JEFFERSON CITY, MO, JUNE 23, 2010 – The Missouri Department of Natural Resources is investigating a wastewater overflow that resulted in the release of an estimated 54,000 gallons of sewage into an Independence creek Tuesday.

Independence officials notified the department Tuesday that an operational error allowed the sewage to escape from the Sugar Creek pump station, northwest of the BP Amoco site in Sugar Creek, and enter Rock Creek for approximately an hour between 8 a.m. and 9 a.m.

The department dispatched an investigator from its regional office in Lee’s Summit to determine the extent of the environmental damage caused by the release.

Clean water regulations require the city to submit a report detailing the release to the department within five days. The department will base future enforcement action on the city’s report and the results of its on-scene investigation.

The department considers discharges of wastewater from sanitary sewer collection systems to be potential threats to public health and the environment. Such discharges have the potential to contaminate lakes and streams, causing serious water quality problems.

Sanitary sewer overflows can be caused by mechanical failure; obstructions in sewer lines; infiltration of rainwater and snow melt into aging systems; or undersized systems that cannot compensate for sudden increases in wastewater.

Communities across Missouri produce millions of gallons of wastewater that must be properly transported and treated before being released to waterways. However, some communities are facing challenges in accomplishing this.

In order to protect public health and the environment, the department requires communities to take appropriate action to eliminate their sanitary sewer overflow issues. To do this, communities should develop a system to track information about such incidents, including the date, time, location and size of the overflow, weather data, who notified them, when they notified the department and the measures taken to respond. The community can then use this data to aid in developing a plan to inspect the collection system, and plan and finance system upgrades.
