Description of Services:Cummings Environmental operations are closely tied to Cummings Marine, Inc. (a barge storage and treatment operation on McKellar Lake), located approximately 2 miles from one another. Cummings Environmental was the primary focus of the audit, however the barge operation permits, agency interviews and inspection records for Cummings Marine, Inc. were also obtained.

Cummings Environmental at Harbor Avenue consists of a wastewater treatment plant, and a small tank farm for the storage of oily water, recovered oil, and other wastewaters. Two frac tanks may also be used to store oily water when needed.

Cummings Marine activities at Port Street consist of several barges and tugboats docked on McKellar Lake and a dispatch office and parking lot which are located on a total of approximately 2 acres adjacent to the lake.

Oily water and fuel-contaminated waters are received at Cummings Environmental in bulk, and placed into one of two storage tanks. The waters are allowed to gravity settle, and are stored in a single tank prior to treatment in the wastewater treatment plant. The wastewater treatment plant consists of a receiving tank, flocculation unit, filter press, sock filtration, carbon adsorption, and UV light treatment.

At Port Street, one of the barges is dedicated to the storage of bilge water (oil/water mixture), and petroleum water (gasoline/water mixture). These materials are collected from tow boats, and other vessels offshore and are stored in separate compartments within the barge. Used oil and gasoline are recovered from the waters through gravity separation. The resulting wastewaters generated from these operations are transferred to a wastewater treatment unit located on another barge (total capacity 500,000 gallons). The treated wastewaters are discharged directly to receiving waters under an NPDES permit. Cummings Environmental tests recovered oil generated from both facilities for chlorinated hydrocarbons prior to truck shipment offsite for use as a boiler fuel.
