About this opportunity
The Department of the Interior National Park Service Midwest Region awarded contract 140P6326P0034 on a sole-source basis for emergency radon mitigation at Jewel Cave National Monument on August 21, 2026.
The justification cites urgent and compelling circumstances under Executive Order 14398. Testing conducted in March 2026 identified radon concentrations of 9.5 pCi/L in Quarters 35, exceeding the EPA action level of 4.0 pCi/L and creating immediate health risks to employees. The Park conducted limited market research by reaching out to local radon mitigation contractors; Upper Edge responded immediately and verified the testing findings. The contracting officer, Joanie M. Brzezinski, certified on June 29, 2026 that urgent and compelling circumstances justified sole-source procurement, determining that delayed procurement through extended market research would prolong employee exposure to elevated radon levels. The mitigation system will serve an eight-unit apartment complex encompassing approximately 2,389 total square feet. Fair and reasonable pricing will be determined using FAR Part 13.106-3(a) price analysis techniques. The facility manager, David Tashner, signed the justification on June 29, 2026. The procurement is categorized under NAICS 238990 (All Other Specialty Trade Contractors) and PSC Z2FA (Repair Or Alteration Of Family Housing Facilities).
