Rule Summary

The pulp and paper industry consists of facilities engaged in the production of pulp and/or paper/paperboard. This category includes, but is not limited to:

  • integrated mills (where pulp and paper or paperboard are manufactured on- site),
  • non-integrated mills (where paper/paperboard or pulp are manufactured, but not both), and
  • secondary fiber mills (where waste paper is used as the primary raw material).

This subpart regulates the emissions from the pulp production sources, which include pulping process vents, bleaching process vents, and condensate streams.

Mills that chemically pulp wood using kraft, semi-chemical, sulfite, or soda processes are referred to as MACT I mills. Mills that mechanically pulp wood, or that pulp secondary fiber or non-wood fibers, or that produce paper or paperboard from purchased pulp are referred to as MACT III mills. These standards do not address emissions from recovery area combustion sources (referred to in later sections as MACT II). These sources are being regulated under a separate rule.

The National Emissions Standards for Hazardous Air Pollutants (NESHAP) for the pulp and paper production sources was originally proposed in 1993 and promulgated in 1998. In these actions, the EPA identified methanol, acetaldehyde, formaldehyde, and other hazardous air pollutants were emitted in large quantities from these sources. As a result, this subpart regulates “total HAP” emissions. In general, this regulation requires mills to do the following:

  • Collect and incinerate pulping process vent emissions
  • Collect and control bleaching process vent emissions with a caustic scrubber
  • Eliminate the use of certain bleaching chemicals
  • Collect and treat process condensate streams to remove HAPs through biological treatment or steam stripping (kraft mills only)

See the regulations in the section below for more details.
