ADA-ES TO HOST GROUNDBR EAKING CEREMONY FOR NO RTH AMERICA’S LARGEST
ACTIVATED CARBON PRODUCTION FACILITY ON OCTOBER 21 ST

LITTLETON, CO – October 13, 2008 – AD A-ES, Inc. (NASDAQ:ADE S) today announced that
on October 21 st at 11:00 AM CT, a formal groundbreaking ceremony will take place at Red River Environmental Products, LLC (RREP), in Red River Parish, LA , the construction site of what it expects will be North Am erica’s largest activated car bon (AC) production facility. Attending the event will be mem bers of ADA-ES’ senior manage ment team and its Chairman of the Board, as well as managem ent from Energy Capi tal Partners, LLC (ECP). In addition,

we have invited local and state o fficials, members of the press, and key customers who have already contracted for $160 million wort h of AC from this facility.

Earlier in the month, ADA- ES announced the formation of Crowfoot Development, LLC (Crowfoot), a joint venture wit h ECP and parent co mpany of RREP, focused on the production of AC for the mercury emissions control market for coal-fired power plants. RREP is building the AC production facility to address the pressi ng need for clean coal technologies. Coal currently powers over 50% of the electricit y generated in the country. Due to its abundance and relatively low, stable price, coal is expect ed to remain a key energy source in the U.S. However, the more than 1,100 coal -fueled power plant boilers in t he U.S. emit about 48 tons of mercury per year, or about 37% of all human-caused mercury em issions. ADA-ES’ AC has been proven to be capable of reducing mercury em issions by up to 90%. If Federal mercury control legislation is enacted or regulations are adopted, AC would represent a potential sustainable market of up to $1 billion per year.

The first production line of this facility will be capable of producing 125 to 175 million pounds of AC per year and is expected to come on-line in 2010. In addition, the air permit for the facility allows for a second production line, which, if constructed, would be capable of producing up to

an additional 175 million pounds of AC per year. Crowfoot has plans to develop additional facilities in the future, including the possibl e construction of this second production line.

The Red River Police Jury has been instrumental in supporting the locati on of the facility. Police Jury President Jesse Davis said, “The pos itive economic impact of this new facility as well as its environmentally fa vorable production make it a welcome addition to Red River

Parish. With market conditions slow and banks failing, it’s a good thin g for all new business, especially of this magnitude, to locate in our ru ral parish. It will be a boost and a big shot in thearm. All Red River Parish can say is, you ar e welcome in our community and we will work with you to make you want to stay.”

Dr. Michael Durham, President and CEO of AD A-ES, commented, “We ar e very excited to formally kick-off the construction of Crowfoot’s AC production facility. Between now and 2010, we plan to create U.S. construc tion jobs to build the $350 mil lion project, followed by 50 fulltime positions plus additional employees in mining and transportati on. We’ve enjoyed an excellent relationship with the Red River Pari sh and Louisiana state officials who had the foresight to move this project forward for the be nefit of its constituents in that it will help stimulate job creation and provid e an overall economic boost to this part of Louisiana.”
