                TITLE 33--NAVIGATION AND NAVIGABLE WATERS
 
   CHAPTER I--COAST GUARD, DEPARTMENT OF HOMELAND SECURITY (CONTINUED)
 
PART 159--MARINE SANITATION DEVICES--Table of Contents
 
              Subpart C--Design, Construction, and Testing
 
Sec. 159.125  Visible floating solids: Type I devices.

    During the sewage processing test (Sec. 159.121) 40 effluent samples 
of approximately 1 liter each shall be taken from a Type I device at the 
same time as samples taken in Sec. 159.123 and passed expeditiously 
through a U.S. Sieve No. 12 as specified in ASTM E 11 (incorporated by 
reference, see Sec. 159.4). The weight of the material retained on the 
screen after it has been dried to a constant weight in an oven at 103 
C. must be divided by the volume of the sample and expressed as 
milligrams per liter. This value must be 10 percent or less of the total 
suspended solids as determined in accordance with 40 CFR Part 136 or at 
least 38 of the 40 samples.
    Note: 33 U.S.C. 1321(b)(3) prohibits discharge of harmful quantities 
of oil into or upon the navigable waters of the United States or 
adjoining shorelines or into or upon the waters of the contiguous zone.

Under 40 CFR 110.3 and 110.4 such discharges of oil include discharges 
which:
    (a) Violate applicable water quality standards, or
    (b) Cause a film or sheen upon or discoloration of the surface of 
the water or adjoining shorelines or cause a sludge or emulsion to be 
deposited beneath the surface of the water or upon adjoining shorelines. 
If a sample contains a quantity of oil determined to be harmful, the 
Coast Guard will not certify the device.
