Regulation 3
1. The sludge producer shall ensure that agricultural soil is tested or assessed in accordance with this Schedule.E+W+S
Commencement Information
I1Sch. 2 para. 1 in force at 1.9.1989, see reg. 1(1)
2.—(1) Where–E+W+S
(a)sludge has been used on an agricultural unit before the operative date; and
(b)adequate scientific evidence is available as to the characteristics of the soil thereof, and the sludge used thereon, before that date;
an assessment shall be made as soon as possible after the operative date of the pH value of the soil as at that date, and the probable concentrations in the soil as at that date of–
(i)chromium;
(ii)the elements listed in column 1 of the soil table;
and the soil shall be tested not later than 31st December 1991.
(2) Subject to paragraph (1) above, the soil of agricultural land shall be tested–
(a)where sludge is to be used on that land for the first time after the operative date;
(b)as soon as may be after the twentieth anniversary of the date when the soil was last tested in accordance with this Schedule; or
(c)where the sludge producer is so requested in writing by the occupier of the land or by [F1the Environment Agency] [F2or, in Scotland, the Scottish Environment Protection Agency] [F3or, in Wales, the Natural Resources Body for Wales], and not less than five years have elapsed since the soil was last tested in accordance with this Schedule.
