IV. AQUATIC ECOLOGY MONITORING PROGRAM The aquatic monitoring program will be an integrated program for all phases of WNP-3 site development and use. The intensity of effort on the monitoring program wil1 vary with increasing activity immedi-ately before and after the initial operation of WNP-3. Continuous
, evaluation of monitoring data will be accomplished to produce a more efficient environmental surveillance program. Portions of the pro-gram may be adjusted depending upon an evaluation of program results.
A. Construction Aquatic Ecology Monitoring Program Construction monitoring of periphyton, benthic macroinvertebrates, water quality, river fish and stream fish was performed for WNP-3 from 1976-1982. Based on the state of construction and a review of the data, construction monitoring is considered complete.
B. Preoperational Aquatic Ecology Monitoring Program Based upon analysis of the construction phase data, the following preoperational monitoring program will be implemented:
- 1. Benthic Macroinvertebrates
- a. At least one year prior to fuel load, collect benthos every two months, March through November (conditions permitting). The samples will be collected from five Chehalis River sample locations: upstream of the dis-AN ,4 charge (both in and out of the area subject to possible
.}~h current reversals), discharge area, edge of the mixing p\s.lct - zone (100' downstream from the discharge), and down-stream of the discharge beyond any appreciable influ-ence. As close as practical, the sample locations will be in line with the center of the discharge. The samples will provide data on benthos density, species composition and biomass.
- 2. F_i s h
- a. Adult Salmon Movements Prior to fuel load, evaluate the technical aspects of collecting and tracking the movements of migrating adult coho salmon in the vicinity of the WNP-3 discharge on the Chehalis River.
- b. Site Stream Spawner Surveys
~
Spawner surveys will be performed on selected site streams to assess the success of stocking efforts. Spawner surveys will include counts of a'dults and visible redds in known spawning areas. Surveys will be performed every two weeks during November-December on Workman, Fuller and Elizabeth Creeks for salmon. Surveys will be performed on Workman and Fuller Creeks once at the end of February and April, 1984, for trout. The Washington Department of Game will notify the Supply System if they want sur-veys performed in 1985. The spawner surveys began in November 1982 and will continue at least for salmon, through December 1985.

, c. Site Stream Electroshocki_ng The only site streams with any potential of being impacted by WNP-3 operation are Elizabeth and Fuller. Elizabeth Creek has the potential for dewatering as a result of
- Ranney well operation. Perform stream electrofishing at locations E-1 and F-1, respectively, on Elizabeth and Fuller Creeks. Initiate the program one year prior to fuel load and sample annually in August, Density, popu-
\ lation estimates and length determinations will be made
% only for salmonids. In addition, monthly June-October, '
walk Elizabeth Creek between station C52 and the mouth (c5f) ,
s w to locate any possible dewatered areas which would impact
\ fish. Collect stream discharge data at both locations (con-ditions permitting).
C. Operational Aquatic Ecology Monitoring program The operational aquatic monitoring program will be a continuation of the construction and preoperational monitoring program. The scope l of the operational aquatic monitoring program will be determined as the results of the construction and preoperational programs are eval-uated. This program will be developed by the Supply System and approved by the Council prior to operation of WNP-3.
V. WATER QUALITY MONITORING PROGRAM The purpose of this program is to monitor water quolity parameters. Data i obtained by this program will also supply necessary information to the study of the aquatic life in the river.
A. Construction Water Quality Monitoring Program Water quality was monitored for WNP-3 from 1977-1982. Based on the state of construction and a review of the-data, construction moni-toring is considered complete.
B. Preoperational Water Quality Monitoring Program Table 2 presents. the water quality parameters, sample locations and sampling frequencies for the preoperational water quality monitoring program. Sampling will be initiated at least one year prior to fuel i load.
C. Operational Water Quality Monitoring' Program The operational water quality monitoring program will be a continu-ation of the preoperational monitoring program. The scope of the ,
operational aquatic monitoring program will be determined as the results of the construction and preoperational programs are evalu-ated. This program will be developed by the Supply System and and approved by the Council prior to operation of WNP-3.
D. Thermal Effluent Monitoring Chehalis River temperatures will be monitored in conformance with the requirements of the discharge permit.

VI. TERRESTRIAL ECOLCGY PROGRAM e
The terrestrial ecology monitoring program for WNP-3 is part of an inte-grated monitoring program for construction, preoperational and operational phases.
A. Construction Terrestrial Ecology Monitoring Program The terrestrial ecology of the WNP-3 site was monitored from 1977-1982, Specific programs were biogeochemistry, litterfall and litter decomposition, banana slugs, deer, small mammals and birds.
Results are presented in annual and summary technical reports.
B. Preoperational Terrestrial Ecology ftonitoring Program Based upon analysis of the construction phase data, the following preoperational terrestrial monitoring program will be implemented to assess the , impact of cooling tower operation on plant communities:
- 1. Aerial Photography Perform remote sensing imagery twice annually (i.e., spring, late summer) in selected areas around the WNP-3 site. The pro-gram will establish a baseline of vegetational spectral signa-tures attributable to natural and man-made stresses. Aerial A photography-of the vegetation communities in the vicinity of f WNP-3 will be used to detect and assess the significance of t damage, or lack thereof, as related to cooling tower drift.
<. The program will be conducted twice prior to fuel load.
- 2. Chemical Composition of Soil and Vegetation x, -
Chemical and physical properties of soil and vegetation samples will be analyzed to provide a baseline for comparison with oper-ational analyses. Soil and vegetation samples will be collected from projected high drift deposition areas and control areas annually. The soil samples will be analyzed for pH, conductivity,
, bicarbonate, carbonate, sulfate, chloride, fluoride, copper, zinc, sodium, lead, magnesium, potassium, mercury, cadmium, chromium and calcium. The vegetation samples will be analyzed for sulfate, chloride, sodium, potassium, calcium and copper. The program will be initiated two years prior to fuel load.
- 3. Vegetation Studies Vegetation study plots will be monitored in the spring in pro-jected high drift deposition areas and control areas. Species composition, density and/or canopy cover will be determined for species in each plot annually. The program will be initiated two years prior to fuel load.
C. Operational Terrestrial Ecology Monitoring Program The operational terrestrial ecology monitoring program will be a continuation of the preoperational monitoring program. The scope of the operational program will be based upon the results of the construction and preoperational programs. The operational program will be developed by the Supply System and approved by the Council prior to the operation of WNP-3.
