1.0 Introduction An Administrative Settlement Agreement and Order on Consent for Removal Action (AOC) was executed for the Block P Mine Complex on June 16, 2011 by the United States Environmental Protection Agency Region 8 (USEPA) and The Doe Run Company [Doe Run] (USEPA, 2011). As part of its response to the AOC, Doe Run submitted a document to USEPA in April 2013 entitled “Post Removal Site Control Plan – REVISED” [PRSC Plan] (Barr, 2013b). The PRSC Plan contributes to meeting the removal action objectives by proposing a scope and frequency of site monitoring activities that will, when implemented, enable Doe Run and USEPA to assess the integrity and effectiveness of removal actions implemented in 2011–2013 through a combination of site inspections and monitoring of revegetation progress and surface water and groundwater quality.

This annual report is the fourth deliverable prepared by Doe Run as part of its implementation of the PRSC Plan. The 2015 annual report was submitted to USEPA in January 2016 (Barr, 2016a).

1.1 Project Background The Block P Mine Complex (the Site) is located in the Barker/Hughesville mining district, approximately 45 miles southeast of Great Falls, Montana (Figure 1). Between 2008 and 2010, Doe Run conducted an Engineering Evaluation/Cost Analysis (EE/CA) for the Site, culminating in the submittal of the final EE/CA to USEPA in March 2010 (Barr, 2010). As stated in the EE/CA, the objective of the Block P Mine Complex removal action was to reduce the threat to public health, welfare, and the environment posed by the release of metals-contaminated water resulting from interaction of water with mine wastes. In order to meet this objective, the selected removal action called for excavation of uncontrolled mine wastes and consolidation of the excavated materials into a repository capped with an engineered geomembrane cover system.

The EE/CA evaluated several potential locations for an engineered repository. The recommended location offered sufficient space, access, and community support for the placement of waste rock from not only Doe Run’s mining sites, but potentially also from the additional “orphan” waste sites currently located within the Galena Creek watershed. Upon approval of the EE/CA, Doe Run began the process of acquiring selected parcels of property needed to construct the repository. Doe Run’s acquisition of these parcels allows state and federal agencies to potentially consolidate the additional “orphan” wastes into a single, common repository for the Barker-Hughesville NPL site. A schedule for consolidation of the additional “orphan” wastes into the repository constructed by Doe Run has yet to be finalized.

1.2 Summary of Removal Actions In accordance with the AOC, removal action activities began at the Site in 2011 with the preparation of the sub-base for an on-site engineered repository and the placement of approximately 140,000 cubic yards of waste rock from the Block P mine dump in the on-site repository. Site work was suspended in late fall 2011 due to winter weather conditions. Removal actions resumed in June 2012 with excavation and transport of approximately 160,000 cubic yards of waste rock from the Block P mine dump, Wright and Edwards mine area, Belt Patent waste rock pile, several miscellaneous waste rock piles, and the Galena

2

Creek streamside area. Following excavation of waste rock from the Galena Creek floodplain, the creek channel was reconstructed and new culverts and protective riprap were installed. An engineered cover was installed on the repository and surface water control features were installed at the repository and in other areas disturbed by earth moving activities. Soil amendments were incorporated as needed and the areas disturbed by the removal action were revegetated in fall 2012.

To complete the removal actions at the Site, approximately 1,500 live willow stakes were installed along the reconstructed sections of Galena Creek in June 2013 as the final element of the removal actions. This work was done in accordance with the revised site restoration and revegetation plan (Barr, 2012a).

Additional details concerning the 2011-2012 removal actions are found in the Removal Action Final Report (Barr, 2013a).

1.3 Objectives of the PRSC Program As stated in the PRSC Plan, the objectives of the PRSC Program are to:

1. Maintain integrity of the work performed during the removal action, including:

• Containment of mine waste in the repository;

• Maintenance of the repository cover system to prevent migration of hazardous substances;

• Reclamation and revegetation of areas of disturbance at the former Block P, Wright, Edwards, and Belt Patent waste dump sites; and

• Maintenance of the reconstructed sections of the Galena Creek channel so that they are fully stabilized and functioning effectively for anticipated flow rates.

2. Monitor the effect of the removal actions on groundwater and surface water quality at or adjacent to the Site; and

3. Collect appropriate data needed for USEPA to prepare a five-year site review report.

It is anticipated that these objectives can be achieved by conducting site inspections and periodic water quality sampling between now and the end of 2017. The proposed monitoring activities may be revised in the field to accommodate actual site conditions. The inspection monitoring and frequency will also be evaluated following the initial five-year period.

Given the number of uncontrolled mine sites that remain in the Galena Creek watershed, it is not expected that the removal actions taken at the Site as part of this project will, by themselves, result in both groundwater and surface water quality that achieve Montana DEQ-7 standards (Montana DEQ, 2012). Doe Run does, however, expect that improvements in both media will be observable by the end of the first five years of the PRSC program.

2.0 2016 Site Inspection Activities Four PRSC site visits were made in 2016. The intent of the PRSC site visits was to photodocument site conditions, look for evidence and/or damage from trespassing or uncontrolled erosion, and visually assess the condition of the private access roads leading to the repository, the repository integrity, and the stability of the reconstructed channel of Galena Creek. Staff from Barr Engineering Co. (Barr) and TD&H Engineering (TD&H), working as a subconsultant to Barr, completed site visits during the following weeks of 2016:

• June 6 • July 4 • August 8 • September 12 (Visit by Doe Run and EPA representatives only) • October 10

The following paragraphs discuss the conditions observed during site inspections. Inspection forms were prepared as part of the June, July, August, and October site visits, and are included as Appendix A1. Complete sets of photographs from the routine photograph locations were taken during each inspection from the locations identified on Figures A-1, A-2 and A-3. The photographs are provided on CD as Appendix A2. The remainder of this section generally reflects the order of actions as presented in Section 3.0 of the PRSC Plan (Barr, 2013b).

2.1 Site Control The gate at the bottom of the private access road leading up to the repository remained closed, but not locked, throughout the year. The service door on the storage shed at the Site was vandalized again in 2016. The door was repaired by covering with plywood in 2015. The plywood was removed, the door was broken down, and a hole was punctured in the back wall of the building in late summer 2016. The building was barricaded to protect from the winter elements once again in October 2016.

2.2 Access Roads Site access via the county road, and the road leading to the repository was possible for four-wheel drive vehicles during each of the 2016 site visits. Some areas of significant erosion were noted in August 2016 due to a large rain storm which made the road rough, but still passable. In October, several downed trees blocked the road to the repository, however they were removed by hand to maintain access.

2.3 Repository Inspection The repository cover appeared to be stable and in good condition during each of the site visits and no evidence of slope stability problems was observed. Two areas of ponding water were observed on the top of the repository. The ponding was likely due to the melting of several inches of snow that fell in the days prior. The ponded water was not very deep, however the areas will be monitored in 2017 to observe for additional settling. No areas of surface erosion were noted on the repository slope. An erosion rill

4

observed in 2015 was monitored in 2016, however conditions had improved. The ground surface was saturated in the seep area during all of the site inspections in 2016. No significant flow was observed from the culvert/ draintile outlet near the seep area. Some accumulated sediment was observed at the culvert outlets near the seep area and the culvert which directs flow to the southwest of the repository, however no flow has been observed to date. Erosion was observed on the perimeter road along the east side of the repository. The erosional areas did not prevent travel by vehicle around the top of the repository, however conditions did get worse following summer rain as noted in the August and October inspections. All other erosion control management features installed on or near the repository were observed to be in good condition and to be functioning appropriately throughout the year. The temporary groundwater monitoring wells TW-01 and TW-02 located on the west side of the repository are protected by orange construction fence.

2.4 Galena Creek Channel Stability Short term integrity inspections of the reconstructed channel of Galena Creek were conducted during the June 6th and October 10th visits in 2016. The reach of Galena Creek near photo point BB-4P received loading of some sediment from adjacent erosion of the Block P Mine Slope. The conditions were noted in October following summer runoff events. Sediment has washed in between the boulders forming the channel edge along the mine slope. The pool in the creek channel looks to have received additional sediment load however the flow pattern of the stream did not appear to be effected. Some grassy vegetation can now be seen growing in that particular pool of the stream. No other additional bank or toe failures were identified beyond what was noted near BB-4P. The upstream and downstream culverts were observed in good condition. The meander bend cutoff or avulsion first identified in 2013 near station 6+00 did not appear to have changed in 2016.

2.5 Erosion Control Erosion was noted at multiple areas across the site in 2016. The majority of the erosion was observed following a heavy rain event in early August. The site was visited by EPA, and by Doe Run representatives immediately following the storm, and again in September to discuss plans to control the erosion and required maintenance. The following erosion control items were identified during site inspections:

• Erosion of the Block P Mine slope has occurred on the south end of the restored area. This area (captured from photo point BB-4P) is the steepest portion of the slope. Vegetation has been slow to establish in this area, a second hydroseeding effort was made in 2014, however vegetation is still sparse and a bedrock outcrop is starting to emerge. Erosion rills have started to form starting about 2/3 of the way up the slope. Runoff is concentrated due to the shape of the hillside, and has caused sedimentation at the toe of the slope adjacent to the restored Galena Creek channel. Sediment has overtopped the straw bale barrier and has been deposited in the creek. The area of concentrated runoff and sedimentation is approximately 60 feet in length next to the creek. A string of straw waddles is installed on a small bench on the upper portion of the slope as a Best Management Practice (BMP), however most of the erosion rills have developed downhill of this BMP.

5

• Erosion rills have developed in the access road in three specific areas. Similar observations have been made in recent inspections, however conditions have gotten worse in 2016. Along the upper portion of the Block P slope erosion rills have developed parallel with the road as flow is conveyed along the road toward the site access gate. Erosion was also noted along the access road, captured from photo point UA-5P. An approximately 2 foot wide, and 1 to 2 foot deep rill has formed where flow is concentrated and drains to the valley below on the inside bend of the road. The other area of concern is on the southeast side of the repository. Runoff from the perimeter road has caused erosion of the driving surface and hillside captured in photo point R-14P.

• Sediment has deposited near the site access gate within the riprap apron and to the top of the strawbale outlet structure in the drainage pathway to the creek channel. Additional straw bales have been added to this area.

• The straw bale and straw waddle check dams in the base of Dream Gulch (captured in photo point WE-7P and 9P) have deteriorated in Dream Gulch. Erosion appears limited to the concentrated flowpath in the base of the gulch, as vegetation continues to grow on the hillsides. Fresh cut timber has been placed in this area as well.

• Portions of the straw bale barrier at the base of the Block P Mine slope have naturally degraded over time. Additional straw bales have been added to reinforce the barrier to surface runoff.

The actions taken to correct, repair, and/or mitigate the deficient site conditions noted during the 2016 site inspections are described in the following section. Little to no erosion issues were identified in the other areas of the site in 2016. The majority of the Block P Mine Slope, Galena Creek Corridor, Unknown Adit, Upper Wright Mine, and Repository areas remained stable, and BMP’s are in place and functional.

3.0 Site Maintenance Activities This section discusses the maintenance activities completed by Doe Run in response to issues identified during the 2016 PRSC site inspections. A majority of maintenance and repair work was completed on behalf of Doe Run by personnel from Shumaker Trucking. Tree planting was completed by representatives from Barr, TD&H, EPA, USFS, and MTDEQ. Discussion of site maintenance activities is summarized below. Maintenance activities undertaken at the Site in 2016 were documented on the PRSC inspection forms provided in Appendix A-1.

3.1 Site Control Minor repairs were necessary on the storage shed to prevent snow from accumulating in the building over the winter. The building has been broken into several times, and is currently not secured to keep out tresspassers. The building is not owned by Doe Run; however, it has been used to store incidental sampling/monitoring supplies prior to the vandalism. No items of significant value are stored at the site any longer. The wooden structure at the entrance to the Gray Eagle Adit has also been broken into. Plywood was placed on top of the portal in 2016 to cover up some open space where timbers were broken through. No maintenance or repairs to the access road gate were required in 2016. The gate remains chained shut, but the gate is not locked.

3.2 Private Access Road Erosion on the access road has developed over 2014, 2015 and 2016. The road remained trafficable by a four-wheel drive vehicle during the 2016 season; however, re-grading in spring 2017 is recommended to improve conditions and help minimize concentrated runoff that has contributed to the few isolated erosional features noted.

3.3 Repository Engineered Cover System A visual inspection of the repository surface indicated that the thickness of soil cover and emerging vegetation were sufficient in protecting the underlying geomembrane cover, and no significant maintenance or repairs were required to maintain the integrity of the engineered cover system in 2016.

3.4 Galena Creek Channel and Riparian Area Maintenance completed in the Galena Creek channel and riparian area in 2016 consisted of addition of straw bales. A supplemental line of bales was installed in September 2016 along the base of the Block P slope at the edge of the riparian area. The bales were added in the upper approximately 500 feet of the riparian area corridor.

Additional work is planned to mitigate the sedimentation issue near photo point BB-4P. Doe Run intends to install large boulders to create a buttress at the base of the Block P Slope/ edge of Galena Creek where surface runoff is concentrated. This work was discussed with EPA during a site visit during the week of September 12th, 2016. The work has been postponed until 2017 due to winter conditions.

7

3.5 Erosion Control BMPs As described in earlier sections of this report, the 2016 PRSC site inspections revealed the need to repair, replace, and/or enhance several erosion control BMPs at the Site. Maintenance activities undertaken related to the BMPs are summarized below:

• Addition of straw bales along the Galena Creek corridor

• Addition of fresh cut timber to the slopes and across the intermittent flowpath in Dream Gulch

• A line of boulders/ buttress is planned to be installed adjacent to Galena Creek to prevent sedimentation.

4.0 Revegetation and Stream Channel Monitoring This section of the annual report describes revegetation monitoring efforts completed in 2016 in support of the PRSC plan.

4.1 Revegetation Overview The Site Restoration/Revegetation Plan established four revegetation units at the Site: the Galena Creek riparian area, the excavated slopes, the repository cover area, and the restored haul roads (Barr, 2012a). Vegetation sampling transects, photo points, and reference sites for each revegetation unit were selected as part of the September 2013 site visit.

The 2016 growing season marked the fourth growing season following initial revegetation efforts. A vegetation monitoring event was completed in the 2014/2015 seasons along the established transects. No formal revegetation monitoring was completed to quantify the various parameters (i.e. total percent vegetation, percent bare soil cover, etc.) along the transects in 2016. Based on general visual observations of the site, vegetation cover continued to improve throughout 2016. A formal monitoring event is planned for the 2017 growing season.

4.2 2016 Tree Planting At the request of USEPA, Doe Run purchased tree saplings and provided assistance for planting in the spring of 2016 according to the April 8, 2016 memorandum (Barr, 2016b). Planting labor was provided by USEPA, MTDEQ, USFS, and USFWS. A total of 550 tree saplings were planted (10 cubic inch plugs). 250 lodgepole pine (Pinus contorta) and 300 douglas fir (Pseudotsuga menziesii) were planted.

The objectives of the tree planting were 1) to provide added long term stability to loose soil near the top edges of the excavated slopes, and 2) to accelerate the re-establishment of woody vegetation in these areas. Creating the additional vegetative buffer will also reduce the potential for erosion caused by surface water runoff that flows down the reclaimed slopes. Planting efforts were focused along the upper edges of the Block P and the Wright/Edwards slopes. Trees were also planted along the base of Dream Gulch.

Conditions were hot and dry during planting on June 7th. The trees were watered by spraying from a water truck on the access road on June 9th, and again in early July. The weather patterns towards the end of July, into August, and September turned more mild and wet than average, therefore additional tree watering efforts were not pursued.

4.3 Anticipated Future Revegetation Monitoring Per the PRSC Plan, detailed vegetation monitoring will next take place in late summer/early fall of 2017, which represents the fifth growing season. Revegetation performance will again be evaluated after 2017 by comparing reference site vegetation cover to revegetation unit site cover at the completion of the five-year monitoring period.

9

For each revegetation unit, the following vegetation data and information will be collected during future monitoring visits:

• Total percent vegetation cover (two years out of the five-year monitoring period)

• Percent vegetation cover by tree, shrub and forb/grass strata (two years out of the five-year monitoring period)

• Percent bare soil cover (two years out of the five-year monitoring period)

• Tree heights and shrub widths (two years out of the five-year monitoring period, excluding Repository Cover area)

• Live staking percent survival (two years out of the five-year monitoring period)

• List of species present (two years out of the five-year monitoring period)

• Presence of invasive/noxious species (years two through five of monitoring period)

• Mapping of areas of uncontrolled erosion (years two through five of monitoring period)

• General site conditions and viability (years two through five of monitoring period)

4.4 Stream Channel Monitoring A stream channel geometry and morphology assessment was conducted in 2015 to identify potential issues with Galena Creek (Barr, 2016a). The longitudinal profile of Galena Creek changed very little from as-built conditions. Some pools were poorly developed and some jump heights were identified as being restrictive to trout passage. No other impediments to fish passage were identified. In 2016 the Galena Creek channel inspections consisted of an integrity inspection as documented in the PRSC Inspection Documentation (Appendix A).

The Galena Creek channel remained very similar in 2016 as observed in previous years. The only significant change identified was in the area of sediment deposition near photo point BB-4P. As discussed in Section 2.4, the reach of Galena Creek near photo point BB-4P received loading of some sediment from adjacent erosion of the Block P Mine Slope. The conditions were noted in October following summer runoff events. Sediment has washed in between the boulders forming the channel edge along the mine slope. The pool in the creek channel looks to have received additional sediment load however the flow pattern of the stream did not appear to be effected. Some grassy vegetation can now be seen growing in that particular pool of the stream. No other additional bank or toe failures were identified beyond what was noted near BB-4P. The upstream and downstream culverts were observed in good condition. The meander bend cutoff or avulsion first identified in 2013 near station 6+00 did not appear to have changed in 2016.

5.0 Surface Water Monitoring This section of the annual report describes the surface water monitoring conducted in 2016 as Doe Run continues to assess the effects of the removal actions on surface water quality at the Site.

5.1 Background Doe Run has conducted periodic surface water monitoring near the Site since 1996, including the Grey Eagle adit (ADIT-GE-1) and the Block P adit (ADIT-BB-1). An upwelling seep (SW-BB-1) located near the base of the slope below the Block P adit was first encountered in 2011 during excavation of waste rock along Galena Creek. The volume of flow from both the upwelling seep and the Block P adit decreased to essentially zero in 2012 following excavation of additional waste rock along Galena Creek. A new location of (apparent) mine water expression was subsequently observed and identified as SW-BB-2. This new flow has been sampled each year since 2013. It appears to be hydraulically connected in some way to both the former upwelling seep that was monitored at SW-BB-1 and to ADIT-BB-1.

Dream Gulch is a natural drainage feature that is a tributary to Silver Creek, which itself discharges to Galena Creek downstream of the former Belt Patent streamside waste pile. The gulch originates downslope of monitoring well MW-27 and runs downhill through both the Wright and Edwards mine parcels before joining Silver Creek just upstream of the location of the inactive Sinclair Mine (which is not the responsibility of Doe Run). Flow in Dream Gulch is typically seasonal and/or intermittent. Surface water monitoring location SW-WR-1 is located at the headwaters of Dream Gulch. Surface water monitoring location SW-WR-2 is also located in Dream Gulch, below the most downgradient extent of the former Wright/Edwards waste rock piles and upgradient of its confluence with Silver Creek.

Surface water sampling locations SC-SS-1 and SC-SS-2 are located on Silver Creek, immediately upstream and downstream, respectively, of the mouth of Dream Gulch.

5.2 Monitoring Activities The PRSC Plan divides surface water monitoring activities into spring and fall monitoring events. Spring and fall sampling is intended to represent the high and low flow conditions, respectively. Surface water monitoring included the collection of both field data and samples for laboratory analysis. Surface water sample locations are displayed on Figures 3, 4 and 5. Surface water monitoring frequency and parameters are shown in Table 2. Analytical methods for each of the proposed parameters are presented in the project QAPP (Barr, 2012b).

5.2.1 Spring 2016 Monitoring Activities Spring 2016 surface water monitoring was conducted during the week of June 6th by Barr. All samples were collected and analyzed as described in Table 1, with the exception of two locations: SW-WR-1 and ADIT-BB-1. Each were not flowing at the time of the spring 2016 monitoring event. ADIT-BB-1 has not been observed flowing since the completion of the removal actions in 2012. Analytical results for

11

sampling locations along Dream Gulch and Galena Creek are presented in Tables 3 and 4, respectively. Field log data sheets and the laboratory report are provided in Appendix B.

5.2.2 Fall 2016 Monitoring Activities The fall 2016 surface water monitoring was conducted during the week of October 10th by Barr. All surface water samples were collected and analyzed as described in Table 2. Analytical results from fall sampling are presented alongside those from the spring samples for their respective locations in Tables 3 and 4. Field log data sheets and the laboratory report are provided in Appendix B.

5.3 Surface Water Quality Trend Analysis The surface water quality data collected from both Dream Gulch and Galena Creek since completion of the removal actions suggest that site conditions are showing signs of improvement. Most notably, total and dissolved metals concentrations appear to be trending downward at both SW-WR-02 and GC-SS-2. Figure 6 plots the concentrations of selected parameters over time for GC-SS-2.

12

6.0 Groundwater Monitoring This section describes the groundwater monitoring activities conducted in 2016 as a part of the PRSC program. The intent of the PRSC groundwater monitoring effort is to evaluate the effect of the removal actions on groundwater quality at the Site. The locations of the monitoring wells are shown on Figures 3, 4, and 5.

6.1 Background Monitoring wells HMW-06, MW-15, MW-17, and MW-20 were established in the vicinity of the Site prior to the 2011-2012 removal actions. Three permanent monitoring wells (MW-25, MW-26, and MW-27) and two temporary wells (TW-1 and TW-2) make up the monitoring well network around the perimeter of the repository. These wells were installed during removal actions in 2012. The intention of the permanent wells is to help evaluate long-term groundwater conditions near the repository. The temporary wells were intended to help evaluate groundwater conditions immediately adjacent to the surface seep.

Water level elevation data and sampling results from prior to PRSC monitoring are provided in the Removal Action Final Report (Barr, 2013a). Water level elevation data suggest that the seep feature is an expression of native shallow groundwater that is primarily present at the interface of surficial soils with competent bedrock. A drain tile was installed near the surface seep to minimize the potential for groundwater to contact the toe of the repository. Performance of the drain tile has been inspected as part of routine site inspections since 2013.

6.2 Monitoring Activities The PRSC Plan divides groundwater monitoring activities into spring and fall monitoring events. Spring and fall sampling is intended to represent the high and low water level conditions, respectively. Groundwater monitoring included the collection of both field data and samples for laboratory analysis. Groundwater monitoring frequency and parameters are shown in Table 3. Analytical methods for each of the proposed parameters are presented in the project QAPP (Barr, 2012b).

6.2.1 Spring 2016 Monitoring Activities The spring 2016 groundwater monitoring was conducted during the week of June 6th by Barr. All samples were collected and analyzed as described in Table 2, with the exception of MW-25 and MW-26. Both wells contained insufficient water volume to be sampled. Field log data sheets are provided in Appendix B. The groundwater monitoring analytical results are presented in Tables 5 and 6.

6.2.2 Fall 2016 Monitoring Activities The fall 2016 groundwater monitoring was conducted during the week of October 10th by Barr. All groundwater samples were collected and analyzed as described in Table 2, with the exception of MW-20, MW-25, and MW-26. MW-25 and MW-26 were dry in the fall. MW-20 was not sampled due to a malfunctioning purging/sampling pump. Analytical results from the fall sampling event are presented

13

alongside those from the spring samples for their respective locations in Tables 5 and 6. The laboratory report for the fall samples is provided in Appendix B.

6.3 Groundwater Quality Trend Analysis As stated in the PRSC Plan, one objective of the PRSC program is to monitor the effect of the removal actions on groundwater quality at or adjacent to the Site. In the case of monitoring well MW-27, this location was selected to assess groundwater quality downgradient of the repository and provide a means of observing whether the presence of the repository itself led to any changes in groundwater conditions at the upper end of Dream Gulch. As shown in Table 6 and on Figure 7, the groundwater quality at MW-27 appears to be stable, especially when accounting for the elevated concentrations observed in the extremely turbid samples collected immediately after the well was constructed in the spring of 2012.

Monitoring wells HMW-06 and MW-17 are located adjacent to Galena Creek, directly downgradient of the Block P mine workings and former Block P mine dump. MW-17 is screened in the shallow unconsolidated unit, and HMW-06 is completed slightly deeper, in the bedrock layer. As shown in Table 5 and on Figures 8 and 9, the concentrations of dissolved metals at both locations appear to be trending downward since completion of the removal actions.

7.0 Analytical Data Quality Control Review A quality assurance and quality control review was conducted to assess the integrity of the sampling and analytical procedures performed on the groundwater, adit, and surface water samples at the Site during 2016. Field sampling procedures were examined utilizing field blank and masked (field) duplicate sample analysis. Laboratory procedures were evaluated by examining technical holding times, duplicate samples, precision and accuracy data, method blank samples, and data package completeness. The data met the data project requirements and are deemed acceptable as qualified for the purposes of this project. Noteworthy items are included in the following paragraphs.

Field blank samples are used to assess the existence and magnitude of contamination introduced in the field at the Block P Mine Complex Site. Two field blank samples were collected and analyzed during the June and October 2016 sampling events. The June field blank sample had a hardness detection (2.0 mg/L) which was greater than the laboratory reporting limit; however, no site data was qualified because the groundwater and surface water samples were greater than five times the field blank sample concentration. The field blank from the October sampling event had no detections of target analytes above the laboratory reporting limit.

In one case, the field duplicate sample relative percent difference (RPD) was above the 30 percent criteria listed in the quality assurance project plan. The dissolved iron result for surface water sample GC-SS-1 and its corresponding field duplicate sample were “*” qualified and should be considered estimated.

There were several instances where the dissolved metals concentrations exceeded the total metals concentrations for both monitoring events. No data were qualified because the differences were attributed to normal analytical variability.

8.0 Conclusions and Recommendations This section of the annual report discusses the results of PRSC monitoring and maintenance activities undertaken at the Site in 2016 and makes recommendations for 2017.

8.1 Site Inspection and Maintenance The results of the 2016 site inspection and maintenance activities demonstrate that the erosion control efforts have helped to stabilize the majority of critical areas of the Site throughout 2016. Erosion in multiple areas of the site did occur requiring some maintenance and improvement of control BMPs. Activities completed included:

• Addition of straw bales along Galena Creek • Dropping fresh timber in Dream Gulch

Other activities planned for early 2017 include:

• Grading the access road from the gate near the site entrance to the perimeter road around the repository

• Installing boulders to create a buttress at the toe of the Block P slope where sedimentation has impacted the creek channel.

• Securing the storage shed and adit entrance structures on site to dissuade trespassing to these potentially dangerous areas.

8.2 Revegetation Monitoring The baseline revegetation monitoring event was conducted in 2013 and provides a comparison point for the more extensive monitoring performed in Year 2 (2014–2015) of the PRSC program, as well as for the revegetation monitoring to be performed again in Year 5 (2017). Observations made during 2016 and the years prior suggest that vegetation in most revegetation units has gotten off to a good start. Progress toward the objectives established by the applicable reference sites will be evaluated during the 2017 growing season.

8.3 Surface Water Monitoring The results of 2016 surface water monitoring at the Site (both Dream Gulch and Galena Creek) are consistent with the data collected from 2013 through 2015. Concentrations of total and dissolved metals observed in the surface water that exits Dream Gulch appear to be on a declining trend. Data for downstream Galena Creek monitoring station GC-SS-2 continues to also demonstrate an improving trend in water quality. As expected, the quality of water discharging from the Grey Eagle adit remains fairly stable.

16

8.4 Groundwater Monitoring The 2016 groundwater monitoring data are stable and/or improved compared to 2013 through 2015. Near Galena Creek, the data from upgradient well MW-15 appears to be generally tracking within historical ranges, while the data collected in 2016 from streamside wells MW-17 and HMW-06 demonstrate continued improvement compared to pre-removal action data. The groundwater quality at monitoring well MW-27 (immediately downgradient of the repository), is consistent with the data collected in 2013 through 2015.

8.5 Recommendations Except as noted below, Doe Run recommends that 2017 monitoring and maintenance activities at the Site be conducted in accordance with the previously submitted PRSC Plan.

A similar approach to site inspection activities will be taken in 2017 with the intent of identifying potential problems associated with runoff early in the season to minimize the potential for uncontrolled soil erosion at the Site. Doe Run will work with their local earthwork contractor to complete the site maintenance tasks which were unable to be completed in 2016 due to winter weather conditions.

Doe Run completed planting of conifer saplings in 2016. Some saplings appeared to survive through the hot and dry months of the 2016 summer. No additional watering of the saplings is planned for 2017. If the survival rate of the trees appears to be low, for example below 50%, discussion will take place with the Agencies to determine if additional tree plantings are necessary.

If, after the spring 2017 site monitoring event (tentatively scheduled for May or early June), Doe Run believes that additional modifications to the 2017 monitoring program are warranted, it will contact USEPA for further discussion.

Inorganic Data Qualifiers

* The result is an outlier. See case narrative.

# The control limit criteria is not applicable. See case narrative.

B The analyte was found in the associated method blank at a level that is significant relative to the sample result as defined by the DOD or NELAC standards.

E The result is an estimate amount because the value exceeded the instrument calibration range.

J The result is an estimated value.

U The analyte was analyzed for, but was not detected ("Non-detect") at or above the MRL/MDL. DOD-QSM 4.2 definition : Analyte was not detected and is reported as less than the LOD or as defined by the project. The detection limit is adjusted for dilution.

i The MRL/MDL or LOQ/LOD is elevated due to a matrix interference.

X See case narrative.

Q See case narrative. One or more quality control criteria was outside the limits.

H The holding time for this test is immediately following sample collection. The samples were analyzed as soon as possible afterreceipt by the laboratory.

Metals Data Qualifiers



E The percent difference for the serial dilution was greater than 10%, indicating a possible matrix interference in the sample.

M The duplicate injection precision was not met.

N The Matrix Spike sample recovery is not within control limits. See case narrative.

S The reported value was determined by the Method of Standard Additions (MSA).


W The post-digestion spike for furnace AA analysis is out of control limits, while sample absorbance is less than 50% of spike absorbance.



+ The correlation coefficient for the MSA is less than 0.995.


Organic Data Qualifiers



A A tentatively identified compound, a suspected aldol-condensation product.


C The analyte was qualitatively confirmed using GC/MS techniques, pattern recognition, or by comparing to historical data.

D The reported result is from a dilution.

E The result is an estimated value.


N The result is presumptive. The analyte was tentatively identified, but a confirmation analysis was not performed.

PThe GC or HPLC confirmation criteria was exceeded. The relative percent difference is greater than 40% between the two analytical results.


i The MRL/MDL or LOQ/LOD is elevated due to a chromatographic interference.



Additional Petroleum Hydrocarbon Specific Qualifiers

F The chromatographic fingerprint of the sample matches the elution pattern of the calibration standard.

L The chromatographic fingerprint of the sample resembles a petroleum product, but the elution pattern indicates the presence of a greater amount of lighter molecular weight constituents than the calibration standard.

H The chromatographic fingerprint of the sample resembles a petroleum product, but the elution pattern indicates the presence of a greater amount of heavier molecular weight constituents than the calibration standard.

O The chromatographic fingerprint of the sample resembles an oil, but does not match the calibration standard.

Y The chromatographic fingerprint of the sample resembles a petroleum product eluting in approximately the correct carbon range, but the elution pattern does not match the calibration standard.

Z The chromatographic fingerprint does not resemble a petroleum product.

ALS ENVIRONMENTAL Client: Barr Engineering Company Service Request No.: K1606194 Project: Block P Mine Complex / 26070005 Date Received: 6/8/2016 Sample Matrix: Water

Case Narrative All analyses were performed consistent with the quality assurance program of ALS Environmental. This report contains analytical results for samples designated for Tier II data deliverables. When appropriate to the method, method blank results have been reported with each analytical test. Additional quality control analyses reported herein include: Laboratory Duplicate (DUP), Matrix Spike (MS), Matrix/Duplicate Matrix Spike (MS/DMS), Laboratory Control Sample (LCS), and Laboratory/Duplicate Laboratory Control Sample (LCS/DLCS). Sample Receipt Ten water samples were received for analysis at ALS Environmental on 6/8/2016. The samples were received in good condition and consistent with the accompanying chain of custody form. The samples were stored in a refrigerator at 4ºC upon receipt at the laboratory. General Chemistry Parameters No anomalies associated with the analysis of these samples were observed. Total and Dissolved Metals Matrix Spike Recovery Exceptions: The control criteria for matrix spike recovery of Aluminum, Copper, Iron, and Manganese for sample GC-SS-2 were not applicable. The analyte concentration in the sample was significantly higher than the added spike concentration, preventing accurate evaluation of the spike recovery. No other anomalies associated with the analysis of these samples were observed.

Client: Barr Engineering Company Service Request No.: K1612525 Project: Doe Run Block P Mine/ 2607005.07 2016 400 Date Received: 10/14/16Sample Matrix: Ground Water, Surface Water, Water

Case Narrative

All analyses were performed consistent with the quality assurance program of ALS Environmental. This report contains analytical results for samples designated for Tier II data deliverables. When appropriate to the method, method blank results have been reported with each analytical test. Additional quality control analyses reported herein include: Laboratory Duplicate (DUP), Matrix Spike (MS), and Matrix/Duplicate Matrix Spike (MS/DMS).

Sample Receipt

Fourteen samples were received for analysis at ALS Environmental on 10/14/16. The samples were received in good condition and consistent with the accompanying chain of custody form. The samples were stored in a refrigerator at 4ºC upon receipt at the laboratory.

General Chemistry Parameters

Sulfate by EPA Method 300.0: The matrix spike recovery criteria of Sulfate for sample Batch QC was not applicable. The analyte concentration in the sample was significantly higher than the added spike concentration, preventing accurate evaluation of the spike recovery. Recovery in the Laboratory Control Sample (LCS) was acceptable, which indicates the analytical batch was in control. No further corrective action was appropriate.

No other anomalies associated with the analysis of these samples were observed.

Total and Dissolved Metals

Matrix Spike Recovery Exceptions: The control criteria for matrix spike recovery of Calcium and Aluminum for the Batch QC sample were not applicable. The analyzed concentration in the sample was significantly higher than the added spike concentration, preventing accurate evaluation of the spike recovery.

The matrix spike recovery of Aluminum for the Batch QC sample was outside control criteria. However, the analyzed concentration in this sample was significantly higher than the added spike concentration, preventing accurate evaluation of the spike recovery. Recovery in the Laboratory Control Sample (LCS) was acceptable, which indicates the analytical batch was in control. No further corrective action was appropriate.

No other anomalies associated with the analysis of these samples were observed.
