The <br />Department shall report its findings and recommendations to the Environmental Review <br />Commission on or before November 1, 2014. <br />"SECTION 54.(e) This section is effective when it becomes law.

Stormwater runoff rules and programs. <br />(b2) For purposes of implementing ,State stormwater programs and <br />local stormwater programs approved pursuant to subsection (d) of this section, all of the <br />following shall apply: <br />"btlilt ttpefl "Built -upon area" means impervious surface and partially <br />impervious surface to the extent that the partially impervious surface does <br />not allow water to infiltrate through the surface and into the subsoil. <br />"Built -upon area" does not include a slatted deck or the water area of a <br />swimming pool. <br />Vegetative buffers adjacent to intermittent streams shall be measured from <br />the center of the stream bed. <br />The volume, velocity, and discharge rates of water associated with the <br />one -year, 24 -hour storm and the difference in stormwater runoff from the <br />predevelopment and postdevelopment conditions for the one -year, 24 -hour <br />storm shall be calculated using any acceptable engineering hydrologic and <br />hydraulic methods. <br />Development may occur within a vegetative buffer if the stormwater runoff <br />from the development is discharged outside of the vegetative buffer and is <br />managed so that it otherwise complies with all applicable State and federal <br />stormwater management requirements. <br />The requirements that apply to development activities within one -half mile <br />of and draining to Class SA waters or within one -half mile of Class SA <br />waters and draining to unnamed freshwater tributaries shall not apply to <br />development activities and associated stormwater discharges that do not <br />occur within one -half mile of and draining to Class SA waters or are not <br />within one -half mile of Class SA waters and draining to unnamed freshwater <br />trihntariec " <br />(d) The Commission shall review each stormwater management program submitted by <br />a State agency or unit of local government and shall notify the State agency or unit of local <br />government that submitted the program that the program has been approved, approved with <br />modifications, or disapproved. The Commission shall approve a program only if it finds that <br />the standards of the program equal those of the model program adopted by the <br />Commission pursuant to this section. <br />Page 4 H760 [Edition 1 ] <br />
