2012 Ocean Ranger Guidebook 3-7-12 Job Aid Item: 7.2.j Text: Checked comparison of ship’s operational maintenance routine with actual preventative maintenance conducted. Checked records pertaining OWS system repairs. (33 CFR 151.10) What to check for: OWS if used must be operable. Check that system has been mainained and repaired if necessary. Job Aid Item: 7.2.k Text: Checked meter calibration records. (33 CFR 151.10) What to check for: Check records for evidence of meter calibration. Subsection 3: Bilges (33CFR155.770) General background: Oil or hazardous materials in a bilge are a potential source of pollution if not properly treated. Even if properly treated, too much waste could reduce the effectiveness of treatment. Some materials could be put into the bilge that equipment is not designed to handle- such as from the wastewater system. Large amounts of oil or hazardous waste has been identified by Ocean Rangers as a possible safety hazard when fumes or vapors accumulate. General Citation:33 CFR 155.770 Draining into bilges. No person may intentionally drain oil or hazardous material from any source into the bilge of a vessel. Job Aid Item: 7.3.a Text: Check bilge water management / ship specific bilge water management manual (33CFR155.770) What to check for: Check for procedures, systems in place to minimize the introduction of oil and hazardous materials into the bilges. Job Aid Item: 7.3.b Text: Check machinery bilge spaces for contamination with oil or hazardous wastes (33CFR155.770) What to check for: Check for sheens, sludge, odd odors, or unusual stains. Job Aid Item: 7.3.c Text: Check for contamination oil residues in bilges on bulkheads, piping, structures, within rose boxes. (33CFR155.770) What to check for: Check for sheens, sludge, odd odors, or unusual stains. Job Aid Item: 7.3.d Text: Checked for leakage from systems and engines into machinery spaces (e.g boiler Water blow down / wash waters?) (33 CFR155.770) 212
2012 Ocean Ranger Guidebook 3-7-12 What to check for: Check for sheens, sludge, odd odors, or unusual stains. Job Aid Item: 7.3.e Text: Check on oil usage, quantities, where lost, consumed or in bilges (33 CFR155.770) What to check for: Check oil record book and other sources for information for amounts of oil lost into bilge and recovered sludge/oily water. Job Aid Item: 7.3.f Text: Check for evidence of detergent usage in oily water separator / related equipment or used to remove appearance of sheen (40 CFR 110.4 / VGP 2.2.2) Background: Dispersants used in the bilge or oily water separator could interfere with the effectiveness of equipment removing oil. This could allow oily water to be discharged. What to check for: Check for evidence of detergent use in or near bilges and OWS equipment. Like chemicals / dosing equipment and other suspect liquids and chemicals / additives. Citations: 40 CFR 110.4 Dispersants. Addition of dispersants or emulsifiers to oil to be discharged that would circumvent the provisions of this part is prohibited. EPA VGP 2.2.2 Bilgewater All bilgewater discharges must be in compliance with the regulations in 40 CFR Parts 110 (Discharge of Oil), 116 (Designation of Hazardous Substances), and 117 (Determination of Reportable Quantities for Hazardous Substances) and 33 CFR §151.10 (Control of Oil Discharges). In addition: Vessel operators may not use dispersants, detergents, emulsifiers, chemicals or other substances to remove the appearance of a visible sheen in their bilgewater discharges. Except in the case of flocculants or other required additives (excluding any dispersants or surfactants) used to enhance oil/water separation during processing (after bilgewater has been removed from the bilge), vessel operators may not add substances that drain to the bilgewater that are not produced in the normal operation of a vessel. The use of oil solidifiers, flocculants, or other required additives are allowed only as part of an oil water separation system provided they do not alter the chemical make-up of the oils being discharged and they are not discharged into waters subject to this permit. Routine cleaning and maintenance activities associated with vessel equipment and structures are considered to be normal operation of a vessel if those practices fall within normal marine practice. All vessels must minimize the discharge of bilgewater into waters subject to this permit. This can be done by minimizing the production of bilgewater, disposing of bilgewater on shore where adequate facilities exist, or discharging into waters not subject to this permit (i.e., more than 3 nautical miles (nm) from shore) for vessels that regularly travel into such waters. Though not regulated under this permit, EPA notes that discharges of bilgewater outside waters subject to this permit (i.e. more than 3 nm from shore) are regulated under Annex I of the International Convention for the Prevention of Pollution from Ships as implemented by the Act to Prevent Pollution from Ships and U.S. Coast Guard regulations found in 33 CFR 151.09. Vessels greater than 400 gross tons shall not discharge untreated oily bilgewater into waters subject to this permit. 213
