# FMC-Fairfield Evaluation Summary

D FMC-Fairfield is located in one of the least populated areas in Baltimore City. D Nearby sites within 20-km radius of FMC-Fairfield should be sufficient to capture population exposure. D PM Fine monitoring network is well-represented if not over-crowded in Baltimore Metro.

• CFR requires 3 FRM sites for a MSA > 

## 1 Million People. • MDE has deployed 9 FRM sites- (including FMC-Fairfield) within the Baltimore MSA. • There are 6 other FRM monitors within 20-km radius of FMC-Fairfield. 

# D Preliminary data for 2007 indicates that the FMC-Fairfield attains the annual PM Fine standard and violates the 24-hour PM Fine standard. D Preliminary data for 2007 indicates that the Southeast Police Station is the lead-monitor in the Baltimore MSA not the FMC-Fairfield site. 

# Shutting down FMC-Fairfield air monitoring site due to the closure of the FMC facility won't affect MOE's ability to measure population exposure to PM Fine.
