Funding posture
Rare NOFOs under a mega ceiling
Environmental Cleanup pairs a mega SAM.gov ceiling ($1.0 million to $20.0 million) with a sparse Grants.gov trail (2 indexed rows). Large paper capacity, few public solicitations: watch the open flags on those scarce listings rather than expecting a steady NOFO cadence.
Assistance Listing text · DOE
Grants to support regulatory oversight of DOE environmental cleanup activities at former nuclear sites.
Multi-door applicant board · 2 SAM.gov types
CFDA 81.135 prints 2 distinct applicant types (State or Local Government, Tribal Organization). Environmental Cleanup is a broad multi-door Assistance Listing, filter fit before reading NOFO volume as demand.

Across 221 indexed Grants.gov listings under CFDA 81.135, no single funding instrument dominates: 44 grant, 107 cooperative-agreement, and 7 procurement-contract listings. 51% of the indexed listings require applicant cost-sharing.
