## Proposed State Implementation Plan Revision Section 11O(a)(2)(A)-(M) Clean Air Act Requirements for Ozone

January 2008

DistrictDepartment ofthe Environment 51 N StreetNE, 6 th Floor Washington, DC 20002 George Hawkins, DirectorA State Implementation Plan (SIP) is aplan for each state that identifies how that state will attain and/or maintainthe 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 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 110(a)(2)(A)-(M) ofthe Clean Air Act (CAA) which have notbeen previously addressed. This SIP revision is a compilation ofelements that describe how the District ofColumbia is implementing the eight-hour ozone NAAQS. The elements ofthis SIP revision, once approved by EPA, will provide a federally enforceable written confirmation ofhow the District ofColumbiawill continue to comply with the Section 11 0(a)(2) 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 Environmentthe power and duty to implementthe provisions ofthe CAA in the District ofColumbia.

Those requirements ofSection 11 0(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. Some requirements, such as those for intergovernmental consultation, air quality modeling and compliance with part D ofthe CAA, are fulfilled during the development and submission to EPA as a SIP revision ofattainmentplans and related requirements due under subpart 1 and, in the case ofozone, subpart 2 ofthe CAA. In the case ofozone, District ofColumbia has submitted the ozone nonattainment area SIP.

2provide for establishment and operation ofappropriate 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 maintains and operates a multi-station ozone networkto measure ambient

ozone levels within District ofColumbia for comparison to the NAAQS as required by 40 CFR Part 58. Seasonal (April

— October) and annual ozone monitoring is currently performed at various locations throughoutthe District ofColumbia. All data is measured using U.S. Environmental Protection Agency (EPA) approved methods as either Reference or Equivalent monitors; all monitors are subjected to the quality assurance requirements of40 CFR Part 58, Appendix A; and all samplers

are located at sites that have metthe minimum requirements of Part 58, Appendix E. The data is submitted to the EPA’s Air Quality System (AQS) system, in atimely manner in accordance to the schedule prescribed by the EPA in 40 CFR Part 58.

In order to keep EPA informed ofchanges to the sampling network, the District Department ofthe Environmentprovides EPA Region III with priornotification ofany planned changes to the network. As needed, details ofthese changes and anticipated approvals ofthe changes are communicated to EPA. On an annual basis, the District Department ofthe Environment sends EPA a summary table ofall the changes to the network. This summary also provides for a description of each change, the reason for each change, and any other information relevantto the change. The District Department ofthe Environment submits datato the AQS system, in a timely manner, pursuant to the scheduled prescribed by the EPA in 40 CFR Part 58.

The District Department ofthe Environment analyzes the data

3(i) necessary assurances thatthe state (or, except where the Administrator deems inappropriate, the general purpose local government or governments, or a regional agency designated by the state

or general purpose local governments for suchpurpose) will have adequate personnel, funding, and authority under state (and, as appropriate, local) law to carry out such implementation plan (and is notprohibited by any provision of federal or state law from carrying out such implementation plan orportion thereof); to determine attainment status ofareas and analyzed trends as evinced by the June 12, 2007 attainment demonstration state implementationplan (SIP) revision submittal for the District.

The District assures EPA that ithas adequate authority under the District ofColumbia Air Pollution Control Act of 1984, effective March 15, 1985 (D.C. Law 5-165, D.C. Official Code §8-101 et seq.) to carry out its SIP obligations withrespect to the 8-hour ozone standard and to revise the SIP as necessary. The primary sources offunding for the implementation ofthe 8-hour ozone requirement is the Section 105 grant matching funds provided by the District and fees collected underthe Title V fee program. The District Department ofthe Environmentbelieves thatthe Districthas adequate funding and personnel to carry out the SIP with respectto 8-hour ozone requirements. Should EPA determine that the District Department ofthe Environment lacks adequate personnel to carry out the Plans, EPA may issue a finding withrespectto that deficiency, which the Districtwould have a legal obligation to correct.

The District Department ofthe Environment does not anticipate the need for additional resources to carryout the plan for the 8-hour standard beyond those which have been utilized to date to meetthe 1-hour standard, preparation ofthe plans submitted to date and other currentprogrammatic demands.
