South Carolina Certification 

Clean Air Act Section 110(a)(1) and (2) 

PM2.5 Requirements 

Each of the basic or infrastructure requirements enumerated in the October 2, 2007, guidance 

memo is listed below along with the corresponding State statute granting the Department the 

necessary authority to implement each State Implementation Plan (SIP) element. 

Emission limits and other control measures: Section 110(a)(2)(A) of the Clean Air Act 

(CAA) requires SIPs to include enforceable emission limits and other control measures, means or 

techniques, schedules for compliance and other related matters. South Carolina Air Pollution 

Control Regulation 61-62.5, Standard No. 2, Ambient Air Quality Standards serves to establish 

emission limits for particulate matter (PM), while Regulation 61-62.1, Definitions and General 

Requirements addresses required control measures, means, and techniques. Section 48-1-50(23) 

of the 1976 South Carolina Code of Laws, as amended (hereinafter referred to as S.C. Code 

Ann.) provides the Department with the statutory authority to, “Adopt emission and effluent 

control regulations standards and limitations that are applicable to the entire State, that are 

applicable only within specified areas or zones of the State, or that are applicable only when a 

specified class of pollutant is present.” 

Ambient air quality monitoring/data system: Section 110(a)(2)(B) of the CAA requires SIPs 

to include provisions to provide for establishment and operation of ambient air quality monitors, 

collecting and analyzing ambient air quality data, and presentation of these data available to EPA 

upon request. Regulation 61.62.5, Standard No. 7, Prevention of Significant Deterioration, along 

with the South Carolina Network Description and Ambient Air Network Monitoring Plan

(conditionally approved by EPA in November 2007), provide for an ambient air quality 

monitoring system in the State. S.C. Code Ann. § 48-1-50(14) provides the Department with the 

necessary statutory authority to “Collect and disseminate information on air and water control.” 

Program for enforcement of control measures: Section 110(a)(2)(C) of the CAA requires 

States to include a program that provides for enforcement of all SIP measures and the regulation 

of construction of new or modified stationary sources to meet prevention of significant 

deterioration (PSD) and nonattainment new source review (NSR) requirements. Regulation 61-

62.5, Standard No. 7, Prevention of Significant Deterioration, and Regulation 61-62.5, Standard 

7.1, Nonattainment New Source Review, apply to the construction of any new major stationary 

source or any project at an existing major stationary source in an area designated as attainment or 

unclassifiable. On July 1, 2005, the Department submitted its PSD/NSR SIP revision to EPA for 

approval. In August 2007, the EPA sent to the State a draft conditional approval letter that 

indicated modifications to the State PSD and NSR rules were necessary. On November 20, 

2007, the Department sent to the EPA a written response outlining its commitment to making 

those modifications. Upon publication of the EPA’s final notice of conditional approval of these 

State rules in the Federal Register, the Department will thereafter commence with necessary 

changes to the regulations. S.C. Code Ann. § 48-1-50(10) provides the Department with the 

statutory authority to, “Require to be submitted to it and consider for approval plans for disposal 

system or source or any parts thereof and inspect the construction thereof for compliance with 
Attachment 1 

2 

the approved plans.” Further, S.C. Code Ann. § 48-1-50(11) provides the Department with the 

statutory authority to “Administer penalties as otherwise provided herein for violations of this 

chapter, including any order, permit, regulation or standards.” 

Interstate transport: Section 110(a)(2)(D) of the CAA requires SIPs to include provisions 

prohibiting any source or other type of emissions activity in one State from contributing 

significantly to nonattainment of the NAAQS in another State. States are required to submit 

110(a)(2)(D)(i) plans to demonstrate compliance with these provisions. On June 25, 2007, South 

Carolina submitted its 110(a)(2)(D)(i) plan to EPA. In this submittal, South Carolina made a 

demonstration that it met the required four-pronged set of criteria as outlined below. 

State SIPs must contain adequate provisions prohibiting any source or other type of 

emissions activity within the State from emitting any air pollutants in amounts that will: 

1. Contribute significantly to nonattainment of NAQQS for areas in another state. (Prong 1) 

South Carolina’s Clean Air Interstate Rule (CAIR) became state-effective on June 22, 

2007. On December 10, 2007, EPA’s approval of South Carolina’s CAIR as a direct final 

rule became effective. South Carolina’s participation in the CAIR trading program will 

satisfy this criterion. 

2. Interfere with maintenance of NAAQS by any other State. (Prong 2) 

Again South Carolina’s implementation of CAIR and participation in the trading 

program will satisfy this criterion. 

3. Interfere with measures required to meet the implementation plan for any other State 

related to Prevention of Significant Deterioration (PSD). (Prong 3) 

South Carolina’s participation in the CAIR trading program; implementation of 

Regulation 61-62.5, Standard No. 7, and Regulation 61-62.5, Standard No. 7.1 (both of 

which provide for a preconstruction review and permitting program for major sources of 

air pollutants) collectively satisfy this criterion. 

 

4. Interfere with measures required to meet the implementation plan for any other State 

related to Regional Haze and Visibility. (Prong 4) 

South Carolina has satisfied this criterion through its Regional Haze Implementation 

Plan (submitted to EPA on December 21, 2007). The Regional Haze Implementation 

Plan was developed in consultation with other state, Federal Land Managers (FLMs), 

and regional planning organizations. 

Adequate resources: Section 110(a)(2)(E) of the CAA requires states to provide for adequate 

personnel, funding and legal authority under State Law to carry out its SIP and related issues. 

The Department is provided its legal authority to establish a SIP and implement related plans, in 

general, under S.C. Code Ann. Section 48, Title 1. Specifically, S.C. Code Ann. § 48-1-50(12) 
Attachment 1 

3 

grants the Department the statutory authority to, “Accept, receive and administer grants or other 

funds or gifts for the purpose of carrying out any of the purposes of this chapter; accept, receive 

and receipt for Federal money given by the Federal government under any Federal law to the 

State of South Carolina for air or water control activities, surveys or programs.” S.C. Code Ann. 

Section 48, Title 2 grants the Department statutory authority to establish environmental 

protection funds. Additionally, Regulation 61-30, Environmental Protection Fees, provides the 

Department with the ability to assess fees for environmental permitting programs. The 

Department implements the SIP in accordance with the provisions on S.C. Code Ann. § 1-23-40 

and S.C. Code Ann. Section 48, Title 1. 

Stationary source monitoring system: Section 110(a)(2)(F) of the CAA requires States to 

establish a system to monitor emissions from stationary sources and to submit periodic emissions 

reports. Regulation 61-62.1, Definitions and General Requirements, provides for an emission 

inventory plan that establishes reporting requirements, while S.C. Code Ann. § 48-1-22 provides 

the Department with the necessary statutory authority to “Require the owner of operator of any 

source or disposal system to establish and maintain such operation al records; make reports; 

install, use and maintain monitoring equipment or methods; samples and analyze emissions or 

discharges in accordance with prescribed methods, at locations, intervals, and procedures as the 

Department shall prescribe; and provide such other information as the Department reasonably 

may require.” 

Emergency power: Section 110(a)(2)(G) of the CAA requires state to provide for authority to 

address activities causing imminent and substantial endangerment to public health, including 

contingency plans to implement the emergency episode provisions in their SIPs. Regulation 61-

62.3, Air Pollution Episodes requires that the Department provide for contingency measures 

when air pollution episode or exceedance that may lead to substantial threat to the health or 

persons in the State or region. S.C. Code Ann. § 48-1-290 grants the Department the statutory 

authority as follows: “Whenever the Department fins that an emergency exists requiring 

immediate action to protect the public health or property, the Department, with concurrent notice 

to the Governor, may without notice or hearing issue an order reciting the existence of such an 

emergency and requiring that such action be taken as the Department deems necessary to meet 

the emergency. Such order shall be effective immediately. Any person to whom such order is 

directed shall comply therewith immediately, but an application to the Department or by 

direction of the Governor shall be afforded a hearing within forty-eight hours. On the basis of 

such hearing the Department shall continue such order in effect, revoke it or modify it. 

Regardless of whether a hearing is held, the Department shall revoke all emergency orders as 

soon as conditions or operations change to the extent that an emergency no longer exists.” S.C. 

Code Ann. § 1-23-130 provides the Department with the statutory authority to establish 

emergency regulations. 

Future SIP revisions: Section 110(a)(2)(H) of the CAA requires States to have the authority to 

revise their SIPs in response to changes in the NAAQS, availability of improved methods for 

attaining the NAAQS, or in response to an EPA finding that the SIP is substantially inadequate. 

S.C. Code Ann. Section 48, Title 1 provides the Department the necessary statutory authority to 

revise the SIP to accommodate changes in the NAAQS. 
Attachment 1

Consultation with government officials: Section 110(a)(2)(J) of the CAA requires States to 

provide a process for consultation with local governments and FLMs carrying out NAAQS 

implementation requirements pursuant to section 121 relating to consultation. Regulation 61-

62.5, Standard No. 7, Prevention of Significant Deterioration as well as provisions in separate 

implementation plans (such as the five-year review process under the Regional Haze 

Implementation Plan, which allows for consultation between appropriate state, local, and tribal 

air pollution control agencies as well as the corresponding FLMs) provide for continued 

consultation with government officials. Additionally, S.C. Code § 48-1-50(8) provides the 

Department with the necessary statutory authority to “Cooperate with the governments of the 

United States or other states or State agencies or organizations, officials, or unofficial, in respect 

to pollution control matters or for the formulation of interstate pollution control compacts or 

agreements.” 

Public notification: Section 110(a)(2)(J) of the CAA further requires States to notify the public 

in NAAQS are exceeded in an area and to enhance public awareness of measures that can be 

taken to prevent exceedances. The Department has several public notice mechanisms in place to 

notify the public of PM and other pollutant forecasting and has an extensive outreach program to 

educate the public and promote voluntary emission reduction measures. Regulation 61-62.3, Air 

Pollution Episodes requires that the Department notify the public of any air pollution episode or 

exceedance. S.C. Code Ann. § 48-1-60 established that, “Classification and standards of quality 

and purity of the environment [are] authorized after notice and hearing.” 

PSD and visibility protection: Section 110(a)(2)(J) of the CAA also requires State to meet 

applicable requirements of Part C related to PSD and visibility protection. Regulation 61.62.5, 

Standard No. 7, Prevention of Significant Deterioration, as well as the Regional Haze SIP 

together address visibility protection. 

Air quality modeling/data: Section 110(a)(2)(K) of the CAA requires that SIPs provide for 

performing air quality modeling so that effects on air quality of emissions from NAAQS 

pollutants can be predicted and submission of such data to EPA can be made. Regulations 61-

62.5, Standards No. 2, Ambient Air Quality Standards and R. 61-62.5, Standard No. 7, 

Prevention of Significant Deterioration (as adopted in the SIP) require that air modeling be 

conducted to determine permit applicability. 

Permitting fees: Section 110(a)(2)(L) of the CAA requires SIPs to require each major 

stationary source to pay permitting fees to cover the costs of reviewing, approving, 

implementing, and enforcing a permit. Pursuant to S.C. Code Ann. § 48-2-50 (1993), the 

Department shall charge fees for environmental programs it administers pursuant to federal and 

state law and regulations. Regulation 61-30, Environmental Protection Fees, prescribes fees 

applicable to applicants and holders of permits, licenses, certificates, certifications, and 

registrations as well as establishes procedures for the payment of fees, provides for the 

assessment of penalties for nonpayment, and establishes an appeals process for refuting fees. 

Consultation/participation by affected local entities: Section 110(a)(2)(M) of the CAA 

requires States to provide for consultation and participation in SIP development by local political 

subdivision affected by the SIP. Regulation 61-62.5, Standard No. 7, Prevention of Significant 
Attachment 1 

5 

Deterioration (as adopted by the SIP) requires that the Department notify the public of the 

application, preliminary determination, degree of incremental consumption, and the opportunity 

for comment prior to making a final permitting decision. Likewise, S.C. Code Ann. § 48-1-50(8) 

allows the Department to “Cooperate with the governments of the United States or other states or 

State agencies or organizations, officials, or unofficial, in respect to pollution control matters or 

for the formulation of interstate pollution control compacts or agreements.” Other provisions 

regarding public hearings and the regulation development process are included in S.C. Code 

Ann. Section 48, Title 1 in general, and S.C. Code Ann. § 1-23-40 (the Administrative 

Procedures Act). The Department has worked closely with local political subdivisions in 

developing the Transportation Conformity SIP, the Regional Haze Implementation Plan, the 

Early Action Compacts, and the 8-hour Ozone Attainment Demonstration for the York, County, 

South Carolina, portion of the Metrolina nonattainment area. 

Other Notes: In September 2007, the Department also submitted its 8-hour Ozone attainment 

demonstration for the York County portion of the Metrolina Nonattainment Area. This 

document was developed in consultation with many interagency (both Federal and State) 

partners. In June 2007, the Department submitted its 110(a)(2)(D)(i) plan as final. In October 

2007, the Department submitted a 110(a)(1) 8-hour ozone maintenance plan for Cherokee 

County, SC (which had previously been subject to a one-hour ozone maintenance plan). On 

December 13, 2007, the Department submitted a letter certifying that the infrastructure elements 

associated with the 8-hour ozone standard have been addressed. 

Together these submissions, along with South Carolina's existing Air Quality State 

Implementation Plan, address the necessary elements of section 110(a)(1) and (2) of the CAA.
