The answer to your bilge- water discharge problem:
Keene Marine Discharge
Ready now-to meet the July 1 deadline.
Keene has long been part of the marine industry—supplying Keene (Bowser) fuel and lube filters and other equipment for over 75 years. So to help you meet the July 1 dead- line, we've developed a complete system that automatically assures that bilge dis- charge is within limits acceptable under the Federal Water Pollution Control Act and related Coast Guard regulations:
Automatic fail-safe control.
Proof of compliance.
Coast Guard regulations.
Pennant to identify installation.
The Keene Marine Discharge Control System removes oil and other contaminants from bilge water and monitors the effluent stream. The fail-safe control permits only sheen-free water to be discharged.
The system includes a real-time continuous recorder which prints a chart verifying the purity of all overboard discharge. This data becomes part of the captain's or master's log, providing per- manent proof of compliance.
Bilge water discharged through the Keene system exceeds EPA and Coast Guard "no sheen" requirements. In addition, the U.S. Coast Guard has agreed to waive the bilge containment provisions of Title 33, Subchapter 0, paragraphs 155.330 through 155.360 to vessels with the Keene system installed.
Large reflective pennants are furnished for attachment to the exterior of vessels which have the Keene system installed. These pennants readily identify Keene- equipped vessels, and may eliminate these vessels as suspected polluters. 16 Maritime Reporter/Engineering News
