CCO CCO Environmental Regulations & Air Quality 1 — Questions and Answers
Question 1: Which federal agency primarily regulates air emissions from crematories in the United States?
- EPA (Environmental Protection Agency) (Correct answer)
- OSHA (Occupational Safety and Health Administration)
- FDA (Food and Drug Administration)
- CDC (Centers for Disease Control)
Correct answer: EPA (Environmental Protection Agency)
The EPA sets and enforces air quality standards for crematory emissions under the Clean Air Act.
Question 2: What is the primary air pollutant of concern emitted from cremation retorts?
- Carbon monoxide
- Particulate matter (PM) (Correct answer)
- Nitrogen dioxide
- Sulfur dioxide
Correct answer: Particulate matter (PM)
Particulate matter is the primary regulated emission from cremation retorts and is subject to EPA and state standards.
Question 3: Which type of emission control device is most commonly used on cremation retorts to reduce particulate emissions?
- Wet scrubber
- Electrostatic precipitator
- Afterburner/secondary combustion chamber (Correct answer)
- Catalytic converter
Correct answer: Afterburner/secondary combustion chamber
An afterburner (secondary combustion chamber) operates at high temperatures to combust particulates and gases before they exit the stack.
Question 4: Under the Clean Air Act, crematoriums may be subject to which type of operating permit if they exceed emission thresholds?
- Title V Operating Permit (Correct answer)
- NPDES Permit
- RCRA Permit
- TSCA Permit
Correct answer: Title V Operating Permit
Facilities exceeding major source thresholds under the Clean Air Act must obtain a Title V Operating Permit from their state agency.
Question 5: What temperature must the secondary combustion chamber maintain to meet EPA guidelines for cremation?
- 1000°F (538°C)
- 1400°F (760°C) (Correct answer)
- 1800°F (982°C)
- 2200°F (1204°C)
Correct answer: 1400°F (760°C)
EPA guidelines recommend the secondary chamber maintain at least 1400°F (760°C) to ensure complete combustion of gases and particles.
Question 6: Mercury emissions from dental amalgam during cremation are regulated because mercury is classified as a:
- Criteria air pollutant
- Hazardous air pollutant (HAP) (Correct answer)
- Greenhouse gas
- Volatile organic compound
Correct answer: Hazardous air pollutant (HAP)
Mercury is classified as a hazardous air pollutant (HAP) under the Clean Air Act, requiring special handling and emission controls.
