Volume of the net flow to the receiving waters required for
dilution to reach established water quality standards must
be determined on the basis of daily discharge and converted
to either surface area or miles of shore based on cross
section and annual minimum flow. Present user density for
the locality must be obtained. This permits estimation of
lost user days on an annual basis.

Total chemical effect on aquatic biota should be estimated.
Biota in dilution water should be considered in calculations
if applicable as well as biota affected by discharge.
Supporting documentation should include reference to
applicable standards, chemicals discharged, and their
lethality for the aquatic populations affected.

The volume of water required to dilute each chemical to
meet applicable water quality standards should be
calculated. The ratio of this volume to the yearly minimum
net flow, where applicable, of the receiving waters should
be expressed as a percentage, and the largest such
percentage reported. Report the total solids if this is a
limiting factor. Include in this calculation the blowdown
from cooling towers.

Where downstream users withdraw drinking water supplies
from the affected water body, lost water to users should be
estimated.

Where downstream users withdraw irrigation water, this loss
should be evaluated as the sum of two volumes: the volume
of the water lost to downstream agricultural users and the
volume of dilution water required to reduce concentrations
of dissolved solids in remaining water to an agriculturally
acceptable level.

The actual concentration of each pollutant in ppm for
maximum daily emission rate should be expressed as a
percentage of the applicable air quality standard. Report
the maximum percentage.

A statement must be made as to whether odor originating
in plant is perceptible at any point off-site.

Water lost to household use must be estimated for areas
where water now supplied from wells would fail to meet
applicable drinking water quality standards (calculated
from average annual salt deposition and rainfall).

*Applicant may substitute an alternative unit of measure, where appropriate. Such a measure should be applied consistently to all alternatives for the effect being measured,

Salt tolerance of local affected area vegetation must be
determined. That area, if any, receiving salt deposition in
excess of tolerance after allowance for dilution by local
rainfall must be determined. Report separately an
appropriate tabulation of acreage by land use. Specify such
uses as recreational, agricultural and residential.

If salt spray impinges upon a local community, then
property damage may be estimated by applying to the local
value of buildings, machinery, and vehicles a differential in
average depreciation rates between this and a comparable
sea-coast community, to obtain an estimate of annual
losses.

AEC AMENDMENT TO APPENDIX D TO PART 50

TITLE 10-ATOMIC ENERGY

CHAPTER 1-ATOMIC ENERGY COMMISSION

PART 50-LICENSING OF PRODUCTION AND UTILIZATION FACILITIES

Implementation of the National Environmental Policy Act of 1969

[graphic]

On September 9, 1971, the Atomic Energy Commission published in the FEDERAL REGISTER (36 F.R. 18071) a revision of Appendix D of its regulation in 10 CFR Part 50, effective on publication. Revised Appendix D as published is an interim statement of Commission policy and procedure for the implementation of the National Environmental Policy Act of 1969 (NEPA) in accordance with the decision of the U.S. Court of Appeals for the District of Columbia Circuit in "Calvert Cliffs' Coordinating Committee, Inc., et al. v. United States Atomic Energy Commission, et al.", Nos. 24,839 and 24,871. The procedures in Appendix D apply to licensing proceedings for nuclear power reactors; testing facilities; fuel reprocessing plants; and other production and utilization facilities whose construction or operation may be determined by the Commission to have a significant impact on the environment. The procedures also apply to proceedings involving certain specified activities subject to materials licensing.

RULES AND REGULATIONS

The Commission adopted certain minor amendments to revised Appendix D, published in the FEDERAL REGISTER on September 30, 1971, and November 11, 1971.

The Commission has adopted additional amendments to revised Appendix I relating to the procedures for publishing notices of hearing or opportunity for hearing with respect to proceedings subject to sections B, C, and D.

Those sections deal respectively with procedures applicable to cer tain facility and materials licenses issued during the period from January 1, 1970, the date of enactment of NEPA, to September 9, 1971, with the procedures applicable to construction permits for certain facilities issued prior to January 1, 1970, for which operating licenses or notice of opportunity for hearing on operating license applications have not been issued, and with procedures applicable to pending hearings and hearings to be noticed in the near future.

Under section B, section C, and section D.3 presently in effect, notices of hearing or opportunity for hearing in the licensing proceedings subject to those sections could not be published until the final detailed statement or supplemental detailed statement had been pre
