In-situ burning (ISB) is the controlled burning of oil spilled from a vessel or pipeline. There were multiple ISB events after the Deepwater Horizon oil spill on April 20, 2010, including 410 ISBs conducted by the Coast Guard [1]. Proponents of ISB suggest that it offers a rapid ...

A fire whirl technique was tested for its ability to improve the combustion efficiency of in situ oil burns at sea. The oil burns on water tests were conducted at Texas A&M Engineering Extension Service’s (TEEX) Brayton Fire Training facility located in College Station, Texas. Em...

It is imperative to develop sampling and analytical methods to characterize FTOHs in indoor air for the development of mass transfer models to quantitatively predict FTOH emissions and transport for exposure assessment and risk management. This standard describes thermal desorpti...

The goal for this report was to examine current municipal solid waste (MSW) management infrastructure of Davenport, Iowa and provide scenarios with resilience, sustainability, and equity considerations in mind. The City of Davenport, Iowa was selected as the project site through ...

This report documents the results of an interagency project to sample emissions from in situ oil burns, comparing ground-based particulate matter measurements with measurements by aerial unmanned aircraft system (UAS). A sensor/sampler system from the Environmental Protection Age...

Thist is a summary of research conducted by the Environmental Protection Agency (EPA) )to develop a full-scale emissions test method that characterizes the application and post-application emissions from spray polyurethane foam (SPF) insulation The primary objectives of the resea...

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...

During 2013-2017, external groups published analyses suggesting that mobile source nitrogen oxide (NOx) emission estimates developed by the U.S. Environmental Protection Agency (U.S. EPA) were too high by a factor of up to two. From 2015 to 2020, a cross-EPA workgroup met to coor...

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...

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 ...

The SPECIATE Data Browser is an easy-to-use dashboard that provides access to the data in EPA's SPECIATE database through a web interface. The SPECIATE Data Browser allows you to browse information, customize charts and tables, as well as select and download the data of interest....

Over the past few years, concerns have been raised by regional environmental stakeholders regarding air quality in Maricopa County, AZ with particular attention to the presence of particulate matter and black carbon due the use of wood burning fireplaces and backyard fire pits in...

EPA Method TO-15A compiles in a single document the best practices and lessons learned by users of the method over the past 20 years. It has been totally rewritten to address and incorporate improvements in canister, sampling, preconcentration, and analytical instrumentation tec...

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 report describes the state of the science with respect to total Nr deposition budgets in the United States and the research needed to improve these budgets from both a measurement and modeling perspective. The document is intended to serve as a roadmap for research activiti...

This report covers wood stove testing carried out by ORD during May 2018 to June 2018. Testing and analysis was completed as of October 2018. Three stoves of varying design and certification level were tested using the Black Carbon Protocol developed by the International Cryosphe...

Following the collapse of the World Trade Center towers on September 11, 2001, New York State and Federal agencies initiated numerous air monitoring activities to better understand the ongoing impact of emissions from the disaster. This report focuses on these air measurement da...

Four candidate black carbon (BC) measurement techniques have been identified by the SAE International E-31 Committee for possible use in determining nonvolatile particulate matter (nvPM) mass emissions during commercial aircraft engine certification. These techniques are carbon b...

Executive Summary Environmentally responsible development of oil and gas assets requires well-developed emissions inventories and measurement techniques to verify emissions and the effectiveness of control strategies. To accurately model the oil and gas sector impacts on air qual...

Report and Appendices

The regulatory option of encouraging the adoption of advanced technologies for improving vehicle efficiency can result in significant fuel savings and GHG emissions benefits. At the same time, it is possible that some of these benefits might be offset by additional driving that i...

Background: Next generation air measurement (NGAM) technologies are enabling new regulatory and compliance approaches that will help EPA better understand and meet emerging challenges associated with fugitive and area source emissions from industrial and oil and gas sectors. In...

The effects of fine particulate matter (PM<SUB>2.5</SUB>) on human health are well documented (Pope et al., 2002). In order to spatially and temporally assess the impact of PM<SUB>2.5</SUB> on the U.S. population, the U.S. Environmental Protection Agency (U.S. EPA) operates a ne...

Exposure to formaldehyde has been shown to produce broad and potentially severe adverse human health effects. With ubiquitous formaldehyde sources in the indoor environment, formaldehyde concentrations in indoor air are usually higher than outdoors, ranging from 10 to 4000 μg/m3....
