Under 33 CFR §151.05, which of the following correctly distinguishes 'domestic wastes' from 'graywater'?
- ✓ Domestic wastes are all types of wastes generated in accommodation spaces not covered by other MARPOL Annexes and do not include graywater, while graywater is specifically drainage from dishwater, shower, laundry, bath, and washbasin drainsCorrect
- B. Domestic wastes include graywater and all drainage from accommodation spaces including toilets and urinals, while graywater excludes drainage from cargo spaces only
- C. Domestic wastes are limited to food wastes and human waste from accommodation spaces, while graywater includes all liquid waste from accommodation and cargo spaces
- D. Domestic wastes and graywater are interchangeable terms under MARPOL Annex V as implemented by 33 CFR Part 151
Why A is correct
33 CFR §151.05 defines domestic wastes as all types of wastes not covered by other MARPOL Annexes generated in accommodation spaces, and expressly states that domestic wastes do not include graywater. Graywater is separately defined as drainage from dishwater, shower, laundry, bath, and washbasin drains, excluding drainage from toilets, urinals, hospitals, animal spaces, and cargo spaces.
