Region 7 States Air Quality Monitoring Plans - Missouri

Iowa, Kansas, Missouri, and Nebraska; Annual Monitoring Network Plans, Five-Year Monitoring Network Assessments, and approval documentation. Each year, states are required to submit an annual monitoring network plan to EPA. The network plans provide for the creation and maintenance of monitoring stations, in accordance with EPA monitoring requirements specified in 40 CFR (Code of Federal Regulations) Part 58.  For Five Year Monitoring Network Assessments, as stated at 40 CFR (Code of Federal Regulations) Part 58, each state is required to perform and submit to EPA an assessment of its air quality monitoring network every five years. At a minimum, this “five-year assessment” is meant to determine: if the existing network meets the monitoring objectives defined in Appendix D of 40 CFR Part 58; whether new sites are needed; whether existing sites are no longer needed and can be terminated; and whether new technologies are appropriate for incorporation into the ambient air monitoring network. For PM2.5 (particulate < 2.5 micrometers), the assessment also must identify needed changes to population-oriented sites. The first five-year assessment was due to EPA by July 1, 2010, and each assessment thereafter will be due in five-year increments.
