35 Ill. Adm. Code 104.565
Opinion and Order
Section 104.565
Opinion and Order
a) When the Board adopts a
TLWQS
, the Board will maintain,
in its water quality standards, the underlying designated use and criterion
addressed by the
TLWQS
, unless the Board
adopts and USEPA approves a revision to the underlying designated use and
criterion consistent with 40 CFR 131.10 and 131.11.
b) A
TLWQS
will not be
adopted if the designated use and criterion addressed by the
TLWQS
can be achieved
by implementing technology based effluent limits required under sections 301(b)
and 306 of the Clean Water Act and 35 Ill. Adm. Code 304.
c) The Board will not adopt
a
TLWQS
if the petitioner
fails to make its demonstration as set forth in Section 104.560.
d) All orders adopting a
TLWQS
will include:
1) Identification of the pollutant or water
quality parameter;
2) Applicability
A) Watershed, Water Body,
Waterbody Segment and Multiple Discharger
i) Identification of the
watershed, water body, or waterbody segment to which the
TLWQS
applies;
ii) Eligibility criteria
that may be used by new or existing dischargers or classes of dischargers to
obtain coverage under the
TLWQS
during its duration; and
iii) The list of persons
covered under the
TLWQS
at the time of
the Board's adoption.
B) Single Discharger
i) Identification of the
water body or waterbody segment to which the
TLWQS applies
; and
ii) The person covered
under the
TLWQS
.
3) The
TLWQS
requirements and
conditions that apply throughout the term of the
TLWQS
:
A) Will represent the
highest attainable condition of the watershed, water body, or waterbody segment
applicable throughout the term of the
TLWQS
based on petitioner's demonstration
required by Section 104.560; and
B) Will not result in any
lowering of the currently attained ambient water quality, unless the petitioner
demonstrates that a
TLWQS
is necessary for
restoration activities under Section 104.560(a)(7).
4) The highest attainable
condition of the water body or waterbody segment as a quantifiable expression
of one of the following:
A) For a single discharger
and a multiple discharger
TLWQS
:
i) The highest attainable interim criterion;
ii) The interim effluent
condition that reflects the greatest pollutant reduction achievable; or
iii) If no additional
feasible pollutant control technology can be identified, the interim criterion
or interim effluent condition that reflects the greatest pollutant reduction
achievable with the pollutant control technologies installed at the time the
Board adopts the
TLWQS
and with the
adoption and implementation of a Pollutant Minimization Program.
B) For a
TLWQS
applicable to a
watershed, water body, or waterbody segment:
i) The highest attainable interim use and
interim criterion; or
ii) If no additional
feasible pollutant control technology can be identified, the interim use and
interim criterion that reflect the greatest pollutant reduction achievable with
the pollutant control technologies installed at the time the Board adopts the
TLWQS
and with the
adoption and implementation of a Pollutant Minimization Program.
5) A statement providing
that the requirements of the
TLWQS
are either the highest attainable condition identified
at the time of the adoption of the
TLWQS
, or the highest attainable condition
later identified during any re-evaluation consistent with Section 104.580,
whichever is more stringent.
6) The term of the
TLWQS
, expressed as an
interval of time from the date of USEPA approval or a specific date.
7) For a
TLWQS
with a term
greater than five years, a specified frequency to re-evaluate the highest
attainable condition under Section 104.580. The re-evaluation must occur no
less frequently than every five years after both the Board and USEPA approve the
TLWQS
.
8) A provision that the
TLWQS
will no longer be
the applicable water quality standard for purposes of the Clean Water Act if the
petitioner does not conduct a re-evaluation consistent with the frequency
specified in the
TLWQS
or the results
are not submitted to USEPA as required by Section 104.580.
e) The Board order adopting
or declining to adopt a
TLWQS
is a
final order. Any participant may file a motion for reconsideration, under 35
Ill. Adm. Code 101.520, of a final Board order entered under this Section.
