AERSCREEN is a screening-level air quality model developed by the U.S. Environmental Protection Agency (EPA) for evaluating air pollutant concentrations from single sources. It is designed to provide conservative estimates of maximum ground-level concentrations, making it an essential tool for regulatory compliance and initial air quality assessments.

Key Features

Simplified Modeling Approach AERSCREEN offers a streamlined method for air dispersion modeling.

• Uses worst-case meteorological conditions
• Produces maximum 1-hour ground level concentrations

Regulatory Compliance Ensures adherence to EPA guidelines for air quality assessments.

• Approved for use in regulatory applications
• Generates conservative estimates for screening purposes

User-Friendly Interface Designed for ease of use by environmental professionals.

• Intuitive input screens
• Clear presentation of results

Benefits

Time and Cost Efficiency AERSCREEN provides rapid preliminary assessments.

• Reduces the need for complex modeling in initial stages
• Allows for quick decision-making on further analysis requirements

Versatility Applicable to a wide range of source types and scenarios.

• Suitable for point, area, and volume sources
• Handles various terrain types and building downwash effects

Regulatory Acceptance Widely recognized and accepted by regulatory agencies.

• Facilitates smoother permitting processes
• Provides a solid foundation for more detailed modeling if needed
