EPA Proposes Approval of NY SO2 Transport Plan
The EPA proposes to approve New York's plan showing it will not send too much sulfur dioxide (SO2) pollution to other states for the 2010 1-hour SO2 standard (75 ppb). The agency focused on large point sources (those over 100 tons per year) within about 50 kilometers of state lines and found monitoring data (2019-2023 and 2021-2023 design values) below the 75 ppb level in nearby areas, so the EPA proposes New York's plan meets the interstate 'good neighbor' test.
No New Federal Costs for Small Businesses
The EPA says this proposed approval merely accepts New York law as meeting the Clean Air Act 'good neighbor' requirements and does not impose additional federal requirements beyond state law. The action is certified as not having a significant economic impact on a substantial number of small entities.
