Remediation & Site Characterization - Kotzebue, AK

Amendment 0001 Questions & Answers

1. Can previous site characterization reports be provided?

The previous BIA report is attached. Historic reports are available from DEC or on their website.

2. Please confirm the additional delineation to be performed as part of this project is limited to the 16 locations identified in the PWS.

Up to 16 test pits and/or soil borings are authorized.

3. Are the Work Plan and Sampling and Analysis Plan intended to be separate documents, or may they be combined into a single document?

They may be combined in a single document.

4. The PWS identifies previous damage/loss of monitoring wells that may require repair or replacement. How many wells should the contractor assume require repair or replacement?

Unknown. During previous projects, some contractors were not prepared to repair any, resulting in lost sampling opportunities. In the past damaged or lost well points have been 0-3.

5. The PWS mentions evaluation of multi-season, tide-influenced groundwater dynamics.

Can BIA clarify this aspect and state whether groundwater monitoring is limited to a single event or multiple events, and if multiple events, how many?

For this contract groundwater monitoring consists of a single event. Groundwater dynamics are mentioned for contractor awareness.

6. Task 3 requires product recovery activities, if applicable, until no sheen/product is detected.

Since product recovery could continue for years, can BIA clarify the requirements for product recovery activities that should be included in the proposal?

During well monitoring and sampling free product could potentially be encountered. In that case DEC may request some product recovery action, such as installing a sorbent boom or similar effort prior to departure. Any further efforts would occur under a separate contract.

7. How many wells should contractors assume will require product recovery activities?

Previously, free product has been detected in 2 of the 16 monitoring wells.

8. For IDW soils requiring off-site disposal, can the soils be transported to and managed at the KIC landfarm where other contaminated soils are currently being managed?

The Alaska DEC is the regulatory authority responsible for IDW requirements.

9. Are there established rates for soil treatment at the KIC landfarm?

This question is for KIC.

10. Are there page limits or specific instructions for the technical response?

No page limit. Quotation contents are listed in the RFQ beginning on page 14 of 16.

https://sam.gov/workspace/contract/opp/e974675b4716496d9d346c4f7f77efe8/view

11. Please make available relevant historical documentation, particularly the Kotzebue 2024- 2025 Site Characterization Report.

Attached.

12. In absence of historical condition data, it is assumed that 2 of the 16 groundwater monitoring wells will require replacement.

At the close of the previous effort, one well was known to be obstructed (MW06). In the past damaged or lost well points have been 0-3.

13. Analyses are assumed at AK101 (GRO), AK102/103 (DRO/RRO), SW8260 (VOC), and SW8270-SIM (PAH) for both soil and groundwater.

Soil and groundwater samples will be analyzed for DRO, PAHs and VOCs following Alaska DEC regulations and guidance.

14. Assume 2 soil samples per test pit/soil boring targeting (1) highest PID in the vadose zone and (2) the interval at the soil-water interface.

Soil and groundwater samples will be collected following Alaska DEC regulations and guidance.

15. It is assumed that duplicate samples will be collected at 10% and MS/MSD at 5% frequencies for each analysis and medium.

Soil and groundwater samples will be collected following Alaska DEC regulations and guidance.
