5 1.0 Introduction This Site Management Plan (SMP) establishes milestones associated with the performance of work and submittal of documents as stipulated in the Federal Facility Agreement (FFA) for Eielson Air Force Base (AFB) and fulfills the requirements of Paragraph 5.4 of the Institutional Control / Land Use Control (IC/LUC) Settlement Agreement that was signed 4/16/2013. The SMP addresses the following Operable Units (OU) and Installation Restoration Program (IRP) Source Areas at Eielson AFB: OU 1: ST20, ST48, ST49, SS50, SS51, and SS52 OU 2: ST10/SS14, ST11, ST18, ST19, LF05, SS31, SS62, and ST13/DP26 OU 3: DP44, WP45/SS57, ST56, SS61 OU 4: DP25, ST27, WP33, SS35, SS36, SS37, SS39/SS63, SS64, and ST58 OU 5: LF02, LF03/FT09, LF04, LF06, OU 6: WP38 Sitewide OU: SS67 The grouping of sites into OUs was based on the presence of similar contaminants and environmental characteristics. As a result, sites within OUs can be expected to have comparable goals and management requirements. Site investigations were conducted and led to development of a series of RODs which correspond to the OUs. These included: OU1: OU1B ROD and OU1 ROD OU2: OU2 ROD OU3, OU4, and OU5: OU3,4,5 ROD OU6: OU6 ROD Sitewide OU: Sitewide ROD In addition to the existing IRP sites, a number of sites are currently undergoing evaluation through the Source Evaluation Report (SER) process. These sites are managed under the FFA requirements until the sites are either closed or transferred to management under Alaska Department of Environmental Conservation (ADEC) Contaminated Sites regulations. 2.0 Work Accomplished in 2012 The Installation Wide Monitoring Program (IWMP) field effort included installation and development of 124 monitoring wells at 28 source areas, the Northern Boundary Wells area, and sampling of 210 monitoring wells (combination of new and existing). The IWMP represents a long term monitoring (LTM) program which is key for evaluating the protectiveness of remedies at the source areas and tracking individual site progress towards site closure goals. In addition to the monitoring well program, passive soil gas (PSG) sampling was conducted at 8 Page 1

6 source areas (ST18, SS36, WP38, DP44, SS50, SS51, SS52, ST56, and SS64) and involved installation of 260 samplers. The PSG results are expected to aid in placement of future monitoring wells. The Air Force initiated Conceptual Site Model (CSM) updates for source areas SS35, ST48 and ST20. The CSM updates are intended to provide additional detail on plume stability and contaminant of concern (COC) fate and transport.

7 Sediment sampling at SS67 in support of an RI SER Phase II investigation of SS86 (former AAA site) Removal of drums and debris from the pond area adjacent to SS35 Removal of piping and materials possibly associated with a skimmer system at ST11 as well as limited soil removal Data collected in 2011 and 2012 as part of the IWMP or other site investigation efforts was consistent with site expectations. There are no indications of any immediate threats to human health or the environment. No interim remedial actions, time critical removal actions, or non time critical removal actions are planned for the 2013 field season. 4.0 Schedule of Reports The Eielson AFB FFA defines Primary and Secondary documents as well as their associated review cycles and comment periods. As a result, only draft documents are shown in the milestone schedule since the dates of subsequent documents (e.g., Draft Final, Final) are dependent on whether the stakeholders request an extension in review duration and whether the Air Force requests an extension in developing responses to comments and revising the document. In addition to the FFA recognized document categories of Primary and Secondary, a third category,, has been added to the milestone schedule. s assigned to the category do not fall within the Eielson AFB FFA definitions of documents which would be either Primary or Secondary ( 20.3 & 20.4). For purposes of long term planning, documents assigned to the category are managed according to the review cycle for Secondary documents unless otherwise specified. NOTE: classification is established before a document is added to the SMP and requires concurrence from Air Force, EPA, and ADEC program managers. While Primary documents are always completed through production of an approved Final, Secondary and types of documents are only required to have a Draft with a formal response to regulator comments. These documents may never have corresponding stand alone final versions. The expectation is that any changes identified in the RTCs would be addressed in the Primary document which incorporates the Secondary document (i.e., RI RTCs addressed in RI/FS Draft). The FFA s connection of Secondary documents to Primary documents is clearly established for the CERCLA process leading up to a ROD. The connection for post ROD documents, however, not as clearly defined in the FFA. As a result, clarification was provided in the IC/LUC Settlement Agreement, Paragraph which states: Requirements and/or recommendations of the FYR and recommendations from the Annual Reports, where appropriate, will be incorporated into applicable decision documents, via an amendment and/or an Explanation of Significant Differences (ESD). Page 3

8 Further, the Air Force considers documents identified as Data Summaries, Technical Memorandum, or Conceptual Site Model Updates to be in support of evaluating source area progress towards achieving ROD goals. Findings and recommendations from these documents will also inform decision document action and, where appropriate, will lead to a ROD amendment and/or an ESD. The target document identified in the milestone schedule is where findings and recommendations from Secondary or categories of document will be addressed. It is either a Primary document or a document which follows the review cycle of a primary document.
