What is your classification?

We consider deemed discharges to be a negligible risk. You must follow the conditions in the Trade Waste Bylaw 2013, but you do not need a trade waste agreement.

What is deemed trade waste?

It is any trade waste discharged which:

• is a result of an activity listed in Schedule 1 of the bylaw and meets our controlled substance standards, and
• is not conditional trade waste and does not have any of the prohibited characteristics listed in Schedule 3 of the bylaw, and
• is less than 10 cubic metres per day and less than 0.5 litres per second.

Your responsibilities

You must meet the pre-treatment requirements listed in Schedule 1 of the bylaw, and treat your waste to our standards for controlled substances.

If the pre-treatment system is not able to meet those standards, we will classify your waste as conditional, and you must not discharge it without a trade waste agreement.

We consider conditional discharges to be a higher risk. In general, higher-risk customers will have robust systems to manage their trade waste and will undertake more frequent monitoring.

What is conditional trade waste?

It is any trade waste discharged:

• as a result of an activity listed in Schedule 2 (page 21) of the Auckland Trade Waste Bylaw 2013 and which complies with our controlled substance standards, unless authorised in a trade waste agreement

or

• from trade premises (including activities listed in Schedule 1 [page 18] of the bylaw) where the discharge exceeds 10 cubic metres per day or exceeds 0.5 litres per second

or

• which we determine to be conditional under Clause 7 (page 7) of the bylaw.

Your responsibilities

You must:

• follow the regulations set out in the bylaw
• have a trade waste agreement setting out your discharge limits and monitoring criteria. Learn more and apply for an agreement
• comply with our controlled substance standards unless the agreement authorises an exemption.
