5. Sampling, Testing and Monitoring
5.4.1 Monitoring for compliance
The Council is entitled to monitor and audit any Trade Waste discharge for compliance. Whether for a Permitted Discharge or a conditional Consent discharge monitoring may be carried out as follows:
- The Council or its authorised agent will take the sample and arrange for this sample to be analysed in accordance with S. 5.3; and
- The sampling procedure will be appropriate to the Trade Waste and the analysis; and
- The Council will audit the sampling and analysis carried out by a self-monitoring Trade Waste discharger. Analysis will be performed by an Approved laboratory; and
- The Council will audit the sampling and analysis carried out by an Analyst. Analysis will be performed by an Approved laboratory; and
- The Council will audit the Trade Waste Consent conditions including any Management Plans.
At the discretion of the Council all costs of monitoring shall be met by the discharger either through direct payment to the laboratory or to the Council.
5.4.2 Sampling methodology
Normally a single grab or composite sample is sufficient. If required the grab or composite sample can be split equally into three as follows:
- One portion of the sample goes to the Trade Waste discharger for appropriate analysis and/or storage; and
- A second portion of the sample shall be analysed at a laboratory Approved by the Council; and
- A third portion of the sample is retained by the Council for 20 Working Days, for additional analysis if required.
Due consideration will be applied to any changes that could occur in retained Trade Waste samples and provisions to mitigate against changes will be adopted where practicable.
In all cases the samples shall be handled in an appropriate manner such that the Characteristics being tested for are, as far as reasonably possible, preserved.
All samples shall be preserved, handled, transported and delivered to an Approved laboratory according to best possible practice and Approved standards.
NOTE: Please refer to Section 7 of this Bylaw for detailed sampling procedures.
5.4.3 Tankered wastes
Tankered Wastes shall not be discharged into the Council’s Sewerage System by any Person or Consent Holder not compliant with the Liquid and Hazardous Wastes Code of Practice.
The Council may accept Tankered Wastes for discharge at an Approved location. Tankered Wastes shall:
- Be transported by a Consent Holder to discharge domestic septic tank or industrial wastes; and
- Have material safety data sheets (MSDS) or sample analysis supplied to the Council detailing the contents of any non-domestic waste; and
- Be tested to determine their character if the contents of the waste are not known. Specialist advice on Pre-treatment or acceptance may be required. The cost of all testing and advice shall be borne by the Consent Holder; and
- Not be picked up and transported to the disposal site until appropriate arrangements and method for disposal have been determined by the Council; and
- To prevent cross-contamination between tanker loads, the tanker shall be thoroughly washed prior to collecting a load for disposal into the Sewerage System; and
- Loads that have not been consented for disposal shall not be picked up and transported to the Sewerage System for disposal unless appropriate prior arrangements have been made with the Council; and
- Loads with Hazardous substances that have not been specific approval, shall not be accepted; and
- Loads with characteristics that breach those as set out in the Trade Waste Consent are not acceptable unless specifically approved by the Council; and
- Costs for acceptance and treatment of tankered waste shall be invoiced to the consented discharger as specified in Schedule 1C of this Bylaw; non-payment of which forfeits the right to continue to discharge tankered waste into the Sewerage System; and
- Have 24 hours notice given for the disposal of wastes other than those sourced from domestic septic tanks; and
- Loads only accepted during working hours or working days, or as advised by the Council;
Any Person illegally disposing of, or causing to be disposed, Tankered Waste either by incorrect disclosure of contents (Characteristics and/or amount) or dumping into the Council; Sewerage System other than the prescribed location will be in breach of the Bylaw.
5.4.4 Disinfected/super chlorinated water
Any water used during the repair and construction of water mains shall be de-chlorinated prior to the discharge into the Sewerage System. Application for a Temporary Discharge Consent shall be made. Such water shall not be disposed of to Stormwater or adjacent water courses without appropriate Approvals.
