station. operational effects from macro-regional effects. Since the. Branch Technical Position recomends monitoring'of. radioiodines.'and particulate J
l at one or-more control. locations, this'. change is 'a'cceptable.;
With regard to monitoring radionuclides in water,-SCE&G isccurrently re-
..1 quired-to monitor. surface water, ground water, and drinking water.; Although there are indicator.and control samples taken for surface water and ground water, only an indicator) sample is taken'.for monitoring drinking water; u
The nearest indicator location for monitoring public ' drinking ' water is -
~1ocated at the Columbia Water Works which is.about 25 miles. downstream of' a
the plant's liquid. effluent discharge point-(Ref.1).
SCE&G 3roposes to; j
add a control'1ocation for monitoring drinking water. This c iange is d
~
acceptable.
With regard to monitoring radionuclides in: vegetation. Sumer's Technical,
3 Specifications. currently. require that ~3 broadleaf samples;bettaken from.3 i
indicator. locations where the' highest concentrations of ~ radionuclides are -
1 i:
l expected.. SCE&G proposes to reduce the number of indicator: locations from.
three to_two. The present. food products requirement is. compensatory.in l
nature due. to the lack of dairy within five miles. The two remaining indicator locations' have consistently remained the' highest relative deposition locations and have better-potential; for determining any.offsite exposures as indicated by the. annual land'use. census and meteorological-monitoring activities conducted since 1978. Therefore :this change is u
acceptable.
The staff has reviewed the proposed changes to Technical:Sp'ecifications; for the Virgil C. Sumer Nuclear Station, and finds ~ that'the proposed changes meet the applicable regulatory guidance and requirements and are,.
therefore, acceptable.
- 3.0 ENVIRONMENTAL. CONSIDERATION This amendment involves a change'in surveillance requirements.
The staff has determined that the amendment involves.no significant-increase in the' amounts, and no significant cht.nge'in the types, of.
any effluents that may be released offsite, and 'that there;is' no-j significant increase in individual or cumulative occupational radi-ation exposure. The Comission has previously issued a proposed finding that this amendment _ involves no significant. hazards consid-eration, and there has: been no public.coment'on_-such finding.-
Accordingly, this amendment meets the eligibility criteria:
for categorical exclusion set'forth in.10 CFR Section 51.22(c)(9).
Pursuant to-10 CFR 51.22(b) no. environmental; impact statement orc environmental assessment need be prepared in' connection with the' issuance of this amendment.-

4.0 CONCLUSION
f The Commission made a proposed determination that this amendment iiivolves
}
no significant hazards consideration which was published in the Federal i
Register on July 29, 1987 (52 FR 28387) and consulted with the State of South Carolina. No public comments or recuests. for hearing.were received, and the State of South Carolina dic not have any. comments.
We have concluded, based on the considerations discussed above,
)
that:
(1) there is reasonable assurance that the health and safety of.the public will not be-endangered by operation in the l
proposed manner,.and (2) such activities will be conducted;in
'j compliance with the Commission's regulations and the issuance of l
this amendment will not be inimical to the common' defense and security.or to the health and safety of the public.
