TECHNICAL SUPPORT DOCUMENT REQUIRED BY SECTION 2.2

OF APPENDIXVTO 40 CFRPART 51TECHNICAL SUPPORT DOCUMENT REQUIRED BY 40 CFRPART 51, APP . V, §2.2 (a) Identification of all regulated pollutants affected by the plan. The adopted rule establishes limits on the sulfur content offuel for use in stationary combustion installations within the State ofVermont for heat or power generation. By reducing the sulfur content offuel, sulfur dioxide, fine particulate matter, and nitrogen oxides emissions are expected to decrease. See also Vermont's Regional Haze SIP submitted to EPA on August 31, 2009 . (b) Identification of the locations of affected sources including the EPA attainment/nonattainment designation of the locations and the status of the attainment plan for the affected areas(s) . SeeVermont's Regional Haze SIP submitted to EPAon August 31, 2009 . (c) Quantification of the changes in plan allowable emissions fromthe affected sources; estimates of changes in current actual emissions fromaffected sources or, where appropriate, quantification of changes in actual emissions fromaffected sources through calculations of the differences between certain baseline levels and allowable emissions anticipated as a result of the revision. See Vermont's Regional Haze SIP submitted to EPAon August 31, 2009. (d) The State's demonstration that the national ambient air quality standards, prevention of significant deterioration increments, reasonable further progress demonstration, andvisibility, as applicable, are protected if the plan is approved and implemented

. For all requests to redesignate an area to attainment for a national primary ambient air quality standard, under section 107 of theAct, a revision must be submitted to provide for the maintenance of the national primary ambient air quality standards for at least 10 years as required by section 175Aof the Act. See Vermont's Regional Haze SIP submitted to EPA on August 31, 2009 . (e) Modeling information required to support the proposed revision, including input data, output data, models used,justification of model selections, ambient monitoring data used, meteorological data used,justification for use ofoffsite data (where used), modes of models used, assumptions, and other information relevant to the determination of adequacy of the modeling analysis. See Vermont's Regional Haze SIP submitted to EPAon August 31, 2009. (f) Evidence, where necessary, that emission limitations are based on continuous emission reduction technology.Not applicable. This submittal does not establish emission limitations but rather limits on the sulfur content offuel for use in stationary combustion installations within the State ofVermont for heat or power generation. (g) Evidence that the plan contains emission limitations, work practice standards and recordkeeping/reporting requirements, where necessary, to ensure emission levels. Not applicable - see above. (h) Compliance/enforcement strategies, including how compliance will be determined in practice. Not applicable. Vermont's procedures for determining compliance/enforcement are not changed by this submittal . (i) Special economic and technologicaljustifications required by any applicable EPA policies, or an explanation ofwhy suchjustifications are not necessary . Not applicable. There are no special economic or technologicaljustifications required.
