EHEB Rdg File MEMORANDUM FOR: Robert B. Samworth, Section Leader , RBallard/ File .

Environmental Engineering Section, EHEB EPentecost FROM: EdWin D. Pentecost, Environmental Scientist Environmental Engineering Section, EHEB

SUBJECT:

STATUS OF WNPPS-3 SITE On April 11, 1985, Clarence Hickey and I called Mr. Fred Hahn, Washington Department of Ecology, Olympia, Washington (206-459-6143) to obtain an independent viewpoint of the condition of the WNPPS-3 site. Mr. Hahn is also a member of the state's Siting Council. We wanted an update regarding some erosion problems observed during the NRC site visit in March 1983 and information on any stabilization or other mitigation measures implemented since 1983.

In general, Mr. Hahn was very satisfied with the stabilization and revege-tation efforts along Stein Creek immediately south of the site and the efforts along Elizabeth Cresk in the area of the Ranney Wells. He also indicated that no significant' environme.1tal impacts are likely to occur during the next 4-5 years as WPPS-3 construction is resumed and ceropleted (see Attachment A for specific remarks).

Clarence and I then held a conference call with Messrs. Arthur Moore ')

(206-482-4428) of the Washington Power Supply System and Al Christian, the environmental scientist at the WPPS-3 site. They essentially agreed with  :

Mr. Hahn on condition of the WPPS-3 site (see Attachment B for specific remarks). Mr. Moore agreed to forward a 1983 and recent site aerial photo-graph for my review.

Based on information obtained from these calls it seems unlikely that I would need to visit the WPPS-3 site to complete'the environmental review for the CP extension.

• Notes from Telephone Conversation with Mr. Fred Hahn, Washington Department of Ecology

• Mr. Hahn stated that the construction of WNPPS-3 was 75% completed. The remaining construction activities will occur mainly in the power block' area and are not envisioned to result in any environmental impacts to the site or immediate vicinity. Documentation of erosion control activities has been submitted to the state siting council. He will forward copies of the reports to us. He offered the following information pertaining to erosion and stabilization problems we observed during the site visit along Stein Creek and Elizabeth Creek:

Stein Creek All slopes along creek banks have been stabilized and revegetated with the standard seed mix. Slopes were stabilized using rock arranged in a series of terraces, and cloth mesh mat over bare soil. Douglas fir and red alder seedlings have become established naturally amidst the herbaceous ground cover. The pump and sections of the dam at the base of Stein Creek have been removed.

Elizabeth Creek The area between the river and the creek near the Ranney Wells has been reseeded and presently shows a high cover of grasses. Additional rip-rap was placed along the stream bank.

The Washington Department of Fisheries worked with the Supply System to implement a fish stocking program along Elizabeth, Workman and Fuller Creeks to ccmpensate for fish losses due to habitat loss during the con-struction related erosion events of the late 1970's. Cfoho salmon and steelhead trcut were stocked starting in 1980 and continuing through 1983.

Annual fall surveys have shown the stocking efforts to be a success. The final fall survey will be conducted in 1985. The Siting Council has annual survey reports prepared by the Washington Department of Fisheries on the fish stocking program.

The fish bioassay of trace elements and heavy metals has been completed.

Mr. Hahn believed the studies were of high caliber and the first of their kind using native species in this part of the northwestern U.S.

The offsite emergency operations facility is under construction. Excavation complete, foundation is complete, spoil piles have been seeded, no signifi-cant adverse impacts of construction envisioned.

Notes from Telephone Conversation with Mr. Art Moore, WPPS-3 and Mr. Christian of Ibasco (Consultant to WPPS)

In general, both Mr. Moore and Mr. Christian were satisfied with the erosion control efforts at the site. They offered the following comments in response to our questions pertaining to condition of the site:

Elizabeth Creek Ambients water quality conditions have been observed in the Ranney Well area for the last 11 years. The area between the river and creek was seeded with a mixture of fescue, rye grass and treefoil. ,

Stein Creek Creek bank slopes reseeded in late 1982. Presently have good cover of grasses and growth of volunteer tree species. Sand bag area along creek was removed in late 1982 and the pump station was removed.

Hyatt Creek The sedimentation ponds near the wet lab have been filled in from runoff due to Weyerhauser logging operation in the area. The area cleared was outside the western boundary of WPPS-3 site.

The forested area immediately east of the site boundary was logged and burned in 1983; the area was planted with Douglas Fir seedlings in late 1983; no erosion problems from the logging operation have occurred since planting of seedlings.

The BPA switchyard is now completed.

The 500 KV line is yet to be constructed.

Occasional observations of bald eagles on gravel bars along the

, Chehalis River near Ranney Wells.
