# The Engineering and Analysis Division (EAD) of the U.S. Environmental Protection

Agency (EPA) is conducting a sampling program at steam electric power plants. The sampling

program will characterize raw wastewaters generate d by coal-fired steam electric power plants

and evaluate treatment technologi es and best management practic es used to reduce pollutant

discharges. This Sampling Episode Report (SER ) describes the sampling activities that took

place July 11 - 16, 2010, at Duke Energy’s Miami Fo rt Station (Miami Fort), located in North

Bend, Ohio (Sampling Episode 6560). The focus of Episode 6560 was to characterize the purge

stream entering the flue gas desulfurization (FGD ) wastewater treatment system and the effluent

from the chemical precipitation system.

1.1 Background of Detailed Study

During EPA’s recently completed detailed study of the steam electric industry, EPA

identified metals and certain other constituents pr esent in the wastewater discharges from steam

electric power plants that substantially cont ribute to the toxic load ings for the industry.

Additionally, EPA determined that one of the wa ste streams contributing most of these toxic

loadings are associated with wet FGD systems pr esent at coal-fired power plants. Based on these

findings, EPA has focused the sampling progr am on characterizing the untreated FGD

wastewaters and effluent quali ty from technologies designed to treat the wastewater.

1.2 Power Plant Site Selection

EPA selected steam electric plants for F GD wastewater sampling based on the process

configurations and characte ristics of the plants.

Miami Fort was selected by EPA for sampling based on the following site characteristics:

 The plant is a coal-fired pow er plant that burns eastern bituminous coal in each of

its three generating units;

 The plant operates limestone forced oxidation wet FGD systems on two of the

three generating units;

 The plant operates a segregated FGD wastewater treatment system, which

includes the following steps:

— Equalization and pH adjustment (lime addition),

— Organosulfide addition,

— Ferric chloride addition (discontinue d prior to the sampling episode),

— Polymer addition,

— Clarification;

 The plant operates selectiv e catalytic reaction (SCR) systems on two of the three

generating units (the same two that have associated FGD systems); and

 

# The plant produces a commerc ial-grade gypsum by-product.

# 1-2 1.3 Sampling Episode Overview

EPA and its technical contractor, Eastern Research Group, Inc. (ERG) conducted a oneday pre-sampling site visit at Miami Fort on Ma rch 1, 2010 as part of the detailed study. The

information collected during the pre-sa mpling site visit was used to create Sampling Plan, Duke

Energy’s Miami Fort Station (Sampling Plan) [1], which describes the sample collection

procedures used during the sampling episode.

On Sunday, July 11, 2010, EPA arrived at Miami Fort to meet with plant personnel,

receive on-site safety training, review the sa mpling points, and determine the set-up for the

sample collection. EPA and ERG collected the samples specified in the Sampling Plan on

Monday through Friday (July 12 - 16, 2010). The following personnel participated in EPA’s

sample collection activities:

 

# Ron Jordan, EPA/EAD;

 

# Jezebele Alicea, EPA/EAD;

 

# Holly Cannon, ERG;

 

# TJ Finseth, ERG;

 

# Lydia Lambert, ERG;

 

# Jennifer Lewis, ERG; and

 

# Jessica Wolford, ERG.

In addition, during the sample collection, EPA collected split sample s with the Utility

Water Act Group (UWAG). UWAG is a trade asso ciation for the electric power generating

industry. During the sampling epis ode, UWAG acted as Miami Fort’s representative and

collected samples on be half of the plant.

# O VERVIEW



# Miami Fort operates three baseload steam el ectric generating units and each has a coalfired boiler. Unit 6, which began operation in 1960, has a generating capacity of 175 MW. Units

7 and 8, which began operation in 1975 and 1978, re spectively, each has a ge nerating capacity of

550 megawatts (MW). All three generating units burn eastern bituminous coal. The plant is

located in North Bend, Ohio, approximately 20 mile s west of Cincinnati, and discharges to the

Ohio River.

Approximately three years ago, Miami Fort retr ofitted Units 7 and 8 (but not Unit 6) with

FGD scrubber systems to control the sulfur dioxide (SO 2 

# ) releases from the plant. The removal

efficiency of both FGD systems is approximately 96 percent. In addition to the FGD scrubber

systems, Miami Fort installed an FGD wastewater treatment system to control the discharges of

the wastewater generated during the operation of the FGD scrubbe rs. Sections 2.1 and 2.2 further

discuss the FGD scrubber systems and the FGD wastewater treatment system, respectively.

Miami Fort retrofitted Units 7 and 8 with SCR systems in 2003 and 2001, respectively.

The plant operates the SCR systems, which are used to control nitrogen oxide (NO X 

# ) emissions

from the plant, year round.

The electrostatic precipitators (ESPs) at Miam i Fort are particulate control devices that

are designed to remove greater than 99 percent of the fly ash and other particulates from the flue

gas. Miami Fort utilizes ESPs to remove the fl y ash from all three units. The fly ash and other

particulates are collected in hoppe rs. The fly ash from Unit 6 is wet sluiced to the plant’s ash

pond. The fly ash from Units 7 and 8 is pneumati cally conveyed to storage silos. Miami Fort

sells most of the ash to Ready Mix. Any fly ash th at the plant cannot sell is transferred to their

landfill located approximately th ree miles away, which is owne d and operated by Duke Energy.

Miami Fort previously had issues with blue plume from the stack, associated with sulfur

trioxide emissions. The plant now injects lime into the flue gas between the air heater and the

ESP to control the sulfur trioxide emissions.

Miami Fort operates an ash pond with two adj acent cells operated in series. Fly ash from

Unit 6 and bottom ash from all three units are slui ced to the cell nearest the plant. Polymer is

added to the ash pond near where the sluicing pi pes deposit the ash sluice to improve total

suspended solids (TSS) removals. The plant operat es the first cell using equipment to maintain

channels for the sluice water to move through th e mass of ash solids coll ected in the pond (i.e.,

the rim ditch stacking method). The plant removes the solids that settle out in the channels of the

ash pond and stacks them in piles along the perimete r of the ash channels to allow the solids to

dewater, while the water drains back into th e pond. After the solids ha ve been dewatered, the

plant hauls them to the landfill for disposal. In ad dition to fly ash and bottom ash transport water,

the ash pond also receives treated FGD wastewater and mill rejects. The ash pond discharges to

the Ohio River via Outfall 002.

Unit 6 at Miami Fort has the following configuration:

 

# Boiler;

 

# Air heater; and

 

# ESP.

# 2-2 Units 7 and 8 at Miami Fort ha ve the following configuration:

 Boiler;

 SCR system;

 Air heater;

 Lime injection;

 ESP; and

 FGD scrubber system.

2.1 FGD Scrubber Systems

Miami Fort operates two identical wet FGD scr ubber systems that treat the flue gas from

Units 7 and 8. The plant uses limesto ne slurry as the sorbent for SO 2 

# absorption. Limestone and

service water are fed to on-site ball mills, whic h pulverize the limestone to create the slurry.

From the ball mills, the slurry is transferred to hydrocyclones to collect limestone particles that

are too large to use in the FGD scrubber sy stem. The underflow from the hydrocyclones is

returned to the ball mills for additional proce ssing. The overflow from the hydrocyclones, which

is between 20 and 30 percent solid s (by weight), is transferred to the limestone slurry feed tank

and used as fresh limestone slurry in the abso rber. Miami Fort also uses lime residual, a

byproduct from the lime softening process at the City of Hamilton water treatment plant, to make

the slurry for the FGD process. The lime resi dual accounts for approximately 10 percent of the

slurry used in the two units.

The fresh limestone slurry is fed to the r eaction tank of the FGD system and the recycle

pumps transfer the slurry to the various levels of the FGD scrubber (typi cally two of the three

spray levels are operating at one time). The slurry is pressurized and sprayed downward into the

scrubber vessel through the spray nozzles. As the slurry falls downward and the flue gas flows

countercurrent to the slurry, the spray droplets of the limestone slurry contact the flue gas and

absorb the SO 2 

# , which reacts with the limestone particle s and produces calcium sulfite. The spray

droplets flow downward until they se ttle on the first of two dual flow trays, forming a layer of

slurry that the flue gas must pass through to exit the FGD system. The tray has small holes in it

that allow the flue gas to bubble through the limestone slurry la yered on the tray, which provides

additional contact between the limestone slurry a nd the flue gas. The spray droplets fall to the

second dual flow tray and then continue to flow downward in the scrubb er until they reach the

reaction tank. Miami Fort bubbles air through the reaction tank to oxidize the calcium sulfite to

calcium sulfate (i.e., gypsum).

Miami Fort operates the FGD system to main tain a set sulfur di oxide removal of 97

percent. The system automatically adjusts the slurry feed rate to achieve this removal, which also

adjusts the pH in the FGD system. The pH in the FGD system is typically around 5 S.U. In

addition, the plant operates the system to maintain a solids concentration in the scrubber of 21 to

24 percent weight solids. When the solids conc entration exceeds 24 percent, the plant blows

down some of the gypsum slurry from the scrubb er. Miami Fort also blows down some of the

gypsum slurry to control the chlorides concen tration. The chlorides concentration in the

scrubbers is maintained at approximately 5,000 to 10,000 parts per million (ppm), with a design

maximum chlorides concentration of 12,000 ppm. Miami Fort transfers the blowdown from the

scrubbers to the gypsum dewatering operations.

# 2-3 Each FGD system has its own gypsum dewateri ng equipment; therefore, the Unit 7 and 8

gypsum and wastewater are not commingled until the FGD wastewater treatment system. The

gypsum slurry for each scrubber is pumped to its primary hydrocyclone, where the solid gypsum

is separated from the water by centrifugal force. Th e solid gypsum is forced outward to the walls

of the hydrocyclones and falls downward, while the water exits the top of the hydrocyclones.

The gypsum from the primary hydrocyclones is tran sferred to the vacuum belt filters for final

dewatering. The overflow from the primary hydr ocyclones is transferred to secondary

hydrocyclones. The overflow from the second hydrocyclones is transferred to the FGD

wastewater treatment system. Th e underflow from the secondary hydrocyclones is sent to the

reclaim tanks, which are segregated for each unit, a nd is reused in the process as make-up water.

As the gypsum is applied to the vacuum belt filters, Miami Fort wa shes the gypsum with

service water to reduce the chlorides in the gypsum to less than 100 ppm. The vacuum belt filters

dry the gypsum to a moisture cont ent of less than nine percent. The gypsum produced at the plant

is then sold to Lafarge for wallboard manufact uring. If the gypsum is off-specification or if

Lafarge refuses to accept the gypsum, the plant ca n also market the gypsum to the agricultural

industry.

2.2 FGD Wastewater Treatment System

The Miami Fort FGD wastewater treatment system is designed to receive intermittent

transfers of wastewater (seconda ry hydrocyclone overflow) from the FGD system at a maximum

design flow rate of 200 gallons per minute (gpm). The actual flow rate through the system

averages 150 gpm over a 24-hour period. The F GD wastewater treatment system, designed by

Infilco Degremont, is a chemical precipitation treatment system and contains the following

treatment operations:

 Equalization and pH adjustment (lime addition);

 Organosulfide addition;

 Polymer addition; and

 Clarification.

The secondary hydrocyclone overflow from the scrubbers is transferred directly to the

equalization tank at the beginning of the wast ewater treatment system. During the sampling

episode, the FGD influent wastew ater was found to contain 1.6 to 3.0 percent solids, had a pH

between 5 and 7 S.U., and a temperature betwee n 47 and 54 °C. Miami Fort adds lime to the

equalization tank to raise the pH in the tank to between 8.4 and 8.6 S.U. to precipitate the soluble

metals as insoluble hydroxides and oxyhydroxides. The equalization tank also receives water

from the wastewater treatment building sump, which primarily consists of filter press filtrate, and

flush water from the flushi ng of the sludge lines.

From the equalization tank, the wastewat er enters the coagulation tank, where

organosulfide is added. The organosulfide is ad ded to precipitate residual metals as sulfide

complexes. At the time of the presampling site vis it, Miami Fort stated that they were testing the

Nalco Nalmet® 1689 organosulfide in the FGD wast ewater treatment system in place of TMT

15®. Miami Fort tested the effectiveness of th e Nalmet® 1689 by adjusti ng the feed rate and

addition amounts, in combination with other FGD wastewater treatment additives (i.e., polymer,

ferric chloride). Before the sampling episode , the plant optimized the use of Nalmet® 1689,

# 2-4 which effectively lowered mercury levels and elim inated the need to add ferric chloride to the

wastewater treatment system.

Flow from the coagulation tank splits into two parallel stream s that flow to two

DensaDeg® clarifiers. This type of clarifier ha s an initial reactor se ction, where polymer is

added for coagulation and flocculation to improve solids removals. From the reactor section, the

wastewater enters the clarification/thickening secti on of the clarifier, where the solids settle out

of the wastewater. The sludge is transferred to the sludge holding ta nk and then processed

through the filter presses. The filtrate from the f ilter presses is collect ed in the wastewater

treatment building sump and recycled to the equa lization tank. The sludge fr om the filter presses

is hauled off site for disposal at a different landfill from the one us ed for the disposal of the ash.

The clarified wastewater from the two DensaDeg ® clarifiers is combined in the effluent

tank. The wastewater is pumped to the ash pond a nd discharged via Outfa ll 002. The transfers to

the ash pond are based on level control within the effluent tank and are th erefore not continuous.

Figure 2-1 presents the process flow diagram of the FGD wast ewater treatment system, as

well as the sampling points for the Miami Fort sa mpling episode, which are summarized below:

 

# A sample of the purge stream entering the FGD wastewater treatment system

upstream of the equalization tank (i.e., the sample was collected prior to any

chemical addition or mixing with recycle streams);

 

# A sample of the effluent from the effl uent tank downstream of coagulation and

clarification, just before the treate d effluent is sent to the ash pond.

# During the Miami Fort sampling episode, the sampling team followed the collection

protocols specified in the Sa mpling Plan. Section 3.1 describes the sampling points, sample

collection methods, and field measurements. Secti on 3.2 describes the list of analytes and the

sample preservation procedures. Section 3.3 discu sses the plant operational data collected during

the sampling episode. Finally, Section 3.4 discusse s any deviations from the planned sampling

activities.

3.1 Sampling Points, Sample Collectio n Methods, and Field Measurements

This section describes the sampling point s, sample collection methods, and field

measurements. Additional details are available in Section 3 of the Sampling Plan. Figure 2-1 of

this report presents a flow diagram of the plant’s wastewater treat ment system, including

sampling point locations.

Table 3-1 lists the sampling points, sampli ng point descriptions, type of sample

collection, and sample collection dates and times. Table 3-2 list s the sampling point numbers and

descriptions, the number of samples collected, and the pollutant parameters for which the

samples were analyzed. Table 3-3 presents th e field measurement data collected from each

sampling point. Table 3-4 presents a crosswalk be tween the sample numbers used for laboratory

sample identification and the sample points for each day.

The sampling points for this episode were:

 

# SP-1 Influent to FGD Wastewater Treatment System;

 

# SP-2 Effluent from FGD Wast ewater Treatment System;

 

# SP-3 Duplicate of Effluent from FGD Wastewater Treatment System (SP-2);

 

# SP-4 Influent to FGD Wastewater Treatme nt System (SP-1) Field Blank; and

 

# SP-5 Effluent from FGD Wa stewater Treatment System (SP-2) Field Blank.

For all the sampling points, EPA collected spl it samples with Miami Fort’s representative

by inserting a “Y” splitte r into the sample tubing configurat ion at each sampling point to allow

for split sample collection. EPA collected all samples (other than mercury and cyanide) at all

sampling points as “true” splits (i.e., samp les for the same analyte were collected

simultaneously). The mercury and cyanide samples were collected directly from a sample tap;

therefore, for these samples, EPA and Miami Fo rt’s representative collected duplicate samples,

with one filling the bottle im mediately after the other.

At each of the sampling points, EPA collected metals sample fractions following EPA

Method 1669 collection protocols. To collect these samples, EPA samplers donned Tyvek®

coveralls and dust masks (dust masks were worn until all mercury samples had been collected).

In addition, EPA set up a “cleanbox,” which consists of a portable plastic rectangular box with a

shallow lip and a flip-top lid th at secures itself ope n with clips. The “cleanbox” is double-bagged

with a clear inner bag, enclosed in a translu cent outer bag. The “cleanbo x” is handled using

“clean hands / dirty hands” techniques, where by the inner bag is ha ndled only by the “clean

hands” sampler. When the “cleanbox” is opened, the sampler is able to position his/her hands in

the box and pull the bag over the open ing of the box, but is still able to see the sample bottles and

# 3-2 tubing. The “cleanbox” minimizes potential at mospheric contamination during sample

collection. Figure C-1, in Appendix C, is a pictur e of a sampler working inside a “cleanbox.”

The metals sample bottles were also double-bagged. To collect the metals samples, EPA

placed the sample bottles (while still in its seal ed inner bag) into the “cleanbox” following the

protocols specified in Method 1669, also referred to as “clean hands / dirty hands” protocols.

Sampling staff filled the sample container, then cl osed the sample bottle lid and sealed the inner

bag as quickly as possible with in the “cleanbox.” The bagged sample bottles were then removed

from the “cleanbox” and placed into the outer bag following the “clean hands / dirty hands”

protocols.

3.1.1 Influent to FGD Wastewater Treatment System

The influent to FGD wastewater treatment syst em (SP-1) was collected from a sample tap

located on the piping from the secondary hydrocycl one to the equalization tank. The sample was

collected prior to the wastewater entering th e equalization tank because the plant adds lime

directly to the equali zation tank and, therefore, the sampli ng point upstream of the tank provides

the best representation of the FGD scrubber purg e from the Miami Fort FGD system. Figure 2-1

identifies the sampling location for SP-1. This samp le was collected as a grab sample because the

flow into the equalization tank is not conti nuous. In addition, due to the relatively high

concentration of suspended solids, the FGD purge was not amenable to collecting representative

split samples using composite sampling techniques.

On Day 1 only, prior to collecting the sample s at the influent to the FGD wastewater

treatment system (SP-1), the sampling team collected field blanks (SP-4) for total mercury, total

and dissolved metals, and dissolved hexavalent chromium (total and dissolved metals and

dissolved hexavalent chromium were collected in a 10-liter container and samples were pumped

into individual bottles later). See Section 5.2.3 for a description of the field blank sample

collection procedures at th e influent to the FGD wast ewater treatment system.

The sampling point was located on the pipe between the secondary hydrocyclone and

equalization tank, and was only accessible from th e top of the equalization tank. To collect the

wastewater samples at the influent to the F GD wastewater treatment system, the samplers

attached a 25-foot length of silicone tubing to the sample tap on top of the equalization tank and

had the tubing run to the ground level where the sa mples were collected. The end of the silicone

tubing was fitted with a “Y” spli tter, with two additional lengths of silicone tubing attached to

the “Y” splitter. Figure C-2, in Appendix C, is a picture of the tubing att ached to the sample tap

at the influent to the FGD wastewater treatment system. Figure C-3, in Appendix C, is a picture

of the sample collection set up at the influent to the FGD wastewater treatment system. The

samplers attached the silicone tubing to the samp le tap, opened the valve, and allowed sample to

flow through the tubing for two minutes before be ginning to fill sample containers. The samplers

did not close the valve until all samples were coll ected (except the dissolved metals samples). On

Day 2 of the sampling episode, the sampling team set up a tent to cover the samplers/samples

from rain during the sample collection.

The samplers collected the following samples using a “cleanbox,” as described in Section

3.1:

 

# Total and dissolved mercury;

# 3-3  

# Total metals by 200.8; and

 

# Total metals by 200.7.

Samplers then filled a 10-liter container with sample to be pumped off later for collection

of dissolved metals sample fractions. After all samples were collected at the sampling point for

the day, the filled 10-liter container was transported to the staging area, put on ice, and then left

untouched to allow the solids in the wastewater to settle.

The sampling team collected an aliquot of sample for field testing. Sample pH and

temperature were measured immediately at the sa mpling point using four-color pH paper, a pH

meter, and a thermometer. Table 3-3 presents the field measurement data for the influent to the

FGD wastewater treatment system.

The samplers then filled containe rs for biochemical oxygen demand (BOD 5 

# ), Group I,

Group II, and total cyanide samples directly fr om the tubing without using a “cleanbox.” See

Table 3-6 for a list of Group I and Group II analytes. BOD 5 

# , Group I, Group II, and total cyanide

samples were immediately placed on ice after sa mple collection.

The total cyanide sample was immediately preserved. Lead acetate test strips and

potassium-iodide starch test stri ps were used to measure for su lfides and oxidants, respectively.

No sulfides or oxidants were detected during th e sampling episode. The samplers then preserved

the total cyanide sample with sodium hydroxide to a pH >10 S.U. and placed it on ice.

Samples for the dissolved metals analyses we re pumped from the previously filled 10-

liter container. The pump-off station consisted of a length of Teflon® tubing attached to a length

of silicone tubing, which was threaded through an ISCO peristaltic pump. The sampling team

attached a capsule filter to th e silicone tubing, which was a s hort distance downstream of the

pump. They then attached another short length of silicone tubing to the capsule filter effluent,

which was attached to a “Y” spli tter and two lengths of silicone tubing. This set-up allowed EPA

to collect “true” split samples w ith Miami Fort’s representatives. Figure C-4, in Appendix C, is a

picture of the set-up at the pump-off station.

On Day 1 only, ERG collected field blank samples (SP-4) for dissolved metals and

dissolved hexavalent chromium by pumping from a previously filled 10-liter container. See

Section 5.2.3 for a description of the field blank sa mple collection procedures at the influent to

FGD wastewater treatment system.

After collecting the field blank samples, the sampling team placed the end of the Teflon®

tubing into the 10-liter c ontainer filled with wastewater from the influent to the FGD wastewater

treatment system. By this time, the solids in th e wastewater had been se ttling for approximately

100 minutes. Approxima tely 0.5- 2 liters 1 

# of sample were pumped through the tubing/filter to

purge the line before collecting samples.

Samplers collected the following dissolved sa mples using a “cleanbox,” as described in

Section 3.1:

1 

# During Day 1, the capsule filter became clogged, so after the field blank and first sample collection, the filter was

changed and briefly purged. On Day 2, 3, and 4, the filter /tubing was purged for less than a minute, 1 liter, and 0.5

liters respectively and there was no need to change the filter.

# 3-4  

# Dissolved metals by 200.8;

 

# Dissolved metals by 200.7; and

 

# Dissolved hexavalent chromium.

Hexavalent chromium samples were immedi ately placed on ice after sample collection.

The samples of the influent to the FGD wastew ater treatment system that were collected

represent the FGD scrubber purge from the specific unit that was pur ging at the time the samples

were collected. The following identifies which units are represented by each day of sampling:

 

# Day 1 – Unit 8;

 

# Day 2 – Unit 7;

 

# Day 3 – Unit 8; and

 

# Day 4 – Unit 7.

3.1.2 Effluent from FGD Wastewater Treatment System

The effluent from FGD wastew ater treatment system (SP-2) was collected from a tap

located on the suction side of the pump that transfers the wastewater from the effluent tank to the

ash pond. Miami Fort installed a three-way splitter on the sample tap that had three separate taps

to collect samples from the sampling point. The sample tap was located inside the FGD

wastewater treatment building (see Figure 2-1 fo r the sampling location for SP-2). Because the

sampling point was located inside, there were no wind or rain concer ns during the sample

collection.

ERG collected the effluent from FGD wastew ater treatment system composite samples

using two automatic compositors which were prog rammed to collect individual sample volumes

into two 20-liter containers. The compositors we re programmed to collect 870 milliliters (mL)

every hour during the 24-hour composite period. Following the composite period, ERG pumped

off the specific sample volumes into the individual sample containers.

ERG used one automatic compositor to collect sample volume for the metals analyses

(excluding mercury) and another automatic compos itor to collect sample volume for all classical

analytes (i.e., BOD 5 

# , Group I, and Group II, excluding cy anide). In addition to collecting

automatic composite samples for the analytes listed above, ERG collected total and dissolved

mercury grab samples every six hours during ea ch compositing period. ERG also collected one

grab sample for cyanide during each compositing period.

On Day 1 only, prior to star ting the automatic compositors at the effluent from FGD

wastewater treatment system (SP-2), the sampling team collected field blanks (SP-5) for total

and dissolved metals and dissolved hexavalent ch romium (samples were collected in a 20-liter

container and samples were pumped into indi vidual bottles later). See Section 5.2.3 for a

description of the field blank sample collection procedures at the effluent from the FGD

wastewater treatment system.

Samplers set up the compositors by attaching tw o silicone tubing sets to two of the taps

on the three-way splitter. The t ubing configuration was set up such that one end was connected

to the sample tap, and one end was threaded th rough the automatic comp ositor and connected to

the large composite container. The samplers a ttached the silicone tubing to the sample tap,

# 3-5 opened the valve, and allowed sample to flow through both sets of tubing before calibrating

either of the automatic compositors. This en sured that the flow through the tubing during

calibration would be the exp ected flow through the tubing during sample collection. The

automatic compositors were calibrate d such that they collected 870 mL 2 

# every hour, so that the

projected complete volume would be 20 liters. After calibration, the tubi ng was attached to a

vented cap on a 20-liter composite container. The sample tap was left open during the entire

sample collection time period, and the automatic compositor pulled sample as dictated by the

sampling program. Additionally, the automatic co mpositor was capable of purging the line back

through the sample tap between each individual sample aliquot.

Both 20-liter composite containers were placed into plastic trash cans, and maintained on

ice for the entire 24-hour compositing period. A plas tic bag was placed on t op of the trash cans

to minimize contamination. Figure C-5, in Appendix C, is a picture of the composite sampling

set-up at the effluent from the bioreactor system.

Immediately after setting up the compositors, ERG collected the first set of the total and

dissolved mercury grab samples. At the first gr ab sample every day, ERG collected field blanks

for total mercury samples. See Section 5.2.3 for a de scription of the field blank sample collection

procedures at the effluent from FGD wastewater treatment system.

For mercury collection, samplers shrouded one of the three taps on the three-way splitter

(the other two taps were being used by the two compositors) with a clean plastic bag by

puncturing a hole in the bottom of the bag with the end of the tap and then securing it to the tap

with a ziptie. After purging the ta p for two minutes, the samples were collected directly from the

tap into the sample bottles. Becau se total mercury and dissolved mercury samples were collected

directly from the tap, ERG was not able to collect split samples with Miami Fort’s

representatives; therefor e, duplicate samples were collected. ERG collected another set of total

and dissolved mercury samples every six hours th ereafter over the 24-h our period. The plastic

shroud was replaced for each set of mercury grab samples. After collecti ng each set of mercury

grabs, ERG filled a field test bottle and tested for pH and temperature using a calibrated pH

meter, four-colored pH paper, and a thermometer. Table 3-3 presents the field measurement data

for the effluent from FGD wastewater treatment system.

After the collection of the thir d set of mercury grabs, ERG collected a total cyanide grab

sample from the same tap on the three-way splitt er that was used for mercury sample collection.

Because total cyanide samples were collected directly from the ta p, ERG was not able to collect

split samples with Miami Fort’s representatives; th erefore, duplicate samples were collected. The

total cyanide sample was immediately preserved. Lead acetate test strips and potassium-iodide

starch test strips were used to measure for su lfides and oxidants, respectively. No sulfides or

oxidants were detected during this sampling ep isode at the effluent from FGD wastewater

2 

# The Sampling Plan called for calibrating the compositors to collect 830 mL every hou r; however, because the

pumps that transfer the wastewater from the effluent tank to the ash pond do not operate continuously, the volume of

water that could be pulled for a specific aliquot varied depending on if the pumps were operating (less volume

collected) or idle. Therefore, the automatic compositors we re calibrated while the pumps were idle and the program

was set to collect more than 830 mL (specifically 870 mL) to account for the reduced volume that would be

collected while the pumps were operating. On Day 1, the me tals carboy collected 21 liters of sample (the volume of

the classicals carboy was not noted). On Day 2, the metals and classicals carboys collected 20 and 21 liters,

respectively. On Day 3, the metals and classicals carboys collected 20 and 21.5 liters, respectively. On Day 4, the

metals and classicals carboys collected 19.5 and 20 liters, respectively.

# 3-6 treatment system. ERG samplers then preserved the total cyanide samples with sodium

hydroxide to a pH >10 S.U. a nd placed the samples on ice.

After the twenty-fourth aliquots were coll ected in the two composite containers, ERG

followed “clean hands / dirty hands” sampling tec hniques to disassemble the compositors from

the sampling set up. Closed caps were placed on th e two composite containers and the composite

containers were moved to the pump-off area wher e they remained on ice until individual sample

bottles were filled. The samplers then began setting up the compositors for the next day of

samples using new tubing sets and composite containers. The automatic compositor was

programmed to collect the same volum e on each day of sample collection.

After completing the set up for the next day of composite samples, the sampling team

transferred the wastewater coll ected in the 20-liter containe rs into the individual sample

containers at the pump-off area. For this samp ling point, ERG used a sample pump-off approach

to transfer the composite samples to the individual sample bottles. For this sample pump-off

procedure, the dissolved metals samples were collected before the total metals and classical

samples to prevent cross-contamination with in the tubing, which could lead to greater

concentrations in the dissolved metals fractions.

Samples for the dissolved and total metals analyses were pumped from one of the

previously filled 20-liter cont ainers. The pump-off station cons isted of a length of Teflon®

tubing attached to a length of silicone tubing, which was threaded throu gh an ISCO peristaltic

pump. The sampling team attached a capsule fi lter to the silicone t ubing, which was a short

distance downstream of the pump. The samplers th en attached another short length of silicone

tubing to the capsule filter effluent, which was attached to a “Y” split ter and two lengths of

silicone tubing. This set-up allowed EPA to co llect “true” split sample s with Miami Fort’s

representatives. Figure C-4, in Appendix C, is a picture of the set-up at the pump-off station.

On Day 1 only, ERG collected field blank samp les (SP-5) for total and dissolved metals

and dissolved hexavalent chromium by pumping fro m a previously filled 20-liter container. See

Section 5.2.3 for a description of the field blank sample collection proced ures at the effluent

from FGD wastewater treatment system.

After collecting the field blank samples, the sampling team placed the end of the Teflon®

tubing into one of the 20-liter composite containers filled with wastewater from the effluent from

FGD wastewater treatment system . After the tubing and filter we re purged with 1-2 liters of

sample, samplers collected the following sample s using a “cleanbox,” as described in Section

3.1:

 

# Dissolved metals by 200.8;

 

# Dissolved metals by 200.7; and

 

# Dissolved hexavalent chromium.

Hexavalent chromium samples were immedi ately placed on ice after sample collection.

After the dissolved metals had been collected, the filter was removed. Once the tubing was

purged with 1-2 liters of sample, samplers coll ected the following samples using a “cleanbox,” as

described in Section 3.1:

 

# Total metals by 200.8; and

# 3-7  

# Total metals by 200.7.

After the metal samples had been collected, the sampling team placed the end of the

Teflon® tubing into the other prev iously filled 20-liter contai ner. After the tubing was purged

with 1-2 liters of sample, samplers fille d containers for biochemical oxygen demand (BOD 5 

# ),

Group I, and Group II samples directly from the tubing without using a “cleanbox.” See Table 3-

6 for a list of Group I and Group II analytes. BOD 5 

# , Group I, and Group II samples were

immediately placed on ice af ter sample collection.

For all analytes, ERG collected QC sample s at the effluent fr om FGD wastewater

treatment system (SP-2) on Day 3 of the samp ling episode. In addition, for all analytes, ERG

collected a duplicate sample of the effluent from FGD wastewater system (SP-3) on Day 2 of the

sampling episode.

3.2 List of Analytes and Sample Preservation

Samples collected at Miami Fort were analyzed for the following pollutants:

 

# Classicals:

— Biochemical oxygen demand, 5-day (BOD 5 

# ),

— Chemical oxygen demand (COD),

— Total suspended solids (TSS),

— Total dissolved solids (TDS),

— Sulfate,

— Chloride,

— Total Kjeldahl nitrogen (TKN),

— Ammonia as nitrogen,

— Nitrate/nitrite as nitrogen,

— Total phosphorus,

— Total cyanide;

 

# Total Metals:

— 

# Aluminum, antimony, arsenic, barium, beryllium, boron, cadmium,

calcium, chromium, cobalt, copper , iron, lead, magnesium, manganese,

mercury, molybdenum, nickel, selenium, silver, sodium, thallium, tin,

titanium, vanadium, and zinc.

 

# Dissolved Metals:

— 

# Same parameters as listed for total metals, plus hexavalent chromium.

The analytes selected reflect the current understanding of coal-fired power plant air

pollution control wastewaters, in cluding contributions from coal , scrubber sorb ents, treatment

chemicals, and other sources. Table 3-4 lists the analytical methods used to determine pollutant

concentrations.

Table 3-6 lists the containers used for sample collection as well as the preservation

requirements for each sample. Table 3-7 summarizes the chemical preservation for each of the

samples that were preserved on site. The sampli ng team preserved samples in accordance with

procedures described in Section 3.4 of the Sampling Plan. Immediately following sample

# 3-8 collection, the samplers placed the BOD 5 

# , Group I, Group II, dissolved hexavalent chromium,

and total cyanide samples on ice to cool the sa mples to <6°C. The sampling team did not place

the total and dissolved metals or the total and dissolved mercury samples on ice, which comports

with the requirements of Methods 200.7, 200.8, and 1631E. All dissolved metals samples, except

for mercury, were filtered in the field. The hexavalent chromium samples were preserved in the

field, but all other metals samples were acid-pre served prior to extraction at the laboratory. The

hexavalent chromium samples were preserve d with ammonium sulfate buffer solution and

ammonium hydroxide to a pH between 9.3 and 9.5 S.U. The Group II samples were preserved

with sulfuric acid to a pH of <2 S.U. in the staging area, and the pH was confirmed with fourcolor pH strips. Each total cyanide sample was te sted for sulfides and oxidants immediately after

sample collection. Because sulfides and oxidants we re not detected at any of the sampling points

during the sampling episode, the samplers did not need to dilute the samples or add sodium

arsenite to the samples. After testing for sulfid es and oxidants, the total cyanide samples were

preserved with sodium hydroxide to a pH >10 S.U. and placed on ice.

3.3 Plant Operational Data

During the EPA sampling episode, Miami Fort plant personnel pr ovided the sampling

team with operational data for each of the gene rating units and the FGD scrubber system, as well

as operational and flow data for the FGD wastew ater treatment system. Table 3-8 presents the

unit operating characteristics, Table 3-9 presents the FGD scrubber system operating

characteristics, Table 3-10 presents informati on on the coal burned during the sampling episode,

Table 3-11 presents information on the FGD sc rubber slurry generation during the sampling

episode, and Table 3-12 presents th e FGD wastewater treatment syst em operating characteristics.

3.4 Deviations from the Sampling and Analysis Plan

The sampling episode proceeded as specified in the Sampling Plan with the exceptions

described below:

 

# Preservation of hexavalent chromium: ERG planned to preserve the hexavalent

chromium samples to a pH between 9.3 and 9.7 S.U. using an ammonium sulfate

buffer solution; however, since the amm onium sulfate buffer solution was not

achieving the desired pH, the samplers added only 100 drops of ammonium

sulfate buffer solution, followed by as mu ch ammonium hydroxide as necessary

to reach the desired pH.

 

# Influent to FGD wastewater treatm ent system samples (SP-1, Day 2): After

set up at the sampling location at the in fluent to FGD wast ewater treatment

system (SP-1), the sampling team had to wait approximately 15 minutes to collect

the sample because the plant staff switched the pumps that were transferring the

FGD scrubber purge to the equalization tank.

 

# Field test temperature measu rement (SP-2, Grab 4, Day 4): At the effluent

from FGD wastewater treatment syst em (SP-2), the field temperature

measurement taken during Grab 4 on Day 4 was only taken with the pH meter

because the thermometer was misplaced.

# 3-9  

# Collection of field test measu rements (SP-2, Grab 3, Day 2): The field test

samples taken in conjunction with the Day 2 Grab 3 samples at the effluent from

FGD wastewater treatment system (SP-2) were taken approximately 7 minutes

after the grab sample because the effluent wastewater transfer pump kicked on

immediately after the cyanide sample was taken. The water pressure was too low

to collect the field test sample while the pump was running, so the samplers

waited until the pump turned off in orde r to grab the field test sample.

 

# Collection of total mercur y (SP-2, Grab 1, Day 1): On Day 1 of sample

collection at the effluent from the FGD wastewater treatment system (SP-2), the

bottle cap for the total mercury sample was dropped, but it fell onto the bottle bag

and did not touch the ground. After the bottl e was filled, the cap was used to seal

the bottle.

 

# Filtering and purging the influent to FGD wastewater treatment system

sample (SP-1): When collecting the dissolved meta l samples at the influent to

FGD wastewater treatment system (SP-1) on Day 1, the capsule filter became

clogged, so after the field blank and first sample collection, the filter was changed

and briefly purged. On Day 2, 3, and 4, the filter/tubing was purged for less than a

minute, 1 liter, and 0.5 liters, respectivel y, and there was no need to change the

filter.

 

# Calibrating the automatic compositors at the effluent from FGD wastewater

treatment system (SP-2): The Sampling Plan called for calibrating the

compositors to collect 830 mL every hour; however, because the pumps that

transfer the wastewater from the effl uent tank to the ash pond do not operate

continuously, the volume of water that could be pulled for a specific aliquot

varied depending on if the pumps were opera ting (less volume collected) or idle.

Therefore, the automatic compositors were calibrated while the pumps were idle

and the program was set to collect more than 830 mL (specifically 870 mL) to

account for the reduced volume that would be collected while the pumps were

operating.

 

# Influent to FGD wastewater treatmen t system dissolved metals samples

pump-off (SP-1): The suspended solids content in the influent to the FGD

wastewater treatment system samples was high; therefore, the samplers allowed

the solids to settle for 100 minutes to two hours, before pumping off the dissolved

metals samples each day, instead of allo wing the solids to sett le for one hour as

the Sampling Plan suggested.

# This section summarizes the laboratory results of analyses of samples for the influent to

the FGD wastewater treatment system and the effluent from the FGD wastewater treatment

system. Section 4.1 discusses the methods used by the laboratories for th e biphasic analysis of

SP-1. Section 4.2 presents the laborat ory analytical data for the infl uent to and effluent from the

FGD wastewater treatment system.

Appendix A provides all analytical results for all samples collected at Miami Fort,

including all qualified results a nd all results that were measur ed above the method detection

limit, but below the quantita tion limit (i.e., J-values).

4.1 Measured and Calculated Results for In fluent to FGD Wastewater Treatment

System Samples

The samples of the influent to the FGD wast ewater treatment system were expected to

contain significant amounts of r eadily settleable solids, to a large degree consisting of gypsum,

unreacted limestone, and fly ash. Because of th is, EPA was concerned that there could be

analytical interferences for the metals analyses, since the acid digestion procedures used may not

be sufficiently rigorous for samples with high solid s loads. Therefore, ERG directed its contract

laboratories to separate the aque ous and solid phases of the samp le prior to conducting certain

analyses, where allowed by the analytical method and if necessary to obtain acceptable analytical

results. This biphasic approach provides EPA with measured or calculated pollutant

concentrations for the following phases of the sample:

 

# Aqueous phase;

 

# Solid phase; and

 

# Total sample.

The metals and classicals laboratory, Test America Laboratories - Denver (TestAmerica),

and the mercury laboratory, Frontier Global Scien ces (Frontier), used two different approaches

for the biphasic analysis. This section describes the approaches used by each laboratory and

presents the results of the analyses.

Metals and Classicals Analyses

TestAmerica used EPA Methods 200.7 and 200.8 to analyze the wastewater samples for

metals. Both EPA Methods 200.7 and 200.8 state, “Aqueous samples containing total suspended

solids ≥ 1% (w/v) should be extracted as a solid type sample.” [3, 4] Because EPA expected the

solids content to be greater than one percent, TestAmerica developed an approach for the

analysis of the FGD influent samples that consiste d of performing a pressure filtration to separate

the solids from the sample and analyzing the so lid and aqueous phases separately. TestAmerica

also dried the solids prior to analysis, so the so lid concentration is on a dry-weight basis. To

calculate the total sample concentration from th e solid and aqueous phase results, the laboratory

also needed to measure the original sample vol ume, solid phase weight, and filtrate volume. EPA

developed the following equation to calculate the individual metal total concentrations for the

sample.

# 4-2 Sample Solid Solid Filtrate Filtrate



# V ) Wt (C ) V (C ion Concentrat Sample Total   

 

# (4-1)

where:

C Filtrate 

# = concentration of the analyte in the aqueous phase of the sample;

V Filtrate 

# = volume of the filtrate;

C Solid 

# = concentration of the analyte in the solid phase of the sample;

Wt Solid 

# = weight of the solids in the sample; and

V Sample 

# = volume of the original sample.

TestAmerica used the same approach for the se ven classical pollutants that were analyzed

as biphasic samples: ammonia as nitrogen, chloride, sulfate, nitrate/nitrite, total cyanide, total

Kjeldahl nitrogen (TKN), and total phosphorus.

Mercury Analyses

Frontier used EPA Method 1631E to analyze the wastewater samples for mercury. EPA

Method 1631E does not contain a ny language stating how wastewat er samples with high solid

concentrations should be analyzed ; therefore, Frontier developed an approach for the analysis of

the FGD influent samples that minimized potenti al contamination to the samples. Frontier’s

approach consisted of using a centr ifuge to separate the solids from the sample and analyzing the

solid and aqueous phases se parately. Frontier did not dry the solids prior to analysis, so the solid

concentration is on a wet-weight basis. To cal culate the total sample concentration from the

solid and aqueous phase results, the laboratory also needed to measure the original sample

volume, solid phase weight, and filtrate volum e. EPA used Equation 4-1 to calculate the

individual total mercury con centrations for the sample.

Appendix Tables A-1 through A-4 present th e results of the biphasic analysis for

ammonia as nitrogen, nitrate/nitrit e, chloride, sulfate, nitrate/nitrite, total cyanide, TKN, total

phosphorus, total metals, and total mercury for each of the four days of sampling. Results are

rounded to three significant figures.

4.2 FGD Wastewater Treatment System

Table 4-1 presents the analytical results for all classical and metal analytes for the four

days of sampling at the influent to the FGD wast ewater treatment system (SP-1), as well as the

calculated 4-day average result for each analyte for the sampling point. The total metal results

presented in Table 4-1 represent the calculated total result for all analytes for which biphasic

separation was performed. Table 4-2 presents the analytical results for all classical and metal

analytes for the four days of sampling at the e ffluent from the FGD wast ewater treatment system

(SP-2).

Tables 4-1 and 4-2 include the analytical results for all anal ytes for which EPA conducted

analyses. Results are rounded to three signifi cant digits. If an analyte was not detected in a

sample above the method detection limit, the resu lt is reported as “ND” followed by the samplespecific quantitation limit in parentheses. If an analyte was measured above the method

detection limit, but below the quantitation limit, the result is reported as “NQ” followed by the

sample-specific quantitation limit in parentheses.

# 4-3 For Table 4-2 (effluent from the FGD wastew ater treatment system), a duplicate sample

was collected on Day 2 of the sampling episode. The Day 2 results presented in Table 4-2

represent the averag e of the original and the duplicate samp le results. Table 5-2 presents the

analytical results for the original and duplicat e results and the calculated relative percent

difference (RPD).

When calculating the average concentrations for the duplicate samples or for the 4-day

averages, ERG used the following methodology:

 

# If all results were above the quantitati on limit, then all results were averaged

together;

 

# If at least one result was above the quan titation limit, then 1⁄2 the quantitation limit

was used in the average calculation for all results that were less than the

quantitation limit and the result is repo rted with a less than sign (“<”);

 

# If all results were below the quantitation limit, but at least one result was above

the method detection limit (i.e., J-value), then the sample-specific quantitation

limits for all results were averaged and the result is reported as “NQ” followed by

the average of the sample-specific quantitation limits; and

 

# If all results were below the method de tection limit, then the sample-specific

quantitation limits for all results were aver aged and the result is reported as “ND”

followed by the average of the sample-specific quantitation limits.

Table 4-3 presents the 4-day average results fo r all classical analytes for the influent to

the FGD wastewater treatment system (SP-1) and the efflue nt from the FGD wastewater

treatment system (SP-2). Table 4-4 presents th e 4-day average results for all metal analytes,

including total and dissolved analyses, for the in fluent to the FGD wastewater treatment system

(SP-1) and the effluent from th e FGD wastewater treatment system (SP-2). The results presented

in this report are not paired results, meaning that the sample collection across the treatment

system was not timed to reflect the amount of time it takes the wastewater to pass through the

system.

Appendix Tables A-5 through A-13 present all the analytical results from the influent to

the FGD wastewater treatment system (SP-1), th e effluent from the FGD wastewater treatment

system (SP-2), and the duplicate of the effluentfrom the FGD wastewater treatment system (SP3) sample analyses, including J-values.

# 4-4Note: The total metals results and the results for certain classical analytes (i.e., ammonia as nitrogen, nitrate/nitrite, chloride, sulfate, nitrate/nitrite, total cyanide, TKN, totalphosphorus) represent the total result that was calculated based onthe results of the solid and aqueous phase of the samples.See Section 4.1 for more details.< - Average result includes at least one value measured belowthe quantitation limit.

# Q UALITY



# Quality assurance/quality control (QA/QC) pr ocedures applicable to the Miami Fort

sampling episode are outlined in the Quality Assurance Project Plan for the Steam Electric

Rulemaking (QAPP) [2]. This section describes the QC pr ocedures used to assess the precision

and accuracy of the analytical data presented in Section 4 and Appendix A. QC practices used

for this sampling episode include the analysis of matrix spikes, blanks, duplicate samples, and

QC standard checks.

5.1 Analytical Quality Control

ERG contracted directly with analytical labor atories for the analysis of samples collected

during this episode. ERG verified that the pe rformance of the laboratories selected was

acceptable by conducting QC checks of the analytical data. Data review chemists at ERG

prepared written data review narr atives describing any qualifications of the analytical data from

this episode. The data review narrat ives are included in Appendix B.

5.2 Field Quality Control

This subsection discusses the bottle blanks, equipment blanks, field blanks, and field

duplicate sample results. Section 3.8 of the Samp ling Plan discusses fiel d QC specifications.

5.2.1 Bottle Blanks

ERG collects bottle blanks to evaluate possibl e contamination from the sample collection

bottles. Bottle blanks were collected and analyzed for metals (EPA Method 200.8, 200.7, and

1631E) by the supplier of the precleane d bottles, Frontier Global Sciences.

Frontier Global Sciences collected the bottl e blanks for the metals sample bottles by

filling the precleaned bottle with reagent water, pres erving the sample with nitric acid to a pH <2

S.U. Frontier Global Sciences then an alyzed the samples using EPA Method 1638.

Frontier Global Sciences collected the bottl e blanks for the mercury sample bottles by

filling the precleaned bottle with reagent wa ter, preserving the sample with bromine

monochloride. Frontier Global Sciences then analyzed the samples using EPA Method 1631E.

Albion Environmental collected the bottle bl anks for the 10- and 20-liter composite

containers by filling the container with approx imately two liters of ASTM Type 1 water and

allowing it to soak for approximately 24 hours. During this period, th e laboratory shook the

container periodically and changed its orientation to expose all surfaces of the container to the

ASTM Type 1 water. Albion Environmental th en shook the 10- and 20-liter containers and

poured a representative sample into a preclean ed LDPE bottle. The blank samples were then

preserved and analyzed according to the analytical methods (i.e., EPA Method 1638).

No metals were detected in the bottle blanks , except for aluminum in two of the three 10-

liter composite containers. Aluminum was detected in the 10-L container at a concentration of

4.71 ug/L, which is well below the quantitation lim it used for the sample analyses (i.e., 200

ug/L); therefore, this contamination did not aff ect the results of the sampling episode. Appendix

# 5-15 Table A-14 presents all of the analytical results from the bottle blank analyses for the bottles

used to collect the metals and mercury samples.

5.2.2 Equipment Blanks

EPA collects equipment blanks to evaluate possible contamination from the equipment

used for sample collection. The techniques used to collect field blanks (a s described in Section

5.2.3) include the sampling equipment and ther efore would identify whether the sampling

equipment was introducing contamination. In a ddition, Frontier Global Sciences collected and

analyzed equipment blanks for metals (EPA Method 1638 and 1631E) for each type of

precleaned equipment supp lied for the episode.

Frontier Global Sciences collected the equipment blanks for the capsule filters and

fabricated tubing sets by pumping reagent wa ter through the cleaned and fully assembled

equipment sets (with the filter attached) into a cleaned bottle (an HDPE bottle for metals and a

glass bottle for mercury). The blank samples were then preserved and analyzed according to the

analytical methods (EPA Method 1638 and 1631E), as described in Section 5.2.1 for the bottle

blank samples.

No other metals were detected in the e quipment blanks, indicating that there was no

contamination from the sampling equipment. Appe ndix Table A-14 presents all of the analytical

results from the bottle blank and equipment blank analyses for all of the equipment used for the

collection of metals and mercury samples.

5.2.3 Field Blanks

The sampling team collected field blanks (SP-4 and SP-5) to evaluate possible

contamination from sampling equipment, samp ling equipment decontamination procedures,

sample collection procedures, or atmospheric contamination. EPA analyzed the field blank

samples for the total and dissolved metals, di ssolved hexavalent chromium, and total and

dissolved mercury samples 3



# .

The total mercury, total metals by 200.8, and total metals by 200.7 field blank samples

for the influent to the FGD wastewater treatm ent system (SP-4) were collected by pouring

ASTM Type 1 water through a precle aned funnel attached to the si licone tubing used for sample

collection. To prevent potential atmospheric deposition, the sampling team shrouded the blank

water and funnel with a plastic bag while pouring the blank water into the funnel and placed the

sample bottles in a “cleanbox.” Prior to filli ng the sample bottles, the tubing was purged with

approximately 1 liter of blank water. The ASTM Type 1 water flowed through the funnel, tubing,

and “Y” splitter, and was poured into the sample bottles. EPA collected the field blank samples

3 

# EPA did not collect a dissolved mercury field blank samp le because the sample filtration was performed at the

laboratory to minimize potential mercury contamination. The laboratory performed a filtration blank prior to

filtering the sample, which is assessed as the field blank fo r the dissolved mercury sample. Mercury was detected at

a concentration of 0.25 ng/L in the filtration blank perf ormed for the fourth day of samples, which includes the

influent to the FGD wastewater treatment system (Day 4), the third and fourth grab sample for the effluent from

FGD wastewater treatment syst em (Day 3), and the first and second grab samples for effluent from FGD wastewater

treatment system (Day 4). Mercury was not detected above the method detection limit (0.24 ng/L) in the filtration

blanks performed for the first, second, third, or fifth day of samples.

# 5-16 as “true” split samples with Miam i Fort’s representative, using the same procedure discussed in

the sample collection de scription (Section 3.1).

The dissolved metals by 200.8, dissolved metals by 200.7, and dissolved hexavalent

chromium field blank samples for the influent to the FGD wastew ater treatment system (SP-4)

were collected by pouring ASTM Type 1 water th rough the funnel and tubi ng and into a 10-liter

composite container. After approximately 100 minutes, the sampling team began pumping off

the ASTM Type 1 water from the 10-liter composite container. Prior to filling the sample bottles,

the tubing and filter were purged with 750 mL of bl ank water. The sample bottles were placed in

a “cleanbox” and the ASTM Type 1 water was pump ed through the tubing, capsule filter, and

“Y” splitter, and into the sample bottles. EPA co llected the field blank samples as “true” split

samples with Miami Fort’s representative, using the same procedure discussed in the sample

collection descripti on (Section 3.1).

The total mercury field blank sample for th e effluent from FGD wastewater treatment

system (SP-5) was collected by shrouding one of th e three taps on the sample tap splitter with a

clear plastic bag. Before purging the sample tap, ASTM Type 1 wa ter was poured directly into

the sample bottles under the clear plastic bag.

The total and dissolved metals by 200.7 and metals by 200.8 field blank samples for the

effluent from FGD wastewater treatment system (SP-5) were collected by filling a 20-liter

composite container with ASTM Ty pe 1 water. The same T-splitter tubing used to fill the metals

composite container was used with a pump to f ill the field blank composite container. Prior to

attaching one end of the tubing to the sample tap, it was placed directly into the container

holding ASTM Type 1 water. The other end of th e tubing was attached to the vented cap on top

of the 20-liter field blank composite containe r. After enough volume was pumped into the 20-

liter field blank composite contai ner, the vented cap was repla ced with a closed cap and the

container was placed on ice in a covered plasti c trash can. The vented cap used for the field

blank collection was the same cap that was late r used for the metals composite container.

After 24 hours, the ASTM Type 1 water in the field blank composite container was

pumped off into the individual sample bottles. The sample bottles were placed in a “cleanbox”

and the ASTM Type 1 water was pumped throug h the tubing and “Y” splitter, and into the

sample bottles. EPA collected the field blank samp les as “true” split samples with Miami Fort’s

representative, using the same procedure discusse d in the sample collect ion description (Section

3.1). Prior to filling the sample bottles, the tubing was purged w ith approximately one liter of

ASTM Type 1 water. First the samplers collec ted the total metals by 200.8 and total metals by

200.7 field blank samples. Then the sampling team attached a filter to the tubing set and purged

the tubing with approximately 0.75 liter of ASTM T ype 1 water. The samplers then collected the

dissolved metals by 200.8, dissolved metals by 200.7, and dissolved hexavalent chromium field

blank samples.

Table 5-1 presents the field blank analyt ical results for SP-4 and SP-5. Only those

analytes that were detected in the field blank samples at levels above the quantitation limit are

included in the table. Results are rounded to three significant digits . Appendix Tables A-15

through A-19 present all the analytical results for the field blanks from each of the sampling

points, including all qualified results and all results that were measured above the method

detection limit, but below the quantitation limit (i.e., J-values).

# 5-17 5.2.4 Field Duplicates

The sampling team collected field duplicate samples to assess the sampling measurement

precision for the episode. Field dupl icate samples are separate samp les collected from the same

location as the original sample. The duplicate is filled immediately after the original sample and

is stored and analyzed independently. The RPD be tween the two sample results is examined to

determine the precision of the data. EPA used the following equation to calculate the RPD for

the duplicate sample results.

where:

S = concentration of the analyte from original sample analysis;

D = concentration of the analyte from the duplicate sample analysis; and

RPD = relative percent difference between the original and duplicate sample

result.

During this sampling episode, EPA collected duplicate samples for the effluent from

FGD wastewater treatment system (SP-3) durin g Day 2 of the sampling episode. The duplicate

samples were analyzed for all analytes. Table 5-2 presents analytical results and the RPD for SP3. Results are rounded to three significant digits . Appendix Tables A-10 a nd A-13 present all the

analytical results for the efflue nt from FGD wastewater treatmen t system (SP-2) Day 2 and the
