The U.S. Environmental Protection Agency (EPA) has finalized revisions to the new source performance standards (NSPS) for kraft pulp mills, establishing new opacity and particulate matter emission limits; establishing additional testing, monitoring, recordkeeping, and reporting requirements; and removing the exemption for excess emissions during startup, shutdown, and malfunction.
The revisions are codified in a new NSPS subpart (40 CFR 60, Subpart BBa) which applies to kraft pulp mills that were constructed, modified, or reconstructed after May 23, 2013. The existing NSPS subpart for kraft pulp mills (40 CFR 60, Subpart BB) remains unmodified, and will continue to apply to kraft pulp mills that were constructed, modified, or reconstructed between September 24, 1976, and May 23, 2013.
EPA proposed these revisions pursuant to section 111(b)(1)(B) of the Clean Air Act, which requires EPA to review existing NSPS every eight years and revise as appropriate. The revisions became effective April 4, 2014. For additional information, contact Andrew Holway.
