Section 1.0Overview of the C'ommunitv Involvement Plan

Tlie Ihiited States Environmental Protection Agency (EPA) developed the Community Involvement Phin (CIP) to serve as a framework for community involvement and outreach etToils associated with the Cabot Carbon Koppers Superfund Site (the Site). Tlie CIP addresses the relationship between the Site, the community, and EPA: provides a background of the community: presents EPA's community involvement program: and provides a listing of resources. Tlie goals of the CIP iu*e to infonn the public of planned and ongoing Site activities: maintain open communication about Site remediation: ensure that concerns are acknowledged and addressed: provide interested pmlies with useful inlbnnation: provide citizens with opportunities to comment on and be involved in technical decisions: iind encourage and assist local citizens in providing input to agency decisions that will have long-tenn elTects on the community. Inlbnnation discussed during community interviews and Site documents are both essential elements in developing the CIP.

Tlie CIP is revised as community concern wiUTiints or at minimum, even three years until Site activities have been concluded. Tlie revision process includes conducting additional community interviews, updating mailing lists, investigating the designated repositon. and updating the contacts iind resources provided in the .Appendices of the CIP. Tlie puipose of the revision process is to ensure that both previous iind cuirent needs and expectations specified by the community are acknowledged.


Section 2.0C'apsule Site Description

2.1 Site History

In 1916. a carbon iind wood-treating tacility began operation at the Site. The Site is located at Main Street and 23"^^' Avenue in Gainesville, a town in Alachua County. Florida. Soil and groundwater contamination at the Site was discovered in the mid-1980‘s by the Florida Depiulment of Environmental Protection. .An initial remedial investigation feasibility study was conducted by Cabot Carbon and Beazer East, the Koppers Site responsible party. Tlie initial Record of Decision was issued in 1990.

Tlie Site is made up of two properties, the Cabot CiU'bon property and the Koppers property. Tlie Koppers property includes the area where a wood-treating tacility operated between 1916 and 2009. The Cabot CiU'bon property includes the area where a charcoal and resin production tacility operated. The EP.A placed the Site on the Superfund Program's National Priorities List (NPL) in 1984 because of contaminated soil and groundwater.

In 1990. the EP.A issued a cleanup plan for the Site. Tins phin included digging up and treating contaminated soil from the Koppers area of the Site. It also included placing institutional controls on the Cabot iu*ea of the Site. Lastly, the plan included treating groundwater and sampling groundwater and surtace water.

In 1994. Cabot Carbon dug up and removed contaminated soil and sediment from the Cabot Carbon iu*ea of the Site. Later in 1994. Cabot CiU'bon built a groundwater interceptor trench system on the Cabot Carbon area of the Site on North Main Street and intercepts contiiminated groundwater from the shallow aquifer and discluu'ges it to the local publicly owned treatment plant. This groundwater interceptor trench has removed over 500 million gallons of groundwater since installation. In 2011. Cabot Carbon removed 116 tons of contaminated sediment from Hogtown and Springstead Creeks impacted by waste discharge from operations on the Cabot Carbon area of the Site.

In 1995. Beiizer East constructed and operated a groundwater pump iind treat system that extracted groundwater from the Surficial aquifer initially iind later was upgraded to exiract contaminated groundwater from the l^pper Eloridian aquifer as well. Tliis groundwater pump- and-treat system has pumped and treated 392 million gallons of water from the Surficial and l^pper Eloridian aquifer. .A portion of the treated groundwater is used to iirigate the Site vegetation. Beiizer East installed and sampled two sentinel wells between the Koppers area of the Site and the Gainesville Regional Ihility (GRl^ Muiphee Wellfield. GRl^ sampling of groundwater at the Muiphee Wellfield has shown no detections of Site contaminants there at the Muiphee Wellfield.


In 2011. PRPs finished tearing down and removing all fonner tacility structures from the Cabot Carbon iu*ea of the Site. Beazer East also completed stonn water system improvements, added crushed rock to roads at the Site and planted grass over a large portion of the Site to control dust. In Februaiy 2011. the EP.A issued the Record of Decision Summaiy of Remedial .Alternative Selection, a second cleiinup phin for the Site. This plan finalized cleiinup activities for both the Koppers and Cabot Carbon areas of the Site and revised requirements in the 1990 ROD.

In May 2011. Beazer East submitted a work plan for cann ing out a full-scale in-place geochemical stabilization (ISGS) demonstration in the fonner Process .Ai*ea in the l^pper Haulhom aquifer. ISGS injections took place in MiU'ch 2014 with promising initial results. The EP.A anticipates submittal of a solidification stabilization pilot test work plan in the neiu* future to address source area contamination in the fonner North Lagoon and Drip Track source areas. Cabot Carbon submitted a work plan for outlining possible Site-related contaminants in groundwater of the Haulhom Group in early 2011. Tlie EP.A approved this work plan. Cabot implemented the plan in September 2011. Results showed contamination of Haulhom Group groundwater with more Site-related contaminants than allowed in the groundwater cleanup standards included in the 2011 ROD. Cabot is required to remediate the contaminated groundwater using in-place treatment technology.

Tlie EP.A iind Beazer East entered into an agreement in July 2013. requiring Beazer East to design and implement the selected remedy at the Koppers portion of the Site. Tliese activities have already begun at both the Koppers and Cabot CiU'bon portions of the Site. Beazer East completed the otfsite soils remediation in November 2014. 103 residential structures and seven commercial buildings, four vacant lots, iind the Genesis Preparatoiy School had contaminated soils removed and replaced with clean soils, as well as new landscaping installed. Tlie treatment of contiiminated groundwater using in-situ geochemical stabilization (ISGS) injections has begun at the Koppers Process .Ai*ea in both the Surficial and Hawthorn aquifers.

Tlie EP.A is basing the groundwater cleanup on EP.A FDEP drinking water Maximum Contaminant Levels (MCLs) iind has selected detault Florida risk-based coirective action soil cleanup levels and detault EP.A FDEP sediment levels adjusted for background for sediment cleanups.

Tlie treatment of contaminated groundwater using in-situ geochemical stabilization (ISGS) injections was completed in September 2015 in the Koppers Process .Ai*ea in both the Surficial and Haulhom aquifers. ISGS injections are scheduled to begin in the Koppers South Lagoon .Ai*ea in 2017 in the same aquifers. Vertical hairier wall installation is also scheduled to tiike place in 2017 as well as sediment removal from a drainage ditch leading to Springstead Creek.

EP.A completed the last Five-Year Review in MiU'ch 2016. EP.A plans to complete the nexi Five- Year Review in 2021.


2.2 Site Description/Location

Tlie 136-acre Site is located at Main Street & 23'^^' Avenue. Gainesville. Florida 32601. Gainesville is located within Alachua County. Tlie Site is about one mile east of l^S Highway 441. Tlie Koppers area covers 86 acres on the western side of the Site, and the Cabot Carbon area covers 50 acres on the eastern side of the Site.

Specific by-products detected on the Koppers portion of the Site include creosote, pentachloiphenol. and copper-chromium-arsenic (CC.A). Two wastewater ponds, a former cooling pond process area, and a drip track area were identified in this portion of the Site. Investigations perfonned at Koppers in the 1980s revealed soil and groundwater contamination on-Site.

Single tamily and multiple tamily residential properties are located to the immediate west of the Site and commercial lacilities border the southern and eastern portions of the Site along Northwest 23rd .Avenue and North Main Street. The Stephen Foster Neighborhood is the closest neighborhood to the Site.

Businesses and apartments border the Site to the north and south. Ihideveloped land borders the Site to the east iind single-tamily homes border the Site to the west. The City of Gainesville's Public Works Compound and Springstead Creek are located northwest of the Site. .A shopping mall. Ciu* dealerships and several other businesses also cuirently operate on the Cabot Carbon portion of the Site.

Tlie Suwiinnee River Water Management District listed the Site and nearby suirounding area as a groundwater delineation area. Tins means all wells put in the area need the District's approval. Tlie Site is also located within the .Alachua County Murphee Wellfield Protection Zone, which restricts installation of groundwater wells. .A portion of the Cabot Koppers Site is cuirently in commercial reuse.

Groundwater monitoring by Cabot Carbon iind Beazer East is on-going to address the required remedial design and remedial action in the Surficial. Haulhom. and l^pper Floridian aquifers. Tlie EPA negotiated legal agreements with the Site's PRPs to investigate iind clean up the Site. Tlie PRPs continue to fund Site cleanup, monitoring and oversight activities.

Tlie parties responsible for Site contiimination performed the Site cleanup. Cleanup activities included removal and treatment of contaminated soil, groundwater treatment and removal of contiiminated soil from homes. Tlie EP.A. state and local government, responsible piU'ties and local developers are working together to successfully clean up the Site. This collaboration also led to beneficial reuse of the Site.

Tlie EP.A. FDEP iind PRPs continue to protect people and the environment from Site contamination by treating groundwater, testing soil, conducting cleanup activities and undertaking Five-Year Reviews.

Tlie EP.A is engaging the impacted community to build relationships and to assess concerns of stakeholders. Inlbnnation from the community and stakeholders is required for the development of the Community Involvement Plan (CIP). Tlie EP.A community involvement personnel will establish a timeline for future interactions and coordinate with stakeholders to help build their capacity.

Tlie EP.A has directed the responsible parties Beiizer East (Koppers) and Cabot Carbon to treat contaminated soils, sediments, groundwater, and surtace water through the 1990 Record of Decision (ROD) iind through an updated ROD in 2011. The Site is cuirently undergoing remedial design and remedial action.

3.2 History of C'ommunitj Involvement

Tlie EPA has led many community involvement activities to engage the community input. The activities also ensure the public remains informed about Site actions tlu'oughout the cleanup process. Outreach etToils have included public notices, community interviews and inlbnnation meetings. (Ongoing) The EP.A initially awarded a Technical .Assistiince Grant (T.AG) to the Protect Gainesville's Citizens (PGC). Inc. organization to help the community participate in the Site decision-making process. The group worked with advisors to inteipret iind help the community understand teclmical inlbnnation about the Site. PGC. Inc. chose not to pursue iin additional T.AG in 2015. EP.A is now working with the Stephen Poster Neighborhood .Association as a Community .Advisoiy Group (C.AG) and awarded a contract to the Water and .Air Research to conduct community involvement, technical evaluations, and outreach elTorts on behalf of the community

Tlie City of Gainesville (COG). Gainesville Regional Ihilities (GRl^- .Alachua County Environmental Protection Depiulment (.ACEPD). iind Water and .Air Research provide teclmical representatives to participate in the Local Intergovernmental Team with EP.A and PDEP in evaluating and making recommendations on the Site remedial design mid action work phms. EP.A conducts monthly conlerence calls with teclmical representatives of GRlk .ACEPD. COG. PDEP. and the Site responsible piU'ties Beazer East imd Cabot Carbon. Below is a list of some of the outreach activities that have been conducted to date:

October 1988: EP.A issued a tact sheet that provided a brief background imd histoiy of the Site and described the Remedial Investigation feasibility Study process.MiU'ch 1989: EP.A issued a Conmuinity Relations Plan..August 1990: EP.A sent out a fact sheet to the community announcing the Proposed Plan. Tlie tact sheet explained the puipose of the Proposed Phm and it aimounced the .August 14"' public meeting to discuss the Proposed Plan..April 1994: EP.A issued a tact sheet announcing the completion of the Site Remedial Design.MiU'ch 2001: EP.A completed the first PVR which included notifying the community through a newspaper public notice and community interviews..April 2001: EP.A issued a Proposed Plan tact sheet announcing a ROD .Amendment. It provided an opportunity for the public to attend a public meeting and to comment on the proposed mnendment..April 2006: EP.A completed the Second PVR which included notifying the community through a newspaper public notice and community interviews.June 2010: EP.A issued a tact sheet which provided im update on the cleanup of the Site (See attached).September 2010: EP.A issued a Proposed Phm Pollow-up Prefeired Remedy tact sheet. It provided a brief Site summaiy. addressed specific components of the prefeired remedy, discussed community concerns related to remedial activities and announced an upcoming .Availability Session that was held October 2010 (See attached).October 2010: Koppers Community Involvement Phm.MiU'ch 2011: EP.A completed the Third PVR which included notifying the community through a newspaper public notice and community interviews.


• May 2011: EPA revised the Community Involvement Phin.• July 2015: EPA contractors perfonned community interviews to get their concerns and

answer their questions about the Site.• MiU'ch 2016: EPA completed the Eouilh PVR which included notifying the community

through a newspaper public notice and community interviews.• Januaiy 2017: EPA representatives attended the Stephen Poster Neighborhood Association

public meeting and provided an update of remediation of the Site iind an overview of the College Ihiderserved Community Partnership Progmm (CITP). See Appendix J for a description of Cl^PP.

Tlie community has played an active role in presenting their concerns regarding the remedial action to the public. The local media has played an integral piu1 in educating the community on the Site-related activities.

3.3 Key C'ommunity C'oncerns

In 2015. six .Alachua County residents were interviewed to document any perceived problems or successes with the remedies that have and continue to be implemented at the Site. Tlie results of these interviews are summarized below.

1. Most residents expressed that the Site's remedy in effect was elTicient.

2. Continue to ensure that residents receive more EP.A based infonnation such as monthly phone calls, lace-to-face contact, and PRP-based infonnation. as most residents are still requesting iiilbnnation from the EP.A.

3. Continue to ensure that Koppers and Cabot Carbon have a similar cleiinup process, as residents expressed that the Cabot Carbon cleanup process was slower, and residents expressed that they were not comfortable with the reuse of Cabot Carbon.

4. Ensure that odors emanating from the lift station cease as an industrial hygiene worker was exposed to the odor. .An ambient air quality assessment was perfonned and indicated that the levels were below Occupational Safety and Health .Administration (OSH.A) standards as well as the EP.A ambient air quality stiindards.

5. Continue to allow residents to express interest in participating in strategies to help with redevelopment options for Koppers.

6. Continue to keep residents aware of any remediation during cleanup on the Site.

7. Ensure that the EP.A continues to always include city and county olTicials in discussion and review of documents, and continue to recommend members of the community to become more involved with a focus on the Superfund process.


8. Ensure that the percentage of human health and ecological impacts of contamination caused by the Site, regarding dioxins and PAH compounds, remain monitored.

9. Ensure that attention is placed on preventing downward migration of Non Aqueous Phase Liquid (NAPE) and or dissolve phase contamination, since there's a possibility of it leaking into Eloridiiin aquifer.

3.4 Response to C'ommunity C'oncerns

Tlie EP.A is adding a bairierto suiround the Koppers area. Tlie vertical bairier wall will contain the four fonner source areas at the fonner Koppers Site, and is being done with a planned construction date of mid-2018. In-Situ Geochemical Stabilization (ISGS) injections will occur in the fonner South Lagoon during the 2018 timeframe.

3.5 Summary of C'ommunication Needs

Based on the community interviews, most residents would like to receive more infonnation directly from the EP.A via phone calls, tace-to tace contact, and PRP-based inlbnnation.


Section 4.0EPA’s C'ommunitj Involvement Program

Tlie overall goal of the EPA's community involvement program is to promote two-way communication between citizens and the EPA and to provide opportunities for meaningful iind active involvement by the community in the cleanup process. The EPA will implement the community involvement activities described below. The following plan is based on the results of the community interviews described earlier. The plan addresses each issue that was identified as important to the community.

4.1 The Plan

Issue 1: Keeping the public infonned and up to date.

Acti\ity lA: Designate an EPA Conuiiuiiity In\ohenient Coordinator (CIC).

• Objective: To provide a primaiy liaison between the community iind the EP.A. iind to ensure prompt, accurate, and consistent responses and information dissemination about the Site. In those instances, where the EP.A's CIC may be unable to provide adequate infonnation (such as on technical issues), inquiries will be directed to the appropriate EP.A contact.

• Method: The EP.A will designate an EP.A CIC to handle Site inquiries and serve as a point of contact for community members. Tlie CIC is appointed by the EP.A Region 4. .Abena .Ajiinaku is the EP.A CIC assigned to the Cabot Carbon Koppers Site. She will work closely with Scott Miller, the EP.A's Remedial Project Manager for the Site.

• Timing: Tlie CIC. .Abena .Ajanaku. became actively involved in 2016.

.Acti\ity IB: Prepare and distribute Site fact sheets and tecluiical suininaries.

• Objective: To provide citizens with cuirent. accurate, easy-to-read, easy-to-understand infonnation about the Site.

• Method: Pact sheets will be mailed to all parties on the Site mailing list. In addition, copies will be available at the inlbnnation repositories (See .Appendix H) and other locations as identified by the community.

• Timing: Tlie EP.A will prepare and distribute fact sheets on an as needed basis.

Cabot Carbon Koppers Supeifund Site Community Involvement Plan Page 2() November 20!

Acti\ ity 1C: Pro\ icle a toll-free ‘‘800 number'’' for the coniniuiiity to contact EPA.

• Objective: To enable citizens to obtain the latest information available whenever they want, rather thiin having to wait for a meeting or a tact sheet, and without incuiring any cost.

• Method: The EPA will activate the 800 number and publish the number periodically in the local papers iind in all tact sheets.

• Timing: Tlie toll free number is cuirently operational (1-877-718-3752).

.\cti\ity ID: Maintain a mailing list for the Site.

Appendix JThe College Underserved Community Partnership Program

The College Underserved Community Partnership Program (CUPP) was started at EPA to help address community concerns that fall outside the scope of Superfund cleanup efforts but are very real barriers to the sustained health and growth of surrounding neighborhoods.

CUPP provides assistance to these communities to help improve their economic viability, health, and overall quality of life. CUPP enlists colleges and universities to provide vital technical support through student internships and capstone projects. Communities benefit from the schools’ investment of technical assistance and innovative approaches; students gain practical experience in their areas of academic study and the opportunity to make meaningful contributions to nearby communities.

CUPP projects have addressed issues ranging from economic development to Site planning to improve community health. CUPP helps build relationships that endure long after the initial projects are finished, contributing to stable and sustainable community growth.CUPP works with communities on self-identified issues by meeting and listening to elected officials’ and residents’ concerns. Together they develop a list of possible projects and prioritize them according to community needs. CUPP identifies nearby academic institutions with appropriate areas of study who are willing to help. The schools assign academic leads who oversee the projects and guide the students; CUPP facilitates meetings and, if needed, engages other federal agencies and non-govemmental organizations to support the project.CUPP has over 70 colleges currently committed to the program and is actively adding new schools and partners. There is no cost to the community to participate in CUPP.To engage CUPP, contact your Community Involvement Coordinator or Remedial Project Manager.

Appendix L Glossary

Adniiiiistrati\ e Order on Consent (Adiiiiiiistr’ati\ e Order):A legal agreement between the Ihhted States Environmental Protection Agency (EPA) and potentially responsible piulies (PRPs) whereby PRPs agree to conduct or pay the cost of a Site investigation and or cleanup. In contrast to a consent decree, an administrative order by consent does not need to be approved by a judge.

.Adniiiiistnitive ReconI File:.A file that is maintained for the public iind contains infonnation used to nuike a decision about a Site under the Comprehensive Environmental Response. Compensation, iind Liability .Act (CERCL.A). Tlie file is available for public review, and a copy is usually placed in the same location as the Site information repositoiy. .A duplicate file is held at a central location, such as the EP.A Regional otTice.

.Agency for Toxic Substances and Disease Registiy (.ATSDR):Superfund created .ATSDR within the federal Public Health Service to work with other government agencies to initiate and implement a variety of health-related responsibilities. .ATSDR develops toxicological profiles, prepiu'es Site-specific health assessments, establishes fonnal registries of persons exposed to hazardous substances, develops and disseminates health education inlbnnation. establishes and maintains literature inventories on hazardous substances, helps prepare health and safety programs for workers at Superfund Sites and workers responding to emergency releases, and provides health-related support in public health emergencies.

.Availability Session:.An "open house" event hosted by EP.A to meet informally with citizens about Site activities.

Cleanup:.Actions taken to deal with a release or tlu'eatened release of haziu'dous substances that could atTect public health or the environment. The tenn is often used broadly to describe viu'ious response actions or phases of remedial responses, such as the Remedial Investigation feasibility Study (RI ES).

Cleanup Remedy:.A prescribed teclmical approach to reducing the concentrations of contamimints at a Site. EP.A selects a cleanup remedy from alternatives identified in the feasibility study after applying a set of balancing criteria and considering public comments.

Conipreliensi\e En\iroiunental Response, Coinpensation, and Liability .Act (CERCL.A):federal Law. commonly known as Superfund, passed in 1980 and modified in 1986 by the Superfund .Amendments and Reauthorization .Act (S.AR.A)to investigate and cleanup abandoned or uncontrolled hazardous waste Sites (CERCL.A is commonly known as Superfund, because the .Act created a special tax that goes into a Trust fund). EP.A either


Koppers Superfund Site pays for the Site cleanup when the responsible parties cannot be located or are unwilling or unable to perfonn the remedial actions, or takes legal action to force responsible parties to clean up the Site or reimburse EPA for the cost of the cleanup.

Coniinuiiity Iii\ oheiiieiit Plan (CIP):Tlie goals of the CIP are to infonn the public of planned and ongoing Site activities: maintain open communication about Site remediation: ensure concerns are acknowledged and addressed provide interested parties with useful infonnation: provide citizens with opportunities to comment on and be involved in technical decisions: iind encourage and assist local citizens in providing input to agency decisions that will have long-tenn etTects on their community.

Feasibility Study (FS):Tlie second part of a two-part study called a remedial investigation feasibility study. The feasibility study involves identifying and evaluating the most appropriate technical approaches to addressing contamination problems at a Site. .Alternatives are evaluated for their etTectiveness in protecting humiin health and the environment.

Florida Depai*tiiieiit of Eii\ ironniental Protection (FDEP):.An agency in Florida's government cluu'ged with most functions relating to environmental quality in the state.

Groundwater:Water found underground that fills pores between materials such as mud. soil, or gravel. In aquifers, groundwater often occurs in qualities where it can be used for drinking water, iirigation. iind other puiposes.

Hazard Ranking System (HRS):.A numerical screening system used by EP.A to evaluate the relative potential risks to public health iind the environment from releases or threatened releases of hazardous substiinces from contaminated Sites. Data from prelimimuy Site investigations is used to develop a Site score from 0 to 100 indicating the potential for substances released in groundwater, air. surftice water, or soil to aftect people on or near the Site. Tlie HRS ranking is the principal tact or used to detennine if a Site qualifies for the National Priorities List.

Health Consultation:.A review of available data by the .ATSDR at EP.A's request to determine if existing levels of contaminants and conditions at a Site iu*e creating a public health luizard that requires immediate action.

Cabot Carbon Koppers Supeifund Site Community Involvement Plan Page 5() November 20!

Inforniation Repositon :Tlie inforniation repositon is usually located in a public building that is convenient for local residents, such as a public school, city hall, or libraiy . and contains cuirent inforniation. teclmical reports, reference documents, and other inlbmiation regarding a Superfund Site. As the Site proceeds tlu'ough the remedial process, the file at the inforniation repositoiy is contractually updated.

National Priorities List (NPL):.A list generated by EP.A depicting the uncontrolled or abandoned hazardous waste Sites that are priorities for long-temi remedial investigation (RI) iind response. The list is based primarily on the score a Site receives on the Hazard Ranking System. .A nonfederal site must be on the NPL to receive money from the Trust Fund for Remedial .Action. Federal properties listed on the NPL do not receive money from the Trust Fund, but EP.A takes a more fomial role in the cleiuiup process. EP.A is required to update the NPL at least once

a year.

Potentially Responsible Party (PRP):.An individual, company, or group of companies that may have contributed to the hiizardous conditions at a Site. Tliese parties may be held liable for costs of the remedial activities by EP.A through CERCL.A laws.

Preliininaiy .Assessnient:Tlie process of collecting and reviewing available inlbmiation about a known or suspected hiizardous wa.ste Site or release status.

Proposed Plan:.A public participation requirement of CERCL.A in which EP.A iind or the PRP sumniiu'ize for the public the prefeired cleanup strategy, rationale for the preference, and alternatives presented in the detailed analysis of the RI FS. The proposed plan may be prepared as a tact sheet or a separate document. In either case, it must actively solicit public review iind comment on all alternatives under consideration.

Public Coininent Period:Tlie time in which the public can review and comment on various documents. .A 30-day minimum comment period is held to allow the community to review iind comment on the document.
