I 3.1 Plant Design and operation No changes in station design of operation, tests and experiments were made in accordance with subsection 3.1 which involve a potentially significant unreviewed environmental issue.

l A modification to the Condenser cooling water discharge canal to correct an on-site fog and ice problem was evaluated for potential environmental impacts in accordance with subsection 3.1. This evaluation delineated that no significant environmental impact would occur based on the following conclusions:

1. The fog and ice prob 1Gm that the modification is intended to

( correct occurred entirely on-site in the immediate vicinity '

of the condenser cooling water discharge.

2. The modification will not enhance any off-site fogging and icing (this based on past winters experience of the fog and ice forming on the easterly side of the discharge area).

3. There will be no discernable impact on the water quality of l

the cooling pond due to temperature increase.

4. The construction of the modification will not result in an increase in suspended solids in the cooling pond.

5. The modification and excavation spoiling areas are within the area previously disturbed by site preparation.

4.2.1 Vegetative Integrity on Conting Pond Dike The vegetative integrity of the cooling pond dike was inspected in accordance with LaSalle County Station procedure LTS-1000-5 og the following dates: March 9, 1985; April 30, 1985; May 31, 1985; June 29, 1985; July 31, 1985; August 30, 1985; September 30, 1985; and October 17, 1985. The above inspections resulted in the following concere.s:

1) One area at station marker 3D1 was noted in the March inspection as not doing well and reseeding in May was recomumended. However, during the April inspection, this area had recovered and was no longer of concern.

2) In July, work was contracted out to apply the herbicide Round up to the outer dike face in order to control the Canadian Thistle growth. This killed a majority of the Canadian Thistle and plans are to reapply the herbicide in 1986.

3) The crown vetch along the east side of the outer dike w&s hoted AS b2109 dried oyt and not doing Well during the July inspection. After soce rain, this area recovered and was no longer of concern.

No other items of concern were noted during the 1985 cooling pond dike inspections.

I 4.2.2. Monitoring of Poq and Ice Due to the Cooling Pond The following is a swamary of the data for 1985 of the operational fog and rime ice observations in the vicinity of the cooling pond including an analysis of the data and comparison to the 1984, 1983 and 1982 operating experience, and 1981 and 1980 baseline. This is in accOrdance with the Envir6nmental Protection Plan, Arpt,131x B. Section 4.2.2 which is part of the operating license for LaSalle county Station Units 1 and 2.

Included are: Attachment 1, whir' lncludes all reported incidences of fog which restricted visibility to 1 miles or less and rime ice observations in 1985; Attachment 2, which c6cRsts of copies of the four quarterly summaries of fog and rime ice osservations for 1935; Attachment 3, which includes the annual summaries et observations for the years 1980 through 1984; Attachment 4, which is the correlation of rime ice observations on vegetation for the winter of 1984-1985; and Attachment 5 the report of the

" Inspection for Environs!ntal Impact of Rime Icing", which wa3 conducted by a consulting plant pathclogist in May, 1985, to assess the effects of the time ice that formed on vegetation during the winter of 1984-1985.

In summary, there were six days out of the 238 observatien days during 1985, where visibility was restricted to less than 1/4 mile. There was one~

observation of rimo ice build-up occurring off the station property. There was a period of continuous observation of on-site rime ice reported during a period of extremely cold weather in January.

Analysis of the six off-site 1985 occurrences of reduced visibility shows that there was one observation of reduced visibility that may have been enhaheed by the nond. It occurred on the morning of February 8th and was limited to two downwind observation points.

On-site, during the cold weather, dense steam fog occurred in the area of the condensing cooling water discharge, r6dJcing the visibility along the driveway to the main gate and over part of the parking lot. This is a localized effect, entirely on-site, not involving any of the observation points on the public roads around the perimeter of the site, and has not been consist 9ntly reported in the monitoring program.

There was one off-site observation of rime ice in 1985; it wa's reported on the morning of February 8th, at two downwind observation points. The ice build-up was light, reported as 1/16 inch, and was not reported during the afternoon inspection.

All of the on-site rime L(e observations were in the same localized area nbar the circulating water discharge. Rime ice was observed on vegetation and on vertical surfaces. Rime ice formed as the vegetation, guard rails, fences and automobiles in the parking lot and during the extremely cold weather the ice persisted. As with the steam fog in the same area, this effect has occurred entirely on-site., not involving any of the observation points on the public roads around the perimeter of the site ande therefore,

has not been reported on a regular bacis in the monitoring program. An

" Inspection for Environmental Impact of Rime Icing" will be 3ade during the 1986 spring growing season of the areas which were subject to the rime ice occurrences during the 1985-1986 winter season.

Analysis shows that the 1985 data had one less observation of fog causing reduced visibilities than in 1984 and one more than in 1983, but fewer than in the years 1382, 1981, and 1980. As shown below. there were six observations in 1985, seven in 1984, five in 1983, twelve in 1982, eleven in 1981, and ten in 1980.

Total observations, visibility Less Visibility Less Than 1/4 Mlle Year Than 1/4 Mile Downuind OnlY 19S5 6 1 1984 ~7 0 1983 5 1 1982 12 0 1981 11 1 1980 10 0 It is apparent that there was little or no enhancement of off-site fog conditions that could be attributed to the heat rejected to the cooling pond.

There have been only three times in the six years of observations that a visibility reduction under a 1/4 mile occurred downwind of the pond without any similar upwind or cross wind fog observations.

In 1985, there was one off-site observation of time ice, downwind of the coolirsg pond. It was light (1/16 inch) and did not persist. There was a period of continuous on-site time ice build-up in the area of the cooling water discharge, where the entrance road crosses the discharge. All the rime ice observations in 1984, 1983 and 1982 were also localized to the same area where the entrance road crosses the cooling water discharge canal. In the pre-operational period there were two observations which occurred during a period of extremely cold weather in January, 1982, which was before fuel loading. There was one observation in 1981 in late December under conditions which combined very cold air temperatures and an area wide light fog which resulted in a natural rime ice formation off site but was apparently not influenced by the cooling pond.

There were four incidences of rime ice reported in 1983, and more were expected in 1984 with both units operating. This has proved to be true in 1984 and 1985 and during the prolonged periods of cold weather, the ice has persisted and built up.

Rn inspection for " Environmental Impact of Rime Icing" was conducted by a consulting plant pathologist Dr. Barry J. Jacobsen on May 15, 1985. The vegetation in the affected area was inspected and found not to have suffered

any observable effects from the rime icing that occurred during the winter of 1984-1985. Attachment 5 is a copy of the report of the inspection.

As a result of the occurrences of steam fog and rime ice along the on-site access road, corrective action has been taken. The channel carrying the condenser cooling water discharge was rerouted and it is planned to cover it for part of the way to increase the distance between the point where the steam fog is formed and the access road. The rerouting of the channel is across an on-site area which was previously disturbed by construction. This action was evaluated and recorded as specified in Section 3.1 of the EPP.

The experience through 1984 of pre-operational, one unit operation and, in 1984 and 1985, of two unit operation, has demonstrated that operation of the station and the cooling pond has not been a major contributor to the frequency, extent or density of fog in the observation areas along the public roads surrounding the station nor has operation caused any persistant off-site incidences of rime ice formation. Section 6.2.1 of the LSCNPP Final Environmental Statement requires the monitoring program to continue through at least one 12 month period of reasonably complete two unit operation. This requirement has been fulfilled and the applicant has requested termination of the off-site fog and rime ice monitoring program.
