TRADE WASTE AGREEMENT
between
The Bongo Better Brewing Company (Trading as the BBBC)
and
Southern Hunter Industrial Trade-Waste board
for
discharge of effluent from the pilot plant on Kooragang Island to the stormwater system.
Below are listed the acceptance standards for discharge of prohibited substances to the corporation's storm
water channels. The company listed above is listed as a major permit holder under this agreement, which
shall agree with all of the substance limitations as stated in the following clauses.
Substance(s)
Temperature
Limit
36ºC
Comments
Not to exceed (36ºC) thirty-six degrees
Celsius.
Discharge Rate
As determined appropriate by the
Corporation in view of the capacity of the
works in question.
Odour
Controls as may be deemed necessary by
the Corporation depending on
circumstances.
pH
6.5 to 8.5
Not to be less than 6.5 or greater than 8.5.
BOD5
20 mg/L
Biochemical Oxygen Demand (five day)
(organic carbon loading) concentration not
to exceed 20 mg/L.
Dissolved Oxygen
40%
Not less than 40% saturation regardless of
temperature of water.
Total Coliform
<10 CFU
/100mL
Less than 10 colony forming units per
100mL of sample.
Pesticides
100ppb
Chlorinated pesticides are not permitted
Total Suspended Solids
25 mg/L
Also called Non-Filterable Residue
concentration not to exceed 25mg/L.
Colour
TOG
Not noticeable at 100 dilutions.
10 mg/L
Total Oil and Grease. To be absent except
for stable dispersions containing not more
than 10 mg/L.
Notwithstanding the above, the discharge of prohibited substances to the Corporation's stormwater
system will be permitted only in exceptional circumstances and after the Applicant has received
permission in writing from the EPA.
It should be noted that because the contents of stormwater drains do not receive treatment prior to discharge
to receiving waters, approval for discharge to the Corporation's stormwater system will only be given under
exceptional circumstances with written permission from the EPA and the Corporation, but when this does
occur it will be subject to the following charges:



Permit Fees – As per fees listed in the Schedule of Fees and Charges.
Analytical Fees – As per fees for discharge to the Corporation's sewerage system.
Inspection Fees– As per fees for discharge to the Corporation's sewerage system for Major Permit
Discharger.
Please note that the following conditions apply to the discharge of waste water to the Corporation’s
sewer system.
Strength Fees
The discharge of trade wastewater to the sewerage system places an additional load on that system. This
additional load is created by both the concentration (strength) of the substances discharged, and their total
mass (weight). Trade waste strength charges are applied to cover the costs of this additional loading for
each individual customer according to the wastewater discharge.
Biochemical Oxygen Demand/Non-Filterable Residue
Fees will be charged based on treatment costs of the strength of waste where the sample results for BOD 5
are greater than 20mg/L or NFR is greater than 200 mg/L. The Corporation considers that this strength load
and additional costs are over that which would be incurred by acceptance of a similar quantity of purely
domestic sewerage.
Phosphorus Fee
Fees will be charged where the strength of phosphorus is greater than 12 mg/L, the deemed domestic
concentration of effluent discharged.
Heavy Metal Charge
Metals accumulate in the wastewater treatment bio-solid waste sludge. High levels of these metals degrade
the quality and re-use of these materials. The discharge to the environment is also restricted by the EPA
within the discharge licences with Southern Hunter Industrial Trade-Waste Board and the charging of load
based license fees. Charges are based on total mass of metals discharged to the Corporation's sewer.
Miscellaneous Charge
Fees shall be determined by the Corporation for each particular prohibited substance discharged and shall
be specified in the Permit.
