7590-01 UNITED STATES NUCLEAR REGULATORY COMISSION DUKE POWER COMPANY, et al.
DOCKET NOS. 50-413'AND 50-414 ENVIRONMENTAL ASSESSMENT AND FINDING 0F NO SIGNIFICANT IMPACT i
The United States Nuclear Regulatory Consission (the ummission) is considering issuance of amendments to Duke Power Company, et al., (the licensee) for the Catawba Nuclear Station, Units 1 and 2, located in York County, South Carolina.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action: The proposed amendments would add operability.and surveillance requirements for radioactive liquid effluent monitoring-instrumentation for the turbine building sump. These requirements would provide a radioactive liquid waste sampling and analysis program for the 3
i demineralized sump water and its surveillance by radiation monitor EMF-31 before discharge into the Low Pressure Service Water System.
The Radwaste Treatment System (capacity 16,000 to 18,000 gallons per day) will remain the primary treatment system for processing highly contaminated j
wastes. The licensee proposes to install portable equipment to demineralize the larger volumes of slightly radioactive wastewater, 72,000 gallons per day or more, which can result from primary-to-secondary leaks in the steam generators. The turbine building sump also receives wastewater with very low levels of radioactivity from other sources such as floor drains and the auxiliary building drain sump. The treated wastewater would be discharged l
through radiation monitor EMF-31 into the effluent from the Low Pressure i
Service Water System.

The Need for the Proposed Action:
Primary to secondary leaks can develop through repairable defects in the steam generators and into the normally non-radioactive secondary side.
Such leaks wenld be repaired as they occur, q
but require continued unit operation with leakt;;a until the leak can be. fully i
identified and characterized. When these leaks occur, the turbine building.
sump can become radioactively contaminated.
The quality and quantity of this water may not be amenable to treatment in the Radwaste Treatment System because of the high volume or by the Conventional Waste Water Treatment System because of its inability to remove contaminants.
Therefore, the licensee plans to inso.11 portable equipment to process the slightly radioactive water. The proposed Technical Specifications would add operability and surveillance requirements for the processing equipment and instruments tion.
Environmental Impacts of the Proposed Action: The decision of whether the wastewater would be routed to the Radwaste Treatment System, the Conventional Wastewater Treatment System or the Low Pressure Service Water System would depend on the level of activity, anticipated volumes of sump effluent, anticipated volumes of liquid waste requiring processing through radwaste, and the need to process normal nonradioactive wastes.
Technical Specification 3/4.11.1, Table 4.11-1, already identifies the Conventional Wastewater Treatment System as a radioactive release point. All releases through this system and the Low Pressure Service Water System will be made in accordtoce with the Technical Specifications and will not result in
)
unacceptable concentrations of radioactive effluents released offsite.
Keither will there be any increased risk to public health and safety.
l.
The proposed amendments will not have any impact on the environment that has not already been reviewed and approved. Furthermore, they will not affect the current accident analysis assuriptions and will not cause an increase in radiological or non-radiological plant effluents, or occupational exposures, over what was previously considered.
Accordingly, Connission findings in the Final Environmental Statement P, elated to Operation of Catawba Nuclear Station, Units 1 and 2, dated January 1983 (NUREG-0921) regarding radiological and non-radiological releases from the plant during normal operation or after accidents are not adversely altered by this action.
Alternative to the Proposed Action: Since we have concluded that the environmental effects of the proposed action are negligible, any alternatives with equal or greater environmental impact need not be evaluated.
The principal alternative would be to deny the requested amendmants.
That alternative, in effect, is the same as the "no action" alternative.
That alternative would reduce environmental impacts of plant operation but would result in increased personnel radiation exposure during plant life.
Alternative Use of Resources: This action does not involve the use of resources not previously considered in connection wit' the Nuclear Regulatory Connission's Final Environmental Statement dated January 1983 (NUREG-0921) related to this facility.
Agencies and Persons Consulted: The NRC staff reviewed the licensee's request of June 12, 1987, as supplemented July 9,1987, January 8,1988, ar.d May 3, 1989. The NRC staff did not consult other agencies or persons.
Finding of No Significant Impact: The Connission has determined not to prepare an environmental impact statement for the proposed license amendments.

Based upon this environmental assessment, we conclude that the proposed action will not have a significant adverse effect on the quality of the human I
environment.
