Chukchi Sea Planning Area Oil and Gas Lease Sale 193
OCS EIS/EA BOEMRE 2010-0034
Revised Draft Supplemental Environmental Impact Statement
This Revised Draft Supplemental Environmental Impact Statement (EIS) addresses Outer Continental Shelf (OCS) Oil and Gas Lease Sale 193, Chukchi Sea, Alaska. The Draft SEIS augmented the analysis in the 193 Final EIS by analyzing the environmental impact of natural gas development and evaluating incomplete, missing, or unavailable information pursuant to 40 CFR 1502.22 (Appendix A) to respond to the Court's remand.
A Draft SEIS was made available to the public on October 15, 2010, and a 45-day public review and comment period commenced. Many commenters requested that BOEMRE perform an analysis that takes into account the possibility of a blowout during exploration activities, in view of the Deepwater Horizon event. In March 2011, BOEMRE announced a Very Large Oil Spill (VLOS) analysis would be included the SEIS. The analysis was completed and integrated within this Revised Draft SEIS.
The Revised Draft SEIS relies on the existing analysis provided by the 193 FEIS where appropriate, adds: (1) new analysis on environmental impact of natural gas development, (2) evaluates incomplete, missing, or unavailable information pursuant to 40 CFR 1502.22 (Appendix A), and (3) analyzes a hypothetical VLOS scenario. The Revised Draft SEIS also includes revisions in light of comments received on the Draft SEIS and analyzes additional information which has become available since the publication of the 193 Final EIS.
A Notice of Availability (NOA) announcing the Revised Draft SEIS was published in the Federal Register on May 27, 2011. Publication of the NOA commenced a 45-day public comment period. BOEMRE will accept public comments through July 11, 2011.
