Hazardous Materials and Waste

Hazardous materials and waste include substances that pose risks to health and the environment. These can be liquids, solids, gases, or sludges containing petroleum products, pesticides, heavy metals, and other chemicals. Managing these materials safely is essential to prevent harm during storage, transport, cleanup, and disposal.

Federal Oversight and Regulations

The Environmental Protection Agency (EPA) regulates hazardous waste under laws like the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), which guide classification, handling, and cleanup of contaminated sites. The Pipeline and Hazardous Materials Safety Administration (PHMSA) oversees safe transportation by road, rail, air, and pipeline, while OSHA sets workplace safety standards for those handling hazardous materials.

Cleanup and Remediation Efforts

When hazardous waste contaminates land or water, federal programs step in to address the damage. The EPA’s Brownfields Initiative supports cleaning up and redeveloping abandoned industrial sites. Large-scale remediation efforts tackle contaminated areas, including America’s toxic military legacy of contaminated bases, ensuring safer communities and environments.

Disposal and Transportation Guidance

Millions of tons of hazardous waste require careful management each year. To understand the broader waste disposal landscape, see where America’s waste goes. For shipping hazardous items through the mail, the U.S. Postal Service enforces strict packaging and labeling rules detailed in a guide to USPS Pub 52, protecting workers and the public during transport.
