terrain, therefore, is not expected to experience the large number of heavy fog days observed at the regional airports.

FSAR states that the tornado strike probability is approximately 1.4 x 10 7 years 1, the plant has been designed to exceed the RG 1.76 Region I:I criteria for wind speed, pressure drop, and rate o.f pressure drop (107 m/sec (240 mph), 0.11 kg/cma (1.5 psi), and 0.04 kg/cm/sec (0.6 psf /sec), respectively).
Another meteorological phenomenon of note in the area is the general cloudi- }
e ness that results in less than 60 clear days per year. Similarly, in the region there is heavy fog with visibility of 402 m (0.25 mile) or less 60 to 80 days annually. y' -/N#ERT 8 /
Prevailing winds in the area, as measured at Olympia, are from the southwest quadrant and average about 3.1 m/sec (7 mph). Onsite 10-meter wind observa-tions shown in Figure 4.8 present the annual wind frequency distribution r measured during the period October 1979 through September 1981. The maximum fastest mile wind speed observed at Olympia, was 26.8 m/sec (60 mph).
4.3.4 Terrestrial and Aquatic Resources .
4.3.4.1 Terrestrial Resources The terrestrial ecology of the WNP-3 site and surrounding area is described in Additional data collected from 1975 through 1980 Section 2.7 of the FES-CP.
are given in ER-OL Section 2.2.1. From 1978 through 1980, the terrestrial ecology program was concentrated within four small watersheds (ER-OL, Figur2.2.2-2). !
These watersheds were selected to be representative of the two major habitat types surrounding the site, maturing second grdwth coniferous forest and recent WNP-3 DES 4-19

Analysis of data collected during these studies showed that the procedures employed for erosion control and for preventing silt from reaching surface waters were effective. The major effects of construction have passed. During 1981, suspended solids concentrations in the onsite streams were higher during periods of high rainfall but were not uniformly greater than values measured in streams away from the influence of construction activities. Hyatt Creek showed values for suspended solids and turbidity that were higher than those at the control station on the Chehalis River. In Hyatt Creek, the average turbidity was 42.0 compared to an average of 6.4 in the Chehalis upstream.
Values in Hyatt Creek ranged up to 500, and a maximum of 34 was observed in ,
the Chehalis. Other streams receiving site drainage were comparable in turbidity to the control (Envirosphere, 1981).
Data collected on the Chehalis and Satsop Rivers subsequent to the issuance of the FES-CP improved the description of river water quality but did not alter conceptual understanding of the processes affecting water quality. Of major concern to the State of Washington during its licensing proceeding was the effect of toxic metals on the highly valued salmonids of the region. Particular concern related to copper. WWP-3 would influence copper concentration through the release of corrosion products and through the concentrating effect of evaporative cooling.
The original waste discharge permit for the project all but forbade the dis-charge of water from the project by limiting the concentration of copper in the discharge to a value near the ambient concentration. In 1979, a revised .
! discharge permit gave some relief but required the utility to conduct studies of the backgro'und copper and of other heavy metal concentrations in the Chehalis River for a 52-week period (Washington, 1979). This study was conducted during the period November 1980 through October 1981 (Envirosphere,1982a). Table 4.2 shows the average value and the range of values observed for total ion concen-tration for each metal during this study. Also measured but not included in the table was the dissolved fraction of the metals.
4.3.3 Meteorology WNP-3 is situated in western Washington State where the climate is comprised of warm, dry summers and wet, mild winters. These conditions are the result of proximity to the Pacific Ocean and the presence of semipermanent high and low pressure centers off the coast, which migrate in a north-south manner (Water Info Ctt, 1974). Temperatures#
normally vary from an average January minimur of approdimately -1*C (30 F) to an average July maximum in the middle 21*C (70"F) range (Baldwin, 1973). Temperature extremes observed at Olympia, WA, were -18*C (-8 F) and 40 C (104*F) during the 40 year period ending in 1981 (Nat'l Climatic Ctr, 1973, 1981). Precipitation usually occurs every month, although the greatest portion of the nearly 1295 mm (51 inches) of annual precipitation occurs from October through March.
The precipitation total includes the water equivalent of the snowfall that occurs from November through April. Thunderstorms are recorded infrequently and occur primarily in spring and summer. There is a corresponding very low frequency of tornado events, with only one tornado occurring in the one-degree square that includes the site during the period 1916 to 1979.
