Non Compliance is due to water quality impairments to the East Gallatin River caused by impaired feeder streams to the East Gallatin River. • Declining base flows in our local streams and rivers will lead to less buffering capacity against pollutant loading. • Storm water should be treated prior to entering Bozeman Creek 19 Bozeman Creek Community Park including Bozeman Creek water quality improvement project Artistic Rendition � w I• 20 Project objectives Remove contaminants from storm water runoff Comply with Phase II NPDES MS4 permit Help enable Bozeman Waste water treatment plant- to keep in compliance with DEQ issued discharge permit.

The Bozeman Creek Enhancement Plan was adopted by the Bozeman City Commission as policy in July,2012. The plan has four goals: Foster broad awareness of and appreciation for Bozeman Creek.leading to a strong community stewardship ethic. Restore ur the natal processes necessary for a functioning creek ecosystem Improve water quality to support aquatic life and primary contact recreation Provide ample public access and appropriate recreational opportunities along the creek corridor,while ensuring resource protection. Me plan also identities actions that can help to accomplish these goals. Your proposed project was identified as one of these actions,and is directly in line with the stated goals for Bozeman Creek. Specifically.the project would improve water quality in the creek,increase wetland and open water habitat adjacent the creek.provide a trail connection along the creek corridor.mod offer educationaliinwrpretive benefits to the community. The committee appreciates your sustained effort to bring this worthy project to fruition.

Manion no longer lets his kids eat the fish they catch in the creek because it's too polluted. By AMANDA RICKER, Chronicle Staff Writer,The Bozeman Daily Chronicle Bart Manion has watched disposable diapers,motor oil containers and red,plastic keg cups come out of the stormpipe on his south Bozeman property and flow into Bozeman Creek. In the older parts of town, any trash,pollutants and dirty water washed down curbside storm drains is piped to the nearest creek and released. "When we first moved here,my sons were on this creek everyday fishing," Manion said. "We were eating the fish left and right.Then finally, I had friends say, `Oh don't do that. You'll be paying for that later."' Just from Story to Tamarack streets,there are 41 "outfalls," or drain pipes like Manion's, that flush stormwater from the roads directly into Bozeman Creek, Street Superintendent John Van Delinder said. Whether it's runoff from Main Street,the Montana State University campus, or the northeast neighborhood, if the pavement it washes across was built before the mid- 1980s,it likely drains into a local waterway, city engineer Dustin Johnson said. In roughly two-thirds of Bozeman neighborhoods, stormwater is not treated, Johnson estimated. "The core of the city is all untreated," he said. But the Bozeman City Commission has made it a top priority to change that. The commission in April unanimously backed the idea of creating a storm water utility, which would involve installing infrastructure to deal with stormwater and charging residents a new monthly fee on their sewer bills to pay for it. 36 Applicants commitment to stormwater treatment education Alt , �nvutw+r.uu Bart Manionof the InnWractiveWaterUse&RocumeConservationCeMerrj showftstommaterflltrationsystemseparates"meruheavy metals,volatile organics and bacteria through a passive filtration method that uses gravity rather than electric pumps.
