NPL Superfund Institutional Control Boundaries (EPA Public)

This GIS dataset contains polygons depicting U.S. EPA Superfund Institutional Control boundaries. Institutional controls are non-engineered instruments, such as administrative and legal controls, that help to minimize the potential for exposure to contamination and/or protect the integrity of a response action. ICs typically are designed to work by limiting land and/or resource use or by providing information that helps modify or guide human behavior at a site. Superfund features are managed by regional teams of geospatial professionals and remedial program managers (RPMs), and SEGS harvests regional data on a weekly basis to refresh the national dataset and feature services.本地理信息系统（Geographic Information System, GIS）数据集包含描绘美国环境保护署（U.S. Environmental Protection Agency, EPA）超级基金制度管控边界的多边形要素。制度管控措施（Institutional Control, IC）属于非工程化管控手段，涵盖行政管控与法律管控措施，旨在最大限度降低污染物暴露风险，或保障修复行动的成果完整性。此类管控措施通常通过限制土地及资源使用，或提供可修正、引导场地内人类行为的相关信息来实现其功能。超级基金场地相关要素由地理空间专业人员与修复项目管理员（Remedial Program Managers, RPMs）组成的区域团队负责管理，SEGS 会每周采集区域数据，以更新全国数据集及要素服务。
