  1. NEW JERSEY 1-HR SULFUR DIOXIDE (SO2) ATTAINMENT DEMONSTRATION Joel Leon March 2, 2012

  2. 1-hr SO2 ATTAINMENT DEMONSTRATION • On 6/2/10, USEPA revised primary SO2 NAAQS • 75 parts per billion, (196 ug/m3) one hour standard • NJ recommended entire state be designated as unclassifiable, except area around Portland Power Plant • Required attainment date of August, 2017

  3. 1-hr SO2 ATTAINMENT DEMONSTRATION • NJ must demonstrate attainment and maintenance of standard by 6/2/2013 (may be extended by a year) • Section 110(a)(1) and (2) of State Implementation Plan submittal • Attainment demonstration with dispersion modeling • Emission inventory/Control Strategy/Contingency Plan • Plan for verification of continued attainment • Since August, 2017 is the attainment date, lower sulfur content limits in fuel (NJAC 7:27-9) can be incorporated

  4. 1-hr SO2 ATTAINMENT DEMONSTRATION • Proposed guidance recommends dispersion modeling • Facilities with SO2 actual emissions of 100 tons per year (tpy) or greater • NJ identified up to twelve facilities that may need to be modeled • > 100 tpy of SO2 actual emissions averaged over the years 2008 -2010 • Some facilities eliminated when lower sulfur in fuel limits reduce 2017 potential SO2 emissions to below 100 tpy

  5. 1-hr SO2 ATTAINMENT DEMONSTRATION • Overall approach is to model in 2 or 3 phases • Phase 1 – Evaluate facilities with >100 tpy SO2 with ambient air ambient SO2 readings • Phase 2 – Evaluate any facilities within a large percentage (~60-80%) of standard along with any minor SO2 sources in area • Phase 3 – Further evaluate applicable facility’s maximum pound per hour SO2 emissions and stack parameters if exceeding or near standard

  6. 1-hr SO2 ATTAINMENT DEMONSTRATION • The facilities will be notified that SO2 modeling is necessary • Draft protocol has been developed and will be finalized after EPA input is received • Department will begin outreach to affected facilities • Facilities can conduct own modeling or the Department can conduct the modeling
