| No. |
| 9. Do the existing wells contain dedicated equipment or tubing? If so, please specify the type. |
| No. |
| 10. Are there any wells in restricted access areas? Are the wells easily accessible (within several feet) by a standard pickup truck? Are the wells located on pavement, grass, or dirt? |
| There is controlled access to the landfills but the areas are not “restricted i.e. needing special security access or badges”. |
All wells are readily accessible.
The wells are completed on dirt with grass.
| 11. How much lead time does the Base require of the Contractor to obtain access? |
| 2 to 4 weeks |
| 12. When were the existing wells sampled last? Do they need to be redeveloped prior to sampling? |

| 14. Please provide a map showing the locations of the existing and proposed well locations? |
| The contractor will be responsible for reviewing historical data to identify optimum well locations. |
A map of existing wells will be made available upon request to angelica.alcayde@us.af.mil and linda.cavazos@us.af.mil.
| 15. If one or more of the new wells are found to contain constituents of concern above action levels such that further delineation may be required, will the Air Force still require a Proposed Plan and Record of Decision to be filed under this Task Order? |
| The landfills area has been extensively investigated. |
Additional delineation is not part of this project.
| 16. Section 6.10.6 of the PWS suggests that remedial and/or monitoring systems may be present that will require monitoring, adjustment, and/or repair. Please describe what systems are present, where they are located, and the typical repairs and/or adjustments that have been most recently performed. How often are these systems to be monitored under this TO (weekly, monthly, semi-annually, other)? |
| There are no remedial systems requiring maintenance associated with the four (4) landfills. |
| 17. Please provide copies of the existing WP, HSP, and SAP referenced in Section 4.11 of the PWS that require updating. |
| See response to question 3. |
| 18. Please clarify if only a WP in the QPP is required or if a UFP-QAPP is also required? Section 3.5.1 of the PWS (first paragraph, last sentence), Section 4.11.3 (last sentence) and Section 4.11.4 (first paragraph, last sentence) all refer to incorporation of minimum QA/QC in a UFP-QAPP. The middle two paragraphs of Section 4.11.4 have four references to the “WP and UFP-QAPP”, but elsewhere there is no specific requirement for development of a UFP-QAPP, only a WP in the QPP. |
| An UFP-QAPP has already been developed for Maxwell AFB. |

| See response to question 13. |
| 20. Are there monitoring wells that purge to dryness or take an excessive amount of time to low-flow purge before sampling? If so, how many? |
| No. |
| 21. Do any of the monitoring wells have dedicated sampling systems? If so, how many? |
| No |
| 22. A site visit would be very beneficial in developing the most responsive bid. Can the government provide an opportunity for a site visit to the Landfills included within this solicitation? What should a bidder do to coordinate a site visit? |
| A site visit is not anticipated for this effort. |
| 23. Can the Government please summarize the data goals for the installation of the 9 new groundwater monitoring wells? If the site(s) are entering a Proposed Plan, it would be assumed that nature and extent delineation activities are complete. |
| The nature and extents of contamination have been delineated. |
The purpose of this project is to re-align four landfills (LF003, LF004, LF005, and LF006) to the proper regulatory context, ADEM 335-13, Solid Waste Rules. Currently, the landfills are monitored as part of the OU-1 groundwater plume, as established in the 2002 ROD, but are not part of the contaminant plume nor are they contributory to the plume. Monitoring at the landfills currently includes only VOCs. Sampling for ADEM 335-13 landfill parameters has not been conducted since 2004.
The re-alignment is to be accomplished by the installation of additional monitoring wells as noted, semi-annual sampling for two (2) years to determine remaining contaminants and concentrations, preparation of a Proposed Plan documenting LTM with LUCs as the selected remedy, and preparation of the ROD to remove the landfills from the OU-1 ROD.
| 24. Can the government provide any additional well-specific information that would assist potential bidders in development of a level of effort for well sampling? Do any existing wells have dedicated sampling equipment? Do any wells demonstrate poor groundwater production that impacts sampling time? |
| Well inventory and construction specifications will be made available upon request to angelica.alcayde@us.af.mil and linda.cavazos@us.af.mil. |
All new wells shall be ASTM Type II.
There is no existing sampling equipment.
There are no wells that demonstrate poor production.
| 25. Can the Government direct potential bidders to a Feasibility Study, or similar document, that evaluates potential remedial alternatives for carrying forward in the Proposed Plan? Or, is the ARBCA Evaluation Report, Landfills 4, 5, & 6 (LF-004, LF-005, & LF-006), the only report to support remedy identification and selection? |
| Yes, the ARBCA Evaluation Report is the only document supporting the selected remedy. |
The selected remedy going forward is LTM with LUCs. The Proposed Plan and ROD will document this remedy.
| 26. The solicitation includes requirements for the Contractor to provide many O & M related services that are not described or specified to a degree that would allow costing. For example, PWS Section 6.6 states that the Contractor shall operate, maintain, and perform services in support of hazardous waste operations; Section 6.10.1 indicates sampling of very many different types of media shall be conducted, and Section 6.10.6 indicates that the Contractor shall monitor and repair remedial equipment. This is not an exhaustive list. Can the government clarify the scope of services to be provided under this Contract? |
| Section 6.10.6 has been deleted from the Performance Work Statement (PWS). See revised PWS dated 16 May 2018 which is attached. |
There are no O&M requirements at this time.
Based on the types of waste known to have been disposed in the landfills, the wastes are not considered to be hazardous.
Groundwater is the only medium of concern and will be sampled in accordance with ADEM 335-13, Solid Waste Rules.
| 27. Given the tasks required under the PWS, the proposed 12-month period of performance seems insufficient. Will any consideration be given to extending the PoP to 18 months? |
| See response to question #2. |
| 28. In section 6.10.5, heading C (page 18 of 22) of the PWS, it is our understanding that one semi-annual report covering all four landfills is to be submitted for each of the 2 sampling events, for a total of 2 SA reports over the course of the contract. Please confirm if this is correct. |
| There will be one report that includes the four landfills per semi-annual event. Two years of semi-annual sampling are proposed, therefore a total of four (4) Semi-annual Reports are required. |
| 29. As noted in the PWS, FT002 is co-located with LF003. Is the Proposed Plan (PP) and Record of Decision (ROD) also required to also address FT002? |
| No. FT002 is being addressed under a separate contract. |
| 30. Is there a document available to summarize the current remedial status at LF003, LF004, LF005, and LF006? This information will assist in identifying the scope for the PP and ROD. |
| AR#895 – Landfill ARBCA Evaluation. |
The PP and ROD will be prepared to remove the landfills from the OU-1 ROD (2002, AR#9004) and place them in the proper regulatory context.

| See response to question 22. |
| 50. Par 1.1 Introduction refers to AR#1129 for an overview of all four landfills. There is no overview of Landfills 4, 5 and 6 in AR #1129. AR #1129 only provides information for Landfill 3. Please provide the AR# for overviews of Landfills 4, 5 and 6. |
| AR#1129 is the Data Gap Analysis Report and contains information on LF003. |
AR#895 is the Landfill ARBCA Evaluation Report and provides the most recent investigation results at the landfills.
Both documents will be made available upon request to angelica.alcayde@us.af.mil and linda.cavazos@us.af.mil.
| 51. The PWS title defines LTM as Long Term Management, but the introduction section describes LTM as Long Term Monitoring. Long-term management is conducted after achieving Response Complete, however the PWS only includes documentation through a Record of Decision (ROD) and does not appear to include implementation of the remedy. Please clarify. |
| The PWS has been revised to change “long term management” to “long term monitoring”. |
The selected remedy is long-term monitoring with LUCs.
The purpose of this project is to re-align four landfills (LF003, LF004, LF005, and LF006) to the proper regulatory context, ADEM 335-13, Solid Waste Rules. Currently, the landfills are monitored as part of the OU-1 groundwater plume, as established in the 2002 ROD, but are not part of the contaminant plume nor are they contributory to the plume.

Annual monitoring will continue during the PP and ROD preparation for the duration of the POP
The PoP will be extended from 12 months to 30 months
| 52. According to the Admin Record, the monitoring wells that were within the footprint of LF-4, 5, and 6 were abandoned during landfill cover reshaping and drainage improvement project a few years ago. Following the reshaping and establishment of the new landfill cover for LF-4, 5, and 6, Maxwell did not allow installation of new monitoring wells through the cover to maintain the integrity and prevent precipitation infiltration. Are new wells to be established within the footprint of the landfills? |
| The new wells are to be installed outside the footprint of the soil cover. |
Refer to AR# 895 for information on the interior components of the landfills which will be made available upon request to angelica.alcayde@us.af.mil and linda.cavazos@us.af.mil.
| 53. Does Government anticipate no further action of the landfills since no feasibility study has been included as a submittal prior to the Proposed Plan? |
| No. The selected remedy is LTM with LUCs. |
The purpose of this project is to re-align four landfills (LF003, LF004, LF005, and LF006) to the proper regulatory context, ADEM 335-13, Solid Waste Rules.
