What We Do

Using sound science as a compass, OCSPP’s mission is to protect you, your family, and the environment from potential risks from pesticides and toxic chemicals. Through innovative partnerships and collaboration, we also work to prevent pollution before it begins. This reduces waste, saves energy and natural resources, and leaves our homes, schools and workplaces cleaner and safer. OCSPP implements the:

  • Federal Insecticide, Fungicide, and Rodenticide Act,
  • Federal Food, Drug and Cosmetic Act,
  • Toxic Substances Control Act,
  • Pollution Prevention Act, and
  • portions of other statutes (see below).

What We Do

OPP regulates the manufacture and use of all pesticides (including insecticides, herbicides, rodenticides, disinfectants, sanitizers and more) in the United States and establishes maximum levels for pesticide residues in food, thereby safeguarding the nation's food supply. EPA has expanded public access to information about risk assessment and risk management actions to help increase transparency of decision making and facilitate consultation with the public and affected stakeholders.

In addition to our regulatory functions, we provide information and coordinate with partners and stakeholders on issues ranging from worker protection to misuse of pesticides. We participate in a variety of partnerships related to pesticide use, including the Pesticide Environmental Stewardship Program, a voluntary private and public partnership dedicated to reducing pesticide use and risk, and Integrated Pest Management in Schools.

OPP implements:

  • the Federal Insecticide, Fungicide, and Rodenticide Act
  • the Pesticide Registration Improvement Extension Act
  • and key parts of the
    • Food Quality Protection Act
    • Federal Food, Drug, and Cosmetic Act, and
    • Endangered Species Act

Learn more about our pesticides program, including general information on pesticides, how to control pests, health and safety issues (including poison prevention), environmental effects, and pesticide regulations.

What We Do

OPPT manages programs under the Toxic Substances Control Act and the Pollution Prevention Act. Under these laws, EPA evaluates new and existing chemicals and their risks, and finds ways to prevent or reduce pollution before it gets into the environment. We also manage a variety of environmental stewardship programs that encourage companies to reduce and prevent pollution. OPPT implements the Toxic Substances Control Act (TSCA), the Pollution Prevention Act and Section 313 (the Toxics Release Inventory Program) of the Emergency Planning and Community Right-to-Know Act.

Information on chemicals and their regulation under TSCA, ways to prevent and reduce pollution, and on safer chemicals and their use.
