Mission Support for Preparation of Toxicological Profiles

The CDC Pittsburgh established this Master IDIQ on September 10, 2018, to provide mission support for the preparation of toxicological profiles required under the Comprehensive Environmental Response, Compensation, and Liability Act and the Superfund Amendments and Reauthorization Act. Ordering closed on September 8, 2023, and the vehicle is no longer available for new task orders.

The vehicle is inactive and substantially spent. All 21 awarded task orders have completed or will complete by late 2024. The most recent order was issued on June 26, 2023. Combined task-order potential value is $11.2 million, with $11.1 million obligated (99% of the ceiling), against a $10 million shared vehicle ceiling. The vehicle generated three to six orders per year between 2019 and 2021, declining to four orders in 2022 and one in 2023.

Work centers on developing toxicological profiles and supporting scientific documents that inform federal, state, and local health professionals and public health assessors on human exposure to hazardous substances. Task orders employ both firm fixed price and time-and-materials pricing. Recent orders range from approximately $23,000 to $976,000 in obligated value, with typical durations of six to twelve months.

Competition is heavily concentrated. SRC Inc. holds 16 of 21 orders ($9.1 million combined potential value, 81% of vehicle activity), while ABT Global LLC holds the remaining five orders ($2.1 million combined potential value). All orders are unrestricted, non-set-aside awards. All work funds CDC Pittsburgh requirements; no other agencies place orders under the vehicle.

The sourcing landscape for follow-on requirements is unclear. CDC Pittsburgh issued a sources-sought notice in November 2017 classifying the work under NAICS 541690 (Other Scientific and Technical Consulting Services, $15 million size standard) and noted it was exploring whether a set-aside would be possible, but no successor vehicle appears in the source materials. Firms interested in this technical area should monitor CDC Pittsburgh procurement channels for renewal or recompetition activity.

The Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA) are required to establish guidelines for the development of toxicological profiles. The development of toxicological profiles and other scientific documents continue to support federal, state and local health professionals, public health assessors, and numerous groups and individuals in understanding the potential for human exposure to various hazardous substances.
