VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: Rule 400. 4 Emissio ns of Oxides of Nitrogen from Wallboard Kilns strengthens the Air Districts commitment to

the application of Reasonable Available Control Technology (RACT) and is the accomplishment of a commitment to RACT

made during the RACM/RACT submittal to US EPA back in 2009.
