Proposed State Implementation Plan Revision 

Section 110(a)(2)(A)-(M) Clean Air Act Requirements

George Hawkins, Director 
A State Implementation Plan (SIP) is a plan for each state that identifies how that state will attain and/or maintain the primary and secondary 

National Ambient Air Quality Standards (NAAQS). The SIP is a complex, fluid document containing regulations, source-specific requirements, nonregulatory items such as plans and inventories, and in some cases additional requirements promulgated by the U.S. Environmental Protection Agency 

(EPA). The initial SIPs for states were approved by EPA on May 31, 1972. SIPs can be revised by the state with EPA approval as necessary. The 

federally enforceable SIP for District ofColumbia is compiled in 40 CFR Part 52 Subpart J. 

This SIP revision incorporates the requirements ofSection 11O(a)(2)(A)-(M) ofthe Clean Air Act (CAA) which have not been previously addressed. 

This SIP revision is a compilation of elements that describe how the District ofColumbia is implementing the PM2.5 NAAQS. The elements ofthis 

SIP revision, once approved by EPA, will provide a federally enforceable written confirmation ofhow the District ofColumbia will continue to 

comply with the Section 110(a)(2)(A)-(M) requirements ofthe CAA. 

Legislative authority for the District ofColumbia air quality program is codified in 40 CFR Part 52 Subpart J, which gives the District Department of 

the Environment the power and duty to implement the provisions ofthe CAA in the District ofColumbia. 

Those requirements of Section 11O(a)(2)(A)-(M) that are already in the approved SIP or recently submitted SIP revisions relate to: enforceable 

emission limits and schedules for compliance; monitoring, source testing and emissions reporting; recordkeeping and reporting requirements; and 

permit fees.

Section 110(a) element Summary of element The District ofColumbia's Implementation Plan 

§11 O(a)(2)(B) provide for establishment and 

operation of appropriate devices, 

methods, systems, and procedures 

necessary to monitor, compile, and 

analyze data on ambient air quality, 

and upon request, make such data 

available to the Administrator; 

The District Department ofthe Environment (DDOE) 

maintains and operates a multi-station PM2.5 network to 

measure ambient PM2.5 levels within District ofColumbia for 

comparison to the national ambient air quality standard 

(NAAQS) as required by 40 CFR Part 58. PM2.5 monitoring 

is currently performed at various locations throughout the 

District ofColumbia. All data are measured using U.S. 

Environmental Protection Agency (EPA) approved methods as 

either Reference or Equivalent methods; all monitors are 

subjected to the quality assurance requirements of 40 CFR Part 

58, Appendix A; and all samplers are located at sites that have 

met the minimum requirements of Part 58, Appendix E. The 

data are submitted to the EPA's Air Quality System (AQS), in 

a timely manner in accordance to the schedule prescribed by 

the EPA in 40 CFR Part 58 and in accordance with the Section 

105 grant commitment (sub-objective 1.1.1). 

In order to keep EPA informed of changes to the sampling 

network, DDOE provides EPA Region III with prior 

notification of any planned changes to the network. As 

needed, details ofthese changes and anticipated approvals of 

the changes are communicated to EPA. On an annual basis, 

DDOE sends EPA a summary table of all the changes to the 

network. This summary also provides for a description of each 

change, the reason for each change, and any other information 

relevant to the change. DDOE submits data to the AQS 

system in a timely manner, pursuant to the schedule prescribed 

by the EPA in 40 CFR Part 58. 

§11O(a)(2)(E)(i) provide 

(i) necessary assurances that the state 

(or, except where the Administrator

personnel, funding, and authority under 

state (and, as appropriate, local) law to 

carry out such implementation plan (and 

is not prohibited by any provision of 

federal or state law from carrying out 

such implementation plan or portion 

thereof); 

§8-101 et seq.) to carry out its state implementation plan (SIP) 

obligations with respect to the PM2.5 standards and to revise 

the SIP as necessary. The primary sources of funding for the 

implementation ofthe PM2.5 requirement are the Section 105 

grant funds provided to DDOE, fees collected under the Title 

V program, and District funding. DDOE believes that the 

District has and will continue to have adequate funding and 

personnel to carry out the SIP with respect to PM2.5 

requirements. 

DDOE does not anticipate the need for additional 

resources to carry out the plan for the PM2.5 standard 

beyond those which have been utilized to date to meet 

other current programmatic demands. 

DDOE is not prohibited by any District law from carrying out 

any part ofthe implementation plan. 

§110(a)(2)(F) require, as may be prescribed by the 

Administrator­

(iii) correlation ofsuch reports by the 

state agency with any emission 

limitations or standards established 

pursuant to this Act, which reports shall 

be available at reasonable times for 

public inspection; 

DDOE analyzes emissions data and correlates such data with 

any applicable emission limitations or standards. Section 105 

grants are used to support air quality inspectors, and part of 

their process is to compare source emissions to emission 

limitations and standards. All reports are available to the 

public under the District ofColumbia Freedom ofInformation 

Act (FOIA) (D.C. Official Code §2-531 et seq.) 

§11 0(a)(2)(H) provide for revision ofsuch plan­

(i) from time to time as may be 

necessary to take account ofrevisions 

of such national primary or secondary 

ambient air quality standard or the 

availability of improved or more 

expeditious methods of attaining such 

standard, and 

The District of Columbia will review and revise its SIP from 

time to time as may be necessary to take account ofrevisions 

ofsuch primary or secondary NAAQS or the availability of 

improved or more expeditious methods of attaining such 

standard and whenever the Administrator finds on the basis of 

information available to the Administrator that the plan is 

substantially inadequate to attain the NAAQS which it 

implements or to otherwise comply with any additional

(iii) except as provided in paragraph

plan is substantially inadequate to

standard which it implements, or to 

otherwise comply with any additional 

requirements established under this 

Act; 

requirements established under the CAA. When plan revisions 

are necessary, the regional planning process through the 

Metropolitan Washington Air Quality Committee (MWAQC) 

or its successors, coordinated with the transportation planning 

agencies, is used. The District has adequate authority under 

the District ofColumbia Air Pollution Control Act of 1984, 

effective March 25, 1985 (D.c. Law 5-165, D.C. official Code 

§ 8-101 et seq.) to revise the SIP.

annual summary of all monitoring data, including exceedances 

and violations ofstandards, are published on EPA's Air

§110(a)(2)(K) provide for: 

(i) the performance ofsuch air quality 

modeling as the Administrator may 

prescribe for the purpose ofpredicting 

the effect on ambient air quality of any 

emissions of any air pollutant for which 

the Administrator has established a 

national ambient air quality standard, 

and 

(ii) the submission, upon request, of 

data related to such air quality modeling 

to the Administrator; 

(i) The performance of air quality modeling is a SIP process 

required to predict the effect on ambient air quality necessary 

to demonstrate attainment ofthe NAAQS. In support ofthe 

1997 PM2.5 NAAQS, the District's air quality modeling for 

PM2.5 was performed as a part ofthe regional SIP planning 

process through MWAQC. As part offuture PM2.5 SIPs, the 

District's air quality modeling will be performed as part ofthe 

regional SIP planning process through MWAQC or its 

successors. 

(ii) In support ofthe 1997 PM2.5 NAAQS, the PM.25 

modeling performed by MWAQC was submitted as part ofthe 

District's PM2.5 SIP submittal on April 4, 2008. In the future,

DC will continue to submit air quality modeling data as part of 

its PM2.5 SIP submissions developed as part ofthe regional 

planning process through MWAQC or its successors as 

required under sub-objective 1.1.1 ofthe District's Section 105 

grant. Upon request, DC will submit current and future data 

relating to such air quality modeling to the Administrator.
