Dear Mr.

Therriault:

Pollution

Control

Board

The

Petition

to

Modify

Specific

Thermal

Standard

on

Coffeen

Lake during

May

and

October should

be

denied

based

on the

following

reasons:

1.

The

expansion

of the thermal

limits

does not

resolve Ameren’

s problem.

Coffeen

Lake

is

not capable

of supporting

the

cooling

demands

of Ameren

presently,

and

certainly

not in

the future.

2.

The Deer

Run

Mine

will

use water from

Lake

Lou

Yaeger

and

Glen Shoals

that

in

the past flowed

into

Shoal

Creek

which is

a

feeder stream

for Coffeen

Lake.

3. The

seven

longwall

panels

proposed

by Hillsboro

Energy

will

trap

water in the

watershed

from draining

into Coffeen

Lake.

4.

Ameren’s

desire to increase

capital

can

be

satisfied

by pursuing

alternate

energy

sources

which

will

alleviate

the

demands

on Coffeen

Lake.

5.

Alternative

energy

sources

will

also

help

to reduce the

high mercury

content

found

in surrounding

lakes.

6. Alternative

energy

sources will

also

help

address

the

carbon

emissions

issue

which

is in

the

forefront

of

legislation.

The

compromised

quality

of Coffeen

Lake

should

be

the

issue, not

the

enhanced

profits

of

Ameren. Please

deny

Ameren’s

petition

and

protect the

viability

of

Coffeen

Lake.

Thank

you for all

your efforts

in promoting

an

improved

environment.

Sincerely,

Mary

Ellen
