SUPPORTING THE REQUEST FOR EXTENTIOW OF THE ,

DATES FOR COMPLETION OF CONSTRUCTION OF  !

COMANCHE F 7K STEAM ELECTRIC UNITS 1 ANu 2 CPPR-126 AND CPPR-127 DOCKET NOS. 50-445 and 50-556

1. Description of Proposed Action The' action requested is the issuance of an amendment to the captioned construction pemits for Comanche Peak Steam Electric Station (CPSES). The amendment would extend for 48 months the latest dates for completion of Units 1 and 2 respectively.

The construction pennit for Unit 1 (CPPR-126) would be extended fran a latest completion date of August 1,1981 to August 1,1985; she construction permit for Unit 2 (CPPR-127) would be extended from a latest completion date of August 1,1983 to August 1,1987.

2. Summary Description of the Probable Impacts of the Proposed Action _

The environmental impacts associated with construction of CPSES have been previously addressed in the NRC staff's final environmental statement, construction permit stage (FES-CP) issued J une, 1974.

The FES-CP identified the following four major impacts and effects due to construction:

a. Construction-related activities on the site will disturb . bout 400 acres of rangeland, not including the 3228 acres of land inundated by Squaw Creek Reservoir, which will be constructed in conjunction with the station. The land inundated includes 8106250 % ]

r r, w .

@ .s . .

< about 8 linear miles of Squaw Creek and'the adjacent-riparian

- cwmunities, _and 940 acres of crupland, which is considered

irreversibly lost. About 200 acres of this land not to be used for th'e' reservoir, plant' facilities, parking lots, roads,

switchyard, evaporation pond, etc., is to be restored by seed'ng and landscaping to prevent erosion.

b. Approximately 15 miles of transmission line corridors will require about 439 acres of land for the rights-of way.

I'

c. Ralocation of the current pipelines as proposed will involve m

about 100 acres. A railroad spur 10.2 miles long will affect 105 acres of land. Diversion and return lines between Lake Granbury ano Squaw. Creek Reservof r will affect about 100 acres.

d. Station constructson will involve some community impacts. As many as 8 fam residences will be displaced.- Faming, hunting, and grazing on the site will be suspended. Traffic on local reads will increase due to construction and commuting activities. Influx of construction workers' families (1150 peak work force) is ' expected to cause no major housing or

-? school problems. There will be a demand for increased services in Somervell and Hood counties.

[ The first three effects have already occurred. The reservoir was c

constructed and filling was completed in May of 1979. Landscaping has not been completed but there has been seeding to prevent erosion. Construction of the transmission lines has been completed; the railroad spur and diversion and return lines between Lake Granbury and Squaw Creek Reservoir have been completed.

The fourth construction impact, community impacts, has already peaked and is now declining. The construction work force peaked l

during the -second quarter of 1979.

Another impact, the subject of a construction permit condition, is g- groundwater withdrawal. At .the present time most construction

~

. water is- being supplied from treated lake water. As a result continued construciton will have little impact on groundwater.

As required by the construction permit environmental monitoring has been conducted. There have been no unreviewed adverse environmental impacts associated with construction and none are anticipated.

3. Conclusion and Basis for Finding of No Significant Impact On the basis of the above, it is concluded there will be on significant impacts attributable to this requested action other ti those already predicted and described in the FES-CP issued in June, 1974.
