BACKGROUND A. The United States of America (''United States"), on behalf of the Administrator of the United States Environmental Protection Agency ("EPA"), filed a complaint in this matter pursuant to Sections 106 and 107 of the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), 42 U.S.C. §§ 9606, 9607. B. . The United States in its complaint seeks, inter alia: (1) reimbursement of costs incurred by EPA and the Department of Justice for response actions at the Weyerhaeuser Company Plymouth Wood Treating Plant site in Martin County, North Carolina, together with accrued interest; and (2) performance of studies and response work by the defendant at OU-3 consistent with the National Contingency Plan, 40 C.F.R. Part 300 (as amended) ("NCP"). C. In accordance with the NCP and Section 12l(f)(l)(F) of CERCLA, 42 U.S.C. § 9621(f)(l)(F), EPA notified the State of North Carolina (the "State") on November 7, 2003, of negotiations with the potentially responsible party regarding the implementation of the remedial design and remedial action for the Former Chlorine Plant, and EPA has provided the State with an opportunity to participate in such negotiations and be a party to this Consent Decree. D. In accordance with Section 122(j)(l) of CERCLA, 42 U.S.C. § 9622(j)(l), EPA notified the United States Fish and Wildlife Service (US FWS) and the National Oceanic and· .Atmospheric Administration (NOAA) on November 7, 2003, of negotiations with the potentially responsible party regarding the release of hazardous substances that may have resulted in injury to the natural resources under Federal trusteeship and encouraged the trustees to participate in the negotiation of this Consent Decree: . E. The defendant that has entered into this Consent Decree ("Settling Defendant") does not admit any legal conclusions, fault or liability to the Plaintiff or to any other person or entity arising out of the transactions or occurrences alleged in the complaint, nor does it acknowledge that the release or threatened release of hazardous substances at or from OU-3 constitutes an imminent or substantial endangerment to the public health or welfare or the environment. As to others who are not parties, nothing contained in this Consent Decree shall constitute an admission by Settling Defendant of the facts and conclusions contained herein, and entry into this Consent Decree shall not constitute an admission by Settling Defendant of liability or a waiver of any right, cause of action or defense otherwise available to it. Except as specifically provided otherwise herein, Settling Defendant expressly reserves all rights, causes of action, and defenses available to it. F. In response to a release or a substantial threat of a release of a hazardous substance(s) at or from the Site, the Settling Defendant; commenced on March 24, 1998, a Remedial Investigation and Feasibility Study ("RIIFS") for the Site pursuant to 40 C.F.R. § 300.430. This RI/FS encompassed three source areas, including: (1) the Former Landfill No. 1, and the soils, groundwater, and surface water impacted by the Former Landfill No. 1, (2) the Former Chlorine Plant, and soils, sediments and groundwater impacted by that plant, and (3) the sediments and surface water contained in Welch Creek and associated wetlands. For the purposes of this Consent Decree, these three source areas will be considered three Operable Units ("OUs"), and the Former Chlorine Plant and the soils, sediments, and groundwater impacted by the Former Chlorine Plant, which is the subject of this Consent Decree, is termed "OU-3". • • G. The Settling Defendant completed the Remedial Investigation ("Rf') Report and the Feasibility Study ("FS") for OU-3 on June 24, 2003. H. Pursuant to Section 117 of CERCLA, 42 U.S.C. § 9617, EPA published notice of the completion of the FS and of the proposed plan for remedial action for OU-3 on July 12, 2003, in a major local newspaper of general circulation. EPA provided an opportunity for written and oral comments from the public on the proposed plan for remedial action .. A copy of the transcript of the public meeting is available to the public as part of the administrative record upon which the Regional Administrator based the selection of the response action. I. The decision by EPA on the remedial action to be implemented for OU-3 is embodied in a final Record of Decision ("ROD"), executed on September 29, 2003, on which the State has given its concurrence. The ROD includes a responsiveness summary to the public comments. Notice of the final plan was published in accordance with Section 117(b) of CERCLA. J. Based on the information presently available to EPA, EPA believes that the Work wili be properly and promptly conducted by the Settling Defendant if conducted in accordance with the requirements of this Consent Decree and its appendices. K. Solely for the purposes of Section 113(j) of CERCLA, the Remedial Action selected by the ROD and the Work to be performed by the Settling Defendant shall constitute a response action taken or ordered by the President. L. The Parties recognize, and the Court by entering this Consent Decree finds, that this Consent Decree has been negotiated by the Parties in good faith and implementation of this Consent Decree will expedite the cleanup of OU-3 and will avoid prolonged and complicated litigation between the Parties, and that this Consent Decree is fair, reasonable, and in the public interest.

IfEPA agrees that the delay or anticipated delay is attributable to a force majeure evertt, the time for performance of the obligations under this Consent Decree that are affected by the force majeure event will be extended by EPA for such time as is necessary to complete those obligations. EPA will consider extending the delay of the performance of the obligations affected by the force majeure event by not less than the actual duration of the delay caused by the force majeure event. An extension of the time for performance of the obligations affected by the force majeure event shall not, of itself, extend the time for performance of any other obligation. If EPA does not agree that the delay or anticipated delay has been or will be caused by a fo~ce majeure event, EPA will notify the Settling Defendant in writing of its decision. If EPA agrees that the delay is attributable to a force majeure event, EPA will notify the Settling Defendant in writing of the length of the extension, if any, for performance of the obligations affected by the force majeure event. 61.

Site Name and Location Fonner Chlorine Plant Area-Operable Unit 3 Weyerhaeuser Company Plymouth Wood Treating Plant Site Martin County, North Carolina EPA ID# NCD991278540 Statement of Basis and Purpose · This decision document presents the selected remedial action for the Former Chlorine Plant Area of the Weyerhaeuser Company Plymouth Wood Treating Plant Site, Martin County, North · Carolina, chosen in accordance with the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), as amended by the Superfund Amendments and Reauthorization · Act of 1986 (SARA) and, to the extent practicable, the National Contingency Plan (NCP). This decision is based on the administrative record file for this Site. The State of North Carolina concurs with the selected remedy. C. Assessment of the Site The response act.ion selected in this Record of Decision is necessary to protect the public health or welfare or the environment from actual or threatened releases of hazardous substanc~s into the environment. Description of the Selected Remedy The Weyerhaeuser Company Wood Treating Plant Site is comprised of 4 areas of concern which are being investigated separately in focused Remedial Investigations and Feasibility Studies. The 4 areas are Landfill No. 1, the Former Chlorine Plant, Welch Creek and the Roanoke River. This remedy addresses the threat posed by the Fonner Chlorine Plant Area of the Weyerhaeuser Site. Mercury contamination in soil in the immediate area of the Former Chlorine Plant is the major threat to human health . .md the environment: The major components of the selected remedy include: • • • • A Barrier Wall Containment system for contaminated soils largely within the footprint of the Former Chlorine Plant building; Shallow Target Area Excavations of contaminated soils; A Surface Cap Containment system; · Groundwater monitoring; and Fonner Chlorine Plant Area of the Weyerhaeuser Company Site . Record 'or Decision Manin County. NC September, 2003 . • • • Institutional Controls for land and groundwater use. E. Statutory Determinations The selected remedy is protective of human health and the environment, complies with Federal and State requirements that are legally applicable or relevant and appropriate to the remedial action, and is cost-effective. The remedy for the Former Chlorine Plant Area does not satisfy the statutory preference for treatment as a principal element because the remedy for the Site is containment. However, the excavation of the Target Areas soils may result in treatment if contaminant levels exceed a threshold level. ,- Because this remedy will result in hazardous substances, pollutants, or contaminants remaining on-site above levels that allow for unlimited use and unrestricted exposure, a statutory · review will be conducted within five years after initiation of remedial action to ensure that the remedy is, or will be, protective of human health and the environment.

NC September. 2003 • vi • • A. Site Name, Location and Description The Weyerhaeuser Company Wood Treating Plant Site is an active wood and paper products manufacturing facility located just outside of the city limits of Plymouth, Martin . County, North Carolina. The CERCLIS Site ID number is NCD991278540. The EPA has the enforcement lead at the Site, with support from the North Carolina Department of Environment and Natural Resources (NCDENR). EPA plans to negotiate a Consent Decree with the Responsible Party to conduct and pay for the cleanup at the Site: · · Cu_rrent operations at the Site include the production of fluff paper, paper, paperboard and finished lumber. Weyerhaeuser has been the owner/operator of this facility since 1957, after merging with the K.ieckhefer-Eddy Corporation, which began operation at the site in 19)7) The facility is located on approximately 2,400 acres, about 1.5 miles west of the town of Plymouth. The Former Chlorine Plant Area is approximately 3 acres in size, located adjacent to the Roanoke River in an active manufacturing area of the facility. A steel sheet-piling seawall (bulkhead) forms the entire northern boundary with the River in this part of the facility. The area is primarily covered with asphalt and concrete pavement. Figure A-1 shows the approximate location of the Fonner Chlorine Plant Area at the facility, and the size of the study area. B. Site History and Enforcement Activities The Fonner Chlorine Plant was built in 1951 and operated until 1968. Operations involved the production of chlorine and sodi11m hydroxide from salt brine. Twelve mercury cells, containing metallic mercury, were used in the production process. Process equipment was removed from the Former Chlorine Plant building from 1968-1978. The building was then used for storage and equipment maintenance until 1984. The building was demolished in 1986 and 1987. In 1992, the building slab, footings, a U-shaped concrete drain (the Central U-drain), tank foundations and surrounding soil down to the water table (to approximately 4 feet) were removed. The excavation was backfilled with soil and concrete and paved with asphalt. Soil samples were collected from the base of the excavation at the completion of the soil removal. Mercury concentrations in the soil not excavated were as high as 9,520 mg/kg. An additional U- shaped drain (the Eastern U-drain) was identified during the Remedial Investigation planning. A Special Notice Letter was sent to Weyerhaeuser ComTJany by the EPA on November 19, 1997, notifying them of potential liability, as defined by Section 107 (a) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended, that Weyerhaeuser may have incurred with respect to the Site. The Special Notice Letter outlined four areas on, and adjacent to, the facility property which, following initial investigation by EPA and the NCDENR, were documented to have caused a release or the threat of a release of hazardous substances, pollutants or contaminants. The four areas are: I) The Landfill No. 1 Area; 2) The Former Chlorine Plant Area; 3) Welch Creek; and 4) The Roanoke River ..

The Remedial Investigation/Feasibility Study for the Landfill No. 1 Area, The Former Chlorine Plant Area and Welch Creek were covered under the terms of the AOC and the attached Statement of Work (SOW). The Roanoke River is being investigated as a separate Operable Unit by the EPA using Superfund funding. A ROD was issued for the Landfill No. 1 Area on September 19, 2002. On August 18, 2003 EPA and Weyerhaeuser entered into a Consent Decree for the RD/RA for the Landfill No. 1 Area. C. Community Participation Pursuant to CERCLA Sections !13(k)(2)(B)(i-v) and 117, the RI/FS Report and the Proposed Plan for the Site were released to the public for comment on June 30, 2003.· l)lese documents were made available to the public in the administrative record located in an information repository maintained at the EPA Docket Room in Region IV and at the Washington County Public Library in Plymouth, North Carolina. The notice of the availability of these documents was published in the Roanoke Beacon, Plymouth North Carolina, on July 2, 2003 A pubic comment period on the documents was held from July 2, 2003 to August I, 2003. A copy of the notice and the Proposed Plan Fact sheet . were mailed to the Site mailing list which contains names of community members and interested parties. In addition, a public meeting was held on July 10, 2003. · At this meeting, representatives from EPA answered questions about the Site and the remedial alternatives under \X :,~· consideration. Meetings with city and county officials were also hdd. Other community relations activities included: • • • Development of a community relations plan .

Scope and Role of Operable Unit within Site Strategy Because of the geographic separation of the three areas, and the differences in the type of contamination present and the media impacted, individual RI/FS work and reports have been prepared for each of the three areas identified in the AOC. These focused investigations were conducted in order to ·streamline the investigation and remedy selection process. EPA plans to issue a ROD for each of the three areas of the site. The Roanoke River is being investigated by EPA using Superfund funding, and is designated as Operable Unit 2. The Operable Unit designations given to each area are: · Operable Unit I: Landfill No. I Area; Operable Unit 2: Roanoke River . Operable Unit 3:. The Former Chlorine Plant; and Operable Unit 4: Welch Creek. E. Site Characteristics 1. Conceptual Site Model The Remedial Investigation for the Former Chlorine Plant Area began with the development of an RI Work Plan, and a Conceptual Site Model. The Conceptual Site Model formed the basis for the investigation and risk assessment for the Former Chlorine Plant Area. The Conceptual Site Model for the Former Chlorine Plant Area is based on characteristics of the waste sources, the contaminants of potential concern (COPCs) for each affected environmental medium, and the migration and transport potential of the constituents to potential receptors. The primary original source of releases were the Former Chlorine Plant mercury cells and underdrain system. Surface and subsurface soil contamination is transported through precipitation to groundwater, and through volatilization and dust to the atmosphere. Groundwater contaminated with mercury eventually discharges downgradient to the Roanoke River immediately adjacent to the Former Chlorine Plant. The Conceptual Site Model for the Former Chlorine Plant Area is shown in Figure E-1. 2. Site Setting The Weyerhaeuser facility is located in a low-lying area neai-the confluence of Welch Creek and the Roanoke River. In general, the area comprises flat, low-lying terrain typical of the Tidewater region within the Coastal Plain Physiographic Province of North Carolina. At portions of the facility east of Welch Creek, ground surface elevations rise to 30 to 40 feet above mean sea level. The Former Chlorine Plant Area is at an elevation of approximately 8 feet, generally within the 5-foot to IS-foot elevation range typical for the region.

This results in significant fork lift and semi-truck traffic. Other structures in the area include storage sheds, a raw materials storage pad (drums) in the Former Chlorine Plant building footprint, a bank of the facility's cooling towers to the north adjacent to the River, and the former polycoater building to the west (now used for paper roll storage). 3. Regional Geology and Hydrogeology The geology in the region generally consists of a wedge of elastic sediment and marine limestone that thickens from west to east. The sediment consists of sand, silt, and clay. The sand is deposited in poorly connected bodies that may have only a limited horizontal and vertipal extent. However, on a regional scale, differences in the frequency of occurrence and th~ interconnection of the sand bodies are sufficient enough to distinguish regional aquifers from regional aquitards. The shallowest unit is the Quaternary-age surficial aquifer. It consists of fine sand, silt, clay, and peat that form a unit of less than 50 feet in thickness. Sand typically makes up greater than 70 percent of the unit in the Plymouth, North Carolina, area. Beneath the surficial aquifer is the Yorktown confining unit. These Pliocene-age marine deposits typically consist of up to 50 feet of clay and sandy clay, with occasional beds of fine sand or shells. In the Plymouth, North Carolina Area, the confining unit is reported to be about 40 feet thick. The Yorktown aquifer is immediately beneath the confining clay. It consists of fine sand, silty and clayey sand, and clay with shells and shell beds throughout the aquifer. From 70 to 80 percent of the aquifer is sand in the Plymouth, North Carolina, area. The confining unit of the Pungo River Formation is composed of Miocene-age clay from the lowermost Yorktown Formation and the top of the Pungo River Formation. The unit is typically more than 90 percent clay and averages 55 feet in thickness. The Pungo River aquifer below the clay is only about 10 feet thick near Plymouth, North Carolina. The Pungo River aquifer is separated from the Eocene-age Castle Hayne aquifer by the thin, and in some areas discontinuous, Castle Hayne confining unit. Where present, the Castle Hayne confining unit consists of clay and sandy clay. The Castle Hayne aquifer is composed predominantly of loose consolidated to hard (recrystallized) limestone, fine to coarse carbonate sand, and marl (clayey limestone). Limestone dominates the lithology in the top third to the top half of the aquifer, while sand dominates in the lower aquifer. The elevation of the aquifer below Plymouth, North Carolina, is reported to be Former Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision Martin County, NC September, 2003 6 • • about -130 feet. This is the most productive aquifer in North Carolina, with an average hydraulic · conductivity of 6.5 x 104 ft/s. At least five other confining/aquifer units have been identified below Plymouth, North Carolina. The deeper units are of little relevance because the Castle Hayne aquifer is the regional water supply aquifer below the Site. 4. Area Ground Water Use The majority of the Weyerhaeuser facility process water is obtained from the Roanoke River. Historical records indicate that as many as 30 water supply wells have been drilled on the Weyerhaeuser facility since 1937. Of the 19 wells not currently in use, construction . documentation for five indicates that well intakes were between 113 to 160 feet in depth: These depths indicate that the Castle Hayne aquifer was the source of water for the wells. All nineteen wells were properly abandoned. Water supply wells currently in use obtain their water from the Castle Hayne aquifer. There are no private water supply wells within l mile of the Former Chlorine Plant. It is estimated that about 330 people may be served by private wells within the three mile radius of the facility and south of the Roanoke River. Approximately 2.7 square miles of the area within the three mile radius are served by public water service from the City of Plymouth, and 4.3 square miles are part of the Weyerhaeuser facility. Private wells typically draw water from depths of 100 to 200 feet, within the Castle Hayne aquifer. The nearest private well is about l. I miles to the south of the Former Chlorine Plant. This well is reportedly 160 feet deep and is likely completed in the Castle Hayne aquifer. Regional ground water flow in the aquifer is from west to east, therefore, the nearest well to the Former Chlorine Plant is not downgradient of the plant. There is a cluster of homes to the southeast that is just over a mile from the facility. This area and the remaining residential areas are also not downgradient from the site. The City of Plymouth operates four public water supply wells just outside the 3-mile radius of the facility. The water supply system services approximately 5,900 people. The city system includes four wells located to the east of the plant site. The wells are from 115 to 1.85 feet deep, within the Castle Hayne (and possibly Pungo River) aquifers. Regionally, the general horizontal direction of groundwater flow within these formations is west to east, placing the City wells not downgradient of the landfill. 5. Remedial Investigation Field Work The RI field work at the Former Chlorine Plant Area was completed during two mobilizations, conducted from February to May of 1999. · Fonner Chlorine Plant Area of the Weyerhaeuser Company Site Rec~rd of Decision Martin County, NC September, 2003 7 • • Samples were assigned a unique alpha-numeric sample descriptor identifying the study area; media types; sample number; and, in certain instances, sample depth. The relevant study area descriptors.for the Former Chlorine Plant Area are as follows: • CP=Former Chlorine Plant • PW=Pore Water • SD=Sediment • SS=Surface Soil • SB=Subsurface Soil • PZ=Piezometer The sampling locations for the RI are shown on Figure E-2. Remedial Investigation site characterization. activities included soil, groundwater and near -shore sediment sampling. Specifically, the sampling efforts included the collection of 3 surface soil samples, the advancement of 23 soil borings to various depths, the installation of 32 on-shore monitoring wells and 11 temporary mini-piezometers in the river along the bulkhead, the advancement of 18 sediment thickness probes, and the collection of 10 sediment core sampl.es and three pore water samples. Samples were analyzed primarily for mercury. Additional analyses were conducted to quantify the presence of methyl mercury and bioassay indicators, to assess leachability, and to define inorganic constituents that may impact mercury treatment. This information in conjunction with historical data was used to evaluate the nature and extent of the constituents of concern. 6. Contaminant Distribution a. Soil Surface soil (to depths of 2 feet) was sampled in the limited unpaved area along the bulkhead. Total mercury was detected in only one of the three surface samples, at a total mercury concentration of 7 .3 mg/kg. The highest concentrations of mercury in the subsurface soil below the pavement were · coincident with the former building footprint and associated U-drains. Total mercury concentrations ranged from <0.04 to 45,800 mg/kg. Flecks and beads of metallic mercury were observed in soil samples from directly below the building footprint to a depth of 42 feet below ground surface, and are likely present as a result of leaks from the historical building drains.

Additionally, most of the concentrations greater than 100 mg/kg are within the building footprint, typically below the former mercury cell sumps and associated U-drains. The RI concluded that approximately 95 percent of the mercury mass is associated with concentrations above 100 mg/kg, and approximately 98 percent of the mercury containing soil is located above 26 feet below ground surface. Methyl mercury represents less than I percent of the total mercury in the subsurface soil tested.

Groundwater Of the 29 monitoring wells which were installed in the immediate area of the Former Clarine Plant, the North Carolina Maximum Acceptable Concentration (_NCMAC) for mercury in groundwater of 1.1 µg/kg was exceeded at six locations. In general, the highest mercury concentrations were observed at the water table beneath the former mercury cell room and U- drain system. The six monitoring wells with concentrations of mercury above the NCMA.C were shallow wells within the Former Chlorine Plant building footprint or immediately downgradient. Lower concentrations were measured in deeper samples, from the middle alluvial aquifer and from the marine sand. None of the groundwater samples collected from the deeper wells exceeded the NCMAC. The mercury-containing groundwater is in direct contact with the mercury-containing soil located within the alluvial aquifer, which extends from approximately 4 to 40 feet below the ground surface. Mercury concentrations decrease by an order of magnitude approximately 50 feet from the Former Chlorine Plant footprint and are at or below the NCMAC within 50 feet to the east and west of the footprint area. Total mercury concentrations from 13 monitoring wells at the water table ranged from 0.002 µg/kg to 116 µg/kg. Methyl mercury was quantified in selected groundwater samples at concentrations averaging 0.0 to 2 percent of the total mercury concentrations. The results of groundwater sampling during the RI are presented in Table E-3. c. Sediment Sediment core samples were collected at 10 locations within the Roanoke River adjacent to the Former Chlorine Plant Area. The cores were divided into four samples, with three samples evenly spaced in the upper soft sediment, and with the deepest sample coming from the underlying alluvial aquifer sand. Total mercury concentrations ranged from <0.05 mg/kg to 291 mg/kg. The thickness of soft sediment ranged from 4.2 feet to 13.9 feet, with an average depth of 10.1 feet. The areal distribution of the mercury in sediment does not directly correspond to the locations of the historical drains from the Former Chlorine Plant. The highest mercury concentrations were found over 250 feet upstream of the central discharge, at depths of approximately 8 feet within the-soft sediment column. Lower concentrations were found at all locations in the overlying sediment, providing evidence of continuing deposition of material with less mercury over time. -There was an area of buried sediment (depths of 9 to 10 feet) with mercury concentrations between 10 and 70 mg/kg that is adjacent to the bulkhead and downstream of the central and eastern historical U-drains. Possible hypotheses for the areal distribution of mercury in the sediment are resuspension and deposition of sediment due to constructiori activities related to the bulkhead extension, and/or due .. to historical barge loading oper~tions that occurred along the bulkhead near Fonner Chlorine Plant Area of the Weyerhaeuser Company Site Record of Dei:ision · Martin County, NC September, 2003 16 ··---·-----• • the Fonner Chlorine Plant. The vertical distribution of mercury was also variable across the area sampled. With the exception of the core sample collected at CPSD-06, the highest concentrations of mercury were quantified in soft sediment from either the second or third depth collected. One possible explanation for the vertical mercury profile detected during the RI is the deposition of clean sediment over these areas in the 30+ years since the Fonner Chlorine Plant ceased operations. Methyl mercury concentrations in sediment were not found with the highest total mercury concentrations. A higher percentage of methyl mercury compared with total mercury occurred in the upper one or two sample depths. However, the actual concentration of methyl mercury is generally proportional to the total mercury, ie: samples with higher mercury leyels also had higher methyl mercury levels. The percent of mercury that is present as methyl mercury in the sediment of the Roanoke River is at the low end of literature reported values for marine and estuarine sediment. Although methylation of mercury typically takes place in the top layers of sediment, this was not what was found during the RI. The conclusion presented in the RI was that the methylatioh of the mercury occurred historically, and like the sediments containing higher mercury concentrations, the sediment was then covered through burial. Mercury and methly mercury concentrations detected in Roanoke River sediment during the RI are presented in Table E-4.

Contaminant Fate and Transport The potential routes of migration from the various media in the Fonner Chlorine Plant Area are as follows: • Migration of mercury from surface soil to surface water • Volatilization of mercury from surface soil to air • Migration of mercury from subsurface soil to groundwater • Discharge of groundwater containing dissolved mercury into the Roanoke River The potential for these routes of migration to be completed and the details associated with them are'discussed in the following sections. The potential migration of mercury containing sediments downstream within the Roanoke River is being assessed as part of the Roanoke River Remedial Investigation, Operable Unit-2. 1. Surface Soil The Fonner Chlorine Plant Area is mostly covered with asphaltic concrete pavement and concrete. The covering reduces run-off, volatilization to the air and leaching from soil to groundwater, Uncovered soil is present near the bulkhead, where a small grass-covered strip is located adjacent to the bulkhead. Mercury was detected at one surface soil sample taken during the RI at 7-3 mg/kg, and previous sampling detected mercury levels as high as 59.8 mg/kg. The potential routes of migration from the grass covered strip are through surface water runoff and volatilization .. Surface water runoff is not likely to contain significant amounts of mercury because the ground surface is flat, the soil is sandy, and the mercury levels present in surface soil are low. In addition, significant volatilization of mercury from the soil is not expected. Since the mercury in soil has been present for decades, any elemental mercury (the source of greatest volatilization potential) would have long since volatilized. Also, since the levels of total mercury in the soil are low, this would not be a significant source. 2. Subsurface Soil to Groundwater Groundwater flow patterns beneath the Fonner Chlorine Plant are complex due to the presence of two mounds in the water table possibly created by leakage from a cooling tower used in the present manufacturing operations. In addition, there are numerous stonn water drains and process water drains in the area of the Former Chlorine Plant. The highest concentrations of total mercury in groundwater are present in the vicinity of . . Fonner Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision Martin County. NC September, 2003 21 ~. -~· .. ·. ;,.-:;::-;:,::--1. ~..:,~--:· .: • • the high soil concentrations below the former mercury cells and associated U-drains. As groundwater flows through these high concentrations of mercury in the soil, the mercury is leached from the soil and dissolves in the groundwater. Dissolved mercury is then earned through the aquifer with the groundwater flow. The potential leaching effect was confirmed · during the RI by using a Modified Synthetic Precipitation Leaching Procedure. The results are shown in Figure F-1. As presented in the graph, the total mercury in the "leachate" increases with increasing mercury concentration. Small beads of elemental mercury were observed in saturated soil beneath the center of the Former Chlorine Plant Area. Given the low water solubility of elemental mercury, this mercury could serve as an ongoing source of dissolved mercury to the groundwater. 3. Groundwater to the Roanoke River Groundwater originating beneath the Former Chlorine Plant travels in several directions as follows: • To the north and west, toward the bulkhead and the Roanoke River • To the south-southeast as a result of the mound near the cooling towers, eventually discharging to the Roanoke River to the north, due to the influence of regional groundwater flow. Vertical hydraulic gradients beneath the river along most of the bulkhead are upward, therefore, groundwater flowing northward may be entering the Roanoke River through leaks in the sheet pile bulkhead. This is possible due to the age and intended design of the bulkhead. · Groundwater flowing to the south-southeast discharges to the Roanoke River to the east of the Former Chlorine Plant Area, but this full migration route has not been defined. An estimate of the mercury flux from the Former Chlorine Plant Area was made during the RI using groundwater flow data and chemistry data. The flow system was divided into three parts on the basis of hydraulic conductivity: the shallow alluvial aquifer, the deep alluvial aquifer, and the marine sand. The combined mass of mercury discharging from the Former Chlorine Plant Area is estimated to be 0.012 pounds per year. There is significant uncertainty in the calculation due to oversimplified assumptions. Applying an uncertainty factor of± 10 provides a range of 0.0012 to 0.12 pounds per year. · The potential discharge of mercury to the Roanoke River from the Former Chlorine Plant was also evaluated on a concentration basis. Using an assumption that there is no mercury in the river upstream of the mill, and the Former Chlorine Plant groundwater flux is the only source, results in concentrations of 0.000000 I µg/L to 0.0000 I µg/L: These concentrations are 0.0009 to 0.09 percent of the North Carolina surface water quality standard of0.012 µg/L.

Current and Potential Future Land and Resources Uses The Former Chlorine Plant Area is located within the property boundary of the active Weyerhaeuser manufacturing facility. The plant is occupies approximately 2,400 acres located 1.5 miles from the Town of Plymouth, North Carolina. The Weyerhaeuser facility is expected to remain an active industrial facility in the future, and site access is controlled by complete perimeter fencing and full time security. Shallow groundwater in the vicinity of the Former Chlorine Plant is not currently used, and is not expected to be used, as a potable water source. However, the State of North Carolina considers all groundwater to be potentially potable. The Weyerhaeuser facility is located immediately adjacent to the Roanoke River: approximately 7 miles from the river's confluence with Albemarle sound. ·The river is used for recreational fishing and boating. Drinking water is not obtained from the surface water of the Roanoke River downstream of Weyerhaeuser. A national wildlife estuary is located across the River on Huff Island, and down river near the Albemarle sound. H. Summary of Site Risks The Baseline Human Health Risk Assessment and the Baseline Ecological Risk Assessment present the results of comprehensive risk assessments that addresses the potential threats to public health and the environment posed by the Site under current and future conditions, assuming that no remedial actions take place, and identifies the contaminants and exposure pathways that need to be addressed by the remedial action. 1. The Baseline Human Health Risk Assessment The Baseline Risk Assessment consists of the following sections: identification of chemicals of potential concern; exposure assessment; toxicity assessment; and, risk characterization. All sections are summarized below. a. Chemicals of Concern (COCs) The first step involved in the human health risk assessment process is selection of COCs. The COC selection identifies site-related chemicals that are present at concentrations that could result in potential adverse effects on human health. For the purpose of the baseline risk assessment, the COCs for human health, are mercury and methyl-mercury in soil and groundwater. Table H-1 presents a summary of the chemicals of concern and their detection in environmental media at the Former Chlorine Plant.

The exposure assessment is finalized with the estimate of the daily dose of COCs to which receptors may be exposed. The objective of the exposure assessment is to estimate the type and magnitude of potential exposures to COCs in environmental media associated with the Fonner Chlorine Plant Area. The exposure assessment for the Fonner Chlorine Plant Area follows the guidance in Risk Assessment Guidance for Superfund (RAGS) (EPA, 1989) and addresses the following: • • • Characterization of the exposure setting Identification of migration and exposure pathways Quantification of exr')sure Characterization of Exposure Setting The location and setting of the Fonner Chlorine Plant Area was presented earlier. As a component of characterizing the exposure setting for the Fonner Chlorine Plant Area, potential human rec_eptors and their expected types of exposure to the constituents present at the site were identified for.current and hypothetical future land use scenarios. These potential human Fonner Chlorine Plant Aiea of the Weyerhaeuser Company Site Record of Decision · Martin County, NC September, 2003 25 • • receptors represent those segments of the population most likely to come into contact with the COCs present in environmental media at the Former Chlorine Plant Area. Given the location of the Former Chlorine Plant Area human populations that may potentially be exposed to COCs under the current land use scenario are limited to the industrial worker and the construction worker. Fencing, and extensive facility security, eliminated the potential trespasser scenario. Shallow groundwater in the vicinity of the Former Chlorine Plant is not currently used, and is not expected to be used, as a potable water source. Therefore, potential groundwater ingestion pathways are considered incomplete for all receptors under consideration for current land uses, and as such, were not quantitatively evaluated in the risk assessment for those receptors. Even though shaUow groundwater is not used currently as a potable source and is · unlikely to be accessible for future use, the shallow groundwater in the vicinity of Former . Chlorine Plant Area is considered potable by the State of North Carolina. '• Identification of Migration and Exposure Pathways The conceptual site model for Former Chlorine Plant Area ( See Figure E-1) is based on characterization of waste sources, the COCs for each affected environmental medium, and the migration and transport potential of this constituent to potential receptors. An exposure pathway is the means by whi'ch a constituent moves from a source to a receptor. A completed exposure pathway has the following elements: 1. Constituent Source-The primary remaining known sources of site-related constituents in environmental media in the Former Chlorine Plant Area is mercury and methyl-mercury in soil and groundwater. 2. ' Mechanism for constituent release and environmental transport medium -The potential constituent release and transport pathways relevant to human health at the Former Chlorine Plant Area are as follows:· • • • Mercury and methyl-mercury in surface and subsurface soils that can migrate to groundwater; Discharge of groundwater containing ,nercury and methyl-mercury to the sediments and surface water of the Roanoke River; and Mercury accumulation in sediment from grouridwater discharge . 3. Feasible route of potential.exposure-Completed exposure pathways are the means by which potentially exposed populations (receptors) come into contact with site-related COCs. The completed exposure pathways Former Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision Martin County, NC September, 2003 26 • • evaluated under current land use scenarios for potential human receptors at the Former Chlorine Plant Area were as follows: • Industrial worker exposure (ingestion, dermal contact, inhalation) to mercury in uncovered surface soil • Incidental construction worker exposure (ingestion, dermal contact, inhalation) to mercury in subsurfac·e soil and dermal contact with groundwater. Quantification of Exposure The potential exposure to site-related COCs for each receptor is represented by "a''chronic daily intake (CDI). The CDI for an individual receptor is estimated from the exposure point concentration of each COC in each environmental medium. Exposure Point Concentration Consistent with Region 4 Supplemental Guidance (EPA, 1996), the exposure point concentrations used for estimating CD Is are the lesser of the maximum concentration for each · COC or the 95 percent upper confidence limit (95% UCL) of the mean concentration assuming a log-normal distribution of the data set. A value equivalent to one-half the Quantitation Limit · was used in the exposure point concentration calculations for constituents reported as not detected. The exposure point concentrations for the COCs from the various environmental media are presented in Table H-2.

The CD!s for COCs at the Former Chlorine Plant Area were calculated to represent both the RME and the potential average or central tendency exposure. The RME doses are defined as the "maximum exposure that is reasonably expected to occur at the site" (EPA, 1989). The average or central tendency exposure doses are defined as representing more typical exposures that are based on 50th percentile exposure estimates. The exposure variables used to calculate the CDI for each potential receptor for both the RME and the potential average or central tendency exposure are outlined in Table H-3. The exposure point concentration relied upon in both the RME and central tendency risk calculations is conservative in that it represents the 95% UCL for each media.

Toxicity Assessment There are two purposes of the toxicity assessment: first, to review available information on the potential adverse effects that may result from exposure to the COPC; and second, to quantify the relationship between exposure to these constituents and the likelihood of potential health effects. Toxicity reference values (TRVs) for the COPCs were taken from Integrated Risk Information System (IRIS) and the Health Effect Assessment Summary Table (HEAST). Toxicity Information for Non-carcinogenic Effects EPA's preferred (EPA, 1996) toxicity value for evaluating non-carcinogenic effects resulting from chemical exposure is the chronic reference dose (RID). The chronic RID is an estimate of a daily exposure level for the human population (including sensitive populac\C>ns) that should not cause an appreciable risk of harmful effects during a lifetime of exposure. For the Former Chlorine Plant Area baseline human health risk evaluation, mercury and methyl mercury were quantitatively evaluated for non-carcinogenic health effects. Oral RIDs (RIDO) are published exposure dose estimates derived from ingestion-based studies. RIDO values were used to estimate the potential hazards associated with the incidental ingestion pathway and with modification, the dermal contact pathway. Inhalation RIDs (RIDI) are published exposure dose estimates derived from inhalation based studies and were used to estimate the potential hazard for the inhalation pathway. Toxicity information for the oral route is not available for elemental mercury and as such, a quantitative estimate of risk through oral or dermal pathways cannot be estimated. The available toxicity values for mercuric chloride,(the soluble chloride salt of mercury) were evaluated for use as a surrogate. Table H-4a and H-4b present a summary of the available quantitative toxicity information.for elemental mercury, mercuric chloride, and methyl mercury for the estimation of hazard through incidental ingestion, dermal contact, and inhalation exposure pathways.

As a result, incremental carcinogenic risk was not estimated during the risk assessment. Mercury, as elemental or metallic mercury, is identified as a Class D carcinogen; in other words, it is not classifiable as a human carcinogen. This classification is based on the absence of adequate human and animal data that show a correlation between exposure to metallic mercury vapor and carcinogenicity. Mercury, as mercuric chloride, is identifiable as a Class C carcinogen. Class C indicates that mercuric chloride is a possible human carcinogen indicating inadequate data in humans and limited evidence of carcinogenicity in animals. No data are available on the carcinogenic effects of mercuric chloride in humans. Similar to mercuric chloride, methyl mercury is identified as a Class C carcinogen; a possible human carcinogen based on inadequate data in humans and limited evidence of carcinogenicity in animals. Three human studies were identified in the IRIS that examined the relationship between methyl mercury exposure and cancer. No persuasive evidence of increased carcinogenicity attributable to methyl mercury exposure was observed in any of the studies. Absorbed Doses Reference doses and slope factors are calculated based on toxicity testing that involves ingestion of the constituent being evaluated. It has been recognized that many constituents are not 100 percent absorbed through the gastrointestinal system. To utilize oral toxicity values (e.g .. RfD0 ) in estimating hazards associated with dermal contact exposures, it is necessary to apply a dermal correction factor to RfD0 when they are applied to absorbed intake values. A dermal correction factor of 10 percent was utilized for inorganic mercury (based on divalent mercury: ATSDR, 1994). A dermal correction factor of 100 percent was utilized for mercuric chloride and methyl mercury (ATSDR, 1994). d. Human Health Exposure and Risk Calculations In the baseline risk characterization, the results of the toxicity and exposure assessments are summarized and integrated into quantitative and qualitative expressions of potential risk for carcinogenic compounds and into a HI for non-carcinogenic compounds. The baseline risk characterization presents reasonable maximum exposure (RME) and average/ce:-itriil tendency exposures to baseline site conditions in the absence of additional site controls or remediation. Non-carcinogenic Hazard The potential for non-carcinogenic effects is evaluated by comparing an exposure level over a specified time period (e.g., life-time) with a reference dose (RID) derived for a similar Former Chlorine Plant Area of th"e Weyerhaeuser t;:ompany Site Record of Decision Martin County, NC September, 2003 34 • • exposure period. An RID represents a level that an individual may be exposed to that is not expected to cause any deleterious effect. The ratio of exposure to toxicity is called a hazard quotient (HQ). An HQ<l indicates that a receptor's dose of a single contaminant is less than the RID, and that toxic non-carcinogenic effects from that chemical are unlikely. The Hazard Index (HI) is generated by adding the HQs for all chemicals of concern that affect the same target organ (e.g., liver) or that act through the same mechanism of action within a medium or across all · media to which a given individual may reasonably be exposed. An Hkl .indicates that, based on the sum of all HQs from different contamiants and exposure routes, toxic non carcinogenic effects•from all contaminants are unlikely. An H1 >I indicates that site-related exposures may present a risk to human health. The HQ is calculated as follows: Non-cancer HQ = CDI/RID · Where CDI = chronic daily intake RID = reference dose CDI and RID are expressed in the same units and represent the same exposure period (e.g., chronic, sub-chronic, or short-term).

Summary of Risk Characterization As indicated in Table H-Sa the range of total industrial worker I-Ils under current and hypothetical future land use conditions, representing both RME and central tendency/average exposure assumptions, was less than 1. The total I-Il for the industrial worker was based on a summation of pathway I-Ils for the incidental ingestion of surface soil, dermal contact with. surface soil, and the inhalation of airborne soil particulates. As indicated in Table H-Sb, the range of total construction worker I-Ils representing central tendency/average exposure assumptions was less than 1. The range of total construction worker I-Ils reflecting reasonable maximum exposures ranged from below 1 (I-Il ,norgaruc m=,ry = 0.0039) to greater than 1 (I-Il mmuri, chloride= 2.3). The total I-Il for the construction worker was based on a summation of pathway I-Ils for the incidental ingestion of surface and subsurface soil, _dermal contact with surface soil, inhalation of airborne soil particulates, and incidental dermal contact with groundwater. r The results of the baseline risk evaluation for the Former Chlorine Plant Area indicate that exposure to affected media in the area does not present unacceptable hazard to industrial workers, if site use and conditions remain as they currently are. Industrial workers are not exposed to the high levels of mercury present in the subsurface soils, so only the surface soil sample results were used in the risk evaluation. The results of the risk evaluations of potential construction activities in the area indicate that reasonable maximum exposures could result in a potential hazard for this receptor in the absence of additional site controls or modified work practices. f. Uncertainty Analysis The primary goal of the uncertainty analysis is to provide a discussion of the key assumptions made in the risk assessment that may significantly influence the estimate of potential risk. A discussion of the sources of uncertainty contributing to the potential risk and the associated effects (overestimation or underestimation of risk) of these factors is presented in this section. In the absence of empirical-or site-specific data, assumptions are developed based on best estimates of exposure or dose-response relationships. To assist in the development of these estimates, EPA (1989, 1991) recommends the use of guidelines and standard factors in risk assessments conducted under CERCLA. The use.of these standard factors is intended to promote consistency among risk assessments where assumptions must be made. · Although the use of . standard factors undoubtedly promotes comparability, their usefulness in accurately predicting potential risk is directly related to their applicability to the actual site-specific conditions. Table H-6 summarizes the assumptions of the risk assessment that affect the estimates of exposure and potential risk.

The Baseline Ecological Risk Assessment (BERA) Due to the heavily industrialized setting of the Former Chlorine Plant Area, and given that the area is -predominantly paved, on-site exposure to ecological receptors in the Former Chlorine Plant Area is minimal. As aresult, an ecological risk evaluation was not performed for the on-site portion of the Former Chlorine Plant Area. However, potential ecological receptors associated with the Roanoke River that may be exposed to mercury in sediment or in the surface water were evaluated by EPA during the RI activities on the Roanoke River, using data obtained during the Former Chlorine Plant RI as well as data obtained during the Roanoke River RI.. The following sections discuss the findings of the BERA relating to mercury contamination in the river near the Former Chlorine Plant. , " a. · Measurement Endpoints There were a total of 9 assessment endpoints used to evaluate ecological risks in the Roanoke River BERA. The endpoints which are appropriate for the evaluation of mercury and methyl mercury in sediments and surface water are: • Protection of Benthic Macroinvertebrates • Protection of Insectivorous Birds • Protection of Fish • Protection of Omnivorous Birds • Protection of Camivorous/Piscivorous Birds • Protection of Omnivorous Mammals b. Effects Characterization The approach taken to conduct the R0anoke River BERA was based on multiple lines of evidence to evaluate ecological risks (i.e., multiple measurement endpoints for each assessment endpoint, and data from mulitple sources such as site-specific toxicity data, bioaccumulation tests, general literature and food chain modeling). The effects shcaracterization for each endpoint was based on the measurement endpoints specified below: • Protection of Benthic Macroinvertebrates: Risks to benthic macroinvertebrates were evaluated by comparison of river sediment concentrations to a range.of benchmark values that represent a low-and mid-point of effects concentrations to Former Chlorine Plant Are:i of the Weyerhaeuser Company Site Record of Decision Martin County, NC September, 2003 40 • • aquatic organisms. These effects ranges were published by Long, et al. (1995) and are termed ER-Land ER-M respectively. The ER-Lis the lower 10th percentile of the effects data, and the ER-Mis the median, or 50th percentile of the effects data. Risks were also evaluated by a toxicity test using Hyalel/a azteca. • Protection of Insectivorous Birds: Three types of data were collected for evaluation of exposure to this endpoint; chemical analysis of river sediments, chemical analysis of surface water, and a benthic macroinvertebraie bioaccumulation assay. The data were used in a food-chain model to evaluate risks to insectivorous birds following exposure to contaminated sediments, water and emergent insects. The barn swallow was selected as the representative insectivorous bird species. • Protection of Fish: Three types of data were collected for evaluation of exposure to this endpoint: chemical analysis of river sediments, fish tissue, and surface water. Risks were evaluated by comparison of measured fish tissue concentrations to risk- based fish tissue concentrations published by Jarvinen and Ankley (1999), and concentrations published in the Environmental Residue-Effects Database (ERED) published by the US Army Corp of Engineers Waterways Experiments Station. Measured surface water concentrations were compared to the State of North Carolina Water Qulaity Standards, and No-Observed Effects Concentrations (NOECs) and Lowest-Observed Effects Concentrations (LOECs) obtained from Jarvin and Ankley (1999). The redear sunfish, bluegill, and largemouth bass were selected as representative species, representing at least two different trophic levels. • Protection of Omnivorous Birds: Six types of data were collected for evaluation of exposure to this endpoint: chemical analysis of river sediments, fish, bivalves, and frogs, as well as a benthic macroinvertebrate bioaccumulation bioassay that provided tissue concentrations for L. variegatus (a surrogate for aquatic macroinvertebrates). The results of exposures to contaminants in these media were evaluated in a food-chain model. The wood duck was selected as the representative omnivorous bird species .. • Protection of Carnivorous/Piscivorous Birds: Exposure to this endpoint was evaluated using five types of data: chemical analysis of ri·ver sediments, surface water, fish, aquatic macroinvertebrates (from the L. variegatus bioaccumulation bioassay), and frcigs. The results of exposures to contaminants in these media were evaluated in a food-chain model. The osprey and the green heron were selected as respresentative species for this assessment endpoint. The osprey captures fish from the surface of the water while in flight and is exposed to chemicals in the fish tissue, with a small contribution from drinking contaminated surface water. The green heron stalks its prey from shallow water and may be exposed to chemicals in prey as · · Former Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision Manin County, NC .

The results of exposures to contaminants in these media were evaluated in a food-chain model. The racoon and the river otter were selected as representative omnivorous mammal species. c. Summary of Ecological Risk t ~ . Hazard Quotients and Remedial Goal Options were calculated for each assessment endpoint. Both the No-Observed Adverse Effects Level (NOAEL) and the Lowest-Observed Adverse Effects Level (LOAEL) are presented as a range of media concentrations that would result in rio adverse effects to those that would result in low adverse effects. The shallow sediments (0-6") are the only sediments considered available to ecological receptors. The shallow sediments collected in the Roanoke River in front of the Former Chlorine Plant have mercury concentrations ranging from 0.1 mg/kg to 0.77 mg/kg. The LOAL-based Remedial Goal Option for sediments at two locations for heron and river otter are slightly exceeded.

Mercury in the groundwater will be subject to reduction in concentration by natural physical and biochemical processes, although not significantly.· Alternative 2-Cooling Tower Repair with Groundwater Compliance and Trend Monitoring • Cooling Tower Repair, routine inspection • Surface Cover Improvements • River Bulkhead inspections/routine maintenance • · Groundwater compliance and trend monitoring • Land Use Restrictions • Capital Costs: Annual O&M Costs: Total PW Costs: $ 427,000.00 $ 143,163.00 $2,420,000.00 Duration to Finish Construction: 10-12 months Soils: The subsurface soils in the Former Chlorine Plant Area will remain in their present condition. Currently, all of the Former Chlorine Plant Area is covered with pavement or structures. However, there are small grassy areas around the edges of the area near the existing bulkhead where soil is present at the ground surface. This alternative includes covering these areas and maintaining the integrity of the existing cover, minimizing surface run-off to the Roanoke River. Groundwater: This alternative reduces the mass flux of mercury in the groundwater through the repair of the leaks from the cooling towers. The NCDENR is requiring the repair.of the cooling towers and end the discharge of cooling water to groundwater, regardless of any Former Chlorine Plant Area of the Weyerhaeuser Company Site Record of Deci~ion Martin County, NC September, 2003 45 ----·-------·----------------• • decisions associated with this ROD. This repair reduces the volume of water moving through the mercury containing soils below the Former Chlorine Plant and the modification of the flow path of the groundwater. · A groundwater monitoring network of approximately 31 wells will be installed and monitored in accordance with the North Carolina administrative process for establishing compliance monitoring locations under the NCAC 2L rules. The monitoring network will provide data needed to update the modeled hydrogeologic conditions under the Former Chlorine Plant Area. The mercury concentrations in the source area of the aquifer will me monitored, but it is estimated that groundwater concentrations will remain above the NCMAC of I. I µg/L in some locations within the building footprint for an excess of I million years. . 1~ Also included in this alternative are regular bulkhead inspections to evaluate and monitor the integrity of the existing bulkhead along the Roanoke River. These non-destructive, visual inspections would be conducted both above and below the water line, to the sediment surface. Routine maintenance of the bulkhead is included in this alternative. Land use restrictions: The land use restrictions would preclude the potable use of groundwater from the shallow aquifer beneath the Former Chlorine Plant and mercury plume areas. Currently, a map is on file with the Martin County Register of Deeds that identifies the Former Chlorine Plant Area as an Inactive Hazardous Substance or Waste Disposal Site (NCD 99 i-278-540): To the extent necessary, this deed notice will be revised as a part of the remedial design to reflect the selected remedy, to meet the current North Carolina administrative process, and any additional requirements to maintain the integrity of the remedy and to limit exposure to soil and groundwater. The Land use restrictions will be defined during the Remedial Design, and the State will continue to enforce the required controls. Alternative 3-Extended Flow Path and Groundwater Compliance and Trend Monitoring • • Flow path modification through bulkhead wall improvements Cooling tower repair • Surface cover improvements • • Groundwate, compliance and trend monitoring Land use restrictions • Capital Costs: Annual O&M Costs: Total PW Costs: $3,821,000.00 $ 65,163.00 $ 4,630,000.00 The soil and land use restriction components are the same as those described in Alternative 2. · Former Chio'rine Plant Ar~a of the Weyerhaeuser Company Site Record of Decision Manin County, NC September, 2003 46 • Groundwater: In addition to the cooling tower repair and groundwater compliance and trend monitoring components described in Alternative 2, this alternative includes the installation of a vertical barrier wall system along the Roanoke River, downgradient of the source area. This barrier system would reduce the mass flux of mercury in groundwater leaving the Former Chlorine Plant Area and discharging to the Roanoke River. The wall would be placed to a depth of approximately 45 feet below ground surface and would tie into the low permeability clay aquitard. The length of this wall is expected to cover approximately 520 feet of river frontage,. approximately 2.5 times longer than the length of the Former Chlorine Plant footprint (Figure J- 1). The barrier would consist of sealed sheet piling which will retard groundwater flow directly to the Roanoke River, with a design hydraulic conductivity of approximately 5.0 X 10·3 emfs, compared to the estimated hydraulic conductivity of the existing sheet pile bulkhead of approximately 1 X 10·5 emfs or more. The new bulkhead would be connected to the exi,s!ing bulkhead through a series of tie backs. The installation of this barrier wall would lengthen the flow path from the source area to the river as the groundwater would have to flow around the barrier rather than directly to the river though the existing unsealed wall. The flow path lengthening will increase the mass of soil (and therefore increase potential adsorptive surface area) that the groundwater will pass through, which will result in a greater amount of mercury mass adsorbed over time. However, because of the continuing source of mercury, the finite adsorptive capacity of the soil will in time be exceeded and the mercury flux to the river will ultimately return to the mass levels estimated for Alternative 2. As a result of the lengthened flow path a greater volume of aquifer will contain groundwater in excess of the NCAC 2L standard.

Various types of barrier walls can be utilized for the containment of mercury contaminated soils in the Former Chlorine Plant building footprint. For purposes of cost estimating in the FS, a se.aled sheet pile barrier wall was evaluated. The final material will be determined during remedial design but shall meet the specifications that follow. The wall enclosing the source area will consist of a sealed/low permeability barrier, with an estimated permeability of 5.0 X 10·8 emfs. The wall will be installed to approximately 45 feet below ground surface, tying into the low-permeability clay aquitard beneath the site. The conceptual wall has a total length of 610 feet, and would enclose an area of approximately 23,000 square feet and a volume of approximately 38,000 cubic yards of soil (Figure J-2). Approximately 7,200 pounds of mercury (or 96 percent of the estimated total mass of mercury) will be enclosed by the barrier. · Also included in this alternative as shown on Figure J-2 are two "target area" excavations. These target areas include excavation of both saturated and unsaturated soil. The excavations will extend to the practicable horizon and vertical limits near the former hypochlorite tank/central U-drain (Area I) and along the Eastern U-drain (Area 2). The excavations will removed surface soil and subsurface soil to a mercury level of 20 mg/kg. Structural sheet piling will be utilized for excavation stabilization and shoring. It is assumed that interlocking sheet piling will be driven to 25 feet around Area I and 20 feet around Area 2. No de-watering of soil is anticipated. Solidification of excavated, saturated soil will be performed in constructed bunkers with the addition of a solidification agent such as fly ash. Area I has a surface area of approximately 2,000 square feet. At an average depth of IO feet, excavation would remove approximately 750 cubic yards of soil. About 80 pounds of mercury would be removed from Area I (approximately I percent of the estimated total mass of mercury). Area 2 measures approximately 10 feet by 55 feet, and at an average depth of 8 feet, a total of 150 cubic yards ofsoil would be excavated, containing approximately 230 pounds of mercury (about 3 Fo~er Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision Martin County. NC September. 2003 · 49 • • percent of the total mass of mercury). The Toxicity Characteristic Leaching Procedure (TCLP) limit for mercury (40 CFR 261.24) is 0.2 mg/L. The TCLP values for the shallow soil samples from the Former Chlorine Plant have historically not exceeded 0.09 mg/L, even in soil with total mercury concentrations as high as 2,900 mg/kg. IfTCLP results are above 0.2 mg/L·and total mercury concentrations are greater than or equal to 260 mg/kg (40 CFR 268.40), then the material must be retorted (or equivalent process) to recover and recycle the mercury as per the Universal Treatment Standard (UTS). For purposes of cost estimating it was assumed that materials from Area 1 wo,uld be nonhazardous as defined by the TCLP. In Area 2, it was assumed that 50 percent of the · excavated material would be nonhazardous and 50 percent would be hazardous. The nonhazardous materials would be disposed of at the facilities nonhazardous landfill, or offssite at a nonhazardous landfill, and the hazardous material will be sent to an off-site retort facrtfiy for treatment prior to disposal. The excavations will be backfilled with clean fill material and covered. The surface cap containment system will require the replacement of pavement over · areas disturbed. by the barrier wall installation, the excavations, and the currently un-covered . surface soil adjacent to the river. Groundwater: Mercury concentrations in groundwater immediately outside of the containment area are assumed to be 2.3 µ.g/L. Concentrations of mercury in the groundwater outside of the containment area are estimated to fall below the NCMAC of 1.1 µ.g/L in 4 years. However, these flushing calculations did not take into account t!Je sorption of mercury to soil. If· mercury sorption to soils is included, with a low retardation factor of 10 for example, it would require 40 years to reach the NCMAC. To assess the mercury concentration trends in groundwater, this alternative includes the implementation of a groundwater compliance and trend monitoring program consisting of 12 monitoring wells sampled over 30 years in accordance with the North Carolina administrative process for establishing compliance monitoring locations under the NCAC 2L rules.

The surface cover replacement is also the same. The land use restrictions are the same as those described in Alternative 2. Groundwater: This alternative funnels impacted groundwater through an in-situ treatment gate between the impacted saturated soil beneath the Former Chlorine Plant footprint and the Roanoke River. A low permeability vertical barrier would be used to construct the in- situ funnel and activated carbon will form the reactive media in the center of the funnel. This reactive media in the treatment gate would remove aqueous mercury from groundwater that passes beneath the Former Chlorine Plant. A treatability study was performed for this site. The results have been used to estimate the effectiveness of the overall alternative. The funnel and gate system has been conceptually sized and oriented to direct approximately 97 percent of the groundwater that enters the funnel system through the treatment gate. The treatment gate media would be installed from near surface to approximately 40 feet below the ground surface, where the low-permeability clay aquitard is encountered. The engineered funnel would consist of joint- sealed steel sheet piling installed to approximately 45 feet. Figure J-3 shows the details of the wall alignment and Figure J-4 shows the conceptual treatment gate. The ground surface length of joint-sealed sheet piling associated with the funnel totals 340 feet. The hydraulic conductivity will be 5.0 x10-s emfs. The hydraulic conductivity of the aquifer is approximately 6.0 X 104 emfs (upper), 2 0 X 10·3 emfs (middle) and 6.0 X 10·3 emfs· (lower); and the hydraulic conductivity of the mixed reactive media is expected to be no less than 6.0 x10·3_ Given the differences in hydraulic conductivity, it is expected that the sealed sheet piling on either side of the reactive media will serve as a funnel that directs groundwater flow through the reactive gate. The 90-foot-long treatment zone within the gate would be 6 feet wide and 36 feet high, and would consist of a 50/50 mixture by volume of granular activated carbon and sand. The 50/50 mixture was chosen to enhance flow and constructability. Numerical simulations determined flow through the gate to be 98 cubic feet per day (0.8 gpm). The calculated average effluent on the other side of the gate is 0.0000129 µg/L after 30 years of Fom1er C:hlorine Plant Area of the Weyerhaeuser_ Company Site Record of Decision Martin County.

Area 1 is not included because it is contained within the hydraulic containment area described below. The cover replacement and land use restrictions are the same as previously described. Groundwater Extraction: Mercury contaminated groundwater would be removed from the shallow aquifer below the Former Chlorine Plant Area through three groundwater extraction wells and conveyed to a treatment system by means of underground forcemains. The conceptual design of the extraction and conveyance network are shown on Figure J-5. The wells will extend to the top of the low-permeability clay unit (approximately 40 feet bgs) and will have a screened interval of 35 feet. The extraction wells are expected to have a combined flow rate between 7.5 and 15 gpm. The resulting capture zone is shown in Figure J-5. The estimated composite influent mercury concentrations entering the treatment system are expected to be between 0.30 and 0.76 µg/L. Given the mass of mercury present below the Former Chlorine Plant Area, the pumping will have to continue for 100,000's of years before the NCMAC is achieved. Groundwater Treatment: Flocculation/Precipitation pretreatment: Because of the specific groundwater chemistry, it is anticipated that the extracted groundwater stream will require pretreatment. The conceptual design consists of reactor and clarifier modules. Air or chemicals would be injected into the groundwater in the reactor module to drive ferrous iron into the ferric state, initiating precipitation to remove the high levels of iron in the groundwater. Then, a flocculent polymer would be injected as the water is transferred to the clarifier module. The clarifier module is used to remove and collect the precipitated solids. Potentially, a significant amount of mercury could be incorporated into the iron matrix and removed during the flocculation/precipitation process. As a conceptual design estimate, a 50 percent mercury removal is assumed during the pretreatment process: Sludge generated during the solids removal process would be pressed and Former Chlorine Plant Area of the Weyerhaeuser Company Site Record of DeCision Manin County, NC September, 2003 56 • • disposed of in the facility's on site nonhazardous waste landfill. Approximately 5 cubic feet of sludge cake would be generated per day. Liquid-phase carbon adsorption treatment train: Following the pretreatment step, carbon adsorption would be used to treat the effluent from the clarifier module. It is assumed that the removal efficiency of the Granular Activated Carbon (GAC) would be 50 percent. Based on the treatability study it is estimated that between 3,000 and 6,000 pounds per year of carbon will be needed. The treatment system would consist of two parallel trains of two 1 ,000-pound carbon units to allow for continuous operation. It was assumed for cost estimating purposes that the spent carbon would be nonhazardous following testing, and would disposed of in the facility's on-site landfill. ,. Ion exchange resin: After exiting the carbon treatment train, the w.ater stream would be passed through treatment vessels containing ion exchange resin, and, if require, through a post- filtration process to remove any additionally-precipitated solids or resin. A 75 percent mercury removal efficiency is assumed for this part of the treatment system. Vessel replacement may be necessary as often as once per year. Pending waste concentration and characteristic testing, the spent resin would either be disposed of as a hazardous waste, treated at a retort facility and . disposed as a hazardous waste, or as a nonhazardous solid waste in the facility's on-site landfill. Discharge compliance: Based on the information presented and the treatability study work performed, the mercury concentrations in the effluent stream are expected to be <0.1 µg/L ,0,...... but likely higher than 0.012 µ.g/L, the current North Carolina surface water quality standard for \;:'' mercury. Groundwater compliance and trend monitoring will also be performed under this alternative in accordance with the North Carolina administrative process for establishing compliance monitoring locations under the NCAC 2L rules. It is estimated that 13 of the existing monitoring wells will be sampled along with 4 new wells. In addition, each extraction well's concentration and flow, treatment system influent, intermediate (between carbon or ion exchange vessels) and treatment system effluent will be sampled monthly. former Chlorine Plant Area of the Weyerh,wuser Company Site Record of Decision Martin County.

Soil: This alternative primarily consists of source area excavation and off-site disposal of excavated mercury-bearing soil. Figure J-6 presents the conceptual plan of the excavation alternative. The excavation would have to be performed in phases to allow manufacturing operations to continue and to allow various target depths to be structurally supported with sheet- piling engineering controls. A total of 10 excavation phases ranging from 10 to 40 feet below ground surface in depth are presented on Figure J-6. A majority of the excavations are expected to be performed in the wet, but dewatering is assumed for some deeper excavation phases. The collected groundwater from the dewatering, as well as decant water from saturated soil would require treatment prior to any discharge. The excavation area is approximately 24,000 square feet, and the total volume of soil to be excavated is approximately 16,000 cubic yards. For cost estimating purposes, it was estimated that approximately 1,050 cubic yards of soil having mercury concentration of 260 mg/kg or above would be treated as a hazardous waste and require off-site management at a retort facility. The remainder of the nonhazardous soil would be placed in the facility's on-site landfill, permitted by NCDENR. As with Alternative 3, the soil will be amended with fly ash when necessary for solidification. Upon cell completion and confirmation sampling at each excavation, the cell would be backfilled with clean fill, the fill would be compacted in multiple lifts, and the excavation are would ultimately be paved to match the existing facility ground surface. Groundwater: This alternative involves leaving in-place mercury contaminated groundwater above theNCMAC of 1.1 µg/L in the areas beyond the limits ofthe excavation. It is estimated that between 2 and 20 years will be required for natural processes to reduce mercury levels in groundwater to below the standard. A total of 12 wells would be used to monitor groundwater for compliance and contaminant reduction in accordance with the North Carolina administrative process for establishing compliance monitoring locations under the NCAC 2L rules.

Common Elements, Distinguishing Features and Expected Outcomes With the exception of the no action alternative, the components of each alternative are designed to be protective of human health and the environment. As such, all of the active alternatives incorporate components to maintain land use controls needed to control direst contact exposure pathways and will provide long-term protection of human health. For all alternatives, except Alternative 7, mass excavation, the mass of mercury will remain in place. To limit future impacts and improve the long term reliability of those alternatives where mercury is· left on site, various containment approaches and/or inspections are incorporated into the remedial alternatives. · The environmental impacts associated with continued migration of mercury to the ,- groundwater with ultimate discharge to the Roanoke River will be controlled to differing levels in each alternative. Each alternative has some uncertainty regarding long-term adequacy, reliability and permanence. Therefore, all of the alternatives, except no-action, will include groundwater monitoring to assess the long-term effectiveness of mass removal, mass containment, reduction through natural processes and/or groundwater treatment, in accordance with the North Carolina administrative process for establishing compliance monitoring locations under the NCAC 2L rules. None of the alternatives directly reduce the toxicity of mercury. However, by removing mercury-bearing soil and by removing mercury form groundwater, the potential toxicity of the media are reduced. There are significant differences l,etween the altemati ves with regard to· mercury mobility as measured by mass flux reduction to the Roanoke River. A general qualitative comparative summary for each alternative for the broad criteria of compliance with ARARs, effectiveness, implementability and cost is presented in Table J~l.

However, the 2L standard provides admioisll1ltivc prOvisions to identify points of compliance or cslllblish alternate provisions to accommodate natural attenuation. - Surface water discharge compliance consists of meeting the to-be-established discharge requircmeou for treated waters to the Roanoke Ri..,er. Although the current surface water quality staodard for mercury (0.012 µg/L) is not a set discharge criterion, the alternati..,e contains a surface water discharge component for which the mercury cooccntntion will likely exceed 0.01-2 µg/L · The estimated mass flux or mercury is rrom the R:P area to the Roanoke River. The percent reduction of the aqueous mercury mass flux is compared lo the No Action Alternative (5.4 g/ycar).

Summary of Comparative Analysis of Alternatives In this section, each alternative is assessed using nine evaluation criteria required under the NCP (NCP§300.430 (l)(S)(i)). The seven threshold and balancing criteria serve as the basis for conducting the detailed and comparative analysis of the Alternatives presented in the previous section. Companson of the alternatives with respect to these evaluation criteria are presented in summary form This approach is designed to provide sufficient information to adequately compare the alternatives, aid in the selection of an appropriate remedy for the Site, and demonstrate satisfaction of the statutory requirements. The evaluation criteria are briefly descri.bed below. Table K-1 presents the comparison of the alternatives with respect to the evaluation criteria (without State and Community," · acceptance), and in relation to one another. Threshold Criteria 1. Overall Protection of Human Health and the Environment Overall protection of human health and the environment addresses whether each alternative provides adequate protection of human health and the environment and describes how risks posed through each exposure pathway are eliminated, reduced, or controlled, through treatment, engineering controls, and/or institutional controls. 2. Compliance with Applicable or Relevant and Appropriate Requirements (ARARS) Section 12l(d) of CERCLA and NCP §300.430(1)(l)(ii)(B) require that remedial actions at CERCLA sites at least attain legally applicable or relevant and appropriate Federal and State requirements, standards, criteria, and limitations, which are collectively referred to as "ARARs", unless such ARARs are waived under CERCLA section 12l(d)(4). Applicable requirements are those cleanup standards, standards of control, and other substantive requirements, criteria, or limitations promulgated under Federal environmental of State environmental or facility siting laws that specifically ·address a hazardous substance, pollutant, contaminant, remedial action, location, or other circumstance found at a CERCLA site. Only those State standards that are identified by a state in a timely manner and that. are more stringent than Federal requirements may be applicable. Relevant and appropriate requirements are those cleanup standards, standards of control, and other substantive requirements, criteria, or limitations promulgated under Federal environmental or State environmental or facility siting laws that, while not "applicable" to a hazardous substance, pollutant, contaminant, remedial action, location, or other circumstance at a CERCLA site, address problems or situations sufficiently similar to those encountered at the CERCLA site that their use is well-suited to the ·Fonner Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision Martin County, NC September, 2003 63 .. ·.:..: • • particular site. Only those State standards that are identified in a timely manner and are more stringent than Federal requirements may be relevant and appropriate. To-Be-Considered Requirements (TBCs) are Federal and State environmental and public health agency criteria, advisories, guidance, and proposed standards that are not legally enforceable but contain information that is useful in carrying out, or in determining the level of protectiveness of, selected remedies: TBCs are meant to compliment the use of ARARs, not to compete with or replace them. Because TBCs are not ARARS, their identification and use are not mandatory. Where no_ARARs address a particular situation at a CERCLA site, or the existing ARARs do not ensure sufficient protectiveness, the TBC advisory, criteria or guidelines should be used to evaluate alternative remedial actions. Compliance with ARARs addresses whether a remedy will meet all of the applic.;i.ble or ' relevant and appropriate requirements of Federal and State environmental statutes, or provides a basis for invoking a waiver. Balancing Criteria 3. Long-Term Effectiveness and Permanence Long-term effectiveness and permanence refers to expected residual risk and the ability of a remedy to maintain reliable protection of human health and the environment over time, once clean-up levels have been met. This criterion includes the consideration of residual risk thatwill /;~\( remain on-site following remediation and the adequacy and reliability of controls. 4. Reduction of Toxicity, Mobility, or Volume Through Treatment Reduction of toxicity, mobility, or volume through treatment refers to the anticipated performance of the treatment technologies that may be included as part of a remedy, and examines the extent to which ·the remedial alternative achieves the statutory preference for corrective action that permanently and significantly reduces the toxicity, mobility, and volume of contaminants. 5. Short-Term Effectiveness Short-term effectiveness addresses the period of time needed to implement the remedy and any adverse impacts that may be posed to workers, the community, and the environment during construction and operatio_n of the remedy until clean-up levels are achieved. 6. Implementability Implementability addresses the technical and administrative feasibility of a remedy from design through construction and operation. Factors such as availability of services and materials, former Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision · Martin County. NC _ September, 2003 64 ;..--' • • administrative feasibility, and coordination with other governmental entities are also considered. 7. Cost The estimated present worth costs for the alternatives range from$ 215,785 for Five year reviews under Alternative 1 to$ 17,619,000 for Alternative 7. Modifying Criteria 8. State Acceptance The State of North Carolina supports Alternatives 4 through 7. 9. Community Acceptance During the public comment period, the community supported the need for remedial action, and there was support for Alternative 4 and Alternative 7. ·Fonner Chlorine Plant Area of the Weyerhaeus_er Company.Site Record of Decision Martin County.

Principal Threat Wastes The NCP establishes an expectation that EPA use treatment to address the principal threats posed by a site wherever practical (NCP §300.430(a)(l)(iii)(A)). Identifying principal threat waste combines concepts of both hazard and risk. In general, principal threat waste are those source materials considered to be highly toxic or highly mobile; which generally cannot be contained in a reliable manner or would present a significant risk to human health or the environment should exposure occur. The mercury contaminated soils are considered to be "principal threat wastes". Mercury is a highly toxic substance, and is present in high quantities at the site. There is a significant possibility that, absent remedial action, a release of the large quantities of mercury present in on-site subsurface soils may occur, resulting in an unacceptable risk. The alJ,c:Inatives which address the containment or excavation of the mercury contaminated soils address this risk. Alternatives I, No-action, would not address the principal threats at the site. Alternatives 2, 3, and 6 are groundwater alternatives and do not address the contaminated soil. Alternative 5 provides for partial containment of contaminated soils, and some excavation, but is still primarily a groundwater alternative. Alternative 4 provides for effective containment of the majority of the soil contaminated with mercury, and some limited excavation, treatment and disposal. Alternative 7 would significantly reduce the risk by excavation, treatment and off-site disposal. former Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision · Martin County. NC September. 2003 70 M. The Selected Remedy The Selected Remedy for the Former Chlorine Plant Area is Alternative 4-Containment with Groundwater Compliance Monitoring and Trend Monitoring. 1. Summary of the Rationale for the Selected Remedy Alternative 4 provides the best balance of the nine evaluation criteria of all of the Alternative remedies reviewed for the site. In terms of the balancing criteria, Alternative 4 provides for protection of human health and the environment through the installation of a barrier system around the mercury contaminated soils, excavation of soils adjacent to the river, groundwater compliance monitoring, and land and groundwater use restrictions. The barrier system will prevent a catastrophic release of the nearly 7,500 pounds of mercury presen; in on- site soils to the adjacent Roanoke River. Alternative 4 would allow the groundwater outside of the barrier wall to remain above the chemical-specific ARAR for total mercury of 1.1 µg/L, however the groundwater is expected to naturally recover with time and will be monitored for compliance. In the interim, groundwater potable use restriction will prevent exposure to mercury in the shallow aquifer. Alternative 4 will be effective and reliable over the long term by containing impacted soil and residual groundwater within the containment barrier system. Alternatives I, 2, 3, 5 and 6 are primarily groundwater alternatives which do not address the principal threat of the mercury contaminated soil. Alternative 4 would effectively and permanently remove the source materials · in Areas I and 2. Only Alternative 7 provided for a permanent removal of all of the principal threat waste. Natural processes should be effective with time in reducing residual groundwater contamination outside of the barrier system. Alternative 5 and 6 are more active groundwater treatment remedies, but the groundwater restoration time frames are still in the hundreds of thousands of years. Surface pavement and the barrier system will reduce the mobility of the largest source of mercury in soils. Excavation in limited source Areas I and 2 will remove these source areas and reduce their impacts to groundwater. Mercury flux from the source area to the · river is expected to be reduced by 97 percent. All components of Alternative 4 are implementable in the short term, and should have minimal adverse effects on the community, employee health or the environment duririg implementation, although the work will be performed in a very active portion of the facility and will require extensive planning. Only Alternatives I and 2 are more easily implemented than Alternative 4. The remainder of the alternatives will be disruptive in the short term. Alternative 7 would present the highest degree of difficulty for implementation of 10 phased excavations, and would also present significant worker health and safety concerns. The equipment and personnel required to implement Alternative 4 are available, and workers would have safety training and wear appropriate personal protective equipment Former Chlorine Plant Area of the Weyerhaeuser Company Site Record of Decision · · Martin County.

Description of the Selected Remedy This alternative consists of the installation of a vertical barrier wall system around the source area, and "targeted" excavation of soil from the CentraJ.U-drain area ·and the Eastern U- drain area. Various types of barrier walls can be utilized for the containment of mercury contaminated soils in the Former Chlorine Plant building footprint. For purposes of cost estimating in the FS, a sealed sheet pile barrier wall was evaluated. The final material will be determined during remedial design but shall meet the specifications that follow. The wall enclosing the source area will consist of a sealed/low permeability barrier, with an estimated permeability of 5.0 X 10-s cm/s. The wall will be installed to approximately 45 fe~t below ground surface, tying into the low-permeability clay aquitard beneath the site. The conceptual wall has a total length of 610 feet, and would enclose an area of approximately 23,000 square feet and a volume-of approximately 38,000 cubic yards of soil. Approximately 7)00 pounds of mercury (or 96 percent of the estimated total mass of mercury) will be enclosed by the barrier. Also included in this alternative are two "target area" excavations. These target areas include excavation of both saturated and unsaturated soil. The excavations will extend to the practicable horizon and vertical limits near the former hypochlorite tank/central U-drain (Area l_) and along the Eastern U-drain (Area 2). The excavations will removed surface soil and subsurface soil to a mercury level of 20 mg/kg. Structural sheet piling will be utilized for excavation stabilization and shoring. It is assumed that interlocking sheet piling will be driven to 25 feet around Area 1 and 20 feet around Area 2. No de-watering of soil is anticipated. - Solidification of excavated, saturated soil will be performed in constructed bunkers with the addition of a solidification agent such as fly ash. Area I has a surface area of approximately 2,000 square feet. At an average depth of 10 feet, excavation would remove approximately 750 cubic yards of soil. About 80 pounds of mercury would be removed from Area 1 (approximately 1 percent of the estimated total mass of mercury). Area 2 measures approximately 10 feet by 55 feet, and at an average depth of 8 feet, a total of ISO cubic yards of soil would be excavated, containing approximately 230 pounds of mercury (about 3 percent of the total mass of mercury). The Toxicity Characteristic Leaching Procedure (TCLP) limit for mercury ( 40 CFR 261.24) is 0.2 mg/L. The TCLP values for the shallow soil samples from the Former Chlorine Plant have historically not exceeded 0.09 mg/L, even in soil with total mercury concentrations as high as 2,900 mg/kg. If TCLP results are above 0.2 mg/Land total mercury concentrations are greater than or equal to 260 mg/kg (40 CFR 268.40), then the material must be retorted (or equivalent process) to recover and recycle the mercury as per the Universal Treatment Standard (UTS). For purposes of cost estimating it was assumed that materials from Area 1 would be nonhazardous as defined by the TCLP. In Area 2, it was assumed that SO percent of the excavated material would be nonhazardous and SO percent would be hazardous. The nonhazardous materials would be disposed of at the facilities nonhazardous landfill, or off-site at a nonhazardous landfill, and the hazardous material wiil be sent to an off-site retort facility for Former Chlorine Plant-,Arca of the Weyerhaeuser Company Site Record of Decision Martin County, NC September, 2003 72 • • treatment prior to disposal. The excavations will be backfilled with clean fill material and covered. The surface cap containment system will require the replacement of pavement over areas · disturbed by the barrier wall installation, the excavations, and the currently un-covered surface soil adjacent to the river. · To assess the mercury concentration trends in groundwater, this alternative includes the implementation of a groundwater compliance and trend monitoring program consisting of 12 monitoring wells sampled over 30 years . . The land use restrictions would preclude the potable use of groundwater from the shallow aquifer beneath the Former Chlorine Plant and mercury plume areas. CurrentlX,Jl'map is on file with the Martin County Register of Deeds that identifies the Former Chlorine Plant Area as an Inactive Hazardous Substance or Waste Disposal Site (NCD 991-278-540). To the e,i:tent necessary, .this deed notice will be revised as a part of the remedial design to reflect the selected remedy, to meet the current North Carolina administrative process, and any additional requirements to maintain the integrity of the remedy and to limit exposure to soil and groundwater. · The remedy described in this section may change somewhat as a result of-the remedial design and construction processes. Changes to the remedy described in this ROD will be documented using a technical memorandum in the Administrative Record, an Explanation of Significant Differences (ESD) or by a ROD Amendment, depending on the magnitude of the proposed change.· 3. Summary of the Estimated Remedy Cost The detailed cost estimate for Alternative 4 is shown on Table M-1. The cost estimate presents the capital, annual O&M, and total present worth costs projected over 30 years. The information in this cost estimate summary table is based on the best available information regarding the anticipated scope of the remedial alternative. Changes in the cost elements are likely to occur as a result of new information and data collected during the engineering design of the remedial alternative. Major changes may be documented in the form of a memorandum in the Administrative Record file, an ESD or a ROD amendment. This is an order-of-magnitude cost estimate that is expected to be within +50 to -30 percent of the actual projected cost.

Expected Outcomes of the Selected Remedy Former Chlorine Plant-Area Clean-up Levels • The cleanup levels selected for the contaminated media at the Former Chlorine Plant Area were developed using the results of the risk assessment and by comparison to ARARs. A risk-based cleanup level was derived for soil as well as a level that was protective of groundwater. The soil cleanup level was derived using partitioning coefficient calculations, which result in no exceedence of groundwater standards. This level was lower than the risk-based soil exposure level, and is therefore selected as the soil cleanup level. Table M-2 provides the cleanup levels for the Former Chlorine Plant Area.

Statutory Determination The purpose of this section is to provide a description of how Alternative 4 satisfies the statutory requirements of CERCLA §121 (as required by NCP §300.430 (f)(S)(ii)) and explain the Five-Year Review requirements for the Former Chlorine Plant Area. · I. Protection of Human Health and the Environment Alternative 4 is protective of human health and the environment by eliminating, reducing, or controlling risk posed by the Former Chlorine Plant Area through containment of contaminated soils, "targeted" excavation in the U-drains, groundwater monitoring and institutional controls. The containment of the contaminated soils is justified even though current concfiiions have not resulted in a release posing risk.· There is a significant possibility that, absent remedial action, a release of the large quantities of mercury present in on-site subsurface soils may occur, resulting in an unacceptable risk. The significance of this potential risk was evaluated based on the quantities of mercury (approximately 7,500 lbs) in soil as well as the environmental setting of the Former Chlorine Plant Area adjacent to the Roanoke River (EPA, 1991 ). In addition, where factors such as complex hydrogeology or contaminant characteristics constrain groundwater restoration, EPA's approach is to emphasize removal or treatment of source materials, containment of non-restorable source areas, and restoration of aqueous contaminant plumes (EPA, 1995). · The barrier wall containment system would effectively control the migration of mercury . from the source area into groundwater and from migrating to the Roanoke River. Under this Alternative, the mass flux of mercury from the Former Chlorine Plant Area to the Roanoke River would be decreased by 94 percent, compared to the no further action Alternative. The potential exposure pathway for groundwater would be eliminated by preventing installation of potable· water wells in the vicinity of the Former Chlorine Plant Area. By performing the "target" area excavations, treatment and disposal, Alternative 4 incorporates a treatment component as well a provides further protection of human health and the environment. The mass removal would reduce potential future direct contact hazards as well as decrease source area mercury mass that could impact groundwater and the Roanoke River. 2.

The overali effectiveness cif a remedial alternative is determined by evaluating three of the five balancing criteria }l.~ed in the detailed analysis of alternatives: (1) Long-term effectiveness; (2) Reduction of toxicity, mobility and volume; and (3) Short-term effectiveness. The overall effectiveness is then compared to the cost. In addition, the cost effectiveness of each alternative in relation to one another is also compared. Table K-1 summarized the cost-effectiveness comparison of the remedial alternatives for the Former Chlorine Plant Area. Through this comparison, EPA has determined that Alternative 4 is a cost-effective remedy for the Former Chlorine Plant Area. 4. Utilization of Permanent Solutions and Alternative Treatment Technologies to the Maximum Extent Practicable Alternative 4 is primarily a containment remedy. The excavation and off-site treatment of a limited quantity of the mercury contaminated soils in Areas I and 2 will provide permanent removal of only about 3% of the total mass of mercury in on-site soils. However, the containment barrier system will effectively contain the majority of the mass of mercury in place at the site, and will permanently reduce the mass flux of mercury to the groundwater and ultimately the Roanoke River by an estimated 97%. As demonstrated during the treatability study work conducted for the site, treatment of mercury in groundwater is difficult and even when the use of sequential systems the effluent can not be reliably reduced to below surface water discharge standards. The residual groundwater contamination outside of the containment system will be reduced by natural processes within a reasonable period of time, but will not be effective in limiting future exposure to human receptors without the use of institutional controls. The same would hold true for all of the alternatives evaluated because each had some residual groundwater contamination which requires long-term monitoring. 5. Preference for Treatment as a Principal Element Alternative 4 is primarily a containment alternative, but does include some limited excavation and treatment within the source Areas I and 2.

However, there is a significant possibility that, absent remedial action, a release of the large quantities of mercury present in on-site subsurlace soils may occur, resulting in an unacceptable risk. The NCP establishes an expectation that EPA use treatment to address the principal .threats posed by a site wherever practical (NCP §300.430(a)(l)(iii)(A)). The complex environmental setting and the limitations of in-situ treatment technologies for the mercury in soils and groundwater eliminated these treatment alternative. The majority of the so~rce materials at the Former Chlorine Plant Area can be reliably contained in the long term. 6. Five-Year Reviews -.. The NCP §300.430 (f)(4)(ii) requires a five-year review if the remedial action results in hazardous substances, pollutants, or contaminants remaining on-site above levels that allow for unlimited use and unrestricted exposure. This (these) reviews will be conducted every five-years, and will evaluate whether the remedy remains protective, or will be protective, of human health and the environment. Alternative 4 will result in hazardous substances, pollutants or contaminants remaining in place at the Former Chlorine Plant Area. Pursuant to CERCLA § 121(c) and NCP §300.430 (f)(S)(iii)(C), a statutory five-year review is required five years from the beginning of on-site construction at the Former Chlorine Plant Area site. 0. Documentation of Significant Changes The Proposed Plan for the Landfill No. I site was released for public comment on July 3, 2003. The Proposes Plan identified Alternative 4 as the preferred alternative for the site. EPA reviewed all written and verbal comments submitted during the public comment period.

Any outstanding construction items discovered during the inspection still requiring correction shall be identified and noted on a punch list. If any items are still unresolved, the inspection shall be considered to be a Prefinal Construction Inspection requiring another Prefinal Construction Inspection Report and subsequent Final Construction Inspection. E. Interim Remedial Action Report Within sixty (60) days following the (i) cqnclusion of the Final Construction Inspection or (ii) date upon which Settling Defendant receives notice that the Prefinal Construction Inspection Report is approved, and that a Final Construction Inspection will not be required, Settling Defendant shall submit an Interim Remedial Action (RA) Report. EPA will review the draft report and will provide comments to Settling Defendant. The Interim RA Report shall be generally.consistent with EPA guidance for preparing the report (Close Out Procedures for National Priorities List Sites, EPA, OSWER Directive 9320.2- 09A-P) and include the following: 1. Introduction, providing a brief history_ and description of the site 2. Operable Unit Background 3. Construction Activities 4. Chronology of Events, including a projection of when clean-up levels for the groundwater will be achieved 5. Performance Standards and Construction Quality Control 6. Final Inspection and Certifications 7. Operation and Maintenance Activities 12 • • After EPA review, Settling Defendant shall address any comments and submit a revised report. The Remedial Action shall be complete when EPA approves the Interim RA Report. However, the long term remedial action will not be considered complete until all cleanup goals have been achieved. Further details can be found in the following Section F. F. Final Remedial Action Report Within thirty days (30) days following the receipt of sampling data documenting the achievement of all cleanup goals specified in the ROD, the Settling Defendant shall submit a Final Remedial Action (RA) Report. EPA will review the draft report and will provide comments to Settling Defendant. The Final RA Report shall be consistent with EPA guidance for preparing the report (Close Out Procedures for National Priorities List Sites, EPA, OSWER Directive 9320.2- 09A-P). When an interim RA report has already been prepared, the interim RA report can be simply amended to create the final RA report. The amendment would add information on activities that occurred after the interim RA report was completed. TASK IV -PERFORMANCE STANDARDS VERIFICATION AND OPERATION AND MAINTENANCE Settling Defendant shall submit a Performance Standard Verification and Operation and Maintenance Plan (PSV/OM Plan) 30 days after EPA approval of the RA workplan.

North Carolina Department of Environment and Natural Resources Water Quality Division, Groundwater Section 943 Washington Square Mall Washington, NC 27889 Subject: Variance Request for Abandonment of Wells Dear Mr. Hardison: Corporate Headquarters PO Box 9777 Federal Way WA 98063-9777 Tel {153) 9141345 IDJil @Tfi~ rn\~1 l\f\1 AUG .,,_. S 2004 \~ SUPERFUND SECllON Weyerhaeuser Company is requesting a variance to 15A NCAC 02C .0113(b)(1)(C) to allow two groundwater monitoring wells to be abandoned without disinfecting the wells prior to abandonment. TI1e two wells scheduled for abandonment are groundwater monitoring wells, CP-08-1 and CP-08-2, for Weyerhaeuser's Former Chlorine Plant site in Martin County, Plymouth, North Carolina (see attached figure). As previously approved by EPA, these wells are to be abandoned and replaced since they are currently located in an area where surface water occasionally accumulates after rainfall events. Replacement wells will be located approximately 15 feet west of their current locations. Total well depths and screened intervals of the replacement wells will be consistent with the existing wells. Well abandonment and replacement will be conducted by Parratt-Wolff, Inc who will be under contract with RMT, Inc., the EPA-approved Supervising Contractor for the Former Chlorine Plant. This variance is requested since the introduction of hypochlorite into the abandoned wells will change the redox condition of the groundwater, resulting in the unpredictable altering of dissolved mercury concentrations that will be measured in the adjacent replacement wells. As such, we are concerned that the generation of useful information on the fate of mercury at the site will be questionable. For this reason, we are requesting a variance for the requirement for a disinfectant. Given the local stratigraphy underlying the Former Chlorine Plant, we do not believe that abandonment of these wells without chlorination will compromise potable water at the Plymouth mill or vicinity. (Regional geology and hydrogeology for the Plymouth area is further described in the EPA's Record of Decision for the Former Chlorine Plant, September 2003, and in the Former Chlorine Plant Feasibility Study, RMT, Inc., June 2003.) Weyerhaeuser would very much appreciate your verbal approval for our request before Wednesday, August 4, when the wells are scheduled to be abandoned. I can be reached at 253-924-6650. Please call rne or Kris Krause, RMT, Inc. (608-662-5178) if you have any questions.

BACKGROUND A. The United States of America ("United States"), on behalf of the Administrator of the United States Environmental Protection Agency ("EPA"), filed a complaint in this matter pursuant to Sections l06 and l07 of the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), 42 U.S.C. §§ 9606, 9607. B. The United States in its complaint seeks, inter alia: (I) reimbursement of costs incurred by EPA and the Department of Justice for response actions at the Weyerhaeuser Company Plymouth Wood Treating Plant site in Martin County, North Carolina, together with accrued interest; and (2) performance of studies and response work by the defendant at OU! consistent with the National Contingency Plan, 40 C.F.R. Part 300 (as amended) ("NCP"). C. In accordance with the NCP and Section 12l(f)(l)(F) of CERCLA, 42 U.S.C. § 9621 (f)(I )(F), EPA notified the State of North Carolina (the "State") on September 4, 2002, of negotiations with the potentially responsible party regarding the implementation of the remedial design and remedial action for the Former Landfill No. I, and EPA has provided the State with an opportunity to participate in such negotiations and be a party to this Consent Decree. D. In accordance with Section 1220)(1) of CERCLA, 42 U.S.C. § 96220)(1 ), EPA notified the United States Fish and Wildlife Service (US FWS) and the National Oceanic and Atmospheric Administration (NOAA) on September 4, 2002, of negotiations with the potentially responsible party regarding the release of hazardous substances that may have resulted in injury to the natural resources under Federal trusteeship and encouraged the trustees to participate in the negotiation of this Consent Decree. E. Ttie defendant that has entered into this Consent Decree ("Settling Defendant") does not admit any legal conclusions, fault or liability to the Plaintiff or to any other p;rson or en.tity arising out of the transactions or occurrences alleged in the: complaini, nor does it acknowledge that the release or threatened release of hazardous substances at or from OU I constitutes an imminent or substantial endangerment to the public health or welfare or the environment. F. In response to a release or a substantial threat of a release of a hazardous substance(s) at or from the Site, the Settling Defendant, commenced on March 24, I 998, a Remedial Investigation and Feasibility Study ("Rl/FS") for the Site pi.:rsuant to 40 C.F.R. § 300.430. This Rl/FS encompassed three source areas, including: (I) the Former Landfill No. I, and the soils, groundwater, and surface water impacted by the Former Landfill No. J, (2) the Former Chlorine Plant, and soils, sediments and groundwater impacted by that plant, and (3) the sediments and surface water contained in· Welch Creek and associated wetlands .. For the purposes of this Consent Decree, these three source areas will be considered three Operable Units . ("OUs"), and the Former Landfill No. I, which is the subject of this Consent Decree, is termed "OU!". G.

Pursuant to Section 117 of CERCLA, 42 U,S.C. § 9617, EPA published notice of the completion of the FS and of the proposed plan for remedial action for OU I on March 27, 2002, in a major local newspaper of general circulation. EPA provided an opportunity for • written and oral comments from the public on the proposed plan for remedial action. A copy of the transcript of the public meeting is available to the public as part of the adrninistrative record upon which the Regional Administrator based the selection of the response action. I. The decision by EPA on the remedial accion to be implemented for OU! is· embodied in a final Record of Decision ("ROD"), executed on June 19, 2002, on which the State has given its concurrence. The ROD includes a responsiveness summary to the public comments. Notice of the final plan was published in accordance with Section 1 I 7(b) of CERCLA. J. Based on the information presently available to EPA, EPA believes that the Work will be properly and promptly conducted by the Settling Defendant if conducted in accordance with the requirements of this Consent Decree and its appendices. K. Solely for the purposes of Section l 13(j) of CERCLA, the Remedial Action selected by the ROD and the Work to be performed by the Settling Defendant shall constitute a response action taken or ordered by the President. L.

The requirement that the Settling Defendant exercise "best efforts to fulfill the obligation" includes using best efforts to anticipate any potential force majeure event and best efforts to address the effects of any potential force majeure event (I) as it is occurring and (2) following the potential force majeure event, such that the delay is minimized to the greatest extent possible. "Force Majeure" does not include financial inability to complete the Work or a failure to attain the Performance Standards. 59. If any event occurs or has occurred that may delay the performance of any obligation under this Consent Decree, whether or not caused by a force majeure event, the Settling Defendant shall notify orally EPA's Project Coordinator or, in his or her absence, EPA's Alternate Project Coordinator or, in the event both ofEPA's designated representatives are unavailable, the Director of the Waste Management Division, EPA Region 4, within ten days of when Settling Defendant first knew that the event might cause a delay.

If EPA agrees that the delay or anticipated delay is attributable to a force majeure event, the time for performance of the obligations under this Consent Decree that are affected by the force maje'.lre event will be extended by EPA for such time as is necessary to complete those obligations. EPA will consider extending the delay of the performance of the obligations affected by the force majeure event by not less than the actual duration of the delay caused by the force majeure event.
