1. Use of used oil
The use of used oil as a suppressant requires a resource consent from Environment
Southland. Please refer to Rule 17 of Environment Southland’s Proposed Water and Land
No permit will be approved by the Gore District Council for the use of used oil unless this
application is accompanied with an approved resource consent decision from Environment
Southland or a contractor approved by Environment Southland.
2. Road conditions
Suppressant is to be sprayed only when the road is well formed and without potholes.
The optimum time to apply suppressant is just after the grader has been, when the road is
well shaped and still has a high crown.
Details of when your road is to be graded can be obtained from the Council.
3. Gravel / seal margin
Stop application of the suppressant a minimum of 5m from the permitted length to provide
a transitional area. This is to prevent suppressant being tracked onto the sealed surface.
4. Application rates and control of spraying
Please ensure suppressant application is well controlled and evenly spread, and that any
surplus does not run into drainage channels or water courses.
Follow manufacturers specifications to ensure correct application rate.
It a product is sprayed too thickly it is likely to case ponding and splash onto other vehicles.
Previous applications must be considered to avoid excess suppressant on the road.
Temporary traffic control, in accordance with a traffic management plan approved by the
Council, shall be used during spraying.
The suppressant should not be applied if rain is forecast within 48 hours.
The applicant is required to have public liability insurances to the minimum value of $1
million. Evidence of this insurance is required before any application is approved.
