Application

 Subject to any licence law or other law or by-law of any province or municipality lawfully enacted with regard to storage facilities for ammonium nitrate or ammonium nitrate mixed fertilizers, the Commission, for the protection of property and the protection, safety, accommodation and comfort of the public and of the employees of the railway company and users of the railway and railway property, makes these Regulations applying to  storage facilities for ammonium nitrate and ammonium nitrate mixed fertilizers located on the right-of-way owned or leased by any railway company subject to the jurisdiction of the Canadian Transport Commission.

 These Regulations do not apply to

  • (a) storage facilities which at no time will contain more than 3,000 pounds of ammonium nitrate or ammonium nitrate mixed fertilizers;

  • (b) nitro carbo nitrates or other ammonium nitrate blasting agents; the preparation, storage or use of such blasting agents or similar mixtures in or contiguous to an ammonium nitrate or ammonium nitrate mixed fertilizer storage facility is prohibited; and

  • (c) ammonium nitrate mixed fertilizers containing less than 60 per cent ammonium nitrate by weight if they do not contain iron oxide, chromic oxide, inorganic salts of chromium, copper or manganese, powdered metals, sulphur, potassium chloride or any other ingredient in quantities which will appreciably sensitize or otherwise increase the hazard of ammonium nitrate.

PART IApplications for Approval

  •  (1) Except as provided in subsections (2) and (3), no storage facility with a capacity exceeding 200 tons, including any addition thereto, shall be constructed without an order of the Commission issued upon an application prepared and submitted in accordance with the requirements of sections 7 to 11.

PART IIDistances

 Except as provided in sections 13 and 14, the horizontal distance between a storage facility and the nearest point of another building, structure or property line, should not be less than

  • (a) 300 feet from any school, hospital, hotel, motel, church, theatre, auditorium, sports arena, multi-store shopping centre, apartment or other similar multi-unit residential building, office building or department store or merchandise building of more than one storey in height or any other similar structure used for assembly, institutional, residential, business, personal service, or mercantile purposes, or any building considered by the Commission to belong to this category;

  • (c) 100 feet from any factory, railway shop or other building used primarily for manufacturing, processing or for maintenance or repair work, or from an adjoining office building associated with these buildings, except that this distance should not be less than 50 feet if the capacity of the storage facility does not exceed 200 tons;

  • (d) 100 feet from any railway freight station, warehouse, storage tank or any other storage or transfer facility used for a combustible or dangerous commodity or from an adjoining office building associated with these buildings, except that this distance should not be less than 50 feet if the capacity of the storage facility does not exceed 200 tons;

  • (e) the following distances from the nearest point of the line of an adjoining property which has been or may be built upon and which is owned or leased by any person or company other than the owner of the storage facility:

    • (i) not less than 25 feet if the capacity of the storage facility does not exceed 200 tons,

    • (ii) not less than 50 feet if the capacity of the storage facility exceeds 200 tons, unless it is constructed of non-combustible materials as provided for by subparagraph (iii) or the adjoining property is occupied by another ammonium nitrate storage facility as provided for by subparagraph (iv),

    • (iii) not less than 25 feet if the storage facility referred to in subparagraph (ii) is of non-combustible construction and has a fire separation of not less than 1 1/2 hours on the exposed side,

    • (iv) not less than 25 feet if the property adjoining the property referred to in subparagraph (ii) is occupied by another ammonium nitrate storage facility approved in accordance with these Regulations and if there are no other buildings between the two storage facilities;

  • (f) 20 feet from the gauge side of the nearest rail of a main track or any track other than a track serving the storage facility; and

  • (g) the distances prescribed in Schedule I from the gauge side of the nearest rail of the track serving the storage facility.

 Notwithstanding section 12, greater safety distances may be imposed on storage facilities located within densely populated areas or other areas considered by the Commission to be of special hazard.

  •  (1) Notwithstanding section 12, and except as provided in subsection (2), the horizontal distance between a storage facility not exceeding a capacity of 200 tons and another on-site structure which is used only for storage purposes and which does not contain a dangerous commodity should not be less than 10 feet.

  • (2) Notwithstanding section 12 and subsection (1), lesser distances may be authorized at the discretion of the Commission between a storage facility and other on-site structures.

PART IIIDesign and Construction of Storage Facilities

 Unless specifically approved by an Order of the Commission,

  • (a) a storage facility shall not be more than one storey in height, except as may be necessary to house an elevator or similar equipment, and it shall not be erected over a basement;

  • (b) bulk storage bins shall not exceed 40 feet in height, unless they are constructed of non-combustible material.

  •  (1) It is recommended that non-combustible construction be used for storage facilities subject to these Regulations.

  • (2) If the floor or any other part of a storage facility in contact with ammonium nitrate or ammonium nitrate mixed fertilizer is fabricated from a combustible material, it shall be protected against ammonium nitrate impregnation by a plastic sheet or a suitable coating such as polyurethane or epoxy paint.

  • (3) Parts of a storage facility in contact with ammonium nitrate and fabricated from metal such as zinc, lead, copper or other metal, which will react with ammonium nitrate, shall be protected by a suitable coating.

  •  (1) Except as provided in subsections (2) to (4), the floor of a storage facility shall not contain drains, traps, pits or other depressions in which molten ammonium nitrate may become confined in the event of a fire.

  • (2) Notwithstanding subsection (1), elevator pits and conveyor trenches may be installed in the floor of a storage facility if molten ammonium nitrate is prevented from flowing into them by curbs or other construction features acceptable to the Commission, or there are extenuating circumstances that, in the opinion of the Commission, justify or minimize the hazard of an opening in the floor.

  • (3) Ammonium nitrate or mixed fertilizers containing 60 per cent or more ammonium nitrate shall not be stored in bins or piles that are contiguous to an elevator pit or conveyor trench where it is practical to store them in a location separated from the floor openings referred to in subsection (1) by bins or piles containing non-combustible and non-hazardous materials.

  • (4) Trenches shall not be constructed under railway tracks unless approval to do so has been obtained from the Commission. Applications for this approval shall be submitted through the railway company concerned.
