# §52.2089. Control strategy: carbon monoxide.

- (a) **Approval—** On September 22, 2008, the Rhode Island Department of Environmental Management submitted a request to establish a limited maintenance plan for the Providence Rhode Island carbon monoxide attainment area for the remainder of the second ten-year maintenance plan. The State of Rhode Island has committed to year round carbon monoxide monitoring at the East Providence Photochemical Assessment Monitoring Station (PAMS) site; re-establishing downtown Providence CO monitoring if criteria specified in the Limited Maintenance Plan are triggered; and, ensuring that project-level carbon monoxide evaluations of transportation projects in the maintenance area are conducted. The limited maintenance plan satisfies all applicable requirements of [section 175A](/cfr/40/175A.md) of the Clean Air Act. Approval of a limited maintenance plan is conditioned on maintaining levels of ambient carbon monoxide levels below the required limited maintenance plan 8-hour carbon monoxide design value criterion of 7.65 parts per million. If the Limited Maintenance Plan criterion is no longer satisfied, Rhode Island must develop a full maintenance plan to meet Clean Air Act requirements.
- (b) [Reserved]
