Important information for owners and operators of field-constructed tanks (FCTs) and airport hydrant systems (AHS): You are required have a permit for your facility by July 15, 2019. You must submit your permit application by January 15, 2019 to ensure sufficient time for departmental review and approval.
List of Designated Class A/B/C Operators (rev 5/2019) and List of approved UST training providers (rev 1/2021) – 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
DOH guidance on Environmental Hazard Management Plans (EHMP) including the new Construction EHMP (C-EHMP)
for current DOH Environmental Action Levels (EALs), please refer to the EAL Surfer
September 23, 2019 – DOH SHWB and DOH UST Section have adopted the DOH HEER guidance for UST release response with this policy memo: “Use of HEER Office Environmental Action Level Guidance and HEER Office Technical Guidance Manual for Characterization and Remediation of Contaminated Properties Overseen by the SHWB“.
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. For piping runs less than 90 feet, one DU is recommended with additional DUs for additional lengths of 90 feet or less. Dispensers should have their own DUs.
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. These include: freezing of samples in collectors and extraction into methanol at the laboratory, or soil vapor (SV) site assessment. Two SV samples collected at depths of mid to bottom of the UST depth, up to 8 feet lateral from the excavation by drill rig. SV samples within the pea gravel of the UST excavation by SV probe or sampling of existing recovery wells slotted within the pea gravel may also be used. These methods are not described specifically in the DOH HEER TGM but the sample trains for sub-slab SV intrusion should be used.
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.
* 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.
