Agriculture Victoria in grain dumping caution

HVNL mass compliance responsibility prompts risk of unlawful discarding

Government agency Agriculture Victoria (AV) reminds operators to comply with relevant regulations as a strong crop harvest last year results in more grain and cereal being moved around the state.

With the increased movement, there is potential risk that some transporters are concerned about having excess weight and compliance with the Heavy Vehicle National Law (HVNL), which is considered a breach of their Chain of Responsibility (COR), AV grains industry biosecurity officer Jim Moran says.

This may result in grain dumping in unauthorised areas, which AV encourages witnesses to report.

"Agriculture Victoria is keen for everyone to be aware that grain dumping is an illegal activity which should be reported to the Environment Protection Authority (EPA).

"Grain may be dumped in smaller quantities at roadsides by drivers, who have delivered to seaports or other grain receival sites and are unable to find suitable facilities to sweep out trucks and trailers, before backloading with fertiliser or other commodities from a different facility.

"Reports will be further investigated, cleaned up and referred to the relevant agency depending on the circumstances.

"Illegal grain deposits are often found along the transport corridors to and from ports.

"Grain dumping provides an ideal pathway for hitchhiker pests – insects and diseases – to make their way from a busy seaport to a farm where they can then become established in the grain production system.

"Dumped grain can be a food source for birds and vermin such as mice and pest animals which build in number and damage nearby crops and grain storages.

"As the grain germinates it provides an ideal green-bridge for the early build-up of fungal diseases such as rusts which causes substantial yield loss."

Moran encourages growers and industry to take action to reduce the incidence of grain being dumped on the roadside.

To comply with load limits, a more accurate measure of weight should be undertaken at loading. This can include:

  • installing a permanent or temporary on-farm weighbridge
  • access to a nearby off-site weighbridge
  • using on-board, over the axles or suspension-mounted vehicle scales and other visual methods that are proven to reduce the incidence of overloading (and comply with COR).

"Ensuring trucks come clean and go clean is also vital," Moran says.

"While this is an ongoing matter between the grains industry and receival sites if there is grain left over that needs to be disposed of, do it in a manner that does not pose a biosecurity risk.

"It can be burned, buried or bagged and reused, perhaps as livestock feed if it is uncontaminated."

The grains industry, through the 2021 Grain Trade Australia (GTA) Transport Code of Practice, supports this practice through recommended biosecurity protocols.

"There should be no residual grain left in the trailer that then needs to be dumped prior to picking up a new delivery. If a truck turns up empty but not clean, it is possible residual grain has just been dumped," Moran says.

"Ask your grain freighters if they comply with the GTA Code of Practice.

"Growers should also have a designated clean-down area which can be monitored regularly for volunteer plants, weeds or pests.

"Biosecurity is maintained if everyone along the grain supply chain follows their Chain of Responsibility and implements good hygiene practices."
