Chemical Manufacturers Get Alternate Standards

     WASHINGTON (CN) – Chemical manufacturers will be limited to the discharge of .03 grains of particulate matter per dry standard cubic foot at the exhaust of particulate matter control devices.




     This alternative standard may be applied in place of the installation of control devices that have a 95 percent particulate matter reduction efficiency.
     The agency expects that this alternative will significantly reduce monitoring, recordkeeping and reporting requirements for small process emitters. The alternative standard does not apply to research or laboratory facilities.
