The compound 2,3.7.8-tetrachlorodibenzo-p-d, oxin (TCDD) was assigned a TEF of 1 after being identified by International Association of Radiology and Cancer (IARC) and World Health Organisation (WHO), as the most toxic of all compounds, and as carcinogenic to humans, based mainly on studies of cases involving accidental or occupational heavy exposure therefore the TEF is a weighting factor.g - gramµg – microgramkg - kilogram (1,000g)mg - milligrampg- microgramm₃ - cubic metreppm - Parts per milliont - tonne

PART II - Guideline on Conversion factors

(a)ppm to mg/m₃ – airThe conversion between ppm and mg/m_x3 is dependent on both the molecular weight of the substance and the temperature at which the conversion is made. The assumption is that the pollutant behaves as an ideal gas and as such, I mole of the substance occupies 22,4 litres at standard temperature (273K) and pressure (101.3 kPa). This is consistent with normalised concentrations, and it is therefore not normally necessary to take account of the temperature or pressure difference in the conversion. However, when converting ppm to mg/m³ at actual discharge conditions, it is important to take account of the necessary factors.To convert from ppm to mg/m³, the following formula should be used:mg/m³ = ppm x (MW /22.4) x (273/T) x (P/101.3)WhereMW is the molecular weight of the substance (in grams)T is the temperature at which the conversion is to be made (degrees Kelvin)P is the pressure at which the conversion is to be made (kPa)To convert from mg/m³ to ppm, the following formulae should be used:ppm = mg/m³ x (22.4/MW) x (T/273) x (101.3/P)

PART III - Factors to be considered when setting ambient air quality limits

(1)Degree of exposure of sectors of the population, and in particular sensitive subgroups.

(b)by enclosing, covering, watering, or otherwise treating loaded haul trucks and railroad cars, or limiting size of loads, to minimise loss of material to wind and spillage;

(c)by minimising the area of disturbed land or tailings;

(d)by planting special wind break vegetation at critical points;

(e)by prompt removal of coal, rock minerals, soil, and other dust-forming debris from paved roads and scraping and compaction of unpaved roads to stabilise the road surface as often as necessary to minimise re-entrainment of fugitive Particulate matter from the road surface;

(f)by minimising the period of time between initially disturbing the soil and re-vegetating or other surface;

(g)by restricting the areas to be blasted at any one time;

(h)by restricting the speed of vehicles in or around mining, tailing or quarrying operations;

(k)by using synthetic or re-vegetative covers;

(l)by restricting vehicular travel to established paved roads;

(m)by watering or chemical stabilisation of unpaved roads as often as necessary to minimise re-entrainment of fugitive Particulate matter from the road surface, or paving of roads.Where "fugitive emission" means an emission that cannot or is not reasonably likely to pass through a stack, chimney, vent or other functionally equivalent opening.

PART VII - Opacity Measurement Guidelines

The darkness of smoke is determined by comparing the shade of smoke to the shades on a Ringelmann Chart which consists of four squares with grids, which denoted shade 1 to shade 4. The darkness covered in each of these four squares represents twenty percent, fourty percent, sixty percent and eighty percent opacity respectively. Ringelmann shade 0 is completely white and shade 5 is totally black. Therefore, Ringelmann shade 1 corresponds to smoke of twenty percent opacity.The regulations stipulate that dark smoke emission from any chimney or relevant plant must not exceed:—

(i)8 minutes in any period of four hours; or

(ii)3 minutes continuously at any one time.
