Section 3.1 Cement and lime manufacture and associated processes

Part A

(a) Making cement clinker.

(b) The heating of calcium carbonate or calcium magnesium carbonate for the purpose of making lime where the process is likely to involve the heating in any 12 month period of 5000 tonnes or more of either substance, or in aggregate of both.

(c) Grinding cement clinker, if related to a process described in paragraph (a).

(d) Any of the following processes, where the process is related to a process described in paragraph (a), namely, blending cement, putting cement into silos for bulk storage and removing cement from silos in which it has been stored in bulk and any process involving the use of cement in bulk, including the bagging of cement and cement mixtures, the batching of ready-mixed concrete and the manufacture of concrete blocks and other cement products.

(e) The slaking of lime for the purpose of making calcium hydroxide or calcium magnesium hydroxide when the process is related to a process described in paragraph (b).

Part B

(a) Grinding cement clinker, if not related to a process described in Part A.

(b) The heating of calcium carbonate or calcium magnesium carbonate for the purpose of making lime where the process is not likely to involve the heating in any 12 month period of 5000 tonnes or more of either substance or in aggregate of both.

(c) The slaking of lime for the purpose of making calcium hydroxide or calcium magnesium hydroxide when the process is related to a process described in paragraph (b) above.

(d) Any of the following processes, other than at a construction site, namely, blending cement, putting cement into silos for bulk storage and removing cement from silos in which it has been stored in bulk and any process involving the use of cement in bulk, including the bagging of cement and cement mixtures, the batching of ready-mixed concrete and the manufacture of concrete blocks and other cement products where the process is not related to a process described in paragraph (a) of Part A of this section and is carried on at the same location as a process described in Part B of Section 3.4.

Part C

Any of the following processes, if not related to a process falling within a description in Part A or B of this Section:

(a) storing, loading or unloading cement or cement clinker in bulk prior to further transportation in bulk;

(b) blending cement in bulk or using cement in bulk other than at a construction site, including the bagging of cement and cement mixtures, the batching of ready-mixed concrete and the manufacture of concrete blocks and other cement products;

(c) the slaking of lime for the purpose of making calcium hydroxide or calcium magnesium hydroxide unless related to and carried on as part of a process falling within another description in this Schedule.
