Underground Storage Tank Finder Application

The EPA recently developed the Underground Storage Tank (UST) Finder application (hereafter UST Finder). UST Finder is a publicly available web map application containing a comprehensive, state- sourced national map of UST and leaking underground storage tank (LUST) data. UST Finder is available via EPAs GeoPlatform at https:// gispub.epa.gov/ustfinder. UST Finder provides users access to information on the attributes and locations of active and closed USTs, UST facilities, and LUSTs in states in a geographic information system (GIS) environment. This information collection relates to information that state and territorial agencies already collect from UST and LUST owners and operators as part of their customary business practice to manage their compliance and enforcement programs. To successfully implement, maintain, and improve the data quality and usability of UST Finder, the Agency seeks to gather, on a voluntary basis, information from state and territorial agencies that oversee UST/LUST programs. Specifically, EPA will request that these agencies provide location and other relevant data about USTs and LUSTs that is already being collected and managed by states and territories. This information collection is voluntary and does not require the agencies to collect additional data on USTs/LUSTs beyond the data elements that are already being collected through their previously implemented programs. States and territories will decide the extent of information to be provided. The EPA intends to implement four options for collecting the UST/LUST data from states and territories: (1) by developing an Exchange server or other automated service through which states can push their data to the EPA, (2) by developing a link to the agencies pre-existing electronic service used to maintain public websites such that the EPA can pull the data, (3) by allowing states and territories to submit existing databases or spreadsheets through an approved file sharing method, or (4) by EPA obtaining publicly available data from state and territory public agency websites (an option that will be exercised if states and territories do not voluntarily submit their data). For all data transfer options, the EPA will standardize, curate, and enter records into the UST Finder application.
