Dear Ms. Anderson:
WSP USA, Inc. (WSP) on behalf of GE Vernova is providing this response to comments
received from the Utah Department of Environmental Quality (UDEQ), Division of Environmental
Response and Remediation (DERR) on the Groundwater Remedial Action Plan Addendum
(dated October 22, 2024) for the former GE Vernova facility located at 130 East 1100 North, in
North Salt Lake, Utah (Site). In addition, this document addresses comments received on the
September 2024 Plume Analytics Report (dated November 1, 2024) for the Site.
The UDEQ DERR comments, dated February 18, 2025, are presented below, and followed by
GE Vernova’s response. It is clear based on DERR’s Specific Comment 1, and the responses
provided, that the process to achieve risk-based closure at this Site remains unresolved and
further discussion is warranted.
GE maintains MNA as the appropriate remedial action for chlorinated VOCs and monitoring as
the appropriate action selected to address 1,4-dioxane. Alternative remedial actions are neither
cost-effective nor technically viable for 1,4-dioxane.

meet the Performance Objectives and goals in the Groundwater RAP Addendum.
a. The historical groundwater data set does not demonstrate a clear and meaningful
trend of decreasing contaminant mass and/or concentration over time in MW-3
and MW-17. These locations are considered one of several appropriate monitoring
points to gauge the effectiveness of MNA.
Response: After discussions with the DERR on the use of MNA as the selected
groundwater remedy for the Site, submittal of the initial Groundwater RAP Addendum in
July 2024 which identified MNA as the selected remedy for groundwater, discussion on
the RAP Addendum with the DERR in August 2024, and revision and resubmittal of the
RAP Addendum in October 2024 to address the DERR’s stated concerns, the DERR
now indicates there is insufficient evidence to document that natural attenuation is
occurring and thus MNA cannot be the selected remedy for the Site.
The Plume Analytics reports that have been submitted to the DERR on a regular basis
have provided strong documentation of the natural attenuation and degradation of the
chlorinated volatile organic compounds (VOCs) at the Site. The non-chlorinated VOC,
1,4-dioxane, was shown to have migrated off-site at low-level concentrations which were
generally detected above the screening level of 0.46 µg/L (WSP, Groundwater Plume
Analytics® Report, November 2024 and March 2025).
Although it is acknowledged that the September 2024 monitoring event was associated
with higher concentrations of cis-1,2-dichloroethene (cis-1,2-DCE) at MW-17 (110 µg/L)
and of 1,4-dioxane at MW-3 (88 µg/L) and MW-17 (17 µg/L), the Utah regulations
specifically note that that “[c]onsideration will be given to naturally occurring variations in
groundwater contaminant concentrations, natural groundwater flow, and dispersion”.1
During the March 2025 monitoring event, the concentration of cis-1,2-DCE at MW-17
decreased approximately 51 percent to 54 µg/L. The concentration of 1,4-dioxane at
MW-3 decreased approximately 33 percent to 59 µg/L, and at MW-17, the concentration
of 1,4-dioxane decreased approximately 41 percent to 10 µg/L.
In the June 2024 Technical Memorandum on the Potential Risk Associated with 1,4-
Dioxane in groundwater, it was demonstrated there was no risk associated with the on-
site groundwater, and off-site groundwater with 1,4-dioxane concentrations were
associated with a residential cancer risk at the midpoint of the acceptable target cancer
risk range if groundwater were used as a potable water supply. There are no residential
receptors located off-site and shallow groundwater associated with the off-site detections
of 1,4-dioxane is not used as a source of water supply. The off-site risk associated with
the potential vapor intrusion of 1,4-dioxane to indoor air was acceptable. The March
2025 groundwater data associated with the off-site monitoring wells had similar

Non-Degradation, R-315-101-3(a).

concentrations of 1,4-dioxane with analytical results ranging from non-detect to 4 µg/L
(off-site MW-A2).
In response to DERR Comment 8 below, GE Vernova will continue to monitor off-site
groundwater for the presence of 1,4-dioxane for a minimum of two years (four semi-
annual events starting with the March 2025 event) to determine additional monitoring
requirements, or if the off-site groundwater monitoring program can be terminated.
Although the presence of chlorinated VOCs in off-site groundwater has already been
addressed and documented to be associated with an off-site release that is not
associated with the former GE Vernova Facility, in accordance with the approved off-site
groundwater monitoring program, select wells will also continue to be monitored for
chlorinated VOCs.
The remaining response presented here for Comment 1a focuses on 1,4-dioxane. The
specific concentrations of VOCs in groundwater at the Site are discussed in response to
Comment 1b (below).
Evaluation of the on-site groundwater data indicates that during the last ten 2
groundwater monitoring events, 1,4-dioxane has only been detected at concentrations
above the Performance Objective of 46 micrograms per liter (µg/L) at MW-3. Detected
concentrations of 1,4-dioxane at the other monitoring wells present at the Site, including
at the property boundary, are below the Performance Objective. In accordance with the
Utah Code for the Voluntary Cleanup Program 3 at 19-8-110(5), there is flexibility built
into the rules to allow the DERR to not require removal or remedy of all discharges,
releases, etc., as quoted below:
“After considering the proposed future use of the property that is the subject of
the agreement, the executive director may approve work plans and reports
submitted under this section that do not require removal or remedy of all
discharges, releases, and threatened releases on the property if the applicant's
response actions under the agreement:
(a) will be completed in a manner that protects human health and the
environment;
(b) will not cause, contribute to, or exacerbate discharges, releases, or
threatened releases on the property that are not required to be removed
or remedied under the work plan; and
(c) will not interfere with or substantially increase the costs of response
actions to address any remaining discharges, releases, or threatened
releases resulting from releases initially generated on the property.”
2 USEPA’s ProUCL User’s Guide (2022) recommends ten sampling points for the calculation of a 95
percent upper confidence limit (UCL).

Response to Comments Groundwater RAP Addendum
-102 July 7,
As noted in the Groundwater RAP Addendum and discussed in previous submittals, the
constituents of concern (COCs) in shallow groundwater do not have the potential to
migrate vertically to deeper groundwater that is used as a source of potable water supply
(i.e., the municipal well). There are no residential receptors downgradient of the Site and
the Site is currently vacant. The only potentially complete migration pathway associated
with the Site and downgradient locations is considered to be the potential for vapor
intrusion from groundwater to indoor air, and the 1,4-dioxane concentrations in both on-
site and off-site groundwater were demonstrated in the RAP Addendum to be well below
the corresponding residential and industrial vapor intrusion screening levels (VISLs). In
addition, the environmental covenant to be placed on the Site will preclude future
residential development and, with the use of engineering and other site administrative
controls placed upon the property, will also prevent the future use of on-site groundwater
as a source of potable water supply.
With the flexibility incorporated into the Statute, the placement of the environmental
covenant on the property to preclude future residential development and prevent use of
on-site groundwater, and the continuation of the off-site groundwater monitoring program
for a minimum of an additional two years, there does not seem to be a reason for a
costly active remedial alternative (e.g., injection) to address the presence of 1,4-dioxane
at one well (MW-3) when there is no potential for adverse exposure to 1,4-dioxane in
either on-site or off-site groundwater. As noted, the continuation of the off-site
groundwater monitoring program for 1,4-dioxane will allow for the continued evaluation
of 1,4-dioxane concentrations, potential receptors, and corresponding off-site risk
associated with the low-level detections of 1,4-dioxane in off-site groundwater.
For determination of the appropriate corrective action at a site, the regulations (R315-
101-1(c) indicate that the following criteria shall be considered in the order of
importance:
(1) the impact or potential impact of the contamination on human health;
(2) the impact or potential impact of the contamination on the environment;
(3) the technologies available for use in cleanup; and
(4) economic considerations and cost-effectiveness of cleanup options.
GE Vernova has demonstrated that there is no current or reasonably foreseeable future
impact or potential impact to human health or the environment, either on-site or off-site,
due to the presence of 1,4-dioxane in groundwater. It is proposed that in response to this
comment, the Groundwater RAP Addendum be revised to present our current findings
with regard to the cost associated with an “active” remedial alternative to address 1,4-
dioxane in groundwater at MW-3, which given there is no potential for exposure to COCs
in groundwater, is not cost-effective. Therefore, monitoring by itself is considered the
alternative selected to continue to evaluate 1,4-dioxane.
The selection of MNA is appropriate for the chlorinated VOCs which is discussed further
in response to Comment 1b below.
Response to Comments Groundwater RAP Addendum
-102 July 7,
b. The concentrations from the September 2024 groundwater monitoring event were
above the Proposed Performance Objectives in MW-3 (1,4-Dioxane - 88 µg/L compared to
the goal of 46 µg/L) and MW-17 (cis-1,2 DCE - 110 µg/L compared to the goal of 70 µg/L).
Response: As noted in the response to Comment 1a above, the DERR recognizes the
potential for fluctuation in groundwater concentrations [R-315-101-3(a)]. The fluctuations
observed at MW-3 and MW-17 during the September 2024 groundwater monitoring
event are believed to have been associated with the seasonally lower groundwater
levels and its impact on the migration of constituents bound in the smear zone from soil
to groundwater. Data were added to the response to Comment 1a (above) to
demonstrate how concentrations at these two wells have decreased since the
September 2024 event. In addition, the environmental covenant to be placed on the Site
will preclude future residential development and, with the use of engineering and other
site administrative controls placed upon the property, will also prevent the future use of
on-site groundwater as a source of potable water supply.
The need to further discuss the requirement for an active remediation to address 1,4-
dioxane in on-site groundwater was discussed in the response to Comment 1a above.
The concentrations of the VOCs (including 1,4-dioxane) in comparison to the
Performance Objectives are discussed herein along with selection of MNA as an
appropriate remedy for the chlorinated VOCs.
In Comment 7 below, the DERR indicates that compliance with the Performance
Objectives is not on an individual concentration basis but is instead based on the 95
percent upper confidence limit (95% UCL) on the arithmetic average for data collected
from an individual well. This approach is very conservative because if groundwater were
being used, it would be drawn from a radius of influence around a well resulting in the
mixing of groundwater from several, if not many of the wells located at the Site.
Evaluation of the data indicates that only cis-1,2-DCE and 1,4-dioxane have individual
detections within the last 10 events that exceed the Performance Objectives. The well-
specific 95% UCLs for these constituents at applicable monitoring wells are summarized
in Table 1 below. With the exception of cis-1,2-DCE and 1,4-dioxane at MW-3, the 95%
UCLs for all of the individual wells are below the corresponding Performance Objectives.
Specifically, the 95% UCL for cis-1,2-DCE at MW-17 of 59.85 µg/L is below the
Performance Objective of 70 µg/L.
The DERR’s position on the need for an active remedy seems to focus on MW-3 where
the 95% UCLs for cis-1,2-DCE and 1,4-dioxane exceed the corresponding Performance
Objectives. As noted, MW-3 is located on the former facility where there is no current
potential exposure to groundwater and where future potential exposures will be
prevented by the use of the environmental covenant.

concentrations were not of concern for meeting the Performance Objectives (see Attachment 1).
The Groundwater Plume Analytics® Services report for the Site (WSP, March 2025) indicates
that between September 2021 to March 2025, the on-site TCE area in acres was stable, with its
average concentration, and plume mass indicator (lbs) exhibiting decreasing trends with
confidence levels in the regression analyses and Mann-Kendall trends ranging from 97%
(regression analysis and Mann-Kendall trend confidence level for decreasing average
concentration and plume mass indicator) to 99% (Mann-Kendall trend confidence level for
decreasing average TCE concentration). Cis-1,2-DCE, a breakdown product of TCE, shows
stable trends for area, average concentration and mass. The on-site 1,1-DCE plume exhibits a
decreasing trend in average concentration and decreasing/no trend for area or mass. The on-
site 1,1-DCA plume exhibits decreasing trends in area, average concentration, and mass with
confidence levels at 99% for both regression analysis and Mann-Kendall trends. These data
analyses support the continuing MNA of the chlorinated VOCs of concern in Site groundwater.
c. The “Full Plume Area” and “Full Plume Mass Indicator” noted in the groundwater
model for 1,4-Dioxane was greater in September 2024 (10.1 acres and 0.82 lbs,
respectively) as compared to December 2022 (8.2 acres and 0.69 lbs, respectively). This
suggests the overall plume may not be attenuating at a rate necessary to achieve the
project goals. The December 2022 sampling event was one of the first events to include
on and off-site data and provides a reasonable overview of baseline conditions to help
gauge the rate and level of attenuation when compared to current data.
Response: As noted in the responses to the previous comments, the UDERR regulations
acknowledge that there is going to be some fluctuation in groundwater data. The current

Groundwater Plume Analytics® Services report for the Site for March 2025 indicates that
between September 2021 to March 2025 the area of 1,4-dioxane on-site decreased 10 percent,
the average concentration decreased 51 percent, and the mass indicator decreased 56%.
See response to Comment 1a with respect to the need to conduct an active remediation of 1,4-
dioxane in groundwater.
2. Page 8, Proposed Performance Objectives for On-site Groundwater: Please revise the
text to note that the goal of the remedial efforts is to meet the Performance Objectives in
Table 2 and ensure the off-site impacts associated with the site do not pose an
unacceptable risk.
Response: The text under the Proposed Performance Objectives will be revised to
indicate: “The overall remedial objective is to meet the Performance Objectives in Table
2 for on-site groundwater and to ensure the impacts to off-site groundwater do not pose
an unacceptable risk. The Performance Objectives for each COC, the Basis of each
Performance Objective, and the range of detected concentrations for each COC are
summarized below“.
3. Page 8, Proposed Performance Objectives for On-site Groundwater: Arsenic
concentrations will be screened against the MCL. Please revise the text.
Response: Table 2 will be revised to identify the Performance Objective for arsenic of
10 micrograms per liter (µg/L) with the Basis of Performance Objective identified as the
Maximum Contaminant Level (MCL).
4. Page 10, Third Bullet: Please remove the wording “other than the geologic setting” from
this sentence.
Response: There is no objection to removing the phrase “other than the geologic setting”
under the discussion of the selected performance criterion for arsenic. However,
placement of the environmental covenant will prevent potable use of groundwater,
resulting in achievement of the onsite performance objective for arsenic.
5. Page 10, Application of Performance Objectives: Please remove the sentence “GE is
awaiting on comments on the proposed modifications.” The DERR has accepted the
proposed modifications to the on-site groundwater monitoring program by way of this
comment. The approach will be incorporated into the RAP along with the criteria in
Specific Comment #8.
Response: The identified phrase will be deleted and the text will be updated to reflect
UDERR’s approval of the modifications to the on-site groundwater monitoring program.

met and will continue to be met.
Response: The comment is worded such that there will be no end to long-term
monitoring. Instead, the following text is proposed, “Sampling of select VOCs will
continue until data indicate the performance objectives have been met. At this point, in
general accordance with the USEPA guidance (1998*), an additional four semi-annual
groundwater monitoring events (two years) will be conducted to confirm that
concentrations of VOCs in groundwater remain below the Performance Objectives”.
* USEPA’s Technical Protocol for Evaluating Natural Attenuation of Chlorinated Solvents in Ground Water (1998)
7. Page 11, Application of Performance Standards: Please revise the text to clarify if the
95% UCL will represent individual well data or site-wide data. The DERR cannot accept
site-wide data for the entire plume to make decisions on whether the remedial goals have
been met. Individual well data will be evaluated.
Response: The text will be revised to indicate the “primary mechanism to evaluate Site-
wide achievement of the performance objective will be the calculation of an individual-
well specific 95% UCL for the COC of interest”. Additional supporting site-specific
information will be presented as appropriate to put the data in perspective, specifically
noting an exceedance at a single well in the interior of the site would not mean that the
site in its entirety would not meet the performance objective if site boundary wells meet
the performance objectives
8. Page 11, Application of Performance Standards, third paragraph: Please revise the text
to note that off-site groundwater monitoring will commence for a minimum of two years
and the data will then be evaluated before determining additional monitoring
requirements. The purpose of the off- site monitoring is to ensure there are no changing
conditions and unacceptable risk.
Response: The concluding paragraph on the Application of Performance Standards will
be revised to indicate GE Vernova will continue to monitor off-site groundwater for the
presence of 1,4-dioxane for a minimum of two years (four semi-annual events starting
with the March 2025 event) to determine additional monitoring requirements, or if the off-
site groundwater monitoring program can be terminated. In accordance with the
approved off-site groundwater monitoring program, select wells will also continue to be
monitored for chlorinated VOCs.
9. Page 12, Final Report and Certificate of Completion: Please submit a report with each
groundwater monitoring event. A Final Report should be submitted with a request for
closure once the cleanup goals have been met, there are no spikes in the data and the
plume is considered stable and decreasing. A Site Management Plan and Environmental
Covenant will need to be finalized prior to final closure to document the long term
obligations associated with the site.
Response to Comments Groundwater RAP Addendum
-102 July 7,
Response: At DERR’s request, a semi-annual monitoring report will be provided after
each groundwater monitoring event. The Final Report will be submitted with a request
for closure when the groundwater data meet the necessary requirements. It is
understood the Site Management Plan and Environmental Covenant will be finalized
prior to final closure to document any remaining long-term obligations associated with
the Site.
DERR Review Comments September 2024 Plume Analytics Report
Technical Comment:
Slide 30: The 1,4 Dioxane concentration in MW-3 for the September 2024 sampling event
is reported as 94 ug/L, which does not match the result from the on-site September 2024
Groundwater Monitoring Report. Please revise.
Response: DUP1-0191224 (duplicate) was collected from MW-3, and the result of the
duplicate was 94 ug/L. The September 2024 Plume Analytics Report included the
duplicate concentration since it was the highest concentration in MW-3 for the
groundwater monitoring event, and no revision of the report is warranted.
The process to achieve risk-based closure at this Site remains unresolved. Therefore,
groundwater monitoring under the accepted on- and off-site programs, with reports provided to
the DERR on the existing semi-annual schedule, will continue.
At this time, if requested by the DERR, the Groundwater RAP Addendum will be revised to
identify monitoring as the action selected to address 1,4-dioxane and MNA as the remedial
action for chlorinated VOCs. Alternative remedial actions are neither cost-effective nor
technically viable for 1,4-dioxane.
Please contact Brad Glisson at brad.glisson@wsp.com if you have any questions or comments
regarding this report or would like to set up a conference call to discuss.
