(a) For the purpose of preparing the hydrogeologic site investigation report under 329 IAC 10-15-4 and to determine the applicable design requirements of 329 IAC 10-16-9 and 329 IAC 10-17-2, "aquifer of significance" means an aquifer:
(b) An aquifer that is described in subsection (a)(1) is an aquifer of significance if it meets the following criteria:
K > 37/b2 Where: K = Hydraulic Conductivity (cm/sec). b = Saturated Thickness (ft). The location of the determination is based on obtaining a maximum discharge from the aquifer.
The determination must consider the entire vertical extent of the aquifer to obtain a full "average" K value of all distinctive layers of a nonhomogeneous aquifer if distinctive layers are hydraulically connected.
(c) An aquifer that is described in subsection (a)(1) is an aquifer of significance if the following criteria are met:
