Environmental Operating Solutions Opens New Manufacturing Facilities in Portland, Oregon and Greenville, South Carolina

—Now manufacturing its MicroC™ Premium Carbon Sources at 4 US locations to serve growing demand—

BOURNE, Mass., September 22, 2008 — In response to growing demand for its MicroC™ Premium Carbon Sources, Environmental Operating Solutions, Inc. (EOSi) announced today that it had opened two new manufacturing facilities. The new facilities are located in Portland, Oregon and Greenville, South Carolina and complement the company’s existing facilities in Boston, Massachusetts and Baltimore, Maryland.

"These new production facilities expand the geography that we can economically serve with our MicroC™ Premium Carbon Sources to the Western and the Southeastern United States," said Eric Stoermer, President and Chief Executive Officer of EOSi. "We plan to continue to add new production facilities as demand grows." Nutrient removal at wastewater treatment plants is an increasingly prominent environmental issue, particularly in coastal areas where plant effluent is released into salt water resources, creating an increased market demand for MicroC™ denitrification products.

• Improved Safety: MicroCg™ is a completely nonflammable, nontoxic and 100% green product, composed entirely of renewable components.
• Quality and Consistency: MicroC™ products are manufactured to stringent quality specifications.
• Environmental Sustainability: MicroC™ products are manufactured from abundant and renewable agricultural raw materials.
• Price Stability and Cost Effectiveness: MicroC™ products have historically avoided the price fluctuations of other chemicals. They offer an economical means of reducing nitrogen load and the potential to circumvent or scale back costly nitrogen-removal upgrades to comply with increasingly stringent regulatory requirements.
• Improved Performance: MicroC™ enables faster denitrification startup and recovery periods, and improved performance in colder temperatures.
