• Approved Organisations shall only show the 30 percent of the total expenditure that is eligible for funding assistance in their transport programmes.
• The 30 percent component of the total cost of cleaning on state highways in urban areas An area within a permanent speed limit of less than or equal to 70 km/h. is to be funded within the state highway maintenance programme The total of the organisation's approved maintenance, operations and renewal activities. .
