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

Gainesville Regional Utilities (GRU) Deerhaven – Exemption Report

Introduction 

The GRU Deerhaven BART-eligible source was determined to be exempt based on modeling of PM 

emissions only in the August 2010 regional haze SIP submittal. The BART-eligible source consists of one 

75 MW oil/gas-fired boiler (boiler 1, emissions unit ID 3). The modeling for this exemption was 

completed by the source based on the VISTAS modeling protocol. 

This facility relied on the Clean Air Interstate Rule (CAIR) to satisfy the BART requirement for SO2 and 

NOx. With CAIR no longer applicable, GRU has reevaluated the exemption modeling by including all 

three visibility-impairing pollutants SO2, NOx, and PM. The CALPUFF model was used to determine if 

the BART-eligible source could meet the modeling exemption based on having a less than 0.5 desiview 

impact on any Class I area. The GRU followed their original approved protocol (based on the general 

VISTAS modeling protocol) to complete this analysis, with the following exceptions:

1. The current regulatory version of the CALPUFF modeling system is being used.

2. The FLM-derived meteorological input data set for 2001-2003 is being used, in lieu of the 

original VISTAS dataset. 

3. The maximum actual 24-hour average emission rates for SO2 and NOx are included and are 

derived from the most recent three years (2009-2011) of CEMS data for each unit. 

Results

The GRU Deerhaven facility is located within 300 km of four Class I areas: 91 km from Okefenokee NWA, 

113 km from Chassahowitzka NWA, 158 km from St. Marks NWA, and 200 km from Wolf Island NWA. 

The new IMPROVE algorithm was used to establish the 98th percentile change (8th high value) in visibility 

for each Class 1 area and for each year. A value less than 0.5 desiviews is deemed to be exempt from 

BART. As can be seen in the table below, the 8th high value is less than this value at all Class I areas and 

for all years. The source did not add in the NOx concentration for the purpose of determining the 

visibility degradation due to NO2, however, such an addition would not significantly change the results.

As such, DEP finds that the GRU Deerhaven BART-eligible source is exempt from BART.

Vero Beach Utilities – Exemption Report

Introduction  

In the original Florida SIP submittal Vero Beach utilities, units 2, 3, and 4, satisfied the modeling

exemption criteria by considering only the particulate matter (PM) emissions.  Units 2, 3, and 4 are

relatively small oil/gas‐fired boilers with generation capacities of 17 MW, 34 MW, and 56 MW,

respectively.  Unit 2 has not operated since 1999, and the other two units operate less than 8% of the

year.  The CALPUFF modeling used for establishing the exemption followed the protocol originally

submitted by the source operator.  This protocol was based on the general VISTAS modeling protocol

and was reviewed by DEP, EPA, and the FLM’s.    

This facility relied on the Clean Air Interstate Rule (CAIR) to satisfy the BART requirement for SO2 and

NOx.  With CAIR no longer applicable, the DEP has reevaluated the exemption modeling by including all

three visibility‐impairing pollutants SO2, NOx, and PM.  In completing this evaluation, the DEP followed

the original protocol with a few exceptions that we believe are appropriate.  These changes are:

1. The current regulatory version of the CALPUFF modeling system is being used.

2. The FLM‐derived meteorological input data set for 2001‐2003 is being used, in lieu of the

original VISTAS dataset.   

3. The maximum actual 24‐hour average emission rates for SO2 and NOx are included and are

derived from the most recent three years (2008‐1010) of CEMS data for each unit.  The original

PM emission rates were used based on maximum allowable limits.  

Further, where the original modeling modeled each unit separately and added the visibility impacts, the

new modeling simply modeled all three sources together.     

Results

The Vero Beach source is located within 300 kilometers of two Class 1 areas: Chassahowitzka National

Wilderness Area (247 km) and Everglades National Park (209 km).  The new IMPROVE algorithm was

used to establish the 98th percentile change (8th high value) in visibility for each Class 1 area and for each

year.   A value less than 0.5 desiviews is deemed to be exempt from BART.  As can be seen in the table

below, the 8th high value is less than this value at both Class 1 areas and for all years.   As such, DEP finds

that the Vero Beach  BART‐eligible source is exempt from BART.

FPL Putnam – Exemption Report

Introduction  

The FPL Putnam BART‐eligible source was determined to be exempt based on modeling of PM emissions

only in the August 2010 regional haze SIP submittal.  The BART‐eligible source consists of four

combustion turbines each with an associated heat recovery steam generator equipped with duct

burners identified as HRSG11, HRSG12, HRSG21, and HRSG22.  The modeling for this exemption was

completed by the VISTAS contractor TRC, Inc., using a conservative implementation of the VISTAS

modeling protocol.  A more specific modeling protocol following the VISTAS protocol was submitted by

FPL for the Putnam BART‐eligible source and included in the state’s SIP submission, but was not

implemented for the Putnam facility because the conservative TRC modeling had shown that it met the

exemption criteria.   

This facility relied on the Clean Air Interstate Rule (CAIR) to satisfy the BART requirement for SO2 and

NOx.  With CAIR no longer applicable, FPL has reevaluated the exemption modeling by including all three

visibility‐impairing pollutants SO2, NOx, and PM.  In fact, FPL had originally evaluated the Putnam BART‐

eligible source with the appropriate emissions for all three visibility impairing pollutants, and had

determined that it would meet the modeled exemption criteria.  This original modeling was not

submitted because it was unnecessary in lieu of the TRC results.  FPL has reproduced this modeling using

the approved modeling protocol and the emissions applicable at the time of the original submission.   

Correspondence with EPA Region 4 confirmed that the use of the original protocol modeling was

acceptable.  The DEP agrees since, had FPL submitted this analysis for the original SIP submittal, it would

have been acceptable and an exemption would have been granted.

Results

The FPL Putnam facility is located 119 km from Okefenokee NWA, 141 km from Chassahowitzka NWA,

and 236 km from St. Marks NWA.  The new IMPROVE algorithm was used to establish the 98th percentile

change (8th high value) in visibility for each Class 1 area and for each year.   A value less than 0.5

desiviews is deemed to be exempt from BART.  As can be seen in the table below, the 8th high value is

less than this value at both Class 1 areas and for all years.   As such, DEP finds that the FPL Putnam  

BART‐eligible source is exempt from BART.

Lake Worth Utilities –Exemption Report

Introduction

The Lake Worth Utilities Tom G. Smith BART‐eligible source consists of the 27 MW fossil fuel steam

generator 3 (S3) and the 30 MW gas turbine 1 (GT1).  This source was originally determined to be

exempt from BART following the model rule exemption, having less than 1000 tons of PM emissions and

being more than 100 kilometers from the nearest Class I area.   With CAIR being replaced by CSAPR, and

with Florida no longer subject to CSAPR for the purpose of SO2 emissions, the model rule exemption

must apply to the total of SO2, NOx, and PM emissions.  As a result, the Lake Worth BART‐eligible source

does not satisfy the exemption criteria of the model rule exemption.   

In lieu of the model rule exemption, the DEP has evaluated the Lake Worth BART‐eligible source for

meeting the modeling exemption based on having a less than 0.5 desiview impact on any Class I area

using the CALPUFF model.  The DEP followed the general VISTAS modeling protocol to complete this

analysis, with the following exceptions:

1. The current regulatory version of the CALPUFF modeling system is being used.

2. The FLM‐derived meteorological input data set for 2001‐2003 is being used, in lieu of the

original VISTAS dataset.   

3. The maximum actual 24‐hour average emission rates for SO2 and NOx are included and are

derived from the most recent three years (2008‐1010) of CEMS data for each unit.  The PM

emission rates were used based on maximum allowable limits.

Results

The Lake Worth source is located within 300 km of one Class I area: the Everglades National Park (106

km).  The new IMPROVE algorithm was used to establish the 98th percentile change (8th high value) in

visibility for each Class I area and for each year.   A value less than 0.5 desiviews is deemed to be exempt

from BART.  As can be seen in the table below, the 8th high value is less than this value at both Class 1

areas and for all years.   As such, DEP finds that the Lake Worth BART‐eligible source is exempt from

BART.

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 specie’s sulfate-equivalent extinction.
