L CATAWBA NUCLEAR STATION VEGETATION MONITORING 1992 INTRODUCTION The Catawba Nuclear Station Non Radiological Environmental Protection Plan (NREP) requires that the Catawba site be monitored for possible effects of cooling tower drif t on vegetation due-to operation of Catawba Units 1 and 2.
This monitoring began the first September following operation of Unit 1 and is to continue in alternate years for three monitoring periods following operation of Unit 2.
Unit I generation began in January 1985. This report describes the results of the monitoring program through 1991.
The Catawba Environmente.1 Report (ER) indicated that the area within the NE and SW sectors approximately 950 feet from the center of the cooling tower yard would receive maximum drif t-deposition. Total dissolved solids (TDS) in the drif t were-projected to be in the range of 350 to 500 mg/1, based on the influent makeup
- water TDS of 60 mg/l and an operating range of 7 to 10 cycles cf -^ncentration.
In addition, sodium hypochlorite, organic biocides, and a ;s persant are periodically used to treat cooling water.
Drift deposition rate calculations in the Catawba ER predicted total solids deposition rates of 2-3 kg/ha/ month (2-3 lb/ acre / month) based on 350 to 500 mg/l of TDS in drift.
The Catawba FEf. indicates that thresholds for visible leaf damage in sensitive plants fall in the range of 10 to 20 kg/ha/ month (9 to 18 lb/ acre / month. Since these thresholds exceeded the projected solids deposition rates at the Catawba site by factors of approximately 5-to 10-fold, drift from the Catawba cooling towers was nnt expected to produce adverse impacts on sita vegetation within or beyond the cooling tower yard or plant boundaries.
4 METHODS The condition of Catawba Nuclear Station site vegetation has been monitored by color infrared aerial photography, supplemented by ground level visual inspection of site vegetation, since 1983. Aerial photography was performed in September 1983 and 1984- (preoperational), in September 1986 (first operational growing season), in September 1987 (second operational growing season), in January 1990 (due to Hurricane Hugo), and in September 1991. Ground level observations were made to support aerial photography. Conclusions based on inspections of the IR photographs and ground level observations through 1989 were presented in the Catawba 1989 Annual Environmental Operating Report (AE0L).
Aerial IR photography was obtained using Kodak IR Type 2443 film at 1:6n00 (1 in - 500 f t) scale on 6 September 1983, on 2 September 1984, on 14 September 1985, on 14 September 10
, on 23 September 1987, on 3 January 1990, and on 14 September 1991.
Vegetation shown in the photographs within a radius of approximately I km of the cooling tower.ytrd was inspected for evidence of dead or damaged foliage which could be related to cooling tower operation. Photographs were interpreted using information provided by Murtha (1972, 1984) as a guide.

~.
RESULTS AND DISCUSSION Operation of the Catawba Unit I cooling towers began in January 1985 (Table 1).
Full scale operation of the cooling towers of both units began in mid-1986 (Table 2). Therefore, site vegetation experienced drif t deposition from full two-unit operation during the 1987 growing season, except during outages (Tables 2 and 3).
Drif t deposition from two-unit operation continued from 1988 through 1991 (Tables 4 and 5).
Forested areas located within 1 km of the towers consist of mixed pine-hardwoods, loblolly pine plantations, mixed shortleaf-Virginia pine stands, and mixed hardwoods.
These stands are described in Duke Power (1975).
Analysis of IR photography revealed no vegetation anomalies that could be attributed to operation of the cooling towers.
Small openings in the forest canopies and individual tree mortalities were apparent from photographs of inside and outside the study area. These occurrences were primarily believed to be the result of damages from Hurricane Hugo and southern pine beetles.
No color variations were observed that could be attributed to vegetation impacts to stands of trees, and there were no patterns observed in the distribution of tree mortalities that would indicate impacts to vegetation resulting from cooling tower drift. Color variations observed in the photographs were associated with differences in types of vegetation cover, not damaged foilage.
Ground inspection of vegetation in the 1-kilometer study area revealed four types of damage to vegetation: Hurricane Hugo damage, southern pine beetle damage, insect damage to apical twigs, and needle-tip necrosis.
In September 1989, Hurricane Hugo passed through the study area, leaving up-rooted, crown-damaged, and trunk-broken conifers and decidiuous trees. This damage remains, resulting in open canopies and fallen trees that are apparent in the infrared photographs.
In 1987 and 1988, loblolly, Virginia, and shortleaf pines in the study area were killed following infestations of the southern pine beetle. An especially heavy infestation occurred within the eastern part of the 1-kilometer study area in 1987; this area was-logged in 1988 to control the infestation, and a salvage harvest cas performed in this area following Hurricane Hugo. " Pockets" of dead pines raselting from this infestation can still be seen inside and outside of the study aren. Some trees within 200 feet of the cooling towers died from southern pine teetle attack. The frequency of occurrence of the infestation in this area was no higher than that of areas not exposed to cooling tower drift; therefore, no association could be made between the beetle damage and-cooling tower drif t.
As mentioned in the 1989 report, needle-tip necrosis or " needle scorch" was observed on loblolly pines in 1987 on the north side of the cooling towers and at-a-distance of about 200 feet from the edge of the towers. This condition was only apparentLon pines closest to the towers, and new growth did not exhibit these symptoms. Young vegetation of these trees examined later in the growing season was healthy.
In 1991, needle scorch on loblolly pine, Virginia pine, shortleaf pine, and eastern red cedar was observed in areas bordering the cooling tower yard.
Browning of about 50% of the surface area of the needles of pines and minor tip browning on cedars was observed on trees that were within 500 feet of the edge of the closest tower.
-There appears to be some sheltering related to the positioning of trees relative to cooling tower drif t.
Conifers prim rily exposed SS36.WPF 2
to drif t on the north to northeast side of the towers were largely affected, whereas trees imediately behind them that did not occupy the canopy or were in the sheltered understory did not normally exnibit. symptoms.
The north to northeast side of the tower is the area most affected, where a relatively high percentage of the trees has symptoms.
Northeast is the predominant wind direction during the growing season, while winds generally blow toward. the southwest during the winter and f all. Areas to the east and south of the towers had a low prevalence of symptoms.
No symptoms were observed on trees greater than 500 feet from the edge of a tower. Mortalities of conifers in this area were believed to be those resulting from past southern pine beetles attacks, and no recent mortalities were observed.
A few dead deciduous trees were observed in the 500 foot area around the towers, but the cause was unknown.
-Insect damage to the main apical twigs of young pines was observed in an area to the southeast, and to a much less extent to the northwest, of the towers and about 500 to 1200 feet from the edge of the towers.
This damage occurred in a majority of the young pines 10-15 feet tall.
While this area is not sheltered from the cooling tower drift, this symptom is likely unrelated to the cooling towers. These pines are located in a retired laydown yard which has poor spoil soils. Adjacent stands of similar age pines on relatively undisturbed soil had no damage.
Damage to vegetation which can be directly attributed to cooling tower drif t was needle-t ip necrosis. This symptom is characteristic of various pollutants, but in this case the damage is likely caused by the deposition of chlorine with the cooling tower drift.
Sodium hypochlorite is used to treat cooling water and would be the likely source of the chlorine.
The next scheduled IR photography will be for September 1993.
Vegetation inspections will be performed to document the seasonal changes in needle-tip necrosis, and to monitor the stands close to the tcwers to see if mortalities result.

Underground Storage Tank Section Ground-Water Protection Division 2600 Bull Street Columbia, SC 29201 ATTENTION:
Stanley Swart: el
SUBJECT:
Catawba Nuclear Station Underground Storage Tanks File No:
CN-707.20
Dear Mr. Swartnel:
On April 15, 1991, SC DHEC was notified of a small amount of diesel fuel contaminated soll found while drilling a cathodic protection well at Catawba Nuclear Station.
Subsequent action after this notification was the following.
First, a tenk tightness test was performed on the four diesel fuel storage tanks near the contaminated soil.
The tanks tested tight on 4/19/91. contains the tank testing results.
On 4/22/91, Mark Berenbrok of SC DHEC was informed about the tank testing results and about our future groundwater well monitoring plans.
Mark's guidance was to submit this tank testing data along with the groundwater monitoring well data after the groundwater monitoring well data became available.
Second,'a groundwater monitoring well was installed at this location and developed.
This well and two other nearby monitoring wells were then sampled and the samples submitted for semivolatile organic analysis,
_ The sample results recently became available and are Attachment 2.
Well locations in the backfilled area are shown on Attachments 3, 4, and 5.
The sample analysis-showed that in the backfilled area containing the diesel fuel tanks, only newly installed Monitoring Well 14 (MW-14) has semivolatile -organic
-contamination.
The two other nearby monitoring wells did not contain any semivolatile organic contamination.
The semivolatile organics in MW-14 correlate with aced diesel fuel.
_... _.,-.... ~. _ _.. _ - _
. _.. _... _ _. _ _ _.. _ - _ _. ~.. ~ _. _. _ _. _ _ _ _ -. _. _
4 Since the diesel fuel etorage tanks - tested tight and the-analysis showed the contamination 1s-aged diesel fuel localized in a small portion of the backf 'lled. area, it appears that this soil contamination may have occurred during tank installation.
We intend to analyze these three groundwater-monitoring wealls _ within the next 6 months to ensure that the groundwater contamination nas not increased or spread.
If there are any questions about this letter, please contact me at (704) 373-2758.

Dear Mr. Wiley,
A tank integrity test was performed on the above storage tenkis) using the LEAK COMPUTER system. This test was performed in accordance with the precision test requirements of EPA-40-CFR part 240 subpart C, as sell as the manufacturers recommended procedures.
The results of the test are given below and indicate whether the tankt s ) with the associated piping (with the exception of pressurized piptrg passed or failed the Integrity criteria.
Included is the computer printout of the test data, indicating the average leak rate and the confidence level as shown at the end of each strip chart.
Ints information is stored in a permanent file, if future verification is needed to confirm the tank integrity at the time of the test.
