5 June INTRODUCTION This 2017 Annual Report has been prepared by Golder Associates Inc. (Golder) on behalf of the Soo Line Railroad Company doing business as Canadian Pacific (CP). The purpose of this report is to document the operation of the overburden groundwater remedial system in the southeastern area of the East Side Shoreham Facility in Minneapolis, Minnesota (Facility). The design of the system was presented in the Overburden Groundwater Remedial Design Report (Golder, 2007; Design Report) submitted to the Minnesota Pollution Control Agency (MPCA) in April 2007 and approved by MPCA on April 30, The construction of the system was documented in the Response Action Implementation and Monitoring Report (Golder, 2009; RAIR) submitted to MPCA in April 2009 and subsequently approved. As detailed in the Design Report and the RAIR, the purpose of the system is to address groundwater contamination in shallow overburden near the Roundhouse and deep overburden between the Roundhouse and the intersection of Central Avenue and 28th Avenue, NE. The RAIR documented system operation from startup (November 8, 2007) through September Annual Reports have documented system operations from October 2008 to 2016 (Golder, 2010, 2011, 2012, 2013, 2014a, 2015a, 2016a, 2017). This 2017 Annual Report documents system operation from January 2017 through December This report has been prepared in accordance with MPCA Voluntary Investigation and Cleanup (VIC) Guidance Document #18 (MPCA, 2002). In 2017, a work plan, submitted by CP and approved by MPCA, (Golder 2015c) was implemented for the shutdown and rebound testing of extraction wells RW06-27-BR, RW07-38-I, RW06-28-I, and RW07-40-SP. The shutdown and rebound testing protocol was initiated on July 21, 2017 and continued through the rest of Extraction well RW07-39-SP remains in operation. 2.0 OVERVIEW As stated in the Design Report and consistent with MPCA guidance, the overburden groundwater pumping system was designed to contain contaminated groundwater on an interim basis during upgradient source removal activities until it could be demonstrated that the groundwater plume was stable or decreasing in size, and would remain so without further pumping. The remainder of this section is a general overview, as presented in the RAIR, of the geologic setting, contaminant profile prior to pumping operation, system construction, and remedial goals. As previously described in VIC Site reports, the geology in the vicinity of the Facility is comprised of overburden units including surficial alluvium, till, outwash, and lacustrine clay. Bedrock units include the Ordovician St. Peter sandstone, St. Peter mudstone, and the Shakopee dolomite of the Prairie du Chien group (OPD), any of which can directly underlie the overburden depending on location. For the purposes of remedial design, groundwater has been assigned to the shallow overburden, intermediate overburden, deep overburden, and OPD bedrock. Shallow wells are screened between 793 and 823 feet above mean sea level (ft amsl) in near surface lithologies, including glacial till, outwash, and St. Peter Sandstone. Deep wells are screened between 659 and 699 ft amsl (approximately 70 feet to 150 feet beneath the water table) and correspond primarily to deep outwash in the bedrock valley or equivalent depth in the mudstone unit of the St. Peter Sandstone outside of the bedrock valley. Intermediate wells generally fall between these two designations and are screened between 728 and 805 ft amsl, primarily in outwash and St. Peter Sandstone. Shakopee wells are screened between 614 and 636 ft amsl (approximately 50 feet beneath the top of the OPD). Wells monitored in these four zones are further detailed in Section

6 June The most significant impacts, prior to remediation, in overburden groundwater in the southeastern area at shallow and intermediate depths were located beneath a portion of the Roundhouse footprint at elevations generally greater than 775 ft msl. Geologically, glacial till, shallow outwash, and St. Peter Sandstone units are present within the area of influence of the intermediate depth pumping wells. Active soil source removal by soil excavation (Golder, 2015b) and soil vapor extraction (SVE) was completed in the Southeastern Facility area by CP (Golder, 2014b). The soil source removal, together with the pumping system, has reduced the concentrations in shallow/intermediate overburden groundwater and contained the migration of chlorinated volatile organic compounds (cvocs) from the Roundhouse area (Golder, 2010, 2011, 2012, 2013, 2014a, 2015a, 2016a, 2017). The most significant impacts in deep overburden in the southeastern area prior to system operation were located between the Roundhouse and the intersection of 28 th Avenue and Central Avenue at elevations generally below 775 ft msl. Geologically, the middle and deep outwash are present within the area of influence of the deep overburden pumping system. The soil source removal, together with the pumping system, has reduced the concentrations in the deep overburden groundwater and contained the migration of the cvoc plume. The approved Design Report defined the performance goals for the pumping system, which included the demonstration of hydraulic capture, plume stability, and attenuation. The Design Report also included the results of pumping tests and groundwater modeling used to design the capture zones for the system, based on addressing groundwater containing contaminant levels exceeding 100 ug/l of cvocs. Plume stability was defined as a steady state condition where the plume is no longer increasing in extent, and can be demonstrated by overall stable concentration trends over time in wells located within and surrounding the plume. Attenuation was defined as an overall decrease in plume mass over time and can be demonstrated by decreasing concentration trends, particularly in wells located within the core of the plume, where impacts are highest. The three pumping systems were designed to be operated throughout source removal activities until the associated (shallow/intermediate overburden or deep overburden) groundwater plume was stable or decreasing in size and would continue to do so without further pumping. The southeastern area groundwater extraction and treatment system design included the following primary elements: Five (5) extraction wells, each equipped with an electric, submersible groundwater pump. Two (2) below-grade, double-walled force mains for conveyance of deep overburden groundwater to the treatment building. Three (3) above-grade, heat-traced and insulated force mains for conveyance of intermediate overburden groundwater to the treatment building. Treatment building with secondary containment. A below-grade, gravity discharge pipeline runs from the treatment building to an on-facility manhole located southeast of the treatment building. The manhole links to the city sanitary sewer, conveying the effluent to the Metropolitan Council Environmental Services (MCES) treatment plant. In December 2009, the system was modified to bypass the pre-treatment system and discharge directly to the sanitary sewer system (as detailed in the 2009 Annual Report) as MCES discharge limitations were satisfied without pre-treatment. 2

7 June Following successful completion of the Soil Vapor Extraction (SVE) source removal operations and substantial concentration reductions in extraction well concentrations, CP proposed the shutdown of four of the five extraction wells in MPCA approved the shutdown and rebound testing proposal on May 7, 2017, and CP ceased groundwater extraction at extraction wells RW06-27-BR, RW I, RW I, and RW SP on July 21, The current layout of the system is shown in Figure 1, and construction of the southeastern area groundwater extraction and treatment system was documented in the RAIR (Golder, 2009). Construction details of all pumping and monitoring wells associated with the East Side Extraction and Treatment system are summarized in Table SYSTEM OPERATION The southeastern area pump and treat system has been operating continuously since November 9, 2007 except for brief periods of shutdown related to maintenance. On July 21, 2017, the approved shutdown and rebound testing of extraction wells RW06-27-BR, RW07-38-I, RW06-28-I, and RW07-40-SP was initiated and continued through the rest of 2017, while extraction well RW07-39-SP remained in operation (see Section 4.2). 3.1 Extraction Well Operation and Sampling Total volumes of water extracted from each well during the reporting period, together with average flow rates during operational periods are as follows: RW07-39-SP: 720,310 gallons, 1.37 gpm average RW07-40-SP: 646,851 gallons, 2.22 gpm average RW06-28-I: 1,341,223 gallons, 4.61 gpm average RW07-38-I: 2,630,118 gallons, 9.03 gpm average RW06-27-BR: 3,936,341 gallons, 13.5 gpm average The total volume extracted from all five wells during 2017 was 9,274,843 gallons. The effluent from each extraction well was sampled during the first two quarters. After four wells were shut down in July 2017, the active well (RW07-39-SP) and inactive wells (RW07-40-SP, RW06-28-I, RW07-38-I, and RW06-27-BR) were sampled in the 3 rd quarter and only the active well (RW07-39-SP) was sampled in the 4 th quarter. Table 2 presents the VOC concentrations detected for each sampling event. Table 3 presents the mass removed quarterly and total mass removed through December Mass removal calculations were based on the average of concentrations determined at the beginning and end of each sampling period and the volume extracted during that time. Complete laboratory data are provided in Appendix B. VOCs detected in the groundwater stream include 1,1-DCA, 1,1-DCE, cis-1,2-dce, PCE, 1,1,1-TCA, and TCE. A total of 9.0 pounds of VOCs were removed from the groundwater during the reporting period, and a cumulative total of 385 pounds has been removed since commissioning the system on November 8, 2007 through December 18, The cumulative mass removal of cvocs since startup through the current reporting period is shown on Figure 2. During the reporting period, PCE constituted the largest mass of contaminants removed (3.29 pounds), followed 3

8 June by 1,1-DCA (1.67 pounds), cis-1,2 DCE (1.63 pounds), 1,1,1-TCA (1.49 pounds), 1,1-DCE (0.49 pounds) and TCE (0.46 pounds). 3.2 System Maintenance During the current reporting period (January 2017 to December 2017), the following operation and maintenance issues were addressed: Equipment Repairs and Maintenance April 3-5: A scheduled well rehabilitation (see below for description) of RW06-28-I, RW07-39-SP, RW07-40-SP, and RW07-38-I was conducted by Stevens Drilling and Environmental (SDE). A new pump, motor, and electrical lead was also installed in RW07-39-SP. September 5-8: November 13: December 4-7: A scheduled well rehabilitation of RW06-28-I, RW07-39-SP, RW07-40-SP, and RW07-38-I was conducted by SDE. Flashing was installed to close a gap between the interior walls and containment lip within the treatment building. A scheduled well rehabilitation of RW07-39-SP was conducted by SDE. Outside of these noted maintenance events, all five extraction wells pumped continuously until July 21 and RW07-39-SP pumped continuously throughout the reporting period. Well Rehabilitation The process of well rehabilitation included the following mechanical and chemical treatment steps. First, the drop pipes, pumps and motors were removed from each well for mechanical cleaning, followed by the introduction of a chemical solution comprised of Aquaclear AE and Aquaclear MGA into the wells. Aquaclear AE is a liquid blend of acids and acid enhancers used to remove biological and bacterial fouling. Aquaclear MGA is a dry blend of granular acid and additives for the removal of mineral scaling including from iron, manganese, and carbonate. The acid treatment was surged mechanically within the wells using surge blocks, and the wells were then left undisturbed for 24 hours. At the conclusion of the 24-hour period, each well was redeveloped. The process of redevelopment included alternately pressurizing and depressurizing the water in each well via vertical movement of a surge block to break loose particulates within the screen and well packing, and then using a pump to purge the well water into an aboveground container until the groundwater was observed to be clear. Containerized water from redevelopment was tested with a calibrated ph meter, and sodium bicarbonate slowly added as necessary, until the ph was within permit limits. The water was then discharged to the East Side treatment building sump and co-mingled with the effluent stream, which is then routed to the MCES sanitary sewer for disposal. 4

9 June PERFORMANCE EVALUATION 4.1 Hydraulic Performance The hydraulic performance of the pumping system is assessed based on the groundwater levels measured in monitoring wells within four monitoring zones previously defined for the VIC Site (i.e. Shallow zone, Intermediate zone, Deep zone and OPD 1 ). Groundwater elevations were measured quarterly (March 3, May 12, August and October 6-7) by the Site data collection and data management consultant (AMEC Foster Wheeler) including the following wells in the Southeastern Area groundwater extraction system monitoring network: Shallow zone: MW-406D, MW00-41-T, MW00-42-T, MW00-43-T, MW02-46-T, MW T, MW04-24-T, MW04-25-T, MW04-27-T, MW04-28-T, MW04-31-T, MW04-33-T, MW04-95-T and MW06-01-T Intermediate zone: MW-403D, MW02-46-I, MW04-28-I, MW04-31-SP, MW04-33-SP, MW06-01-I, MW I, MW06-29-I, MW07-41-I, MW07-42-I Deep zone: MW00-42-MS, MW00-43-BR, MW02-46-BR, MW03-56-BR, MW04-26-BR, MW04-29-BR, MW04-30-BR and MW06-01-BR OPD 2 : MW02-01-OPD, MW03-61-OPD, MW04-28-OPD and MW05-01-OPSH The groundwater extraction well water levels are measured monthly by Golder Associates. Figure 1 shows the monitoring and extraction well locations. Hydrographs beginning in March 2007 are shown in Figures 3 to 5 for the monitoring wells in each of the four monitoring zones. From 2007 to 2010, water levels were generally stable from year to year, with seasonal variations evident during the year, particularly during August, which typically exhibited lower water levels than those observed during the rest of the year. In 2011, water levels rose several feet on average and have continued to rise since 2013, with less seasonal variations. Increasing water levels persisted during 2017, with a marked increase in water levels in the Shallow zone during quarters 3 and 4, following the shutdown of extraction wells. The same trends are generally exhibited for the Intermediate to the Deep zone with minor variations, (Figure 3). Water levels in the deeper zones (Figures 4 and 5), generally vary over a smaller range and exhibit less variability from well to well. Contours of groundwater level were developed as one line of evidence in evaluating capture zones, based on synoptic groundwater elevations. Figures 6 to 9 depict the groundwater equipotentials for each of the four quarters in 2017 in the three overburden monitoring zones. The groundwater contours indicate similar flow patterns and zones of pumping influences for the first two monitoring periods of 2017 as have been observed since start up and reported in the RAIR and the subsequent Annual Reports (Golder, 2010, 2011, 2012, 2013, 2014a, 2015a, 2016a). Following the shutdown of four extraction wells, the overall increasing trend in sitewide groundwater elevation was evident. Groundwater remained depressed in the vicinity of the operating extraction well, with a smaller capture zone commensurate with the reduced cumulative pumping rate. Figures 10 and 11 present hydrogeologic cross sections including all of the pumping wells, with Figure 10 presenting the May 2017 data under fully pumping conditions and October 2017 after the shutdown of four 1 Refer to AMEC (2015) for a complete discussion of the monitoring zones. 2 Select OPD wells are included for downgradient hydraulic monitoring control. No pumping is conducted in the OPD. 5

10 June extraction wells. It is noted that upward gradients between the OPD and deep outwash are evident in May 2017, while the natural downward gradients are evident in October In summary, the hydraulic performance data for 2017 show that during the first half of the year the pumping systems operated as originally designed, and following the shutdown in July 2017 the remaining extraction well provided continued mass removal in the overburden aquifer. 4.2 Extraction System Shutdown and Rebound Testing As presented in the Shutdown Evaluation Memorandum (Golder 2015c), substantial concentration reductions in extraction and monitoring well concentrations have been achieved during full-scale operation of the groundwater extraction system. The shutdown and rebound testing plan, approved by MPCA on May 7, 2017, included groundwater sampling to evaluate rebound of VOCs in groundwater. Shallow, intermediate and deep well sampling was conducted in the following wells: Shallow well MW04-95-T Intermediate wells RW07-39-SP, RW07-40-SP, RW06-28-I, MW04-28-I, MW07-41-I and MW07-42-I Deep wells MW00-43-BR, MW04-30-BR and MW04-29-BR The wells listed were sampled monthly for VOCs over three months following shutdown using low flow procedures in accordance with the Site SOP. Sampling was conducted on August 15, September 22, and October 9-17, Total cvoc concentrations for each monitoring well and inactive pumping well included in the testing plan prior to shutdown (May or June 2017) and for the three months immediately following shutdown (August, September, and October 2017) are presented in Figure 12 and concentrations for all sampled wells are listed for all wells in Table 4. In the Shallow zone, total cvoc concentrations continued to decline following shutdown. In the Intermediate zone total cvocs in monitoring well MW04-28-I increased during the August event immediately following shutdown, but demonstrated a decreasing trend in subsequent months. In the deep zone, only monitoring well MW04-30-BR exhibited an increase in total cvoc concentration during the rebound testing. Immediately following shutdown the total cvoc concentration increased from 20 ug/l in May 2017 to 74.7 ug/l in August Concentrations increased further during the second monthly sampling event following shutdown to a total cvoc concentration of ug/l, but then decreased in the third sampling event to 179 ug/l. Other wells in the vicinity of the extraction wells were sampled in the May/June 2017 and October 2017 semiannual events and the cvoc results are listed below: MW06-29-I: 347 ug/l, (May) 106 ug/l (October) MW00-42-MS: 35 ug/l, (May) 27 ug/l (October) RW06-27-BR: 118 ug/l, (June) 12 ug/l (October) MW04-26-BR: 187 ug/l, (May) 506 ug/l (October) 3 The October 2017 sampling event comprised sampling of monitoring wells by AMEC October 9-12, and sampling of extraction wells by Golder on October 17. 6

11 June MW02-01-OPD: 17 ug/l, (May) 20 ug/l (October) MW03-61-OPD: 8 ug/l, (May) 18 ug/l (October) MW04-28-OPD: 40 ug/l, (May) 28 ug/l (October) These results also indicate the lack of rebound throughout the Southeast Area. In particular, it is noted that the OPD wells display an overall lack of rebound, indicating that while some rebound occurred in deep overburden (BR) wells, the OPD was not affected. Based on the continued decline of total cvocss in all monitoring wells except MW04-30-BR and MW04-28-I, which exhibited a short term increase following pump shutdown followed by declines in concentration, the rebound sampling will continue as outlined in Golder, 2015c. 4.3 Routine Semi-annual Groundwater Sampling Groundwater sampling events were conducted semi-annually for the Site by the data collection and data management consultant (AMEC Foster Wheeler) on May 2-8 and October 9-13, These data are reported annually (AMEC, 2018). Isopleths of total cvocs for the October 2017 sampling event are presented for each monitoring zone in Figure 13. In the Shallow zone, total cvocs were less than 100 ug/l in all network monitoring wells. In the Intermediate zone, only a single area remains above 100 ug/l near MW06-29-I and RW07-39-SP, with a maximum concentration of ug/l. In the deep zone, a discrete area above 100 ug/l is present near MW04-26-BR and MW04-30-BR with a maximum concentration of ug/l. The areas of total cvocs over 100 ug/l have decreased substantially in both magnitude and extent over time. Areas above 10,000 ug/l were historically present during pre-pumping conditions, with maximum concentrations in the Shallow, Intermediate and Deep zones of 3,890 ug/l (MW04-95-T), 13,250 ug/l (MW04-28-I), and 14,090 ug/l (MW04-30-BR), respectively. Contaminant mass reduction over time is documented in the concentration-time graphs for the southeastern area monitoring well network presented in Appendix A, which includes the historical data and the data collected during this reporting period. The data show that key monitoring wells in the vicinity of pumping wells have exhibited substantial declines in contaminant levels, of between 98% and >99%, since pumping was initiated. Monitoring wells MW07-42-I and MW07-41-I, proximal to pumping wells RW06-28-I, RW07-39-SP and RW07-40-SP, have shown decreases in cvocs from 3,875 ug/l to 35 ug/l (>99%) and from 5,800 ug/l to 58 ug/l (99%), respectively, since pumping was initiated. In MW06-29-I, which is installed at a deeper interval near these pumping wells, cvocs concentrations have been variable but overall have decreased from 193 ug/l (prior to pumping) to 105 ug/l in October Monitoring well MW04-28-I, proximal to the Intermediate zone pumping well RW07-38-I, also exhibits substantially reduced concentrations of cvocs. Total cvoc concentrations have decreased over two orders of magnitude from 13,250 ug/l (May 2006) prior to pumping to 59.3 ug/l in October 2017 (>99%). Monitoring wells proximal to the Deep zone pumping well also exhibit decreasing trends in cvocs under pumping conditions. Prior to pumping, cvoc concentrations of deep outwash well MW04-30-BR were as high as 14,090 ug/l (October 2006) and have decreased by approximately two orders of magnitude to 179 ug/l in October 2017, a decrease of over 98% from the concentration prior to startup. Total cvoc 7

12 June concentrations in Deep outwash well MW00-43-BR decreased over two orders of magnitude from 895 ug/l prior to the system start up (May 2006) to 6.3 ug/l in October 2016, a >99% decrease. Total cvoc concentrations in bedrock OPD monitoring well MW02-01-OPD, located near RW06-27-BR but with a deeper well screen (within the Shakopee), decreased from 908 ug/l observed under pre-pumping conditions (October 2007) to 20.4 ug/l in October 2017, a 98% decrease. These results from wells within the plume core, the areas of highest concentration, indicate that significant reductions (from 98% to >99%) are occurring, consistent with achieving the system performance goals. A few peripheral wells in the monitoring network have exhibited variable trends in cvoc concentrations: A relatively small zone of contaminated groundwater between the area north of the Roundhouse and the former Waste Reclamation Area is currently monitored by wells MW04-24-T, MW06-01-I, and MW-403D (See Figure 1). This area was not designed for active remediation due to the presence of naturally declining concentrations. For example, monitoring well MW-21A had declined from 435 g/l in 1993 to 83 g/l in October 2012 (an 81% decrease since 1993) and was decommissioned in 2012 (MPCA, 2012). MW04-24-T has maintained a steadily downward trend in concentration (Appendix A). Well MW-403D has exhibited stable cvoc concentrations since system startup. Monitoring well MW06-01-I is part of a three well cluster that also includes a shallower well (MW06-01-T) and a deeper well (MW06-01-BR). Total cvocs have not been detected in the shallower zone in MW06-01-T. Total cvoc concentration trends in the deeper well, MW06-01-BR, are variable, ranging generally between 10 ug/l and 100 ug/l (13.4 g/l in October 2017). In MW06-01-I, cvoc concentrations have exhibited variability under pumping conditions but exhibit a downward trend overall since 2012, with a substantial decrease in 2017 to 47.9 g/l, a 94% reduction. Given the substantial reductions in groundwater concentrations throughout the plume core as a result of pumping, minor variability in concentrations on the fringes of the plume are not significant with respect to the overall reduction achieved in plume mass. 5.0 CONCLUSIONS The overburden groundwater remedial system in the southeastern area of the East Side Shoreham Facility was operated and maintained in accordance with the design objectives in 2017, and, in addition, an approved shutdown/rebound testing program was initiated. Shutdown of four of the five extraction wells commenced in July 2017 with rebound monitoring well sampling indicating no adverse impact of partial shutdown. Groundwater capture at RW07-39-SP remains consistent with that anticipated in design, and 385 pounds of VOCs have been removed from the groundwater since the startup of the system, with 9.0 pounds being removed in Wells within the plume core, monitoring the most contaminated areas prior to operation, exhibit decreases of cvoc concentrations of 98% to 99% since the start of system operation. Extraction wells RW06-27-BR, RW07-38-I, RW06-28-I, and RW07-40-SP continued to exhibit decreases of total cvocs between December 2016 and July Similarly, extraction well RW07-39-SP continues to show decreases of total VOCs from December 2016 to December Semi-annual monitoring of groundwater quality will continue, along with monthly effluent monitoring, during The shutdown monitoring program will continue in 2018 with sampling events in January and May
