1461 122 Amendment No. 55
4.1-1 4.0 ENVIRONMENTAL SURVEILLANCE AND SPECIAL STUDIES 4.1 Biological 4.1.1 Aquatic objective 1.
To continue routine water quality determination in the Cedar River in order to identify any conditions which could result in environmental or water quality problems.
2.
To conduct physical, chemical and biological studies in and adjacent to the discharge canal and to compare the results with similar studies above the intake.
This will make it possible to determine any water quality changes occurring as the result of chemical additions or condenser passage and to identify any impact of the plant effluent on aquatic commun-ities adjacent to the discharge.
3.
To identify and quantify organisms impinged on the intake screens and entrained in the intake water in order to esti-mate the magnitude and effects of impingement and condenser passage on the ecology of the Cedar River.
4.
To verify the extent of the thermal plume.
Specifications Sampling sites will be established in the discharge canal and at four locations in the Cedar River (Figure 4.1-1) : 1) upstream of the plant at the Lewis Accesr Bridge; 2) directly above the plant intake;
- 3) at a point to be det rmined no more than 300' below the plant dis-charge; 4) adjacent to Comp Farm about 1/2 mile below the plant.
Deviations are permitted from the required sampling / analysis schedule if specimens are unobtainable due to hazardous conditions, equipment malfunction or laboratory accidents.
If due to equipment malfunction every effort shall be made to complete corrective action prior to the end of the next sampling period.
All deviations from the sampling /
analysis schedule shall be described in the annual report.
