This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines. SO 2 and NO x react in the atmosphere to form fine particle pollution and ground-level ozone (smog), which are linked to widespread illnesses and premature deaths. NO x emissions would drop by 52%.
