The Environmental Protection Commission proposed to amend Iowa Admin. Code chs. 38, Private Water Well Construction Permits; 39, Requirements for Properly Plugging Abandoned Wells; 49, Nonpublic Water Supply Wells; and 82, Well Contractor Certification, and to adopt new Chapter 48, Ground Heat Exchanger (GHEX) Loop Borehole Systems. Changes would rescind current GHEX language and standardize the minimum construction requirements for this type of well. There will be six hearings throughout early April, and the deadline for public comment is April 12, 2011. http://www.legis.state.ia.us/aspx/ACODOCS/DOCS/03-09-2011.Bulletin.pdf pp. 1242-60.
