OILY WASTE SYSTEMS. For typical ship-to-shore connection
requirements, see Figure 3-8. Oily waste collection must be provided at all berths for
6.3 l/s (100 gpm.) Oily waste system requirements for selected ship classes are defined
in Appendix C. For ships not included in Appendix C, use data from a similar ship or
obtain the expected demand from NAVFAC CIENG or USACE.
The system is usually a fixed piping system. However, tank truck or
barges may be used for transient berths if allowed by the Activity. Ship waste oily
barges (SWOB) should not be used at submarine berths due to potential hull damage.
Design ships oily waste (bilge water) systems in accordance with MIL-HDBK-1005/9,
Industrial and Oily Wastewater Control. Also, refer to 40 CFR, Part 1700, Uniform
National Discharge Standards for Vessels of the Armed Forces, and to NAVSEA
S9593-BF-DDT-010, Oil Pollution Abatement System for ship design. Connection
locations for ships oily waste are defined in Appendix C. Refer to Chapter 2 for a
description of utility spacing requirements. In climates subject to freezing temperatures,
oily waste lines must be properly protected. Refer to Chapter 6.
Pierside and Barge Collection of Shipboard Oily Waste. Shipboard
oily waste must not be directly discharged to public waters. In many cases it is
unsuitable for discharge to a POTW. Requirements are: (1) provide full treatment to
direct discharge standards; or (2) provide pretreatment to reduce pollutants to
acceptable levels for municipal sewer discharge. Bilge wastes are normally the primary
influent (both in volume and contaminant concentration) to an oily waste treatment
system. Occasionally, compensating ballast water is discharged from ships and barges
directly overboard. As of this writing, Puget Sound, Washington activities are required
by the local regulatory agencies to collect compensating ballast water during ship's
refueling operations. This waste contains lower contaminant levels than bilge wastes
but usually requires treatment before disposal. Lastly, the designer should refer to the
Naval Facilities Engineering Service Center's (NFESC) Bilge and Oily Wastewater
as an alternative system for pollution prevention. Every project must
be evaluated on a project-by-project basis. The designer must consult with the
cognizant NAVFAC EFD/EFA OR USACE DISTRICT, the Activity, and the responsible
Environmental Engineers, both at the local level and at the NAVFAC EFD/EFA OR
USACE DISTRICT level.
