Dust suppression season runs from September 2019 to March 2020.

If you want to apply a dust suppressant to a gravel road you must have a permit from Southland District Council. This costs $65.

We will supply you with two current signs indicating that the road surface is treated and advising drivers to proceed with caution. These signs will indicate to our roading contractors not to grade the treated section of road.

The kind of product you use to apply to the road once you have a permit from SDC is regulated by the regional council, Environment Southland.

Southland is one of the last regions in New Zealand that still allows application of used engine oil to gravel roads to suppress dust.

Used oil is considered a hazardous substance, so if you want to apply it to your road you’ll need to apply for a discretionary consent from Environment Southland. ES requires you to pay a deposit to cover the cost of processing the consent.

There are alternatives to used oil which are considered safer for humans and the environment and in some cases suppress dust mort effectively.  These include vegetable oil, HSNO-approved dust suppressant, Gravel Lock and OTTA Seal.

Applying these approved alternative products is a permitted activity and you do not require a consent from Environment Southland to apply them. However, you will still require a permit from Southland District Council.

We will not be able to issue your Dust Suppression Permit without confirmation from Environment Southland that your application complies with the rules.
