For the purposes of subsection (1) above, there shall be taken to have been an emission of dark smoke from industrial or trade premises in any case where— unless the occupier or any person who caused or permitted the burning shows that no dark smoke was emitted.
material is burned on those premises, and
the circumstances are such that the burning would be likely to give rise to the emission of dark smoke,
Subsection (1) above shall not apply to the emission of dark smoke from a chimney of a building or from any other chimney to which section 1 of the principal Act (prohibiton of dark smoke from chimneys) applies.
The Minister may by regulations exempt from subsection (1) above, subject to compliance with such conditions if any as may be prescribed, the emission of dark smoke caused by the burning of any prescribed matter.
In proceedings for an offence under this section it shall be a defence to prove that the contravention complained of was inadvertent and that all practicable steps had been taken to prevent or minimise the emission of dark smoke.
In this section “industrial or trade premises” means premises used for any industrial or trade purposes or premises not so used on which matter is burnt in connection with any industrial or trade process.
The Minister may by regulations prescribe limits on the rates of emission of grit and dust from the chimneys of furnaces to which this section applies, and different limits may be prescribed under this subsection for different cases and according to different circumstances.
If on any day grit or dust is emitted from a chimney serving a furnace to which this section applies at a rate exceeding the relevant limit prescribed under subsection (1) above, the occupier of any building in which the furnace is situated shall be liable on summary conviction to a fine not exceeding level 5 on the standard scale.
In proceedings for an offence under subsection (2) above it shall be a defence to prove that the best practicable means had been used for minimising the alleged emission.
If, in the case of a building containing a furnace to which this section applies and which is served by a chimney to which there is no limit applicable under subsection (1) above, the occupier fails to use any practicable means there may be for minimising the emission of grit or dust from the chimney, he shall be liable on summary conviction to a fine not exceeding level 5 on the standard scale.
This section applies to any furnace in which solid, liquid or gaseous matter is burnt, not being a furnace designed solely or mainly for domestic purposes and used for heating a boiler with maximum heating capacity of less than 16.12 kilowatts.

to burn, at a rate of 45.4 kilograms or more an hour, any other solid matter; or
to burn, at a rate equivalent to 366.4 kilowatts or more, any liquid or gaseous matter;
The Minister may by regulations substitute for any rate mentioned in subsection (1)(b) or (c) above such other rate as he thinks fit, but no regulations shall be made under this subsection so as to reduce any such rate unless a draft of the regulations has been laid before Parliament and approved by each House of Parliament.
If on any day a furnace is used in contravention of subsection (1) above, the occupier of the building shall be liable on summary conviction to a fine not exceeding level 5 on the standard scale.
Subsection (1) above and regulations under subsection (2) above reducing any rate mentioned in subsection (1)(b) or (c) above shall not apply to a furnace which has been installed, the installation of which has been begun, or an agreement for the purchase or installation of which has been entered into, before the commencement of this section or the coming into operation of the regulations, as the case may be.
Section 6(1) of the principal Act (new furnaces to be fitted with plant to arrest grit and dust) shall not apply to a furnace to which subsection (1) above applies; and subsections (4) and (5) of that section (power of the appropriate Minister with respect to approvals under that section) shall apply in relation to an approval under subsection (1) above as they apply in relation to an approval under that section.
Where a local authority determine an application for approval under the said section 6(1) or subsection (1) above, they shall give the applicant a written notification of their decision and, in the case of a decision not to grant approval, shall state their reasons for not doing so.
The right of a person to appeal under section 6(4) of the principal Act against a decision of a local authority under that section or this section shall not be exercisable more than twenty-eight days after he is notified of the decision.
The Minister may by regulations provide that furnaces of any prescribed class shall while used for a prescribed purpose be exempted from the operation of section 3(1) above.
If on the application of the occupier of a building a local authority are satisfied that the emission of grit and dust from any chimney serving a furnace in the building will not be prejudicial to health or a nuisance if the furnace is used for a particular purpose without compliance with section 3(1) above, they may exempt the furnace from the operation of that subsection while used for that purpose.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
If a local authority to whom an application is duly made for an exemption under subsection (2) above fail to determine the application and to give a written notice of their decision to the applicant within eight weeks of receiving the application or such longer period as may be agreed in writing between the applicant and the authority, the furnace shall be treated as having been granted an exemption from the operation of section 3(1) above while used for the purpose specified in the application.
If a local authority decide not to grant an exemption under subsection (2) above, they shall give the applicant a written notification of their decision stating their reasons, and the applicant may within twenty-eight days of receiving the notification appeal against the decision to the appropriate Minister.
On an appeal under this section the appropriate Minister may confirm the decision appealed against, or may grant the exemption applied for or may vary the purpose for which the furnace to which the application relates may be used without compliance with section 3(1) above, and shall give the appellant a written notification of any decision of the Minister on an appeal under this section, stating his reasons for the decision.
If on any day a furnace which is exempt from the operation of section 3(1) above is used for a purpose other than a prescribed purpose or, as the case may be, a purpose for which the furnace may be used by virtue of subsection (2), (4) or (6) above, the occupier of the building shall be liable on summary conviction to a fine not exceeding level 5 on the standard scale.
In section 7(1) of the principal Act (measurement of grit and dust emitted from furnaces) for paragraph (b) there shall be substituted the following paragraphs :—
The Minister may by regulations substitute for any rate mentioned in the said section 7(1)(b) or (c) such other rate as he thinks fit, but no regulations shall be made under this subsection so as to reduce any such rate unless a draft of the regulations has been laid before Parliament and approved by each House of Parliament.
In the case of a furnace to which section 7(2) of the principal Act is applied and which is used— the occupier of the building in which the furnace is situate may, by notice in writing given to the local authority, request the local authority to make and record measurements of the grit, dust and fumes emitted from the furnace.
to burn, at a rate less than 1.02 tonnes an hour, solid matter other than pulverised fuel; or
to burn at a rate of less than 8.21 Megawatts, any liquid or gaseous matter;
A notice given under subsection (3) above by the occupier of a building may be withdrawn by a subsequent notice in writing given to the local authority by him or any subsequent occupier of that building.
While a notice is in force under subsection (3) above the local authority shall from time to time make and record measurements of the grit, dust and fumes emitted from the furnace to which the notice relates and the occupier shall not be under a duty to comply with any requirements of regulations under section 7(2) of the principal Act in relation to the furnace, except those imposed by virtue of paragraph (b) of that subsection.
A direction under section 7(1) of the principal Act applying section 7(2) of that Act to a furnace which is used as mentioned in subsection (3)(a) or (b) above shall contain a statement of the effect of subsections (3) to (5) above.
The occupier of a building who by virtue of the said section 7(2) is under a duty to make and record measurements of grit, dust and fumes emitted from a furnace in the building shall permit the local authority to be represented during the making and recording of those measurements.
An occupier of a building shall not knowingly cause or permit a furnace therein to which this section applies to be used in the building as mentioned in section 3(1) above as originally enacted unless the height of the chimney serving the furnace has been approved under this section and any conditions subject to which the approval was granted are complied with, and if on any day he does so, he shall be liable on summary conviction to a fine not exceeding level 5 on the standard scale.
A person having possession of a boiler or industrial plant attached to a building or for the time being fixed to or installed on any land, other than an exempted boiler or plant, shall not knowingly cause or permit a furnace thereof to which this section applies to be used as mentioned in section 3(1) above as originally enacted, unless the height of the chimney serving the furnace has been approved under this section and any conditions subject to which the approval was granted are complied with, and if on any day he does so, he shall be liable on summary conviction to a fine not exceeding level 5 on the standard scale.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
A local authority shall not approve the height of a chimney under this section unless they are satisfied that its height will be sufficient to prevent, so far as practicable, the smoke, grit, dust, gases or fumes emitted from the chimney from becoming prejudicial to health or a nuisance having regard to—
the purpose of the chimney;
the position and descriptions of buildings near it;
the levels of the neighbouring ground;
any other matters requiring consideration in the circumstances.
An approval of the height of a chimney by a local authority under this section may be granted without qualification or subject to conditions as to the rate or quality, or the rate and quality, of emissions from the chimney.
If a local authority to whom an application is duly made for approval under this section fail to determine the application and to give a written notification of their decision to the applicant within four weeks of receiving the application or such longer period as may be agreed in writing between the applicant and the authority, the approval applied for shall be deemed to have been granted without qualification.
If a local authority decide not to approve the height of a chimney under this section or to attach conditions to their approval, they shall give the applicant a written notification of their decision, stating their reasons and, in the case of a decision not to approve the height of the chimney, specifying the lowest height, if any, which they are prepared to approve unconditionally or the lowest height which they are prepared to approve if approval is granted subject to any specified conditions, or (if they think fit) both, and the applicant may within twenty-eight days of receiving the notification appeal against the decision to the appropriate Minister.
On an appeal under this section the appropriate Minister may confirm the decision appealed against, or may approve the height of the chimney without qualification or subject to conditions as to the rate or quality, or the rate and quality, of emissions from the chimney, or may cancel any conditions imposed by the local authority or substitute for any conditions so imposed any other conditions which the authority had power to impose.
The appropriate Minister shall give the appellant a written notification of any decision of the Minister on an appeal under this section, stating his reasons for the decision, and, in the case of a decision not to approve the height of a chimney, specifying the lowest height, if any, which he is prepared to approve unconditionally or the lowest height which he is prepared to approve if approval is granted subject to any specified conditions, or (if he thinks fit) both.
This section applies to the following furnaces:— . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
any furnace served by a chimney other than a chimney the construction of which was begun or the plans for which were passed before the commencement of this section;
any furnace the combustion space of which has been increased since the commencement of this section; and
any furnace the installation of which was begun after the commencement of this section and which replaces a furnace which had a smaller combustion space;
In this section “exempted boiler or plant” means a boiler or plant which is used or to be used wholly for any prescribed purpose, and references to the applicant shall, in a case where the original applicant notifies the local authority that his interest in the application has been transferred to another person, be construed as references to that other person.
