23. Sections 6.10.1.1 and 6.10.1.2 specify that the contractor shall perform monthly system optimization. Please provide a detailed scope of what is wanted/required for “system optimization”

System optimization is not part of this effort. See revised PWS.

24. Please clarify whether all of the required sampling equipment (i.e., generators, plumbing, vapor sampling devices, etc.) are present at the base and will be available to the new contractor?

No, the Contractor will need to provide sampling equipment.

25. Sections 6.10.1.1 and 6.10.1.2 specify that monthly site visits will be required to inspect SVE/VE systems. However, Section 4.1 of the OU-3 RA-O Work Plan discusses completing bi-monthly site visits during the winter/spring months due to higher condensate collection during those months. Please confirm the frequency of visits for this scope.

Monthly site visits are required as stated in the PWS. Bimonthly site visits are not required, but the contractor is free to visit the site more frequently if necessary to maintain the SVE systems in operational condition.

26. The PWS Section 6.10.1.1, Subsection D., specifies completion of quarterly RA-O reports for SD024 that “summarize O&M and monitoring results, including SVE system performance and vapor results, groundwater elevation maps, groundwater and soil vapor contaminant concentrations, and trends from previous quarters and years.” Section 4.4 of the OU-3 RAO Work Plan discusses that the 1st, 2nd, and 3rd quarter reports just summarize system performance data, with the 4th quarter report containing system performance data, along with sampling and analytical data. Please confirm that this is still the expectation, or will groundwater and bedrock vapor monitoring data be presented in quarterly reports as well?

Monitoring data will be presented in the quarterly RA-O reports as stated in the PWS.

27. Section 4.4 of the OU-3 RAO Work Plan discusses submittal of all analytical data to the IDEQ and EPA within 60 days of sample collection in spreadsheet format. Please confirm this is still a requirement?

Not a requirement of this contract. Analytical data will be summarized in the quarterly RA-O reports.

28. Please confirm the AF will provide escorts for any monitoring wells (to be sampled) located in the flight line red zone or any other secure areas on base.

Yes, escorts will be provided.

29. Schedule 8, cost schedule, contains major tasking by site and category of activity, and rolls up to an entire year for each of these breakdowns (base and option years 1 and 2). Please describe how invoicing is expected to be completed by the contractor?

Monthly invoicing should include work done at both sites.

30. Review of the PWS for this opportunity indicates RA-O and LTM are required (optimization of remedial systems and trends analysis), both of which are included in the AE13ES contract. Why isn’t this scope of work being managed via the AE13ES contract?

System optimization is not part of this effort. See revised PWS.

31. Several documents do not appear to be present on the AFCEC AR website. For instance, many documents refer to the “Final 2015 Annual Long-Term Monitoring Report for OU-3, Mountain Home Air Force Base (ARGO/LRS, 2016a), for reference to sampling frequency changes and miscellaneous work procedures. However, this document does not appear to be present in the AR. Additionally, there do not appear to be any documents for 2017 posted to the website. Please clarify if these documents are available for contractor use.

The 2017 reports will be posted soon, but probably not before contract award. The 2015 LTM reports have been added to the Administrative Record.

32. Section 6.1.0.1.1 of the PWS specifies that 25 regional base MWs will be sampled quarterly and reported in the quarterly RAO reports for SD024. However, it appears that the current optimized quarterly sampling of regional groundwater is a small subset of the entire base network. Please confirm that the scope includes sampling of the entire base network every quarter.

The contractor shall sample 25 specific wells as stated in the PWS, not the entire network.

33. Reference Section 6.10.1 of the PWS. How many monitoring wells require repairing and what nature are the repairs? What are the depths of these wells?

a. Examples of repairs to monitoring wells includes, but are not limited to: repairing or replacing well covers, bolts, gaskets, aboveground well casings, bollards, pumps, well caps and locks. It is not possible for the Government to know in advance which specific repairs and which wells will require repairs during the contract. Contractor needs to spell out its assumptions in its proposal.

b. As stated in the PWS, the average well depth is 420 feet bgs and the average depth to groundwater is 390 feet bgs.

34. Reference Section 6.10.1 of the PWS. How many monitoring wells require rehabilitation? What are the depths of these wells?

a. Assume 20% of the wells require rehabilitation annually for costing purposes.

b. As stated in the PWS, the average well depth is 420 feet bgs and the average depth to groundwater is 390 feet bgs.

35. Reference Section 6.10.1 of the PWS. How many monitoring wells require closing/abandonment? What are the depths of these wells?

The contractor will be provided all available files the Government has on contract award.

42. Will a container, such as a poly tank, be available to store the purge condensate and excess condensate from the moisture separate tanks at both sites or will the Contractor need to supply such containers?

Yes containers are currently on base for both SD024 and SS011 and will remain for contractor use. SS011 has a condensate drain line that leads to the sewer but requires repairs by the current contractor.

43. How is the condensate water purged from the vapor extraction lines and removed from the moisture separator tank from both sites disposed and at what quantities and frequency?

a. It is drained by gravity into a 5-gallon bucket and then disposed of the water in large poly tanks. SS011 has a condensate drain line that runs to the sanitary sewer through a pump but is currently not operational.

b. Approximately 1 gallon per month.

c. Monthly frequency.

44. Available RA-O reports indicate that several RGW monitoring wells do not have adequate recharge to sample through purging. Are PDBs an appropriate sampling method for these locations?

Yes, PDBs may be used if needed due to low water levels.

45. Section 6.10.1.1 C states, “Collect appropriate QA/QC vapor samples including but not limited to field duplicate and matrix spike/matrix spike duplicate (MS/MSD).” MS/MSD samples are typically not possible in soil vapor analysis. Is it acceptable to not include pricing for MS/MSDs for soil vapor samples in the cost proposal?

MS/MSD samples no longer required. See revised PWS.

46. Does SVE System optimization include compliance with air permits? Are copies of those permits available?
