Small Vessel Discharge Options
The Best Mangment Parctices exemption law exipired in 2016. Discharge under existing NS DRft BMPs will be covered by a No Action Assurance Memo. Please contact CPVEC for additional information.
Wastewater Discharge Options under the Commercial Passenger Vessel Environmental Compliance Program
Alaska law requires that the owner or operator of a small commercial passenger vessel (50 to 249 overnight passengers determined by the number of lower berths), registered under the Commercial Passenger Vessel Environmental Compliance (CPVEC) Program, may not discharge treated sewage, graywater and other wastewater in Alaska waters unless the vessel meets one of the options described below. The vessel owner or operator must choose one of the following wastewater discharge options at the time of registration with the CPVEC:
- Obtain Department approval to operate under alternative terms and conditions described in AS 46.03.462 (c). You, as the owner or operator, must get Department approval by submitting a completed application and your Best Management Practices Plan (BMP) to the Department on or before March 1 of the year that you intend to begin operating in Alaska. The Department will approve a BMP if it meets the requirements of 18 AAC 69.046. The Department may approve a BMP for up to five years. Since 2004, most small cruise ships and ferries have used this method.
- Obtain a discharge permit from the cruise ship program. You may apply for an individual permit to discharge wastewater in Alaska marine waters. The permit terms and conditions would include requirements for operations, monitoring, inspections, sampling, reporting, and Department access to your records beyond the requirements for each in a BMP. Note that no small cruise ship owners or operators have yet applied for a discharge permit.
- No discharge of wastewater in state waters. This option requires you to hold graywater and blackwater onboard for discharge outside of Alaska marine waters, or for shoreside disposal. This option has been selected by some small cruise ships. This option does not require Department approval, effluent sampling, or submitting wastewater sampling plans.
For additional information and questions, please contact the cruise ship program.
Note: Small vessels do not fall under the Large Cruise Ship General Permit
