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.
