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 screage for each such disturbed area.

Response

A site plan as of January 21.1984 (announced decision to convert the Zimmer Station to coal) is shown on Figures I 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 Block Area 14 3.

Switchyard 2

4.

Cooling Tower 6

5.

Construction Support Facilities 48 (including laydown compounds) 6.

Settling Basin 63 7.

Meteorological Towers 9

Maps showing transmission corridors associated with the Zimmer Station were picviously 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 CC&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 temporary office trailers have been removed from site. It is anticipated that between 4-6 tool trailers will be kept for storage of construction tools, supplies and equipment.

These trailers will be located adjacent to the permanent i

construction shops. The Construction Office Building (Coordinates C-4) and temporary additions to the Carpenter Mill Shop *(D-6), Weld Test Shop (D-6), Ironworkers Shop (D/E-6) Electrical Shop (E-7),

Pipe Shop (E-6) and Paint Shop (F-7) were constructed during various time periods of the project and will be removed. All demolition will be accomplished by August 31, 1984.

Debris resulting from removal of the permanent building (Construction Office) and the temporary additions to the shops discussed above, will be removed from the site utilizing the services of a vaste contractor. Disposal will be at the waste contractor's approved landfill cperation. All debris resulting from building demolition will be removed by October, 1984.

Construction Buildings D, E, F (D-4), G, H. (D-5), I (C-2), J (D-3), K (E-2) and L (C-3) shown on Figure 2 were planned additions to the construction complex but were not erected.

Question 3:

i Describe the status of the site, with particular attention to disturbed areas and to related erosion and runoff control measures.

1

Response

Dames & Moore was contracted to prepare a report describing the 8

status of the site and recommending a program which would leave the i

Zimmer site in a stable and environmentally sound condition until work on the coal plant conversion begins. The Dames & Moore report, Environmental Reviiw of Zimmer Site Status, is attached and contains information in response to this question.

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.

Question 4:

i 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 I

work.

Response

As a result of the decision of the Applicants to cease construction i

of Zimmer as a 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 will continue to use many of the Zimmer site facilities in the conversion design. As a result, prudent management dictates that a decision on the usefulness of these site improvements be made in conjunction with design efforts for the conversion project.

A coenitment, at this time, as to which of the site facilities would be used would impose unnecessary and undesirable restraints on the layout and finsi design of the conversion project.

Preliminary design and construction plans indicate that the existing permanent construction offices, shops, warehousing facilities and laydown areas are well suited and located to support future construction.

k Final site and station layout may require modifications to current grading and elevation profiles and possible extension and/or 1

relocation of onsite roadways and railroad spurs. Therefore, any i

site modifications and redress measures should occur in parallel with the final design and construction of the conversion project.

For example, preliminary conversion site layout utilizes the i

j construction parking lot and Building I areas for the boiler room, flue gas precipitators and main stack. Final cor?iguration will be dictated by the design finally selected.

The Applicant proposes no further site redress measures at this tius, other than those i

f identified in response to Question 5.

As design and construction 4

efforts proceed, disturbed site areas and any unnecessary site improvements implemented during construction of the Zimmer Station 4

will be modified consistent with site development and environmental j

requirements of a fossil fuel-fired electric generating station.

3 Question 5:

Describe proposed testoration activities, if any, including i

}

procedures and schedules for grading, seeding, and planting which 4

will be'done to leave the site in a stable condition.

Response

1 -

The recor. mended restoration program described in the attached Dames

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

Question 6:

Indicate what permits and approvals will be needed from other 4

federal, state, or local agencies for any of the site restoration work.

Response

We do not believe that any additional approvals or permits are needed from other federal, state or local agencies for the implementation of the restoration program.

Should the need for such permits or approvals become evident, the NRC will be notified before work proceeds.

Attention:

Mr. W. D. Waymire Manager of General Engineering Gentlemen:

Environmental Review of Zimmer Site Status For The Cincinnati Gas & Elect ric Company INTRODUCiION Dames & Hoore has performed an environmental review of the Zimmer site status at the W.H. Zimmer Station as requested by The Cincinnat a Gas &

Elect ric Company (CG&E).

This review focused on two part icular it ems:

1.

A description of the site's status, with particular attention to disturbed areas and to related erosion and runoff control measures 2.

Development of a restorat ion plan, including procedures and schedules for gradir.g and seeding, that will stabilize the site until construct ion of the coal plant begins The study entailed a reconnnissance of t he Zimmer site, discussions with CG&E personnel concerning the site status, a review of figures provided by CG&E showing the past and projected configurat ion of onsite facil: Lies, and the development of a restorat ion plan for disturbed areas.

SITE STATUS figures 1 and 2 show the configurat hon of onsite facilit les as of

{

3anuary 21, 1984.

These figures show the location of major onsite struc-tures, borrow areas, existing roadways, access routes, parking lots, fence lines, and the switchyard and transmission corridors. figure 3 presents the i

projected configuration of plant site facilities as of thn end of December l

1984.

A comparison of figure 3 with figures 1 and 2 shows that most of the const ruction trailers and miscellaneous buildings will have been removed by the end of December 1984.

The t railer and building-removal process is

(

already well underway.

The basic site profile and elevations have remained largely unchanged for approximately 7 years, except for the following major site modificalions:

4 I

i

Dames, & Moore The Cincinnati Gas & Electric Company May 31, 1984 Page

• A craf t-workers' parking lot covering approximately 10.6 acres was constructed immediately north of the main plant buildings during the f all of 1983; extensive fill and grading were required.

The panking surface and access ramp were blacktopped during December 1983 and January 1984 to minimize dust impacts on the est imat ed 3,000 craft-workers, plant personnel, travelers on U.S. Route 52, and nearby residents and communities.

• A parking lot addit ion (see coordinat es F-6 on figure 2) was con-st ruct ed during the same period as t he craf t-worker 's parking lot.

This parking lot was also blacktopped to minimize dust emissions.

• The existing parking areas aloer U.S. Route 52 (coordinaces A-3 through A-6 and 8-3 through B-6, t.,ure 2) ure also paved in late 1983/carly 1984 for the same environment 1 reasors indicated above.

The parking area bounded by coordinates A 5 L.irough A-8, and B-6 through B-8 was not paved because this area was designated as an overflow parking f acility and the anticipated use was minimal.

'In the case of the formerly proposed buildings C, H, and I (see figure 2), pilings were installed, out the buildings were never const ructed.

The top of the palings protrude approximately 2 feet off the existing ground surface.

There are no immediate plans to remove or grade over I

these pilest as present ly envisioned, these areas will be used as laydown areas.

Overall, with the exception of the areas listed above, site drainage l

has been well established over the last several years.

Sheel runoff is directed towards drainage ditches and conduits, and no evidence of severe onsite erosion was observed during a May 1984 reconnaissance of the Zimmer site.

In general, the recent site modificalions listed above conform to existing drainage patterns, and there is no reason to expect a significant increase in the rate of crosion due to these modifications, j

The tratters and temporary buildings that either have been or will be L

removed are typically underlain by crushed rock or slab foundations.

There are no plans to remove the slabs or take up the crushed rock at this t ime.

It is envisioned that areas covered by these materials could be used during I

construction of the coal plant facilities.

Unpaved areas interlying the trailers and buildings are covered by bare dirt, crushed rock, or a combination of the two.

Invader species of qrasses and weeds are scattered

{

throughout these areas.

RES10HATION PLAN Site restoration work should be designet to minimtre eros ten and windborne dust originating from disturbed areas onsite.

It should also be designed to preclude areas of standing water and saturated soils.

However, g

it should not necessarily be designed to landscape the site, which will

(

undergo additional disruption when coal plant const ruction activitles begin.

The recommended restorat ion program snould include three components:

grading, revegetalnon or the addit ion of crushed rock, and limited modifications to site drainage patterns.

Grading:

As indicated in Plates 1 and 2, limited grading is required and no significant cut and fill operations are envisioned. Grading should l

be designed to spread small mounds of dirt and rock found onstte; eliminate depressions where water is found to accumulate; smooth surfaces so re-i vegetated areas can be maintained; and, reduce slopes, especially adjacent to some of the drotnage courses, present ly subject to higher rates of i

erosion. During grading, supervision of earthmoving act ivit ies should be provided to ensure that grades are const ructed to direct runoff towards drainage ditches. Grading should be scheduled as soon as practical, prior

(

to any revegetation programs.

Revegetation/ Crushed Pock Additions: Plates 1 and 2 also show existing grassed-areas and areas where grass need should be applied. All bare soil areas should be reseeded; it should be at a field supervisor's discret ion to decide which areas of limited or sparse vegetative cover should receive seed to thicken ground cover.

Prior to seeding, the ground surface should be prepared by turning the soil with either a spring tooth harrow or a disc to a depth of approximately 4 inches; large rocks and debris should be removed.

Based on typical Clermont County soils, a seed mix consisting of the following grasses and legumes is recommended:

Percent Compositson Sericea lespedeza (hulled) 25 K-31 fescue 25 White clover 15 Kentucky /Marion bluegrass 25 Perennial ryegrass 10 Onsite soil chemistry tests should be performed prior to ordering the seed mix to adjust the mix for any unexpected condit ions.

The Cincinnatt Gas & Electric Company May 29, 1984 Page This seed mix is readily available, cost effective, quick germinaling, easily maint ained and ef fect ive for a fall plant ing.

The legumo component will help provide staying power over several seasons.

Broadcast seeding is recommended on flat to moderate slopes at a rat e of 65 lbs per acre, if the use of a hydroseeder in required for steep slopes, this rate should be at least doubled.

A common 10-20-20 blend fert ilizer is recommended for opplicat ion at n rate of approximately 350 lba por acre.

Also, appliention of pellet tred lime is recommended at a rat e of 80 lbs per acre.

After the oced mix, fertallrer and limo are applied, a chain should be dragged actoss the surface ta turn the seed under.

Straw mulch should then be blown onto the reseeded areas at a rate of 1 ton per acre. From a scheduling standpoint, the aceding effort should take place no Inter than the first week of October.

The addition of crushed rock should also be npplied at the discretion of a field supervisor.

In general, suf ficient rock should be applied to cover dirt nurfaces as required.

Although most of the areas requiring need and rock are located at the main plant site (see Plate 2), there are some arens that require seed and/or stone in the larger general site area (Plate 1), including:

1.

The perimeter of the nettling basin and certain adjacent nrens 2.

The two borrow areas immedintely north of the new craft-workern' parking tot 3.

Arena adjncent to the meteorological tower went of 11.5. Route 52 4.

Areas immediately ndjacent to the accena rond lending to the meteorological tower ennt of (J.S. Houte 52 5.

The borrow aren along 345 kV t rnnsm!solon corridor ennt of U.S.

Route $2 The two borrow arena (Items 2 nnd 5 nbove) will alon require nome drainngo modifications, as dancuated in the following nect ion.

Drainnan Hodt ricat ionn a Minor modi ficat ionn to the exist ing site drainage are ouggented to minimize erosion potent int and/or ellmannte nrens of standing water.

These arean include the two borrow nrenn previounty diocunced.

In general, thene modifical tono are relat ively minor.

Una nren requiring particular attention in a nmall impoundment immedini cly north of the new craft-worker parking lot.

This impoundment should be drnined and contoured to direct runoff towards Little Indian Creek, which would conform to natural drainage patterns hofore the new parking lot was constructrd.

Rip-rup should be Inid in the channel draining the pond nnd the aren should be revegetated according to the npecificalions prenont ou herein.
