______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page i Section 1.0 Overview of the Community Involvement Plan
The United States Environmental Protection Agency (EPA or the Agency) developed this Community Involvement Plan (CIP) to inform and involve the community in a two-way discussion about the Helena Chemical Company (Tampa Plant) Superfund Site (the Site). This CIP has been developed by the EPA’s Superfund* Program pursuant to 40 CFR §400.430, 40 CFR §400.35, and 40 CFR §805(c). It provides information about community concerns and presents a plan that is intended to enhance communication between local residents and the EPA as the investigation and cleanup at the Site progresses.
The objective of the EPA’s Superfund Community Involvement Program is to involve the public in a wide variety of site-related decisions, including site analysis and characterization, alternatives analysis, and selection of the remedy. The EPA recognizes the importance of actively soliciting comments and information from the community during the decision-making process. Public input can be useful in two ways:
• Communities are able to provide valuable information on local history, citizen involvement, and site conditions. • Communities that express concerns assist the EPA in recognizing the unique characteristics of each site community and in developing a response that more effectively addresses specific community needs.
This CIP consists of the following sections:
• Site History, Description, Inspections and Cleanup Activities. • Community Background including a profile of the City of Tampa and Hillsborough County, Key Community Concerns, Response to Community Concerns and a Summary of Community Needs. • EPA’s Community Involvement Program, Long Term Monitoring, Partnership Development, Enhanced Communication, and a Time Frame Summary for Community Involvement Activities.
The Appendices to this CIP contain the following information:
• Contact information for EPA Region 4, Local Officials, State Officials, Federal Elected Officials, Environmental and Active Citizens Groups, Potentially Responsible Parties (PRPs), and Media Contacts. • Location information for meetings and the Site’s information repository. • A Glossary, Acronym List, and References.
The EPA Region 4 has the lead responsibility for managing the investigation, selecting the cleanup alternatives, providing technical information, and ensuring community involvement in the work at the Site.
*Words appearing in boldface type are defined in Appendix J, Glossary.
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 1 Section 2.0 Capsule Site Description
2.1 Site History
In 1929, Flag Sulfur Company built a chemical plant for the production of wettable and dusting sulfur, as well as for the formulation of pesticides, herbicides, fungicides, and fertilizers. Helena Chemical Company (HCC) purchased the plant in 1967 and continues to operate the plant today. HCC formulated wettable pesticides in the East Warehouse building using aboveground mixing vessels using solvents (primarily xylene). HCC’s pesticide/xylene waste was diluted with process water and stormwater, treated with caustic soda, and discharged to the on-site stormwater retention pond. Sludge associated with the treatment system was periodically removed for off- site disposal at the Chemical Waste Management, Inc. facility in Emelle, Alabama. A 3,500- gallon aboveground xylene storage tank was located in a bermed area east of the East Warehouse building, which was vandalized in 1977, causing a release of xylene to the soil and groundwater.
HCC also formulated and packaged finished dry products for resale in the West Warehouse building just south of the loading dock. HCC’s sulfur processing operations consisted of transporting molten sulfur to the Site and unloading the sulfur in the former sulfur pit area located south of the paved courtyard between the West and East Warehouse buildings. The sulfur was contained in berms for about 48 hours until it solidified. Operators then used heavy equipment to break the sulfur into pieces for processing using the grinding equipment.
HCC stopped processing sulfur products in 1976 and discontinued the formulation of dry fertilizers at the facility in 1980. In 1981, HCC moved its pesticide, herbicide, and fungicide formulation operations to Georgia, and began formulation of insecticidal petroleum oil and liquid fertilizers at the Site. The Site was also used to store numerous agricultural products a warehouse prior to distribution.
EPA’s investigation of the Site from 1988 to 1990 found pesticide contamination in on-site soils, sediments, and in the surficial aquifer. Based on the potential for human exposure via ingestion of contaminated groundwater, the EPA proposed the Site to the National Priorities List (NPL) of Hazardous Waste Sites in February 1992 and finalized the listing in October 1992. An NPL listing authorizes the EPA to conduct environmental cleanup in well-defined steps in accordance with the National Contingency Plan and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund. The Superfund program has the authority to force PRPs to perform the cleanup or reimburse the Agency for the Superfund-led cleanup work.
In September 1992, the EPA issued an Administrative Order by Consent to HCC to complete a Remedial Investigation and Feasibility Study (RI/FS) at the Site. Completion of a RI/FS is the first step in the Superfund process that identifies the nature and extent of contamination and identifies potential strategies or remedial actions that could clean up site-related contamination. In addition to the RI/FS, the Florida Department of Health and Rehabilitative Services (FHRS), in cooperation with the Agency for Toxic Substances and Disease Registry, prepared a public
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 2 health assessment for the Site in September 1993. FHRS indicated that exposure of on-site workers to contaminated soil, sediment and groundwater may pose health concerns.
Superfund recognizes the value of soliciting the community’s insight into selecting a preferred remedial action. Therefore, prior to issuing a Record of Decision (ROD) for this Site, the EPA summarized proposed remedial actions and associated costs into a Proposed Plan and invited the community’s participation in selecting a preferred remedial action. Following consideration of all public comments, the EPA documented the preferred alternative in a ROD issued for the Site on May 7, 1996. The ROD contains a Responsiveness Summary showing the responses to all comments collected during the 30-day public comment period. The RI/FS, Proposed Plan, and ROD are all sequential steps in the Superfund process.
On December 10, 1996, the EPA issued a Unilateral Administrative Order for Remedial Design and Remedial Action (UAO) to HCC to perform the remedial work at the Site. HCC is continuing to perform the work under the UAO.
2.2 Site Description/Location
The 8-acre Site is an operating agricultural products distribution facility located at 2405 North 71st Street in Orient Park, a commercial and industrial area in the City of Tampa, Hillsborough County, Florida. The facility’s central area is covered with concrete. A chain-link fence surrounds the entire Site. Primary Site features include the West Warehouse, the East Warehouse, holding tanks in the former sulfur pit area, and an unlined runoff retention pond located in the southeast comer of the Site, downgradient of the former xylene tank area.
The Site consists of four land parcels. The largest of these parcels (6.5 acres) includes HCC’s offices, warehouses and distribution centers, as well as associated paved parking areas. This parcel is zoned for heavy industrial land use. Three smaller parcels form the Helena Woods area. They are covered by low grassy vegetation and oak trees and also contain several groundwater monitoring wells for the Alaric Area Groundwater Plume Superfund Site (Alaric Site), located immediately to the north and west of the Site’s main operating facility. The three smaller parcels are also zoned for heavy industrial uses.
Surrounding land uses include various light and heavy industrial land uses, as well as commercial uses. Small areas of single-family residences are located several blocks to the north and to the west of the Site. Along the southern border of the Site is a CSX-operated rail line. The Site is situated between two other Superfund sites, the Alaric Site, and the Stauffer Chemical Company (SCC) Superfund Site to the southeast of the Site, on the southern side of the CSX railroad tracks.
Site topography is relatively flat, with the land surface generally sloping to the south and southeast toward the railroad and the SCC facility along the eastern bank of the Tampa Bypass Canal. The Site is about 0.5 miles west of Six Mile Creek and the Tampa Bypass Canal. During periods of intense and extended rainfall, the Site is subject to flooding. Surface water at the Site consists entirely of stormwater runoff. Stormwater runoff from the central portion of the Site channels into concrete drainage swales and flows into a retention pond in the southeastern comer ______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 3 of the Site. A spillway at the retention pond allows overflow to drain into a drainage ditch parallel to the CSX railroad tracks. The retention pond is part of the runoff control system at the Site and does not constitute a significant ecological habitat. On the western and northern boundaries of the Site, stormwater flows to the southwest into a low-lying area and then flows to the north via a ditch/culvert system along North 71st Street. Surface water flow along the eastern boundary continues south along a ditch parallel to Orient Road to an unnamed stream and eventually to the Tampa Bypass Canal.
The Site is situated above three groundwater aquifer zones: a shallow surficial aquifer that extends 11 feet below the ground surface (bgs), an intermediate aquifer system (IAS), and the Floridan aquifer. The bottom portions of the surficial unit are saturated year-round; the water table fluctuates with precipitation, with seasonal high-water tables rising to within one foot bgs. The IAS separates the surficial aquifer from the Floridan aquifer, which is encountered at 80 feet bgs. Groundwater flow at the Site is in a radial pattern to the northeast, east, southeast, south, and southwest. Buildings on-site and throughout the area impacted by Site-related groundwater contamination are connected to municipal water supply lines. The groundwater wells impacted by contamination from the Site are not used for potable water supplies.
The RI/FS documented extensive surface soil and sediment contamination, including pesticides, semi-volatile organic compounds (SVOCs) and volatile organic compounds (VOCs) related to former operations by HCC and its predecessors. The investigations also documented contamination of groundwater with pesticides, polycyclic aromatic hydrocarbons (PAHs), phenols, and VOCs.

______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 5 2.3 Site Inspections and Cleanup Activities
In 1984, the Florida Department of Environmental Protection (FDEP) inspected the Site and determined that quarterly monitoring of the surficial aquifer was required. From 1988 to 1990, the EPA investigated the Site at the request of the FDEP, and found pesticide contamination in on-site soils, sediments and the surficial aquifer. The EPA issued the Site’s ROD on May 7, 1996, selecting the remedy to address the contaminated soils, sediments, and groundwater. The ROD can be found in the local information repository at the University of South Florida Library and in the EPA Regional Information Repository (see Appendix I for addresses). Remedial action objectives established in the ROD include:
• Restoration of the Site to beneficial use; • Reduction of risk to human health; • Reduction of ecological risk; and, • Protection of groundwater from continued degradation by Site contaminants.
The selected remedy for source control in soil and sediment consists of the following components:
• Implementation of institutional controls (ICs) (i.e., restrictive covenants) and engineering controls, such as fencing; • Demolition of tank farm pads east of the liquid processing building (East Warehouse) and dispose of the debris off site; • Excavation of material from the former sulfur pit and dispose of excavated materials off site; • Neutralization of soils in place if located in areas where sulfur is present but inaccessible; • Excavation of contaminated surface soils and sediments (0 to 2 feet) where concentrations exceed soil cleanup goals; • Use of on-site biological treatment for contaminated surface soil and sediment; and, • Placement of treated soil back on site.
The major components of the groundwater remedy include:
• Extraction of contaminated groundwater; • Treatment of contaminated groundwater to meet surface water discharge standards; • Discharge of treated groundwater to on-site ponds or to the Tampa Bypass Canal under a National Pollutant Discharge Elimination System permit; • Placement of controls on-site to restrict the use of groundwater beneath the Site through the filing of deed notices in order to limit exposure to contaminated groundwater until cleanup goals are met; and, • Monitoring of groundwater in the Floridan aquifer to determine if an additional groundwater action is required.
The cleanup goals established in the 1996 ROD for contaminants of concern (COCs) in groundwater and surface soil are presented in the following table. Based on Site data, sediments ______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 6 with pesticide contamination were primarily present in drainage ditches that were typically dry. Therefore, remediation of sediment in Site drainage features was managed using the surface soil cleanup goals protective of human health. The 1996 ROD also selected a contingency remedy for soil and sediment. If studies demonstrated that the selected biological treatment remedy could not achieve the performance standards listed in the ROD, low temperature thermal desorption was to be used in lieu of the biological treatment.
The cleanup levels specified in the 1996 ROD are:
COC Groundwater Surface Soil and (µg/L) Sediment (mg/kg) Aldrin 0.05 0.18 alpha-Benzene hexachloride (alpha-BHC) 0.05 0.47 beta-Benzene hexachloride (beta-BHC) 0.1 NA gamma-Benzene hexachloride (gamma-BHC) 0.2 NA Chlordane NA 2.3 Dichlorodiphenyldichloroethane (DDD) NA 12.6 Dichlorodiphenyldichloroethylene (DDE) NA 8.9 Dichlorodiphenyltrichloroethane (DDT) 0.3 8.9 Dieldrin 0.1 0.39 Endosulfan I 2 NA Endosulfan II 2 NA Heptachlor NA 0.67 Heptachlor epoxide NA 0.34 Total xylenes 10,000 NA Toxaphene NA 2.76 µg/L = micrograms per liter mg/kg = milligrams per kilogram NA = not applicable
In January 2005, the EPA issued an Explanation of Significant Differences (ESD) to modify part of the remedy described in the 1996 ROD. The purpose of the ESD was to modify the xylene cleanup goal for groundwater from 20 micrograms per liter (µg/L), per the Florida secondary maximum contaminant level (MCL), to 10,000 µg/L, per the state and federal primary MCL. The ESD also called for continued monitoring of the effectiveness of the xylene treatment and for evaluation of further remedial actions should the presence of xylene, a solvent, mobilize residual soil pesticide contaminants into groundwater.
Status of Implementation
Soil and Sediment Source Control
Soil treatment pilot studies were completed in 1999 and determined that treatment of the soils in- situ (in place), did not have an effect on COC degradation. Therefore, in February 2000, the EPA approved a change from on-site to off-site treatment and disposal of contaminated soils and sediments. ______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 7
In 2000, HCC excavated 7,700 tons of pesticide-contaminated soil from a retention pond, including the xylene source area, and additional pesticide-contaminated soil and sediment from the drainage ditch area along the CSX railway right-of-way just south of the Site. Soils were transported off site to the Chemical Waste Management, Inc. (CWM) facility in Carlyss, Louisiana, for bioremediation and disposal. The excavation areas were lined with a geotextile fabric prior to backfilling the areas with clean materials, and then seeded with grass where appropriate.
HCC began remedial work at the former sulfur pit area in 2004. The work included dismantling a metal building covering much of the area and transporting it to an off-site recycling facility. In addition, 1,800 tons of sulfur-contaminated soil and concrete was excavated from the elevated loading dock area, as well as from the west side of the tank farm, for off-site treatment and disposal. In 2005, an additional 1,100 tons of sulfur-contaminated soils and concrete were excavated from the northern tank farm and former warehouse boundaries. Soils and crystallized (formerly molten) sulfur were removed and shipped to the CWM facility for disposal. HCC then placed bulk agricultural lime at the base of each excavated grid, which was incorporated into about two feet of the soil remaining at the excavation base (roughly 4 to 6 feet bgs). Following the mixing of the lime, HCC covered excavated areas with a geotextile membrane to mark the extent of excavation and then backfilled to the pre-existing grade with certified clean fill.
The 2005 ESD included post-treatment monitoring of the xylene area to assess if xylene in groundwater could mobilize residual pesticides in soils. In May 2005, HCC confirmed that elevated levels of xylenes in soils were acting as an ongoing source of groundwater contamination. In June 2008, the EPA and FDEP met and determined that monitored natural attenuation was not effectively addressing the migration of xylenes and BHCs in the groundwater and suggested further investigation of additional sources. In September 2008, the EPA and FDEP determined that in-situ remediation should be considered for residual soil and groundwater contamination.
Groundwater
The pump-and-treat groundwater remedy described in the 1996 ROD has not been implemented due to discovery of groundwater contamination and investigations at the adjacent Alaric Site. HCC did not implement the groundwater remedy due to concerns that it would potentially cause further contamination of the aquifer systems. In June 2009, HCC prepared a work plan to conduct a pilot test for in-situ remediation and to start interim monitoring of groundwater. The EPA approved the work plan in August 2009. In September 2009, HCC completed injections of zero-valent iron and a hydrogen-release compound. Sampling in January and March 2010 indicated a decrease in the concentrations of some of the COCs. In February 2011, HCC, the EPA, and FDEP met and determined that the pilot study results were inconclusive and recommended collection of one additional year of data to determine if the pilot study was successful. In November 2012, a meeting was held with the HHC, the EPA and FDEP to discuss the results of an August 2012 Pilot Test Assessment Report. The EPA and FDEP recommended performing additional studies at the Site to improve treatment performance in low pH sulfur- and BHC-contaminated area. In July 2014, HCC submitted a work plan detailing a design to ______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 8 neutralize the pH of the low pH sulfur and BHC areas. In January 2015, HCC prepared a Remedial Design Report. The EPA and FDEP approved the Remedial Design Report in February 2015, but the remedial action has not yet been completed.
A Site Inspection also took place in February 2015. Participants of the inspection met at the Site to discuss the Site’s remedial components and current status, including plans to neutralize the pH in groundwater in the former sulfur pit area as part of revising the groundwater remedy. The facility was an active operational pesticide packaging and distribution center at the time of this inspection.
Institutional Control Review
Fencing and deed restrictions are ICs included in the selected remedy in the 1996 ROD. The Third Five-Year Review (FYR), completed in March 2016, found that the Site was fenced and locked and that visitors must enter through an office. No deed restrictions were in place at the time of the Third FYR.
Because HCC remains in control of the property and plans to remain in control over the long term, EPA, FDEP, and HCC have agreed over the short term to defer implementation of ICs, allowing HCC to restrict property use via internal Site development plans. Once the final remedy is implemented at the Site, ICs in the form of deed restrictions will be prepared in accordance with EPA, FDEP, and HCC discussions in 2011; the restrictive covenant will limit Site use to industrial land uses and prevent exposure to subsurface soil and groundwater.
A 2008 Memorandum of Agreement between the EPA and the Southwest Florida Water Management District is an IC that addresses the need to restrict the use of groundwater in the vicinity of the Site due to the presence of contamination in groundwater.
In addition, the Third FYR Report recommended the establishment of an IC to address the potential vapor intrusion pathway in any new construction located in the currently undeveloped southeast corner of the Site (Parcel Number 158756).
Five-Year Reviews
In general, FYRs are required whenever a remedial action results in hazardous substances, pollutants, or contaminants remaining on site. The EPA has determined that FYRs are appropriate for this Site to evaluate the implementation and performance of a remedy in order to determine if the remedy is or will be protective of human health and the environment. The FYR process for this Site began in 2006. The next FYR is scheduled to take place in 2021.
The Third and most recent FYR conducted in March 2016, found that the remedy is functioning as intended for sediment and for surface soil above the water table. Contaminated surface soil and sediment were excavated and shipped offsite for treatment and disposal. Excavated areas were lined with fabric and filled with clean materials. Grass seed was planted where appropriate.
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 9 The groundwater pump-and-treat remedy has not been implemented due to commingling of the Site’s groundwater contamination with the adjacent Alaric solvent plumes. Studies have been undertaken to assess possible treatments for the contaminated areas. Groundwater monitoring will continue to determine if the plumes remain stable.
The Third FYR Report recommended the implementation of a groundwater remedy and ICs as discussed above, as well as a determination of whether benzene and ethylbenzene should be identified as COCs, as the concentrations detected in groundwater exceed their MCLs. It also recommended consideration of moving the local information repository from the University of South Florida Library to a public library to improve accessibility for the public. The Third FYR Report found the remedy to date is expected to be protective as stated in the Report’s Protectiveness Statement: “[t]he Site’s remedy is expected to be protective of human health and the environment upon completion, and in the interim, exposure pathways that could result in unacceptable risks are being controlled.”
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 10 Section 3.0 Community Background
3.1 Community Profile
City of Tampa
The City of Tampa (Tampa) consists of 175 square miles and is located on Florida’s west coast. Tampa was originally incorporated on January 18, 1849. It is the third largest city in Florida.
Tampa is a full-service city with a population estimated at 393,000. All traditional city services are provided, such as police, public works, and recreation. Tampa’s economy is founded on a diverse base that includes tourism, agriculture, construction, finance, health care, government, technology, and the Port of Tampa, which is the largest port in the State of Florida.
Seven City Council members are elected by the voters within the City Limits of Tampa to serve for a term of four years. Council members for Districts #1, #2, and #3 are elected at-large (meaning city-wide), and those from Districts #4 through #7 are elected in individual districts.
Tampa is bordered by two bodies of water, Old Tampa Bay and Hillsborough Bay, which flow together to form Tampa Bay, which in turn flows into the Gulf of Mexico. The Hillsborough River flows into Hillsborough Bay, passing directly in front of downtown Tampa and supplying Tampa’s main source of fresh water. The Palm River is a smaller river flowing from just east of the city into McKay Bay, which is a smaller inlet, sited at the northeast end of Hillsborough Bay. Tampa’s geography is marked by the Interbay Peninsula, which divides Hillsborough Bay (the eastern) from Old Tampa Bay (the western).
Hillsborough County
Hillsborough County is a county located in the west central portion of Florida. Hillsborough has a total area of 1,266 square miles and has a population of approximately 1.47 million. It is the fourth most populous county in Florida. Hillsborough County’s county seat and largest city is Tampa. There are 158 miles of shoreline in Hillsborough County. The majority of the land in Hillsborough County is urban.
On January 25, 1834, the U.S. Legislative Council for the Territory of Florida approved an act organizing Hillsborough as Florida’s 19th county. In 1845, Florida was granted statehood. At that time, Hillsborough County included what is now Pinellas, Polk, Manatee, Sarasota, Charlotte, DeSoto, Hardee, and Highlands Counties, most of Glades County, and part of Lee County.
Hillsborough County voters approved a home rule charter for the county in 1983. The responsibilities of the executive branch are performed by the County Administrator and those of the legislative branch by the County Commission. There are seven members of the County Commission; four are from single-member districts, and three are elected countywide.
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 11 Demographics
Demographic information provided through EPA’s Environmental Justice Screening and Mapping Tool (EJ Screen) was used to obtain pertinent demographic information for the area within a one-mile radius of the Site. The EJ Screen, shown below in Figure 2, combines the percentage of low-income populations into a color-coded graphic. This study area, which is shown in the circular buffer area, is composed of 3.14 miles with an approximate population of 3,447 individuals. The demographic index (or measure of where an area sits on the spectrum of development) for the study area is 63%.
When per capita income in a household is less than or equal to twice the federal poverty level, the household is considered to be a low-income household. Fifty-eight percent of the population of the study area is considered low income. The U.S. Census Bureau American Community Survey indicates that the per capita income in this area is $14,448. In comparison, 36% of the population of Florida is low income and 33% of the population of the United States is low income.
Data for the EJ Screen indicate that 67% of the population is identified as minority. When compared to minority populations in the State of Florida and the nation, 45% of Florida is comprised of minorities and 39% of the United States is comprised of minorities. The U.S. Census Bureau American Community Survey indicates that 47% of the population is Caucasian, 34% is Black or African American, and 16% is identified as some other race. In addition, 33% of the population is reported as Hispanic.
Thirty percent of the population within the study area aged 25 and older lacks a high school diploma, while 36% have a high school diploma as their highest educational attainment. Twenty- eight percent have some college education, and 6% have a bachelor’s degree or more.

______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 13 3.2 History of Community Involvement
Community engagement and public outreach are integral to the EPA’s Superfund process and to making remedial decisions at the Site. A Fact Sheet for the Site was first distributed to the community in September 1993. Since that time, a Community Relations Plan was further developed and implemented for the Site. An information repository was established in July 1995 at the Tampa Campus Library of the University of South Florida, located at 4202 East Fowler Avenue, Tampa, Florida.
The RI/FS Reports, the Baseline Risk Assessment Report, and Proposed Plan were released to the public in July 1995. These documents are incorporated in the Administrative Record for the Site. A copy of the Administrative Record, upon which the remedy is based, is located in the information repositories. In addition, the Administrative Record and the Site (project) files are available for review at the EPA Region 4 offices in Atlanta, Georgia. Notices of availability of these documents were published in the Tampa Tribune on July 20, 23, 26, and 27, 1995.
Before issuing the ROD, on July 27, 1995, the EPA presented its preferred remedy for the Site to the community during a public meeting held at the Kenley Park Recreation Center, 1301 North 66th Street, Tampa, Florida. At this meeting, representatives of the EPA answered questions about sampling at the Site, the remedial alternatives under consideration, and the preferred remedy. A transcript of the meeting was prepared and is available at the information repositories. A public comment period for the ROD was held from July 20, 1995, through September 23, 1995.
The community was publicly notified of the 2005 ESD by a notice published in a local newspaper. Notice was also provided via a Fact Sheet explaining the ESD, which was mailed to the public. Supporting information was included in the Administrative Record and was available at the Site information repositories for public review.
In January 2011 and February 2016, public notices were published in the Tampa Tribune announcing the commencement of the Second and Third FYR processes for the Site, providing contact information for EPA’s Remedial Project Manager (RPM), Galo Jackson (currently Carter Owens), and the Community Involvement Coordinator (CIC), L’Tonya Spencer-Harvey, and also invited the community’s participation.
3.3 Key Community Concerns
EPA did not receive any responses from members of the public to the notices provided for the Second and Third FYR processes.
3.4 Response to Community Concerns
Information repositories were set up to provide information to the public about the selection of remedial alternatives. One is located in the University of South Florida Library in Tampa, and the other is located in the EPA Regional Information Repository. Information has been added to
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 14 the repositories as additional investigations have been completed (e.g., the ESD in 2005). Locations of the information repositories are found in Appendix I.
Information about the Site is also available on an EPA website: https://www.epa.gov/superfund/helena-chemical, “Superfund Site: Helena Chemical Co. (Tampa Plant) Tampa, FL.” The website summarizes cleanup progress at the Site.
Public comments on the ROD are contained within the ROD, along with the EPA’s responses (ROD Appendix A, Responsiveness Summary). For the FYR processes, the EPA encouraged the public to submit comments through the postal service and email.
3.5 Summary of Communication Needs
No members of the public responded to notices, or door-to-door attempts, of the Second or Third FYR processes as a result of the posted public notices. A Fourth FYR will be completed for the site in 2021; the EPA will invite community participation again at that time.
The Third FYR Report also recommended that moving the local information repository from the University of South Florida Library to a public library be considered to improve accessibility for the public.

The 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 and active involvement by the community in the cleanup process. The EPA will implement the community involvement activities described below that are based on previous investigations and public concerns. It is the EPA’s objective to solicit, listen to, and respond to suggestions about cleanup at the Site. Each suggestion identified during the interviews will be responded to with a set of tools that EPA will use to improve communication and active involvement in the cleanup process.
4.1 Long-Term Monitoring
An ongoing part of the Superfund process is the production of FYR reports to evaluate the success of remediation and to monitor the performance of long-term operations. The EPA analyzes sampling results and observations and applies technical expertise when developing recommendations and conclusions for FYR reports. The reports determine whether the selected remedial actions are protective of human health and the environment. Interviews of community members are an integral part of the FYR process. They provide the EPA with valuable insight and suggestions. The EPA will use the following tools to address the issue of long term monitoring of the Site and the community’s involvement.
Develop Five-Year Reviews
• Objective: Prepare and distribute ongoing comprehensive FYR reports for the Site to evaluate the implementation and performance of Site remedies and determine whether they remain protective of human health and the environment. • Method: The most recent FYR Report for the Site that can be found in both information repositories (at the University of South Florida Library and at EPA Region 4’s offices in Atlanta). The EPA will notify the public in the local newspaper when the next FYR report is available. • Timing: The EPA will prepare and make available FYR reports every five years so long as there remain on-site hazardous substances, pollutants, or contaminants above levels that allow for unlimited use and unrestricted exposure at the Site.
Conduct interviews during production of future Five-Year Reviews
• Objective: Provide an opportunity for the EPA to solicit knowledge and understanding from those involved in cleanup and from the community about the protectiveness of remedial activities at the Site. • Method: The EPA will schedule interviews with people willing to participate in the interview process. • Timing: Interviews will be conducted every five years as part of the FYR process.
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 16 4.2 Partnership Development
The EPA’s CIC is available to support partnership development for the community for matters relating to the Site. The EPA’s methods for supporting partnerships that increase the breadth of understanding and the level of involvement are defined below.
Designate an EPA CIC
• Objective: Provide a primary liaison between the community and the EPA and to ensure prompt, accurate, and consistent responses and information dissemination about the Site. In instances where EPA’s CIC may be unable to provide adequate information (such as on technical issues), the CIC will direct inquiries to the appropriate EPA contact. • Method: The EPA’s CIC will support partnership development, handle site inquiries, and serve as a point of contact for community members. The CIC is appointed by the Region 4 Headquarters. L’Tonya Spencer-Harvey is the EPA CIC assigned to the Site who works closely with the EPA RPM, Carter Owens. • Timing: The CIC will be available until the Site is officially closed.
Provide opportunities to involve community groups in cleanup at the Site
• Objective: Share information with and collect ideas from local community groups to address mutual concerns, engage in constructive dialogue, and increase involvement in environmental cleanup decision making at the Site. • Method: When appropriate, the EPA will support gatherings of community groups or others and provide materials and expertise for stakeholders that attend. • Timing: As needed and as appropriate.
Prepare and distribute Site Fact Sheets and technical summaries
• Objective: To provide community groups and interested community members with current, accurate, easy-to-read, easy-to-understand information about the Site. • Method: Fact Sheets will be created and mailed to all parties on the site mailing list and/or distributed to partnership members. In addition, copies will be available in the information repositories. • Timing: The EPA will prepare and distribute Fact Sheets as needed.
4.3 Enhance Communication
The EPA has established a variety of communication methods that help refine communication with the community. The Administrative Record is available to the public and is the compilation of information used in selecting the preferred cleanup remedy, the ESD, and includes the Final CIP and FYR Reports. The Administrative Record for the Site is located in the information repositories (locations in Appendix I). Technical information may be obtained by contacting the CIC (contact information is in Appendix A) who may redirect requests to appropriate sources of
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 17 information. Additionally, the EPA’s website provides information to those with computers (see link in Section 3.4), and the mailing list may be another means to convey meeting information, announce cleanup milestones, or comment periods. CIP updates involve evaluating and improving the Community Involvement Program. EPA’s use of all these tools to enhance communication are described below.
Establish and maintain the Administrative Record
• Objective: Provide residents with a paper trail of all documents, resources, and material used by the EPA’s RPM and the Site Team in reaching all decisions about the Site and the cleanup. • Method: The EPA will provide at least two sets of the Administrative Record for the Site, one in the EPA Region 4 offices located at 61 Forsyth Street, SW, Sam Nunn Atlanta Federal Center, 9th Floor, Atlanta, Georgia, and the other in the local information repository in the University of South Florida Library, 4202 E. Fowler Avenue, Tampa, Florida. • Timing: The Administrative Record is open and will remain open until the Site receives closure status.
Establish and maintain Information Repositories
• Objective: To provide a convenient location where residents can go to read and copy official documents and other pertinent information about the Site and the EPA’s activities. • Method: The repository is a reference collection of site information containing the Administrative Record file, other site-specific information, the CIP, and information about the general Superfund process. The CIC will work with a local contact to maintain the local repository. This repository will be accessible to the physically challenged, will have copier facilities, and will be available to residents during normal business hours and at least some evening and/or weekend hours. Additionally, an information repository is available at the EPA Region 4 offices in Atlanta, Georgia. • Timing: The EPA established the local repository located in the University of South Florida Library, in 1995. The EPA continues to add new documents to the repository as they become available.
Provide Site and Superfund information on the Internet
• Objective: Provide key resources for searching and listing both general and specific information about Superfund and hazardous waste issues. • Method: The following include methods to locate Site and Superfund information on the internet: ♦ A Site Status Summary for the site can be found at: https://www.epa.gov/superfund/helena-chemical
______Helena Chemical Company (Tampa Plant) Superfund Site August 2020 Community Involvement Plan Page 18 ♦ Information about the EPA and Superfund can be found through the EPA’s website at http://www.epa.gov ♦ Information about the Site can also be accessed via EPA Region 4’s website at https://www.epa.gov/aboutepa/about-epa-region-4-southeast ♦ The Proposed Plan and the ROD for the Site are also on the internet as they are completed at: https://www.epa.gov/superfund/search-superfund-decision- documents
• Timing: Site Status Summaries are periodically updated.
Maintain an updated mailing list for the Site
• Objective: Facilitate the distribution of site-specific information to everyone who needs or wants to be kept informed about the Site. • Method: The EPA will update the site mailing list that includes all residences located adjacent to the Site, in known or suspected paths of contaminant migration, or those otherwise affected by the Site. The EPA will also solicit interested parties during interviews, public meetings, and public availability sessions. • Timing: The EPA will review and revise the mailing list periodically to keep it current.
Revise CIP
• Objective: Identify and address community needs, issues, or concerns regarding the Site. As FYRs occur, the CIP will undergo revision. • Method: Community interviews will serve as the basis for CIP revisions and improvement of the Community Involvement Program. • Timing: Revisions occur with each FYR.
