Why Was HAZWOPER Created? (Past Incidents That Lead to This)

Why Was HAZWOPER Created

HAZWOPER, which stands for Hazardous Waste Operations and Emergency Response, was created primarily to protect workers who are involved in five specific types of operations conducted at hazardous waste sites. These operations include:

  1. Clean-up operations involving hazardous substances that are conducted at uncontrolled hazardous waste sites (such as, but not limited to, the EPA’s National Priority List sites, state priority site lists, sites recommended for the EPA’s National Priority List, and initial investigations of government-identified sites that are conducted before the presence or absence of hazardous substances has been ascertained).
  2. Corrective actions involving clean-up operations at sites covered by the Resource Conservation and Recovery Act (RCRA).
  3. Voluntary clean-up operations at sites recognized by federal, state, local, or other governmental bodies as uncontrolled hazardous waste sites.
  4. Operations involving hazardous wastes that are conducted at treatment, storage, and disposal facilities regulated by Title 40 Code of Federal Regulations Parts 264 and 265 pursuant to RCRA, or by agencies under agreement with U.S. Environmental Protection Agency to implement RCRA regulations.
  5. Emergency response operations for releases of, or substantial threats of releases of, hazardous substances regardless of the location of the hazard.

The Occupational Safety and Health Administration (OSHA) developed standards in response to the U.S. Congress passing the Superfund Amendments and Reauthorization Act (SARA) of 1986. This act emphasized the importance of a well-trained workforce in reducing risks associated with hazardous waste operations and emergency services.

The aim is to ensure that workers involved in these operations have the necessary training, knowledge, and resources to safely handle hazardous substances and to mitigate or prevent incidents that could harm public health or the environment.
