  "definition": "1. This event signifies the establishment of engineering controls (ECs) as part of, or to augment, an interim or final corrective action. ECs consist of engineering measures (e.g, caps, treatment systems, etc.) designed to minimize the potential for human exposure to contamination by either limiting direct contact with contaminated areas or controlling migration of contaminants through environmental media. When ECs are established at the facility level (e.g., site security), this event should be linked to the \"entire facility\" area. When ECs are established and affect only portions of the RCRA facility, this event should be linked to the specific area affected by the control.\n\n2. This event should also be entered when ECs are established for regulated units undergoing closure and/or post-closure care, including engineering controls required under 40 CFR 264 and 265.\n\n3. A status code of GW should be entered for groundwater control which includes any EC pertaining to groundwater, including in situ and ex situ treatment like bioremediation, in situ permeable reactor barriers, monitored natural attenuation (MNA), long-term monitoring, etc.",
