2600 Bull Street Columbia, S.C. 29201 OcMber 7,1982 Dr. Kahtan N. Jabbour Pro.fect Manager Division of Licensing Office of Nuc1 car Reactor Regulation U.S. Nuclear Rcquiatory Commission Washington, D.C. 20555 RE: Draft Environmental Impact Statement Catawba Nuclear Station, Units 1 & 2 Docket Nos. 50-413 and 50-414 Duke Power Company, et.al.

Dear Dr. Jabbourt We have reviewed this Draft Environmental Statement and offer the following comments on its content ' '

Section 5.3.2.2, Surface Waters, discusses the impacts of heated water discharges on Lake Wylie and the National Pollutant Discharge Elimination System permit issued by DHEC for the discharge. Page 5-4, paragraph 1, indicates that certain portions of Lake iiglie would violate State water quality standards due to heated water discharges. This is not the case.

Section C-7 of Regulation 61-68, Water Classification-Standards System for the State of South Carolina, allows establishment of mixing zones for thermal discharges on a case-by-case basis. During the NPDES revicw for the Catawba Station, the effects of the thermal discharges were noted, and while no formal mixing zone delineations were made in the permit, the modelling information supplied by Duke Power Company was cons)dered sufficient and the area impacted by the discharge consistent with the State's mixing zone policy. Therefore, we recommend tnat the second sentence in the first full paragraph on page 5-4 he reworded as follows: "Thus, the areas given above for the station under worse-case and average conditions represent the areas of Lake Wylia that are considered mixing zones which are allowed by the South Carolina State regulations."

Dr. Kahtan N. Jabbour October 7, 1982 Page Two Additionally we feel that sentences 4 and S in the same paragraph should be reworded as follows:

"The pc. 'it does not specifically limit the station dischargo temperature during operation nor delineate specific mixing zones since the station design, con-sisting of a closed cycle cooling system with

• cold side blowdown * (diversion of blowdown at a point in the flow path beyond passage through the cooling towers),

will tend to minimite discharge of heated water from the facility."

Mtion S.9.4.5, Accident Risk and Impact Assessmento Number 5, ,

Releas ts to Groundwater, page 5-42, states thato "There would be one ma, a municipal water user affectsd by contamination of the Catawba River a tem." We feel that this statement is incorrect and that more informa . an needs to be included regarding downstream water users. There are currently a number of users, both industrial and municipal, which

^

are considered major water users by DHEC's Bureau of Water Supply. Also r the City of Rock Hille South Carolinar is presently in the process of obtaining necessary approvals to construct a major drinking water intake structure in Lake Wyller downstream fzom the Catawba Plant. I am attaching a list of water users, in downstream order, that could be impacted by an accident at the plant and request that you include this information as part of the final onvironmental statement.

Page S-42. paragraph 4 also states that the City of Charleston, a South Carolina " draws about 10% of its water from Lake Moultrie." This r

is incorrect. Charleston currently withdraws water from the Edisto River.

i Construction is underway to allow the City to withdraw water from the Back River Reservoir which receives water from the Cooper River below Lake Moultrie via Durham Canal. While some of the water to be utilized by Charleston according to their future plans will have been discharged from Lake Moultrie the City of Charleston has no intake in the lake itself.

r Thank you for the opportunity to coment on this draft environmental statement. I trust our comments and suggestions will be included in the final environmental statement to be issued for the project. If you have any questions concezning these comments, please contact me at (803) 758-5496.
