Sec. 2.
For the purpose of this rule ( 327 IAC 5-7 ):
"Alternative effluent limitations" means all effluent
limitations or standards of performance for the control of the thermal
component of any discharge which are established under section 316(a) of the
CWA and this rule ( 327 IAC 5-7 ).
"Balanced, indigenous community" is synonymous with the term
"balanced, indigenous population" in the CWA and means a biotic community
typically characterized by diversity, the capacity to sustain itself through
cyclic seasonal changes, presence of necessary food chain species and by a lack
of domination by pollution tolerant species. Such a community may include
historically nonnative species introduced in connection with a program of
wildlife management and species whose presence or abundance results from
substantial, irreversible environmental modifications. Normally, however, such
a community will not include species whose presence or abundance is
attributable to the introduction of pollutants that will be eliminated by
compliance by all sources with section 301(b)(2) of the CWA, and may not
include species whose presence or abundance is or would be attributable to the
imposition of alternative effluent limitations pursuant to section 316(a) of
the CWA in place of otherwise applicable effluent limitations under section 301
or section 306 of the CWA.
"Representative important species" means species which are
representative, in terms of their biological needs, of a balanced, indigenous
community of shellfish, fish and wildlife in the body of water into which a
discharge of heat is made.
