Approval and Promulgation of Air Quality Implementation Plans; Maryland; Revisions to the Control of Iron and Steel Production Installations

摘要

EPA is taking direct final action to approve revisions to the Maryland State Implementation Plan (SIP). The revisions consist of amendments to the applicable test methods for use at iron and steel facilities. The revisions also establish a visible emission standard for Basic Oxygen Furnace (BOF) Shops at integrated steel mills. Finally the revisions remove certain obsolete requirements related to coke ovens and hearth furnaces. These SIP revisions were submitted by the Maryland Department of the Environment (MDE) on April 2, 1992 and October 10, 2000. EPA is approving these revisions to the Maryland SIP in accordance with the requirements of the Clean Air Act.
