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.

Provides guidance and clarification regarding submission of certified decommissioning cost expenditure summaries following permanent plugging of any well, removal of any platform or other facility, clearance and verification of any site, and decommissioning of pipeline segments.

Remains Active past Expiration Date due to Continuing Resolution for Appropriations. The purpose of this NTL is to inform you that the Office of Natural Resources Revenue (ONRR) will collect inspection fees from you for FY 2016 as required by Division G, Section 107 of the Consolidated Appropriations Act, 2016 (Public Law 114-113), on behalf of the Bureau of Safety and Environmental Enforcement (BSEE).

ONRR will collect inspection fees from the designated operator of facilities above the waterline, excluding drilling rigs that were in place at the start of FY 2016. For drilling rigs (see definition), ONRR will collect inspection fees for all inspections completed during FY 2016, commencing on the first day of the Federal fiscal year (October 1, 2015). All subsea completions are counted as wells delivering production to a central facility and not as individual facilities requiring a separate inspection fee. Please note that ONRR has already invoiced the designated operators of facilities above the waterline, and for inspections of drilling rigs that have occurred through April 2016.

In addition, prior NTLs on this topic included a statement that structures in State waters that have bottom-founded wells in Federal waters are not subject to the inspection fee. Based on further review and interpretation of the appropriations language, this statement has been removed and the determination made that such structures are subject to the applicable inspection fees.

(COPAS). Specifically, BSEE requests that lessees rely on the COPAS guidelines (e.g. Classifications for Summary Form Billing© (MFI-26) and Joint Audit Data Exchange© (AG-26)) for reporting by cost classifications and/or examination of joint interest transactions as the primary framework upon which to submit the required information.
