National Pollutant Release Inventory 2005
Are you required to report ?

Disclaimer: This brochure is intended to determine if your facility is required to report to Environment Canada for the 2005 National Pollutant Release Inventory on or before June 1, 2006. For the complete reporting requirements, refer to the Notice with Respect to Substances in the National Pollutant Release Inventory for 2005, published on February 19, 2005 in the Canada Gazette, Part I.

What is the National Pollutant Release Inventory (NPRI)?

The NPRI is a Canadian database containing information on annual on-site releases of specific substances to the air, water and land, as well as disposals and off-site transfers for recycling that originate from industrial and institutional sources. The NPRI is managed by Environment Canada and currently tracks 323 substances. These substances are grouped into five different parts. All NPRI data are accessible on the Internet at: www.ec.gc.ca/npri.

Is reporting to the NPRI a legal requirement and mandatory under Canadian Law?

YES. The NPRI is not a survey or voluntary program. The legal authority for the NPRI is the Canadian Environmental Protection Act, 1999 (CEPA 1999), subsection 46(1).

How do I determine if I must submit a 2005 NPRI Report to Environment Canada?

The number of employee hours worked at your facility during the 2005 calendar year will be needed in order to determine your requirement to report to the NPRI. Your employee hour calculation should include hours worked by full-time or part-time employees and routine contractors that work at the facility, including administrative, seasonal, and sales staff based at the facility. If your facility is engaged in waste or sewage sludge incineration, wood preservation, fuel terminal operations or municipal waste water collection and treatment, you must determine if you need to report based on the substance quantity criteria described below, regardless of the number of employees working at your facility.

If you used one or more of the listed substances during 2005, you will need to determine the total amount of each NPRI substance at your facility during that calendar year. The substance may have been contained in materials used at your facility or they may have been produced as a result of your processes.

For substances contained in purchased materials or mixtures, one way to determine if you need to submit a report is to check your Material Safety Data Sheets to see if the substances listed on the following pages were used in your facility in 2005. You can use the Chemical Abstracts Service (CAS) number assigned to each substance for this process. You can also check with your suppliers for assistance.

If you indicate on the attached reply form that you may be required to submit an NPRI Report, then a 2005 NPRI reporting kit will be mailed to you during the spring of 2006. It will provide more detailed information to assist you in completing your 2005 report to Environment Canada. In addition, you can obtain the detailed 2005 NPRI reporting requirements on our web site at www.ec.gc.ca/npri.

Who do I contact if I have questions related to the NPRI?

Please contact your regional Environment Canada NPRI office as shown on the enclosed Reply Form. NPRI Information Sessions will be held in the Spring of 2006. Please consult the NPRI website to find out the locations and dates for these sessions.

Please return the enclosed Reply Form to Environment Canada before March 15, 2006.

Note: The deadline for submitting a complete 2005 NPRI Report is June 1, 2006.

What are the 2005 NPRI Substances?

The NPRI substances are grouped into five parts based on their reporting criteria. These substances were published in the Canada Gazette, Part I, on February 19, 2005.

PART 1A - Core Substances

You may need to report for substances in this section if, in 2005, they were manufactured, processed or otherwise used at your facility in a quantity of 10 tonnes or more and employees (including contractors) worked 20,000 hours or more at your facility.

Examples of facilities that typically report these substances include: wastewater facilities, oil and gas facilities, chemical, plastic and paint manufacturers, manufacturers of wood products, metal fabricators, etc.
