1.0 Summary

This report reviews how primary suppliers have responded to the Benzene in Gasoline Regulations of the Canadian Environmental Protection Act, 1999 (CEPA 1999). The Benzene in Gasoline Regulations came into effect on July 1, 1999, fulfilling a recommendation of the federal-provincial Task Force on Cleaner Vehicles and Fuels. In 1995, the Task Force recommended to the Canadian Council of Ministers of the Environment (CCME) that benzene in gasoline be reduced through a federal regulation to 1% by volume and that aromatics (or equivalent benzene tailpipe emissions) be frozen at 1994 levels. The CCME endorsed this recommendation. Consequently, the federal government passed the federal Benzene in Gasoline Regulations on November 26, 1997.

The Benzene in Gasoline Regulations have been successful in achieving both of the recommendations of the Task Force: reported benzene levels have been significantly reduced and reported aromatic levels are about the same as they were in 1994. Figure 1.1 shows how benzene and aromatics levels have changed since the coming into force of the regulations.

All primary suppliers must submit reports annually to Environment Canada reporting on the composition of the gasoline they supplied in that year (quarterly reports were required until the end of 2002). For the 2007 reporting year all primary suppliers reported that all gasoline supplied in Canada met the regulated requirements with respect to benzene concentration and benzene emissions number (BEN) with one exception respectively. Details on the exceptions can be found in Section 3.3: Reported Exceedances of Regulated Limits.

Independent audits are required for those primary suppliers that elected to be on a yearly pool average and must be submitted to Environment Canada by May 31 of the year following the reporting period. This report includes analysis of the independent audits conducted for the 2007 reporting period. Those audits found six instances of non-compliance with administrative requirements involving sampling and reporting requirements. One primary supplier outlined corrective actions taken to address these issues.

Figure 1.2 shows that average urban ambient benzene concentrations, measured at Environment Canada monitoring stations across Canada, have fallen by 73% between 1991 and 2007. Since 1998, the year prior to the regulation coming into effect, average urban and rural ambient benzene concentrations have fallen by approximately 56%.

2.0 Overview of Benzene in Gasoline Regulations

This report reviews the compliance of primary suppliers’ (refiners, importers and blenders) gasoline with the Benzene in Gasoline Regulations[1], and summarizes levels of various parameters in Canadian gasoline. The information used for this report was provided by primary suppliers, as required under the Regulations.

2.1 Benzene in Gasoline Regulations

The Benzene in Gasoline Regulations were passed in November 1997 in order to reduce emissions of benzene from gasoline-powered vehicles. The regulations limit the level of benzene and the benzene emission number (BEN)[2] of Canadian gasoline and require reporting on the composition of gasoline that is produced, imported or blended[3]. The Regulations apply to all types of gasoline for sale or use in Canada, except gasoline for use in aircraft, competition vehicles or scientific research.

All primary suppliers of gasoline must submit reports annually on the levels of various parameters of their gasoline to Environment Canada (quarterly reports were required until the end of 2002). Importers must notify Environment Canada at least 12 hours in advance of their intention to import:

The Benzene in Gasoline Regulations introduced a new approach to controlling fuel composition by allowing regulatees the option to elect to use a yearly pool average as the basis for compliance. This option is selected separately for each refining, blending facility and import pool and provides regulatees considerable flexibility in meeting the requirements of the regulations. The Regulations are chiefly focused on primary suppliers (refiners, blenders and importers) who can affect the composition of gasoline. There is also a per-litre limit for benzene at the point of sale. In addition to setting a limit for gasoline benzene content, the Regulations also set a limit for the benzene emission number (BEN) of gasoline, a number that relates gasoline composition to estimated emissions of benzene from vehicles.

The regulated limits apply to individual refineries, blending facilities, and imports into a province from outside Canada. Primary suppliers are subject to flat limits for each of their refineries, blending facilities or import pools unless they have elected for yearly pool average limits. The yearly pool average is the volume-weighted average of benzene or BEN of the gasoline supplied by the primary supplier during a year and may be selected for either benzene, BEN, or both. Independent audits must be submitted to Environment Canada by primary suppliers who elect to be on a yearly pool average.

Since July 1, 1999, primary suppliers have been subject to limits on the level of benzene and the BEN in the gasoline they produce, blend or import. Table 2.1 summarizes the regulated limits for benzene and the BEN.

2.2 Alternative Limits for the BEN

Under subsection 17(2) of the Regulations, a primary supplier may have elected before December 1, 1998 to use alternative (higher) limits for the BEN. Petro-Canada and Shell elected to use alternative (higher) limits for the BEN at their Ontario and Quebec refineries. Their alternative limits were set out in a Notice published by the Minister of the Environment in the Canada Gazette on September 4, 1999 (see Appendix 2).

These alternative limits were based on the historical composition of the primary supplier’s gasoline, thereby reflecting its historical BEN number. There is no expiry date for alternative BEN limits, although a primary supplier may rescind the alternative limit at any time. A supplier rescinding its alternative limit would then be subject to the normal limits for BEN. These can be found in Appendix 2 (CGI, Vol.133, No.36).

3.0 Compliance with the Regulations

3.1 Primary Suppliers and the Options to Meet Requirements

Primary suppliers are required to register with Environment Canada using the Registration Form for a Manufacturer, Blender or Importer of Gasoline (see Appendix 1). Table 3.1 shows the primary suppliers who were registered with Environment Canada[4] and reported supplying gasoline during 2007 indicating their choice for either a “Flat” (flat per-litre limit) or “YPA” (yearly pool average) as the basis of compliance with the benzene and BEN limits.

3.2 Information Reported

Under section 8 of the regulations, primary suppliers must provide the information set out on the form entitled Report on the Composition of Gasoline (see Appendix 1) before February 15th of the following year. Prior to 2003, the reports were submitted quarterly. After 2003, it was mandatory that reports are to be submitted before February 15 of the following year.

In addition to the volume of gasoline supplied (m3), the number of batches supplied and the names of any oxygenates added, the regulations require that primary suppliers also report the maximum and year-to-date average values[5] for the following parameters:

3.3 Reported Exceedances of Regulated Limits

For primary suppliers using flat limits (R= refiner, I= importer, B=Blender), Figure 3.1 shows the reported maximum and average benzene level and Figure 3.2 shows the reported maximum and average BEN.

Figure 3.1: Reported Benzene Levels (Maximum and Average) for Suppliers on a Flat Limit, 2007
Figure 3.1: Reported Benzen Levels (Maximum and Average) for Suppliers on a Flat Limit, 2007

Click here to see the picture in full-size

As shown in Figure 3.1 there was one exceedance of the benzene flat limit of 1.0% by an importer who elected for flat limits (General Motors in Ontario). The benzene limit was exceeded by a single shipment of gasoline to a facility which was reported at the time of occurrence directly to Environment Canada. During a provincial shortage of gasoline, General Motors switched suppliers and was sent a single batch of gasoline that did not meet the specifications by General Motors nor the requirements of the Benzene in Gasoline Regulations. All other imported fuel by General Motors was compliant[6].

As shown in Figure 3.2 there were no exceedances of the seasonal BEN limits by a flat-limit supplier in the year 2007.

For primary suppliers using YPA limits, Figure 3.3 shows the reported average and maximum benzene levels and Figure 3.4 shows the reported average BEN as a percentage of the regulated limit (59.5 YPA). The yearly pool average data from Figures 3.3 and 3.4 represent the volume weighted average for all gasoline from a given primary supplier during the year.

One annual report received by Environment Canada contained reported maximum benzene levels that exceeded the Benzene limit of 1.5% (never-to-be-exceeded-cap) as shown in Figure 3.3. An explanation of this reported exceedance was documented in the independent audit report submitted by the primary supplier. This audit report documented one instance where a batch of gasoline used in the yearly pool average calculation had a benzene concentration above 1.5% (by volume). The following extract is the auditor’s description of this instance:

Chevron Canada Burnaby – “There was a deviation noted for an exceedance of Benzene (batch# 07 – 001), the regulations required benzene content with a never to be exceeded cap of 1.5%, batch# 07-001 was confirmed as 1.6%. CCL has investigated and implemented corrective action as documented in the incident report (Ref# 1327).”

One annual report received by Environment Canada contained a reported yearly pool average BEN which exceeded the cap (59.5) as shown in Figure 3.4. An explanation of this reported exceedance was documented in the independent audit report submitted by the primary supplier. This audit report documented that there was only one batch processed at the facility, which had a BEN within the maximum BEN cap but exceeding the average BEN cap. The following is the auditor’s description of the instance:

Petro Canada Burrard – “There was a deviation for an exceedance of yearly pool average of BEN at Burrard Products Terminal, Burnaby BC. The Regulations required BEN with YPA not to exceed 59.5; however, there was only one batch received in 2007 (BEN was 64, Ref. Cargo ITB Groton). Hence the YPA of BEN was 64 which exceeded maximum of 59.5.”

3.4 Summary of 2007 Independent Audits

Under section 22 of the regulations, a primary supplier that has elected to use a yearly pool average as its basis for compliance must have an independent auditor perform an audit of the primary supplier’s systems, practices and procedures and its compliance with the regulations.

The auditor’s report must be submitted to Environment Canada by May 31 of the year following the reporting period. Environment Canada views the audits as a crucial component of the enforcement provisions of the regulations and, to be effective, the auditing process must be independent and thorough. The concept of a yearly pool average relies on the maintenance of complete records and reports. The audits are intended to provide Environment Canada assurance that the yearly pool averages are being correctly reported. This section contains the analysis of the Independent Audits submitted for the 2007 reporting period.

For the 2007 reporting year, ten audits were submitted by six companies in regard to eleven refineries, four import pools and one blending facility. Nine of these audits were combined audits capturing the audit requirements for both the Benzene in Gasoline Regulations and the Sulphur in Gasoline Regulations. The audits were conducted by two audit companies.

Paragraph 22(3)(e) of the Regulations requires that the audit contain: “an assessment by the auditor of the extent to which the primary supplier has complied with these Regulations throughout the year of the audit.” The 2007 audits indicate that all primary suppliers subject to audits met the regulated limits for benzene concentration and BEN with the exception of two specific batches prepared by different companies.

Three audit reports identified one or more instances of minor non-compliance with the administrative requirements of the regulations, for a total of six instances of non-compliance. Two companies accompanied the audit report with a list of corrective actions that have been taken by the primary supplier, covering three of the six instances of non-compliance.

Two audit reports identified instances of non-compliance with the regulated limits for Benzene concentration and BEN. One company reported taking corrective action covering one of the two instances of non-compliance.

Instances of minor non-compliance involved sampling and reporting requirements. With respect to sampling, instances of non-compliance included:

With respect to the annual reports required by the regulations, instances of non-compliance included:

Several recommendations for improvements were made by auditors in one of the evaluation reports. These recommendations were made relating to:

Environment Canada views the audits as a crucial component of the enforcement provisions of the regulations and, to be effective, the auditing process must be independent and thorough. The concept of a yearly pool average relies on the maintenance of complete records and reports. The audits are intended to provide Environment Canada assurance that the yearly pool averages are being correctly reported.

Figure 4.1 shows the graphical trend in benzene levels between 1995 and 2007 for Canada, both nationally and by region[7]. As the Regulations took effect mid-1999, the data for the year 1999 is presented separately for the first and second half of the year. Nationally, benzene levels in 2007 were half of those between 1995 and 1998.

Figures 4.2 and 4.3 show the regional and national average values for benzene concentrations and BEN, respectively.

4.3 Reported Oxygen Concentration

Primary suppliers are required to report the type of oxygenate that they use and the oxygen concentration of the gasoline produced or imported. Tables 4.3 and 4.4 summarize the concentrations of MTBE and ethanol, respectively, based on the reported oxygen concentrations and type of oxygenate. Since 2000, the average level of MTBE reported in gasoline produced and imported has decreased to negligible amounts. The average concentration of ethanol in gasoline that was reported for 2007 showed an 18% decrease from 2006 levels. The data presented here does not include oxygenates that are blended downstream of the refinery or point of import. As a result, these values are likely to be underestimates of the usage of oxygenates in Canadian gasoline.

4.4 Trends of Aromatics and Olefins

From 1994 to 1998, data on the benzene, aromatic and olefin concentrations in gasoline were collected by Environment Canada under a voluntary survey. Olefin concentrations were added to this survey in 1997. When gasoline is combusted in the vehicle’s engine, aromatics in the gasoline can form benzene (a known human carcinogen), while olefins can form 1,3-butadiene (a probable human carcinogen).

Trends for aromatics and olefins content are shown in tables 4.5 and 4.6, respectively[8]. These data show that 2007 national reported levels of aromatics have slightly decreased since 2006. Similarly, levels of olefins have slightly decreased since 2006 and remain among the lowest reported levels since 1997.

4.5 Comparison of Imported vs. Domestic Gasoline

Table 4.7 compares the data provided by refiners and importers. As was shown in Table 3.1, flat limits were selected by the majority of importers while the YPA option was selected by the majority of refiners. As shown in Table 4.7, importers reported lower maximum values for all parameters except for distillation parameters E200 and E300, and olefins.

5.0 Other Gasoline Quality Information

5.1 The Gasoline Regulations

The Regulations respecting concentrations of lead and phosphorus in gasoline (The Gasoline Regulations)[9] limit the concentration of lead in gasoline that is produced, imported, sold or offered for sale in Canada to 5 mg/L and limit the concentration of phosphorus in unleaded gasoline to 1.3 mg/L. Gasoline for use in aircraft is exempt from the Regulations and, until January 1, 2010, gasoline for use in competition vehicles is not subject to the lead concentration restrictions.

The Gasoline Regulations were passed in 1990, virtually eliminating the use of lead additives in gasoline. The Regulations were passed in response to the 1986 Royal Society of Canada Commission on Lead in the Environment, which recommended to the Government of Canada that “Public health and environmental policy should be to reduce blood lead to its lowest possible level”. Of particular concern were emissions of lead particles to the atmosphere, of which the largest source was gasoline lead particulates from the combustion of tetraethyl lead and tetramethyl lead, antiknock additives that were commonly used in gasoline.

Under the Gasoline Regulations, producers, importers or sellers of leaded gasoline must submit reports (see Appendix 1) to the Minister of the Environment as follows:

For the 2007 reporting period, nine companies submitted records of imports of leaded gasoline for use in competition vehicles totalling 1,170,424 Litres. Eleven companies submitted records of leaded gasoline sales. The reported average lead concentrations of that gasoline ranged from 0.0001 to 2113.6 mg/L. Table 5.1 summarizes the number of companies reporting imports of leaded gasoline for use in competition vehicles for each region in 2007.

These regulations apply to importers, manufacturers and blenders of gasoline. They also apply to anyone that sells gasoline or offers it for sale.

The regulations prohibit the production or import of gasoline with a benzene content exceeding 1.0% by volume. They also restrict the Benzene Emissions Number (BEN), a calculated parameter that relates gasoline composition to predicted emissions of benzene from vehicle tailpipes to a maximum of 71 in the summer and 92 in the winter. Companies may elect to meet annual pooled averages for benzene and BEN, in place of the above limits.

The regulations also prohibit the sale of gasoline with more than 1.5% by volume of benzene.

Various reporting and record-keeping requirements are specified in different sections of the Regulations. For instance:

Appendix 2: Alternative Limits under the Benzene in Gasoline Regulations

Canada Gazette Part I, Vol. 133, No. 36
September 4, 1999

GOVERNMENT NOTICES

DEPARTMENT OF THE ENVIRONMENT

Alternative Limits under the Benzene in Gasoline Regulations

This notice provides information on alternative limits that have been approved by the Minister of the Environment under the federal Benzene in Gasoline Regulations.

The federal Benzene in Gasoline Regulations set limits for the level of benzene in gasoline and for a parameter called the benzene emissions number (BEN). The BEN relates gasoline composition to the estimated emissions of benzene from vehicles. The limits under the Regulations came into effect on July 1, 1999.

Under subsection 17(2) of the Benzene in Gasoline Regulations, primary suppliers of gasoline (refiners, blenders and importers) could elect to be subject to alternative limits for the BEN, based on their historical gasoline composition. Under subsection 16(2), primary suppliers unable to meet the July 1, 1999, implementation date could also apply to be subject to temporary (higher) limits for both benzene and the BEN for up to six months.

Temporary Limits under Subsection 16(2)

Under subsection 16(2) of the Regulations, primary suppliers may apply for temporary alternative limits for benzene and the BEN if, for reasons beyond their control, they cannot meet the implementation date of July 1, 1999. Primary suppliers may only use the temporary limits until December 31, 1999. Under subsection 16(4) of the Regulations, the Minister of the Environment approves these applications only if:

In the Regulatory Impact Analysis Statement that accompanied amendments to the Benzene in Gasoline Regulations, published in the Canada Gazette, Part II, on May 26, 1999, the Minister of the Environment announced her intention to "publish a notice in Canada Gazette Part I identifying the company, its alternative limits, and the period that the limits apply". Pursuant to that intention, the following tables show the temporary alternative limits for benzene and the BEN that have been applied for and approved. It should be noted that under the Regulations, companies can elect to meet the requirements on the basis of yearly pool average limits with associated never-to-be-exceeded caps, rather than meeting "flat" never-to-be-exceeded limits.

Temporary Limits for Primary Suppliers having Elected to use Yearly Pool Averages

Standard limits under subsection 3(1) and section 4

Standard limits 1.0% 71/92  

Notes:

Under paragraph 3(2)(b) of the Regulations, the areas where gasoline sold is subject to temporary alternative limits are:

In the above areas, the prohibition on selling (as opposed to manufacturing, blending or importing) gasoline containing benzene at a concentration that exceeds 1.5 percent by volume is deferred from October 1, 1999, to April 1, 2000.

Alternative Limits for BEN under Subsection 17(2)

Under subsection 17(2) of the Regulations, primary suppliers may elect for alternative limits for the BEN based on the historical composition of their gasoline. There is no expiry date for alternative BEN limits.

In the Regulatory Impact Analysis Statement that accompanied the Benzene in Gasoline Regulations, published in the Canada Gazette, Part II, on November 26, 1997, the Minister of the Environment announced her intention that the alternative limits "will be publicly available and will be published by Environment Canada". Pursuant to that intention, the following alternative limits for the BEN have been applied for and approved:

Alternative Limits for BEN
  Benzene Emissions Number
Company Refinery Alternative yearly pool average limit Alternative never-to-be-exceeded cap (summer/winter)
