This Test and Quality Assurance Plan (TQAP) provides data quality objections for the success factors that were validated during this demonstration include energy production, emissions and emission reductions compared to alternative systems, economics, and operability, including r...

<p>This report was prepared by the Global Change Research Program (GCRP) in the National Center for Environmental Assessment (NCEA) of the Office of Research and Development (ORD) at the U.S. Environmental Protection Agency (EPA). It is intended for managers and scientists worki...

The evolution of the energy system in the United States is an important factor in future environmental outcomes including air quality and climate change. Given this, decision makers need to understand how a changing energy landscape will impact future air quality and contribute ...

The purpose of this document is to provide useful methods and guidance to support the application of sustainability indicators in EPA decision making, and particularly within the Office of Research and Development’s (ORD) research programs. The primary target audience is EPA rese...

Techniques are introduced to calculate the hourly indirect emissions benefits of three types of green power resources: wind energy, municipal solid waste (MSW) combustion, and landfill gas (LFG) combustion. These techniques are applied to each of the U.S. EPA's eGRID subregions i...

ENVIRON conducted an evaluation of the combined AERCOARE/AERMOD (AERCOARE-MOD) modeling approach for offshore sources using tracer data from four field studies. AERCOARE processes overwater meteorological data for use by the AERMOD air quality dispersion model (EPA, 2004a). AERC...

The project team applied the life cycle design methodology to the design analysis of three alternative air intake manifolds: a sand cast aluminum, brazed aluminum tubular, and nylon composite. The design analysis included a life cycle inventory analysis, environmental regulatory...

The report contains a systematic set of measurements of carbon dioxide (CO2), carbon monoxide, methane, total non-methane organic compounds, nitrous oxide, sulfur dioxide, nitrogen dioxide, and total suspended particulate emissions from the commonest combustion devices in the wor...

The report gives results of a materials flow analysis performed for composting municipal solid waste (MSW) and specific biodegradable organic components of MSW. (NOTE: This work is part of an overall U.S. EPA project providing cost, energy, and materials flow information on diffe...

The manual assists engineers in using a computer program, the ESPVI 4.0W, that models all elements of an electrostatic precipitator (ESP). The program is a product of the Electric Power Research Institute and runs in the Windows environment. Once an ESP is accurately modeled, the...

Remedial actions taken to clean up hazardous waste sites for environmental restoration and potential reuse are often sources of diesel and greenhouse gas (GHG) emissions. Many remediation systems, such as pump-and-treat (P&T), may operate for many years, demanding electricity fr...

This report provides a general overview of EPA’s national MARKAL database and energy systems model and compares various scenarios to a business as usual baseline scenario. Under baseline assumptions, total electricity use increases 1.3% annually until 2030. Annual growth in ele...

The report documents the 2002 "Selective Catalytic Reduction Mercury Field Sampling Project." An overall evaluation of the results from both 2001 and 2002 testing is also provided. The project was sponsored by the Electric Power Research Institute (EPRI), the U.S. Department of...

Clean energy provides multiple benefits. The Multiple Benefits Guide provides an overview of the environmental, energy system and economic benefits of clean energy, specifically energy efficiency, renewable energy and clean distributed generation, and why it is important to thin...

This report quantifies the energy security benefits associated with reduced oil imports due to programs and policies.

The life cycle design methodology was applied to the design analysis of three alternatives for the lower plehum of the air intake manifold for us with a 5.4L F-250 truck engine: a sand cast aluminum, a lost core molded nylon composite, and a vibration welded nylon composite. The ...

Landfill gas is produced as a result of a sequence of physical, chemical, and biological processes occurring within an anaerobic landfill. Landfill operators, energy recovery project owners, regulators, and energy users need to be able to project the volume of gas produced and re...

All federal agencies, including EPA, are required to reduce life-cycle greenhouse gas emissions attributed to facility energy use by 30% below 1990 levels by 2010. A key approach to reducing facility greenhouse gas emissions, employed by EPA, involves the purchase of "green power...

Passage of the Clean Air Act Amendments in 1990 imposed requirements on gasoline composition in the United States. Impacts to ground water are affected by the provisions that required oxygenated additives and limited benzene concentration. Reformulated and oxygenated gasoline w...

EPA has created the Environmental Technology Verification Program to facilitate the deployment of innovative or improved environmental technologies through performance verification and dissemination of information. The Air Pollution Control Technology Verification Center, a cente...

In June 1990, the U.S. Environmental Protection Agency’s Region IX Superfund Program, in cooperation with EPA’s Air and Energy Engineering Research Laboratory (AEERL), and EPA’s Superfund Innovative Technology Evaluation (SITE) Program performed a trial excavation of approximatel...

Thermophysical properties of HFE-125 (pentafluorodimethylether) suggest that it could serve as an alternative non-ozone depleting refrigerant for certain low temperature applications. This Brief presents the thermophysical properties of HFE-125 (Tables 1-4) which have been obtai...

The document is a recommended operating procedure, prepare or use in research activities conducted by EPA's Air and Energy Engineering Research Laboratory (AEERL). The procedure applies to the collection of gaseous grab samples from fossil fuel combustion sources for subsequent a...

The report gives results of an emission test of a new municipal solid waste combustor, in Biddeford, ME, that burns refuse-derived fuel and is equipped with a lime spray dryer fabric filter (SD/FF) emission control system. Control efficiency of the SD/FF emission control system ...
