How OPEF fits

The operating record between project teams, consultants, and agency review.

OPEF connects evidence, comments, decisions, citations, and exports so environmental review work stays traceable from first trigger to final package.

The status quo

Environmental review breaks when the record fragments.

Permitting teams still coordinate across email, shared drives, consultant folders, and agency portals. When the project changes, nothing stays linked through to export.

Fragmented permitting inputs across disconnected tools
  • 01

    Review path decided late

    Studies and drafts start before the federal nexus and likely CATEX, EA, or EIS pathway are clear.

  • 02

    Evidence loses its thread

    Maps, studies, photos, and comments live in different places with no stable link back to the project record.

  • 03

    Exports rebuilt under pressure

    Final packages are assembled manually while deadlines compress and reviewer questions pile up.

Usually scattered across

  • Email threads
  • PDF folders
  • GIS files
  • Consultant drafts
  • Agency comments
  • Site photos
  • Spreadsheets
  • Versioned Word docs

Review paths

One workspace across every review path.

Route the federal nexus, likely lead-agency pathway, and CATEX / EA / EIS fit before studies pile up in PDFs and email.

PathWhen it appliesOPEF helps with
01Federal nexus

Permit, funding, approval, lease, or federal action

Trigger screening and lead-agency routing

02CATEX

Exclusion likely applies

Extraordinary-circumstances checks and rationale

03EA / FONSI

Alternatives, affected resources, mitigation, finding support

04EIS / ROD

Scoping, comments, alternatives, record management

Project record

One canonical record from trigger to export.

Project basis, site evidence, studies, and review history live in one dataset. Every comment, design change, and export references the same source-linked objects.
