Government of Canada, Environmental Emergency (E2) Regulatory Information

The Government of Canada has recently changed the reporting requirements for any person or company in Canada who owns or manages certain substances (so far it affects 174 different substances) over certain quantities. Anhydrous ammonia and ammonium hydroxide (aqua ammonia) are on the substance list if you have tank capacity over the following amounts;

Anhydrous Ammonia

4.5 tonnes (4,500 kg. or 1,918 USWG)

Ammonium Hydroxide (Aqua Ammonia)

Solution Strength Tank Capacity
Less than 20% No Requirement
26% Solution 35 tonnes (35,000 kg. or 10,191 USWG)
30% Solution 30.3 tonnes (30,300 kg. or 8,937 USWG)

Note: Volume is calculated at a temperature of 60 F.

In the event you have a tank capacity over these thresholds, the E2 Plan will affect you. It does not matter if you only fill your tank to 50% of the total capacity. If your storage vessel has tank capacities over these thresholds, you need to file an E2.

What is involved if you have storage capacity equal to or in excess of these levels? You need to;

  1. Submit a notice of "Identification of Substance and Place". The due date of this was Feb. 16, 2004 so your immediate attention to this is very important.
  2. Prepare an E2 plan and submit a "Notice of Preparation" by May 18, 2004.
  3. Implement and test the E2 Plan and submit a "Notice of Implementation" by November 18, 2004.
  4. Test your plan annually and keep records for a minimum of 5 years.

It is possible to have 2 smaller tanks (under the above threshold) in place of larger vessels.


A facility has 20 tonnes of anhydrous ammonia on site. There are 5 tanks, each tank with 4 tonnes capacity, all connected to each other. Total plant capacity is over the threshold of 4.5 tons but it is shared between five 4 tonnes tanks.

In this case, the facility is affected by the E2 regulation, but only the first part or "Notice of Identification of Substance and Place" is required. Our interpretation is this facility would not need to prepare and implement an E2 plan because the largest single container for the substance does not exceed the threshold limit. Notwithstanding, normal safety procedures would still be required.

In the event you need more information or guidance or are unsure if the new plan affects you, the plan may be found at www.cepae2.ec.gc.ca. Please feel free to call Anco regarding questions or guidance.
