Agency 167 - Pollution Control Agency
Chapter 7049 - WASTEWATER PRETREATMENT
Part 7049.0380 - CONDITIONS FOR AUTHORIZATION TO GIVE REMOVAL CREDITS
Universal Citation: MN Rules 7049.0380
Current through Register Vol. 48, No. 39, March 25, 2024
A. A POTW authority may give removal credits only if:
(1) the POTW authority applies for,
and receives, authorization from the agency to give a removal credit according
to part
7049.0450;
(2) the POTW authority demonstrates and
continues to achieve consistent removal of the pollutant according to parts
7049.0400 and
7049.0410;
(3) the POTW authority has an approved
pretreatment program according to parts
7049.0800 to
7049.1020. A POTW authority that
does not have an approved pretreatment program may, pending approval of such a
program, conditionally give removal credits as provided in part
7049.0430;
(4) the granting of removal credits will not
cause the POTW to violate the local, state, and federal sludge requirements
that apply to the sludge management method chosen by the POTW. Alternatively,
the POTW authority can demonstrate to the agency that even though it is not
presently in compliance with applicable sludge requirements, it will be in
compliance when the industrial users to whom the removal credit would apply are
required to meet their categorical pretreatment standards as modified by the
removal credit. Removal credits may be made available for the following
pollutants:
(a) for any pollutant listed in
Code of Federal Regulations, title 40, part 403, Appendix G, section I, for the
use or disposal practice employed by the POTW, when the requirements in Code of
Federal Regulations, title 40, part 503, for that practice are met;
(b) for any pollutant listed in Code of
Federal Regulations, title 40, part 403, Appendix G, section II, for the use or
disposal practice employed by the POTW when the concentration for a pollutant
listed in Appendix G, section II, in the sewage sludge that is used or disposed
does not exceed the concentration for the pollutant in Appendix G, section II;
and
(c) for any pollutant in sewage
sludge when the POTW disposes all of its sewage sludge in a municipal solid
waste landfill unit that meets the criteria in part
7035.2535; and
(5) the granting of removal
credits will not cause a violation of the POTW's national pollutant discharge
elimination system or state disposal system permit limitations or conditions.
Alternatively, the POTW authority can demonstrate to the agency that even
though it is not presently in compliance with applicable limitations and
conditions in its national pollutant discharge elimination system permit, it
will be in compliance when the industrial users to whom the removal credit
would apply are required to meet their categorical pretreatment standards, as
modified by the removal credit provision.
B. Removal credits may not be claimed when an uncontrolled overflow exists between the industrial user and the receiving POTW plant.
