Dark smoke 2.—

(1)

For the purposes of section 11 of the Act, dark smoke includes smoke of any colour which appears to the Director-General or any authorised officer —

(a)

to be darker than shade No. 1 on the Ringelmann Chart;

(b)

when observed or recorded with such instrument or device as the Director-General may approve, to be darker than shade

No. 1 on the Ringelmann Chart; or

(c)

(2)

Section 11 of the Act shall not apply to the emission of dark smoke from any chimney where —

(a)

the emission of dark smoke is for a duration of less than 5

minutes in any period of one hour in a day; and

(b)

the total number of emissions of dark smoke from that chimney does not exceed 3 times a day.

Methods of smoke indication 3.—

(1)

Every occupier of any industrial or trade premises in or on which any industrial plant or fuel burning equipment is situated shall, if required by the Director-General to do so, provide or install such instrument, equipment or device in or on the premises in accordance with paragraphs (2) and (3).

(2)

The instrument, equipment or device referred to in paragraph (1)

must be of such type and installed in such manner as will enable any person in charge of the industrial plant or fuel burning equipment to readily ascertain at all times and without leaving the boiler room, furnace room or control room, whether smoke is being discharged from any chimney on the industrial or trade premises.

(3)

The instrument, equipment or device may include one or more of the following:

(a)

a smoke density indicator, recorder and alarm which will provide adequate indication in the boiler room, furnace room or control room of the density of smoke being discharged from the chimney;

(b)

a closed circuit television installation with the receiver located in the boiler room, furnace room or control room; or

(c)

any other instrument, equipment or device approved by the

Director-General.

Standards of concentration of air impurities 4.—

(1)

For the purposes of section 12 of the Act, the standards of concentration of air impurities that must be complied with in the conduct of any trade, industry or process or the operation of any fuel

Testing procedures and requirements 5.—

(1)

For the purposes of section 12 of the Act, the Director-General may specify in any particular case, the point at which the concentration of air impurities shall be measured.

(2)

The point at which the concentration of air impurities shall be measured may be situated at —

(a)

the fixed point of emission of any air impurities;

(b)

the final point of emission of any air impurities; or

(c)

any other point in or along any flue, duct or chimney located at a place in the premises other than the final point of emission of air impurities.

(3)

Every owner or occupier of any industrial or trade premises shall —

(a)

carry out such tests with respect to the emission of air impurities from and the consumption of fuel in or on the premises as may be required by the Director-General;

(b)

keep a register of all such tests, specifying the date, nature and results of each test; and

(c)

ensure that such register is available for inspection by the

Director-General or any authorised officer at all reasonable times.

(4)

The results of a test conducted with respect to the emission of air impurities for the following equipment must be expressed on the basis of flue gas containing the corresponding percentage of oxygen by volume:

(a)

boilers burning gaseous and liquid fuels — 3%;

(b)

boilers burning solid fuels — 6%;
