Cluster Rule: This project is part of a cluster rule with the Office of Water. The Agency views clustering as an opportunity to be more efficient in rule development and to develop a rule that considers broadly the impacts on the affected industry.

  BENEFITS:
Air Emission Reduction (metric tons per year)

Reductions in emissions of the following carcinogens: chloroform, carbon tetrachloride, formaldehyde, methylene chloride, acetaldehyde, and benzene.
Reduces number of people exposed to acrolein and acetaldehyde, currently above the Rfc.
About 25 individual HAP's have been identified in pulp mill air emissions. Some other significant HAP's in addition to those listed above are methyl ethyl ketone, methanol, toluene, formaldehyde, chlorine, hydrochloric acid, and hexane.
Reducing VOC emissions (ozone precursor) would:
reduce long-term health effects (primarily lung impairments) of exposed populations.
result in improved crop yields and reduced crop damage (premature aging & leaf loss).
Reducing TRS emissions alleviates objectionable odors associated with pulp and paper production.
As a result of many months of discussions, we have reached an agreement with industry on the level of controls for the MACT standard. This control level will allow us to achieve the types of emissions reductions described above. In addition, we have identified ways to reduce the burden and costs of complying. Now, we need to finish the project to implement these standards.
