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

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 problem that the modification is intended to correct occurred entirely on-site in the Lamediate 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 1 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 Cooline Pond Dike The vegetative integrity of the cooling pond dike was inspected in accordance with LaSalle county Station procedure LTS-1000-5 on 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 concerns:

1) One area at station marker 301 was noted in the March inspection as not doing well and reseeding in May was recommended. 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 j 1986.

3) The crown vetch along the east side of the outer dike was noted as being dried out and not doing well during the July inspection. After some rain, this area recovered and was no longer of concern.

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

• t 4.2.2. Monitoring of Foq and Ice Due to the coolina Pond i

The following is a summary 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 Environmental Protection Plan Appendix B Section 4.2.2 which is part of the operating license for LaSalle County Station Units 1 and 2.

4 Included are: Attachment 1, which includes all reported incidences of fog which restricted visibility to 1/4 miles or less and rime ice observations

in 1985; Attachment 2, which consists of copies of the four quarterly summaries of fog and rime ice observations for 1985; Attachment 3, which j includes the annual summaries of observations for the years 1980 through

1984; Attachment 4, which is the correlation of time ice observations on vegetation for the winter of 1984-1985; and Attachment 5, the report of the

" Inspection for Environmental Impact of Rime Icing", which was conducted by i a consulting plant pathologist 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 observation days during 1985, where visibility was restricted to less than 1/4 mile. There was one observation of time ice build-up occurring off the station propet.y. 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 i that there was one observation of reduced visibility that may have been i

enhanced by the pond. It occucted 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 l the condensing cooling water discharge, reducing 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 consistently reported in the monitoring program.

There was one off-site observation of rime ice in 1985; it was 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 ice observations were in the same localized area

near the circulating water discharge. Rime ice was observed on vegetation and on vertical surfaces. Rime ice formed on 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 and, therefore,

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

" Inspection for Environmental Impact of Rime Icing" will be made during the 1986 spring growing season of the areas which were subject to the time 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 1982, 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 Mile Year Than 1/4 Mile Downwind only 1985 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 cooling pond. It was light (1/16 inch) and did not persist. There was a period of continuous on-site rime 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 l influenced by the cooling pond.  ;

I There were four incidences of time ice reported in 1983, and more were j 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.

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

l

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 time ice formation. Section 6.2.1 of the LSCNPP 1 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.

7egetation in the vicinity of the LaSalle County Generating Statica was surveyed for damage caused by time toe deposition during the winter of 1984-83 This survey was done in acoordance with section 4-2-2(d) of the IaSalle County Station Dtvironmental Protection Plan on the ljth of May, 1985 with the assistance of j

Mr. B.B. Barriekman of the Commonwealth Edison Company and is the i second survey of this site done by Barry J. Jacobsen, Ph.D. 1 Summaries of the 4th quarter of 1984 and let quarter of 1985 L l of the Fog and Rise Ice Monitoring Program for the IaSalle Station I 1

were utilised to identify areas of most likely damage. The  !

survey area is shown in Figure 1 (attached). Also shown in this l figure are specifie sites sentioned in this report. The survey ,

area was sufficiently large so that similar plants sould be observed  ;

in areas reported to be with and without rise lee.  ;

1 Site #1 located around the cooling water diseharge was the site where rise toe was reported most frequently during January of 1945 Cottonwood, willow, autumn olive and sweet elover ,

j observed at this site did not show evidense of lee damage.

i Iowever, willows located north of the ecoling water discharge did ,

show more winter injury and sanker disease (Venturia and Cytospera)

! than other willows in the survey area. Winter injury was diag ' -

nosed based on tip diebeek and one sided oambium noorosis and bud l death. This winter injury is thought to be due to the ware i discharge water delaying the vernalisation process. This delay

• in vernalization does not allow the plant tissues to harden off i enough to prevent freesing injury when extreme cold oseurs. The I

{ winter injury noted was relatively staor in nature. Willows '

i growing 25-30 yards north of the cooling water diseharge also had l wood borer damage.

1 Autumn olive plantings in this area aise displayed.some dieback.

However, the distribution and type of dieback is suggestive of' prob-l less relating to transplanting and plant establishment.

Sweet elever growing in this area showed no evidense of i

seethering such as would be expeeted from toe damage.

! Site #2 loested to the west of the cooling water diseharge had

! apple sad ask. trees.uhist showed winter damage. This damage.is

thought to re%ste.te the verr.alisation probles mentioned above and not les daange..-

Dogweed standings at this site showed evidence of transplant j

I damage agnia in '1943, although most plants show evidense of recovery.

l Sweet elever and erown vecoh growing at this site showed no i signs of ice smothering.

i 1L13.43 was characteristie of erewn veteh growing on the banks

of the pond containment dike. Growth was excellent and there was little sign of the Volute 11a canker disease seen in the 1984 survey.

I Site #4 was contiguous with observation site #7 used in the

fog and rise ice monitoring reports. Diebeek was noted only in

{ a row of old Osage orange trees growing adjasest to a pasture.

, . Attachment 5 Page 3 of 4 1985 Folear Survey Page 2 Diebeek was not characteristia of ice or winter damage. Cieback

was sharacteristie of root damage and/or canker or decay problems.

Sita M was loested between tog and rise ice observation sites M and M. A new acme with new landscape tree plantings was located at this site. These plantings osourred in 1984 and did not show ice or winter damage.

Site M was located at 0.7 miles west of fog and rise loe observation site M. An old PAanting of hard amples showed 4 evidense of diebeek relating to desay at this abandoned building site. There was no evidence of ice damage.

Conclusion Rise teing was not a factor in vegatation injury is and around the Isaalle county Generating Station during the winter of 1984-85 J Diehaak associated with delayed vernalisation near the ecoling water diseharge site een be assoeisted with plant operation. However, this damage is einer and is limited only ts6 wbl1ews which often show e ,

vinter injury.  ;
