DNV IMO-Approves Bio Sewage Plant from G&O

Det Norske Veritas (DNV) has just IMO-approved the biological sewage treatment plant from Gertsen & Olufsen (G&O), a leading Scandinavian developer of a.o. sewage treatment systems targeted for ships and offshore use. The revised guidelines on treatment of black water, IMO MECP 159(55) Resolution, comes into effect on Jan. 1, 2010. As the resolution entails new and significantly stricter standards, it represents a massive challenge to shipbuilders and designers. The guidelines apply to sewage treatment plants on ships of 400 grt and above as well as on smaller ships certified to carry a crew of more than 15. One answer to the technological challenge has surfaced following DNV’s approval of the G&O Bioreactor in accordance with the new IMO resolution.

No Discharge Zone in Ohio waters of Lake Erie – proposal

The Environmental Protection Agency (EPA) issued a Notice stating that it has received an application from the State of Ohio to have Ohio waters of Lake Erie designated a No Discharge Zone for vessel sewage. Normally, this is largely a matter of concern for recreational vessels. In this instance though, state waters extend out to the boundary with Canada. Commercial vessels transiting these waters, extending the majority of the distance from Buffalo to Detroit, would have to secure their automatic sewage treatment systems to prevent inadvertent discharges. Comments on this proposal should be submitted within 30 days. 69 Fed. Reg. 53067 (HK Law).
