C::mm:nwnith Edissa Mr. Benard C. Rusche August 20, 1976 Section 4.3, algal bloom 02 depletion, has been deleted because it was without scientific basis and did not incorporate basic principals concerning blue green algae and algal blooms.
Section 3.1.2.4 describes a monitoring program to identify algal problems if they should occur.
Section 5 has been abreviated to refer to Section 6 of Appendix A for administrative controls.
Section 5.8.1, Subsection F, has been changed to re-flect an increase in blowdown from 50,000 up to 500,000 GPM in accordance with a current agreement between Commonwealth Edison Company and the United States Environmental Protection Agency for NPDES Permit IL 0002224.
The proposed change has received on-site and off-site review.
