Regulation 32(1): substituted, on 23 September 2004, by regulation 10 of the Hazardous Substances (Classes 6, 8, and 9 Controls) Amendment Regulations 2004 (SR 2004/250).
33 Ability to set environmental exposure limit
(1)
An environmental exposure limit may be set for a class 9 substance by the Authority for 1 or more environmental media if the environmental medium relates to an exposure route through which organisms that live in an aquatic environment, terrestrial vertebrates, terrestrial invertebrates, or organisms that live in the soil may be exposed to the substance.
(2)
An environmental exposure limit set for a class 9 substance must be derived from an assessment of the ecotoxicological data available for the substance.
(3)
An environmental exposure limit must be expressed as a concentration of the substance in an environmental medium.
(4)
If a substance is a mixture, an environmental exposure limit may be set for the substance or 1 or more components of the substance, and the environmental exposure limit must be derived from an assessment of the ecotoxicological data available for the mixture or 1 or more components of the mixture.
34 Environmental exposure limit may be exceeded for rapidly degradable substance
(1)
If an environmental exposure limit is set in accordance with regulation 33 for a rapidly degradable substance, the Authority may adjust the environmental exposure limit in the circumstances specified by the Authority.
(2)
The adjusted environmental exposure limit—
(a)
must not be more than 10 times the value of the environmental exposure limit; and
(b)
is to be treated as the environmental exposure limit in the circumstances specified by the Authority.
35 Methods for setting environmental exposure limit
An environmental exposure limit must be set—
(a)
by adopting a value that represents a concentration of the substance established for control of the ecotoxic effects of the substance in an environmental medium if the value is set—
(i)
by an international scientific or regulatory body recognised by New Zealand; or
(ii)
in a convention that New Zealand has signed or ratified; or
(b)
by calculating 1 or more environmental exposure limits in accordance with this Part.
36 Ecotoxicity value
(1)
An ecotoxicity value may be set for a class 9 substance by selecting a value from the ecotoxological data available for the substance and relevant to a species that is likely to be exposed to the substance in an environmental medium that the environmental exposure limit is to be set for.
(2)
An ecotoxicity value relating to a substance deposited on an exposed surface must be modified, before being used in the formula in regulation 37, to take into account—
(a)
the frequency and duration of exposure to the substance from the particular environmental medium; and
(b)
the potential exposure routes to the substance; and
(c)
the rates of uptake of the substance through the exposure routes.
(3)
An ecotoxicity value must be expressed in the units prescribed in regulation 37(2)(a), (b), or (c).
(4)
If the available data is not expressed in the units required by subclause (3), the data must be converted to the equivalent concentration of the substance in those units.
37 Formula for calculating environmental exposure limits
(1)
An environmental exposure limit must be calculated in accordance with the following formula:
| ecotoxicity value for a substance — — — — — — — — — — — — — — Π (uncertainty factors) |
where—
- Π
is the symbol for the multiplication of a series of factors
- uncertainty factors
are the factors specified in regulations 39 to 42.
(2)
An environmental exposure limit must be expressed as follows:
(a)
for water, in milligrams of the substance per litre of water:
(b)
for soil or sediment, in milligrams of the substance per kilogram of dry weight of soil or sediment:
(c)
for a surface on which a substance may be deposited, in milligrams of the substance per square metre of surface area.
(3)
A different environmental exposure limit may be set for marine surface water and fresh surface water, and the corresponding sediments.
38 Maximum environmental exposure limits
An environmental exposure limit for a substance must not exceed—
(a)
100 milligrams of the substance per litre of water:
(b)
100 milligrams of the substance per kilogram of dry weight of soil or sediment:
(c)
1 000 milligrams of the substance per square metre of surface on which the substance is deposited.
39 Uncertainties in extrapolation of ecotoxic information from other species
(1)
A value of not less than 1 and not more than 10 must be set to allow for uncertainties due to extrapolating from data on the ecotoxic effects of the substance to another species likely to be exposed to the substance in environmental media.
(2)
A value of not less than 2 and not more than 10 must be set if the data is obtained from a study of the effects of the substance on a species that is not likely to be exposed to the substance in environmental media.
(3)
A value of 1 must be set if the data is obtained from a study of the effects of the substance on a species that is likely to be exposed to the substance in environmental media.
40 Uncertainties due to extrapolation
(1)
A value of not less than 1 and not more than 10 must be set to allow for uncertainties due to extrapolating from the data available on the ecotoxic effects of the substance to the effects on a species likely to have chronic exposure to the substance in environmental media.
(2)
A value of not less than 2 and not more than 10 must be set if the data on the ecotoxic effects after chronic exposure to the substance is not available or the data available does not adequately disclose chronic effects on the species likely to have chronic exposure to the substance in environmental media.
(3)
A value of 1 must be set if the data for ecotoxic effects after chronic exposure to the substance is available and the data adequately discloses chronic ecotoxic effects on a species likely to have chronic exposure to the substance in environmental media.
41 Uncertainties due to extrapolation of ecotoxic data to natural environment
(1)
A value of not less than 1 and not more than 10 must be set to allow for uncertainty in extrapolating from data on ecotoxic effects obtained from controlled experiments, to ecotoxic effects in environmental media.
(2)
A value of not less than 2 and not more than 10 must be set if data is unavailable to demonstrate levels at which ecotoxic effects would occur in environmental media.
(3)
A value of 1 must be set if data is available that demonstrates levels at which ecotoxic effects would occur in environmental media.
42 Uncertainties in information on biodegradation and bioaccumulation
(1)
A value of not less than 1 and not more than 10 must be set if there are uncertainties as to whether the values set under regulations 39 to 41 provide adequate protection from ecotoxic effects because the substance or an ecotoxicologically significant degradation product of the substance is likely to bioaccumulate.
(2)
A value of not less than 2 and not more than 10 must be set if the values set under regulations 39 to 41 are not likely to provide adequate protection from ecotoxic effects because the substance or degradation product of the substance is likely to bioaccumulate.
(3)
A value of 1 must be set if the values set under regulations 39 to 41 are likely to provide adequate protection from ecotoxic effects whether or not the substance or degradation product of the substance is likely to bioaccumulate.
(4)
In this regulation, degradation product means a substance created as a substance breaks down or decays in the environment.
43 Additional environmental exposure limit based on secondary poisoning
(1)
An environmental exposure limit based on secondary poisoning may be set as follows:
(a)
an ecotoxicity value in units of milligrams of the substance per kilogram of body weight per day for a species of organism that is likely to be affected by secondary poisoning must be selected:
(b)
the uncertainty factors described in regulations 39 to 42 must be applied to the ecotoxicity value selected in paragraph (a) using the formula in regulation 37 to arrive at 1 or more environmental exposure limits for secondary poisoning expressed as required by regulation 37(2):
(c)
the value arrived at under paragraph (b) must be adjusted to arrive at an environmental exposure limit for secondary poisoning, considering the circumstances of exposure, including the extent of feeding on other organisms and the amount of residue of the substance in those organisms.
(2)
If an environmental exposure limit has been set for a substance for an environmental medium based on secondary poisoning and another environmental exposure limit has been set for the same substance for the same medium based on other ecotoxicological data, the lowest environmental exposure limit is the environmental exposure limit for the substance for the medium.
(3)
In this regulation, secondary poisoning means poisoning as a result of the exposure of an organism to the substance through feeding on other organisms containing residue of the substance.
44 Application of environmental exposure limit to water
An environmental exposure limit set for a substance in surface water may not be exceeded within receiving waters after reasonable mixing.
