# 2007 Small Ship Wastewater Sampling Results

In 2001, Alaska Statute (AS) 46.03.460-46.03.490 established the Commer cial Passenger Vessel Environmental Compliance Program (CPVEC), which is administered by the Alaska Department of Environmental Conservation (ADEC) and applies to large 1 

# and

small 2 

# commercial passenger vessels. The law requires small vessels to sample their wastewater discharges twice per season. Several key a spects of the CPVEC program, such as payment of environmental compliance fees and compl iance with wastewater discharge standards, became effective for small commer cial passenger vessels on January
1, 2004.

Small cruise ships are now required to meet standard term s and conditions, or seek alternative terms and conditions in order to discharge bl ackwater 3 

# and graywater 4 

# in

Alaska marine waters. Under standard terms and condition s blackwater, graywater and

other wastewater must contain no more than 200 fecal col iform per 100 milliliters and no more than 150 milligrams per liter of total suspended solids.

Alaska‘s original CPVEC law in 2001 established the standard t erms and conditions and the alternative terms and conditions. Changes to Alaska’ s CPVEC law in 2004

established additional alternative terms and conditions A S 46.03.462 (e) also known as a best management practices plan. As part of the 2004 law, t he interim protective measures allowed under AS 46.03.463(b) and (c) are now the same as the alternative terms and conditions permitted under AS 46.03.462. For more information a bout best management practices please see the cruise ship web site at the f ollowing address. http://www.dec.state.ak.us/water/cruise_ships/small_vessel_d ischargeoptions.htm

In 2007, all registered small vessels obtained approved Best Management Practices plans and operated under these plans. The AMHS ferries operate d under approved conditional status Best Management Practices plans, which were rene wed in 2007. The Best Management Practices regulations, 18 AC 69.046, became effect ive on May 18, 2006.

Eighteen small ships registered with the CPVEC progra m in 2007, including five state ferries that operate in Alaska year-round. One small shi p, the Hanseatic did not discharge into Alaskan waters and was not sampled. Table 1 (Parts 1 & 2) summarizes the 2007 small ship sampling results using the median 5 

# results for each pollutant. Data from the 17 ships were combined and results show that small-ship efflue nt does not meet water quality standards at the end of pipe for fecal coliform, ammonia, chlorine, arsenic, copper, nickel, and zinc.

# The median is the middle of a distribution: half the scores are above the median and half are below the median. The

median is less sensitive to extreme scores than an avera ge and is thus a better measure for skewed distributions

# Wastewater results for individual ships

Tables 2 through 5 show the 2007 twice-per-season sampling resu lts for each of the 17 ships that reported. Samples were analyzed for conventio nal and priority pollutants (see Table 6). Results highlighted in yellow are outside the s tandard terms and conditions or appropriate water quality standard. The small ships operat ing under best management practice plans do not need to meet standard terms and cond itions, so no enforcement action was required. DEC does look for progress on wastew ater sample results, and requires improvements prior to issuing extensions to the B est Management Practices plans.

Bacteria

Small ships continue to try to balance bacterial disi nfection and chlorine use. Chlorine is used to disinfect bacteria, but it is toxic to marine orga nisms and high residuals must be

avoided. The median total residual chlorine result for mi xed black and graywater is 10 times the Alaska’s marine water quality standard (AMWQS) . The maximum total

# Page 3 of 13

residual chlorine results for small-ship graywater and blackw ater were 3.5 mg/L and 2.5 mg/L, respectively. The maximum total residual chlorine for mixed graywater and blackwater was 33.2 mg/L—more than 4400 times (AMWQS). The fecal coliform standard is 200 colonies per 100 ml to meet AMWQS for secondar y-contact recreation. The most stringent AMWQS is 14 colonies per 100 ml to collec t shellfish for raw consumption, and is the standard used to protect all uses of all waters. Blackwater has the highest median fecal coliform results. At over 2,300, 000 colonies per 100 ml, the median is more than 160,000 times the AMWQS for raw consu mption of shellfish. The maximum fecal coliform result for mixed blackwater or gra ywater was from the Spirit of Oceanus. At 20,000,000 colonies per 100 ml, this is over 1 million times AMWQS for raw shellfish consumption.

Other Pollutants

One of the two samples for each ship was analyzed for 167 “priority pollutants:” 13 total metals, 12 dissolved metals; 72 volatile organic compounds (V OCs); 70 bases, neutral, acids (BNAs). Some small ships have separate graywater and blackwater discharges. The department allowed these ships to sample priority pollut ants 6 

# on only one of their wastewater discharges per season.

Most of the priority pollutants were not detected in smal l ship discharges. Table 5 includes only priority pollutants with medians that exceeded the practical quantitation limit (PQL) or a pollutant with a maximum value 10 times the PQL. Alaska uses dissolved metal concentration (a subset of total recove rable metals) for its water quality standards, but Table 5 also includes the total recoverable m etals results for informational purposes. The pollutants not listed here are considered not detected and the analysis of those pollutants is unnecessary.

Currently there are no AMWQS for 3&4-methylphenol, 2-cholo rphenol, bromoform, chloroform, benzoic acid and phenol. However, there are Alaska Marine Water Quality Standards (AMWQS) for arsenic, chromium, copper, lead, se lenium, nickel and zinc.

All small ships met the AMWQS for dissolved chromium. M ost small ships that operated in Alaska in 2007 exceeded the AMWQS for nickel and arsenic. All small ships that were sampled exceeded the AMWQS for copper. Two ships exceeded the AMWQS for lead,
one for selenium, and seven for zinc.
