Techniques

Chapter 1: Techniques

Technology-Based Standards:

• Best Available Control Technology (BACT): NSPS utilizes BACT as its primary principle, requiring new sources to adopt the most effective and advanced pollution control technologies available. This approach ensures that new facilities operate at the highest level of environmental responsibility, preventing the introduction of new pollution sources into the environment.
• Control Technologies: NSPS includes a wide array of control technologies, tailored to specific industries and pollutants. Some common examples include:
  • Scrubbers: Remove sulfur dioxide (SO2) and other acidic gases from emissions.
  • Electrostatic precipitators: Remove particulate matter from flue gas streams.
  • Catalytic converters: Reduce emissions of nitrogen oxides (NOx).
  • Carbon capture and storage (CCS): Sequesters CO2 emissions from large industrial sources.
  • Selective catalytic reduction (SCR): Reduces NOx emissions by converting them into nitrogen gas.
  • Combustion optimization: Improves fuel efficiency and minimizes pollutant formation.

Monitoring and Enforcement:

• Continuous Emission Monitoring Systems (CEMS): NSPS mandates the use of CEMS for regulated pollutants. These systems provide real-time data on emission levels, facilitating compliance monitoring and rapid response to potential exceedances.
• Performance Testing: New sources undergo periodic performance tests to verify compliance with established emission limits. These tests assess the effectiveness of installed control technologies and ensure their proper operation.
• Enforcement and Penalties: The Environmental Protection Agency (EPA) enforces NSPS regulations through inspections, audits, and potential penalties for non-compliance. This enforcement mechanism ensures that industries adhere to the established standards and protect public health.

Ongoing Research and Development:

• Evolving Technologies: NSPS encourages ongoing research and development in pollution control technologies. As new and more efficient solutions emerge, the standards are updated to incorporate these advances.
• Technology Transfer: Sharing information and best practices among industry and research institutions helps accelerate the adoption of innovative technologies, leading to continuous improvements in air quality.

Chapter 2: Models

Emission Estimation Models:

• Estimating Emission Limits: EPA uses a variety of emission estimation models to determine appropriate NSPS emission limits for specific industries and pollutants. These models consider factors like source size, process operations, and available control technologies.
• AIRMOD and AERMOD: Widely used models to simulate atmospheric dispersion and predict pollutant concentrations downwind from stationary sources.
• Pollutant-Specific Models: Specialized models focus on predicting emissions and concentrations of specific pollutants like mercury, lead, and volatile organic compounds (VOCs).

Cost-Benefit Analysis:

• Evaluating Control Measures: NSPS considers the costs and benefits of implementing various control technologies. This approach balances the economic impact on industry with the public health benefits of improved air quality.
• Economic Modeling: Cost-benefit analyses incorporate economic models to estimate the economic impacts of regulations on industry and the wider economy.
• Health Benefits Assessment: These analyses also evaluate the health benefits of reduced air pollution, considering factors like reduced mortality, hospital admissions, and lost workdays.

Modeling Air Quality:

• Modeling Air Quality Impacts: NSPS utilizes air quality models to assess the effectiveness of regulations in improving air quality. These models simulate the transport, dispersion, and chemical transformation of pollutants in the atmosphere.
• Predicting Air Quality Trends: Modeling allows for projecting future air quality conditions based on various scenarios, including new sources, changes in emissions, and evolving meteorology.
