Environmental Code of Practice for Aboveground and ... - CCME

Appendix B Explanatory Material
B.1.4.2 Allied petroleum product - It is understood
that a number of chemicals not included in
this definition may be stored in underground
storage tanks. This definition, however,
represents combustible and flammable
products that are directly petroleum-based
and are the most widely used petroleum
products in the manufacturing sector.
B.1.4.2 Interstitial space includes the following
space:
(a) outside the storage tank bottom and
above a synthetic membrane liner or
prepared soil layer;
(b) between the storage tank bottom and a
secondary bottom creating a leakcontainment
space;
(c) between two pipes of a double-wall
piping system;
(d) between a pipe and a synthetic
membrane liner; or
(e) space between a storage tank and a
secondary containment system.
B.1.4.2 Used oil - The definition of used oil was
taken from the 1989 CCME publication, PN
1042, “Code of Practice for Used Oil
Management in Canada” with the following
modifications.
(a) the category of “metal-working fluids”
has been removed as this product class is
considered to be sufficiently different
from the definition of petroleum
products. Since metal-working fluids
may include a substantial amount of
water, further consideration would have
to be given to the need to line steel tanks.
(b)the category of “insulating fluids or
coolant” has been modified for similar
reasons, and now reads as “insulating oils”.
Used oil contains primarily hydrocarbons;
however, it may also contain additives (e.g.,
a total of 14% by volume of detergents and
viscosity-improvers in lubricating oils for
gasoline engines). It contains physical and
chemical impurities (e.g., solids, metals, and
chlorinated organics) due to physical
contamination and chemical reactions
occurring during its use. Contamination of
used oil may also occur from mixing with
other oily fluids or fluid wastes when it is
collected for recycling.
This Code does not treat used oil exclusively
as a hazardous waste. Used oil may or may
not be designated as a hazardous waste
depending on the types and amounts of
chemical impurities it contains. For
example, used oil containing 50 ppm or
more of PCBs is designated as a hazardous
waste in most Canadian jurisdictions. If the
used oil is designated as a hazardous waste,
other requirements for its storage may apply.
Consult the authority having jurisdiction.
B.3.2.6 The CCME “Guideline for Controlling
Emissions of Volatile Organic Compounds
from Aboveground Storage Tanks” applies
to storage tanks having a capacity of more
than 4 000 L, designed to contain a
petroleum product that has a vapour pressure
of 10 kPa or greater. The published
document is available from Manitoba
Statutory Publications.
B.3.3.1(1)
(e)(ii) The overfill alarm system required shall be
in addition to the alarm or gauging system
that is routinely used. This system shall be
used as a back-up system when the primary
means of detecting a high level has failed.
B.3.5.1
(2) It is important to note that the requirements
of the fire authorities must be met if any
used oil collection tank is considered for
use indoors.
