Data sources
EPA ECHO — this facility's detailed report — facility, compliance summary, permits, evaluations & violations
RCRAInfo evaluation and violation records for this facility are integrated into the
ECHO report linked above — RCRAInfo's own public search doesn't offer a stable
per-facility link. General source: EPA ECHO, EPA RCRAInfo.
Compliance, permit, and location data come straight from EPA and can't be edited.
Contact info and description come from the business's claimed listing, if any.

Two different dates can appear on this page, and both are correct but mean different
things: "Source snapshot pulled" above is when we last pulled that source's raw data
— this is the date to check for source currency. "Recalculated" on the compliance
summary is when we last recomputed that summary from the data on hand, which can
land on a later date than the source pull itself — a later recalculation date does
NOT mean the underlying source has data through that date.
