Info

Shipyards’ stormwater runoff is typically regulated under a multi-sector general industrial stormwater permit. However, some states require facilities to have individual National Pollutant Discharge Elimination System permits for stormwater and to meet discharge limits. Permit requirements vary from state to state and can range from requiring a stormwater management plan, to using BMPs, to requiring zero discharges. Waste Generation and Management Wastes in the sector can be generated from process-related functions or from other activities such as operation of pollution control devices or remediation of past contamination. Spent abrasives and oil or oily water are typically the largest volumes of waste generated in shipyards. Hazardous Waste Management In 2005, 96 facilities in the sector reported to EPA’s National Biennial RCRA Hazardous Waste Report (BR) generating about 7,000 tons of hazardous waste. Waste paint and spent solvents, although produced less than spent abrasive and oily waste, generally constitute the sector’s largest hazardous waste stream. In 2005, painting and coating processes accounted for 42% of the total hazardous waste generated (about 3,000 tons). 16 Improvements in process management of coating application and equipment cleaning have resulted in reductions in the amount of painting and coating waste. For instance, in-line plural component mixers prepare coatings as they are required. This prevents the generation of paint waste from mixing more paint than is required to complete a job. Additionally, paint waste is now used in fuel blending, whereas previously it would have been solidified for land disposal. Shipyards are also reclaiming and reusing solvents used to clean spray paint equipment. The sector managed its hazardous waste in 2005 through disposal, treatment, and reclamation and recovery, in roughly equal proportions. The sector reported managing 6,000 tons of hazardous waste. The primary method of reclamation and recovery used by the sector was fuel blending. Waste Management Reported to TRI In 2005, the sector managed 7.2 million absolute lbs. of TRI-reported chemicals. When normalized by VOS, this was 55% less than in 1996. Figure 2 shows the trends in waste management by the sector. In 2005, 29% of the TRI-reported waste was disposed to land or released, 9% Figure 2 TRI Waste Management 1996–2005 Disposal or Other Releases Treatment 81% Energy Recovery 58% Recycling 44% 52% 8,000,000 1996 total: 13.1 million lbs 2005 total: 5.9 million lbs 55% 7,000,000 6,000,000 Normalized lbs 5,000,000 4,000,000 3,000,000 2,000,000 1,000,000 0 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 Notes: 1.

was treated, 8% was used for energy recovery, and 55% was recycled. Of the waste disposed or released, 11% was disposed. As shown in Table 3, copper and zinc accounted more than half of the total disposals in 2005; copper and nickel were the most frequently reported chemicals for this sector during the same year. 17 The quantity of waste that shipyards disposed, as reported to TRI, decreased from about 251,000 lbs. in 1996 to about 226,000 lbs. in 2005. The chemicals were disposed to land or transferred to offsite locations for disposal.
