CIMC Sites

EPA "Cleanups in My Community" (CIMC) national Sites FeatureServer — spans Superfund/NPL, RCRA Corrective Action, Brownfields, Federal Facilities, and OSC removals with per-program institutional/engineering-control indicators. Multi-attribute source: US_INST_CONTROL (Integration 190) and US_ENG_CONTROLS (Integration 189). Distinct from state-level INST_CONTROL sources (e.g. ny_dec__institutional_controls) — this is the national counterpart, no overlap. Composite PK (REGISTRY_ID, SF_SITE_ID, RCRA_HANDLER_ID, BF_PROPERTY_ID, EPAOSC_SITE_ID). Caveat: SF_IC_IND uses an undocumented numeric code domain (1/2/3/4), no published legend found; non-blank treated as "IC tracked" as the most defensible fallback, could overcount ds_US_INST_CONTROL by up to ~516 rows — see .md for detail.
