Exemption of Point Source Volatile Organic Compounds for BART 

Purposes 

The State of Florida has determined through modeling that Volatile Organic Compounds (VOC) 

from point sources are not anticipated to cause or contribute significantly to any impairment of 

visibility in Class I areas and should be exempt for BART purposes. 

Method 

The State of Florida determined through modeling that VOCs from point sources are not 

anticipated to cause or contribute significantly to any impairment of visibility in Class I areas. 

Modeling was conducted through The Visibility Improvement State and Tribal Association of 

the Southeast (VISTAS). VISTAS is a collaborative effort of state governments, tribal 

governments, and various federal agencies established to initiate and coordinate activities 

associated with the management of regional haze, visibility and other air quality issues in the 

Southeastern United States. VISTAS contracted with Georgia Institute of Technology to 

perform model sensitivity runs to determine the impact of point source VOCs on visibility in 

Class I areas. 

Georgia Tech performed emission sensitivities to examine the impact of emission reductions on 

regional haze, annual PM2.5, and 8-hour ozone concentrations using CMAQv4.4_SOAmods on 

the VISTAS 12 km modeling domain, using the 2009 OTW (on the way) BaseD emissions. One 

such sensitivity run reduced anthropogenic, point source VOCs by 100%. The purpose was to 

quantify the impact of VOC emissions from VISTAS BART sources on Class I areas. Two 

periods were examined representing a summer and winter (annual) timeframe : June 1-July 10, 

2002 and November 19 – December 19, 2002. The approach included calculating the extinction 

coefficient in dv (deciviews), then determining the maximum impact of point source VOCs. The 

chart below shows the impact on the following twenty-two Class I areas within the VISTAS 

domain. 2

 Maximum Point VOC Impact 

Conclusions 

The results show that the maximum impact from eliminating all point source VOC emissions in 

the VISTAS 12 km domain is less than a 0.5 dv for all Class I areas in the VISTAS domain. 

Given that the fraction of the total point source VOC emissions that are also BART-eligible in 

the state of Florida is small, the expected impact of controlling VOCs from a BART source 

would be much less than the 0.5 dv threshold. VISTAS and the State of Florida conclude that 

VOCs from point sources are not a visibility impairing pollutant for BART purposes and that 

BART-eligible sources do not need to consider VOC emissions. 

Treatment of Ammonia Emissions for BART Purposes 

Similar to its treatment of VOCs, EPA guidance allows States the discretion to decide whether or 

not ammonia emissions are to be considered for BART purposes based on evaluations of the 

contributions of the emissions to haze at Class I areas in their areas of influence. One approach a 

State can use to determine whether applying BART will be needed is to evaluate the haze 

impacts of all current emissions from all BART-eligible sources in the State. If the impact from 

all sources in the state is less than the contribution threshold established by the State, 0.5 dv for 

Florida, then source by source analysis for BART is not needed. 

The State of Florida has determined through modeling that ammonia (NH3) emissions from 

point sources are not anticipated to cause or contribute significantly to any impairment of 

visibility in Class I areas and should be exempt for BART purposes.

Method 

The State of Florida determined through modeling that ammonia emissions from point sources 

are not anticipated to cause or contribute significantly to any impairment of visibility in Class I 

areas in or near Florida. 

VISTAS contracted with Georgia Institute of Technology to perform model sensitivity runs to 

determine the impact of point source ammonia on visibility in Class I areas. 

Georgia Tech performed emission sensitivities to examine the impact of emission reductions on 

regional haze using CMAQv4.5 with SOA mods on the VISTAS 12 km modeling domain, using 

the VISTAS 2009 OTW (on the way) Base F4 emissions. One such sensitivity run reduced, 

BART-eligible source ammonia by 100%. The purpose was to quantify the impact of ammonia 

emissions from VISTAS BART sources on Class I areas. Two periods were examined: June 1-

July 10, 2002 and November 19 – December 19, 2002. The approach included calculating the 

extinction coefficient in dv (deciviews), then determining the maximum impact of BARTeligible source ammonia. The chart below, taken from the VISTAS analysis, shows the impact 

on the following twenty-two Class I areas within the VISTAS domain. 2 

Maximum NH3 Impact - Maximum contributions of all BART-eligible NH3 point sources in 

the VISTAS region to haze in Class I areas during the CMAQ-modeled periods. 

The chart shows the largest haze impact in delta dv over the two timeframes at each Class I area. 

These delta dv changes represent the haze contribution of all BART source ammonia emissions 

relative to assumed natural haze levels. The natural haze levels are based on EPA-default annual 

average natural concentrations for the East and monthly-varying “climatologically 

representative” relative humidity at each Class I area.

During the periods modeled the ammonia emissions from all BART-eligible sources contributed 

more than 0.5 dv to haze at Mammoth Cave National Park (MACA), Kentucky; Mingo 

Wilderness (MING), Missouri, Cape Romain National Wildlife Refuge Area (ROMA) South 

Carolina, and Swanquarter National Wildlife Refuge (SWAN), North Carolina. All of these 

Class 1 areas are located more than 300 km from Florida BART-eligible sources. 

Conclusions 

The BART requirements of the regional haze rule allow states to determine whether or not 

ammonia is to be considered a visibility impairing pollutant to be addressed for BART purposes. 

NH3 emissions from BART sources may impair visibility; however the majority of NH3 

emissions in the VISTAS region are from a few BART sources. Removal of the large NH3 

emission sources results in minimal impact on visibility at Class I areas in the VISTAS region. 

At their discretion states may ask those few large sources to evaluate NH3 impacts and potential 

controls for NH3.

Protocol includes the evaluation of three scenarios for emission reductions 

sufficient to meet the exemption criteria. Only scenarios A and B have been 

evaluated because scenario C was not deemed consistent with current permit 

conditions and was dismissed by the department. A federally enforceable permit 

requiring the implementation of either A or B scenarios is being issued. 

Exemption modeling:

Emissions – 

SO2, NOx, and PM 

Two emission reduction scenarios evaluated – CFI has the option of choosing 

either . 

Scenario A – SO2 emissions are reduced from the “A” SAP 250 lb/hr to 75.8 lb/hr 

(24-hr average), from the “B” SAP 233.3 lb/hr to 93.3 lb/hr, from the “C” SAP 

401.1 lb/hr to 303.3 lb/hr, and from “D” SAP 401.3 lb/hr to 303.3 lb/hr. 

Additional minor reductions in NOx and sulfuric acid mist are obtained from 

reductions in production. 

Scenario B – SO2 emissions are reduced from the “A” SAP 250 lb/hr to 81.3 

lb/hr, from the “B” SAP 233.3 lb/hr to 100 lb/hr, from the “C” SAP 401.1 lb/hr to 

241.7 lb/hr, and from “D” SAP 401.1 lb/hr to 241.7 lb/hr. Again, minor

with Rule 62-296.340(5)(a)1. or Rule 62-296.340(5)(a)2, Florida Administrative Code. 

These exemptions follow the U.S. EPA “model rule” criteria whereby BART-eligible 

sources located greater than 50 (or 100) km from any Class I area and having potential 

emissions of SO2+NOx+PM less than 500 (or 1000) tons is exempt. In making this 

determination, the PM emissions are speciated and an equivalent tonnage is calculated 

based on each species sulfate-equivalent extinction.
