Vlad, 

Attached you will find the data and procedures used to calculate the FGD limits we discussed 

with OMB at our recent meeting. Please don't hesitate to contact me or Liz Aldridge (804-788-

Procedures Used for Alternative Limit Calculations 

Additional self-monitoring data over a period of years were submitted to UWAG from 

several plants for which EPA had already conducted sampling episode reports. These 

data were included in the revised limit calculations. 

2 All original data either used or considered for use for limit calculations are included on 

the "daily FGD Effluent" data sheet. This includes all EPA SER and CWA 308 data, as 

well as available self-monitoring data for each plant. 

3 The full dataset contains some outliers (i.e., statistically significantly higher values). 

High outliers would artificially raise the limits, and could be indicative of plant upsets, 

but in the case of FGD wastewater the outliers may also be values indicative of proper 

operations, given the inherent variability of FGD wastewater. For the purposes of this 

analysis, URS subjected high results to a four standard deviation test; if the result was 

outside of four standard deviations high, it was discarded. Nonetheless, the discarded 

values likely represented proper operational conditions and not upsets. 

4 Unusually high detection limits were handled as indicated for each parameter. 

5 EPA calculated monthly averages based strictly on four successive values, regardless of 

the month in which the sample was collected. This appears to defeat the purpose of 

collecting data from several separate months. It also biases the monthly average 

variability, since for arsenic and mercury, there were only two monthly average data 

points available to EPA for calculating the proposed limits. For example, if EPA 

averaged the first four data points (all taken on successive days during the same month), 

they would have to average the last four single samples from four different months 

together, masking long-term variability. With plenty of data available, UW AG calculated 

each monthly average only for samples analyzed within each month for each parameter. 

This is much more representative of variability for the monthly averages. This also 

reflects actual operating and permit conditions, under which a permit holder must report a 

monthly average for each calendar month, regardless of whether there is one or more 

analyses for that month. 

6 Non-detected data-EPA made the assumption in its calculations that non-detected data 

had near-zero variability. EPA took the proportion of data that was non-detected and 

equated the variability to zero. This was a major issue for arsenic, where a significant 

proportion of the data was NO at various reporting limits. Nondetected data do not 

actually have zero variability, it is just obscured due to the analytical limitations. Using 

non-detected data at the reporting limit already lowers the variability of the data (same 

result over and over is not variable), even without equating it to zero. URS used the nondetected results at the reported face value. 

7 After the above modifications, the limits calculations were performed using the same 

delta-log-normal distribution assumptions as used by EPA. L TA and variability factors 

(Vf) were calculated for each plant. After calculating the plant-specific data, the 
combined limits were calculated based on the median of the plant LTAs, and the average 

of the daily maximum and monthly average variability factors. 

Alternative Selenium Limit 

An alternative selenium limit was calculated based only on selenium data from Allen and 

Belews Creek, the same plants used to set EPA's proposed limits. We used data from the 

beginning of 2014 and later. This date range was selected because it better reflects the 

changes in coal and the cycling of coal units on the power grid that has become routine. 

Changes in coal or coal blends and the cycling of units impacts the biological treatment 

system and lengthens the period ofre-adaptation within the treatment system. The 

following procedures were used: 

The self-monitoring data from Allen and Belews Creek dating from the beginning 

of 2014 through early 2015 were used. The exact data appears in the "SE limit after 

20 13" worksheet in this document. 

2 UWAG used the same autocorrelation factor as EPA used for the limits in the 

proposed rule for selenium (p=0.291 ). 

3 For selenium, EPA substituted a constant baseline value of 5 ug/L for every 

detected value that was lower than 5.0. This appeared to be a counterproductive 

replacement of viable detected data with an artificial value. URS also found that 

the use of a 5.0 baseline value, while marginally increasing the L TA, drastically 

lowered the variability factor, producing significantly lower limits for no apparent 

reason. URS therefore used these detected results at face value, without alteration. 

Alternative Mercury Limit 

EPA used only the SER and CWA 308 data for sites Keystone, Hatfield, and Miami Fort. 

This contained only eight data points from each plant. UWAG calculated an alternative 

mercury limit by using all of the data (minus outliers, described below) from three plants: 

Miami Fort, Hatfield, and Pleasant Prairie (PP). Keystone used microfiltration, which is 

a very significant treatment step beyond BAT. EPA did not define microfiltration as a 

part of its model physical/chemical treatment system. Pleasant Prairie has two clarifiers, 

and because of this, EPA stated it was beyond BAT. Having an additional clarifier does 

not necessarily mean that Pleasant Prairie's settling equipment is beyond BAT, as it 

depends on how the clarifiers are designed to operate. Significantly, Pleasant Prairie was 

the only plant sampled that bums PRB coal. Without the inclusion of Pleasant Prairie 

data, the limits calculations would not reflect any PRB-burning facilities. It is believed 

that PRB coal makes treatment of FGD wastewater more difficult, and Pleasant Prairie 

representatives stated that they could not meet the proposed limits, even with the extra 

clarifier. Therefore, Keystone was replaced by Pleasant Prairie in the URS analysis. 

The exact data used are in the "Mercury Limit MF, PP, and Hatfield" sheet in the 

mercury calculation workbook. The original data had three high outliers that failed the 4 

standard deviations test. The following data points were removed. If they were used, the 

calculated limits would be higher than are calculated in this scenario.

Total Mercury Hatfield's Ferry Phys-Chem Treatment Effluent 01/19/10 2030 ng/L 

Total Mercury Pleasant Prairie Phys-Chem Treatment Effluent 05/29/14 1550 ng/L 

The following samples were removed because they had identical mercury results as the 

sample that immediately preceded it in the data set, analyzed on the day before, likely a 

double entry of the same data. In these cases, URS retained the first of the identical 

samples and removed the second. These second samples removed from the calculation 

are listed below.

Total Mercury Miami Fort Phys-Chem Treatment Effluent 03/02/ 11 185.5 ng/1 

Total Mercury Miami Fort Phys-Chem Treatment Effluent 04/05/ 11 175.5 ng/1 

After URS had completed ,its limits calculation, we identified two additional2014 

mercury data points for Pleasant Prairie. Those va'lues are as follows: 

Total Mercur Pleasant Prairie 1/24/14 

Total Mercur Pleasant Prairie 9/9/14 

These values were not used in the limits calculation, but they are unlikely to have any 

significant effect in the limits if recalculated. 

Alternative Arsenic Limit 

URS used arsenic data from Pleasant Prairie rather than the data from Keystone. This 

was because Keystone used microfiltration, which EPA did not define as part of its model 

physical/chemical treatment system. Pleasant Prairie has two clarifiers, and because of 

this, EPA stated it was beyond BAT. The justification for using Pleasant Prairie data 

while eliminating Keystone's data is discussed above in the alternative mercury limit 

section. 

Only the EPA data for arsenic were used for Miami Fort. Self-monitoring data from 

Miami Fort contained mostly ND values with reporting limits ranging from I 0 up to 500 

ug/L. These non-detected values already exceeded the EPA proposed limits, and 

provided no useful information. 

As discussed above, all ND data for arsenic were entered at face value (the value always 

was "<4.0" for the data used).
