What the agency says

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Missouri State Implementation Plan (SIP) related to the control of emissions during petroleum liquid storage, loading, and transfer in the St. Louis area. The revisions to this rule include revising the tank size threshold applicability of the rule, adding incorporations by reference to other State rules, adding definitions specific to the rule, revising unnecessarily restrictive or duplicative language, adding a streamlined process for modifications to vapor recovery systems at gasoline dispensing facilities and thereby eliminating the associated permitting requirement, and clarifying rule language on testing and reporting. The revisions make this provision consistent with a similar rule that is applicable to the Kansas City, Missouri area and regulates the same type of facilities. The EPA's final approval of this rule revision is being done in accordance with the requirements of the CAA.
