The City of Manassas Sees a Clear Solution With CleanAIR

SANTA FE, NM -- (MARKET WIRE) -- April 24, 2006 -- When you see black smoke from a diesel engine billowing into the air, should you be concerned for your health? According to a recent report by the U.S. Public Interest Research Group (U.S. PIRG), fine particle pollution from diesel black smoke contributes to serious health conditions such as asthma attacks, strokes, heart attacks, and lung cancer. This could ultimately lead to the premature death of 70,000 Americans over the next 20 years, according to U.S. PIRG analysis, if levels of particle pollution are not reduced to recommended standards. Understanding this public health threat, the City of Manassas has taken action, making environmental concerns along with health a "top priority." For a solution to eliminating black smoke and reducing fine particle pollution at the city's power generation plant, Manassas turned to CleanAIR Systems, Inc.

After completing a two-year study, the Virginia Municipal Electric Association (VMEA) established a pilot program in November of 2005 to install the first of sixteen self-cleaning exhaust filter/silencer systems on their diesel electric generators located at the VMEA Generation Plant in Manassas, Virginia. CleanAIR Systems of Santa Fe, New Mexico was contracted to design and manufacture the exhaust systems. After initial testing, Energy Services Manager, Brett Massey stated, "We are exceptionally pleased with the first filter. The test results are showing about a 90 percent reduction in visible emissions." The installation of the remaining fifteen systems is scheduled for the end of April.

An integrated manufacturer of diesel emission control systems since 1993, CleanAIR Systems approaches each project as a customized design, tailored to a client's specific requirements. With the VMEA's stand-by generators, an emissions control system was needed to substantially decrease particulate matter, carbon monoxide, hydrocarbons and the odor associated with these emissions. This was achieved by installing the CleanAIR PERMIT™ Filter, a regenerating catalyzed particulate filter, verified by the California Air Resources Board (CARB) to reduce more than 85 percent of particulate matter emitted by diesel stand-by generators.

The filter traps carbon particles within a catalyzed ceramic substrate. When the engine exhaust temperature increases past a certain level, the filter self-cleans by oxidizing the particulate into harmless carbon dioxide, at the same time, decreasing other harmful gaseous emissions. "We are working towards a 0 percent opacity level by May," says Generation Supervisor, Jamie Hester. "That means no visible black smoke."

The Environmental Protection Agency has designated many metropolitan areas located in the Mid-Atlantic States, including several counties in Virginia and the District of Columbia, as having high levels of fine particle pollution, exceeding the daily national health standard. By significantly lowering particle pollution at its power generation plant, The City of Manassas, along with CleanAIR Systems, is working to change this statistic, protect the public health of the county and help create a cleaner environment for Virginia.
