A response activity by definition under Sec. 20101(1)(vv) includes the evaluation, interim response activity, remedial action, demolition, providing an alternative water supply, or the taking of other actions necessary to protect the public health, safety, or welfare, or the environment or the natural resources. Though evaluation is a response activity, additional information specific to evaluation will not be provided in this volume, but are provided in the following volumes:
- Volume 2 – Investigation Methods for the Volatilization to the Indoor Air Pathway (VIAP)
- Volume 3 – Investigation Approach for Volatilization to the Indoor Air Pathway (VIAP)
- Volume 4 – Investigative Approach for Petroleum Volatilization to the Indoor Air Pathway (VIAP)
This volume focuses specifically on interim response activities, remedial actions, and the taking of other actions necessary to protect the public health, safety, or welfare under Part 201 (typically mitigation strategies) and addresses it as three unique and separate options that include:
- Mitigation [Sec. 20101(1)(y)]
- Remedial action [Sec. 20101(1)(qq)]
- Land or resource use restriction [R 299.2(a)]
Note: The intent of this volume is as a resource to aid when a response activity has been identified through the collection and analysis of data to be warranted. While Part 201 is referenced throughout, many strategies discussed in this Volume can be applied to Part 213 sites.
