water rights on Colorado River System tributaries within the Contractor's state if
there is documentation that the water rights have been used for a significant period
of Years and that the water rights were perfected prior to June 25, 1929 (the

Tributary Conservation DSS introduced to the Mainstream shall be subject to
verification by the Secretary as provided in Section 4.D. Tributary Conservation
DSS may be delivered for Domestic Use only.
2. Imported DSS

with the Secretary, contractual or otherwise, to ensure no interference with the
Secretary's management of Colorado River System reservoirs and regulatory
structures. Any arrangement shall provide that the Contractor must obtain
appropriate permits or other authorizations required by state and federal law. The
actual amount of any Imported DSS introduced to the Mainstream shall be subject
to verification by the Secretary as provided in Section 4.D.
B. Creation of DSS
A Contractor may only create DSS in accordance with the following conditions:
A Contractor shall submit a plan for the creation of DSS to the Secretary
demonstrating how all requirements of these Guidelines will be met in the
Contractor's creation of DSS. Until such plan is reviewed and approved by the
Secretary, subject to such environmental compliance as may be required, such
plan, or any DSS purportedly created through it, shall not be a basis for creation
of DSS. A DSS plan will consist of at a minimum the following information:
a. Project description, including what extraordinary measures will be taken to
conserve or import water;
b. Term of the activity;
