Sec. 11.5.
(a) If the commissioner determines that a pollutant or pollutant parameter (either conventional, nonconventional, a toxic substance, or whole effluent toxicity (WET)) is or may be discharged into the Great Lakes system at a level that will cause, have the reasonable potential to cause, or contribute to an excursion above any applicable narrative criterion or numeric water quality criterion or value under 327 IAC 2-1.5, the commissioner shall incorporate water quality-based effluent limitations (WQBELs) in an NPDES permit that will ensure compliance with the criterion or value. The commissioner shall exercise best professional judgment, taking into account the:
(1) source and nature of the
discharge;
(2) existing controls on
point and nonpoint sources of pollution;
(3) variability of the pollutant or pollutant
parameter in the effluent; and
(4)
where appropriate, dilution of the effluent in the receiving water.
In all cases, the commissioner shall use any valid, relevant, representative information pertaining to the discharge of the pollutant.
(b) If the commissioner determines that a substance is or may be discharged into the Great Lakes system at a level that will cause, have the reasonable potential to cause, or contribute to an excursion above any numeric criterion for a toxic substance contained in 327 IAC 2-1.5-8(b)(3), Table 8-1, 327 IAC 2-1.5-8(b)(5), 327 IAC 2-1.5-8(b)(6), Table 8-3, 327 IAC 2-1.5-8(b)(7), Table 8-4, 327 IAC 2-1.5-16(g), Table 16-1, a criterion for ammonia contained under 327 IAC 2-1.5-8(c)(5), a criterion for chloride, sulfate, total dissolved solids, fluoride, or dissolved iron under 327 IAC 2-1.5-8(j), or a Tier I criterion or Tier II value established under 327 IAC 2-1.5-11 through 327 IAC 2-1.5-16, the commissioner shall incorporate WQBELs in an NPDES permit for the discharge of that pollutant, and in all cases, the commissioner shall use any valid, relevant, representative information pertaining to the discharge of the substance as follows:
(1) When facility-specific effluent
monitoring data for a substance are available, the commissioner may take into
account the source and nature of the discharge, existing controls on point and
nonpoint sources of pollution, the variability of the pollutant or pollutant
parameter in the effluent, and, where appropriate, the dilution of the effluent
in the receiving water in making the determination whether to develop
preliminary effluent limitations (PELs) and comparing those effluent
limitations to the projected effluent quality (PEQ) of the discharge in
accordance with the following procedures:
(A)
The commissioner shall develop PELs for the discharge of a pollutant from a
point source using the following procedures:
(i) The commissioner shall develop
preliminary WLAs for the discharge of the pollutant from the point source to
protect human health, wildlife, acute aquatic life, and chronic aquatic life,
based upon the following:
(AA) Any existing
numeric criterion for a toxic substance contained in
327 IAC
2-1.5-8(b)(3), Table 8-1,
327 IAC
2-1.5-8(b)(5),
327 IAC
2-1.5-8(b)(6), Table 8-3,
327 IAC
2-1.5-8(b)(7), Table 8-4,
327
IAC 2-1.5-16(g), Table 16-1, or
327 IAC
2-1.5-8(c)(5) or a site-specific
modification to an existing numeric criterion established under
327
IAC 2-1.5-16.
(BB) Where there is no existing numeric
criterion, the commissioner shall calculate a Tier I criterion for such
substance for the protection of human health, wildlife, and aquatic life using
the methodologies under
327 IAC
2-1.5-11 (aquatic life),
327 IAC
2-1.5-14 (human health),
327 IAC
2-1.5-15 (wildlife), and
327
IAC 2-1.5-16 (site-specific modifications).
(CC) Where there is insufficient data to
calculate a Tier I criterion, the commissioner shall calculate a Tier II value
for such substance for the protection of human health and aquatic life using
the methodologies under
327 IAC
2-1.5-12 (aquatic life),
327 IAC
2-1.5-14 (human health), and
327
IAC 2-1.5-16 (site-specific modifications).
(DD) Where there is insufficient data to
calculate a Tier II value, the commissioner shall apply the procedure in
subdivision (3) to determine whether data must be generated to calculate a Tier
II value.
(ii) The
commissioner shall develop a preliminary WLA for the discharge of chloride,
sulfate, total dissolved solids, fluoride, or dissolved iron, in addition to
the preliminary WLAs developed for the parameter under item (i), based on the
numeric criterion for the substance under
327 IAC
2-1.5-8(j) when
applicable.
(iii) Section 11.4(c)
of this rule shall be used as the basis for determining preliminary WLAs in
accordance with items (i) and (ii).
(iv) The commissioner shall use the
preliminary WLAs developed under items (i) through (iii) to develop monthly and
daily PELs in accordance with the procedure for converting WLAs into WQBELs
under section 11.6(c) of this rule.
(B) The commissioner shall determine the PEQ
as follows:
(i) When monthly average data are
available, calculated using at least two (2) data points over the period of a
month, the monthly PEQ shall be determined as follows:
(AA) The commissioner shall identify the
number of monthly averages of the effluent data and the coefficient of
variation of the monthly averages of the effluent data.
(BB) The commissioner shall obtain the
appropriate multiplying factor from subsection (h) based on the information
obtained in subitem (AA).
(CC) The
maximum of the monthly average values shall be multiplied by the multiplying
factor determined under subitem (BB) to determine the monthly PEQ.
(ii) When monthly average data are
not available, the monthly PEQ shall be identical to the daily PEQ determined
under item (iii). An alternate method of calculating monthly averages may be
used if the applicant demonstrates that this alternate method results in
monthly averages representative of actual conditions at the facility. Monthly
averages calculated under this item shall be used to determine the monthly PEQ
using the procedure in item (i).
(iii) The daily PEQ shall be determined as
follows:
(AA) The commissioner shall identify
the number of daily effluent samples and the coefficient of variation of the
daily effluent samples.
(BB) The
commissioner shall obtain the appropriate multiplying factor from subsection
(h) based on the information obtained in subitem (AA).
(CC) The maximum of the daily effluent
samples shall be multiplied by the multiplying factor determined under subitem
(BB) to determine the daily PEQ.
(iv) The coefficient of variation shall be
calculated as the ratio of the standard deviation of the daily or monthly
effluent data divided by the arithmetic average of the effluent data, except
that where there are fewer than ten (10) data points the coefficient of
variation shall be specified as six-tenths (0.6).
(v) In lieu of the procedures under items (i)
through (iv), the commissioner shall allow the use of an alternate procedure
for the determination of the PEQ if the applicant demonstrates that the
alternate statistical procedure meets the following:
(AA) Is a scientifically defensible
statistical method.
(BB) Specifies
the daily PEQ as the ninety-fifth percentile of the distribution of the
projected population of daily values of the facility-specific effluent
monitoring data.
(CC) Specifies the
monthly PEQ as the ninety-fifth percentile of the distribution of the projected
population of monthly average values of the facility-specific effluent
monitoring data.
(DD) Accounts for
and captures the long term daily and monthly variability of the effluent
quality.
(EE) Accounts for
limitations associated with sparse data sets.
(FF) Assumes a lognormal distribution of the
facility-specific effluent data unless otherwise shown by the effluent data
set.
(C) The
commissioner shall establish WQBELs in the NPDES permit for each substance
that:
(i) the monthly PEQ developed under
clause (B) exceeds the monthly PEL developed under clause (A); or
(ii) the daily PEQ developed under clause (B)
exceeds the daily PEL developed under clause (A).
(D) If facility-specific effluent monitoring
data for a metal are available in the form of dissolved metal and the PELs for
the metal developed under clause (A) are based on an acute or chronic aquatic
life water quality criterion or value expressed in the form of dissolved metal,
the commissioner shall make the determination under clause (C) using PEQs and
PELs in the form of dissolved metal if the following conditions are satisfied:
(i) The discharger provides an acceptable
site-specific study that shows that the metal in the effluent does not become
more dissolved in the receiving waterbody outside the mixing zone.
(ii) Representative data are available from
the receiving waterbody to calculate the background concentration of the metal
in accordance with section 11.4(a)(8) of this rule and, if applicable, the
hardness of the receiving waterbody in accordance with section 11.4(a)(13) of
this rule.
(iii) The
facility-specific effluent monitoring data in the form of dissolved metal are
representative of the magnitude and variability of the metal in the
effluent.
(iv) The PEQs in the form
of dissolved metal are determined under clause (B) using the effluent
monitoring data in item (iii).
(v)
The PELs in the form of dissolved metal are developed as follows:
(AA) Preliminary WLAs in the form of
dissolved metal are developed consistent with section 11.4(c) of this rule and
using the receiving waterbody data in item (ii) to protect acute and chronic
aquatic life.
(BB) The preliminary
WLAs in subitem (AA) are used to develop monthly and daily PELs in accordance
with section 11.6(c) of this rule.
(vi) A determination under clause (C) using
PEQs and PELs developed under this item in the form of total recoverable metal
shows that the commissioner is not required to establish WQBELs in the NPDES
permit for the metal. The PEQs and PELs shall be developed as follows:
(AA) PEQs in the form of total recoverable
metal shall be determined under clause (B) using facility-specific effluent
monitoring data in the form of total recoverable metal that is comparable to
the data in item (iii).
(BB)
Monthly and daily PELs in the form of total recoverable metal shall be
developed using preliminary WLAs developed under section 11.4(c) of this rule
for all the applicable criteria and values for the metal that are expressed in
the form of total recoverable metal and in accordance with section 11.6(c) of
this rule. The preliminary WLAs shall be calculated using the receiving
waterbody data in item (ii).
(2) When facility-specific effluent
monitoring data for a substance are not available, the commissioner shall
exercise best professional judgment, taking into account the source and nature
of the discharge, existing controls on point and nonpoint sources of pollution,
and, where appropriate, the dilution of the effluent in the receiving water:
(A) for a new Great Lakes discharger, to
develop an estimated monthly and daily PEQ necessary to make a determination
under this subsection; or
(B) for
an existing Great Lakes discharger, to determine whether it is necessary to
require the applicant to collect the data required to make a determination
under this subsection.
(3) The commissioner shall develop the
necessary data to calculate Tier II values where such data does not currently
exist as follows:
(A) Except as provided in
clauses (B) and (D) or subdivision (4), for each toxic substance that a
permittee reports as known or believed to be present in its effluent, or that
the commissioner reasonably believes may be present in the effluent, and for
which pollutant data sufficient to calculate Tier II values for noncancer human
health, acute aquatic life, or chronic aquatic life do not exist, the
commissioner shall take the following actions:
(i) For those effects (noncancer human
health, acute aquatic life, or chronic aquatic life) for which sufficient data
do not exist, the commissioner shall use all available, relevant information,
including QSAR information and other relevant toxicity information, to estimate
ambient screening values for such pollutant that will protect humans from
health effects other than cancer, and aquatic life from acute and chronic
effects.
(ii) Using the procedures
under subdivision (1), the commissioner shall develop PELs for the discharge of
the pollutant from the point source to protect human health, acute aquatic
life, and chronic aquatic life based upon the estimated ambient screening
values.
(iii) The commissioner
shall compare the PEQs developed according to the procedures under subdivision
(1) to the PELs developed under item (ii). If the monthly or daily PEQ exceeds
the respective monthly or daily PEL, the commissioner shall generate or require
the permittee to generate the data necessary to derive Tier II values for
noncancer human health, acute aquatic life, and chronic aquatic life.
(iv) The data generated under item (iii)
shall be used in calculating a Tier II value as required under subdivision (1).
The calculated Tier II value shall be used in calculating the PELs under
subdivision (1). These PELs shall be used for purposes of determining whether a
WQBEL must be included in the permit under subdivision (1).
(B) With the exception of BCCs,
the commissioner is not required to apply the procedures under clause (A) or
include WQBELs to protect aquatic life for any pollutant discharged by an
existing point source into the Great Lakes system if the following occur:
(i) There is insufficient data to calculate a
Tier I criterion or Tier II value for aquatic life for the pollutant.
(ii) The permittee has demonstrated that the
whole effluent does not exhibit acute or chronic toxicity.
(iii) The permittee has demonstrated, through
a biological assessment, that there are no acute or chronic effects on aquatic
life in the receiving water.
(C) Nothing in clause (A) or (B) shall
preclude or deny the right of the commissioner to:
(i) determine, in the absence of the data
necessary to derive a Tier II value, that the discharge of the pollutant will
cause, have the reasonable potential to cause, or contribute to an excursion
above a narrative criterion for water quality; and
(ii) incorporate a WQBEL for the pollutant
into an NPDES permit.
(D) If the commissioner develops a WQBEL
consistent with clause (C) that is at least as stringent as a WQBEL that would
have been developed based upon the Tier II value or values for that pollutant,
the commissioner may require the permittee to generate the data necessary to
derive a Tier II value or values for that pollutant.
(4) The determinations under this subdivision
shall be made on a pollutant-by-pollutant, outfall-by-outfall basis. This
subdivision applies only in the absence of an EPA-approved TMDL applicable to
the discharge or in the absence of an assessment and remediation plan submitted
and approved in accordance with section 11.4(a)(2) of this rule. The following
procedures shall be used in the consideration of intake pollutants in
determining reasonable potential:
(A) As used
in this subdivision and section 11.6(i) of this rule, "intake pollutant" means
a pollutant that is present in waters of the state at the time it is withdrawn
from such waters by the discharger or other facility, such as a public water
system supplying the discharger with intake water.
(B) As used in this subdivision, subsection
(g), and section 11.6(i) of this rule, an intake pollutant is considered to be
from the same body of water as the discharge if the following conditions exist:
(i) The commissioner finds that the intake
pollutant would have reached the vicinity of the outfall point in the receiving
water within a reasonable period had it not been removed by the permittee. This
finding may be deemed established if:
(AA)
the representative background concentration of the pollutant in the receiving
water, as determined under section 11.4(a)(8) of this rule, (excluding any
amount of the pollutant in the facility's discharge) is similar to or greater
than that in the intake water;
(BB)
there is a direct hydrological connection between the intake and discharge
points (the water at the point of intake naturally flows toward the water at
the point of discharge); and
(CC)
any difference in a water quality characteristic (such as temperature, pH, and
hardness) between the intake and receiving waters does not result in an adverse
impact on the receiving water.
(ii) The commissioner may also consider other
site-specific factors relevant to the transport and fate of the pollutant to
make the finding in a particular case that a pollutant would or would not have
reached the vicinity of the outfall point in the receiving water within a
reasonable period had it not been removed by the permittee.
(iii) An intake pollutant from ground water
may be considered to be from the same body of water if the commissioner
determines that the pollutant would have reached the vicinity of the outfall
point in the receiving water within a reasonable period had it not been removed
by the permittee, except that such a pollutant is not from the same body of
water to the extent that the ground water contains the pollutant partially or
entirely due to human activity, such as industrial, commercial, or municipal
operations, disposal actions, or treatment processes.
(iv) Notwithstanding any other provision in
this clause, an intake pollutant shall be considered to be from the same body
of water if the permittee's intake point is located on Lake Michigan and the
outfall point is located on a tributary of Lake Michigan and the following
conditions are met:
(AA) The representative
background concentration of the pollutant in the receiving water, as determined
under section 11.4(a)(8) of this rule (excluding any amount of the pollutant in
the facility's discharge) is similar to or greater than that in the intake
water.
(BB) Any difference in a
water quality characteristic (such as temperature, pH, and hardness) between
the intake and receiving waters does not result in an adverse impact on the
receiving water.
(C) The
commissioner may use the procedure to determine reasonable potential described
in this subdivision in lieu of the procedures contained under subdivisions (1)
through (3) provided the following conditions are met:
(i) The commissioner may determine that there
is no reasonable potential for the discharge of an intake pollutant or
pollutant parameter to cause or contribute to an excursion above a narrative
criterion or numeric water quality criterion or value under 327 IAC 2-1.5 when
a discharger demonstrates to the satisfaction of the commissioner (based upon
information provided in the permit application or other information deemed
necessary by the commissioner) that:
(AA) the
facility does not contribute any additional mass of the intake pollutant to its
wastewater;
(BB) the facility
withdraws one hundred percent (100%) of the intake water containing the
pollutant from the same body of water into which the discharge is
made;
(CC) the facility does not
alter the intake pollutant chemically or physically in a manner that would
cause adverse water quality impacts to occur that would not occur if the
pollutants were left in-stream;
(DD) the facility does not cause an increase
in the intake pollutant concentration at the edge of the mixing zone, or at the
point of discharge if a mixing zone is not allowed, as compared to the
pollutant concentration in the intake waterbody unless the increased
concentration does not cause or contribute to an excursion above an applicable
narrative criterion or numeric water quality criterion or value; and
(EE) the timing and location of the discharge
would not cause adverse water quality impacts to occur that would not occur if
the intake pollutant were left in the waterbody.
(ii) If a discharge of an intake pollutant or
pollutant parameter is not able to qualify under item (i), the commissioner may
decide not to impose WQBELs on the discharge, if the following conditions are
met:
(AA) The discharge consists of one (1)
or more internal wastestreams that do qualify (qualifying wastestreams) under
item (i) and one (1) or more internal wastestreams that do not qualify
(nonqualifying wastestreams) under item (i).
(BB) For nonqualifying wastestreams composed
entirely of storm water, the permittee accepts permit conditions for the storm
water wastestream that the commissioner determines to be necessary to protect
the water quality of the receiving waterbody. The requirements imposed shall be
as if the storm water wastestream discharged directly into the receiving
waterbody and shall be consistent with requirements imposed on other similar
storm water discharges to the waterbody.
(CC) For nonqualifying wastestreams not
composed entirely of storm water, the permittee accepts WQBELs on each of the
nonqualifying wastestreams that have a reasonable potential for the discharge
of the intake pollutant or pollutant parameter to cause or contribute to an
excursion above a narrative criterion or numeric water quality criterion or
value as determined using the procedures under subdivisions (1) through (3).
For purposes of determining reasonable potential and developing WQBELs for
these nonqualifying wastestreams, the preliminary WLAs and WLAs in the absence
of a TMDL shall be determined as if these nonqualifying wastestreams discharged
directly into the receiving waterbody without combining with the qualifying
wastestreams.
(iii) Upon
a finding under item (i) or (ii) that a pollutant in the discharge does not
cause, have the reasonable potential to cause, or contribute to an excursion
above an applicable narrative criterion or numeric water quality criterion or
value, the commissioner is not required to include a WQBEL in the facility's
permit for the intake pollutant provided:
(AA) the NPDES permit fact sheet or statement
of basis includes a specific determination that there is no reasonable
potential for the discharge of an intake pollutant to cause or contribute to an
excursion above an applicable narrative criterion or numeric water quality
criterion or value and references appropriate supporting documentation included
in the administrative record;
(BB)
the permit requires all influent, effluent, and ambient monitoring necessary to
demonstrate that the conditions in item (i) or (ii) are maintained during the
permit term; and
(CC) the permit
contains a reopener clause authorizing modification or revocation and
reissuance of the permit if new information indicates changes in the conditions
under item (i) or (ii).
(iv) Absent a finding under item (i) or (ii)
that the discharge of an intake pollutant or pollutant parameter does not
cause, have the reasonable potential to cause, or contribute to an excursion
above an applicable narrative criterion or numeric water quality criterion or
value, the commissioner shall use the procedures contained under subdivisions
(1) through (3) to determine whether the discharge of that pollutant causes,
has the reasonable potential to cause, or contribute to an excursion above an
applicable narrative criterion or numeric water quality criterion or
value.
(5) Notwithstanding this subsection, if the
commissioner determines that the geometric mean of a pollutant in fish tissue
samples collected from a waterbody exceeds the tissue basis of a water quality
criterion or value, after consideration of the variability of the pollutant's
bioconcentration and bioaccumulation in fish, the following provisions apply:
(A) If such pollutant is a BCC, each facility
that discharges detectable levels of the BCC to that water has the reasonable
potential to cause or contribute to an excursion above a water quality
criterion or value for that BCC and the commissioner shall establish a WQBEL
for such pollutant in the NPDES permit for each such facility.
(B) If such pollutant is not a BCC, the
commissioner may determine that any or all of the facilities that discharge
detectable levels of the pollutant to that water have the reasonable potential
to cause or contribute to an excursion above a water quality criterion or value
for that pollutant and the commissioner shall establish a WQBEL for such
pollutant in the NPDES permit for each such facility.
(c) Except as provided in subdivision (3), where the commissioner determines that the WET of an effluent is or may be discharged at a level that will cause, have the reasonable potential to cause, or contribute to an excursion above any numeric interpretation of a narrative WET criterion contained in 327 IAC 2-1.5-8, the commissioner shall incorporate WQBELs for WET in the NPDES permit and in all cases, the commissioner shall use any valid, relevant, or representative information pertaining to the discharge of WET as follows:
(1) When facility-specific WET data
are available, the commissioner may take into account the source and nature of
the discharge, existing controls on point and nonpoint sources of pollution,
the variability of the WET in the effluent, and, where appropriate, the
dilution of the effluent in the receiving water in making the determination to
develop effluent limitations for WET. The WET of an effluent is or may be
discharged at a level that will cause, have the reasonable potential to cause,
or contribute to an excursion above any applicable WET criterion contained
under 327 IAC 2-1.5, when effluent-specific information demonstrates the
following:
(A) The acute WET of an effluent
is or may be discharged at a level that will cause, have the reasonable
potential to cause, or contribute to an excursion above an applicable acute WET
criterion applied to the undiluted discharge, when effluent-specific
information demonstrates the following:
(TUa)(F) > 0.2
| Where: | TUa | = | The geometric mean of the measured acute toxicity values expressed in acute toxic units (TUa or TUc). Individual toxicity values may be estimated for the missing endpoint using a default ACR of ten (10), when data exist for chronic WET, but not for acute WET. |
| F | = | Fraction of the measured toxicity values greater than the preliminary WLA for acute WET determined under section 11.4(c) of this rule (fraction failed). |
(B)
The acute WET of an effluent is or may be discharged at a level that will
cause, have the reasonable potential to cause, or contribute to an excursion
above an applicable acute WET criterion applied outside an alternate mixing
zone, when effluent-specific information demonstrates the following:
F > 0.2
| Where: | F | = | Fraction of the measured toxicity values greater than the preliminary WLA for acute WET determined under section 11.4(c) of this rule (fraction failed). Individual toxicity values may be estimated for the missing endpoint using a default ACR of ten (10), when data exist for chronic WET, but not for acute WET. |
(C)
The chronic WET of an effluent is or may be discharged at a level that will
cause, have the reasonable potential to cause, or contribute to an excursion
above an applicable chronic WET criterion, when effluent-specific information
demonstrates the following:
| Where: | TUc | = | The geometric mean of the measured chronic toxicity values expressed in chronic toxic units. Individual toxicity values may be estimated for the missing endpoint using a default ACR of ten (10), when data exist for acute WET, but not for chronic WET. |
| Qe | = | The effluent flow rate as determined under section 11.4(a)(9) of this rule. | |
| Qw | = | The portion of the receiving waterbody allocated for mixing as determined under section 11.4(b) of this rule. | |
| F | = | Fraction of the measured toxicity values greater than the preliminary WLA for acute or chronic WET determined under section 11.4(c) of this rule (fraction failed). |
(2) When WET data are not available, the
commissioner shall exercise best professional judgment, taking into account the
source and nature of the discharge, existing controls on point and nonpoint
sources of pollution, and, where appropriate, the dilution of the effluent in
the receiving water to determine whether it is necessary to impose WET
requirements in accordance with the following:
(A) For a new Great Lakes discharger, the
commissioner shall determine whether it is necessary to impose WET
limitations.
(B) For an existing
Great Lakes discharger, whether it is necessary to require the applicant to
collect the data required to make a determination under this subsection. The
commissioner may include in the NPDES permit the following conditions to
generate additional data and control toxicity if found:
(i) WET testing requirements to generate the
data needed to adequately characterize the toxicity of the effluent to aquatic
life.
(ii) A toxicity reduction
evaluation and a schedule to comply with WET limits if any toxicity testing
data indicate that the WET of an effluent is or may be discharged at levels
that will cause, have the reasonable potential to cause, or contribute to an
excursion above any applicable WET criterion.
(iii) WET limits that become effective upon
completion of the compliance schedule.
(3) Limitations on WET are not necessary
where the commissioner demonstrates in the fact sheet or briefing memo of the
NPDES permit that chemical-specific limits for the effluent are sufficient to
attain and maintain the applicable narrative water quality criteria for
WET.
(d) Once the commissioner has determined in accordance with this section that a WQBEL must be included in an NPDES permit, the commissioner shall do the following:
(1) Rely upon the WLA established for the
point source either as part of any EPA-approved TMDL prepared under section
11.4 of this rule, or as part of an assessment and remediation plan developed
and approved in accordance with section 11.4(a)(2) of this rule, or, in the
absence of such TMDL or plan, calculate WLAs for the protection of acute and
chronic aquatic life, wildlife, and human health in accordance with the
provisions for developing WLAs under section 11.4 of this rule.
(2) Develop WQBELs using these WLAs in
accordance with section 11.6 of this rule.
(e) The commissioner may require monitoring for a pollutant or pollutant parameter even if it is determined that a WQBEL in the NPDES permit for that pollutant or pollutant parameter is not required.
(f) In addition to this section, effluent limitations shall be established to comply with all other applicable state and federal laws and regulations, including technology-based requirements and antidegradation policies.
(g) Notwithstanding subsection (b) or (c) and only in situations where the intake and outfall points are located on the same body of water as defined in subsection (b)(4)(B), the commissioner shall not impose WQBELs for a discharge consisting solely of once-through noncontact cooling water, except in accordance with the following:
(1) The commissioner may require a WQBEL
based on an acute aquatic life criterion or value for a substance or acute WET
when information is available indicating that such a limit is necessary to
protect aquatic life unless the discharger is able to demonstrate that the
presence of the substance or WET is due solely to its presence in the intake
water.
(2) The commissioner shall
establish limitations or other requirements in the permit for the noncontact
cooling water wastestream to prevent impairment of the receiving waterbody if a
valid biological assessment of the receiving waterbody indicates that the
noncontact cooling water discharge impairs an existing or designated use of the
waterbody, exclusive of thermal impacts from a discharge for which alternative
thermal effluent limitations have been established in accordance with Section
316(a) of the CWA and 327 IAC 5-7.
(3) If a substance is present at elevated
levels in the noncontact cooling water wastestream due to improper operation or
maintenance of the cooling system, and this substance is or may be discharged
at a level that will cause, have the reasonable potential to cause, or
contribute to an excursion above a numeric criterion or value for a toxic
substance as determined under subsection (b), WQBELs shall be established using
the procedures in sections 11.4 and 11.6 of this rule.
(4) If the permittee uses or proposes to use
additives in the noncontact cooling water wastestream, the additives shall be
evaluated using the reasonable potential procedures contained under this
section to determine whether WQBELs are necessary for the
wastestream.
(5) If the source of
the noncontact cooling water wastestream is contaminated ground water, this
subsection does not apply to the discharge of the substances contaminating the
ground water.
(6) If one (1) or
more wastestreams consisting solely of noncontact cooling water are combined
with one (1) or more wastestreams not consisting solely of noncontact cooling
water, this subsection may still be applied to the wastestreams consisting
solely of noncontact cooling water if, for the wastestreams that do not consist
solely of noncontact cooling water, the following requirements are imposed:
(A) For each of the wastestreams composed
entirely of storm water, permit conditions that the commissioner determines to
be necessary to protect the water quality of the receiving waterbody shall be
imposed. The requirements imposed shall be as if the storm water wastestream
discharged directly into the receiving waterbody and shall be consistent with
requirements imposed on other similar storm water discharges to the
waterbody.
(B) For each of the
wastestreams not composed entirely of storm water, each wastestream shall be
evaluated to determine if there is a reasonable potential for the discharge of
a pollutant or pollutant parameter to cause or contribute to an excursion above
a narrative criterion or numeric water quality criterion or value as determined
using the procedures in this section. For purposes of determining reasonable
potential and developing WQBELs for these wastestreams, the preliminary WLAs
and WLAs in the absence of a TMDL shall be determined as if these wastestreams
discharged directly into the receiving waterbody without combining with the
wastestreams consisting solely of noncontact cooling water.
(7) As used in this subsection,
"once-through noncontact cooling water" means water used for cooling that does
not come into direct contact with any raw material, intermediate product, final
product, or waste product and makes one (1) or two (2) passes for the purpose
of removing waste heat.
(h) The multiplying factors to be used in subsection (b) are established in Tables 11.5-1 and 11.5-2 and shall be obtained as follows:
(1) Round the
coefficient of variation (CV) identified in subsection (b) to the nearest CV in
Table 11.5-1 or Table 11.5-2. If the CV identified in subsection (b) is greater
than two (2.0), set the CV equal to two (2.0).
(2) Obtain the appropriate multiplying factor
from Table 11.5-1 or Table 11.5-2 using the number of samples identified in
subsection (b) and the CV determined under subdivision (1). If the number of
samples identified under subsection (b) is greater than one hundred (100),
obtain the multiplying factor using one hundred (100) samples.
