Tallahassee, Florida 32399-2400 

Dear Mr. Halpin: 

Thank you for submitting the state of Florida's 201 1 annual ambient air monitoring network plan 

(Network Plan) dated May 201 1. The Network Plan is required by 40 Code of Federal Regulations 

(CFR) 5 58.10. 

The U.S. Environmental Protection Agency Region 4 understands that the Florida Department of 

Environmental Protection and its local agencies provided the public a 30-day review period and received 

no comments. According to 40 CFR 5 58.lO(a)(2), since public inspection and comments have already 

been solicited, the EPA is not required to offer another comment period. 

Based upon our review of the Network Plan, EPA Region 4 has determined that the plan satisfies the 

applicable requirements of 40 CFR Part 58 and, by this letter, is approving the Florida Network Plan. In 

preparation for the 2012 Network Plan, EPA Region 4 is enclosing comments regarding the plan and 

information regarding network upgrades that will be needed in order to address sulfur dioxide 

monitoring requirements that become effective on January 1,20 13. 

Thank you for working with us to monitor air pollution and promote clean air in Florida. If you have any 

questions or concerns, please contact Doug Neeley at (404) 562-9097 or Daniel Garver at (404) 562- 

9839. 

Sincerely, 

Gwendolyn Keyes Fleming 

Administrator

regulatory requirements that address network plans, data certification, and minimum monitoring 

requirements, among other requirements, are found in 40 CFR Part 58. Minimum monitoring 

requirements for criteria pollutants are listed in 40 CFR Part 58, Appendix D. New national ambient air 

quality standards (NAAQS) were promulgated this year for carbon monoxide (CO), with minimum 

monitoring requirements effective January 1,201 5 and January 1,201 7. Minimum monitoring 

requirements are also listed for ozone (Os), particulate matter less than 2.5 microns (PM2.5), particulate 

matter less than 10 microns (PMlo), nitrogen dioxide (NO2), sulfur dioxide (SO2), and lead (Pb). 

The minimum monitoring requirements are based on core based statistical area (CBSA) boundaries as 

defined by the U.S. Office of Management and Budget (OMB), July 1,2009, population estimates fiom 

the U.S. Census Bureau, and historical ambient air monitoring data. Minimum monitoring requirements 

for 03, PM2.5, PMlo, only apply to metropolitan statistical areas (MSAs), which are a subset of CBSAs. 

OMB currently defines 30 CBSAs in the State of Florida. These CBSAs and the respective July 1,2009, 

population estimates fiom the U.S. Census Bureau are shown in Table 1. Please note that EPA is using 

the July 1,2009 population estimates because 201 0 census data aggregated by CBSA is not available for 

all areas at the time of this review.

Ozone Monitoring Requirements 40 CFR Part 58, Appendix D, Table D-2 

The State of Florida's proposed O3 monitoring network meets the minimum requirements found in 40 

CFR Part 58, Appendix D, Table D-2 for all MSAs. The proposed O3 monitoring network described in 

the Network Plan meets all of the design criteria of 40 CFR Part 58. 

Sulfur Dioxide (SO2) Monitoring Requirements 

40 CFR Part 58, Appendix D, 4.4 

Ambient air monitoring network design criteria for SO2 are found in Section 4.4 of Appendix D to 40 

CFR Part 58. This section requires that "The population weighted emissions index (PWEI) shall be 

calculated by States for each core based statistical area (CBSA). . ." As a result, the SOz monitoring 

site(s) required in each CBSA will satisfy minimum monitoring requirements if the monitor(s) is sited 

within the boundaries of the parent CBSA and is of the following site types: population exposure, 

maximum concentration, source-oriented, general background, or regional transport. An SO2 monitor at 

a NCore station may satisfy minimum monitoring requirements if that monitor is located within a CBSA 

with minimally required monitors under Appendix D, 4.4. 

To meet these requirements, FDEP is proposing new SO2 sites in the Bradenton-Sarasota-Venice, 

Lakeland-Winter Haven, and Homosassa Springs CBSAs. The SO2 network is to be operational 

beginning January 1,201 3. The SO2 monitoring network design proposed in the Network Plan meets the 

minimum requirements under 40 CFR Part 58. 

PMlo Monitoring Requirements 40 CFR Part 58, Appendix A, 3.3.1 

40 CFR Part 58, Appendix D, Table D-4 

The State of Florida's current PMlo monitoring network meets the minimum requirements found in 40 

CFR Part 58, Appendix D, Table D-4 for all MSAs. Also, all PMlo collocation requirements for manual 

methods found in 40 CFR Part 58, Appendix A, Section 3.3.1 are currently being met. Fifteen percent of 

each network of manual PMlo methods (at least one site) must be collocated. These collocation 

requirements are assessed at the primary quality assurance organization (PQAO) level. The State of 

Florida and all of its local agencies operate under a single PQAO (FDEP). The PMlo monitoring 

network described in the Network Plan meets all of the design criteria of 40 CFR Part 58. 
network of manual PM2.5 methods (at least one site) must be collocated. The PM2.5 monitoring network 

described in the Network Plan meets all of the design criteria of 40 CFR Part 58. 

FDEP also submitted a letter dated April 20,201 1 requesting a waiver of collocated monitor distance 

requirement for the Royal Palm Beach site (AQS ID: 12-099-0009). 40 CFR Part 58 Appendix A 

3.2.5.6 states that "the two collocated monitors must be within 4 meters of each other.. ." FDEP is 

requesting a waiver of this requirement because this site operates a continuous Federal Equivalent 

Method (FEM) that is housed in a trailer, and collocated manual Federal Reference Methods (FRMs) on 

the ground. EPA agrees that meeting this requirement is logistically infeasible at this site, and approves the site to continue operating in the current arrangement. 

PM2.5 Continuous Monitoring Requirements 

40 CFR Part 58, Appendix D, 4.7.2 Regulatory requirements for continuous PM2.5 monitoring require that ". . .State, or where appropriate, 

local agencies must operate continuous PM2.5 analyzers equal to at least one-half (round up) the 

minimum required sites listed in Table D-5 of this appendix. At least one required continuous analyzer 

in each MSA must be collocated with one of the required FRMREWARM [Approved Region'al 

Method] monitors, unless at least one of the required FRMREWARM monitors is itself a continuous 

FEM or ARM monitor in which case no collocation requirement applies." These minimum continuous 

PM2.5 monitoring requirements are currently met in the all of the MSAs in the State. Also, the 

continuous PM2.5 collocation requirements are currently met in all MSAs. Therefore, the continuous 

PM2.5 monitoring network described in the Network Plan meets all of the design criteria of 40 CFR Part 

58. 

PM2.5 Background and Transport Sites 

40 CFR Part 58, Appendix D, 4.7.3 40 CFR Part 58, Appendix D, 4.7.3 requires that "each State shall install and operate at least one PM2.5 site to monitor for regional background and at least one PM2.5 site to monitor for regional transport." 

The Network Plan identifies the Interagency Monitoring for Protected Visual Environments (IMPROVE) PM2.5 sites at the St. Mark's National Wildlife Refuge (AQS ID: 12-129-0001) and the 

Everglades National Park (AQS ID: 12-086-0030) as background sites and the IMPROVE PM2.5 site at 

the Chassahowitzka National Wildlife Refuge (AQS ID: 12-01 7-9000) as a transport site. Therefore, 

FDEP has satisfied the requirements of 40 CFR Part 58 for background and transport sites. 
monitor for Pb at urban NCore sites. Pb monitoring at NCore sites is required to begin on December 27, 

201 1. 40 CFR Part 58, Appendix D, 4.5 requires that "At a minimum, there must be one source-oriented 

SLAMS [State and Local Air Monitoring Station] site located to measure the maximum Pb 

concentration in ambient air resulting fiom each non-airport Pb source which emits 0.50 or more tons 

per year and fiom each airport which emits 1.0 or more tons per year.. ." Currently, monitoring is 

ongoing as required near Envirofocus Technologies Inc. in Tampa. In addition, FDEP is involved in 

negotiations with Volusia County to establish a required site at Daytona Beach International Airport. 

In its Network Plan, FDEP has requested that EPA grant a waiver of source-oriented Pb monitoring 

requirements for several sources. Section 4.5(a)(ii) of Appendix D to 40 CFR Part 58 provides the 

following provisions for a waiver of the Pb monitoring requirements: 

"(ii) The Regional Administrator may waive the requirement in paragraph 4.5(a) for monitoring 

near Pb sources if the State or, where appropriate, local agency can demonstrate the Pb source 

will not contribute to a maximum Pb concentration in ambient air in excess of 50% of the 

NAAQS (based on historical monitoring data, modeling, or other means). The waiver must be renewed once every 5 years as part of the network assessment required under 58.1 O(d)." 

FDEP has submitted air modeling indicating that the following sources will not contribute to a 

maximum Pb concentration in the ambient air in excess of 50% the NAAQS: 

Florida Power Corporation Solid Waste Authority of Palm Beach County 

Crystal River Energy Complex West Palm Beach, FL 

Crystal River, FL 

JEA Northside Generating Station Seminole Electric Cooperative, Inc. 

Jacksonville, FL Palatka, FL 

Tampa Electric Company 

Big Bend Power Station 

Apollo Beach, FL 

EPA has reviewed this information and concurs that the Pb emissions fiom each of these sources will 

not contribute to a maximum Pb concentration in the ambient air in excess of 50% of the NAAQS. 

Therefore, EPA is granting a waiver of the source-oriented ambient air monitoring requirements at these 

sources. The waivers must be renewed once every five years as part of the network assessment required 

under 40 CFR $58.1 O(d). 
EPA has reviewed this information, and concurs that the actual Pb emissions from this source are below 

0.50 tpy. Therefore, ambient air monitoring is not required at this source. 

FDEP also requested monitoring waivers for two additional sources in its Network Plan based on 

modeling. However, the actual Pb emissions for these sources in the 2008 National Emissions Inventory 

(NEI), version 1.5 are below 0.50 tpy, so monitoring is not required for these sources: 

Gulf Power Coinpany Pensacola, FL 

Stanton Energy Center 

Orlando, FL 

The Pb monitoring network described in the Network Plan meets all of the design criteria of 40 CFR 

Part 58. 

Operating Schedules 

40 CFR 8 58.12 

The monitoring network proposed in the Network Plan meets the required operating schedules for all 

continuous analyzers and all manual Pb, PM2.*, PMlo, PMlO-2.5, and PM2.5 Speciation Trends Network 

(STN) monitors. The sampling frequency of the two STN samplers at sites AQS ID:. 12-01 1-0034 and 

AQS ID: 12-057-3002 is listed as 1-in-6 days, but FDEP has stated that this is a typographical error and 

that the sites will continue to operate on a 1 -in-3 days schedule as required by 40 CFR 5 58.12(d)(3). 

FDEP has agreed to correct this error in AQS. 

FDEP also proposed to change the sampling frequency of the PM2.5 monitor at AQS ID: 12-099-2005 

from daily to 1 -in-3 days sampling. This proposed sampling frequency will meet the PM2.5 operating 

schedule requirements under 40 CFR 5 58.12(d). Therefore, EPA approves the change to 1-in-3 days at 

this site. 

Air Quality Index (AQI) Reporting 

40 CFR fj 58.50 

AQI reporting is required in MSAs with populations over 350,000. There are 12 MSAs in the State of 

Florida required to report an AQI: Miami-Fort Lauderdale-Pompano Beach, Tampa-St. PetersburgClearwater, Orlando-Kissimrnee, Jacksonville, Bradenton-Sarasota-Venice, Cape Coral-Fort Myers, 

Lakeland-Winter Haven, Palm Bay-Melbourne-Titusville, Deltona-Daytona Beach-Ormond Beach, 

Pensacola-Ferry Pass-Brent, Port St. Lucie, and Tallahassee. The Network Plan includes a link on Page 

7 to the FDEP website where this information is available. This satisfies the AQI reporting 

requirements.

According to 40 CFR $ 58.14(c), a request for discontinuation of a SLAMS monitor will be approved if 

the monitor meets any of the criteria under 40 CFR $ 58.14(c)(l) through (6). The following requested 

monitors meet the requirement of 40 CFR $ 58.14(c)(l): AQS ID: 12-01 1-003 1 NO2, AQS ID: 12-099- 

3004 SO2, AQS ID: 12-009-0011 PMlo, and AQS ID: 12-1 05-001 0 PMlo. All of these monitors have 

shown attainment of the respective NAAQS during the previous five years and have a probability of less than 10 percent of exceeding 80 percent of the applicable NAAQS during the next three years. 

Therefore, these SLAMS monitors are approved for discontinuation. 

The following monitors proposed for discontinuation are special purpose monitors (SPM): AQS ID: 12- 

099-0008 PM2.5 and AQS ID: 12-009-001 1 continuous PM2.5 and SO2. Discontinuation of these 

monitors is not subject to approval of the Regional Administrator under 40 CFR $58.14 because they 

are not SLAMS monitors. 

FDEP also proposes to change the monitor type of two Os sites in the Bradenton-Sarasota-Venice MSA, 

AQS IDS: 12-1 15-1006 and 12-1 15-2002. There are currently six SLAMS O3 monitors in the MSA and 

only two are required to be operated under 40 CFR Part 58 Appendix D. Also, the two monitors 

proposed to change monitor types have the two lowest historical design values of all monitors in the 

MSA. For these reasons, EPA approves changing these SLAMS monitors to SPMs. 

The minimum monitoring requirements found in Appendix D to 40 CFR Part 58 will continue to be met 

for the respective CBSAs after these network changes are made. Therefore, EPA approves the 

discontinuation, relocation, or monitor type change of all of the monitors listed in Table 2 above. 

FDEP has also proposed several new SLAMS sites in the Network Plan. EPA requests that these sites 

be submitted for final approval once site locations have been secured.
