REGULATORY IMPACT ANALYSIS STATEMENT

(This statement is not part of the Regulations.)

Issue and objectives

The Transportation of Dangerous Goods Act, 1992 (TDG Act, 1992) and the Transportation of Dangerous Goods Regulations (TDG Regulations) are intended to promote public safety in the transportation of dangerous goods in Canada.

The proposed Regulations Amending the Transportation of Dangerous Goods Regulations (Amendment 9) would update the references in section 1.3.1, Table of Safety Standards and Safety Requirement Documents, to two safety standards published by the Canadian General Standards Board (CGSB), CGSB-43.126 on drums, and CGSB-43.147 on rail transport, would make consequential amendments to sections 5.9 and 5.12 of Part 5, Means of Containment and would remove a sunset date from special provision 89 in Schedule 2 referring to subsection 5.12(1). This proposed regulatory change also updates the references to the International Civil Aviation Organization (ICAO) Technical Instructions and the Supplement to the ICAO Technical Instructions to the 2009-2010 Edition. The 2009-2010 Edition is now available in English and French and the update is a timely addition to this amendment.

CGSB-43.126 was changed in September 2008 and harmonises the TDG Regulations with the requirements in the United Nations (UN) Recommendations on the Transport of Dangerous Goods Model Regulations for drums, notably the leakproofness test. CGSB-43.147 was amended in July 2008. Among other things, it clarifies the inspection and testing requirements applicable to means of containment for the handling, offering for transport or transporting of dangerous goods by rail.

Description and rationale

The proposed changes relative to the September 2008 version of CGSB-43.126 are made to harmonise with the United Nations’ requirements for drums used in the transport of dangerous goods. CGSB-43.126 covers steel and plastic drums. The implications of this new standard in Canada are

- for steel drums:

  • a minor change in the required thickness of the body of a drum for reconditioning (top/body/bottom greater than or equal to 1.0/0.8/1.0 mm from 1.0/1.0/1.0 mm or 1.1/0.8/1.1 mm used previously) reflecting the thickness of used drums currently available on the market and that have proven to be amenable to reconditioning for dangerous goods;
  • a change in pressure requirements for leak tests from 50 kPa to 30 kPa or 20 kPa depending on the packing group, with a leak test of five (5) minutes instead of three (3) seconds.

- for plastic drums:

  • a minimum thickness requirement of 2.2 mm for reconditioning;
  • a change in pressure required for leak tests from 25 kPa to 30 kPa or 20 kPa depending on the packing group, with a leak test of five (5) minutes instead of three (3) seconds;
  • a permitted use period for a plastic drum of sixty (60) months from the date of manufacture without exception.

Although the thickness requirements for steel drums in the September 2008 version of CGSB-43.126 are lower (top/body/bottom of 1.0/1.0/1.0 mm or 1.1/0.8/1.1 mm were previously used), there is minimal anticipated saving, because the same drums will be used and the purchase of new drums will only be marginally less expensive. Some companies already use drums with lower steel thicknesses and some of these drums will become available for reconditioning. The lower thickness requirement was chosen by consensus at the standard committee level based on the experience and safety record of reconditioners with these drums in other countries.

The change in the September 2008 version of CGSB-43.126 to the requirements for leakproofness tests introduces some lower pressure requirements but extends the length of the test (from three (3) seconds to five (5) minutes), aligning the test with the UN Recommendations. The new leakproofness test is equivalent in terms of safety. The benefits of lower pressure levels are that the top and bottom of steel drums will no longer bulge under pressure, a problem that necessitated a restraint or push back of the drum, reducing the efficiency of the test. Most reconditioners use an equivalent (validated and documented) test method as allowed under the standard.

The permitted use period and the reconditioning requirements represent the largest difference for the users of plastic drums. The previous standard allowed new plastic drums dedicated to transporting single dangerous goods included in Packing Group II or III to be used for up to ten years without reconditioning “provided that the filler has documented and demonstrated that the drum or jerrican continues to meet performance requirements”. The packing group indicates the level of hazard of dangerous goods: Packing Group I indicates great danger, Packing Group II indicates medium danger and Packing Group III indicates minor danger. In the September 2008 version of CGSB-43.126, all plastic drums will have a permitted use period of five (5) years and will be subject to reconditioning.

The costs foreseen are for the increase in reconditioning of plastic drums or, alternatively, their disposal and replacement. Consultation indicates that companies previously using dedicated plastic drums have switched to regular reconditioning and, therefore, would not be affected.

The revised standard on rail, CGSB-43.147, introduces a number of changes, the most significant are the following listed by subject:

- safety requirements and accident prevention measures

  • modify welded attachment requirements on tank car tanks – this change was derived from accident cause analysis,
  • add requirements for the qualification of tank cars used for cryogenic liquids,
  • clarify that the joint between tank car service equipment and unloading equipment must be adequate to prevent leakage,
  • clarify the need to disconnect loading and unloading hoses when the loading or unloading is discontinued,
  • establish the acceptable level of defects in tank car thermal protection systems based on results from Transport Canada’s research projects,
  • clarify the tank container impact test administrative provisions and update the technical requirements to align with International Standard ISO 1496-3, Amendment 1;

- permits for equivalent level of safety

  • allow tank cars (excluding tank cars for dangerous goods included in Class 2) to have a gross weight of up to 286 000 lbs (previously covered by permit),
  • grandfather tank cars previously built and operated under permit;

- miscellaneous

  • exempt from the inspection of hydrogen peroxide ceramic venting devices for tank cars being returned after unloading,
  • remove the adoption by reference of the commodity name marking requirements in 49 CFR, Part 172.330 (the United States’ regulations).

These changes should have a positive impact on safety as the criteria for testing and inspection improve with better knowledge and understanding. There might be some savings in administrative cost since some permits for equivalent level of safety will no longer be required. For example, a number of permits have been issued with strict conditions to allow an increased gross weight of tank cars up to 286 000 lbs and have been effective; therefore these permits have been incorporated into the standard.

The addition of section 5.9 is intended to quantify the limits and the extent beyond which some defects to tanks would be considered a danger to public safety if tank cars were to be transported with those defects present. Currently, there are no regulatory quantifiable limits for defects in the tanks such as dents and buckles. With this proposal a tank car cannot be used for the transportation of dangerous goods if the tank shell has a deformation greater than 19 mm (0.75 inch) or 0.75% of the inside diameter, whichever is lowest.

Section 5.9.1 indicates that the application for registration of a tank car facility no longer requires evidence of a valid and current certification with the Association of American Railroads. This requirement was previously implemented as a practical transition measure to minimise the administrative burden when Transport Canada started to register these facilities. This is no longer necessary.

The proposed changes include a modification to special provision 89 in Schedule 2 of the TDG Regulations removing the cut-off date of January 1, 2010, for using the means of containment described in the special provision. This special provision will ultimately be placed in a technical standard and there is no reason to maintain the cut-off date.

The proposed amendments would not impact the intent or the scope of the TDG Regulations. They are expected to enhance the administration of the transportation of dangerous goods regulatory program, increase safety and maintain alignment with international standards. It is anticipated that the proposed amendments would have a minimal but positive impact on the way consignors and carriers of dangerous goods do business.

In accordance with the Cabinet Directive on the Environmental Assessment of Policy, Plan and Program Proposals, and the Transport Canada Policy Statement on Strategic Environmental Assessment, a strategic environmental assessment (SEA) of the amendments was conducted, in the form of a Preliminary Scan. The SEA concluded that the amendments are not likely to have important environmental implications.

Consultation

Consultation included the identification of issues and concerns, and a major effort to obtain a wide consensus, involving standard committees, groups and organizations responsible for public safety. Costs and benefits, alternatives, enforcement policies and public safety initiatives were raised and discussed. Informal consultation was initiated in the fall of 2008 with stakeholders i.e., manufacturers and users of drums and the rail industry and comments are favourable. The comments provided by the stakeholders assisted in understanding the impact of the changes.

For the standard on drums, CGSB-43.126, there was very little reaction to the additional reconditioning requirements for plastic drums. Those who commented indicated that they reconditioned all their plastic drums. Comments were directed instead at the changes to the leak test for steel drums. The pressure required in the test has been lowered; however, the immersion period has been increased from three (3) seconds to five (5) minutes. For some companies who are currently using the recommended three (3) second immersion as their testing procedure instead of an equivalent method (only one company indicated use of the recommended three (3) second immersion), this change from three (3) second immersion to five (5) minutes diminishes their production. Those companies, however, could be opting for equivalent and more efficient tests.

For the standard on rail, CGSB-43.147, the proposed section 5.9 generated comments from the stakeholders because the criteria are different from some that the Association of American Railroads use in manufacturing, that is, one per cent of the tank inside diameter. Most commenters agreed that the proposal in section 5.9 is safer and has little economic impact.

Further consultation on the Transport Canada website and with members of the Federal-Provincial/Territorial Task Force and the General Policy Advisory Council raised no additional comments.

Implementation, enforcement and service standards

Compliance with these changes would be accomplished through the existing inspection network. The network includes both federal and provincial inspection forces who inspect all modes of transport and all consignors of dangerous goods. The inspectors need to be made aware of the changes.
