Boise’s two municipal sewage treatment plants are being required to meet limits on how much copper, lead and cadmium they can release into the Boise River, according to new U.S. Environmental Protection Agency wastewater discharge permits announced today by Chuck Clarke, EPA’s Northwest regional administrator in Seattle.

The permits call for the city of Boise to begin to meet the new limits for cadmium and lead no later than November 2, the date the permits take effect. The permits allow five years for the treatment plants to come into compliance with the new limits on copper.

"Compliance with the lead and cadmium limits should be little or no problem,” said Clarke. “In fact, if the new permit requirements had been in effect for the last two years, there would have been no violations at either the Lander Street plant or at the West Boise plant."

EPA gave the city of Boise five years to meet the copper limits because the city would need that much time to figure out how to solve the copper problem, said Clarke. Several options are available to the city to deal with the new copper limits but all of them will take time to evaluate and develop.

The Lander Street plant (at 790 Lander Street) and the West Boise plant (at 11818 Joplin Road) both treat wastewater from residential, commercial and industrial sources. On average, the West Boise plant discharges 11.3 million gallons of treated wastewater a day to the Boise River. The average daily discharge from Lander Street is 8.4 million gallons.
