Floodplain indicator

Public Maine DEP point-layer subset of the statewide registered petroleum tanks database, limited to aboveground tanks and providing facility, location, tank, water-proximity, installation, status, and capacity details.

EPA's national UST Finder ArcGIS FeatureServer (Releases layer), server-side filtered to Maryland releases reported before 1999-01-01 — the frozen pre-1999 slice of MDE's legacy 'Recovery Sites Database,' distinct from MDE's live OCP case system (already covered by md_mde__ocp_case_search). 4,543 rows, no auth, paginated via resultOffset/resultRecordCount. Note: this data overlaps with the separately-scoped us_epa__ust_finder source — both draw from what is verifiably the same underlying UST Finder Releases dataset (published via two distinct-but-data-identical ArcGIS items), and this Maryland/pre-1999 slice is fully reproducible by filtering us_epa__ust_finder's fetched output. Kept as an isolated single-attribute source per the developer's explicit decision (Integration 216) rather than folded into the multi-attribute us_epa__ust_finder source.

EPA's national UST Finder ArcGIS FeatureServer (Releases layer, item US_Underground_Storage_Tank_2019), server-side filtered to State='New Jersey' — 16,816 leaking underground storage tank (LUST) release records covering New Jersey's full release history regardless of status (4,672 Open, 12,144 No Further Action/closed). This is a NJ-filtered slice of EPA's UST Finder Releases dataset, not a source published directly by NJDEP; NJDEP's own DataMiner LUST portal was investigated first and abandoned due to an hCaptcha wall with no programmatic bypass. Note: this data has been verified to overlap byte-for-byte (identical LUST_ID sets) with the separately-scoped us_epa__ust_finder source, which draws from a newer-but-data-identical ArcGIS item (UST_Finder_Feature_Layer_2). Kept as a standalone single-attribute source per established developer precedent (Integrations 216/294) rather than folded into the multi-attribute source.
