STN 50-521 STIPULATION In response to the Appeal Board Order in ALAB-5543 and in order to provide assurance that the pink muckett pearly mussel (Lampsilis orbiculata) will be protected during construction of the Hartsville Discharge Diffuser, it is hereby stipulated by and between Counsel for the NRC Staff, Counsel for the Applicant, and Counsel for the Intervenors, that the following underlined wording, if approved by the Appeal Board, will amend the Hartsville

. Monitoring Plans and Construction Permit:

p Diffuser Excavation Periods 1,.

Prior to initiation of the dredoing activity, the Permittee shall give three weeks written nc. ice of the planned construction schedule to the NRC Staff, the Intervenor, the U.S. Fish and Wildlife Service,

_m the U.S. :nvironmental Protection Agency and the State of Tennessee.

Sedimentation traps will continue to be placed at the same stations

~

used in the prediffuser excavation period. The traps will be returned twice per 8-hour dredging crew working shift (once after 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and once after 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />) during excavation of approximately the first 1,000cubicyardsofmaterial.l/ Additional sedimentation traos will be placed at the same stations to orovide a measure of the accrecate (total) deposition of silt which results from the construction activity during the e.vcavation period. Acolicant will determine the death of sediment deposited in the traos.

If one-cuarter inch or more _ aggregate sediment is found to have been deoosited in at least two samole traos, dredging will be stopped.

Oredging may be resumed if later observation

.of sediment traos shows that the aggregate sediment decosition has been reduced to less than one-cuarter inch.

Before using any artificial means to remove the sediment, Apolicant will obtain the concurrence of the Department of Interior, l/ 8 NRC 525, item 1.

. 3.

Turbidity levels of the river above and below the dredging activities will be measured at 1-meter depth intervals from surface to the bottom and averaged over the water column to document changes in natural turbidity levels resulting from these activities. ' Samples will be taken hourly during excavation.

Natural turbidity levels of record as defined in the Hartsville Nuclear Plant's ER will be the feedback criteria for regulating the rate of instream dredging. Maximum documented levels of turbidity are 85 ppm (JTU).d/

4_.

Measurement of light intensity in the water column will be performed with a submarine photometer both above and below the dredging activities.

Measuraments will be made hourly during excavation. A 50 percent reduction in the depth of 0.1 percent of the light transmission at sc.me selected point at the mussel bed relative to an upstream location (above the dreoging activities) will be the feedback criteria for ins $itating corrective mitigative actions. 2I 5,.

Should the agorecate silt deoositicn or turbidity levels t.

t penetration data indicate a need for mitigative action, spector will Yeport his findings and make his recommendation to the project environ-mental engineer, who will present these findings and recommendations to the project manager. The project manager will make the decision on the mitigative actions to be taken, i.e., to slow down or halt construction. 3/

Dissolved oxygen, pH conductivity,'and temperature profiles will be made at upstream and downstream locations to document any perturcations of these parameters.

7_. During blasting activities, mussels will be placed by scuba divers at established intervals from tha area of the blasting to determine if mussels on the Dixon Island bed are harmed by shock waves frca these activities.U o threatened or endangered species will be used.

N 8_. Within 30 days after completion of the dredging activity, the Permittee shall submit to the NRC Staff a summary report of the results of the monitoring clan with cooies to the Intervenors, the U.S.' Fish and Wildlife Service, the U.
