VIOLATIONS

A., Condition Re orted Section F(5)of the Construction

Permit states, in part, that the applicant shall take the necessary mitigating

action, including those summarized

in Section 4.6 of the Revised Environmental

Statement, during construction

of the station, to avoid unnecessary

adverse environmental

impacts from construction

activities.

Contrary to the above, inspection

disclosed that, at least during the two week period prior to and including inspection, no mitigating

action was implemented

to control or otherwise minimize the unacceptable

impact of road dust resulting from construction

activities

at the station power block.Corrective

Ste s Taken and Results Achieved 1.Contractor

was remobilized

November 15, 1978, to assist in watering roads.2.Reimplemented

dust control measles November 15, 1978.Site roadways are watered as required to keep dust down.Watering is commenced when deemed necessary by either the Site Manager, Environmental

Engineer, Construction

Manager or General Superintendent.

I>, Corrective

Ste s Taken to Avoid Further Noncom liance 1.Additional

water truck has been ordered to improve the site's ability to control dust during dry periods.Date When Full Com liance Was Achieved November 15, 1978 B.Condition Re orted Section 4.6 (4.6.l.l.e)

of the Revised Final Environmental

Statement, as referenced

in Section F(5)of the Construction

Permit, requires, in part, that erosion and soil runoff causing contamination

of surface waters will be minimized.

It further requires, during early construction

of the main dam, the use of smaller sediment traps, collection

ditches, and intercepts

to reduce the silt load to such waters.Contrary to the above, inspection

disclosed that the licensee failed to minimize contamination

and silt loading of Buckhorn Creek at the main dam construction

site.Corrective

Ste s Taken and Results AchievedPursuant to North Carolina Administrative

Code 15 NCAC 4B.0005a, an Erosion and Sedimentation

Control Plan was submitted to the North Carolina Division of Land Resources on April 7, 1978 for the main dam.The Plan was approved by the Division of Land Resources subject to the condition that modifications

could be required to improve the performance

and effectiveness

of the approved erosion control measures under actual field conditions.

Accordingly, the following additional

measures have-been implemented:

1.Placed stone filter around standpipe of silt pond loc<<ed south<<the cofferdam.

2.Constructed

additional, larger capacity, silt pond downstream

of original silt pond south of the cofferdam.

additional

silt pond northwest of the dam to catch runoff from adjacent spoil area.5.Enlarged and installed riser pipe in silt pond north of the dam on the east side of Buckhorn Creek.6.Seeded east bank of Buckhorn Creek at south end of dam.7.Put in additional

ditching along east side of Buckhorn Creek to channel runoff into the silt pond.8.Put in ditching along west side'of Buckhorn Creek north of the dam to direct runoff into the silt pond.Corrective

Ste s Taken to Avoid Further Noncom liance V II The senior CP&L representative

at the Main Dam shall accompany the contractor's

representative

on comprehensive

inspection

tours of all sediment control device>>at least monthly to ensure proper maintenance

and construction

of additional

devices as necessary, Date When Full Com liance Was Achieved December 21, 1978 C.Conditions

Re orted Criterion V of Appendix B to 10CFR50 as implemented

by Carolina Power and Light PSAR Section 1.8.5.5, states in part that,"Activities

affecting quality shall be prescribed

by documented

instructions, procedures, or drawings...and shall be accomplished

in accordance

with these instructions, procedures

or drawings." Shearon Harris Specification

CAR-SH-CH-6,"Concrete" and referenced

ASTM Standard C-136 require that sieves used for grain-size

analysis conform to the requirements

of ASTM Standard Ell.Contrary to the above, discussions

with responsible

engineers indicated that sieves used for grain-size

analysis of fine aggregates

are not checked for conformance

to ASTM Standard Ell.Corrective

Ste s Taken and Results Achieved 1.Procured Finescale Model No.20 Magnifying

Comparator

and set of reticles for sieve sizes in question.(Received on site December 21, 1978)2.Checked all sieves, sizes g4 through 4200, in use and in stock, for conformance

with ASTM Standard Ell nominal opening size requirements.

3.All sieves checked were found to comply with ASTM Ell requirements

with respect to nominal opening sizes.

Ste s Taken to Avoid Further Noncom liance l.A written instruction

has been drafted which requires marking and checking all sieves for conformance

to ASTM Ell when received and visually checking fine aggregate sieves for holes and tears prior to each use.Date When Full Com liance Will Be Achieved January 5, 1979
