From The Pueblo Chieftain (Chris Woodka):
The city of Pueblo laid out its case for more time to study which methods of reducing contaminants, especially selenium, in wastewater to state and county officials Friday.
“The city’s approach is not just a study, but an adaptive management program,” said Gabe Racz, the city’s attorney for water quality issues.
Pueblo plans to ask the Colorado Water Quality Control Commission in December for an extension of temporary modification for discharges from the sewage treatment plant east of Pueblo. The city wants three years to meet sulfate standards and 10 years for selenium levels.
There are complicated, interrelated processes that need to be implemented in order to meet new federal standards for selenium, ammonia and nutrients, said Gene Michael, wastewater director for Pueblo.
