1 Department of Environmental Conservation Division of Water August 13, Cruise ship discharge complaints ISSUE Public complaints and concern regarding cruise ship discharges in summer of Many of these reported discharges resemble exhaust gas cleaning system (scrubber) discharges. Scrubbers are used to remove sulfur from cruise ship air emissions and have recently been installed on large cruise ships. COMPLAINTS AND OBSERVATIONS ON CRUISE SHIP DISCHARGES Exhaust gas scrubber discharges Ocean Ranger observations: Open loop scrubber discharges have increased in 2018 as more scrubbers are being used and more washwater is pumped to meet EPA ph requirements. Ocean Rangers have observed foam, sheens, residues, and discoloration from the discharges. These observations have occurred throughout the cruise ship season. The discharges are large enough to be very visible from docks. The public could confuse these discharges for other wastewater discharges. Some ships are installing filter systems to reduce potential materials from discharge while they are in port. July Ketchikan Facebook discharge video: A video on Facebook in July showed a high volume discharge with bubbles and some foam, the discharge matched Ocean Ranger scrubber discharge observations. Ketchikan public questions: CPVEC (cruise ship) program responded to the City of Ketchikan regarding concern raised at a council meeting. This may have been due to the video on Facebook. The Ketchikan response memo is attached. The program also responded to a public complaint July 24, and responded to a question from Rep. Ortiz on July 25. Ketchikan Harbor office complaints: The Ketchikan harbor office notified CPVEC of a discharge with brown foam and oily appearance from the Golden Princess on July 19. Harbor staff talked to the ship and determined it was from an exhaust gas scrubber, the ship stopped use of the scrubber to stop discharging. Several operators have stopped discharges towards shore while in Ketchikan. Foam compliant Stephens Passage July 31: The CPVEC program received a compliant of a large amount of foam seen from a fishing boat the night of July 31 north of Petersburg. A video resembling the compliant latter appeared on Facebook. CPVEC staff checked vessel tracking, no large cruise ships were in the area at the time or within 12 hours prior to the compliant. BACKGROUND Cruise ship wastewater permitting: Under current state and federal statue authorities the CPVEC Program only issues permits for treated sewage and graywater (water from sinks, laundry, kitchens). The Department issues a general permit for large cruise ships, the current permit was issued in The current permit includes a mixing zone for metals and ammonia, but requires that bacteria and other indicators such as solids are met at the end of pipe. Large cruise ships are required to have Advanced Wastewater Treatment Systems onboard to remove almost all solids and disinfect wastewater prior to discharge.

3 PUBLIC WORKS / ENGINEERING DEPARTMENT CITY OF KETCHIKAN Mark Hilson, P.E., Public Works Director Administrative Offices Seth Brakke, P.E., Assistant Public Works Director PH: Kara Jurczak, P.E., Senior Project Engineer FAX: MEMORANDUM TO: CC: FROM: Karl Amylon, City Manager Lacey Simpson, Assistant City Manager Steve Corporon, Port and Harbors Director Daniel Berg, Acting Port & Harbors Director David Dixon, Port Operations Coordinator Mark Hilson, P.E., Public Works Director DATE: July 24, 2018 SUBJECT: Cruise Ship Discharges At the July 19 regular City Council meeting, during the persons to be heard portion of the meeting, public comment was made by Ms. Jessica Miles regarding cruise ship discharges. It appears that the suspect discharges Ms. Miles was referring to are from exhaust gas scrubbers and not from wastewater (nor from greywater). Exhaust gas scrubbing is a relatively new installation that uses water to clean exhaust gas. Discharges of this nature are permitted, but regulated by the United States Environmental Protection Agency (US EPA) through the administration of a Nationwide General Permit. While the Alaska Department of Environmental Conservation (ADEC) does not authorize the discharge, they do have other water quality standards relative to discharges that they may be able to enforce. Also, ADEC can take compliance actions based on the US EPA s General Permit standards. And finally, the United States Coast Guard Marine Safety Detachment (USCG MSD) investigates and has authority to take various enforcement actions with regard to discharges that involve petroleum distillates (oily sheen). It is my understanding that the discharges that have been recently observed are not compliant with water quality standards of existing permits or regulations, and as such ADEC and USCG MSD are investigating. In order to stop the discharges from occurring, staff has notified the cruise ship s agent to cease the discharge, which resulted in a cooperative response that has ceased the discharge. We have also notified John Kimmel with Cruise Line Agencies of Alaska to cease all such non-compliant discharges while vessels are in port.

4 It is my understanding that ADEC is gathering information on this new exhaust gas scrubber discharge and working with the US EPA and the vessel operators in order to make permanent modifications to ensure compliant discharges. In the meantime, Port and Harbors staff will remain vigilant in looking out for discharges such as these, and when observed, documenting and notifying appropriate authorities as well as cruise ship agents as necessary. Should the public observe continued discharges, ADEC is the regulatory agency with the most resources here in Alaska to deal with the issue: ADEC Ed White Environmental Program Manager I Commercial Passenger Vessel Environmental Compliance Program 410 Willoughby Ave, Suite 303 Juneau, AK edward.white@alaska.gov Albert Faure Environmental Engineer Associate Commercial Passenger Vessel Environmental Compliance Program 410 Willoughby Ave Suite 303 Juneau, AK albert.faure@alaska.gov To report discharges with an oily sheen contact: USCG MSD 1621 Tongass Ave Suite
