United States, Public notice of which was issued on February 13, 1981.
The applicat's mailing address.is: Arkansas Power & Light Company . ,
l P.O. Box 551 -
Little Rock, Arkansas 72203 The discharge is.made into Dardanelle Reservoir, a water of the United States which is suitabic for primary contact recreation, propagation of desirable species of fish, wildlife and other aquatic life; raw water sour-ces of public water supplies; and other compatible uses and is located va that water at the Arkansas Nuclear One Steam Electric Station on Lake Dardanelle, near Russellville, Pope Cocnty, Arkansas. A fact sheet is available. The applicant's activities, under the standard industrial classification (SIC) code 4911 which result in the existing discharge are the ger.eration of electrial power for transmission and sale.
The changes from the heretofore issued authorization to discharge wastewater are:
- 1. Effective July 1,1984 no discharge of total residual chlorine is allowed from Outf all 001, once-through cooling water. .
- 2. Effective July 1,1984 chlorine discharge from Outfall 002, cooling tower blowdown, is limited to 0.14 mg/l total residual chlorine.
