ENCLOSURE 6: 

TECHNICAL SUPPORT DOCUMENT REQUIRED BY SECTION 2 .2 

OF APPENDIX V TO 40 CFR PART 51 
TECHNICAL SUPPORT DOCUMENT REQUIRED BY 40 CFR PART 51, APP. V, §2.2 

(a) Identification of all regulated pollutants affected by the plan. 

The adopted rule establishes limits on the sulfur content of fuel for use in 

stationary combustion installations within the State of Vermont for heat or power 

generation . By reducing the sulfur content of fuel, 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). 

See Vermont's Regional Haze SIP submitted to EPA on August 31, 2009. 

(c) Quantification of the changes in plan allowable emissions from the affected 

sources ; estimates of changes in current actual emissions from affected sources or, 

where appropriate, quantification of changes in actual emissions from affected 

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 EPA on August 31, 2009. 

(d) The State's demonstration that the national ambient air quality standards, 

prevention of significant deterioration increments, reasonable further progress 

demonstration, and visibility, 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 the Act, 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 175A of 

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 of offsite 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 EPA on 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 of fuel for use in stationary combustion installations 

within the State of Vermont 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 technological justifications required by any applicable EPA 

policies, or an explanation of why such justifications are not necessary. 

Not applicable . There are no special economic or technological justifications 

required .
