Report.

7-Mar-2025 Project Phasing & Scheduling:

Are there any anticipated phasing requirements for the remediation activities, or will the contractor have flexibility in scheduling tasks within the period of performance?

CZO Brad Bashore

Per the Sampling & Analysis Plan, LTM groundwater monitoring is performed semiannually, annually, or biennially. Semiannual groundwater monitoring wells are sampled in the spring and fall of each year, and annual groundwater monitoring wells are sampled in the spring. Biennial groundwater monitoring wells are sampled in the spring of even-numbered years along with the annual groundwater monitoring wells.

7-Mar-2025

Prior to initiating further remedial actions, we recommend AF consider requiring Contractors to utilize High-Resolution

Site Characterization (HRSC) technologies at each site to verify/update the current CSM. Efficiently collected HRSC data can better define the lateral and vertical extents of VOC and NAPL contaminant bodies and concurrently provide stratigraphic and hydrogeological data useful for identifying confining and transmissive soil units. This high-resolution data could inform and improve remedial design, enabling more efficient and targeted remedial application. These results could also be used as an additional comparison baseline for remedial progress throughout ORC completion, without requiring additional lab samples and associated lab turn-around times.

CZO Brad Bashore

The Sampling & Analysis Plan (SAP) is currently being optimized/revised which may require additional sampling and contingency measures to evaluate the effectiveness of MNA and verify/update the CSM. The pending revision to the

SAP is being negotiated with regulators and the final version will be released upon completion.

7-Mar-2025 We recommend AF consider requiring Contractors to utilize High-Resolution Site Characterization (HRSC) technologies at logical milestones during completion of the ORC. Results can be compared to the initial baseline assessment to provide real-time assessment of remedial progress.

CZO Brad Bashore

The Sampling & Analysis Plan (SAP) is currently being optimized/revised which may require additional sampling and contingency measures to evaluate the effectiveness of MNA and verify/update the CSM. The pending revision to the

SAP is being negotiated with regulators and the final version will be released upon completion.

7-Mar-2025 In addition to the VOC and NAPL data, some HRSC technologies can collect multiple, discrete, targeted groundwater samples during a single advancement. These tools can also collect stratigraphic and hydrogeologic data, allowing repeated targeting of discrete, impacted intervals identified previously.

CZO Brad Bashore

The Sampling & Analysis Plan (SAP) is currently being optimized/revised which may require additional sampling and contingency measures to evaluate the effectiveness of MNA and verify/update the CSM. The pending revision to the

SAP is being negotiated with regulators and the final version will be released upon completion.

7-Mar-2025

The PWS states: “This scope includes all known contaminants linked to the specific sites per Table 1 of the SOO

(includes contaminants on, under, or sourced at/migrating from the specific sites) without regard to quantity (e.g., plume size, concentrations). See reference to Section 1.3.2 of this SOO for exclusions .”

and

"In addition to the requirements identified in Table 1, the Contractor shall be responsible for:

c. Contaminants for which there are promulgated federal, state, or local standards.

f. Ensuring that remedial actions do not negatively impact the distribution of any other contaminants and/or emerging contaminants (e.g., PFAS, 1,4-dioxane) ”

PFAS and 1-4 Dioxane have promulgated federal and state standards.

1. Can the government clarify if the scope includes PFAS and 1,-4 Dioxane and not just chlorinated solvents and chromium that are in the current ROD Amendment 1?

2. If PFAS and 1-4 Dioxane are included in the scope, has the government determined the nature and extent of these contaminants onsite at AFP4, offsite at NAS JRB Fort Worth (including on base housing area), offsite at the Hawks

Creek Golf Course, and other adjacent offsite property (City of White Settlement) and potable water wells that existing on adjacent offsite property?

3. Is the contractor to assume that any treatment required to meet the performance standard under this ORC for chlorinated contaminants will not require treatment of PFAS and 1,4-Dioxane to meet effluent standards for discharge to the City of Fort Worth POTW and that a separate contractor or new task order will be responsible for any required

CZO Brad Bashore

1. The scope includes 1,4-dioxane but not PFAS.

2. The nature and extent of 1,4-dioxane has not been delineated either on or off

AFP 4.

3. Correct, a separate contractor or new task order would be responsible for any required PFAS and/or 1,4-dioxane treatment.

7-Mar-2025

The PWS states: “The Contractor will be required to create and implement an approved Groundwater Sampling and

Analysis Plan that will meet the ROD Amendment requirements. This must include a Groundwater Evaluation

Program that demonstrates MNA will achieve objectives established in the ROD Amendment. ”

1. Approval of the plan is not referenced in Table 1: Performance Table as a performance standard. Is regulatory approval of the Groundwater Sampling and Analysis Plan by USEPA and TCEQ required? Please clarify.

2. If the plan requires only AF approval and USEPA and/or TCEQ will not approve it, how can the contractor be contractually bound to achieving the stated performance standard of “…AF and regulatory approval of RA-O documentation” for LF003 and OT022, when the regulators do not accept the plan to document RA-O is being achieved in accordance with the ROD amendment?

3. Can the government clarify if the contractor can assume the sampling network specified in the Focused Feasibility

Study for the preferred alternative is sufficient? Will MNA parameters need to be monitored during every sample event?

4. Have the government and regulators determined what event/conditions would trigger a contigency technology be implemented in lieu of MNA?

CZO Brad Bashore

1. The Groundwater Sampling & Analysis Plan is a component of the "Basewide

Quality Program Plans (QPP), which does require USEPA and TCEQ approval.

2. Please see above response in regards to regulatory approvals.

3. Yes, although the Sampling & Analysis Plan (SAP) is currently being revised, the contractor can assume the sampling network specified in the Focused

Feasibility Study for the preferred alternative is sufficient. Also the contractor can assume that MNA parameters will be monitored during biennial sampling events.

4. The government and regulators have not yet determined what would trigger contingency technology.

Table 1 indicates that the contractor will update the LUCIP.

1. A LUCIP is not currently availble on the Administrative Record. Can the government provide the current LUCIP?

2. Has the EPA/TCEQ provided guidance on the institution control requirements that were to be implemented under

ROD Amendment 1 for each of the groundwater units? Can the goverment clarify if these will be a part of the LUCIP plan?

CZO Brad Bashore

1. The LUCIP is an internal document not available to the public. Requirements for implementing land use controls are best referenced in the Administrative

Record for AFP 4 (e.g. Annual Inspection Report - #13173).

2. The Draft-Final LUCIP (specific to ROD Amendment I) is currently under

USEPA and TCEQ review. However, the guidance on the institutional control requirements that were to be implemented under ROD Amendment I will apply for each groundwater unit.
