A bus ready to be washed in the bus washing station at Parking and Transportation. A valved drainage systems allows the facility operator to direct the wash water discharge to an oil-water separator that then drains to the sanitary sewer. During other times, runoff is directed to the storm sewer.
In 1995, EPA published the final notice for Phase I of the Multi-Sector General Storm Water Permit Program. The program included the requirement of the permitting of stormwater discharges and the development of a Stormwater Pollution Prevention Plan (SWPPP) by each industrial facility discharging storm water, including transportation terminals where vehicle maintenance and fueling activities were conducted. In order to comply with this program, a SWPPP was created for the University’s Parking and Transportation Facility on Millmont Street. The SWPPP provides P&T with a way of monitoring their activities in order to ensure that any accidental spills at the facility do not enter the storm sewer. The storm sewer on site drains to Meadow Creek while other drains onsite discharge to the sanitary sewer which heads to a plant for treatment. The plan aims to ensure that if a discharge were to occur, any spilled material would be directed to the sanitary sewer where it would not pollute surface waterways. All drains inside the vehicle maintenance buildings and bus washing areas drain to the sanitary sewer via an oil water separator. The oil water separator treats the water on site before sending the water to the water treatment plant for further treatment. An oil water separator is also installed in the drain in the bus parking area. This oil water separator removes any oil that may have dripped from the busses when not in service. The separator then discharges the clean water to the storm sewer. In addition to the oil water separators, secondary containment devices such as berms around fueling areas and storage containers are in place to contain any spill. Recently, canopies were installed over the vehicle fueling areas to prevent rain from washing away any fuel drips or spills. These containment devices, known as Best Management Practices (BMPs), are in place to provide multiple levels of protection from stormwater pollution.
