i 4.2.1 veaetative Inteerity on Coolino 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: April 27,1984; May 31,1984; June 31,1984; July 29,1944; August 30, 1984; september 29, 1984; and October 28, 1984. The above inspections resulted in the following concerns:

1) The crown vetch, especially along the southern dike, does not grow weli during dry susmer months. The crown vetch is thick, along the dike and still provides adequate grour.d cover to prevent erosion.

At the end of dry periods, the crown vetch comes back very well.

2) A bare spot was noted by the Make-up discharge structure during the June inspection. This area re-seeded and the ground cover grew back.

3) canadian Thistle, a noxious weed, was found growing along tts cooling lake dikes. The Canadian thistle was picked and begged, prior to seeding, by station personnel and no longer poses a problem.

March 11, 1985 4.2.2. Monitorine of Foo and Ice Due to the Coolino Pond The following is a sussnary of the data for 1984 of the opera-tional fog and rise ice observations in the vicinity of the cooling pond including an analysis of the data and compariscn to the 1983 and 1982 operating experience, and 1981 and 1980 baseline. This is in accordance with the Environmental protection Plan, Appendix 3, section 4.2.2 which is part of the operating license for LaSalle county station Unit 1 and 2.

Included are: Attachment 1, which includes all reported inci-donces of fog which restricted visibility to 1/4 miles or less and rise ice observed on station property in 1984; Attachment 2, which consists of copies of the four quarterly summaries of fog and rime ice observations for 1984; Attachment 3, which includes the annual sunseries of observations for the yee.rs 1980 through 1983; Attachment 4, which is the correlation of Rime Ice observations on vegetation for the winter of 1983-4; and Attachment 5, the report of the " Inspection for Environmental Impact of Rime Icing, which was conducted by a consulting plant pathologist in May, 1984 to assess the effects of the time ice that formed on vegetation during the winter of 1983-1984.

In summary, there were seven days out of the 249 observation days during 1984 where visibility was restricted to less than 1/4 mile. There were no observativas of ice build-up occurring off the station property.

There were, however, ten cases of on-site rime ice reported during the year.

Analysis of the seven off-site 1984 occurrences of reduced visi-bility shows that there were no observations of reduced visibility that may have been enhanced by the pond.

On site, during the cold weather, dense steam fog occurred in the

area of the condensing cooling water discharge, reducing the visibility

along the drivewey to the main gate and over part of the parking lot. Ihis is a localized effect, entirely on-site, not involving any of the observa-tion points on the public roads around the perimeter of the site, and has l not been consistently reported in the monitoring program.

i l All ten 1984 rime ice observations were in the same localized area near the circulating water discharge. Rime ice was observed on vegetation and on vertical surfaces. There were no off-site observations of rime ice in 1984. 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 re, irted on a regular basis in the monitoring program. An " Inspection for Environmental l Impact of Rime Icing" will be made during the 1985 spring growing season of the on-site areas which were subject to the rime ice occurrences.

Analysis shows that the 1984 data had two more observations of

. fog causing reduced visibilities than in 1983 but fewer than in previous l years 1982, 1981, and 1980. As shown below, there were seven observations l in 1984, five in 1983, 12 in 1982, 11 in 1981 and 10 in 1980.

Total observations, visibility Less Visibility Less Than 1/4 Mile ggg, Than 1/4 Mile Downwind Oniv 1944 7 0 1943 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 two times in the five 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.

All the rise ice observations in 1984, 1963 and 1982 were local-ized to the same area where the entrance road crosses the cooling water dis-charge canal. In the pre-operational period there were two observations which occurred during a period of extremely cold weather in January, 1942, which was before fuel loading. There was one observation in 1941 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 time ice reported in 1983, and more were expected in 1984 with both units operating. This has proved to be true and during the prolonged period of cold weather, the ice has persisted and built up.

l An inspection for " Environmental Impact of Rime Icing

• was con-ducted by a consulting plant pathologist. Dr. Barry J. Jacobsen on May 14, 1984. The vegetation in the affected area was inspected and found not to have suffered any observable effects from the rise icing that occurred during the winter of 1963-84. Attachment 5 is a copy of the report of the inspection.

As a result of the occurences of steam fog and rime ice along the on site access road corrective action is being planned. Under consideration

. is a proposal to reroute the channel carrying the condensor cooling water discharge and 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 would be across an on site area which has been previously disturbed by construction. Any action taken on this matter will be evaluated and recorded as specified in Section 3.1 of the EPP.

! The experience through 1944 of preoperational, 1 unit operation i and, in 1944, of 2 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 off'-site incidences of time ice formation.

RESULT 3 OF M&T 1984 3URVEI 0F AREA j INVOLVED IN REPORTED RIM ICE DEPOSITIDW AT TME LASAL12 GENERATING STATIOg Barry J. Jacobsen, Ph.D.

l The area where rise ice was reported on December 19 and 23,1983, January i 10, 11, 17, 19, 20, and 31, 1984, and February 1, 5, 7, 1984 was surveyed for possible effects on vegetation la nooordance with section 4.2.2 (d) er the LaSalle County Station Envireamental preteetles piss. Similar planta in adjacent areas where ne lee was reported were used for esaparisen purposes. .

Areas where rise les was reported were identified by W. Carrel Carpenter one of the trained observers who made the les and fes reports. De identified thtt the area where rise icing eseurred was betuses the airculating water discharge and the parking lot to the north. Weedy plants growing la this area and in adjacent areas which were unaffected by rise ice included, willow,

, eutumn olives,31berean ela, and eettonwood. Comes elever was a porrealal i herbaceous plant conson to both arwes.

Tip diebeek hf willow, cettenweed, 31berose ela, and autumn olive was observed in areas where rise icing was reported and is adjesent areas where  ;

icind was not reported. There was slightly more tip dieback is willow in the area of reported rise icing than la neieleed adjaeest areas. Coasse elever stands and plant health were similar in both areas.

Tip die' beek and death of autumn olive was judged to be due to transplant f ailure associated with the dry senditions of the 1983 greving seases and  !

harsh winter of 1993 84. Tip diebeek of willes and cottoowood is judged to be i

due to the droughty senditions of the 1983 growing sensee and the severe sold.  !

. Page 2 of 2 The observed slight increase in.tip dieback in areas where rise icing was . . . . .

reported was likely due,not to ising effects,but to a delay in plant hardening due to warning from the adjacent discharge wat'er. Plant tissue not adequately sold hardened will usually winter kill. This is particularly true for species such as willow. It is my judgement that icing was not involved since the ice was reportedly gone by noon each der it was reported. Also there was no evidence of sechanical damage aseseisted with ice loads.

It is my opinion that rise icing reported during the winter of 1943 84 had no observable effect on vegetation.

RESULT 3. OF FOLIAR SURVEY OF TEE LASALLE COUNTY GBfERATING STATION FOR RIME i

ICE DEPOSITION DAMAGE i

Prepared for Commonwealth Edison Company by Barry J. Jacobsen, PhD l

l l

i l

0 i

Vegetation in the vicinity of the I4Salle' County Generating Station was surveyed for damage caused by rine ice deposition during the winter of 1984-85 This survey was done in accordance with section 4-2-2(d) of the IaSalle County Station Environmental Protection Plan on the 15th of May, 1985 with the assistance of Mr. B.B. Barriekman of the Commonwealth Edison Company and is the second survey of this site done by Barry J. Jacobsen, Ph.D.

Summaries of the 4th quarter of 1984 and 1st quarter of 1985 of the Fog and Blue Ice Monitoring Program for the IaSalle Station were utilized to identify areas of most likely damage. The survey area is shown in Figure 1 (attached). Also shown in tais figure are specifie sites mentioned in this report. The survey

~

area was sufficiently large so that similar plants could be observed in areas reported to be with and without rise ice.

Site #1_ located around the cooling water discharge was the site where rise toe was reported most frequently during January of 1985. Cottonwood, willow, autumn olive and sweet olover observed at this site did not show evidence of ice damage. .

However, willows loosted north of the cooling water discharge did  !

show more winter injury and oanker disease (Venturia and Cytospora) than other willows in the survey area. Winter injury was dias- l I nosed based on tip dieback and one sided cambium necrosis and bud i death. This winter injury is thought to be due to the warm discharge water delaying the vernalization process. This delay '

in vernalization does not allow the plant tissues to harden off enough to prevent freezing injury when extreme cold ocours. The winter injury noted was relatively minor in nature. Willows growing 25-50 yards north of the cooling water discharge also had wood borer damage.

Autumn olive plantings in this area also displayed.some dieback.

However, the distribution and type of dieback is suggestive of prob-

! less relating to transplanting and plant establishment.

Sweet olover growing in this area showed no evidence of smothering such as would be expeeted from ice damage.

Site #2 located to the west of the cooling water discharge had apple and enk. trees,,uttish showed winter damage. This damage.is thought to relate.te'the vernalization problem mentioned above and not ice damage.J Dogwood steadings at this site showed evidense of transplant damage again in 1983, although most plants show evidense of recovery.

Sweet elover and crown vetah growing at this site.showed no signs of ice smothering.

Site #1 was charsoteristio of orown vetch growing on the banks of the pond containment dike. Growth was excellent and there was little sign of the Volutella canker disease seen in the 1984 survey.

Site #4 was contiguous with observation site #7 used in the fog and rise ice monitoring reports. Diebaok was noted only in a row of old Osage orange trees growing adjaoent to a pasture.

Site M was located at 0.7 miles west of fog and rise ice observation site #8. An old planting of hard maples showed evidense of dieback relating to decay at this abandoned building site. There was no evidense of ice damage.

Conclusion Rime loing was not a factor in vesatation injury in and around the ImSalle County Generating Station during the winter of 1984-85 Diebaak associated with delayed vernalization near the cooling water discharge site can be assosisted with plant operation. However, this damage is minor and is limited only tes whilows which often show winter injury.
