ChemHAT, the Chemical Hazard and Alternatives Toolbox, is an internet database designed to offer up easy to use information that we can use to protect ourselves, our families and our co-workers against the harm that chemicals can cause. ChemHAT was created to answer two questions: "Can this chemical in my workplace affect my health?" and "Are there safer alternatives?" You can look up a chemical from a product or an SDS either by its chemical name or Chemical Abstracts Services (CAS) registration number.

On August 30, 2013, the U.S. Environmental Protection Agency, the Occupational Safety and Health Administration, and the Bureau of Alcohol, Tobacco, Firearms and Explosives issued a Chemical Advisory that provides information on the hazards associated with solid ammonium nitrate storage, handling and management.

Use this page to find health and safety information submitted to EPA under the Toxic Substances Control Act (TSCA). This information is intended for individuals interested in learning more about chemicals that are manufactured or imported into the United States.

The mission of the Chemical and Material Risk Management (CMRM) Program is to protect readiness, people and the environment by identifying and managing risks associated with the chemicals and materials DoD uses. They do this by enabling more effective management of current and future risks from chemicals and, in so doing, we lower lifecycle costs, drive innovation, and avoid the need for future crisis-driven retooling to comply with new regulations.

This is a free program where users can find out about the reactivity of substances or mixtures of substances.

DOE is publishing a supplemental notice of proposed rulemaking SNOPR to establish revised energy performance standards for the construction of new Federal buildings, including commercial buildings, multi-family high-rise residential buildings, and low-rise residential buildings per the ECPA, as amended by the EISA of 2007. This document presents an updated proposal with a new focus that accounts for the needs of Federal agencies and the goals of the Administration and responds to comments received on prior NOPR and SNOPR documents. Consistent with the requirements of ECPA and EISA, this document presents revised Federal building energy performance standards that would require reductions in Federal agencies' on-site use of fossil fuels (which include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils) consistent with the targets of ECPA and EISA and provides processes by which agencies can petition DOE for the downward adjustment of said targets for buildings. DOE will accept comments, data, and information regarding this SNOPR no later than 21 February 2023.

Released on 3 August 2015, the Clean Power Plan establishes the first-ever national standards to limit carbon pollution from power plants.

Growing public awareness and concern for controlling water pollution led to enactment of the Federal Water Pollution Control Act Amendments of 1972. As amended in 1977, this law became commonly known as the Clean Water Act. The Act established the basic structure for regulating discharges of pollutants into the waters of the United States. It gave EPA the authority to implement pollution control programs such as setting wastewater standards for industry. The Clean Water Act also continued requirements to set water quality standards for all contaminants in surface waters.

On July 6, 2009, the U.S. Environmental Protection Agency announced that it would develop an action plan to enhance public transparency regarding clean water enforcement performance at federal and state levels, to strengthen that performance, and to transform EPA's water quality and compliance information systems.

EPA is proposing to promulgate new methods and update the tables of approved methods for the Clean Water Act. The Clean Water Act requires the EPA to promulgate test procedures for the analysis of pollutants. Promulgating new methods and updating the tables of approved methods increases the quality and consistency of data collected for the purposes of the Clean Water Act. In this rule, the EPA proposes to add new EPA methods for per- and polyfluoroalkyl substances (PFAS) and polychlorinated biphenyl (PCB) congeners, and add methods previously published by voluntary consensus bodies that industries and municipalities would use for reporting under the EPA's National Pollutant Discharge Elimination System permit program. The EPA also proposes to withdraw the seven Aroclor (PCB mixtures) parametersComments must be received on or before 20 February 2025.

Following careful reconsideration of the water quality certification rule the EPA is finalizing a rule revising and replacing the 2020 regulatory requirements for water quality certification under CWA section 401. This final rule updates the existing regulations to better align with the statutory text and purpose of the CWA; to clarify, reinforce, and provide a measure of consistency with elements of section 401 certification practice that have evolved over the more than 50 years since EPA first promulgated water quality certification regulations; and to support an efficient and predictable certification process that is consistent with the water quality protection and cooperative federalism principles central to CWA section 401. An Executive order signed on January 20, 2021, entitled "Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis," directed the Agency to review the water quality certification rule EPA promulgated in 2020, and this final rule culminates that review. The Agency is also finalizing conforming amendments to the water quality certification regulations for EPA-issued NPDES permits. This action is effective on 27 November 2023.
