2.2.5
Identification Plates
**************************************************************************
NOTE: In a salt water environment substitute
acceptable non-corroding metal such as but not
limited to copper-nickel, 316 stainless steel, or
monel. Aluminum is unacceptable. Nomenclature (or
system identification) to be established by designer.
**************************************************************************
Provide [anodized aluminum] [_____] identification and instruction plates
and stamp necessary data. Securely affix plates, in prominent location, to
separator with nonferrous screws or bolts of not less than 3 mm 1/8 inch in
diameter. Nomenclature shall be [_____].
2.2.6
Instruction Plates
Instruction plates shall describe special or required procedures to operate
and service equipment, and shall include warnings of hazardous procedures
and notice of safety and health requirements. Plates shall be durable and
legible throughout equipment life.
2.2.7
Warning Sign
On entrances to the separator (and entrances to the vault) place a
permanent sign which states the following: "DO NOT ENTER separator ( OR
VAULT ) OR PERFORM HOT WORK ON OR IN separator UNTIL THE ATMOSPHERE HAS
BEEN TESTED AND CERTIFIED GAS FREE AND SAFE."
2.3
INLET COMPARTMENT
**************************************************************************
NOTE: Where a separate sedimentation basin has been
provided the volume of the inlet compartment may be
reduced. If total solids are less than 100 mg/L,
these elements may be eliminated after adequate
benchscale testing has been completed to support
this conclusion. Designer shall indicate run of
solids removal line from outlet nozzle to a point
above grade.
**************************************************************************
Provide inlet compartment of sufficient volume to effectively reduce
influent [suspended] [settleable] solids and dissipate energy. Use inlet
compartment that provides a minimum of 45 minutes detention ahead of the
oil coalescing compartment. Provide nonclogging flow distributor and
energy dissipator device [and the primary solids collection hopper as
specified in paragraph entitled "Reduction of Solids"]. Locate
[adjustable, primary surface oil overflow weir and] sample ports as
recommended by the manufacturer.
2.4
OIL SEPARATION COMPARTMENT
2.4.1
General
The maximum surface loading rate for the oil separation compartment shall be
[___] gallons per day per square foot [
] liters per square meter per
day). The separator will also provide a minimum detention time within the
oil separation compartment of [ ][45] minutes at design flow. Detention
