Iowa Admin. Code r. 567-62.4 - Effluent limitations or pretreatment requirements more stringent than the effluent or pretreatment standards
(1)
Effluent limitations necessary to
meet water quality standards (WQSs). No effluent, alone or in
combination with the effluent of other sources, shall cause a violation of any
applicable WQS. When it is found that a discharge that would comply with
applicable effluent standards or effluent limitations in this chapter would
cause a violation of WQSs, the discharge will be required to meet the water
quality-based effluent limits (WQBELs) necessary to achieve the applicable WQSs
as established in 567-Chapter 61. WQBELs shall be derived from a wasteload
allocation (WLA) calculated for the discharge, as described in the Iowa
Wasteload Allocation Procedure (WLAP) (Nov. 11, 2020), or a WLA calculated for
a TMDL, whichever is more stringent, except that the daily sample maximum
criteria forE. coli set forth in 567-Chapter 61 shall not be
used as an end-of-pipe permit limitation.
(2)
Pretreatment requirements more
stringent than categorical standards. The department or POTW may
impose pretreatment requirements more stringent than the applicable categorical
standards in 62.3(1) when more stringent requirements are necessary to prevent
violations of WQSs, pass through, acute worker health or safety problems, or
interference (including inhibiting or disrupting sludge use and disposal
practices).
(3)
Effluent
limitations for pollutants not covered by effluent or categorical
standards. When a pollutant is not otherwise regulated under rules
567-62.2 (455B) and
567-62.3 (455B), effluent limits
or pretreatment requirements may be imposed on a case-by-case basis.
a. Effluent limits shall be based on the
effect of the pollutant in water and the feasibility and reasonableness of
treating the pollutant.
b.
Pretreatment requirements shall be based on the effect of the pollutant in
water, the effect on the receiving treatment works (including pass through,
inhibition, worker safety, and sludge disposal), and the feasibility and
reasonableness of treating the pollutant.
