non-attainment for SO2

Air modeling based on current permit limits would demonstrate exceedance of the one hour health standard for sulfur dioxide (75 ppb).   LDEQ would then determine different permit limits for the facilities; these lower permit limits would model attainment. 
LDEQ does not want to do that.

Update around the 25 minute mark

Lower SO2 emissions! Our health is suffering from such high concentrations of sulfur dioxide. According to EPA’s technical document for St Bernard Parish's designation of nonattainment, annual SO2 emissions at Rain CII Carbon are 4,284 tons per year; that is 8,568,000 pounds sulfur dioxide!! Rain CII's permit allows up to 7,000 tons per year SO2!!  (Murphy Oil) Valero Energy’s Meraux plant is a 125,000 barrels per day capacity with 753 tons per year SO2. However, Valero Energy’s St Charles plant is a 270,000 barrel per day capacity with only 238 tons per year SO2. Compare to ExxonMobil’s Chalmette plant, with 192,000 barrels per day and 250 tons per year SO2. Both Valero Energy and ExxonMobil operate several other refineries with better control technology that results in lower emissions. Why aren’t they required to make the same investment in St. Bernard?

ExxonMobil Chalmette is actually permitted to release up to 462 tons per year sulfur dioxide.  Both ExxonMobil and Valero Energy shut several units in 2012 and 2013 at various times for lengthy turnarounds. Modeling should provide information about what total permitted sulfur dioxide emissions will keep the air safe.  Currently, the air in St Bernard is not safe, it fails to meet health standards.

Sulfur dioxide non-attainment

The sulfur dioxide standard is 75 parts per billion.  According to EPA's AirData website Monitor Values,  St Bernard Parish's 3 year average of the annual 99th percentile sulfur dioxide concentration (2010 - 2012)

Chalmette Vista      255 parts per billion sulfur dioxide

Ventura Drive           data not available, not part of EPA/DEQ monitors.  The second highest reading in 2012 was 48 ppb SO2.  As of  2/11/2013, the second highest reading to date is 138 ppb.

Meraux site               28 part per billion sulfur dioxide
Meraux site data: 28 parts per billion SO2 – 2012 Design value (2010-2012 99th Percentile data). (2011 Design value of 26 ppb for 2009 – 2011 data and 2010 Design value of 32 ppb for 2008-2010.)

For the years 2008 – 2012, the "Meraux" site’s highest annual hourly average readings illustrate the upward trend in sulfur dioxide concentrations from recent plant modifications. The 2011 and 2012‘s highest annual hourly average readings of 58 ppb and 59 ppb are up from the 2009 and 2010‘s highest annual hourly average readings of 36 ppb and 29 ppb. In October 2012, around the same time of reported flaring at nearby Valero Energy, the "Meraux" site hourly average reading of 59 ppb included 5-minute readings of 76, 92, 109, and 88 ppb. These are the levels of sulfur dioxide that a school child on  the play yard would be exposed to within that 20 minute time frame. Evidence links such short-term exposure with adverse respiratory effects; this is particularly important when children are exercising or playing.  These peaks in sulfur levels illustrate the public health concern at Joe Davies Elementary School, where the "Meraux" site is located. 

" compliance with ambient air quality standards does not authorize emissions in excess of emission limitations."

In this action EPA intends to propose to issue findings of substantial inadequacy for certain States whose SIPs are inconsistent with the CAA (Clean Air Act) and with current EPA rules and policies concerning treatment of a source's excess emissions during periods of startup, shutdown, and malfunction (SSM).
