Issuing Permissions for Vertebrate Toxic Agents.


In order to use certain VTAs and other hazardous substances, operators must apply for permission, and they have a legal obligation to comply with any conditions in the permission.

Permissions are required when these VTAs and other hazardous substances are:

  • intended to be applied or used in a catchment area from which water is drawn for human consumption, or
  • applied in any other area where a risk to public health may be created.

When issuing a permission, there is discretion to apply conditions to ensure that public health risks are assessed and managed effectively. These guidelines provide practical advice setting conditions on permissions to use VTAs and other hazardous substances, using Model Permit Conditions.
