Accordingly, BOEM has determined that'it is necessary to require .the provision of supplemental bonding (additional security), pursuant to 30 CFR § 550.1011, to assure performance of obligations .associated with rights-of-way for which W&T is the holder-of-record.

Utilizing its authority under 30 CFR § 550.1011(a)(2), BOEM hereby orders W&T to provide additional security in the amount of $58,539,836, under the terms set forth in this Order, for the rights-of-way for which W&T is the holder-of-record. Those rights-of-way are listed in the Appendix attached to this Order.

BOEM hereby orders W&T to submit the required additional security of $58,539,836 to BOEM's Leasing & Financial Responsibility Section prior to 5:00 p.m. Central Time on March 29, 2016.

BOEM also hereby notifies W&T that the agreement, referred to as a Financial Assurance Plan, entered into between W&T and BOEM on December 21, 2015 is no longer ih effect, due to W&T's failure to comply with the agreement. Pursuant to the agreement, W&T committed to providing additional security in installments, with the first installment of $69,998,478 due on January 20, 2016. As of today's date, W&T has provided only $7,010,164 of that first installment due on January 20, 2016. W & T has failed to fulfill its commitments under the agreement and failed to provide the agreed-to additional security.

W&T may submit responses to this Order on-line at https://timsweb.bsee.gov, or by mail to, Leasing & Financial Responsibility Section, GM 266A, Gulf of Mexico OCS Region, 1201 Elmwood Park Boulevard, New Orleans, Louisiana 70123.

The BOEM Gulf of Mexico Region (GOMR) reserves the right to amend this Order based on information that leads BOEM to determine that a different amount of additional security is required, including any changes in decommissioning cost estimates provided to BOEM by the Bureau of Safety and Environmental Enforcement, Gulf of Mexico Region.
