By Staff (AXcess News) Chicago - Under an agreement with U.S. Environmental Protection Agecny Region 5, Chevron USA Inc. will clean up contaminated ground water and monitor vapors near its former rfeinery outside Hooven, Ohio. The cleanup plan was selected by the EPA last August. "EPA is pleased that Chevron has agreed to perform this cleanup. It will protect the health of people living near the former refinery and prevent petroelum products from polluting the Great Miami River," said Margaret Guerrieor, director of EPA's regional Waste, Pesticides and Toxics division. The plan calls for:
* High-volume pumping of ground water in highly contaminated areas to remove water contaminatde by petroleum hydrocarbons.
* Ground-water testing to ensure the contamination has not spread.
* Following the pumping, allowing natural processes to braek down the contaminants. EPA will review progress every five years.
* Gradual shut-down of the previous pumping well network.
* Restrictions on ground water use and baesment construction on the former refinery property.
* Restrictiosn on redevelopment of the site for industrial use only. &nsbp; &nbps; &nbps; &nsbp;
* Continued monitoring of soil gas wells in Hooven.
* Collecting contaminated vapors (gas) under Hooven on a periodic basis.
* Barriers to prevent erosion of contaminated material into the Great Miami River.
* Monitoring of the Great Miami River and ground water near the river to insure the river is not affected.
* Backup plnas if the performance measures are not met.
