Ozone (8-Hour NAAQS) Attainment Demonstration for NY Metro Area - Final Proposed Revision


Ground-level ozone, a primary ingredient in smog, is formed when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react chemically in the presence of sunlight. Cars, trucks, power plants and industrial facilities are primary sources of these emissions. Ozone pollution is a concern during the summer months when the weather conditions needed to form ground-level ozone - sunshine and hot temperatures - normally occur. Ozone is unhealthy to breathe, especially for people with respiratory diseases and for children, the elderly and adults who are active outdoors. Symptoms include reduced lung function and chest pain, and can lead to respiratory diseases such as bronchitis or asthma.

On April 15, 2005, the United States Environmental Protection Agency (EPA) designated the New York-N. New Jersey-Long Island, NY-NJ-CT metropolitan area (NYMA) as a moderate non-attainment area that exceeds the health-based standards for ozone. The National Ambient Air Quality Standard for ozone is 0.08 parts per million, measured over an 8-hour period. Pursuant to the Clean Air Act Amendments of 1990, states have three years from the date of designation to submit a State Implementation Plan (SIP) demonstrating how the nonattainment area will attain the standard. Moderate nonattainment areas are required to demonstrate attainment within six years of the effective date of designation, or June 15, 2010.

On August 9, 2007, the New York State Department of Environmental Conservation (Department) submitted a proposed revision to the ozone SIP for NYMA demonstrating attainment by June 15, 2013 (2010 - 2012 data). This final proposed revision incorporates minor changes made in response to comments received from EPA and the Manufacturers of Emission Controls Association on that proposal. It is also consistent with the Department's request, submitted under separate cover, to have NYMA reclassified from "moderate" to "serious" nonattainment. Serious nonattainment areas are required to demonstrate attainment within nine years of designation, or June 15, 2013.

This final revision to the NYMA SIP is consistent with August 9, 2007 proposal and contains the 2002 baseline emission inventory, projection inventories for 2008, 2011 and 2012, a predictive photo-chemical modeling attainment demonstration by June 15, 2013, and the control measures and programs that will be implemented by the state in order to demonstrate attainment with the 8- hour ozone standard.
