RE: Notification Letter for Monitoring Well and Piezometer Abandonment at
Multiple Solid Waste Management Units (SWMUs) Across the Site – Former
Geneva Steel Facility, Vineyard, Utah

Dear Mr. Hansen:
On behalf of United States Steel Corporation (USS) and Anderson Geneva, LLC
(Geneva), this letter is to notify the Utah Department of Environmental Quality (UDEQ)
of monitoring well, piezometer, and recovery well abandonment at the former Geneva
Steel facility (Site) in Vineyard, Utah

Background
USS and Geneva have identified monitoring wells, piezometers, and recovery wells at
Solid Waste Management Units (SWMUs) that have been closed, both Corrective Action
Complete Without Controls (CACWOC) and Corrective Action Complete With Controls
(CACWC), and are no longer needed at the Site. See Table 1 for a list of wells and
rationale for abandonment. Therefore, to support development activities, USS and
Geneva intend to perform the abandonment activities identified below.

Specific Planned Activities
The specific planned activities are:
 Abandon 15 monitoring wells and 9 piezometers that are no longer needed for
project purposes at the Site (Table 1, Figure 1).
 Abandon 8 recovery wells located at the GW-4.10 South Quench Tower Sump
area (identified with the letters RW in the list below) that are no longer required
(Table 1, Figure 1).

Procedures
Well abandonment and documentation will be performed in general accordance with
procedures set forth in Utah Administrative Code R655-4-14. The depths of all wells
proposed for abandonment are less than 30 feet below ground surface and, in accordance

Page 2 of 3
with Utah Administrative Code R655-4-14, will not require submittal of an abandonment
report to Utah Department of Water Rights.

Reporting
USS and Geneva will document the field work and will submit a Status Letter to UDEQ
to summarize the abandonment activities after completion.

Schedule
The work is anticipated to take place in March 2024, depending on driller availability.
UDEQ will be notified at least 14 days prior to the start of field activities to allow the
opportunity to be present if desired. AECOM, a contractor to USS and Geneva, will
conduct the field work.

Please contact us at your convenience if you have any questions on this matter.

SWMU is closed CACWC. Monitoring
network established in the approved
LROF/HHRE, these wells are not included in
the network and therefore will not be needed
for SMP sampling. The SMP is currently
being developed and will be submitted in the
near future.

monitoring the SWMU in the SMP that is
currently being developed and will be
submitted in the near future.
