SITE DESCRIPTION

The Elizabeth Mine is an abandoned copper mine located on Mine Road in the Village of South Stratford within the Town of Stratford Orange County Vermont [3 17 p 35] Geographic coordinates of the property as measured from the center of Tailings Pile No 1 are approximately 43deg4926 north latitude and 72deg1944 west longitude (Figure 1) [59] There are no tax assessors maps for the property [5]

The Elizabeth Mine site is situated in a rural setting on the east side of Copperas Hill Topography of the area consists of north-south trending hills and valleys [3] Woodlands surround the mine property [3 17 p 35] Undeveloped and residential properties border the sites western margin [3 6 p 39] Site elevations range from approximately 1000 feet to 1300 feet above mean sea level [3] The property consists of three mine tailings piles two open-cut mines several adits (horizontal mine entrances) underground shafts and tunnels ventilation shafts and several former ore processing buildings Other on-site structures include those previously used for office space a shop a solventoil storage shed an air compressor building and a garage The majority of the buildings are in a dilapidated condition [6 p 40] However one of the buildings and a trailer on the property are rented for residential purposes and the garage is used to store equipment (Figure 1) [6 p 3951 p 2]

Deposits at the Elizabeth Mine were discovered in 1793 [20 p 8 26 p 76] The mine operated from the early 1800s until its closure in 1958 [30 p 2] The ore was initially valued for its iron content and then its pyrrhotite content from which copperas (iron sulfate) was produced [20 pp 8 67] Circa 1830 the deposit was primarily exploited for its copper content based upon the recognition that a significant amount of chalcopynte (copper iron sulfide) was disseminated in the pyrrhotite [20 pp 8 67] For nearly a century intermittent production came from the open-cut mine as underground work did not begin until 1886 [20 p 67] During the early mining operations several copper smelters were built on the property [20 p 67] Between 1830 and 1930 approximately 250000 tons of ore were mined from which approximately 10500000 pounds of copper were produced [20 p 8] From 1943 to 19582967000 tons of ore were mined producing more than 90000000 pounds of copper [20 p 10 26 p 84] All mining operations ceased in February 1958 [20 p 10] At the close of the mining operation the mine property encompassed approximately 1400 acres [27 p 2]

Past operations at the property consisted of mining copper smelting and ore processing As a result three mine tailings piles and two open-cut mines were generated onsite Previous studies refer to the tailings as piles 1 2 and 3 and this same nomenclature is used in this HRS package (Fig 2) The processed tailings in Pile No 1 were generated between 1943 and 1958 during the latter period of the mining operation Ore was ground for flotation through an onsite mill [48 p 7] As copper and pyrrhotite were chemically separated from the ore tailings sank to the bottom of a flotation separator and were removed [26 p 82] Tailings were dammed to form an impoundment and then were carried via open troughs to a tailings pond for sedimentation [48 p 6 27 p 2] As the valley filled with tailings the piles north face rose approximately 100 feet above the natural streambed of Copperas Brook [3 6 p 30] Tailings Pile No 1 is a flat-topped pile (plateau-like feature) on the lower portion of the property and covers approximately 30 acres [48 p 15 6 p 30] This pile is comprised of a fine-grained material uniformly reddish-brown in color at the surface and is the largest accumulation of tailings onsite [27 p 6 31 p 17 6 p 30]

Tailings Pile No 2 overlies Tailings Pile No 1 at the southwest end of the massive pile [3 6 p 34 27] (Figure 3) Like Tailings Pile No 1 Tailings Pile No 2 forms a raised plateau and covers approximately 5 acres [48 p 15] This pile rises approximately 30 feet above the surface of Tailings Pile No 1 [3 6 p 34] The north slope is bare and eroded [6 p 34] An erosion gully is present on the east side of Tailings Pile No 2 where a once buried conduit system has been undermined exposed and destroyed [27 pp 8 A-5 A-7] Tailings in Pile No 2 were also generated during the 1900s and deposited similarly to those in Pile No 1 [48 p 7]

Tailings Pile No 3 is located further southwest and upslope of Tailings Pile No 2 This pile is immediately east of one of the two open-cut mines and covers approximately 6 acres (Figure 2) [48 p 12] Tailings Pile No 3 is comprised of multiple piles of red and yellow-colored coarse-textured material and slag [27 p 6 30 p 5 31 p 23 6 p 36] Waste in these piles was generated from mining and copper smelting operations during the 1800s and early 1900s [27 pp 12 6] Six copper smelters were built on the property between 1830 and 1916 [20 p 67] Slag was observed in Tailings Pile No 3 some pieces exhibited an iridescent surface [6 p 36]

When mining operations were abandoned many of the underground areas flooded with groundwater An air shaft depicted on Figures 1 and 2 once tunneled to provide ventilation for the underground work areas currently discharges acid mine drainage to the ground surface Drainage from this shaft flows overland and empties into an unnamed brook which discharges to the West Branch Ompompanoosuc River [27 p 2 31 p 25]

RI00461F October 2000

The tailings on the property are rich in metals and sulfides As water passes over and through the tailings sulfunc acid is produced and the metals within the tailings are dissolved and mobilized This results in acid mine drainage [30 p 8] Acid mine drainage contributes an elevated load of metals to Copperas Brook and the West Branch Ompompanoosuc River [30 p 8 31 pp 11 16]

The Elizabeth Mine has been previously investigated by State and Federal agencies and private companies As part of the various studies one or more samples of mine tailings surface water sediment fish tissues ground water and drinking water have been collected and analyzed for metals The results indicated the presence of metals that exceeded background levels [27 pp 9 11 30 pp 56 31 pp 25614-16 32 33 pp i 1 4-11]

Pathways Components or Threats Not Scored

The MRS site score forthe Elizabeth Mine site is based on threats posed by the site to the surface water migration pathway After a review of the four pathways it was determined that the groundwater and air migration pathways as well as the soil exposure pathway would not contribute significantly to the overall site score Therefore these pathways have not been included in this MRS package

According to previous investigations VOCs (acetone and an unidentified aliphatic ester) and PCBs were detected in various media at the site however results were not used for scoring purposes in this MRS package These substances were detected in sources that were neither well defined nor considered significant to the primary sources onsite

NOTES TO THE READER

Laboratory Analysis - The surface water samples were analyzed for Target Analyte List (TAL) metals through the EPA Contract Laboratory Program (CLP) according to CLP Statement of Work (SOW) ILMO 4 0 The sediment samples were analyzed for TAL metals by a procured laboratory under a Delivery of Analytical Service (DAS) Work assignment in accordance with the CLP ILMO 4 OSOW as modified by technical specification S99shyRAC1-108 The CLP Method ILMO 4 0 was modified to compensate for the low percentage of solids (high percentage of moisture) in the sediment samples Additionally the method had a provision for low sample pH and a high concentration of metals

Contract Required Detection Limit (CRDL)

Water Samples - The Contract Required Detection Limit was used as the minimal sample reporting limit for each metal analyzed [56]

Sample Quantitation Limit (SQL) - SQLs presented in this MRS package were determined accordingly

SoilSediment Samples - The Instrument Detection Limit (converted from micrograms per liter OugL) to milligrams per kilogram (mgkg)) corrected by the percent solids and the amount of sample analyzed was used as the minimal sample reporting limit or SQL for each metal analyzed [67 pp 1-4]

OTHER POSSIBLE SOURCES

The following sources were identified during previous investigations however sufficient documentation for scoring these sources was not identified Therefore they were not used in this MRS package for purposes of scoring

In 1989 the State of Vermont determined portions of the Elizabeth Mine site were used as an illegal dump site for out-of-state refuse construction debris and possibly domestic sewage sludge [49 52 p 4 16 p 1] The dump site was located in the west-central portion of the tailings in Pile No 1 [16 p 1 51 p 2] Vermont ANRDEC personnel collected a sludge sample from an excavated pit m the source area The sample was analyzed for TCLP metals and VOCs [16 p 1] The Vermont DEC determined the sludge material was nonshyhazardous [16 p 1] The materials were left in place and the pit was backfilled [16 p 1] Additional file information regarding this source was not found

Transformers

In 1988 personnel from the Army Corps of Engineers (ACOE) were onsite and observed transformers in the vicinity of Tailings Pile No 2 The ACOE reported this discovery to the Vermont DEC and informed them that the transformers appeared to be leaking [16 p 2] A follow-up inquiry by the Vermont DEC revealed that the transformers were owned by the former mining company and had been on site at least 30 years [51 p 3 55]

In August 1990 the DEC conducted soil sampling activities at the Elizabeth Mine for the Screening Site Inspection Soil samples SB-3 and SB-4 were collected from transformer storage areas and analyzed for PCBs [24 Fig 1 App B p 20 Tab 6] PCBs were detected in soil sample SB-3 at a concentration of 221 89 micrograms per kilogram [24 App B p 21 Tab 7]

In November 1991 a total of 20 transformers were inspected by the DEC [57 pp 145] Sixteen transformers were stored in a compressor building and four were stored outside near Tailings Pile No 2 [57 p 1] Oil-stained soil was observed around one of the transformers near Tailings Pile No 2 [57 p 1] As a result of the inspection the DEC confirmed that one of the transformers stored outside was leaking Oil in a majority of the transformers was sampled [57 p 1]

Analytical data indicates that one transformer stored on site contained oil with a PCB concentration of 300 micrograms per gram [57 pp 19] By order of the State the property owner was required to remove two of the transformers and excavate contaminated soil around the leaking transformer for proper disposal [57 p 2] The property owner responded with proposed plans for the removal [54 pp 12] No follow-up inspections or post-removal soil sampling activities were performed by the State [16 p 2] Removal activities were proposed after the Screening Site Inspection was initiated Additional file information regarding this source was not found

Underground mine workings at the Elizabeth Mine extend to the West Branch Ompompanoosuc River [48 p 7] These areas were accessed from the open-cuts adits in the walls of the open-cuts and vertical shafts [48 p 3] Portions of the underground workings flooded after the mining operation was abandoned [27 p 2] None of the subsurface (tunnels shafts etc ) workings of the mine were investigated or scored in this MRS package

Other Mine Waste

There are two open-cut mines in the southwest portion of the site that represent some of the oldest workings at the Elizabeth Mine (Figure 1) File information indicates that there are several small piles of mine waste down slope of these open-cuts [48 pp 10 12 30 pp 521] These piles were not investigated and were not scored in this MRS package

SOURCE DESCRIPTIONS

22 Source Characterization

Number of the source 1

Name and description of the source Tailings Pile No 1 and Tailings Pile No 2 (Piles)

Source 1 represents two piles of tailings that were generated by mining milling and ore processes on the property Tailings Pile No 1 and Tailings Pile No 2 are considered one source because they consist of fine-grained material generated from a flotation mill that was used during the latter part of the mining operation (1943shy1958) [48 p 7] The total production from 1943 to 1958 was 2967000 tons of ore containing more than 90000000 pounds of copper [20 p 10 26 p 84] Geochemical data for composite surface soil tailings shows chemical differences between the younger tailings in Pile Nos 1 and 2 and the older tailings in Pile No 3 [48 P 28]

The two piles cover approximately 35 acres [48 p 15] Tailings Pile No 1 forms a plateau-like feature (i e pile) on the lower portion of the property and occupies approximately 30 acres Tailings Pile No 2 overlies Tailings Pile No 1 at the southwest end of Tailings Pile No 1 Like Tailings Pile No 1 tailings in Pile No 2formaraised plateau and cover approximately 5 acres [48 p 15] The fine-grained tailings are comprised of silt and sand sized particles uniformly reddish-brown in color [6 pp 30 34 3 27 p 6 31 p 17] Various amounts of pyrrhotite jarosite goethite gypsum mica feldspar and quartz are some of the minerals that make up the fme-gramed tailings [48 p 15]

Ore was crushed into a powder and ground for flotation through an onsite mill [26 p 82 48 p 7] Copper and pyrrhotite were extracted using copper sulfate sulfunc acid cyanide pentasol amyl xanthate pine oil and pentasol 124 alcohol in the flotation circuit [26 p 82 48 pp 5-6] Tailings sank to the bottom of the flotation separator and were decanted via open troughs to a tailings pond for sedimentation [26 p 82 48 p 6 27 p 2] Decant towers were built into the piles to dewaterthe tailings [48 p 7] The decanted water flows through a buried conduit to the base of the pile at the northeast corner of Tailings Pile No 1 and discharges from a culvert into the natural streambed of Copperas Brook [27 p 8 48 p 7 6 p 41]

In October 1999 an EPA contractor collected source samples from Tailings Pile No 1 (Figure 2) The samples were analyzed for Target Analyte List (TAL) metals according to the CLP ILMO 4 0 Statement of Work as modified by technical specification S99-RACI-108 [14 pp 1-15]

Location of the source with reference to a map of the site

Tailings Pile No 1 is located in a valley east of Mine Road situated between Copperas Hill to the west and Gove Hill to the east (Figure 2) [3 6 p 33] Tailings Pile No 2 overlies the southwest portion of Tailings Pile No 1 (Figure 2) [3 6 p 34 27 Fig 3 38]

Containment

Release via overland migration andor flood

The slopes of Tailings Pile Nos 1 and 2 are unvegetated and deeply eroded While some erosion control measures have been taken to reduce the migration of tailings into the environment (i e partial soil cover on top of Tailings Pile No 1 and vegetation on top of Tailings Pile No 2) both piles are still subject to significant weathering and erosion processes [6 pp 30 32-35]

There is no engineered cover liner or functioning and maintained run-on control system and run-off management system to prevent migration of hazardous substances from the tailings piles into Copperas Brook and the West Branch Ompompanoosuc River [6 pp 30-35]

A containment factor of 10 has been assigned to Source 1 [1 p 51609 Tab 4-2]

The Hazardous Waste Quantity for Source 1 was calculated based on the Area Assigned Value The Hazardous Constituent Quantity Hazardous Wastestream Quantity and Volume Assigned Values were not scored (NS) for Source 1 because sufficient documentation for scoring purposes was not identified [1 p 51591]

2 4 2 1 4 Area

Multiple different average values for Source 1 (Tailings Pile Nos 1 and 2) are reported in file information In a 1989 study the Army Corps of Engineers reported that the tailings in Pile Nos 1 and 2 covered approximately 32 acres and 5 acres respectively [27 p 6] In a 1999 report the US Geological Survey states that Tailings Pile No 1 represents a 30-acre accumulation of fine-grained tailings and Tailings Pile No 2 covers 5 acres [48 p 15] In April 1999 a member of the Elizabeth Mine Study Group indicated that Tailings Piles Nos 1 and 2 covered approximately 38 acres [6 p 39]

EPA contractor personnel estimated the surface area of Source 1 (Tailings Pile Nos 1 and 2) at 40 acres by using a topographic map and a grid system overlay This area represents a two-dimensional surface area encompassed by the pile and therefore does not account for the surface area represented in the third dimension (contour lines) of the topographic map [38 1 p 51591 Tab 2-5]

For the purposes of this HRS package the acreage reported by the USGS (35 acres) will be used as the area of the source

SD-Characterization and Containment Source No 2



Name and description of the source Tailings Pile No 3 (Pile)

Unlike the processed fine-grained material in Pile Nos 1 and 2 (Source 1) Pile No 3 (Source 2) is comprised of a coarse-textured material from early mining operations (19th century) when ore recovery was not as refined [30 p 5 27 p 6 48 p 12 6 p 36] Geochemical data for composite surface soil tailings shows chemical differences between the older tailings in Pile No 3 and the younger tailings in Pile Nos 1 and 2 [48 p 28] Therefore Tailings Pile No 3 (Source 2) is being evaluated and scored separately from Tailings Pile Nos 1 and No 2

Tailings Pile No 3 covers approximately 6 acres and consists of several mounds of mine wastespoils USGS reports that the description mine spoil is more befitting than tailings because there is a degree of uncertainty to which metals were extracted from the waste products during processing More metals may be present in Tailings Pile No 3 versus Tailings Pile Nos 1 and 2 [48 p 12] Less efficient metal extraction techniques were used prior to the development of the modern flotation separator used for reprocessing the preexisting mine spoils [48 pp 5 12 27 p 6 26 p 82] Tailings Pile No 3 is heterogeneous in color varying from red to yellow-colored mounds [6 p 36] The varying colors reflect the dominant soil minerals [48 p 12] Reddish-colored mounds are hematite-rich (iron oxide mineral) and yellowish-colored piles are jarosite-nch (iron hydroxy sulfate mineral) [48 P 12]

The Elizabeth Mine was worked intermittently over a period of more than 100 years [27 pp 12] Ore was processed by a variety of techniques Six copper smelters were built and operated at the mine in the 19m century [20 p 67] Slag (product of onsite smelting) is present in Tailings Pile No 3 [6 p 36 31 p 23] Someoftheslag surfaces were iridescent [6 p 36] Between 1830 and 1930 approximately 250000 tons of ore were mined from which 10500000 pounds of copper were produced [20 p 8]

In August 1990 the Vermont DEC conducted sampling activities at the Elizabeth Mine for the Screening Site Inspection Soil sediment surface water groundwater and drinking water samples were collected [24 App B p 20 Tab 6] Samples were submitted to the Vermont DEC laboratory for one or more of the following analyses metals semivolatile organic compounds (SVOC) volatile organic compounds (VOC) and PCBs [24 App B p 20 Tab 6] A source sample SB-1 was collected from Tailings Pile No 3 Analytical results indicate concentrations of arsenic chromium copper lead mercury selenium and zinc [24 App B p 20 Tab 6 p 21 Tab 7 App C p 29]


Tailings Pile No 3 is located west of Mine Road and east of the northernmost open-cut mine This pile extends from the open-cut across the unimproved access road and is approximately 1500 feet southwest (upslope) of Tailings Pile No 2 (Figures 1 and 2) [3 27 p 7] Copperas Brook originates from this tailings pile and flows east northeast toward Tailings Pile No 1 and Tailings Pile No 2

Containment


Tailings Pile No 3 consists of mine waste associated with earlier periods of the mines history that was dumped in piles [27 p 4] Copperas Brook flows from Tailings Pile No 3 through an erosion gully in Tailings Pile No 2 and onto the surface of Tailings Pile No 1 [27 pp A-5toA-7 30 p 216 p 3148 p 7 12] Copperas Brook flows along the surface and eroded channels of the tailings piles as well as through the existing concrete conduit that has been largely undermined and destroyed [27 pp A-5 to A-7 6 p 31]



Tailings Pile No 3 is almost devoid of vegetation North-facing slopes of the waste piles have deep erosion channels [6 pp 3637] Wood planks and bricks possibly remnants of smelters or processing buildings were observed in some of the piles [6 p 37]

The slope of Tailings Pile No 3 is unvegetated and deeply eroded [6 pp 3637] No erosion control measures have been taken to prevent the migration of tailings into the environment There is no engineered cover liner or functioning and maintained run-on control system and run-off management system to prevent migration of hazardous substances from the tailings in Pile No 3 into the environment [6 p 37]





In August 1990 the Vermont DEC conducted sampling activities at the Elizabeth Mine for the Screening Site Inspection A source sample (SB-1) was collected from Tailings Pile No 3 [24 Figs land 2 p 7] The sample was submitted to the Vermont DEC laboratory for metals and semtvolatile organic compound analyses [24 App B p 20 Tab 6]

Tailings Pile No 3 does not appear on the USGS topographic map for the South Strafford Quadrangle Vermont An EPA contractor could not estimate the size of the pile using the grid overlay as was done in the evaluation of Source 1 File information indicates Tailings Pile No 3 covers approximately 6 acres [48 p 12] Therefore 6 acres was used as the area of Tailings Pile No 3 for this HRS package

1 acre = 43560 ft2

6 acres = 261360 ft2

SD-Charactenzation and Containment Source No 3



Name and description of the source Air Shaft Discharge (acid mine drainage)

Source No 3 represents acid mine drainage discharging from an air shaft that once provided ventilation to underground work areas [27 p 2] After the Elizabeth Mine was abandoned lower portions of the mine (including the air shaft) flooded [27 p 2] As water comes into contact with the ore and the host rock in the underground workings metals are leached and acid mine drainage is produced [30 p 24] This drainage flows upgradient through the air shaft and discharges onto the ground [31 p 1925pp 23] Onceon the ground the drainage flows overland approximately 35 feet to the west and empties into an unnamed brook The unnamed brook empties into the West Branch Ompompanoosuc River [45 pp 11-13]

A mound of materials have accumulated around the air shaft The dimensions of this mound are approximately 40 feet (L) x 20 feet (W) x 5 feet (H) [45 pp 1213] Studies indicate that the materials consist of iron salts and aluminum minerals that have precipitated out of the acid mine drainage [31 p 19 48 p 17] The precipitates are typically found in areas where acidic waters mix with near neutral waters that increase the pH values to around 5 the value at which aqueous aluminum hydrolyzes to form AI(OH)2+[48 pp 17 19] The pH of the acid mine drainage was approximately 5 based on water quality measurements collected by an EPA Contractor [45 P 11]

A drainage pipe positioned at the air shaft directs the flow of the discharge The acid mine drainage flows through the pipe and empties onto the ground at the base of the mound The area through which the discharge flows consists of shallow ponded water muck-like organic-rich soil decayed leaves and dead trees [45 pp 12 13]

Previous studies indicate that the acid mine drainage discharging from the air shaft contributes less than 3 percent of the total metal load reaching the West Branch Ompompanoosuc River [31 p 2] The organic material in the muck-like area through which the drainage flows acts as a filter and absorbs metals [31 p 26]


The air shaft is located approximately 0 6 of a mile upstream of the confluence between Copperas Brook and the West Branch Ompompanoosuc River It is at least 50 feet above the south bank of the West Branch Ompompanoosuc River The air shaft is approximately 0 7 of a mile east of the intersection between Tyson Road and Route 132 and is visible from the road [45 pp 12 29]

Containment


In OctoberNovember 1999 an EPA Contractor collected a sample of the acid mine drainage (SW-10) discharging from the pipe a sediment sample (SD-13) from the unnamed brook at PPE No 2 and a surface water sample (SW-08) at the confluence of the unnamed brook and the West Branch Ompompanoosuc River Based on analytical data there is evidence of hazardous substance migration from the air shaft discharge to the unnamed brook and West Branch Ompompanoosuc [13 p 7 15 p 10 50 p 22 ]

There is no engineered cover liner or functioning and maintained run-on control system and run-off management system to prevent migration of hazardous substances from the air shaft discharge into the environment [45 pp 11-13]





In November 1999 an EPA Contractor collected a sample of the acid mine drainage MAMBOO (SW-10) from the drainage pipe (Figure 2) [45 pp 11-13] The sample was analyzed for TAL metals according to the CLP ILMO 4 0 Statement of Work A Tier III data validation was performed by the EPA Contractor The data were validated according to the Region I EPA-NE Laboratory Data Validation Functional Guidelines for Evaluating Inorganic Analyses modified February 1989 [15 pp 1-10]

SWOF-Surface Water Overland FlowFlood Migration Pathway

4 1 OVERLANDFLOOD MIGRATION COMPONENT

4 1 1 1 DEFINITION OF HAZARDOUS SUBSTANCE MIGRATION PATH FOR OVERLANDFLOOD COMPONENT

The Elizabeth Mine is located within the Copperas Brook and Lord Brook watersheds [30 pp 19-21] A drainage divide separates the two open-cut mines [32 Fig 2 48 p 12] Drainage belowthe northern open-cut mine flows into Copperas Brook and empties into the West Branch Ompompanoosuc River [3 30 p 21] Drainage from the southern-most open-cut mine enters Lord Brook which also discharges to theWestBranch Ompompanoosuc River [3 30 pp 19 2148 p 12] For HRS purposes the Elizabeth Mine is located within a single watershed because Copperas Brook and Lord Brook flow into the West Branch Ompompanoosuc River within the 15-mile target distance limit for sources at the site [1 p 51605]

Precipitation at the Elizabeth Mine site either flows overland as surface runoff into Copperas Brook or infiltrates and leaches through the tailings or flows andor falls directly into the open cuts and adits [3 27 p 2 32 pp 45]

Drainage via Copperas Brook

The Elizabeth Mine site is drained primarily by Copperas Brook [3 27 p 8] The Copperas Brook watershed spans approximately 300 acres from the east side of Copperas Hill to the west side of Gove Hill [30 pp 19-21] Copperas Brook begins at the base of Tailings Pile No 3 (Figure 2) [30 p 21] Prior to the emplacement of Tailings Pile Nos 1 and 2 the Brook flowed through a valley and emptied into the West Branch Ompompanoosuc River [27 p 8 68] During the latter period of mining (1943-1958) Copperas Brook was rerouted through a concrete pipe buried beneath Tailings Pile Nos 1 and 2 [27 p 8 31 p 17] Decant towers were constructed to dewater the tailing slurry deposited in the valley The slurry supernatant was routed through the concrete conduit (rerouting Copperas Brook) to the base of Tailings Pile No 1 [27 p 8 31 p 17]

Since mining operations were abandoned erosion has exposed undermined and destroyed the drainage conduit system on the east side of Tailings Pile No 2 [27 pp 8 A-5 31 p 17]

Currently Copperas Brook flows overland from the base of Tailings Pile No 3 through an eroded gully along Tailings Pile No 2 and onto the surface of Tailings Pile No 1 where it enters ponded water [6 p 31 48 p 7] The decant tower on the north-northeast side of the ponded water reroutes the surface water underneath Tailings Pile No 1 via a deteriorated system of concrete pipes to the base of the pile [27 p 8] Copperas Brook discharges via a culvert at the northeast corner of the tailings pile [6 pp 3031] In addition to flowing through the decant tower water and acid mine drainage also flows through an eroded gap between the tailings and the outside of the tower [6 p 31]

Drainage via Intermittent Flow

During precipitation events surface runoff from the Elizabeth Mine site also flows west across Tailings Pile No 1 and empties into a drainage ditch and erosion channels (Figure 2) [6 p 43 30 p 21] Precipitation that infiltrates the tailings emerges as seeps along the base of Tailings Pile No 1 [6 pp 3343] These seeps and intermittent streams of acid mine drainage eventually discharge into and follow the natural streambed of Copperas Brook [68 6 p 33]

R100461F October 2000 30

Drainage via Open-cuts and Adits

The open-cuts and adits are connected by underground shafts [32 pp 45 20 Plate 4 App I p 67] Underground workings extend to the West Branch Ompompanoosuc River [48 p 7] Precipitation that falls into the open-cuts and adits likely moves through the underground workings via tunnels [32 pp 45 20 Fig 13 p 28] An air shaft once built to provide ventilation to underground workings flooded after mining operations were abandoned [27 p 2] This air shaft discharges acid mine drainage to the ground surface [6 p 44 27 p 231 p 19 45 pp 11-13]

Two probable points of entry (PPEs) have been identified where hazardous substances enter the surface water pathway at the site (Figure 2) [10]

PPE1 - Source Nos 1 and 2

PPE1 is at a culvert located at the base of Tailings Pile No 1 where Copperas Brook exits a buried conduit Surface runoff from Tailings Pile Nos 1 and 2 (Source 1) flows overland and intersects Copperas Brook on the east side of Tailings Pile No 2 and on the surface of Tailings Pile No 1 where it enters a small pond [3 48 p 7] Surface runoff from Tailings Pile No 3 (Source 2) flows overland and intersects Copperas Brook at the base of the pile [3 30 p 21] Streamflow in Copperas Brook is considered intermittent at elevations above PPE1 and perennial at elevations below PPE1 [4 25 pp 1-3]

From the base of Tailings Pile No 1 Copperas Brook flows north approximately 0 4 of a mile downstream and discharges into the West Branch Ompompanoosuc River At its confluence with the West Branch Ompompanoosuc River surface water flows southeast approximately 4 4 miles and merges with the Ompompanoosuc River The Ompompanoosuc River flows southeast approximately 1 3 miles to the Union Village Flood Control Dam Belowthe dam the Ompompanoosuc River flows southeast approximately 3 2 miles and empties into the Connecticut River [3 10 28 34-37] The 15-mile surface water target distance limit (TDL1) from PPE1 is approximately 5 7 miles downstream of the Ompompanoosuc RiverConnecticut River confluence (Figure 3) [10 34-37]

PPE2 - Source No 3

PPE2 is in an unnamed brook west of the air shaft (Source 3) (Figure 2) Acid mine drainage discharged from the flooded shaft flows overland approximately 35 feet and intersects the unnamed brook [45 pp 11-13] Streamflow in the unnamed brook is considered intermittent at elevations above PPE2 and perennial at elevations below PPE2 [25 pp 23]

From PPE2 the unnamed brook flows north approximately 25 feet and discharges into the West Branch Ompompanoosuc River The West Branch Ompompanoosuc River flows approximately 0 6 miles southeast and converges with drainage from PPE1 at the confluence with Copperas Brook Below this confluence the West Branch Ompompanoosuc River flows east-southeast approximately 4 3 miles and discharges into the Ompompanoosuc River The Ompompanoosuc River flows southeast approximately 1 3 miles to the Union Village Flood Control Dam Belowthe dam the Ompompanoosuc River flows southeast approximately 3 2 miles and empties into the Connecticut River The 15-mile surface water TDL (TDL2) from PPE2 is approximately 5 6 miles downstream of the Ompompanoosuc RiverConnecticut River confluence (Figure 3) [10]

The average annual flow rate of Copperas Brook is estimated at 0 32 cubic feet per second (cfs) as measured atthe mouth ofthewaterbody [25] For the purposes of the MRS scoring package Copperas Brook is considered a minimal stream (flow rate less than 10 cfs) [1 p 51613 Tab 4-13]

The average annual flow rate of the unnamed brook adjacent to the air shaft was based on the flow contributed by the air shaft The average annual flow rate of the air shaft is estimated at 0 12 cfs [25 p 2] The unnamed brook is considered a minimal stream for HRS purposes [1 p 51613 Tab 4-13]

According to the USGS the closest gauging station to the West Branch Ompompanoosuc River is in a tributary to the River in South Strafford Vermont (Gauging Station 01140800) The drainage area reported at this station was not used to estimate a flow rate of the West Branch Ompompanoosuc River because it characterizes the tributary and not the River [40]


An EPA Contractor estimated the flow rate of the West Branch Ompompanoosuc River based on the drainage area of the River and the mean annual runoff rate that was calculated for the eastern portion of Orange County Vermont According to the calculations streamflow in the West Branch Ompompanoosuc River travels at approximately 133 cfs [22 43 44 pp 12] Bodies of water with a streamflow at this rate are considered moderate to large streams (greater than 100 to 1000 cfs) [1 Tab 4-13 p 51613]

Gauging station 01141500 in the Ompompanoosuc River at Union Village Vermont is approximately 6 5 miles downstream of PPE1 [310] The flow rate at this station was determined from USGS data for the drainage area and the mean annual runoff rate for the region [39 43] Based on calculations the flow rate of the Ompompanoosuc River at gauging station 01141500 is approximately 173 cfs [8 44 pp 12] There are no gauging stations in the Connecticut River within the 15-downstream mile target distance limit for the surface water pathway Gauging station 01138500 at Wells River Vermont is the most upstream station At this location the Connecticut River flows at a rate of approximately 3516 5 cfs [9] Gauging station 01156500 at Vernon Vermont is the most downstream station in the Connecticut River Streamflow at this station is approximately 8333 8 cfs based on USGS data for the drainage area and a mean annual runoff rate for the region [9] Bodies of water with streamflow rates greater than 1000 to 10000 cfs are considered large streams to rivers [1 Tab 4-13 p 51613]

All stream flow calculations were based on average annual runoff values (inches) converted to flow per square mile (cfsmi2) For the eastern portion of Orange County Vermont a conversion factor of 1 33 cfs per mi2 was used [43 44 pp 12]

There are no known drinking water intakes along the 15-mile downstream target distance limit for the surface water pathway [19 23 28]

Approximately 1 4 miles of wetland frontage exist along the 15-mile downstream surface water pathway [34-37 61 63 69]

The State of Vermont Nongame and Natural Heritage Program database lists one state and federally endangered species and one state threatened species for the 15-mile downstream surface water pathway [12 18 46]


SWOF-Observed Release

4121 LIKELIHOOD OF RELEASE

41211 Observed Release

An observed release was established by direct observation and chemical analysis Documentation for both is discussed below

Direct Observation

Following the abandonment of the Elizabeth Mine portions of the mine flooded [27 p 2 32 p 3] Theairshaft once used for ventilation of underground workings discharges acid mine drainage (Figure 2) [27 p 2 25] The acid mine drainage discharged from the air shaft spills onto the ground Acid mine drainage that does not pond or infiltrate the ground flows overland and discharges into an unnamed brook approximately 35 feet west of the airshaft This discharge was observed by an EPA contractor on Novembers 1999 [45 pp 11-13] As part of a study discharge from the air shaft was documented to flow continuously from October 1998 to September 1999 [25 p 2] The unnamed brook is a perennial body of water between PPE2 and the West Branch Ompompanoosuc [25 pp 1-3] Analytical results for sample MAMBOO (SW-10) collected from the end of the discharge pipe at the air shaft documents the presence of hazardous substances associated with this source [15 p 10] Therefore based on sample SW-10 from Source 3 an observed release by direct observation has been documented The following hazardous substances were documented in Source 3

Chemical Analysis - Surface Water Samples

In OctoberNovember 1999 an EPA Contractor conducted sampling activities as part of this MRS effort Surface water samples were collected and analyzed for total metals through the EPA Contract Laboratory Program (CLP) according to the EPA CLP Statement of Work (SOW) ILMO 4 0 [6 p 27]

Background surface water samples were collected in an unnamed stream and from the West Branch Ompompanoosuc River [45 pp 6-710] Surface water pathway samples were collected in Copperas Brook and the West Branch Ompompanoosuc River [45 pp 1-358914] Analytical results from the pathway samples


were compared to the background surface water concentrations to determine if there was an observed release via chemical analysis

Background surface water samples were collected from the unnamed stream located east of Tailings Pile Nos 1 and2 andtheWestBranchOmpompanoosucRiver(Figure2)[6pp 46-48 45 pp 6-8] Several surface water samples were collected to establish background concentrations because of multiple probable points of entry (PPEs) and variable flow rates in m-water segments from each PPE [6 p 48] Analytical results from background samples (SW-05 SW-06 and SW-09) were compared to analytical results from surface water pathway samples to establish an Observed Release by chemical analysis Additional characteristics including sample media streamflow environmental setting and meteorological conditions under which samples were collected were considered in establishing similarity between the background and release samples

The headwaters of Copperas Brook begin in Tailings Pile No 3 therefore a background surface water sample representative of this pathway segment could not be collected [6 p 43 31 p 23] The entire brook appears to be influenced by acid mine drainage [6 p 46]

Unnamed Stream

The unnamed stream flows west-northwest and discharges into ponded water on top of Tailings Pile No 1 (Figure 2) [6 p 46] A background sample SW-09 was collected approximately 250 feet upstream of the confluence between the pond and the unnamed stream [45 p 10] The streambed at this location was not stained and appeared to be outside the area influenced by acid mine drainage and past mining operations [6 p 47]

Background sample SW-09 from the unnamed stream and release sample SW-07 from Copperas Brook both surface water samples were collected from the Copperas Brook watershed during a ram event [30 p 216 p 47] Streamflow in the unnamed stream during sampling was minimal [6 pp 4647] The unnamed stream is likely an intermittent surface water body [6 p 47]

Stream flow in Copperas Brook is intermittent above the culvert at the base of Tailings Pile No 1 [6 p 41] According to the USGS the upper portion of Copperas Brook (between Tailings Pile Nos 2 and 3) tends to go dry during summer months [4] Streamflow measurements at the mouth of Copperas Brook over a 12-month period from October 1998 to September 1999 indicate an average yet continuous flow rate of less than 1 cubic feet per second (cfs) [25 pp 1-3] This data supports the characterization that Copperas Brook is a perennial waterbody with a minimal flow rate [1 p 51613 Tab 4-13]

The unnamed stream and Copperas Brook appear to be similar bodies of water based on stream flow and environmental setting [6 p 47] Surface water samples from each were collected similarly using a direct dip procedure [45 pp 810]

West Branch Ompompanoosuc River

The West Branch Ompompanoosuc River flows east at the base of Copperas Hill and empties into the Ompompanoosuc River [3] Drainage from the Elizabeth Mine site flows into the West Branch Ompompanoosuc River via Copperas Brook or an unnamed brook adjacent to a flooded and flowing air shaft at the base of Copperas Hill [3 6 p 44 45 pp 11-13]

Background surface water samples SW-05 and SW-06 were collected in the West Branch Ompompanoosuc River (Figure 2) [45 pp 67] Sample locations were selected approximately 25 to 50 feet upstream of the confluence between the unnamed brook flowing adjacent to the flooded air shaft and the West Branch Ompompanoosuc River [45 pp 67] Samples from both of these locations were analyzed to characterize the local range of variability of naturally occurring metals [6 p 48]

Surface water samples were collected from the West Branch Ompompanoosuc River to identify if a release occurred (Figure 2) [6 p 22 45 pp 1-5 9 14]

Background samples and release samples were similartypes of samples collected from the same environmental setting No precipitation events occurred while sampling in the West Branch Ompompanoosuc River [6 p 21] Streamflow in this river was observed to be moderate (presumed to be greater than 100 cfs) during the sampling effort [6 p 48]


Background Samples

The headwaters of Copperas Brook begin in Source 2 Based on this an upstream or background sample could not be collected from Copperas Brook Therefore background sample SW-09 was collected from an unnamed stream southeast of Tailings Pile No 1 This stream was selected because it had a flow rate similar to portions of Copperas Brook and did not appear to be impacted from historical mining operations The unnamed stream discharges into the ponded water on top of Tailings Pile No 1 The background sample was collected approximately 250 feet upstream of the confluence with the ponded water at Tailings Pile No 1 (Figure 2) [45 P 10]

Because of different flow rates background samples used for Copperas Brook could not be used to establish an observed release in the West Branch Ompompanoosuc River Therefore background samples SW-06 and SWshy05 were collected from the West Branch Ompompanoosuc River Two locations were sampled for metals analysis to characterize the local range of variability of naturally occurring metals Sample locations were selected approximately 25-50 feet upstream of the confluence between an unnamed brookflowmg adjacent to the air shaft and the West Branch Ompompanoosuc River (PPE2) (Figure 2) [45 pp 6-7]

Contaminated Samples

Surface water sample SW-07 was collected in Copperas Brook approximately 15 feet upstream of its confluence with the West Branch Ompompanoosuc River (Figure 2) Sample SW-07 was collected at a depth similar to the background sample [45 p 8] The sample location was upstream of a weir installed above the confluence Rocks and sediment at this location as well as the entire length of Copperas Brook were stained orange to red-brown This same orange to red-brown staining is visible throughout the drainage areas and materials at the Elizabeth Mine [45 p 8 6 pp 4243]

Surface water samples SW-08 and SW-11 were collected from the West Branch Ompompanoosuc River Locations were selected along the Rivers south bank in the vicinity of the confluence with an unnamed brook flowing adjacent to the air shaft Sample SW-08 was collected at the confluence Sample SW-11 was collected approximately 75-100 feet downstream of the confluence [45 pp 9 14] Rocks and sediment at the confluence were stained the same orange to red-brown color as evidenced in Copperas Brook Downstream of the confluence rocks andor sediment were also similarly stained [45 pp 9 14]

Surface water samples SW-02DUP-01 and SW-01 were collected from the West Branch Ompompanoosuc River Locations were selected along the Rivers south bank in the vicinity of the confluence with Copperas Brook Sample SW-02DUP-01 was collected at the confluence sample SW-01 was collected approximately 25 feet downstream of the confluence respectively Rocks and sediment at the confluence were stained the same orange to red-brown as evidenced in Copperas Brook This same orange to red-brown staining is visible throughout the drainage areas and materials at the Elizabeth Mine [45 pp 1-3 6 pp 4243] Downstream of the confluence rocks and sediment were also similarly stained [45 p 1]

An observed release by chemical analysis was not established for surface water samples SW-03 and SW-04 [13 p 7 56] Sample SW-03 was collected in the West Branch Ompompanoosuc River approximately 35 feet upstream of the confluence with Copperas Brook Sample SW-04 was also collected in the West Branch Ompompanoosuc River approximately 30 feet downstream of the confluence between the unnamed brook (adjacent to the air shaft) and the West Branch Ompompanoosuc River [45 pp 45]

Attribution

The ore deposit at the Elizabeth Mine is rich in iron-sulfide minerals [48 p 2] Initially the deposit was valued for iron and then pyrrhotite from which copperas (iron sulfate) was produced [20 pp 8 67] In the 1830s the deposit was mined for copper from chalcopynte (copper iron sulfide) A significant amount of chalcopynte was found disseminated in the pyrrhotite [20 pp 8 67] the primary minerals in ore and host rock and the secondary minerals that form during weathering of ore and tailings provide the source for metals and acidity in associated waters [48 p 2] Some of these minerals include sphalerite arsenopynte galena cobaltite and molybdenite Metals such as cadmium antimony arsenic and selenium are chemical components of these minerals [48 p 3]

Tailings Pile Nos 1 and 2 (Source 1) consist of processed mine tailings from copper mining operations during the 20th century Tailings Pile No 3 (Source 2) consists of mine waste and smelter waste generated from mining operations in the 19th century [48 pp 512] All of these piles are uncovered and exposed to weathering processes [6 pp 32-37] Copperas Brook flows over or through the tailings in each of the piles prior to being reshyrouted through a buried conduit in Tailings Pile No 1 [6 p 31] As precipitation comes into contact with the oxidized sulfide-nch minerals within the tailings sulfunc acid is produced and hydrogen ions are released thus lowering the pH of the tailings [30 pp 89] Consequently metals and sulfides within the piles are leached and acid mine drainage is produced [30 pp 824] This drainage enters Copperas Brook and carries dissolved metal concentrations to the West Branch Ompompanoosuc River [27 p 2 31 p 15 48 pp 12]

The air shaft that once provided ventilation for underground mining operations flooded when mining was abandoned [27 p 2] As water comes into contact with the ore and the host rock in the underground workings metals are leached and acid mine drainage is produced [30 p 24] This drainage flows upgradient through the air shaft and discharges onto the ground [31 p 19] This discharge flows overland approximately 35 feet and empties into an unnamed brook [45 pp 11-13] The brook is continuously fed by the acid mine drainage from the air shaft [25] The unnamed brook flows approximately 25 feet and discharges into the West Branch Ompompanoosuc River [45 pp 11-13]


Laboratory analysis of samples collected from Source Nos 12 and 3 detected the following aluminum arsenic barium chromium cobalt copper iron lead magnesium manganese mercury nickel potassium selenium sodium vanadium and zinc [14 p 14 15 p 10 24 App B Tab 6 Tab 7 pp 20-21]

Surface water analytical results from samples collected in Copperas Brook and the West Branch Ompompanoosuc River indicate the following metals with concentrations that satisfy observed release criteria aluminum chromium cobalt copper iron magnesium manganese nickel potassium selenium sodium and zinc

Acid mine drainage from the Elizabeth Mine is damaging Copperas Brook and has degraded the water quality and aquatic biology of the West Branch Ompompanoosuc River [29 p 1 30 pp 12]

Chemical Analysis - Sediment Samples

In October and November 1999 an EPA Contractor conducted sampling activities at the Elizabeth Mine site as part of the HRS field effort Sediment samples were collected by the EPA Contractor and submitted to a procured laboratory for total metals analysis The analysis was performed in accordance with the CLP ILMO 4 0 Statement of Work as modified by technical specification S99-RAC1-108 [6 p 27 14 pp 1-15 50 pp 1-22]

Analytical data from background sediment samples were used to determine background levels by chemical analysis Sediment analytical results from the background samples were compared to analytical data from the release samples to determine if observed release criteria for chemical analysis were met [1 p 51589 Tab 2-3] In addition information related to the site and sampling procedures such as soil type organic content environmental setting and sample handling and analytical procedures were considered in establishing similarity between background and release samples

Background Samples

Background sediment samples were collected from the streambeds of the unnamed stream southeast of Tailings Pile No 1 and from the West Branch Ompompanoosuc River (Figure 2) [45 pp 20 21 24 25] Release sediment samples were collected from the streambeds of Copperas Brook the West Branch Ompompanoosuc River and the unnamed brook adjacent to the air shaft [45 pp 15-19 22 23 26 29]

Copperas Brook originates at the base of Tailings Pile No 3 therefore background sediment samples were not collected in Copperas Brook [31 p 23] The streambed of every prospective sample location was visually impacted by orange to red-brown stains [6 p 43] The entire brook appears to be impacted by acid mine drainage [6 p 46] Background sample results from the unnamed stream were compared to analytical results of release samples from Copperas Brook

Background sediment samples were not collected in the unnamed brook adjacent to the air shaft The unnamed brook is likely intermittent at elevations above PPE2 [4 25 p 3] Below PPE2 the streambed was visually impacted by orange to red-brown stains [45 p 29] Background sediment sample results from the unnamed stream were compared to analytical results of the release sample from the unnamed brook

Unnamed Stream

The unnamed stream flows west-northwest and discharges into ponded water on top of Tailings Pile No 1 (Figure 2) [6 p 46] Background samples D00814 (SD-09) and D00813 (SD-10) were collected approximately 250 feet and 285 feet upstream of the confluence between the ponded water and the unnamed stream respectively [45 PP 24 25]

Two samples were collected from the unnamed stream to account for variability in background metal concentrations For each analyte the sediment sample with the highest concentration was used to establish background concentrations The streambed of the unnamed stream was not stained [6 p 47] The background locations appeared to be outside the area impacted by acid mine drainage and past mining operations [6 p 47]

Background samples D00814 (SD-09) and D00813 (SD-10) and release samples D00816 (SD-07) D00815 (SDshy08) and D01118 (SD-13) were collected from the same sample matrix (i e sediment) [45 pp 22-25 29 14 p 14 50 p 22] The soil type and organic content at each location appeared similar The soils primarily consisted of silty sand A significant organic content was not observed at any of the locations Leaves and twigs were more prevalent on the surface of the streambed at sample location SD-09 than SD-10 however soil types beneath the leaf matter were not rich in organic material [45 pp 22-25 29]

The flow rate in the unnamed stream appeared to be minimal during the sampling task [6 pp 46 47] According to the USGS the upper portion of Copperas Brook (between Tailings Pile Nos 2 and 3) tends to go dry during summer months [4] Streamflow measurements collected at the mouth of Copperas Brook between October 1998 and September 1999 indicate an average yet continuous flow rate of less than 1 cfs [25 pp 1-3] This data supports the characterization that the lower portion of Copperas Brook is a perennial body of water with a minimal flow rate [1 p 51613 Tab 4-13]


Sediment from the unnamed stream the unnamed brook and Copperas Brook appear to be similar based on soil type and organic content Streamflow in each of these bodies of water appears to be similar All sediment samples were collected similarly using stainless steel trowels and bowls [45 pp 22-25 29 4 25 pp 1-3]


The West Branch Ompompanoosuc River flows east at the base of Copperas Hill and empties into the Ompompanoosuc River [3] Dramagefrom the Elizabeth Mine site flows into the West Branch Ompompanoosuc River via Copperas Brook orthe unnamed brook adjacent to the flooded air shaft at the base of Copperas Hill [3 45 pp 11-136 p 44]

Background sediment samples D00818 (SD-05) and D00817 (SD-06) were collected in the West Branch Ompompanoosuc River (Figure 2) [45 pp 20 2114 pp 1415] Sample locations were selected approximately 25 and 50 feet upstream of the confluence between the unnamed brook and the West Branch Ompompanoosuc River respectively [45 pp 2021] Sediment samples from both of these locations were analyzed to characterize the local range of variability of naturally occurring metals [6 p 48] For each analyte the sediment sample with the highest concentration was used to establish background concentrations The streambed at the background locations in the West Branch Ompompanoosuc River was not stained The background locations appeared to be upstream of the area impacted by acid mine drainage and past mining operations [45 pp 20 21]

Sediment samples D00379(SD-01) D00378(SD-02) D00381 (SD-DUP-02) D00377(SD-03) D00376 (SD-04) and D00382 (SD-11) were collected from the West Branch Ompompanoosuc River to identify if a release occurred from the site (Figure 2) [45 pp 15-19 26 14 pp 13 15]

Background sediment samples and release sediment samples in the West Branch Ompompanoosuc River were collected from the same environmental setting [45 pp 15-21 26 3] The soil type and organic content at each location was similar The soils primarily consisted of fine to coarse sand few gravels and trace organics [45 pp 15-21 26]

Streamflow in the West Branch Ompompanoosuc River was observed to be moderate (presumed to be greater than 100 cfs) during the sampling effort [6 p 48] The West Branch Ompompanoosuc River is a perennial body of water [3]

Sediment from the background and release sample locations m the West Branch Ompompanoosuc River appeared to be similar based on soil type and organic content Streamflow at the background locations was similar to Streamflow at the release sample locations All sediment samples were collected similarly using stainless steel trowels and bowls [45 pp 15-21 26]

Sediment sample SD-07 was collected in Copperas Brook approximately 15 feet upstream of the confluence between the Brook and the West Branch Ompompanoosuc River The sample location was upstream of a weir at the end of the Brook (Figure 2) Rocks and sediment at this location were stained orange to red-brown and appeared to be impacted by drainage from the Elizabeth Mine [45 p 22] Sample SD-07 was collected at a depth similar to the background samples [45 pp 22 24 25]


Sediment sample SD-08 was collected in Copperas Brook just below the confluence with the east branch (Figure 2) Rocks and sediment at this location were stained orange to red-brown and appeared to be impacted by drainage from the Elizabeth Mine [45 p 23] Sample SD-08 was also collected at a depth similar to the background samples [45 pp 23-25]

Sediment samples SD-04 and SD-11 were collected from the West Branch Ompompanoosuc River Locations were selected along the Rivers south bank in the vicinity of the confluence with the unnamed brook that flows adjacent to the air shaft (Figure 2) Samples SD-04 and SD-11 were collected approximately 30 feet and 75-100 feet downstream of the confluence respectively Rocks and sediment at the confluence were stained orange to red-brown and appeared to be impacted by drainage from the air shaft Downstream of the confluence rocks andor sediment were visibly stained and still appeared to be impacted by drainage from the air shaft [45 pp 19 26]

Sample SD-13 was collected in the unnamed brook adjacent to the air shaft approximately 25 feet upstream of the confluence between the stream and the West Branch Ompompanoosuc River (Figure 2) [45 p 29] Sample results were compared to background concentrations detected in sediment samples from the unnamed stream southeast of Tailings Pile No 1

The air shaft provided ventilation for underground mining operations When mining was abandoned portions of the mine flooded [27 p 2] Water and acid mine drainage flow through the mine tunnels and discharge via the air shaft [27 p 2] The discharge flows overland approximately 35 feet and empties into the unnamed brook [45 pp 11-13] Precipitates (white and orange to red-brown) ponded water flooded forest floor decayed leaf matter and dead trees were observed below the air shaft [6 p 4545 pp 11-13]

Tailings Pile Nos 1 and 2 (Source 1) consist of processed mine tailings from copper mining operations during the 20th century Tailings Pile No 3 (Source 2) consists of mine waste and smelter waste generated from mining operations in the 191 century [48 pp 512] All of these piles are uncovered and exposed to weathering processes [6 pp 32-37] Copperas Brook flows over or through the tailings m each of the piles prior to being reshyrouted through a buried conduit in Tailings Pile No 1 [6 p 31] As precipitation comes into contact with the oxidized sulfide-nch minerals within the tailings sulfunc acid is produced and hydrogen ions are released thus lowering the pH of the tailings [30 pp 89] Consequently metals and sulfides within the piles are leached and acid mine drainage is produced [30 pp 824] This drainage enters Copperas Brook and carries dissolved metal concentrations to the West Branch Ompompanoosuc River [27 p 2 31 p 15 48 pp 12]

The air shaft which once provided ventilation for underground mining operations flooded when mining was abandoned [27 p 2] As water comes into contact with the ore and the host rock in the underground workings metals are leached and acid mine drainage is produced [30 p 24] This drainage flows upgradient through the air shaft and discharges onto the ground [31 p 19] This discharge flows overland approximately 35 feet and empties into an unnamed brook [45 pp 11-13] The brook is continuously fed by the acid mine drainage from the air shaft [25] The unnamed brook flows approximately 25 feet and discharges into the West Branch Ompompanoosuc River [45 pp 11-13]

4133 HUMAN FOOD CHAIN THREAT-TARGETS

The Elizabeth Mine is drained primarily by Copperas Brook its headwaters are located in Tailings Pile No 3 (Source 2) [27 pp 18 30 pp 20 2131 p 23] Copperas Brook flows into the West Branch Ompompanoosuc River According to a representative from the State Fishery Management District there is no information supporting the presence of fish in Copperas Brook [53] Metals in sediments acidic conditions habitat modifications loss of riparian vegetation and low dissolved oxygen levels from the tailings appear to have rendered Copperas Brook uninhabitable (i e non-support of aquatic biotahabitat) [7 pp 1-3] Therefore Copperas Brook is not considered a fishery for the purposes of this MRS package [21 pp 294-295]

The lower portion of the unnamed brook is primarily fed by drainage from the air shaft [25 pp 2 3] At elevations above the air shaft streamflow m the brook is likely intermittent [4 25 pp 2 3 3] Presumably the unnamed brook is not a fishery

Portions of the West Branch Ompompanoosuc River Ompompanoosuc River and the Connecticut River all support fish and are fished to some degree In both the West Branch Ompompanoosuc River and the Ompompanoosuc River fish are removed for human consumption although no production data are available The West Branch Ompompanoosuc River is stocked annually with brook trout The Ompompanoosuc River is stocked annually with rainbow trout brook trout and salmon [53]

According to a State of Vermont Assessment Report for the West Branch Ompompanoosuc River a portion of the River (from the Copperas Brook confluence to the Ompompanoosuc River confluence) does not support aquatic biota due to metals m sediments and acidic conditions from the tailings at the Elizabeth Mine [7 pp 1-3]

In July 1989 the US Army Corps of Engineers investigated the effects the Elizabeth Copper Mine has on fishery resources m the West Branch Ompompanoosuc River A fish community composition was determined as part of the study Results indicated that the fish community upstream of the Elizabeth Mine included longnose dace blacknose dace brook trout and slimy sculpm Downstream of the Copperas Brook confluence brook trout and longnose sucker were the predominant species with fewer populations of blacknose dace longnose dace slimy sculpm and brown trout [33 pp 10-11]

In addition to the fish community composition a study regarding levels of select metals m blacknose dace and river sediment from the West Branch Ompompanoosuc River was also conducted Samples were collected from four locations including areas upstream of the confluence with the air shaft and downstream of the confluence with Copperas Brook Twenty fish samples and one sediment sample were collected from each sampling station [33 pp 14-11 14] According to the fish community composition study blacknose dace ranged m length from 3 to 7 5 centimeters at locations upstream and downstream of the Elizabeth Mine [33 pp 5 11-13] Fish from each station were dissected rinsed and homogenized [33 p 4] Sample data from this study could not be used to document Level I concentrations for the Human Food Cham Threat because blacknose dace represent a common forage species in the river [33 p 4] Presumably forage species are not consumed directly by humans and are therefore not considered human food chain organisms [1 p 51620] Therefore portions of the West Branch Ompompanoosuc River fishery were scored for Level II concentrations based upon surface water and sediment samples

Copperas Brook is not a fishery [53] Sample data from Copperas Brook could not be used to establish Actual Contamination of a fishery for the Human Food Cham Threat

Surface Water Samples

In 1999 an EPA Contractor collected surface water samples from the West Branch Ompompanoosuc River Analytical data meets observed release criteria m five out of seven samples of surface water (Figure 2) [13 pp 7 8] An observed release was not established for surface water samples collected from locations SW-03 or SWshy04 [13 pp 7 8] A hazardous substance with a bioaccumulation potential factor value of at least 500 was not detected in the sample collected from location SW-11 The following surface water samples contain one or more hazardous substances with a bioaccumulation potential factor value of 500 or greater [2 pp B-6 B-17 B-20]

SWOFEnvironment-Targets

4 1 4 3 ENVIRONMENTAL THREAT - TARGETS

There are two PPEs for surface water drainage from the Elizabeth Mine PPE 1 is located in Copperas Brook at the base of Tailings Pile No 1 PPE 2 is located in unnamed brook adjacent to the air shaft (Figure 2)

The Elizabeth Mine is drained primarily by Copperas Brook its headwaters are located in Tailings Pile No 3 (Source 2) [27 pp 18 30 pp 20 21 31 p 23] From PPE1 Copperas Brook flows approximately 0 4 of a mile and empties into the West Branch Ompompanoosuc River [3 62 pp 12]

Underground shafts and tunnels extend from the open cuts to the West Branch Ompompanoosuc River An air shaft above the West Branch Ompompanoosuc River provided ventilation for underground mining operations [48 p 7] When mining was abandoned these shafts and tunnels flooded [27 p 2 31 p 19] Upflow from the air shaft discharges acid mine drainage to the ground surface where it becomes surface runoff [32 p 4 48 p 7] Drainage from the air shaft flows overland approximately 35 feet and enters an unnamed brook approximately 25 feet upstream of the West Branch Ompompanoosuc River (Figure 3) [45 pp 11-13]

Acid mine drainage from the Elizabeth Mine has degraded the water quality and the aquatic biology of Copperas Brook and the West Branch Ompompanoosuc River [30 pp 1 2] Metals in sediments low pH habitat modifications loss of riparian vegetation and low dissolved oxygen levels from the tailings appear to have rendered Copperas Brook uninhabitable (i e non-support of aquatic biotahabitat) [7 pp 1-3] According to the State of Vermont Assessment Report forthe West Branch Ompompanoosuc River the stretch of river between the Copperas Brook confluence and the Ompompanoosuc River confluence does not support aquatic biota due to acid mine drainage from the tailings at the Elizabeth Mine [7 pp 1-3]

Copperas Brook West Branch Ompompanoosuc River Ompompanoosuc River and the Connecticut River are State-designated areas for the protection or maintenance of aquatic life designated under Section 305(a) of the Clean Water Act as amended [1 p 51624 Tab 4-23 60]

The ponded water on Tailings Pile No 1 (Source 1) represents a flooded wetland and is classified as a palustnne system in the flat class [36] The water level in this wetland varies seasonably [48 p 15] This wetland type was not scored in the HRS scoring package because it was considered temporary it is not listed as an eligible HRS wetland [21 p A-22] Wetlands along the target distance limit were scored under Potential Contamination (Section 4 1 4 3 1 3 )


Level I concentrations were not scored because sufficient documentation regarding ecological-based benchmarks was not identified in SCDMS


Sediment samples were used to establish Level II concentrations The most distant Level II sample concentration is established at D00379 (SD-01) collected in the same area as surface water sample MALF07 (SW-01 )(Figure 2)

The Ompompanoosuc River flows at a rate of approximately 173 cfs at Gauging Station 01141500 [8 39 43 44 pp 12] This River represents a moderate to large stream based on the flow rate [1 p 51613 Tab 4-13] The drainage area for the Ompompanoosuc River is approximately 130 square miles [39]

There are no gauging stations in the Connecticut River within the 15-downstream mile target distance limit for the surface water pathway Gauging station 01138500 at Wells River Vermont is the most upstream station At this location the Connecticut River flows at a rate of approximately 3516 5 cfs [9] Gauging station 01156500 at Vernon Vermont is the most downstream station in the Connecticut River Streamflow at this station is approximately 8333 8 cfs based on USGS data for the drainage area and a mean annual runoff rate for the region [9] Water bodies with streamflow rates greater than 1000 to 10000 cfs are considered large streams to rivers [1 Tab 4-13 p 51613]

All steam flow calculations were based on average annual runoff values (inches) converted to flow per square mile (cfsmi2) For the eastern portion of Orange County Vermont a conversion factor of 1 33 cfs per mi2 was used [43 44 pp 12]

Appendix B Definitions of Potentially Vulnerable Environments1

Class I Ground Waters Ground waters that are highly vulnerable to contamination and are either (1) irreplaceable as a source of drinking water to a substantial population or (2) ecologically vital

Karst Terrain Areas where karst topography with its characteristic surface and subterranean features is developed as a result of dissolution of limestone dolomite or other soluble rock Characteristic physiographic features present in karst terrain include but are not limited to sinkholes sinking streams caves large springs and blind alleys

Seismic Impact Areas Areas where the probability is greater than or equal to 10 percent that the maximum horizontal acceleration in firm ground or rock at a particular site will equal or exceed 010 g (expressed as a percentage of the earths gravitational pull (g)) within a time period of 250 years Horizontal ground acceleration is defined as maximum change in velocity over rime relative to horizontal movement of the earths surface as measured at a particular point during an earthquake This parameter is used to calculate the acceleration values for any particular area and is derived from equations relating to the areas geology and its past seismicity

Unstable Terrain Areas capable of impairing the integrity of an engineered structure as a result of natural events or human activities Relevant natural events include but are not limited to localized ground subsidence differential settling collapse and slope failure sinkhole formation in karst terrains liquefaction and hydrocompaction Relevant human activities include but are not limited to construction operations flood controls ground water pumping injection and withdrawal resource extraction storm water drainage and seepage from human-made water reservoirs

Wellhead Protection Areas Areas designated by the states to protect wells in recharge areas of public drinking water supplies under authority of Section 1428 of the Safe Drinking Water Act

100-year Floodplain Any area that is subject to a one percent or greater chance of flooding in any given year from any source For riverine systems both the floodway and the floodway fringe are included in the 100-year floodplain
