Item B: Three Basin Rule 2025 (Action) DEQ will propose to amend the Three Basin Rule following the EQC's direction in November 2024. The proposed changes aim to allow limited issuance of National Pollutant Discharge Elimination System permits while preserving the original intent of the rule. The changes will also streamline the Onsite-Wastewater Treatment and Control Facility permitting process, enabling facilities to obtain permits for system repairs without needing EQC approval, provided there is no increase in flow or waste strength.
