U.S. Environmental Protection Agency Method - Based on an analysis technique developed for EPA by the University of Tennessee, this method considers all major human health and enviromnental effects of the chemicals including persistence and bioaccumulation. It also includes weighting factors for the actual levels of emissions.

The United States Environmental Protection Agency has developed a criterion for determining 100% total enclosure for an industrial operation, EPA method 204 (EPA M204 2(XX)). It requires that a series of criteria be met in order for a ventilation hooded industrial process to qualify as 1(X)%... 

The Environmental Protection Agency (EPA) developed the noise-reduction rating (NRR) as a method of gauging the adequacy of a hearing protectors noise-reducing capacity. The NRR equates to the amount of decibels by which a device reduces noise exposure. When exposed to a TWA of 100 dB and the worker wears a pair of earmuffs with a NRR of 26, the calculated actual exposure would be 74 dB. 

Over a number of years, the U.S. Environmental Protection Agency has developed specialized methods for the characterization of wastes. These methods are given in the publication entitled Test Methods for Evaluating Solid Waste, ... 

To consolidate the environmental protection acth -ities of the federal government, the Environmental Protection Agency was formed on December 2, 1970 from three federal Departments, three Administrations, three Bureaus, and several other offices. The mission of EPA was to collect data on pollution, conduct research on the adverse effects of pollution, and through grants and technical assistance, develop methods for controlling it.

Based on the patch method to assess worker or re-entry exposure, researchers have developed a database, which may be used to estimate exposure. Each patch from an individual in a study can be entered into the database separately, the residue data from patches from various body areas can be summed to yield a whole-body exposure number, and the data may be sorted as to worker tasks, equipment used, protective clothing worn, formulation types and other parameters. This is the basis for the currently used Pesticide Handlers Data Base (PHED), which was developed through a joint effort in the 1980s of CropLife America [formerly known as American Crop Protection Association (ACPA) and National Agricultural Chemicals Association (NACA)], the Environmental Protection Agency (ERA) and Health Canada. " The PHED is discussed in detail in another article in this book. 

SFE instrument development has greatly been stimulated by the desire of the Environmental Protection Agency (EPA) to replace many of their traditional liquid-solvent extraction methods by SFE with carbon dioxide. In the regulatory environment, EPA and FDA approved SFE and SFC applications are now becoming available. Yet, further development requires interlaboratory validation of methods. Several reviews describe analytical SFE applied to polymer additives [89,92,324].
