This memorandum summarizes the teleconference discussion points.

Background on Steam Electric Detailed Study and Introductory Remarks

EPA provided backgroun d on the study of the steam electric industry and discussed that as the study is concluding, there are some data gaps remaining, such as combined cycle system operation and wastewaters. EPA stated that the purpose of the site visit at Kinder Morgan is to learn more about the plant ’ s operations, specifically the combined cycle system operations, and

the characteristics and handling of generated wastewaters

.

Site Visit Logistics

**•** EPA stated that the site visits conducted during this study have usually con sisted of the following:

o Check in

o Safety briefing

o Introduction to the plant

o TourMemorandum September 18 , 2009 Page 2

o Debrief from the tour/questions

**•** EPA stated that they will come prepared with hard hats, steel

- toed shoes, safety glasses, and hearing protection for the tour. Kinder Morgan st ated that EPA/ERG staff should wear long sleeves, long pants, and thick soled, leather shoes to the plant. Kinder Morgan also stated that back

- up hard hats and eye/ear safety will be

on hand.

**•** EPA stated that there will be four EPA/ERG staff on the site vis it : Ron Jordan and

Jezebele Alicea , EPA and Sarah Holman and Elizabeth Sabol , ERG.

**•** Kinder Morgan instructed EPA/ERG to park in the administrative parking lot that is clearly identified.

**•** EPA and Kinder Morgan agreed to begin the site visit at 7:30 A M EDT on Th ur sday , September 24, 2009

.

**•** Wayne Frey provided his cell phone number, 517

- 740

- 6612, and the front desk phone number, 517

- 841

- 5785.

Brief Overview of the Plant

**•** Kinder Morgan stated that they are a “demand dispatch” facility with peaking (“peak shav ing”) and intermediate load capability. Due to the depressed industrial load this year, Kinder Morgan has not run as much in the “reliability dispatch” mode.

**•** Kinder Morgan stated that the plant was last dispatched on August 27, 2009.

**•** Kinder Morgan state d that their typical peaking operations include start ing up in the morning, follow ing the load peaks throughout midday and into the evening,

and then shut ting down

.

**•** Kinder Morgan was a brownfield development. Kinder Morgan entered into an agreement with t he C ity of Jackson to tear down the GoodYear f actory, build its facility, and use all existing water and sewage infrastructure. Kinder Morgan discharges water to the local POTW. It has never had a reason to develop a

different drain age system (i.e., discha rge to surface water)

.

**•** Kinder Morgan first attempted a greenfield development, but the country township would not allow it.

**•** Kinder Morgan is located in Jackson in a residential area.

Brief Overview of the Combine Cycle Systems

**•** Kinder Morgan stated that the combined cycle system at the plant have a unique configuration because Kinder Morgan was designed to be a peaking plant. Kinder Morgan operates a hybrid combined cycle system , which includes six aeroderivative (jet engine) combustion turbines and one F rame 7 EA combustion

turbine , to serve a market, “intermediate load” nitch.

**•** Kinder Morgan noted the following about the combustion turbines used at the plant :

o Kinder Morgan uses low sulfur natural gas to fuel the combustion

turbines . Kinder Morgan does n ot also use liquid fuel due to the changes in air permitting that it would require.

o Kinder Morgan stated that 10 MW of steam power is produced from each

50 MW combustion turbine . 3 MW of the 10 MW steam produced is putMemorandum September 18 , 2009 Page 3

back into the turbine for NO

x

o Kinder Morgan uses steam for NO suppres sion

. 1.5 MW of the 3 MW consumed is gained back in additional power generation.

x

o The Frame 7 EA turbine is a relatively old technology , but the “low NOx”

ve rsion was relatively advanced at the time it was installed . Kinder Morgan stated that this type of turbine does not operate efficiently in

s imple cycle mode

. I f the boiler is designed correctly, this type of turbine

is much more efficient in a combined cyc le system, in which heat is

recovered. suppression because it is less damaging to the engine than water.

o The Frame 7 EA turbine is more ideal for a peaking application because it is efficient at starting up and shutting down.

**•** Kinder Morgan stated that even though the ir combined cycle system configuration is unique, the wastewater generated is similar to other combined cycle systems

. Kinder Morgan explained that the steam turbines and related equipment are similar to all other steam turbines. The cooling water requirement is provided by a mechanical draft cooling tower.

**•** Kinder Morgan stated that the major wastewaters generated are boiler blowdown and cooling tower blowdown.

**•** Kinder Morgan stated that they initially added sulfuric acid to the cooling towers , but switched to alkali chemistry due to arsenic that was leaching from the pressure

treated lumber in the cooling towers . This switch allowed Kinder Morgan to meet the

POTW’s arsenic limits.
