Foreword

This document, “Environmental Activity and Sector Registry - Limits and Other Requirements, July 1, 2021 version 3.0” (the EASR publication) sets out the requirements that facilities must follow if its activities are registered under the Air Emissions EASR Regulation.

A reference to “the Regulation” in this EASR publication is a reference to Ontario Regulation 1/17 entitled: Registrations Under Part II.2 of The Act — Activities Requiring Assessment of Air Emissions. Note that the Regulation incorporates-by-reference certain requirements of the EASR publication into the Regulation and therefore this document should be read together with or in conjunction with the Regulation.

The EASR publication includes requirements for in-stack limits for combustion equipment, noise, odour, small wood-fired combustors and combustion turbines. It also includes a list of off-grid and remote facilities/communities for the purposes of subsection 13 (2)2.ii and iii of the Regulation.

Additional guidance material is available to clients to support the completion of documents required by this Regulation, including:

Commissioning date

means the first day on which a combustion turbine begins to produce electricity or mechanical drive power.

Commissioning period

means the 90-day period following the commissioning date.

3. The ambient air temperature is greater than or equal to -18°C.
4. The emission samples must be taken from a sampling port that meets the specifications set out in the Ontario Source Testing Code as amended from time to time.

4. The statement mentioned in paragraph 3 of section 31.1 of the Regulation must confirm that the installation test was conducted in accordance with the following requirements:

1. Before the end of the commissioning period of any combustion turbine system, an installation test must be performed to determine if the combustion turbine system is operating below the appropriate emission concentration limits set out in Chapter 1 for CTs.
2. The combustion turbine system emissions must be measured for a minimum of one (1) hour according to the operating conditions set out in section 2 and emissions of nitrogen oxides (NO_x), carbon monoxide (CO) and oxygen (O₂) measured according to the methodology described in ASTM D6522-20 with a portable combustion gas analyzer.
   1. Portable combustion gas analyzers must be selected and operated according to the methodology and equipment requirements described in ASTM D6522-20.
   2. Emission levels must be calculated as integrated averages on an hourly basis with a known date and time reference concurrent with the energy quantification data described in section 2 and are to be compared with the appropriate emission concentration limits set out in Chapter 1 for CTs and documented.
3. If the combustion turbine system has a maximum power output capacity of 1 MW or greater, or if the exhaust ventilation ductwork is combined for two or more CTs, then the installation test must be verified by a licenced engineering practitioner (LEP) to ensure that the operating conditions set out in section 2 are met.
   1. If each CT discharges to its own dedicated exhaust stack and has a maximum power output capacity of less than 1 MW then this additional oversight by an LEP is not required although the operating conditions set out in section 2 are required to be met.
4. The thermal efficiency must be determined on an hourly basis using the continuously monitored energy parameters described in section 2 and calculated as per the equation below:
    

   Thermal Efficiency (%) = 100 × (PO + HO) / HI
   where:
   PO = power output (GJ/hr)
   HO = heat output (GJ/hr)
   HI = heat input (GJ/hr)

5. Thermal efficiency on-site testing must verify the correct operation of the energy quantification devices set out in section 2 and the operator must follow the recommendations of the technology provider of the combustion turbine system to ensure the GPL is achieved. The thermal efficiency must be verified by an LEP during the installation test, unless each CT discharges to its own dedicated exhaust stack and has a maximum power output capacity of less than 1 MW, then this additional oversight by an LEP is not required.
6. For combustion turbine systems with a PO of 5 MW or greater, the Ministry requires that the thermal efficiency be verified using one of the following standards:
   1. ISO 2314:2009 entitled “Gas turbines – acceptance tests”, or
   2. ISO 18888:2017 entitled “Gas turbine combined cycle power plants – Thermal performance tests”.
7. An installation test report must be prepared to document the emission data and thermal efficiency verification from the installation test, whether oversight by an LEP is required or not.
   1. Where oversight by an LEP is required, the report must be dated, signed and sealed by an LEP and set out the practitioner’s name and licence number. The information in the report must be accurate as of the date it is signed and sealed.

Performance assessment

5.  The statement mentioned in paragraph 4 of section 31.1 of the Regulation must confirm that the performance assessment

1. A performance assessment must be conducted on a combustion turbine system at least once every 2 years to ensure that the equipment is continuing to operate in a manner which is consistent with the GPL from the technology provider and determine if the combustion turbine system is operating below the appropriate emission concentration limits set out in Chapter 1 for CTs.
2. During performance assessment testing, the combustion turbine system must be operated for a minimum of one (1) hour according to the operating conditions set out in section 2 with emissions of NO_x, CO and O₂ measured with a portable combustion gas analyzer.
   1. Portable combustion gas analyzers must be selected and operated according to the methodology and equipment requirements described in ASTM D6522-20.
   2. Emission levels must be calculated as integrated averages on an hourly basis with a known date and time reference concurrent with the energy quantification data described in section 2 and are to be compared with the appropriate emission concentration limits set out in Chapter 1 for CTs and documented.
3. If the combustion turbine system has a maximum power output capacity of 1 MW or greater, or if the exhaust ventilation ductwork is combined for two or more CTs, then the performance assessment must be verified by an LEP to ensure that the operating conditions set out in section 2 are met.
   1. If the CT discharges to its own dedicated exhaust stack and has a maximum power output capacity of less than 1 MW then this additional oversight by an LEP is not required although the operating conditions set out in section 2 are required to be met.
4. The thermal efficiency must be determined as described in section 4 and the thermal efficiency must be verified by an LEP during the performance assessment as described in section 4 unless the CT has a maximum power output capacity of less than 1 MW then this additional oversight by an LEP is not required.
5. A performance assessment report must be prepared to document the emission data and thermal efficiency verification from the performance assessment, whether oversight by an LEP is required or not.
   1. Where oversight by an LEP is required, the report must be dated, signed and sealed by an LEP and set out the practitioner’s name and licence number. The information in the report must be accurate as of the date it is signed and sealed.
