In 2011, Boise Weekly first told you about new guidelines that included never-before-seen restrictions on phosphorous that makes its way to the Boise River. The Environmental Protection Agency had sent down new rules to the city, in order to radically reduce the amount of phosphorous that makes its way into the Boise River. The EPA said that Boise needed to bring its phosphorous discharges down from approximately 1,100 pounds per day to approximately 15 pounds daily.
"Our permits have never had a limit on phosphorous before," Paul Woods, Boise's Environmental Division manager, told BW in 2011. "This is brand new, and it's a very big issue."
The city began crafting a two-part plan, first using something called its Enhanced Biological Nutrient Removal. Secondly, the plan includes the Dixie Drain, a 49-acre parcel of land between Notus and Parma. You can read about it here.
Tuesday, Aug. 20, officials with the city's Public Works Department will brief the Boise City Council on its phosphorous-removing process and its cost, estimated to be $47 million over 20 years.
As a result, Boise residents will see an increase in their sewer rates beginning Tuesday, Oct. 1. For an average single family dwelling, the monthly charge will increase by $1.18 to $25.11 per month.
The Council will be briefed at its 3 p.m. work session Tuesday, Aug. 20.
