Dear Sir,
Please find following information in regards to Councils concerns regarding any proposed connection
of treatment devices/sumps from the refuelling area into the stormwater disposal system.

Envirotank are the Australian distributors and manufacturers of oil water separators under license
from “Premier Tech Aqua” and they are compliant to all the clauses of the British Standard – EN858‐
1:2002(E) and specifically achieves the discharge maximum of less than 5ppm of light hydrocarbons
and captures in excess of 95% TSS, silts, solids and organic matter.
The site specific stormwater treatment solution for the under canopy and tanker off‐loading areas
of Lot 21 RP 72829, Lot 1 RP 131598 will be a Clereflo CCS20‐40 full retention separator (No By‐Pass)
Our solution of the Clereflo CCS20‐40 full retention separator (No By‐Pass) and has a full retention
capacity of at least 8kL of light hydrocarbons.
Accordingly the proposed unit is fitted with the following,
      Automatic closure device (ACD) on outlet.
      Monitored electronic overfill alarm system.
      Wet sealed entry to prevent back flushing and flame access to separator.

Therefore the requirements of your Planning Permit No. OPW20/0108 MCU19/0089 being that in a
100 year flood event with 300mm of flood water above the FL of the forecourt the separator will
fully retain its full contents of light hydrocarbons, silts, solids and any organic matter will be
achieved.
