Guidelines for the Reduction of Nitrogen Oxide Emissions from Natural Gas–fuelled Stationary Combustion Turbines

November 2017

1. Foreword

The development of the Guidelines for the Reduction of Nitrogen Oxide Emissions from Natural Gas–fuelled Stationary Combustion Turbines (henceforth “the Guidelines”), published under section 54 of the Canadian Environmental Protection Act, 1999 (CEPA), follows the agreement made by federal, provincial and territorial environment ministers to better protect human health and the environment by endorsing and implementing a new Air Quality Management System (AQMS). The AQMS includes Canadian Ambient Air Quality Standards for fine particulate matter and ground-level ozone, Base-level Industrial Emissions Requirements (BLIERs) and local Air Zone Management by the provincial/territorial jurisdictions.

Environment and Climate Change Canada led a multi-stakeholder BLIERs working group that developed consensus-based NO_x emission requirements for new natural gas–fuelled stationary combustion turbines. These requirements form the foundation for the emission limits in the Guidelines.

The Guidelines introduce an NO_x emission limit that is up to 50% more stringent than emission limits set out in the National Emission Guidelines for Stationary Combustion Turbines published by the Canadian Council of Ministers of the Environment (CCME) in 1992.

The Minister of Environment and Climate Change recommends that the appropriate regulatory authorities adopt the Guidelines as a baseline emission limit for NO_x from natural gas–fuelled stationary combustion turbines. However, the Guidelines do not prevent provinces or territories from setting more stringent emission requirements for combustion turbines via their own policies. As well, the Minister of Environment and Climate Change continues to recommend those requirements of the 1992 CCME Guidelines that have not been superseded by the requirements in this document.

2. Definitions

The following definitions apply in these Guidelines:

“Calendar year” means the period of 12 consecutive months that begins on January 1.

“CFR” means Title 40, Chapter I of the Code of Federal Regulations of the United States.

“Cogeneration” means the integrated operation of one or more combustion turbines and steam generators that recover any heat from combustion turbine exhaust gases to supply steam for useful purposes other than electricity generation (e.g. to a heating system or an industrial process).

“Combined cycle” means the integrated operation of one or more combustion turbines and steam turbines for the production of electricity using the same source of thermal energy.

“Combustion turbine” means an engine that operates according to the Brayton thermodynamic cycle, which burns fuel and allows the products of combustion at a high temperature to expand through a rotating power turbine to produce motive power.

“Commissioning date” means the first day on which a combustion turbine begins to produce electricity or motive power.

“Continuous Emissions Monitoring System (CEMS)” means equipment for the sampling, conditioning and analyzing of emissions from a given source and recording of data related to those emissions.

“Emergency combustion turbine” means a combustion turbine that operates only in emergency situations, including to produce power for critical networks or equipment during electric power interruptions, to pump water in the case of fire or flood, or for equipment or facility re-start.

“Natural gas” means a naturally occurring fluid mixture of hydrocarbons (e.g. methane, ethane or propane) produced in geological formations beneath the Earth's surface that maintains a gaseous state at standard atmospheric temperature and pressure under ordinary conditions. Natural gas is composed of at least 85% methane by volume, and it excludes landfill gas, digester gas, refinery gas, sour gas, blast furnace gas, coal-derived gas, producer gas, coke oven gas or any gaseous fuel produced in a process that might result in highly variable sulphur content or heating value.

“New combustion turbine” means a combustion turbine whose commissioning date is on or after January 1, 2020.

“Nitrogen oxide (NO_x)” means oxides of nitrogen, which is the sum of nitric oxide (NO) and nitrogen dioxide (NO₂).

“Operator” means a person who has the charge, management or control of a combustion turbine.

“Part-load operation” means the operation of the combustion turbine below 70% of its power rating.

“Peaking combustion turbine” means a combustion turbine that is operated for 1 500 hours or less within a calendar year.

“Power rating” means normal maximum continuous rating (in megawatts — MW) at International Organization for Standardization (ISO) 3977-2 environmental design point conditions of ambient air: 15°C (288K), 60% relative humidity and 101.3 kilopascals barometric pressure.

“Predictive Emission Monitoring System (PEMS)” means all of the equipment and related activities required to determine an emission concentration or an emission rate. This may include processor control devices, sensors, operating parameter measurements, conversion equations, graphs or computer programs to produce results in units of the applicable emission limit or standard.

“Shut-down period” means the period of time between the moment when the combustion turbine is operating at normal operating mode and the moment when it is non-operational.

“Simple cycle combustion turbine” means a combustion turbine that operates without harnessing the turbine exhaust heat for useful purposes.

“Start-up period” means the period of time between the moment when the combustion turbine is non-operational and the moment when it is operating at normal operating mode.

3. Scope

• 3.1. Subject to sections 3.2 and 3.3, these Guidelines set NO_x emission limits for new combustion turbines with a power rating equal to or greater than 1 MW.
• 3.2. These Guidelines do not apply to the following:
  • emergency combustion turbines;
  • combustion turbines used solely for purposes of research and development and field demonstration; and
  • combustion turbines under repair, those being tested during their commissioning period or during verification of repairs.
• 3.3. Section 4 of these Guidelines does not apply to peaking combustion turbines with a power rating of less than 4 MW. However, the other sections of these Guidelines should still be met.

4. NO_x Emission Limits

• 4.1. The performance of the combustion turbines should be determined using either one of the following methods:
  • i. the output-based method; or
  • ii. the concentration-based method.
• 4.2. The NO_x emission limits in tables 1 and 2 are a function of the turbine application and its power rating (expressed in MW). These limits do not apply during start-up periods, shut-down periods, periods of part-load operation or when the ambient temperature at the point of air intake is less than −18°C.
• 4.3. Output-based method
• Under the output-based method, limits are expressed as emission intensity (mass of NO_x per unit output of shaft or electrical energy). To conform with these Guidelines, an operator should meet the applicable emission limit mentioned in Table 1. The NO_x emission limits take into consideration the quantity of energy produced by the combustion turbine, calculated in gigajoules (GJ), as well as the emissions, calculated in grams (g) of NO_x.

B. Quantification of Production

1. The operator of the combustion turbine should install, maintain and operate a device to measure the mechanical output and, as the case may be, the gross electrical output of the combustion turbine during NO_x testing. The combined values from these devices should give the power (mechanical and/or electric) output of the unit.
2. The operator of the combustion turbine should install, maintain and operate a device to measure the heat output delivered by the combustion turbine operating in a cogeneration application during NO_x testing.

C. Compliance Determination: Continuous Emissions Monitoring System

1. A Continuous Emissions Monitoring System (CEMS) may be used to measure NO_x emissions in lieu of stack testing.
2. A CEMS should be used on non-peaking electricity generating combustion turbines with a power rating greater than 25 MW.
3. The CEMS should meet the specifications for design, installation, certification and quality assurance/quality control (QA/QC) set out in the method published by Environment and Climate Change Canada entitled Protocols and Performance Specifications for Continuous Monitoring of Gaseous Emissions from Thermal Power Generation (EPS 1/PG/7) or the method published by Alberta Environmental Protection entitled Continuous Emission Monitoring System (CEMS) Code.

As an alternative, a Predictive Emission Monitoring System (PEMS) is an acceptable equivalent to a CEMS if it meets the EPA method entitled Method 16 — Specifications and Test Procedures for Predictive Emission Monitoring Systems in Stationary Sources, set out in the Title 40, Chapter I, Subchapter C, Part 60 of the CFR.
5. NO_x emissions information (e.g. data averages) should be collected for the purpose of these Guidelines when the turbine operates at the conditions outlined in Part D.
6. For the output-based method, the operator should also, during the period of data collection
   • a. Install, maintain and operate a device to measure heat input so that NO_x emissions information can be converted to mass per hour emission rate using equation B-1 in Appendix B of the method published by Environment and Climate Change Canada entitled Protocols and Performance Specifications for Continuous Monitoring of Gaseous Emissions from Thermal Power Generation (EPS 1/PG/7). An average rate should be determined.
   • b. Install, maintain and operate a device to continuously measure the mechanical and, as the case may be, the gross electrical output of the unit; determine the combined mechanical and electric output of the unit; calculate the average hourly output.
   • c. Measure the heat output delivered from the combustion turbine operating in a cogeneration application during an emissions testing period; calculate the average hourly output.
   • d. Verify compliance with the applicable output-based limit by calculating the emission rate using equations (3) and (4) in Part A.

D. Operating Conditions

1. The measurement of NO_x emissions should be done under normal operating conditions as follows:
   • a. All emission performance tests should be conducted when the combustion turbine is operated at a load level that is within 70% to 100% of its power rating.
   • b. Despite paragraph (a), testing may be conducted at the highest achievable load, if it is not practically possible to operate the combustion turbine at a load equal to or greater than 70% of its power rating.
   • c. Testing should reflect typical operation conditions and fuel characteristics. Testing under atypical or artificial conditions will not satisfy the requirements of these guidelines.
   • d. Testing should be done at ambient temperatures greater than or equal to −18°C.
2. When more than one combustion turbine is venting through a common stack, the emission samples taken from that stack should take place with one combustion turbine operating at a time.
   
   However, if more than one combustion turbine shares air emission control equipment, one emission sample can be taken for all turbines when taken downstream of the air emission control equipment.

E. Accuracy of Data

1. Measurement devices required for these Guidelines should be calibrated at the most frequent of the following:
   • a. at least once every three calendar years;
   • b. at the frequency recommended by the manufacturer; or
   • c. as specified in the test methods for the devices.
2. Each measurement device should enable measurements to be made within an accuracy of ± 5%.

Summary of the draft screening assessment of the Poly(bios) Group

Pursuant to section 68 or 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of five substances referred to collectively as the Poly(bios) Group. Substances in this group were identified as priorities for assessment, as they met categorization criteria under subsection 73(1) of CEPA or were considered a priority based on other human health concerns. The Chemical Abstracts Service Registry Numbers (CAS RN (see footnote 4)) of the substances, their Domestic Substances List names and their acronyms are listed in the table below.

Substances in the Poly(bios) Group

CAS RN (see footnote 5)	Domestic Substances List name	Acronym
1401-55-4 (see note a)	Tannins	—
1415-93-6 (see note b)	Humic acids	—
65996-62-5	Starch, oxidized	—
56780-58-6 (see note c)	Starch, 2-hydroxy-3-(trimethylammonio)propyl ether, chloride	SEGAC
65497-29-2 (see note d)	Guar gum, 2-hydroxy-3-(trimethylammonio)propyl ether, chloride	GEGAC

• Note a: This substance was not identified under subsection 73(1) of CEPA, but was included in this assessment as it was considered a priority based on other human health concerns.
• Note b: This substance was not identified under subsection 73(1) of CEPA, but was included in this assessment as it was considered a priority based on other human health concerns.
• Note c: This substance was not identified under subsection 73(1) of CEPA, but was included in this assessment as it was considered a priority based on other human health concerns.
• Note d: This substance was not identified under subsection 73(1) of CEPA, but was included in this assessment as it was considered a priority based on other human health concerns.

These five substances were previously evaluated under the second phase of polymer rapid screening, which identified tannins, humic acid and oxidized starch as having low potential to cause ecological harm, and SEGAC and GEGAC as having low potential to cause harm to human health. However, they were identified as requiring further assessment for potential human health or ecological risks on the basis of structural alerts and/or uses associated with significant consumer exposure. The present assessment further elaborates on the potential for tannins, humic acid and oxidized starch to cause harm to human health, and for SEGAC and GEGAC to cause ecological harm, in order to reach an overall conclusion under section 64 of CEPA as to whether or not they pose a risk to the environment or human health.

Tannins occur naturally in the environment. In Canada, they are reported to be used in the food, pharmaceutical, cosmetic, fabric and textile industries. It has been reported that volumes between 100 and 1 000 kg of tannic acid (the most commonly used tannin) were either imported or manufactured in Canada in 2014. Tannins do not contain any reactive functional groups or other structural features associated with human health concerns. The toxicological information available indicates that it has a low hazard profile for human health. Tannins are naturally occurring in a number of botanical sources, and tannic acid can be used as a food additive. Therefore, direct exposure is expected; however, indirect exposure through drinking water is negligible.

Humic acid occurs naturally in the environment. In Canada, it is reported to be used in cosmetics and natural health products. Import volumes of up to 100 000 kg of humic acid have been reported for the year 2014. Humic acid does not contain any reactive functional groups or other structural features associated with human health concerns. The toxicological information available indicates that it has a low hazard profile for human health. Humic substances are naturally occurring in the environment; however, both direct and indirect exposure to humic acid is expected to be negligible.

Oxidized starch does not occur naturally in the environment. In Canada, it is reported to be used in the paper and textile industries. It has been reported that greater than 10 million kilograms of oxidized starch were either imported or manufactured in Canada in 2014. The reactive aldehyde groups present in oxidized starch are found to be at very low amounts and do not present a human health hazard. No other toxicological concerns were identified; therefore, oxidized starch has a low hazard profile for human health. Oxidized starch is used as a food ingredient and, therefore, direct exposure from the diet is expected.

SEGAC is a cationic modified starch compound that does not occur naturally in the environment. According to available information, SEGAC is used in the pulp and paper industries, and between 100 000 and 1 000 000 kg were imported into Canada in 2014. Based on the use pattern and exposure pattern, SEGAC is not expected to pose a risk to the environment.

GEGAC is manufactured by modifying guar gum with cationic functionality. It does not occur naturally in the environment. Up to 100 000 kg of GEGAC were imported into Canada in 2014 and reported to be used in personal care products. Considering the use patterns and hazard profile, GEGAC is not expected to pose a risk to the environment.

Considering all available lines of evidence presented in this assessment, there is low risk of harm to organisms and the broader integrity of the environment from tannins, humic acid, oxidized starch, SEGAC, and GEGAC. It is proposed to conclude that tannins, humic acid, oxidized starch, SEGAC, and GEGAC do not meet the criteria under paragraph 64(a) or (b) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or their biological diversity or that constitute or may constitute a danger to the environment on which life depends.

Based on the information presented in this screening assessment, it is proposed to conclude that tannins, humic acid, oxidized starch, SEGAC, and GEGAC do not meet the criteria under paragraph 64(c) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Proposed conclusion

It is proposed to conclude that tannins, humic acid, oxidized starch, SEGAC, and GEGAC do not meet any of the criteria set out in section 64 of CEPA.

The draft screening assessment for these substances is available on the Canada.ca (Chemical Substances) website (www.canada.ca/en/health-canada/services/chemical-substances.html).

Summary of the final screening assessment of 2-MBS

Pursuant to section 68 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of benzenesulfonamide, 2-methyl-, hereinafter referred to as 2-MBS. The Chemical Abstracts Service Registry Number (CAS RN) for 2-MBS is 88-19-7. This substance is among those substances identified as priorities for assessment based on human health concerns.

2-MBS does not occur naturally in the environment. In 2011, there were no reports of manufacture above the reporting threshold of 100 kg for 2-MBS; between 1 000 and 10 000 kg of 2-MBS were imported into Canada. It is used primarily as an intermediate for fluorescent pigments and plasticizer resins and as a plasticizer for hot-melt adhesives. 2-MBS is used in cosmetics as an ingredient in nail polish and may be formed in small amounts during the manufacture of the food additive saccharin (according to regulations specific to food-grade specifications for additives, saccharin can contain no more than 10 parts per million of 2-MBS as an impurity).

The ecological risk of 2-MBS was characterized using the ecological risk classification of organic substances (ERC). The ERC is a risk-based approach that employs multiple metrics for both hazard and exposure based on weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles based principally on metrics regarding mode of toxic action, chemical reactivity, food web–derived internal toxicity thresholds, bioavailability, and chemical and biological activity are established. Metrics considered in the exposure profiles include potential emission rate, overall persistence, and long-range transport potential. A risk matrix is used to assign a low, moderate or high level of potential concern for substances based on their hazard and exposure profiles. The ERC identified 2-MBS as having low potential to cause ecological harm.

Considering all available lines of evidence presented in this screening assessment, there is a low risk of harm to organisms and the broader integrity of the environment from 2-MBS. It is concluded that 2-MBS does not meet the criteria under paragraph 64(a) or (b) of CEPA, as it is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity or that constitute or may constitute a danger to the environment on which life depends.

For the general population of Canada, the potential exposure to 2-MBS was estimated as a total daily intake from environmental media (i.e. drinking water, dust and food). As well, exposure from use of nail polish containing 2-MBS was characterized.

The critical health effects were developmental effects, as well as effects on the liver and kidneys. Margins of exposure comparing effect levels for the critical health effects and the estimated exposures of the general population were considered adequate to address uncertainties in the health effects and exposure databases for 2-MBS.

Based on the information presented in this screening assessment, it is concluded that 2-MBS does not meet the criteria under paragraph 64(c) of CEPA, as it is not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Conclusion

Therefore, it is concluded that 2-MBS does not meet any of the criteria set out in section 64 of CEPA.

The final screening assessment for this substance is available on the Canada.ca (Chemical Substances) website (https://www.canada.ca/en/health-canada/services/chemical-substances.html).
