1.0 INTRODUCTION

This final design work plan for the sediment operable unit (SOU) remedial action for the FieldsBrook site located in Ashtabula, Ohio, has been prepared to meet the requirements of thestatement of work (SOW) Section 8 (86C3609A-703 dated March 1989) and is a stand-aloneattachment to the preliminary (30-percent) design report. This final design work plan defines theinterfaces, work tasks, project deliverables, milestones, and schedules associated with preparingthe remedial design for excavation of sediment from Fields Brook, thermal or stabilizationtreatment of the sediments, and storing the treated sediment onsite within a containment cell. Italso identifies the process that will be used to develop procedures, specifications, and drawings.The design process includes adhering to standard engineering procedures, modifying existingdocuments where possible, involving construction and field remediation personnel in reviews,developing construction work plans and schedules that minimize time in the field, andcoordinating with the Fields Brook Potentially Responsible Parties Organization (FBPRPO) andregulatory agencies.

This work plan is organized into 12 sections. Section 2.0 describes the site location and features,as well as a brief history of the site. Section 3.0 presents the project objectives, which includepreparation of a preliminary design report and an intermediate (60-percent), prefmal (90-percent),and final (100-percent) design. Section 4.0 summarizes regulatory requirements and compliancedocuments including applicable or relevant and appropriate requirements (ARARs), which willhave been developed in the preliminary (30-percent) report. Section 5.0 discusses the projectorganization. Section 6.0 discusses the approach to quality assurance during remedial design.Section 7.0 presents the health and safety plans for the remedial design period. Section 8.0presents the scope of work. This section details six tasks, which include special conditions,general requirements, site work, special construction, drawings, and bid specifications anddocuments. Section 9.0 discusses project management activities during remedial design includingdocument control, review meetings, and progress reporting. Section 10.0 provides the projectschedule and the information that will be provided with the intermediate (60-percent), prefinal(90-percent), final (100-percent) submittals and content of the proposal package. Section 11.0presents a list of contingencies to the final design.

Revision of the discussions, concepts, and approaches presented in this work plan may benecessary as work progresses.

2.0 BACKGROUND

2.1 SITE LOCATION AND DESCRIPTION

Fields Brook is located in Ashtabula, Ashtabula County, in northeastern Ohio (Figure 2-1). Thebrook drains a 5.6-mile2 watershed, the eastern portion draining Ashtabula township and thewestern portion draining the city of Ashtabula (Figure 2-2).

The 3.5-mile stretch of main channel begins just south of U.S. Highway 20, about 1 mile east ofState Highway 11. From the main channel, the stream flows northwesterly, under Highway 20and Cook Road, to just north of Middle Road. Then the stream is made up of a series of reaches(Figure 2-3) and flows westerly to its confluence with the Ashtabula River. From Cook Road

downstream to Highway 11, the stream flows through an industrial area. Fields Brook variesgreatly in width and depth. Some areas surrounding the brook are thickly covered withvegetation.

2.2 SITE HISTORY

Industrial sources have contaminated the sediment in Fields Brook with a variety of organic andheavy metal pollutants. Volatile organic compounds found in sediment sampled during earlierstudies of Fields Brook include the following: chlorobenzene, 1,1,1-trichloroethane, 1,1,2-trichloroethane, 1,1-dichloroethane, tetrachloroethane, and vinyl chloride. The following base-neutral compounds were found: hexachloroethane, hexachlorobutadiene, toluenediamine, andtoluene diisocyanate. The chlorinated benzene compounds found were 1,2,4-trichlorobenzene andhexachlorobenzene. Polychlorinated biphenyls (PCBs) were also found. Metals (zinc, mercury,chromium, lead, and titanium) have also been found in the sediment at concentrations reported bythe U.S. Environmental Protection Agency (EPA) in the Toxic Summary Report (April 1982) tobe above background. EPA reports that the amount of contamination currently entering thebrook has been substantially reduced due to the recent development of pollution control laws anddischarge permitting requirements.

The Fields Brook site was first proposed for inclusion on the National Priorities List (NPL) inOctober of 1981. It was included in the NPL in September of 1983, with a Hazard RankingSystem score of 44.95.

2.3 SITE ACCESS

Site access to the central remediation facilities (treatment area and containment cell) andtemporary facilities (haul roads, tire washes, etc.) will be provided by the FBPRPO and/or EPA.FBPRPO will provide access agreements to the remedial action contractor for all properties undertheir control, and EPA will provide access agreements for public land and any other land notbeing controlled by the FBPRPO.

The containment cell and treatment areas will be located on the ACME Scrap Metal site. Theactual layout and arrangement of the containment cell and treatment area will be developed aspart of the preliminary design report. A conceptual arrangement is shown on Figure 2-4.

The remedial action contractor will be responsible for providing security at the site to controlaccess to the site, prevent unauthorized entry, and maintain visitor records. Security measureswill include restricting site access to authorized personnel using fencing and/or security guards.Personnel entering the exclusion zone will be limited to those people as specified in the healthand safety plan. The exclusion zones will include the areas of the brook being excavated,temporary stockpiles, treatment areas, containment cell, and any other area being disturbed that isconsidered contaminated.

Access to the treatment and landfill site will be limited to two entrances. One entrance will beused for all nonconstruction vehicles. The existing entrance and parking lot will be used toprovide access and parking for construction workers and support personnel vehicles. A secondentrance will be constructed for the use of construction vehicles (dump trucks, heavy equipment).

3.0 PROJECT OBJECTIVES

The primary objective of this project is to develop a remedial design for the SOU of the FieldsBrook site in accordance with a Unilateral Administrative Order issued by EPA (March 22, 1989)under Section 106 of the Comprehensive Environmental Response, Compensation, and LiabilityAct (CERCLA). The scope includes preparation of a preliminary design report, which includesthis final design work plan as a stand-alone document. Preparation of the preliminary(30-percent) design report is dependent on the completion of SOU design investigations.

The objective of this work plan is to provide the process for development of the remedial design.Final design work will include intermediate, prefinal, and final design phases, representing60-percent, 90-percent, and 100-percent completion, respectively. At the 100-percent completionstage, reproducible drawings and specifications will be ready for bid advertisement.

The scope of the final design will include preparing the performance specifications and definingthe requirements for supporting activities to accomplish:

• Removal of sediment from Fields Brook that exceeds the clean up goals designated inTable 3-1

• Thermal treatment of excavated sediment that exceeds the level designated for thermaltreatment in Table 3-1

• Stabilization of the excavated sediment that does not require thermal treatment as designated inTable 3-1

• Disposal of treated sediment in an onsite containment cell

The final design will comply with all ARARs identified in the preliminary (30-percent) designreport and will be consistent with the September 30, 1986, record of decision (ROD).

4.0 REGULATORY COMPLIANCE

Federal, state, and local agencies will be contacted to determine the actions required to meet thesubstantive requirements of the ARARs. This determination will take place as part of thepreliminary (30-percent) design report. Potentially applicable sections of the regulations areidentified in the following subsections but may be substantially affected by the preliminary designreport investigation into ARARs.

4.1 FEDERAL REGULATIONS

ARARs do not apply to pre-Superfund Amendments and Reauthorization Act (SARA) RODs.Section 121(b) of SARA explicitly states that Section 121 (which includes the requirements tomeet ARARs) does not apply to RODs issued prior to October 17, 1986 (the date SARA wasenacted). The Fields Brook ROD was signed September 30, 1986. ARARs, as defined bySARA, are not legally applicable to this site.

A248.F

Table 3-1 Sediment Cleanup and Treatment Levels (to be developed later)

A248.F

There are two different types of ARARs: those originally specified by the 1985 NationalContingency Plan (50 FR 47917) and those specified by SARA. Although ARARs, as defined bySARA, are not legally applicable to the site, the 1985 ARARs are applicable.

SARA requires all remedial actions to meet ARARs unless a waiver has been granted. The 1985ARARs were used as general guides in determining the extent of the remedial action(50 FR 47917). Thus, the 1985 ARARs were much more flexible in their application than theSARA ARAR. The ARARs in the 1985 NCP were and are, with respect to Fields Brook, less"binding" than the SARA ARARs.

Even for post-SARA ARARs, once a ROD is signed

EPA will not reopen that decision unless the new or modified requirements calls into questionthe protectiveness of the selected remedy... The policy of freezing ARARs will help avoidconstant interruption, re-evaluation, and re-design during implementation of selectedremedies.1

EPA explicitly recognizes that "design of the remedy...is based on ARARs identified at thesigning of the ROD."2 Nothing in EPA written policy suggests otherwise. This policy applieswith even more force for pre-SARA RODs.

The FBPRPO believe that many of the EPA regulations are ARARs, even pursuant to the 1985NCP, and have incorporated them into their submissions. This determination must be made on acase-by-case basis.

The following is a list of potential ARARs based on the 1985 NCP, which will be refined in thePreliminary Design Report.

5.0 DESIGN PROJECT ORGANIZATION

The design contractor is responsible for producing a final remedial design document that includesdrawings, specifications, and supporting plans or requirements for plans. The design team,working under the direction of a project manager and project engineer, will develop the remedialdesign documents. The project team is organized as shown in Figure 5-1.

The design contractor's project manager has primary responsibility for the overall technical,financial, and administrative performance of the program. He is the primary point of contact onall contract-related matters. Other responsibilities include cost and schedule reporting andcontrol; preparing status reports and program reviews; and certifying claims for reimbursement(invoices). The design contractor's project manager reports to the FBPRPO or itsrepresentative(s).

The project engineer reports directly to the project manager and acts in the project manager'sabsence. The project engineer is ultimately responsible for all technical aspects of the work. Hewill delegate the appropriate authority to the project team, providing them with the freedom toexercise their responsibilities and use their technical expertise. He will review all technical andprogrammatic activities to ensure that quality is maintained and goals are achieved. He will, inaddition, make timely changes or modifications dictated by evolving project needs.

The design discipline supervisors assigned to the project team report to the project engineer.They are responsible for carrying out and supervising the technical work within their respectivedisciplines. They will ensure that design documents are prepared in accordance with applicableengineering procedures as identified in the quality assurance plan.

The project control supervisor reports to the project manager and will prepare all projectestimates and schedules. He will also collect and analyze cost and schedule performance dataneeded to ensure that project milestones are met.

The quality assurance representative is independent from project operations and reports directly tothe manager of quality assurance. The quality assurance manager directs and controls the projectquality assurance program and works with the project manager to coordinate its application. Thequality assurance manager is responsible for development of the quality assurance/quality controlplan and monitoring its implementation.

Specialty subcontractors will be used as needed to provide consultation and review of relevantdesign work. Specialty subcontractors, ENRECO and FOCUS, have been employed forstabilization and thermal treatment, respectively. The integration of the subcontractors into theproject team is shown in the organization chart on Figure 5-1. The executing stabilization andthermal treatment contractors will be determined in a future phase of the remedial action.

• Site preparation, which will include disposal of noncontaminated rubbish (scrap metal, wood,etc.) associated with the site. Other activities will include providing laydown areas, temporarystorage areas, haul roads, treatment areas, detention ponds, office trailers, anddecontamination facilities.

• Clearing, which will include removing ail vegetation to within 2 in. of the existing groundsurface. The trees and brush will be chipped and disposed of onsite in a designated area.Stumps will only be removed from areas if required to establish a suitable subbase. Stumps inthe excavation areas will be removed during the excavation process.

• Excavation, which will begin at the uppermost part of Fields Brook and progress downstreamto prevent recontaminating areas that have been cleaned up. Thus, the tributaries will beremediated before excavating any downstream areas. Surface water will be controlled bydiverting the stream around the excavation. Outfalls from the individual industrial facilitiesmay be diverted in other ways. The excavated materials will be directly loaded onto dumptrucks and transported directly to the temporary storage areas.

Temporary storageareas will be developed for the two different treatments (thermal and stabilization). It isanticipated that the thermal treatment will be continuous and will take more than oneconstruction season (6 months) to complete, so the material must be stored to avoid freezing.

• Thermal treatment and stabilization, which will include thermally treating materialcontaminated with PCBs and stabilizing other material in accordance with the designated levelsshown in Table 3-1. Materials containing PCB levels above the cleanup objectives but belowthe threshold for thermal treatment will be disposed of in the containment cell withoutstabilization. Water generated from these operations and running off the storage areas will becollected in the detention basin and treated to meet the discharge criteria. The contractor mayuse this untreated water in the stabilization process.

• Preparation of a containment cell, which will be constructed in segments due to the length oftime required for thermal treatment. The first section will be constructed to accommodateonly the volume of material to be stabilized. It is anticipated that the material withcontamination levels below the threshold limit for thermal treatment can be treated within 6months; this section of the cell could then be capped. Since the thermal treatment is expectedto take more than a year, additional expansion to the cell could be completed as required toaccommodate this material. The cell will be designed and constructed to meet performancestandards as required by regulations.

The estimated hours and dollars presented on cost estimates will serve as the original budgets forthe project design. Budgets are broken down by work breakdown structure. The budgets willserve as a basis to monitor performance and to assess the impact of decisions on cost andschedule. The budgets will be revised by approved changes in scope. Actual costs areaccumulated monthly and compared with current budget figures to determine cost status.

9.2 ENGINEERING SCHEDULES

Schedule control comprises a significant segment of the project control system. This system willallow project management to keep abreast of progress, exercise control, and take correctiveactions to achieve project objectives within scheduled time frames.

A project master design schedule and supporting schedules will be developed based on initialwork plans and other supporting data. The project team will review the schedules, ensuring thatthey reflect the latest information concerning project scope, resources, and milestones. Aftertheir approval by project management, the master design schedule becomes the primary reportingtool for overall engineering progress.

The performance of work will be monitored, and progress will be measured according toachievement of specific discrete milestones and intermediate activities. The project schedules willbe updated to reflect the progress measurements and will be issued periodically to projectmanagement.

10.4 CONTENTS OF PROPOSAL PACKAGES

This task provides for preparation of the technical portions of the proposal packages as describedin Section 8.6.

The resulting technical packages will provide the basis for flexible construction bid packages thatutilize performance specifications and unit price items where possible and define optional workpossibilities. Preparation of the commercial portions of these bid packages (terms and conditions,bidder list, bidder selection, and bid evaluation) is not included.

11.0 FINAL DESIGN CONTINGENCIES

This work plan outlines a scope of work and schedule based on an 18-month schedule fordetailed design. However, there are a number of scheduled activities that must proceed inparallel with the remedial design.

• Design investigations (DI) will be completed and the results summarized in final form fordirect input. Further changes may require rework in design packages or inhibit completion ofpackages.

• The plans and specifications will make use of performance-based specifications for such thingsas waste treatment and solidification. Sufficient detail will be provided for bidding but thecontractor will be allowed to use unique equipment and knowledge to provide maximum costeffectiveness. Any requirements or investigations to provide detailed specifications will delaydesign completion.
