S.R. 1995 No. 60; relevant amendments are made by S.R. 1997 No. 398
1985 c. 48; relevant amendments are made by the Pesticides (Fees and Enforcement) Act 1989 (c. 27), section 1 and the Pesticides Act 1998 (c. 26) sections 1(2) to (4)
2 An “explosive” means—
(a) (i) a substance or preparation which creates the risk of an explosion by shock friction, fire or other sources of ignition (risk phrase R2);
“Risk phrase” is defined in regulation 2 of S.R. 1995 No. 60
(ii) a pyrotechnic substance is a substance (or mixture of substances) designed to produce heat, light, sound, gas or smoke or a combination of such effects through non-detonating self-sustained exothermic chemical reactions; or
(iii) an explosive or pyrotechnic substance or preparation contained in objects;
(b) a substance or preparation which creates extreme risks of explosion by shock, friction, fire or other sources of ignition (risk phrase R3).
3 “Flammable”, “highly flammable” and “extremely flammable” in categories 6, 7, 8 and 9 mean:
(a) flammable liquids—
substances and preparations having a flash point equal to or greater than 21°C and less than or equal to 55°C (risk phrase R10), supporting combustion;
(b) highly flammable liquids:
(i) substances and preparations which may become hot and finally catch fire in contact with air at ambient temperature without any input of energy (risk phrase R17),
substances which have a flash point lower than 55°C and which remain liquid under pressure, where particular processing conditions, such as high pressure or high temperature, may create major-accident hazards;
(ii) substances and preparations having a flash point lower than 21°C and which are not extremely flammable (risk phrase R11, second indent);
(c) extremely flammable gases and liquids:
(i) liquid substances and preparations which have a flash point lower than 0°C and the boiling point (or, in the case of a boiling range, the initial boiling point) of which at normal pressure is less than or equal to 35°C (risk phrase R12, first indent), and
(ii) gaseous substances and preparations which are flammable in contact with air at ambient temperature and pressure (risk phrase R12, second indent), whether or not kept in the gaseous or liquid state under pressure, excluding liquefied extremely flammable gases (including liquefied petroleum gas) and natural gas referred to in Part A; and
(iii) flammable liquid substances and preparations maintained at a temperature above their boiling point.

Notes to Parts A and B
1 Mixtures and preparations shall be treated in the same way as pure substances provided they remain within the concentration limits set according to their properties under the relevant provisions specified in CHIP, unless a percentage composition or other description is specifically given.
2 In the case of substances and preparations with properties giving rise to more than one classification the lowest thresholds shall apply.
3 Where a substance or group of substances listed in Part A also falls within a category of Part B, the controlled quantities set out in Part A must be used.
4 The addition of hazardous substances to determine the controlled quantity shall be carried out according to the following rule—
if the sum
q1/Q+q2/Q+q3/Q+q4/Q+q5/Q+...>1
(where
q x = the quantity of hazardous substance x (or category of substance) present,
Q = the relevant controlled quantity (Q) from Part A or Part B, except for those substances for which column 3 of Part A contains a quantity Q*, in which case the quantity Q* shall be used in place of the controlled quantity Q in column 2)
then the controlled quantity of each of the substances which are added together in accordance with each of paragraphs 5(a) to (c) below shall be deemed to be present for the purposes of Articles 53(1), 59(2)(a), 61(2)(a) and paragraph 4(7) of Schedule 4 (as applied by the Planning (Control of Major-Accident Hazards) Regulations (Northern Ireland) 2000) of the 1991 Order and of Article 76 (enforcement notice to have effect against subsequent development) of the 1991 Order as modified by regulation 19(1) and Part 2 Schedule 4 of the Hazardous Substances Regulations.
5 The addition rule in paragraph 4 will apply for the following circumstances:
(a) for substances and preparations appearing in Part A at quantities less than their individual controlled quantity present with substances having the same classification from Part B, and the addition of substances and preparations with the same classification from Part B;
(b) for the addition of categories 1, 2 and 10 from Part B present together;
(c) for the addition of categories 3, 4, 5, 6, 7, 8 and 9 from Part B present together.

PART C SUBSTANCES USED IN AN INDUSTRIAL CHEMICAL PROCESS
Column 1	Column 2
Hazardous substances	Controlled quantity
Where it is believed that a substance, which is within Part A or Part B, may be generated during loss of control of an industrial chemical process (“HS”), any substance which is used in that process (“S”).	The amount of S which it is believed may generate, on its own or in combination with other substances used in the relevant industrial chemical process, the controlled quantity of the HS in question.

Notes to Part C
1 The expression “which it is believed may be generated during loss of control of an industrial chemical process” has the same meaning as in the Directive.
2 Where a substance falling within Part A or B also falls within Part C, the classification with the lowest controlled quantity shall apply, subject to Note 3 to the notes to Part A and B.”

Regulation 3(9)

(This note is not part of the Regulations.)
These Regulations are concerned with the implementation of Article 12 of Council Directive 96/82/EC (O.J. No. L10, 14.1.1997, p. 13) on the control of major-accident hazards involving dangerous substances.
The main provisions of Article 12 of the Directive are the requirement to ensure that the objectives of preventing major accidents and limiting their consequences are taken into account in land-use planning policies and that these objectives are pursued through controls. There is also a requirement to ensure that planning authorities set up appropriate consultation procedures to facilitate implementation of these and other policies established under that Article.
These Regulations amend the Planning (Northern Ireland) Order 1991 (“the 1991 Order”), the Planning (Development Plans) Regulations (Northern Ireland) 1991 and the Planning (Hazardous Substances) Regulations (Northern Ireland) 1993 (“the Hazardous Substances Regulations”) and the Planning (General Development) Order (Northern Ireland) 1993.
Article 53 of the 1991 Order provides that the presence of a hazardous substance on, over or under land at or above the controlled quantity requires hazardous substances consent. The controlled quantity must be calculated by aggregating the quantity of a substance on, over or under land and certain other land or structure (together “the control zone”). Regulation 2(1) — (3) amends Article 53 by adding to the control zone any other land which forms part of a single establishment.
Regulation 2(4) amends provisions in the 1991 Order in relation to the temporary presence of hazardous substances.
Regulation 3 amends the Hazardous Substances Regulations. The main changes are amendments to the provisions for exemption from hazardous substances consent (Regulation 3(4)), the prescription of new application and claim form for hazardous substances consent (Regulation 3(7) with Schedule 1) amendment to the deemed consent conditions (Regulation 3(8)) and the prescription of a new Schedule of substances which are hazardous substances and their controlled quantities (Regulation 3(9) and Schedule 2).
Regulation 4 modifies the transitional provisions in paragraph 4 of Schedule 4 to the 1991 Order and Schedule 2 to the Hazardous Substances Regulations to make provision for deemed consent for those hazardous substances for which hazardous substances consent was not required before the commencement of these Regulations.
Regulation 5 amends the Planning (Development Plans) Regulations (Northern Ireland) 1991 to require the Department to have regard to the prevention of major-accident hazards when formulating its development plan policies.
Regulation 6 amends the Planning (General Development) Order (Northern Ireland) 1993 to require consultation with the Health and Safety Executive Northern Ireland before granting planning permission for certain categories of development.
