CFR Navigator for Ambient Air Monitoring Programs: An Overview

CFR Navigator for Ambient Air Monitoring Programs is designed to assist the State of Montana's ambient air monitoring program with detailed inquiries about the Code of Federal Regulations (CFR), particularly focusing on parts that are pivotal to ambient air quality monitoring and management. This GPT is tailored to aid Air Monitoring Coordinators by providing precise interpretations and guidance on compliance with the regulatory texts of the CFR, particularly 40 CFR Parts 50 and 58, which cover the National Ambient Air Quality Standards (NAAQS) and Ambient Air Quality Surveillance respectively. A practical scenario illustrating its function could involve a query about the correct methodology for PM2.5 sampling as stipulated in 40 CFR Part 50. The CFR Navigator would then provide a detailed explanation of the CFR requirements for PM2.5 sampling, possibly referencing the method outlined in Appendix L to Part 50 and how it applies to the State's air monitoring efforts.

Key Functions and Use Cases

  • Regulatory Interpretation

    Example Example

    Interpreting the requirements for air quality index reporting under 40 CFR Part 58, Subpart G.

    Example Scenario

    A state air monitoring coordinator is unsure about the requirements for public reporting of air quality data, including the Air Quality Index (AQI). CFR Navigator provides a detailed interpretation of §58.50, outlining how states must report AQI to the public, emphasizing the necessity for daily reports in metropolitan statistical areas with populations exceeding 350,000.

  • Compliance Guidance

    Example Example

    Guidance on setting up a near-road monitoring station for NO2 as required by 40 CFR Part 58, Appendix D.

    Example Scenario

    Montana plans to expand its air monitoring network by adding a near-road NO2 monitoring station. The CFR Navigator outlines the procedural requirements, site selection criteria, and quality assurance requirements based on Appendix D to Part 58, ensuring the state's plan meets federal guidelines and contributes effectively to the national ambient air monitoring network.

  • Quality Assurance Project Plan (QAPP) Analysis

    Example Example

    Analyzing Montana's QAPP in the context of the requirements laid out in 40 CFR Part 58, Appendix A.

    Example Scenario

    When the State of Montana updates its QAPP, CFR Navigator examines the plan to ensure it aligns with the quality assurance requirements specified in Appendix A to Part 58. It checks for completeness, including QA procedures for monitor operation, data handling, and the process for ensuring data reliability and accuracy for regulatory decisions.

Common Questions about CFR Navigator for Ambient Air Monitoring Programs

  • How can I determine if a monitoring site meets the criteria for comparison to the PM2.5 NAAQS?

    To determine if a monitoring site meets the criteria for comparison to the PM2.5 NAAQS, refer to the specifications in 40 CFR 58.30. Sites representative of area-wide air quality are eligible for comparison to the annual PM2.5 NAAQS, while sites reflecting unique micro-scale or localized impacts may only be compared to the 24-hour PM2.5 NAAQS.

  • What are the requirements for operating Special Purpose Monitors (SPMs) under CFR Part 58?

    Operating Special Purpose Monitors (SPMs) must adhere to the quality assurance and data reporting requirements detailed in 40 CFR 58.20. SPMs must be included in the annual monitoring network plan, meet criteria in Appendix A, and data collected using FRM, FEM, or ARM must be submitted to AQS, following the specifications in Appendix A for comparability and reporting.

  • How often must ambient air quality data be reported and certified?

    Ambient air quality data must be reported quarterly and certified annually, as specified in 40 CFR 58.16 and 58.15, respectively. The certification letter, affirming the accuracy and completeness of data to the best knowledge of the certifying official, is due by May 1st each year.

  • What steps should be taken to assess the quality of a monitoring network?

    A monitoring network's quality assessment involves submitting an annual monitoring network plan and conducting a periodic network assessment every five years, as required by 40 CFR 58.10. These documents should outline the network's compliance with monitoring objectives, any needed modifications, and the maintenance of an air quality surveillance system.

  • What criteria must be met for discontinuing a SLAMS monitor?

    To discontinue a State or Local Air Monitoring Station (SLAMS) monitor, certain criteria outlined in 40 CFR 58.14 must be met, such as demonstrating attainment during the previous five years and a low probability of exceeding NAAQS thresholds, or by showing that it measures lower concentrations than another monitor in the same area, among other criteria.
