2) Eagle Ridge System 1 consists of 13 septic tanks, an aerated attached-growth denitrification tank, three equalization surge tanks two closing tanks, and a 10-zone subsurface drip irrigation system.

Eagle Ridge ll is designed to treat an average wet weather flow of 0.0026 million gallons per day (MGD) and a maximum flow of 0.0038 MGD. System ll consists of seven septic tanks and a trench drain field system.

Bio-solids produced at the three treatment centers are pumped and transported to the Grand Marais Wastewater Treatment Facility.

The preliminary determination to reissue this wastewater permit is tentative.
