SEATTLE – The following tables summarize enforcement actions the U.S. Environmental Protection Agency’s Region 10 office completed in the second quarter of calendar year 2025. Each case is linked to the corresponding legal documents, which provide further details.

Violation: Clean Water Act

The Clean Water Act, established in 1972, is the primary federal law governing water pollution in the United States. The Clean Water Act made it unlawful to discharge any pollutant from a point source (an identifiable, localized source) into navigable waters, unless a permit is obtained. This protects human health and the environment by reducing exposure to harmful pollutants, such as those originating from raw sewage and industrial chemical discharges.

Violation: Safe Drinking Water Act

The Safe Drinking Water Act was passed by Congress in 1974 to protect human health by regulating the nation’s public drinking water supply. The act covers a variety of drinking water sources, such as rivers, lakes, reservoirs, springs, and ground water wells. The SDWA authorizes the EPA to set national health-based standards for drinking water to protect against both naturally occurring and man-made contaminants that may be found in drinking water. The reduction in a variety of contaminants in our drinking water ultimately helps to prevent a variety of health issues, ranging from gastrointestinal illnesses to even cancer.

Violation: Toxic Substances Control Act

The Toxic Substances Control Act of 1976 provides EPA with authority to require reporting, record-keeping, testing requirements, and restrictions relating to certain chemical substances. TSCA addresses the production, importation, use, and disposal of specific chemicals including polychlorinated biphenyls, asbestos, radon, and lead-based paint. This helps prevent exposure to harmful chemicals that can cause a range of health issues to humans.

Violation: Resource Conservation and Recovery Act

The Resource Conservation and Recovery Act, signed into law in 1976, gives EPA the authority to manage hazardous waste, from generation to disposal. To do this, EPA has developed the framework for states to implement safe waste management during both disasters and nonemergency times. This ultimately helps keep our economy strong, reduces human exposure to harmful contamination, and restores previously contaminated lands to be ready for productive reuse.

Violation: Federal Insecticide, Fungicide and Rodenticide Act

The Federal Insecticide, Fungicide, and Rodenticide Act gives EPA the authority to regulate the distribution, sale, production, and use of pesticides and pesticide devices in the United States. Pesticides distributed or sold in the United States must be registered (licensed) by the EPA, aside from certain exceptions. For a pesticide to be licensed, the applicant must prove that its intended use does not cause harm to the environment and does not pose a dietary risk to humans. This act helps reduce contamination in both our environment and our food, contributing to the overall well-being of the public.

It requires industry to report on the storage, use, and release of certain chemicals to federal, state, tribal, territorial and/or local governments. It also requires these reports to be used to prepare for and protect their communities from potential risks.
