Research Supplements at NIEHS

Office Worker

NIH does not allow supplements during a No-Cost Extension (NCE) period (including mid-project NCEs). Applications submitted during an NCE will not be considered by NIEHS.

Recipients of NIEHS research grants with a reasonable period of research support (usually two years or more) remaining in the project period at the anticipated time of the supplement award (3-6 months after application submission) are eligible to submit a request to NIEHS for an administrative supplement to the grant.

NIEHS categorizes administrative supplement requests in five major areas:

  • General Administrative Supplements provide funding for emergencies/unanticipated needs, ones that could not have been foreseen at the time of the previous competing or non-competitive application, and that seriously impact the ability of the recipient to accomplish the project Aims.
  • Superfund Research Program Supplements are intended to meet specific programmatic needs and are issued using a Notice of Special Interest.
  • Worker Training Program Supplements are intended to meet specific programmatic needs and are issued using a Notice of Special Interest.
  • Ad Hoc NIH Supplement Programs are intended to meet specific programmatic needs and are issued using a Notice of Special Interest.

**The receipt dates apply to all general administrative supplements and Superfund supplements.

Supplements will generally not be awarded to recipients if they:

  • Are in a No-Cost Extension (including mid-project No-Cost Extensions).
  • Do not have enough time remaining in the current budget period to obligate the supplemental funds.
  • Have a history of carrying large and growing unobligated balances over time or have a large unobligated balance remaining from previous budget periods.

General Administrative Supplements

General administrative supplemental funds can be requested for emergency or other unforeseen situations, such as natural or manmade disasters that damage the PI's lab or other research resources, failure of essential equipment, unforeseen costs associated with loss of biospecimens or samples, or increased costs of recruiting subjects or performing laboratory analyses. These requests are considered the highest priority.

Two other types of general administrative supplement requests can be considered but are of lower priority; recipients should contact their Program Officer about these prior to submission to discuss.

Superfund Research Program Supplements

The Superfund Research program provides administrative supplements to SRP Recipients. For more information, please visit the SRP General Supplement webpage.

Per the instructions provided in the NOFOs listed on the webpage above, supplement applications must be submitted electronically to Grants.gov.

Recipients are highly encouraged to contact their assigned SRP Program Officer before submitting an administrative supplement application.

Worker Training Program Supplements

The Worker Training Program provides administrative supplements to support the training of workers who may be exposed to hazardous materials encountered during hazardous waste operations, hazardous materials transportation, and environmental restoration of contaminated facilities or chemical emergency response. Supplements are also granted to address emerging occupational hazards, new regulations, response to natural or man-made disasters, or unforeseen issues and emergencies. For more information, please contact your program officer.

Per the instructions provided in the NOFOs listed above, supplement applications must be submitted electronically to Grants.gov.
