This D89 Environmental Operating Report for' the-North-Anna Power Station is -
submitted by Virginia Electric and Power Company ai required under Section 5.4.1'of Appendix B, Environmental. Protection' Plan (EPP).- The objectives of the EPP are to verify that the power station is operated in an environmentally acceptable manner; to coordinate NRC requirements and maintain consistency with other federal, state
-and local requirements; and to keep NRC informed of the environmental effects of facility construction and operation.
During 1989, no significant adverse environmental impact occurred as a result of;the operation of North Anna ~ Power' Station. Units 1 and 2.
Aquatic issues are-addressed in the licensee's NPDES pert t number VA 0052451 issued by the Virginia State Water Control Board and t h NRC relios on this agency for regulation,of matters involving water quality and s
aquatic biota. Listed below are the suimhries and reports as required under Section 5.4.1 of the EPP.
s Plant Design and Operation (Section 3.1[
1-There were no changes in station design or operation proposed in 1989 that involved a potentially significant unreviewed environmental usue.
fransmission Line Right of Way Herbicide Nuv.aement 1

t Transmission 1.ine Right of Way Erosion Control l'nspection Erosion inspections of rights of way were conducted for the North Anna-i.
Midlothian, North Anna-Louisa, and North Anna-Ladysmith 500 KV lines and on the North Anna-Gordonsville 230 KV line on July 20, 1989.
Locations were recorded of I
erodedareas.ontheNorthAnna-Gord'onsvill$,NorthAnna-Midlothian, North j
7 Ar.na-Louisa and the North Anna Ladysmith lines. Most of these eroded areas were caused by vehicle travel along the right of way.
All areas were disced.
fertilized, seeded, and mulched and additional straw bales were installed to
}
prevent erosion; i
Stat, ion Site Erosion Contral f
i An'on-site erosion control inspecti6n was performed at North Anna-Power Station-g by the Civil / Design Engineering Department beginning December 5,1989 and I
ending on December 14, 1989, acccrding to Periodic Test Procedure.1-PT-9.3, Erosion Control Ins p ction - Station Site.
During the inspection minor erosion wasinoted a
around the lip of the paved drainage ditches in several locat. ions.- Also, soil and grass were found to be present at the slope transitio%of the paved drainage ditch leading from the road to the disch'ar p canal near the lcwer end of the canal,
'tation side. Minor crosion also existed east of the intake structure along the portion of the shoreline not reinforced with riprap.
Corrective action is. not '
required for any of these areas at this tin:e but tte erosion should be monitored, i
y The paved drainage. ditch adjacent to the sewage plant has been undermined by severe erosion to thi extent that the center portion is cracked and caved in, g
l Significant erosion was also found at the Southwest corner of the sedimentation h
pond South of dike V, apparently -due to - broken discharge culvent.

Hydroelectric Power Project A study of fish passage from Lake Anna to the North. Anna River was conducted durir' '06,1987, u.1988 to assess the need for intake. screening at the North Anna liydroelectric Facility.
Results indicated fish passage rates were very low, suggesting that turbine - induced mortality was minimal and that screening was unnecessary..A detailed report of the fish passage study was forwarded to the reviewing agency, Un'+.ed States Fish and Wildiife Service.
