CLEAN WATERS REGULATIONS 1972 - REG 2 Definitions 2 Definitions (1) In these Regulations, except in so far as the context or subject- matter otherwise indicates or requires: "biochemical oxygen demand" means the quantity of oxygen utilised in the biochemical oxidation of organic matter in a sample of waters or of wastes, determined in accordance with the method specified in the Approved Methods Publication. "chemical oxygen demand" means the quantity of oxygen utilised to oxidise matter determined in accordance with the method specified in the Approved Methods Publication. "common drain" means any drain, other than a sewer, which is vested in, or is in the care, control or management of, or is on land occupied by, a person and which is or is likely to be used for the conveyance of any pollutant into waters from any other drain which is vested in, or is in the care, control or management of, or is on land occupied by, some other person. "dangerous goods" has the same meaning as in the Road and Rail Transport (Dangerous Goods) Act 1997. "overflow drain" means any drain which is used or is likely to be used to divert any pollutant into any waters from another drain when that other drain is surcharged as a result of damage, excessive rainfall or any emergency. "restricted substance" means any substance specified in column 1 of Schedule 2. "the Act" means the Clean Waters Act 1970. "the Approved Methods Publication" means the document entitled “Approved Methods for the Sampling and Analysis of Water Pollutants in New South Wales” prepared by the EPA and published in the Gazette, as in force from time to time. "thermal wastes" means any liquid which, after being used in or in connection with any manufacturing, trade or domestic process, is discharged into waters and which, immediately before it is so discharged, has a temperature of 2 degrees Celsius or more greater than the temperature, taken immediately before or immediately after the temperature of the liquid being discharged is taken, of any similar liquid immediately before it is used in or in connection with that manufacturing, trade or domestic process. (3) Where in these Regulations a reference is made to any act, matter or thing as being an “approved” act, matter or thing, that reference is to any such act, matter or thing, as the case may be, as the Commission may from time to time approve. CLEAN WATERS REGULATIONS 1972 - REG 3 Testing of water and wastes 3 Testing of water and wastes (1) Where for the purposes of these Regulations any test for determining the nature or concentration in waters or in wastes of any matter is carried out, that test shall be carried out in accordance with the appropriate method specified in the Approved Methods Publication. (2) Notwithstanding clause (1), the person carrying out any test pursuant to that clause, may, where the result of the test would not be affected, vary the procedural details specified in the method utilised. (3) For the purposes of Regulation 8, the nature or concentration in waters or wastes of any matter is to be determined in accordance with any applicable condition of a licence that specifies the procedures or methods to be used by the licence holder concerned, or if there is no applicable condition, in accordance with any procedures or methods determined in writing for that purpose by the Authority. (4) Without limiting clause (3), the procedures or methods that may be specified include the use of sampling procedures or methods of statistical analysis. (5) In the event of any inconsistency between the requirements of clauses (1) and (3), the requirements of clause (3) prevail to the extent of that inconsistency. (6) The Authority is to make available to any person on request a copy of any determination made under clause (3).
