35 Ill. Adm. Code 602.500
Other Aquatic Pesticide Permit Requirement
Section 602.500 Other Aquatic
Pesticide Permit Requirement
a) When the application of the
pesticide will have an effect on any community water supply, a person must not
apply an aquatic pesticide, other than an algicide, copper sulfate, a copper sulfate-based
product, or a copper sulfate chemical aid, to any stream, reservoir, lake, pond,
or other body of water used as a community water supply source without an
Aquatic Pesticide Permit issued by the Agency. Effect means any measurable
concentration of the pesticide in the intake water of the community water
supply.
b) A person must not apply an
aquatic pesticide, other than an algicide, copper sulfate, a copper sulfate-based
product, or a copper sulfate chemical aid, within 20 miles upstream of a public
or food processing water supply intake without an Aquatic Pesticide Permit
issued by the Agency. The 20-mile upstream distance must be measured as
follows:
1) for streams, the distance must
be measured from the water supply intake to the downstream edge of the
application area;
2) for impoundments, the distance
must be measured as the straight-line distance over water from the intake to
the nearest edge of the application area or, if the shape of the impoundment
will not allow a straight-line measurement over water, the distance must be
measured as the shortest distance over water between the intake and the
application area; and
3) for streams tributary to
impoundments, the distance must be the sum of the stream distance plus the
shortest line distance described in subsection (b)(2).
