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.

Under Section (b)(7) of 43 U.S.C 1337 (Section 8(b)(7) of the OCS Lands Act, as amended), each offshore lease issued after September 18, 1978, has a 20 percent small refiner offer provision. Under this provision, lessees must offer small or independent refiners 20 percent of the crude oil, condensate, and natural gas liquids produced on each lease, at the market value and point of delivery applicable to Federal royalty oil. This 20 percent set aside is in addition to the amounts available under the Federal royalty oil program.
