Overview
CHENA MARINA RSA is a stormwater outfall in Fairbanks, Alaska, United States. It manages stormwater runoff from the Chena Marina area, discharging into local waterways.
CHENA MARINA RSA is a stormwater outfall located in Fairbanks, Alaska, within the Fairbanks North Star Borough. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the Chena Marina area, which includes residential and recreational zones. The facility is operational and plays a role in managing urban stormwater in a region characterized by cold climates and permafrost conditions. Stormwater outfalls like CHENA MARINA RSA are regulated under the US EPA National Pollutant Discharge Elimination System (NPDES) program, specifically through Municipal Separate Storm Sewer System (MS4) permits. In Alaska, the EPA Region 10 oversees compliance, and facilities must implement best management practices to control pollutants in runoff. The outfall likely discharges to the Chena River or its tributaries, which are part of the Tanana River watershed. The environmental significance of this outfall lies in its contribution to protecting water quality in the Chena River, a key water body for recreation and aquatic habitat. Effective stormwater management is critical in Fairbanks due to seasonal snowmelt and permafrost dynamics, which can influence runoff patterns and pollutant transport. The facility supports local flood control and water quality objectives.
Environmental context
The Chena Marina RSA outfall discharges stormwater into the Chena River, a tributary of the Tanana River in interior Alaska. The region experiences a subarctic climate with long winters and short summers, leading to snowmelt-driven runoff peaks. Permafrost in the area affects infiltration and runoff patterns, making stormwater management challenging. The Chena River supports salmon runs and other aquatic life, so controlling pollutants from urban runoff is essential for maintaining ecosystem health.
Frequently asked questions
CHENA MARINA RSA is located on Sea Way Road in Fairbanks, Alaska, within the Fairbanks North Star Borough, United States.
CHENA MARINA RSA is a stormwater outfall that discharges stormwater runoff from the Chena Marina area into local waterways, helping to manage urban stormwater and reduce flooding risks.
Stormwater outfalls in the United States are regulated under the Clean Water Act through the NPDES MS4 permit program. CHENA MARINA RSA likely operates under a Phase II MS4 permit, requiring best management practices to control pollutants.
The outfall likely discharges to the Chena River or its tributaries, which flow into the Tanana River. The Chena River is an important water body for recreation and salmon habitat.
Fairbanks has a subarctic climate with permafrost, which reduces infiltration and increases runoff during snowmelt. Proper stormwater management prevents flooding and protects water quality in sensitive aquatic ecosystems like the Chena River.
