Sec. 2.
(a) A user of
a POTW, whether or not the user is subject to national categorical standards or
state, local, or any other national pretreatment standard or requirement, shall
not allow the introduction of the following into the POTW:
(1) A pollutant from any source of
nondomestic wastewaters that could pass through or cause interference with the
operation or performance of the POTW.
(2) A pollutant that could create a fire or
explosion hazard in the POTW, including waste streams with a closed cup
flashpoint of less than one hundred forty (140) degrees Fahrenheit (sixty (60)
degrees Celsius) using the test methods in
40 CFR
261.21.
(3) A pollutant that could cause corrosive
structural damage to the POTW, including a discharge with pH lower than 5.0,
unless the POTW is specifically designed to accommodate such a
discharge.
(4) A solid or viscous
pollutant in an amount that could cause obstruction to the flow in a sewer or
other interference with the operation of the POTW.
(5) A pollutant, including an oxygen
demanding pollutant (such as biochemical oxygen demand) released in a discharge
at a flow rate or pollutant concentration that could cause interference in the
POTW.
(6) Heat in an amount that
could:
(A) inhibit biological activity in the
POTW and result in interference or damage to the POTW; or
(B) exceed forty (40) degrees Celsius or one
hundred four (104) degrees Fahrenheit at the POTW treatment plant unless the
commissioner, upon request of the POTW, approves alternate temperature
limits.
(7) Petroleum,
oil, nonbiodegradable cutting oil, or products of mineral oil origin in an
amount that could cause interference or pass through.
(8) A pollutant that could result in the
presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems.
(9) A trucked or hauled pollutant, except:
(A) with the permission of the POTW;
and
(B) when introduced to the POTW
at a discharge point designated by the POTW.
(b) Specific limits on the prohibited
substances listed in subsection (a) must:
(1)
be developed and effectively enforced by a POTW required to develop a POTW
pretreatment program under
40
CFR 403.8 and 327 IAC 5-19;
(2) continue to be developed, as necessary,
and effectively enforced by a POTW with an approved POTW pretreatment program;
or
(3) be developed and enforced by
a POTW, not included in subdivision (1) or (2), so as to limit:
(A) a pollutant contributed by an industrial
user that has caused or is likely to cause interference or pass through at the
receiving POTW; and
(B) the
recurrence of the contributed pollutant's affect on the POTW.
A POTW affected by this subdivision shall make appropriate
changes in the POTW treatment facilities or operation, as necessary, to prevent
occurrences of interference or pass through. Individual notice shall be made in
writing to persons or groups who have requested to be notified and given an
opportunity to comment about the development and enforcement of specific
effluent limits as required by this subsection.
(c) POTWs may develop BMPs to
implement subsection (b)(1) and (b)(2). Such BMPs shall be considered local
limits and pretreatment standards for the purposes of Section 307(d) of the
Clean Water Act (
33 U.S.C.
1317(d)) .
(d) When specific prohibitions or limits on
pollutants or pollutant parameters are developed by a POTW in accordance with
subsection (b) or (c), the prohibitions or limits are pretreatment standards
for the purposes of the pretreatment rules and Section 307(d) of the Clean
Water Act (
33 U.S.C.
1317(d)) .
