RE:

Proposed Amendments to Dissolved Oxygen Standard

35 ILL. ADM.CODE 302 .206

Pollution Control Board Rule R04-25

Dear Ms Gunn:

The Greater Peoria Sanitary District encourages your favorable consideration of the

Illinois Association of Wastewater Agency (IAWA) petition R04-25 regarding dissolved

oxygen standards. Adoption of the IAWA petition will establish a dissolved oxygen

water quality standard that fundamentally protects and enhances the aquatic life in our

states waters while balancing sewage treatment costs borne by our local economy .

IAWA has consistently supported sound science as the basis for establishing rules and

regulations . While we understand and respect the mission of the Illinois Department of

Natural Resources and the Illinois Environmental Protection Agency, in this case we

conclude the position adopted by IEPA would result in an unattainable and unnecessary

water quality standard . The record shows IAWA has documented numerous stream

segments unimpaired by urban development that sustain the highest orders of life stages

while not meeting the proposed IEPA dissolved oxygen concentrations .

IAWA Petition R04-25 is responsive and responsible to the citizens of the State of

Illinois. We encourage the Board to adopt the petition .

Sincerely,

GREATER PEORIA SANITARY DISTRICT
