(b)in no case is black smoke emitted for more than 3 minutes in total in any period of 30 minutes.

(2) In paragraph (1)(b), "black smoke" means smoke which, if compared in the appropriate manner with a chart of the type known on 5th July 1956 (the date of the passing of the Clean Air Act 1956(3)) as the Ringelmann Chart(4), would appear to be as dark as or darker than shade 4 on the chart.

(3) For the purposes of Schedule 1, a vessel is not under way when it is at anchor or made fast to the shore or bottom, and a vessel which is aground is deemed to be under way.

PART 2Arrestment plant - exemptions

Arrestment plant exemptions

4.  A class of furnace listed in column 1 of Schedule 2 to these Regulations, while used for a purpose set out in column 2 in relation to that class, is exempted from the provisions of section 6(1) (which requires the fitting of arrestment plant to new non-domestic furnaces).

PART 3Height of furnace chimneys - exemptions

Exempted boilers or plant

5.  (1)  The purposes set out in paragraph (2) are prescribed purposes in relation to section 14(7) (section 14 relates to the height of chimneys serving furnaces connected with boilers or industrial plant, but exempts from certain of its provisions any chimney serving the furnace of a boiler or plant used or to be used wholly for a prescribed purpose).

(2) The purposes are-

(a)temporarily replacing any other boiler or plant which is-

(i)under inspection, maintenance or repair;

(ii)being rebuilt; or

(iii)being replaced by a permanent boiler or plant;

(b)providing a temporary source of heat or power during any building operation or work of engineering construction (within the meaning of section 176(1) of the Factories Act 1961(5));

(c)providing a temporary source of heat or power for investigation or research;

(d)providing products of combustion to heat other plant (whether directly or indirectly) to an operating temperature;

PART 4Information about air pollution

Section 36 notices concerning emissions from chimneys and other outlets

6.  A section 36 notice may relate to the emission of pollutants and other substances from any chimney, flue or other outlet used for the discharge, from any premises to the atmosphere, of any emission of any of the following kinds-

(a)sulphur dioxide or particulate matter derived from any combustion process where the material being heated does not contribute to the emission;

(b)any gas or particulate matter derived from any combustion process where the material being heated contributes to the emission;

(c)any gas or particulate matter derived from any non-combustion process or other similar industrial activity.

Information which may be required by a section 36 notice

7.  (1)  Subject to paragraph (2), a section 36 notice must specify the premises to which it relates and may require the provision of estimates or other information, in respect of those premises, of any of the following kinds-

(a)in relation to emissions of sulphur dioxide during any specified period-

(i)the total duration of all discharges from the specified premises during that period;

(ii)(aa)the temperature in degrees Celsius,

(bb)the efflux velocity in metres per second, and

(cc)the volume flow rates in cubic metres per hour,

of the gases discharged from any specified chimney or flue or other specified outlet during that period, and the height in metres above ground level at which each such discharge takes place;

(iii)the total quantity of sulphur dioxide discharged during that period, to be ascertained, in the case of sulphur dioxide derived from a combustion process, either by calculation from the quantity of fuel or other matter burnt and its sulphur content, or, if the occupier of the premises and the local authority so agree, by direct measurement;

(b)in relation to total emissions of particulate matter of all kinds during any specified period-

EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations consolidate six sets of regulations concerning clean air, made under enabling powers which were repealed and re-enacted as part of the Clean Air Act 1993 (c. 11) ("the Act").

Section 1 of the Act, as applied by section 44 of that Act, makes it an offence to emit dark smoke (as defined) from the chimney of a vessel, but under subsection (3) of that section the Secretary of State may prescribe in regulations that section 1 does not apply to emissions of smoke lasting for not longer than such periods as may be prescribed. Regulation 2 and Schedule 1 contain the prescribed classes of emissions and permitted periods of time.

The Ringelmann Chart mentioned in regulation 2(2) is derived from BS 2742M. Documents can be obtained from the British Standards Institution online at www.bsigroup.com, or hard copies can be obtained from the British Standards Institution customer services at 389 Chiswick High Road, London, W4 4AL upon payment of a fee.

Section 6(1) of the Act requires that new non-domestic furnaces must be provided with plant approved by the local authority for arresting grit and dust. Section 7(1) permits the Secretary of State by regulations to provide that furnaces of any class prescribed in the regulations, while used for a prescribed purpose, be exempted from the effect of section 6(1). Regulation 3 and Schedule 2 contain the prescribed classes of furnace and purposes.

Section 14(2) of the Act requires that a furnace in a building must not be used for certain purposes unless the height of the chimney serving the furnace has been approved by the local authority or the Secretary of State under section 15 of the Act, and any conditions to which the approval was subject have been complied with. However, if a boiler or plant is used or is to be used wholly for a purpose prescribed by the Secretary of State under section 14(7), it is an exempted boiler or plant and approval for the height of the chimney need not be obtained. Regulation 4 contains the prescribed purposes, which include temporary or local provision of heat or power during replacement or maintenance, building operations, engineering construction, investigation or research, and agricultural operations.

Section 36 of the Act empowers a local authority by notice to require the occupier of any premises (but not private dwellings) to provide information concerning the emission of pollutants and other substances into the air from the premises. Regulation 5 prescribes the kinds of emissions to which notices under section 36 may relate, regulation 6 prescribes the kinds of information which may be required by those notices, and regulation 7 prescribes the manner in which such notices are to be sent by post and the evidence which is to be sufficient evidence that such a notice has been given (see section 38(1), (3)(a) to (c) and (4) of the Act).

Any person who has an interest in the premises may appeal against such a notice to the Secretary of State under section 37 of the Act. Regulation 8(1) to (3) prescribes the manner in which an appeal under section 37 is to be made, and the time within which it may be brought. Regulation 8(4) to (6) specifies the circumstances in which the Secretary of State is required to withhold certain parts of the appellant's case from the respondent local authority, and the documents which the Secretary of State is otherwise required to send to the authority. Regulation 8(7) to (9) prescribes the procedure to be followed before the Secretary of State determines an appeal.

Regulation 9 requires each local authority to maintain a register containing information concerning emissions from premises which has been obtained by the authority under section 35 of the Act (other than information which, by direction of the Secretary of State, is not be to disclosed) and information concerning certain appeals against section 36 notices (see section 38(1) and (3)(d) of the Act).

Section 36(6) of the Act empowers the Secretary of State to prescribe in regulations certain premises used in the public service of the Crown to which section 36 is not to apply. Regulation 10 and Schedule 3 contain the Crown premises that are prescribed.
