The Department of Environmental Quality gives notice of public hearings and a comment period on the draft rules of a negotiated rulemaking to provide for a revised method to estimate wastewater flow from single family dwellings that is more consistent with domestic water usage statewide. The proposed revisions would provide for a more refined soil classification system that will allow more precise sizing of drainfields. The rule would also provide a definition of "module" to assist understanding and applicability of the rule within the regulated community. Hearings will be held May 22 and June 5, 2008. Comments are due May 23, 2008. http://www.deq.idaho.gov/rules/subsurface/58_0103_0801_negotiated.cfm.
