Section 1 – Background of Proposed Illinois EPA Water Temperature Standards

The Illinois Environmental Protection Agency (“Illinois EPA”) has proposed to

redesignate uses of the Chicago Area Waterway System, and revise water

quality standards, including the water quality standards for temperature.

See

Proposed 35 Ill. Admin. Code Parts 302 and 303.

Currently, Corn Products’ Argo Plant (“Argo”) is subject to thermal discharge

limitations for Sanitary & Ship Canal water used by the plant for noncontact

cooling.

The Sanitary & Ship Canal water provides cooling for a variety of heat sources

within Corn Products’ processes, with the amount needed based on production

rate and product mix. There are approximately 36 operations in the plant that

use Sanitary & Ship Canal water for cooling. The volume of Sanitary & Ship

Canal water that will be used for cooling varies based on the number of process

units in service at any given time.

The proposed revisions would result in the Corn Products’ wet milling operation

in Argo having to comply with water quality standards for Chicago Area

Waterway System and Brandon Pool Aquatic Life Use B waters, with period

averages and daily maximums not to exceed the limits set forth in the following

Section 2 – Possible Technical Alternatives

There were four technical options considered with regard to the use of Sanitary &

Ship Canal water for process cooling. The options include:

1.

Current Use Case

2.

Single Sanitary & Ship Canal Water Cooling Tower

3.

Unit Specific Closed Loop Cooling with Several Smaller Cooling

Towers

4.

Mechanical Cooling in Conjunction with Option 2

Option 1. The current use case, maintains the status quo. Corn Products’ corn

wet milling operation at Argo would continue to use Sanitary & Ship Canal water

as a cooling media for part of the process heat transfer scheme. Sanitary & Ship

Canal water use will range from approximately 20,000 gallons per minute up to a

maximum observed use of approximately 44,500 gallons per minute.

In this case, Corn Products would not be able to use Sanitary & Ship Canal water

as a source for process cooling as dictated by equipment design and production

demand. Based on the available historical data, the water returned to the

Sanitary & Ship Canal after use in the Corn Products process would exceed the

proposed temperature limits during some averaged periods as well as some daily

limits throughout a typical year.

This case documents that some financial burden on Corn Products will result due

to capital investment and increased costs for ongoing operations and

maintenance resulting from the addition of new equipment to maintain its

continued use by achieving compliance with the proposed standards.

The second alternative is the addition of a single cooling tower to cool water after

the process heat has been transferred to the cooling water, but prior to its return

to the Sanitary & Ship Canal. The main Sanitary & Ship Canal water supply and

return header is 42”

φ

. A suitable location on the Argo site in Bedford Park was

chosen to install a cooling tower sized for peak flow of 45,000 gallons per minute.

The cooling tower and associated pumps and piping will need proper foundations

and supports. In addition to Sanitary & Ship Canal water, instrument air and

electrical service will need to be supplied to the new cooling tower system. This

equipment would also require installation of a structural steel rack for routing of

utility piping and electrical service in conduits.

Cooling towers rely on evaporative cooling along with some sensible heat

transfer due to intimate contact with air for removal of heat. There is a practical

limit based on the area of the country chosen for the cooling tower installation.

This limit is based on the wet bulb temperature of the area. The assessment of

cooling tower effectiveness is based on wet bulb temperatures recorded at

Midway Airport in Chicago, Illinois.

---

3

Due to the volume of Sanitary & Ship Canal water, the cost of purchasing and

installing a cooling tower is high. The known, accepted wet bulb temperature

data for Chicago Midway along with expected cooling tower performance indicate

that there are times of the year when the period average will still be exceeded.

This alternative has a high capital cost along with additional on-going operating

and maintenance costs. In addition, even with this expenditure, the proposed

temperature period average limits will still be exceeded. Therefore, this option

was not considered a reasonable alternative.

Alternative 3 reduces the temperature of water returned to the Sanitary & Ship

Canal by implementing a closed loop cooling scheme for process heat removal.

The closed loop cooling scheme would consist of multiple cooling towers located

within the process battery limits in order to provide service to the process heat

exchangers.

It is reasonable to anticipate that the capital, operating and maintenance costs to

implement this scheme would be higher than the single Sanitary & Ship Canal

water cooling tower plan. For the estimated 36 process cooling loads, it is

expected that approximately 12 smaller cooling towers would be required. The

capital cost would be higher due to the cost of purchasing multiple towers,

installation of equipment in multiple water basins and routing of utility piping and

electrical service to different points throughout the plant as opposed to a single

location.

In addition to the cooling tower equipment installation costs, additional capital

equipment costs would likely be incurred to change expensive process heat

exchange equipment. The change in the process heat exchange equipment

would be driven by the new cooling water inlet conditions.

As a result of high capital costs, increases in on-going operating and

maintenance costs along with unknown technical impacts on the process, this

option was not considered a reasonable alternative.

The fourth alternative involves the installation of a mechanical cooling system in

conjunction with the single cooling tower discussed in the second option.

Mechanical cooling would be accomplished with the addition of a refrigerant

compressor and evaporator system. Like the closed loop cooling scheme,

mechanical cooling adds significant complexity.

Based on the heat balance calculations presented in Section 3, it is anticipated

that approximately 12,375 tons of mechanical cooling would be required to

achieve period average temperature limits. In addition to the investment in the

cooling tower installation, significant capital would be required for this type of

---

4

refrigeration system. This type of equipment would also require construction of a

building to provide shelter from the weather.

As a result of the high capital costs along with increases in on-going operating

and maintenance costs, this option was not considered a reasonable alternative.

Section 3 – Discussion of Proposed Cooling Tower Alternative

A single point of heat removal cooling tower was investigated for technical and

financial feasibility as the most reasonable option for reducing Sanitary & Ship

Canal water temperature prior to return back to the Sanitary & Ship Canal. This

option was selected for further investigation over the other investment cases for

two primary reasons. The first reason is that this was the method for heat

removal suggested by Illinois EPA as technically feasible and economically

reasonable. January 28, 2008 Hearing Transcript,

In the Matter of: Water

Quality Standards and Effluent Limitations for the Chicago Area Waterway

System and the Lower Des Plaines River Proposed Amendment to 35 Ill. Adm.

Code 301, 302, 303 and 304,

R08-9, p. 54-55, 67 (Ill.Pol.Control.Bd. Feb. 7,

2008). The second reason is that the other investment case solutions are more

complex, likely resulting in higher capital investment and life cycle costs.

a.

Selection of Periods for the Sanitary & Ship Canal Water Thermal Analysis:

The system operation logs from 12/1/2003 to 11/30/2007 were analyzed to

verify the maximum heat rejection to the Sanitary & Ship Canal water

system during 17 periods in a 12 month span as Illinois EPA Regulations

require.

b.

Calculation Method:

Sum of Daily Million btuH Q in each period was compared with the same

periods in the 4 year span (from 12/1/2003 to 11/30/2007) to verify the

period with the heaviest loading:

Q = Sigma (M * ((T dd-Max) - (T di-max)) * 500 /1,000,000)

Where:

T dd-max:

Daily Max Discharge Temperature (F)

T di-max:

Daily Max Inlet Water Temperature (F)

M:

Daily Avg Water Flow Rate (gpm)

Q:

btuH (not btuDay) / 1,000,000

The HISTORICAL DATA worksheet included in the Corn Products furnished

DMR Aspen Flow Calculator file was used for this calculation.

Since the average discharge water temperatures are available from

2/24/2005 to 11/30/2007, and average Sanitary & Ship Canal water

---

5

temperatures are not available, daily maximum discharge and Sanitary &

Ship Canal water temperatures are used in selecting the 17 design periods

covering a 12 month annual period.

(Please refer to Historical_Peak Periods worksheet included in Peak

Months_ 4 Years_040409 CC.xls.)

For the periods when the cooling water demands are diminished below

1,000 gpm, the heat load has been eliminated from the calculation.

i.

Daily Average and maximum Wet Bulb Temperatures for Chicago

Midway Airport:

NOAA weather data (hourly wet bulb temperatures recorded for Chicago

Midway Airport from 1/1/1998 to 12/31/2007), along with the tabulations for

daily average, maximum and minimum wet bulb temperatures for each

month for a period of 1998 through 2007 were evaluated for this calculation.

The projected average and maximum cooling tower discharge (leaving)

water temperatures were calculated for the selected peak thermal load

---

6

periods using the same daily average and maximum wet bulb temperatures

in the weather data.

(Please refer to Years 2004 thru 2007 worksheets included in CPI_Midway

WetBulbTemp_Stats-Siil_040609.xls for the daily average, maximum and

minimum wet bulb temperatures, which were used in the calculations.)

ii.

Cooling Tower Performance Tables:

The base performance table of the planned cooling tower was obtained from

Maddox Industries (Chicago Area Rep for Marley Cooling Towers) using the

Marley Model (ID 38) 664-5-3.

Due to insufficient coverage of the cooling tower performance data provided

by Marley, a portion of the operating performance outside the range of

coverage was approximated by extrapolating the base data. In addition, a

portion of the cooling tower performance data provided by Marley did not

cover specific points within the range of coverage. This data was obtained

by interpolating the performance data provided by Marley.

(Please refer to Marley Performance_040409 CC.xls for the projected

cooling tower performance, which was used in the calculations.)

iii. Period Average and Daily Maximum Water Temperatures:

The Corn Products furnished spreadsheet file (DMR Aspen Flow Calculator)

has been used in order to calculate the Period Average and Daily Maximum

Water Temperatures.

The Daily Maximum Water Temperatures were verified using the highest

WB temperature, and the maximum discharge water temperature (not

corresponding discharge water temperature to the same day for the highest

WB temperature).

If the Daily Maximum Water Temperatures are calculated using the

maximum discharge water temperature on the day when the highest WB

temperature occurs for each period, the results will be 2°F to 3°F lower than

the estimated daily maximum water temperature profile.

For the period average water temperature calculation, the corresponding

average wet bulb temperature was used for each period.

iv. 24 Hour maximum and Average Water Temperatures:

Under the Historical Data Worksheet of DMR Aspen Flow Calculator file, the

24 hour maximum discharge temperatures are listed for all dates (from

9/26/03 to 12/1/07), but the 24 hour average discharge temperatures are

listed for a period (2/23/05 thru 12/1/07) only.

---

7

The 24 hour average discharge temperatures for the missing period (from

9/26/03 to 2/22/05) have been estimated using the differences between the

average <24 hour maximum discharge water temperatures> and average

<24 hour average discharge water temperatures> for the same periods,

which are listed the Historical Data Worksheet from 9/26/03 to 12/1/07.

c.

Discussion of Opinion of Probable Cost:

As part of the evaluation of options to meet the proposed temperature limits an

analysis was completed to determine the capital cost to purchase and install a

new cooling tower system. Conceptual engineering was completed based on an

area selected on the Argo site as the most likely location for a new Sanitary &

Ship Canal water cooling tower.

A candidate cooling tower was selected by providing rough design parameters to

an established cooling tower vendor, Marley Cooling Towers, of SPX Cooling

Technologies, Inc. Pumps for supplying and discharging water from the cooling

tower were selected using hydraulic calculations based on engineering judgment

for the proposed site. Using the electrical power requirements for the selected

cooling tower and pumps, a material take-off for electrical power distribution

equipment and wiring was created. Finally, an estimated quantity of concrete

and steel required for the cooling tower basin and pump and cooling tower

supports along with a rack system for supporting pipe and conduit was

generated.

The opinion of probable cost for complete installation was based on a

combination of budgetary equipment quotes, engineering material take-offs and

the use of ICARUS cost estimating database. The opinion of probable cost for

this system is approximately $23,645,000. Based on a risk analysis, there is a

90% confidence level that the scope of work as described will not exceed this

opinion of probable cost.

Section 4 – Conclusion

The cooling tower alternative was chosen for more in depth study than the other

two alternatives due to the wide application for removal of heat from water and

the belief that this would allow the continued use of Sanitary & Ship Canal water

by economically bringing the returned Sanitary & Ship Canal water into

temperature compliance with the proposed limits. The cost of this alternative is

approximately $23,645,000. Additional capital investment as well as increased

operating and maintenance costs would be incurred as this technology was not

found to be sufficient to assure compliance on a consistent basis.
