Understanding the Differences Between Network Plans and Assessments in Air Quality Management

This guide explores the distinctions between a Network Plan and a Network Assessment within the context of air quality management. A Network Plan is an annual requirement that tracks expected changes, while a Network Assessment is conducted every five years for a comprehensive evaluation of air monitoring networks and objectives. The first assessment was due on July 1, 2010, in accordance with EPA regulations. Key steps include preparing a regional description and utilizing GIS and various statistical tools for data analysis.

  1. GIS for Network Review

  2. What is the Difference Between a Network Plan and a Network Assessment? • Network Plan - Not a new requirement [40 CFR 58.10(a)] • Due every year • Simple accounting of changes expected for that year • • Network Assessment – • Once every 5 years • Detailed evaluation of networks and objectives

  3. Requirements: • Required by new monitoring rule [40 CFR Part 58.10(d)] • Once every 5 years • First assessment due July 1, 2010 • EPA guidance document http://www.epa.gov/ttnamti1/files/ambient/pm25/datamang/network-assessment- guidance.pdf

  4. Network Assessment Step 1: Prepare a Regional Description • Topography • •Climate • •Population • •Demographic trends • •Major emissions sources • •Current air quality conditions

  5. Additional Steps: Perform situational analyses • demographic shifts, • density or sparseness of existing networks, • New findings on health impacts • Political factors

  6. Resources • GIS • Simple displays can be made using GoogleEarth or Google Maps. • • Statistical software and database packages allow you to organize, manipulate, create, analyze, and display data. These packages include Microsoft Excel and Access, and tools from ITEP/TAMS

  7. Data Analysis Tools from TAMS Center:

  8. Resources • EPA AirDataoffers yearly summaries of U.S. air pollution data extracted from EPA's air pollution databases. Includes emissions and ambient monitoring. • • EPA AIRNow-Tech offers AIRNowobservational data. Navigator tool is a customizable, air quality GIS tool that allows you to display site information with multiple geographic, pollutant, and meteorological features. • Data tool allows you to create personalized site lists, access predefined queries, and download AIRNow observational data.
