From the Summit County Citizens Voice (Bob Berwyn):
“Phosphorus and nitrogen are incredibly prevalent. They’re in animal waste, human waste, fertilizer, and we’ve ignored it for 20 years,” said Becky Long, water caucus coordinator for the Colorado Environmental Coalition. If left unaddressed the pollution causes algae blooms and dead zones in waterways, impacting aquatic wildlife and Colorado’s outdoor recreation opportunities. Long said she’s encouraged by the Colorado Water Quality Control Commission’s early support for the new standards limiting nitrogen and phosphorus pollution. The rule is still subject to challenge at subsequent hearings, as well EPA review and final approval. Long said the standards go beyond simply protecting aquatic life and human health by addressing potential impacts to recreation…
Phosphorus has been identified as a potential problem in Cherry Creek reservoir. In the high country, effluents from Grand County have affected water quality in Grand Lake. The two pollutants are a problem anywhere there’s a lot of effluent going back to the stream, for example downstream of the metro wastewater treatment facilities east of Denver, Long said, explaining that the new rules are forward looking and will protect water quality for the next 50 years, as the state’s population grows by up to 5 million.
While she expects some challenges from agricultural stakeholders and perhaps some municipalities, Long said the rules are written with built-in flexibility and can be implemented in phases, as waste water treatment plants plan for future upgrades. State water quality regulators were responsive to small- and mid-sized communities as they crafted the rule, she said.
Finally, it’s important to remember that the pollution generated in Colorado have impacts far beyond the borders of the state. Addressing the issue of nutrients here helps tackle the serious issue of the dead zone in the Gulf of Mexico, Long said. “We need to own the fact that this is us causing the problem. It’s not Mr. Burns, it’s us, every time we flush the toilet. If we don’t pass the state rule, we could meet the same fate as Florida. The EPA will write a rule that’s a lot more stringent and we’ll lose our chance to do this at the state level,” she said.
