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 Achieved Pursuant 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.

3. Seeded slopes around the two south silt ponds.~

4. Constructed 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.

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.
