I was just wondering where that was. The marinas around here seem to have varying explanations ... as long as it doesn't get into the water, I'm fine.

If you had your own wastewater permit, you could treat bilge water mixed with oil and surfactants and discharge to the sanitary sewer or surface water, in accordance with the treatment reqirements of the permit. You do not and VERY few marinas have this type of permit.

The only other alternative is treatment at a CWT (Centralized Waste Treatment) facility, permited to take subcatagory B (oily water) wastes under the clean water act. Bilge water is identified in the CWT regulations as a subcatagory B waste.

These are the businesses that can treat it properly. The best known in the Annapolis are are FCC Environmental and Clean Harbors. There are many haulers that will take it to these.
