How long is the period of performance for EN assistance agreements?

The period of performance for EN grants is standardized at 3 years. The start date for each new EN awards is October 1st of that year, and the end date would be three years later as we have a standard three-year period-of-performance.

Grantees can finish their projects early within this three-year period, and EPA can also issue no-cost extensions if the project isn’t completed at the end of the three years (up to 4 times, for a total project period of up to 7 years). However, we highly encourage avoiding extensions wherever possible to avoid the associated processing and paperwork.

There is also no penalty if the applicant is not able to immediately start their work on October 1. From an application standpoint, however, applicants should include project goal and output scheduled completion dates which fit within the period of performance, October 1, [year listed on the SN] - September 30, [three years past start date].
