This policy may be cited as the Environmental Protection (Air) Policy 2019.
This policy commences on 1 September 2019.
The dictionary in schedule 2 defines particular words used in this policy.
This policy applies to the air environment.
(1)The purpose of this policy is to achieve the object of the Act in relation to the air environment.See section 3 of the Act.(2)The purpose is achieved by—(a)identifying environmental values to be enhanced or protected; and(b)stating indicators and air quality objectives for enhancing or protecting the environmental values; and(c)providing a framework for making consistent, equitable and informed decisions about the air environment.
The environmental values to be enhanced or protected under this policy are—(a)the qualities of the air environment that are conducive to protecting the health and biodiversity of ecosystems; and(b)the qualities of the air environment that are conducive to human health and wellbeing; and(c)the qualities of the air environment that are conducive to protecting the aesthetics of the environment, including the appearance of buildings, structures and other property; and(d)the qualities of the air environment that are conducive to protecting agricultural use of the environment.
7Air quality objectives for indicators
(1)This section and schedule 1 state the air quality objectives to be achieved and maintained under this policy.(2)An air quality objective stated in schedule 1, column 3 for an indicator stated in column 1 and for a period stated in column 4 is stated for enhancing or protecting the environmental value stated in column 2 of the schedule for the objective.(3)An air quality objective stated in schedule 1, column 3 must be worked out as an average over the period stated in column 4 for the objective.(4)It is intended that the air quality objectives be progressively achieved as part of achieving the purpose of this policy over the long term.(5)This section does not apply to an air emission that may be experienced within a residence or workplace if the air emission is released within the residence or workplace.(6)In this section—workplace see the Work Health and Safety Act 2011, section 8.s 7 amd 2024 SL No. 186 s 4
8Management hierarchy for air emissions
(1)This section states the management hierarchy for an activity involving air emissions that affect, or may affect, an environmental value to be enhanced or protected under this policy.See section 35 of the Environmental Protection Regulation 2019.(2)To the extent that it is reasonable to do so, air emissions must be dealt with in the following order of preference—(a)firstly—avoid air emissions;using technology that avoids air emissions(b)secondly—recycle air emissions;re-using air emissions in another industrial process(c)thirdly—minimise air emissions;using technology, materials or industrial processes that minimise air emissions(d)fourthly—manage air emissions.•locating a thing that releases air emissions in a suitable area to minimise the impact of the air emissions•treating air emissions before release•dispersing air emissions to minimise the impact of the air emissions
The Environmental Protection (Air) Policy 2008, SL No. 441 is repealed.
