RE: STEAM ELECTRIC EFFLUENT LIMITATIONS GUIDELINES (ELG) RULEMAKING

ADDITIONAL INFORMATION TO SUPPORT WE ENERGIES COMMENTS: 

PLEASANT PRAIRIE POWER PLANT FGD WASTEWATER CHARACTERIZATION AND 

TREATMENT PERFORMANCE

 

Dear Mr. Jordan: 

We received your letter dated January 17, 2014, requesting additional information with respect to 

flue gas desulfurization (FGD) wastewater characterization and treatment performance at We 

Energies Pleasant Prairie Power Plant (Pleasant Prairie). As you recall, we submitted substantial 

data and supplemental information for Pleasant Prairie’s FGD chemical precipitation wastewater 

treatment system as part of our comments on the United States Environmental Protection 

Agency’s (EPA) proposed rule to revise technology-based effluent limitations guidelines (ELG) 

and standards for the steam electric power generating point source category (see We Energies 

Comments on EPA Proposed Effluent Limitations Guidelines, September 20, 2013). Pleasant 

Prairie solely burns subbituminous coal, and actual operating data reveal that Pleasant Prairie 

cannot consistently meet the proposed arsenic and mercury limitations associated with EPA’s 

proposed chemical precipitation technology option. This is particularly important because the 

limits derived for arsenic and mercury are carried over and used as the limits for the chemical 

precipitation plus biological treatment technology option. We reiterate that EPA should 

recalculate the proposed limitations including data from a plant solely burning subbituminous 

coal. Below are our responses to your questions. 

1. Please explain why there are no arsenic data for the Pleasant Prairie Power Plant 

for the “Reaction Tank #1 Influent” after November 2009, or for “FGD WWTS 

Effluent – SP 102” for the time period between November 18, 2009 and January 4, 

2013. EPA requests that We Energies provide data associated with these sampling 

locations for the specific time period, if available. 

All available arsenic data for the two specified sampling points representing the influent to 

and effluent from the Pleasant Prairie FGD chemical precipitation wastewater treatment 

system were submitted to the EPA as part of We Energies ELG comments.

Reaction Tank #1 Influent 

Pleasant Prairie’s Wisconsin Pollutant Discharge Elimination System (WPDES) Permit 

(WPDES Permit No. WI-0043583-06-1) does not require arsenic monitoring at the influent 

to the FGD wastewater treatment system. Therefore, all data collected at the Reaction 

Tank #1 Influent for other purposes (e.g., wastewater treatment plant performance test 

results, research projects, etc.), were provided to EPA as part of ELG comments submitted 

by We Energies. No additional data representing the influent to the FGD wastewater 

treatment system have been collected since November 2009. 

FGD WWTS Effluent – SP 102 

The WPDES Permit required a monitoring scan of various parameters to be conducted at 

the effluent from the FGD wastewater treatment system (Sampling Point 102) once the 

FGD system became operational (see WPDES Permit No. WI-0043583-06-1, Permit 

Condition 4.3). The monitoring scan, including an analysis for Total Recoverable Arsenic, 

was conducted on November 13, 2007, and results were submitted to the Wisconsin 

Department of Natural Resources. This data was included as part of the We Energies ELG 

comments submittal. The WPDES Permit does not require any additional arsenic 

monitoring of the effluent from the FGD wastewater treatment system.1

 The rest of the 

data included as part of the We Energies ELG comments submittal was collected for other 

purposes. A split sample was collected on November 18, 2009 during an EPA/UWAG 

sampling event. Additional samples were collected at Sampling Point 102 from January 

2013 – April 2013 to support development of an Application for a Variance of the 

Anticipated Arsenic Limitation at Outfall 001. This data was collected to satisfy the 

variance application requirements specified in s. NR 200.22,Wisconsin Administrative 

Code, Information to be Included in an Application for a Variance. 

“A permittee applying for a variance shall supply the following information... 

Results of monitoring data for the pollutant for which the permittee is seeking a 

variance which represents the past and current levels of effluent quality.” 

s. NR 200.22(1)(e), Wis. Adm. Code (emphasis added) 

Therefore, all data collected at the FGD WWTS Effluent – SP 102 were provided to EPA 

as part of We Energies ELG comments. No additional data representing the effluent from 

the FGD wastewater treatment plant at that sampling point have been collected during these 

“gap” periods or since April 2013. 

2. EPA requests that We Energies provide all available existing data for arsenic and 

mercury representing the influent to and effluent from Pleasant Prairie Power Plant’s 

 

1 Total Recoverable Arsenic is required to be monitored monthly at either Sampling Point 102 (effluent from the 

FGD chemical precipitation wastewater treatment system) or Outfall 001 (combined discharge of all internal 

sampling points and cooling tower blowdown to Lake Michigan). We Energies made the decision to monitor 

arsenic at Outfall 001 and the data have been submitted to the Wisconsin Department of Natural Resources on 

monthly Discharge Monitoring Reports.

chemical precipitation system for FGD wastewater, for the period January 2012 

through December 2013, that have not already been submitted to EPA. Please also 

provide the supplemental information for these data described in Attachment 1. 

As discussed previously, all available existing arsenic data for the specified sampling 

points representing the influent to and effluent from Pleasant Prairie’s FGD wastewater 

treatment system have already been provided to the EPA as part of We Energies ELG 

comments submittal. Additional data representing the arsenic concentration at the 

secondary clarifier effluent are included in Attachment 1. The supplemental information 

for these data is included in Enclosure I. 

Additional mercury data is available characterizing Pleasant Prairie’s FGD wastewater 

treatment system effluent because the WPDES permit requires mercury samples to be 

collected twice a week at Sampling Point 102 to demonstrate compliance with the 1.5 μg/L 

(1500 ng/L) best professional judgment limit. The We Energies ELG comments submittal 

included all available mercury data from November 7, 2007 through July 24, 2013. All 

available mercury data from Sampling Point 102 that were not already submitted to EPA, 

which includes samples from July 31, 2013 – December 18, 2013, are included in 

Attachment 1. Also included in Attachment 1 is additional mercury data for the secondary 

clarifier effluent. The supplemental information for these data is included in Enclosure I. 

No additional mercury data representing the influent to Pleasant Prairie’s FGD wastewater 

treatment system are available for the period January 2012 through December 2013. All 

available existing mercury data at this sampling location have already been provided to the 

EPA as part of We Energies ELG comments submittal. 

3. Please identify the organosulfide additive (e.g., vendor trade name) used in the FGD 

wastewater treatment system corresponding to the data submitted with We Energies’ 

comments and to the data requested above in #1 and #2. 

Since the installation of the Pleasant Prairie wastewater treatment system, three types of 

organosulfide chemical additive have been used: TMT 15 (made by Degussa AG), Nalmet 

1689 (made by Nalco Chemical Company), and Metclear MR2405 (made by GE Betz 

Inc.). The periods corresponding to the various organosulfide chemical additives used at 

the time are described in the table below:

4. Please provide the specifications that are used to determine appropriate coals for 

use at the plant (i.e., specify the factors that limit the use of specific coals at the plant, 

such as chlorine content or sulfur content). 

Pleasant Prairie is designed and permitted to be fueled with subbituminous coal from the 

Powder River Basin in Wyoming and Montana. The coal is purchased using specifications 

which define the allowable ranges for heating value, ash, moisture, and sulfur content. 

Those values are included in the table below: 

Specifications for Pleasant Prairie Subbituminous 

PRB Coal 

Heating Value (BTU/lb) 8,000 – 9,600 

Ash Content (%) 3 – 8 

Moisture Content (%) 20 – 35 

Sulfur Content (%) 0.10 – 0.60 

Additional coal quality information is reviewed when We Energies considers sourcing coal 

from a different mine to evaluate how other constituents will impact plant operations and to 

confirm that permit requirements can be met. Typical coal quality information for the 

mines supplying coal to Pleasant Prairie in 2012 and 2013 are included in Enclosure II. 

5. Please provide the type and source (i.e., mine name and location) of coal used at the 

plant each day from January 2012 through December 2013. In addition, please 

provide the sulfur and chlorine content of the coal used at the plant for each day of 

this period, if available. For days where coal blending occurred, please note the 

percentage of each type of coal used. 

Coal was delivered to Pleasant Prairie from three mines in 2012 and 2013: 

Mine Name Mine Owner Powder River 

Basin Coal Seam 

Location 

Caballo Mine Peabody Energy 

Corporation

Peabody Energy 

Corporation 

Wyodak-Anderson 65 miles south of 

Gillette, Wyoming 

The coal is shipped via rail, and coal samples are collected from each train shipment to 

characterize the heat content, ash, moisture, and sulfur content. 

The plant does not track the percentage of coal used from each mine on a daily basis. Coal 

can be fed directly from the train shipments for immediate use in the boilers, or it can be

unloaded to outdoor storage and reclaimed almost immediately or pushed onto the pile and 

commingled with the existing inventory. Therefore, we cannot provide the exact 

breakdown of chlorine and sulfur content from the coal burned on a daily basis. The sulfur 

content of the coal from each train shipment is provided in Attachment 2. 

Chlorine content is not characterized for each train shipment; however chloride content is 

characterized on a quarterly basis for annual air emission inventory calculations. A sample 

is collected from each train shipment and the samples representing the coal from each mine 

are composited and analyzed for a number of parameters, including chloride. The chloride 

content of the coal from each quarterly sample is provided in Attachment 3. Also included 

are the analyses for other parameters (i.e., arsenic, mercury, selenium, etc.). 

6. Please provide the following information for each day within the range of sampling 

results that have been or are being provided, if available: 

a. Chloride concentration, pH, and average daily oxidation-reduction potential 

(ORP) values within each FGD scrubber system; 

b. Chloride concentration, pH, and average daily ORP values for the influent to 

the FGD wastewater treatment system; and 

c. Electric generation output (MW-hr) for each generating unit serviced by a FGD 

system. 

Please see Attachment 4 for the available information. 

Chloride concentrations, pH values, and oxidation-reduction potential (ORP) values 

were provided for each FGD absorber when data were available. Data were not 

available on certain days for a variety of reasons (i.e., unit offline due to scheduled or 

forced outages, unit offline due to economic reasons, work schedules of chemistry 

technicians, etc.). The chloride concentrations reported on Attachment 4 were the 

results of daily grab sample analyses. Samples were within an acceptable range if the 

chloride concentration was <15,000 mg/L. Only one sample collected during the range 

of sampling results was higher than this maximum allowed value. The pH is monitored 

within each FGD scrubber system via in-line instrumentation and should be within the 

range of 5.5 – 6.0 SU. A grab sample was collected each day and analyzed for pH to 

verify that the instrumentation was providing accurate readings. The results of the 

daily pH grab samples were provided in Attachment 4. There are a few outliers, but 

generally, the pH maintained a steady value between 5.5 and 6.0 SU. Daily ORP 

values were available dating back to March 2013. No samples were collected prior to 

this date. Samples were within an acceptable range if the ORP value was in between 75 

and 350 mV. All results were within the acceptable range. 

Chloride concentration, pH, and average daily ORP values were not available for the 

influent to the FGD wastewater treatment system; however, if these values were 

available, each would likely be very similar to the absorber data.

Enclosure I – Supplemental Information for Additional Analytical Data Submittal for the 

Steam Electric Generating Effluent Guidelines Rulemaking, Pleasant Prairie FGD 

Wastewater Data 

The supplemental information accompanying the Pleasant Prairie FGD wastewater data 

submittal is supplied below. 

Plant Survey ID (from the Questionnaire for the Steam Electric Effluent Guidelines): 6283 

Plant Name: We Energies Pleasant Prairie Power Plant (“Pleasant Prairie”) 

SE Unit IDs associated with each sample (based on responses to the Questionnaire for the 

Steam Electric Effluent Guidelines): SE Unit-1 and SE Unit-2 

FGD System ID associated with each sample (based on responses to the Questionnaire for 

the Steam Electric Effluent Guidelines): FGD-1 and FGD-2 (Note: FGD-1 services SE Unit-1 

and FGD-2 services SE Unit-2) 

Type of fuel(s) burned (e.g., bituminous coal, petroleum coke) in the associated unit(s) 

represented by the samples and the relative contribution of each fuel on the days of 

sampling: Pleasant Prairie is a coal-fired power plant that burns subbituminous (also known as 

Powder River Basin or “PRB”) coal in each of its two generating units. The plant also burns 

bottom and fly ash from older power plants to reclaim some of the carbon in the ash. The old 

ash is burned at approximately one to two percent weight of the total fuel burned. 

As described in our letter, PRB coal from three specific mines (Caballo Mine, Cordero Rojo 

Mine, and North Antelope Rochelle Mine) were delivered and used in 2012 and 2013. The plant 

does not track the percentage of coal used from each mine on a daily basis. 

Electrical generation (MW-hrs) for each generating unit contributing to the FGD 

wastewater flow on the day of sample collection: See Attachment 4 for the gross electrical 

generation output for each generating unit.

is considered confidential business information. 

Other Comments:

All available arsenic and mercury data representing Pleasant Prairie’s FGD wastewater for the 

period January 2012 through December 2013, that have not already been submitted to EPA, are 

provided on Attachment 1. Data is provided, where available, for the following two locations: 

- Internal point within the FGD Wastewater Treatment System (Secondary Clarifier 

Effluent); 

- Effluent from the FGD Wastewater Treatment System (SP 102). 

No data representing the influent to the FGD wastewater treatment system (Reaction Tank #1 

Influent) or Primary Clarifier Effluent are available for the time frame. 

Data is organized alphabetically (by analyte), by sampling location (in chronological order 

through the treatment system), and by sample collection date (in chronological order). One line 

is devoted to each parameter at each sampling location for each day. For instances when 
multiple samples were collected during the day (e.g., results reported for mercury at SP 102 

which include the collection of a sample and field duplicate), the average of the data is provided. 

These instances are called out on the spreadsheet in the “Qualifier Description” column, believed 

to be the logical place to specify comments associated with the data using EPA’s format. For 

calculating the averages, we used the same methodology EPA used, as described on page 10-5 – 

10-6 of the 2013 TDD. All results less than the quantification limit (i.e., the J-values and 

nondetects below the method detection limit) were treated as half of the sample-specific 

quantification limit when calculating the average. 

The data reflect typical operating conditions and are representative of a properly operated 

chemical precipitation treatment system. 

All pollutants were analyzed by the We Energies Laboratory Services (DNR Certification 

Number 241329000). Arsenic was analyzed using Analytical Method EPA 6020A, Inductively 

Coupled Plasma Dynamic Reaction Cell Mass Spectrometry (ICP-DRC-MS), as allowed by 

Chapter NR 219 of the Wisconsin Administrative Code, which specifies the analytical test 

methods and procedures applicable to effluent limitations for discharges from point sources. 

Mercury was analyzed using Analytical Method EPA 245.7, as allowed by the Wisconsin DNR. 

A permit condition in Pleasant Prairie’s Wisconsin Pollutant Discharge Elimination System 

(WPDES) Permit (Permit # WI-0043583-06-1) allows for Analytical Method EPA 245.7 to be 

used for mercury monitoring. 

“1.2.2.1 Mercury Monitoring. NOTE: Because the mercury concentration from the 

FGD treatment system will be at a higher concentration than at Outfall 001, the permittee 

may use a less sensitive analytical method (EPA method 245.7) for mercury analysis at 

Sampling Point 102, in accordance with s. NR 106.145(10)(b), Wis. Adm. Code.” 2006 

PPPP Permit at 3. 

The regulation specified in permit condition 1.2.2.1 is provided below. 

The analytical method used shall be sensitive enough to quantify mercury 

concentrations in the sample or mercury concentrations down to the lowest water quality 

criterion found in ch. NR 105, whichever is greater. s. NR 106.145(10)(b), Wis. Adm. 

Code (emphasis added). 

 

The flow rate at the sampling location at the time of the sample collection is accurately provided 

for Sampling Point 102. This value corresponds to the flow rate reported on the monthly 

Discharge Monitoring Reports. The site does not keep records of the flow rates through the 

internal sampling points, but generally operates the treatment plant at a steady flow rate of 

approximately 40 gpm. This flow rate was translated to 57,600 gpd, assuming 24-hour 
operation, and provided as the “flow rate at the sampling location at the time of sample 

collection” for Secondary Clarifier Effluent. (It should be noted that the treatment plant typically 

does not operate for 24 continuous hours. As denoted on the Questionnaire, the treatment plant 

typically discharges at a rate of 40 gpm, 17 hpd, 199 dpy. Thus, if the flow was normalized to 24 

hours per day and 365 days per year, the normalized flow rate would be 22,244 gpd.)
