Re: Corrective Action Plan Approval
Linde, Inc. (former Union Carbide)
Located at 12385 West U.S. Highway Alternate 40, Magna, Utah
Facility Identification No. 4002146, Release Site GAC
Dear Mr. Poole:
The Division of Environmental Response and Remediation (DERR) has completed
its review of the Corrective Action Plan (CAP) prepared by Aptim, Inc., submitted to us on
March 28, 2024, for the above-referenced facility. The CAP is in general compliance with Utah
Admin. Code R311-211 and R311-202. The DERR makes no guarantee, implied or otherwise, that
the approved CAP will successfully obtain established cleanup levels. In the event that the cleanup
goals are not met by the CAP, further work at the facility may be required prior to site closure
consideration. The public notification process has been successfully completed and there was no
substantial public interest or other reason to warrant a public meeting prior to CAP approval or
implementation of the cleanup activities. Any concerns expressed by the potentially affected public
have been resolved.
The CAP is approved and will consist of Monitored Natural Attenuation (MNA).
Additionally, the following conditions must be met: groundwater monitoring and sampling will
occur every 15 months to verify that the groundwater contamination plume is not expanding or
migrating. The first round of MNA groundwater monitoring will be in June 2025. If this schedule
has changed, please contact your project manager with an updated implementation schedule.
Any modifications to the above CAP/conditions must be reviewed and approved by the
Division Director prior to implementation.
Facility ID# 4002146

Please submit a corrective action report detailing the cleanup activities and any sample
results within 60 days after the corrective action is complete. Once it has been adequately
demonstrated that contaminant concentrations are below the established cleanup levels, you may
petition the DERR for site closure. After reviewing this information, the DERR will determine if
no further action is warranted, or if additional work is needed.

If you have any questions or concerns, please contact Liberty Coe, the DERR project
manager, at [phone].

Sincerely,

Brent H. Everett, Director
Division of Environmental Response and Remediation
