This plant discharges waste water that is allowed to flow into the Atlantic Ocean The Environmental Protection Agency (EPA) has ordered that the waste water may not be excessively warm so that thermal pollution of the marine envuonment near the sont can be avoided. Because of this order, the waste water is allowed to cool in specially constructed ponds and is then released into the ocean.
