# Passive Institutional Controls
**Domain:** Deep Time / Institutional Memory / Nuclear Governance
**Doc Type:** Canonical Wiki Entry
**Maturity:** Developed
**Evidence / Concept Status:** Established EPA/DOE regulatory concept
## Definition
**Passive Institutional Controls** are durable markers, records, archives, land records, government ownership, and other mechanisms designed to preserve knowledge of a hazardous site after active institutional control may end.
## Why It Matters for Deep Time Continuity
They are a direct precedent for preserving warnings and institutional meaning after the original operating organization disappears.
## Existing Architecture / Evidence
EPA's WIPP framework treats markers, public records and archives, government ownership, land-use restrictions, and other knowledge-preservation measures as passive institutional controls.
## Deep-Time Continuity Analysis
A continuity analogue would preserve identity, election, provenance, rights, custody limits, and restoration instructions across institutional mortality.
## Evidentiary Boundary
The regulatory source concerns radioactive waste and human intrusion.
