The Minerals Management Service issues Notices to Lessees
and Operators (NTLs) to formally provide clarification, description, or interpretation of a
regulation or OCS standard; provide guidelines on the
implementation of a special lease stipulation or regional
requirement; or provide a better understanding of the
scope and meaning of a regulation by explaining MMS
interpretation of a requirement.
We have listed the currently active NTLs that pertain to
offshore platforms and structures. We will update
the list as new structural related NTLs are issued,
expires, or are superceded. For active NTLs that
pertain to non-structural issues, please refer to the
MMS website.
To view the NTLs, simply click on the links provided in
the list. To download a PDF version of the NTL, see
our
download manager.
Letters to Lessees and Operators (LTL's) and Information
to Lessees and Operators (ITL's) 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 MMS
interpretation of a requirement.
The Minerals Management Service no longer issues Letters
to Lessees and Operators (LTL's). All notices are now in
the form of Notices to Lessees and Operators (NTL's). All
active LTL's will remain in effect until superseded or
rescinded.
Currently, there are no LTLs or ITLs that directly affect
structural issues for offshore platforms and structures.
