UESTION 89 Provide an analysis evaluating the potential for adverse aquatic impacts due to increased site runoff and erosions from the laydown area and the construction of the storage building for the steam generators.
~Res onse The laydown area in which the Steam Generator Storage Compound (SGSC) will be located has an area of about 2 acres as shown in Figure 3. 1-2 of the Steam Generator Repair Report.
The area will be at elevation 17.5'ith side slopes of 1:3.
The area is located south and adjacent to the plant and is surrounded on the remaining three sides by the closed cycle circulating water cooling canals as shown in Figure 3. 1-2.
Runoff from the SGSC as well as from the adjacent ground, flows into the cooling canals, specifically Loch Rosetta and East Canal as shown on attached Bechtel Drawing No. 5177-28-C-8.
These canals flow into the. plant,intakes and the water is recirculated through the canal system after passing through the plant.
The canal system is closed-cycle and has no surface interaction with Biscayne Bay.
Any increased runoff from the laydown area will, therefore, not reach Biscayne Bay.
Furthermore, the increase in runoff is expected to be insignificant because of the small size of the SGSC/laydown area.
Therefore, there will
- beno effect of increased surface runoff from the SGSC/laydown area on aquatic life in Biscayne Bay and the effect of increased runoff on the cooling canals will be negligible.

UESTION ¹10 Provide an evaluation of the impact due to the increased onsite workforce on the site's sanitary waste treatment facility.
Indicate the potential for any aquatic impacts due to the increased sanitary effluents.
RESPONSE
As indicated in Section 6.3.l of the Steam Generator Repair Report, th repair activities will occur in areas that lack readily accessible sanitary facilities.
As a result, portable sanitary units will be utilized.
Since all sanitary wastes from the workforce will be removed from the site in the portable units, there will be no impact on waste treatment system.
e si e s san>tary UESTION ¹11 Indicate the kind, ultimate fate, and potentia1 for adverse aquatic impacts due to the use and disposal of any chemical cleaning compounds used during and related to the steam generator repair and installation of the demineralizer arid prior to station startup.
RESPONSE
~
1 The cleaning solutions which may be used are soap and water and/or Radiac solution (which is slightly acidic and thus will be neutralized prior to discharge to radwaste system) if necessary.
Both these solutions would if used, be processed by the radwaste system before discharge.

VESTION 812 Provide an evaluation of the non-radiological impacts due to the discharge of increased amounts of laundry waste water during the repair prog'ram..
Indicate the amount of laundry waste water that will be discharged daily, compare this discharge volume with the average discharge during normal operation, indicate the location of discharge, describe the manner in which the waste stream is treated, indicate its anticipated water quality and postulate its impact to the biota inhabiting the canal system.
RESPONSE
As indicated in the Steam Generator Repair Report, Sections 5.2.2.4 (dealing with radioactive liquid effluents), 6.3 and 6.3.2, the environmental impact of the laundering operation discharges during the repair effort is not considered significant because the number oP additional people required for repair (about 300) is typical of the number of additional people required for refueling and major maintenance activities associated with normal operation.
Although 22,000 gallons/day was the number used to estimate expected specific activities of the laundry waste water during the repair effort, it is expected that on the average only l0,000 gallons/day will be discharged.
