(iv) Standards For Surface Waters In Wetlands
(A) Tributary wetlands to which the interim classifications referenced in
section 31.13(1)(e)(iv) apply, shall be subject to the following interim
standard:
(1) Until such time as the Commission adopts site-specific standards
for the tributary wetland, water quality in the wetland shall be
maintained for each parameter at whichever of the following levels
is less restrictive:
(a) ambient quality, or
(b) that quality which meets the numeric standards (except for
numeric standards for pH, dissolved oxygen, and any
standard established for the protection of a domestic water
supply use) of the tributaries of the surface water segment to
which the wetland is most directly hydrologically connected.
Where the applicable numeric standard is based on section
31.16, table III, of this regulation, the numeric standard
applicable to the wetland may be implemented taking into
account the water effect ratio of the pollutant.
(2) Ambient quality shall be determined in accordance with section
31.7(1}(b}(ii) and shall take into account the location, sampling
date, and quality of all available data. Ambient quality shall be
determined as of the time the first regulatory action is undertaken
which requires the identification of water quality standards for
wetlands. If available information is not adequate to otherwise
determine or estimate ambient quality, the interim standard set
forth in section 31.7(1) (b) (iv) (A) (1) (b) shall apply.
(B) Wetlands for which the Commission has adopted asite-specific
"wetlands" classification described in section 31.13(1)(e)(v), shall be
subject to numeric standards and designations adopted by the
Commission. The Commission shall adopt any numeric standards and
designations determined to be appropriate in view of the functions and
values to be protected for the wetlands in question.
(C) Created wetlands, shall be subject only to the narrative standards set
forth in section 31.11, unless the Commission has adopted the wetlands
classification and appropriate numeric standards. All created wetlands
will have ause-protected designation unless determined otherwise as a
result of asite-specific hearing.
(D) Compensatory wetlands shall be subject to the standards of the
segment in which they are located, unless the Commission adopts a
wetlands classification and appropriate numeric standards.
