North Salt Lake RefineryEPA ID UT045267127
Dear Mr. Klinghoffer,
The Division of Waste Management and Radiation Control (Division) has received the Letter Modification Request for the RFI Risk Assessment Work Plan (Request)submitted on September 11,
2024, on behalf of Big West Oil, LLC (BWO) for the refinery located at 333 West Center Street, North Salt Lake, Utah (Site).
The Request recommends that the exposure pathway for groundwater ingestion be removed from the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) Risk Assessment
(RA) Addendum Work Plan, dated July 21, 2021. The Request indicates that the exposure pathway is incomplete in that groundwater is not used for potable use, not used for irrigation,
no surface water ponds are present at the Site, and that all water used at the Site is supplied by the City of North Salt Lake. The Division agrees with the decision to remove the ingestion
of groundwater exposure pathway.
The Division has no comments or questions concerning the Request. The Request is hereby approved.
If you have any questions, please contactEthan Upton at [phone].
Sincerely,
Douglas J. Hansen, Director
Division of Waste Management and Radiation Control
