Chapter 3 ⎯ Affected Environment3.3.10.2 Clean Air Act ConformityBecause Colorado Springs is a maintenance area for CO a conformity analysis is required. A conformitydetermination for FTC was conducted under the FTC Transformation EIS and it was determinedthat the proposed action under that EIS conformed with the applicable SIP.3.3.10.3 Existing Air Quality ConditionsAll Colorado communities are currently in attainment of all NAAQS (CDPHE 2007). ColoradoSprings once violated the federal clean air standard for CO, but developed a Carbon Monoxide MaintenancePlan for the Colorado Springs Attainment/Maintenance Area that shows how they have attainedand will maintain those standards. As a part of the redesignation, the Colorado Springs area isunder a CO Maintenance Plan until 2015 to demonstrate compliance with the Colorado NAAQS. LasAnimas County is in attainment for all the monitored criteria pollutants.3.3.10.4 Fort CarsonAir pollutant emissions are generated at FTC mainly through the combustion of fossil fuels in equipmentsuch as boilers, generators, and motorized vehicles. Combustion products include CO, nitrogenoxide (NO x ), SO 2 , PM 10 , and PM 25 . Vehicle travel on unpaved roads contributes to fugitive PM.Painting and coating activities, fuel storage, fuel operations, and chemical usage contribute to bothVOCs and hazardous air pollutants (HAPs). To a lesser extent, landfill-related emissions, militarytraining activities, and fire training activities emit VOCs and various HAPs.Prescribed burning, which supports training, ground maintenance, and the health of surrounding forestareas, is a major contributor of CO emissions. Approximately 3,000 to 10,000 acres are affectedannually by prescribed burns at Fort Carson (DECAM 2003b).Facilities with the potential to emit (PTE) more than 100 tons per year (tpy) of a criteria pollutant area part of the CDPHE’s Air Pollution Control Division (APCD)-administered Title V Operating PermitProgram. The Title V Operating Permits include listings of all air pollution regulatory requirementsapplicable to the source. The PTE represents the maximum emissions a facility could emitgiven physical, enforceable, and permitting constraints. Fort Carson is considered a Title V majorsource because of its PTE of more than 100 tpy of CO, NOx, PM, and VOCs.As a major source under the Title V program, FTC is subject to Operating Permit No. 95OPEP110.This permit was renewed on July 1, 2007. None of the current air pollutant sources has contributed toan exceedance of the NAAQS (refer to Appendix C, Air Quality Supporting Documentation in DraftFTC Transformation EIS; USACE 2007a).The Title V Operating Permit limits the use of smoke munitions and obscurant smoke for militarytraining exercises.FTC also implements FTC Regulation 200–1, promulgated in December 1999, which prescribes policiesand procedures and assigns responsibilities for the conservation, protection, and enhancement ofthe environment, including air quality, at FTC and supported facilities. The Air Quality ManagementChapter of FTC Regulation 200-1 was updated in February 2003 to provide enhanced guidance onprogram responsibilities and smoke and obscurants management. FTC Regulation 200-1 parallels AR200-1 and is specific to Fort Carson.The Fugitive Dust Control Plan (DECAM 2004a) was established as a part of the state-enforceablebest mitigation practice at Fort Carson to minimize dust impacts to air quality. It was approved by theFebruary 2008 3–176 2/25th SBCT Final EIS
