Introduction 

On November 12, 2008 the Environmental Protection Agency (EPA) issued final revisions to the 

National Ambient Air Quality Standards (NAAQS) for lead (Pb). EPA revised the level of the 

primary standard from 1.5 micrograms per cubic meter (μg/m3) to 0.15 μg/m3, measured as total 

suspended particulates (TSP), and revised the secondary standard to be identical in all respects to 

the primary standard. EPA also promulgated new monitoring requirements including new design 

requirements for the Pb NAAQS surveillance network. Monitoring is now required for all Pb 

sources (source oriented monitoring) that may contribute to violations of the Pb NAAQS and/or 

emit more than 1 ton/year of lead. Monitoring is also required in large urban areas for Pb as part 

of a non source-oriented surveillance network. According to 40 CFR Part 58 Appendix D, 

monitoring agencies are required to begin source-oriented monitoring by January 1st, 2010 and 

are required to identify Pb sources to be monitored and sampling locations in the annual network 

plan submitted by July 1st, 2009. 

Public Comments 

Pursuant to Federal regulations, this plan is to be made available for public inspection and 

comments for at least 30 days prior to submission to U.S. EPA. Hard copies of this document 

were made available on June 1, 2009 at the South Coast AQMD Public Information Desk in 

Diamond Bar, CA. The document was also posted to the public South Coast AQMD website at 

www.aqmd.gov on June 1, 2009, with links under the South Coast AQMD home page titled 

“Current Programs, Events and Topics.” Links to the document are also provided in the “Air 

Quality” area of the website. The draft document will also be made available to U.S. EPA 

during this period for review. 

Monitoring Objectives 

The primary objective for the Pb monitoring network is to provide data on the ambient Pb air 

concentrations in areas where there is the potential for violation of the NAAQS. Revisions to the 

primary and secondary NAAQS for Pb provide requisite protection of public health and welfare 

respectively. Modifications made to the existing network design requirements for the Pb 

surveillance monitoring network will help to achieve better understanding of ambient Pb air 

concentrations near Pb emission sources and to provide better information on exposure to Pb in 

large urban areas. 

Methodology 

EPA has elected to continue use of current Pb-TSP Federal Reference Method (FRM, 40 CFR 

part 50 Appendix G), sampler with no substantive changes. The current method is based on the 

use of a high volume TSP FRM to collect a particulate matter (PM) filter sample and the use of 

EPA-approved Pb analysis methods. Upon data submission, monitoring agencies must now 

report the average pressure and temperature during the twenty four hour sample period, and 

report Pb concentrations using actual flow, rather than standard flow. 

Monitoring Requirements 

New network design requirements specify that monitoring agencies conduct ambient air Pb 

monitoring near sources that have the potential to cause Pb concentrations in ambient air in 

excess of the new NAAQS (0.15 μg/m3

, 3-month average). Agencies are required to have at a 

minimum, one source-oriented State and Local Air Monitoring Station (SLAMS) site located at 
Air Quality Monitoring Network Plan – July 2009 

D-3 

the maximum expected Pb concentration in ambient air resulting from each Pb source that emits 

1.0 or more tons/year based on the latest EPA National Emissions Inventory (NEI) or other 

scientifically justifiable method or data. The monitoring location is to be determined based on 

the modeled the point of maximum impact, taking into consideration population exposure and 

logistical considerations. EPA requires at a minimum, one non source-oriented monitor in every 

Core Based Statistical Area (CBSA) with a population of 500,000 people or more with 15% 

collocation for all monitors. These monitors are to be placed in neighborhoods within urban 

areas impacted by re-entrained dust from roadways, closed industrial sources of Pb, or other 

fugitive dust sources of Pb. EPA is allowing monitoring agencies to stagger installation of newly 

required monitors over a two year period. Monitoring agencies are required to install and 

operate the required source-oriented monitors by January 1 2010. The non source monitors are 

required to be installed and operated by January 1 2011. The annual monitoring plan due July 1, 

2009 must describe the planned monitoring that will begin by January 1, 2010 and the plan due 

July 1, 2010 must describe the planned monitoring to take place January 1, 2011. The minimum 

sampling frequency for the monitoring network remains at the current 1-in-6 day sampling 

frequency. 

Background

South Coast AQMD currently collects TSP Pb measurements at 10 sites (with two sites 

collocated) as part of an ambient Pb network. This established network meets the EPA 

requirements for the non source-oriented monitoring network. The spatial distribution of these 

sites is shown in Figure 1. 

In 1990, U.S. EPA requested that the South Coast AQMD collect ambient air particulate Pb 

samples near several large Pb handling (battery recycling) sources. Long-term source oriented 

monitoring began in 1991. Quemetco RSR in the City of Industry exceeded the previous federal 

ambient particulate Pb standard of 1.5 μg/m3 during the second quarter of 1991. Lead 

monitoring ended at Martin Brass Foundry Inc. in the City of Torrance during 1993 when 

measurements were consistently below the ambient standard. Sampling also ended at Quenell 

Enterprises Inc. in the City of Commerce in 2006 when the monitoring site was redeveloped. 

The facility is now owned by Exide Inc, and has reported emissions of 0.03007 tons/yr. 

South Coast AQMD currently conducts source-oriented monitoring at three facilities. At Exide 

Inc. in the city of Vernon, Pb emissions are reported as 1.998 tons/yr and sampling is currently 

conducted at two sites identified as “Rehrig” and “ATSF”. The Rehrig location began sampling 

in November 2007 in response to a request from AQMD compliance staff. The Rehrig site 

began monitoring on a 1-in-6 day schedule, but sampling frequency at Rehrig and ATSF was 

changed to either 1-in-2 or 1-in-3 day between February and May 2008, and the Rehrig site 

began daily sampling in May 2008. The monthly averages at Rehrig for December 2007 through 

April 2008 exceeded 1.5 μg/m3

. The results of sampling near Exide are summarized in Table 1. 

Monthly averages at Rehrig continue to exceed the new Pb NAAQS of 0.15 μg/m3. 

At Quemetco in the City of Industry, monitoring emissions are reported as 0.321 tons/yr and 

sampling is currently conducted at one site identified as “Closet World”. This location monitors 

on a 1-in-6 day sampling schedule and no exceedances of the previous 1.5 μg/m3 Pb NAAQS 

have taken place since 1991. Monthly averages last exceeded the new standard of 0.15 μg/m3

 Pb 
Air Quality Monitoring Network Plan – July 2009 

D-4 

in 2005. In 2006, monthly averages ranged between 0.02 and 0.10 μg/m3

. Sampling did not take 

place in 2007 and most of 2008 due to the loss of access to our sampling location. 

At Trojan Battery in Santa Fe Springs monitoring emissions are reported as 0.0145 tons/yr and 

sampling is conducted at one site identified as “UDDH”. The UDDH site operates on a 1-in-6 

day sampling schedule and no exceedances of the 1.5 μg/m3 Pb NAAQS have taken place since 

2006. The highest monthly average since 2006 was 0.23 μg/m3 occurring in May 2007. Since 

September 2007, all monthly averages have been below the new Pb NAAQS of 0.15 μg/m3

. 

Pb Sources and Emissions

EPA National Emission Inventory data from 2005 reports that there are three sources of Pb in 

South Coast AQMD that emit more than 1.0 ton/year (Table 2). In contrast, the most recent data 

from South Coast AQMD annual emissions reports (2006-2007) shows only one source greater 

than 1.0 ton/year (Table 3). The Quenell Enterprises facility in the City of Commerce, now 

owned by Exide has emissions of 0.03007 tons/year and Quemetco RSR has reported emissions 

of 0.321312 tons/yr. Based on these recent emissions reports, Exide is the only non-aviation 

source currently emitting over 1.0 ton/year. The new monitoring guidance also requires general 

aviation sources to be monitored if Pb emissions exceed 1.0 ton/yr. General aviation aircraft use 

leaded aviation fuel and have been identified as a source of Pb emissions. The EPA Technical 

Support Document, “Lead Emissions from the Use of Leaded Aviation Gasoline in the United 

States” reports Pb emissions estimates for the general aviation Pb sources across the country. Of 

these sources, one is located within South Coast AQMD boundaries; the top five airports above 

1.0 tons/year are shown in Table 4. Estimates for airport emissions of Pb for Van Nuys Airport 

are given as 1.4 tons/year. Current plans are to find a suitable location on the grounds of Van 

Nuys Airport or adjacent property at which to monitor for Pb. The monitor will be sited as close 

as feasible to the blast fence where the majority of piston-driven aircraft begin their take-off. 

Talks are underway with airport management and surrounding businesses to secure a location, 

and monitoring is to begin before the end of 2009. The current and planned source-oriented Pb 

monitoring network site information is included in Table 5 and depicted in Figure 2. Even 

though Quemetco and Trojan Battery emit less than 1.0 ton/year Pb, and recent data does not 

suggest potential exceedances of the new Pb standard, AQMD will continue monitoring in the 

coming year to demonstrate compliance with the new Pb NAAQS at these sites. 

Rule 1420 Monitoring

On September 11, 1992 South Coast AQMD adopted Rule 1420 in order to reduce emissions of 

lead from non-vehicular sources. The rule applies to all persons who own or operate facilities 

that use or process Pb containing materials such as primary or secondary Pb smelters, foundries, 

lead-acid battery manufacturers, or recyclers and lead-oxide, brass and bronze producers. 

Requirements include a provision that all facilities that process more than 10 tons of lead per 

year must install, maintain, and operate ambient air quality monitoring equipment. Any facility 

that processes more than 2 tons per year, but less than or equal to 10 tons of Pb per year must 

determine ambient Pb concentrations by either monitoring or dispersion modeling. Air quality 

samples must be collected using approved equipment from a minimum of two sampling sites at 

or beyond the property line of the facility where maximum ground level Pb concentrations are 

indicated by air dispersion modeling calculations. Samples are to be collected for 24 hours 

consecutively for 30 days, and thereafter every 6th day. Continuous recording of wind speed and 
Air Quality Monitoring Network Plan – July 2009 

D-5 

direction is required during sampling periods using approved equipment. Samples are submitted 

to an approved laboratory for analysis. Results are reported to South Coast AQMD each 

calendar quarter and any exceedances are reported within 24 hours of the completed sample 

analysis. 

Results of Rule 1420 sampling conducted by Exide show two occasions between December 2007 

and May 2009 when monthly averages were greater than 1.5 μg/m3

 (Table 1). During January 

2009 the North (N) site recorded a monthly average of 1.55 μg/m3 and in March 2009 the 

monthly average was 2.08 μg/m3. 

Rule 1420 sampling conducted at Quemetco shows the highest monthly average value recorded 

between February 2007 and February 2009 was 0.76 μg/m3

 just inside the fence line. Monthly 

means of values taken on the property of Quemetco are given in Table 6. 

Since Rule 1420 monitors are operated by the facilities and are often located on facility property 

within the fence line, data collected may not meet the definition of “ambient” and siting may not 

conform to relevant EPA siting criteria. Therefore they are not designated as SLAMS sites at 

this time. However these sites will provide data to aid in the enforcement of regulations 

designed to meet the new Pb standard. 

Source-oriented Monitor Siting

Source-oriented micro-scale sites are to be located at the site of maximum ambient impact, 

taking into account population exposure and logistical considerations. In practice, this generally 

equates to monitoring at the fence line or beyond at a site that is as close as feasible to point of 

highest modeled concentrations. Modeling was completed for each of source-oriented locations 

indicating the expected location of maximum impact for Pb. Dispersion modeling for each 

facility was performed using AERMOD (version 07026) to determine the monthly lead 

concentrations. The AERMOD default regulatory option was used and building downwash was 

included. AERMAP was used to determine the terrain base elevations for each receptor and 

source and a hill height scale value for each receptor. AERSURFACE was used to determine the 

surface albedo and surface roughness. A Bowen ratio of 1.0 was used, instead of the 

AERSURFACE output value. This was done because the National Land Cover Data (NLCD) 92 

dataset does not include the recent land development projects that occurred within Southern 

California, which would result in a lower Bowen ratio. AERMET was used to develop the 

necessary meteorological data for each project using the meteorological data from the 

appropriate monitoring station and upper air sounding data collected at the Miramar Naval Air 

Station. A 100-meter by 100-meter receptor grid centered on the facility was used, as well as 

fenceline receptors placed using 25-meter intervals. All facility boundary, source parameters, and 

emission rates were obtained from the most recently submitted (Health Risk Assessment) HRA 

for each facility. 

Using the U.S. EPA’s post processor, the maximum 3-month rolling average lead concentration 

was calculated. The results are plotted in Figures 3, 4 and 5. 
Air Quality Monitoring Network Plan – July 2009 

D-6 

Exide

The most recent Health Risk Assessment (HRA) for Exide was prepared in June 2007 using the 

emission inventory for the 2005/2006 inventory year, which reports a total facility emission of 

1.16 tons of lead per year from 18 on-site emission points. The meteorological data from the 

Lynnwood monitoring station was used. The maximum ground-level lead concentration is 0.88 

μg/m3 and is shown in Figure 3 along with current monitoring locations. 

South Coast AQMD will continue to monitor at the Rehrig and ATSF locations. The current 

sampling schedule for Rehrig and ATSF are daily, and 1-in-3 respectively. These schedules may 

be changed over FY 2009-10 to 1-in-6 depending on compliance needs. South Coast AQMD 

may relocate the ATSF sampler in FY 2009-10 to a location closer to the facility where higher 

concentrations are expected. 

Quemetco

The most recent HRA for Quemetco was prepared in January 2009 based on source tests 

performed in November 2008. The HRA reports total facility emissions of 0.15 tons of lead per 

year from 10 on-site emission points. Although the facility includes an on-site meteorological 

station, the data collected at the station is not sufficient to use in AERMET. Therefore, the 

meteorological data from the La Habra monitoring station was used. The maximum ground-level 

lead concentration is 0.03 μg/m3

. Using the post processor, the concentrations are rounded off to 

two decimal places. Therefore the maximum lead concentration is not identified at a particular 

point as there are five receptor locations with the same maximum concentration. Instead, the 

maximum lead concentration is represented by an area bounded by the 0.03 μg/m3

 isopleth in 

Figure 4. 

South Coast AQMD will continue to monitor at the Closet World location downwind of 

Quemetco. The current sampling site is located within the maximum modeled isopleth and 

cannot be located closer to the fence line due to the proximity of a flood control channel. The 

Closet World location currently monitors on a 1-in-6 day schedule. 

Trojan Battery

Modeling for Trojan Battery was based on the emissions reported for the 2006/2007 inventory 

year, which reports a total facility emission of 0.04 tons of lead per year from one on-site 

emission point. The meteorological data from the Lynnwood monitoring station was used. Since 

no stack parameters were available, the default parameters for SCC 31306505, obtained from the 

US EPA, were used. The maximum ground-level lead concentration is 0.04 μg/m3

. Using the 

post processor, the concentrations are rounded off to two decimal places. Therefore the 

maximum lead concentration is not identified at a particular point as there are two receptor 

locations with the same maximum concentration. Instead, the maximum lead concentration is 

represented by an area bounded by the 0.03 μg/m3 isopleth in Figure 5. 

South Coast AQMD currently monitors for Pb adjacent to Trojan Battery at a site designated as 

UDDH. The sampling location is as close to the highest modeled concentration area as possible 

given logistical siting constraints. Sampling will continue to confirm that Pb levels continue to 

remain below the new Pb NAAQS of 0.15 μg/m3

. Since emissions from this facility are much

D-7 

lower than 1.0 ton/year, and two years of data show no exceedances, this site may be 

discontinued in FY2009-10. 

Pb Non Source Monitors

Non source-oriented monitors are located in urban areas to gather information on general 

population Pb exposure. One non source-oriented monitor is required in each CBSA with a 

population > 500,000 as determined by the most recent census data. South Coast AQMD 

currently operates a non source-oriented monitoring network of 10 locations with three 

collocated sites detailed in Table 7 and depicted in Figure 1. South Coast AQMD’s current Pb 

monitoring network exceeds the minimum required monitoring as part of the final revision to the 

NAAQS for Pb. Any redesign of this network will be addressed in the 2010 Annual Network 

Plan.
