Subject: Reclamation Invites Comments on Scope of Environmental Impact Statement (EIS) for
California's Proposed Quantification Settlement Agreement Activities and Other Related
Actions Including Implementation of an Inadvertent Overrun Policy on the Lower
Colorado River

Reclamation is preparing an EIS for activities that will allow the Secretary of the Interior (Secretary)
to execute an Implementation Agreement (IA) associated with a proposed Colorado River
Quantification Settlement Agreement among several California water agencies that hold contracts
with the Secretary for delivery oflower Colorado River water.

The EIS will describe the potential environmental impacts of Secretarial execution of an IA which
would result in the approval of water transfers that change the point of delivery of up to
approximately 400,000 acre-feet ofJower Colorado River water per year between California parties;
the implementation of biological conservation measures related to the water transfers; and
implementation of a 30-year lower Colorado River inadvertent overrun accounting and payback
policy.

The project area of the EIS will include the lower Colorado River and its 100-year floodplain
between Lake Mead and the southerly international boundary between the United States and Mexico.
The document will address effects in river flow between these two points that woUld occur from
Federal activities included in the proposed action and other related environmental consequences.

Indian tribes are invited to comment on the scope of the issues to be addressed in the EIS and to
identifY significant issues they believe are related to the proposed action. This invitation to comment
and participate in this process is pursuant to the Council on Environmental Quality Regulations for
Implementing the Procedural Provisions of the National Environmental Policy Act (40 CFR 1500-
1508, ~ 1501.7), the National Historic Preservation Act (Section 101{d){2) (16 U.S.c, ~ 470t), the
