Dear Ms. Gunn~,

Pleasereject the Illinois Association of Wastewater Agencies request to lower the

dissolved oxygen criteria from

5.0

mg/i to 3.5mg/i during the months of July though

February.

Currently, in Northern Kane County, the Fox River watershed is being stressed by

numerous factors such as fertilizer and salt run-off, low rainfall, invasion of non-native

species, altering ofwater flow from dams and the huge amount oftreated wastewater that

gets discharged into the waterway from communities all along the river.

There is an addition of several thousand new homes that are, orwill be, discharging

additional treated wastewater into Tyler Creek and Otter Creek that feed into the Fox

River.

Lowering the oxygen amount (by 30!) in this discharge will cause further disruption of

the already fragile environment.

Please consider the healthiest choice for ourwater, our environment and ultimately our

human communities. Reject the proposal to lower the dissolved oxygen standard and

continue to be a good steward ofour Illinois waterways.

Thank-you.
