Operator Training 


List of approved UST training providers Jan., 11, 2019

There has been an additional vendor added to the approved operator training vendors list. The department is also working on supplemental guidance documents. Eventually these documents will be made available on our website.

Important information regarding approved operator training programs

  • Departmental approval does not equate to DOH recommendation/endorsement. Approved programs address the minimum topics required under HAR §11-280.1-242 Requirements for operator training.
  • The quality of training programs programs may vary.
  • Approved training programs may not address Hawaii-specific regulatory requirements with much detail because there is no specific requirement to do so. It is your responsibility to be in compliance with those regulations that are specific to your facility.
  • Approved training programs may not address the specific requirements that your particular facility is subject to. It is your responsibility to be in compliance with those regulations that are specific to your facility.
  • Although we do not anticipate many more revisions to this list, please check periodically to ensure that your chosen vendor has received the required approvals.

UST Release Response guidance


  1. Five decision units (DUs) are the MIS default for a UST excavation (four walls and floor).  Additional DUs are required for pipe runs and beneath dispensers.
  2. On neighbor islands, consultants may use alternative methods described in Section 5.6 of the HEER TGM to avoid the use of methanol for analyses of volatile organic compounds (VOCs) in soil samples, including freezing of samples and extraction into methanol at the laboratory.  Soil vapor samples collected at depth in the areas of UST systems may be used to assess the presence/absence of significant TPH in lieu of soil sampling for initial site assessment to avoid methanol transport by air (see Tables C-2 and E-2 in Appendix 1 of HEER EAL guidance).
  3. See Table 9-5 in DOH HEER TGM for required petroleum constituent analyses by fuel type.  Unknown USTs need TPH-g, TPH-d, TPH-o and sub-analytes on Table 9-5.*
  4. Formats for the UST Initial Release Response report and Quarterly Release Response reports may follow the format of Site Investigation reports in DOH HEER TGM 18.5.9.  Call DOH UST at (808) 586-4226 for additional information.


* For gasoline and diesel UST releases:  DOH UST and DOH HEER request that TPH-d be added to TPH-g and gasoline sub-analytes in HEER TGM Table 9-5 for gasoline releases, and that TPH-g be added to TPH-d and middle distillate sub-analytes for middle distillate (diesel, jet fuel) UST release sites.  This is for soil and groundwater analyses.  The purpose is to monitor biodegradation metabolites of petroleum that may increase or decrease in # of carbons.  [Dec 18, 2018]
