Part 5 - Liquid Trade Waste

This bylaw encourages the removal of trade waste from our wastewater systems in order to reduce costs to the ratepayer.

The Council's wastewater systems, like most town and city systems, were designed to handle domestic wastewater. While most of the wastewater the Council treats is domestic in nature, some industries can produce wastes that take up a significant portion of our treatment facilities, known as trade waste. Trade waste is any liquid that is discharged to the wastewater system from commercial, industrial, manufacturing or trade premises resulting from any processes or operations. The unpredictable nature of trade waste can have a significant adverse impact on the wastewater systems and as such the operational costs of the systems themselves.

In 2011 the Council undertook a public consultation process on the implementation of a Trade waste bylaw. Under this bylaw the Council assessed the wastes discharged into the sewer that are generated as part of a commercial process. We have developed a model to calculate the cost to treat wastewater so that the costs are shared more equitably between domestic and commercial users. To see these fees and charges, go to our Schedule of Fees and Charges:Trade Waste webpage.

Notwithstanding the above, the Council retains the right to review the conditions at an earlier time. The reasons for such an earlier review could include:
(A) The level of Consent Holder compliance, including any accidents including spills or process mishaps.
(B) Matters pertaining to the Council’s resource consents for the Sewerage System.
(C) Matters pertaining to the Council’s environmental policies and outcomes.
(D) New control and treatment technologies and processes.
(E) Any of the matters outlined in section 503.
(F) Matters pertaining to the Council’s legal obligations.

(b) In all other cases the term of a Conditional Trade Waste Consent should not exceed two years;
(c) In all cases where either the Consent Holder or the owner of the Premises changes, or there is a change of use, a new application for a Conditional Trade Waste Consent shall be made. It shall be the responsibility of the Consent Holder to lodge the new application; and
(d) The conditions on resource consents for the Sewerage System and the residuals from it change.

502.9 Technical review and variation
502.9.1

The Council at any time may require a Person undertaking a Permitted Discharge to apply for a Consent in accordance with 502.8.1.

502.9.2

The Council may at any time during the term of a Trade Waste Consent, by written notice to the Consent Holder (following a reasonable period of consultation), vary any condition to such an extent as the Council considers necessary following a review of the technical issues considered when setting conditions of Consent. This is due to new information becoming available or to meet any new resource consent imposed on the discharge from the Council’s treatment plant, or with any other legal requirements imposed on the Council.

502.9.3

A Consent Holder may at any time during the term of a Consent, by written application to the Council, seek to vary any condition of Consent, as provided for in 502.7 of this bylaw.

502.10 Cancellation of the right to discharge
502.10.1 Suspension or cancellation on notice

The Council may suspend or cancel any Consent or right to discharge at any time following 20 Working Days’ (during which consultation has occurred) notice to the Consent Holder or Person discharging any Trade Waste:
(a) For the failure to comply with any condition of the Consent;
(b) For the failure to maintain effective control over the discharge;
(c) For the failure to limit in accordance with the requirements of a Consent the volume, nature, or composition of Trade Waste being discharged;
(d) In the event of any negligence which, in the opinion of the Council, threatens the safety of, or threatens to cause damage to any part of the Sewer System or the treatment plant or threatens the health or safety of any Person;
(e) If any occurrence happens that, in the opinion of the Council, poses a serious threat to the environment;
(f) In the event of any breach of a resource consent held by the Council issued under the Resource Management Act 1991;
(g) Failure to provide and when appropriate update a Management Plan as required for a conditional Consent;
(h) Failure to follow the Management Plan provisions at the time of an unexpected, unscheduled or accidental occurrence;
(i) Failure to pay any charges under this Part of the bylaw; or
(j) If any other circumstances arise which, in the opinion of the Council, render it necessary in the public interest to cancel the right to discharge. If any process changes require more than 20 Working Days, reasonable time may be given to comply with the Consent conditions.

502.10.2 Summary cancellation

Further to 502.10.1 any Trade Waste Consent or discharge may at any time be summarily cancelled by the Council on giving to the Consent Holder or Person discharging written notice of summary cancellation if:
(a) They discharge any Prohibited substance;
(b) The Council is lawfully directed to withdraw or otherwise to terminate the Consent summarily;
(c) They discharge any Trade Waste unlawfully;
(d) If the continuance of discharge is, in the opinion of the Council, a threat to the environment or public health; -
(e) If the continuance of discharge may, in the opinion of the Council, result in a breach of a resource Consent held by the Council; or (f) In the opinion of the Council the continuance of the discharge puts at risk the ability of the Council to comply with conditions of a resource Consent and/or requires identified additional treatment measures or costs to seek to avoid a breach of any such resource Consent.


503 TRADE WASTE APPROVAL CRITERIA

503.1 Pre-treatment

The Council may approve a Trade Waste discharge (see Appendix D for appropriate form) subject to the provision of appropriate Pre-treatment systems to enable the Person discharging to comply with this part of the bylaw. Such Pre-treatment systems shall be provided, operated and maintained by the Person discharging at their expense.

Refuse or garbage grinders, and macerators shall not be used to dispose of solid waste from Trade Premises to the Sewerage System unless Approved by the Council.

The Person discharging shall not, unless Approved by the Council, add or permit the addition of any potable, Condensing, Cooling Water or Stormwater to any Trade Waste stream in order to vary the level of any Characteristics of the waste.

NOTE – Condensing and Cooling Water should not be discharged as of right to a Stormwater drain or natural waterway without the Consent of the appropriate authority.

503.2 Mass limits

A Conditional Trade Waste Consent to discharge may impose controls on a Trade Waste discharge by specifying Mass Limits for any Characteristic.

Mass Limits may be imposed for any Characteristic. Any Characteristic permitted by Mass Limit shall also have its Maximum Concentration limited to the value scheduled unless approved otherwise.

When setting Mass Limit allocations for a particular Characteristic the Council shall consider:
(a) The operational requirements of and risk to the Sewerage System, and risks to occupational health and safety, public health, and the ultimate receiving environment;
(b) Whether or not the levels proposed pose a threat to the planned or actual beneficial reuse of Biosolids or Sewage Sludge;
(c) Conditions in the Sewerage System near the Trade Waste discharge point and elsewhere in the Sewerage System;
(d) The extent to which the available industrial capacity was used in the last financial period and is expected to be used in the forthcoming period;
(e) Whether or not the applicant uses Cleaner Production techniques within a period satisfactory to the Council;
(f) Whether or not there is any net benefit to be gained by the increase of one Characteristic concurrently with the decrease of another to justify any increased application for industrial capacity;
(g) Any requirements of the Council to reduce the pollutant discharge of the Sewerage System;
(h) How great a proportion the mass flow of a Characteristic of the discharge will be of the total mass flow of that Characteristic in the Sewerage System;
(i) The total mass of the Characteristic allowable in the Sewerage System, and the proportion (if any) to be reserved for future allocations; and
(j) Whether or not there is an interaction with other Characteristics which increases or decreases the effect of either Characteristic on the Sewer reticulation, treatment process, or receiving water (or land).


504 SAMPLING, TESTING AND MONITORING

504.1 Flow metering
504.1.1

Flow metering may be required by the Council:
(a) On discharges when there is not a reasonable relationship between a metered water supply to the Premises, and the discharge of Trade Waste;
(b) When the Council will not approve a method of flow estimation; or
(c) When the discharge represents a significant proportion of the total flow/load received by the Council.

504.1.2

The Consent Holder shall be responsible for the supply, installation, reading and maintenance of any meter required by the Council for the measurement of the rate or quantity of discharge of Trade Waste. These devices shall be subject to the Approval of the Council, but shall remain the property of the Consent Holder.

504.1.3

Records of flow and/or volume shall be available for viewing at any time by the Council, and shall be submitted to the Council at prescribed intervals by the Consent Holder in a format Approved by the Council.

504.1.4

Meters shall be located in a position Approved by the Council which provides the required degree of accuracy and should be readily accessible for reading and maintenance. The meters shall be located in the correct position according to the manufacturer’s installation instructions.

504.1.5

The Consent Holder shall arrange for in situ calibration of the flow metering equipment and instrumentation by a Person and method Approved by the Council upon installation and at least once a year thereafter to ensure its performance. The meter accuracy should be ±10 % but with no greater a deviation from the previous meter calibration of ±5 %. A copy of independent certification of each calibration result shall be submitted to the Council.

504.1.6

Should any meter, after being calibrated, be found to have an error greater than that specified in 504.1.5 as a repeatable measurement, the Council may make an adjustment in accordance with the results shown by such tests back-dated for a period at the discretion of the Council but not exceeding 12 months, and the Consent Holder shall pay or be credited a greater or lesser amount according to such adjustment.

504.2 Estimating discharge
504.2.1

Where no meter or similar apparatus is required, the Council may require that a percentage of the water supplied to the Premises (or other such basis as seems reasonable) be used for estimating the rate or quantity of flow for the purposes of charging.

504.2.2

Should any meter be out of repair or cease to register, or be removed, the Council shall estimate the discharge for the period since the previous reading of such meter, (based on the average of the previous 12 months charged to the Person discharging) and they shall pay according to such estimate. Provided that when by reason of a large variation of discharge due to seasonal or other causes, the average of the previous 12 months would be an unreasonable estimate of the discharge, then the Council may take into consideration other evidence for the purpose of arriving at a reasonable estimate, and the Person discharging shall pay according to such an estimate.

504.2.3

Where in the opinion of the Council, a meter has been tampered with, the Council (without prejudice to the other remedies available) may declare the reading void and estimate discharge as provided above.

504.3 Sampling and analysis
504.3.1

As determined by the Council sampling, testing and monitoring may be undertaken to determine if:
(a) A discharge complies with the provisions of this bylaw;
(b) A discharge is to be classified as a Permitted, Conditional, or Prohibited, refer to 502.1;
(c) A discharge complies with the provisions of Schedule 1A for Permitted Discharge and any Consent to discharge; and
(d) Trade Waste Consent charges are applicable to that discharge.

504.3.2

The taking, preservation, transportation and analysis of the sample shall be undertaken by an Authorised Officer or agent of the Council, or the Person discharging in accordance with a method specifically Approved by the Council, taking into consideration accepted industry standard methods. The Person discharging shall be responsible for all reasonable costs. Where a dispute arises as to the validity of the methods or procedures used for sampling or analysis, the dispute may be submitted to a mutually agreed independent arbitrator.

504.3.3

All Authorised Officers or authorised agents of the Council, or any Analyst may enter any Premises believed to be discharging Trade Waste at any time in order to determine any Characteristics of any actual or potential discharge by:
(a) Taking readings and measurements;
(b) Carrying out an inspection; and/or
(c) Taking samples for testing, of any solid, liquid, or gaseous material or any combination or mixture of such materials being discharged.

Authorisation for entry to Premises is given under the Local Government Act and entry shall be in compliance with the health and safety policies of that particular site.

504.4 Monitoring
504.4.1 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:
(a) The Council or its authorised agent will take the sample and arrange for this sample to be analysed in a laboratory accredited by International Accreditation New Zealand (IANZ) and approved by the Council by industry standard analytical methods;
(b) The sampling procedure will be appropriate to the Trade Waste and the analysis;
(c) The Council will audit the sampling and analysis carried out by a self monitoring Trade Waste discharger. Analysis shall be performed by an IANZ accredited, approved laboratory. Inter laboratory checks shall be a part of this process; (d) The Council will audit the sampling and analysis carried out by an Analyst. Analysis shall be performed by an IANZ accredited, approved laboratory. Inter-laboratory checks shall be a part of this process; and
(e) 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.

504.4.2 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:
(a) One portion of the sample goes to the Trade Waste discharger for appropriate analysis and/or storage;
(b) A second portion of the sample shall be analysed at a laboratory Approved by the Council;
(c) A third portion of the sample is retained by the Council for 30 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.

504.4.3 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:
(a) Be transported by a Consent Holder to discharge domestic septic tank or industrial wastes;
(b) Have material safety data sheets (MSDS) supplied to the Council detailing the contents of trade waste;
(c) 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;
(d) Not be picked up and transported to the disposal site until appropriate arrangements and method for disposal have been determined by the Council;
(e) 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
(f) Have 24 hours notice given for the disposal of wastes other than those sourced from domestic septic tanks.

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’s Sewerage System other than the prescribed location will be in breach of this Part of the bylaw.

504.4.4 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.
