### Enclosure 1

Instructions for Sample Collection, Packaging, and Shipment

EPA Sampling Program

The samples you will be collecting are very important. The samples will be used by the U.S. Environmental Protection Agency (EPA) for revising th e effluent limitations guidelines and standards for the Steam Electric Power Gen erating Industry.

These instructions are being provided to We Energies’ Pleasa nt Prairie Power Plant to aid in collecting, packaging, and shipping samples for this sampl ing program.

The plant must collect grab samples for all analytes a t the influent to the FGD wastewater treatment sampling point and 24-hour composite samples for all analytes except mercury and cyanide at the effluent from the FGD wastewater tre atment sampling point. At the FGD wastewater treatment effluent, the plant must co llect cyanide as a single grab sample and mercury must be collected as four individual grab samples over the 24-hour period (i.e., a grab sample collected every six hours).

Samples will be collected once a month for four month s. The samples should be collected and shipped to the laboratories according to the schedule provided in the cover letter of this request. If the plant has any questions re garding the timeline or the steps provided, please contact Mr. Ronald Jordan at (202) 566-1003 or j ordan.ronald@epa.gov.

Equipment Needed

The plant will need to obtain the following equipment to collect, pack, and ship the samples to the laboratories:

• Sample bottles, composite containers, and tubing sets (spe cially-cleaned according to EPA Method 1669);

• Automatic compositor;

• Powder-free gloves;

• Tyvek® coveralls or suitable alternative;

• Dust masks (for use while collecting mercury samples)

• Labels (for sample bottles and shipping samples to labora tories);

• Preservation supplies (see the “Sample Bottles and Pr eservation” Section);

• Coolers;

• Garbage bags;

• Packing material;

• Strapping tape; and

• Traffic Report (will be provided by ERG).

### Sampling Points

The plant must collect samples once per month for four months, based on the schedule specified in the letter. Samples are to be collected fr om each of the two sampling points included in the EPA’s sampling episode. Figure 1 identifies e ach of the sampling points for this sampling program. The following is a description o f the two sampling points:

• 

### FGD wastewater treatment influent (FGD scrubber purge) (SP-1) : This sampling point shall represent the FGD purge stream (e.g., hydroclone overflow) transferred to the FGD wastewater treatment system pri or to any commingling with other wastewaters or treatment system recycle s treams. This sample should be collected from the sample tap located on the seconda ry hydroclone.

• 

### FGD wastewater treatment effluent (SP-2) : This sampling point shall represent the effluent from the FGD wastewater treatment syste m, prior to mixing with dilution water or other streams. This sampling point shou ld be collected from the sample tap that is located on the wastewater piping dow nstream of the effluent storage tanks; where the plant collects its samples a ssociated with its NPDES internal monitoring point.

Analytes

The analytes included in this sampling program include all ana lytes from EPA’s sampling program, except for the dissolved metals analyses (which includes hexavalent chromium). Table 1 contains the listing of all the an alytes included in the monitoring program, as well as the analytical methods that will be used to analyze the samples.

### Sample Bottles and Preservation

Table 2 identifies the sample bottles that are needed fo r collecting samples. The table also identifies the on-site preservation that is requi red for the samples. Please note that the number of sample bottles listed in Table 2 refers t o the number of bottles that will need to be collected from each sampling point for each of the four sets of samples. For the Group II samples, the plant can either preserve the samples with sulfuric acid after sample collection, or the plant can order pre-preserv ed sample bottles.

For the total cyanide samples, the plant should test the wastewater from the sampling points with lead acetate paper (turns black in the presence of sulfide) and potassium iodide starch paper (turns blue/violet in the presence of chl orine). If sulfide is present, the plant will need to dilute the sample with blank water until the sulfide is not detected by the lead acetate paper. If chlorine is present, then t he plant will need to add sodium arsenite until the chlorine is not detected by the potass ium iodide starch paper. After any dilution and/or sodium arsenite is added to the sample, the plant will need to preserve the sample with sodium hydroxide until the sample reaches a pH of 10 S.U. Please see ASTM Method D 7365-09a for more details on the preservation requirements for total cyanide.

NOTE: The number of sample bottles refers to the number of sample bottles needed for each sampling point for each of the four sets of samples.

### Sample Labeling

Label each bottle prior to collecting the sample so i t can be identified by the laboratory. Each self-adhesive label must be completed in indelible ink and must contain the following information:

• Sample number (see Table 3);

• Sampling episode number (see Table 3);

• Sampling point/description (see Table 3);

• Date of sample collection;

• Analysis to be performed;

• Sample bottle type; and

• Required on-site preservation.

If any of the information is incorrect, the plant must revise the label using indelible ink. Once applied to the sample container, the plant must co ver the labels with clear tape to prevent tampering, abrasion, smearing, or loss during trans it. For metal and mercury samples, do not place labels directly on the sample bot tles because of the potential for contamination. Instead, place the label on the outer pl astic bag of the sample bottle. To ensure that the sample label does not become separated from the bottle, the doublebagged sample bottle should be placed in an additional Zi ploc bag after collection.

Table 3 provides the sampling point descriptions, sample numbe rs, and sampling episode number for the plant for this monitoring program. The info rmation in the table should be provided on the sample bottle labels for the appropriate bottles. The “analysis to be performed” should be shown on the label as the followi ng, depending on the specific analysis:

• BOD;

• Group I;

• Group II;

• Total Cyanide;

• Total Metals – 200.8 w/ CC;

• Total Metals – 200.7;

• Total Mercury (for influent and field blank samples);

• Total Mercury – Grab 1 (for FGD wastewater treatment ef fluent laboratory composite samples. The bottles should be l abeled as Grab 1, Grab 2, Grab 3, and Grab 4 for the four respective collec tion times).

The “sample bottle type” should be shown on the label t he same as the “Sample Container and Volume” column in Table 2, except that the quantity should not be included. For example, for total mercury, the “sample bo ttle type” should be “250-mL glass bottle.” The “required on-site preservation” sh ould be shown on the label the same as the “On-Site Preservation” column in Table 2, exce pt that “(acid preserve at laboratory)” does not need to be included for the total me tals and total mercury sample

bottles.

### The laboratory will perform MS/MSD analyses on the total metals and total mercury analyses; however, no additional sample volume is requi red.

Sample Collection

The plant must use clean sampling techniques when collecti ng the total metals and total mercury samples; therefore, the sampling team should fo llow the clean hands/dirty hands sampling techniques outlined in EPA Method 1669. Additionally, t he plant must try to avoid significant contamination during sample collection, especially from sources such as airborne particles, dirt, and corrosion particulates fr om piping, railing, etc.

### The plant must collect grab samples for all analytes a t the influent to the FGD wastewater

treatment system. The plant must collect 24-hour compo site samples for all analytes except cyanide and mercury at the FGD wastewater treatme nt effluent sampling point. The 24-hour composites must be set up to collect equal sam ple aliquots every hour over the 24-hour period. For mercury at the FGD wastewater tr eatment effluent sampling point, the plant must collect four individual grab samples over the 24-hour period (i.e., one mercury grab collected every six hours). For cyanide at th e FGD wastewater treatment effluent sampling point, the plant must collect a singl e grab sample after the one of the mercury grab samples.

If the plant collects the samples from the same taps used for the collection of samples during the EPA sampling episode, the plant can follow the instructions included in the sampling plan drafted for the EPA sampling episode to colle ct the field blank samples, set up the composite containers, and perform the composite pum p-off procedures for the FGD wastewater treatment effluent sampling point. The foll owing instructions can be used to collect the grab samples at the influent to the FGD wa stewater treatment system sampling point and for the mercury and cyanide grab samples at the FGD wastewater treatment effluent sampling point: (NOTE: If a sample tap or valv e is not available to collect these samples or if the FGD wastewater treatment effluent sampling point has intermittent flows which may interfere with the automatic composite colle ction, please contact TJ Finseth, (703) 633-1698 to discuss possible alternatives.)

1. Arrive at the sampling point location and prepare supplies and bottles for the sample collection.

2. Clean hands and dirty hands put on Tyvek® suits, masks, and powder-free gloves.

3. Dirty hands gets a clear plastic bag and opens it slightl y (touching only the outer part of the bag) so that clean hands can place h ands in the bag and open the bag completely.

4. Clean hands then uses the plastic bag to shroud the samp le tap (note that there should be no flow through the sample tap at this t ime). Clean hands will need to puncture a small hole in the bag using the ta p and dirty hands can cable tie the bag to the tap to prevent it from fall ing during sample

collection.

5. Dirty hands opens the outer bags of the field blank wat er and total mercury and total metals field blank sample bottles. Clean hand s opens the inner bag of the field blank water and unscrews the lid. Clean h ands then opens the inner bag of the total mercury and total metals field bl ank sample bottles. Clean hands pours the blank water into the fi eld blank sample bottles under the shrouding, caps the bottles, and closes the inner bags. Clean hands then places the total mercury and total met als bottles in the outer bags and dirty hands closes the outer bag.

6. Dirty hands then opens the valve to the sample tap and pur ges the tap for at least two minutes, then keeps the valve open until all sam ples have been

collected.

### 7. Dirty hands opens the outer bag for the total mercury s ample bottle. Clean hands takes the sample bottle and inner bag and holds the m under the shroud. Clean hands then opens the inner bag, opens the l id of the bottle and fills the total mercury sample bottle. Clean hands caps the sample bottle, closes the inner bag, and places the sample bo ttle in the outer bag. Dirty hands closes the outer bag. The samplers repea t this procedure for the collection of the total metals samples (both EPA 200.8 with collision cell and EPA 200.7), unless the plant is collecting the met als samples as composite samples.

8. The samplers then collect the BOD, Group I, Group II, and total cyanide samples. NOTE: the samplers can collect these samp les using the same technique as the mercury and metals samples, or they can remove the plastic bag shrouding and collect directly from the tap.

9. The Group II and total cyanide samples must be preserved prio r to shipment to the laboratories. Use the information provide d in the “Sample

Bottle and Preservation” section of these instruction f or the preservation steps. Additionally, the BOD, Group I, Group II, and tota l cyanide samples should be placed on ice immediately after sample coll ection/preservation.

Sample Packing and Shipment

The following steps should be used when packing and shipping the s amples to the

laboratories.

1. Make sure that each sample bottle has a label, and tha t the label correctly specifies the sample point.

2. Tighten the lid on each filled sample bottle, being car eful not to overtighten the lid. If bottle threads are dirty to w here the lid is impeded from closing, clean the threads on the bottle being caref ul to not introduce contamination into the sample. Clean the sample bottl e with a cloth rag or paper towel.

3. Prior to packaging, place each sample bottle requiring ≤ 6°C preservation

into an ice chest with wet ice to cool.

4. When each sample requiring ≤ 6°C preservation has reached the desired temperature, wrap each glass sample bottle with two layers of “bubble wrap” (or place bottle in two “bubble bags”). The bubble wr ap must fit snugly and completely cover the sample bottle. Enclose each “bubblewrapped” container and plastic container in an individual sealable plastic freezer bag.

5. Place two garbage bags inside each other in each of the coolers used to ship samples to the laboratories.

6. Place the classicals samples in the garbage bags in th e coolers with proper end up, close the interior garbage bag by tying, or with a tw ist-tie.

7. Add ice to the cooler to keep samples cold during shipment. Ar range blue ice or sealed plastic freezer bags filled with wet ice on top of the sample bottles (if samples require ≤ 6°C preservation). If using wet ice, place the

### ice inside two one-gallon sealable freezer bags. Put at l east 4 × 1⁄2 gallons of ice (4 × 2.5 pounds of ice) in each large cooler and 2 × 1⁄2 gallons of ice (2 × 2.5 pounds of ice) in each small cooler. Use more ice when ambient temperatures are very high. Place the ice inside the sec ond garbage bag.

8. Close the second garbage bag by tying, or with a twist-tie

. 9. Place the metals samples in the garbage bags in a diff erent cooler with proper end up, close the interior garbage bag by tying or wit h a twist-tie. Close the second garbage bag by tying, or with a twist-tie . NOTE: the metals samples are not required to be cooled; however, because the metals and classicals are being analyzed by the same laboratory, the metals can be shipped with the classicals, but the metals samples w ould need to be chilled prior to packing them in the cooler with the clas sicals and ice

would need to be added to the cooler between the interior a nd outer garbage bags to keep the samples cold.

10. Fill in any free space around the bottles in the metals and classicals coolers with additional cushioning material. Sufficient pac king material should be used so that the sample containers will not shi ft during shipment.

11. Fill out and print a traffic report form for the classi cals and metals samples (provided electronically by ERG). Seal the last two pages o f the traffic report form(s) in a plastic envelope secured to the insid e of the top of the cooler(s). NOTE: the top page of the traffic report mus t be sent to ERG at the following address:

Eastern Research Group 14555 Avion Parkway, Suite 200 Chantilly, VA 20151

Attn: TJ Finseth (703) 633-1698

12. Close the cooler(s).

13. Place a completed laboratory address label on the lid o f the cooler(s). The classicals and metals samples should be shipped to TestAme rica as

follows:

TestAmerica

4955 Yarrow Street Arvada, CO 80002 Attn: Elizabeth Eichelberger (303) 736-0100

14. Make several wraps with strapping tape around the cooler pe rpendicular to

the seal to ensure that the lid will remain closed if t he latch is accidentally released or damaged.

15. Place the mercury samples in the garbage bags in a separ ate cooler with proper end up, close the interior garbage bag by tying, or with a twist-tie.

### 16. Do not add ice to the mercury cooler, simply close the second garbage bag by tying, or with a twist-tie.

17. Fill in any free space around the bottles with additional cushioning material. Sufficient packing material should be used so that the sample containers will not shift during shipment.

18. Fill out and print a traffic report form for the mercury samples (provided electronically by ERG). Seal the last two pages of the traffic report form in a plastic envelope secured to the inside of the top o f the cooler. NOTE: the top page of the traffic report must be sent to ERG a t the same address provided in step 11:

19. Close the cooler.

20. Place a completed laboratory address label on the lid o f the cooler. The mercury samples should be shipped to Frontier as follows:

Frontier GeoSciences

414 Pontius Ave. North
Seattle, WA 98109

Attn: Patrick Garcia-Strickland (206) 957-1428

21. Make several wraps with strapping tape around the cooler pe rpendicular to

the seal to ensure that the lid will remain closed if t he latch is accidentally released or damaged.

22. Fill out the necessary paperwork for FedEx or UPS to prepa re the shipment for pick up or drop off. NOTE: the samples must b e shipped priority overnight to arrive at the laboratories the following morning. Ship

the coolers to the laboratories.

23. After the coolers have been dropped off (or picked up), pleas e contact TJ Finseth at (703) 633-1698, to notify him that the samples have b een shipped to the laboratories.

Traffic Reports

An example traffic report will be provided to the plant by ERG for the first sample collection event. The plant will need to make changes t o the traffic report electronically for the other three sample collection events. Some information, such as the date and sample collection times must be entered by the plant after the sample collection and therefore, will not be included in the example provided by ERG.

After the traffic report is completed by the plant, th e plant must print the four pages in the file. The last two pages in the file must be placed in t he cooler for shipment to the laboratories and the first page must be sent to ERG. The plant can keep the second page of the traffic report.

### Engineering Data

The plant must provide engineering data regarding the operatio n of the plant and FGD systems during the sample collection period. Additionall y, the plant must make some field measurements when samples are collected, including pH , temperature, and visual observations, and provide the data to EPA after the sample collection period. The engineering data and field measurement data requirements are in an Excel® spreadsheet titled “Monitoring Program Engineering Data Tables,” which w ill be provided by ERG.

The tables are also included at the end of this enclosure. The plant must complete the engineering data sheets and field measurement sheets in th e Excel® file and e-mail the completed forms to TJ Finseth at thomas.finseth@erg.com

## MEMORANDUM

TO: Ron Jordan, EPA

Jezebele Alicea, EPA

FROM: TJ Finseth, ERG

DATE: 12 November 2010

SUBJECT: Notes from On-Site Review of Industry Self-Monitoring Sampl ing at We

Energies’ Pleasant Prairie Power Plant on November 2-3, 2010

ERG conducted an on-site review of the self-monitoring sampling conducted at the We Energies’ Pleasant Prairie Power Plant (Pleasant Pr airie) located in Pleasant Prairie, WI. ERG was on site for all sample collection activities tha t Pleasant Prairie conducted for the second set of the industry self-monitoring sampling on November 2 and 3, 2010. These notes summarize the sample collection techniques used by Pleasant Prairie at each of the sampling points and EPA’s observations/findings from the on-site review. An overall process water diagram for the Pleasant Prairie plant is provided as Attachment 1. The checklists that EPA completed as part of the on-site review are provided as Attachment 2.

During this set of the industry self-monitoring, Unit 1 wa s shut down to replace a layer of catalyst in its selective catalytic reduction system. The unit was shut down on October 8, 2010, and was expected to commence operation on Friday, November 5, 2010. Therefore, for this set of samples, only Unit 2 was operating.

The following sections describe the sample collection at each of the sampling points and the observations/findings from each sampling point.

FGD Wastewater Treatment Influent (SP-1)

The FGD wastewater treatment influent consists of th e secondary hydrocyclone overflow that is transferred to the equalization tank at the beg inning of the FGD wastewater treatment system; therefore, the samples from this sampling point were collected as grab samples. For this sampling point, Pleasant Prairie used a sample tap off of the drain of the secondary hydrocyclone overflow piping that transfers the secondary hydrocyclon e overflow to the equalization tank. This is the same sampling point that EPA used during its samp le collection.

Sample Collection

To collect the samples of the FGD wastewater treatm ent influent, Pleasant Prairie personnel followed EPA Method 1669 protocols and the EPA-provi ded instructions. Pleasant

### Memorandum

November 9, 2010 Page 2

Prairie personnel shrouded the tap with a clean plastic b ag and let the sample flow from the tap for two minutes prior to collecting any samples. The samp lers then collected the samples underneath the shroud. At this sampling point, Pleasant Pr airie only collected samples for the EPA program and did not collect their own split sample s. All samples were filled from the tap while the samplers held the bottles under the shrouding.

Preservation

Pleasant Prairie personnel followed all method specific ations when preserving the classical samples. The Group II samples were preserve d using H 2 

### SO 4 

### and the pH was confirmed to be below 2 S.U. The cyanide samples were checked for sulfides and chlorine using lead acetate paper and potassium iodide starch paper, respectiv ely. The samplers did not detect sulfides or chlorine in the samples. The cyanide samp les were then preserved using NaOH and the pH was confirmed to be above 10 S.U. The BOD, Group I, Group II, and cyanide samples were all placed on ice after collection or preservati on.

Field Measurements

Pleasant Prairie personnel used a pH probe and a temperatur e probe to measure the pH and temperature of the FGD wastewater influent samples. Pleasant Prairie personnel filled a small bottle with sample after collecting the metals samples and prior to collecting the classicals samples. After completing the classicals sample col lection, Pleasant Prairie personnel transported the field test bottle to the laboratory ar ea, poured some of the sample into a small beaker, and inserted temperature and pH probes into the bea ker with sample. Pleasant Prairie personnel stated that they had already calibrated the te mperature and pH probes; however, ERG did not observe the calibration of the probes. Pleasan t Prairie personnel allowed the temperature and pH stabilize and then recorded the values.

Observations/Findings

ERG observed the Pleasant Prairie personnel collectin g the Set 2 samples of the FGD

wastewater treatment influent stream. Pleasant Prair ie did not collect the field blanks during the sample collection activities because they were colle cted during Set 1. Pleasant Prairie personnel followed all applicable procedures during the sample collect ion. Pleasant Prairie personnel used the correct techniques to preserve the classicals samples . The Group II samples were preserved

18 minutes after collection.

FGD Wastewater Treatment Effluent (SP-2)

The FGD wastewater treatment effluent stream is the effluent from a chemical precipitation system used to treat the Pleasant Prairie FGD wastewater; therefore, the samples for this sampling point were collected as composite samples, except for the mercury and cyanide samples. For the composite samples at this sampling po int, Pleasant Prairie collected the samples using the plant’s existing compliance monitoring poi nt and the existing ISCO auto sampler, which is not the same sampling point that EPA used during its sample collection;

however, the two sampling points are both on the same wa stewater piping and there are no chemical additions or process operations that occur bet ween the two sampling points. The Pleasant Prairie auto sampler is configured with a piece of tubing that connects a tap on the wastewater piping to a three-way control valve. The va lve is controlled by the ISCO auto sampler to either pull sample to the compositor or purge s ample to the drain. When the ISCO sampler is preparing to collect a sample, the valve opens the line to the drain to let fresh sample enter the tubing and once the line is flushed, the valve s witches to allow the sample to be pulled to the compositor. For the mercury and cyanide grab sampl es at this sampling point, Pleasant Prairie collected the samples from one of the efflue nt samples taps, which are the same taps that were used by EPA during its sample collection.

Sample Collection

To collect the samples of the FGD wastewater treatm ent effluent, Pleasant Prairie personnel followed EPA Method 1669 protocols and the EPA-provi ded instructions. To collect the composite samples, Pleasant Prairie personnel repl aced the tubing that connects the threeway control valve to the ISCO auto sampler with specia lly-cleaned silicone tubing. Pleasant Prairie personnel attached one end of the specially-clea ned silicone tubing to the outlet from the three-way control valve and the other end was threaded thr ough the ISCO 6712 auto sampler and attached to a vented cap on a 20-liter carboy. The sampl ers programmed the compositor to collect 830 mL of sample every hour for a 24-hour period. After the 24-hour period, the samplers removed the composite tubing from the ISCO auto s ampler and replaced it with a short piece of Teflon® tubing connected to a length of silicone tubing to transfer the samples to individual sample bottles. The samplers first shook the 20-liter container to homogenize the sample and then they attached a pump-off cap onto the car boy. The Teflon® end of the tubing was then inserted into the carboy and the tubing was purged w ith two liters of sample. Pleasant Prairie personnel then collected the metals samples usi ng a cleanbox. Additionally, the plant collected multi-fill splits in the cleanbox. After a ll the metals samples were collected, the samplers filled the classical samples outside the cl eanbox. Pleasant Prairie collected multi-fill split samples for the Group I and Group II samples; howe ver, for the BOD and cyanide samples, the samplers only collected samples for the EPA progra m.

Pleasant Prairie personnel also collected grab samples for mercury every six hours during the sampling. The samplers collected the mercury sampl es at this sampling point by shrouding one of their effluent sample taps with a clean plasti c bag and letting sample flow through the sample tap for two minutes prior to collecting any sample s. Pleasant Prairie personnel filled the mercury bottles directly from the tap, underneath the s hroud. The samplers collected the mercury samples as multi-fill splits. Pleasant Prai rie personnel also collected the cyanide samples as a grab sample immediately after the first of the four mercury grab samples at the sampling point. Pleasant Prairie personnel did not colle ct a cyanide split sample.

Preservation

Pleasant Prairie personnel followed all method specific ations when preserving the classicals samples, which are the same as those descr ibed in the Preservation section for the FGD

wastewater treatment influent stream. Additionally, t he plant kept the composite container on ice during the sample collection time period.

Field Measurements

Pleasant Prairie personnel did not collect a field tes t sample to test for the temperature and pH. Instead, the samplers calibrated the inline temp erature and pH probes at the effluent sampling location prior to the sampling episode and recorded th e temperature and pH at the time each mercury grab was collected, which was every six hour s. ERG was not present at the time the temperature and pH probes were calibrated.

Observations/Findings

ERG/EPA observed the Pleasant Prairie personnel collec ting the composite set up, composite breakdown, and composite pump off for the Set 2 samples. Pleasant Prairie personnel collected field blank samples for the total metals samples during thi s set. ERG also observed the Grab 1 and 2 mercury grab samples and the cyanide grab sample. Pl easant Prairie personnel collected the mercury field blank sample during the Grab 1 sample. P leasant Prairie personnel followed all applicable procedures during the sample collection and pr eservation, except the samplers did not test the temperature of the composite carboy after the completion of the compositing period. ERG communicated this issue to the samplers to allow the m to fix this for the remaining samples.

ERG noted that the Pleasant Prairie personnel replaced the tubing that connected the three-way control valve to the ISCO auto sampler; howe ver, the Pleasant Prairie personnel did not replace the tubing that connected the wastewater pipi ng to the three-way control valve.
Therefore, ERG cannot be certain that there was not c ontamination from that tubing. ERG communicated this issue to the samplers to allow them t o fix this for the remaining samples.

ERG also noted that the ISCO 6712 auto sampler required t he samplers to thread the tubing (including the end of the tubing) through the pump to set up the composite tubing; however, when the samplers were threading the tubing th rough the ISCO, the end of the tubing was covered with a Ziploc bag to prevent potential conta mination.

NOTE 1: The FGD wastewater secondary clarifier (a lamell a type clarifier) is typically removed from service
every Saturday to clean scale from th e incline section and baffles. Without we ekly cleaning, the secondary clarifier
performance deteriorates to unacceptable levels. Sometimes the system is not re turned to service during a 24-hour
period, so a zero flow for the day will be indicated. Since this is a routine practice, there would be no impact to the
wastewater samples from one we ek compared to another.

NOTE 2: The January flow data had zero flow for a number of consecutive days due to Lake intake warming with
the wastewater discharge line. (Some or all of the cooling tower blowdown and other wastewaters flowing through
the common discharge line can be recirculated to the intake structure in Lake Michigan to keep it free from icing.)
During intake warming, the plant does not discharge FGD wastewater effluent to avoid potential cooling tower
chemistry problems that could arise from mixing the tr eated FGD wastewater with the cooling tower makeup
water from the lake. The plant expects that higher concentra tions of various constituents could be present in samples
taken after this period compared to periods of more continuous effluent discharge.

### SUMMARY

The samples were prepared according to EPA Method 1631E to be analyzed by CVAFS.

### 2

There were no findings from the data review that required a dditional qualifiers in this

dataset.

SAMPLE RECEIPT, HANDLING, AND STORAGE ISSUES

There were no sample receipt issues in this data package.

INITIAL CALIBRATION

FGS performed the initial calibrations on each analysi s day. The initial calibration for the CVAFS analysis consisted of a blank and five calibrat ion standards with a correlation

coefficient ≥ 0.995. All method-specified criteria were met.

INITIAL AND CONTINUING CALIBRATION VERIFICATIONS

All initial and continuing calibration verifications (I CVs, CCVs) met method-specified

criteria.

BLANKS

All the preparation blanks or laboratory reagent blanks (L RBs) and the continuing calibration blanks (CCBs) met method-specified criteria. Some preparation blanks had mercury levels greater than the MDL (0.24 ng/L), but less t han the RL associated with each individual blank (different RLs based on preparation) . Because all of the blank results were less than the RL, no samples were quali fied based on these preparation blank

results.

DUPLICATES

No field duplicate samples were collected with these sa mpling episodes. Two samples were analyzed in duplicate at the laboratory, samples 72095 a nd 72195. The relative percent difference (RPD) for samples 72095 and 72195 were 2.45% an d 3.32%, respectively. The laboratory’s RPD criteria between an alytical duplicates is 24%.

LABORATORY CONTROL SAMPLES

All laboratory control samples were within FGS’s contr ol limits of 80-120% recovery

and 24% RPD.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES

Matrix spikes (MS) and matrix spike duplicates (MSD) we re performed on samples 72095, 72199, and 72195 for the total mercury analyses. All aqueous MS/M SD recoveries were within method specifications of 71-125%. All RPDs met methodspecified criteria.

### 3

DETECTION LIMITS

The laboratory MDL in the synthetic matrix was 0.239 ng/ L. Results below this MDL were reported as not detected (ND).

SUMMARY

The samples were prepared for total metals analysis accor ding to TestAmerica’s “FGD ICP/MS SOP: Inductively Coupled Plasma Mass Spectrometry for Trace Elements Analysis in Flue Gas Desulfurization Wastewaters,” date d October 6, 2010, based on EPA Method 200.8, by ICP/MS analysis.

Any significant findings are summarized below. No addition al data qualifiers were required.

• The matrix spike (MS) and matrix spike duplicate (MSD) rec overies for total silver for samples 72045 and 72095 failed the EPA Method 200.8 contr ol limits of

70–130%.

• The MS/MSD relative percent difference (RPD) for tota l silver for sample 72095

failed the FGD ICP/MS SOP control limits of ±20%.

• The post digestion spike (PDS) recoveries for the follo wing analytes failed TestAmerica’s control limits of 85–115%: arsenic, chromium , selenium, silver,

and vanadium.

INTERNAL STANDARDIZATION

All internal standards used by TestAmerica were within th e method criteria.

INITIAL CALIBRATION

TestAmerica performed the initial calibrations on each analysis day. The initial calibration for the ICP-MS analysis consisted of a bla nk and four calibration standards.

INITIAL AND CONTINUING CALIBRATION VERIFICATION (IC V/CCV)

The initial calibration verifications (ICV) and continu ing calibration verifications (CCV) performed by TestAmerica all had recoveries within the m ethod criteria.

METHOD/INSTRUMENT BLANKS

All the method blanks were less than the reporting limit (RL); however, some elements were above the MDL and flagged with a “J” qualifier. No additional qualifiers were required for method blanks.

All instrument blanks (initial calibration blank (ICB) and continuing calibration blank (CCB)) were less than the RL; however, some element s were above the MDL and flagged with a “J” qualifier. No additional qualifiers were required for instrument blanks.

### 3

REPORTING LIMIT VERIFICATION STANDARD (CRI)

All CRI samples passed TestAmerica’s SOP control limi ts of 50–150% recovery.

LABORATORY CONTROL SAMPLES (LCS)

All LCS samples passed the method QC limits of 85–115% recov ery.

SYNTHETIC FGD INTERFERENCE CHECK SOLUTION

Based on TestAmerica’s SOP, all interference check sa mple A (ICSA) results had analytes of interest with concentrations less than the RL or less than five times the RL when known inherent contaminants are present in the stock solution used to make the

ICS.

All interference check sample B (ICSAB) synthetic sp ikes recovered within

TestAmerica’s SOP criteria of 70–130% of the true value.

SERIAL DILUTION

The serial dilution performed on sample 72095 passed TestAmer ica’s criteria of ±10%

difference.

FIELD DUPLICATES

No field duplicate samples were collected with these sa mpling episodes.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES

MS and MSD were performed on samples 72045 and 72095. The total se lenium results in the MS and MSD samples for sample 72045 and the MS sample for sample 72095 failed the 70-130% recovery method control limits and were flagged w ith a “4” qualifier indicating concentrations in the parent samples were grea ter than four times the spike amounts. These data were considered acceptable based on th e LCS passing the method

control limits.

The total silver results in the MS and MSD samples for b oth samples 72045 and 72095

failed the 70-130% method control limits with low recoveri es and were flagged with an “F” qualifier. Additionally, the RPD for silver betwee n the MS and MSD for sample 72095 failed the ICP/MS SOP ±20% control limits. The poor r ecoveries and RPD of silver are probably due to high sulfates in this episode’s samples capable of forming

insoluble silver sulfide and/or silver sulfate.

### 4

Otherwise, all MS/MSD spike recoveries were within th e method control limits of 70-

130% and the RPD for the MS/MSDs were within the FGD ICP /MS SOP control limits of ±20 percent. No additional data qualifiers were required.

POST DIGESTION SPIKES

The PDS performed on sample 72095 passed TestAmerica’s cont rol limits of 85–115% recovery for all analytes, except for arsenic, chromium , selenium, silver, and vanadium, which were all flagged with a “W” qualifier. No additional data qualifiers were required for PDS samples.

DETECTION LIMITS

The laboratory performed an MDL study in the synthetic F GD wastewater matrix, instead of reagent water.

SUMMARY

The samples were prepared for total metals analysis acc ording to TestAmerica’s SOP for ICP Analysis for Trace Metals by Method 200.7. Any signific ant findings are summarized below. No additional data qualifiers were requir ed.

• The matrix spike (MS) and matrix spike duplicate (MSD) rec overies for total barium for sample 72095 failed the EPA Method 200.7 control li mits of 70–

130%.

• The MS/MSD relative percent difference (RPD) for total magnesium for sample

72095 failed TestAmerica’s SOP control limits of ±20%.

• The post digestion spike (PDS) for titanium for sample 72095 failed TestAmerica’s control limits of 85–115% recovery.

SAMPLE RECEIPT, HANDLING AND STORAGE ISSUES

There were no sample receipt issues in this data package.

INTERNAL STANDARDIZATION

While the internal standard (ISTD) yttrium was used for these analyses, no checks for the

ISTD recoveries within the ±30% criterion of the calibra tion blank as per Section 9.11 of

the SOP were seen. All ISTD were within the control limits.

INITIAL CALIBRATION

TestAmerica performed the initial calibrations on each analysis day. The initial calibration for the ICP analysis consisted of a blank an d one calibration standard.

INITIAL AND CONTINUING CALIBRATION VERIFICATIONS

The initial calibration verifications (ICV) and continu ing calibration verifications (CCV) performed by TestAmerica all had recoveries within the m ethod criteria.

METHOD/INSTRUMENT BLANKS

All the method blanks were less than the reporting limit (RL); however, some elements were above the method detection limit (MDL) and were f lagged with the “J” qualifier.

All instrument blanks (initial calibration blank (ICB) and continuing calibration blank (CCB)) were less than the RL; however, some element s were above the MDL and were flagged with the “J” qualifier.

### 3

REPORTING LIMIT VERIFICATION STANDARD (CRI)

All CRI samples passed TestAmerica’s SOP control limi ts of 50–150% recovery.

LABORATORY CONTROL SAMPLES (LCS)

All LCSs passed the method control limits of 85–115% recover y.

INTERFERENCE CHECK SOLUTIONS

Interference checks were performed using the synthetic ma trix as the check solution. All data quality objectives met TestAmerica’s SOP criteria.

SERIAL DILUTION (SRD)

Serial dilutions were performed for each batch of total samples. All serial dilution percent differences were less than 10% as required by TestAmerica ’s SOP.

FIELD DUPLICATES

No field duplicate samples were collected with these sa mpling episodes.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES (MS/MSD)

MS and MSDs were performed on the total samples of 72095 and 72045. Some elements with high concentrations failed the EPA 200.7 Method spike recovery control limits of 70–130% but were flagged with a “4” qualifier indicating that the c oncentration in the parent sample was greater than 4 times the spike and co uld not be reliably calculated. These data were considered acceptable based on the LCS pas sing the method control limits. Otherwise, all MS/MSD spike recoveries were within the method control criteria of 70-130%, except for barium for sample 72095, which had a reco very of 65% and was qualified with an “F”. The RPD for all MS/MSDs were wi thin TestAmerica’s ± 20% requirement, except for magnesium for sample 72095. No add itional data qualifiers were

needed.

POST DIGESTION SPIKE (PDS)

The PDS performed on sample 72095 passed TestAmerica’s cont rol limits of 85–115% recovery for all analytes except titanium, which was qual ified with a “W”. No additional data qualifiers were required.

SUMMARY

All samples were analyzed within the holding time specif ied in 40 CFR 136 Table II. All samples were preserved appropriately unless otherwise speci fied below.

Field duplicate samples were not collected for these ep isodes. Depending on the method, a laboratory duplicate was analyzed, instead. The Relati ve Percent Difference (RPD) between the sample and its duplicate was less than 20% unl ess otherwise noted below.

If applicable, the appropriate number of standards was used to create a calibration curve. If sample results were above the highest standard used t o create the curve, the sample was diluted and reanalyzed. All sample results were between the lowest and highest standards unless noted below. Additionally, unless otherwise noted, a ll calibration blanks and calibration verification samples met the criteria sp ecified in the method.

If required by the method, the quality control sample (QC S), a secondary source standard used to verify calibration, was always within the cont rol limits specified by the method.

As described below, the analyte of interest was detecte d above the method detection limit (MDL) in some laboratory reagent blanks (LRB). However , the analyte of interest was never detected above the reporting limit (RL) in the LRBs . If required by the method, all laboratory fortified blanks (LFB) met the criteria spec ified in the method unless specified

below.

If required by the method, a matrix spike (MS) sample wa s analyzed on sample 72045 for each analyte to check for matrix interferences. For so me analytes, TestAmerica spiked more samples than required. All MS samples analyzed met the criteria specified in the

method unless described below.

DATA NOTES/ISSUES

Ammonia

No issues were identified by the data reviewer.

BOD 5



### TestAmerica analyzed five dilutions, but no dilutions had a dissolved oxygen (DO) depletion greater than 2.0 mg/L for sample 72041 and 72091. Theref ore, BOD 5 

### was reported as not detected for these samples. The rest of the samples had at least one dilution with a DO depletion greater than 2.0 mg/L. As requ ired in the method, the final result was calculated by taking the average of the resul ts for all dilutions with a DO depletion greater than 2.0 mg/L and a final DO greater than 1.0 mg/L.

BOD was not detected above the RL in any method blanks. Ho wever, for one batch, the results for the three water/unseeded blanks were 0.22 mg/L , 0.14 mg/L, and 0.16 mg/L.

### 3

One of these water blanks was above the method contro l criteria of 0.20 mg/L. However, all samples contained in this batch (samples 72041 and 72045) we re either qualified with a “J” meaning that the sample result was an estimated v alue because it was below the RL or BOD was not detected in the sample, so no further qual ification was necessary.

One of the three batches had a seed correction factor lower than 0.6 mg/L. The seed correction factors were 0.6267 mg/L, 0.5776 mg/L, and 0.6384 mg/L for b atches 33523, 33769, and 33938, respectively. Unlike previous episodes, TestAmeric a did not flag samples in batch 33769 with an “s” indicating the seed corre ction blank (SCB) recovery was low. This low seed correction factor suggests that s amples 72191, 72195, and 72199 may be biased low. Therefore, these samples were also flagged with an “s”. Sample 72191 was already flagged by TestAmerica with a “J” meaning tha t the sample result was
an estimated value because it was below the RL, so no fur ther qualification was necessary. However, samples 72195 and 72199 were flagged as minim um values. Due to the short holding time for the analysis, the samples could not be reanalyzed.

All glucose-glutamic acid standards and laboratory duplicat es were analyzed appropriately and met the criteria specified in SM 5210B.

Chloride and Sulfate

The MS and matrix spike duplicate (MSD) results for sam ple 72045 for sulfate and

chloride were above the calibration curve. TestAmerica did not reanalyze the samples with a higher dilution factor because the percent recov eries were within EPA method 300.0 control limits. If reported, these MS/MSD results w ill be qualified as estimated values. The LFB associated with this sample met the me thod criteria. The analyzed result for sample 72045 was within the calibration curve, so there was no need to qualify this sample.

COD

The percent recovery for the MSD analyses for sample 72045 was below the control limits of 90-110% required by EPA method 410.4. The percent recov eries for the MS and MSD analyses for this sample were 109% and 87%, respective ly. Because the MS percent recovery met the method criteria and an MSD is not required by the method, sample 72045 was not qualified. The LFB percent recoveries a ssociated with sample

72045 met the method criteria.

Cyanide

Samples 72041 and 72045 were received by the laboratory at neutra l pH. The lab added more NaOH to increase the pH to greater than 10 S.U. These samples are qualified as

estimated values.

Results for the following samples were less than the l owest calibration standard (0.01 mg/L): 72095, 72195, and 72199. Because all of these samples were a lready flagged by

### 4

TestAmerica with a “J”, meaning the sample result was an estimated value because it was below the RL, no further qualification was necessary.

The percent recoveries for the MS and MSD analyses o f sample 72045 were both 85%, which is outside of the laboratory control criteria of 90-110%. However, because there are no criteria for MS/MSD analyses specified in SM 4500 CN - 

### E, no further qualification was necessary.

Nitrate/Nitrite

No issues were identified by the data reviewer.

Phosphorus

The percent recoveries for the MS/MSD analysis of sam ple 72045 were not within the control limits of 90-110% specified in EPA Method 365.1 or within the laboratory control limits of 71-128%. The percent recoveries of the MS and MSD samples were 19% and 21%, respectively. The result for sample 72045 was only slightly above the RL. This low sample result could have caused the low percen t recovery. Nevertheless, sample 72045 was qualified as a minimum value. The LFB percent recov ery met the method

criteria.

TDS

Constant weight was not achieved after 3 drying cycles fo r all samples. It should be noted that the weight increased from the first weighing to the second weighing for all samples. Method 2540C warns that samples which contain high levels o f calcium, magnesium, chloride, and sulfate may be hygroscopic meaning they abso rb moisture from the air. FGD wastewater contains high concentrations of all o f these species. This was likely the cause for the inconsistent weight calculations. The sam ples were not qualified, but results may be biased high.

The RPDs for laboratory duplicates from samples 72045 and 72191 w ere less than 10% as required by SM 2540C. However, the RPD for sample 72091 was 14%. Because the RPD was greater than the method control limits, sampl e 72091 was qualified as an

estimated value.

TDS was detected at 6.0 mg/L in the method blank associa ted with samples 72191, 72195, and 72199. The method blank result was greater than the MDL (4.7 mg/L), but less than the RL (10 mg/L). No qualification was necessar y because the blank result was

less than the RL.

TKN

The percent recovery for the LFB associated with sampl es 72041, 72045, 72091, 72095, 72191, 72195, and 72199 was not within the method control limits of 90-11 0%, but was

### 5

within the laboratory control limits of 77-115%. The percen t recoveries for the LFB and LFBD were 84% and 86%, respectively. Because the percent r ecovery of the LFB was below the method criteria, samples 72041, 72045, 72091, 72095, 72191, 72195, and 72199 were qualified as minimum values.

TestAmerica performed MS/MSD analysis on sample 72045. The percent recoveries for the MS and MSD samples were 77% and 93%, respectively. The MS sample did not meet the method control limits of 90-110%, but did meet the labo ratory control limits of 54-

131%. The LFB associated with this batch was also not wit hin the laboratory control limits, so this may have caused the low MS percent reco very. Also, the sample concentration was greater than 4 times the spike amoun t in the MS and MSD samples, so TestAmerica stated that the percent recoveries and RP Ds could not be reliably calculated. Therefore, sample 72045 was not additionally qualified based on the MS failure because it is not possible to determine if the MS failure was a result of matrix interferences or the low spiking level.

TKN was detected at 0.133 mg/L in the LRB associated with samples 72041, 72045, 72091, 72095, 72191, 72195, and 72199. The blank result was greater than the MD L (0.077 mg/L), but less than the RL (1.0 mg/L). Because the bla nk result was less than the RL, no samples were qualified based on the LRB result.

TSS

The RPD for the laboratory duplicate of sample 72045 was 13%. This RPD was greater than the method control criteria of 10%. Sample 72045 and its duplicate were already qualified by TestAmerica with a “J” meaning that the resul t is an estimated value because the result is below the RL, so no further qualificatio n was necessary.

SUMMARY

The samples were prepared according to EPA Method 1631E to be analyzed by CVAFS.

There were no findings from the data review that required a dditional qualifiers in this dataset. The following summarizes the findings from the data review:

SAMPLE RECEIPT, HANDLING, AND STORAGE ISSUES

There were no sample receipt issues in this data package.

INITIAL CALIBRATION

FGS performed the initial calibrations on each analysi s day. The initial calibration for the CVAFS analysis consisted of a blank and five calibrat ion standards with a correlation

coefficient ≥ 0.995. All method-specified criteria were met.

INITIAL AND CONTINUING CALIBRATION VERIFICATIONS

All initial and continuing calibration verifications (I CVs, CCVs) met method-specified

criteria.

BLANKS

All the preparation blanks or laboratory reagent blanks (L RBs) and the continuing calibration blanks (CCBs) met the method-specified crite ria. Because all of the blank results were less than the RL, no samples were quali fied based on these preparation blank

results.

DUPLICATES

No field duplicate samples were collected with these sa mpling episodes. Two samples were analyzed in duplicate at the laboratory, samples 72046 a nd 72246. The relative percent difference (RPD) for samples 72046 and 72246 were 4.25% an d 0.84%, respectively. The laboratory’s RPD criteria between an alytical duplicates is 24%.

LABORATORY CONTROL SAMPLES

All laboratory control samples were within FGS’s contr ol limits of 80-120% recovery

and 24% RPD.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES

Matrix spikes (MS) and matrix spike duplicates (MSD) we re performed on samples 71996, 72046, 72150, and 72246. All aqueous MS/MSD recoveries were within th e

### 3

method specifications of 71-125%, except for the MS samples for 72046 and 72150, which had recoveries of 20.1% and 54.5%, respectively. All RPD s met method-specified criteria of less than or equal to 24%, except for samples 72046 and 72150, which had RPDs of 72.2% and 24.5%, respectively. Because the MSDs an d the associated LCSs were within the method specifications, no data qualificati on is required for these samples.

DETECTION LIMITS

The laboratory MDL in the synthetic matrix was 0.239 ng/ L. Results below this MDL were reported as not detected (ND).

### SUMMARY

The samples were prepared for total metals analysis according to TestAmerica’s “FGD ICP/MS SOP: Inductively Coupled Plasma Mass Spectrometry for Trace Elements Analysis in Flue Gas Desulfurization Wastewaters,” dated October 6, 2010, based on EPA Method 200.8, by ICP/MS analysis.

Any significant findings are summarized below. No additional data qualifiers were required.

• The serial dilution for selenium for sample 72096 failed TestAmerica’s criteria of

±10% difference.

• The matrix spike (MS) and matrix spike duplicate (MSD) recoveries for silver for sample 72096 failed the EPA Method 200.8 control limits of 70–130%.

• The MS and MSD recoveries for selenium and silver for sample 72246 failed the

EPA Method 200.8 control limits of 70–130%.

• The MS/MSD relative percent difference (RPD) for silver for sample 72246 failed

the FGD ICP/MS SOP control limits of ±20%.

• The post digestion spike (PDS) recoveries for silver failed TestAmerica’s control

limits of 85–115%.

INTERNAL STANDARDIZATION

All internal standards used by TestAmerica were within the method criteria.

INITIAL CALIBRATION

### 3

TestAmerica performed the initial calibrations on each analysis day. The initial calibration for the ICP-MS analysis consisted of a blank and four calibration standards.

INITIAL AND CONTINUING CALIBRATION VERIFICATION (ICV/CCV)

The initial calibration verifications (ICV) and continuing calibration verifications (CCV) performed by TestAmerica all had recoveries within the method criteria.

METHOD/INSTRUMENT BLANKS

All the method blanks were less than the reporting limit (RL); however, some elements were above the MDL and flagged with a “J” qualifier. No additional qualifiers were required for method blanks.

All instrument blanks (initial calibration blank (ICB) and continuing calibration blank (CCB)) were less than the RL; however, some elements were above the MDL and flagged with a “J” qualifier. No additional qualifiers were required for instrument blanks.

REPORTING LIMIT VERIFICATION STANDARD (CRI)

All CRI samples passed TestAmerica’s SOP control limits of 50–150% recovery.

LABORATORY CONTROL SAMPLES (LCS)

All LCS samples passed the method QC limits of 85–115% recovery.

SYNTHETIC FGD INTERFERENCE CHECK SOLUTION

Based on TestAmerica’s SOP, all interference check sample A (ICSA) results had analytes of interest with concentrations less than the RL or less than five times the RL when known inherent contaminants are present in the stock solution used to make the

ICS.

All interference check sample B (ICSAB) synthetic spikes recovered within

TestAmerica’s SOP criteria of 70–130% of the true value.

The ICSA solution for the method 200.8 analysis exceeded the acceptance limits for Chromium in analytical batch 280-40682. The lab has confirmed with the vendor that Chromium is a trace impurity in the ICSA solution. Therefore, corrective action was deemed unnecessary; the associated data have been flagged “^”.

### 4

SERIAL DILUTION

The serial dilution performed on sample 72096 passed TestAmerica’s criteria of ±10% difference for all analytes except selenium, which was flagged “V.” No further data qualifiers were needed for the serial dilution.

FIELD DUPLICATES

No field duplicate samples were collected with these sampling episodes.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES (MS/MSD)

MS and MSD were performed on samples 72096 and 72246. The MS/MSD for sample 72096 failed the method control limits of 70–130% recovery for selenium and silver. Selenium was flagged for the MS/MSD with a “4” qualifier indicating that the concentration in the parent sample was greater than 4 times the spike and could not be reliably calculated. This result was considered acceptable based on the LCS passing the method control limits. Silver was flagged for the MS/MSD with an “F” qualifier and it is likely that silver failed due to matrix interference from the high concentration of sulfates,

which can form insoluble silver sulfide and/or silver sulfate. The silver recoveries in the associated LCS/LCSD were acceptable.

The MS/MSD for sample 72246 failed the method control limits of 70–130% recovery for selenium and silver, which were flagged with an “F” qualifier. The RPD failed the FGD ICP/MS SOP control limits of ±20% for silver for sample 72246. No additional data qualifiers were required for MS/MSD samples.

Otherwise, all MS/MSD spike recoveries were within the method control limits of 70-

130% and the RPD for the MS/MSDs were within the FGD ICP/MS SOP control limits of ±20 percent. No additional data qualifiers were required.

POST DIGESTION SPIKES (PDS)

The PDS performed on sample 72096 passed TestAmerica’s control limits of 85–115% recovery for all analytes, except for silver, which was flagged with a “W” qualifier. It is likely that silver failed due to matrix interference from the high concentration of sulfates,

which can form insoluble silver sulfide and/or silver sulfate. The silver recoveries in the associated LCS/LCSD were acceptable. No additional data qualifiers were required.

DETECTION LIMITS

The laboratory performed an MDL study in the synthetic FGD wastewater matrix, instead of reagent water.

### SUMMARY

The samples were prepared for total metals analysis acc ording to TestAmerica’s SOP for ICP Analysis for Trace Metals by Method 200.7. Any signific ant findings are summarized below. No additional data qualifiers were requir ed for this data set.

• Aluminum, calcium, iron, magnesium, and manganese wer e measured above the reporting limit (RL) in a method blank; however, the conc entration of these elements in the samples associated with this method blank were at least 10 times

the blank result or below the RL.

• The matrix spike (MS)/matrix spike duplicate (MSD) rel ative percent difference (RPD) for boron, calcium, and magnesium for sample 72096 failed TestAmerica’s ± 20% requirement.

• The post digestion spike (PDS) for calcium, manganese, t itanium, and zinc for sample 72096 failed TestAmerica’s control limits of 85-115% re covery.

SAMPLE RECEIPT, HANDLING AND STORAGE ISSUES

There were no sample receipt issues in this data package.

INTERNAL STANDARDIZATION

While the internal standard (ISTD) yttrium was used for these analyses, no checks for the

ISTD recoveries within the ±30% criterion of the calibra tion blank as per Section 9.11 of

the SOP were seen. All ISTD were within TestAmerica’ s SOP control limits.

INITIAL CALIBRATION

TestAmerica performed the initial calibrations on each analysis day. The initial calibration for the ICP analysis consisted of a blank an d one calibration standard.

INITIAL AND CONTINUING CALIBRATION VERIFICATIONS

The initial calibration verifications (ICV) and continu ing calibration verifications (CCV) performed by TestAmerica all had recoveries within the m ethod criteria.

### 3

METHOD/INSTRUMENT BLANKS

All the method blanks were less than the RL, except for MB 280-40683/1-A. Aluminum, calcium, iron, magnesium, and manganese were measured ab ove the RL in this method
blank; however, the concentration of these elements in the samples associated with this

method blank were at least 10 times the blank result or b elow the RL. Therefore, no data needed qualification regarding the method blank result. In the other method blanks, some elements were above the method detection limit (MDL), but less than the RL; therefore, these blanks and were flagged with the “J” qualifier.

All instrument blanks (initial calibration blank (ICB) and continuing calibration blank (CCB)) were less than the RL; however, some element s were above the MDL and were flagged with the “J” qualifier.

REPORTING LIMIT VERIFICATION STANDARD (CRI)

All CRI samples passed TestAmerica’s SOP control limi ts of 50–150% recovery.

LABORATORY CONTROL SAMPLES (LCS)

All LCSs passed the method control limits of 85–115% recover y.

INTERFERENCE CHECK SOLUTIONS

Interference checks were performed using the synthetic m atrix as the check solution. All data quality objectives met TestAmerica’s SOP criteria.

SERIAL DILUTION (SRD)

All serial dilution percent differences were less tha n 10% as required by TestAmerica’s

SOP.

FIELD DUPLICATES

No field duplicate samples were collected with these sa mpling episodes.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES (MS/MSD)

Matrix spikes (MS) and matrix spike duplicates (MSD) w ere performed on the total samples of 72096 and 72246. Some elements with high concentrat ions failed the EPA 200.7 Method spike recovery control limits of 70–130% but were f lagged with a “4” qualifier indicating that the concentration in the paren t sample was greater than 4 times the spike and could not be reliably calculated. These da ta were considered acceptable based on the LCS passing the method criteria. Otherwi se, all MS/MSD spike recoveries

were within the method control criteria of 70-130%. The RPD for all MS/MSDs were

### 4

within TestAmerica’s ± 20% requirement, except for boron, calcium, and magnesium for sample 72096. These elements were flagged with an “F” qualif ier.

POST DIGESTION SPIKE (PDS)

The PDS performed on sample 72096 passed TestAmerica’s contr ol limits of 85-115% recovery for all analytes except boron, calcium, man ganese, sodium, titanium, and zinc. Calcium, manganese, titanium, and zinc were qualified wit h a “W;” however, Because the spike level in the MS/MSD analyses for these ele ments was less than 4 times the sample concentration, there is no evidence of matrix in terferences. Additionally, these elements passed TestAmerica’s requirement of percent d ifferences less than 10% for the serial dilution for sample 72096. Boron and sodium failed t he PDS; however, the percent recoveries were not calculated by the laboratory becaus e their concentrations were greater than 4 times the PDS spike level. Boron and sodiu m also passed the serial dilution for sample 72096 demonstrating no significant matrix interfe rences.

DETECTION LIMITS

The laboratory performed an MDL study in the synthetic F GD wastewater matrix, instead of reagent water.

SUMMARY

All samples were analyzed within the holding time specif ied in 40 CFR 136 Table II. All samples were preserved appropriately unless otherwise speci fied below.

Field duplicate samples were not collected for these ep isodes. Depending on the method, a laboratory duplicate was analyzed, instead. The Relati ve Percent Difference (RPD) between the sample and its duplicate was less than 20% unl ess otherwise noted below.

If applicable, the appropriate number of standards was used to create a calibration curve. If sample results were above the highest standard used t o create the curve, the sample was diluted and reanalyzed unless otherwise specified below. Al l sample results were between the lowest and highest standards unless noted below. Additi onally, unless otherwise noted, all calibration blanks and calibration verificat ion samples met the criteria specified

in the method.

If required by the method, the quality control sample (QC S), a secondary source standard used to verify calibration, was always within the cont rol limits specified by the method

unless otherwise noted below.

As described below, the analyte of interest was detecte d above the method detection limit (MDL) in some laboratory reagent blanks (LRB). However , the analyte of interest was never detected above the reporting limit (RL) in the LRBs . If required by the method, all laboratory fortified blanks (LFB) met the criteria spec ified in the method unless specified

below.

If required by the method, a matrix spike (MS) sample wa s analyzed on samples 72042, 72096, and/or 72246 for each analyte to check for matrix interf erences. For some analytes, TestAmerica spiked more samples than require d. MS samples analyzed met the criteria specified in the method unless described below.

DATA NOTES/ISSUES

Ammonia

The MS result failed criteria at 111% recovery and was qualified with an “F” flag. The MSD and LCS recoveries demonstrate that the analysis was under control. No additional qualifiers were required.

BOD 5



### TestAmerica analyzed five dilutions, but no dilutions had a dissolved oxygen (DO) depletion greater than 2.0 mg/L for samples 72092, 72146, 72150 72042, 72046, 71992, 71996, and 72246. Therefore, BOD 5 

### was reported as not detected for these samples. The rest of the samples had at least one dilution with a DO depletion greater than 2.0 mg/L. As required in the method, the final result was calculat ed by taking the average of the results for all dilutions with a DO depletion greater t han 2.0 mg/L and a final DO greater than 1.0 mg/L.

One of the three batches had a seed correction factor lower than 0.6 mg/L. The seed correction factors were 0.632 mg/L, 0.5533 mg/L, and 0.6267 mg/L for batches 38776, 39101, and 39326 respectively. The samples in batch 39101 should be flagg ed with an “s” indicating the seed correction blank (SCB) recovery was low. This low seed correction factor suggests that samples 72042, 72046, and 71992 may be biased low; however all these samples had a result of ND and ther efore do not require qualification.

All glucose-glutamic acid standards and laboratory duplicat es were analyzed appropriately and met the criteria specified in SM 5210B.

Chloride and Sulfate

The MS/MSD results of samples 72246 for sulfate and chlori de were above the calibration curve. TestAmerica did not reanalyze the s amples with a higher dilution factor because the percent recoveries were within EPA method 300. 0 control limits. If reported, these MS/MSD results will be qualified as estimated val ues. The LFB associated with this sample met the method criteria. The analyzed resu lt for sample 72246 was within the calibration curve, so there was no need to qualify this s ample.

COD

Several LRB and Calibration Blanks (CB) had results gr eater than the MDL; however, all the LRB and CB results less than the RL and were flagge d with a “J” qualifier. No further qualifications are necessary.

One LFB, LCSD from batch 41304, had a percent recovery grea ter that the 90-110% criteria. The LFB was flagged with a “*” qualifier indic ating the LCS or LCSD exceeds

### 4

the control limits. The sample 72046, which is associated with this LFB, was also flagged with “*” qualifier.

The percent recovery for the MS/MSD analyses for sam ples 72096 and 72246 were above the control limits of 90-110% required by EPA method 410.4. The percent recoveries for the MS and MSD analyses for sample 72096 were 115% and 118%, respectively and the recoveries for sample 72246 were 131% and 132%, respectively. These results were flagged with an “F” qualifier because t hey exceed control limits. The LFB percent recoveries associated with samples 72096 and 72246 m et the method

criteria.

MS/MSDs were not performed in batches 41739 and 41304. The sampl es associated with these batches include 72042 and 72046. These sample results were qualified with an “F” qualifier because there were no MS/MSD results.

Cyanide

The calibration was performed using standards ranging from 0.00 ppb to 400.0 ppb. The method states that the appropriate calibration range of s tandard concentrations for this method are between 5 ppb and 20 ppb. Samples 72142, 72092, 72096, 72046, 72242, a ll

had results ≥ 20 ug/L; but were not diluted because they were within the ca libration range performed by the laboratory.

The MS/MSD results for sample 72246 passed the recovery cr iteria; however, the MS/MSD results for sample 72096 failed recovery criteria. The MS/MSD results for 72096 were qualified with an “F” flag. The associated LCS/LC SD recoveries were

within control limits.

Nitrate/Nitrite

The RPD between the LFB and a duplicate LFB from batch 280-40320 is 10.7%. This does not meet the control limits, and therefore the LF B, LFB duplicate, and associated samples are flagged with a “*” qualifier meaning RPD of the LCS and LCSD exceeds the

control limit. The RPD for the MS/MSD in this batch was 1 percent; therefore the system appears to be in control. No further qualifiers were nee ded.

The MS/MSD results for samples 72042, 72096, and 72246 were above t he calibration curve. TestAmerica did not reanalyze these MS/MSDs with a higher dilution factor, but the MS/MSD results for samples 72246 and 72042 were flagged with an “E” qualifier because the results exceeded calibration range. The MS/MSD results for sample 72096 were not flagged with “E” qualifier because the percent re coveries for the MS/MSD analysis of sample 72096 were not within the method control limits of 90-110 percent; therefore, these MS/MSD results were flagged with an “ F” qualifier. The percent recoveries for the MS/MSD of 72096 were 118% and 121%, respectiv ely. Additionally, the MS of sample 72042, and the MSD of sample 72246 were not wi thin the method control limits of 90-110%. The percent recovery of the MS D for sample 72246 was 89%

### 5

and the percent recovery of the MS of sample 72042 was 88 pe rcent; however neither MS/MSDs were flagged with an “F’ qualifier because they d id meet the laboratory control limits. If reported, the 72042 MS should be flagged w ith an “F” qualifier, the 72096 MS/MSD should be qualified as estimated, and the 72246 MS sho uld be flagged with an “F” qualifier.

Phosphorus

The LRB was greater than the MDL at 0.0141 mg/L, however th e result was less than the RL. The LRB results were flagged with a “J” qualifier b ecause the result was less than the RL but greater than the MDL. No further qualifiers are needed. All samples that contained the analyte were also flagged with a “B” qualif ier because the compound was found in the blank and the sample. All calibration blank r esults were also above the MDL but less than the RL, and therefore are also flagged wi th a “J” qualifier.

The percent recoveries for the MS/MSD analysis of sa mples 72096 and 72246 were not within the control limits of 90-110% specified in EPA Method 365. 1. However the MS/MSD of sample 72096 were within the laboratory control limits of 71-128%. The percent recoveries of the MS and MSD for sample 72096 were 87% and 84%, respectively, and the MS and MSD recoveries for sample 72246 were 26% and 31%, respectively. Because the MS/MSD of sample 72096 met labo ratory control limits it was not flagged by the laboratory, but if the MS/MSD results for sample 72096 are reported, they should be flagged with an “F” qualifier.

Samples 72146, 72150, 72046, 72242, 71996, 72000, and the LRB had results that were

lower than the lowest calibration standard. Each of th ese results was flagged with a “J” qualifier because each result was less than the RL but greater than or equal to the MDL, and therefore the concentrations are approximate values. N o further qualifiers are needed.

TDS

Constant weight was not achieved after 3 drying cycles fo r all samples. It should be noted that the weight increased from the first weighing to th e second weighing for all samples except 72042, 72046, 71992, 72242, 72246, 71996, and 72000. Method 2540C warns that samples which contain high levels of calcium, magnesiu m, chloride, and sulfate may be hygroscopic meaning they absorb moisture from the air. FGD wastewater contains high concentrations of all of these species. This was likely the cause for the inconsistent weight calculations. Samples 72142, 72092, 72096, 72146, and 72150 were not qua lified, but results may be biased high.

The RPD for the laboratory duplicate from sample 72096 was 12%, which is not less than 10% as required by SM 2540C. The laboratory control limits a re 20%; therefore, the laboratory did not qualify the sample. The sample resu lt will be qualified as an estimated value as shown in Table 2. Laboratory duplicates were n ot performed in the other

batches.

### 6

TKN

TestAmerica performed MS/MSD analysis on samples 72096 and 72246. The percent recoveries for the MS and MSD for sample 72096 were 161% an d 147%, respectively, and 145% and 149% for the MS and MSD for sample 72246. These samp les did not meet the method control limits of 90-110%, nor the laboratory co ntrol limits of 54-131%. The sample concentration was greater than 4 times the spike amount in the MS and MSD samples, so TestAmerica stated that the percent recove ries and RPDs could not be reliably calculated. The associated LCS/LCSD were also acceptable, therefore, no additional data qualifiers are required.

TKN was detected in the calibration blanks. The results were greater than the MDL (0.077 mg/L), but less than the RL (1.0 mg/L). Because the re sults were less than the RL, no samples were qualified, but the CBs were flagged with a “J” qualifier.

TSS

The RPDs for the laboratory duplicates performed on sam ples 72142, 72096, 72046, and 72246 were greater than the method control criteria of 10%, at 11%, 18%, 22%, and 18%, respectively. The laboratory control criterion is 20 perc ent; therefore, samples 72142, 72096, and 72246 were not qualified by the laboratory. Sample 72046 and its duplicate were already qualified by TestAmerica with a “J” meaning t hat the result is an estimated
value because the result is below the RL, so no further qualification was necessary for this sample. Because the RPD was greater than the meth od control limits, sample 72142, 72096, and 72246 were qualified as estimated values.

### SUMMARY

The samples were prepared according to EPA Method 1631E to be analyzed by CVAFS.

There were no findings from the data review that required a dditional qualifiers in this

dataset.

SAMPLE RECEIPT, HANDLING, AND STORAGE ISSUES

There were no sample receipt issues in this data package.

INITIAL CALIBRATION

FGS performed the initial calibrations on each analysi s day. The initial calibration for the CVAFS analysis consisted of a blank and five calibrat ion standards with a correlation

coefficient ≥ 0.995. All method-specified criteria were met.

INITIAL AND CONTINUING CALIBRATION VERIFICATIONS

All initial and continuing calibration verifications (I CVs, CCVs) met method-specified

criteria.

BLANKS

All the preparation blanks or laboratory reagent blanks (L RBs) and the continuing calibration blanks (CCBs) met method-specified criteria. Some preparation blanks had mercury levels greater than the MDL (0.24 ng/L), but less t han the RL associated with each individual blank (different RLs based on preparation) . Because all of the blank results were less than the RL, no samples were quali fied based on these preparation blank

results.

DUPLICATES

No field duplicate samples were collected with these sa mpling episodes. Three samples were analyzed in duplicate at the laboratory, Bioreacto r Influent sample 72147, SBR Influent sample 72196, and Effluent sample 72247. The relative pe rcent difference (RPD)

### 3

for samples 72147, 72196, and 72247 were 9.74%, 4.36%, and 9.10%, respectiv ely. A sample from another work order was analyzed in duplica te with these batches that
resulted in an RPD of 79.7%, which is outside of the laborat ory’s criteria. The laboratory’s RPD criteria between analytical duplicates is 24%. No sample qualifications were needed based on these analytical duplicate results.

LABORATORY CONTROL SAMPLES

All laboratory control samples were within FGS’s contr ol limits of 80-120% recovery

and 24% RPD.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES (MS/MSD)

Matrix spikes (MS) and matrix spike duplicates (MSD) we re performed on samples 72097, 72147, and 72196. Additionally, an MS/MSD was performed on samp le 72296, which was a rerun from the long-term monitoring, month 2 set of samples. All aqueous MS/MSD recoveries were within method specifications of 71-125%. All RPDs met method-specified criteria.

DETECTION LIMITS

The laboratory MDL in the synthetic matrix was 0.239 ng/ L. Results below this MDL were reported as not detected (ND).

### SUMMARY

The samples were prepared for total metals analysis accor ding to TestAmerica’s “FGD ICP/MS SOP: Inductively Coupled Plasma Mass Spectrometry for Trace Elements Analysis in Flue Gas Desulfurization Wastewaters,” date d October 6, 2010, based on EPA Method 200.8, by ICP/MS analysis.

Any significant findings are summarized below. No addition al data qualifiers were required.

• One of the continuing calibration verifications (CCV) per formed on 12/21/2010

failed the method criteria for selenium.

• The matrix spike (MS) and matrix spike duplicate (MSD) rec overies for total silver for sample 72196 failed the EPA Method 200.8 control lim its of 70-130%. The MSD recovery for total silver for sample 72147 also fa iled the method

control limits.

• The MS/MSD relative percent difference (RPD) for tota l silver for samples 72147

and 72196 failed the FGD ICP/MS SOP control limits of ±20%.

• The post digestion spike (PDS) recoveries for copper, nic kel, and silver for sample 72147 failed TestAmerica’s control limits of 85–115%. The PDS recovery for silver for sample 71997 also failed TestAmeri ca’s control limits.

INTERNAL STANDARDIZATION

All internal standards used by TestAmerica were within th e method criteria.

### 3

INITIAL CALIBRATION

TestAmerica performed the initial calibrations on each analysis day. The initial calibration for the ICP-MS analysis consisted of a bla nk and four calibration standards.

INITIAL AND CONTINUING CALIBRATION VERIFICATION (IC V/CCV)

The initial calibration verifications (ICV) and CCV perf ormed by TestAmerica all had recoveries within the method criteria, except for seleniu m for one CCV on 12/21/2010. Samples associated with this CCV that had selenium value s less than the reporting limit were reported. Any samples with selenium values above the reporting limit were reanalyzed.

METHOD/INSTRUMENT BLANKS

All the method blanks were less than the reporting limit (RL); however, some elements were above the MDL and flagged with a “J” qualifier. No additional qualifiers were required for method blanks.

All instrument blanks (initial calibration blank (ICB) and continuing calibration blank (CCB)) were less than the RL; however, some element s were above the MDL and flagged with a “J” qualifier. No additional qualifiers were required for instrument blanks.

REPORTING LIMIT VERIFICATION STANDARD (CRI)

All CRI samples passed TestAmerica’s SOP control limi ts of 50–150% recovery.

LABORATORY CONTROL SAMPLES (LCS)

All LCS samples passed the method QC limits of 85–115% recov ery.

SYNTHETIC FGD INTERFERENCE CHECK SOLUTION

Based on TestAmerica’s SOP, all interference check sa mple A (ICSA) results had analytes of interest with concentrations less than the RL or less than five times the RL when known inherent contaminants are present in the stock solution used to make the

ICS.

All interference check sample B (ICSAB) synthetic sp ikes recovered within

TestAmerica’s SOP criteria of 70–130% of the true value.

SERIAL DILUTION

The serial dilution performed on samples 72147 and 72196 passed Te stAmerica’s criteria

of ±10% difference.

FIELD DUPLICATES

No field duplicate samples were collected with these sa mpling episodes.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES (MS/MSD)

MS and MSD were performed on samples of 72147, 72196, and 71997. The M SD of sample 72147 failed the method control limits of 70–130% recover y for silver at 69%, which was flagged with an “F” qualifier. The MS/MSD of sam ple 72196 failed the method control limits of 70–130% recovery for silver, which was flagged with an “F” qualifier. These silver failures are likely due to matrix interference from the high concentration of sulfates, which can form insoluble si lver sulfide and/or silver sulfate.

The silver recoveries in the associated LCS/LCSDs were acceptable. The RPD for the MS/MSDs for samples 72147 and 72196 failed the FGD ICP/MS SOP ± 20% control

limits for silver.

Otherwise, all MS/MSD spike recoveries were within th e method control limits of 70-

130% and the RPD for the MS/MSDs were within the FGD ICP /MS SOP control limits of ±20 percent. No additional data qualifiers were required.

POST DIGESTION SPIKES (PDS)

The PDS performed on samples 72147 and 71997 passed TestAmerica’s control limits of 85–115% recovery for all analytes, except for copper, nickel, and silver for PDS sample 72147 and silver for PDS sample 71997, which were flagged with a “W ” qualifier. No additional data qualifiers were required.

DETECTION LIMITS

The laboratory performed an MDL study in the synthetic F GD wastewater matrix, instead of reagent water.

### SUMMARY

The samples were prepared for total metals analysis acc ording to TestAmerica’s SOP for ICP Analysis for Trace Metals by Method 200.7. Any signific ant findings are summarized below. Additional data qualifiers were require d (see Table 2).

• The serial dilution for cobalt, iron, and zinc for sa mple 72143 failed TestAmerica’s SOP control limit of percent differenc es less than 10%.

• The post digestion spike (PDS) for calcium, iron, magn esium, and zinc for sample 72143 failed TestAmerica’s control limits of 85–115% recovery.

• The PDS for manganese for sample 72147 failed TestAmerica ’s control limits of 85–115% recovery.

SAMPLE RECEIPT, HANDLING AND STORAGE ISSUES

The samples associated with Episode 6569 (72192, 72196, 72200, 72205, and 72209) did not have a sample date or time on the traffic report.

INTERNAL STANDARDIZATION

While the internal standard (ISTD) yttrium was used for these analyses, no checks for the

ISTD recoveries within the ±30% criterion of the calibra tion blank as per Section 9.11 of

the SOP were seen. All ISTD were within the control limits.

INITIAL CALIBRATION

TestAmerica performed the initial calibrations on each analysis day. The initial calibration for the ICP analysis consisted of a blank an d one calibration standard.

### 3

INITIAL AND CONTINUING CALIBRATION VERIFICATIONS

The initial calibration verifications (ICV) and continu ing calibration verifications (CCV) performed by TestAmerica all had recoveries within the m ethod criteria.

METHOD/INSTRUMENT BLANKS

All the method blanks were less than the reporting limit (RL); however, some elements were above the method detection limit (MDL) and were f lagged with the “J” qualifier.

All instrument blanks (initial calibration blank (ICB) and continuing calibration blank (CCB)) were less than the RL; however, some element s were above the MDL and were flagged with the “J” qualifier.

REPORTING LIMIT VERIFICATION STANDARD (CRI)

All CRI samples passed TestAmerica’s SOP control limi ts of 50–150% recovery.

LABORATORY CONTROL SAMPLES (LCS)

All LCSs passed the method control limits of 85–115% recover y.

INTERFERENCE CHECK SOLUTIONS

Interference checks were performed using the synthetic m atrix as the check solution. All data quality objectives met TestAmerica’s SOP criteria.

SERIAL DILUTION (SRD)

Serial dilutions were performed for each batch of total samples. All serial dilution percent differences were less than 10% as required by TestAmeric a’s SOP, except for cobalt, iron, and zinc for sample 72143, which were flagged with a “ V” qualifier.

FIELD DUPLICATES

No field duplicate samples were collected with these sa mpling episodes.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES (MS/MSD)

Matrix spikes (MS) and matrix spike duplicates (MSD) w ere performed on the total samples of 72143, 72147, and 72196. Some elements with high concent rations failed the EPA 200.7 Method spike recovery control limits of 70–130% but w ere flagged with a “4” qualifier indicating that the concentration in the paren t sample was greater than 4 times the spike and could not be reliably calculated. These data were considered acceptable based on the LCS passing the method control limits. Othe rwise, all MS/MSD spike

recoveries were within the method control criteria of 70-130%. The RPD for all

### 4

MS/MSDs were within TestAmerica’s ± 20% requirement. No additional data qualifiers

were needed.

POST DIGESTION SPIKE (PDS)

The PDS performed on sample 72143 passed TestAmerica’s cont rol limits of 85–115% recovery for all analytes except aluminum, boron, calc ium, iron, magnesium, titanium, and zinc. Calcium, magnesium, and zinc were qualified with a “W”. Calcium and magnesium did pass in the matrix spike for this sample. Aluminum, boron, iron and titanium failed the PDS; however, the percent recoveri es were not calculated by the laboratory because their concentrations were greater than 4 times the PDS spike level. Aluminum, boron, and titanium passed TestAmerica’s requir ement of percent differences less than 10% for the serial dilution for this sample demo nstrating that there were no significant matrix interference with these elements. Iron and zinc failed TestAmerica’s requirements for the serial dilution; therefore, based on these cumulative results, iron and zinc are being qualified as suspect due to matrix interfere nce. These additional qualifiers appear in Table 2.

The PDS performed on sample 72147 passed TestAmerica’s cont rol limits of 85–115% recovery for all analytes except boron and manganese. Manganese was qualified with a “W”. Boron failed the PDS; however, the percent recov ery was not calculated by the laboratory because its concentration was greater the 4 times the PDS spike level. Both boron and manganese passed TestAmerica’s requirement of percent differences less than 10% for the serial dilution for sample 72147 demonstrating th at there were no significant matrix interferences. No additional qualifier is requir ed due to this PDS.

The PDS performed on sample 72196 passed TestAmerica’s cont rol limits of 85–115% recovery for all analytes except boron and manganese; however, the percent recoveries were not calculated by the laboratory because their co ncentrations were greater than 4 times the PDS spike level. Both boron and manganese passed TestAmerica’s requirement of percent differences less than 10% for the serial dil ution for sample 72196 demonstrating that there were no significant matrix int erferences. No additional qualifier is required due to this PDS.

DETECTION LIMITS

The laboratory performed an MDL study in the synthetic F GD wastewater matrix, instead of reagent water.

SUMMARY

All samples were analyzed within the holding time specif ied in 40 CFR 136 Table II unless otherwise noted below. All samples were preserve d appropriately unless otherwise specified below. Samples 72192, 72196, and 72200 had no colle ction dates or times listed on the traffic report, and were given the date of relinquishment. Many of the traffic reports did not have receipt temperatures.

Field duplicate samples were not collected for this epis ode. Depending on the method, a laboratory duplicate was analyzed instead. The Relative Percent Difference (RPD) between the sample and its duplicate was less than 20% unl ess otherwise noted below.

If applicable, the appropriate number of standards was used to create a calibration curve. If sample results were above the highest standard used t o create the curve, the sample was diluted and reanalyzed. All sample results were between the lowest and highest standards unless noted below. Additionally, unless otherwise noted, a ll calibration blanks and calibration verification samples met the criteria sp ecified in the method.

If required by the method, the quality control sample (QC S), a secondary source standard used to verify calibration, was always within the cont rol limits specified by the method.

As described below, the analyte of interest was detecte d above the method detection limit (MDL) in some laboratory reagent blanks (LRB). However , the analyte of interest was never detected above the reporting limit (RL) in the LRBs . If required by the method, all laboratory fortified blanks (LFB) met the criteria spec ified in the method unless specified

below.

If required by the method, a matrix spike (MS) analysis was run on sample 72147 and sample 72196 for each analyte to check for matrix interfe rences. All MS samples analyzed met the criteria specified in the method unless described below.

DATA NOTES/ISSUES

Ammonia

The result for the method blank associated with one of the batches was greater than the MDL. All associated samples were flagged with a “B” qualif ier. This affects samples 72147, 72143, 72093, 72097, and 72151. No further action is required.

The percent recoveries for the MS and matrix spike dupli cate (MSD) for sample 72147 were 93% and 102%, respectively, which is within the method co ntrol criteria; however, the results exceeded the calibration range. These MS a nd MSD and results were flagged with an “E” qualifier.

BOD 5



### TestAmerica analyzed five dilutions, but no dilutions had a dissolved oxygen (DO) depletion greater than 2.0 mg/L for samples 72143, 72151, 72043, 71993, a nd 72247. Therefore, BOD 5 

### was reported as not detected for these samples. Additiona lly, for sample 72200, the dilutions did not have a residual DO criteria of gre ater than 1.0 mg/L; therefore, BOD 5 

### was reported as not detected for this sample. The rest of the samples had at least one dilution with a DO depletion greater than 2.0 mg/L. As required in the method, the final result was calculated by taking the av erage of the results for all dilutions with a DO depletion greater than 2.0 mg/L and a final DO greater than 1.0 mg/L.

Chloride and Sulfate

MS and MSD were performed on samples 72147 and 72196. The MS/MS D recoveries for both samples were within the method control for both chloride and sulfate; however,

the MS and MSD results for chloride exceeded the calibra tion range. Both sets of MS/MSD results were flagged with “E” qualifiers.

COD

MS and MSD were performed on samples 72147 and 72196. The MS a nd MSD recoveries for sample 72147 were 66% and 71%, respectively, w hich is outside the

method control criteria. These MS/MSD results were flagged with an “F” qualifier. The MS and MSD recoveries for sample 72196 were 72% and 70%, respec tively, which is

outside the method control criteria. These MS/MSD re sults were flagged with an “F” qualifier.

Cyanide

Because of the nature of the sample matrix, all of th e samples in this sampling episode used a lower volume, which resulted in elevated RLs being ca lculated and reported by TestAmerica with the sample results.

### 4

MS and MSD were performed on samples 72147 and 72196. The MS a nd MSD recoveries for sample 72147 were 76% and 75%, respectively. T he MS and MSD recoveries for sample 72196 were 59% and 57%, respectively. Th e LCS/LCSD recoveries associated with these batches were acceptabl e, which indicates the analytical system was operating within control. Additionally, ther e is no method requirement for the analysis of a MS/MSD and therefore, no corrective ac tion is necessary.

Nitrate/Nitrite

No MS/MSD data was reported for batch 45200 in the sample a nd QC sample report summary. The method requires that a known amount of ana lyte be added to 10% of samples per batch. The general chemistry worksheet indi cates that MS samples were performed on a sample outside of these episodes, but no spiking concentrations or percent

recoveries are indicated. The MS/MSD recoveries for the other batches were within

control limits.

Phosphorus

The results for the method blanks associated with two of the batches was greater than the MDL, but less than the RL. The blank results were flagge d with a “J” qualifier. All associated samples were qualified with a “B” flag. No additional corrective action is

necessary.

MS and MSD were performed on sample 72001, 72147 and 72196. The percen t recoveries for the MS and MSD for sample 72147 were 69% an d 70%, respectively,

which is outside the method control criteria. These MS /MSD results were flagged with an “F” qualifier. The LCS/LCSD recoveries for this ba tch were acceptable and indicate that the analytical system was operating within control . The percent recoveries for the MS and MSD for sample 72196 were 91% and 85%, respectively. The MSD recovery is
outside the method control criteria, but within the labor atory criteria and therefore, was not flagged. If reported, the MSD result should be flagge d with an “F” qualifier. The LCS/LCSD recoveries for this batch were acceptable and ind icate that the analytical system was operating within control. Additionally, the MS/MSD performed on sample 72001 was in the same batch as the MS/MSD for 72196 and the pe rcent recoveries for the MS and MSD were 96% and 97%, respectively, with are within th e method control

criteria.

TDS

TA reports that constant weight was not achieved after 3 drying cycles for the following samples: 72097, 72143, 72147, 72151, 71993, 72196, 72200, 71997, 72004, and 72243. Review of the general chemistry worksheets indicates th at constant weight was achieved for all samples. No further action was necessary.

### 5

Because of the nature of the sample matrix, some of t he samples in this sampling episode used a lower volume, which resulted in elevated RLs being ca lculated and reported by TestAmerica with the sample results.

The analytical duplicate associated with sample 72143 excee ded the recovery criteria. The duplicate result was qualified with an “F” flag. Beca use an analytical duplicate was not required by the method, no further corrective action i s necessary.

TKN

MS and MSD were performed on samples 72147 and 72196. The MS a nd MSD recoveries for sample 72147 were 76% and 57%, respectively. The concentration in the original sample was greater than four times the spike a mount; therefore, the recoveries cannot be reliably calculated and the results were flagge d with a “4” qualifier. The MS and MSD recoveries for sample 72196 were 81% and 78%, respecti vely, which do not meet the method control criteria, but do meet the labo ratory control criteria and therefore, these results were not flagged by the laboratory. If r eported, the MS and MSD results should be flagged with “F” qualifiers. The LCS/LCSD reco veries associated with these batches were acceptable, which indicates the analytical system was operating within

control.

TSS

Because of the nature of the sample matrix, some of t he samples in this sampling episode used a lower volume, which resulted in elevated RLs being ca lculated and reported by TestAmerica with the sample results.

### SUMMARY

The samples were prepared according to EPA Method 1631E to be analyzed by CVAFS. There were no findings from the data review that required a dditional qualifiers in this dataset. The following summarizes the findings from the data review:

• The sample number for Sample 72157 was labeled incorrectly o n the traffic

report.

• The sample description for Sample 72148 was entered incorrec tly by FGS at the time of sample receipt.

• Two laboratory duplicates were out of the method-suggested relative percent difference (RPD) criteria.

SAMPLE RECEIPT, HANDLING, AND STORAGE ISSUES

Sample 72157 was labeled incorrectly as Sample 721557 in the tra ffic report submitted to the laboratory. The error was identified and correct ed during the data review based on the sample description. FGS incorrectly labeled Sampl e 72148 as the FGD Bioreactor Effluent, Set 4, when the correct sample description is FGD Bioreactor Influent, Set 4. This error was identified and corrected during the data review and confirmed based on the traffic report.

INITIAL CALIBRATION

FGS performed the initial calibrations on each analysi s day. The initial calibration for the CVAFS analysis consisted of a blank and five calibrat ion standards with a correlation

coefficient ≥ 0.995. All method-specified criteria were met.

INITIAL AND CONTINUING CALIBRATION VERIFICATIONS

All initial and continuing calibration verifications (I CVs, CCVs) met method-specified

criteria.

BLANKS

All the preparation blanks or laboratory reagent blanks (L RBs) and the continuing calibration blanks (CCBs) met the method-specified crite ria. Because all of the blank results were less than the RL, no samples were quali fied based on these preparation blank

results.

DUPLICATES

No field duplicate samples were collected with these sa mpling episodes. Four samples were analyzed in duplicate at the laboratory, Influent s amples 72144 and 71994 and Effluent samples 72048 and 72298. The relative percent differenc e (RPD) for samples 72144, 71994, 72048, and 72298 were 30.6%, 7.66%, 19.4% and 43.9%, respectively. Two of these RPDs were outside of laboratory criteria . The samples from another sampling episode were also analyzed in duplicate with RPD s of 13.3%, 22.4%, and 3.03%. The laboratory’s RPD criteria between analytica l duplicates is 24%. Analytical duplicates are not a method requirement; therefore, no samples were qualified based on analytical duplicates.

LABORATORY CONTROL SAMPLES

All laboratory control samples were within Frontier’s control limits of 80-120% recovery

and 24% RPD.

MATRIX SPIKE AND MATIX SPIKE DUPLICATES (MS/MSD)

Matrix spikes (MS) and matrix spike duplicates (MSD) were performed on Influent sample 72144 and Effluent samples 72048 and 72298. MS/MSDs were also performed on samples from another sampling episode. All aqueous MS /MSD recoveries were within method specifications of 71-125%. All RPDs met metho d-specifiec criteria.

DETECTION LIMITS

The laboratory MDL in the synthetic matrix was 0.239 ng/ L. Results below this MDL were reported as not detected (ND).

SUMMARY

All samples were analyzed within the holding time specif ied in 40 CFR 136 Table II. All samples were preserved appropriately. BOD analysis was not performed on sample 72348 because it was received after the hold time had expire d.

Field duplicate samples were not collected for these ep isodes. Depending on the method, a laboratory duplicate was analyzed, instead. The Relati ve Percent Difference (RPD) between the sample and its duplicate was less than 20% unl ess otherwise noted below.

If applicable, the appropriate number of standards was used to create a calibration curve. If sample results were above the highest standard used t o create the curve, the sample was diluted and reanalyzed, unless otherwise specified below. A ll sample results were between the lowest and highest standards unless noted below. Additionally, unless otherwise noted, all calibration blanks and calibration verification samples met the criteria specified in the method.

If required by the method, the quality control sample (QC S), a secondary source standard used to verify calibration, was always within the cont rol limits specified by the method

unless otherwise noted below.

As described below, the analyte of interest was detecte d above the method detection limit (MDL) in some laboratory reagent blanks (LRB). However , the analyte of interest was never detected above the reporting limit (RL) in the LRBs . If required by the method, all laboratory fortified blanks (LFB) met the criteria spec ified in the method.

If required by the method, a matrix spike (MS) sample wa s analyzed on samples 72344, 72346, or 72348 for each analyte to check for matrix interfere nces. MS samples analyzed met the criteria specified in the method unless described otherwise below.

DATA NOTES/ISSUES

Ammonia

A MS and matrix spike duplicate (MSD) were performed on sample 72346. The percent recoveries were 130% and 127%, respectively, which are above the method specific control limit of 90-110%. These MS/MSD results were flagg ed with a “4” qualifier because the analyte present in the original sample is f our times greater than the matrix spike concentration; therefore, the control limits a re not applicable. No further qualification is necessary.

A MS and MSD were also performed using sample 72348. The percen t recoveries for the MS and MSD were 120% and 113%, respectively, which is greater than the control limits. Both the MS and MSD were flagged with “F” qualifie rs.

### 3

BOD 5



### TestAmerica analyzed five dilutions; the dilutions had d issolved oxygen (DO) depletions greater than 2.0 mg/L for samples 72345, 72346, and 72347. As required in the method, the final result was calculated by taking the average of the results for all dilutions with a DO depletion greater than 2.0 mg/L and a final DO greater t han 1.0 mg/L.

Chloride and Sulfate

Samples 72345, 72346, 72347, and 72348 had results below the lowest calibra tion standard. All of these samples had results that were gr eater than the MDL, but less than the RL; therefore, the samples were flagged with a “J ” qualifier. No further qualification is required.

COD

A MS and MSD were performed for sample 72344. The MSD perce nt recover was 80%,

which is outside the method criteria. The MSD result wa s flagged with an “F” qualifier. No further qualification is necessary.

Sample 72348 had a result below the lowest calibration st andard, but this result was greater than the MDL, but less than the RL and theref ore, was flagged with “J” qualifier. No further qualification is necessary.

Cyanide

The calibration was performed using standards ranging from 0.00 ppb to 400.0 ppb. The method states that the appropriate range of calibration standard concentrations for this method is between 5 ppb and 20 ppb. All samples in which cy anide was detected had

results ≥ 20 ppb.

MS/MSDs were performed using samples 72344 and 72346. The percent re coveries for the MS and the MSD for sample 72344 were 43% and 45%, respecti vely. The percent recovery for both the MS and the MSD for sample 72346 was 88%. The percent

recoveries for both sets of MS/MSDs are below the c ontrol limit of 90% and as a result the MS/MSDs were flagged with “F” qualifiers.

Nitrate/Nitrite

Samples 72345, 72346, 72347, and 72348 had results below the lowest calibra tion standard. These results were greater than the MDL, but less than the RL and therefore, the results were flagged with “J” qualifiers. No further qualification is necessary.

The data report narrative for nitrate/nitrite indicate s an incorrect sample ID (72493) as requiring a dilution. No such sample is included in this ep isode.

### 4

Phosphorus

The LRB results for both batches of samples had phospho rus concentrations greater than the MDL at 0.0154 mg/L for batch 51117 and 0.0106 mg/L for batch 51477; how ever the
results were below than the RL. Therefore, the LRB r esults were flagged with “J” qualifiers and all samples that contained the analyte were flagged with “B” qualifiers. All

calibration blank results were also above the MDL but le ss than the RL, and therefore, were also flagged with “J” qualifiers.

Samples 72345, 72346, 72347, and 72348 had results that were lower than t he lowest calibration standard. These results were greater than the MDL, but less than the RL and therefore, were flagged with a “J” qualifier. No further qualifiers are needed.

TDS

Constant weight was not achieved after 3 drying cycles f or the samples. It should be noted that the weight increased from the first weighing to the second weighing and/or second weighing to third weighing for samples 72344, 72347, 72343, 72346, 72345, a nd 72342. Method 2540C warns that samples which contain high levels of calcium, magnesium, chloride, and sulfate may be hygroscopic meaning they absorb moisture from the air. The concentrations of all of these specie s may be high in these samples; and so this was likely the cause for the inconsistent wei ght calculations. These samples were not qualified, but results may be biased high.

The RPD for the laboratory duplicate from sample 72347 was 67%, which is greater than the 10% control limit required by SM 2540C. The sample was not qualified, but the duplicate was flagged with a “J” qualifier because the duplica te result was greater than the MDL, but less than the RL.

TKN

The LRB results for batch 53496 had a TKN concentration gr eater than the MDL at 0.389 mg/L; however the results were below the RL. The LRB result was flagged with a “J” qualifier and sample 72348 was flagged with a “B” qualifier. The initial calibration blank

results for both batches were also above the MDL but less than the RL at 0.375 mg/L for batch 51337 and 0.378 mg/L for batch 53692, and therefore were also f lagged with “J” qualifiers.

TestAmerica performed MS/MSD analyses on sample 72346. The percent recoveries for the MS and MSD samples were 377% and 378%, respectively. Th e MS and the MSD did not meet the method control limits of 90-110%, so they wer e flagged with “F” qualifiers. No further qualification is necessary.

TSS

No issues were identified by data reviewer.
