Dear Mr. Green: 

Thank you for submitting the State of Florida's 2015 annual ambient air monitoring network plan 

(Network Plan) dated May 2015. The Network Plan is required by 40 Code of Federal Regulations 

(CFR) § 58.10. The Network Plan covers the ambient air monitoring network operated by the Florida 

Department of Environmental Protection (FDEP) and the local air quality agencies in Florida. 

The U. S. Environmental Protection Agency Region 4 understands that FDEP provided the public a 30-

day review period and received no comments. According to 40 CFR § 58.10(a)(2), since public 

inspection and comments have already been solicited, the EPA is not required to offer another comment 

period. 

The EPA approves the State's 2015 Network Plan with the exception of the proposals for three 

monitoring sites. As we have discussed, once you have all the information needed for full evaluation of 

these proposed sites (two near-road monitoring sites and one source-oriented S02 site) we will review 

and respond to your request as discussed in the enclosure. After we have reached an agreement with the 

proposed locations for these sites, the state will need to make that information available for public 

inspection. Upon completion of the public inspection process, an addendum to the Network Plan will 

need to be submitted to the EPA Region 4 for approval. 

We have enclosed comments on the Network Plan and details of our review. 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 Gregg Worley at (404) 562-9141 or Daniel Garver at (404) 562-9839. 

Sincerely,

2015 State of Florida Ambient Air Monitoring Network Plan 

U.S. EPA Region 4 Comments and Recommendations 

This document contains U.S. EPA Region 4 comments and recommendations on the state of Florida's 

2015 ambient air monitoring network plan (Network Plan). Ambient air monitoring rules, which include 

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. Minimum monitoring 

requirements are listed for ozone (OJ), particulate matter less than 2.5 microns (PM2.s), particulate 

matter less than 10 microns (PMto), nitrogen dioxide (N02), sulfur dioxide (SOz), carbon monoxide 

(CO), and lead (Pb). 

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

defmed by the U.S. Office of Management and Budget (OMB), July 1, 2014, population estimates from 

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

for OJ, PM2.s, and PM to, only apply to metropolitan statistical areas (MSAs), which are a subset of 

CBSAs. OMB currently defines 29 CBSAs in the state of Florida. These CBSAs and the respective July 

1, 2014, population estimates from the U.S. Census Bureau are shown in Table I.

In the Network Plan, FDEP has proposed several new monitoring sites. The Daniela Banu NCore site in 

Broward County, the St. Marks NCore site, and the Orlando 1-4 near-road site have been approved by 

EPA in previous Network Plans. The remainder of the Network Plan changes will require FDEP to 

submit additional information before they can be approved. FDEP is requesting to submit final proposals 

for these proposed network additions or discontinuations that include all of the information required for 

approval by 40 CFR §58.10(b) or §58.14, as applicable. Once EPA Region 4 and FDEP are in 

agreement about the details of these sites, the proposals should be submitted as an addendum to the 2015 

Network Plan or as part of the 2016 plan, and should be made available for public inspection before 

submittal to EPA for approvaL The following three proposed sites must begin operating in order for the 

FDEP monitoring network to meet minimum requirements: the MDX near-road site in Miami-Dade 

County, the Sawgrass Lake Parkway near-road site in Pinellas County, and the source-oriented S02 site 

near the Duke Energy Crystal River Steam Plant in Citrus County. A summary of the monitoring 

network changes proposed by FDEP~ and EPA's responses are provided in Table 2.

FDEP has also proposed to change the monitoring objective for several PM2.s and OJ sites in its network 

from population exposure to high concentration. EPA understands that FDEP is making these changes in 

conjunction with its network assessment, and has identified these sites as high concentration based on 

analysis of several factors including historical data, local emissions, and meteorology. EPA approves the 

monitoring objective changes proposed in the Network Plan. 

Operating Schedules 

40 CFR § 58.12 

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

continuous analyzers and all manual Pb, PM 10, PM2.s. and PM2.s Speciation Trends Network (STN) 

monitors. FDEP has not proposed any changes to its operating schedules in the Network Plan. 

Air Quality Index (AQI) Reporting 

40 CFR § 58.50 

5 
AQI reporting is required in MSAs with populations over 350,000. There are 12 MSAs in the state that 

are required to report an AQI: Miami-Fort Lauderdale-West Palm Beach, Tampa-St. PetersburgClearwater, Orlando-Kissimmee-Sanford, Jacksonville, North Port-Sarasota-Bradenton, Cape Coral-Fort 

Myers, Lakeland-Winter Haven, Deltona-Daytona Beach-Ormond Beach, Palm Bay-MelbourneTitusville, Pensacola-Ferry Pass-Brent, Port St. Lucie, and Tallahassee. The Network Plan includes a 

link on Page 10 to the FDEP website where this information is available. The AQI reporting 

requirements are currently being met. 

National Core (NCore) Monitoring Network 

40 CFR Part 58 Appendix D, 3.0 

FDEP has designated three NCore sites: Sydney Road in Tampa (AQS ID: 12-057-3002), Daniela Banu 

in Broward County (AQS ID: 12-011-0034). and St. Marks National Wildlife Refuge (AQS ID: 12-129-

0001). These sites satisfy the requirements for NCore monitoring and have been approved by the EPA's 

Office of Air Quality Planning and Standards. The St. Marks NCore site was established in 2014 as a 

rural NCore site.

The stmc nf Florida's proposed 0 3 monitoring network meets the minimum requirements found in 40 

CFR Pn·· \ r p ·dix D, Table D-2 for all MSAs. Additionally, the proposed 03 monitoring network 

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

CO Monitoring Requirements 

40 CFR J>art 58, Appendix D, 4.2 

Beginning January 1, 2015, CO monitoring was required at near-road monitoring sites in CBSAs with 

populations greater than 2,500,000. CO monitoring will be required at a near-road monitoring site in 

CBS As with populations greater than 1,000,000 beginning on January 1, 2017. The Network Plan 

indicates that CO monitoring is ongoing at the Hillsborough County near-road site in the Tampa-St. 

Petersburg·Clearwater CBSA, and the Broward County near-road site in the Miami-Fort LauderdaleMiami Beach CBSA. Therefore, the CO monitoring network described in the Network Plan meets all of 

the design criteria of 40 CFR Part 58. 

N02 Monitoring Requirements 

40 CFR Part 58, Appendix D, 4.3 

Ambient air monitoring network design criteria for N02 are found in Section 4.3 of Appendix D to 40 

CFR Part 58. Three types of N02 monitoring are required: near-road, area-wide, and Regional 

Administrator. These types of N02 monitoring are described in sections 4.3.2, 4.3.3, and 4.3.4, 

respectively. 

Ambient air monitoring design criteria for near-road N02 monitoring sites are found in section 4.3.2 of 

Appendix D to 40 CFR Part 58. Near-road monitoring stations are currently operating in the following 

6 
CBSAs: Tampa-St. Petersburg-Clearwater (in Hillsborough County), Miami-Fort Lauderdale-West Palm 

Beach (in Broward County), and Jacksonville. The Network Plan also includes proposed near-road sites 

in the following CBSAs: Tampa-St. Petersburg-Clearwater (in Pinellas County), Miami-Fort 

Lauderdale-West Palm Beach (in Miami-Dade County}, and Orlando-Kissimmee-Sanford (in Orange 

County). The Orlando near-road site was previously approved as part of the 2014 Network Plan. 

Second near-road monitoring sites were required to begin operation on January 1, 2015 in the MiamiFort Lauderdale-West Palm Beach and Tampa-St. Petersburg-Clearwater CBSAs. New sites in MiamiDade County and Pinellas County are proposed in the Network Plan to meet these requirements, but 

more information about these sites is required for approval. Once the details of these sites are finalized, 

the state will need to submit an addendum to the Network Plan containing these site proposals. The 

addendum must include all of the required information for proposed sites under 40 CFR §58.1 O(b ), and 

should also include additional information about the proposed near-road monitoring sites. Section 13.5 

of the near-road N02 Technical Assistance Document (TAD) 1 and Table 13.1 of the TAD discuss 

important site and road parameters when evaluating a near-road site. Using the TAD as a reference, 

additional information provided on near-road NOz monitoring should include, at minimum, the 

following information for each site: 

• Proposed AQS ID 

• Street address and site geographical coordinates (longitude and latitude) 

• Target road segment description including type of road 

• Site pictures facing 4-8 directions- N, S, E, W, NE, NW, SE, SW 

• Probable distance between the inlet probe and the outside nearest edge of the target road 

• Probable probe height of the inlet probe from ground level 

• Site property description including property owner and feasibility of site access 

• Roadway design and configuration 

• Presence of any roadside structures 

• Nearest wind rose representative of the site and orientation of the site with respect to the 

predominate wind direction 

• Traffic data and ranking information (see Table 6-3 of the Technical Assistance Document), as 

well as the source and vintage of the data 

• Sampling and analysis method(s) for each measured parameter 

• Operating schedules for each monitor at the site 

• Monitoring objective and spatial scale of representativeness for each monitor at the site. 

• MSA, CBSA, CSA or other area represented by the monitor 

• Other evidence that siting criteria are being met, including measurements to any nearby 

obstructions or trees. 

Once EPA Region 4 is in agreement with the proposed near-road sites, the state will need to make the 

information available for public inspection. Upon completion of the public inspection process, the 

Network Plan addendum will need to be submitted to EPA Region 4 for approval. We will continue to

work with your agency as needed to facilitate the establishment of these sites as expeditiously as 

possible. 

Section 4.3.2 of Appendix D to 40 CFR Part 58 also requires CBSAs with populations between 500,000 

and 1,000,000 people to operate a near-road NOz monitor starting in January 1, 2017. Florida has five 

CBSAs with populations in this range: North Port-Sarasota-Bradenton, Cape Coral·Fort Myers, 

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

As a result of the 5-year NAAQS review cycle, the NOz monitoring requirements may be modified in 

2016. The N02 near-road monitoring requirements may change for CBSAs with populations between 

500,000 and 1,000,000 people, such as the Florida CBSAs listed above. 

Ambient air monitoring network design criteria for area-wide N02 sites are found in section 4.3.3 of 

Appendix D to 40 CFR Part 58. The area-wide NOz monitoring network described in the Network Plan 

meets the requirements of Section 4.3.3 in all areas. These sites are summarized in Table 3.

Ambient air monitoring network design criteria for Regional Administrator required NOz monitoring, 

often referred to as RA-40 monitoring, are found in section 4.3.4 of Appendix D to 40 CFR Part 58. 

Under these provisions Regional Administrators must require a minimum of 40 additional NOz 

monitoring stations nationwide, with a primary focus on siting these monitors in locations to protect 

susceptible and vulnerable populations. EPA and FDEP have previously identified the monitor at the 

Coral Reef site (AQS ID: 12-086-0031) in Miami-Dade County as required under Section 4.3.4. The full 

list of NOz monitors identified by the Regional Administrators can be found on EPA's website at 

http://www .epa.gov /ttnamti 1/<; vpop.html. 

S02 Monitoring Requirements 

40 CFR Part 58, Appendix D, 4.4 

Ambient air monitoring network design criteria for SOz 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) .. . " The S02 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 type(s): population exposure, maximum 

concentration, source-oriented, general background, or regional transport. An SOz monitor at an NCore 

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

required monitors under Appendix D, 4.4. 

8 
FDEP is proposing a new site in the Homosassa Springs CBSA to meet the PWEI requirement (AQS ID: 

12-017-0006). However, the Network Plan does not include all of the required information about this 

site for approval. FDEP will need to submit an addendum to the Network Plan that contains a full 

proposal for this site. The addendum must include all of the required information for proposed sites 

under 40 CFR §58.10(b). The addendum should also include supporting information about how the site 

location was selected, such as site photos, maps, wind roses, and information about the target source 

including any air modeling that was conducted to inform the site selection. The addendum should be 

made available for public inspection under40 CFR § 58.10(a)(l), and then submitted to EPA Region 4 

for approval. All other applicable CBSAs in Florida are now meeting the requirements for S02 PWEI 

monitoring. 

EPA finalized the S02 Data Requirements Rule (DRR) (see 80 Federal Register, No. 162) on August, 

21, 2015. This rule will require characterization of the air quality near sources with S02 emissions 

greater than 2,000 tons per year by conducting ambient air monitoring or modeling. We encourage your 

agency to begin having conversations with affected sources in your state to determine an agreed upon 

approach for meeting the DRR requirements. By January 15, 2016, FDEP must submit a final list to 

EPA Region 4 identifying the sources in the state around which S02 air quality must be characterized. 

For sources that FDEP decides to evaluate using ambient air monitoring, new site proposals must be 

included in the 2016 Network Plan. The location of these monitoring sites should be selected using the 

process outlined in the S02 NAAQS Designations Source-Oriented Monitoring Technical Assistance 

Document2. 

Pb Monitoring Requirements 

40 CFR Part 58, Appendix D, 4.5 

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 from each non-airport Pb source which emits 0.50 or more tons per year and 

from each airport which emits 1.0 or more tons per year ... " Monitoring is ongoing as required near 

Envirofocus Technologies Inc. in Tampa. 

FDEP has also submitted revised Pb emissions for one facility that had emissions greater than 0.5 tons 

per year in the 2011 National Emissions Inventory: IFF Chemical Holdings, Inc. in Jacksonville. EPA 

accepts these revised emissions calculations, and agrees that the actual Pb emissions from this source are 

below 0.5 tons per year. Therefore, Pb monitoring is not required near this source. 

40 CFR Part 58, Appendix D, 3(b) requires that "NCore sites in CBSA with a population of 500,000 

people (as determined in the latest Census) or greater shall also measure Pb either as Pb-TSP or PbPMJO." The Network Plan indicates that Pb-PMw sampling is ongoing at the Tampa NCore site (AQS 

ID: 12-057-3002) and will begin at the Broward County NCore site (AQS ID: 12-011-0034) soon. The 

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

PMto Monitoring Requirements 

40 CFR Part 58, Appendix A, 3.3.1 

40 CFR Part 58, Appendix D, 4.6 and Table D-4 

The state of Florida's PMw monitoring network meets the minimum requirements found in 40 CFR Part 

58, Appendix D, Table D-4 for all MSAs. Also, all PM to collocation requirements for manual methods 

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

manual PM to 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 PM to monitoring network described in the Network 

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

PMz.s Monitoring Requirements 

40 CFR Part 58, Appendix A, 3.2.5 

40 CFR Part 58, Appendix D, 4. 7 and Table D-5 

The state of Florida's PM2.s monitoring network meets the minimum requirements found in 40 CFR Part 

58, Appendix D, Table D-5 for all MSAs. Also, all PM2.s collocation requirements found in 40 CFR Part 

58, Appendix A, Section 3.2.5 are being met. Fifteen percent of each network of manual PM2.s methods 

(at least one site) must be collocated. 

Beginning January 1, 2015, PM2.s monitoring is required at near·road monitoring sites in CBS As with 

populations greater than 2,500,000. PM2.s monitoring will be required at a near-road monitoring site in 

CBS As with populations greater than 1,000,000 beginning on January 1, 2017. The Network Plan 

indicates that PM2.s monitoring is ongoing at the Hillsborough County near-road site in the Tampa-St. 

Petersburg-Clearwater CBSA, and at the Broward County near-road site in the Miami-Fort LauderdaleMiami Beach CBSA. The PM2.s monitoring network described in the Network Plan meets all of the 

design criteria of 40 CFR Part 58. 

PM2.s Continuous Monitoring Requirements 

40 CFR Part 58, Appendix D, 4. 7.2 

Regulatory requirements for continuous PM2.s monitoring require that ..... State, or where appropriate, 

local agencies must operate continuous PM2.s 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 FRMIFEM/ARM [federal reference 

method/federal equivalent method/approved regional method] monitors, unless at least one of the 

required FRMIFEM/ ARM monitors is itself a continuous FEM or ARM monitor in which case no 

collocation requirement applies: · These minimum continuous PM2.s monitoring requirements are met in 

the all of the MSAs in the state. Also, the continuous PM2.s collocation requirements are met in all 

MSAs. Therefore, the continuous PM2.s monitoring network described in the Network Plan meets all of 

the design criteria of 40 CFR Part 58. 

PM2.s Background and Transport Sites 

40 CFR Part 58, Appendix D, 4. 7.3 

10 
40 CFR Part 58, Appendix D, 4.7.3 requires that "each state shall install and operate at least one PM2.s 

site to monitor for regional background and at least one PMz.s site to monitor for regional transport." 

The Network Plan identifies the Interagency Monitoring for Protected Visual Environments 

(IMPROVE) PM2.s 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.s site at 

the Chassahowitzka National Wildlife Refuge (AQS ID: 12-017-9000) as a transport site. Therefore, 

FDEP has satisfied the requirements of 40 CFR Part 58 for background and transport sites. 

P~b.s Continuous Federal Equivalent Methods 

40 CFR § 58.10(e) 

EPA regulations contain provisions for handling data collected using continuous PM2.s FEMs. These 

procedures are found at 40 CFR § 58.1 0( e). If an agency can demonstrate that the FEM data are not of 

sufficient comparability to a collocated FRM, then the monitoring agency may request that the FEM 

data not be used in comparison to the NAAQS. In the Network Plan, FDEP has requested to maintain 

the NAAQS exclusion for its continuous PMz.s FEMs operated at two Palm Beach County sites (AQS 

IDs: 12-099-0008 and 12-099-0009). EPA has reviewed the information submitted in the Network Plan, 

and approves these monitors for exclusion from NAAQS comparisons. 

PM2.s Chemical Speciation Network 

EPA conducted an assessment of the PM2.s Chemical Speciation Network (CSN) in an effort to optimize 

the network and create a network that is sustainable going forward. As a result of this assessment, EPA 

defunded a number of monitoring sites, and at all sites eliminated the CSN PM25 mass measurement, 

reduced the frequency of carbon blanks, reduced sample frequency at some monitoring sites, and 

reduced the number of icepacks in shipment during the cooler months of the year. As FDEP discusses in 

the Network Plan, EPA defunded the Skyview site (AQS ID: 12-103-0026) as of January 2015. In 

addition, all of the state's CSN sites were impacted by the elimination of the PMz.s mass measurement, 

the reduction of carbon blank frequency, and the reduction in icepacks. 

Request for Waiver of Siting Criteria 

On Page 38 of the Network Plan, FDEP requests a waiver of the monitor siting criteria for the 

Woodlawn PM10 site in St. Petersburg. The site has been operating in its current location since 1992. 

Recent improvements at the park where the site is located included the planting of trees that resulted in 

the monitor no longer meeting siting criteria. 

Given the information and rationale provided by FDEP, EPA is open to considering this request for a 

waiver. However, more information will be needed for approval. Specifically, FDEP needs to identify 

which requirements in 40 CFR Part 58, Appendix E the site does not meet and thus are being requested 

by the state to be waived. Also, FDEP must provide current measurements or data, in the form of the 

relevant siting criteria requirements (e.g., measurements to trees or obstructions, etc.). 

ll 
Under 40 CFR Part 58, Appendix E, Section 10, waivers of siting criteria for new sites can be granted if 

either of the following criteria are met: 

10.1.1 The site can be demonstrated to be as representative of the monitoring area as it 

would be if the siting criteria were being met. 

1 0.1.2 The monitor or probe cannot reasonably be located so as to meet the siting 

criteria because of physical constraints (e.g., inability to locate the required type of site 

the necessary distance from roadways or obstructions). 

The additional information requested above may be submitted in a separate letter, or in an addendum to 

the 2015 Network Plan.
