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