used, is likely to contain inflammable compound, which
shall therefore be intercepted before discharging into the

inflammable compound and shall be so located and
constructed to prevent fire or explosion. Drainage from
commercial garages and oil stations where automobile wash
racks are installed is also likely to contain mud and sand,
which shall be separated from the wastes before discharging
into the city sanitary sewer. Hence, the interceptor for
these wastes shall afford sufficient capacity for both
separating the oils and grease by flotation and the sand
and mud by settling.
1008.2 Where the wastes do not contain sand, mud or other
solid material and inflammable compounds only are to be
separated, the interceptor shall have a minimum capacity of
15 cubic feet with a minimum effective depth of 3 feet; and
shall be provided with a vent and manhole with tightly
fitting cover.
1008.3 For drainage from commercial garages or other places
where wastes are likely to contain sand, mud, or other
solid material in addition to oil, grease, or other
inflammable compounds, a minimum capacity of 50 cubic feet,
Ordinance No. 4995
Page 17
with a minimum effective depth of 3 feet, shall be provided

be of poured, reinforced concrete not less than 5 inches
thick.
1008.6 Subsections 1008.1 through 1008.5 of this section
shall apply except for manufactured or prefabricated
concrete interceptors that comply with approved applicable
standards. See "Exhibit A. Commercial Mud Trap"39.
1008.7 For details, see diagram marked "Exhibit B. Mud Trap
or Inflammable Waste Interceptors"l.
Scction 1012, Cr asc Interceptors for Commercial Kitchens, is
amcndcd by adding thc following subsections:
1012.1 Any liccnscd fo d establishment shall install and
maintain an outside intcrccptor and shall have all kitchen
equipment discharge through such intcrccptor. The drawing
