SUBJECT: Transfer of all hard copy information to a closed PST case file
Release at DW Tower Facility, Near Bullfrog Marina at Lake Powell, Utah
Facility Identification No. 6001044, Release Site OHL

I have reviewed the file for the diesel spill at the DW Tower (DW) facility, including information obtained
by the Division of Environmental Response and Remediation (DERR). My recommendation for no further
action (NFA) at the DW release site ‘OHL’, is based on information in its case file. I recommend that no
Reporting and Remediation compliance schedule(s) be sent to the responsible party, no Leaking Petroleum
Storage Tank (LPST) file be maintained other than the UST database LUST module file, and that all
information be filed in a closed PST case file. This recommendation for closeout is based on a reported
aboveground storage tank (AST) diesel overfill event, at a remote cell-tower, near the Bullfrog Marina, Lake
Powell, Utah.

File information justifying NFA includes the following: On March 9, 2023, an Environmental Incident Report,
#16171, came to the DERR regarding a diesel spill at the DW facility. The National Parks Service, Maintenance
Supervisor, Peter Drevnick, reported that a cell tower’s emergency generator AST had a diesel spill due to an
overfill event. The spill approximated 50 gallons, and impacted an asphalt road and sandy soils. Mr. Drevnick
abated the release by excavating the visibly-impacted soils and asphalt, and placing them in a roll-off container
for proper disposal. DERR, LUST-RA and PST Compliance sections, exchanged information over several
weeks with DW’s contact, Michael Wilson; first to ensure that the spill was sufficiently abated, and second, to
determine the AST’s regulated status. By March 27, 2023, the DERR determined that the AST was not
regulated, and by April 26, 2023, the DERR was in receipt of a report from a DERR-certified PST Consultant,
providing information about abatement actions, soil disposal and soil sampling results. Submitted information
indicates the release was abated, impacted-soil was disposed of properly, and soil testing showed no petroleum
above the state-established cleanup levels. Because the diesel spill, abatement actions and the report of findings
were all associated with a non-regulated AST, NFA is recommended.
