Instructions for Sample Collection, Packaging, and Shipment 

EPA Sampling Program

The samples you will be collecting are very important. The samples will be used by the 

U.S. Environmental Protection Agency (EPA) for revising the effluent limitations 

guidelines and standards for the Steam Electric Power Generating Industry. 

These instructions are being provided to Wabash Valley Power Association’s Wabash 

River Power Station to aid in collecting, packaging, and shipping samples for this 

sampling program. 

The plant must collect grab samples for all analytes at the sour water sampling points, 

and 24-hour composite samples for all analytes except mercury and cyanide at the vapor 

crystallizer (RCC) evaporator distillate stream sample point. At the vapor crystallizer 

(RCC) evaporator distillate sampling point, the plant must collect cyanide as a single grab 

sample and mercury must be collected as four individual grab samples over the 24-hour 

period (i.e., a grab sample collected every six hours). 

Samples must be collected Monday through Thursday during the week of January 31, 

2011. If the plant has any questions regarding the timeline or the steps provided, please 

contact Mr. Ronald Jordan at (202) 566-1003 or jordan.ronald@epa.gov. 

Equipment Needed

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

samples to the laboratories: 

• Sample bottles, composite containers, and tubing sets (specially-cleaned 

according to EPA Method 1669); 

• Automatic compositor; 

• Powder-free gloves; 

• Tyvek® coveralls or suitable alternative; 

• Dust masks (for use while collecting mercury samples) 

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

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

• Coolers; 

• Garbage bags; 

• Packing material; 

• Strapping tape; and 

• Traffic Report (will be provided by ERG). 
Sampling Points

The plant must collect samples Monday through Thursday during the week of January 31, 

2011 from each of the four sampling points specified below. Figure 1 identifies each of 

the sampling points for this sampling program. The following is a description of the four 

sampling points: 

• Sour Water Feed to the Treatment System (SP-1): This sampling point shall 

represent the combined condensate and chloride scrubber blowdown stream (D162 and E-166A/B) sour water feed to the carbon filter beds (V-166A/B) and 

degassing column (C-270). The sample shall be collected at the sample tap prior 

to the carbon filter beds. 

• Sour Water Return from the Sulfur Recovery Unit (SP-2). This sampling 

point shall represent the sour water return (V-241) from the sulfur recovery unit 

that is sent to the degassing column (C-270). The sample shall be collected prior 

to it combining with the sour water exiting filter beds V-167A/B. 

• Sour Water Feed to the Vapor Crystallizer (RCC) Evaporator (SP-3): This 

sampling point shall represent the sour water following ammonia stripping for the 

removal of NH3 and trace compounds. To avoid collecting a high temperature 

sample, this sample should be collected from the sample tap located immediately 

downstream of the E-271 heat exchanger. 

• Vapor Crystallizer (RCC) Evaporator Distillate (SP-4): This sampling point 

shall represent the distillate stream from the vapor crystallizer (RCC) evaporator 

system prior to any commingling with other plant water, such as cooling tower 

blowdown. This sample should be collected between the T-278 distillate tank and 

the P-278 pump.

Sample Bottles and Preservation

Table 2 identifies the sample bottles that are needed for collecting samples. The table 

also identifies the on-site preservation that is required for the samples. Please note that 

the number of sample bottles listed in Table 2 refers to the number of bottles that will 

need to be collected from each sampling point for each of the four sets of samples. For 

the Group II samples, the plant can either preserve the samples with sulfuric acid after 

sample collection, or the plant can order pre-preserved sample bottles. 

For the total cyanide samples, the plant should test the wastewater from the sampling 

points with lead acetate paper (turns black in the presence of sulfide) and potassium 

iodide starch paper (turns blue/violet in the presence of chlorine). If sulfide is present, 

the plant will need to dilute the sample with blank water until the sulfide is not detected 

by the lead acetate paper. If chlorine is present, then the plant will need to add sodium 

arsenite until the chlorine is not detected by the potassium iodide starch paper. After any 

dilution and/or sodium arsenite is added to the sample, the plant will need to preserve the 

sample with sodium hydroxide until the sample reaches a pH of 10 S.U. Please see 

ASTM Method D 7365-09a for more details on the preservation requirements for total 

cyanide.

NOTE: The number of sample bottles refers to the number of sample bottles needed for each sampling point for each of 

the four sets of samples. 
Sample Labeling

Label each bottle prior to collecting the sample so it can be identified by the laboratory. 

Each self-adhesive label must be completed in indelible ink and must contain the 

following information: 

• Sample number (see Table 3); 

• Sampling episode number (see Table 3); 

• Sampling point/description (see Table 3); 

• Date of sample collection; 

• Analysis to be performed; 

• Sample bottle type; and 

• Required on-site preservation. 

If any of the information is incorrect, the plant must revise the label using indelible ink. 

Once applied to the sample container, the plant must cover the labels with clear tape to 

prevent tampering, abrasion, smearing, or loss during transit. For metals and mercury 

samples, do not place labels directly on the sample bottles because of the potential for 

contamination. Instead, place the label on the outer plastic bag of the sample bottle. To 

ensure that the sample label does not become separated from the bottle, the doublebagged sample bottle should be placed in an additional Ziploc bag after collection. 

Please note however, that the labels can be placed directly on the metals and mercury 

sample bottles ONLY IF they are placed directly on the bottles in a clean laboratory 

environment. HOWEVER, any revisions to the labels by the plant must be made on a 

label placed on the outer plastic bag for the double-bagged sample bottle, and the changes 

noted in the traffic report. 

Table 3 provides the sampling point descriptions, sample numbers, and sampling episode 

number for the plant for this monitoring program. The information in the table should be 

provided on the sample bottle labels for the appropriate bottles. The “analysis to be 

performed” should be shown on the label as the following, depending on the specific 

analysis: 

• BOD; 

• Group I; 

• Group II; 

• Total Cyanide; 

• Total Metals – 200.8 w/ CC; 

• Total Metals – 200.7; 

• Total Mercury (for sour water feed to treatment, sour water return from 

sulfur recovery, sour water feed to vapor crystallizer (RCC) evaporator, 

and field blank samples); and 

• Total Mercury – Grab 1 (for vapor crystallizer (RCC) evaporator distillate 

laboratory composite samples. The bottles should be labeled as Grab 1, 

Grab 2, Grab 3, and Grab 4 for the four respective collection times). 
The “sample bottle type” should be shown on the label the same as the “Sample 

Container and Volume” column in Table 2, except that the quantity should not be 

included. For example, for total mercury, the “sample bottle type” should be “250-mL 

glass bottle.” The “required on-site preservation” should be shown on the label the same 

as the “On-Site Preservation” column in Table 2, except that “(acid preserve at 

laboratory)” does not need to be included for the total metals and total mercury sample 

bottles.

 The field blank can be collected during any of the sample sets, but the plant must use the sample number 

and sampling point description associated with the correct sample set (e.g., RCC Evaporator Distillate Field 

Blank – Set 2 – sample number 72461 if the field is collected during set 2). 

The laboratory will perform MS/MSD analyses on the total metals and total mercury 

analyses; however, no additional sample volume is required. 

Sample Collection

The plant must use clean sampling techniques when collecting the total metals and total 

mercury samples; therefore, the sampling team should follow the clean hands/dirty hands 

sampling techniques outlined in EPA Method 1669. Additionally, the plant must try to 

avoid significant contamination during sample collection, especially from sources such as 

airborne particles, dirt, and corrosion particulates from piping, railing, etc. 

The plant must collect grab samples for all analytes at the sour water sample points (sour 

water feed to treatment, sour water return from sulfur recovery, and sour water feed to 

RCC evaporator). The plant must collect 24-hour composite samples for all analytes 

except cyanide and mercury at the RCC evaporator distillate sampling point. The 24-hour 

composites must be set up to collect equal sample aliquots every hour over the 24-hour 

period. For mercury at the RCC evaporator distillate sampling point, the plant must 

collect four individual grab samples over the 24-hour period (i.e., one mercury grab 

collected every six hours). For cyanide at the RCC evaporator distillate sampling point, 

the plant must collect a single grab sample after one of the mercury grab samples. 

If the plant is able to collect the samples from a valve or tap, the plant can use the 

instructions provided in this section to set up and collect the composite samples at the 

RCC evaporator distillate sampling point. This section also provides instructions to 

collect the grab samples at the sour water sample points (sour water feed to treatment, sour 

water return from sulfur recovery, and sour water feed to RCC evaporator) and for the 

mercury and cyanide grab samples at the RCC evaporator distillate sampling point. Please 

note that the plant will need to install a two-way splitter on the tap for the RCC evaporator 

distillate sampling point to allow for the composite tubing to be connected to the tap and 

also have a tap available for the grab sample collection of the cyanide and mercury 
samples. If the pressure in the piping is not excessive, the compositor can be connected to 

backflush the composite sample tubing directly back into the piping. An alternative 

approach described below is also effective, and may be necessary if the pressure in the 

piping system is too high for the compositor to backflush the composite sample tubing 

into the piping. (NOTE: If the RCC evaporator distillate sampling point has intermittent 

flow which may interfere with the automatic composite collection, please contact TJ 

Finseth, (703) 633-1698 to discuss possible alternatives.) 

Composite Sample Collection 

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

the sample collection. 

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

3. Dirty hands opens the outer bag of the cleanbox and clean hands opens the 

clear inner bags and secures the cleanbox open with the clips located 

inside the box. 

4. Dirty hands opens the outer bag containing a length of precleaned silicone 

tubing, a “T” splitter, and two additional pieces of silicone tubing. Clean 

hands takes the inner bag containing the tubing and moves it into the 

cleanbox. Clean hands opens the inner bag and removes the tubing. Clean 

hands places a clean plastic bag over each end of the silicone tubing. The 

tubing configuration will be set up such that one end will be connected to 

the sample tap, one end will be threaded through the automatic compositor 

and connected to the large composite container, and one end will be 

placed next to a sump/drain near the sampling point. To collect the 

samples, the sample tap will be left open during the entire sample 

collection time period and will flow directly to the sump/drain; however, 

the automatic compositor will pull sample from the flowing stream as 

dictated by the sampling program. Additionally, the automatic compositor 

will be capable of purging the line back to the flowing stream between 

each individual sample aliquot. 

5. Dirty hands threads one portion of the silicone tubing through the 

peristaltic pump portion of the automatic compositor. 

6. Dirty hands opens the outer bag of the metals field blank water and the 

field blank composite container. Clean hands opens the inner bag for the 

field blank water, unscrews the lid and places it in the inner bag. Clean 

hands then places one end of the silicone tubing into the blank water. 

Clean hands also opens the inner bag for the field blank composite 

container and loosens the lid. Clean hands holds the silicone tubing with 

the plastic bag covering the end out of the cleanbox and over a bucket and 

dirty hands operates the pump to pump blank water through the tubing. 

After the tubing has been purged with sufficient volume, clean hands 

holds the silicone tubing at the mouth of the field blank composite 

container and fills the composite container with sufficient volume to 

collect the total metals field blank samples at the pump-off location. Dirty 

hands stops the pump. During the purging of the tubing and collection of 
the field blank sample volume, dirty hands pinches a portion of the 

silicone tubing that will be placed by the sump/drain. Clean hands places 

the plastic bag over the end of the silicone tubing, replaces the lid on the 

field blank composite container, places the silicone tubing back in the 

cleanbox, and closes the inner bag of the field blank composite container. 

Dirty hands closes the outer bag of the field blank composite container. 

7. Clean hands holds the end of the silicone tubing outside the cleanbox over 

a bucket, with the plastic bag still covering the end of the tubing. Dirty 

hands places the end of the silicone tubing near the sump/drain and opens 

the sample tap valve to allow the wastewater to flow through the tubing. 

Dirty hands operates the pump to purge the pump portion of the tubing for 

a minimum of 2 minutes. 

8. Dirty hands programs the automatic compositor to collect the 20 liters of 

sample over a 24-hour time period in one-hour intervals (i.e., collect 830 

mL of sample every hour). Dirty hands calibrates the compositor to ensure 

that 830 mL is being collected for each individual grab. 

9. Dirty hands opens the outer bag of the large composite container. Clean 

hands opens the inner bag and connects the silicone tubing to the port on 

the composite container, securing the connection with a cable tie. Clean 

hands closes the inner bag around the composite bottle, and dirty hands 

closes the outer bag. The samplers put ice around the composite container 

to keep the samples cold during the compositing time period. 

10. At the end of the composite sampling period, dirty hands stops each of the 

automatic compositors and opens the outer bag of each composite 

container. For each container, clean hands opens the inner bag and 

detaches the used tubing from the composite container and covers the port 

with a closed lid or small plastic bag. The samplers transport each of the 

composite containers, including the field blank composite container, to the 

pump-off area to pump off the samples into the specified sample 

containers. 

11. The samplers then repeat steps 1 through 10 (skipping step 6) to collect 

the composite samples for the next day of sample collection. 

 After the composite samples have been collected, the sampling team will then 

transfer the sample into the individual sample containers at the pump-off area. 

Sample Pump-Off Procedures 

12. Arrive at the pump-off location and prepare supplies and bottles for the 

sample collection. 

13. Clean hands and dirty hands put on Tyvek® suits and powder-free gloves. 

14. Dirty hands opens the outer bag of the cleanbox and clean hands opens the 

clear inner bags and secures the cleanbox open with the clips located 

inside the box. 

15. Dirty hands opens the opening on the peristaltic pump head so the tubing 

can be placed in the pump head. Dirty hands opens the outer bag 
containing a length of precleaned Teflon® tubing connected to a length of 

precleaned silicone tubing. Clean hands moves the tubing into the 

cleanbox and opens the inner bag and removes the tubing. Clean hands 

places a clean plastic bag over the end of the Teflon® and silicone tubing. 

16. Dirty hands threads the silicone tubing into the peristaltic pump head. 

17. Dirty hands shakes the field blank composite container to mix the sample 

and then opens the outer bag of the field blank composite container and 

total metals field blank sample bottle. Clean hands removes the total 

metals field blank sample bottle and places it in the cleanbox. Clean hands 

opens the inner bag of the field blank composite container, removes the lid 

from the container, and places the end of the Teflon® tubing in the blank 

water. Clean hands holds the end of the silicone tubing outside the 

cleanbox over a bucket, with the plastic bag still covering the end of the 

tubing and dirty hands operates the pump to pump about two liters of 

blank water from the field blank composite container. Clean hands places 

the end of the silicone tubing in the cleanbox, opens the inner bag of the 

total metals field blank sample bottle, and removes the lid. Dirty hands 

operates the pump to collect the total metals field blank sample and then 

stops the pump. Clean hands closes the lid on the sample bottle and closes 

the inner bag. Clean hands places the inner bag and bottle in the outer bag 

and dirty hands closes the outer bag. 

18. Dirty hands shakes the large composite container to mix the sample and 

then opens the outer bag of the large composite container for the metals 

samples and clean hands opens the inner bag. Clean hands transfers the 

Teflon® tubing from the field blank composite container to the metals 

sample composite container. Clean hands holds the end of the silicone 

tubing outside the cleanbox over a bucket, with the plastic bag still 

covering the end of the tubing and dirty hands operates the pump to pump 

about two liters of sample through the tubing and then stops the pump. 

19. Dirty hands opens the outer bag of the total metals by EPA Method 200.8 

sample bottle. Clean hands removes the inner bag and bottle and places it 

in the cleanbox. Clean hands opens the inner bag and removes the lid. 

Dirty hands operates the pump to collect the total metals sample and then 

stops the pump. Clean hands closes the lid on the sample bottle and closes 

the inner bag. Clean hands places the inner bag and bottle in the outer bag 

and dirty hands closes the outer bag. The samplers repeat the procedure to 

collect the total metals by EPA Method 200.7 sample. 

20. The samplers operate the pump to collect the BOD5, Group I, and Group II 

samples. NOTE: The samplers do not need to use the cleanbox while 

collecting these samples. 

Grab Sample Colletion 

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

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

gloves. 

3. Dirty hands gets a clear plastic bag and opens it slightly (touching only the 

outer part of the bag) so that clean hands can place hands in the bag and 

open the bag completely. 

4. Clean hands then uses the plastic bag to shroud the sample tap (note that 

there should be no flow through the sample tap at this time). Clean hands 

will need to puncture a small hole in the bag using the tap and dirty hands 

can cable tie the bag to the tap to prevent it from falling during sample 

collection. 

5. Dirty hands opens the outer bags of the field blank water and total mercury 

and total metals field blank sample bottles. Clean hands opens the inner 

bag of the field blank water and unscrews the lid. Clean hands then opens 

the inner bag of the total mercury and total metals field blank sample 

bottles. Clean hands pours the blank water into the field blank sample 

bottles under the shrouding, caps the bottles, and closes the inner bags. 

Clean hands then places the total mercury and total metals bottles in the 

outer bags and dirty hands closes the outer bags. 

6. Dirty hands then opens the valve to the sample tap and purges the tap for at 

least two minutes, then keeps the valve open until all samples have been 

collected. 

7. Dirty hands opens the outer bag for the total mercury sample bottle. Clean 

hands takes the sample bottle and inner bag and holds them under the 

shroud. Clean hands then opens the inner bag, opens the lid of the bottle 

and fills the total mercury sample bottle. Clean hands caps the sample 

bottle, closes the inner bag, and places the sample bottle in the outer bag. 

Dirty hands closes the outer bag. The samplers repeat this procedure for 

the collection of the total metals samples (both EPA 200.8 with collision 

cell and EPA 200.7), unless the plant is collecting the metals samples as 

composite samples. 

8. The samplers then collect the BOD, Group I, Group II, and total cyanide 

samples. NOTE: the samplers can collect these samples using the same 

technique as the mercury and metals samples, or they can remove the 

plastic bag shrouding and collect directly from the tap. 

9. The Group II and total cyanide samples must be preserved prior to 

shipment to the laboratories. Use the information provided in the “Sample 

Bottles and Preservation” section of these instruction for the preservation 

steps. Additionally, the BOD, Group I, Group II, and total cyanide samples 

should be placed on ice immediately after sample collection/preservation. 

Sample Packing and Shipment

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

laboratories. 
1. Make sure that each sample bottle has a label, and that the label correctly 

specifies the sample point. 

2. Tighten the lid on each filled sample bottle, being careful not to 

overtighten the lid. If bottle threads are dirty to where the lid is impeded 

from closing, clean the threads on the bottle being careful to not introduce 

contamination into the sample. Clean the sample bottle with a cloth rag or 

paper towel. 

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

into an ice chest with wet ice to cool. 

4. When each sample requiring ≤6°C preservation has reached the desired 

temperature, wrap each glass sample bottle with two layers of “bubble 

wrap” (or place bottle in two “bubble bags”). The bubble wrap must fit 

snugly and completely cover the sample bottle. Enclose each “bubblewrapped” container and plastic container in an individual sealable plastic 

freezer bag. 

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

ship samples to the laboratories. 

6. Place the classicals samples in the garbage bags in the coolers with proper 

end up, close the interior garbage bag by tying, or with a twist-tie. 

7. Add ice to the cooler to keep samples cold during shipment. Arrange blue 

ice or sealed plastic freezer bags filled with wet ice on top of the sample 

bottles (if samples require ≤6°C preservation). If using wet ice, place the 

ice inside two one-gallon sealable freezer bags. Put at least 4 × 1⁄2 gallons 

of ice (4 × 2.5 pounds of ice) in each large cooler and 2 × 1⁄2 gallons of ice 

(2 × 2.5 pounds of ice) in each small cooler. Use more ice when ambient 

temperatures are very high. Place the ice inside the second garbage bag. 

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

9. Place the metals samples in the garbage bags in a different cooler with 

proper end up, close the interior garbage bag by tying or with a twist-tie. 

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

metals samples are not required to be cooled; however, because the metals 

and classicals are being analyzed by the same laboratory, the metals can 

be shipped with the classicals, but the metals samples would need to be 

chilled prior to packing them in the cooler with the classicals and ice 

would need to be added to the cooler between the interior and outer 

garbage bags to keep the samples cold. 

10. Fill in any free space around the bottles in the metals and classicals 

coolers with additional cushioning material. Sufficient packing material 

should be used so that the sample containers will not shift during 

shipment. 

11. Fill out and print a traffic report form for the classicals and metals samples 

(provided electronically by ERG). Seal the last two pages of the traffic 

report form(s) in a plastic envelope secured to the inside of the top of the 

cooler(s). NOTE: the top page of the traffic report must be sent to ERG at 

the following address: 
 Eastern Research Group 

 14555 Avion Parkway, Suite 200 

 Chantilly, VA 20151 

 Attn: TJ Finseth 

 (703) 633-1698 

12. Close the cooler(s). 

13. Place a completed laboratory address label on the lid of the cooler(s). The 

classicals and metals samples should be shipped to TestAmerica as 

follows: 

 TestAmerica 

 4955 Yarrow Street 

 Arvada, CO 80002 

 Attn: Elizabeth Eichelberger 

 (303) 736-0100 

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

the seal to ensure that the lid will remain closed if the latch is accidentally 

released or damaged. 

15. Place the mercury samples in the garbage bags in a separate cooler with 

proper end up, close the interior garbage bag by tying, or with a twist-tie. 

16. Do not add ice to the mercury cooler; simply close the second garbage bag 

by tying, or with a twist-tie. 

17. Fill in any free space around the bottles with additional cushioning 

material. Sufficient packing material should be used so that the sample 

containers will not shift during shipment. 

18. Fill out and print a traffic report form for the mercury samples (provided 

electronically by ERG). Seal the last two pages of the traffic report form 

in a plastic envelope secured to the inside of the top of the cooler. NOTE: 

the top page of the traffic report must be sent to ERG at the same address 

provided in step 11: 

19. Close the cooler. 

20. Place a completed laboratory address label on the lid of the cooler. The 

mercury samples should be shipped to Frontier as follows: 

 Frontier GeoSciences 

 414 Pontius Ave. North 

 Seattle, WA 98109 

 Attn: Patrick Garcia-Strickland 

 (206) 957-1428 

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

the seal to ensure that the lid will remain closed if the latch is accidentally 

released or damaged. 
22. Fill out the necessary paperwork for FedEx or UPS to prepare the 

shipment for pick up or drop off. NOTE: the samples must be shipped 

priority overnight to arrive at the laboratories the following morning. Ship 

the coolers to the laboratories. 

23. After the coolers have been dropped off (or picked up), please contact TJ 

Finseth at (703) 633-1698, to notify him that the samples have been 

shipped to the laboratories. 

Traffic Reports

An example traffic report will be provided to the plant by ERG for the first grab sample 

collection event. The plant will need to make changes to the traffic report electronically 

for the other three sample collection events. Some information, such as the date and 

sample collection times must be entered by the plant after the sample collection and 

therefore, will not be included in the example provided by ERG. 

After the traffic report is completed by the plant, the plant must print the four pages in the 

file. The last two pages in the file must be placed in the cooler for shipment to the 

laboratories and the first page must be sent to ERG. The plant can keep the second page 

of the traffic report. 

Engineering Data and Process Flow Diagram

The plant must provide engineering data regarding the operation of the plant and 

gasification wastewater treatment system during the sample collection period. 

Additionally, the plant must make some field measurements when samples are collected, 

including pH, temperature, and visual observations, and provide the data to EPA after the 

sample collection period. The engineering data and field measurement data requirements 

are in an Excel® spreadsheet titled “Monitoring Program Engineering Data Tables.” The 

tables are also included at the end of this enclosure. The plant must also submit a detailed 

process flow diagram for the sour water and vapor crystallizer (RCC) systems, annotated 

to indicate the location of each sampling point. The process flow diagram must present 

sufficient detail to depict each process flow stream (influent, effluent, and recycle 

streams) associated with or contributing directly or indirectly to the sour water stream 

and the evaporator distillate streams. The plant must complete the engineering data sheets 

and field measurement sheets in the Excel® file and e-mail the completed forms, along 

with the process flow diagram, to TJ Finseth at thomas.finseth@erg.com. Note that any 

information claimed as confidential business information (CBI) must not be sent by email and must instead be sent via U.S. postal service or by courier (e.g., Federal Express). 

Certification Statement 

The individual responsible for directing and supervising the sample collection and the 

engineering data preparation must sign the certification statement (provided in Enclosure 

4) and submit it upon the completion of the sampling program. The signed certification 
statement should be scanned and e-mailed to TJ Finseth at thomas.finseth@erg.com, at 

the same time the engineering data is submitted.

Confidentiality

A business ("you") may not withhold information from EPA on the grounds that it is 

confidential. You may, however, if you desire, assert a business confidentiality claim covering 

part or all of the information that you furnish to EPA. 

EPA regulations concerning confidential business information are contained in 40 CFR Part 2, 

Subpart B. The manner of asserting such a claim is specified in 40 CFR 2.203(b). Information 

covered by such a claim will be disclosed by EPA only to the extent, and by means of the 

procedures, set forth in Subpart B.
