Introduction

The South Carolina Department of Health and 

Environmental Control (DHEC) or its 

predecessors have operated an air quality 

monitoring network in South Carolina since 

1959. Since that time, the network has 

continually evolved to meet the requirements 

and needs of DHEC’s Air Program and to 

comply with federal requirements. In 2012 the 

network will comprise of 111 monitors and 

samplers at 35 sites.

In October, 2006, the United States 

Environmental Protection Agency (EPA) 

published revisions to the ambient monitoring 

regulations (71 FR 61236, October 17, 2006) 

requiring quality assurance (QA), monitor 

designations, minimum requirements for both 

number and distribution of monitors among 

metropolitan statistical areas (MSAs) and probe 

siting changes. The regulation also included the 

requirement for an annual monitoring network 

plan and periodic network assessments.

Monitor designations include the State and 

Local Air Monitoring Station (SLAMS), special 

purpose monitoring (SPM) and the National 

Core Monitoring Network (NCore). The 

SLAMS air monitoring network is specific for 

the criteria pollutants, those pollutants for which 

National Ambient Air Quality Standards 

(NAAQS) have been established. In addition to 

a SLAMS network, the air monitoring network 

includes SPM for air toxics, particulate, 

mercury, criteria pollutants, precipitation and 

meteorology. 

This plan covers the eighteen month period from 

July 1, 2011 through December 31, 2012. This 

period includes a 6 month implementation 

period during which sites indicated as ‘New’ 

will be identified, secured and prepared for the 

installation of monitoring equipment. It is 

expected that any monitoring indicated as ‘New’ 

or ‘To be established’ will be installed, 

calibrated and operating in 2011 with the 

exception of some ozone monitors which may 

begin operation at the start of the South Carolina 

Ozone Monitoring Season (April-October). 

Stakeholder groups have committed to assist in 

identifying and securing access to suitable 

locations. These efforts will continue in this and 

in subsequent monitoring plans as DHEC 

continues to identify new monitoring needs. 

The annual Network Description and Ambient 

Air Monitoring Plan , as required and described 

in 40 CFR Part 58.10, Annual Monitoring 

Network Plan and Periodic Network 

Assessment, must contain the following 

information for each monitoring station in the 

network: 

• The Air Quality System (AQS) site 

identification number for existing stations. 

• The location, including street address and 

geographical coordinates, for each 

monitoring station. 

• The sampling and analysis method used for 

each measured parameter.

• The operating schedule for each monitor. 

• Any proposal to remove or relocate a 

monitoring station within a period of 

eighteen months following the plan 

submittal.

• The monitoring objective and spatial scale 

of representativeness for each monitor. 

• The identification of any sites that are 

suitable for comparison against the PM2.5

NAAQS. 

• The MSA, Core-Based Statistical Area 

(CBSA), Combined Statistical Area (CSA) 

or other area represented by the monitor.

This document constitutes the South Carolina 

Air Monitoring Network Plan and is organized 

into two main parts: 

Network Summaries: Presenting the total 

number of sites and monitors for the State. Also 

included is a listing of all proposed changes to 

the current network. 

Air Monitoring Station Description: An outline 

of the designations, parameters, monitoring 

methods and the purpose for each monitor at the 

site.

The South Carolina Ambient Monitoring 

Network (Monitoring Network) will be reviewed 

annually. Planned changes will be described in 

this Network Description and Ambient Air 
v 

Monitoring Plan (and the annual Network 

Description and Ambient Air Monitoring Plan 

revisions) and provided for public review and 

comment prior to submission to the EPA Region 

4 Administrator.

2012 Network Description and Ambient Air 

Monitoring Plan: Public Participation 

Opportunities 

In anticipation of the need for an updated 

monitoring plan, heightened public interest and 

potential impact of the monitoring regulation 

changes, DHEC’s Air Program once again 

solicited involvement from both internal (to 

DHEC) and external workgroups. 

Individuals that have expressed interest in the 

development of the ambient air monitoring 

network were notified of the availability of the 

plan and were invited to provide comments. 

This group consists of representatives from the 

business, environmental and health 

communities. 

Other opportunities for public involvement 

include: 

• A webpage maintained for publication and 

access to draft and reference documents and 

announcements1

. 

• Availability of the proposed 2012 Network 

Description and Ambient Air Network

Monitoring Plan for public review and 

comment ran from June 2 to July 1, 2011.

All recorded participants who registered in 

the outreach and discussion activities were 

notified when the plan became available for 

review.

DHEC is committed to continuing the 

involvement and participation opportunities in 

the development of the annual revisions of the 

Network Description and Ambient Air Network

Monitoring Plan and the periodic assessments of 

the air quality surveillance system.

Network Operation

The primary responsibility for the operation of 

the South Carolina Ambient Air Monitoring 

Network is assigned to the Division of Air 

 

1

http://www.scdhec.gov/environment/baq/AmbientAi

rMonitoring/ 

Quality Analysis in the Bureau of 

Environmental Services (Division). The 

Division establishes, maintains and operates the 

sites and instruments that make up the network 

and performs the analysis of samples collected 

as part of routine monitoring or special projects. 

Data generated by the network for comparison to 

the NAAQS is verified to be accurate and 

reported by the Division and stored in the 

national AQS database. 

Criteria pollutant monitoring for the purpose of 

comparison to the NAAQS is performed using 

EPA designated Federal Reference Methods 

(FRM) or Federal Equivalent Methods (FEM) to 

ensure the precision and accuracy of the 

measurements across the air quality surveillance 

system.

Regular calibration and audits of the 

measurement systems are performed to verify 

that the instruments are operating correctly and 

data being collected is accurate. The QA 

activities supporting the Monitoring Network 

meet or exceed the QA requirements defined in 

40 CFR Part 58 Appendix A (Quality Assurance 

Requirements for SLAMS, SPMs and PSD Air 

Monitoring). 

Raw data is collected hourly from sites across 

the state and provided to internal data users 

(forecasters and data analysts) and to the 

AIRNow database for presentation to the public. 

Before the data is submitted to AQS it is verified 

to be accurate through review of the instrument 

Quality Control (QC) and QA performance 

documentation. 

Instrument QA/QC alone is not sufficient to 

assure monitoring data quality. For this reason, 

DHEC, in addition to periodic site assessments, 

has begun conducting additional visits of 

monitoring sites to enable comparison with 

applicable siting criteria. 

It is DHEC’s intent that all criteria pollutant 

monitors and samplers be sited and operated 

consistent with the requirements of 40 CFR Part 

58 and Appendices A (Quality Assurance), C 

(Methods), D (Network Design) and E (Probe 

Siting Criteria) and the data collected by these 

samplers and monitors is suitable for 

comparison to the NAAQS. DHEC further 
vi

intends to assure that the samplers and monitors 

comply with as many of the recommendations 

contained within the regulations and applicable 

guidance documents as is possible.

An element of the Quality System2 employed by 

the Division is periodic assessments of systems 

and monitor performance. As the primary QA 

organization for ambient air monitoring 

activities, the Division operates under the 

approved Environmental Quality Control 

Quality Assurance Management Plan, the 

Ambient Air Quality Monitoring Quality 

Assurance Project Plan and approved plans for 

specific projects. EPA Region 4 provides 

periodic Technical Systems Audits of sampling 

and analytical methods, network operation, data 

collection and reporting and QA activities at 

their discretion or at the request of DHEC’s Air 

Program. EPA Region 4 may conduct audits of 

any component of the operation of the network 

or quality management system. The Division 

also participates in the National Performance 

Audit Program (NPAP) and the Performance 

Evaluation Program (PEP) administered by EPA 

to provide independent audits of criteria 

pollutant monitoring and performance. 

 

2 The Quality System is the means by which DHEC 

implements the quality management process through 

the Quality Assurance Management Plan for SC 

DHEC, July, 2008.

Station Description Content

Specific siting information for each site and 

monitor is stored in the EPA’s AQS, the national 

ambient air database. The AQS Site Description 

includes the exact location of the site, local and 

regional population and description of the site 

location, monitor types and monitoring 

objectives. This site and monitor information is 

routinely updated whenever there is a change in 

site characteristics or pollutants monitored.

The AQS is used as the primary repository for all 

South Carolina ambient monitoring data 

including site descriptions. All ambient 

monitoring data is stored in AQS, including non 

NAAQS parameters, ambient toxics, total 

suspended particulate and supporting QA data. 

Station Description

The network station descriptions contained in this 

document include the following information:

Site Description

The header for each site includes: 

Site Name

The Core Based Statistical Areas (CBSA) as 

defined by the US Census. (November 2006).3

AQS Site ID: The unique site identification 

number used in AQS in the form: 

45-0cc-ssss 

Where: 

 45 is the federal identification code for SC, 

cc is the county identification code; and

ssss is the site identification code within the 

county. 

Location: Typically the street address of the site

where available.

County: County in which the site is located.

Coordinates: Listed in decimal degrees, Latitude 

(N) then Longitude (W) using WGS84 projection. 

Date Established: The date when each existing 

monitoring station was established is shown in 

the description. For new stations proposed in this 

 

3 The US Census Bureau periodically adjusts CBSA 

names and boundaries. This plan uses the latest 

available revision. 

plan, a date is provided when it is expected for 

the station to be in operation. Individual monitors 

at a site may have differing start and stop dates. 

Date of most recent Site Evaluation: Each 

monitoring station in the network is periodically 

visited to determine whether all required probe 

exposure criteria for monitors are met. If 

necessary, corrective action is scheduled to 

address deficiencies. If a monitoring site has not 

yet been evaluated, it will be denoted with the 

word “PENDING”. Auditors may visit sites to 

provide an additional, independent QA check on 

the site evaluations. When an additional 

independent check has been conducted, the date 

of the visit will be noted next to the date of the 

latest site evaluation and contained within 

parentheses. 

Monitor Details

In a table associated with each site, the 

parameters monitored at that site are listed along 

with descriptive information associated with that 

parameter. 

Parameter

Criteria (compounds for which a NAAQS has 

been established), non criteria and/or supporting 

parameters (primarily meteorological 

measurements) measured at the site are listed. 

Scale

Each monitor or sampler in the monitoring 

network is described in terms of the approximate 

physical dimensions of the air parcel nearest the 

monitoring station throughout which pollutant 

concentrations are expected to be reasonably 

similar. This is most often referred to as the Scale

of the monitor. Different pollutants monitored at 

the same location may represent different scales 

depending on the characteristics of the pollutant. 

Area dimensions or scales of representativeness 

used in the network description are: 

(a) Microscale

Air volumes associated with area dimensions 

ranging from several meters up to about 100 

meters.

(b) Middle scale
2 

Areas up to several city blocks in size with 

dimensions ranging from about 100 meters to 0.5 

kilometers.

(c) Neighborhood scale

Extended areas of a city that have relatively 

uniform land use with dimensions ranging from 

0.5 to 4.0 kilometers. 

(d) Urban scale

Citywide or equivalent rural areas with 

dimensions ranging from 4 to 50 kilometers. 

(e) Regional scale

Areas ranging from 50 to hundreds of kilometers 

in diameter.

The true representative area may best be 

described by an irregular shape of the 

approximate dimensions indicated above 

accounting for local sources and differing land 

use.

The representative scale of a monitor is closely 

associated with the objective of the monitoring. 

Objective

The ambient air monitoring network is designed 

to meet three primary objectives: 

Provide air pollution data to the public in a timely 

manner. Near real-time data is made available on 

the internet through AIRNow and Air Quality 

Index (AQI) reporting and forecasting in the 

major metropolitan areas. 

Support compliance with ambient air quality 

standards and emissions strategy development.

Monitors are operated to measure concentrations 

for comparison to NAAQS and to provide 

information to aid in the development of 

strategies to improve air quality.

Support air pollution research studies. Data from 

the monitoring network support greater 

understanding of the impacts and effects of 

ambient air pollution. 

Individual monitors within a monitoring network 

that support these basic objectives generally serve 

one or more of the following purposes:

• Determine highest concentrations of 

pollutants, 

• Determine representative concentrations in 

areas of high population density, 

• Determine impact on air quality of significant 

sources or source categories,

• Determine general background concentrations,

• Determine extent of regional pollutant 

transport; and

• Determine welfare-related impacts in more 

rural and remote areas (ex. visibility 

impairment and impacts to vegetation).

The design intent in siting stations is to correctly 

match the area represented by the sample of 

monitored air with the area dimensions most 

appropriate for the monitoring objective of the 

monitor. The relationship of appropriate scale to 

the six basic purposes are:

Monitoring Purpose Siting Scale

Highest concentration Micro, Middle, 

Neighborhood 

Population Neighborhood, 

Urban

Source impact Micro, Middle, 

Neighborhood 

General/background Neighborhood, 

Urban, Regional 

Regional transport Urban, Regional 

Welfare-related impacts Urban, Regional 

Monitor and sampler data is regularly reviewed to 

assure the assigned scale is correct and 

appropriate for the intended objective. 

Designation 

Required and long term criteria pollutant 

monitors described in the air quality monitoring 

network are designated SLAMS. 

SLAMS: EPA requirements for air quality 

surveillance systems provide for the 

establishment of a network of monitoring stations 

designated SLAMS that measure ambient 

concentrations of those pollutants for which 
3 

standards have been established. These stations 

must meet requirements that relate to four major 

areas: QA, monitoring methodology, sampling 

interval and siting of instruments and instrument 

probes. 

Monitoring at some locations meets DHEC’s Air 

Program needs beyond that necessary for 

compliance with minimum requirements. Special 

Purpose Monitors (SPM) are operated to meet 

specific DHEC Air Program needs and may be 

long term or part of special studies designed to 

answer specific questions.

SPM: Monitors in the air quality surveillance 

network not designated SLAMS are Special 

Purpose Monitors. Special Purpose Monitors 

support investigations addressing complaints, 

areas and pollutants of concern, network 

refinement, modeling verification and 

compliance. These monitors are committed to 

investigation and projects as described in the 

associated Quality Assurance Project Plan 

(QAPP). They may be located as separate 

monitoring stations or be included at existing 

monitoring locations. Monitoring data will be 

reported to AQS where possible. Siting and probe 

exposure will conform to all requirements for 

SLAMS monitors whenever possible. 

Both SLAMS and SPM data may be used in the 

reporting of an area’s Air Quality Index. 

Air Quality Index (AQI): The AQI is a method 

of reporting that converts concentration levels of 

pollution to a simple number scale of 0-500. 

Index reporting is required for all urban areas 

with a population exceeding 350,000. Intervals on 

the AQI scale are related to potential health 

effects of the daily measured concentration of the 

measured pollutants. All stations in a 

metropolitan area provide data for daily index 

reporting. Data collected from continuous 

monitors for Ozone and PM2.5 monitors is 

collected hourly and reported as AQI maps on 

EPA’s AIRNow website. A daily AQI is provided 

for the Greenville-Spartanburg, Columbia and 

Charleston-North Charleston areas. 

Probe Height

The monitor or sampler probe is the point where 

ambient air enters the analytical or sample 

collection system. Ideally, air would be sampled 

approximately at nose height, but due to 

operational, exposure and security considerations 

air may be sampled further from ground level. 

Proper probe height is specified in the monitoring 

regulations (typically between 2 and 15 meters) 

and is checked as part of the periodic site 

evaluations. 

Analysis Methods 

All sampling and analytical procedures used for 

comparison of ambient concentrations of criteria 

pollutants to the NAAQS will use designated 

Federal Reference (FRM) or Federal Equivalent 

(FEM) Methods. Where appropriate for specific 

monitoring objectives, well characterized nonequivalent methods may be used. 

• Particulate Matter ≤ 10 microns (PM10) 

PM10 samplers operated by DHEC are designated 

as either FRM or FEM samplers and are operated 

according to the requirements set forth in 40 CFR 

Part 50 and 40 CFR Part 58. Intermittent 

samplers collect a 24-hour sample no less than 

every sixth day on a quartz filter. The filter is 

conditioned and weighed before and after the 

sample run. The gain in weight in relation to the 

volume of air sampled is calculated in 

micrograms per cubic meter (μg/m3

). The quartz 

filters are equilibrated before each weighing for a 

minimum of 24 hours at a 20-23°C mean 

temperature and a 30-40 percent mean relative 

humidity. 

Continuous PM10 samplers provide 24-hour 

concentration measurements every day. During 

sampling, ambient air passes through an inlet 

designed to pass only particles smaller than 10 

microns in diameter. After exiting the inlet, the 

sample stream is sent through a mass transducer 

to determine instantaneous and total flow. 

Particulate in the sample stream passes through a 

Teflon-coated glass fiber filter. This filter is 

weighed every two seconds. The difference 

between the current filter weight and the previous 

weight gives the total mass of the collected 

particulate for that period. The mass 

concentration is computed by dividing the total 

mass gained by the flow rate. Data is stored 

locally on redundant data acquisition systems and 

recovered hourly by an automated central data 

acquisition system.
4 

• Particulate Matter ≤ 2.5 microns (PM2.5) 

All PM2.5 samplers operated by DHEC are 

designated FRM samplers. Manual samplers are 

operated per the requirements set forth in 40 CFR 

Part 50, Appendix L. Samples are collected on 

46.2 millimeter Polytetrafluoroethylene (PTFE) 

filters over a 24-hour sampling period. Air flow 

through the filter is maintained at 16.7 liters per 

minute. The flow rate must not vary more than 

+/-5 percent for five minutes over a 24-hour 

sample period at actual ambient temperature and 

pressure. Samples are retrieved within 96 hours 

of the end of the sample run and are kept cool 

(4°C or cooler) during transit to meet the thirtyday limit for final weighing.

The PTFE filters are equilibrated and weighed 

before and after the sample run for a minimum of 

24 hours at a controlled atmosphere of 20-23°C 

mean temperature and 30-40 percent mean 

relative humidity. Filters are used within thirty 

days of initial weighing. Filters must be reweighed within thirty days of the end of the 

sample run if kept at 4°C or cooler. The gain in 

weight in relation to the volume of air sampled is 

calculated in μg/m3

. 

Continuous PM2.5 monitors provide hourly 

measurements for AQI reporting but do not 

provide concentration data currently suitable for 

comparison to the NAAQS. During monitoring, 

ambient air passes through an inlet system 

designed to pass only particles smaller than 2.5 

microns in diameter. After exiting the inlet, the 

sample stream is sent through a mass transducer 

to determine instantaneous and total flow. 

Particulate in the sample stream passes through a 

Teflon-coated glass fiber filter. This filter is 

weighed every two seconds. The difference 

between the current filter weight and the previous 

weight gives the total mass of the collected 

particulate for that period. The mass 

concentration is computed by dividing the total 

mass gained by the flow rate. Data is stored 

locally on redundant data acquisition systems and 

recovered hourly by an automated central data 

acquisition system.

PM2.5 Speciation sampling and analysis

In addition to operating PM2.5 samplers that allow 

measurement of only PM2.5 mass concentration, 

DHEC also operates PM2.5 speciation samplers 

that collect samples that are analyzed to 

determine the chemical makeup of PM2.5. 

Samples are collected on a set of three cartridges 

over a 24-hour sampling period. The individual 

cartridges contain denuders and filters designed 

to efficiently capture the major components of 

PM2.5. 

After collection, the samples are shipped in ice 

chests to the EPA contract laboratory for analysis. 

At the laboratory the samples are analyzed using 

thermal optical analysis (for carbon), ion 

chromatography and x-ray fluorescence (for 

metals) to determine the presence and 

concentration of specific compounds. Sample 

results are stored in AQS.

• Sulfur Dioxide (SO2) 

Instruments used to continuously monitor sulfur 

dioxide concentrations in the atmosphere employ 

the FEM Ultraviolet (UV) fluorescence method. 

The continuous data output from the instrument is 

stored locally on redundant data acquisition 

systems and recovered hourly by an automated 

central data acquisition system.

Calibration of these instruments is done 

dynamically using EPA protocol gas mixtures 

containing a known concentration of sulfur 

dioxide in nitrogen. This gas is diluted to give 

varying known concentrations of sulfur dioxide. 

These known concentrations are supplied to the 

instrument, which is adjusted so that the 

instrument output corresponds with the specific 

concentrations. Calibration curves are prepared 

for each instrument and each measurement is 

automatically compared to this curve before entry 

into the data acquisition system. 

• Carbon Monoxide (CO)

Continuous monitoring for carbon monoxide is 

performed by use of the FRM non-dispersive 

infrared correlation method. Data is stored locally 

on redundant data acquisition systems and 

recovered hourly by the Division automated 

central data acquisition system.

Calibration of the instrument is done dynamically 

using EPA Protocol gas mixtures containing a 

known concentration of carbon monoxide in air. 

The gas is diluted to give varying known 
5 

concentrations of carbon monoxide. These known 

concentrations are supplied to the instrument, 

which is adjusted so that the instrument output 

corresponds with the specific concentrations. 

Calibration curves are prepared for each

instrument and each measurement is 

automatically compared to this curve before entry 

into the data acquisition system. 

• Ozone (O3)

Ozone is monitored using the FEM Ultraviolet 

(UV) photometry method. The continuous data 

output from the instrument is stored locally on 

redundant data acquisition systems and recovered 

hourly by the Division automated central data 

acquisition system.

Monitors are routinely calibrated using portable 

ozone transfer standards. Calibration curves are 

prepared for each instrument and each 

measurement is automatically compared to this 

curve before entry into the data acquisition 

system.

• Nitrogen Dioxide (NO2)

The FRM chemiluminescence and UV methods 

are used in monitoring the nitrogen dioxide 

concentration in the ambient air. The continuous 

data output from the instrument is stored locally 

on redundant data acquisition systems and 

recovered hourly by an automated central data 

acquisition system.

Calibration of the instrument is done dynamically 

using EPA protocol gas mixtures containing a 

known concentration of nitric oxide in nitrogen. 

The gas is diluted to give varying known 

concentrations of nitric oxide. An ozone 

generator and converter are used to convert nitric 

oxide (NO) to nitrogen dioxide (NO2). These 

known concentrations are supplied to the 

instrument, which is adjusted so that the 

instrument output corresponds with the specific 

concentrations. Calibration curves are prepared 

for each instrument and each measurement is 

automatically compared to this curve before entry 

into the data acquisition system. 

• Lead

Lead concentrations are determined from the 

analysis of total suspended particulate collected 

using high volume particulate samplers as 

described in 40 CFR §50 Appendix G. Particulate 

samples are acid extracted to dissolve the metals. 

The lead content is determined using Flame 

Atomic Absorption or Inductively Coupled 

Plasma (ICP) spectrophotometry.

Sampling Frequency

Measurements of the parameters related to air 

quality are performed using sampling and 

continuous monitoring. Sampling frequency is the 

indicator of how often a measurement is made 

and reported. 

Sampling typically involves collection of a 

sample over a period (typically 24 hours, 

midnight to midnight) and delivery of the sample 

to the laboratory for preparation and analysis. 

Samples are collected every day (1:1), every third 

day (1:3), every sixth day (1:6) and for some 

projects, every twelfth day (1:12) depending on 

the data quality objectives necessary for the 

project. Results of the analysis are reported as 

averages for the period. The EPA publishes 1:3 

and 1:6 day sampling schedules used nationwide 

and by the Monitoring Network. 4

Monitoring typically uses on-site analyzers that 

continuously sample the air and measure the 

pollutant of interest. Results of the analysis are 

reported as hourly averages.

Changes for 2012

Any planned changes in parameters monitored, 

the configuration, or operations at the site 

planned for 2012 are described herein and 

summarized in the Summary of 2012 Network 

Changes. Unless otherwise indicated, changes at 

a site including the beginning of new monitoring 

activity will be effective January 1, 2012. Ozone 

monitoring for 2012 at new or special project 

sites may start at the beginning of the ozone 

monitoring season (April-October).

Required Monitoring SO2 – Population Weighted Emissions Index (PWEI) 

On June 22, 2010, the EPA finalized revisions to the SO2 NAAQS. As part of this rulemaking, the EPA 

set new minimum monitoring requirements for CBSA based on population and SO2 emissions. The

following table presents each CBSA’s population, SO2 emissions, calculated index and minimum 

monitoring requirements. The process for calculating the index can be found at the bottom of the table.

The PWEI is calculated using US Census population data and state emission inventory data at the CBSA level. The population 

for each CBSA (based on the most recent US Census or Census estimate) is multiplied by the CBSA total SO2 emissions 

(measured in tons using the latest National Emissions Inventory data). This product is divided by 1,000,000 to derive the index.

• CBSA with index greater than 1,000,000 will require 3 monitors.

• CBSA with index less than 1,000,000 but greater than 100,000 will require 2 monitors.

• CBSA with index less than 100,000 but greater than 5,000 will require 1 monitor.

• CBSA with index less than 5,000 will require no monitors.

*Monitors may be operated in the non-South Carolina portion of the CBSA.

Required Monitoring for Lead Ambient Air – facilities with annual emissions greater than 

0.5 tons per year (tpy) 

On December 27, 2010, the EPA published revised minimum monitoring requirements for the Lead 

NAAQS. Any facility with annual lead emissions exceeding 0.5 tpy will be required to have a lead 

sampler. Based on the state-submitted 2010 National Emissions Inventory, there are no facilities in South 

Carolina with lead emissions greater than 0.5 tpy. 

On May 7, 2010, DHEC issued an air synthetic minor construction permit to Johnson Controls Battery 

Group for the Florence Recycling Center (Permit No. 1040-0129-CA). Under a settlement agreement5

with several petitioners, the Florence Recycling Center will support source-oriented ambient lead 

monitoring at several sites around the facility to be conducted by DHEC. Additional details of the 

monitoring of this facility can be found in the Florence MSA section of this plan under the site name 

“Johnson Controls.”

Location: Round Mt. Fire Tower 

County: Oconee

Coordinates: +34.805261, -83.237700 

Date Established: August 1, 1983

Site Evaluation: The most recent site evaluation was conducted on February 18, 2005 (QA Check: 

March 18, 2008). 

The Long Creek monitoring site is located on Round Mountain 

in northwest Oconee County. The Long Creek site was 

established as part of the Southern Oxidant Study. It provides a 

unique vantage for monitoring the impacts of transported 

pollutants. Long Creek has continuous monitors for ozone, 

PM2.5, sulfur dioxide and precipitation. The sample inlets are 

11.0 meters from the nearest road. 

Due to the importance of measuring region-wide sulfur dioxide, 

PM2.5 and ozone concentrations, the unique location and 

collocated monitoring activity, DHEC has determined that 

current monitoring at this site should be continued. 

This site is part of the Greenville MSA Ozone study, initiated in 2008 and designed to investigate ozone 

concentration variability across the Upstate and provide information to help refine the monitoring 

network to better meet monitoring objectives. DHEC will evaluate data from all of the previously

The Cape Romain site is located in Charleston County at the 

Cape Romain National Wildlife Refuge (NWR) near Moores 

Landing. 

The Cape Romain NWR is a Class I area about 20 miles 

northeast of Charleston. The majority of the Refuge area is 

offshore extending from Bull Island 20 miles northeast to Cape 

Romain. The Refuge is bordered on the west by the Intracoastal 

Waterway. Inland are large tracts of forests with scattered 

residences. Several miles inland, a primary coastal route, US 

Highway 17, parallels the coast, with some development along 

the section of highway that is closest to the Refuge. 

The Cape Romain site has samplers for PM2.5 speciation and continuous monitors for carbon monoxide, 

sulfur dioxide, nitrogen dioxide, ozone, black carbon, meteorological parameters and PM2.5. The sample 

inlets are 18 meters from the nearest road.

The Cape Roman site is collocated with the Interagency Monitoring of Protected Visual Environments 

(IMPROVE) sampling site and nearby monitoring performed by other agencies includes precipitation 

chemistry and mercury deposition. The site has been used for multiple interagency and regional air 

monitoring projects.

Network Development

The Monitoring Network provides data to support an array of decisions ranging from development of 

emissions strategies to protect and improve air quality to the level of activity appropriate for individuals 

in sensitive populations. To support these varied data users, the network must provide both stable long 

term measures to document trends and rapid reporting of conditions to the public. In response to land use, 

population and urban areas growth, the network must be evaluated and adjusted to meet the changing 

conditions and needs. 

The Monitoring Network described in this plan continues to build upon a significant transition from the 

network that has evolved over the last thirty-five years. It reflects the successes in reducing ambient 

concentrations of Total Suspended Particulate, lead, carbon monoxide, nitrogen oxides and sulfur dioxide 

and the increasing concern about the impact of fine particles and ozone on public health and the 

environment. 

A series of studies are planned for the major urban areas to gain better understanding of the air quality 

and provide information to improve the monitoring network. In addition to the intensive studies that 

provide a detailed ‘snapshot,’ it is intended that SPM sites be established and monitored in rotation to 

provide regular checks and long term tracking of the trends in air quality in all areas of the state including 

smaller cities, towns and rural areas. The implementation of this long term strategy is contingent on 

sufficient federal funding and will be developed and evaluated as resources again become available. 

Project plans will be developed for the monitoring and data analysis activity to better define the scope of 

these strategies prior to implementation. These studies are long term evaluations DHEC has identified for 

several years and are important for evaluating and improving our knowledge of air quality in the State. 

Areas where long term strategies are being considered include:

• Columbia MSA Ozone Study - addition of supplementary SPM ozone sites to investigate 

variability and refine the monitoring network to meet objectives. 

• Columbia MSA Particulate Surveillance - rotation of SPM PM2.5 sites through areas with higher 

rates of growth and changes in land use to determine trends and understand spatial variability of 

concentrations (Parklane, Sandhill and potentially Lower Richland, Lexington and Chapin). 

• Aiken County portion of the Augusta-Richmond County MSA Ozone Study - addition of 

supplementary SPM ozone site to investigate proper size of the network appropriate to represent 

the MSA.

• Aiken County portion of the Augusta-Richmond County MSA Particulate Study – investigation 

of PM2.5 concentrations in North Augusta and Aiken along with existing rural data to determine 

population exposure and possible need for monitoring of mass or the components of particulate to 

assist in area air quality improvement efforts.

• York County Ozone Study - limited investigation of ozone population exposure, spatial 

variability and transport to supplement existing North and South Carolina monitoring. This study 

is necessary because of siting issues and lack of long term commitment at the current York CMS 

monitoring site.

Georgetown CMS

CSA/MSA: Myrtle Beach-Conway-Georgetown CSA 

AQS Site ID: 45-043-0006 

Location: 1369 Dock Street 

County: Georgetown

Coordinates: +33.362014, -79.394251 

Date Established: October 25, 1972 

Site Evaluation: The most recent site evaluation was conducted on April 2, 2007. 

The Georgetown CMS site is located in Georgetown County. 

Georgetown CMS is located in an industrial area dominated by 

point sources and is not intended to represent PM10

concentrations in populated areas. The sample inlets are 21 

meters from the nearest road.

The site is in very close proximity to several local sources (e.g., 

truck parking, material handling and road dust) and is not near 

inhabited buildings or locations where the general public can be 

expected to have access. The data collected at this location is 

intended for use by DHEC, local government and industry to 

enable quick response to the impacts of local activities to minimize emissions. While not representative of 

population exposure, the continued availability of the data is important to the efforts of DHEC and local 

stakeholders to protect air quality in nearby communities.

Previous monitoring in the local residential areas at the Maryville, Howard High and Winyah sites have 

confirmed this location is representative of no more than middle scale.

Changes for 2012: 

Access to the monitoring location was lost in early 2011 when the property owner developed the land. 

DHEC is currently working with the landowner to gain access on another piece of property nearby to 

establish a wind tower to maintain meteorological monitoring in the area.

Site Evaluation: The most recent site evaluation was conducted on May 8, 2006 (QA Check: September 

10, 2009). 

This site is located in Lexington County in the city of Cayce. 

The PM10 is a Special Purpose Monitor and the site was 

established as a source-oriented monitor in an area where there 

is a concentration of industrial particulate sources. In addition to 

PM10, Cayce CMS has instruments for measuring precipitation, 

wind speed and wind direction. Cayce CMS represents middle 

scale concentrations of PM10 in an area dominated by point 

sources and dust reentrained by mobile sources. The sample 

inlets are 4.9 meters from the nearest road.

The data collected at this location is intended for use by DHEC, 

local government and industry to enable quick response to the impacts of local activities to minimize 

emissions. 

Changes for 2012: 

This site will be terminated at the end of 2011. PM10 concentrations are measured at other nearby 

locations and monitoring at this site has been determined to be duplicative. DHEC priorities and the 

establishment of new requirements from the EPA necessitate the termination of this site to free up 

resources.

Comments Received and Department Response

Comments from Mike Kennedy (Progress Energy)

I have reviewed DHEC’s 2012 Ambient Monitoring Plan, and it looks very good, but I have one minor 

comment/question. This may have been brought up or discovered already, but in the table entitled “2010 

Criteria Pollutant Design Values” that begins on page 9 the units for the annual and 24-hour SO2 values 

appear to be incorrect. They are shown at the top of each column as ppm, but they are likely in ppb (those 

values would be extraordinarily high if they were in ppm). 

The Department agrees with this comment. The table entitled “2010 Criteria Pollutant Design Values” 

had an inadvertent error with the unit labels for the annual and SO2 Design Values. This table has been 

corrected to indicate the units are ppb not ppm.

Comments from Sandra Yudice (Greenville County)

p. 6: Legend does not conform to SC areas. 

The map on page 6 of the monitoring plan is generated by the United States Census and is used to show 

its official names for South Carolina’s Metropolitan Statistical Areas and the areas they comprise. The 

Department has no control over the legend within this map.

p. 9: the Hillcrest Middle School ozone monitor is missing 

The Design Value for the Hillcrest Middle School ozone (and those for several other sites and pollutants) 

is not listed because the monitors do not yet have three complete years of monitoring data. In order to 

calculate a design value for most parameters, three complete years of data are required. Hillcrest 

Middle School will have three complete years of ozone monitoring data at the conclusion of the 2011 

ozone season and will be included in next year’s Design Value listing. 

p. 18: Greenville County and private industries would like to participate in the search of a new site for the 

Taylors PM2.5 monitor. 

The Department acknowledges and appreciates Greenville County’s offer to assist in locating a 

replacement site for the Taylors PM2.5 monitor. The Department is operating PM2.5 samplers at the 

Hillcrest monitoring site (page 21) to provide an alternate, representative data for population exposure in 

an area outside of the city center The Department will contact interested stakeholders to discuss possible 

alternatives to represent the MSA.

P.25, the description of the monitor says it’s in a “rural” area, but this is arguable depending on what is 

being used for the definitions of urban and rural. It is located in the SPATS area which is an ‘urbanized’ 

area by federal standards, but it is not located within any town or city municipal boundaries (it is just on 

the outside edge of Wellford’s boundary), and the immediate area is not very densely populated. We 

would just ask that if they want to say it’s in a rural area that they define what is rural and what is urban 

and use those definitions consistently throughout the report. 

In the narrative for the North Spartanburg site ‘rural’ is used as a descriptor of the immediate area, not a 

designation. The monitor location is only coincidentally outside the boundaries of the defined 

Spartanburg Urbanized Area (US Census, 2000). Where common terms are used in an officially defined 

context, the Department will endeavor to make usage clear. 
Comment from Robert vandenMeiracker (TRC)

SC DHEC posted the draft 2012 Network Description and Ambient Air Network Monitoring Plan (Plan) 

on its website for public comment. The Plan consists of a description of the South Carolina ambient 

monitoring network and an accounting of any changes to the network planned over the next 18 months. 

On behalf of Johnson Controls Battery Group, Inc.’s (JCI) Florence Recycling Center, TRC 

Environmental Corporation (TRC) is providing comment on the proposed changes to the lead monitoring 

network. 

Pages 54 and 57 of the Plan provide specifications for monitoring air surrounding the Florence Recycling 

Center using three monitors as described in the agreement referenced in the Department’s revised Plan. 

JCI comments that each of these monitors should be identified as Special Purpose Monitors (SPM)’s until 

such time as JCI’s actual lead emissions exceed 0.50 tons per year; then it may be appropriate to 

designate on of the monitors as a SLAMS site as addressed at 40 CFR §58.10(a)(4) (consistent with 

Appendix D). 

The Department agrees with this comment and will change the designation of the lead samplers at the 

Florence Recycling Center site to reflect that all three will initially be designated as Special Purpose 

Monitors. The Department will re-evaluate the designation of these samplers once data is available and 

revise the designations when appropriate.

Comments from Chap Hurst (Pickens County)

Location of Clemson CMS 

The location of the Clemson CMS is not conducive to the air quality of Pickens County as a whole. The 

location picks up particles derived in Atlanta and Charlotte brought to the area by the jet stream. The 

location is also misleading due to its proximity to Interstate 85 (in Anderson County) and several 

industrial sites in Anderson. 

Readings 

Upon reviewing recent emissions inventory calculations, it has been determined that the readings from the 

Clemson monitor are inconclusive. The calculation of the total pollutants may also include vehicles, 

watercrafts and equipment that are used in neighboring counties – not Pickens County. 

Based on explanations we have been given, there is not a direct correlation between the actual number of 

vehicles that are permanently housed in Pickens County and the number of trips vehicles (from other 

areas) make passing through the area via Interstate 85. If one is to believe that vehicles are the main 

contributor to high levels of ozone, this theory does not apply in Pickens County. Pickens County has 

fewer vehicles and far less road trips per day than neighboring counties, but has one of the highest 

readings. Therefore, one must conclude that the pollutants are being transferred from other areas and are 

to blame for the exceptionally high readings. 

The Department acknowledges receipt of this comment.
