RE: Rule Making R08-009

Dear Illinois Pollution Control Board:

We

are residents of Evanston concerned with water quality in our regional waterways. We are

writing to express our support for the recommended water quality standard improvements

proposed by the Illinois EPA for the Chicago Area Waterways (CAWS) and Lower Des Plaines

River as rule making R08-009.

These changes are long overdue and recommended only after five years of study on the CAWS

and seven on the Lower Des Plaines. We should all support the Illinois EPA's effort and approve

the changes.

As residents of the Chicago area), we think it is critical that:

•

The Metropolitan Water Reclamation District disinfect sewage treatment plant effluent to

kill bacteria and protect public health and

•

Temperature and dissolved oxygen standards be implemented to protect fish and help

them flourish.

We know that a review like this only comes along every 20 years. We strongly support the

Illinois EPA water quality standard improvements and we hope that the IPCB will too.

Thank

you,
