Schedule 1 Permitted Controlled ActivitiesI1

1. The construction, alteration or operation of the following descriptions of weir namely :

1. (a)

   a weir that is not associated with an abstraction;

2. (b)

   a weir that is not capable of being operated to control the water level upstream of the weir;

3. (c)

   a weir that is not capable of being operated so as to create a height differential between the upstream and downstream water surfaces of more than one metre.

1. (a)

   there shall be a means of demonstrating that the abstraction is less than 10 m³ in any one day;

2. (b)

   water leakage shall be kept to a minimum by ensuring all pipe work, storage tanks and other equipment associated with the abstraction and use of the water are maintained in a state of good repair;

3. (c)

   subject to paragraphs (d) and (e) the abstraction shall not cause the entry of water of a different chemical composition into any water contained in any underground strata;

4. (d)

   drilling fluids may be introduced into a well or borehole if necessary to facilitate the drilling of the well or borehole provided this does not result in pollution of the water environment;

5. (e)

   potable water may be introduced into a well or borehole to test the hydraulic properties of an aquifer;

6. (f)

   when a well or borehole is not being used for abstraction, it shall be back-filled or sealed to the extent necessary to avoid loss of any water contained in any underground strata.

1. (a)

   there shall be a means of demonstrating that the abstraction is less than 20m³ in any one day;

2. (b)

   the operator shall notify the Department of the location and volume of the abstraction —

   1. (i)

      in any case where he is carrying on that activity on the date of the coming into operation of these regulations, within 12 months of that date; and

   2. (ii)

      in all other cases, within 28 days of the date on which he commences the activity;

3. (c)

   water leakage shall be kept to a minimum by ensuring all pipe work, storage tanks and other equipment associated with the abstraction and use of the water are maintained in a state of good repair;

4. (d)

   subject to paragraphs (e) and (f) the abstraction shall not cause the entry of water of a different chemical composition into any water contained in any underground strata;

5. (e)

   drilling fluids may be introduced into a well or borehole if necessary to facilitate the boring of the well or borehole provided this does not result in pollution of the water environment;

6. (f)

   potable water may be introduced into a well or borehole to test the hydraulic properties of an aquifer;

7. (g)

   when a well or borehole is not being used for abstraction, it shall be back-filled or sealed to the extent necessary to avoid loss of any water contained in any underground strata.

4.The abstraction from a borehole where the total volume of water abstracted is less than 150 m³ in any period of one year and the purpose of the abstraction is either:

1. (a)

   subject to paragraphs (b) and (c) the abstraction shall not cause the entry of water of a different chemical composition into any water contained in any underground strata;

2. (b)

   to sample the water quality.

1. (a)

   to test the yield of the borehole or well or the hydraulic properties of an aquifer; or

2. (b)

   drilling fluids may be introduced into a well or borehole if necessary to facilitate the drilling of the well or borehole provided this does not result in pollution of the water environment;

3. (c)

   potable water may be introduced into a well or borehole to test the hydraulic properties of an aquifer;

4. (d)

   when the borehole is not being used for abstraction, it shall be back-filled or sealed to the extent necessary to avoid loss of any water contained in any underground strata.
