CG&E RESPONSE TO'NRC REQUEST FOR ADDITIONAL INFORMATION FOR.

ENVIRONMENTAL REVIEW OF APPLICANT'S REQUEST TO WITHDRAW THE ZIMMER OL APPLICATION Question 1:

' Provide a site plan showing' areas (including transmission corridors) disturbed by construction-related activities. Identify

_the, specific use of each. disturbed area. Estimate acreage for each such disturbed area.

' Pesponse

'A site plan as of January 21,1984 (announced decision to convert

~ , the. Zimmer Station to coal) is shown on Figures 1 and 2. The plan identifies all temporary construction office facilities, craft trailers, tool trailers, sanitary facilities and permanent construction complexes, shops, warehouse structures, laydown areas.

- and parking lots. The estimated acreage for the various areas is as follows:

1. Parking Lots and Roads 87 2.- Power Elo k Area 14

~ Map's showing transmission corridors associated with the Zimmer Station were previously submitted to NRC as Environmental

. Report-Operating. License Stage (ER-OL) Figures 3.9.1 and 3.9.2.

These . figures have been reproduced and are provided as Appendix I

- to this report. Construction of these lines has been completed.

The,Zimmer-Silver Grove and Silver Grove - Terminal transmission lines were addressed.in ER-OL, Section 9.1.

Question 2:

Identify on the site plan all structures. Indicate which

- structures will be removed and which will remain. Provide a

schedule for removal of structures and describe the method of debris disposal.'

{

' Response All' construction related facilities are' identified on Figures 1 and

' 2. Figure'3 identifies those construction facilities which are considered permanent and will remain. In addition, the

,-meteorological towers!.will continue to be. utilized to collect and-supply information for. site environmental. studies. The transmission lines (Figure'.1) are in; service an will continue to

. provide-interconnections to various.CG&E sub-stations and neighboring utilities.

The temporary construction facilities, consisting for the most

, . part of- mobile office trailers, are identified by trailer number

< on Figure 2.  :

All such-temp'rary o office trailers have been removed

from site. lit is anticipated that between 4-6 tool trailers'will be kept for storage of construction tools, supplies and equipment.

Debris resulting from removal of the permanent building

discussed above, will be removed from the site utilizing the --

services of a waste contractor. Disposal will be at the waste

Dames & Moore was contracted to prepare a report describing the

-status of the site and recommending a program which would leave the:

f Zimmer site in a stable and environmentally sound condition until i  ?

work on-the coal. plant conversion begins. The Dames & Moore J<

' report, Environmental Review of Zimmer Site Scatag, is attached and

, i e #54 contains information in response to this questjon.

Construction of transmission lines associated with the station has been completed and the lines are in service as part of the Company's transmission system. Disturbed acreage has been restored, and maintenance of transmission line rights-of-way will continue'in accordance with Company procedures and applicable regulations.

t Questig,4:

Describe plans for future use of the site to the extent that such plans have influenced the selection of site restoration activity, if any. Indicate the anticipated schedule for future use and describe how the future use influences the proposal for restoration work.

Response

As a result of the decision of the Applicants to cease construction of Zimmer as n nuclear plant and utilize their best efforts to convert the Zimmer Station to a coal-fired facility, the Zimmer site will not be abandoned and vi i continue to use many of the Zimmer/ site facilities in the conversion design. As a result, prudent management dictates that a decision on the usefulnese of these site improvements be made in conjunction with design efforts for the conversion prpject.

A commitment, at this time, as to witich of the site facilities t

would be used would impose unnecessary and undesirable restraints on the layout and final design of the conversion project.

Preliminary design and construction plans indicate that the n >

existing permanent construction officcs, shops, warehousing A- facipitiesandlaydownareasarewellsuitedandlocatedtosupport

Final site and station layout may require modifications to current grading and elevation profiles and possible extension and/or relocation'of onsite roadways and railroad spurs. Therefore, any site modifications and redress measures should occur in parallel with $he final ' design .and construction of the *.or: version project.

For example, preliminary conversion site layout utilizes the construction parking lot and Building I areas for the boiler room, flue gas precipitators and main stack. Final configuration will be dictated by the design finally selected. The Applicant proposes no further site redress measures at this time, other than those identified in response to Question 5. As design and construction efforts proceed, disturbed site areas and any unnecessary site J. ' improvements implemented during construction of the Zimmer Station will be' modified consistent with site development and environmental requirements of a fossil fuel-fired electric generating station.

Question 5:

Describe. proposed restoration activities, if any, including procedures and schedules for grading, seeding, and planting which will.be done to leave the site in a stable condition.

Response

The recommended restoration program described in the attached Dames

& Moore report will be implemented prior to the end of December, 1984.

l QuestionJ:

l Indicate what permits and approvals will be needed from other l federal, state, or local agencies for any of the site restoration I

work.

Response

We do not believe that any additional approvals or permits are i

needed from other federal, state or local agencies for the j implementation of the restoration program. Should the need for such permits or approvals become evident, the NRC will be notified l before work proceeds.
