EPA Facility Registry Service - National Pollutant Discharge Elimination System Sites (NPDES)

Overview This publicly available FRS data is part of the FRS Sub Facility map service and has been created for ESRI Living Atlas. The Sub facility map service is comprised of the EPA National Pollutant Discharge Elimination Systems Sites (NPDES), authorized by the Clean Water Act by regulating point sources that discharge pollutants into the waters of the United States. The NPDES data set provides outfall locations (or discharge points) of various pollutants into water systems from facilities being monitored by the EPA. The Facility Registry Service (FRS) provides quality facility data to support EPA's mission of protecting human health and the environment by identifying and geospatially locating facilities, sites, or places subject to environmental regulations of environmental interest. Facility data is improved with geospatial processing of incoming data and data curation tools to provide an integrated, dataset to partners and the public through a variety of methods and products. For more detailed information about these facilities, use the FRS Query tool. Feature Layer FRS Interests NPDES: This primary layer contains detailed site-level data including the facility name, location address, city, county, and state codes, along with geographic coordinates standardized to the NAD83 datum. It also includes federal and regional EPA identifiers, environmental interest types related to NPDES permits, program system IDs, and web links to EPA resources for more detailed facility and program information. The data also captures information about the collection and accuracy of location data, activity status of permits, as well as indicators related to public access and federal land ownership. Geographic Coverage The data covers facilities regulated under the NPDES program throughout the United States and its territories. Locations include urban and rural settings, with coverage extending across all U.S. EPA regions, counties, and hydrologic units as identified by federal standards. Use Cases Tracking and managing regulatory compliance of water pollutant discharges. Supporting environmental research and watershed management efforts. Providing public access to information about regulated facilities and their environmental permits. Assisting policymakers and regulators in decision-making related to water quality and pollution control. Data Access and Licensing This dataset is produced by the U.S. EPA and is in the public domain, available for unrestricted use. Users are encouraged to consult associated metadata for data limitations and intended use guidance.概述 本公开可用的设施注册服务（Facility Registry Service, FRS）数据集隶属于FRS子设施地图服务，专为ESRI生活地图集（ESRI Living Atlas）打造。该子设施地图服务涵盖美国环境保护署（U.S. Environmental Protection Agency, EPA）依据《清洁水法》（Clean Water Act）通过管控向美国水体排放污染物的点源所设立的国家污染物排放消除系统站点（National Pollutant Discharge Elimination Systems, NPDES）。NPDES数据集提供了受EPA监管的各类设施向水体排放污染物的排污口位置（或称排放点）信息。 设施注册服务（FRS）可提供高质量的设施数据，通过识别并空间定位受环境监管或具有环境关注度的设施、场地或场所，助力EPA达成保护人类健康与环境的使命。通过对传入数据开展空间处理并借助数据治理工具优化设施数据，最终可通过多种方式与产品向合作方及公众提供整合后的统一数据集。如需获取这些设施的详细信息，请使用FRS查询工具。 要素图层：FRS关注NPDES 本核心图层包含详细的场地级数据，涵盖设施名称、位置地址、城市、郡县及州级代码，以及采用NAD83基准面标准化处理的地理坐标。此外还包含联邦与区域级EPA标识符、与NPDES许可相关的环境关注度类型、项目系统ID，以及指向EPA资源的网页链接，用于获取设施与项目的详细信息。该数据集还收录了位置数据的采集与精度信息、许可的活动状态，以及与公共访问权限和联邦土地所有权相关的各类指标。 地理覆盖范围 本数据集覆盖全美及海外领地内受NPDES项目监管的所有设施。数据涵盖城市与乡村场景，覆盖范围遍及美国EPA所有辖区、郡县及联邦标准界定的水文单元。 应用场景 用于追踪与管理水污染物排放的监管合规情况；支撑环境研究与流域管理工作；向公众开放受监管设施及其环境许可的相关信息；协助政策制定者与监管机构开展与水质及污染防控相关的决策工作。 数据获取与许可 本数据集由美国EPA编制，属于公共领域资源，可无限制使用。建议用户查阅关联元数据以了解数据局限性与预期使用指南。
