The U.S. Environmental Protection Agency (EPA) recently published revised emission factor information for fine particles less than 2.5 µm in diameter (PM2.5) for paved and unpaved roads, material transfer (conveyor transfer points) and storage piles. This information is contained in revised chapters in EPA’s AP-42 Compilation of Air Pollutant Emission Factor document (Chapters 13.2.1, 13.2.2, and 13.2.4). The revised information lowers the PM2.5 emission factors by the following amounts:
Paved roads - 40 percent
Unpaved roads - 35 percent
Material transfer points - 51 percent
Storage piles 50 - percent
These reductions will be helpful to certain industries in upcoming new source review (NSR) National Ambient Air Quality Standards (NAAQS) demonstrations for PM2.5 and development of state implementation plan (SIP) control strategies for PM2.5. For more information, refer to EPA’s Clearinghouse for Inventories and Emission Factors (CHIEF) website or contact Kent Berry at (800) 229-5299.
Most major multinational corporations believe that federal limitations on greenhouse gas emissions are coming in the next 10 years according to a recent study by the Pew Center on Global Climate Change. Many of these companies have already developed programs to voluntarily reduce greenhouse gas emissions. Companies cut emissions either by reducing emissions from their own manufacturing processes, power support facilities, and transportation fleets, or by creating more energy-efficient products to reduce consumer power demands. Energy efficiency is promoted by the Energy Star labeling program, the joint U.S. EPA-Department of Energy program designed to identify energy efficient products which help reduce greenhouse gas emissions. According U.S. EPA, greenhouse gas emissions were reduced by 63 million metric tons in 2005, 34.2 million metric tons of which can be attributed to the Energy star program. The remaining 28.8 million metric tons of emission reductions were attributed to clean energy supply programs and other programs.
Under contract with the Air Force, EQ's FOB Hope project in Iraq involves the design, renovation, and construction of a military complex for three light infantry battalions of the new Iraq Army 2nd Brigade, 6th Division. This project is scheduled to finish in March 2007 and is being completed using a local Iraqi work-force of about 400 who will expend an estimated 619,348 manhours of time to renovate or construct 44,615 square meters of buildings, structures, facilities and associated infrastructure (road network, water supply/treatment, sanitary sewer/treatment systems, power generation/distribution, lighting systems and perimeter security). In November during a ceremony at FOB Hope, EQ's in-country management team was recognized and presented with a Certificate of Appreciation by the U.S. Army MTT (Military Transition Team) for its teamwork and dedication. Let's tip our hats to the EQ Team!
