PORT OF SEATTLE MEMORANDUM COMMISSION AGENDA Item No. 6b Date of Meeting May 24, 2011 DATE: May 17, 2011 TO: Tay Yoshitani, Chief Executive Officer FROM: Stephanie Jones Stebbins, Director, Seaport Environmental & Planning Programs Kathy Bahnick, Seaport Environmental Programs Manager Roy Kuroiwa, Senior Environmental Program Manager Susan Ridgley, Senior Port Counsel SUBJECT: Administrative Settlement Agreement and Order on Consent (ASAOC) for Removal Action Implementation at Terminal 117, an Early Action Area (EAA) for the Lower Duwamish Waterway (LDW) Superfund Amount of This Request: $28,183,000 Source of Funds: Tax Levy plus Cost Recovery (does not include cost recoveries) from other funds, including grants, partner reimbursement, and insurance Est. State and Local Taxes: $898,000 Est. Jobs Generated: N/A Total Project Cost: $32,835,000 (Est. Net Costs to Port: $ up to 17,926,000) cs ACTION REQUESTED: Request Commission authorization for the Chief Executive Officer to execute an Administrative Settlement Agreement and Order on Consent (ASAOC) with the Environmental Protection Agency (EPA) and the City of Seattle for the Removal Action Implementation at Terminal 117, an Early Action Area (EAA) for the Lower Duwamish Waterway (LDW) Superfund. SYNOPSIS: For over ten years, the EPA has been investigating contamination in the Lower Duwamish Waterway Superfund Site. Terminal 117, which is contaminated from polychlorinated biphenyls (PCBs) caused by industrial uses dating from the years before the Port owned the property, was one of the sites on the Duwamish Waterway identified by the EPA as an "Early Action Area" that needed to be addressed through cleanup actions prior to a final EPA determination of cleanup requirements for the LDW as a whole. The Port performed a cleanup of T-117 in 1999, but additional PCB contamination was discovered on the uplands in 2005/2006. In response to community input, the Port agreed to clean up the property to meet unrestricted (residential) standards in 2007. The current EPA order under review and evaluation would likely be the last cleanup obligation at T-117 required by the Port. The total estimated project cost of this cleanup is $32,835,000 with a net cost to the Port of up to $17,926,000 after other anticipated cost recovery COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer May 17, 2011 Page 2 of 8 funds are factored in. The Commission authorized this funding on December 7, 2010 , as part of the five-year (2011 2015) spending plan for the 2011 Environmental Remediation Liability Program. The cleanup is being funded by the tax levy and any cost recoveries the Port receives, such as grants, insurance and partner reimbursements. The T-117 removal action work consists of the Remedial Design and Removal Action (RA/RD) activities associated with the cleanup design, construction, and (if necessary) long-term maintenance and monitoring of the T-117 Upland, Sediment, and Adjacent City Streets. This work is further detailed in the ASAOC"s Statement of Work (SOW) and EPA"s record of decision contained in its September 30, 2010, Action Memorandum. The T-117 Early Action Area (EAA) project consists of three geographic subareas: the Sediments; the Port-owned T-117 Uplands; and the City"s Adjacent Streets and Yards. The Port is taking the lead in two subareas the Sediments and T-117 Uplands with an estimated total cost of $28,183,000. This estim ated cost does not include anticipated cost recovery opportunities, such as Washington State Department of Ecology (Ecology) grants and the City"s payment of its share pursuant to a Settlement Agreement. The City is paying all costs associated with the third subarea the T-117 Adjacent Streets and Yards. As noted above, most of the Port"s share of estimated costs were included in the five-year Environmental Remediation Liability authorization, as approved by Commission on December 7, 2010. On June 3, 2010, the Port and City jointly submitted the T-117 Engineering Evaluation/Cost Analysis report (EE/CA) to EPA . The EE/CA defined options for cleanup of the T -117 site. EPA thereafter selected a Removal Action Alternative; its decision was memorialized in the Action Memorandum dated September 30, 2010. EPA then issued to the Port and the City a draft ASAOC for Removal Action Implementation and attached Statement of Work (SOW), which is the subject of this memo. Port staff have reviewed and negotiated the content of these documents and recommend that the Commission authorize the CEO to sign the final order. BACKGROUND: For over ten years, EPA has been investigating sediment contamination in the Lower Duwamish Waterway (LDW) Superfund Site. In 2003, EPA identified a number of localized contaminated areas ("Early Action Areas" or "EAAs" that needed to be addressed through cleanup actions, prior to a final EPA determination of cleanup requirements for the LDW as a whole. One such location is the LDW sediments and adjoining bank area in the vicinity of the Port property at Terminal 117, referred to as the "T-117Upland and Sediment Site." The property has also been referred to in earlier Commission actions as "the Malarkey Asphalt Site." Contamination in the T-117 area is primarily from PCBs, which were used widely for decades, including for transformers and other electric equipment, before their manufacture and use was banned in the United States in 1978. An asphalt shingle plant operated on the upland property for many decades, and, for a period of time in the 1970s, that facility used waste transformer oil as fuel. Seattle City Light appears to have been the source of a significant volume of this waste oil, which was likely tainted with PCBs. Asphalt plant mishandling of waste transformer oil is the most likely source for the majority of the PCB contamination in the vicinity of T-117. COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer May 17, 2011 Page 3 of 8 In 1999, the Port, under EPA supervision, carried out what was believed at the time to be a final cleanup of the upland T-117 property. In 2000, the Port completed its purchase of the property from Marlarkey. Following EPA"s designation of the T-117 sediment site as an "Early Action Area," the Port and the City entered into a Memorandum of Agreement in May 2003 to jointly fund the investigation and remediation of contamination within the sediments and in the adjoining bank area. In December 2005, the Port, the City, and the EPA entered into an "Administrative Settlement Agreement and Order on Consent (ASAOC) for the T-117 Early Action Area Removal Action" to perform the work in the sediment and bank areas only. The Agreement required the Port and the City to clean up sediments, intertidal mudflats, bank, and a limited portion of the adjacent uplands. During the investigation of the bank area, significant contamination above action levels was discovered on the T-117 uplands. In 2005, EPA and the Port agreed to pursue additional investigation of the level and extent of the contamination on the T-117 uplands through an ASAOC for the Upland Investigation. This investigation did identify additional upland areas that required remedial actions. Based on this subsequent upland investigation, in 2007 the SOW of the 2005 ASAOC was amended, and the T-117 cleanup site formally expanded to include three distinct subareas: the Sediments, T-117 Uplands, and Adjacent Streets. In addition, EPA issued a letter (April 12, 2007) directing the Port to clean up the former industrial property to meet unrestricted (e.g., residential) cleanup standards. In addition, the 2005/2006 upland investigations also discovered elevated PCB concentrations, prompting EPA to issue the 2006 ASAOC for Time Critical Removal Action (TCRA, e.g., interim removal action). The TCRA was issued to quickly remove upland soil that contained very high concentrations of PCBs in order to: a) prevent human exposure and b) remove contaminant sources that are readily available to the waterway. This work was successfully completed in the winter of 2006. In 2008, the Commission authorized a settlement agreement with Malarkey and the City of Seattle (among others). The relevant portion of the settlement agreement is that future costs were allocated between the City and the Port as follows: the City would pay 100 percent of the costs of the Adjacent Streets and yards, and the Port and the City would share the costs of the Sediments and Uplands, with the Port paying 60 percent of the costs and the City paying 40 percent. The Port also received $9.8 million as part of the Malarkey/City settlement. The basis of the final design, cleanup, and long-term monitoring and maintenance for the T-117 EAA Remedial Design and Remedial Action was presented in the T-117 Sediment, Uplands, and Adjacent Streets EE/CA, dated June 3, 2010. The final EE/CA was approved by EPA with the issuance of the EPA Action Memorandum, dated September 30, 2010. The EPA Action Memo selected Alternative 2 in the EE/CA. Alternative 2 is described as a comprehensive Upland (soil) and Sediment Removal and Backfilling (no capping) that meets unrestricted (e.g., residential) cleanup standards. The alternative provides a comprehensive soil and sediment cleanup approach that requires no significant long-term monitoring or administrative controls, regardless of the ultimate land use (e.g., industrial/commercial, residential, or other). COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer May 17, 2011 Page 4 of 8 PROJECT JUSTIFICATION: The overall goal of the T-117 cleanup is to significantly reduce or eliminate the exposure of ecological and human receptors to sediment and soil contamination and thereby reduce or eliminate adverse effects on resources in the T-117 EAA. The Port has signed previous EPA orders that required that the Port perform T-117 assessment, cleanup evaluation, and past cleanup actions (e.g., the Time-Critical Removal Action [TCRA]). The current EPA order under review and evaluation would likely be the last cleanup obligation required by the Port. PROJECT STATEMENT AND OBJECTIVES: Project Statement: Finalize and implement the EPA-issued ASAOC that requires the Port and City to complete the remedial design and cleanup construction, and (if necessary) long-term monitoring and maintenance of the sediment, upland, and adjacent streets of the T-117 EAA, as detailed in the SOW. This consists of the detailed analysis, design, and construction implementation of the selected Alternative No. 2, as presented in the Final EE/CA and EPA"s Action Memorandum, dated September 30, 2010. Project Objectives: Comply with and fulfill the requirements of the EPA"s ASAOC and SOW. Complete the SOW tasks in accordance with the project schedule and timeline. These project goals and objectives align with Seaport"s goal of environmental stewardship, as described further below. PROJECT SCOPE OF WORK AND SCHEDULE: Scope of Work: The scope of work that will be performed by the Port (and the City) is defined by the 2011 ASAOC as follows: 1. Respondents shall perform, at a minimum, all actions necessary to implement the Statement of Work (SOW); and 2. The actions to be implemented generally include, but are not limited to, the implementation of the Action Memorandum for T-117 EAA dated September 30, 2010, as set forth in the SOW. The scope presented in the SOW requires Remedial Design and associated documents. This includes producing the Design Report, 15/30/60/90/100% Design Documents, and supporting deliverables such as Community Health and Safety and Compliance Monitoring Plan. The SOW also requires Removal Action (i.e., cleanup construction) and associated documents. This includes implementation of the physical cleanup itself, and production of a Construction Documentation Report and As-Built plans. A Long-Term Monitoring & Maintenance Plan is required by the SOW; however, no time frame for monitoring has been provided; therefore, one year following completion of Removal Action is assumed for this project.

Of the total, $1.645 million will be used for non-grant eligible clean-up related costs. Note 2: Port is also seeking recovery from insurance. Cost Estimate Associated with this Agreed Order: The actual cost for the cleanup design and implementation, including compliance monitoring, is expected to vary, depending on actual site conditions, labor and material costs at the time of construction, and any changed conditions or requirements established by the oversight agencies (EPA and Ecology). However, based on the final 2010 EE/CA and the findings of the EPA Action Memo, the total estimated costs for this work will be approximately $28,183,000. Source of Funds: The cost to implement the T-117 Remedial Design and Removal Action were included in the Commission"s 2011 Environmental Remediation Liability spending authorization, approved on December 7, 2010, for 2011 costs. The five-year forecast (April 2011 through June 2015) for T-117 Remedial Design/Removal Action, prior to any cost recovery from outside parties, ranges from $28,000,000 through $30,000,000. Any additional clean-up costs that may be required as the project COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer May 17, 2011 Page 6 of 8 moves forward will be recorded as a liability and a non-operating expense in accordance with Port Policy AC-9. These amounts will be reported annually to the Commission via routine Environmental Remediation Liability reports and spending authorization requests. The Port"stax levy will pay the costs for the environmental cleanup project that are not ultimately covered by cost-sharing agreements, insurance, grants, or other cost recovery sources. Under an existing cost sharing settlement agreement, the City of Seattle will pay 40 percent of the contracted and agency oversight costs (approximately $11,292,000). In addition, Port staff continues to pursue grant funding from Ecology for the design and construction work. Finally, another source of expected future funding includes expected reimbursements from the Port"s insurance. Net Costs to Port: The cost summary table above presents a breakdown of all the paid, committed, and/or anticipated total costs and recoveries associated with the T-117 cleanup, including both prior and future design and cleanup activities. As shown, the total (start to finish) Port cost is approximately $32,835,000. The total received, requested, and anticipated cost recovery funds (not including insurance or uncommitted grant requests) is approximately $14,910,000. Therefore, the net cost to the Port to complete the T-117 EAA cleanup work is expected to be up to approximately $17,926,000. ECONOMIC IMPACTS AND BUSINESS PLAN OBJECTIVES: In addition to the numerous environmental and public health benefits, this cleanup action will enhance future use of T-117 by reducing or likely eliminating the possibility that future cleanup orders or actions will disrupt future site use, including site restoration, tenant operations, or future owner"s activities. Thecompletion of this Removal Action will also open up alternative land use considerations for the Port, including the potential for creating habitat as mitigation to offset the Port"s Natural Resource Damage Assessment liability. STRATEGIC OBJECTIVES: This project will achieve the strategic objective of accomplishing cleanup of the Port"s property, as required by state and federal agencies. Obtain the maximum cost recovery for design and cleanup expenses from state grants, insurance, and other responsible parties such as the City of Seattle. Provide community outreach and participation during all aspects of the cleanup design and implementation. Evaluate opportunities to enhance local job creation and resource utilization. Evaluate and consider sustainable and "green" remediation and construction technologies and practices. ENVIRONMENTAL SUSTAINABILITY/COMMUNITY BENEFITS: Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), EPA reviews cleanup projects to ensure that they meet the substantive requirements of federal and state laws and regulations that are applicable or relevant and appropriate. Elimination of unacceptable levels of risk to human health and the environment caused by the presence of contaminants in soil, groundwater, and sediment is not only required by state and federal law, but it COMMISSION AGENDA Tay Yoshitani, Chief Executive Officer May 17, 2011 Page 7 of 8 is the hallmark of responsible environmental stewardship, from the perspectives of both the surrounding communities and the customers that we serve. TRIPLE BOTTOM LINE: State and federal laws require elimination of unacceptable levels of environmental risk caused by the presence of contaminants in soil, groundwater, and sediment. From the perspective of the surrounding communities and the customers that we serve, the Port"s participation in site remediation is the hallmark of responsible environmental stewardship. ALTERNATIVES CONSIDERED and THEIR IMPLICATIONS: Refuse to enter into EPA"s ASAOC. If the Port decides not to enter into the ASAOC, EPA could issue a unilateral enforcement order under CERCLA that would require the Port to conduct the cleanup, and in addition possibly impose other financial fines and penalties. Alternatively, if EPA simply looked to the City to pay all costs, the City might bring a claim against the Port, based on the terms of our Settlement Agreement. Agree to enter into EPA's Agreed Order. Port staff has reviewed the terms of the ASAOC and SOW and have determined that the required work aligns with the work described in the Port"s EE/CA and EPA"s Action Memorandum. Staff believes that the Agreed Order"s terms would provide more efficient and cost-effective cleanup procedures than would be imposed through a unilateral order. This is the recommended alternative.
