This memorandum documents the U.S. Environmental Protection Agency's performance, determinations, and approval of the Tulsa Fuel and Manufacturing Superfund Site (Site) first five year review under Section 121(c) of the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S. Code Section 9621(c), as provided in the attached first Five-Year review Report.  

Summary of the first Five-Year Review Report
The 2008 Record of Decision required contaminated waste from the Site to be placed into an on-site consolidation cell. Following the completion of remedial action at the Site in 2017, operation and maintenance (O&M) activities have been conducted as intended. O&M activities include groundwater monitoring to ensure that the contents of the consolidation cell have not leached into groundwater, and inspection of the Site to ensure the physical integrity of the cell. To date, groundwater monitoring indicates that groundwater has not been impacted by site-related waste. Institutional controls should remain in place and continue to be enforced. The remedy is performing as expected and continues to achieve remedial action objectives.

Environmental Indicators
Human Exposure Status:  Human Exposure Under Control
Contaminanted Groundwater Status: Contaminated Groundwater Migration Under Control
The Site is Sitewide Ready for Anticipated Reuse

Determination
I have determined that the remedy for the Tulsa Fuel and Manufacturing Superfund Site is protective  of human health and the environment.  This five-year review report specifies that there are no actions that need to be taken for the remedy to remain protective in the long term.

I. INTRODUCTION

The purpose of a Five-Year Review (FYR) is to evaluate the implementation and performance of a remedy in order to determine if the remedy is and will continue to be protective of human health and the environment. The methods, findings, and conclusions of reviews are documented in FYR reports such as this one. In addition, FYR reports identify issues found during the review, if any, and document recommendations to address them.

The U.S. Environmental Protection Agency (EPA) is preparing this FYR pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 121, consistent with the National Contingency Plan (NCP)(40 CFR Section 300.430(f)(4)(ii)), and considering EPA policy. 

This is the first FYR for the Tulsa Fuel and Manufacturing Superfund Site. The triggering action for this statutory review is the on-site construction start date of the remedial action. The FYR has been prepared due to the fact that hazardous substances, pollutants, or contaminants remain at the Site above levels that allow for unlimited use and unrestricted exposure (UU/UE). 

The Site consists of a single operable unit that will be addressed in this FYR. The Site remedy resulted in the cleanup of soil, sediment, and surface water.

The Tulsa Fuel and Manufacturing Superfund Site Five-Year Review was led by the Oklahoma Department of Environmental Quality. Participants included representatives of the DEQ and EPA. The review began on 10/1/2018.

Site Background 
The Tulsa Fuel and Manufacturing (TFM) Superfund Site was formerly operated as a zinc smelter and lead roaster industrial facility from 1914 through 1925. In 1999, EPA placed this Site on the National Priorities List (NPL) in an effort to remediate areas affected by heavy metals and to prevent potential contamination of surface water, sediment, and groundwater in the area. The Site is located in northeastern Oklahoma approximately 1-1/3 miles south of downtown Collinsville in Tulsa County, Oklahoma. Figure 1 shows a map of the approximately 61-acre site.

II. RESPONSE ACTION SUMMARY

Basis for Taking Action
The basis for taking action at the Site was to protect human health and the environment. The contaminants of concern (COCs) for the Site were identified as arsenic, cadmium, and lead. During the remedial investigation, a human health risk and ecological risk assessment was conducted that showed an excess lifetime cancer risk range greater than 1 in 10,000 to one in one million and a non-carcinogenic Hazard Index > 1 for various risk scenarios. The risk assessment determined that cleanup levels for the COCs were to be governed by the risk to human health because human health risk areas and ecological risk areas were co-located. Populations reasonably expected to be present at the Site are: adult and child residents, youth trespassers, outdoor commercial/industrial workers, and construction/utility workers (USEPA 2008). Table 1 below describes the human health benchmarks.

Response Actions
In November 1992, the Oklahoma State Department of Health conducted a focused Preliminary Assessment (PA) under the direction of the EPA as part of a multi-site cooperative agreement. In May 2001, voluntary blood lead testing was conducted on children from six months to six years of age. In September 2001, after the potentially responsible party (PRP) declined to conduct the remedial investigation/feasibility study (RI/FS), the EPA and DEQ negotiated a cooperative agreement in which DEQ assumed the role of lead agency for the RI/FS with the EPA acting as the support agency.  In 2003, unilateral administrative orders for access and noninterference were issued to two property owners of the Site, and site access was granted (BMcD, Oct. 2017). In 2004, a perimeter fence was installed as an emergency response action to secure the Site.  No removal actions have been conducted. A detailed site chronology is presented in Appendix G. 

In 2008, a Record of Decision (ROD) describing the selected remedy for the Site was issued by the EPA (BMcD, Oct. 2017).  The ROD established the following Remedial Action Objectives (RAOs) for the selected remedy (USEPA 2008):

 Soil and Waste Materials: Protect human health by preventing direct contact, through the ingestion and inhalation exposure pathways, with arsenic, cadmium, and lead contaminated on-site and off-site soil and waste material by reducing arsenic, cadmium, and lead concentrations to residential levels less than 37 ppm, 75 ppm, and 500 ppm respectively, or to nonresidential levels less than 200 ppm, 560 ppm, and 1,000 ppm respectively.

 Sediment: Protect human health and the environment by preventing direct contact, through the ingestion pathway, with arsenic, cadmium, and lead contaminated sediment by reducing arsenic, cadmium, and lead concentrations to levels less than 181 ppm, 813 ppm, and 500 ppm, respectively.

 Surface Water: Protect human health and the environment by preventing direct contact, through the ingestion pathway, with cadmium contaminated surface water by reducing cadmium concentrations to levels less than 238 ppb.

In June 2015, a ROD Amendment was finalized to waive Oklahoma Administrative Code (OAC) 252:515-11-3, allowing for construction of the consolidation cell without the minimum five-foot vertical separation between the highest groundwater elevation and the lowermost waste surface; and to remove sediment treatment as a component of the remedy (BMcD, Oct. 2017). For both of these changes, it was determined that the amended remedy would attain an equivalent level of protection. The ROD Amendment did not alter the original RAOs identified in the 2008 ROD (USEPA 2015). 

To achieve RAOs, the major remedy components for the Site, as selected in the 2008 ROD and modified in the 2015 ROD Amendment, were the following (USEPA 2015):

 Soil and Waste Material: On-site remedy components consisted of consolidation and on-site capping of soil and waste material exceeding cleanup levels. Confirmation soil sampling was conducted in each area of excavation to ensure cleanup levels were met and all contaminated soil and waste material was removed. 

 Sediment and Surface Water: On-site ponds, mid-site ravine, and strip mine pit remedy components consisted of on-site disposal of material exceeding the cleanup levels for sediment and surface water. Sediment was dewatered, excavated, and analyzed according to toxicity characteristic leaching procedures (TCLP), and consolidated on-site. Confirmation sediment sampling was conducted after excavation to ensure cleanup levels were met and all contaminated sediment was removed. 

 Off-Site Soil. Sediment, and Waste Material Locations: Off-site excavation and disposal was conducted for waste material exceeding the cleanup levels for soil, sediment, and waste material. This off-site waste material was analyzed via TCLP and consolidated on-site. Confirmation sampling was conducted after excavation to ensure cleanup levels were met and all contaminated soil, sediment, and waste material was removed. 

Long-term monitoring, Site inspections, operation & maintenance (O&M), institutional controls (ICs), and Five-Year Reviews were required due to the consolidation and capping of waste materials on-site. 
Status of Implementation
In 2017, the remedial action (RA) for the cleanup of metals at the Site was completed.  Approximately 186,000 yd[3] of contaminated soil, sediment, and waste were placed into an on-site consolidation cell. On-site soil excavations were the major contributor to cell volume, but contaminated soils from off-site locations to the north, west, and southeast were also placed into the cell. Contaminated soils that are contiguous with the Site are part of the TFM off-site locations (USEPA 2008). The consolidation cell was surrounded by a five-strand barbed wire fence. Four groundwater monitoring wells were installed (Figure 1)(ODEQ, Aug. 2018). Groundwater at the Site has not been impacted by site-related waste, so groundwater was not remediated; however, a long-term monitoring program was established that requires recurring groundwater monitoring to ensure the COCs continue to be effectively contained within the consolidation cell. Site inspections, operation & maintenance, five-year reviews, and institutional controls, in addition to groundwater monitoring, are all required for as long as waste material continues to be present on-site within the consolidation cell (USEPA 2015).

Contaminated soils and sediment were excavated until confirmation sampling showed that cleanup levels had been achieved, and then backfilled to varying degrees based on the design of the stormwater runoff grading. Exceptions to this occurred at the following locations (Appendix B):

 where excavation was only carried out to 1-2 ft, because waste was excavated by using only visual
inspection for waste identification, such as the strip mine pit banks and the southern portion of the T-37 length of land adjacent to the railroad.

 where no excavation was carried out due to concerns for safety of access by the construction crew, or due to the proximity of the railroad. These locations are within the T-37 area (to the north east of the T-37 portion mentioned above), at multiple sidewall locations adjacent to the railroad, and also approximately 300 ft to the north of the consolidation cell at a corner of the Site's chain-link perimeter fence. 

 Although sampling carried out near the start of the RA indicated that TFM-related waste areas extend onto the right-of-way of the adjacent railroad, the company that operates the railroad, Watco Companies, LLC, has declined to allow cleanup activities on its property. Further investigation of the railroad right-of-way has been deferred to EPA's Superfund Site Assessment program.

The following engineering controls are currently in place and must be maintained to ensure the protectiveness of the remedy: an engineered consolidation cell cap, groundwater monitoring wells, and fencing around the consolidation cell area.  

The ROD required institutional controls to be placed on the Site to protect the remedy (Table 2). The Site was cleaned up to standards for residential reuse, with the exception of the fenced-in consolidation cell area, and also a length of land adjacent to the railroad to the southeast where institutional controls (ICs) have been placed to limit use (Appendix B).  After completion of the RA, the specific components of the institutional controls were finalized. The table below describes these institutional controls. The Notice of Remediation for the Site property is provided in Appendix C.

                     Notice of Remediation, September 2017

Systems Operations/Operation & Maintenance
O&M has encompassed the following: quarterly groundwater monitoring to ensure that the contents of the consolidation cell have not leached into groundwater; and inspection of the Site to ensure that there are no erosion problems, no settling on the cell, and that cell vegetation remains healthy. Future groundwater monitoring will be conducted on a yearly basis. O&M may include any maintenance of the consolidation cell and site drainage features that is deemed relevant and necessary (ODEQ, Jan. 2018). This maintenance may consist of grading, mulching, seeding, sodding, mowing, backfill importing, controlling pests, removing drainage blockages, installing rip-rap, and installing rock & brush dams. To date, no problems in the implementation of O&M have been encountered that would require such maintenance, though routine mowing has been implemented and continued as a preventative measure to ensure that trees do not grow on the consolidation cell and to control pests.

In the Spring of 2019, after reaching an agreement with the property owner of the Site, a cooperative of local businesses installed honey bee hives on the Site to facilitate honey making operations. There is currently no concern that these operations could negatively impact the structural integrity of  the consolidation cell. The owner of the property and the owners of the honey bee hives are aware of the restrictions specified in the institutional controls (see Appendix C). The presence of honey bees should facilitate pollination and provide ecological benefits to the surrounding area. The major property owner is actively engaged in finding other opportunities for redevelopment.

III. PROGRESS SINCE THE LAST REVIEW

This is the first five-year review report for the Site.

IV. FIVE-YEAR REVIEW PROCESS

Community Notification, Involvement & Site Interviews
A public notice of the five-year review process was made available by newspaper release on 12/5/2018 in the Tulsa World (Appendix H), mailing notices to homes, leaving notices at the Tulsa Fuel and Manufacturing Superfund Site information repository at the Collinsville Public Library, and by email. These notices invited the public to submit any comments to the EPA via DEQ. Additionally, the results of the FYR and this report will be made available at the Collinsville Public Library, 1223 West Main Street, Collinsville, OK 74021. 

During the FYR process, interviews were conducted to document any perceived problems or successes with the remedy that has been implemented to date. This interview process consisted of reaching out to nearby residents, city and county officials, and governmental organizations for feedback. 

None of the interviewees responded that they were displeased with any element of the remedy, that they had any pressing concerns, or that they knew the community had been negatively impacted by the cleanup activities. Multiple interviewees mentioned the local news media coverage that became especially publicized during the RA. The property owner gave an account of attractive nuisance trespassing at the Site for the purposes of fishing in the flooded strip mine pit, and he suggested that completing the Site's perimeter chain-link fence would deter trespassing. This chain-link fence, which is different from the barbed-wire fence that surrounds the cell, uses the strip mine pit as a natural barrier along the entire southern perimeter. Interviewees responded that they felt well-informed about the Site by the DEQ and EPA. 

No continued or unresolved issues were discovered during the interview process. Completed interview questionnaires are provided in Appendix D. 

Data Review
Groundwater was not a component of the remedy set forth in the ROD, so there are no RAOs to be met for groundwater. Nevertheless, as part of regular O&M of the Site, groundwater monitoring has been implemented and conducted to ensure the integrity of the consolidation cell by verifying that the waste contents of the cell have not leached into groundwater. 

Analytical results show that the consolidation cell continues to contain its waste, and no abnormal occurrences have been observed that would trigger contingencies. There are currently no readily observable trends of concern. Following construction completion in October of 2016, groundwater sampling events have not yielded exceedances of Safe Drinking Water Act MCLs for COCs in monitoring wells (Appendix I). Groundwater monitoring up to and including the year 2019 is expected to establish a baseline dataset by which a statistical analysis can be undertaken. Groundwater elevation measurements indicate that groundwater continues to flow generally to the southeast towards Blackjack Creek. 

Site Inspection
The inspection of the Site was conducted on 11/29/2018. In attendance were Michael Torres - EPA, Amy Brittain - DEQ, and Michael Lea - DEQ. The purpose of the inspection was to assess the protectiveness of the remedy.

The Site remedy has continued to operate as intended. Vegetation is well established, the Site drainage features remain operational, and the consolidated waste within the cell continues to be effectively contained. There are no issues with ponding, erosion, burrowing or cracks in the consolidation cell cap. Although erosion gullies and some poorly vegetated areas were observed at the strip mine pit and south of the cell access road, respectively, at the conclusion of the RA, the progress of this erosion has stabilized. Consolidation cell fencing is in good condition and completely encloses the cell. There is no damage to the well casing, pad, or locks of any of the four monitoring wells. The Site Inspection Checklist is provided in Appendix E. Photographs taken during the Site inspection are presented in Appendix F. 

V. TECHNICAL ASSESSMENT

QUESTION A:  Is the remedy functioning as intended by the decision documents?

Question A Summary:
The remedy has been functioning as intended by the ROD and amended ROD. The contaminated soil, sediment, and waste material has been consolidated and capped on-site, and groundwater monitoring has not shown that site-related contamination has infiltrated the groundwater. 

Required O&M is being carried out to ensure the structural integrity of the consolidation cell by inspecting the cell and monitoring groundwater. O&M Site inspections have shown that Site grading and drainage features provide for adequate runoff, and the cell is generally well-vegetated without erosion. Institutional controls are in place on the Site, and they are functioning as intended. No evidence of trespassing or physical disturbances on the cell have ever been observed. Post-cleanup, no members of the community or local government have expressed that the remedy is not meeting their pubic health and environmental protection needs. 

Institutional controls required by the ROD are in place and appear to be effective.

QUESTION B:  Are the exposure assumptions, toxicity data, cleanup levels, and remedial action objectives used at the time of the remedy selection still valid?

Question B Summary:
The remedy set forth in the ROD established RAOs to addresses all current and potential future residential risks associated with exposure to soil, sediment, surface water, and waste. The remedy is currently achieving RAOs. There are no newly promulgated Applicable or Relevant and Appropriate Requirements (ARARs) since the 2015 ROD Amendment. There have been no changes in the land use of the surrounding areas. The Site remains in an area of residential interest, so it continues to be reasonable that future land use for the Site may be residential. 

The majority of areas with ecological receptors for potential Site contamination continue to be co-located with areas where human health risk is of importance, so human health risk continues to govern the protective cleanup levels at the Site. The ROD Amendment declared that COCs at the Site presented both an excess lifetime cancer risk range greater than 1x10[-4] and a non-carcinogenic Hazard Quotient greater than 1 for several risk scenarios. The website for the Superfund Chemical Data Matrix (SCDM) provides a Change Control and Errata Sheet that shows that the parameters used to determine risks for the COCs have not been modified since the 2015 ROD Amendment (SCDM 2019). Similarly, EPA's Integrated Risk Information System website shows that the last significant revision to risk parameters for the COCs was in 2004 (IRIS 2019). There are no changes in exposure pathways (ingestion and inhalation) or assumptions for receptors specified in the ROD: adult and child residents, trespassers, outdoor commercial/industrial workers, construction/utility workers, and recreationists. There have been no changes in the physical conditions of the Site or contaminant characteristics that would affect the protectiveness of the remedy. There are no newly identified contaminant sources. The preceding findings confirm that the numerical cleanup levels and RAOs derived from risk calculations in the original risk assessment are still valid.

QUESTION C:  Has any other information come to light that could call into question the protectiveness of the remedy?

No additional information has been identified that calls into question the protectiveness of the remedy.
            
            

VI. ISSUES/RECOMMENDATIONS

There are no issues or recommendations that affect current or future protectiveness.
OTHER FINDINGS

There are no other findings that affect current or future protectiveness.
      
VII. PROTECTIVENESS STATEMENT

                       Sitewide Protectiveness Statement
Protectiveness Determination:
Protective

Protectiveness Statement:
The remedy implemented at the Site is currently protective of human health and the environment. Areas of the Site where waste was left in place remain below uncontaminated soil and vegetation continues to grow. Institutional controls are in place to restrict use and access at the consolidation cell area.

APPENDIX G  -  SITE CHRONOLOGY 

The TFM Superfund Site was identified during a formal study of zinc smelters in the state of Oklahoma.  Discovery related to the TFM Superfund Site occurred in July 1992.  Regulatory activities related to the TFM Superfund Site include the following (BMcD, Oct. 2017):
 November 1992:  OSDH conducted a Preliminary Assessment under the direction of the United States Environmental Protection Agency (EPA) as part of a Multi-Site Cooperative Agreement (CA# V-00645-01)
 September 1994:  DEQ conducted a focused Site Inspection (SI) under the direction of EPA.
 August  -  September 1998:  Search for potentially responsible parties (PRPs) was conducted.
 September 1998:  Hazard Ranking System (HRS) Documentation was completed by EPA.
 September 29, 1998:  Site was proposed to the Superfund National Priorities List (NPL).
 January 19, 1999:  Final listing of the TFM Superfund Site to the NPL.
 May 1999:  A Removal Assessment Report was completed by EPA Superfund Technical Assistance and Response Team (START).
 July 27, 1999:  A public meeting to inform concerned citizens about the TFM Superfund Site was held by EPA in conjunction with DEQ and the Agency for Toxic Substances and Disease Registry (ATSDR).
 July 27, 2000:  The Public Health Assessment for Tulsa Fuel and Manufacturing was finalized by ATSDR.
 July  -  October 2000:  EPA issued Special Notice Letter to PRP with follow-up meeting, clarifications regarding EPA's Enforcement Position, and copies of the Removal Assessment Report.
 January 24, 2001:  DEQ press release regarding the TFM Superfund Site was published in the Collinsville News.
 May 21  -  22, 2001:  Voluntary blood lead testing was conducted on children from 6 months to 6 years of age.
 September 2001:  After the PRP declined to conduct the remedial investigation/feasibility study (RI/FS), the EPA and DEQ negotiated a cooperative agreement in which DEQ assumed the role of lead agency for the RI/FS with the EPA acting as the support agency.
 May  -  August 2003:  Unilateral Administrative Orders for Access and Noninterference were issued to two property owners of the TFM Superfund Site, and Site access was granted.
 2005  -  2007:  The RI/FS was performed under the direction of DEQ.
 November 24, 2008:  A Record of Decision (ROD), describing the selected remedy for the TFM Superfund Site, was issued by the EPA.
 2012  -  2014:  DEQ lead the remedial design (RD) activities under the original cooperative agreement.
 June 2015:  A ROD Amendment was finalized in June 2015 to (1) waive Oklahoma Administrative Code (OAC) 252:515-11-3 and construct the consolidation cell without the minimum five-foot vertical separation between the highest ground water elevation and lowermost waste surface; (2) remove sediment treatment as a component of the remedy; and (3) implement all other remedy components as stated in the 2008 ROD.
 2015  -  2016:  The RA was initiated in April 2015.  Construction of the consolidation cell was completed in August 2016.  Site restoration and RA contractor demobilization was completed in October 2016 (BMcD, Oct. 2017).  
 August 30, 2016  -  September 30, 2017:  Remedy Operational and Functional (O&F) period
 September 2016:  Preliminary Close Out Report (PCOR) issued by EPA
 October 1, 2017:  O&M activities began.  
 January 1, 2018:  DEQ took over O&M monitoring activities from Burns & McDonnell Engineering Company, Inc (BMcD).
 April 2019: Shadow Mountain Honey Company and Ide's Gary Avenue Gold installed honey bee hives north of the on-site consolidation cell and began conducting honey making operations.
