Attachment I provides responses to the Ohio EPA questionnaire entitled " Reporting 1
and Testing Requirements for Cooling Water System Additives".- The proposed routing of molluscicide is shown in Attachment 2. Water systems will be treated 2 to 3 times between June and November at a concentration of between 15 and 20 mg/l for 6 to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

1.
The name of the additive.
The additive is " Clam-Trol CT-1" (Bet: Industrial).
2.
The concentration (mg/I) of the additive to be used.
Additive concentrations will be between 15 and 20 mg/l for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> la the June and August treatments, and 10 to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for the October / November treatment.
3.
The expected concentration of the additive c aed in the discharge or blowdown i
immediately prior to entering state surface water.
Zero discharge (0.0 mg/l) of the molluscicide will be achieved by adsorption onto bestonite clay added to the discharge prior to entry to Lake Erie.
4.
The flowrate (mad) of the discharge to state surface water.
The average flowrate for 1939 was g6.2 mad.
5.
