The Contractor will submit to the Authority a test-mining plan sufficiently in advance.
Those mentioned in section 7.2.3.6 to7.2.3.7 are highly recommended for measurement during the test-mining period.
It would only be at the test-mining stage that significant potential effects could occur.
Its species composition should be comparable to that of the test-mining area.
For each test-mining by-product, the timescale over which it causes significant environmental impact must be modelled.
The zone should have species composition comparable to that of the test-mining area.
The preservation reference zone should be located upstream of test-mining operations. The preservation reference zone should be outside the test-mining area and areas influenced by the plume.
The zone should have species composition comparable to that of the test-mining area.
With the currently proposed exploration and test-mining techniques, the primary anticipated test-mining by-products are particles created by the mechanical break-up of the mined minerals.
The time scales for the environmental impact of each test-mining by-product must be modelled.
Because oxygen-minimum zones vary in size regionally and to some extent seasonally,environmental studies should determine the depth range of the oxygen-minimum layer in each test-mining area.
The preservation reference zone should be outside the test-mining area and areas influenced by the plume.
In addition, the parameters mentioned in section7.2.3.1 to 7.2.3.5 should be measured during the test-mining period.
Areas representative of the test-mining site, but in which no test mining shall occur; used to assess changes in the biological status of the environment caused by test-mining activities.
Further transects shouldbe carried out in crust areas of potential test-mining interest;
This should be done at least four times before test-mining operations begin(to measure natural variability) and thereafter at least annually to monitor possible changes due to test-mining activity.
The monitoring programme proposed by the contractormust provide details of how the impacts of the test-mining activities will be assessed.
Baseline data documenting natural conditions prior to test mining are essential in order tomonitor changes resulting from test-mining impacts and to predict impacts of commercial mining activities.
Knowledge of the dispersal potential is also required for monitoring andmitigating the effects of accidental spills relating to the test-mining operations.
This should be replicated over time before test-mining operations begin(to measure natural variability) and thereafter at least annually to monitor possible changes resulting from test-mining activity.
For environmental assessments, this test phase should be monitored intensively,as should tests of any test-mining component.
The programme will also authorize refinement of the test-mining plan prior to testing and at other appropriate times, if refinement is necessary to reflect proposed operations accurately or to incorporate recent research or monitoring results.
The third baseline data group(sediment properties, including pore water chemistry)is targeted at predicting the behaviour of the discharge plume and the effect of test-mining activity on sediment composition.
High-resolution, high-quality bathymetric data shouldbe collected over the area where the dispersal of test-mining by-products is expected to significantly affect the environment(i.e. over the entire region covered by the numerical circulation model).
The dispersal potential near possible mining sites should be assessed even ifthe design target of the mining technology includes avoidance of the release of any test-mining by-products into the environment.
In regions of geomorphologic relief near the test-mining site, horizontal and vertical resolutions should be increased to allow dynamical structures associated with deep-sea topography(e.g. boundary currents, trapped eddies, overflows) to be resolved.
To set up the environmental baseline in the exploration area as required under the relevant Regulations, the contractor, utilizing the best available technology, including the Geographical Information System, and using robust statistical design in preparing the sampling strategy, shall collect data for the purpose of establishing baseline conditions of physical, chemical, biological and other parameters that characterize the systems likely tobe impacted by exploration and possible test-mining activities.
In regions of geomorphological relief near the test-mining site, horizontal and vertical resolutions should be increased to allow dynamical structures associated with deep-sea geomorphology(e.g. boundary currents, trapped eddies, overflows) to be resolved.
Before large volumes ofdeep water are brought to the surface in a test-mining activity, an environmental impact assessment is required, because environmental changes may alter food chains, disturb vertical and other migrations and lead to changes in the geochemistry of an oxygen-minimum zone, if present.
