Read the date rules
Explicit sourced stage dates only. Source-check and publication dates never fill missing stages. Several stages or phases can belong to one record.
Operator-reported opening dates retain that qualification. An announcement can describe a phase, application or reported delivery. The dated record does not reconstruct every site status in past years.
Dated concern items.
Counts describe attributed documentation. Categories can overlap; a news report, public concern, permit item, legal action, regulator record and formal complaint keep their separate record types.
United States · All categories · All record types
69 of 111 documented items have an exact event date through October 21, 2026. 42 stay undated in this view.

Read the concern date rules
Exact attributed concern event dates only. Unknown event dates stay outside the dated bars. Categories overlap and record types remain separate.
Source publication, disposition and source-check dates remain distinct from event dates. Empty years or categories do not establish that no concern was raised.
