Increase to Multi-Award IDIQ ceiling for Basic Environmental Support Services

The Basic Environmental Support Services IV (BESS IV) is an 8(a) Multiple Award Task Order Contract (MATOC).

Under 10 U.S.C. § 3204(a)(1), as implemented by RFO 6.103-1, agencies may contract without providing for full and open competition when the required services are available from only one responsible source, or for the DoD, from only a limited number of responsible sources, and no other type of services will satisfy agency requirements.This ceiling increase restricts competition to the limited number of responsible sources currently holding BESS IV contracts (a pre-qualified pool of four 8(a) contractors).

Because these four contractors have already been deemed technically acceptable, possess active APG security badging, have approved Health and Safety Plans, and are currently mobilized on-site, they are the only sources capable of satisfying the agency's requirements without causing a catastrophic lapse in mandatory environmental compliance services.In accordance with DFARS PGI 206.104-71, a Sources Sought Notice/RFI was posted to SAM.gov on 01 July 2026. No responses were received from vendors outside the current MATOC pool capable of meeting the immediate mobilization and badging requirements.
