Gary, NOx and particulates are pollutants mostly associated with the combustion of fuels: coal, oil and natural gas. The only place you might find them in a printing operation would be in the operation of an oxidizer (incinerator) that is burning one of these fuels. Even there the quantities being emitted would be dwarfed by the huge amounts emitted by the power industry. The name of the game in printing is VOC as an ozone generator. Of course the amount of ozone generated will also depend upon the NOx level in the atmosphere. The lower the NOx, the lower will be the amount of ozone attributable to VOC. As a consequence the EPA is trying to reduce both VOC and NOx to lower the ozone formed in the atmosphere. Right now it is a legal question. If the EPA is allowed to reduce the permitted ozone levels, as mandated in their contested 1997 regulations, you can expect more stringent controls on VOC and NOx. It is my impression that reduction of NOx is extremely difficult. I therefore expect more pressure on VOC emissions. Alexander Ross. Ph.D. Government Affairs Director RadTech International, NA 400 N.
