RE: 2024 Eureka Mills Annual Site Inspection Report

Dear Mr. Nichalson:

Enclosed with this letter is the Utah Department of Environmental Quality, Division of
Environmental Response and Remediation's (DERR) 2024 Annual Site Inspection Report for the
Eureka Mills Superfund Site. The report includes a summary report, photographic log, and
inspection checklists for the mine waste piles, Open Cell repository, drainages, sedimentation
ponds, and access roads as defined in the Operation & Maintenance Manual, Eureka Mills
Superfund Site, Eureka City, Utah, July 31, 2009. The report also contains a brief summary and
photographic log of the operation and maintenance repair work completed in 2024 under Work
Assignment #13.

The Annual Site Inspection was conducted on October 14, 15, and 17, 2024, by Craig
Barnitz, Project Manager for the DERR.

Two sinkholes were observed in the area of the Bullion Beck Mill Site and Gemini Mine
Waste Pile. The DERR discussed the sinkholes with Steve Fluke, Section Manager for the Utah
Division of Oil, Gas, and Mining Abandoned Mine Reclamation Program (AMRP). Based on the
discussion with Mr. Fluke, the repairs to the sinkholes will be undertaken by the AMRP during the
2025 work season.

The DERR also noted several collapsed buildings at the site. The collapsed buildings may
present an exposure pathway for contaminated soils beneath the foundations. Other than the noted
sinkholes and collapsed buildings, the remedial action structures were observed to be intact and
protective of human health and the environment.

Other issues, including soil management within the Open Cell and clearing vegetation from
the Eureka Gulch, will be addressed with the city of Eureka.

If you have any questions, please contact me at [phone].

Sincerely,

EUREKA MILLS
ANNUAL SITE INSPECTION SUMMARY REPORT
October 14-17, 2024

SUMMARY:
The Annual Site Inspection was conducted on October 14, 15 and 17, 2024, by Craig Barnitz,
Project Manager for the Utah Department of Environmental Quality, Division of Environmental
Response and Remediation (DERR). The inspection was conducted in accordance with the
Operation & Maintenance Manual, Eureka Mills Superfund Site, Eureka City, Utah, July 31,
2009 (O&M Manual). The manual provides inspection checklists for all Remedial Action
Structures (RASs), including: capped mine waste piles, drainages, sediment ponds and
haul/access roads. The appendices included in this inspection are as follows:
• Appendix A: Photo-Log
• Appendix B: Remedial Action Structure Checklists
• Appendix C: O&M Maintenance and Repair Work Assignment #13 Summary and
Photo-Log
The DERR arrived in the city of Eureka on Monday, October 14, 2024 at 10:39 AM. The
temperature was approximately 62○Fahrenheit (○F) on arrival with an anticipated high of 73○F,
and the observed weather was clear skies and sunny. Weather conditions on Tuesday, October 15
were clear skies, sunny with a slight breeze. The temperature upon arrival 60○F and an
anticipated high of 74○F. Weather conditions on Thursday, October 17 were overcast with rain
with the temperature upon arrival at 46○F and an anticipated high of 53○F.

The inspection occurred concurrently with O&M repair activities conducted by AECOM and
their subcontractor, 5seventeen Company, under Work Assignment #13. Prior to the inspection
on Monday October 14, DERR met with Lindsay Anderson (AECOM) to observe work to
remove the burned flooring and repair the cap at the Chief Mine No. 1. DERR made periodic
visits with the contractors to receive updates on the O&M repairs. DERR also met with Corbin
Jensen (Ivanhoe Electric) on Monday, October 14 to discuss access to the Bullion Beck and
Gemini Mine sites.
KEY FINDINGS
Priority Issues for 2025:
1. Sinkholes: Two sinkholes were observed near the Bullion Beck and Gemini Mines.
Following the inspection, DERR coordinated with Utah Division of Oil, Gas, and Mining
2

Abandoned Mine Reclamation Program (AMRP), which will conduct repairs during the
2025 reclamation season.
2. Collapsed Buildings: Several collapsed buildings were noted at the site. The first one
was located at the east side of Chief Mine No. 1 Mine Waste Pile near the fence line;
another is a former blacksmith shop along the south end of the Eagle Blue Bell Mine
Waste Pile; and lastly, a smaller shed like structure at the north end of the Eagle Blue
Bell Mine Waste Pile. The collapsed buildings partially expose and present an exposure
pathway for contaminated soils beneath the foundations. Discussions between DERR and
EPA on management responsibilities are ongoing.
3. Leaking Drum: A 55-gallon drum containing a petroleum-like substance was found in a
collapsed building at Chief Mine No. 1. The release appears aged and degraded. DERR
will contact the property owner about cleaning up the released oil.

Secondary Observations:
1. Open Cell Debris: Construction debris, including concrete slabs and a steel post, was
observed in the soil piles within the Open Cell. DERR will coordinate with Eureka City
to ensure compliance with disposal protocols and verify grading/compaction
responsibilities.
2. Vegetation Growth: Larger vegetation, including small trees, was observed on the
slopes at the Bullion Beck Mill site, the KC Sedimentation Pond, drainages along the
Chief Mill No. 1 Access Road and the north toe of the Chief Mine No.1 Waste Pile.
Weeds, sagebrush, and small trees, were also observed in the Upper and Lower Eureka
Gulch. The DERR will assess options for removal of the vegetation.
3. Historic Steel Tank: A rusted steel tank (approximately 500-1,000 gallons) was found at
the bottom of the east slope of the Chief Mine No. 2 Waste Pile. The tank does not appear
to affect the armored rock cap, and given the current location (low on the slope), the tank
is not easily accessible. The DERR inspected the tank and determined it was empty and
therefore not at risk for a release. Though stable, continued monitoring and potential
removal are recommended.
4. Knightsville Road Erosion: Juab County identified that the east shoulder of Knightsville
Road was susceptible to washing out during heavy run-off events. DERR will evaluate
adding armor rock under the LOE contract during future planned repairs.

The following is a brief summary of the key points noted during the inspection.

Bullion Beck Mill Site and Mine Waste Pile:
• A 20-foot diameter by 20-foot deep sinkhole was observed north of the west access
gate leading to the Gemini Mine and Bullion Beck Mill sites.
o It was determined the AMRP could repair the sinkhole as part of the 2025
seasonal reclamation work.
• Minor vegetation was observed along the Bullion Beck Mill access road.
• The Bullion Beck Mill access gate was locked and secured.
• Tire tracks were noted in the untreated base course rock cap but no evidence of
trespass was observed. Tire tracks likely result from the property owner’s vehicles.
• Small trees were identified growing on the slopes of the Bullion Beck Mill Site.
3

o DERR should evaluate options for removing larger vegetation from the Mill
Site.
• At the Bullion Beck Mine Waste Pile, damage to the fencing surrounding the head
frame was observed.
o The damage does not appear to affect the protectiveness of the remedy.

Chief Mill No. 1 and Chief No. 1 Mill Tailings Waste Pile:
• Minor vegetation was observed on the armored rock slopes and caps at the Chief No.
1 Mill Tailings Waste Pile and CMT-1 Sedimentation Pond.
• The vegetative cap is largely intact and shows no signs of erosion.
• The ATV path that runs along the north and east sides showed no evidence of recent
use or damage resulting from the use of the trail.
• An animal trail was observed running along the south end of the vegetative cover but
did not appear to affect the protectiveness of the remedy.
• Previously identified exposed geotextile fabric on the southeast side was inspected
and determined to be a fabric webbing to facilitate growth of the vegetative cap.
o No maintenance or repair is required.

Chief Mill Site No. 1:
• The armored rock and vegetative caps both remain intact and show no signs of
displacement.
• Minor amounts of vegetation were also noted along the Reservoir Road at the top of
the waste pile.
• Minor rutting and erosion was observed along the Reservoir Road.
• A small section of geotextile liner was exposed where the vegetative cover meets the
armored rock on the northeast side near the drainage.
o DERR should closely monitor the exposed geotextile liner for further erosion
and consider appropriate repairs to protect the liner.

Chief Mill Site No. 1 Access Road and Drainage Channel:
• Previously noted erosion along the access road was repaired and no additional erosion
was observed.
• Vegetation, including small trees, was observed in the Chief Mill Site No. 1 drainage
channel.
o DERR will evaluate options for the removal of larger vegetation, including
small trees, from the drainage channel.
• Missing fencing, signs and gates to the ATV Path and T Street were also noted during
the inspection.
o The missing fencing, signs and gates do not affect the protectiveness of the
remedy.

Chief Mine No. 1 Waste Pile:
• A historic mining building on the east side of the waste pile had collapsed exposing
the potentially lead-contaminated soils beneath the foundation.
4

o DERR and EPA need to determine responsibility for the removal of collapsed
building and repairs to the cap beneath the foundation.
• A 55-gallon drum within the collapsed structure had leaked an unknown quantity of a
petroleum-like substance to the soils. The release appeared to be old and degraded.
o DERR will attempt to notify the property owner about cleaning up the released
oil.
• Minor amounts of vegetation were noted on the slopes and the untreated base course
top of the mine waste pile.
• A large tree was noted growing at the east end of the north drainage.
o DERR will evaluate options for the removal of the tree from the drainage.

Chief Mine No. 2 Mine Waste Pile and Access Road:
• During previous inspections, significant vegetation was noted in the untreated base
course cap surface of the mine waste pile and along the access road. This vegetation
appeared to have been recently removed by the property owner.
• The gates at the entrance to the access road and around the head frame were locked and
secured.
• Minor erosion rills were observed in the access road.
• The fencing along the south side of the Chief Mine No. 2 headframe was damaged.
Signage was missing from the fencing.
o DERR will make the minor repairs to the fencing around the head frame.
• The rusted steel tank (approximately 500-1,000 gallons) remains on the east slope of
the Chief Mine No. 2 Waste Pile. The DERR inspected the tank and determined it was
empty. The tank does not affect the remedy.
o DERR recommends continued monitoring of the tank and evaluating the
potential for removal from the site.

Eagle Blue Bell Mine Waste Pile:
• The historic blacksmith building at the south end of the site was brought down in an
avalanche during the 2022-2023 winter and a small shed at the north end of the waste
pile had also recently collapsed potentially exposing lead-contaminated soils beneath
the wooden foundations of the two buildings.
o DERR and EPA need to determine responsibility for the removal of the
collapsed buildings and repairs to the cap beneath the foundation.
• Minor amounts of vegetation were observed on the untreated base course cap surface
and the armored rock slopes.
• The water bars located on the east side and the west side of the waste pile are in good
condition with minor erosion rills and vehicle tracks observed on the west side.

Eagle Blue Bell Drainage Channel:
• No erosion was noted in the Eagle Blue Bell drainage channel or along the haul road
where it crosses the drainage.
• Minor vegetative growth was noted in the channel and around inlets and outlets at the
culverts, but did not appear to impede the flow of water in the system.
o No repairs or maintenance are required.
5

Eureka City Yard:
• Vegetation and general debris were observed along the floors and embankments of the
Lower Eureka Gulch at the south end of Eureka City Yard.
o DERR will discuss with the city of Eureka the need to clear vegetation from the
gulch.
• The STOP sign and fencing were missing at the exit to the Eureka City Yard.
Recommend continued monitoring of the vegetation and removal of debris from inside
the drainage. The missing sign and fencing does not affect the remedy.
o DERR will consult with Eureka about the need for replacement of the STOP sign.

Eureka Hill Mine Waste Pile:
• The inspection showed minor weeds growing on the surface of the mine waste pile and
within the drainage paths.
• The armor rock slopes were in good condition and showed no evidence of erosion.
Vehicle tracks were observed on both the east and west untreated base course caps, but
no damage was noted.
• Gates and fencing around the headframe and mine shaft were noted as locked and in
good condition.
o No repairs or maintenance are required.

Gardner Canyon (GC) GC-1, GC-2 and GC-3 Sedimentation Ponds:
• Varying amounts of vegetation were observed on the floor and embankments of the
GC-1, GC-2 and GC-3 sedimentation ponds and associated drainages. Denser
vegetation was noted in the drainage between GC-2 and GC-3 sedimentation ponds.
Vegetation does not appear to restrict the flow of water in the system.
o No maintenance or repair is required.

Gemini Mine Waste Pile:
• A second sinkhole was observed on the east side of the head frame at the top of the
waste pile. Upon inspection, it appeared that the sinkhole developed when the
surrounding soils collapsed into the concrete shaft. The sinkhole resulted in damage to
the geotextile liner and armor rock around the head frame.
o It was determined the AMRP could repair the sinkhole as part of the 2025
seasonal reclamation work
• Vegetation was reported on the northeast side at the top of the mine waste pile.
• Tire tracks were noted in the untreated base course rock cap but no evidence of trespass
was observed. Tire tracks likely result from the property owner’s vehicles.
• There were several recreational vehicles parked in a grass opening in the armor rock on
the east side of the waste pile.
o DERR will review property ownership records and determine ownership of the
grassy area.
• During previous inspections, the locks to the gates were noted as having been changed,
preventing access by the DERR. The new property owner provided the city of Eureka
with new locks to the gates, and the gates were noted as locked and secure.
6

Knightsville Canyon (KC) KC-1 and KC-2 Sedimentation Ponds:
• Vegetation, including small shrubs and trees, was observed on the embankments and
the floor of the sedimentation ponds and within the drainage channel that connects the
KC-1 and KC-2 sedimentation ponds.
o DERR should monitor vegetation and evaluate options for future removal.
• No erosion noted within the armor rock slopes sedimentation ponds.
• Wooden debris had clogged the drain pipe at the north end of the KC-2 pond.
o DERR was able to remove the wooden debris to a location outside the
sedimentation pond. No maintenance or repair is required, but vegetation should
be monitored for future removal.

Knightsville Road:
• Exposed geotextile liner was observed along the west shoulder of the road.
• Washed out untreated base course rock was observed at the outfall (west) side of the
upper culvert. The lower culvert was noted as clear. Juab County highlighted concerns
that the untreated base course along the west shoulder was clogging the downstream
culverts and exposing the geotextile liner.
o While Juab County is responsible for maintaining the road, the DERR will
explore options to replace the untreated base course along the shoulder with armor
rock.
• Several cuts in the wire fencing and bent posts were observed on the west side of the
road approximately halfway between the May Day Access Road and the Chief Mine #2
Access Road.
o DERR will repair the fence in the future, but it does not impact the protectiveness
of the remedy.

Knightsville Road Storm Drain and Culvert:
• This storm drain conveys runoff from the KC-2 sedimentation pond to the Upper
Eureka Gulch. The manholes were covered by dense vegetation in the field or by gravel
from the roadway. DERR could not locate the five manholes during the inspection.
• Minor vegetation was noted at the culvert outfall on the north side of Highway 6 but
did not restrict flow. No damage to the culvert grate was noted.
o The DERR should make an additional site visit to locate the manholes prior to the
2025 annual site inspection. No maintenance or repair is required.

Lower Godiva Mine Waste Pile:
• Minor vegetation was observed in the armor rock cap. Overall, the armored rock cap is
in good condition and protective of the remedy.
• Minor damage to the wire fencing was observed near the access gate.
• Minor amounts of general trash and debris were observed inside the fencing along
Knightsville Road indicating some trespass has occurred to the waste pile.
o No maintenance or repair is required.

7

Upper Godiva Mine Waste Pile:
• Some sparse vegetation and weeds were observed on the slopes of the waste pile.
• Tire tracks from ATV or other vehicles were observed on the top of the cap, but no
damage resulting from the vehicle traffic was observed.
• The chain-link fencing at the northwest side of the Godiva Ore Bin was damaged and
detached from the fencepost, but does not affect the remedy.
o The DERR will make repairs to the fencing around the Ore Bin.

May Day Access Road:
• The gate at the entrance to the May Day Access Road was noted as missing and likely
has been for some time. The missing gate at the entrance to the access road has likely
resulted in increased trespass. However, the evidence does not indicate that the trespass
activity has damaged the cap or affected the protectiveness of remedy
• Minor damage to the fencing on the north side of the access road was observed.
o DERR should evaluate alternatives to make repairs to the fencing.

May Day Waste Pile:
• The waste pile showed no signs of erosion of the cap.
• Minor amounts of vegetation and weeds were observed on the slopes of the waste pile.
o No maintenance or repair is required.

McChrystal Drainage Channel:
• Rock walls and slopes inside the drainage channel appeared to be in good condition and
no erosion was noted.
• Vegetation was observed on the slopes and bottoms of the drainage channel but did not
appear to restrict flows. Denser vegetation was observed at the culvert outfall on the
north side of Dublin Street.
o DERR will review options to remove the vegetation at the culvert outfall.

Open Cell Access Road:
• The access road was repaired in 2023 by the contractor working on the natural gas line
project.
• Minor vegetation was observed in the drainage channels and culverts on each side of
the road. Minor erosion rills were observed at the top of the access road.
• The gate entrances from Highway 6 and at Snowflake Mine were locked and secured.
The gate below Eagle Blue Bell had a damaged lower hinge and a missing lock.
o DERR will repair the hinge and replace the missing lock at the Eagle Blue Bell
gate.
Open Cell:
• The DERR noted that approximately 20 soil piles were staged on the north side of the
Open Cell. Construction debris, including pieces of concrete and steel posts, was found
in the soil piles. Eureka City indicated that the soils were staged to limit truck activity
in the Open Cell while the decontamination pad was non-operational.
8

o DERR will work with the city of Eureka to ensure that the soil piles are free of
construction debris and will also review the responsibilities for ensuring that
proper grading and compaction occurs following placement of the soils in the
Open Cell.
• The drain pipe located on the west end of the repository is in good condition and
elevated to a standard height as required by the Operation & Maintenance Manual.
• The vegetative cover and interior slopes of the Open Cell are in good condition with
only minor erosion.
• The gate at the top of the entrance to Open Cell remains damaged.
o DERR will work with the city of Eureka to repair the gate.

Snowflake Mine Waste Pile and Access Road:
• The armor rock slopes of Snowflake Mine are in good condition with minor vegetation
observed.
• The access road was in good condition with minor vegetation observed. No erosion was
noted in the armor rock or along the access road.
• The fencing and gates around the mine shaft at the top of the mine waste pile appeared
in good condition from available viewpoints. However, the top of the mine waste pile
was not fully accessible.
o No repairs or maintenance are required.

Lower Eureka Gulch:
• The sections of the Lower Eureka Gulch located by the city office building and City
Yard had significant vegetation and visible debris within the drainage. Several small
trees remained on the bottom of the channel. There are numerous small shrubs growing
on the sides and bottom of the lower channel.
• The culvert itself was free of obstructions.
• The flow of the channel is not limited at this time, and the overall remedy remains
intact.
• The city of Eureka is responsible for maintaining the entire Eureka Gulch. It does not
appear that treatment of the lower gulch has occurred in the past year.
o DERR will work with the city of Eureka to clear vegetation from the gulch.

Upper Eureka Gulch:
• Inspection of the Upper Eureka Gulch found small to medium-sized trees growing
inside the channel. Dense vegetation, including sagebrush, tumble weeds, grasses, and
some shrubs, covered the floor of the gulch.
• The culvert at the east end of the gulch was clear of obstructions, but encroaching
vegetation was noted in the area.
• The individual property owners are responsible for maintaining the entire Upper
Eureka Gulch. It does not appear that treatment of the upper gulch has occurred in the
past year.
o DERR will work with the city of Eureka and property owners to clear vegetation
from the Upper Eureka Gulch.

98 For each questions that were answered “yes”, provide amplifying remarks, note the location and
reference the question number:
1, 3, 4, 5, 6, 14) A sinkhole was observed to the north of the access road between the Bullion Beck
Mill site and the Gemini Mine site. The sinkhole measured 20 feet in diameter and 20 feet in depth.
The sinkhole collapsed the geotextile and armor cover cap.
2, 16, 63, 70) Minor amounts of vegetation were observed in the armor rock slopes, in the untreated
base course at the top of the Gemini Mine Waste Pile, along the Gemini and
Bullion Beck access roads, and in the Last Change drainage. Vegetation was slightly more
dense at the northeast corner at the top of Gemini Mine Waste Pile and the entrance to the
Bullion Beck Mill access road.
14)A small grassy area resulting in an interruption in the armor rock was observed along the north
east slope of the Gemini Mine Waste Pile. The area appeared to be used by residents for storage of
recreational vehicles. The ownership of the area is unknown and it is not clear if the grassy area is
part of the cap remedy.
15, 17, 18, 19, 20, 24) A second sinkhole was observed around the Gemini Mine shaft. Soils
surrounding the mine shaft appeared to be sluffing into the mine shaft though openings and voids
in the concrete. The sinkhole had collapsed the geotextile liner and armor rock cap aounr the
mine shaft.
22)Vehicle tracks were observed on the top of the Gemini MIne Waste Pile. It was unclear during
the inspection if the tracks were the result of activities by the property owner or trespass.
INSPECTION FORM FOR GEMINI MINE WASTE PILE
Page 6 of 6
99 For each of the items discussed above, indicate whether maintenance and repairs are required and
provide specific recommendations for maintenance or repairs:
1, 3, 4, 5, 6, 14) The DERR discussed the sinkholes and potential alternatives for repairs with Steve
Fluke (Utah Division of Oil, Gas and Mining - Abandoned Mine Reclamation Program - AMRP).
The AMRP will place the Gemini Mine/Bullion Beck sinkhole in it's work log for the 2025 work season.
2, 16. 63, 70) Vegetation was generally noted as minor and did not affect the protectiveness of the
remedy. Recommend continued monitoring of the vegetation through the annual inspection process
primarily noting increases in the northeast section at the top of Gemini Mine.
15, 17, 18, 19, 20, 24) See previous comment regarding discussions with AMRP regarding repair of
the sinkholes.
14) Recommend reviewing site documents to determine ownership and environmental covenants
in the area of the grassy patch. Determine cap boundaries and determine if there is a rationale for
the interruption in the armor rock.
22) It was noted as unclear if the vehicle tracks were the result of activities by the property owner
or from trespass. The gates to the access roads were locked and in good condition. The vehicle
tracks did not affect the protectiveness of the remedy. No maintenance or repairs are required.
Recommend continued monitoring through the annual inspection process for further evidence of
trespass.

2, 13, 22) Minor amounts of vegetation was observed in the exterior armor rock slopes, around the
Perimeter Road and at the top of the Open Cell berms, and within the interior slopes of the
Open Cell.
46, 53, 63, 71) Minor amounts of vegetation was observed in the drainage channel and around the
culverts OC-1, OC-2, and OC-2.
23) Small erosion rills were observed in the interior vegetative slopes of the Open Cell.
29, 32, 33) The gate to the Open Cell was damaged and non-functional. One of the gates had been
removed from the hinges and placed to the side. The lock and chains had also been removed from
the gate.
82, 83) During repairs to the decontamination pad, a rusted coupling in the drain line was discovered
to be the source of leaking and bowing causing drainage issues from the decontamination pad.
28, 76) There were 20 soils piles located on the northwest side of the Open Cell. The soil piles
contained varying amounts of construction and other debris. Soil piles had not been graded and
compacted into the floor of the Open Cell to facilitate drainage.

23) Erosion rills were noted a small in size and did not expose the geotextile liner appear to impact
the protectiveness of the remedy. Recommend continued monitoring through the annual inspection
process.
28, 76) DERR should review responsibilities for maintaining the Open Cell and ensuring that proper
grading and compaction occurs following placement of the soils. The city of Eureka is responsible for
activities related to disposal at the Open Cell but has stated that grading and compaction of the soils
at the end of the construction season is the responsbility of the DERR. DERR will also review with
the city of Eureka to ensure that only soils are to be disposed of within the Open Cell and that
construction debris must be separated out prior to transport and disposal.
29, 32, 33) The damage to the entrance gate does not impact the protectiveness of the remedy.
However, the DERR will discuss with the city of Eureka that the gate still needs to be repaired to
prevent unwanted trespass.

APPENDIX C
O&M Maintenance and Repair Work Assignment #13

2024 O&M Maintenance and Repair Work – Work Assignment #13
The Level of Effort contractor, AECOM, and their subcontractor, 5seventeen Company,
conducted the O&M repair work under the Work Assignment #13 during the week of October
14th. The O&M repair work included the following items:
1) Repair of the drain line from the decontamination pad at the Open Cell Repository. The
work assignment initially called for the replacement of the fire hydrant at the Open Cell
Repository. However, the city was unable to turn off the municipal water to the hydrant
without disrupting service to the community. Further inspection found that the hydrant was
able to supply water to the decontamination pad. However, a rusted coupling in the drain
line just south of the access road was determined to be a source of drainage issues for the
decontamination pad. Repairs were made to the drain line, and the city was provided with
the new backflow preventer and fire hose to install at the Open Cell hydrant.
2) Repair of three erosion rills along the May Day Access Road along the north shoulder to the
Upper Godiva Mine Waste Pile.
3) Repairs to the erosion rill/washout of the untreated base course on the northeast corner of the
Upper Godiva Mine Waste Pile. Untreated base course was reinforced with armor rock to
prevent future washout events.
4) Removal of wooden floorboards and repair of the geotextile and untreated base course cap at
the burned storage shed/electrical shop building atop Chief Mine No.1;
5) Repair of the stock fence and gate on the east side of the Chief Mine No. 1; and,
6) Repair of the chain-link fence and east gate at Eagle Blue Bell head frame.
