Questions & Answers

Q1. Site Visit: Does the Government intend to conduct or permit a site visit prior to the quotation deadline? If so, please provide the available date, time, meeting location, and applicable facility-access requirements. Given that the requirement involves excavation, equipment access, temporary staging of contaminated material, backfill, and site restoration, a site visit would assist offerors in developing accurate and competitive pricing.

A1. Yes, the solicitation was amended and a site visit was provided on 2 September 2026 at 0900.

Q2. Exact Remediation Location: Could the Government provide the exact location of the contaminated area within Sheppard AFB, including any available site map, coordinates, photographs, approximate dimensions, or other information identifying the work area?

A2. The remediation will occur on Installation property, but outside the Installation perimeter fence on the northeast corner of the intersection of 9th Ave and Burkburnett Road.

Q3. Site Photographs: If a site visit cannot be accommodated prior to quotation submission, could the Government provide photographs showing the remediation area, surrounding vegetation, fencing, pavement, access points, nearby structures, and available equipment or staging areas?

A3. Please refer to Question/Answer 1.

Q4. Source of POL Contamination: Does the Government know the specific petroleum, oil, or lubricant associated with the release, such as diesel, gasoline, JP-8, hydraulic fluid, lubricating oil, or another petroleum product? If known, please identify the product and approximate date and/or cause of the release.

A4. Diesel

Q5. Existing Environmental Data: Does the Government have any existing laboratory reports, soil sampling results, spill reports, field-screening data, photographs, or other environmental information associated with this release? If so, could those documents be provided to offerors for use in developing their quotations?

A5. No sampling of the contaminated soil has been conducted. The contamination occurred from a tractor trailer accident that punctured the diesel tank. Approximately 45 gallons spilled from the tank with some recovered using spill containments.

Q6. Basis of the Eight-Cubic-Yard Estimate: The Statement of Work identifies approximately eight (8) cubic yards of POL-contaminated soil/grass. Could the Government provide the approximate length, width, and anticipated depth used to develop this estimate? Additionally, please confirm whether the eight cubic yards represents in-place excavation volume or estimated loose/disposal volume.

A6. The anticipated excavation area is 17’ x 10’. However, the depth is unknown. The 8 CY is the anticipated loose/disposal volume.

Q7. Contamination Beyond the Estimated Eight Cubic Yards: The Statement of Work requires excavation to continue to the extent of confirmed absence of contamination.

If the actual contaminated area extends beyond the Government’s estimated eight cubic yards, how should offerors account for the additional excavation, sampling, containerization, transportation, disposal, backfill, and restoration? Would quantities exceeding the estimated eight cubic yards be addressed through a contract modification or equitable adjustment, or should offerors include the entire unknown quantity risk within their firm-fixed-price quotation?

A7. Quote should include the estimated eight cubic yards. Contractor will need to submit a Request for Information (RFI) for unforeseen site condition to initiate a mod if needed for work required beyond the initial estimated area of contamination.

Q8. Unit Pricing for Additional Quantities: Would the Government consider allowing offerors to provide a base price for the estimated eight cubic yards together with unit pricing for additional contaminated soil, laboratory samples, transportation/disposal, backfill, and restoration if actual quantities exceed the Government’s estimate? This clarification would allow offerors to competitively price the known requirement without incorporating excessive contingency for unknown subsurface conditions.

A8. Yes, the Contractor is allowed to add line items to their quote and the Government will accept quotes that include both known and unknown quantities for evaluation. Contractor is required to designate which line items are optional. All quotes will be evaluated on a competitive basis utilizing best value as described in the solicitation.

Q9. Final Cleanup / Acceptance Standard: Please clarify the analytical standard that will determine when excavation may stop and remediation will be considered complete.

The Statement of Work references both clearance samples matching background conditions and the TCEQ TRRP Table 5 cleanup levels. Should final acceptance be based upon:

a. Background concentrations; b. Applicable TCEQ Tier 1 Commercial/Industrial PCLs; or c.

The more stringent of the two?

A9. TPH levels on the TCEQ TRRP Table 5

Q10. Applicable TCEQ TRRP Table 5 Criteria: Please confirm which TCEQ TRRP Table 5 source-area criteria apply to this project. Should offerors use the 0.5-acre source-area criteria, 30-acre source-area criteria, or another applicable criterion when evaluating the required cleanup levels?

A10. 0.5 acre source area criteria

Q11. Applicable TPH Cleanup Levels: Please confirm which TPH fractions and corresponding cleanup levels will govern final acceptance of the remediation.

A11. Included Table 5 has highlighted TPH levels, which are TPH >C12-C28, >C12-C35, >C28- 35 for diesel range

Q12. Background Soil Sample: The Statement of Work references clearance samples matching background sample analysis. Will the Government provide an existing background soil analytical result, or is the contractor required to collect and analyze a separate background sample?

If contractor-provided, please confirm whether the background sample is in addition to the one initial contaminated sample and three clearance samples identified in the Statement of Work.

A12. Please disregard background soil sample. The cleanup level will be specified by TCEQ TRRP Table 5 for TPH

Q13. Number of Clearance Samples: The Statement of Work identifies one initial contaminated sample and three clearance samples but notes that additional samples may be required depending upon the actual depth and width of contamination.

For quotation purposes, should offerors price the stated minimum number of samples only?

If additional clearance samples are required based upon actual field conditions, how will the additional sampling and laboratory costs be addressed?

A13. The Contractor shall include in their quote what is required of the SOW. Contractors are encouraged to include an optional CLIN to address the cost of additional samples, etc.

Contractor is allowed to add line items to their quote and the Government will accept quotes that include both known and unknown quantities for evaluation. Contractor is required to designate which line items are optional. All quotes will be evaluated on a competitive basis utilizing best value as described in the solicitation.

Q14. Required Laboratory Methods: Please confirm the required analytical methods for TPH and BTEX testing. Are any additional analytical parameters presently anticipated by the Government, such as TCLP, VOCs, SVOCs, RCRA metals, ignitability, or other waste-characterization testing? Alternatively, should offerors include only TPH/BTEX plus any additional testing subsequently required by the selected disposal facility?

A14. TPH, BTEX, and possibly TCLP metals will be needed to characterize contaminated soil.

However, the disposal facility chosen by the contractor will be able to specify exactly what analytical parameters are required. TPH will be used for clearance samples.

Q15. Laboratory Turnaround Time: Does the Government require a specific turnaround time for the initial and clearance laboratory samples, such as standard or expedited analysis, or may the contractor determine the appropriate turnaround necessary to meet the overall project schedule?

A15. Contractor may decide appropriate laboratory turnaround time.

Q16. Government Review Turnaround: The Statement of Work requires analytical results to be submitted to 82 CES/CEIE for review before certain stages of excavation, removal, and transportation may proceed. What is the anticipated Government review and approval turnaround time for these analytical submissions?

A16. 82 CES/CEIE will require three (3) business days for review.

Q17. Impact of Government Review on the 60-Day Period of Performance: Please confirm whether time awaiting Government review of laboratory results, waste-profile approval, manifest coordination, or other required Government approvals counts against the contractor’s 60-calendar-day period of performance. If Government review or approval prevents the contractor from proceeding through no fault of the contractor, will the period of performance be adjusted accordingly?

A17. The Government is expected to return submittals in 10 calendar days which is included in the period of performance (POP). If the Government is unable to return a submittal in the expected window, the Government will communicate that to the contractor. If the contractor believes that a late submittal is an impactful reason for disrupting the POP for completion, the

Contractor is to submit a request and justification to extend the POP to the Contracting Officer for review.

Q18. Anticipated Waste Classification: Based upon information currently available to the Government, is the excavated POL-contaminated soil anticipated to be classified as non-hazardous/special waste or RCRA hazardous waste? If characterization has not yet been completed, please confirm that final waste classification will be determined based upon the required; analytical testing and the selected disposal facility’s waste-profile requirements.

A18. The Government has not analyzed the contaminated soil; however, it is anticipated to be non-hazardous waste due to the nature of diesel contaminated soil. Final determination will be made by 82 CES/CEIE utilizing sample results and waste profiling with the disposal facility.

Q19. Groundwater / Contaminated Water: Is groundwater or perched water known or expected within the anticipated excavation depth? If groundwater, contaminated stormwater, or other impacted water is encountered during excavation, is sampling, pumping, containerization, transportation, and disposal of that water included within the current firm-fixed-price scope, or would that condition be addressed separately?

A19. Groundwater is not expected to be an issue during the excavation.

Q20. Existing Underground Utility Information: Are there known underground POL lines, electrical services, communications, water, sewer, storm drainage, or other utilities within or immediately adjacent to the remediation area? If available, could the Government provide existing utility drawings or other known utility information to offerors for pricing and planning purposes?

A20. There is an electric box located near the spill location that operates the intersection traffic lights. Other utility lines may be present. Per SOW Section 1.5, the contractor will complete AF Form 103 (Dig Permit) prior to work which will list utility companies the contractor must contact to obtain utility marking prior to excavation.

Q21. Equipment and Truck Access: Are there any known site conditions that would restrict access by remediation equipment or transportation vehicles, including gate-width limitations, overhead clearances, pavement/load restrictions, security fencing, turning-radius restrictions, or other physical access limitations?

A21. The excavation area is located outside of the perimeter fence of the installation with the access road being the two exit lanes from the old hospital gate (gate is closed). The entrance lanes of the road must remain clear for the trucks entering/exiting the hospital demolition project adjacent to the spill cleanup site.

Q22. Temporary Soil Staging Area: The Statement of Work requires excavated material to remain containerized adjacent to the excavation area while awaiting clearance results and authorization for transportation. Could the Government confirm whether adequate space is available adjacent to the work area for a covered roll-off or similar container and whether there are any limitations on container size or placement?

A22. Adequate space should be available to stage a roll-off container near the excavation site.

Q23. Backfill Quantity: Should offerors assume that the required clean backfill/topsoil quantity will approximately equal the volume of contaminated soil actually removed, beginning with the Government’s estimated eight cubic yards? If not, please provide the quantity or assumptions offerors should use for pricing.

A23. Assume backfill quantity is equal to soil removed.

Q24. Grass Species and Restoration Quantity: Please identify the existing grass species within the affected remediation area. If available, could the Government also provide the approximate square footage of sod or vegetation expected to require restoration?

A24. The expected approximate square footage for grass replacement is 170 square feet.

Q25. Post-Installation Sod Maintenance: Following installation of replacement sod, is the contractor responsible for watering, establishment, maintenance, or replacement of the sod for a specified period prior to final acceptance? If so, please provide the required maintenance duration and acceptance criteria.

A25. 70% grass coverage is required prior to final acceptance.

Q26. HAZWOPER Requirements: Does the Government require personnel performing the soil remediation to maintain OSHA 29 CFR 1910.120 HAZWOPER training, including applicable 40-hour initial training, current 8-hour refresher training, medical surveillance, and/or other HAZWOPER documentation?

A26. This is not required but is a best management practice.

Q27. Base Access Requirements: What information and approximate processing time should the contractor anticipate for employee, subcontractor, remediation vehicle, and equipment access to Sheppard AFB? Please identify whether advance personnel rosters, driver’s licenses, vehicle registration, insurance documentation, background information, or other access documentation will be required.

A27. Excavation work will be performed on installation property, but outside the installation perimeter fence. No access to the installation will be required.

Q28. Previously Unidentified Regulated Materials: The Statement of Work directs the contractor to stop work and notify the Government if previously unidentified suspected asbestos-containing material, lead-based paint, or other regulated material is encountered. Please confirm that any additional investigation, testing, remediation, disposal, schedule impact, or other work resulting from previously unidentified regulated material outside the stated POL-contaminated-soil scope would be addressed through Government direction and, where applicable, a contract modification.

A28. Yes that is the correct approach.

Q29. Final Environmental Acceptance Please identify the Government representative responsible for providing final environmental acceptance of the remediation.

Additionally, please confirm what analytical results, reports, manifests, photographs, restoration documentation, and/or other evidence will constitute satisfactory completion and final acceptance of the soil-remediation requirement.

A29. The Contracting Officer will provide final project acceptance based on the recommendation of the CE personnel. There is no requirement for a formal remediation completion report.

Analytical reports, field documentation, photographs, manifests, weight tickets, and restoration documentation, etc. will satisfy project closeout requirements. The Government will need to provide acceptance of project completion.

Q30. Is there a Release footprint in a KMZ file to perform a desktop review of the impacted area?

A30. No, no KMZ file of the release exists.

Q31. Listed within the scope of work is the grass type to be utilized during backfill. Multiple types of grass are listed however, unknown areas of excavation or ground disturbances. Which type is to be used and how many pounds live seed are to be utilized during seeding?

A31. Follow Table 2-5 Planting List for Grasses on Improved Grounds. Follow Table 2-7 for Grass Planting Schedule.

Q32. Specifications for the backfill material to be utilized only states that it is to be inspected ‘by the Grounds Contracting Officer's Representative, USDA Wildlife Biologist, or Natural Resource Manager’ is this provided by the Base or is this to be performed prior to arrival on site?

A32. These representatives are installation personnel that will perform the inspection.

Q33. The area of impact was caused by a diesel spill, thus BTEX typically wouldn’t be an indicator compound for closure under TCEQ-TRRP. PAHs would likely be considered for regulatory screening purposes since it’s an indicator analysis for diesel range organics, along with TPH-1005 or TPH-1006.

A33. For this case please utilize BTEX and the TPH 1005.

Q34. Was the spill reported since it was over an RQ? If so, is who is completing the final reporting to the agency or is it required?

A34. 82 CES/CEIE reported to TCEQ and will complete the final reporting.

Q35. Are there photos of the area used to develop the estimated eight cubic yards of contaminated soil?

A35. Currently, CEIE does not possess any photos of the soil, but measurements of the affected area were taken.

Q36. “Collecting initial contaminated soil samples and clearance samples in accordance with TCEQ TX Risk Reduction Program requirements.”

Clarification - Under the solicitation Description/Background/Work Details/Item #1. Is the intent to have the “initial contaminated soil samples” referenced to be collected pre-excavation for analysis/delineation or is the reference for removed soil waste characterization sampling post excavation for disposal?

A36. The sample can be taken post excavation for both analysis and waste characterization.

Q37. Can you identify the approximate excavation area and anticipated depth based upon any prior knowledge?

Approximate excavation area is 17’ by 10’. However, the depth is unknown.

Q38. Where specifically can the soil containers be staged?

A38. After contract award, a submittal will be needed for the contractor to submit a recommendation of a lay-down area. The Government will either approve or recommend a different lay-down area.

Q39. Will air monitoring be required for vapors or PM10/2.5 during remediation operations?

A39. No, no air monitoring is being required.

Q40. Are there any Base monitoring or security requirements for the staged waste or for monitoring the excavation during the confirmation sample analysis and approval?

A40. Yes, fence fabric and other safety hazard warning indicators should be put in place to prohibit access.

Q41. Are there utilities or structures within or immediately adjacent to the excavation area?

A41. This will be determined when the Dig Permit is completed.

Q42. Will the underground utility clearance be handled by the Base or Texas 811?

A42. The contractor will work with the Base to get clearance with our utility crews during the Dig Permit process.

Q43. What was the source of the POL release?

A43. A haul truck struck the fence, resulting in a release of diesel from the fuel tank.

Q44. Is there any chance that solvents or hazardous materials were a part of the release? May affect confirmation analytical, disposal facility, and H&S protocols?

A44. No, the release was only diesel.

Q45. What existing data are available that define the horizontal and vertical extent and constituent/concentrations of the POL contamination?

A45. A contaminated area was measured to be 17’ by 10’. However, depth is unknown.

Q46. Please confirm the specific TRRP cleanup criteria that will be used to determine successful remediation, including the applicable source-area assumption (e.g., 0.5-acre versus 30-acre commercial/industrial PCLs) and the specific TPH/BTEX criteria that clearance samples will be compared against.

A46. Please use the 0.5 acre source area.

Q47. TCEQ TX Risk Reduction Program (TRRP) requirements are stipulated. Is Plan B acceptable or will we be required to remove to Plan A?

A47. We are only using the TRRP table as a guidance for clearance sampling, not necessarily requiring cleanup to Plan A or B.

Q48. Any concerns for GW impact? TCEQ may want sampling and confirmation? Are there similar releases on Base that have resulted in GW impact?

A48. No groundwater concerns at this time.

Q49. Has TCEQ been notified of the spill?

A49. Yes, TCEQ received a report of the spill. Final closeouts from the project will be provided to TCEQ to show compliance.

Q50. Is there an on Base borrow source for the excavation backfill that is already compliant with Base requirements, or will we be required to source offsite and provide soil certifications to meet the requirements?

A50. Currently, there is not a source for backfill already on the Base. This will need to be sourced offsite.

Q51. The SOW calls for offsite disposal of excavated impacted soils. Is landfarming bioremediation an acceptable method for disposal?

A51. Please dispose of contaminated soil at a landfill.

Q52. Regarding H&S and H&S Plan will the Base Emergency Medical Services be the appropriate call out for a safety incident or is the site officially off Base and the local EMS would be the proper responding agency?

A52. Base emergency response responded to the initial incident, so I would think that they would still be the proper agency in case of an emergency.

Q53. Is there an existing greenfield identified as representative of soil background on Base based upon previous works at the facility?

A53. No, please utilize the TRRP chart.

Q54. Are we to assume that a TCEQ SWP3 will not be required due to the small area of disturbance? If a SWP3 is not applicable, we would still install and maintain industry standard BMPs for the period of time when soil cover is not in place.

A54. A SWP3 will not be required due to the size. However, BMPs should shill be implemented when soil is disturbed prior to backfill.

Q55. For TPH analysis, is TCEQ Method TX1005 required, including reporting of the applicable carbon ranges, or will another TPH method be accepted? Please also confirm the required analytical method for BTEX.

A55. Yes. For TPH please utilize the Method TX1005. For BTEX please utilize method SW-846 8260C.

Q56. Following submission of initial or clearance analytical results, what review/approval turnaround should the Contractor assume for 82 CES/CEIE?

A56. 82 CES/CEIE will need three (3) business days for review.

Q57. Will the Contractor be permitted to backfill immediately following written 82 CES/CEIE acceptance of clearance results, or is a separate field inspection/approval required prior to backfill?

A57. The soil must be inspected by the Grounds Contracting Officer’s Representative, USDA Wildlife Biologist, or the Natural Resource Manager prior to backfill.

Q58. Is the Contractor required to submit a formal remediation completion report, or will analytical reports, field documentation, photographs, manifests, weight tickets, and restoration documentation satisfy project closeout requirements?

A58. There is no requirement for a formal remediation completion report. Analytical reports, field documentation, photographs, manifests, weight tickets, and restoration documentation, etc.

will satisfy project closeout requirements. The Government will need to provide acceptance of project completion.

Q59. Is the estimated 8 cubic yards based on sampling? If contamination extends beyond 8 CY, will additional excavation, testing, disposal, backfill, and sod be paid by unit price or change order?

A59. Quote should include the estimated eight cubic yards. Contractor will need to submit a Request for Information (RFI) for unforeseen site condition to initiate a mod if needed for work required beyond the initial estimated area of contamination.

Q60. While clearance results are pending, may the excavation remain open behind temporary fencing, or must it be plated or temporarily backfilled?

A60. It can remain open behind temporary fencing.

Q61. Where can equipment, the covered contaminated-soil container, clean fill, and sod be staged?

A61. After contract award, a submittal will be needed for the contractor to submit a recommendation of a lay-down area. The Government will either approve or recommend a different lay-down area.

Q62. Does the 60-day period include sampling, government review, disposal, backfill, sod establishment, and closeout? What pre-work plans and submittals are required?

A62. This requirement is not governed by RFO Part 36 and does not follow standard construction guidelines, while common industry practices are useful.
