Richland County, SCiv 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 co mprise 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

d esignations, 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 ass essments.

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 po llutants 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, 20 11 through December 31, 201 2. 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 o zone 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 annu al 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 s ites that are suitable for comparison against the PM 2.5 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 desig nations, 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 Ai rv 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: Pub lic 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

DH EC ) 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

announcements 1

.

• Availability of the proposed 2012 Network Descript ion and Ambient Air Network Monitoring Plan for public review and

comment ran from June 2 to July 1, 201 1. All recorded participants who registered in

the outreach and discussion activities were notified when the plan became available for

review.

DHEC is c ommitted 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.

Networ k Operation

The primary responsibility for the operation of

the South Carolina A mbient Air M onitoring

N etwork is assigned to t he Division of Air

1 http://www.scdhec.gov/environment/baq/AmbientAi rMonitoring/ Quality Analysis in the Bureau of

Environmental Services (Division) . The

Division e stablishes

, maintains and op erates the sites and instruments that make up the network and performs the analysis of samples collected as part of routine monitoring or special projects.

D ata generated by the network for comparison to the NAAQS is verif i ed to be accurate and reported by the Division and stored in the national AQS database.

C riteria 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 an d 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

activitie s 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 i nternal 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 crit eria.

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

S iting Criteria ) and th e data collected by these samplers and monitors is suitable for comparison to the NAAQS

. DHEC furthervi intends to assure that the samplers and monitors comply with as many of the recommendations contained within the regulations and applicable guidance docum ents as is possible.

An element of the Quality System 2 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 metho ds, 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. T he 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, 2008.1 

### 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 m onitoring 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 fol lowing information:

Site Description

The h eader 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 s ite identification

number used in AQS i n 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 sit e 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. pl an , 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 de termine 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 vis it 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

monito ring 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 ch aracteristics 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 scale2 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 stu dies. 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 purp oses:

• 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,

• Det ermine 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, Neig hborhood

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 revie wed 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 r equirements for air qu ality surveillance systems provide for the establishment of a network of monitoring stations designated SLAMS that measure ambient concentrations of those pollutants for which3 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 Purpo se 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

associat ed 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 requirement s 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 metropolita n area provide data for daily index reporting. Data collected from continuous

monitors for Ozone and PM 2.5 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

C harleston -North Charleston areas.

Probe Height

The monitor or sampler p robe 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 characte rized non

equivalent methods may be used.

• Particulate Matter ≤ 10 microns (PM 10 )

PM 10 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. Inte rmittent samplers collect a 24 -hou r 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 c ubic meter (μg/m 3 ). 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 PM 10 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 (PM 2.5 )

A ll PM 2.5 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 hou rs of the end of the sample run and are kept cool (4°C or cooler) during transit to meet the thirty

day 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 atmosp here 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 re

weighed 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/m 3

.

Continuous PM 2.5 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 t hrough 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 compu ted 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.

PM 2.5 Speciation sampling and analysis

In addition to operating PM 2.5 samplers that allow measurement of only PM 2.5 mass concentration, DHEC also operates PM 2.5 speciation samplers that collect samples that are analyzed to determine the chemical makeup of PM 2.5

. Samples are collected on a set of three cartridges

over a 24 -h our sampling period. The individual cartridges contain denuders and filters designed to efficiently capture the major components of

PM 2.5

. After collection, the samples are shipped in ice chests to the EPA contract laboratory for analysis.

At the laborator y 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 D ioxide (SO 2 )

Instrum ents 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 hour ly 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

automa tically 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 D ivision 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 di luted to give varying known5 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 (O 3 )

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 D ivision automated central data acquisition system.

Monitors are routinely calibrated using portable

ozone transfer standards. Calibration curves are prepared for each instrument an d each measurement is automatically compared to this curve before entry into the data acquisition

system.

• Nitrogen Dioxide (NO 2 )

The FRM chemiluminescence and UV methods are used in monitoring the nitrogen dioxide

concentration in the ambient air. The cont inuous 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 containin g 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 (NO 2 ). These

known concentrations are s upplied 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 a ir

q uality are perfor m ed using s ampling and continuous monitoring. Sampling frequency is the

indicator of how often a measurement is made and reported.

Sampling typically in volves collection of a sample over a period (typically 24 hour s, 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

avera ges 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 ana lysis 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 SO 2 

### – Population Weighted Emissions Index (PWEI)

On June 22, 2010, the EPA finalized revisions to the SO 2 NAAQS. As part of this rulemaking, the EPA set new minimum monitoring requirements for CBSA based on population and SO 2 emissions. The following table presents each CBSA’s population, SO 2 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 inv entory 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 SO 2 emissions (measured in tons using the latest National Emissions Inventory data). This product is divid ed 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 requ ire 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 Emissi ons Inventory, there are no facilities in Sou t h Carolina with lead emissions greater than 0.5 tpy.

On May 7, 2010, DHEC issued a n air synthetic minor construction permit to Johnson Controls Battery Group for the Florence Recycling Center (Permit No. 1040 -0129- CA). Under a settlement agreement 5
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 th is facility can be found in the Florence MSA section of this plan under the site name

“Johnson Controls.”

### Network Development

The Monitoring Network provides data to support an array of decisions ranging from development of emissions strategies to protect and i mprove 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

netw ork 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 rur al 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 be tter 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 P articulate S urveillance

- rotation of SPM PM 2.5 sites through areas with higher rates of growth and c hanges 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 PM 2.5 conce ntrations 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

- limi ted 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

monitor ing site.63 

### Sites Discontinued

The remainder of this document contains information on monitoring sites DHEC is scheduling for discontinuance. These sites will be discontinued by January 1, 2012 unless otherwise indicated.

### 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 PM 10 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 a ccess. 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 rep resentative 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 nearb y to establish a wind tower to maintain meteorological monitoring in the area.

### Cayce CMS

CSA/MSA: Columbia-Newberry CSA / Columbia MSA AQS Site ID: 45-063-0009

Location: 609 F rink Street County: Lexington

Coordinates: +33.973389, -81.052675

Date Established: October 26, 1991

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 PM 10 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

PM 10 , Cayce CMS has instruments for measuring precipitation, wind speed and wind direction. Cayce CMS represents middle

scale concentrations of PM 10 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. PM 10 concentrations are mea sured 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 wou ld 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 SO 2 D esign V alues. 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 S chool ozone ( and th ose for several other sites and pollutants)

is not listed because the monitor s 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 participat e 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 PM 2.5 monitor. The Department is operating PM 2.5 samplers at the

H

illcrest 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 locate d 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 t he 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 D epartment will endeavor to make usage clear.

## Comment from Robert vandenMeiracker (TRC)

SC DHEC posted the draft 201 2 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 par ticles 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.
