The EPA’s ACE research program and Office of Air Quality Planning and Standards (OAQPS) co-sponsored a “Wildfire Smoke Health Risk Management and Communication Workshop” with the goal to identify opportunities for research and technological solutions that could ...

The Naval Surface Warfare Center, Indian Head Division (NSWC IHD) uses a thermal method to decontaminate items that are potentially contaminated with trace amounts of energetics. These materials are termed “material potentially presenting an explosive hazard” or MPPEH. In their c...

In the U.S., fugitive emissions (leaks) of VOC and HAPs from process components have traditionally been managed using scheduled manual inspection of individual components with U.S. EPA Method 21 (M21) as part of facility LDAR programs. Although sensitive and flexible, M21 is reso...

The <i>Biofuels and the Environment: The First Triennial Report to Congress (External Review Draft)</i> (EPA/600/R-10/183A) report, prepared by the National Center for Environmental Assessment (NCEA) within EPA’s Office of Research and Development, is the first report published ...

This report updates the findings of the first Report to Congress, published in 2011, with respect to environmental and resource conservation impacts, which together are intended to address the Section 204 statutory impacts since the passage of the EISA. This report reflects the c...

EPA announced the release of the final report,<i>Biofuels and the Environment: First Triennial Report to Congress</i> (EPA/600/R-10/183F), prepared by the National Center for Environmental Assessment (NCEA) within EPA’s Office of Research and Development, as the first EPA report ...

This report characterizes the thermal performance and air pollutant emissions from a pellet-fired hydronic heater (PBHH) burning both premium hardwood and switchgrass fuels. The PBHH was operated under three load conditions: 25% (minimum); 100%; and during a simulated load profil...

The Watershed Management Optimization Support Tool (WMOST) was developed by the United States Environmental Protection Agency (US EPA) to facilitate integrated water resources management. The new Benefits Module for WMOST enables stakeholders to calculate the value of additional ...

This report “National Water Infrastructure Adaptation Assessment: Part II, Smart Urban Designer (SUD) and Case Studies” is a part of the research effort undertaken by the EPA Office of Research and Development (ORD) Water Systems Division (WSD) on national water infrastructure as...

EPA/ORD developed City-based Optimization Model for Energy Technologies (COMET) which is designed to examine energy consumption and management scenarios under various environmental policy scenarios implemented at city- and state-level. Initial application of the COMET is piloted ...

This revision of the 2011 report, Accounting Framework for Biogenic CO2 Emissions from Stationary Sources, evaluates biogenic CO2 emissions from stationary sources, including a detailed study of the scientific and technical issues associated with assessing biogenic carbon dioxide...

This study was conducted under Air, Climate and Energy (ACE) research program of EPA’s Office of Research and Development. The initial draft of the report was prepared by RTI International in Research Triangle Park, NC under U.S. EPA Contract Number EP-D-11-084, Work Assignment 4...

The maintenance of SPECIATE requires continuous assessment. EPA SWG members have established a process to identify and prioritize need, find sound research sources which address that need, critically review those sources, and finally add that data to SPECIATE. This rigorous atten...

SPECIATE is the U.S. Environmental Protection Agency&rsquo;s (EPA) repository of speciation profiles of many types of air pollution sources. The profiles provide the species makeup or composition of organic gas (such as volatile organic compounds, or VOC), particulate matter (PM...

The Global Change Assessment Model (GCAM) is an integrated assessment model that links the world's energy, agriculture and land use systems with a climate model. The model is designed to assess various climate change policies and technology strategies for the globe over long tim...

The objective of this research was to measure methane potential (Lo) in commercial and residential waste samples obtained from waste collection vehicles at the point of disposal. Previously reported Lo values span a wide range including estimates substantially lower than the cur...

Gasoline composition in the U.S. varies due to market, technical and regulatory factors. Technical factors include seasonal and elevation adjustments for drivability, and needed anti-knock properties. Regulatory factors derive from the Clean Air Act and its amendments. The Clean ...

Daily use of traditional cooking fuels and stoves in India, China, Kenya, and Ghana emits harmful air pollutants that result in over a million premature deaths annually. Reducing pollution from cookstoves is a key priority, as emissions from traditional cookstoves and open fires ...
