Cluster Rule update

April 15th is the official release date of the Cluster Rule & Federal Register publication. The Cluster Rule became effective on June 30th, 1998. The following is a snapshot of the Final rule's impact to pulp mills:

Air: The final air rule covers MACT1 emissions (non-combustion sources from pulping and bleaching operations at chemical and semi-chemical wood pulping mills); and MACT III emissions (non-combustion sources from mills that mechanically pulp wood, pulp secondary fibers, or pulp non-wood materials, and those that use paper machine additives and solvents)*.

Cluster Rule Update - Imminent publication in the Federal Register

The EPA (Environmental Protection Agency) had sent the final and "ready-to-print" version of the Cluster Rule to the Office of Federal Register for official publication. According to reliable sources, the expected official publication date should be during the week of April 20th, 1998.

The official promulgation date of the Cluster Rule is on the same date as Federal Register publication and the rule will be effective 60 days after publication.

As requested by the Cluster Rule, the three-year and eight-year compliance periods for existing sources start at the date of promulgation (Federal Register publication). The compliance date for new sources (sources installed after the Cluster Rule Proposal on December 17th, 1993) is upon effective or startup, whichever comes later.

ENVIRONAIR has patented a new kind of
dynamic process control

U.S. Patent # 5,720,926 : Apparatus for Removing a Contaminant from a Gas

With this patent, ENVIRONAIR reveals a new way for the process control of absorption towers (scrubbing towers) in order to minimize the use of chemical reagents. In air pollution control, absorption is a well-known method for pollution control. It is usually performed with the use of a chemical active scrubbing liquid that reacts with the pollutant. For economical reasons, the use of chemical reagents should be minimized. Due to fluctuations in the concentration of pollutants, it is difficult to maintain high removal efficiency without an excess of reagents. Thus the present patent shows a new kind of dynamic process control to optimize the use of chemical reagents while maintaining high removal efficiency. The dynamic process control uses a dual loop control, which gives a faster response in time compared to the simple loop feedback control system.


December 8, 1997

ENVIRONAIR and U.S.Filter/HPD from Naperville, Illinois, have entered into an alliance that combines their respective forces.

This commercial alliance between U.S.Filter/HPD, a world leader in the Pulp and Paper industry, that designs and supplies technologies related to evaporation and stripping, and ENVIRONAIR, a process company that specializes in environmental solutions for the Pulp and Paper industry related to condensate, NCG and chlorinated gases, creates a leader in integrated environmental solutions for the pulp and paper industry.

U.S.Filter/HPD and ENVIRONAIR The agreement establishes an exclusive mutual alliance for the pulp and paper industry in North America and designates ENVIRONAIR as the exclusive representative for U.S.Filter/HPD in Québec, Ontario and Atlantic Provinces.

"Cluster Rule"

Today, the U.S. Environmental Protection Agency (EPA) has finally issued the "Cluster Rule". This action will reduce releases of toxic pollutants from pulp, paper, and paperboard mills to air and water. According to EPA Administrator, Ms. Carol Browner, it will "virtually eliminate dioxin discharges into waterways and reduce many other toxic pollutants into air and water from the nation's pulp and paper mills". EPA have created an information site ( that includes regulatory information, fact sheets, supporting documents, and technical contacts.

ENVIRONAIR will release on his website a complete summary of the "Cluster Rule" including major requirements for mills.


November 5, 1997

Cluster Rule Update - Imminent signature

Following recent informations, the Cluster Rule will be signed by Ms. Carol Browner between November 6, 1997 and Novembre 11, 1997. Full texte should be available in the EPA website within 24 hours after signature.
