Welcome to the HEER Office Technical Guidance Manual Homepage!

The HEER Office Technical Guidance Manual (TGM), also called the Hawai'i HEER TGM, provides in-depth guidance on environmental assessment and cleanup under Hawai'i 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 use this TGM homepage to Register for TGM Update Announcements, or to Submit Comments to the HEER Office on TGM corrections, suggested edits, or the need for additional guidance. Input received will be carefully considered for periodic updates or additions to the TGM.

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