The EPA has released revised State Guidelines for the treatment and reuse of biosolids, publishing the Tasmanian Biosolids Reuse Guidelines, June 2020 on the EPA website and alerting key stakeholders of their recent availability.
The Guidelines provide details on the treatment, testing and classification requirements for sewage sludge and biosolids in Tasmania, as well as providing guidance on management obligations to ensure the safe beneficial reuse of this material.
They have direct practical implications for waste transporters and contractors, and provide important information and advice to consultants, councils and other authorities.
Any biosolids handling, treatment, processing or application activities being undertaken in accordance with Regulation 19 of the Environmental Management and Pollution Control (Waste Management) Regulations 2020 must do so in accordance with these Guidelines.
The Guidelines are referenced in the Approved Management Method for Biosolids Reuse and their requirements have regulatory implications, and may be specifically referenced, in authorisations and notices in respect to sewage sludge and biosolids handling.
The 2020 Guidelines are an update of the previous 1999 version and are the product of several years work by EPA Tasmania, involving collaboration with State agencies and consultation with key stakeholders, with contributions made to both the review and subsequent drafts.
EPA Tasmania staff sought input to the Guidelines from within DPIPWE, including Analytical Services Tasmania, Biosecurity Tasmania and Tasmanian Institute of Agriculture, as well as the Department of Health, University of Tasmania and from the Australian New Zealand Biosolids Partnership (ANZBP).
The Guidelines underwent an extensive stakeholder consultation process involving groups such as TasWater, various transporters, processors and potential end users; and government agencies representing potential end users, such as Sustainable Timber Tasmania, Tasmanian Farmers and Graziers Association, and Local Government of Tasmania on behalf of councils.
The old Guidelines required significant overhaul to reflect the latest research and literature on biosolid reuse as the basis of the core treatment requirements of biosolids.
Amongst other improvements, the new Guidelines provide an updated list of contaminants that need testing, and the management requirements for biosolids handling have been rewritten.
The Approved Management Method for Biosolids Reuse (the AMM) has also been updated to reflect the new Guidelines and the Environmental Management and Pollution Control (Waste Management) Regulations 2020.
