The New Zealand Environmental Protection Authority (EPA) is currently upgrading its quantitative risk assessment approach for hazardous material release applications. New Zealand EPA hazardous substances risk assessment upgrade, which is based on results from recent regulatory assessments such as the Agricultural and Horticultural Products Regulatory Review, intends to adopt the best available science, expedite application times, and better safeguard people and the environment.
The revisions only apply to release applications that require quantitative assessments and do not include containment clearances. The EPA seeks to reduce application delays and build more fit-for-purpose risk controls by implementing clearer, product-specific data criteria and using New Zealand-specific data. Furthermore, the new framework is consistent with worldwide regulatory standards, allowing applicants to follow the same procedures utilized in other global jurisdictions.
The modernization project is being rolled out in two main stages:
- Existing systems include: The EPA has successfully implemented an internal software, R statistical environment to do sophisticated data analysis. It has also established the public Bird Risk Calculator Tool, which allows applicants to learn about how the EPA currently assesses quantitative spraying risks to birds.
- What is coming next: Following project completion, a brand-new overarching risk assessment methodology will be provided to replace the 2022 framework. This will be accompanied by a set of new tools aimed at ecotoxicology (the effects on non-target species such as bees and aquatic life), toxicology (human health hazards, PPE needs, and restricted entrance intervals), and environmental destiny (predicting chemical concentrations in soil and water).
When completely implemented, these transparent resources will enable applicants to gain a better understanding of the assessment process, conduct preliminary testing on their own goods, and identify particular data that may be submitted in place of default models to produce more realistic risk profiles.
