The national emission standards for hazardous air pollutants (NESHAP) for area source boilers (40 CFR part 63, subpart JJJJJJ) was published in the Federal Register on March 21, 2011 and EPA finalized changes to the rule in the Federal Register on September 14, 2016.
Some of the important changes to the rule are:

  1. An alternative particulate matter (PM) standard for new oil-fired boilers that combust only ultra-low-sulfur liquid fuel (i.e., distillate oil that has less than or equal to 15 ppm sulfur) replaced the February 2013 final rule’s alternative PM standard for new oil-fired boilers that combust low-sulfur oil
  2. A provision that requires further PM performance testing every 5 years for boilers with initial compliance tests showing that their PM emissions are equal to or less than half of the PM emission limit replaced the February 2013 final rule’s provision that eliminated further PM performance testing for such boilers.
  3. A provision that requires further fuel analysis sampling for mercury (Hg) every 12 months for coal-fired boilers with initial compliance demonstrations showing that the Hg constituents in their fuel or fuel mixture are equal to or less than half of the Hg emission limit replaced the February 2013 final rule’s provision that eliminated further fuel analysis sampling for Hg for such boilers.
