Repair Base Switching Station

Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the procedures for collecting and analyzing samples to characterize PCB remediation waste at the Building 1406 demolition site, in compliance with federal regulations and EPA standard operating procedures.

• Sampling Strategy: A targeted approach will be used, focusing on high-probability contamination areas. A minimum of three samples will be collected from each type of porous surface at each location. In general areas where PCB equipment was formerly used or stored, at least 1 sample per 100 square feet will be collected.

• Media & Locations:

  • Concrete: Primary (Biased) locations include pads beneath former equipment and stained areas. Secondary locations include general flooring, curbs, and trenches.
  • Soil: Primary (Biased) locations are adjacent to and downslope from concrete pads. Secondary locations form a perimeter around the work area.

• Sampling Methodologies:

  • Porous Surfaces (Concrete): Collect fine powder from the top 0.5 inches using a rotary impact hammer.
  • Soil: Incremental Sampling Methodology (ISM) involves collecting 30-50 small increments from 0-6 inches deep within each Decision Unit, combined to create one representative sample.

• Sample Collection & Handling:

  • Equipment decontamination procedures are specified.
  • Nitrile gloves are required.
  • Samples will be stored in 8-ounce glass jars with Teflon-lined lids.
  • Labeling will include unique ID, date, time, location, and sampler's initials.
  • Chain of Custody will be maintained.
  • Quality Control includes one Field Duplicate and one Equipment Blank per 20 samples.

• Laboratory Analysis:

  • Performed by a state-certified laboratory experienced in PCB analysis.
  • Analytical Method: EPA SW-846 Method 8082A (Gas Chromatography).
  • Extraction Method: EPA Method 3540C (Soxhlet Extraction) for solid matrices.
  • Reporting Limit: Must be 1.0 mg/kg (ppm) or lower.

• Analytical results will be compared to TSCA regulatory action levels.

• Action Levels:

  • < 1 ppm: Non-Impacted (manage as standard construction debris).
  • 1 ppm to < 50 ppm: PCB Remediation Waste (excavate, segregate, and dispose of in a permitted municipal solid waste or industrial landfill).
  • ≥ 50 ppm: TSCA-Regulated (Hazardous) Waste (excavate, segregate, and dispose of at a licensed TSCA chemical waste landfill).

• Additional "step-out" samples will be collected if initial samples exceed 1.0 ppm to delineate contamination boundaries.

• Not explicitly stated, but pertains to the Building 1406 demolition site.

• Health and Safety: Personnel must adhere to strict protocols, including eye, respiratory, and hearing protection. A fitted respirator is mandatory for hard porous surface sampling.

• Personnel Qualifications: Samplers must meet hazardous materials/waste site work qualifications, including a 40-hour HAZWOPER course and annual refresher. Training in document-specific procedures by an experienced sampler is required.

A comprehensive Site Characterization and Removal Plan Report will be compiled upon receipt of analytical data, including methodology summary, maps of sample locations and results, laboratory data sheets, and a work plan for abatement and disposal.

Questions & Answers / Clarifications

This document provides Frequently Asked Questions (FAQs) regarding the REAL ID Act and its implications for accessing DoD installations, specifically MHAFB. It clarifies identification requirements for personnel and visitors.

• REAL ID Act Compliance Deadline: As of May 7, 2025, non-REAL ID Act compliant state-issued driver's licenses or identification credentials will no longer be accepted for identity proofing at DoD installations.
• Accepted Identification: Only REAL ID Act compliant driver's licenses/identification credentials (marked with a star) or other approved forms of identification will be accepted for identity proofing.
• Alternative Forms of ID: Several alternative forms of identification are accepted, including State-issued Enhanced Driver's Licenses, U.S. Passports, U.S. Passport Cards, DHS trusted traveler cards, U.S. Department of Defense IDs, Permanent Resident Cards, federally recognized Tribal Nation IDs, HSPD-12 PIV cards, and foreign government-issued passports.
• Non-Compliant IDs: Jurisdictions can still issue non-compliant licenses, but they must clearly state they are not acceptable for official purposes.
• Enhanced Driver's Licenses (EDL/EID): These are accepted as border-crossing documents and are an acceptable alternative to REAL ID.
• Minors: Identification is not required for children under 18; the sponsor will need acceptable identification.
• Installation Access: A REAL ID Act compliant ID is for identification purposes only; all visitors must still meet other access requirements and background checks.
• Proof of US Residency: REAL ID compliant IDs are not proof of US residency. Only specific documents like Permanent Resident Cards or certain foreign passports with stamps/visas are considered proof of US residency for installation access.
• Multiple Credentials: Individuals with multiple credentials must use the one that most accurately depicts their capacity for the specific visit (e.g., a contractor must use contractor identification, not retiree ID).

This FAQ directly impacts any opportunity requiring access to DoD installations, as it specifies the required forms of identification for personnel and visitors, effective May 7, 2025. Bidders should ensure their personnel and any visitors associated with the contract meet these identification requirements.
