f Northem States Power Company 414 Nicollet Mall Minneapolis, Minnesota 55401 1927 Telephone (612) 330 5500 10 CPR Part 51 May 30, 1991 Director of Nuclear Reactor Regulatioi US Nucicar Regulatory Commission Attn:
Document Control Desk k'ashington DC 20555 MONTICELLO NUCLEAR GENERATING PLANT Docket No. 50 263 License No. DPR 22 Preparation of Monticello Nuclear Generating Plant's Environmental _ Report _Syp21ement Northern States Power Company is in the process of preparing an application for a renewed operating license for the Monticello Nuclear Generating Plant.
As part of this application, NSP will submit an Environmental Report Supplement to demonstrate that environmental impacts which may occur during the license renewal period have been assessed.
In connection with the issuance of the provisional operating Itcense for the Monticello Nuclear Plant, NSP submitted an Environmental Report to the Commission and based on the submitted information, the Commission issued a Final Environmental Statement in November of 1972.
Current NRC regulation requires that the NRC Staff prepare an Environmental Impact Statement or a supplement to the Final Environmental Statement in connection with the
" renewal of full power..
license to operate a nuclear power reactor
." 10 CFR Part 51 Section 51.20(b)(2).
Section 51.53(a) of the NRC's regulations requires "Each applicant for renewal of a license to operate a production or utilization facility covered by 10 CFR Section 51.20" to submit with its renewal application "a separate document, entitled
' Supplement to Applicant's Environmental Report Operating Licenso Stage.'"
The supplement to the Environmental Report is to:
"... discuss the same matters described in $$ 51.45, 51.51 and 51.52, but only to the extent that they differ from those discussed or reficet new information in addition to that discussed in the final environmental statement prepared by the Commission in connection with the construction permit."
In complying with the intent of these regulations, NSP is preparing an Environmental Report Supplement that will update the information presented in the Environmental Report and the Commission's 1972 Final Environmental Statament.
The Environmental Report Supplement will provide information developed subsequent to those documents and identify any discernible trends.
Predictions of effects to occur during the license extension period will also be made. k'here it is feasible. Information in existing documents will be referenced.

Northern States Power Company Director, NRR May 30, 1991 page 2 The Envirorutental Report Supplement that is being prepared will follow the general outline of the current NRC Regulatory Culde 4.2, Revision 2.
lloweve r,
since this guidance is directed at newly constructed nuclear plants which varies from the actlon of license rentwal, the content of the Environmental Report Supplement will vary from content guidance of Regulatory Guide 4.2. gi.es an outline of the cot; tent of what will be included in Monticello's Environmental Report Supplement.
Ve are aware that the Stafi is developing a generic Environmental Impact Statement that will seek to address many of the environmental issues that would otherwise be covered in plant specific Environmental Impact Statements for license renewal applications.
The generic Environmental Impact Statement would support changes to 10 CFR part 51 that would generically address various potential environmental lupacts associated with 11 cent.e renewal applications.
Because of the timing of the generic Environmental Impact Statement and its associated rulemaking, it is likely that the Monticello Environmental Report Supplement will be submitted af ter scheduled publication of the draf t generic Environmental Irtpact Statement but pri^r to publica' ion of the finni generic Envirorutental Impact Statement.
Several gencric topics that are likely to be covered in the generic Environmental Impact Statement would also fall within the scope of the Environmental Report Supplement.
Since the NRC Staff is preparing generic analyses of these issues, the Srpplemental Environmental Impact Statement may make use of these analyses even if the generic Environmental Impact Statement is not yet final when the Supplemental Environmental Impact Statement is issued.
We have reviewed our Environmental Ra art, the Final Environmental Statement, Regulatory Guide 4.2, and the proposed outline for the generic Enviroturental Impact Statement to identify issues for which the NRC Staff will likely have generic evaluations that would make Monticello specific analysis unnecessary.
These include 1.
Radiological health ef fects 2.
Severe accident analysis (Class 9 accidents) 3.
Severe accident mitigation design alternatives 4.
Transmission line impacts, including EMF, herbicides, etc.
5.
Uranium fuel cycle (Table S-3) 6.
Transportation of nuclear fuel and radioactive waste (Table S 4) 7.
Decommissioning impacts and costs

Director, NRR i4orthern States Power Company May 30, 1991 Page 3 8.
Alternatives Non generator alternatives (conservation, demand side management, rates, etc.)
Non conventional generation alternatives (solar, wind, biomass, etc.)
Conventional generation alternatives (coal, gas, oil, new nuclear)
Altctnative sites i
Facility and transmission design alternatives Since these issues are generic in nature (or, in the case of the alternatives, should be summarily disposed of on the generic basis that they are unreasonabic in the renewal context), we believe that it would be unnecessary and inefficient to include these issues in the Monticello Environmental Report Supplement.
There may be other issues included in the Genetic Envirotunental Impact Statement that will be handled by a generic conclusion on the impact for all affected plants.
These issues will be evaluated when the proposed Part 51 rule is published for comment August, 1991, to determine if Monticello's Environmental Report Supplement can take advantage of these generic findings.
If it is found that the findings of the Generic Environmental Impact Statement affect the contents of the Monticello Environmental Report Supplement, a
revision to the attached outline will be submitted.

May 30, 1991 Page 1-OUTLINE OF CONTENTS OF HONTICELIA'S ENVIRONMENTAL REPORT SUPPLEMENT IntroductioD This section will contain an explanation of the purpose of the Environmental Report Supplement including the need for license renewal.
It will also contain an explanaticn of the organization of the Environmental Report Supplement and the rationale fur the repos L content.
L Chapter 1: Need for Power from the Existing Facility This chapter will discuss the interrelationship between the Monticello j
facility, the NSP system, the-regional power requirements and consequences of not renewing the Monticello operating license for the incremental period.
i The discursion on the consequences of not renewing the Monticello operating license term will focus on power supply impacts to the system from a "no action" perspective.g L
Chapter 2: The Site and Environmental Interfaces Chapter 2 will present the relevant information concerning those physical, biological, and human. characteristics of the area environment that might be i
affected by the extension of the operating license and will concentrate on f
-updating _information in the original Environmental Report and Final Environmental Statement, particular attention will be given to the following subj ects :
l"
- Update the population distribution.
- Identify any changes in uses of adjacent lands and waters.
Update information on " threatened and endangered" plant and L
animal species and confirm existing ecological information, as I
appropriate.
. Update the meteorology data using currently available site specific data, including updated' joint frequency _ distribution data and appropriate period of diffusion and deposition L
paramoters.
l Verify if the hydrology and seismology information provided in j
the original Environmental Report is still appropriate for utilization in evaluating potential impacts.

Emphasis will be placed on demonstrating the continued operation of the station within the bounds of effects described in the original Environmental Report and currently established regulatory requirements.
The original Environmental Report and the Final Environmental Statement will be utilized to establish initial reference points for environmental effects projected to result fron initial station operation.
It will provide validation of any previous predictions of ef fects and updated predictions of the effect s of license renewal based on analysis of data collected and review of information generated during the period from the initiation of station operation until the present (or most recent data and information).
Discernible trends in effects will be identified.
Predictices of effects to occur during the license extension period will be made.
Particular attention is to be addressed to the following topics:
Description of the incremental cooling water system impacts since 1971.
Provide a description of plausible exposure pathways and calculation of dose rates to man and the environment with particular at.tention to those which contribute to significant exposures.
Present historical data and trends based on annual radiation doses to both onsite and offsite individuals.
