Notice to Lessees (NTLs)

Notices to Lessees and Operators (NTLs) are formal documents that provide clarification, description, or interpretation of a regulation or OCS standard; provide guidelines on the implementation of a special lease stipulation or regional requirement; provide a better understanding of the scope and meaning of a regulation by explaining BSEE interpretation of a requirement; or transmit administrative information such as current telephone listings and a change in BSEE personnel or office address. Letters to Lessees and Operators (LTLs) and Information to Lessees and Operators (ITLs) are also formal documents that provide additional information and clarification, or interpretation of a regulation, OCS standard, or regional requirement, or provide a better understanding of the scope and meaning of a regulation by explaining BSEE interpretation of a requirement.

On April 27, 2016, the Bureau of Safety and Environmental Enforcement (BSEE) issued Notice to Lessees and Operators (NTL) No. 2016-N03, Reporting Requirements for Decommissioning Expenditures on the OCS, to provide guidance and clarification regarding regulatory requirements pertaining to the submission of certified decommissioning expenditure summaries following the permanent plugging of any well, removal of any platform or other facility, and clearance and verification of any site. BSEE amended its regulations addressing decommissioning expenditure reporting, effective December 16, 2016, by including requirements for the submittal of certified summaries of decommissioning expenditures for right-of-way (ROW) and lease term pipelines. The additional requirements concerning the submission of certified decommissioning expenditures summaries are found at 30 CFR 250.1704(i).1 As a practical matter, BSEE recognizes, and prefers, that the operator submit the required summary of decommissioning costs on behalf of the lessees, the owners of operating rights, or the pipeline ROW holders. The summaries must be submitted within 120 days after completion of each decommissioning activity.
