transportation model
				development by the MPO or MDT (e.g., household/travel transportation surveys)
				(see Table A, action step number 1).
