Miscellaneous 100.0 100.1.
In addition to responses to other specifically requested information, provide L(Nons) a summary and brief discussion :n table form, by section, of differences between currently projected environmental effects of the nuclear power station (i,ncluding those that would degrade and those that would enhance environmental conditions) and the effects ' discussed in the environmental report submitteo at the construction stage.
290.0 Terrestrial Resources 290.1 Have a State of Illinois endangered species specialist or plant systematist (2.2) confirm the identification of Geum rivale (Purple Avens) as this species
.is lui the Illinois State endangered s'pecies list.

- (3.9.5) and other metallic objects beneath the Byron transmission lines using the 5.0 milliamperes vertical clearance criterion of the National Electric Safety Code,1977 edition.
Terrestrial Resources - Noisc At the site visit, Commonwealth Edison Company representatives indicated 290.~a
-(2.7) that the Byron site boundary has changed from that shown in the ER-OL, due, at least in part, to cooling tower. noise attenuation.
Indicate clearly on 4
-7 a mao of suitable scale the present site boundaries and the relationship of these boundaries to plant operational noise sources end nearby offsite noise sensitive land uses (e.g., residences, churches, cemeteries, schools, parks).
Indicate how the identified noise sensitive land uses were considered in determining the new site boundaries.
- 290.4 Indicate how often and now long the mechanical draft cooling towers on-site (5.6) are expected to operata du.ing normal plant operation.

Identify the latest scheduled commercial operating dates for Byron 1

and Byron 2.
320.2.
Where applicable, all tables in Chapter 1 should be revised to show actual value@
for relevant variables for the years 1978,1979, and 1980 and should be extended to provide estimated values for the five-year period following the date of initial operation for Byron 2.
320 3.
For the year 1980 provide (a) a breakdown of electric energy generated by fuel type (coal, nuclear, etc.) and (b) the average production cost (fuel and 0&M) by fuel type.
Identify any availability problems you anticipate in the forseeable future with respect to any of the fuels on which you currently depend.
320.4.
Quantify, if possible, the expected effect of Byron 1 & 2 on base load consumption of coal and oil.
320.5.
Provide the most recent estimates of the capital cost for Byron 1 & 2, separating the cost by unit.
Indicate the proportion of the estimated capital costs which has been spent.
320.6.
For the first year of commercial operation for each unit provide estimates of the total generating costs and of each component of the costs (fixed charges, fuel, 0 & M, other) both in mills /kwh and in dollars.
320.7.
Provide new estimates, if any, of decommissioning and dismantling costs.
320.8.
Provide the following:
A production cost analysis which shows the difference in system production costs associated with the availability vs. unavailability of the proposed nuclear addition.
Note, the resulting cost differential should be limited solely to the variable or incremental costs associated with generating electricity from the proposed nuclear addition and the sources of replacement energy.
If, in your analysis, other factors influence the cost differential, explain in detail.
The analysis should provide results on an annual basis covering a.
the period from initial operation of the first unit through five full years of operation of the last unit.
d-b.
The analysis should assume electrical energy demand gre-s at (1) the system's latest official forecasted growth rate, and (2) zero growth from latest actual annual energy demand.
All underlying assumptions should be explicitly identified and c.
explained.
d.
For each year (and for each growth rate scenario) the following results should be clearly stated:
(1) system production costs with the proposed nuclear addition available as scheduled; (2) system production costs without the proposed nuclear addition available; (3) the capacity factor assumed for the nuclear ad-dition; (4) the average fuel cost and variable 0 & M for the nuclear addition and the sources of replacement energy (by fuel type) - both expressed in mills per kWh; and (5) the proportion of rdplacement energy assumed tc be provided by coal, oil, gas, etc.
