John Russell/Site Centers UPDATE

Hello Joe – I know how busy you and your VCP colleagues are, currently……thus, I thought that I’d propose
something to you for your email feedback. We just completed the Jan. 2023 indoor air sampling event at The Shops
at Ft. Union within all 11 suites. I am preparing the Summary Report, currently.

Rather than emailing you a rough draft report, I intend to send you the final Jan. 2023 Summary Report via
email. We already know that the UDEQ will want more sampling, so there’s no reason to send a ‘draft’ report….as you
have not had time to respond to the Oct.ro- draft report; we had very high TCE concs. during the Oct. sampling event;
and we haven’t generated sufficient data to support any “downward trends,” etc…..at least, not yet.

In a nutshell, we observed decreases in all TCE concentrations; increases in PCE concs. in 4 suites but below PCE
VISL; and had VISL exceedances for TCE and 1,2,-DCA. We’ve seen similar decreases in TCE and then observed
‘rebounds’ in TCE and VOC concs., historically. We’ll “Recommend” continuing Quarterly sampling for the short-
term……hopefully, we’ll observe a couple of consecutive ‘downward’ trends in TCE concs., etc….and then we can
discuss the path to closure, etc.

I also intend to recommend that we drop/stop sampling 3 suites that have been clean for quite a while….trying to
save Site Centers some monies, etc. [Suites #52 (ULTA), #56 (Smiths), and #42 (MWJD)]. IF needed before final
closure, we could circle-back and sample those suites one final time for confirmation, if pressed, etc.

Thoughts ??, whenever convenient for you - John

Hello Joe – Sounds fine. I’ll plant to have Rich Pratt coordinate w/field geo. Cody Fauth…or Rich himself…for a mid-
to later-April sampling event. I believe Cody may still be working in AK, even in a few weeks, etc.

I believe that a new prospective shop-mall purchaser is considering buying the mall….CONFIDENTIAL – but that was
reported to me, several weeks ago by another env. consultant and law firm, conducting due diligence for a Confidential
client.

Thank you for the timely feedback. Have an enjoyable weekend…I imagine Team Katz is sledding a lot, these wintry
days!.....whether for fun…or simply trying to walk to get the mail – ha. John

Hello John,

Thanks for sending this report. I will look through it and get back to you. I do not anticipate objections to removing the
three repeatedly non-detect suites from routine monitoring, particularily if there are no objections to including them in a
final round of sampling for confirmation purposes, but I will need to discuss it with the team as well as have an overall
discussion of the site. I will try to push this as soon as possible so you have adequate time to prepare an April sampling
event.

Please let me know if you have any questions.

Thanks,

Joe

Hello Joe – Recently, I received a new Site Centers contract for routine sampling in 2023 top conduct routine 2023
sampling. I had been waiting for the contract before submitting the attached report, which proposes April sampling.

We intend to conduct another indoor air sampling round at The Shops at Ft. Union in ~ mid- or-so April. Our client
asked that I inquire of you/UDEQ – as we propose in the attached, very brief 4-page report, can we NOT sample the
following 3 suites, which have been clean for at least the past couple of sampling events: Suites #52 (ULTA), #56
(Smiths), and #42 (MWJD)….??

We can always sample them as part of final site closure, etc. in the future….to verify clean, etc. Thoughts ? Thank

Hello Rich and Joe –

RICH…….let’s plan on including Suite #42 for this next sampling event. Site Centers had asked that we try and delete
as many suites as deemed satisfactory to the UDEQ. Site Centers is simply looking to reduce some costs,
whenever/wherever we can, etc. Even dropping 1 or 2 suites is of interest to Site Centers, simply to reduce total cost,
etc.

If in the future we experience more consecutive results that show a steady decline or ‘ND’ for this suite, then we can
re-examine possibly dropping it from sampling events, etc. John

Hello Rich,

We do not have any concerns about not sampling Suites #52 or #56. The data shows that these have been consistently
below VISLs and mostly non-detect.

We would prefer sampling continue at Suite #42, but could also agree to not sample Suite #42 if we can all agree that
sampling may need to restart at Suite #42 in the future if the data from the surrounding suites show any marked
increases. Given that Suites #42, #44, and #46 are all about equidistant from the locations with the historical highest
concentrations, we would expect their concentrations to be similar; however Suites #44 and #46 seem to be somewhat
higher than Suite #42. Since Suite #42 has not been consistently non-detect like Suites #52 and #56 and is not behaving
quite as expected, there is some low level of concern about not sampling it.

For next week, I am available Tuesday, Wednesday, and Thursday mornings. For the following week, I am pretty open in
the mornings.

Please let me know if you have any questions.

Thanks,

Hello Rich,

Everything is well. I hope you can say the same.

I am sorry about not responding to your prior email regarding the Praxair sampling. Somehow I filed it in another
project folder and it disappeared from my inbox and fell off my radar.

Regarding DDR, I hope to have the official determination tomorrow, but it is likely that not sampling Suites #42, 52, and
56 will be accepted.

Thanks,

Joe

Hello Joe – Attached is Site Centers’ April 2023 Indoor Air Sampling Summary Report…..including an excel
spreadsheet for easier review of lab results (issues converting to a pdf in the report pdf).

As the report notes, unfortly., we were unable to sample a very important Suite #36 (Shoe Repair; next door to dry
cleaners)…..because no one let us know that the tenant went out of business or moved. We will ensure that it is
sampled next time, as this is a crucial suite that was contaminated as recently as the last sampling event in Fall 2022
and previously, etc. All-in-all however, it is evident that cotam. Concs. are decreasing in general.

Let me know if you need anything else in this regard. Thank you, John

Hello Joe – Next Tues. Aug. 8th morning……Rich Pratt will collect this Qtr’s indoor air sampling at The Shops @ Ft.
Union. We will sample 8 of the 11 for this sampling event, dropping Suites #52 (ULTA), #56 (Smiths), and #50 (Office
Max) this time around….as they have been clean for more than past 2 events, etc.

As an aside – Linde is reviewing my final PRAP report…..and I should receive final comments, soon. Per attached lab
report --- All of the last indoor air samples at former Fausts were ND….not surprising though, as the SSDS and HVAC
systems were “off.” The house was ‘hot’ with no mixing of air, etc….and probably a temp-gradient forcing indoor air to
the outside, etc……reasoning doesn’t matter to Linde, at this time and based on a lot of issues…including:

The SW corner sub-slab soil gas sample, collected within couple feet of the closest indoor air sample, had TCE at 70
ug/m3, while the SE corner sub-slab soil gas sample had a TCE conc. of 7.5 ug/m3….and it was collected within 2 ft. of
the indoor air sample. The 2 sub-slab probes are air-tight.

Linde intends to pursue TCE gwater treatment/cleanup, regardless of indoor air. We will submit the PRAP sometime
soon, John
