The ini- tiative also required operators to gather and report more information and obtain a new type of wastewater discharge permit. Moreover, it authorized citizen lawsuits for alleged violations. In 2008, the Alaska Department of Environmental Con- servation issued a new large commercial passenger vessel wastewater discharge permit with a term of 2008 to 2010. The permit required additional reporting and sampling and contained interim (2008 and 2009) limits for ammonia, cop- per, nickel, and zinc, to allow permittees time to improve effluent quality. The interim limits required cruise ship operators to submit a source reduc- tion evaluation to DEC that documented prog- ress to achieve the final limits. The permit established fnal effuent limits for ammonia, copper, nickel, and zinc that applied Alaska water quality criteria at the point of discharge beginning in 2010. In April 2010, the DEC issued the 2010 large commercial passenger vessel wastewater dis- charge permit, which incorporated the previous statutory changes, added limits for stationary discharge, established limits based on treat- ment system used, and established a chlorine effuent limit for all ships. While it eliminated the source reduction evaluation requirements, the 2010 permit included updates to reporting, monitoring, permit transfers, and discharge restrictions. The Efort Continues On February 28, 2013, a new law allowed an extension of the 2010 permit and allowed the DEC to issue a new permit that includes mixing zones. Today, the DEC is developing a general permit compliant with the new statutes. About the author: Mr. Rob Edwardson retired from the Coast Guard in 2007, as a CWO3 with 20 years of service.
