Union in Midvale, Utah, namely suites: #36 (formerly Shoe Repair) an #38 (It’s About Time). Reference Figures 1 and 2 for general and site-specific, location maps. Figure 3 identifies individual tenant suites located within the shopping mall area, including suite #34 a former dry cleaning operation. As proposed in our August 2023 summary report, suites #36 and #38 were the only tenant suites proposed for sampling in November because all other suites’ indoor air analyte concentrations were below corollary United States Environmental Protection Agency (US EPA) Commercial Indoor Air Vapor Intrusion Screening Levels (VISLs) during at least the prior three sampling events (January, April, and August 2023). As of the January 2023 sampling event, the UDEQ apprised Stantec that any suites not sampled may require sampling as part of final VCP site closure proceedings. Each indoor air sample was analyzed for the following Volatile Organic Compounds (VOCs) by Method TO-15 Selected Ion Monitoring (SIM): tetrachloroethylene (aka, perchloroethylene, ‘PERC’, or PCE) and possible PCE degradative byproducts trichloroethylene (TCE); cis- and trans- dichloroethylene (cis/trans-DCE); 1,2-dichloroethane (1,2-DCA); and vinyl chloride. Table 1 presents recent indoor air results associated with laboratory Method TO-15 SIM analyses, including the November 2023 results. Table 2 includes historical indoor air results associated with VOC analysis by standard Method TO-15, which includes numerous other VOC constituents besides PCE and its degradative byproducts. The UDEQ, VCP and Site Centers agreed that indoor air sampling events conducted after the March 2017 sampling event would be performed for PCE and its five degradative byproducts by the SIM method, in order for the laboratory to lower its Method Detection and Reporting Limits to satisfy corollary US EPA Commercial Indoor Air VISL concentrations of low micrograms per cubic meter (i.e., µg/m3). In summary, all analyte concentrations were below corollary VISLs, except for TCE in suite #38 (It’s About Time) at 3.2 µg/m3, which exceeded the TCE VISL of 2.99 µg/m3. TCE was detected in suite #36 (Shoe Repair) at 1.3 µg/m3, which is below the TCE VISL. SUMMARY REPORT FOR NOVEMBER 2023 INDOOR AIR SAMPLING EVENT NOVEMBER 2023 INDOOR AIR SAMPLING EVENT December 29, 2023 V//230706007/05-reports/delivs/2023/novSumRept 2.1 2.0 NOVEMBER 2023 INDOOR AIR SAMPLING EVENT 2.1 SAMPLING PROTOCOL On November 17, 2023, Stantec collected indoor air samples from two of the 11 suites sampled in the past and most recently during August 2023. Stantec collected indoor air samples at similar locations and in similar fashion as previous sampling events, including hand-delivery of the samples to the laboratory on November 17, 2023. Each indoor air sample was collected in a 6-liter, stainless-steel, individually-certified, summaTM canister, equipped with a laboratory-certified, 8-hour flow rate regulator that was provided by ALS Laboratories of Salt Lake City, Utah. Sampling locations within each suite were similar to historical sampling locations, typically representative of areas where tenant employees spend the majority of their workday, such as registers, office desks, workstations, etc. Sample canisters were located atop the floor at each location, thereby representing a low-elevation, sampling point within each suite. Each summa canister was labeled and hand-delivered to ALS for quantitative analysis of PCE; TCE; cis- and trans-1,2-DCE; 1,2-DCA; and vinyl chloride by the TO- 15 SIM analytical methodology. 2.2 ANALYTICAL RESULTS Table 1 provides a summary of the analytical results associated with the November 17th sampling event and recent analytical results by the TO-15, SIM laboratory method, while historical TO-15 VOC data are presented in Table 2. A copy of the November 2023 laboratory result report is attached as Appendix A. All analyte concentrations were below corollary VISLs, except for TCE (3.2 µg/m3, which exceeded its VISL of 2.99 µg/m3 in Suite #38 (It’s About Time). TCE was detected in suite #36 (Shoe Repair) at 1.3 µg/m3, which is below the TCE VISL. SUMMARY REPORT FOR NOVEMBER 2023 INDOOR AIR SAMPLING EVENT QUALITY ASSURANCE AND QUALITY CONTROL December 29, 2023 V//230706007/05-reports/delivs/2023/novSumRept 3.1 3.0 QUALITY ASSURANCE AND QUALITY CONTROL The following sections discuss the Quality Assurance/Quality Control (QA/QC) measures utilized during the indoor air sampling event. 3.1 SAMPLE REQUIREMENTS, CONTAINERS, AND PRESERVATION All summa canisters and dedicated regulators were provided and certified by the laboratory. All summa canisters were hand-delivered by Stantec staff to the laboratory the same day as sample collection. 3.2 CHAIN-OF-CUSTODY, HOLDING TIME, AND RECORD KEEPING Chain-of-Custody, sample labeling, and record keeping procedures were in accordance with measures used previously and are deemed adequate for the objectives of the project. The sample canisters remained in secure custody of the sampler until hand-delivery to the laboratory. Samples were analyzed within prescribed Holding Times and the results are deemed adequate for use. In summary, the results are deemed satisfactory and useable for this investigation. 3.3 CROSS-CONTAMINATION All summaTM canisters were provided by the laboratory, and each canister and regulator were individually-cleaned and certified, prior to sample collection. Stantec’s sampler wore nitrile gloves during sampling activities. 3.4 DATA QUALITY INDICATORS AND QA/QC SAMPLES The laboratory’s Quality Control Report, included within Appendix A herein, reports that the percent recovery for vinyl chloride in the Laboratory Control Sample (LCS) was slightly lower (66.2%) than the Control Limit (66.9%). It must be noted that vinyl chloride has not been quantified within any of the 11 suites during the past several sampling events and appears to pose little to no risk at this particular site. Laboratory data reporting requisites were similar to historical analytical protocol and methodologies, and appear valid and reflect adequate precision, accuracy, representativeness, completeness, and comparability (PARCC) and to be otherwise adequate for their intended use. Stantec’s comparative analysis of historical air quality results and QA/QC data indicate that the November 2023 analytical results appear valid and useable for ongoing monitoring of progress toward satisfying corollary VISL Cleanup Levels. SUMMARY REPORT FOR NOVEMBER 2023 INDOOR AIR SAMPLING EVENT RECOMMENDATIONS December 29, 2023 V//230706007/05-reports/delivs/2023/novSumRept 4.1 4.0 RECOMMENDATIONS We propose that indoor air samples be collected from only suite #38 (It’s About Time) during the next scheduled sampling event in February 2024, since the suite #36 (formerly Shoe Repair) analytical results have been below all corollary VISL concentrations during both August and November 2023 (i.e., two consecutive sampling events – as proposed in past reports). Stantec proposes that no other indoor air samples be collected during February 2024 from all other suites, considering the recent and historical VOC results and fact that indoor air quality within these specific suites has satisfied corollary VISLs, recently. Stantec proposes that, if suite #38 satisfies all corollary PCE, TCE, and byproduct VISL concentrations during the February 2024 sampling event, then Stantec will conduct two consecutive, semi-annual sampling events that include sampling/analysis of all 11 suites. The semi-annual sampling events are proposed for generalized Spring and Fall timeframes and will entail similar sampling locations, protocol, and SIM laboratory analysis as practiced historically. If the two semi-annual sampling events indicate that all 11 suites satisfy all VISL (Commercial) concentrations, then Site Centers proposes formal UDEQ “Closure” of the VCP project, including Stantec’s decommissioning of the two soil vapor extraction (SVE) vacuum units and cement grout abandonment of groundwater monitoring well MW-2 and all sub-slab soil gas probes - based on current and ongoing, projected-future Commercial land use. In the event that suite #38 does not satisfy all VISLs, then this lone suite will be sampled on a quarterly basis until all corollary VISL concentrations are satisfied during two consecutive, quarterly sampling events – at which time, the above-proposed, semi-annual sampling program at all 11 suites will commence. In the event that one or more of the 11 suites does not satisfy all VISLs during any future sampling event, then only those corresponding suite(s) would be sampled on a quarterly basis - until all corollary VISL concentrations in those specific suites are satisfied during two consecutive, quarterly sampling events. Once the suite(s) of concern satisfy all corollary VISL concentrations for two consecutive quarterly sampling events, then we propose implementing the above-proposed, semi-annual sampling program at all 11 suites in pursuit of VCP project closure. Once all 11 suites achieve two consecutive, semi-annual sampling events that satisfy VISLs, then Site Centers would request formal UDEQ VCP project closure.
