For more technical information, p!e~e review the documents in the infq_rmation repos~ory. · INTRODUCTION The Jadco-Hughes Superfund Site it located in an unincorporated area between the cities of Belmont and ML.Holly on Casori Street (North.Belmont) .. The Site is approximately six acres in size and is located in an area of residential and industrial land use. Aerial photographs indicate that the Site was farmland until the late· 1960s and was subsequently used for a solvent reclamation and . waste storage facility until 1975. The majority of the Site is revegetated. Remnants of the facility include: a fence (now replaced with an 8-ft high barbed wire fence), a truck unloading area, a corforete pad, culvert and building remnants. The Site itself is relatively flat; land south and east is wooded and undisturbed; west is industrial; and north is private residences. REMEDIAL DESIGN/REMEDIAL ACTION . Both the Remedial .Design (RD) and Remedial Action (RA) Reports were submitted in 1994 for EPA approval. After specific changes were made to the documents and an ESD was issued, both EPA and the North Carolina Department of Environment, Health & Natural Resources approved the RD/RA in September 1995. The Remedial Design is a blueprint of the technologies to be used to treat the contaminated soil and groundwater. The Remedial Action is the implementation, construction and· operation of the treatment technologies. -The Steering Committee representing the various responsible parties hired the firm Conestoga-Rovers & Associates to develop the Remedial Design and Remedial Action reports. Bid documents were sent ourto contractors for bid in October 1995. Metcalf& Eddy (M&E) was awarded the contract for Site remediation on December 22, 1995. M&E in turn selected three subcontractors to assist in the construction of the design. The following information is. to provide the public with more information about these two reports, and what to expect at the Site as activities get underway ..

The Potentially Responsible Parties' contractor, Conestoga-Rovers & Associates, has conducted more investigative activities as part ot the pre-Remedial Design as well as conducted a Treatability Study on both groundwater and soil to detennine it the selected remedies ot soil vapor extraction and groundwater pump-and-treat with activated carbon adsorption wculd be effective. This update provides a brief report on these findings. PRE-REMEDIAL DESIGN ACTIVITIES The scope of the pre-Remedial Design investigative activities inclt.ded the following: a geophysicaVmagnetometer survey was completed in April 1993 of the northern portion of the Site to supplement the subsurface investigations that were completed during the Remedial Investigation in this Area and the geophysical survey completed in the southern portion of the Site (9/90). A geophysical survey is similar to radar in it's purpose to determine what is in the distance that you cannot see, or similar to a depth finder in indicating what is beneath the surface of the water to a specific depth. The survey determined that it is unlikely that there are any buried metal objects such as drums or other containers in the area; an analyses of one round of groundwater samples from existing monitoring wells as part of the initiation of the groundwater monitoring program to verity Remedial Investigation data for the Remedial Design, and to assess the impact of silts and sediments on metals concentrations in groundwater analyses; the installation of five additional monitoring wells and six piezometers to characterize groundwater chemistry and aquifer hydraulics, and to establish the Site sentry monitoring system required by the selected remedy for the Site. [Piezometers are small-<liameter, non-pumping wells used to measure the elevation of the water table and rate of water flow in an aquifer]; and analyses of one round of groundwater samples from the new monitoring wells to characterize groundwater chemistry and aquifer hydraulics, and to confirm the vertical extent of groundwater contamination. The results of both groundwater and soil sampling taken during this pre-Remedial Design phase, for the most part, confirms the existence of pollutants discovered during sampling efforts of the Remedial Investigation in 1990. RESULTS OF TREATABILITY STUDIES A ·treatability study" is normally a small scale test of a treatment system either in a laboratory (bench scale) or on site (pilot) where small quantities of the contaminated soil/groundwater are run through the system to. detennine it the treatment method will acccmplish the clean up goals set in the Record of Decision. Groundwater: Utilizing the more common commercial extraction, aeration and aGuvated carbon adsorption treatment process tor groundwater proved to be successful (96%) in removing the majority of volatile organic compounds (YOCs). ·Figure 1 below is a generic illustration of how a groundwater pump-and-treat system might be set up; Figure 2 illustrates the groundwater and voe offi)as flow through a generic pump-and-treat system. {f,";, CJ Gel !'ill:al Bel <>----..-=~ .,..._ -..., ._,. ...,...... -· \\'atcr From Extraction Wells E1111.ilization Tank Figure 1 \'(IC <HT-(;as Treatment Figure 2 ( :arhon ,\fhorplinn llnit To Atmosphere lfo;char~c to POTW Soll: The soil vapor extraction (S.stem was set up on Site as a pilot study in the former landfill area, and was conducted to determine operational characteristics, desig, the off-gas treatment system and to assess the effectiveness of this technology.

Based upon the results of that investigation, the site was proposed for the National Priorities List and was finalized on that list in May 1986. The following is a flow chart of the major stages of the Superfund process which is lengthy and involved. Many factors effect the length of completion of all of the stages. As of this date we are in the Remedial Design stage. Once the designs have been completed, actual construction can begin on site and the treatment process can get underway. l!ilTt• Dl•oov--y NPL Ll..t.lng ~la.I ~•Tblll'C.Y I----I nv-t. 1 oat. 1 onl-----{ 11t ucty Pub I le: R.cord Coonnom. o~ 0-.C:T•Ton 1--.-{ ~,.1 0.-lgn Ren.dial A.ct. ran BRIEF SITE HISTORY AND BACKGROUND The Jadco-Hughes site is a six-acre, unincorporated area of North Belmont, approximately 12 miles west of Charlotte. (See Figure 1) The Site was originally a chemical storage and recovery facility which began in 1971 operated by C. A. Hughes, Inc., and was later leased to Jadco, Inc. in May of 1972. The business purchased used waste paint and ink-type solvents from area industries, then recycled the products to recover any useable portions for resale. Over one thousand 55iJallon drums containing many waste chemicals were stored on Site as well as waste chemical sludges resulting from the distillation process of the on-site recycling operation. Due to numerous spills and complaints by surrounding residents, and an order from the State of North Carolina for the business to cease operations, the Site closed in September of 1975. In addition, the State ordered the faciiity to be cleaned up. From 1975 to 1978 Jadco, Inc. and C.A. Hughes, Inc. complied with orders to clean up the Site by removing most of the drums, burying contaminated earth and debris in an on-site landfill located in the southwest comer of the property which was covered with clean soil and revegetated with grass, two in- ground pits into which solvents were placed were excavated. During 1983, the large storage tanks, and a mobile tanker and eight remaining drums were removed from the Site. The Site today is void of buildings/structures and only the concrete foundations remain. The EPA conducted site investigations in 1983 to determine the extent of contamination in suriace water, sediment, and groundwater. EPA conducted negotiations with the potentially responsible parties (PRPs) and an Administrative Order on Consent was agreed to by EPA and the PRPs in September 1986 in which they agreed to conduct the Remedial Investigation and Feasibility Study (commonly known as the RI/FS). Jadco-Hughes submitted their work plan for conducting the RUFS which was approved on September 27, 1988. A NOTE TO READERS, any time the potentially responsible parties conduct any work related to the Superiund process, EPA overviews their activities. ~ I I ; \l O 50 1000 1 I 1 1 " I LJ...J===J ---,;=,'==-'<=====----===-~'±i==-=-=-=-== =~:;;;,,:;==;;:;:;,;;:;::;:=.:~~=======+-==:;1---Ll:_ CASON STREET s.R.

Records indicate that 500 pounds of magnesium was also stored on Site. Once the Remedial Investigation and Feasibility Study were completed, the Agency prepared a Proposed Plan in July 1990 informing the public of the findings of these two activities. A public meeting was held on July 26, 1990, to provide citizens with a more detailed presentation of the data of what had been discovered at the Site, what the Agency was proposing to do, aoo to provide the public with an opportunity to ask questions and state their concerns. After the 30-<lay comment period ended on August 24, 1990, a review was conducted of all comments received aoo documents developed during the process concerning treating contamination at the Site. A Record of Decision was prepared and signed on September 27, 1990, selecting the preferred treatment remedies. The selected remedies were: soil vapor extraction and soil flushing for treating the contaminated soil; extraction of groundwater and treatment by carbon adsorption aoo once the contamination is removed from the groundwater it would be discharged into a local publically owned treatment works (POTW). There are ~o POTWs ~he area: Belmont aoo Mt. Holly. However, the City of Belmont's POTW would require upgrading before it could accept the additional treated water from the Site because the facility is already operating at full capacity. The Potentially Responsible Parties are presently negoiiating with the City of Mt. Holly for permission to discharge the treated groundwater to their POTW. If the pretreated groundwater cannot be released into a POTW, it would be · ireated by Ultra Violet-Oxidation· and then discharged into the tributary that flows into Fites Creek. · Surface water presently draining across the Site will be diverted to avoid continued contamination by surface soil. Since that time, all of the behind-the-scene activities have been occurring. First, lengthy negotiations with the Potentially Responsible Parties were conducted in order to reach an agreement with. them for them to design the selected alternative and assume responsibility for costs. The period of negotiations ended on May 30, 1991. Since no agreement was reached, EPA issued a Unilateral Administrative Order against the Potentially Responsible Parties in June 1991 ordering them-to conduct the Remedial Design and Remedial Action stages of the process. Since issuance of the Order, the Potentially Responsible Parties have been working on the Remedial Design stage aoo conducting additional field work. A Treatability Study of the "soil vapor extraction" remedy was conducted in May 1993, as well as bench scale treatability work on the selected groundwater remedy. EPA is awaiting the results of the treatability studies before the full-scale treatment is implemented. BRIEF DESCRIPTION OF SELECTED REHEDIES For soil remediation a combination of soil vapor extraction aoo soil flushing were s·elected. The soil contamination at this Site has been found to be largely organic in nature. Placing air vents into the ground at strategic points and forcing air into the ground would force a separation of organic compounds from the soil. The contaminated air stream corning from the air vents would then be filtered through activated carbon units to purify the air before discharge into the atmosphere. The carbon units function • like the carbon filter used in aquariums. Soil flushing is similar. to vapor extraction in that water is forced into the soil through infiltration wells. This contact of water with soil transfers contamination from soil to water. The contaminated water is then collected for treatment. This. technology would require concurrent operation with a groundwater extraction system, ·-. ·,. For groundwater, the selected remedy was to extract and treat contamination in the groundwater by an activated carbon adsorption process. Extraction wells and a tile drain system will be placed at designated locations either in or around the plume of contamination, and the groundwater will be pumped r. out of the .nd. This water will then flow through pipes into a treatment system containing carbon adsorption units which will remove the contaminants. The treated groundwater will either be discharged into a local POTW or into the tributary adjacent to the pr~rty. · Monitoring of both treatment processes ai°lhe Site will be conducted on a quarterly basis, as well as a·review of the groundwater treatment system performed every five years.

PR~~ Gaston County, North Carolina REGION IV June 1991 INTRODUCTION: The United States Environmental Protection Agency completed a Remedial Investigation/ Feasibility Study (RI/FS) in September 1990. Based on the results of the study, EPA selected a remedy that provides protection of public health and the environment. The remedy \vas published in the Record Of Decision (ROD), September 27, 1990. The next steps in the Superfund process are the Remedial Design/Remedial Action , (RD/RA). The Remedial Design is defined as the development of all engineering plans and specifications necessary to begin actual cleanup at a site. · Once all plans are approved, i.e., Health and Safety Plans, Quality Assurance Plans, Con- struction Permits, if necessary, then Remedial Action, or the actual construction of necessary treatment facilities can begin. Inspection of all equipment occurs prior to the implementa- tion of the process or the cleanup. This fact sheet describes the Remedial Design/ . Remedial .A. .. ction process as it relates to the Jadco-Hughes Site. SITE BACKGROUND AND HISTORY: The Jadco-Hughes Site is located in an unin- corporated area of North Belmont, Gaston County, North Carolina. The six-acre Site is a former solvent reclamation and waste storage facility operated by C. A. Hughes, Inc. from SUPERFUND PROCESS -ihliiii@&-41 ii&&► COMMUNITY RELATIONS i ewes+s&&\¥&13115 iiifli.t • 1971 to 1975 and later leased to Jacdo, Inc. until operations were suspended and conse- quently ended in 1975. Aerial photography in- dicates that the facility was active as early as 1969. During its operation, the Site reclaimed used waste paint and ink-type solvents. It also stored drummed materials consisting of many waste chemicals and chemical waste· sludges. · MAJOR CONTAMINANTS TO BE TREATED AT SITE Vinyl Chloride Toluene 1,2 Dichloroethane Chloroform Carbon Tetrachloride Acetone The State of North Carolina ordered the Site to be closed in 1975 after complaints by neigh- boring residents and the occurrence of chemi- cal spills between 1971 and 197 5. In addition, the State ordered the facility to be cleaned up and, along .with EPA, pursued proper management of the cleanup under ex- isting State and Federal laws. Reportedly, the cleanup included the excavation of two pits which were used to store solvents. These sol- vents were allowed to percolate into the ground. Also, on-site contaminated surface • 1.-·-·-·-·-~---'.-. ·-·-· 'Cl'affyVllle .. :, • ,. -9lanlty • . ~ ·--. 0 ' . -t . "'\ Dal~ . Mt. Hol~ · \ Beuema, JAOCO-! \ •• Cltyo e . .

Additionally, the remaining large storage tanks, a mobile tanker, and eight remaining drums were removed in 1983. · In 1983, the.EPA initiated a Superfund Site investigation. The Jadco-Hughes Site was ranked and finalized on the National Priorities List (NPL) in 1986. The first step in the Superfund process is to conduct a Remedial Investigation/Feasibility Study (RI/FS). EPA negotiated with the various fmns that had conducted business with Jadco, Inc. and C. A. Hughes, Inc. to perform the Remedial Investigation/Feasibility Study. In September 1986, an Administrative Order on Consent was signed by EPA and the. Potential Responsible Parties (PRPs). The Ad- ministrative Order outlined the terms under which EPA would allow the PRPs to conduct the Rl/FS. The Remedial Investigation was completed in the Summer of 1990. The RI confmned that contaminated soil and groundwater are present at the Site. The ... groundwater is believed to be slowly migrat- ing in a northerly direction from the Site. In the later part of 1990, the PCB removal was completed. 2 The extension of the public water line was in- stalled to provide an alternate water supply to • potentially affected residents. This water line extension was provided by local officials. The RJ/FS are available to the public in the Gaston County Public Library Repository. A public meeting to present a summary of the RJJFS process and to explain the proposed remedies was held on July 26, 1990 .. This··· public meeting initiated a three week public comment period in which the public was en- _ --PFIQPCRl'f U"f ---PAOPOSCD POIM-.NOH f'EMCE -* - - .. -~~ I[MP()A.-.Rl' Jl:t.CE • couraged to review the proposed remedies and respond to EPA. 'EPA prepared aR~ord of Decision (ROD) . taking into consideration comments from the .. public and the results of the RJJFS: The ROD (available to the public in the Gaston County Public Library"Repository) specified the ' Remedial Action selected for the Jadco- Hughes Site. :loO 100rt L--- I -• I .. 0 . .

The major components of the selected remedy include: • Institutional controls and/or other land use restrictions; groundwater monitoring; • Groundwater recovery via extraction wells and tile drain(s); • Groundwater treatment via aeration and carbon filtration to pretreatment standards; • . disharge of treated effluent to the Belmont PO1W; • Treatability studies to ensure compliance with PO1W pre-treatment standards; • Backup discharge plan; • Soil vapor extraction followed by carbon adsorption of removed vapor; • Soil flushing by introduction in con- taminated water; • Replacement of onsite culvert; • Redirection of spring water flow; 4 • • Monitoring of the Site, it includes groundwater, surface water, sediments, and soils; and • Review of groundwater use every five years. In the event the P01W d_oes_ not agree to ac- cept the groundwater discharge, a contingency alternative has been selected. This alternative will not vary significantly from the selected remedy. CURRENT STATUS OF THE SITE: The period of negotiations for Remedial Design/Remedial Action between the EPA and PRPs Steering Committee began on December 30, 1990. The period of negotia- tions ended on May 30, 1991. Since the Steer- ing Committee has not signed the Consent Decree the EPA issued a Unilateral Ad- ministrative Order which becomes effective in June 1991. This document orders the PRPs to perform the Remedial Design/Remedial Ac- tion. Jf the PRPs decide not to do the work, EPA may undertake these activities and pur- sue civil litigation against the parties for reim- bursement of Site expenditures. COMMUNITY RELATIONS: Community relations are vital to the Super- fund process. Citizen involvement is stressed in the Code of Federal Regulations governing Superfund site activities, Since the Jadco- Hughes Site was finalized on the National Priorities List in 1986, EPA has conducted in- terviews with residents of the area, local and state officials, and other interested parties; provided site information fact sheets; held public meetings; published information in the newspapers; provided public comment ... -·-,- • • periods on major site activities; responded to to $50,000 to one incorporated, non-profit .. citizen comments/concerns and established an group at a site to"hire technical advisors to information repository at the Gaston County help them understand existing information .. _ ..

Remedial Investigation -An in-depth study designed to gather the data necessary to deter- mine the nature and extent of contamination at a Superfund site; establish criteria for clean- ing up the site; identify preliminary alterna- tives for remedial actions; arid support the technical and cost analyses of the alternatives. The Remedial Investigation is usually done with the Feasibility Study. Together they are usually referred to as the "RI/FS." Superfund -The program operated under the legislative authority of CERCLA and SARA that funds and carries out the EPA solid waste emergency and long-term removal remedial activities. These activities include estab- lishing the National Priorities List, investigat- ing sites for inclusion on the list, determining their priority level on the list, and conducting and/or supervising the ultimately determined cleanup and other remedial actions.

This fact sheet describes the Remedial Investigation/ Feasibility Study (RI/FS) findings and the proposed plan for cleaning up contamination at the Jadco-Hughes Superfund Site. Gaston County, North Carolina. This fact sheet identifies the three remedial measures EPA considered as well as the preferred alter- native and the rationale for its selection. In ad- dition, the fact sheet provides a brief back- ground and history of the site, and identifies ways in which the public may become involved in the corrective process at the Jadco-Hughes SI!e. Words highlighted in bold print are defined in the glossary on page eight and nine of this fact sheet. A list of acronyms appears on page seven. Site Background and History The Jadco-Hughes site is located in an unin- corporated area of North Belmont, Gaston County, North Carolina. The six-acre site is a former solvent reclamation and waste storage facility operated by C.A. Hughes, Inc. from 1971 to 1975 and later leased to Jadco, Inc. until operations were suspended and conse- quently ended in 1975. Aerial photography indicates that the facility was active as early as 1969. During its operation, the site re- claimed used waste paint and ink-type sol-.. vt:nts. It also stored drummed materials con- sisting of many waste chemicals and chemical waste sludges. The State of North Carolina ordered the site to be closed in 197 5 after complaints by neigh- boring residents and many spills between 1971 and 1975. In addition, the State ordered PUBLIC MEETING ON RI FINDINGS Public Meeting for the Jadco Hughes Superfund Site A public meeting will be held to present results of the Remedial Investigation for the Jadco Hughes Supertund site. _The purpose of the meeting is to p-ovide lhe community 'Mth an opportunity to discuss the site status with representatives from EPA.

Reponedly, the cleanup included the excava- tion of two in-ground pits into which solvents were placed. Also, on-site contaminated surface soil was consolidated and covered in an on-site landfill located in the southwest corner of the site in 1978. Additionally, the remaining large storage tanks, a mobile tanker, and eight remaining drums were removed in 1983. In 1983, the EPA initiated a Superfund site investigation. This investigation analyzed surface water, sediment, and ground-water samples. The data collected were evaluated using the Hawrd Ranking System (HRS). The resulting HRS score was 42.00 and re- flected the potential for ground-water and surface water contamination. As directed by the Comprehensive Environmental Re- sponse, Compensation, and Liability Act (CERCLA or Superfund), EPA placed the Jadco-Hughes site on the National Priorities List (NPL) in 1986. EPA negotiated with the various firms that had conducted business with Jadco, Inc. and C.A. Hughes, Inc. to perform the RI/FS. In Septem- ber 1986, an Administrative Order on Con- sent was agreed upon by EPA and the poten- tially responsible parties (PRPs). The ad- ministrative order outlined the terms under which EPA would allow the PRPs to conduct the RI/FS. Results of the Remedial Investigation During the RI, EPA identified contamination present in surface water, sediment, soil, and groundwater using a variety of sampling tech- niques and ground-water monitoring wells. The principal site contaminants include vola- tile organic compounds (VOCs), extractable organic compounds which are sometimes referred to as BNAs; polychlorinated biphen- yls (PCBs), and metals. Areas of soil contami- nation include the landfill, former operations area, the former nonh and south solvent pits, and the southeast swale area of the site. The presence of VOCs was detected in the soil of the operations area as well as the pits. The southeast swale area was found to be contami- nated with PCBs in the top three to ten inches of soil. Page 2 Ground-watLples revealed that on-site ground-water contamination was also present and included VOCs, BNAs, and some metals. In the area immediately surrounding the site, ground-water monitoring wells showed con- centrations of the principal contaminants. Testing of residential wells 100 to 1,000 feet downgradient of the site found contamination but at levels below drinking water standards. The ground water is believed to be migrating in a nonherly direction from the site. The RI also identified surface water contami- nation by VOCs. This may be the result of surface water runoff from the site and/or the discharge of contaminated groundwater to the on-site culven and to tributaries of Fites Creek. The RI confirmed that the buried culven on- site is damaged. Risk Assessment uio As a result of the RI of the J adco Hughes site, EPA has concluded that the major risk to public health and the environment would result from ingestion of contaminated ground water. The extension of the public water line was installed to provide an alternate water supply to potentially, affected residences. This water line extension was provided by local officials. For further information on the risks posed by the contamination at the Jadco Hughes site can be found in the Feasibility Study, Superfund Risk Assessment and the Risk Assessment Fact Sheet at the information repository listed on page 7. Remedy Selection EPA evaluated the remedy for the Jadco- Hughes site based upon the following primary objectives: • Overall protection of human health and the environment • Compliance with ARARs • Long-term effectiveness and perma- nence • Reduction of toxicity, mobility or volume through treatment • Shon-term effectiveness • JADCO -HUGHES s'uPERFU, SITE FORMER MOBILE TANKER LOCATION LANDFILL AREA 1--l!J w a: lii· z 0 (/) <( () POSSIBLE BURIED DRUMS-----1--JLJ N CONCRETE PAD SPRING FORMER BULK STORAGE TANKS LOCATION FORMER LOCATION OF DISTILLATION EQUIPMENT 0 100 200 --L--I SCALE IN FEET ,-·-·-·-·--·-·-·-·-·-· \, ~herryvllle ~'>,.

Interim Remedial Measures Before the permanent remedial measures begin, the PRP has proposed interim remedial measures for removing PCB contaminated soil that have been approved by. the EPA. Access to the site will be limited by an 8-foot high chain link fence and locked gates at the pe- rimeter of the site. A temporary fence will be constructed next to the property _to the east until PCB re-ation has been completed. PCB contaminated surface soil having concen- trations greater than 10 mg/kg will be removed from the southeast swa!e area of the site. The contaminated soil may be transported off-site for secure disposal or incineration. Summary of the Remedial Alterna- tives The PRPs proposed eleven potentially practical remedial alternatives for the Jadco-Hughes Site. EPA and the responsible parties then used a screening process to evaluate the poten- tially practical remedial alternatives, which were outlined in the Feasibility Study for the Jadco-Hughes site. The evaluations examined the effectiveness of such technologies as land SUPERFUND REMEDIAL/ENFORCEMENT PROCESS To understand the enforcement process, tt is necessary to understand the Superfund reme- dial process, which happens concurrently. Under the remedial program, EPA takes long- tenn cleanup actions to stop or substantially reduce releases or threats of releases of hazardous substances that are serious but not immediately me-threatening. Removal actions - -shcrt-tenn actions intended to stabilize or clean up a hazardous incident or stte that poses an immediate threat to human health or wettare or the environment --may be taken at any point in the remedial process. The remedial process begins wtth a Preliminary AssessmenUSite Inspection (PNSI). This usually is conducted by the State, to determine whether the stte poses a potential hazard sig- ntticant enough to warrant further study and investigation. The stte is then ranked using the HRS, a nu- merical ranking system used to identtty the stte·s potential hazard to the environment and public health. Sites assigned an HRS score of Page 4 28.5 or above are added to the NPL. Next, a RI is oonducted to assess the extent and nature of the oontamination and the potential risks. In conjunction wtth the RI, a FS is pre- pared to examine and evaluate various remedial attematives. Following a public comment period on EPA's preferred alternative and the draft FS report, EPA chooses a specific cleanup plan and outlines the chosen remedy in the Record of Decision (ROD). Once the Remedial Design (RD) (which includes engineering plans and specttications) is com- pleted, the actual stte cleanup, or Remedial Action (RA) can begin. After RD/RA activities have been completed, the stte is monttored to ·ensure the effectiveness of the cleanup. Certain measures require ongoing operation or periodic maintenance. This is called the operation and maintenance phase. disposal, soil treatme.ater treatment, and physical containment. Of the eleven alterna- tives, three remedial alternatives were identi- fied as possible response actions for addressing the contaminated sediment/soil and ground water/surface water at the site. Each of the three alternatives for remedial action at the site is briefly summarized below, Further explana- tion of the alternatives may be found in the FS, a copy of which is located in the Administra- tive Record at the information repository. Alternative 1 -No Action CERCLA requires that the no-action alterna- tive be considered. This alternative is included to provide the basis for comparing existing site conditions with conditions that would result after the implementation of the other proposed alternatives. The no-action alternative assumes that the site cleanup completed in 1983 and the interim remedial actions proposed by the PRPs are adequate responses to the conditions existing at the site. Under the no-action alter- native, no measures would be taken to address the leaching of contaminants from the soil to ground water. The contaminated ground water would continue to migrate from the site as well as potentially discharge into the tributaries of Fites Creek. Alternative 2 -Soil Vapor Extraction and Soil Flu shin&, Groundwater Extraction, Treatment and Dischar&e (Three Various Dischar&e Options, Deed/Access Restriction, Culvert Removal. Surface Water Diversion, and Moni- .1.Qij_ng This alternative would involve the construction of a soil vapor extraction (SVE). and a soil flushing system of the landfill and the former operations area. This system operates by installing vertical vents into the contaminated soil above the water _table. Air is then forced through one set of vents and vacuumed through the soil. The extracted air would be filtered through an activated carbon adsorp- tion system. Uncontaminated water would be flushed through the soil and collected by a drainage system. The collected water would be treated in a ground-water treatment system. Ground-water extraction for the site would use extraction wells located in areas of significant ground-water contamination. The ground- water treatment system would remove volatile organics from the ground-water stream. After VOC concentrations are reduced, the water would be dis.ged. Three discharge options are presented within this fact sheet. Additional remedial components include deed and access restrictions, culvert removal, sur- face water diversion, and monitoring. Deed re- strictions prevent or restrict the use of the property and make prospective purchasers aware of the property's history. Access restric- tion to the site involves building a fence around the property to prevent trespassing. The removal of the culvert will eliminate ground-water discharge to the tributary via the culvert. The final remedial component in- cludes monitoring programs for ground water and surface water. The Present Worth Cost of Alternative 9 is $4,715,900.* Alternative l I -On-Site Soil Incineration. Groundwater Extraction. Treannent and Dis- char&e, Deed/Access Resnictions, Culvert Re- moval. Surface Water Diversion, and Monitor- mg This alternative combines the same ground- water remedial measures, deed/access restric- tions, culvert replacement, and monitoring as identified in Alternative 9 with on-site incin- eration and replacement of the soils from the landfill and former operations area. The difference between the two alternative reme- dies is the method for decontaminating the soil and sediments. To decontaminate the soil and sediment under this alternative, a Circulating Bed Combustor (CBC) or an equivalent tech- nology would be used to perform on-site incineration. The on-site incinerator woul.d burn organic compounds at temperatures greater than 1500 degrees Fahrenheit Before using the decontaminated soil as backfill for the site, the soil would be tested for metals concentrations to determine whether it is suitable for use as backfill. Monitoring of surface and ground water will also be con- ducted. The Present Worth Cost of Alternative 11 is "$8,305,900. * Page 5 * Costs identified are rough estimates and are provided for a comparative basis Discharge Optiontl 1. 2. Local·POT\V Adjacent Stream 3. On-site Infiltration Preferred Alternative and Rationale for Selection EPA has selected Alternative 9 as the preferred method to clean up site contamination. The preferred alternative will be implemented through the use of soil vapor extraction and soil flushing, groundwater extraction and treatment and discharge, deed/access restric- tion, culvert removal, surface water monitor- ing, and monitoring. The rationale for select- ing Alternative 9 includes: • • Page 6 Consistent with National Contingency Plan a~ well as Section 121 of CERCLA Proven technology Achieves applicable or relevant and appropriate requirements, commonly • • • known as ARARs, and • Cost effective alternative . Community Role in the Selection Process · As required by CERCLA, EPA involves the public in the Superfund process. Before select- ing a remedial alternative, EPA will consider written or oral comments on the proposed plan from July 26, 1990 through August 24, 1990. Written comments on the RI/FS and the pro- posed plan can be submitted to: Ms. Barbara Benoy Remedial Project Manager U.S. Environmental Protection Agency Region IV 345 Courtland Street, NE Atlanta, GA 30365 (404) 347-7791 All public comments &e recorded and responded to in the Responsiveness Summary section of the Record of Decision (ROD)· for the Jacko Hughes site. The ROD is a legal decision document, prepared by EPA, which identifies the remedial action for the site. The ROD also describes the alternatives considered and the the rationale for selecting the chosen remedy. The selection of remedy will be made after full consideration of all public comments on the RI/FS and the Proposed Plan, and will be documented in the ROD: Community groups interested in interpreting the technical information presented in the RlJFS and other studies may be eligible for one grant of up to $50,000 in Federal funds. The purpose of the grant is to provide technical assistance for community residents seeking to understand site documents. Copies of the RIJFS and other information used in the the remedy seiection process are part of the Administrative Record for the site. The Administrative Record will be available to the public no later than July 23, 1990 at the information repository, which has been estab- iished at the following location: Gaston County Public Library Belmont Branch 111 Central Avenue Belmont, NC 28012 Page 7 • • . •·t<••c;LdsSARY r•••)•)•.•··••·• · ..

It explains what activities they will undertake to determine to what extent the site may still be contaminated and what additional actions may be needed. Site Description and History The Jadco-Hughes site covers approximately six acres out- side Belmont, North Carolina in Gaston County. There are two w,named tributaries on the site which flow into Fites Creek, which is itself a tributary of the Catawba River. Many of the residents living near the site currently rely on private well water, although there are plans to extend Catawba Heights Sanitary District water lines to many of the homes near the site. Originally owned and operated by C.A. Hughes, Inc., the facility was used as a chemical recovery plant, reclaiming ink and paint solvents, between 1971 and 1975. In addition, !lie company stored waste chemical sludges from a variety of businesses in the area along with sludge resulting from the recovery process. These sludges were stored on the site in both tanks and drums until 1977. In 1972, the facility was leased to Jadco, Inc., at which time approximately 8,000 to 10,000 55-gallon drums containing various chemical com- pounds were reponed to be at the site. Chemicals contained in these drums included ink and paint wash, chlorinated sol- vents, acetone, paint resins, waste oils and numerous other volatile organic compounds including benzene, toluene and xylene. Reponed problems at the site date back to 1973 when the chemical ally! ether spilled into one of the unnamed tributaries to Files Creek. In the following two years numerous other problems and violations of water quality standards were detected by the North Carolina Division of Environmental Management (DEM), and civil penalties were imposed. In mid-summer of 1975, approximately 50 barrels containing hazardous materials were washed as much as one mile downstream after heavy rains and flash flooding. After this incident, a temporary restraining order was issued by the General Coun of Justice, Superior Coun of Gaston County, requiring Jadco, Inc. to discontinue operations. In Septem- ber 1975, the Coun issued an additional order requiring SEPA REGION IV March 1987 Hughes, Inc. and Jadco, Inc. to remove all chemicals and drums from the site, and cease all reprocessing operations. By 1977, the majority of drums were removed from the site. On-site landfilling and revegetation were completed in 1978. Officials from EPA and the North Carolina Depan.."1ent of Health Services (OHS) pursued cleanup of the site under State water quality and hazardous waste disposal laws exist- ing prior to the passage of the Comprehensive Environmen- tal Response, Compensation and Liability Act (CERCLA-- commonly known as Superfund) in 1980. In 1982, OHS recommended to EPA that the site be addressed under CERCLA regulations. EPA Region IV officials conducted a site inspection at the Jadco-Hughes site in 1983. This infor- mation was used by EPA to determine the site's Hazard Ranking Score (HRS-a numerical ranking system used to identify the site's potential hazard to the environment and public health). Subsequently, in October 1984, the Jadco- Hughes site was added to EP A's National Priorities List (NPL) of hazardous waste sites identified for cleanup under the Superfund program. The Superfund Enforcement Process With the passage of CERCLA in 1980, Congress gave EPA the authority to compel potentially ·responsible parties (PRPs) to clean up hazardous waste sites that may endanger public health or the environment through actual or threatened releases of hazardous substances. PRPs may be any one of the following:' • Generators of the waste (those who produced the wastes); • Any party who contracted for treatment, trarisport, or dis- posal of the wastes; Past or present owners or operators of the site. Wherever possible, EPA attempts to have the PRPs conduct the site studies and cleanup work. The· actions that EPA takes to compel PRPs to study or clean up a site are collectively called the enforcement process. Hazardous waste sites with conditions serious enough to be ranked for inclusion on the National Priorities List (NPL) Page 1 .. , • are given priority by EPA for pursuing enforcement actions and may also qualify for Federal funds for cleanup. EPA calls upon the PRPs to conduct the site studies called the remedial investigation and feasibility study (RJ/FS) and, if needed. the actual cleanup of the site. The Jadco-Hughes Coment Order An Administrative Order on Consent (Consent Order) for the Jadco-Hughes site became effective on September 30, 1986. It was signed by EPA and twelve companies named as WHAT IS A REMEDIAL INVESTIGATION? A remedial investigaton (RI) is an intensive study of a Superfwid site. It is carried out by a team ofbealth and envi- ronmental specialists such as hydrogeologists, engineers, and biologists to determine the exact na111re of the hazardous waste contamination, the nalllre of any actual or potential threat that may be posed to human bealth or the environ- ment and the bowidaries or extent of any contamination that is fOWld at a site (see Page 4 for a condensed description of the Superfund cleanup and enforcement processes). Typically, the RI report will desaibe the type and extent of onsite and off site contamination, effects of contamination on surface water and growid water, and the degree of contamina- tion in the soil. To achieve these findings, contractors hired by the potentially responsible parties (PRPs) will take sam- ples of the soil and water at various locations at the site. All work will receive EPA oversighL In addition to records compiled from earlier sampling at the Jadco-Hughes site, the RI will include results from systematic sampling of surface and grolllld water and soil, and will further include data taken from additional monitoring wells on the Jadco-Hughes pro-. poty. Samples will be sent to laboratories meeting EPA standards to be analyzed for various contaminants. The site will also be studied to determine whether or not the contaminants are moving through the land or water, where they might go, and what sensitive areas they might reach. Based on this infor- mation, an estimate of the contaminants' potential impact on human health and the environment will be developed in a study known as a risk a•sessrnent ..•.. , .. WHAT IS A FEASIBILITY STUDY? Once the RI is completed, the information is used to develop a feasibility study (FS). During the feasibility study, envi- ronmental engineers and other teclmical staff consider, · descnbe, and evaluate options for cleaning up the site. As required by the Superfund program, the feasibility study team designs cleanup alternatives so that each of the following criteria is met by at least one of the alternatives. (In some cases an alternative may fit more than one crite- rion.) A feasible alternative will: Page 2 • potentially responsible parties (PRPs) because they alleg- edly generated wastes that were shipped to the Jadco-Hughes site. The Consent Order is the agreement that was reached as a result of negotiations between EPA and the PRPs in accordance with CERCLA. It identifies the joint responsibilities of the twelve companies in conducting the remedial investigation /feasibility study (RI/FS). Under the terms of the Consent Order, the PRPs must sub- mit to EPA a work plan for conducting the RI/FS. Titls work plan must include: a sampling plan; a health and safety • Meet applicable or relevant and appropriate State and Federal public bealth or environmental standards; • Exceed applicable and/or relevant Federal public heal th or enviroomental standards; • Reduce any present or potential threat from hazardous substances or contaminants without meeting applicable or relevant public bealth or environmental standards; • Involve offsite treatment or disposal. In some cases, the FS will recommend that no action is nec- essary. Each proposed alternative must be evaluated based on the following criteria: • Technical feasibility (reliability, ease of implementa- tion, and quality of performance); • Impact on the environment during and after implementation; • • • • • Impact on public health; Instirutional considerations (conformity with Federal, State and local regulations and standards); and Whether it significantly reduces toxicity, mobility or volume of hazardous substances; Whether it utilizes treatment as the principal element of the remedy; Whether it utilizes permanent solutions and alternative technologies or resource recovery technologies to the maximum extent practicable; • Cost-effectiveness. The FS presents all the alternatives and how they rate according to the above criteria. It may also recommend a sin- gle or several alternatives as the best solution. • SUPERFUNO PROCESS • ENFORCEMENT ACTIVITIES Site Discovery 3 REMOVAL AND COMMUNITY RELATIONS ACTIVITIES In 1980, Congress enacted the Comprehensive Environmen- tal Response, Compensation, and Liability Act (CERCLA, more commonly known as "Superfw,d"). In 1986, Congress reauthorized the Superfw,d program w,der the Superfw,d Amendments and Reauthorization Act (SARA). This act authorizes EPA to respond to actual or threatened releases of hazardous substances that may endan- ger public health or welfare, or the environmenL Titis exhibit providesta simplified explanation of how a long-term Superfw,d response works at sites like the Jadco- Hughes site. I. After a site is discovered, it is "investigated,• usually by the State. 2. The State then ranks the site using a system that takes into account Possible threats to the hwnan population. • 1 Potential hazards (e.g., from direct contact, inhalation, fire, or explosion) of substances at the site. • Potential for the substances at the site to contaminate drinking water supplies. Potential for the substances at the site to pollute or otherwise harm the environmenL If the problems at a site are deemed serious by the State and EPA the site will be listed on the National Priorities List (NPL), a roster of the nation's worst hazardous waste sites. Every site on the NPL is eligible for Federal Superfund money. 3. Next, a "remedial investigation" (RI) is done. The RI assesses how serious the contamination is, what kind of contaminants are present, and characterizes potential risks to the community. As part of the RI. a risk assessment is typically done that describes the problems at the site and the potential health and environmental consequences if no further action is taken at the site. 4. Following completion of the RI, EPA performs a "feasibility study" (FS) which examines various cleanup Page4 alternatives and evaluates them on the basis of technical fea- sibility, public health effects, environmental impacts, insti- tutional· concerns (including compliance with state and local laws), impact on the commw,ity, and cost. The find- ings are presented in a draft FS report. 5. Following completion of the draft FS report, EPA holds a "public comment period" to receive citizen com- ments concerning the recommended alternatives. Citizens may provide comments either orally at public meetings or through written correspondence to EPA. 6. After public comments have been received, EPA then chooses a "specific cleanup plan." 7. Once the design is finished, the actual remedial activities at the site can begin. The time necessary to complete each of these steps varies with every site. In general, a "remedial investigation/feasi- bility study" takes from one to two years. Designing the cleanup plan may take six months. Implementing the rem- edy--the actual containment or removal of the waste--may take from one to three years. If grow,d water is involved, the fmal cleanup may take many more years. If a site or any portion thereof poses an imminent threat to public health or the environment at any time, EPA may conduct an emergency response referred to as "removal activities." "Enforcement activities" refers to those actions taken by EPA at Superfw,d sites to get those responsible for the hazardous waste sites to conduct the site studies and cleanup, and/or pay for them. "Ongoing community relations activities" during a cleanup include public meetings and other activities intended to keep citizens and officials informed and to encourage public participation. These activities are scheduled throughout the course of the remedial cleanup process. Specific activities vary from site to site depending on the level and nature of concern. The range of commw,ity relations activities that can occur is described in EP A's Community Relations Plan for the site. • plan; a community relations plan; a plan for satisfying any permining requirements; a description of chain of custody procedures (which ensure that samples are properly identified and handled); and a description of quality control and assur- ance procedures. They also must designate a project coordi- nator who will be responsible for communications with EPA; provide EPA with monthly progress repons, including the results of any sampling and tests; and prepare prelimi- nary and final reports for EPA according to the schedule out- lined in the work plan. Public Comment Period Once the draft feasibility study (FS) is completed, it is released to the public. A three week public comment period will then be held to allow citizens to comment on the reme- dial alternatives considered in the FS. A public meeting may also be held. INFORMATION REPOSITORY EPA will establish an informa- tion repository that will contain the RI report and draft FS, as well as other public documents on the site. The repository will be located at the: Gaston Cowity Public Library Belmont Branch 111 Central Avenue Belmont. NC 280 I 2 Librarian: Helen Jones (704) 825-5426 • Current Status of the Site A work plan has been submitted to EPA's Region IV office and is currently wider review. Once approved, the PRPs will begin conducting the RI/FS. Next Steps If additional cleanup activities are needed at theJadco-Hughes site, EPA may initiate negotiations for the cleanup with the twelve parties to the Consent Order and any others who may have been involved in the site. If an agreement is reached, the method and terms of cleanup will be outlined in a con- sent decree enforceable by a court. When the companies conduct the cleanup, they must do so in accordance with the consent decree and will be subject to EPA oversight. If an . agreement with the PRPs cannot be reached, EPA may pur- sue legal action in order to have these or other PRPs per- form the work. EPA may also use Superfwid trust monies to conduct the cleanup and then sue the PRPs to recover EP A's costs.
