Coal-Fired Boiler Emission Guidelines 2005

Last Updated: August 2005

Introduction

All new thermal power generation projects, as well as existing facilities that are undergoing significant modifications, are required to install control technologies that will, at a minimum, achieve these emission guidelines. Depending on the project and site, and if an adverse impact to the receiving environment is anticipated, more stringent control of emissions, beyond the guidelines listed here, may be deemed necessary by the Ministry of Environment.

Coal-Fired Power Boilers

Table 1: Limits for Gaseous and Particulate Emissions from New Coal-Fired Boilers

Notes:

1. A comparison with guidelines and standards in other jurisdictions may be found in these tables. The tables provide comparisons in input-based units, as well as output-based units.
   
2. The values for total particulates, nitrogen oxides and sulphur dioxide are on a 30-day rolling average basis.
   
3. Based on the Canadian Council of Ministers for the Environment's (CCME's) Canada-wide Standards for Mercury Emissions from Coal-fired Electronic Power Generation Plants.

Continuous monitoring of sulphur dioxide, nitrogen oxides and oxygen or carbon dioxide contents in the flue gas will be required. Any additional monitoring and source testing requirements will be determined by the Ministry of Environment on a case-by-case basis.

No limits have been specified for polycyclic aromatic hydrocarbons or certain other reactive substances. Appropriate specifications will be established by the Ministry of Environment should such a need develop. The degree of control necessary for polycyclic aromatic hydrocarbons or certain other reactive substances may also require a further reduction of total particulate emissions.
