DES MOINES - The Iowa Department of Natural Resources (DNR) is hosting an informal stakeholder meeting on March 12, regarding the proposed five-year renewals of NPDES General Permits #8 and #9 (GPs #8 and 9). The purpose of this meeting is to accept comments and answer questions on possible changes to the GPs. The DNR is specifically seeking comments on the clarity, feasibility, and potential impact of the proposed changes. Formal rulemaking to renew GPs #8 and #9 is expected to begin in mid-2026.
GP #8 covers discharges from hydrostatic testing, tank ballasting, and water lines, and GP #9 covers discharges from dewatering activities and residential geothermal systems.
The meeting will be held on Thursday, March 12 at 11:00 am. The meeting is open to the public and will be held virtually via Google Meet.
