Regulation 5
Column 1 Activity | Column 2 Conditions | ||
|---|---|---|---|
1. The construction, alteration or operation of the following descriptions of weir namely : (a) a weir that is not associated with an abstraction; (b) a weir that is not capable of being operated to control the water level upstream of the weir; (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. | |||
| 2. The abstraction of less than 10 m3 of water in any one day. | (a) there shall be a means of demonstrating that the abstraction is less than 10 m3 in any one day; (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; (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; (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; (e) potable water may be introduced into a well or borehole to test the hydraulic properties of an aquifer; (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. | ||
| 3. The abstraction of between 10m3 and 20m3 of water in any one day. | (a) there shall be a means of demonstrating that the abstraction is less than 20m3 in any one day; (b) the operator shall notify the Department of the location and volume of the abstraction — (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 (ii) in all other cases, within 28 days of the date on which he commences the activity; (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; (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; (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; (f) potable water may be introduced into a well or borehole to test the hydraulic properties of an aquifer; (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: (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; (b) to sample the water quality. | (a) to test the yield of the borehole or well or the hydraulic properties of an aquifer; or (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; (c) potable water may be introduced into a well or borehole to test the hydraulic properties of an aquifer; (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. | ||
