Abstract

This report is submitted in fulfillment of CR 82943401 by the Research Triangle Institute (RTI) under the sponsorship of the United States Environmental Protection Agency and covers a period from September 15, 2001, to September 14, 2004. Work is continuing under a separate cooperative agreement.

The technical objective of the Environmental Technology Verification (ETV) Air Pollution Control Technologies Center (APCT Center) is to verify environmental technology performance by obtaining objective, quality-assured data, thus providing potential purchasers and permitters with an independent, credible assessment.

A stakeholders advisory committee, composed of a highly qualified core group with a wide range of perspectives and collective experience, provided guidance and input on the various factors used to evaluate candidate technologies. Candidate technologies were ranked based on several factors, including the importance of the air pollutant, commercial availability and multiple vendors, available test methods, and interest by vendors and developers.

As a priority pollutant, particulate matter was of great interest, and the APCT Center focused on technology areas that would have the most impact on reducing these emissions. Although work began during the initial pilot period, efforts continued in the verification of baghouse filtration products because of the increasing interest in high efficiency for small particle sizes. Work also continued on the verification of retrofit technologies for mobile sources and of dust suppressants, as mobile sources and fugitive dust emissions are primary sources for particulate matter. The center also continued evaluating bioreaction technologies to reduce volatile organic compound emissions.
