Current law specifies the circumstance under which a point source of a
discharge having a thermal component, when modified, is not subject to more
stringent effluent limitations. This bill specifies that this exemption applies to
modified point sources with respect to water quality based effluent limitations only.
For further information see the state and local fiscal estimate, which will be
printed as an appendix to this bill.
