MOECC Amends Greenhouse Gas Emission Reporting Regulation to Support Future Cap and Trade Program

The amendments were enacted 1 January 2016 and include:

  • lowering the activity threshold release from 25,000 tonnes to 10,000 tonnes CO2e/year. This will capture many more emitters than previously.
  • including more activities required to report (petroleum product suppliers, equipment used for natural gas transmission, electricity imports, electricity transmission, magnesium production and mobile equipment).
  • requiring verification audits for emissions greater than 25,000 tonnes.
Note that the activity “general stationary combustion” is likely to be the largest group of reporters and may now encompass institutional facilities such as hospitals and universities. Emission calculations require data on fuel usage as well as (for some fuels) periodic analyses.

Emission calculation methods have been aligned with Quebec and California to allow emission credits to be traded between jurisdictions.

Proposed Updates to Guidance Supporting the Local Air Quality Regulation (O. Reg. 419/05)

The MOECC has proposed various updates to guides used in support of O. Reg. 419/05. The proposals are loaded on to the EBR and comments are accepted until 16 February 2016.

Some highlights of proposed changes include: Procedure Document (governing ESDMs): (i) the air emission assessment methods are no longer cited as a self-contained test for adverse effects, (ii) now clarifies that other contaminants, apart from metals, that may exist within fugitive dusts (e.g., road dusts), must be modelled, (iii) encourages facilities to specifically account for time varying emissions even for contaminants standards with longer (>= 24 hrs) averaging periods (this corrects a criticism that averaging emissions over long periods may cause underestimated POI values), , (iv) description of assessment values for contaminants with annual standards is now included, and, (v) operations historically considered insignificant must now be assessed (e.g., maintenance welding).

Air Dispersion Modelling Guideline: (i) Facilities within 1 km of a large lake or body of water should use the SCREEN3 test for shoreline fumigation (and thus suggest use of an alternative model to account for shoreline fumigation, (ii) guidance is provided on modelling approaches to emissions from roadways and haulroads (road dust).

National Pollutant Release Inventory

Reminder that several changes are in effect for the 2014/2015 reporting years (2015 report due 1 June 2016):

  • 2-(2-Methoxyethoxy)ethanol (CAS RN 111-77-3) has been added to the list of Schedule 1, Part 1, Group A substances
  • Thallium (and its compounds) has been added to the list of Part 1, Group B substances
  • Eight substances or substance groups have been moved from Part 1, Group A to Part 1, Group B. The mass threshold for these substances has been reduced from 10 tonnes, and, in some cases, the concentration threshold has been reduced from 1%: Acrylonitrile, Bisphenol A, Hydrazine (and its salts), Isoprene, Nonylphenol and its ethoxylates, Toluene-2,4-diisocyanate, Toluene-2,6-diisocyanate, and, Toluenediisocyanate (mixed isomers).
  • Quinoline (CASRN 91-22-5) has been moved from Part 1, Group A to Part 2 (polycyclic aromatic hydrocarbons)
  • Five substances have been removed from the Part 1, Group A list. NPRI reporting requirements no longer apply to these substances: Allyl chloride, C.I. Solvent Orange 7, 3-Chloro-2-methyl-1-propene, Ethyl chloroformate, and, 1-Bromo-2-chloroethane.
  • The requirement to report releases to land and water, disposals and transfers for recycling for total reduced sulphur has been removed. Only releases of total reduced sulphur to air are required to be reported.

Recent Airzone News and New Projects

Airzone has assisted a natural stone manufacturer with application for an ECA (Air and noise). Included in the air assessment were fugitive emissions from stone cutting.

Airzone continues to assist a kitchen cabinet manufacturer with NPRI and TRA reporting, as well as TRA plans, which involves, in large part, assessment of organic solvents.

Staff members have been retained to provide an overview of odour-related regulations in Ontario as it pertains to emissions from a waste-water treatment plant.

Airzone has also been retained to assist in an application for an ECA (air and noise) for a new flour mill and amendments to an existing flour mill; the latter includes updates to the air assessment to utilize the US EPA AERMOD model (which will be phased-in by 2020).

Various staff members were included in a project to assess the impacts of spontaneous coal combustion on on-site worker inhalation safety for a coal storage and shipping facility. This project involved (i) flux chamber tests with various coal-types to identify and quantify contaminant emissions, (ii) dispersion modelling with a novel source configuration developed within AERMOD, and, (iii) comparison of results against worker exposure standards.

We continue to provide EPA permitting services (ECAs and EASRs) for various clients for emergency generators.

Airzone continues to provide air monitoring services for a soil remediation site in southern Ontario.
