automotive refinishing operations -- support 2007 attainment of the 1-hour ozone national 

ambient air quality standard. In combination with the amendment to Regulations of Connecticut 

State Agencies (R.C .S .A.) section 22a-174-38 to reduce emissions of nitrogen oxides (NOx) 

from municipal waste combustors that was approved as a SIP revision on December 11, 2001, 

these regulatory changes provide Connecticut with estimated emissions reduction benefits in 

excess of the EPA-identified shortfall of 5.4 tons per summer day for VOCs and 0.5 tons per 

summer day for NOx. See Table 1 . 

I would like to thank you and your staff for your assistance in processing this SIP revision 

toward approval. Please get in touch with me at (860) 424-3026 if the Department may provide 

any assistance.
