2010 NPRI Reviewed Facility Data Release

---

4. Pollutant Releases, Disposals and Recycling Reported to the NPRI for 2010 (continued)

Table 4.2: Part 1B – Metals listed at an alternate threshold

Substances listed in Part 1B of the Notice can have significant environmental and human health impacts at relatively low levels. Since minimal releases of Part 1B substances may result in adverse effects, the reporting thresholds for Part 1B substances are lower than those for Part 1A substances.

The types of facilities and sectors that reported the largest amounts of releases and transfers of the Part 1B substances for 2010 include metal ore mines, waste treatment and disposal facilities, metal smelters, metal plating facilities, oil sands facilities and electric power stations.

Table 4.3: Part 2 – Polycyclic aromatic hydrocarbons (PAHs)

Facilities must report Part 2 substances if they meet the following two criteria:

1. The facility unintentionally manufactured, and released, disposed or transferred a Part 2 substance from a facility in a combined quantity of 50 kilograms or more;
   and
2. Employee hours at the facility totalled 20 000 or more.

It is important to note, however, that wood preservation facilities using creosote must report Part 2 PAHs regardless of the quantity released.

Examples of facilities that report Part 2 substances include those in the aluminum industry, oil and gas facilities, pulp and paper mills, cement manufacturers, electricity generating stations and wood preservation facilities. They may also be contained in tailings. Note: Two PAHs (anthracene and naphthalene) are listed in Part 1A of the NPRI substance list, given that they are commercial chemicals used in large amounts, rather than unintentionally produced by-products.

Table 4.4: Part 3 – Dioxins, furans and hexachlorobenzene

Polychlorinated dibenzo-p-dioxins (PCDDs, i.e., dioxins), polychlorinated dibenzofurans (PCDFs, i.e., furans) and hexachlorobenzene (HCB) are released primarily as by-products of industrial and combustion processes, but are also found as contaminants in certain pesticides or chlorinated solvents. HCB may also be found as a contaminant in ferric chloride used for water or wastewater treatment. These substances have been identified as toxic under CEPA 1999 and are slated for virtual elimination.

Facilities must report Part 3 substances if they engage in specific activities, regardless of the quantities and concentrations. These activities include incineration, cement manufacturing, metal smelting, iron and steel manufacturing, pulp and paper manufacturing, chlorinated solvent production, power generation and wood preservation.

Note: The total values for dioxins and furans (in grams I-TEQ) above represent the weighted sum of the 17 individual congeners listed on the NPRI as well as the total dioxins and furans reported as a group in cases where information on individual congeners is not available. Since the 2007 reporting year, facilities have been required to report on each of these congeners separately, in grams. The applicable International Toxicity Equivalency (I-TEF) factors for the individual congeners are provided for reference purposes. Additional information about toxicity equivalence factors for dioxins and furans is available in the 2010 Guide for Reporting to the NPRI.

Table 4.5: Part 4 – Criteria air contaminants

NPRI Part 4 substances are criteria air contaminants (CACs), the major air pollutants contributing to smog, acid rain and poor air quality.

Facilities must report Part 4 substances released to the air in quantities equal to or exceeding the reporting thresholds quantities. Facilities with more than 20 000 employee hours must consider all sources of CACs. In addition, facilities must report CACs regardless of the number of employee hours for stationary combustion equipment, and for road dust if vehicles travelled more than 10 000 kilometres on unpaved roads at the facility.

The types of facilities and sectors that reported the largest amounts of releases and transfers of the CACs for 2010 include facilities with boilers that burn fuels or waste; oil and gas facilities; aluminum production and processing facilities; pulp and paper mills; electricity generation stations; mines, pits and quarries; cement manufacturers; and sawmills and wood products facilities.

*	Volatile Organic Compounds (VOCs)	250 432

Table 4.6: Part 5 – Speciated volatile organic compounds

Speciated VOCs are primary precursors to the formation of ground‑level ozone and particulate matter in the atmosphere, the main ingredients of smog. Part 5 substances include individual substances, isomer groups and other groups and mixtures. 

The key reason for collecting emission data on speciated VOCs is for use in regional air quality modelling. The data also serves various domestic and international programs requiring information on trends and forecasts of emission data.

Part 5 substances must be reported if they are released to air in a quantity of one tonne or greater, and if they meet the 10‑tonne air release threshold for total VOCs under Part 4.
