# 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 June 6 - 11, 2010, at Duke Energy Carolinas’ Belews Creek Steam Station (Belews Creek),

located in Belews Creek, Nort h Carolina (Sampling Episode 6558). The focus of Episode 6558

was to characterize the purge stream entering th e flue gas desulfuriza tion (FGD) wastewater

treatment system and the influent to and efflue nt from the FGD bioreactor treatment system. The

influent to the bioreactor syst em also represents 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 flue gas desu lfurization (FGD) systems present at coal-fired

power plants. Based on these findings, EPA ha s focused the sampling program on characterizing

the untreated FGD wastewaters a nd effluent quality from tec hnologies 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.

Belews Creek 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 two generating units;

 

# The plant operates limestone forced oxidation wet FGD systems on both units;

 

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

includes the following steps:

— Equalization,

— pH adjustment (lime addition),

— Ferric chloride addition,

— Polymer addition,

— Clarification,

— Filtration,

— Biological treatment (nitrogen and metals), and

 

# The plant operates selective catalytic reduction (SCR) systems on both units; 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 Belews Creek on March 12, 2008 as part of the detailed study. EPA

also collected samples from the FGD wastewater treatment system at Belews Creek in October

2008 as part of the detailed study. Data obtained from the October 2008 sampling episode can be

found in the Final Sampling Episode Report Duke En ergy Carolinas’ Belews Creek Steam

Station (DCN 06197). The information collected during the pre-sampling site visit and during the

October 2008 sampling episode was used to create Sampling Plan, Duke Energy Carolinas’

Belews Creek Steam Station (Sampling Plan) [1], which describes the sample collection

procedures used during the sampling episode.

On Sunday, June 6, 2010, EPA arrived at Belews Creek 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 (June 7 – 11, 2010). The following personnel participated in EPA’s

sample collection activities:

 

# Ron Jordan, EPA/EAD;

 

# Jezebele Alicea, EPA/EAD;

 

# TJ Finseth, ERG;

 

# Elizabeth Sabol, ERG;

 

# Becky Schwantes, ERG;

 

# Kim Wagoner, 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 Belews Creek’s representative and

collected samples on be half of the plant.

# 2-1 2. F ACILITY 

# O VERVIEW



# Belews Creek operates two steam electric units and each has a coal-f ired boiler. Belews

Creek burns approximately 19,000 tons of eastern bituminous coal per day. Units 1 and 2, which

came on line in 1974 and 1975, respectively, each have a capacity of 1,200 megawatts (MW).

The Belews Creek plant and supporting facilitie s are located on approximately 700 acres in

Belews Creek, NC, adjacent to Belews Lake. Th e plant owns approximately 7,000 acres adjacent

to Belews Lake.

In 2008, Belews Creek retrofitted both units with wet FGD scrubber systems to control

the sulfur dioxide (SO 2 

# ) releases from the plant. The Un it 1 FGD system was installed in

February 2008, and the Unit 2 FGD system was installed in May 2008. The wet FGD scrubbers

are designed to remove more than 95 percent of SO 2 

# from the flue gas. With the addition of the

FGD scrubber systems, Belews Creek also instal led an FGD wastewater treatment system to

control the discharges of the wastewater gene rated during the operation of the FGD scrubbers.

Sections 2.1 and 2.2 further discuss the F GD scrubber systems and the FGD wastewater

treatment system, respectively.

Belews Creek retrofitted Units 1 and 2 w ith SCR systems in August 2003 and February

2004, respectively, to control nitrogen oxide (NO

x 

# ) releases from the plant. Initially, Belews

Creek was only operating the SCRs during ozon e season, May through September; however, in

January 2007, Belews Creek began operating the SCRs year-round. Belews Creek personnel

stated that the plant plans to continue operati ng the SCRs year-round into the foreseeable future.

The electrostatic precipitators (ESPs) at Belews Creek are particulate control devices that

are designed to remove 99.8 percent of the fly as h and other particulates from the flue gas.

Belews Creek utilizes ESPs to remove the fly ash from both units. The fly ash and other

particulates are collected in hoppe rs and typically are pneumatically transferred to fly ash silos.

However, Belews Creek also has the capability of handling the fly ash wet by sluicing the fly ash

in the hoppers and transferring the fly ash sluice water to the ash basin.

Units 1 and 2 have the following configuration:

 

# Boiler;

 

# Air preheater;

 

# SCR system;

 

# ESP; and

 

# FGD scrubber system.

2.1 FGD Scrubber System

Belews Creek operates a wet FGD scrubber sy stem on both Units 1 and 2, downstream of

the ESP, to control the emission of sulfur dioxide from the unit. The plant uses limestone slurry

as the sorbent for sulfur dioxide absorption. Limestone and service water are fed to on-site ball

mills, which pulverize the limestone to create the slurry. From the ball mills, the slurry is

transferred to hydrocyclones to collect limestone particles that are too la rge for use in the FGD

system. The underflow from the hydrocyclones is tr ansferred to the reject tank and then sent

# 2-2 back to the ball mill for additional processing. The overflow from the hydrocyclones, which is

approximately 27 to 30 percent solids (by weight), is transferred to the reagent tank for storage

and then used as fresh limestone slurry in the absorber.

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

pumps send the slurry to the vari ous levels of the FGD scrubber (t ypically three of four spray

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

scrubber vessel through spray nozzles. As the sl urry 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 continue to flow downward in the scr ubber until they reach the reaction tank. Belews

Creek bubbles air through th e reaction tank to oxidi ze the calcium sulfite to calcium sulfate (i.e.,

gypsum).

Belews Creek intermittently blows down th e gypsum slurry from the reaction tank to

maintain the solids concentration in the sc rubbers around 15 percent solids. The chlorides

concentration in the scrubbers is maintained between 8,000 and 10,000 parts per million (ppm),

with a design maximum chlorides concentra tion of 12,000 ppm. Belews Creek transfers the

blowdown from the scrubber to the gypsum dewatering operations.

The gypsum slurry is pumped to the prim ary hydrocyclones where the solid gypsum is

separated from the water by centrifugal force. The solid gypsum is forced outward to the walls of

the hydrocyclones and falls downward, while the wa ter exits the top of the hydrocyclones. The

gypsum from the primary hydrocyclones is transf erred to the filter feed tank, which is then

transferred to the vacuum filter belts. Th e overflow from the primary hydrocyclones is

transferred to a holding tank and then pumped to the secondary hydrocyclones. The underflow

from the secondary hydrocyclones is returned to th e scrubber or sent to the filter feed tank. The

overflow from the secondary hydrocyclones is se nt to the purge tank and then pumped to the

FGD wastewater treatment system.

Belews Creek washes the gypsum sent to the v acuum filter belts with service water, as it

is poured onto the belts. The vacuum filter be lts dry the gypsum to a moisture content of

approximately 10 percent. Belews Creek transf ers the dry gypsum to an uncovered gypsum

storage area and then trucks the gypsum to a wallboard manufacturer in Mount Holly, North

Carolina, approximately 105 mile s from the plant. Belews Creek generates approximately

500,000 tons of gypsum per year; however, plant pe rsonnel stated that th e gypsum production is

dependent on the coal being burned and sulfur content of the coal.

2.2 FGD Wastewater Treatment System

The FGD wastewater treatment system is de signed to receive intermittent transfers of

FGD wastewater from the purge tank, which contains secondary hydrocyclone overflow, at a

flow rate varying from 350 to 600 gallons per minute (gpm) for approximately 18 hours per day,

with a total daily flow rate of approximately 489,000 gallons per day (gpd). According to Belews

Creek personnel, the flow rate to the equali zation tank varies dependi ng on whether one or both

of the scrubbers are purging.

# 2-3 The plant operates the FGD wastewater trea tment system 24 hours per day. Belews Creek

installed the wastewater treatment system to treat the FGD scrubbe r purge wastewater to meet its

permit limits, which include limits for total suspended solids (TSS) and selenium. The Belews

Creek FGD wastewater treatment system c ontains the following treatment operations:

 

# Physical/Chemical Separation;

— Equalization,

— pH adjustment (lime addition),

— Ferric chloride addition,

— Polymer addition,

— Clarification,

— Filtration; and

 

# Biological Reactors;

— Cooling (heat extraction),

— Nutrient addition,

— First-stage biol ogical reaction,

— Nutrient addition, and

— Second-stage biolog ical reaction.

Figures 2-1 and 2-2, located at the end of this section, present proces s flow diagrams of

the FGD wastewater treatment system, as well as the sampling locations from EPA’s sampling

episode. Figure 2-1 is a simplified diagram of the FGD wastewater trea tment system, showing

different portions of the system. Figure 2-2 is a diagram of the chemical precipitation and

biological reactor po rtions of the treatment system.

The secondary hydrocyclone overflow from the scrubbers is transfe rred to the purge tank

and then sent to the equalization tank at the start of the wastew ater treatment system. During the

sampling episode, the FGD influent wastewater was found to contai n less than 0.5 percent solids,

had a pH between 6 and 7 S.U., and a temperatur e between 40 and 50 °C. The equalization tank

also receives water from the filtrate sump (which includes filter press filtrate), gravity filter

backwash reject, backflush waste from the biol ogical treatment system, and off-specification

biological treatment effluent.

2.2.1 Physical/Chemical Separation

From the equalization tank, the wastewater enters three reac tion tanks in series: reaction

tank 1, in which lime is added to increase the pH to between 8.5 and 9.2 S.U. (target 8.8 S.U.);

reaction tank 2, formerly used for organosulfide addition, but which is now used to provide

additional mixing; and reaction ta nk 3, in which ferric chloride is added. From reaction tank 3,

the wastewater flows to a mix chambe r where polymer (Nalco 71307) is added.

From the mix chamber, the wastewater flow sp lits and enters two clarifiers in parallel.

Each of the clarifiers is capab le of handling 100 percent of the waste stream capacity. Typically

both clarifiers are in operation. However, during the scheduled sampling event one clarifier was

out of service for preventative maintenance. The clarifiers are solids contact clarifiers that

contain a sludge bed that facilita tes removal of the solids in the wa stewater. Hydrochloric acid is

added to the wastewater at a poi nt between the clarifiers and the sand filters to adjust the pH

# 2-4 prior to the biological treatment system. The target pH after hydrochloric acid addition is 6.8

S.U. After the hydrochloric acid addition, the over flow from the two clarif iers is split and sent

through three sand filters in paralle l. Each of the sand filters can handle 75 percent of the waste

stream capacity. The target maximum TSS level fo r the sand filter effluent is 50 ppm; however,

the plant tries to achieve an effluent TSS c oncentration below 20 ppm. The sand filters are

continuous backwash gravity filter s. The filter backwash is sent to a sump, and then transferred

to the equalization tank.

The sludge from the clarifiers is transfe rred to a sludge storage tank. A portion of the

clarifier sludge is recycled fr om the sludge storage tank to reac tion tank 1, while the majority is

pumped to a filter press for dewatering. Belews Creek achieves a solids concentration of 15

percent in the sludge tank. The filter press cake is transferred to the fly ash landfill and the

filtrate is sent to the filtrate sump. Each f ilter press operation produces an average of 28,000 lbs

of filter cake. Belews Creek performs approximately 10 filter press operations per week.

2.2.2 Biological Reactors

In the bioreactor portion of th e treatment system, Belews Cree k treats the wastewater in

two stages. Each stage contains eight bioreactor cells, which are operated in para llel. Each cell

contains an activated carbon bed. Within the ac tivated carbon bed, speci alized microbes fill the

voided areas and reduce the nitrogen and metals, specifically selenium, in the wastewater. The

microbes selected for the bioreact or system have the ability to reduce selenium to its elemental

form, while other metals are precipitated as su lfide complexes. The wastewater from the sand

filters is transferred to a holding tank prior to entering a heat exchanger to reduce the temperature

from approximately 110 o 

# F to 95 o 

# F. As the wastewater flows from the heat exchanger to the first

stage of bioreactor cells, Belews Creek adds nutri ents (molasses-based), which provide a source

of carbon to feed the bacteria. Th e wastewater is divided evenly among the eight first-stage cells.

The flow to each cell is sent to 16 distribution pi pes to create an even di stribution of flow into

the top of the cell. The water le vel in the cells is approximately three feet above the activated

carbon bed.

Belews Creek operates the biore actors to achieve a negative oxidation reduction potential

(ORP) within the system, which provides the optimum environment to reduce selenium to its

elemental form. This ORP is controlled by the amount of nutrient that is fed to the system. The

plant also controls the pH in the bioreactor cells to between 6.0 and 9.0 S.U. because extreme

high or low pH levels could a ffect the performance of the microbes and potentially allow for

nondesirable microbe s to propagate.

The effluent from all eight of the first-stage bi oreactor cells is combined in the first-stage

effluent storage area. The wastewater is then transferred to the second- stage bioreactor cells,

which are operated in parallel. Nutrients are adde d to the wastewater as feed for the microbes as

the wastewater is transferred. As in the first stage, the wastew ater is divided evenly among the

eight second-stage cells and each cell has 16 distri butor pipes to evenly distribute the flow into

the cell.

Occasionally the bioreactor ce lls need to be backflushed to remove accumulated solids.

The plant pumps the effluent from the first-st age bioreactor cells b ackwards through each cell

# 2-5 and it overflows into a spillover chamber. The plant then returns the backwash overflow to the

equalization tank at the start of th e FGD wastewater treatment system.

Because the first-stage bioreac tor cells denitrify the waste stream, they produce nitrogen

and carbon dioxide gas. To remove the gas from the cells, the plant oc casionally performs a

degassing operation where water is sent backward s through the cells, like a backflush, but the

flush is only long enough for the gas to “burp” out of the system. The second-stage bioreactor

cells are primarily anoxic and do not produce as much gas as the first-stage cells, requiring less

frequent degassing than the first-stage cells.

From the second stage of the biological treatm ent system, wastewater is transferred to

two wetland supply tanks, which is then transferre d directly to the ash ba sin. According to plant

personnel, the treated FGD wastew ater, excluding cooling water, represents approximately seven

percent of the total flow discha rge from the ash basin to the Da n River, via NPDES Outfall 003.

2.2.3 Sampling Points

Figure 2-2 shows the sampling points for the Belews Creek sampling episode; they are

summarized below:

 

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

downstream of the purge tank and upstr eam of the equalization tank (i.e., the

sample was collected prior to any chem ical addition or mixing with recycle

streams);

 

# An in-process sample of the influent to the bioreactor system, downstream of the

sand filters and the holding tank and upstream of the heat exchanger; and



point to allow for split sample collection. EPA co llected all samples (other than mercury and

cyanide) at all sampling points as “true” splits (i.e., samples 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 Belews Creek’s representative collected duplicate

samples, with one filling the bot tle immediately 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

# 3-2 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

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 wastewater piping downstream of the purge tank and upstream of the equalization

tank. Figure 2-2 identifies the sampling location for SP-1. This sample was collected as a grab

sample because, according to plant representatives, the wastewater characteristics of the purge to

the wastewater treatment system are fairly cons istent during the purge. In addition, due to the

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

representative split samples usi ng composite sampling techniques.

The sampling point was located outside, near the equalization tank. There was no rain

during the sample collection.

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-6) for total mercury, total

and dissolved metals, and dissolved hexavalent chromium. See Section 5 .2.3 for a description of

the field blank sample collection procedures at the influent to the FGD wastewater treatment

system.

To collect the wastewater samples at the influent to the FGD wastewater treatment

system, the samplers attached a 10-foot length of silicone tubing to the sample tap on the

wastewater piping. The end of th e silicone tubing was fitted w ith a “Y” splitter, with two

additional lengths of silicone tubi ng attached to the “Y” splitter. Figure C-2, in Appendix C, is a

picture of the tubing attached to the sample tap at the influent to the FGD wastewater treatment

system. The samplers attached the silicone tubi ng to the sample tap, opened the valve, and

allowed sample to flow through the tubing for two minutes before beginning to fill sample

containers. The samplers did not close the valv e until all samples were collected (except the

dissolved metals samples).

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 sampling point using four-color pH paper 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 with Belews Cree k’s representatives. Figure C-3, in Appendix C,

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

The sampling team placed the end of the Teflon® tubing into the 10-lit er container filled

with wastewater from the influent to the FGD wastewater treatment system. By this time, the

solids in the wastewater had b een settling for approximately 70 minutes. Approximately 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 become clogged, so after the field blank was collected, the tubing/filter was purged

with only 0.5 liters. After the collection of the first sample (dissolved metals 200.8), the filter was changed. The

tubing/filter was purged for another 0.5 liters and the remaining two samples were collected. On day 2, the

tubing/filter was purged for 1 litter. After the collection of th e first sample (dissolved metals by 200.8) the filter was

replaced. The tubing/filter was purged briefly and the remaining two samples were collected. On day 3 and 4, the

filter/tubing was purged for 1.5 and 2.0 litters respec tively 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.

3.1.2 Influent to Bioreactor System

The influent to the bioreactor system (SP-2) was collected downstream of the sand filters

after the wastewater from the th ree filters is commingled. This sample tap is located downstream

of the holding tank and upstream of the heat exchanger. Belews Creek installed a three-way

splitter on the sample tap, which had three separa te taps to collect samples from the sampling

point. The sample tap was located inside the F GD wastewater treatment building (see Figure 2-2

for the sampling location for SP-2). At the time th at sampling occurred, one of the clarifiers was

out of service. This did not affect normal pl ant operations because Belews Creek has never

operated more than one clarifier at a time. Becau se the sampling point was located inside, there

were no wind or rain concerns during the sample collection.

ERG collected the influent from the biorea ctor system composite samples using two

automatic compositors which were programmed to collect individual samp le volumes into two

20-liter containers. The compositors were progr ammed to collect 830 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, ERG collected field blank samp les (SP-7) for hexavalent chromium, total

and dissolved metals by 200.7, and total and di ssolved metals by 200.8. See Section 5.2.3 for a

description of the field blank sa mple collection procedures at th e influent to the bioreactor

system.

Samplers set up the compositors by attaching tw o T-splitter tubing sets to two of the taps

on the three-way splitter. The T-splitter tubing set consisted of three silicone tubes attached to a

T-splitter. The tubing configura tion was set up such that one e nd was connected to the sample

tap, one end was threaded through the automa tic compositor and connected to the large

composite container, and one end was placed next to a sump/drain near the sampling point. The

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

flow through both sets of tubing before calibrati ng either of the automatic compositors. This

ensured that the flow through the tubing during calibration would be the expected flow through

the tubing during sample collection. The automatic compositors were calibrated such that they

collected 830 mL every hour, so that the project ed complete volume would be 20 liters. After

calibration, the tubing was attached to a vented cap on a 20-liter composite container. The

# 3-5 sample tap was left open during the entire sample collection time period a nd flowed directly to

the sump/drain. The automatic compositor pulled sa mple from the flowing stream as dictated by

the sampling program and was capable of purging th e line back to the flowing stream 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-4, in Appendix C, is a picture of the composite sampling

set-up at the influent to 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 influent to the bioreactor 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 pur ging the tap 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 Belews Creek’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 four-colored pH

paper and a thermometer. ERG had planned on us ing a pH meter to test the pH; however, the

sampling team could not get the pH meter to ca librate properly. Table 3-3 presents the field

measurement data for the influe nt to the bioreactor 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 Belews Creek’s representative s; therefore, duplicate samples were collected.

The total cyanide sample was immediately preserved. Lead acetate test strips and potassiumiodide starch test strips were used to measure for sulfides and oxidants, respectively. No sulfides

or oxidants were detected during the sampling episode at the influe nt to the bioreactor system.

ERG samplers then preserved the total cyanide sa mples with sodium hydroxide to a pH >10 S.U.

and 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 the two composite containers and the

composite containers were moved to the pump-off area where 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.

# 3-6 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. They then attached another short length of silicone tubing to

the capsule filter effluent, which was attached to a “Y” splitter and two lengths of silicone

tubing. This set-up allowed EPA to collect “true” split samples w ith Belews Creek’s

representative. Figure C-3, in Appendix C, is a picture of the set-up at the pump-off station.

On Day 1 only, prior to collec ting any samples of the influent to the bioreactor system,

the samplers collected a field blank sample (SP- 7) for dissolved and total metals. See Section

5.2.3 for a description of the dissolved and total metals field blank sample collection at the

influent to the bioreactor 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 influent to

the bioreactor system. After the tubing and filter were purged with 1-2 liters of sample, samplers

collected the following samples using a “cl eanbox,” as described in Section 3.1:

 

# Dissolved metals by 200.8;

 

# Dissolved metals by 200.7; and

 

# Dissolved hexavalent chromium.

Hexavalent chromium samples were immediat ely 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

 

# 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 pr eviously filled 20-liter cont ainer. Once 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.

# 3-7 For all analytes, ERG collected QC samples at the influent to the bi oreactor system (SP2) on Day 4 of the sampling episode. In additi on, for all analytes, ERG collected a duplicate

sample of the influent from bioreactor system (SP-4) on Day 3 of the sampling episode.

3.1.3 Effluent from Bioreactor System

The effluent from bioreactor system (SP-3) was collected downstream of the secondstage effluent storage tank from the second-stage bioreactor cells. Belews Creek installed a threeway splitter on the sample tap that had three separate taps to collect samples from the sampling

point. The sample tap was located inside the F GD wastewater treatment building (see Figure 2-2

for the sampling location for SP-3). Because the sampling point was located inside, there were

no wind or rain concerns during the sample collection.

ERG collected the effluent from the biorea ctor system composite samples using two

automatic compositors which were programmed to collect individual samp le volumes into two

20-liter containers. The compositors were progr ammed to collect 830 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, ERG collected field blank samp les (SP-8) for hexavalent chromium, total

and dissolved metals by 200.7, and total and di ssolved metals by 200.8. See Section 5.2.3 for a

description of the field blank sa mple collection procedures at th e effluent from the bioreactor

system.

Samplers set up the compositors by attaching tw o T-splitter tubing sets to two of the taps

on the three-way splitter. The T-splitter tubing set consisted of three silicone tubes attached to a

T-splitter. The tubing configura tion was set up such that one e nd was connected to the sample

tap, one end was threaded through the automatic compositor, and connected to the large

composite container, and one end was placed next to a sump/drain near the sampling point. The

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

flow through both sets of tubing before calibrati ng either of the automatic compositors. This

ensured that the flow through the tubing during calibration would be the expected flow through

the tubing during sample collection. The automatic compositors were calibrated such that they

collected 830 mL every hour, so that the project ed complete volume would be 20 liters. After

calibration, the tubing 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 a nd flowed directly to

the sump/drain. The automatic compositor pulled sa mple from the flowing stream as dictated by

the sampling program and was capable of purging th e line back to the flowing stream between

each individual sample aliquot.

# 3-8 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 Appendi x 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 fr om the bioreactor 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 Belews Creek’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 four-colored pH

paper and a thermometer. ERG had planned on us ing a pH meter to test the pH; however, the

sampling team could not get the pH meter to ca librate properly. Table 3-3 presents the field

measurement data for the effluent from the bioreactor 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 Belews Creek’s representative s; therefore, duplicate samples were collected.

The total cyanide sample was immediately preserved. Lead acetate test strips and potassiumiodide starch test strips were used to measure for sulfides and oxidants, respectively. No sulfides

or oxidants were detected duri ng this sampling episode at the effluent from the bioreactor

system. ERG samplers then preserved the total cyanide samples with sodium hydroxide to a pH

>10 S.U. and 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 the two composite containers and the

composite containers were moved to the pump-off area where 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

# 3-9 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. They then attached another short length of silicone tubing to

the capsule filter effluent, which was attached to a “Y” splitter and two lengths of silicone

tubing. This set-up allowed EPA to collect “true” split samples w ith Belews Creek’s

representatives. Figure C-3, in Appendix C, is a picture of the set-up at the pump-off station.

On Day 1 only, prior to collec ting any samples of the effluent from the bioreactor system,

the samplers collected a field blank sample (SP- 8) for dissolved and total metals. See Section

5.2.3 for a description of the dissolved metals fiel d blank sample collection at the effluent from

the bioreactor 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

the bioreactor system. After the tubing and filter were purged with 1-2 liters of sample, samplers

collected the following samples using a “cl eanbox,” 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

 

# 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 samples at the effluent from th e bioreactor system

(SP-3) on Day 3 of the sampling episode. In add ition, for all analytes, ER G collected a duplicate

sample of the effluent from bioreactor syst em (SP-5) on Day 2 of the sampling episode.

3.2 List of Analytes and Sample Preservation

Samples collected at Belews Creek were analyzed for the following pollutants:

# 3-10  

# 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 3-5 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

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 preserved w ith ammonium sulfate buffer solution to a pH

between 9.3 and 9.5 S.U., although for several of the samples preservation was discontinued

before this target pH was reached because the sample bottle became too full and additional

preservative could not be adde d. See Section 3.4 for more details. 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 four-color pH strips. E ach total cyanide sample was tested for sulfides and oxidants

immediately after sample collection. Because sulf ides and oxidants were 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 te sting for sulfides and oxi dants, the total cyanide

samples were preserved with sodium hydroxi de to a pH >10 S.U. and placed on ice.

# 3-11 3.3 Plant Operational Data

During the EPA sampling episode, Belews Cr eek 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 Routine Hexavalent Chromium. ERG planned to preserve the

routine hexavalent chromium samples to a pH between 9.3 and 9.7 S.U. using an

ammonium sulfate buffer solution; howe ver, for several of the samples,

preservation was discontinued because the sample bottle became too full and

additional preservative could not be added to the sample bottle. All samples at

least reached a pH of 8.5 S.U. See Tabl e 3-7 for a list of affected samples.

 

# pH field test measurements: The sampling team was unabl e to calibrate the pH

meter properly; therefore, only four-color pH strips were used to measure the pH

of the samples duri ng the field tests.

 

# Field blank hexavalent chromium sample at SP-1: Because Belews Creek’s

representative collected fewer field bla nk sample volume at SP-1, they collected

EPA’s hexavalent chromium field blank sample in their clean box while ERG was

collecting the dissolved metals by 200.7 field blank sample volume.

 

# Total mercury grab sample at SP-3 (Day 1): On day 1 of sample collection at

the effluent from the bioreactor (SP-3), gr ab one of the four total mercury grab

sample bottles was filled only three-quarters of the way full. The samplers noted

this in the traffic report that was sent with the samples to the laboratory.

 

# Collection of total metals samples at SP-2 (Day 2): On day 2 of sample

collection at the influent to the biorea ctor system (SP-2), the sampling team

dropped the end of the tubing set used to fill the sample bottles at the pump-off

area after the collect ion of the dissolved hexavalent chromium and before the

collection of total metals samples. The end of the tubing touched the ground,

therefore, the samplers pur ged the tubing with 1 liter of sample while Belews

Creek’s representatives used their end of the pump-off tubing to rinse the outside

 

# Collection of dissolved mercury samples at SP-2 (Day 3): On day 3 of sample

collection at the influent to the biorea ctor system (SP-2), the sampling team

# 3-12 dropped the outer bag on the floor and imme diately picked it up. The contents of

the sample and the inner bag were not aff ected. The outer bag was still used to

contain the inner bag and bottl e after sample collection.

 

# Classicals compositor set up at SP-2 (Day 4): On day 4 of sample collection at

the influent to the bioreactor system ( SP-2), the plastic bag covering one of the

ends of the T-splitter tubing set was dropped on the ground. The sampling team

used a new plastic bag to re-cover the end of the tubing befo re proceeding with

the sample set up.

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

the FGD wastewater treatment system and the in fluent to and effluent from the bioreactor

system.

Appendix A provides all analytical results fo r all samples collected at Belews Creek,

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).

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 analyt e for the sampling point. Tables 4-2 and 4-3

present the analytical results for all classical and metal analytes fo r the four days of sampling at

the influent to the bioreactor system (SP-2) and the effluent from the bi oreactor system (SP-3),

respectively.

Tables 4-1 through 4-3 include the analytical results for all analytes for which EPA

conducted analyses. Results are rounded to thre e significant digits. If an analyte was not

detected in a sample above the method detection limit, the result is reported as “ND” followed by

the sample-specific quantitation limit in parenthe ses. 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.

For Table 4-2 (influent to the bioreactor system), a duplicate sample was collected on

Day 3 of the sampling episode. The Day 3 result s presented in Table 4-2 represent the average

of the original and the duplicate sample results. Table 5-2 presents the analytical results for the

original and duplicate results and the calculated re lative percent difference (RPD). For Table 4-3

(effluent from the bioreactor system), a duplicat e sample was collected on Day 2 of the sampling

episode. The Day 2 results presented in Table 4- 3 represent the average of the original and the

duplicate sample results. Table 5-3 presents the analytical results for the original and duplicate

results and the calculated 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

# 4-2  

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

the FGD wastewater treatment system (SP-1), the influent to the bioreact or system (SP-2), and

the effluent from the bioreactor system (SP-3). Table 4-5 presen ts the 4-day average results for

all metal analytes, including total and dissolved an alyses, for the influent to the FGD wastewater

treatment system (SP-1), the influent to the bior eactor system (SP-2), and the effluent from the

bioreactor system (SP-3). The re sults 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-1 through A-14 present all the analytical results from the influent to

the FGD wastewater treatment system (SP-1), the influent to the bioreact or system (SP-2), the

effluent from the bioreactor syst em (SP-3), the duplicate of the in fluent to the bioreactor system

(SP-4), and the duplicate of the effluent from th e bioreactor system ( SP-5) sample analyses,

including J-values.

[QUESTION FOR BELEWS CREEK: Several mercur y results appear inconsistent with

self-monitoring data Duke Energy has provided for Belews Creek. Please describe any unusual

conditions that were occurring with the FGD system or FGD wastewater tr eatment system at the

time of sampling, or that may have occurred in the preceding days that may have affected

sampling results. Please provide a ll total and dissolved arsenic, mercury, and selenium data for

the split samples collected by Duke Energy/UWAG (on behalf of Duke Energy), for each day

and sample point.]

# Q UALITY



# Quality assurance/quality control (QA/QC) pr ocedures applicable to the Belews Creek

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 precleaned LDPE sample 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 bl anks, except for aluminum in the 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 limit us ed for the sample analyses (i.e., 200 ug/L);

therefore, this contamination di d not affect the resu lts of the sampling episode. Appendix Table

# 5-2 A-15 presents all of the analytical results from the bottle blank an alyses 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-15 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-6, SP-7, and SP-8) 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 and total and dissolved mercury samples 2



# .

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-6) 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,

2 

# 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 0.77 ng/L in the filtration blank perf ormed for the second day of samples, which includes the

influent to the FGD wastewater treatment system (day 2), the third and fourth grab samples for the influent to the

bioreactor system (Day 1), the third and fourth grab sample for the effluent fr om the bioreactor system (Day 1), the

first and second grab samples for influent to the bioreactor system (Day 2), the first and second grab samples for the

effluent from the bioreactor system (D ay 2), and the first and second grab samples for the duplicate of the FGD

effluent from the bioreactor system. Mercury was not detected above the method detection limit (0.24 ng/L) in the

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

# 5-3 and “Y” splitter, and was poured into the sample bottles. EPA collected the field blank samples

as “true” split samples with Belews Creek’s repr esentative, using the same procedure discussed

in the sample collection description (Section 3.1).

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

chromium field blank samples for the influent to the FGD wastew ater treatment system (SP-6)

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

composite container. After around 70 minutes, the sampling team began pumping off the ASTM

Type 1 water from the 10-liter co mposite container. Prior to fill ing the sample bottles, the tubing

was purged for around 40 seconds. The sample bottles were placed in a “cleanbox” and the

ASTM Type 1 water was pumped through the tubing, capsule filter, and “Y” splitter, and into the

sample bottles. EPA collected the field blank sa mples as “true” split samples with Belews

Creek’s representative, using the same procedure discussed in the sample collection description

(Section 3.1).

The total mercury field blank sample for the in fluent to the bioreactor system (SP-7) and

for the effluent from the biorea ctor system (SP-8) were collect ed by shrouding one of the three

taps on the sample tap splitter with a clear pl astic bag. Before purging the sample tap, ASTM

Type 1 water was poured directly into the sample bottles under th e clear plastic bag.

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

influent to the bioreactor system (SP-7) and the effluent from th e bioreactor system (SP-8) were

collected by filling a 20-liter composite container with ASTM Type 1 water. The same T-splitter

tubing used to fill the metals composite container at each point was used with a pump to fill the

20-liter field blank composite cont ainer. Prior to attaching one e nd of the tubing to the sample

tap, it was placed directly into the container hol ding ASTM Type 1 water. The other end of the

tubing was attached to the vented cap on top of the 20-liter field blank composite container.

After enough volume was pumped into the 20-liter field blank composite container, the vented

cap was replaced with a closed cap and the contai ner was placed on ice in a covered plastic trash

can. The vented cap used for the field blank coll ection was the same cap that was later used for

the metals composite container.

After 24 hours, the ASTM Type 1 water in th e 20-liter field bla nk 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 pump ed through the tubing and “Y” splitter, and

into the sample bottles. EPA collected the fiel d blank samples as “true” split samples with

Belews Creek’s representative, using the same procedure discussed in the sample collection

description (Section 3.1). Prior to filling the sample bot tles, the tubing was purged with

approximately one liter of ASTM Type 1 water. First the samplers collected 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 one liter of ASTM Type 1 water. The

samplers then collected the dissolved metals by 200.8, dissolved metals by 200.7, and dissolved

hexavalent chromium field blank samples.

No metals were detected in the field blank samples above the quantitation limit,

indicating that there was no cont amination from the sample collection procedures. Appendix

Tables A-16 through A-24 present al l the analytical results for the field blanks from each of the

# 5-4 sampling points, including all qua lified results and all results th at were measured above the

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

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 re lative percent difference (RPD) between 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 influent to the

bioreactor system (SP-4) and th e effluent from the bioreactor system (SP-5) during day 3 and

day 2 of the sampling episode, respectively. Th e duplicate samples were analyzed for all

analytes. Tables 5-1 and 5-2 present the anal ytical results and the RPD for SP-4 and SP-5,

respectively. Results are rounded to three sign ificant digits. Appendix Tables A-7 and A-13

present all the analytical results for the influent to the bioreactor syst em (SP-2) Day 3 and the

duplicate of the influent to the bioreactor system (SP-4) sample analyses , including all qualified

results and all results that were measured a bove the method detection limit, but below the

quantitation limit (i.e., J-values). Appendix Tabl es A-10 and A-14 present all the analytical

results for the effluent from the bioreactor system (SP-3) Day 2 and the du plicate of the effluent

from the bioreactor system (SP-5) sample analys es, including all qualified results and all results
