Controlled Waste Tracking Forms (CWTF)
The City may also reject loads if the tracking form is not completed correctly or information is missing. To avoid this ensure these forms are filled out correctly.
 
If and when waste has come from a mine site and there is no specific address stated, the tenement number and shire locality must be listed along with the company and mine site name.
  • Note: the responsibility of identifying the type of waste lies with the Controlled Waste Carrier and if quoting unseen works, it is highly recommended that some kind of disclaimer is quoted to the waste generator in the event the waste is not what the generator is claiming and is rejected.
What happens if my load is rejected?
In the interest of protecting both the treatment plant and quality of the effluent discharged, operators will not accept any load that fails the initial assessment completed or any load that is suspected to not meet the acceptance criteria will be rejected. 

If a load is rejected:
  • A sample will be taken of the load that has been rejected and will be sent to a NATA accredited approved lab at the City’s expense
  • The results will be forwarded to the Controlled Waste Carrier. Note: any load that has failed the initial on site test may not be sent away for analysis. If requested a written explanation via email of why it was rejected may be supplied
  • If the results from the rejected load did meet the acceptance criteria the carrier may be reimbursed the difference in cost between disposal from the SBWWTP and the alternate disposal site
  • If the results from the rejected load did not meet the acceptance criteria any future loads from that site will only be accepted if results from NATA accredited lab confirm it now meets the acceptance criteria. See: What is our discharge criteria?
