- Changing the permit to an NPDES permit for a new discharge through a new outfall to Longview's Consolidated Diking Improvement District No. 1 Ditch #5.
- To begin discharging wastewater to the Three Rivers Regional Wastewater treatment plant instead of Nippon. The regional wastewater treatment plant discharges to the Columbia River.
