1.1 These requirements cover stationary gravity or pump fed abcveground and underground,
atmospheric type oil/water separator systems intended to remove oil, having a specific gravity of 0.83 -
0.94 at 15℃ (59℉), suspended in water from rainwater runoff or normal washdown of streets, highways,
and parking lots at an inlet rate not exceeding the marked maximum infiuent concentration and flew rate.
1.2 These requirements cover gravity or pump fed oil/water separator systems having capacities of 60 to
50,000 gallons (227 - 189,270 L) total.
'1.3 Oil/water separators are intended for installation and use in accordance with the Flammable and
Combustible Liquids Code, NFPA 30; the Automotive and Marine Service Station Code. NFPA 30A; and
the Standard for the Installation of Oil-Burning Equipment, NFPA 31, or other National or State codes for
Oil/Water Separation equipment installation and use.
1.4 Oil/water separator systems covered by these requirements are fabricated, inspected, and tested for
leakage before shipment from the factory as completely assembled units, or with instructions for field
assembly of minor components.
1.5 These requirements do not cover oil that has been physically emulsified (other than by a feed pump),
chemically emulsified or dissolved.
1.6 These requirements do not cover liquid level devices, overpressure devices, heaters, pumps,
monitors, shutoff valves, or other individual mechanical or electrical components which are not an integral
part of, or are recommended for use with, the oil/water separator system. The requirements for these
devices are covered under separate standards as referenced in Appendix A.
1.7 These requirements do not cover oil/water separator systems intended for collection or washdown of
large concentrated spills from tankers or other bulk carders.
1.8 These requirements do not cover oil/water separator systems intended to be installed in mobile
vehicles or vessels.
1.9 These requirements do not cover oil/water separator systems for installation in hazardous chemical
locations, or for use with hazardous chemicals.
1.10 These requirements do not cover oil/water separator systems for use with oil outside the range of 0
- 35℃ (32 - 95℉).
1.11 These requirements do not cover oil/water separator systems for marine use, or washdown with salt
water, as covered under the Standard for Oily Water Separating Equipment and Oil Content Meters - UL
1504.
1,12 These requirements do net cover the ability of the oil/water separator systems to perform or operate
with debris or suspended solids in the oil/water mixture.
1.13 The term "separator" as used in this Outline refers to the complete oil/water separating systems, or
any part thereof covered by this Outline unless specifically noted otherwise.
