Free-Product Recovery

Former Naval Complex, Adak, Alaska

1.0 INTRODUCTION

The work involves recovery of free product at petroleum contaminated sites within Operable Unit A (OU A) on Adak Island at the Former Adak Naval Air Facility, Adak, Alaska. In addition, oil-absorbent booms shall be maintained at several locations on East Canal, West Canal and Sweeper Creek. Work shall involve removal of free-product from select wells on island using passive and manual means (hand bailing, absorbent socks, recovery canisters, etc.), maintenance of the oil-absorbent booms, monthly reports documenting the work, waste management, and preparation of an annual summary report.

The period of performance for this task is 608 days with free-product recovery and boom maintenance occurring for 12 months.

2.0 BACKGROUND

The Operable Unit-A (OU-A) Record of Decision (ROD) was executed in April 2000 (Reference 1). The ROD and the State-Adak Environmental Restoration Agreement (SAERA) (Reference 2) are the primary regulatory authority for petroleum sites on Adak. Sixty-two of the 128 petroleum sites in the ROD were removed via a 2003 ROD amendment (Reference 3). Fourteen of these sites were identified as having interim remedies (free-product recovery) but did not have final remedies; this has been documented in the Final Closure Report in Reference (4).

A decision document was executed in May 2005, which memorialized final remedies for 10 of the 14 sites (sites with no unacceptable risk) (Reference 5). The remaining four sites, NMCB, South of Runway 18-36, SWMU 62, and SWMU 17 decision documents were approved with all but SWMU 17 having free-product recovery as part of the final remedy (References 6, 7, 8, and 9).

Area 303 was defined after the OU A ROD was signed, and is characterized in a Focused Feasibility Study prepared by the Navy in 2011 (Reference 10). A decision document for Area 303 was approved in 2012 (Reference 11), which identifies the selected remedies of monitored natural attenuation, institutional controls, and free-phase product recovery.

In the summer of 2006, additional recovery/monitor wells were installed at NMCB, South of Runway 18-36 Area, and SWMU 62 sites. Recovery trenches were also installed at South of Runway 18-36 Area and SWMU 62. The Final Decision Documents for each site required that product recovery be continued until the technically practicable endpoint for free-product recovery is achieved, as defined in the OU-A ROD.

Recovery from the free-product collection/containment trenches shall continue until free product has been reduced to thicknesses less than 0.01 foot, or no sounding of the oil/water interface probe has been experienced for 1-year or more.

During the 2007 field season (October 2006 through September 2007) all three sites met the technically practical endpoint criteria for product recovery systems not dependent on water table depression, however, the collection/containment trenches did not meet the end point criteria.

Since 2007, NMCB, the South of Runway 18-36 Area, and Area 303 have met the technically practicable endpoint for free-product recovery and have been removed from the free-product recovery program. The Navy’s most recent findings and recommendations are summarized in the Final Remedial Action Summary Report Free Product Recovery dated December 19, 2017 is the baseline of this task order, Reference (12).

Soil removal actions were conducted at Building T451 and SWMU 62 by the Navy in 2011 and 2016 to address the petroleum seepage occurring into East Canal in the area of the (now former) recovery trench and recovery sumps (References 13 and 14). The removal action consisted of removal of the recovery trench, excavation of petroleum-contaminated soil, replacement with amended clean fill, and installation of seven monitoring wells.

3.0 SCOPE OBJECTIVE

The objective of this task order is to continue with the free-product recovery portion of the remedies presented in the Decision Documents (References 5, 6, 7, 8, 9 and 11), ROD and ROD Amendment (References 1 and 3) and the SAERA (Reference 2) for the subject site. This work shall be accomplished by removal of free-product from select wells on island using passive and manual means (hand bailing, absorbent socks, recovery canisters, etc.), maintaining oil-absorbent booms on affected waterways, inspecting wells for presence or thickness of free-product on groundwater, documenting activities in monthly reports, and completing a closure report that summarizes and documents the product recovery activities over the course of the year.

5.3 Mobilization/Demobilization

This task includes all labor, materials, and subcontractor costs for mobilizing and demobilizing to the site to complete free-product monitoring, fuel recovery and boom maintenance, and waste disposal activities.

5.4 Monitoring/Operation and Maintenance

The wells to be monitored will be identified during development of the O&M Plan prepared under Task 5.2. Approximately 35 well locations are monitored six times a year for depth to water and product thickness measurements. Free product from these wells is recovered using socks or canisters, following SOPs established in the O&M Plan prepared under Task 5.2.

The Navy will provide the list of well locations that is determined based on field observations during monthly O&M activities, recommendations following long term monitoring, and Alaska Department of Environmental Conservation (ADEC) requests. Typical depth to water is less than 20 feet. Wells are either 2 inch or 4 inch in diameter. Recommendations for changes to well locations shall be made to the Navy as appropriate, and the Navy will provide technical direction as to which wells are to be monitored. If monitoring of more than 35 wells is required for any field event, additional SLINs will be awarded.

Based on monthly or annual monitoring findings and ADEC requests, the wells to be monitored may vary. The number of wells anticipated to be added should not increase the level of effort substantially and may be balanced by reductions in wells monitored based on lack of free-product.

5.4.1 The contractor shall conduct monitoring on ad-hoc wells as necessary on wells that are requested by ADEC or NAVFAC Northwest. Such monitoring may include direct measurement of water quality parameters (such as dissolved oxygen, oxidation reduction potential, pH, temperature or conductivity) to demonstrate remedy performance.
