Pulp and Paper Noncombustion MACT Fact Sheet

June 8, 1995

DESCRIPTION: This project is to limit emissions of hazardous air pollutants (HAPs) from existing and new pulp and paper mills engaged in the production of pulp by chemically pulping wood. This part of the NESHAP pertaining to non-combustion sources (referred to as MACT I) at pulp and paper mills was coordinated into a joint proposal with the Clean Water Act (CWA) effluent guideline standards for this industry. NESHAP for chemical recovery area combustion sources (referred to as MACT II) at kraft, sulfite, and soda mills will be proposed separately (see separate fact sheet). NESHAP for nonchemical pulp and paper mills and paper machines (referred to as MACT III) will be proposed and promulgated separately.

MAIN COMPONENTS: For the pulp and paper industry, EPA is developing an integrated regulation that includes both effluent guidelines and air emission standards to control the release of pollutants to both the water and the air. The regulations are being developed jointly to provide greater protection to human health and the environment, to promote the concept of pollution prevention, and to enable the industry to more effectively plan compliance via a multimedia approach.

- Compliance timelines for CWA and CAA standards
- Definition of the MACT floor (6% vs. 12%)
- Cost of complying with the integrated rules
- Control technology bases of proposed standards
- Lack of subcategories for proposed MACT standards
- No totally chlorine-free pollution-prevention process change for papergrade kraft mills (largest sector of industry in terms of number of mills and production)
- Interaction between MACT and PSD/NSR
- Clean Fuels Exemption from RCRA for steam stripper coverheads
- Quality of data at proposal


- MACT I proposed 12/17/93
- Comments and industry data currently under review
- Issued Notice of Data Availability in FR on 2/22/95 to announce availability of industry's data
- Plan to issue 2nd FR Notice Summer '95 to announce additional data received and to take comment on changes to proposal under evaluation
- Working toward a target proposal date of late Fall '95 for MACT II (see separate fact sheet)
- Working toward a target promulgation date of late Spring '96.
- Initiating Presumptive MACT process for MACT III with Presumptive MACT identified Fall '95
STATUTORY/COURT-ORDERED DATE: Final NESHAP for all mills in source category, statutory, November 15, 1997.


- Pulp and Paper Source Category: approx. 565 mills
- MACT I: approx. 160 mills practicing chemical pulping (kraft, sulfite, semi-chemical, soda)
- MACT II: approx. 130 kraft, sulfite, and soda mills
- MACT III: < 565 mills practicing nonchemical pulping and mills with paper machines
RECOMMENDED CONTROLS: MACT I proposed MACT Floor: Enclose open process sources; route pulp mill vents to combustion device; route bleach mill vents to scrubber; route pulp mill condensates to steam stripper
