benzene levels & federal intervention

EPA should develop a national ambient air standard for Benzene. Louisiana's benzene standard is more than twice as lenient as the Texas standard, which is over 30 times looser than that of Massachusetts. Without a National Ambient Air Standard for Benzene, States will continue to enforce different standards in different ways. St Bernard Parish residents deserve the most protective standards resulting in the least amount of exposure; not more.

Benzene is like asbestos, there is no safe exposure level, and chronic airborne benzene exposure is associated with leukaemia and other health affects.

According to the World Health Organization: "Benzene is carcinogenic to humans, and no safe level of exposure can be recommended. For general guidance, the concentrations of airborne benzene associated with an excess lifetime risk of leukaemia of 10−4 , 10−5 and 10−6 are 17, 1.7 and 0.17 μg/m3 , respectively."

 https://www.who.int/ipcs/features/benzene.pdf

The EPA now requires benzene fenceline monitoring in the oil refinery sector, but not around other benzene emitting plants. When the 2 week adjusted average is above 9 ug/m3, the oil refinery must file an additional report and conduct root cause analysis and take action to reduce the benzene level. However, this is looking more like another fox watching the hen house project.

Residents and grassroots stakeholders like Louisiana Bucket Brigade and Environmental Integrity Project wanted public access to the real time data, and not just the two week "adjusted" averages.


According to this EIP article,"Anne Rolfes, Director of the Louisiana Bucket Brigade, an environmental advocacy group, complained that the people of Chalmette, Louisiana, are being exposed to benzene from the Chalmette Refining plant at dangerous levels.  The benzene concentration detected along the refinery fenceline in 2019 was 37 percent higher than EPA action levels.
“It should not require a federal intervention for Chalmette Refining to take action on a cancer causing chemical like benzene,” Rolfes said. “Chalmette Refining’s reckless release of benzene threatens the people who live in the neighborhood right across the street, and a school that is less than a mile away.”
EPA’s benzene regulations have their origin in a 2012 lawsuit that the Environmental Integrity Project (EIP) and allies filed on behalf of seven community and environmental groups, including Air Alliance Houston and the Louisiana Bucket Brigade. The lawsuit complained that EPA missed its deadline to review and update toxic air standards for oil refineries by more than a decade.
For years, these local groups had been fighting for stronger protection from refinery pollution, including problems associated with flaring and malfunctions. In response, EPA imposed new regulations for oil refineries designed to reduce the amount of hazardous pollution these companies spew into the air. The new rules, first implemented in 2018, require refineries to set up monitors around the perimeter of their plants to measure concentrations of benzene leaving the property.
As part of the monitoring requirement, refineries must collect air samples at the plant fenceline every two weeks. Refineries then determine the amount of benzene actually coming from the facility by correcting for background or any nearby or offsite sources. If the highest measurement of benzene coming from the facility exceeds an average of 9 micrograms per cubic meter of air over a one-year period, the EPA regulations require the facility to conduct an analysis to determine the root cause of the problems causing the toxic emissions and to then take action to lower those concentrations.

Another AIR ALERT

The 8-hour average Ozone [O3] reading in Meraux, Louisiana, in St Bernard Parish  in the Joe Davies Elementary school area, has failed to meet the EPA health standard for ground level ozone for the second time in recent weeks. We can all do our part to be part of the solution. Gas Stations in St Bernard Parish can install vapor reducing nozzles, heavy industry can install Best Control Technology, and residents can use a cleaner commute such as carpool, bike, or mass transit. To protect your lungs, it is recommended you stay indoors on Air Alert days and refrain from burning trash or leaves, and using grills or gas powered lawn and garden equipment. 







SEE LDEQ NOTICES BELOW for two exceedances on May 9 2018 and LDEQ Notice from the April 28 2018 exceedance of 8-hour average Ozone reading at same location.

The most recent exceedance for O3 8-hour average was April 28 2018. " ... the U.S. Environmental Protection Agency (EPA) strengthened the National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb), based on extensive scientific evidence about ozone’s effects on public health and welfare. The updated standards will improve public health protection, particularly for at-risk groups including children, older adults, people of all ages who have lung diseases such as asthma, and people who are active outdoors, especially outdoor workers, among others."

dangers of high frequency sounds



From time to time high frequency noise emanates from nearby plants and becomes more than just a nuisance to residents; it becomes a public health issue. 

Over many years, the LDEQ dismissed this known offsite effect as a local jurisdiction issue, and local officials claimed lack of personnel and lack of monitors to enforce. The plants claim weekend staffing issues.

Currently, local ordinances tend to only address the loudness of noise level measured in decibels and not the pitch or frequency of noise measured in hertz (Hz).

According to the American Hearing Research Foundation " Generally noise induce hearing loss occurs at a pitch of about 2000 - 4000 Hz". 

The dangers of high frequency sounds should be addressed by both local officials and the Louisiana DEQ. Both State and Parish officials could develop ordinances to protect the public's hearing. At the very least any noise monitors in the community should include frequency measurements, and those measurements should be posted in real time to a publicly accessible website. 

This is an issue the residents of St Bernard have been begging for help with. There is no lack of knowledge of the source of the noise. It is a well documented offsite affect.  There seems to be alot of attention on the worker's hearing protection but none for the human beings who reside just on the other side of the fence.

In this article link below, about the Sonic Attack in Cuba, "the incident has brought up questions over how quickly sound waves can cause hearing loss without warning signs.
http://www.healthline.com/health-news/sonic-attack-hearing-loss#3

"Dr. Darius Kohan, director of otology and neurotology at Lenox Hill Hospital/Manhattan Eye, Ear, and Throat Hospital, said that it’s possible for sound to irreparably damage the ear without a person knowing their hearing is being impacted."
What are we waiting for?

where not to put a park

68530.

where not to put a park

by sbcitizens, 09/17/13 6:46 PM

don't put a park in the oil spill area; its too close to the tank farm and contaminated air; that's why the air monitor is in that area, its bad air.

don't put a park next to the solid waste ditch and ponds; there is a required exclusion zone for solid waste areas up to 250 feet or 500 feet and that part of the oil spill property is where nothing is supposed to be.

don't put a park where special interests groups are forcing the park on others.

don't put a park where the streets are going to be removed or where the street lights are not maintained.

put a new park where kids and old people and family and neighbors will be safe and protected, where people live close enough to just walk to the park and not have to drive. put a new park where the people who live in that area want one.

can we even afford another park? don't think we would even be talking about another park until all the previous neighborhood and recreational parks are renovated. so, why are parish employees advocating for a park in the oil spill green belt? are they advocating for the oil company? if you receive a survey for where the next park ought to go, think about what that park is supposed to be and why certain parties would push to spend limited resources on something we don't need, don't want, and would be liable for anyway.

Ozone in St Bernard Parish, Louisiana

St Bernard Parish Air Quality


UNLESS ................................................
“Unless someone like you cares a whole awful lot,
Nothing is going to get better. It's not.”
― Dr. Seuss, The Lorax


Ozone is formed when nitrates of oxygen (NOx) and volatile organic compounds (VOCs) combine together in sunlight. One solution to high concentrations of ground level ozone is the use of fuel that contains less benzene and lower sulfur content. Some communities switch public transportation buses and school buses to bio diesel or natural gas or use ultra low sulfur content fuels in an attempt to reduce Ozone pollution.

Ozone Attainment Status


The Good News on Ozone levels in St Bernard is there seems to be enough lead time to address the Ozone issue before being designated or labeled non-attainment for Ozone. It's a violation of the Ozone standard when the 8-hour average of ground level ozone does not remain below the current standard of 75 parts per billion. (The old standard was an 8-hour average of 80 parts per billion). An area would be recommended for designation (or "labeled") non-attainment when the annual fourth-highest daily maximum 8-hour concentration of Ozone, averaged over 3 years, is 75 ppb or higher. http://www.epa.gov/air/criteria.html In St Bernard Parish, Ozone levels are sampled at the LDEQ "Meraux" site at Joe Davies Elementary School.

According to data on EPA's Air Data website, St Bernard Parish's current 3 year average for Ozone is around 73 ppb and we all need to do our part to keep it below 75 ppb. (Based on annual fourth highest daily maximum 8 hour concentration of Ozone for 2010 at 74 ppb , for 2011 at 76 ppb , for 2012 at 69ppb. { [(74+76+69) / 3 ] = 73 ppb} From http://www.epa.gov/airdata/ left hand column menu, select Monitor Values, select Ozone, select Louisiana, select year, scroll down to 8-hour averages.) LDEQ's "Meraux" site readings assessible here , under site data, select "Meraux".
.
So, now is the time for all of us to do our part to be part of the solution, to work with coalitions to reduce Ozone, and to protect what little is left of our good air quality. Part of success stories, like St Bernard's in the late 1990's and Baton Rouge's recent success to reduce Ozone, are coalitions that take "Early Action" to reduce pollution before its so bad. For Ozone, this would include even further reduction of NOx (nitrates of oxygen) and VOCs (volatile organic compounds such as benzene, ethylbenzene, toluene, xylene and others) at all nearby industries, and the use of "Clean Fuels" in buses, trucks and other vehicles, including barge and ship traffic on the Mississippi River.

Clean Fuels create dirty neighborhoods

But Ozone and Clean Fuel Projects are sort of a Catch 22 in communities where the Clean Fuel is manufactured. When EPA mandates lower benzene and sulfur content in Clean Fuels, the refining of crude oil into "Clean Fuels" results in more sulfur dioxide and VOCs, such as benzene, in the fenceline neighborhoods, unless the LDEQ requires more stringent pollution controls. It seems Clean Fuels Projects that began around the late 1990's, or early 2000, were "grandfathered in" and LDEQ didnot require the state-of-the-art pollution controls. The result: St Bernard Parish is now the poster child for sulfur dioxide pollution, with concentration levels three times higher than the one-hour sulfur health limit, the 2nd highest sulfur dioxide concentrations in the United States, second only to Hawaiin communities that seem to be around active volcanoes.  The EPA is expected to make its official designation of St Bernard Parish as non-attainment for sulfur dioxide health standards.

Calcined petroleum coke (CPC) also contributes sulfur emissions. Louisiana is the largest CPC producing region  in the world outside of China, with several Rain CII coke plants accounting for more than half of Louisiana’s CPC production. Rain CII's facility in Chalmette operates under a variance and has received several additional exemptions to bypass the pyroscrubber and vent emissions for upto 500 hours a year. Rain CII Chalmette recently applied for a "minor" modification to its Title V air permit to make the variance permanent and to increase the total of bypass or vent time to 836 hours. This "minor" application is separate from its December 2012 short-term variance for 336 hours that LDEQ pulled in January 2013 admist concerns of high sulfur levels in the adjacent neighborhood.  As a "minor" modification, the Title V air permit is subject to less stringent pollution controls than "major" modifications.  Minor modifications do not require pubic notice or a cost benefit analysis. St Bernard Parish Government has requested LDEQ conduct a public hearing on the "minor" modification at Rain CII. This will be a good opportunity for concerned people and government bodies, such as the HRQL, to submit pubic comment.

Sulfur Dioxide Status


The Louisiana Department of Environmental Quality recommended EPA designate St Bernard Parish air quality non-attainment for sulfur dioxide   (SO2).  EPA is expected to make its official designation on June 3, 2013.  LDEQ must submit a State Implementation Plan (SIP) by mid-2014; the SIP must demonstrate the area will reach attainment by 2017.  Ambient air monitors display hourly averages for sulfur dioxide.  It is a health violation when the one-hour average is 75 parts per billion (ppb) SO2 or higher.  An area is considered non-attainment when the 3 year average of the 99th percentile of hourly average readings is 75 ppb or higher.  According to EPA's AirData website,  St. Bernard's current SO2 3 year average of the 99th percentiles is 255 ppb (two hundred fifty-five)  and it needs to be 75 ppb or lower.  Clearly there is alot a work ahead to bring sulfur dioxide pollution levels down.

BUT that is not the whole picture. Complete perimeter monitoring and more stringent pollution controls are paramount to the goal of reducing sulfur dioxide emissions.  The readings in the EPA data bank are samples or readings when the wind is just right to make a direct hit or "air strike" on the monitor. There is a real need for perimeter or fenceline monitoring. We should demand more air monitors, perhaps placing additional monitors back on Mehle Avenue and back in Algiers on the west bank. Maybe adding monitors on the east side of ExxonMobil's refinery, perhaps around Lloyds Ave, sort of in-line with the Chalmette Vista monitor that is on E Chalmette Circle, and another one on the east side of Valero Energy's refinery, but not as far east as the Meraux monitor at Joe Davies School. 
As an example:

From the Chalmette High School monitor data 2007 - 2011, the maximum hourly readings for each year were  95, 116, 54, 80, and 85 ppb SO2.  Although the SO2 standard back then was a 24-hour average of 140 ppb and an annual limit of 30 ppb,  the 3 year average was 64 ppb, approaching the current one-hour average 75 ppb limit. (The three year average of the last three available annual 99th percentiles is 64 parts per billion).   

From the Meraux monitor data 2008 - 2012, the maxmium hourly readings for each year were 161, 36, 29, 58, and 59 ppb SO2. There seems to be an upward trend in sulfur dioxide concentrations in Meraux.  In 2009, Murphy Oil installed interm, temporary pollution controls while in settlement talks with Concerned Citizens.  The resultant EPA consent decree requires the new owner, Valero Energy, install a Flare Gas Recovery System by 2017, operate an air monitor on Ventura Drive in Chalmette, reduce various pollution emissions,  increase on-site monitoring, and provide for public forums.  In the meantime, Murphy Oil installed a benzene saturation unit without state-of-the-art pollution controls, adding to both the sulfur concentrations and VOC emissions.  There is pending citizen enforcement action on the benzene unit.  Valero Energy recently received a "minor" modification permit to revamp and expand the hydrocracker unit to increase production without more stringent pollution controls; this will result in even more sulfur dioxide pollution.  In 2013, the EPA will require "Tier 3" Mandate compliance for even lower sulfur content in gasoline products.  Both Valero Energy and ExxonMobil refineries will have to modify their plants to comply.  If those modifications do not require more stringent pollution controls, the result will be increased sufur dioxide and VOCs.

The Valero Energy Ventura Drive monitor is not part of the EPA databank, and does not provide maxium reading data, although that information is available in the public forums.  Valero Energy's Ventura monitor has its own share of sulfur health violations.  

So, the problem is all over, and not just in Chalmette Vista. 
.




From the Chalmette Vista site, 2007 - 2012 the air quality in that neighborhood had a total of 298 sulfur health violations, just in 2011 alone.  Maximum hourly average readings for each year (2007 - 2012) were 477, 363, 373, 378, 375, and 242 SO2.  Residents residing in Chalmette Vista are suffering the health effects and "unless someone like you cares a whole awful lot,Nothing is going to get better. It's not."
 
It is imperative our community take action to reduce sulfur dioxide concentrations.  Perimeter monitoring and more stringent pollution controls are paramount to this goal. 
 



Two of the oil refinery plants in St Bernard Parish operate under an EPA consent decree, both results of Citizen Enforcement Action by residents of St Bernard Parish. Any State Plan to reduce sulfur emissions in St Bernard Parish, will be reviewed by EPA.  The other plant, the coke plant, operates on a variance for up to 500 hour bypass and recently applied to LDEQ to permanently increase that bypass to 836 hours. SBPG recently requested a public hearing on that permit (for Rain CII Carbon) and that will be an excellent opportunity for the HRQL an other government officials to submit public comments to the LDEQ.


Sulfur Dioxide data and analysis available at EPA's AirData site,  under Monitor Values .

Mehle Avenue, Arabi
2000 through 2005: Total number of sulfur health violations 102

(Number of sulfur health violations 15, 19, 7, 12, 34, and 15 for each respective year)

Annual 99th percentiles sulfur dioxide 108, 141, 89, 93, and 161, and 177 ppb for each respective year. Maximum hourly average readings 124, 191, 127, 138, 305, and 184 ppb for each respective year. The 3 year average based on the last annual 99th percentiles would have been 143 ppb, well over the current 75 ppb standard.

Algiers (Orleans Parish) "Entergy" site
2006 - 2007 : Total number of sulfur health violations not counted by LDEQ because the Algiers site was part of a special monitoring project.

Maxium hourly average readings 154 ppb and 306 ppb SO2. There is a clear need for monitoring in these west bank communities.
Monitoring information for the Algiers "Entergy" site on the westbank of the Mississippi River is not included in the EPA databank. It is available in the LDEQ Air Quality 2009 Report (link below). This Algiers air monitor was located on property owned by Entergy Corporation.  The "Entergy" site, along with the Chalmette Vista and Chalmette High School air monitors were made possible through the hard work and dedication of Mr. Ken Ford, founding president of St Bernard Citizens for Environmental Quality, his neighbors, and the Louisiana Bucket Brigade. http://www.deq.louisiana.gov/portal/Portals/0/AirQualityAssessment/Analysis/Data/Chalmette-Report--Final,%202009.pdf
The EPA website does not include data for the Chalmette High School and the Chalmette Vista sites for 2005 and 2006 due to insuffient number of readings because of down time from Hurricane Katrina. More information on these sites is included in the LDEQ Air Monitor Report 2009 at the link above.
Chalmette High School
2007 through 2011: Total number of sulfur health violations 7  The EPA website does not include the 2005 and 2006 data due to insufficient number of readings because of down time in the aftermath of Hurricane Katrina.  More information is included in the LDEQ 2009 Report . 

( Number of sulfur health violations 2, 3, 0, 1, and 1 for each respective year)

Annual 99th percentiles sulfur dioxide 67, 73, 49, 57, and 85 ppb for each respective year. Maximum hourly average readings 95, 116, 54, 80, and 85 ppb for each respective year.  Maximum hourly average reading in 2006 was 95 ppb, per the LDEQ 2009 Report . 
The 3 year average based on the last available annual 99th percentiles would have been 64 parts per billion. This was a sign that we were approaching non-attainment. If a monitor could be added east of ExxonMobil, but not as far as Chalmette High School, there would be a clearer indication of sulfur concentrations in that area.

Chalmette Vista E. Chalmette Circle

2007 through 2012: Total number of sulfur health violations 1,321  The EPA website does not include the 2005 and 2006 data due to insufficient number of readings because of down time in the aftermath of Hurricane Katrina. More information is included in the LDEQ 2009 Report .

( Number of sulfur health violations 211, 233, 284, 206, 298, and 89 for each respective year)

Annual 99th percentiles sulfur dioxide 349, 330, 314, 248, 300, and 217 ppb SO2 for each respective year. Maximum hourly average readings 477, 363, 373, 378, 375, and 242 ppb SO2 for each respective year. Maximum reading in 2006 was 271, per LDEQ 2009 Report

The current 3 year average (of the 99th percentile) at Chalmette Vista is 255 ppb.  We need to get the sulfur concentrations to below 75 ppb to be in attainment for sulfur dioxide.

Meraux Mistrot Drive Joe Davies School

2008 through 2012: Total number of sulfur health violations 2

(Number of sulfur health violations 2, 0, 0, 0, and 0 for each respective year)

Annual 99th percentiles sulfur dioxide 49, 24, 24, 30, and 29 ppb SO2 for each respective year. Maximum hourly average readings 161, 36, 29, 58, and 59 ppb SO2 for each respective year.

The current 3 year average (of the 99th percentile) at Meraux is 28 ppb SO2, and trending upward, with increasing maximum hourly averages each year.

Air Quality Report for 2012


  2012 Air Quality Report for St Bernard Parish

St. Bernard Parish air quality failed to meet pollution standards in 2012 for sulfur dioxide on 29 days, for PM2.5 on 34 days, for PM10 on six days, and for hydrogen sulfide on eight days. 

Based on air samples at three community air monitors , there were 170 days or 45% of the year when residents had to suffer acute exposure level of sulfur dioxide at 10 parts per billion (ppb) or higher. Sulfur dioxide levels failed to meet EPA's 75 ppb  one-hour health standard on 29 days. 
 
All too often the hydrogen sulfide levels failed to meet the EPA recommended daily exposure level of 1.4 ppb.  On eight days, the hydrogen sulfide levels failed to meet a health standard of 30 ppb -- this is the health standard in the State of California; the State of Louisiana has no such limit.  On 17 days, hydrogen sulfide levels reached 20 ppb or higher.

Particulate matter PM2.5 failed to meet the EPA daily standard of 35 micrograms per cubic meter of air (ug/m3) on 34 days; PM10 failed to meet the EPA daily standard of 150 ug/m3 on six days.

Ozone readings were higher than EPA's standard of 75 ppb on eight days.  The only air quality alerts from DEQ in 2012 were for "Ozone Action Days" and during a persistent marsh fire in January 2012. 

Data excludes the month of January and the fireworks timeline for July Fourth and New Year's Eve.

2012 Monthly Air Quality Readings

The air in St. Bernard Parish failed to meet PM2.5 pollution limits on at least 34 days, with high readings of 69 ug/m3, 67 ug/m3, and 61 ug/m3 at DEQ’s ‘Ch_Vista’ site, well above the 35 ug/m3 standard.

PM10  readings failed to meet pollution limits on at least two days in Chalmette Vista with high readings of 167 ug/m3 and 150 ug/m3; and, on four days at Valero Energy’s Ventura Drive site with high readings of 238 ug/m3, 187 ug/m3, 183 ug/m3, 166 ug/m3, and 153 ug/m3,, well above the 150 ug/m3 standard .
Air quality in St. Bernard Parish failed to meet the one-hour sulfur health standard of 75 ppb on 29 days, with some of the highest readings at DEQ’s ‘Ch_Vista’site of 241 ppb, 229 ppb, 216 ppb, 211 ppb, 184 ppb, 174 ppb, 164 ppb, and 148 ppb. 

The sulfur levels at Valero Energy’s Ventura Drive site failed to meet the health standard on one day with 120 ppb, and had 34 days of acute exposure level of 10 ppb or higher, with five days of sulfur readings at 30 ppb or higher. Some of the higher sulfur readings at Valero Energy’s Ventura Drive site were 120 ppb, 48 ppb, 45 ppb and 41 ppb. The DEQ ‘Meraux’ site at Joe Davies Elementary school had 47 days of acute exposure level of 10 ppb or higher and three days of 30 ppb or higher, with some of its highest readings at 59 ppb, 43 ppb, and 33 ppb.
In 2012 the highest hydrogen sulfide reading was 78 ppb at the Valero Energy's Ventura Drive site, which also had four additional days that failed to meet the 30 ppb health limit.  Some of the higher readings at Valero Energy's Ventura Drive site were 78 ppb, 62 ppb, 44 ppb and 35 ppb. 

DEQ's 'Ch_Vista' site had twelve days of hydrogen sulfide readings above 20 ppb, with four days that failed to meet the 30 ppb health limit.  Some of the higher Chalmette Vista readings were 53 ppb, 49 ppb, 46 ppb, and 43 ppb. DEQ’s ‘Meraux’ site at Joe Davies Elementary school had high hydrogen sulfide readings of 27 ppb and 20 ppb.

Data excludes the month of January and the fireworks timelines of July Fourth and New Year's Eve.

September 2012 air quality readings

Updated through month end:
Some of the higher air quality readings in September 2012 from the three air monitors in St. Bernard Parish; data accessible at these links.

LDEQ Ch_Vista Site select site data, select Ch_Vista
Valero's Ventura Site current link
LDEQ Meraux Site select site data, select Meraux





Shown above, location of the three community air monitors : LDEQ's sites at Ch_Vista and Meraux, and Valero's site at Ventura. The former "Entergy", across the river, was shut down after Hurricane Gustav in 2008 as was the former Chalmette High site, closed in 2009. These closures were based on the previous sulfur standards and perhaps would still be operating if based on the new one-hour health standard limit of 75 parts per billion sulfur dioxide.

The EPA recommended1.4 parts per billion (ppb) daily exposure to hydrogen sulfide (H2S) was exceeded throughout the month.…..inhaling more than this concentration on a daily basis poses an appreciable risk of deleterious effects.
http://www.epa.gov/iris/toxreviews/0061tr.pdf . "Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs." "Long-term, low-level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory, and dizziness."

The State of California air quality standard limits hydrogen sulfide to 30 ppb H2S; that standard was surpassed at all three sites, with the highest reading of 62 ppb H2S at Ventura. The State of Louisiana has no such standard.

The EPA health standard for sulfur dioxide (SO2) is 75 ppb SO2.
St. Bernard Parish is non-attainment for the sulfur health standard.  On September 29th and 30th sulfur levels exceeded health standards with some of the highest readings at 229 ppb SO2.   According to Louisiana DEQ, when sulfur dioxide levels reach 12 ppb SO2 it triggers headaches and adverse health and quality of life. Sulfur dioxide levels were at or above this adverse level on ten days this month.

The standard for particulate matter PM2.5 is 35; that standard was violated twice this month.

benzene and 1, 3-butadiene cause no odors at lower concentrations but are great health concern for long time exposure enen in lower concentrations." - LDEQ 2009 St Bernard Air Monitoring Project Final Report

Below are some of the higher air quality readings for the month of September 2012.
