NESHAP JJJJJJ

If you own or operate a boiler, you may be subject to federal environmental regulations. EPA promulgated National Emission Standards for Hazardous Air Pollutants (NESHAP) JJJJJJ for industrial, commercial, and institutional boilers located at facilities that emit less than 10 tons per year of any Hazardous Air Pollutant (HAP) or less than 25 tons per year of combined HAPs. This rule does not apply to electric or gas fired boilers.
