Pollution Control Board
OF ILLINOIS
RE : Proposed Amendments to Dissolved Oxygen Standard
35 ILL
. ADM.CODE 302.206
Pollution Control Board Rule R04-25
Dear Ms Gunn
:
The Village of Addison would like to record its support for the Illinois Association of Wastewater
Agency (IAWA), petition R04-25
.
We have followed the hearings closely and feel that the evidence supports the position of the
IAWA as originally filed
. The IAWA petition would establish a dissolved oxygen water quality
standard that is protective of the states surface waters and biological resources
. We feel that the
petition is founded in good science and is attainable in the least disturbed water systems
. The
IAWA position would establish a seasonal dissolved oxygen standard that is protective of early
live stages of fish, aquatic insects and benthic organisms and establish a minimum concentration
of 3 .5 mg/L, which is more protective than suggested in the USEPA National Criteria Document
.
We do not agree with the position supported by the Illinois Department of Natural Resources and
the Illinois Environmental Protection Agency
. The agencies have not proven the case for their
proposed oxygen concentrations in surface waters
. The data show that adoption of the agency
proposed dissolved oxygen concentrations would continue a water quality standard that is
unattainable even in the least disturbed surface water systems
. We especially are opposed to the
establishment of river segments held to a different standard with out the evidence to justify such a
designation
.
We encourage the Board to adopt the IAWA petition R04-25 as filed
.
