ARRPA Regulations, 1976 

Under the Agriculture and Related Resources Protection Act 1976 (ARRPA) Restrictions are imposed in different areas. These restrictions involve:

  1. use of volatile esters or approved low volatiile esters or other approved phenoxy amines or salts
  2. storage of volatile esters
  3. spray contaminated vehicles and
  4. permits to use approved phenoxy herbicides within a restricted area.

The use of any kind of ester formulations of phenoxy acid herbicides is prohibited.

The use of amine or salt formulations is permitted subject to prior written approval from the Director General of DAFWA.

The use of an approved low volatile ester is allowed.

Storage restrictions

The storage of any volatile ester of phenoxy acid is totally banned within 19km of the Geraldton post office. Storage beyond 19km but within 50km radius of the Geraldton Post Office requires prior written approval from the Director General of DAFWA.

Contamination restrictions: vehicles and open containers

No opened container of volatile esters or equipment or vehicle contaminated with these chemicals may be stored or parked. These restrictions do not apply to a moving vehicle or to approved low volatile esters.

Permit to spray with amine or salt

The spraying of an amine or salt form of a phenoxy acid herbicide within certain areas is subject to prior written approval from the Director General of DAFWA. To obtain approval to spray, a written application must be made setting out the following information:

  • approximate area to be sprayed
  • location of the area to be sprayed
  • the amine or salt form to be used
  • the method of spraying and the equipment to be used
  • the proposed date of spraying.
