Technical Guidance Manual



This is a list of the most viewed sections from the Hawaiʻi HEER TGM.

Welcome to the HEER Office Technical Guidance Manual Homepage!

The HEER Office Technical Guidance Manual (TGM), also called the Hawaiʻi HEER TGM, provides in-depth guidance on environmental assessment and cleanup under Hawaiʻi Revised Statutes, 128D.

The HEER Office TGM, accessed through the link on this homepage, has been updated and provided in an easy to use electronic format.  See "Log of TGM Updates" link for details when each section of the TGM was posted or updated for use.

The TGM contains recommended technical approaches and procedure, but is considered guidance only, not regulation. Property owners or environmental consultants can propose alternate technical strategies or methods to the HEER Office, as long as they can be demonstrated to adequately address the site investigation and/or site cleanup objectives.

Please contact the HEER Office to report releases of hazardous substances or to discuss technical questions related to reporting, release responses, or other requirements.
