Operator Training

List of Designated Class A/B/C Operators (rev 5/2019) and List of approved UST training providers rev. June 15, 2020 – 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, or may not address the specific requirements of your facility. It is your responsibility to be in compliance with all applicable UST regulations. Please contact DOH UST Section at 586-4226 if you have any questions on the training requirements for your facility.
  • Please check the list of training providers to ensure that your chosen vendor has received the required approvals.

UST Release Response guidance

Please follow the applicable guidance in the DOH HEER TGM, DOH HEER EAL guidance, and other guidance documents on the DOH HEER website applicable to UST release response including Multi-Increment (MI) soil sampling, monitoring well installation, Low Flow groundwater sampling, soil vapor (SV) sampling, use of appropriate EALs, and preparation of the Environmental Hazard Evaluation (EHE), and Environmental Hazard Management Plan (EHMP) for UST release response.

  • Five decision units (DUs) are requested for multi-increment soil sampling of UST excavations for USTs 6,000 gallons or larger.  For USTs less than 6,000 gallons, the four walls and floor may be combined into one DU and MIS soil sample to be sent to the lab. Additional DUs are requested for pipe runs and beneath fuel dispensers.
  • 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 in collector 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).
  • 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.*
  • 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 all groundwater analyses of gasoline UST releases, and that TPH-g be added to TPH-d and middle distillate sub-analytes for all groundwater analyses of middle distillate (diesel, jet fuel) UST release sites.  This is for groundwater analyses only.  The purpose is to monitor changes in petroleum hydrocarbon chain length as a result of bio-degradation and physical degradation in the sub-surface.  [Dec 18, 2018]
