Prohibited discharges.
No NPDES permit may authorize any of the discharges prohibited by
				567-62.1 (455B).
(2)
Application of effluent,
				pretreatment and water quality standards and other requirements.
Each
				NPDES permit shall include any of the following that is applicable:
a. An effluent limitation guideline
				promulgated by the administrator under Sections 301 and 304 of the Act and
				adopted by reference by the commission in
				567-62.4 (455B).
b. A standard of performance for a new source
				promulgated by the administrator under Section 306 of the Act and adopted by
				reference by the commission in
				567-62.4 (455B).
c. An effluent standard, effluent prohibition
				or pretreatment standard promulgated by the administrator under Section 307 of
				the Act and adopted by reference by the commission in
				567-62.4 (455B) or
				567-62.5(455B).
d. A water quality
				related effluent limitation established by the administrator pursuant to
				Section 302 of the Act.
e. Prior to
				promulgation by the administrator of applicable effluent and pretreatment
				standards under Sections 301, 302, 306, and 307 of the Act, such conditions as
				the director determines are necessary to carry out the provisions of the
				Act.
f. Any other limitation,
				including those:
(1) Necessary to meet water
				quality standards, treatment or pretreatment standards, or schedules of
				compliance established pursuant to any Iowa law or regulation, or to implement
				the antidegradation policy in 567-subrule 61.2(2); or
(2) Necessary to meet any other federal law
				or regulation; or
(3) Required to
				implement any applicable water quality standards; or
(4) Any legally applicable requirement
				necessary to implement total maximum daily loads established pursuant to
				Section 303(d) of the Act and incorporated in the continuing planning process
				approved under Section 303(e) of the Act and any regulations and guidelines
				issued pursuant thereto.
(5) Any
				limitation necessary to comply with the antidegradation policy requirements of
				567-subrule 61.2(2) implemented according to procedures hereby incorporated by
				reference and known as the "Iowa Antidegradation Implementation Procedure,"

.
g. Limitations must control all
				pollutants or pollutant parameters which the director determines are or may be
				discharged at a level which will cause, have the reasonable potential to cause,
				or contribute to an excursion above any water quality standard, including
				narrative criteria, in 567-Chapter 61. When the permitting authority determines
				that a discharge causes, has the reasonable potential to cause, or contributes
				to an in-stream excursion of the water quality standard for an individual
				pollutant, the permit must contain effluent limits for that
				pollutant.
h. Any more stringent
				legally applicable requirements necessary to comply with a plan approved
				pursuant to Section 208(b) of the Act.
In any case where an NPDES permit applies to effluent
				  standards and limitations described in paragraph
"a," "b," "c," "d,"
				  "e," "f," "g,"
or
"h,"
the director must state that
				  the discharge authorized by the permit will not violate applicable water
				  quality standards and must have prepared some verification of that statement.
				  In any case where an NPDES permit applies any more stringent effluent
				  limitation, described in 64.7(2)
"f"
(1) or
"g,"
based upon applicable water quality standards, a waste
				  load allocation must be prepared to ensure that the discharge authorized by the
				  permit is consistent with applicable water quality standards.
