The Military Engineer l No. 66251 facilities deemed cost-effective to meter based upon the Of- ?ce of the Secretary of Defense criteria, which say that build- ings that consume an estimated $35,000 a year in electrical costs are economically justi?ed for metering. (For the Army, this equates to typical buildings that are 29,000-ft2 and larger.) The anticipated scope is a total of 13,000 advanced meters. To date, approximately 3,000 electric and natural gas meters have been installed.

This new program will cover approximately 85 percent of the nations GHG emissions and apply to roughly 10,000 facilities. This is a major step forward in our effort to address the greenhouse gases polluting our skies, said EPA Administra- tor Lisa P. Jackson. For the ?rst time, we begin collecting data from the largest facilities in this country, ones that account for approximately 85 percent of the total U.S. emissions. The American public, and industry itself, will ?nally gain critically important knowledge and with this information we can de- termine how best to reduce those emissions. EPAs new reporting system will provide a better under- standing of where GHGs are coming from and will guide development of the best possible policies and programs to reduce emissions. The data also will allow businesses to track their own emissions, compare them to similar facilities, and provide assistance in identifying cost-effective ways to re- duce emissions in the future. Greenhouse gases like carbon dioxide are produced by burning fossil fuels and through industrial and biological processes. Fossil fuel and industrial GHG suppliers, motor vehicle and engine manufacturers, and facilities that emit 25,000 metric tons or more of CO2 equivalent a year will be required to report GHG emissions data to EPA annually. This threshold is equivalent to about the annual GHG emissions from 4,600 passenger vehicles. The ?rst annual reports for the largest emitting facilities, covering calendar year 2010, will be submitted to EPA in 2011. Vehicle and engine manufacturers outside of the light-duty sector will begin phasing in GHG reporting with model year 2011. Some source categories included in the proposed rule are still under review.

Built in 1933, the 2.2-million-ft2 facility, located in midtown Manhattan, became a historic landmark in 1986. The facilitys 2.5-acre roof was constructed originally to serve as an additional mail processing location, supporting 200-lb/ft2. When the roof was scheduled for replacement in 2007, it was deemed strong enough to support the weight of the soil, vegetation and other requirements of a green roof. The green roof will last up to 50 years, twice as long as the roof it replaced. It also will reduce the amount of contaminants in stormwater runoff ?owing into New Yorks municipal water system. The agency projects the reduction of runoff to be as much as 75 percent in the summer, and up to 35 percent dur- ing the winter months. Native plants and trees used include Calamagrostis, a lush, maintenance-free grass.

The tool was devel- oped under the ESTCP project Development of a Design Tool for Planning Aqueous Amendment Injection Systems (ER- 0626). To use the tool, users enter information about the aquifer, contaminants and the concentrations of background elec- Environment & Energy News Society of American Military Engineers Cadet Dinners Honoring the Class of 2010 Support tomorrows engineering leaders, today.
