Approval and Promulgation of Air Quality Implementation Plans; Illinois; Ford Motor Company Adjusted Standard

Résumé

EPA is proposing to approve a January 4, 2006, request from Illinois for a site specific revision to the State Implementation Plan (SIP) for the Ford Motor Company (Ford). The revision will allow Ford to discontinue use of its Stage II vapor recovery system (Stage II) at its Chicago Assembly Plant. In place of Stage II, Ford will comply with the standards of the Federal onboard refueling vapor recovery (ORVR) regulations, as well as meet other minor conditions. The exclusive use of ORVR will provide at least an equivalent amount of gasoline vapor capture as Stage II.
