Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that...
AERMOD Last Updated on 2013-10-05 15:00:30AERMOD is the latest generation air dispersion model designed for short-range (up to 50 kilometers) dispersion of air pollutant emissions from stationary industrial sources. It is a steady-state plume model incorporating dispersion based on planetary boundary layer (PBL) turbulence structure and scaling, and it accomodates surface and elevated emission sources as well as simple or complex terrain.
As of December 9, 2005, the U.S. EPA designated AERMOD as the preferred model to be used for compliance with any federal and state air pollution dispersion modeling requirements. As of November 9, 2006, AERMOD completely replaces the previous preferred model known as the Industrial Source Complex (ISC) model.
The AERMOD system integrates three modules:
A steady-state Gaussian dispersion model designed for short-range dispersion of continuous emissions from stationary... More »
Leadership in Energy and Environmental Design (LEED) CertificationLast Updated on 2013-09-10 15:53:09
Leadership in Energy and Environmental Design (“LEED”) certification, which was developed and is administered by the United States Green Buildings Committee (“USGBC”), is an internationally recognized voluntary green building certification system that provides third-party verification that a building or community was designed and built using strategies aimed at improving performance. The "seal of approval" is aimed at “encourag[ing] and accelerat[ing] global adoption of sustainable green building and development practices through a suite of rating systems that recognize projects that implement strategies for better environmental and health performance.” The LEED rating system weighs and considers a building's contribution to energy savings, water efficiency, CO2 emission reduction, improvement in indoor environmental quality,...

National Center for Atmospheric ResearchLast Updated on 2013-08-21 02:53:16The National Center for Atmospheric Research (NCAR) is a non-governmental institute, based in the United States, whose stated mission is "exploring and understanding our atmosphere and its interactions with the Sun, the oceans, the biosphere, and human society."
NCAR's flagship Mesa Laboratory is located in the outskirts of Boulder, Colorado, in a dramatic complex of buildings designed by the renowned architect I. M. Pei. The site is maintained as a nature preserve.
The Mesa Laboratory includes science exhibits, an educational resource center, a library, and art galleries all of which open to the general public.
NCAR is headquartered in Boulder, Colorado, with most activity taking place on three campuses:
NCAR Mesa Laboratory: in the southwest outskirts of Boulder Foothills
Laboratory and Center Green Campus: in northeast Boulder Research
Aviation Facility: at... More »
South Coast Air Quality Management DistrictLast Updated on 2013-08-11 09:47:11The South Coast Air Quality Management District (SCAQMD), formed in 1976, is the local governmental agency in California which is responsible for regulating stationary sources of air pollution in the area depicted on the adjacent map. That area includes all of Orange county and the urban portions of Los Angeles, Riverside and San Bernardino counties. The main office of the SCAQMD is located in the city of Diamond Bar, California.
The area encompassed by the SCAQMD amounts to about 10,750 square miles (27,840 square kilometres) and is the second most populated area in the United States. This area has a severe problem with smog and the SCAQMD has been a leader in the nation's efforts to reduce air pollution emissions.
The SCAQMD develops, adopts and implements an "Air Quality Management Plan" for bringing the area into compliance with the clean air standards... More »
UK Department for Environment, Food and Rural AffairsLast Updated on 2012-04-30 00:00:00
The Department for Environment, Food and Rural Affairs (Defra) is the government department responsible for environmental protection, food production and standards, agriculture, fisheries and rural communities in the United Kingdom (UK). Formal agreements also establish the frameworks for co-operation between Defra and the Scottish Government, the Cabinet of the National Assembly for Wales and with representatives from the Northern Ireland Assembly, which have delegated responsibilities for these matters in their respective nations.
Defra also represents the UK at the European Union on agricultural, fisheries and environment matters and in other international negotiations on sustainable development and climate change, although a new Department of Energy and Climate Change was created in 2008 to take over this responsibility.
The headquarters of Defra are... More »
