Environmental Services (FSS-899)

GSA Federal Acquisition Service established the Environmental Services Master GSA Schedule (Schedule 899) on April 6, 1999, and is phasing it out; new orders may be placed through September 11, 2106. This is a legacy vehicle: GSA no longer awards new Federal Supply Schedule contracts under Schedule 899, with services transitioning to The Professional Services Schedule (PSS or 00CORP). Delivery order activity may continue under Schedule 899 until all vendor-level contracts and orders expire.

Order momentum has declined sharply. The vehicle received 163 orders in 2016, declining to just 3 orders in 2020 and none since February 27, 2020. Over the vehicle's entire life, 5,246 task orders worth $3.43 billion in combined potential value have been issued; $3.42 billion (100 percent) has already been obligated. The vehicle served 389 distinct customer agencies across 62 prime contractors, with 99 percent of orders issued under no set-aside.

Logistics Management Institute dominates the portfolio, holding 1,217 orders (23 percent of the total) worth $1.68 billion in combined potential value. The top five primes—LMI, Tetra Tech Inc., Prizim Inc., Eastern Research Group Inc., and Booz Allen Hamilton Inc.—account for roughly 50 percent of all orders. By potential value, LMI, Booz Allen Hamilton ($248.4 million), Navarro Research and Engineering Inc. ($238.9 million), Eastern Research Group ($190.9 million), and Leidos Inc. ($158.2 million) together hold 73 percent of the combined potential value.

Orders span environmental consulting, environmental training, recycling and waste disposal services, and geographic information systems (GIS) work. Recent orders show diverse scope: remediation and characterization studies, natural resource monitoring and inventories, cultural resource surveys, compliance and audit services, sustainability support, hazardous waste cleanup, and industrial hygiene assessments. Many recent awards reference a parent schedule of The Professional Services Schedule, reflecting the transition in progress.

The Department of the Army, National Park Service National Office, Office of the Secretary of Defense, Environmental Protection Agency Office for Air and Radiation, and EPA Region 9 together account for 19 percent of all orders. Defense and environmental agencies predominate. Typical obligated values on recent orders range from under $25,000 to over $54 million, with firm fixed price and time-and-materials pricing structures both present.

Given the vehicle's sunset status, absence of new orders since early 2020, and full obligation of the combined potential value, pursuit should focus on vendor onboarding to PSS rather than leveraging Schedule 899 directly.

This is the summary page for contract activity under the LEGACY Schedule 899 Master Federal Supply Schedule for Environmental Services. GSA is no longer awarding new Federal Supply Schedule contracts under this vehicle as it is being phased out. Services formerly procured under Schedule 899 are being transitioned to The Professional Services Schedule (PSS), also referred to as 00CORP or The Consolidated Schedule. Delivery order activity under this vehicle may continue until all of the vendor-level Federal Supply Schedule contracts, and the delivery orders themselves, have expired. Contract activity contained under this LEGACY vehicle is for companies that did not move over to PSS, or that did move over to PSS but did so under a new contract number. Services procured under this schedule included various environmental consulting services including environmental training, recycling and waste disposal services, and geographic information systems (GIS) services.
