Scenic areas. The Corps has previously stated that any revision of the SMP will require the completion of a Supplemental Environmental Impact Statement (SEIS) for the entire Lake Texoma project that will consider the cumulative impacts of the extensive development that has occurred around the Lake since the original EIS was conducted in the 1970s. Completion of a lake-wde SEIS has been estimated by the Corps to take up to 2 years to complete at a cost of approximately $2.5 million. Since Section 3182(j) contained no provisions exempting the sale from the requirements of NEPA, it is expected that completion of the SEIS and revision of the SMP will also be required prior to completion of the sale, and that the city of Denison will be required to bear that as a cost associated with the transaction.
