Appendix C - Stormwater Management Plan

‘Stormwater discharge quality Is < 1.86 mg/ hydrocarbon

content exceeding the Environmental Protection Agency

(E.PA.) requirements of 10mg/l hydrocarbon content.

Test sampling access: Field test discharged samples are

taken from sampling point and analysed by NATA 4
accredited laboratories.

    
 

Mat NTENANCE
Designed far high performance and low maintenance over a long life span

© Visible oils (TPH) are skimmed from the surface of the water level

« Easy and safe to access and clean, with access shafts positioned on
all chambers.

¢ No entering of the unit is required

¢ Not mandatory for the unit to be cleaned every 3 months.

© Only oils, sediment and gross pollutants need to be removed,
All stormwater does not require removal

© The cylindrical design ensures sediment collects easily on the floor
of the chambers effecting easy, quick removal. There are no square
corners or unreachable cavities and recesses.

© Waste is removed by a vacuum loading truck, (Suction truck)

The probe is freely suspended in the probe protection tube
in the separator at the correct level. When the ail-layer or
depth of hydrocarbons reaches the predetermined level, the
top of the probe will be immersed in the oil, breaking the
circuit and activating the alarm. It is intrinsically ‘fail-safe’
systern providing complete assurance that is operative. If a
fault occurs it will be signaled immediately.

SPEL® PURACEPTOR tanks contain an immersed inlet
dip pipe to extinguish flames and prevent inflammable
vapours form passing through to the drainage system,
Complies with Section 6.3.4 of BS EN 858.1.2006.

‘SPEL PURACEPTOR can withstand temperatures of up
to 140°C.

   

The AUTOMATIC CLOSURE DEVICE (A.C.D.) is a precisely
\ engineered device comprising a water-buoyant ball
that is sensitive to any change in the water density as a
consequence of light liquids build up, thereby automatically
activating a process of depressing the A.C.D. to SHUT OFF
the separator, preventing pollutants from discharging to
drains and waterways.

SPEL PURACEPTOR Class 1 separators
incorporate coalescer units. They
consist of a quality stainless steel
mesh container with an adjustable
handle and high volume reticulated
foam insert.

 
 
 
 
 
  
 
 
 
 
 
   

SPEL @ PURACEPTOR units are glass reinforced plastic
vessels made by the technical advanced chop hoop filament
winding process (patented) producing circumferential and
longitudinal strength complying with AS 2634-1983 for tank
design,

  
 
   
   
   

The coalescer unit is mounted in

the second chamber, providing

a coalescence process for the
separation of smatler globules of light
liquid pollutants before final discharge
to stormwater.
