About NFLSS


The National Fluids Lease Sale System (NFLSS) supports BLM administration of the leasing program for Federal onshore oil and gas and geothermal leasing. Four key objectives of the new system are to: (1) provide efficiencies in the EOI submission process, (2) shorten the time required to prepare for an upcoming lease sale, (3) enable real-time reporting capabilities, and (4) extend protest management capabilities of the bureau.


This web-based system serves as a powerful and flexible assistant in the leasing workflow process. In addition to interfacing with the Legacy Rehost 2000 (LR2000) system and the available spatial applications, NFLSS will assist BLM state offices in managing pertinent surface use stipulations.


Key features of the NFLSS web application include:

  • Intuitive, user-friendly interface
  • Advanced search capabilities to provide rapid access to leasing data
  • Enhanced Reporting
  • Integration with existing bureau systems
  • Quick Links to Key BLM and DOI Resources
  • Role-based access control
  • Section 508 compliance
  • Robust Document Management capabilities that leverage metadata
  • New task management functionality
  • More transparency of leasing activities for the general public
  • Information Security
  • Central management of leasing data to facilitate reporting at the national level
  • Future integration with powerful GIS mapping tools.

The system is comprised of an internal web application, used by BLM staff, and a public-facing portal, which allows members of the public to submit expressions of interest (EOIs) and track EOIs through their lifecycle. Public users may use NFLSS to nominate land by submitting an Expression of Interest (EOI) via the online form. Internal users (who are authenticated) use the system to research and evaluate the availability of the land for leasing, as well as prepare for upcoming lease sales.


The new functionality that this system provides for the public user, as well as the BLM users that participate in business workflows, increases the efficiency of the leasing program and allows the bureau to provide better service to the public.


An integrated product team that provided critical input into the design of this system was comprised of representatives from several state offices, including California, Colorado, Eastern States, Utah, New Mexico, Montana, Nevada and Wyoming, Washington Offices 300; Washington Office 310; the BLM National Operations Center, Division of Information Resource Management; and a team of experienced application development team. The NFLSS project is the first software development project at BLM to employ Agile/scrum methodologies to rapidly produce application features that keep pace with the changing needs of the business.
