Response
The Palisades Plant emergency procedures have been reviewed to assure that a),

As a result of the review, five new emergency procedures were created to specifically address the control of the plant following loss of power to Class 1-E and Non-class 1-E instrumentation and control buses (preferred AC buses Y-10, Y-20, Y-30 and Y-40 and instrument AC bus Y-01).
These new procedures (Off-Normal Procedures ONP 24.1 - 24.5) are avail-able at the site for inspection and will be implemented prior to startup.
