Municipalities
are responsible for regulating liquid waste that is discharged to the drain.
These regulations are in the form of bylaws. For a copy of the local sewer use
bylaw, contact the municipality in which your business is located.
Generally,
no flammable liquids, no corrosive liquids and no effluent that will interfere
with the operation of the sewerage control plant may be discharged into the
sewer.
Hazardous waste is
defined to include hazardous industrial waste, acutely toxic, severely toxic,
ignitable, corrosive, reactive, and leachate toxic
waste. Solid photo waste containing silver, including recovery cartridges, is
exempt. Silver-bearing liquids are considered hazardous waste. (General - Waste
Management Regulation 347, 1 – 3)
A substance is
dangerous goods when it meets the criteria for inclusion in at least one of the
9 classes of dangerous goods.
The definitions of
the nine classes of dangerous goods are as follows:
Class 1 Explosives
Substances are
included in Class 1if they are capable, by chemical reaction, of producing gas
at a temperature, pressure and speed that would damage the surroundings, or are
designed to produce an explosive or pyrotechnic effect.
Class 2 Gases
A substance is
included in Class 2 if it is a gas, an article charged with a gas, or an
aerosol.
Class 3 Flammable
Liquids
Substances are
included in Class 3 if they have a flash point less than or equal to 60.5°C.
Class 4 Flammable
Solids
Substances are
included in Class 4 if they are flammable solids, substances liable to
spontaneous combustion or substances that on contact with water emit flammable
gases (water-reactive substances).
Class 5 Oxidizing
Substances and Organic Peroxides
Substances are
included in Class 5 if they are oxidizing substances or organic peroxides.
Class 6 Toxic and
Infectious Substances
Substances are
included in Class 6 if they are liable to cause death or serious injury or to
harm human health if swallowed or inhaled or if they come into contact with
human skin, or are infectious substances.
Class 7 Radioactive
Substances
Substances with a
specific activity greater than 70 kBq/kg
are included in Class 7, Radioactive Materials.
Class 8 Corrosives
Substances are
included in Class if they are known to cause destruction of human skin, or
exhibit a corrosion rate that exceeds 6.25 mm per year at a test temperature of
55°C, as determined in accordance with the ASTM Corrosion Test.
Class 9 Miscellaneous
Products, Substances or Organisms
A substance is
included in Class 9,if
(a) it is included in Class 9 in column 3 of Schedule 1,
(b) it does not meet the criteria for inclusion in any of
Classes 1 to 8 and is intended for disposal, is in a form that can release
toxic substances through leaching (For a liquid, the UN number and shipping
name are UN3082, ENVIRONMENTALLY HAZARDOUS SUBSTANCE, LIQUID, N.O.S. For a
solid, the UN number and shipping name are UN3077, ENVIRONMENTALLY HAZARDOUS
SUBSTANCE, SOLID, N.O.S.)
(c) it does not meet the criteria for inclusion in any of
Classes 1 to 8 and is intended for disposal and is a mixture that includes an
environmentally hazardous substance listed in Appendix 5, Environmentally
Hazardous Substances Intended for Disposal (For a liquid, the UN number and
shipping name are UN3082, ENVIRONMENTALLY HAZARDOUS SUBSTANCE, LIQUID, N.O.S.
For a solid, the UN number and shipping name are UN3077, ENVIRONMENTALLY
HAZARDOUS SUBSTANCE, SOLID, N.O.S.)
(Transportation
of Dangerous Goods Regulations, Part 2)
Waste
must be packaged and marked according to the federal TDG regulations. (General
Waste Regulation 347, 19)
All containers of
waste that are dangerous goods must be labeled. The labels must be visible and
legible, and in colour where required. Each container
must display the label for the primary class of dangerous good, and a label for
the secondary class if there is one. Next to the label for the primary class
must be displayed the shipping name and the UN number of the dangerous good.
Trucks that pick up
waste that is dangerous goods must be placarded. The truck must display the
placard of the primary class of the dangerous good. (Transportation of
Dangerous Goods Regulations, Part 4)
Storage of hazardous or liquid industrial waste (subject waste) longer
than 90 days requires the generator to provide notice to the regional director
within five days after the 90th day. Subject waste must be stored
and handled to prevent leaks, spills and damage or deterioration to the storage
container. (General Waste Regulation 347, 17.2).
Generators must submit an initial generator registration and then
register annually and pay a $50 fee. Registration is done on-line. The
generator must use the generator registration number when shipping waste. (General Waste Regulation 347, 18)
Waste
can leave the work site only to a licensed hauler accompanied by a manifest.
Manifests are created on-line and a printed copy accompanies the shipment. Manifests must be kept for 2 years. (General Waste Regulation 347, 18 - 19)
All wastes that are dangerous goods must be
accompanied by a shipping document. A shipping document may be in any form,
including the waste manifest or a company-designed form, as long as it contains
all the information required by the regulation. (
The information required on a shipping
document must be easy to identify, legible, in indelible print and in English
or French.
When the information related to dangerous
goods is on the same shipping document with information related to
non-dangerous goods, the dangerous goods information must be shown in one of
the following ways:
·
before the information related to the non-dangerous goods and under the
heading "Dangerous Goods"
·
printed or highlighted in a colour that
contrasts with the print or highlight used for the information related to the
non-dangerous goods
·
by placing the letter "X" opposite the
shipping name in a column headed "DG".
The following information must be included
on a shipping document:
(a) the name and
address of the consignor
(b) the date the
shipping document was prepared
(c) the description
of each of the dangerous goods, in the following order:
(i) the shipping name
and, immediately after the shipping name unless it is already part of it, the
technical name, in parentheses, of the most dangerous substance related to the primary
class
(ii) the primary
class
(iii) the
subsidiary class or classes, in parentheses, where they exist
(iv) the UN
number
(vi) the packing
group roman numeral, which may be preceded by the letters "PG" or the words "Packing Group"
An example of the description of dangerous
goods is:
GASOLINE, 3, UN1203, PG II
(d) for each
shipping name, the quantity of dangerous goods and the unit of measure used to
express the quantity, which must be in metric units
(e) for dangerous
goods included in any of Classes 2 to 9, the number of small means of
containment (<450 litres) for each shipping name
(f) the words
"24-Hour Number", or an abbreviation of these words, followed by a
telephone number, including the area code, at which the consignor can be reached
immediately for technical information about the dangerous goods in transport,
without breaking the telephone connection made by the caller.
(g)The telephone number of a person who is
not the consignor, such as CANUTEC, but who is competent to give technical
information
(Transportation of
Dangerous Goods Regulations, Part 3)
Containers
Wastes that are
dangerous goods must be contained in UN-approved containers during handling and
transportation. At all times during the transportation, the container must meet
the requirements of the UN standard. (Transportation of Dangerous Goods
Regulations, 5.1)
Containers must be
marked to show compliance with the UN standard. The safety marks must be
visible at all times.
(Transportation of
Dangerous Goods Regulations, 5.2-5.3)
Any employee who
handles waste that is a dangerous good for the purposes of transportation,( i.e. a shipper), must be trained and have a valid
training certificate. Certificates are valid for three years. The employee need
only be trained in those parts of the regulation that pertain to his or her
job. (Transportation of Dangerous Goods Regulations, 6.1-6.2)
