Introduction
This report provides the design basis for the groundwater conveyance and discharge system being constructed for the groundwater remediation system at the former Baron-Blakeslee, Inc. (BBI) Solvent Recycling Facility (the Site) located in Portland, Oregon (Appendix A, Figure G-001). This remedial system is part of a groundwater remedial action being conducted by CH2M HILL on behalf of Honeywell International Inc. (Honeywell), which owns the BBI property. The location of the BBI property is shown in Figure 1. The property is a former solvent recycling facility, and constituents of concern (COCs) are volatile organic compounds (VOCs) of chlorinated solvents (1,1,1-trichloroethane [1,1,1-TCA], tetrachloroethene [PCE], and trichloroethene [TCE]) in soil and groundwater.
This remedial design has been completed to comply with a consent order entered into by the State of Oregon Department of Environmental Quality (DEQ) and Honeywell (DEQ Consent Order No. LQSR-NWR-08-09). The consent order requires Honeywell to design a groundwater remedy consistent with the Site’s Record of Decision (ROD) and in accordance with the Remedial Design/Remedial Action Scope of Work (SOW) in Attachment B of the consent order.
The selected groundwater remedy for the Site includes both a pump-and-treat system to remediate groundwater within the remedial action area, which is defined by maximum contaminant levels (MCLs), and groundwater circulation wells within the onsite source area. As outlined in the Remedial Design/Remedial Action Work Plan, Former Baron-Blakeslee, Inc., Solvent Recycling Facility Site, Portland, Oregon (CH2M HILL, 2009b), design and construction of the groundwater remedy will proceed in separate phases. This report covers the design and construction of the groundwater conveyance and discharge system for the pump-and-treat system.
This report is organized as follows:
• Section 1—Introduction describes the facility, purpose of the remedial action, and selected remedy.
• Section 2—Background presents background information, including the applicable remedial action objectives (RAOs), cleanup levels, the remedy selected in the ROD, and a summary of site geology and hydrogeology.
• Section 3—Groundwater Conveyance and Discharge System provides the design details for the water distribution systems.
• Section 4—Deliverables summarizes the deliverables associated with design of the groundwater conveyance and discharge system.
• Section 5—Permits and Access Agreements identifies the permits and access agreements required for the design work.
• Section 6—Schedule presents the schedule for completing each task.

SECTION 2.0
Background
This section presents the Site background information for the RAOs, a review of site-specific cleanup levels, a review of the selected remedy for the Site, and geology and hydrogeology.
2.1 Extraction System Remedial Action Objectives As described in the ROD, the groundwater RAOs for the Site are as follows:
• Prevent onsite occupational worker and offsite residential exposure to COCs in groundwater by direct contact, incidental ingestion, and inhalation that would result in an unacceptable excess lifetime cancer risk greater than 1 x 10-6 for individual chemicals, 1 x 10-5 cumulative risk for each pathway, and a hazard index greater than 1.
• Remediate the Unconsolidated Gravel Aquifer (UGA), Troutdale Gravel Aquifer (TGA), and Columbia River Sand Aquifer (CRSA) groundwater to levels protective of the potential future beneficial use as a domestic/municipal drinking water source.
• Control migration of contaminated groundwater containing COCs as necessary to protect the groundwater beneficial use.
2.2 Cleanup Levels According to the ROD, termination of the groundwater remediation system would be allowed by DEQ once the beneficial use of the aquifer is restored. This decision will be based on COCs meeting the United States Environmental Protection Agency MCLs in the UGA, TGA, and CRSA aquifers and complying with risk-based concentrations (RBCs) of drinking water at the nearest potential future supply well site C of the City of Portland Columbia South Shore Wellfield (DEQ, 2008).
2.3 Selected Remedy The selected groundwater remedy for the Site includes both a pump-and-treat system to remediate groundwater within the MCL remedial action area and groundwater circulation wells within the onsite source area. The locations of the extraction wells, MCL remedial action area, and modeled capture zone for the selected remedy are shown in Figure 2.
The pump-and-treat component of the remedy includes extracting groundwater from three offsite wells located along the approximate centerline of the groundwater plume. Groundwater removed from these extraction wells will be conveyed through a pipeline to a central treatment plant, where it will be treated by an air stripper to remove VOCs. The tentative location for the treatment plant is adjacent to TW-1, where Honeywell has an existing building on land leased from the Port of Portland. Treated water will then be discharged into the Columbia Slough. Depending on groundwater concentrations,

additional treatment of water—to remove other inorganics before discharge—may also be required to meet the requirements of the site Cleanup Discharge Authorization Permit (CDAP). Offgas treatment may also be required, depending on groundwater influent concentrations. Preliminary data collected during aquifer testing of the extraction wells indicate that inorganics removal and offgas treatment will not be necessary to meet permit requirements. Technical memorandums will be prepared presenting data in support of these conclusions and will be provided to DEQ for concurrence in summer 2011.
2.4 Site Geology and Hydrogeology A detailed discussion of the site geology and hydrogeology, including the stratigraphy and COC concentrations along the plume axis, is included in the Design Basis Report for Well Installation and Aquifer Testing, Former Baron-Blakeslee, Inc., Solvent Recycling Facility Site, Portland, Oregon (CH2M HILL, 2009a) and the Feasibility Study Report for the Former Baron-Blakeslee, Inc., Solvent Recycling Facility Site, 5920 NE 87th Avenue, Portland, Oregon (CH2M HILL, 2008). The area for VOC containment and remediation is within the UGA and TGA upgradient of the transition to the CRSA.

SECTION 3.0
Groundwater Conveyance and Discharge System
This section provides the design details for the groundwater conveyance and discharge system associated with the pump-and-treat system within the MCL remedial action area.
3.1 Design Objectives Design objectives for the well installation program are as follows:
• Outfall
− Minimize erosion along Columbia Slough bank − Minimize scouring in the slough channel − Minimize turbulence in the slough − Minimize impact to recreational users of the slough
• Conveyance piping
− Minimize leak potential
− Protect adjacent wetlands
− Size piping to accommodate various flow scenarios to allow for system adjustments to meet RAOs
− Allow independent monitoring of flow from each well
− Minimize potential vandalism
3.2 Conveyance Piping from Wells EW-1 and EW-2 Partially buried vaults will be installed over extraction wells EW-1 and EW-2, and the well heads will be modified as below grade completion according to Oregon Department of Water Resources guidance. The locations of the conveyance piping and associated electrical and instrumentation conduits from each well vault to the treatment building are shown in Appendix A, Figure C-100. Figure C-501 in Appendix A shows a cross section of the typical trench configuration.
Groundwater extracted from each well will be conveyed to the treatment building through separate buried double-wall piping. A sealed leak detection observation port will be installed at the low point of the pipeline alignment to allow periodic visual inspection for leakage from the carrier pipe. In addition, a small sump with float valve will be located within each well vault. Water accumulation within the sump will actuate the float valve,

which will in turn send a signal to the programmable logic controller (PLC) located at the treatment building to shut down the pump.
3.2.1 Pipe Size The piping is sized to maintain a minimum flow rate of 3 feet per second to minimize settling of solids in the pipe and a maximum flow rate of 8 feet per second to minimize head loss and potential scouring of the internal pipe wall. For smooth wall pipe, these velocity criteria result in the following range of flows:
Nominal Pipe Size (inches)
Minimum Flow (gpm)
Maximum Flow(gpm)
3 65 175
4 110 300
6 260 700
On the basis of current data, the predicted long-term flows range from about 80 gallons per minute (gpm) to 100 gpm for wells EW-1 and well EW-2. From among the design options shown in the table above, a 4-inch nominal diameter pipe is recommended for conveying water from both EW-1 and EW-2. Results from groundwater pumping tests are being evaluated to finalize design flow rates and associated pipe diameters.
Double-wall containment pipe will be used to convey water from each well vault to the treatment building. As indicated above, the recommended carrier pipe is 4-inch nominal diameter. The associated containment pipe will be approximately 8-inch diameter, a size that is typical for 4-inch, pre-manufactured, double-wall containment pipe.
3.2.2 Pipe Material Because of the presence of COCs (solvents) in the groundwater, even at low concentrations, material that can be used for the carrier piping is limited. Various materials were reviewed for this application, including polyvinyl chloride (PVC), high-density polyethylene (HDPE), fiberglass reinforced plastic (FRP), polyvinylidene fluoride (PVDF), and stainless steel (SST). PVC, HDPE, and FRP were found to be potentially acceptable, given the likely ranges of VOC concentrations.
Manufacturers for both PVC and HDPE double-containment piping systems reviewed the predicted concentrations and have stated their products are acceptable for this application. FRP was not considered for use because of its higher cost and higher risk for failure in a buried application. PVDF is acceptable for all concentrations of the chemicals, but the material cost, which would be approximately 10 to 20 times higher than those for PVC and HDPE, is considered cost-prohibitive. SST is acceptable for all concentrations, and single-wall 304 SST piping is planned for use in the vaults and treatment building.
HDPE material will be used for the conveyance piping.

PDX/111610001 3-3 ES032411184302PDX
3.2.3 Pipe Bedding Compacted sand or small rounded gravel (commonly referred to as pea gravel) will be placed as pipe bedding and pipe zone material under and around the pipe. Material from the trench excavation will be placed and compacted above the pipe zone to finish grade.
3.3 Well Vaults The design for the well vaults is shown in Figure C-502. A precast concrete vault will be installed at each extraction well location. The top of the vault will be approximately 1 foot above the adjacent ground surface. This design approach has been review and accepted by Oregon Department of Water Resources. The vault will be equipped with a watertight aluminum hatch with a bolt and gasket. The hatch will be design for H-20 wheel loading. Bollards will be installed around each vault for additional protection. Manifold piping and instrumentation within the vault will be included in the next phase of work.
3.4 Treated Water Discharge to Columbia Slough The design for the outfall is shown in Figure C-501. Treated water will be conveyed from the treatment building to the outfall diffuser in a buried HDPE pipe. The diffuser section will consist of a 32.5-foot-long section of perforated 12-inch-diameter HDPE pipe anchored on a narrow bench cut into the slough bank at elevation 18 (100-year flood elevation). Flow from the diffuser will travel downslope to the slough water surface over an anchored protective matting of concrete articulated block (Armorflex). Three rows of 0.75-inch-diameter pipe perforations will be oriented to direct flow downslope over the protective matting. Hydraulic calculations based on a total discharge flow of 400 gpm indicate discharge velocity through the diffuser ports on the order of 2 feet per second. This design approach has been reviewed and accepted by Multnomah County Drainage District.
3.5 Utility Clearance Before excavation, local utility companies will be contacted concerning the subsurface explorations. Utility checks will be performed by Utility Notification Center and by a private utility locator to ensure that the trench locations are at sufficient offset distances from utility locations. In addition, the upper 5 feet will be air-knifed and the cuttings will be inspected for evidence of utilities (uniform sand, caution tape, etc.) in the areas of identified underground utilities.
3.6 Management of Investigation-Derived Waste Upland soil at the Port of Portland property is uncontaminated based on samples collected during road construction activities in 2010. Soil that is not used for backfill in the pipeline trenches will be stockpiled, covered to prevent erosion, and used onsite for grading. Soils may be removed and disposed of offsite.
Soils excavated below the normal Slough water line will be stockpiled separately from upland soils. Characterization samples will be collected from the stockpiled soils at a

frequency of one sample per 100 cubic yards. Samples will be analyzed at an offsite laboratory for polychlorinated biphenyls, metals, and total petroleum hydrocarbons. Analytical results will be compared to DEQ direct contact screening values (Risk-Based Decision Making for the Remediation of Petroleum-Contaminated Sites, updated September 15, 2009). The most conservative values for the occupational, excavation worker and construction worker scenarios for each parameter will be used. Soils with concentrations below the screening levels may be reused onsite for upland regrading or disposed of offsite.
Water generated through dewatering or equipment decontamination activities will be containerized and then discharged to surface water under the existing discharge authorization letter from DEQ (July 15, 2009).

SECTION 5.0
Permits and Access Agreements
This section summarizes the applicable permitting requirements and access agreements required for the groundwater conveyance and discharge system construction.
5.1 Site Development Permit A Site Development Permit will be obtained from the City of Portland before mobilization.
5.2 Construction Stormwater Permit A project-wide 1200-C Construction Stormwater Permit has been obtained (File No. 100676). The permit specifies best management practices for stormwater management and stockpiled materials to prevent erosion.
5.3 Joint Permit Application On March 5, 2010, the U.S. Army Corps of Engineers (USACE) responded to a joint permit application granting permission to install an outfall below ordinary high water in the Columbia Slough.
5.4 Federal Aviation Administration Permit Honeywell has received a Federal Aviation Administration (FAA) permit for activities within the Portland International Airport flight path. The FAA regulates structure height within the flight path as it relates to routine flight and emergency situations.
5.5 Access Agreements Honeywell has secured a lease with the Port of Portland for the site.
5.6 Easements Honeywell is applying for a long-term easement from the Oregon Department of State Lands (DSL) for the discharge outfall structure. DSL is aware of the project from the Joint Permit Application process. No issues are expected.
