TGM for the Implementation of the Hawai'i State Contingency Plan
Subsection 2.1


The process for environmental cleanup or remediation of hazardous substance releases in Hawaiʻi is guided by a set of administrative rules adopted and periodically revised by HDOH. These administrative rules, which became effective in August 1995, are referred to as the Hawaiʻi State Contingency Plan (Hawaiʻi SCP) or Hawaiʻi Administrative Rules (HAR), Title 11, Chapter 451 (HAR, 1995). The Hawaiʻi SCP was written to implement, administer, and enforce Chapter 128D of the Hawaiʻi Revised Statutes (HRS), also called the Hawaiʻi Environmental Response Law, which was established by the Hawaiʻi Legislature effective June 1991 (HRS 128D).

A hazardous substance release is defined as any spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing of any hazardous substance, pollutant, or contaminant into the environment. Note: seven specific exclusions from the definition of a release are provided in HAR 11-451-3. Sources that identify many specific hazardous substances are provided in the Hawaiʻi SCP. The Hawaiʻi SCP establishes regulatory authorities, responsibilities and guidelines for the discovery, investigation, and cleanup of hazardous substances in Hawaiʻi. Cleanup of a variety of waste, accidentally spilled substances, abandoned materials, soil, groundwater, surface water, air, and leaking underground tanks may be addressed through the Hawaiʻi SCP.

In some cases, such as during emergency responses and responses to contaminated surface water, drinking water, outdoor air, soil vapor, or leaking underground tanks, the HEER Office may refer cases to or work closely with other HDOH branches within the Environmental Health Administration (or other state, county, or federal personnel for emergency responses) to ensure appropriate assessment and cleanup is accomplished.
