MEMORANDUM 

To: Chuck French, U.S. Environmental Protection Agency, OAQPS 

From: Mike Burr and Donna Lazzari, ERG 

Date: April 2011 

Subject: Draft Summary of the Ambient Lead Monitoring Data near Secondary Lead 

Smelting Facilities 

EPA is currently conducting a Risk and Technology Review (RTR) for the Secondary 

Lead Smelting source category. As part of this process, ambient lead monitoring data is used as 

one of the indicators of the effectiveness of fugitive emissions controls at these facilities. This 

memorandum summarizes the available ambient lead monitoring data near secondary lead 

smelting facilities in the U.S. that was utilized as part of EPA’s RTR process for the Secondary 

Lead Smelting source category. This memorandum is organized as follows: 

1.0 Data Extraction 

2.0 Summary of Monitoring Stations 

3.0 Summary of Ambient Lead Data 

4.0 Ambient Lead Concentrations Based on Enclosure Category 

1.0 DATA EXTRACTION 

EPA’s repository of ambient air quality data, the Air Quality System (AQS), was utilized 

to search for available ambient lead monitoring data around secondary lead smelting facilities. 

Where available, the 3-month rolling average lead concentrations were extracted for the period 

of 2008-2010 at any available monitoring stations within three miles of each of the facilities. 

The 2008-2010 time frame was chosen to be consistent with modeling conducted as part of 

EPA’s risk and technology review (RTR) for the Secondary Lead Smelting source category. 

Three-month rolling average concentrations were extracted to be consistent with the averaging 

time for the National Ambient Air Quality Standards (NAAQS) for lead. 

2.0 SUMMARY OF MONITORING STATIONS 

Ambient lead monitoring stations are located near 12 of the 14 secondary lead smelting 

facilities; data near the Exide Technologies facilities in Baton Rouge, LA and Forest City, MO 

were not available. Table 1 presents a summary of the monitoring stations near each of the 

secondary lead smelting facilities.

3.0 Summary of Ambient Lead Data 

Table 2 presents a summary of all the ambient lead concentration data at each monitor 

near the secondary lead smelting facilities. Note that “N/A” indicates that data for the specific 

monitor is not available for the specified time period. Figure 1 displays the mean of all 3-month 

rolling averages across all monitors for each facility and Figure 2 displays the maximum 3-

month rolling average across all monitors for each facility. As shown in Table 2, at least one 

maximum 3-month rolling average lead concentration from 2008-2010 exceeds the NAAQS for 

lead of 0.15 μg/m3near 9 of the 12 facilities for which ambient monitoring data was available. 

All raw ambient data used in this summary is available in the docket for the proposed Secondary 

Lead Smelting NESHAP.
