HISTORY The United States EPA has
conducted studies to determine to what extent installation errors lead to
underground storage tank leaks. Their findings in a 1986 study showed
46% of tank and piping failures were either the fault of poor design or
construction installation mistakes. An example of poor design is insufficient
ground cover over a product line. An installation mistake may have
been the use of wood blocking left under buried piping in a trench.
This information led to many jurisdictions in North America implementing
training courses and certification programs for installers. Training
included safety for the personnel performing the work, especially when working
with tanks that have contained gasoline and are capable of explosion.
In the Spring of 1992, Alberta MUST sponsored a
one (1) day training program for tank installers and removers. This
program was conducted in response to pending changes to the Alberta Fire Code
which would make it mandatory for installers/removers to be "approved".
The installation course gave contractors a look at current industry standards
and concentrated on the installation requirements dictated by the major fuel
tank and piping manufacturers. The removal course emphasized the
importance of purging, inerting and doing periodic monitoring of the tank
atmosphere.
When the approval requirement came into effect on
August 31, 1992, all individuals who successfully completed this program,
and proved experience were granted temporary approval for installing and
removing tanks and piping systems. Since then, any individuals
seeking certification were granted licenses based on successful completion of an
examination, and providing proof of applicable experience.
Reaction to the 1992 training program by attendees
was mixed. Prevailing opinions concurred that a training program
tailored more to Canada, and in particular Alberta, would be more
appropriate. It was also felt that course content should include more
topics, and deal with topics in more depth, and with hands-on training.
These events inspired Alberta contractors to
become more involved in what was happening in their industry, and have a say in
the changes that were being proposed. Thus A.P.S.S.C.A. was organized by
concerned contractors. |
