Comments on 2010 ADEQ Network Plan 

Please update next year’s annual network plan to reflect the following comments: 

• The monitor/site tables for Pb, PM10, and PM2.5 on pages 66-70 in should include 

the specific dates for the last two semi-annual flow audits should be included in 

each applicable site report. 

• The monitor/site tables for PM2.5 should include the date of the last PEP audit 

performed. 

• The monitor/site tables for the gaseous pollutant on pages 62-65 should contain 

information pertaining to the residence times, probe material used, and the date of 

the last NPAP audit performed. 

• The Hayden Old Jail monitor/site table on page 65 states that the SO2 monitor 

operating at this site is part of the SLAMS network, while the site is also 

described as a part of the Source Compliance Monitoring Network in Table 4.7-1 

on page 25. Please clarify the characterization of the SO2 monitoring at this site. 

• The monitoring sites in Miami are characterized as part of ADEQ’s SIP sites and 

the Source Compliance Monitoring Network. Please clarify the characterization of 

monitoring at these sites. Also, Appendix A and D should include information 

pertaining these sites. 

• Section 4.0 should include a section describing the required Pb monitoring 

requirements. For example, Pb monitoring at Globe Highway should not be 

considered part of the Source Compliance Monitoring Network (Table 4.7-1) 

since Pb monitoring at this location is required by the CFR not a PSD permit 

requirement. This section should also describe the Pb monitoring location recently 

established in Miami, AZ.
