# 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 December 5-10, 2010, at Allegheny Energy’s Ha tfield’s Ferry Power Station (Hatfield’s

Ferry), located in Masontown, Pennsylvania (S ampling Episode 6564). The focus of Episode

6564 was to characterize the purge stream ente ring the flue gas desulfurization (FGD)

wastewater treatment system and the efflue nt 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 seven coal-fired steam electric plants for FGD wast ewater sampling based

on the process configurations and characteristics of the plants.

Hatfield’s Ferry was selected by EPA for sampling based on the following site

characteristics:

 

# The plant is a coal-fired pow er plant that burns a ble nd of bituminous and PRB in

each of its three generating units;

 

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

 

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

includes the following steps:

— Equalization,

— Lime addition (pH adjustment/m etal hydroxide precipitation)

— Organosulfide addition,

— Ferric chloride addition,

— Polymer addition,

— Clarification,

— Hydrochloric acid addition (pH adjustment),

— Filtration (sand filters); and

 

# The plant operates a selective non-catal ytic reduction (SNCR) system on Unit 3.

# 1-1 1.3 Sampling Episode Overview

EPA and its technical contractor, Eastern Research Group, Inc. (ERG) conducted a oneday pre-sampling site visit at Hatfield’s Ferry on February 1, 2010 as part of the detailed study.

The information collected during the pre-sampling site visit and subsequent follow-up telephone

calls to Hatfield’s Ferry representatives was used to create Sampling Plan, Allegheny Energy’s

Hatfield’s Ferry Steam Electric Plant (Sampling Plan) [1], which describes the sample collection

procedures used during the sampling episode.

On Sunday, December 5, 2010, EPA arrived at Hatfield’s Ferry to meet with plant

personnel, receive on-site safety training, review the sampling 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 (December 6–10, 2010). The fo llowing personnel participated in EPA’s

sample collection activities:

 

# Ron Jordan, EPA/EAD;

 

# TJ Finseth, ERG;

 

# Jessica Gray, ERG;

 

# Danielle Lewis, ERG;

 

# Jennifer Lewis, ERG; and

 

# Brandon Smith, 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 episod e, UWAG acted as Hatfield’s Ferry’s representative and

collected samples on be half of the plant.

# O VERVIEW



# Hatfield’s Ferry operates three steam electric units and each has a coal-fired boiler. Units

1, 2, and 3, which came on line in 1969, 1970, and 1971 respectively, each have a net capacity of

570 megawatts (MW). In 2009, all three generating units burned a blend of 75% bituminous and

25% PRB coal; however, during the sampling ep isode the blend ranged from 58% bituminous

and 42% PRB to 84% bituminous and 16% PRB. Th e Hatfield’s Ferry main plant is located on

206 acres in Masontown, Pa. The plant also has a 246 acre landfill, but only 66.5 acres were

active at the time of the sampling episode.

Hatfield’s Ferry recently retr ofitted all three un its with wet FGD scrubber systems to

control the sulfur dioxide (SO 2 

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

June 2009, and the Unit 2 and Unit 3 FGD systems we re both installed in October 2009. With the

recent addition of the FGD scrubber systems, Hatfie ld’s Ferry also insta lled an FGD wastewater

treatment system to control the discharges of the wastewater generated during the operation of

the FGD scrubbers. The FGD scrubber systems are discussed further in Section 2.1 and the FGD

wastewater treatment system is discussed further in Section 2.2.

The plant operates a selective non-catalytic reduction (SNCR) system only on Unit 3 to

control nitrogen oxide (NO

x 

# ) releases from that unit. Hatf ield’s Ferry also uses low NO

x 

# burners

on all three units to control NO

x 

# releases from the plant.

The electrostatic precipitators (ESPs) at Hatf ield’s Ferry are particulate control devices

that remove the fly ash and other particulates from the flue gas. Hatfield’s Ferry utilizes coldside ESPs to remove the fly ash from all three units. The ESPs are designed to remove 99 percent

of the fly ash from the flue gas. The fly ash a nd other particulates are collected in hoppers and

are pneumatically transfe rred to fly ash silos.

Units 1 and 2 have the following configuration:

 

# Boiler;

 

# Air heater;

 

# ESP; and

 

# FGD scrubber system.

Unit 3 has the following configuration:

 

# Boiler (SNCR system located in boiler);

 

# Air heater;

 

# ESP; and

 

# FGD scrubber system.

2.1 FGD Scrubber System

Hatfield’s Ferry operates three forced oxida tion wet FGD scrubber systems (one per unit)

to control the emission of SO 2 

# from the units. The plant uses limes tone slurry as the sorbent for

SO 2 

# absorption. Limestone and service water are fed to three on-site ball mills (one per unit),

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 large for use in the FGD system. The

# 2-2 underflow from the hydrocyclones is sent back to the ball mills for processing. The overflow

from the hydrocyclones, which ranges from 22 to 25 percent solids (by weight ), is transferred to

the limestone slurry storage tank and then used as fresh limestone slurry in the absorber.

The fresh limestone slurry is fed to the reac tion tank of the FGD systems where the slurry

is pumped to the various levels of the FGD scrubbe rs with the recycle pump s. All three absorbers

have five spray levels, but the plant usually on ly operates four spray levels at one time. The

slurry is pressurized and sprayed downward into the scrubber vessel through spray nozzles. As

the slurry falls downward and the flue gas flows counter-current to the sl urry, the spray droplets

of the limestone slurry contact the flue gas and absorb the SO 2 

# , which reacts with the limestone

particles and produces calcium sulfite. The spray droplets flow downward until they settle on the

first of two dual flow trays, forming a layer of sl urry that the flue gas must pass through to exit

the FGD system. The tray has small holes in it that allow the flue ga s to bubble through the

limestone slurry layered on the tray, which pr ovides additional contact between the limestone

slurry and the flue gas. The spray droplets fall downward to the second dual flow tray and then

continue to flow downward in the scrubber unt il it reaches the reaction tank. Hatfield’s Ferry

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

gypsum).

The source of up to 50% of the make-up wate r used in the FGD systems at Hatfield’s

Ferry is recycled wastewater treatment lagoon water. The rest of the make-up water comes

directly from the Monongahela River. Hatfield ’s Ferry personnel stated they cannot use lagoon

water for more than 50% of the makeup water, othe rwise it is difficult for th e plant to control the

pH within the FGD system. All wastewater generate d at the plant, except for FGD wastewater, is

transferred to the wastewater treatment lagoon, which includes bo ttom ash sluice water (after

initial settling and pH adjustment), floor drain wastes, and boiler wash water.

Hatfield’s Ferry intermittently blows down the gypsum slurry from the absorber vessel to

control the solids and chlorides concentration in each of the scrubbers . The plant initiates a

blowdown once solids reach 21% within the absorber. The plant continues to blowdown until the

solids reduce to 18-19% within the absorber. The pl ant also monitors the chloride level in the

absorber; however, by maintaining the correct leve l of solids, the plant maintains an adequate

chloride level in the absorber between 8,000 and 10,000 ppm without the need for additional

blowdown. The maximum allowable chloride concen tration for the absorber is 12,500 ppm. For

all three units, blowdown from the absorbers occurs in six hou r increments with four to five

hours between each blowdown. Hatfield’s Ferry transfers the blowdown from the scrubber

absorber to the gypsum dewatering operations.

The scrubber blowdown is pumped to the prim ary hydrocyclones (one per unit) where the

solid gypsum is separated from the water by cen trifugal force. The solid gypsum is forced

outward to the walls of the hydrocyclones and fa lls downward, while the wa ter exits the top of

the hydrocyclones. The underflow from the primar y hydrocyclones is transf erred to the vacuum

filter belts. The overflow from the primary hydrocyc lones can either be transferred to the reclaim

tanks and ultimately goes back to the absorber , or the overflow is pumped to the secondary

hydrocyclones. The underflow from the secondary hydrocyclones is transferred to the reclaim

tank and recycled back to the absorber. The overflow from the secondary hydrocyclones is

pumped to the FGD wastewater treatment sy stem. The secondary hydrocyclone overflow is

never recycled back to the absorber.

# 2-3 Hatfield’s Ferry does not wash the gypsum sent to the vacuum filter belts as the gypsum

is poured onto the belts. The pl ant stated that although the syst em is designed to wash the

gypsum to remove chlorides, the plant does not conduct this wash because Hatfield’s Ferry does

not have any contracts in place to sell the gypsum. Additionally, washing the gypsum would

cause their average monthly discharge flow rate to rise above their current NPDES permit limit

(160 gpm). The gypsum contains a moisture co ntent of 10% after th e vacuum belt filters.

Hatfield’s Ferry transfers the gypsum to an on-s ite landfill for disposal. The landfill is lined and

has a leachate collection system. The filtrate from the vacuum belt filters is transferred to the

reclaim tanks and ultimately recycled back to the absorber.

2.2 FGD Wastewater Treatment System

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

secondary hydrocyclone overflow. The design flow rate for the treatment system is 500 gpm.

Hatfield’s Ferry operates the FGD wastewater treatment system 24 hours per day, 7 days

per week. The wastewater treatment system wa s installed to treat the FGD scrubber purge

wastewater to meet the plant’s permit limits. The plant’s FGD wastewater treatment system

contains the following treatment operations:

 

# Equalization;

 

# Lime addition (pH adjustment/m etal hydroxide precipitation);

 

# Organosulfide addition;

 

# Ferric chloride addition;

 

# Polymer addition;

 

# Clarification;

 

# Hydrochloric acid additi on (pH adjustment); and

 

# Filtration (sand filters).

Figures 2-1 and 2-2 located at the end of this section, presen t process flow diagrams of

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

episode. Figure 2-1 presents a simplified diag ram of the FGD wastewater treatment system.

Figure 2-2 presents a more complex diagram provi ding more detail on the chemical precipitation

treatment operations.

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 contain between 4 and 7 percent

solids, had a pH between 6 and 7 S.U., a nd a temperature between 40 and 50 °C. The

equalization tank also receives water from the wa stewater treatment sump and off-specification

effluent from the FGD wastewat er treatment system. The wastewater treatment sump includes

wastewater such as filter back wash and filtrate from the filter pr ess that dewater the sludge from

the clarifiers. Sumps from the dewatering area ar e also transferred to the equalization tank;

however, the sumps in the limestone preparation are not transferred to the equalization tank.

From the equalization tank, the wastewater flows into the bottom of reaction tank 1.

Hatfield’s Ferry adds lime to reaction tank 1 to encourage metal hydroxide precipitation and to

increase the pH from 5.5 S.U. (pH in the abso rber) to between 8.5 and 9.0 S.U. Service water is

used to create the hydrated lime. Hatfield’s Ferry also adds an organosulfide, Nalmet® 1689, to

# 2-4 reaction tank 1 to encourage the formation of sulfide complexes. The overflow from reaction

tank 1 flows to reaction tank 2 wh ere ferric chloride is added.

From reaction tank 2, the wastewater is split ev enly between two solids contact clarifiers.

Right before this split, a polymer is added to the wastewater. As of the time of the site visit, one

clarifier was out of service and being repaired, and all wastewater was being transferred to the

second clarifier. [QUESTION FOR HATFIELD’S FERRY: Was one of the clarifiers out of

service during the sampling episode? If so, wh ich clarifier?] Both solids contact clarifiers

contain a sludge bed that facilitates removal of the solids in the wast ewater. A portion of the

sludge from the clarifiers can be recycled to r eaction tank 1, while the majo rity is transferred to

the sludge tank and then pumped to a filter press for dewatering. At the time of the sampling

episode, the plant was not r ecycling any of the clarifie r sludge to reaction tank 1.

The dewatered sludge, which contains approxima tely 75% solids, is transferred to the onsite landfill, along with the gypsum . The filter press filtrate is transferred to the wastewater

treatment area sump and recycled back to the eq ualization tank.

The clarifier overflow is transferred to the sa nd filters (gravity filtration); however, prior

to reaching the sand filters, hydrochloric acid is in jected into the waste stream to decrease the pH

to 7.0 S.U. The backwash from the sand filters is transferred to the wast ewater treatment area

sump, which is recycled b ack to the equalization tank.

After treatment with the sand filters, the wastew ater is collected in the treated wastewater

storage tank. From this tank, the wa stewater is either recirculated back to the equalization tank or

mixed with the effluent from the treatment la goon and discharged to the Monongahela River.

Discharge from the wastewater treatment sy stem is continuous, unless the plant is

recirculating the effluent because it is not mee ting specifications. The plant’s permit limit for its

average monthly discharge flow rate is 160 gpm, th erefore the plant attempts to keep the average

daily discharge at 160 gpm. The wastewater treatm ent system is designed for typical flow rates

between 100 and 500 gpm. The hydraulic residen ce time of the FGD wastewater treatment

system is 24 hours.

2.2.1 Sampling Points

Figure 2-2 shows the sampling points for the Ha tfield’s Ferry sampling episode; they are

summarized below:

 

# A sample of the secondary hydrocycl one overflow from an individual unit 1 

# , which

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

chemical addition or mixing with recycle streams); and

 

# A sample of the effluent from the trea ted wastewater storage tank, before mixing

with the treated wastew ater lagoon effluent.

1 

# During each day of the sampling episode, ERG collected the secondary hydrocyclone ov erflow from one unit.

Over the course of the four-day sampling episode, ERG collected the secondary hydrocyclone overflow once from

Unit 1, once from Unit 2, and twice from Unit 3.

# During the Hatfield’s Ferry 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. Figures 2-1

and 2-2 of this report present flow diagrams of the plant’s wastewater treatment 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 of 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 split samples with Hatfield’s Ferry’s

representative by inserting a “Y” splitter into the sample tubi ng configuration at each sampling

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 Hatfie ld’s Ferry’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

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.

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 the FGD wastewater treatment system (SP-1) was collected from a sample

tap located on the wastewater piping on the ove rflow line from the secondary hydrocyclones.

Because Hatfield’s Ferry does not have a sa mple tap located downstream from where the

secondary hydrocyclone overflow for each unit is combined, one unit’s secondary hydrocyclone

overflow was sampled each day 2 

# . Figure 2-2 identifies the sampling location for SP-1. This

sample was collected as a grab sample. Due to the relatively high concentration of suspended

solids, the FGD purge was not amenable to co llecting representative split samples using

composite sampling techniques. This was not an issue for samples collec ted at SP-1 because the

characteristics of the influent to the wastewater treatment syst em are expected to be fairly

consistent during the purge. The sampling poi nt was located inside the gypsum dewatering

building, at the location of the secondary hydr ocyclones. Because the sampling point was

located inside, there were no wind or rain concerns 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-4) 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, a 3/8 inch hose barb was attached to the sample tap tubing to reduce the diameter of the

sample tap. The sample tap was only a couple fe et off the ground and because the wastewater at

the tap was not pressurized, the samples eith er had to collected on the ground, or on the

level/floor below the secondary hydrocyclones. Therefore, the samplers attached a 15-foot

length of silicone tubing to the sample tap, a nd carefully lowered the tubing through the opening

in the secondary hydrocylones down to the level be low. The end of the silicone tubing was fitted

with a “Y” splitter, with two addi tional lengths of silicone tubi ng attached to the “Y” splitter.

The samplers attached the silicone tubing to the hose barb, opened the valve, and allowed sample

to flow through the tubing and hose barb 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).

2 

# Secondary hydrocyclone overflow from Unit 3 was sampled on day 1 and day 4. Secondary hydrocyclone

overflow from Unit 2 was sampled on day 2 and secondary hydrocyclone overflow from Unit 1 was sampled on day

3.

# 3-3 The samplers collected the following samples using a “cleanbox,” as described in Section

3.1:

 

# Total and dissolved mercury;

 

# Total metals by 200.8; and

 

# Total metals by 200.7.

Samplers then filled a 10-liter 3 

# 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 tr ansported 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 Hatfield’s Ferry’s representatives. The sampling team placed

the end of the Teflon® tubing into the 10-liter container filled with wastewater from the influent

to the FGD wastewater treatment system. By this time, the solids in the wastewater had been

settling for approximately 120 minutes. Approxi mately 0.5 liters of sample were pumped

through the tubing/filter to purge th e line before collecting samples 4



# .

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

Section 3.1:

 

# Dissolved metals by 200.8;

3 

# On day 3 and day 4, two (2) 10-liter containers were collected for the dissolved metals pump off because the

sample collected on Day 2 did not result in enough supernatant to collect all sample fractions needed. ERG filled

one 10-liter container while Hatfield’s Ferry’s repr esentatives filled the other 10-liter container.

4 

# On day 3 and 4, one 10-liter container was used to collect the 200.8 dissolved metals sample volumes. The sample

tubing was then moved to the second 10-liter container, pu rged with 0.5 liters of sample, and the remaining sample

volumes were collected.

# 3-4  

# Dissolved metals by 200.7; and

 

# Dissolved hexavalent chromium5.

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

3.1.2 Effluent from FGD Wastewater System

The effluent from the FGD wastewater system (SP-2) was collected from a sample tap

downstream of the treated wastewat er storage tank on the suction side of the pump that directs

the wastewater to the river for discharge. EPA decided to sample from the suction side of the

pump because Hatfield’s Ferry does not always transf er treated effluent to th e river; therefore, if

the sample was located on the discharge side of the pump, then EPA would not be able to collect

sample aliquots when the discharge was not occurring. [QUE STION FOR HATFIELD’S

FERRY: Please confirm the sample tap location.] Hatfield’s Ferry installed a three-way splitter

on the sample tap, which had three separate taps to collect samples from the sampling point. The

sample tap was located inside the FGD wastewat er treatment building (see Figure 2-2 for the

sampling location for SP-2). Because the sampling point was located inside, there were no wind

or rain concerns during the sample collection.

ERG collected the effluent from the FGD wastewater treatment system composite

samples using two automatic compositors which were programmed to collect individual sample

volumes into two 20-liter containers. The comp ositors were programmed 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-5) 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 samp le collection procedures at the effluent of the FGD wastewater

treatment 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

5 

# On day 2, the samplers were unable to collect the he xavalent chromium sample because there was not enough

supernatant in the 10-L container after allowing the solids to settle.

# 3-5 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 6



# .

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.

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. Because the sample tap was located on the suction side of the effluent transfer

pumps, the head from the wastewater storage ta nk level was the only pressure moving the water

through the piping. Because of this reduced pres sure, when the samplers opened the third valve

on the sample tap to collect the mercury sample s, no wastewater was drained. Therefore, to

collect the mercury sample, the sa mpling team pinched the drain lin e of the T-splitter tubing set

for the both the metals and classical compositors to obtain flow through the tap used for mercury

sampling. After purging the tap for two minutes, the samples were collected directly from the

tap into the sample bottles. After the samples were collected the drain line in the T-splitter tubing

sets for the compositors were released and allo wed to flow normally. Because total mercury and

dissolved mercury samples were collected directly from the tap, ERG was not able to collect split

samples with Hatfield’s Ferry’s representatives ; therefore, duplicate samples were collected.

ERG collected another set of tota l and dissolved mercury samples every six hours thereafter over

the 24-hour period. The plastic shroud was replaced for each set of mercury grab samples. After

collecting each set of mercury grabs, ERG fille d a field test bottle and tested for pH and

temperature using four-colored pH paper, a pH meter, and a thermometer. Table 3-3 presents the

field measurement data for the effluent of the 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 Hatfield’s Ferry ’s representatives; therefore, duplicate samples were collected.

The total cyanide sample was immediately preser ved with sodium hydroxide to a pH >10 S.U.

and the samples placed on ice. Lead acetate test st rips and potassium-iodide starch test strips

were used to measure for sulfides and oxidant s, respectively. No sulfides or oxidants were

detected during the sampling epis ode at effluent from the FGD wa stewater treatment system.

6 

# On day 4 of sample collection, the samplers pinched the drain line of the T-splitter tubing set for the classical

compositor so there was only a drain line from the metals compositor. This approach provided a more consistent

flow for each of the compositors and still allowed both co mpositors to purge the line back to the flowing stream

prior to each individual sample aliquot, the classical just had to purge all the way back to the sample tap.

# 3-6 After the twenty-fourth aliquots were co llected in the two composite containers 7 

# , 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

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 “t rue” split samples with Hatfield’s Ferry’s

representative. On Day 1 only, prior to collectin g any samples of the effluent from the FGD

wastewater treatment system, the samplers collect ed a field blank sample (SP-5) for dissolved

and total metals. See Section 5.2.3 for a descripti on of the dissolved 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

7 

# The 20-liter metals and classical containers from day 1 were almost completely full at the end of the 24-hour

compositing period. There was only a small amount of head space in the vented cap. On day 2 the 20-liter classical

compositor was disconnected after only nine full aliquots be cause the 20-liter container was already full. On day 3

the metals composite container collected 22 liters of sample (and did not overflow) and the classical composite

container collected 21.5 liter of sample. On day 4 the metals and classical composite containers collected

approximately 20 liters each.

# 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 previo usly filled 20-liter container 8 

# . 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.

For mercury, ERG collected QC samples at the effluent from the FGD wastewater

treatment system (SP-2) on Day 3 of the sampli ng episode. ERG collected QC samples for all

other analytes at the effluent from the FGD wastewater treatmen t system (SP-2) on Day 4 of the

sampling episode. In addition, for mercury, ERG co llected a duplicate sample of the effluent

from the FGD wastewater treatment system (SP- 3) on Day 2 of the sampling episode. For all

other analytes, ERG collected a duplicate sample for the effluent from the FGD wastewater

treatment system (SP-3) on Day 3.

3.2 List of Analytes and Sample Preservation

Samples collected at Hatfield’s Ferry we re 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

8 

# On day 1 of the sampling episode, ther e was sufficient volume in the metals co ntainer; therefore, samplers did not

transfer the tubing to the other container. On day 2, because the classicals composite container was disconnected

(due to overfilling), the samplers collected all the samples from the metals composite container.

# 3-8 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 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 sulf ides 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, Hatfield ’s Ferry plant personnel provided the

sampling team with operational data for each of the generating units and the FGD scrubber

system, as well as operational and flow data for the FGD wastewater treatment system. Table 3-8

presents the unit operating characteristics, Tabl e 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.

 

# Collection of total and dissolved mercury samples at SP-2: Because the sample

tap was located on the suction side of the effluent transfer pumps, the head from

the wastewater storage tank level was th e only pressure moving the water through

the piping. Because of this reduced pre ssure, when the samplers opened the third

valve on the sample tap to collect th e mercury samples, no wastewater was

# 3-9 drained. Therefore, to collect the merc ury sample, the sampling team pinched the

drain line of the T-splitter tubing set for the both the metals and classical

compositors to obtain flow through the tap used for mercury sampling.

 

# Metals and Classicals Composite Containers at SP-2 (Day 1): On day 1 of

sample collection at the effluent from the FGD wastewater treatment system, the

samplers after the first 24-hour compositi ng period at the effluent from the FGD

wastewater treatment system (SP-2), samp lers disconnected the 20-liter containers

from the compositors and noted that both containers were completely full, filled

to above the 20-liter level. The number of complete aliquots collected is not

known.

 

# Collection of classicals samples at SP-2 (Day 1): On day 1 of sample collection

at the effluent from the FGD wastewater treatment sy stem (SP-2), the sampling

team collected the classicals samples from the same 20-liter container that was

used to collect the metals samples. There was sufficient volume remaining in the

metals composite container, after collecting the required dissolved and total

metals samples, to collect the samples for BOD, Group I analytes, and Group II.

 

# Collection of hexavalent chromium samples at SP-1 (Day 2): On day 2 of

sample collection at the influent to the FGD wastewater treatment system (SP-1),

the hexavalent chromium sample was not collected. After allowing the solids to

settle for approximately two hours, the sa mplers collected the dissolved metals by

200.8 and dissolved metals by 200.7. The samplers then began collecting the

hexavalent chromium sample but stopped when the bottle was approximately half

full because the filter became clogged w ith solids. Sampling activities were

paused and the sample was allowed to continue settling. During this time the

hexavalent chromium sample was capped and the inner bag was sealed and left

inside the clean box. The outer bag ar ound the clean box was closed. After

approximately one hour and twenty minut es, the 10-liter container was checked

for further settling. Due to the minimal supernatant present, EPA decided not to

collect the hexavalent chromium sample.

 

# Collection of classicals compos ite sample at SP-2 (Day 2) – On day 2 of sample

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

classical compositor was di sconnected after only 9 full aliquots. The container

was almost filled with 20-liters of samp le and samplers chose to disconnect the

compositor prior to the sample comple tely filling the 20-liter container.

 

# Collection of duplicate samples (SP-3) – As described above, on day 2 of

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

classical compositor overfilled during th e compositing period. ERG had planned

to collect the duplicate samples of th e effluent from the FGD wastewater

treatment system (SP-3) on day 2; ho wever, because only one 20-L container

would have volume for the sample collec tion, the metals and classical duplicate

samples were collected on day 3 instead. At the time the classical composite

container issue was identified, two of the four mercury duplicate samples had

# 3-10 already been collected; therefore, ERG continued collecting the mercury duplicate

samples on day 2.

 

# Collection of dissolved metals samples at SP-1 (Days 3 and 4) – On day 3 and

day 4 of the sample collection at the infl uent of the FGD wastewater system (SP2), two 10-liter containers were filled a nd allowed to settle before collection of

dissolved metals samples. ERG filled one of the 10-liter containers while

Hatfield’s Ferry’s representatives simultaneously filled an additional 10-liter

container. One container was used to collect all sample volumes needed for

dissolved metals 200.8. The pump off tubi ng was then transferred to the second

10-liter container, purged with appr oximately 250 mL of sample, and the

remaining sample volumes were collected.

 

# Collection of duplicate samples for total and dissolved metals, classicals, and

hexavalent chromium at SP-2 (Day 3) – On day 3 of the sample collection at the

effluent of the FGD wastewater system (SP-2), both classical and metals

compositors again collected more than the desired 20 liters of sample, with the

metals compositor collecting approxi mately 22 liters and the classicals

compositor collecting approximately 21.5 liter s. Samplers were present for the

final composite sample collection cycle and were able to verify that both

containers did not reach full capacity and we re able to hold the full volume of the

last sample. The sample volume collected on day 3 of sampling was used to

collect duplicate samples (SP-3) for total metals, dissolved metals, classicals, and

hexavalent chromium.

 

# Collection of QC samples at SP-2 – The QC samples for total and dissolved

mercury at the effluent from the FGD wa stewater treatment system (SP-2) were

collected on day 2, as planned; however, because the duplicate samples for total

and dissolved metals and classicals were collected on day 3 instead of day 2 (as

described above), ERG collected the QC samples for these analytes on day 4

instead of day 3.

# 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 Hatfield’s Ferry,

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

for mercury was collected on Day 2 of the samp ling episode and duplicate samples for all other

analytes were collected on Day 3. The Day 2 re sult for mercury presented in Table 4-2 represent

the average of the original and the duplicate samp le results and the Day 3 results for all analytes

other than mercury in Table 4-2 represent the average of the original and duplicate sample

results. Table 5-2 presents the analytical resu lts for the original and duplicate mercury results

from Day 2 and the calculated relative percen t difference (RPD). Table 5-3 presents the

analytical results for the original and duplicate re sults for all analytes other than mercury for Day

3 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

 

# 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-1 through A-14 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.

# Q UALITY



# Quality assurance/quality control (QA/QC) pro cedures applicable to the Hatfield’s Ferry

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 bla nks. Appendix Table A-15 presents all of the

analytical results from the bottle blank analyses for the bottles used to collect the metals and

mercury samples.

# 5-2 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 equi pment blanks, except for aluminum in the

sample tap tubing set and calcium in the pump off tubing set. Because the sample tap tubing sets

were only used for the collection of the influent samples, the aluminum contamination did not

affect the results of the sampling episode. Calciu m was detected in the pu mp off tubing set at 40

ug/L, and all calcium results for the sampling ep isode were more than 2,000 times greater than

the equipment blank detection. Appendix Table A-15 presents all of the an alytical 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 and total and dissolved mercury samples 9



# .

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

as “true” split samples with Hatfield’s Ferry ’s representative, usi ng the same procedure

discussed in the sample collec tion description (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)

9 

# 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 bl ank for the dissolved mercury sample. Mercury was not

detected above the method detection limit (0.24 ng/L) in the filtration blanks performed for each day of samples.

# 5-3 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 was purged with approximately one liter of blank water. 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 bo ttles. EPA collected the field blank samples as

“true” split samples with Hatfield’s Ferry’s repr esentative, using the same procedure discussed in

the sample collection desc ription (Section 3.1).

The total mercury field blank sample for the effluent from the 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 purgi ng the sample tap, ASTM Type 1 water was poured directly into

the sample bottles under the clear plastic bag.

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

effluent from the FGD wastewater treatment sy stem (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 20-liter 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 othe r 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 container was placed on ice in a covered plastic trash can. Th e 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 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

Hatfield’s Ferry’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 1.5 liters 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 approxim ately 0.5 liters 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.

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-16

through A-20 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).

5.2.4 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

# 5-4 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.



# 100

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 du plicate samples for the effluent from the

FGD wastewater treatment system (SP-3). The samplers collected the duplicate for mercury on

day 2, while the duplicate for all other analytes was collected on day 3. Table 5-2 presents

analytical results and the RPD for all analytes for SP-2 and SP- 3. Results are rounded to three

significant digits. Appendix Tabl es A-10, A-13 and A-14 present all the analytical results for the

effluent from the FGD wa stewater treatment system (SP-2) Day 2 for mercury and Day 3 for all

other analytes and the duplicate of the effluentfrom the FGD wastewater treatment system (SP3) sample analyses, including all qualified results and all results that we re measured above the

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