Division 32Production of sodium carbonate (soda ash) and sodium bicarbonate

### Division 32—Production of sodium carbonate (soda ash) and sodium bicarbonate 332 (1) The production of sodium carbonate (soda ash) and sodium bicarbonate is the chemical and physical transformation of calcium carbonate (CaCO3), sodium chloride (salt (NaCl)), ammonia (NH3) and carbon bearing materials (such as coke) into one or more of the following: (a) light sodium carbonate (light soda ash (Na2CO3)) which has a concentration of sodium carbonate (soda ash (Na2CO3)) of at least 98.0%; (b) dense sodium carbonate (dense soda ash (Na2CO3)) which has a concentration of sodium carbonate (soda ash (Na2CO3)) of at least 97.5%; (c) refined sodium bicarbonate (NaHCO3) which has a concentration of sodium bicarbonate (NaHCO3) of at least 95.0%. (2) The production of sodium carbonate (soda ash) and sodium bicarbonate is specified as an emissions‑intensive trade‑exposed activity. (3) The production of sodium carbonate (soda ash) and sodium bicarbonate is a highly emissions‑intensive activity. > Note: See Part 4. (4) The basis for the issue of free carbon units for the production of sodium carbonate (soda ash) and sodium bicarbonate is by a tonne of one or more of the following: (a) light sodium carbonate (light soda ash (Na2CO3)) that: (i) has a concentration of sodium carbonate (soda ash (Na2CO3)) of at least 98.0%; and (ii) is produced by carrying on the emissions‑intensive trade‑exposed activity; and (iii) is of saleable quality; (b) dense sodium carbonate (dense soda ash (Na2CO3)) that: (i) has a concentration of sodium carbonate (soda ash (Na2CO3)) of at least 97.5%; and (ii) is produced by carrying on the emissions‑intensive trade‑exposed activity; and (iii) is of saleable quality; (c) refined sodium bicarbonate (NaHCO3) that: (i) has a concentration of sodium bicarbonate (NaHCO3) of at least 95.0%; and (ii) is produced by carrying on the emissions‑intensive trade‑exposed activity; and (iii) is of saleable quality. > Note: Saleable quality is explained in Part 2.
