EPA Facility Registry Service - Toxic Release Inventory (TRI) Sites

Overview This layer provides facility information for the Toxic Release Inventory (TRI). TRI is EPA's publicly available database that contains more than 650 toxic chemicals that are being used by industry groups and federal facilities, manufactured, treated, transported, or released into the environment. For more information on TRI and TRI facilities, visit theTRI Search tool. 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. Geographic Coverage The data encompasses facility locations throughout the United States, including territories and tribal areas. Use Cases and Applications Supports environmental regulators and policymakers in monitoring toxic chemical releases and compliance with environmental laws. Assists researchers and the public in identifying and understanding facilities involved in chemical manufacturing and release activities. Enables geospatial analysis for environmental impact assessments, emergency response planning, and community health studies. Data Source and Licensing This Feature Service is maintained by the EPA FRS Support team and is based on data from the EPA's national environmental program for the Toxic Release Inventory. Data is updated regularly, ensuring current information is available. The dataset is in the U.S. public domain, freely accessible for use under the U.S. Government public domain status, with no warranty on accuracy or suitability.### 概览 本图层提供有毒物质排放清单（Toxic Release Inventory, TRI）的设施信息。TRI是美国环境保护署（Environmental Protection Agency, EPA）的公开数据库，收录超过650种有毒化学品，涵盖行业团体与联邦设施使用、生产、处理、运输或排放至环境中的相关数据。如需了解TRI及TRI设施的更多信息，请访问TRI查询工具。 设施登记服务（Facility Registry Service, FRS）旨在通过识别并空间定位受环境法规约束或具有环境关注度的设施、场地或场所，为EPA保护人类健康与环境的使命提供高质量设施数据。通过对传入数据开展空间处理及数据整理工具优化设施数据，以多种方式与产品向合作方及公众提供整合后的数据集。如需了解这些设施的详细信息，请使用FRS查询工具。 ### 地理覆盖范围 本数据集涵盖全美范围内的设施点位，包括海外领地与部落区域。 ### 应用场景 可为环境监管者与政策制定者提供有毒化学品排放监测及环境法规合规性监管支持；协助研究人员与公众识别并了解参与化学品制造与排放活动的设施；可支撑环境影响评估、应急响应规划及社区健康研究等领域的空间分析工作。 ### 数据来源与授权 本要素服务由EPA FRS支持团队维护，数据基于EPA国家有毒物质排放清单环境项目的相关资料。数据集定期更新，以保障信息的时效性。本数据集属于美国公共领域，可依据美国政府公共领域条款免费使用，不对其准确性或适用性提供任何担保。
