The Significant New Alternatives Policy (also known as Section 612 of the Clean Air Act or SNAP, promulgated at 40 CFR part 82 Subpart G) is a program of the EPA to determine acceptable chemical substitutes, and establish which are prohibited or regulated by the EPA. [1]
The United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
ADMS-5 – See the description of this model in the alternative models section of the models accepted by the U.S. EPA. ADMS-URBAN – A model for simulating dispersion on scales ranging from a street scale to citywide or county-wide scale, handling most relevant emission sources such as traffic, industrial, commercial, and domestic sources.
EPA began issuing treatment methods and levels of requirements in 1986 and these are continually adapted to new hazardous wastes and treatment technologies. The stringent requirements it sets and its emphasis on waste minimization practices encourage businesses to plan to minimize waste generation and prioritize reuse and recycling. From the ...
Class I substances include 20 different kinds of chemicals and have all been phased-out of production processes since 2000. Class II substances consist of 33 different hydro-chlorofluorocarbons (HCFCs). The EPA has already begun plans to decrease emissions in HCFCs and plan to completely phase out the class II substances by 2030. [12]
The EPA's Science Advisory Board also pushed back against the proposal. [32] In September 2019, Wheeler signed a directive to prioritize efforts to reduce animal testing. Instead, the research should focus on new alternative test methods. The goal is to reduce its requests for, and funding of, mammal studies by 30% by 2025 and eliminate all ...
Environmental groups and the United States Environmental Protection Agency (EPA) have indicated that such alternative "wet cleaning" methods are better for the environment than perc, and proponents of wet cleaning state that these methods can be used without shrinking or otherwise damaging garments that typically require dry cleaning. [1] [2 ...
Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years. Early ideas for flue gas desulfurization were established in England around 1850. With the construction of large-scale power plants in England in the 1920s, the problems associated with large volumes of SO 2 from a single site began to ...
