Project No.: 268970.2019

Subject: Fourth Quarter 2019 SVE System Update Mullins Rubber Products 2949 Valley Pike Dayton, OH 45404

In order to address the presence of volatile organic compounds (VOCs), primarily Tetrachloroethene (PCE) and Trichloroethene (TCE) in the subsurface, Mullins Rubber Products has:

Implemented the pilot-scale Soil Vapor Extraction (SVE) system to treat VOCs in unsaturatedsoils in January 2016;

Based on successful implementation of the pilot-scale SVE system and the results of the May 2016Supplemental Source Area Investigation to evaluate other potential source areas, expanded theSVE system to include two additional recovery wells in January 2017; and,

Installed an emulsified zero valent iron (eZVI) treatment zone along the western propertyboundary in January 2017 to address impacted groundwater before it leaves the property.

Summary of Activities

This report details the operations and maintenance (O&M) activities performed at the Mullins Rubber Products facility at 2949 Valley Pike in Dayton, Ohio on December 10, 2019. This visit marks the final quarterly O&M visit to the site in 2019.

The O&M tasks performed in Q4 2019 include the following:

Collection of one blower influent vapor sample from the SVE treatment system. The SVE systemlayout is presented in Figure 1. Laboratory results of the vapor sampling are summarized inTable 1. Complete laboratory analytical reports are included in Attachment A.

953549


Recording of system measurements at all SVE monitoring points, SVE wells, and the SVE blower as summarized in Attachment B. The parameters recorded at these locations included:

— Air flow

— Temperature

— Vacuum

Inspection of the SVE blower and routine maintenance as needed (e.g., change oil, add grease for lubrication, empty condensate collection tank).

Collection of water levels from onsite monitoring wells MW-EPA-08, MW-01R, MW-02, MW-EPA-07, and MW-PW; as well as offsite monitoring wells MW-EPA-14 and MW-04. A summary of the water level data collected from the accessible monitoring wells during December 2019 is included in Table 2.

Collection of groundwater samples from monitoring wells MW-EPA-08, MW-EPA-14, and MW-04. Laboratory results are summarized in Table 3 and the complete laboratory analytical report is included in Attachment A. Groundwater parameters collected during field sampling are included in Attachment C.

SVE System Performance

Prior to the October 2018 monthly O&M visit, the two granular activated carbon (GAC) vessels were disconnected from the SVE treatment system due to carbon saturation. With the carbon vessels no longer connected to the SVE treatment system, TRC has been monitoring the blower influent vapor streams as of October 2018. Table 1 shows the complete analytical laboratory results of VOC concentrations measured during O&M visits, as well as calculated values reflecting the daily amounts of VOCs collected from the subsurface and the amount discharged into the atmosphere.

The amount of VOCs discharged daily to the atmosphere are required to be below 10 pounds per day per the de Minimis source exemption specified in Ohio Administration Code (OAC) 3745-15-05. Currently, calculated discharge rates to the atmosphere continue to be below the discharge limit, as observed in December 2019 to be at 0.0036 pounds per day. TRC will continue to monitor vapor discharge levels on a quarterly basis throughout 2020. If emission levels approach 25% of the OAC exemption limit at any time in the future, the SVE system will be shut down to replace carbon and put the GAC vessels back on line.

Table 1 also includes the cumulative total mass of VOCs recovered during the lifespan of the SVE system. To date, the SVE treatment system has recovered 964.95 pounds of VOCs. The complete analytical laboratory report from the most recent vapor sampling event in December can be found in Attachment A.


Figure 2 presents the vapor influent sample PCE and TCE concentrations over the course of the SVE treatment system’s lifespan. Start-up dates for the SVE Pilot Test including the original three (3) recovery wells and the full scale SVE system expanded to five (5) recovery wells are indicated in the figure to demonstrate the effect of these events on system performance. Figure 2 generally shows a steady decrease in recovery of PCE and TCE recovery over time.

Field measurements of the SVE treatment system are recorded quarterly to gauge the effectiveness and efficiency of the overall system. These measurements are recorded on O&M log forms that are kept on record by TRC. Attachment B summarizes the quarterly SVE O&M measurements. Based on these quarterly data, vacuum continues to propagate through each SVE monitoring point in the subsurface. These vacuum measurements are reflected in the radii of influence shown in Figure 1.

Groundwater Conditions

Static water elevations collected from the six onsite wells and two offsite wells and their resulting groundwater elevations are summarized in Table 2. Groundwater elevation data was used to develop an updated groundwater flow map as reflected in Figure 3. Groundwater flow is westerly from the source area though the eZVI groundwater treatment zone depicted in Figure 4. The historic water level data has shown that groundwater elevation remains relatively consistent throughout the year, corresponding with a westerly flow direction.

Groundwater samples were collected from monitoring wells MW-04, MW-EPA-14, and MW-EPA-08 during the O&M visit on December 10, 2019. Groundwater sampling results from these three wells are shown in Table 3 and the associated Mann-Kendall trend analyses graphs. Groundwater collection parameters for each well are shown in Attachment C.

Results of the most recent groundwater sampling event show that PCE levels in MW-EPA-08 and MW-EPA-14 have increased since these monitoring wells were last sampled in September 2019. This increase is not consistent with recent historic decreases in PCE levels in these monitoring wells as noted in Table 3 and the attached Mann-Kendall graphs. Data from the next scheduled sampling event in March 2020 will be evaluated to assess if this increase in PCE levels is an anomaly or indication of a new upward trend. TCE and cis-1,2 Dichloroethane levels above laboratory quantitation limits were also reported for the first time in MW-EPA-14. These are likely to be breakdown products of PCE de-chlorination. PCE levels in monitoring well MW-04 remain consistent with historical data.

Projected Work for the Next Reporting Periods TRC is scheduled to be onsite again in March 2020 to perform the next quarterly (Q1 2020) O&M

site visit. TRC will coordinate with Mullins Rubber at least 2 weeks prior to visiting the site to perform the Q1 2020 O&M activities. TRC will continue to monitor SVE emission levels via


vapor sampling of the blower influent stream. Groundwater samples will also be collected from monitoring wells MW-04, MW-EPA-14, and MW-EPA-08 during the upcoming O&M visit.

Receipt

The sample was received on 12/16/2019 3:00 PM; the sample arrived in good condition, properly preserved and, where required, on ice.

Air - GC/MS VOA Methods TO 15 LL, TO-14A, TO-15: EPA methods TO-14A and TO-15 specify the use of humidified "zero air" as the blank reagent for canister cleaning, instrument calibration and sample analysis. Ultra-high purity humidified nitrogen from a cryogenic reservoir is used in

place of "zero air" by Eurofins TestAmerica Knoxville.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
