Exhibit C Master Tank List RF 115-25.xlsx

This file is a comprehensive Excel spreadsheet detailing Underground Storage Tank (UST) and Aboveground Storage Tank (AST) inventory for the Massachusetts Bay Transportation Authority (MBTA), covering multiple bus garages, subway stations, and maintenance facilities across greater Boston. The document provides an extensive inventory of tanks across locations including Albany, Boston, Charlestown, Everett, Lynn, Quincy, and other municipalities, with detailed information on each tank's specifications, status, contents, installation dates, and technical characteristics. The tanks primarily serve bus and subway maintenance facilities, storing various substances such as diesel fuel, motor oil, waste oil, antifreeze, transmission fluid, and backup generator fuel.

The spreadsheet contains critical technical details for each tank, including tank name, facility type, tank status (in use or temporarily closed), contents, capacity (ranging from 60 to 75,000 gallons), tank material (steel, FRP, poly), installation and potential removal dates, monitoring methods (interstitial monitoring, exempt), and specific site identifiers. Additional technical specifications include tank construction type, manifolding details, spill bucket information, overfill protection, line material, dispensing type, and compliance tracking metrics such as monthly monitoring, periodic inspections, inventory reconciliation, and annual compliance testing. The document appears to be part of a comprehensive asset management and regulatory compliance tracking system for the MBTA's infrastructure.
