Gentlemen: 

The Poplar River Bilateral Monitoring Committee continues to address those 
responsibilities assigned to it by Governments under the Poplar River Cooperative 
Monitoring Arrangement dated September 23, 1980. Water quantity, water quality 
and air quality data of significance to impacts at the International Boundary 
were exchanged between countries on a quarterly basis. The monitoring information 
exchanged were in accordance with the locations, frequency and parameters detailed 
in the Technical Monitoring Schedule. 

The Committee has examined and evaluated the monitoring for 1982 and concludes 

the measured conditions fall within accepted objectives or norms for the parameters 

involved. No major trends are yet apparent at the International Boundary. 

This second annual report to Governments covers the calendar year 1982 , roughly 
corresponding to the second year of operation of the Saskatchewan Power Corporation 
300 MW coal-fired thermal generating stations located on the East Poplar River. 
The results of the monitoring program are summarized and narrative descriptions 
relative to pre-project conditions, and guidelines for specific parameters that 
may have been developed as joint activities under International Joint Commission 
references are included. 

The Committee, in accordance with recommendations of the International Joint 
Commission has devised a flow-weighting scheme for boron and total dissolved 
solids. The results are presented in this report. 

Yours sincerely.

'^*-' ■ ; 1982 HIGHLIGHTS 

The first 300 MW coal-fired electrical generating unit at the Saskatchewan 
Power Corporation Poplar River Power Station began commercial operation 
in July 1981. 

The quarterly exchange of monitoring information collected by both countries 
was carried out during I982. In general, the frequency, location and type 
of information exchanged met the requirements identified by both countries 
in the Technical Monitoring Schedule. 

The United States received a continuous discharge in the East Poplar River 
throughout the year and in addition was entitled to an on demand release of 
up to 1,230 cubic decameters between June 1, 1982 and May 31, 1983. As of 
December 31, 1982 this release had not been requested. The snowmelt runoff 
was much above normal in I982 and resulted in large spill volumes from Cookson 
Reservoir. Recorded flow below Cookson Reservoir was less than the minimum 
discharge recommended by the International Joint Commission (IJC) 19 percent 
of the time. 

The ground-water drawdown associated with coal seam dewatering was shown to 
have no impact closer than one-half mile north of the International Boundary. 
Boron and total dissolved solids (TDS) vary widely in the ground water with 
generally poorer quality water in the lower aquifers. 

Boron and TDS in the East Poplar River were below the long-term and short- 
term objectives recommended to Governments by the IJC. There was no discern- 
ible trend from pre-project conditions. Water quality met the objectives for 
other parameters recommended by the International Poplar River Water Quality 
Board to the IJC with one exceedence being observed for total zinc. 

Water quality in piezometers near the Saskatchewan Power Corporation ash 
lagoons was highly variable, with questionable results reported. Steps are 
proposed by the Committee to improve results. 



1. 



Ground-water seepage from the ash lagoon was computed to be less than 
the construction standards established by Saskatchewan. 

Plant stack emissions did not cause or contribute to violation of Montana, 
Saskatchewan and the United States ambient air-quality standards.

INTRODUCTION 

The Poplar River Bilateral Monitoring Committee was authorized by the 
Governments of Canada and the United States under the Poplar River Cooperative 
Monitoring Arrangement dated September 23, I98O. A copy of the Arrangement 
is attached to this report as Annex 1. 

The Committee is composed of representatives of the Government of Canada, 
Province of Saskatchewan, Government of the United States of America, and 
State of Montana. In addition to the representatives of Governments, two 
ex-officio members who are local representatives of the State of Montana and 
Province of Saskatchewan participate in the activities of the Committee. 
During I982 the members and ex-officio members of the Committee were: 



Mr. R. C. Averett Mr. D. A. Davis 

U.S. Geological Survey Environment Canada 

Co-chairman, U.S. Section Co-Chairman, Canadian Section 



Mr. T. E. Gallagher Mr. G. W. Howard 

Governor's Office Saskatchewan Environment 

Montana Member, U.S. Section Member, Canadian Section 



Mr. C. W. Tande Mr. J. R. Totton 

Daniels County Commissioner Reeve, R.M. of Hart Butte 

Ex-Officio Member, Montana Ex-Officio Member, Saskatchewan 

The Committee met in Regina, Saskatchewan in March I982 to prepare the 
1981 Annual Reports to Governments. An ad hoc technical group met in Denver, 
Colorado in December I982 for the purpose of reviewing monitoring information, 
quality assurance programs, and the progress to date on development of flow- 
weighting procedures. The contents of the I982 report to Governments was also 
discussed. 

The responsibilities of the Committee include an ongoing quarterly exchange 
of the results of water quantity, water quality and air-quality monitoring 
programs being conducted in Canada and the United States at or near the 
International Boundary. The monitoring program is in response to the con- 
struction of Saskatchewan Power Corporation's coal -fired thermal generating 



3. 



station near Coronach, Saskatchewan and to the concerns of transboundary 
impacts. The exchange of monitoring information was initiated with the first 
quarter of I98I, and is an expansion of the informal quarterly information 
program instituted between Canada and the United States in 1976- The data 
exchanged are documented in a Technical Monitoring Schedule attached as 
Annex 2. The data are available for public review at agencies of the parti- 
cipating governments or from Committee members. 

The Committee is also required to prepare an annual report to Governments 
which draws to the attention of Governments any definitive changes in the 
monitored parameters based on evaluation of the data made available by both 
countries. The Committee has decided to report to Governments on a calendar 
year basis. The first report covered I98I and was issued in March I982. 
Issuance of this I982 report roughly corresponds to the second year of 
operation of the first 300 MW Unit of the coal-fired thermal electric gener- 
ating station operated by Saskatchewan Power Corporation on the East Poplar 
River near Coronach, Saskatchewan. Subsequent sections of this report 
summarize the findings and comment on the results in relation to pre-project 
conditions, and to objectives or standards recommended 'by the International 
Joint Commission. 

Another responsibl I tiy of the Committee is to review the adequacy of the 
monitoring programs in both countries and make recommendations to Governments 
on the Technical Monitoring Schedule. The Technical Monitoring Schedule 
proposed for I983 is attached as Annex 2, and the concurrence of Governments 
with the proposed Schedule Is requested. It can be expected that the 
Committee will continue to review and propose changes to the Technical 
Monitoring Schedule In future years as Information requirements change. 



POPLAR RIVER POWER STATION 

Operation 

The first 300 MW unit was commissioned in June 1981 and commenced commercial 
operation July 1, I98I. The unit operated for the full twelve months of 
1982. The station's electrical production statistics for the period were: 

Hours of operation 7310 

Gross MWh generated l.Sy't.SOO 
Availability (hours) 83. '♦S^ 

Capacity Factor 76.6?^ 

Number of startups 35 

Coal consumed 1,689,624 tonnes 

Oil consumed 5, 85'*, '•83 litres 

Failures in the ash-collection system resulted in eight spills; the last of 
which occurred on August 6, I982. With the exception of one case when an 
estimated two cubic meters entered the reservoir, all ash spills were contained 
on site. 

Spill containment structures were completed in the fall and are now operational. 

Construction 

Construction of the second 300 MW unit at the Poplar River Power Station was 
at a virtual standstill from May to December I982 due to a construction 
trades strike. Boil out and acid clean for the second unit was scheduled for 
February 1983; first fire on coal May 1983; and commercial operation is scheduled 
for July 1983.

SURFACE WATER QUANTITY 



Natural Flow 



The natural flow in the Poplar River basin was well above normal in 1982, 
assuming the recorded flow of the Poplar River at International Boundary is 
a good indicator of basin runoff conditions. Snow accumulation prior to 
runoff was above normal, and combined with a late melt and rapid warming, 
resulted in a maximum instantaneous discharge of the Poplar River that was the 
5th highest on record; 113 cubic meters per second (m /s) on April 13, 1982. 

The volume of runoff in the Poplar River between March 1 and October 31, 1982 

was 29,500 cubic decametres (dam ) compared to a long term mean volume of 

3 
17,200 dam . The recorded runoff volume of the Poplar River during the March 1 

to May 31 period, used as an indicator in setting the minimum and on demand 

releases in the East Poplar River under the International Joint Commission 

apportionment recommendations, was 27,^00 dam . 

Minimum Flows 



Based on the apportionment recommendations of the International Joint Commission, 

the United States would be entitled to a minimum discharge of 0.028m /s from 

3 3 

January until May 31; O.O85 m /s from June 1 until August 31; and 0.057 m /s 

from September 1 to December 31, 1982 on the East Poplar River at the Inter- 
national Boundary. This stream regime is designed to enhance instream environ- 
mental values during the summer period in years when spring runoff is high. 

The minimum discharge in the East Poplar River during the period January 1 to 

■J 
May 31 was 0.023 m /s, with this flow occurring from January 16 to January 25. 

During the January to May period the recorded flow was marginally below the 
recommended minimum flow for 46 days, all under ice conditions. Cold tempera- 
tures during this period caused large accumulations of ice in the channel 
between Cookson Reservoir and the International Boundary which reduced flows 
to less than what had previously been measured. The flow was below the recom- 
mended minimum for 2k days in August when a discharge of 0.076 m /s was recorded 
on August 6 and August 9 to 31. The minimum flow during the period September 1 



3 

to December 31, 1982 was 0.076 m /s, well above the recommended flow of 

0.057 m /s for that time period. During the year the recorded flow was 
below the recommended minimum flow approximately 19 percent of the time. 
However, the average flow for each of the three periods exceeded the recommended 
minimums. 

The hydrograph of the East Poplar River at the International Boundary is 

depicted in Figure 1, along with the International Joint Commission recommended 

minimum flows. As can be noted from the hydrograph, there was a large and 

3 
sustained snowmelt runoff during I982. Of the total volume of 29,000 dam 

3 
recorded for the year, 22,500 dam occurred in April. 

Reservoir Storage 

Cookson Reservoir Was at elevation 751.867 m on January 1, rising to 753-026 m 
during the peak of the snowmelt runoff on April 15. The reservoir level was 
held steady, near full supply levels for several months with the highest 
level for the year recorded on June 2 at elevation 753-160 m. The reservoir 
declined slightly over the summer months and the reservoir level at year end 
was 752.681 m. The corresponding volumes of stored water were: 

Full Supply Level 43,^00 dam^ (elevation 753-000 m) 

3 
January 1 35,000 dam 

April 15 't3,600 dam^ " 

3 
June 2 44,700 dam-^ 

3 
December 31 41,000 dam"^ 

3 
The increase in storage over the year was 6,000 dam , with only small reservoir 

drawdown in the summer and fall, primarily because coal-seam dewatering dis- 
charge entering Cookson Reservoir through Girard Creek was of sufficient 
volume to help offset evaporative losses and releases from the reservoir. 
Because of the near full supply level conditions at the end of the year, the 
reservoir will not have a major modifying influence on the I983 spring runoff 
in the East Poplar River.

Boundary. 



On Demand Release 



The 1982 runoff volume on the Middle Fork of the Poplar River at the Inter- 
national Boundary from March 1 to May 31 was 27, ^^tO dam . Based on the 
apportionment recommendations of the International Joint Commission, the 
United States would be entitled to an on-demand release of up to a maximum 
of 1,230 dam-^ during the period from June 1, I982 to May 31, I983. As of 
December 31, 1982 no request had been received for this on-demand release. 
All past commitments for on-demand releases have been met. 



SURFACE WATER QUALITY 

Surface water quality has been assessed using the data exchanged under the 
terms of the Technical Monitoring Schedule. Additional data on conductivity, 
collected by the United States Geological Survey from March to October, was 
used in regression equations for determining flow-weighted concentrations. 

Flow-Weighted Concentrations ■ 

In order to assess compliance of the East Poplar River quality with the 
recommended IJC objectives for boron and TDS, flow-weighted concentrations 
must be computed. The IJC report recommends: (1) a long-term objective 
computed as a five-year moving flow-weighted concentration, and (2) a short- 
term objective for any given year computed as a three-month moving flow-weighted 
concentration. The objectives apply to the March to October period which the 
IJC determined to be the maximum time interval over the annual cycle in which 
water may be used for irrigation purposes. Flow-weighted concentrations have 
been computed using the following concept: 



^0 = 



C,Q, + C2O2 + C3Q3 + . . . C^Q^ 
Q, + Q2 -^ O3 +. . . . 0^ 



where C^. = Flow-weighted concentration 



C. = Instantaneous concentration at mean daily flow Q. 

Q, = Mean daily flow for C, 

n = Last observation for the period of record 



Consideration was given to using different combinations of daily and montlily 
flows, instantaneous and mean concentrations, and advancing the time period 
for computing the moving averages either by one day, month or year. The 
techniques used and the results can be obtained by writing the Canadian 
Chairman of the Poplar River Bilateral Monitoring Committee. 

Flow-Weighted Concentrations for Comparison to the Long-Term Objective 

The Committee has adopted the approach that for the purpose of determining 
compliance of the East Poplar River Water Quality with the recommended IJC 
long-term objective, the data are best presented as a five-year moving average, 
advancing one month at a time. 

It should be noted that in addition to the instantaneous sample data, daily 
boron and TDS concentrations have been calculated using a regression with daily 
electrical conductivity values. Eventually, the long-term average will be 
computed using the approximately 240 data points from each annual eight-month 
irrigation period rather than from the present sixteen (tVvo samples per month). 

Flow-Weighted Concentrations for Comparison to the Short-Term Objective 

To determine compliance of the East Poplar River boron and TDS quality with 
the recommended short-term IJC objective, the Committee adopted the approach 
of computing three-month (90 day) moving flow-weighted concentrations advancing 
one month at a time while dropping the first month in the time period. This 
method has been applied to the entire period of data record and was based on 
data from instantaneous samples. The only exception to this was during 1982, 
when calculated daily boron and TDS were obtained using a regression with 
electrical conductivity. These 1982 calculated concentrations were then used to 
compute the short-term (90 day) moving flow-weighted concentrations while advancing 
one day at a time throughout the period March to October. 

Data Compatibi 1 i ty 

Environment Canada and the United States Geological Survey improved their 
knowledge on data compatibility by exchanging and splitting water samples 



10. 



during June 1982. For most relevant parameters reported there was agreement 
between agencies. The TDS and boron data compared extremely well, but some 
discrepancies in pH and electrical conductivity results remained; the reason 
for these discrepancies are being investigated. The agencies will be repeating 
the entire intensive quality-control project, with some minor improvements in 
project design during I983. 

East Poplar River at international Boundary 

Table 1 presents the water quality objectives recommended by the IJC and 
the larger set of objectives recommended to the IJC by the International Poplar 
River Water Quality Board. The corresponding number of samples collected for 
the East Poplar River near the International Boundary by governments are also 
shown in Table 1 . 

t' 
Boron 

The two principle data bases (USGS and Environment Canada) report dissolved 
boron, although it is believed the IJC recommended objective is for total 
boron. The Committee has taken the position that total and dissolved boron 
concentrations are essentially equal and is utilizing the more commonly 
reported dissolved boron for the purpose of monitoring and determining com- 
pliance with the IJC recommended objectives. 

The long-term five-year moving flow-weighted concentration is presented in 
Figure 2. Note that each point is plotted as the midpoint of a five-year 
period, advancing one month at a time throughout the data set, which consist 
of March to October data. The five-year moving flow-weighted concentrations 
for boron have not exceeded 1.5 mg/L, which is below the recommended long-term 
objective of 2.5 mg/L. The sharp decline occurring in 1979 resulted because 
of the above normal snowmelt runoff in April I982, which had a boron level of 
0.73 mg/L. 

The three-month moving flow-weighted concentrations for boron have not exceeded 
the recommended short-term objective of 3^5 mg/L for any given year as shown in 
Figure 3. The trend in each annual curve is similar. As autumn approaches, 
the boron three-month flow-weighted concentrations gradually rise as the

data are also presented using daily boron concentrations estimated using 

2 
the regression equation: Boron = 0.001^7 x Conductivity - 0.2538; r = 0.82. 

Based on sample data, the maximum boron concentration during I982 for the 
irrigation period (March through October) was 2.0 mg/L on March 9th. For 
comparison, the maximum concentration was 1.93 on March 3 and 19, 1982 using 
the regression equation. The maximum sample concentration of boron for the 
entire year was 2.2 mg/L on February 11, I982. 

Total Dissolved Solids 

The long-term five-year moving average for TDS ranged from 529 to 753 mg/L, 
never exceeding the recommended long-term objective of 1,000 mg/L (Figure 2). 
The maximum sample concentration (during the irrigation period) during I982 
was 1,050 mg/L recorded on September 27, whereas the maximum for the entire 
year was 1,210 mg/L recorded on February 11, I982. 

Based on the available data, the recommended short-term objective of 1,500 mg/L 
has not been exceeded during 1975 to 1982. The maximum three-month flow-weighted 
concentrations for the period of record occurred during the period of June to 
October I98O when a level of 971 mg/L was measured. During the irrigation 
period of I982, the maximum three-month flow-weighted concentration was 905 
or 891 mg/L depending on whether the method of computation used sample data or 
estimated concentrations, respectively. The regression equation for estimating 
daily total dissolved solids concentrations is: 

TDS = 0.647^ (conductivity) - 4.018; r^ = 0.9^ 

Other Water Quality Characteristics 

With the exception of zinc, the multi-purpose objectives recommended by the 
IJC International Poplar River Water Quality Board for the East Poplar River 
near the International Boundary were achieved during I982 (Table 1). The 
concentration of zinc exceeded the recommended objective of 0.03 mg/L in 
one of sixteen samples. The mercury content of the river is still uncertain 
because the two principle data bases do not compare. The Environment Canada 
data indicated that the mercury content was at or below the analytical 
detection limit of 0.02 ug/L. The United States Geological Survey data appear 



15. 



to reflect possible sample contamination and have been withdrawn until their 
reliability is determined. Investigations into identifying possible sources 
of contamination are being conducted by the United States Geological Survey. 
Uranium data obtained by the Environment Canada show that concentrations in 
the East Poplar River near the International Boundary are typical of background 
concentrations found in surface waters. The concentrations are below the 
Canadian Drinking Water Quality Guideline of 20 ug/L. 

An assessment of the metal characteristics of the river ecosystem can be 
improved utilizing collaborative biological data. Environment Canada plans 
on conducting studies of metals in water, sediment and biota of Cookson 
Reservoir during 1983. It is interesting to note that during low-flow periods, 
the East Poplar River water quality is influenced by ground-water inflow in 
the area immediately below the reservoir. This is substantiated by the 
higher sulphates in the East Poplar River than what was observed in the reser- 
voir itself during these low-flow periods. A typical example is the August 
sulphate concentrations of 292 and 108 mg/L at the International Boundary and 
Cookson Reservoir sites, respectively. 

Cookson Reservoir 



Samples collected quarterly by Saskatchewan Environment indicate that the TDS 
content of Cookson Reservoir discharge was predominantly less than 1,000 mg/L. 
The boron concentrations approached 1.85 mg/L during February and were as low 
as 0.73 mg/L during May. There was variability in chemical characteristics 
between the upper and lower ends of the reservoir. The rather sparse data 
set does not, however, permit an evaluation of the variations between the 
different sampling sites on the reservoir. No unusual quality characteristics 
have been observed. Cookson Reservoir remains a Fish-For-Fun zone, largely 
because no information concerning mercury in fish were collected in 1982. 
Environment Canada intends to conduct a comprehensive survey during 1983 to 
determine the levels of mercury (and other metals) in fish, water, and sediment 
within the reservoir ecosystem.

GROUND WATER QUANTITY 

Coal Seam Dewatering Saskatchewan 

Data on ground-water levels were exchanged for five piezometers in Sasi<atchewan 
near the International Boundary for the purpose of monitoring drawdown due to 
coal seam dewatering at the Poplar River Mine, A decrease in 198z of 0.56 meters 
was observed in piezometer 52, closest to the mine. Levels at the four other 
piezometers increased from 0.13 to O.AO meters. 

A map of the cone of depression, prepared for the Saskatchewan Department of 
Environment Is shown in Figure k. Near the mine site the drawdown cone exceeds 
20 meters. The cone of depression extends south to about one-half mile of the 
International Boundary. The Committee will maintain close scrutiny of any 
expansion of the cone of depression, and in I983, will endeavor to undertake 
activities to relate the initial ground-water model to the monitoring results. 
That is, the Committee recommends that the United States initiate water-level 
monitoring near the International Boundary south of the point of maximum 
expansion of the cone of depression. Additional test wells may be required. 

Montana 

Ten wells which penetrate the following formations were monitored and sampled 
in the United States portion of the East Poplar River basin near the International 
Boundary. The wells penetrate the following formations: Alluvium (0-15 meters 
in thickness); Flaxville (0-26 meters in thickness); Fort Union, including the 
Hart coal seam, (2kk plus meters in thickness); Fox Hills (26-36 meters in 
thickness); Hell Creek (67-85 meters in thickness). Water level observations 
were made quarterly. Four of the wells were equipped with continuous water- evel 
recorders. 

Small increases and decreases in water levels have occurred in all wells during 
the two and one-half year observation period, but no trends are noticeable. 
During April and May I982, small increases were noted in shallow wells 5, 6, 
and 10, probably due to above average precipitation. Dewatering of the Hart 
coal seam north of the International Boundary has, to date, no apparent effect 
on any of the U.S. observation wells.

GROUND WATER QUALITY 



Montana 



The ten observation wells on the United States side of the International 
Boundary have been sampled during October on an annual basis since I98O. 
Wells 2, 3, and h have a casing diameter of 3-8 centimeters and this small 
diameter has precluded adequate pumping for obtaining a reliable sample. Thus, 
analytical results from these wells are considered unreal iable and have not 
been included in characterization of the water quality. Wells 5-11 have larger 
diameter casings and sufficient pumping prior to sample collection was possible 
to provide reliable water-quality results. 

Throughout the sampling period the wells had little change in their major ion 
water chemistry (Figure 5). Wells 6 and 7, from the Hart coal seam, were 
similar in major ion chemistry with the cations dominated by calcium and 
magnesium with sodium contributing less than 30 percent of the total. The 
anions were strongly dominated by bicarbonate. Total dissolved solids concen- 
trations were near 500 mg/L and boron concentrations were near 0.8 mg/L. Water 
from alluvial wells 5, 7, and 8 had similar chemical compositions as those 
from the Hart coal seam, especially with respect to anion ratios and TDS concen- 
trations. The cation ratios and boron concentrations were slightly more 
diverse. Waters from wells that penetrate the Fort Union and Fox Hills-Hell 
Creek aquifers (wells 9 and 11, respectively) had a sodium bicarbonate type 
water. The total dissolved solids concentrations from both wells was near 
900 mg/L and the boron concentrations were slightly higher than 1.8 mg/L. 

Concentrations of nitrate nitrogen were usually low except for alluvial well 
number 5 where the 3 samples (1980, I98I , and I982) ranged from I.8I to 
7.58 mg/L. The maximum concentration was below 10 mg/L which is the recommended 
upper limit for domestic water supplies. Fluoride concentrations were always 
less than 1 mg/L except for well number 11 where concentrations up to 3.1 mg/L 
were measured. 

Trace element concentrations from all samples met drinking-water standards. 
But, the following elements showed slightly higher concentrations in the wells 
listed as compared to the average of all wells.

Ground-water quality was determined in 14 of the 18 piezometers included in tiie 
monitoring scliedule. The remaining four piezometers were dry at the time of 
sampling (October). Scatter diagrams of concentrations plotted linearly against 
time were used to interpret all available data. The following parameters showed 
wide concentration variability in seven or more piezometers: specific conduc- 
tivity, calcium, iron, arsenic, copper, aluminum, lead, zinc, color, and total 
dissolved sol ids. 

Piezometer C712B (Station 2a in oxidized till) showed increasing trends from 
seven parameters: barium, calcium, chloride, sulphate, strontium, uranium, 
and vanadium. Piezometer C726B (Station 8a in mottled till) showed increased 
concentrations for four parameters: barium, conductivity, manganese, and lead. 
Piezometer C726E also showed increased concentrations for five parameters: 
calcium, lithium, magnesium, total alkalinity and total hardness. These three 
piezometers are located next to the ash lagoons and the changes may be due to 
seepage. However, the values fluctuate too much to allow any conclusion to be 
made at this time. 

The question of sampling, analytical precision, and variability of the local 
ground-water quality was raised by the Poplar River Bilateral Monitoring 
Committee in its I98I Annual Report. A follow-up investigation by the 
Saskatchewan Power Corporation was undertaken in 1982. The data are still 
variable and it is not clear whether the results represent the natural state 
of ground-water quality or are the result of problems in sampling handling, 
or methods at the laboratories. It is proposed, therefore, that the Committee 
conduct more investigations in I982 into the question of data variability. 



21. 



ASH LAGOON QUALITY AND QUANTITY 

Seepage calculation for ash lagoons No. 1 and 2, and the polishing pond were 
made in the fourth quarter of I982 and subsequently reviewed by the consultant 
who developed the initial calculations, Thomas A. Prickett, P. Eng., of Urbana, 
Illinois. The effect of No. 2 lagoon was considered since approximately 0.5 
meters of water now covers the bottom of this lagoon. Total seepage from the 
lagoons (including polishing ponds) was calculated to be 0.182 liters/second. 
Flow to Cookson Reservoir from the oxidized till adjacent to the polishing 
pond was zero. The leachate front has advanced O.65 meters since the pond was 
first filled. The leachate flow in the Empress formation to the Poplar River 
was zero. The leachate front in the Empress formation has now advanced to a 
point 261.0 meters to the south of the ash lagoons. 

Permeability of the liners has remained in the same order of magnitude (10 cm/s) 
as orginally calculated by T. A. Prickett. This was confirmed by computed lower 
seepage rates. 

The concentrations of the ions in the ash lagoons and polishing ponds were 
expected to increase with time. This did not occur for all ions. The concen- 
trations of 11 parameters increased in the polishing pond water, whereas 5 
parameters in the ash lagoons increased in concentration. These measurements 
provide a basis for comparing future changes in adjacent ground-water quality. 
All samples should be filtered so as to minimize the effect that suspended 
particles may have on the analyses. In addition, the Committee recommends 
split samples be collected and analyzed annually by United States and Canadian 
laboratories. In recognizing the importance that fly-ash quality has on 



22. 



water quality, the Committee also recommends that samples of the ash in the 
ponds be analyzed on an annual basis. 

Parameters that increased in concentration in the ash lagoons were: boron, 
fluoride, molybdenum, and strontium. The pH also increased. In addition, 
increased concentrations were observed in the polishing pond for barium, 
chloride, selenium, sodium, sulphate, and vanadium. 

Ground-water elevations were monitored in 66 piezometers in the vicinity of 
the ash lagoons and in the area southward to the International Boundary. Six 
wells were dry at the time of measurement in October 1982. 

Increased ground-water elevations were observed in 52 piezometers and decreased 
elevations were observed for six piezometers (6a. , 8a-, 8c,, 8c„, 9b_ and OSS'*). 
The range of increases were 0.11 to 1.6 meters in the till and 0.1 to 0.85 meters 
in the Empress formation. The water level decline was most pronounced in piezo- 
meters 8c. (4.31 meters) and 9b„ (4.08 meters) and are anomalously large considering 
the water level readings reported for the third quarter of 1982. These two 
piezometers are reported to have low recovery characteristics. 



23. 



AIR QUALITY 

Montana 

The State of Montana continued to operate three air monitoring sites in the 
Poplar River area of Montana during I982. The parameters monitored include: 
sulphur dioxide, Beta scattering coefficient, total suspended particulates, 
sulphates and nitrates. 

During I982, sulphur dioxide concentrations remained below both Montana and 
United States ambient air-quality standards. The maximum one-hour concentration 
of 6.0 parts per hundred million (pphm) was recorded at the International Boundary 
site during September. This concentration is approximately one-eighth of the 
Montana standard. The highest Z't-hour concentration of 2.0 pphm occurred in 
March, also at the International Boundary site. The Montana 2A-hour sulphur 
dioxide standard is 10 pphm. A comparison of sulphur dioxide concentrations 
with Class II Prevention of Significant Deterioration increment, demonstrates 
that the 24-hour concentration is the averaging time which consumes the most 
increment. The 2.0 pphm 24-hour average at the International Boundary site 
would consume 57 percent of the available increment. 

The Montana 24-hour standard for total suspended particulates was exceeded 

on May 5, I982. On that date a concentration of 234 micrograms per cubic meter 

■I 
(ug/m ) was recorded at the International Boundary site. An examination of 

the sample and Montana meteorological data indicated that May 5, 1982 was 

characterized by high winds, which resulted in excessive wind-blown dust off 

agricultural fields. This concentration also exceeded the United States 

secondary standard but did not exceed the health-based primary standard. 



2A. 



Although several 24-hour concentrations of total suspended particulates exceeded 
the Class II Prevention of Significant Deterioration increment, it is likely 
that the Sasi<atchewan power plant is only a minor contributor. The major source 
of particulates is fugitive dust from agricultural fields and unpaved roads. 

The annual geometric and arithmetic means for total suspended particulates 
returned to the low levels experienced prior to I98I; a drought year that was 
associated with frequent dust storms. The Montana Air Quality Bureau considers 
that the I982 values are close to normal. These particulates are also well 
below Montana and United States ambient air-quality standards. In addition, 
the sulphate and nitrate levels were low and typical of remote unpolluted 
areas. Visibility measurements taken at the International Boundary site show 
an average Beta scattering coefficient of 1.9 x 10 per meter for I982. 
Although the Poplar River area is designated Class II under the Prevention of 

Significant Deterioration increment program, the average scattering coefficient 

-5 -5 

of 1.9 X 10 per meter is well below the Montana standard of 3 x 10 per meter, 

which applies only to pristine Class I areas- 
Saskatchewan 



Ambient sulphur dioxide monitoring began near Coronach in July 1979- To date 
a few detectable concentrations have been recorded at this site. The highest 
concentration recorded in I982 was 3-9 pphm on June 4, which is below Saskatchewan 
Environment's one-hour air-quality standard of 17 pphm. 

The 24-hour average suspended particulate concentrations in Coronach exceeded 
Saskatchewan Environment's air-quality standards on three occasions in I982. 



25. 



Weather Information for the three days indicates that strong winds were blowing 
from a northerly direction. The power plant was not likely the source of 
these elevated levels, but quite probably dust from fields north of the 
monitoring site was responsible. The I982 annual geometric mean concentration 
for suspended particulates was below the Saskatchewan standard of 70 ug/m . 

In-stack monitoring results have shown variability due to plant operation and 
difficulties and changes in coal quality. In addition, considerable monitor 
downtime was experienced during the year; however, instrument serviceability 
has improved in the last half of I982. 

On the occasions when bunker oil was used as a fuel at the plant, unusually 
high stack opacities were the result. This is attributed to a coating effect 
which the oil has on the precipitator. Dally average opacities have generally 
ranged from 20 to kO percent, with the lowest values occurring during uninter- 
rupted coal firing. The SPC has an ongoing program of precipitator tuning and 
experimentation with electrode and plate rapping sequences which has Improved 
the performances of the unit. Precipitator efficiency was measured at greater 
than 99 percent In June of I982. 

In-stack nitrogen oxides concentrations remained relatively constant, averaging 

■3 
about 700 milligrams per cubic meter (mg/m ) . Daily average sulphur dioxide 

3 3 

concentrations have ranged from about 2000 mg/m to about 4000 mg/m , corresponding 

to changes In the sulphur content of the coal. The relationship of sulphur 

dioxide emissions to the firing with bunker oil is being investigated.

COOPERATIVE MONITORING ARRANGEMENT 



TECHNICAL MONITORING SCHEDULES 



CANADA - UNITED STATES 



March 8, 1983 
PREAMBLE 

The Technical Monitoring Schedule lists those water quantity, water quality 
and air quality monitoring locations and parameters which form the basis for 
information exchange and reporting to governments. The structure of the 
Committee responsible for ensuring the exchange takes place is described in 
the Poplar River Cooperative Monitoring Arrangement. 

The monitoring locations and parameters listed herein have been reviewed by 
the Poplar River Bilateral Monitoring Committee and represent the basic 
technical information needed to identify any definitive changes in water 
quantity, water quality and air quality at the International Boundary. The 
Schedule was initially submitted to governments for approval as an attachment 
to the 1981 report to governments. Changes in the sampling locations and 
parameters may be made by governments based on the recommendations of the 
Commi ttee . 

Significant additional information is being collected by agencies on both 
sides of the International Boundary, primarily for project management or 
basin-wide baseline data purposes. This additional information is usually 
available upon request from the collecting agency and forms part of the pool 
of technical information which may be drawn upon by governments for specific 
study purposes. Examples of additional information are water quantity, water 
quality, groundwater and air quality data collected at points in the Poplar 
River basin not of direct concern to the Committee. In addition, supplemental 
information on parameters such as vegetation, soils, fish and waterfowl 
populations and aquatic vegetation is also being collected on either a routine 
or specific studies basis by various agencies.
