 Types of Memberships 

ICAC offers two types of membership:

  • Regular Members: Any firm, corporation, company, partnership, other business organization or entity, or any subsidiary or division thereof engaged, through sales, manufacturing or processing activities, in the design and/or supply of air pollution control systems, products, equipment, or processes.
  • Associate Members: Any contractor, supplier of equipment components, repair services or consultants to the air pollution control industry shall be eligible to apply for Associate membership. Associate Members shall not hold office or be entitled to vote except as may be specifically authorized herein.



 Membership Dues and Payment 

Membership dues are tiered based on the member companies’ projected annual air pollution control sales revenue*. Each ICAC member company is requested to self-categorize their membership dues level at the end of the prior calendar year. The dues categories are considered commitments that are then used in the aggregate to support the ICAC budget in its following fiscal year.


The ICAC fiscal year runs from July 1st through June 30th. Because self-categorization becomes a commitment, the Membership Dues Form needs to be completed by the company’s corporate or alternate ICAC representative, or an authorized person in the company. The category each member selects is confidential, with invoicing handled exclusively by ICAC headquarters staff.


For additional information on dues and applying for membership, please contact Clare Schulzki (, Executive Director, or Haley Armstrong, Director of Programs and Policy ( You may contact the ICAC office by telephone at 202-478-6188.

*Air Pollution Control Sales Revenue is defined as: "Gross receipts, less returns and allowances, from a member's air pollution control and monitoring business as would be reported on federal income tax returns (or percentage completion amount as appropriate)." Please note that "air pollution control sales revenue” as defined above includes proceeds to a U.S. or Canadian office from offshore projects booked through the U.S. or Canadian office, and business volume from all sources in air pollution control, regardless of whether these are reported as bookings. Examples of items included in "air pollution control sales revenue” in addition to air pollution control system sales are license fees, spare parts, service, and monitoring equipment revenues. Annual Projected Sales Revenue is for the 12-month period typically from January 1 through December 31 of a calendar year.
