Membership Dues and Payment

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.

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.

Invoice and Payment Methods

Invoices are sent out in June for the upcoming ICAC fiscal year. Regular members with total payments of $14,000 and greater can be invoiced for either the full dues amount or elect to have the assessment portion of their payment invoiced quarterly Payment by check is preferred, with checks made payable to the Institute of Clean Air Companies. Payment may also be made using American Express, Visa, or MasterCard.
