FINAL REPORT- Destin Airport Page 3 of 39 6/19/2007 EXECUTIVE SUMMARY Tetra Tech, Inc., (Tt) was retained by the City of Destin to conduct an air monitoring sampling project of air impact of the Destin Airport in Dest in, Florida.

The airport is a publicly owned (by Okaloosa County ) general aviation airport with a 5,000 foot runway located to the east of downtown Destin, Flor ida. The objective of this sampling project as authorized by the City of Destin was to determin e if airport operations (plane side and ground side) can be confirmed and quantified by concurrent ambient air quality sampling at multiple sites in Destin, Florida.

The parameters evaluated in the sampling project in cluded organic compounds (total of 108), total suspended particulate matter (dust), and part iculate lead. Five sample sites where chosen for the sampling project with three sites adjacent to the airport and two sites that were classified in this sampling project as Destin City urban back ground. The sample sites are shown in the following chart.

Sampling was conducted over 12-hour periods using a high volume air sampler to collect particulate matter and particulate lead. Sampling was conducted over 10-hour periods using an evacuated Summa® canister with limiting orifice to collect organic compounds. Sampling was started Tuesday morning April 3, 2007 and completed Saturday evening April 7, 2007. A total of 35 particulate samples were collected and a tota l of 36 Summa® organic compound samples were collected. The additional organic compound sa mple was a “duplicate” sample to validate the analysis methodology. All samples were evaluat ed using approved US EPA analysis methods as discussed in more detail in the body of this report. DESTIN

FINAL REPORT- Destin Airport Page 4 of 39 6/19/2007 AIRPORT SAMPLING SCOPE DISCUSSION The airport sampling project was designed to provid e the following information to the City of Destin relative to the limited sampling project sco pe outlined below:

1. Determine the air concentration of chemicals and ch emical compounds that may indicate the presence of aviation fuel combustion or use; an d identify the air concentrations of
those substances at three locations around the Dest in Airport and two at other locations in Destin, Florida.

2. Evaluate the presence of particulate at each of the five sample locations and determine if there is any relation between the presence or absen ce of particulate matter and time of day, weather patterns, or sample site location.

3. Evaluate ambient air samples and report on any chem icals that were observed during this sampling project that exceed the odor threshold sta ndards at locations where air samples
were collected.

4. Conduct the sampling project within a budget fee of $31,500.

5. Evaluate the following hypothesis: Chemicals that a re an indicator of aircraft operations will be present in air samples collected near airpo rt operations during normal flight operation hours (day) and should not be present (or will be present at much lower concentrations) during hours of minimal flight oper ations (night).

The sampling project was not designed to address th e following issues:

1. Evaluate long term air quality based on multiple wi nd directions and multiple locations.

2. Evaluate health risks associated with pollutant lev els observed at the five locations.

3. Implementation of corrective action plans to mitiga te pollutant levels observed during this sampling project.

4. Conduct analysis of the particulate matter collecte d in the high volume samplers to determine size speciation of particulate matter, to identify the specific chemical species and makeup of the particulate collected (other than lead), or develop health based
conclusions related to the source or sources of the particulate matter collected.

5. Evaluate air concentrations of pollutants at each s ample station for the purpose of establishing compliance with regulatory standards.

6. Develop a comprehensive ambient air quality databas e for all criteria pollutants that have National Ambient Air Quality Standards (NAAQS). (N ote NAAQS includes particulate matter, oxides of nitrogen, sulfur dioxide, carbon monoxide, ozone, lead)

7. Quantify the relative levels of odor for gasoline, diesel, JetA, or AVGAS fuel that could be present in the ambient air under study and could be the result of airport operations.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 5 of 39 6/19/2007 AIRPORT IMPACT AREA VERSUS URBAN BACKGROUND AREA
The following figure identifies the three sample lo cations adjacent to the Airport (site 1, 2, and 3) and classifies them as “Potential Airport Impact Ar eas” (yellow shaded oval) and identifies the two sample locations remote from the airport (site 4 and 5) and classifies them as “Destin City Background” (green shaded oval). This sampling pro ject used the sample data values from sites 4 and 5 as the urban background to establish the De stin ambient air quality.

SAMPLING PROJECT FINDINGS
The following chart identifies the materials or com pounds that were detected in one or more samples collected at the five sampling station loca tions. There were 108 organic compounds analyzed by the TO-15 laboratory analysis method TO -15 and only eleven organic compounds were detected above the laboratory detection limit. This does not mean that the other 97 organic compounds were not present in the air samples, it o nly means that the levels of air concentration
for those 97 were below the level that the laborato ry could confirm by testing methods. In addition to the organics, the airport sampling proj ect evaluated the presence of particulate and particulate lead in order to evaluate the potential presence of these materials in air in the Destin

area.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

June 19, 2007

FINAL REPORT- Destin Airport Page 6 of 39 6/19/2007 The following organics were found only in the sampl e at the Harbor location: Isopropyl alcohol, Chlorodifluoromethane, and Propylene. These compou nds were not present in any other sample
and were therefore assumed to be the result of acti vities unique to the harbor and bay area and not associated with airport operations. They were not included in the TOTAL ORGANICS data used in this analysis.

Methylene chloride and hexane were found in only on e sample (Indigo Court with the wind out of the North). Since these two compounds typically are found in paint or solvent operations, it is assumed that their presence at this station with wi nd out of the north was not the result of airport operations since Indigo Court is directly north of the airport. These two compounds also were
not included in the TOTAL ORGANICS data used in thi s analysis.

The only other organic compound with one detected o ccurrence was carbon disulfide at the EMS station (south end of airport) on Tuesday PM when t here were variable winds. The source of this compound could be airport or mobile sources (auto o r truck). Since there was only one sample, this compound was not included in the TOTAL ORGANIC S data.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

June 19, 2007

FINAL REPORT- Destin Airport Page 7 of 39 6/19/2007 AIRPORT SAMPLING PROJECT IMPACT FINDINGS Airport sampling involved three steps. The first w as to develop a list of chemicals or materials that could predict airport operations. The second was to conduct air sampling at five sample locations the week of April 3, 2007. The third was to analyze these samples and determine the air concentrations in the air samples collected bet ween Tuesday AM and Saturday PM the week of April 3, 2007.

Air concentrations were analyzed for the following chemical markers assumed to be indicators of the use of AVGAS at the Destin Airport: Ethylene Di bromide, Tetra Ethyl Lead, and Lead Particulate. Neither ethylene bromide nor tetra et hyl lead was found in any air samples taken at any of the five sampling stations. Lead particulat e, several organic compounds, and total suspended particulate were found in one or more sam ples at each of the five sample locations. Impact of airport operations was evaluated at the f ive locations by comparing the levels of lead particulate, total suspended particulate (TSP) and organic compound concentrations to the levels of these substances at the sample station 4 and 5 ( urban background).

Meteorological data to show wind direction during e ach sample period was obtained from the hourly data summary obtained from the NOAA weather station data. This station is located on the Destin Airport. Wind direction was from the so uth during the first day of sampling. The impact areas for airport operations for the Tuesday AM and PM sampling are shown in the following chart:WIND DIRECTIONTUESDAY AM

FINAL REPORT- Destin Airport Page 9 of 39 6/19/2007 SAMPLING PROJECT HYPOTHESIS
The following hypotheses were analyzed in this samp ling project:
Hypothesis 1 Airport operations will result in high er air concentrations at sites close to the

airport versus sites remote from the airport
Hypothesis 2 There should be higher air concentrat ions at sites downwind from the airport

versus upwind of the airport for each specific weat her condition
Hypothesis 3 Airport operations will have little o r no impact on sites classified as city

background (Station 4 Buck Destin Park or Station 5 Harbor Road) unless those sites are directly downwind from airport operations

. Hypothesis 4 Airport operations during the daytime (7am to 7pm) will result in higher air

concentrations than nighttime operations (7pm to 7a m) due to more flight operation during the day

SAMPLING PROJECT VARIABLES
Data was collected at each sample site and was anal yzed for the sampling project based on the following variables:

1. Presence or absence of a contaminant at a sample si te

2. Concentration of contaminant at a sample site (assu mes presence at the sample site of data above the analytical detection method from the laboratory analysis)

3. AM versus PM

4. IMPACT by airport operations versus NO IMPACT from airport operations

5. WIND DIRECTON

Air samples were analyzed by Atmospheric Analysis a nd Consulting, Inc. and the detailed results of the air concentrations by sample are inc luded in Appendix 7 of this report. Summaries of the data by sample site are listed in Appendix 5 , Tables 3, 4, and 5 (for particulate matter, particulate lead, and total organic compounds respe ctively). The four hypothesis identified above were evaluated using the Microsoft® Office Ex cel data analysis program t-distribution analysis. The t-distribution statistical method id entifies the probability associated with a
Student's t-Test and is used to determine whether t wo samples are likely to have come from the same two underlying populations that have the same mean (or average).Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

The following nine charts show the relation of the sample results by station and by variable.

The urban background concentration of particulate i n the ambient air is based on the sample value average of 30.6 micrograms of total suspended particulate per cubic meter of air based on Station 4 (Buck Destin Park) and Station 5 (Harbor)

.

This chart compares two variables AIRPORT IMPACT ve rsus NO IMPACT. The following
lists the criteria for IMPACT versus NO IMPACT:
IMPACT by AIRPORT on a sample station was considere d if:

• Wind blowing TOWARD the sample station and airport operations UPWIND of station (Neither Station 4 or 5 were impacted by wind blowi ng from the airport toward those stations), or

• Variable wind conditions that were included in the IMPACT column for data comparison (See data tables in Appendix 5)Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

June 19, 2007

FINAL REPORT- Destin Airport Page 11 of 39 6/19/2007 NO IMPACT by AIRPORT on a sample station was consid ered if:

• Wind blowing TOWARD the sample station and airport operations DOWNWIND from station (Neither Station 4 or 5 were impacted by wi nd blowing from the airport toward those stations), or

• Variable wind conditions that were included in the IMPACT column for data comparison (See data tables in Appendix 5)

There were no wind conditions that did not result i n impact by airport operations on Station 1 Misty Way or Station 3 EMS station. Therefore, the re is no brown colored bar of NO IMPACT
data for those two stations. Station 2 did have sa mpling occur during a period classified as NO IMPACT; therefore, there is a double bar on the Sta tion 2 Indigo location for both observed
conditions.

The conclusion from the above chart is that for par ticulate, Station 1 and 3 are impacted above the urban background concentration (Station 4 and 5 ) but Station 2 was impacted less. From the limited data collected during this sampling program the particulate observed at station 2 was the same for IMAPCT versus NO IMPACT by airport operati ons and was in fact lower than the downtown and Harbor average for Destin background.

June 19, 2007

FINAL REPORT- Destin Airport Page 12 of 39 6/19/2007 The chart (4) above shows that for particulate lead , the three stations close to the airport show higher levels of lead concentration than the backgr ound at station 4 and 5. Since lead is one key
indicator of the use and combustion of AVGAS at the airport, the conclusion that can be drawn from the chart above is that lead is present above background levels around the airport when the wind conditions direct airport air toward the sampl e location.

To put the above values in perspective with regard to health risk, the average background for lead in the air samples was 2.5 nanograms per cubic meter. The EPA has established the national ambient air quality standard for lead in a ir of 1500 nanograms per cubic meter. Therefore, the lead content in the air in and aroun d Destin is much lower than the NAAQS
standards.

According the data from the US EPA EPCRA database f or toxic air emissions, lead and lead particulate is emitted into the air from Elgin Air Force Base. These emissions are documented in the FORM R report listed in Appendix 12. There has been no analysis to determine if sources of lead north of Destin contribute to the background c oncentration of 2.5 ng/M3 but the background lead concentration for all stations at night with a wind from the south is 1.5 ng/M3, which indicates that there may be more contribution to th e Destin background from winds from the
North.

FINAL REPORT- Destin Airport Page 13 of 39 6/19/2007 Total organics listed in the chart above include 5 of the 12 materials detected in the Summa ® canister air samples (analyzed by method TO-15). T he other seven chemicals or compounds were not considered because they were not present a t more than two locations or they could not (due to wind direction) have been contributed to th e air under study by the airport operations.

Organic concentrations around the airport (IMPACT) are statistically similar to the background concentration. Further study is needed to obtain m ore data points at these locations to definitively conclude that airport operations contr ibute more organics than observed just from the background.

Lead particulate was higher than background in samp les around the airport based on the variable IMPACT by AIRPORT operations. Since the only sampl e station with night AIRPORT IMPACT was Misty Way, the observation of higher day versus night lead levels is consistent with higher daytime airport flight operations versu s night.

What is interesting about this data set is the nigh t airport impact values are lower than the night background at stations 4 and 5.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

As observed in the body of this report, the only tw o organics that were predictors of airport operations were tetra ethyl lead and ethylene Dibro mide. Neither one were found in the study samples. Consequently, organics data is useful but not an absolute predictor of impact by airport operations.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

June 19, 2007

FINAL REPORT- Destin Airport Page 17 of 39 6/19/2007 Chart 6 shows a marked difference in lead observed at the EMS station with wind from the north
versus wind from the south. This can be attributed to the potential of lead particulate from airport operations impacting the station because it is immediately downwind from the airport and most of the wind direction during the study was fro m the north.

Night wind from the south is almost half the wind f rom the north at the urban background station 4 and 5. This may be the result of cleaner air fro m the Gulf (winds from south) versus other sources north of Destin that may contribute to the Destin air quality when the wind is from the
north.

Chart 9 shows that the organics measured in the air samples vary by location. Since Buck Destin Park and the Harbor are not impacted by the airport , the data shown above indicates that there are sources of organics in Destin that generally co ntribute to the ambient background and that they vary at the stations 4 and 5 as much as they v ary at the three sites adjacent to the airport.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 18 of 39 6/19/2007 STATISTICAL DISCUSSION OF SAMPLING RESULTS This section of the executive summary describes the statistical approach and the evaluation of data obtained in this sampling project at the Desti n Airport.

SAMPLING PROJECT COMPARISON REFERENCE The air concentrations at each of the five sample s ites were summarized into one of the following fourteen data sets for purposes of comparing those fourteen combinations of variables to the urban background data from site 4 and 5. Note, sit e 4 (Buck Destin Park) and site 5 (Harbor Road) were identified as urban background for this study.

Project Data Set Number

In addition to comparing the fourteen data sets (li sted in the above chart) to the urban background air concentration, the sampling project data was also used to compare each pair of
data sets to each other to see if there was a stati stical difference between the variables under review. Differences can then be used to identify w hether specific variables indicate airport air impact. The following seven data pairs were statist ically compared as part of this project sampling analysis.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

June 19, 2007

FINAL REPORT- Destin Airport Page 19 of 39 6/19/2007 STATISTICAL SAMPLING PROJECT RESULTS
The following chart (See Appendix 5) shows the t-Te st results for the comparison of the fourteen data sets to the urban background air concentration for each of the three air pollutant families reviewed (total suspended particulate [TSP], lead p articulate, and total organic compounds):

The chart shows the probability that the air concen tration, for each data set 1 thru 14, is from the same air sample as the urban background air concent ration. For example there is a 1% chance
that “Lead Particulate” concentration measured in t he urban background sites (4 and 5) is fromDestin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 20 of 39 6/19/2007 the same air sample as the “Lead Particulate” conce ntrations measured in samples with the data set of variables “Night” and “Wind from the South”. Highlighted cells in the above chart show a less than 25% likelihood that the data set air samp le is the same as the urban background.

The following chart shows the t-Test results for th e comparison of the seven paired data sets. These results identify the probability that the eac h of the paired data sets are from the same air population. Lower probability (less than 25%) like lihood that the condition 1 and condition 2 data set are from the same air sample are highlight ed in the following chart.

In the above chart, a high probability indicates th at there is no statistical difference between the air concentration from the air sample in condition 1 versus the air sample in condition 2 (for each paired data set). It is interesting to note that t here is only a 2% probability that at NIGHT, lead concentrations from NORTH WIND air samples are the same as lead concentrations from air samples from the SOUTH WIND data set.

Data from this analysis indicates that lead particu late air concentrations (Appendix 5, Table 4) associated with the variables “Night and Wind from South” was 1.4 nanograms per cubic meter and the value for “Night and Wind from the North” w as 2.5 nanograms per cubic meter. The tTest indicates that there is a very low probability (2%) that these two air samples are the same.

The actual average air concentration in micrograms per cubic for each family of pollutant (TSP, lead, organics) and each data set of variables is i ncluded in the following three charts labeled TSP Statistical Analysis, Lead Statistical Analysis , and Total Organics Statistical Analysis. The average air concentration of the condition 1 variab le is included in column 2 and the average air
concentration of condition 2 is included in column 4, for each chart. The t-Test comparedDestin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 22 of 39 6/19/2007 The TSP (particulate) STATISTICAL ANALYSIS data in the chart above indicates that only the first two rows (of a total of 21 data sets evaluate d) of data sets have less than 25% chance that the particulate measured in the air sample for cond ition 1 is from the same air as the air sample
in condition 2.

The conclusion that can be drawn from this chart is that 19 of the 21 data sets evaluated statistically indicate a high likelihood that the a ir sample in condition 1 is the same as condition 2 with respect to particulate concentration.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

With respect to airport operations, the data indica tes that there is only a 12% chance that the daytime lead particulate in the air sample related to the variable “AM IMPACT from airport” [value 0.0038 micrograms per cubic meter] is from the same air population as the urban background. This means that there is a 7 in 8 chan ce that the airport is having an impact on the locations adjacent to the airport during daytime fl ight operations for lead particulate.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 25 of 39 6/19/2007 AIR IMPACT CRITERIA DISCUSSION Due to the limited number of air samples taken and the short duration of the air sampling program, the data is not reliable to predict or cha racterize long term ambient air quality in and around Destin. In order to put the data in perspec tive with regard to regulatory standards for risk exposure, Tetra Tech has prepared the following tab les to show the highest air concentration observed during the sampling versus national and re gulatory standards and ODOR STANDARDS. There two sets of charts; one for ODOR using concentration units of parts per million (PPM) and micrograms per cubic meter (ug/M3 ) and one for regulatory standards again in units of PPM and ug/M3. Details are presented i n Appendix 14.

The only compound that was above a regulatory or he alth standard was the methylene chloride (highlighted Appendix 14 Table 2) observed only in one sample on only one day at the station 4 (Indigo) location. Previous discussion indicated t hat hexane was also observed at the same station and same sample time as the methylene chlor ide. Since the wind was from the north that day and at that station, the assumption is that sol vent or painting operations were occurring north of the Indigo station and the chemicals were carrie d by the wind toward the station.

Tables 2 and 3 show the maximum detectable concentr ations in the air sampling project compared to the following agency standards: EPA Re gion 9 PRGs, the ASTDR MRLs, and the National Ambient Air Quality Standards. The maximu m Methylene Chloride concentration exceeded the EPA Region 9 PRG by nearly a factor of four, but it was below the ASTDR MRLs by a factor of approximately 150. The other standa rds were not exceeded by any of the
maximum detectable concentrations.

Tables 4 and 4 show the odor thresholds obtained fr om several sources compared to the maximum detectable concentrations in the air sampli ng project. The sources and the odor
thresholds are shown in Table 4 and Table 5. The m aximum acetone concentration exceeded the lowest number in the range that AIHA reported by 15 %, however, the maximum acetone concentration did not exceed the highest number in the AIHA range. None of the other
maximum concentrations exceeded the odor thresholds shown in Tables 4 and 5.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 27 of 39 6/19/2007 Acetone was observed to be above the odor threshold listed by AIHA and listed in the following chart. Acetone was the only organic found in the T O-15 sampling of detected chemicals that was observed to be above any odor threshold.

No odor study was conducted to determine if petrole um odors from fuel use and dispensing at the airport migrate beyond the airport boundary dur ing wind conditions that would have carried them to one of the sample stations.

Review of the data from the US EPA EPCRA list of so urces that emitted acetone indicate that
there are facilities in the area that have acetone emissions. This data is included in Appendix 13 for reference. No conclusion has been drawn regard ing whether the industrial sources of acetone versus the airport were the major contributor of ac etone in the Destin background air samples.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 29 of 39 6/19/2007 SAMPLING PROJECT METHODOLOGY DISCUSSION Tetra Tech reviewed several airport air studies and determined that the following list of target substances would provide data to characterize the p resence or absence of chemicals typically associated with plane side or ground side airport o perations. The initial sampling project review included a detailed analysis of valid methods to ob tain data, confirmation of appropriate and approved sampling methods, confirmation of laborato ry analytical methods and internal quality control reports from the laboratory to validate the chemicals observed from the sampling event, identification of calibrated sampling equipment, an d identification of competent technical support for conducting the operational sampling. T he following table summarizes that initial investigation and identifies accepted EPA methods f or analyzing the target substances.

considered air toxics and harmful to the health of exposed populations and the
environment. *2 - PAH (Polnuclear Aromatic Hydrocarbon)

Tetra Tech determined that the expected concentrati on of PAHs in the ambient air as a result of airplane operations at the Destin Airport was not c ost effective within the fee structure of the sampling project. Tetra Tech’s review of airport data, fuel data, and discussions with Dr. Sucha Parmer (Atmospheric Analysis and Testing Inc.) resu lted in dropping PAHs and acrolein from the initial sampling project. Initially these two substances were considered probable target substances that may be expected to be present in av iation fuel combustion versus the result of gasoline, diesel, or urban activities in and around Destin that may release these compounds.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 30 of 39 6/19/2007 Lead particulate was chosen as the likely indicator of the use of AVGAS (or airplane fuel specifically formulated for internal combustion pro peller driven planes). See the discussion and details of AVGAS and JETA in Appendix 13 for refere nce. In addition to sampling for lead compounds as particulate, the sampling project also collected air samples of particulate to determine if airport operations were impacting site s differently.

For purposes of this analysis, the Destin urban amb ient air concentration or background was identified as the total day and night air concentra tions for each material (TSP, lead, and total organics) at sample station 4 (Buck Destin Park) an d station 5 (Harbor Road).

The final sampling project implementation test plan was developed along with a testing program to obtain multiple day samples (where airport impac t was expected to be higher than night time sample periods). The detailed sampling plan is pre sented in Appendix 1 along with figures showing sample locations and impact areas.

FINAL REPORT- Destin Airport Page 31 of 39 6/19/2007 SAMPLING PROJECT ASSUMPTIONS
The sampling project assumptions were used to devel op, implement, and analyze the data from the Destin Airport sampling project:

• Airport operations result in the release of air con taminants into the atmosphere including organics and particulates.

• Activity in and around Destin also result in the re lease of air contaminants into the atmosphere again including organics and particulate s.

• Specific chemical markers related to airplane inter nal combustion engine operation are know to be different than chemicals p resent in the community resulting from combustion operations by automobiles , trucks, and other fixed and mobile sources of pollutants.

• AVGAS used only in internal combustion propeller dr iven airplanes (not jets) contains the chemical additives tetra ethyl lead an d ethylene Dibromide and when combusted will potentially result in lead compounds as part of the airplanes exhaust gas. These lead compounds can be used as c hemical markers of airport operations since lead is not expected car and truck exhausts (gasoline does not contain lead).

• Air concentrations of airport operation “Chemical M arkers” will be higher at the sites adjacent to the airport versus the presence o f these chemical markers at city background sites.

• Sample sites located downwind from airport operatio ns are classified as “Impacted” by airport operations.

• Sample sites located upwind from airport operations are classified as “Not Impacted” by airport operations.

• Sample sites located adjacent to the airport during variable wind direction are considered to be “Impacted” by the airport for purp oses of this sampling project.

• The sampling project hypothesis was evaluated using the “t distribution” or t-test statistic for sample site data averages (means). T he test was used to determine the probability that the sample results for a specific site are from the same “sample population” as the Destin City Background sample si tes of the Harbor and Buck
Park. The “t distribution” statistical method was used because the number of samples was less than 30 in each case and the popul ation standard deviation was
not known.

• Sample sites 1, 2, and 3 were located adjacent to t he airport and included a residence at Misty Way, Buck Park, and a residence at Indigo Court.

• Sample sites 4 and 5 were located at a distance fro m the airport and were chosen to be the non-impact urban background and ambient c onditions.

• Sample collection methods followed US EPA methods f or particulate and organics.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 32 of 39 6/19/2007

• Sample materials and filters validated by either du plicate summa® samples or filter field blank analysis.

• Sample control and integrity was confirmed by use o f chain of custody.

• Sampling operations were conducted by qualified per sonnel and no deviations
from method were observed.

• Meteorological data for wind direction was obtained from the National Oceanic and Atmospheric Administration data base for Destin Beach Airport (station No. 53853).

• Over 150 internal combustion propeller planes and j et engine driven planes landed and took off during each of the daytime samp ling project sample periods as confirmed by the Destin airport flight log.

SAMPLE COLLECTION Air samples were collected in one high-volume air s ampler (General Metal Works Model GL1000/H TSP) and one Summa ® canister with a 12-ho ur limiting orifice at each of the five sample locations. These locations are discussed in detail in the body of this report and can be seen in Figure 1 – Destin Airport sampling project Sample Site Locations. The sampling project collected six 12-hour particulate samples and seven 10-hour organic compound samples from each of five sites in and around the Destin airport . The testing period started Tuesday at 7:00 am on April 3, 2007 and concluded on Saturday April 7, 2007 at approximately 7:00 pm. The sampling project plan included taking concurrent pa rticulate and organic samples at each site but due to test equipment configuration, the organics s ample period was only 10 hours versus the particulate (total suspended particulate and lead p articulate).

AIRPORT CHEMICAL MARKERS The airport fueling operation provides ExxonMobil J etA fuel for jets and AVGAS (ExxonMobil 100LL) for internal combustion propeller driven air craft. This data was confirmed by both information from the Destin Airport website and sta ff at the airport. The AVGAS 100LL has two additives to prevent cylinder fouling in intern al combustion engines used on propeller driven airplanes. AVGAS is used only in internal combusti on propeller-driven aircraft and its
combustion air emissions and release into the envir onment are different than the emissions of jet fuel, gasoline, or diesel fuel.

Therefore, the two additives, tetra ethyl lead, and ethylene dibromide were considered "chemical markers" for purposes of this sampling project to differentiate air concentrations (based on fuel use and combustion emissions) between planes and ge neral ground based vehicles (cars, trucks, lawnmowers, etc.) or urban background.

In addition to these two chemical markers, there wa s an expectation that lead particulate could be present as a result of use of AVGAS. Lead is not a n additive to gasoline, JetA (kerosene), or diesel fuel; therefore, lead compounds found in air samples would distinguish airport operationsDestin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 33 of 39 6/19/2007 from general Destin city activity. All samples wer e analyzed for these chemical markers to
determine whether or not the chemical markers were present.

Thirty-five six-liter Summa canister samples were c ollected and analyzed for volatile organic compounds (VOCs), including ethylene dibromide, and tetra ethyl lead (EPA T0-15 method). Thirty samples were collected on quartz filters usi ng high-volume pumps. Thirty samples plus one blank were analyzed for lead using EPA Method I O-3.5 Metals in Ambient Particulate Matter by ICP/MS and total suspended particulate by PM-10 (Gravimetric).

DESTIN AIRPORT DATA The Airport is owned by Okaloosa County and has one 5,000 foot runway with a 142 degree or 322 degree heading. This small publicly owned airp ort is not certified for air operations under FAR Part 139, nor is it permitted to conduct intern ational operations. According to recent airport operational statistics, the airport serves 61 aircr aft based at the field (37 single engine, 22 multi engine, and 2 jet aircraft). There were a reported 63,000 total operations at the field per year consisting of 600 air taxi operations, 15,400 local general aviation, 46,700 transient general aviation, and 300 military operations. This is an average of 172 flight operations per day. Airport operations include landings, takeoffs, taxi ng, and ground operations that include fueling
the aircraft.

SAMPLING FIELD OPERATIONS DISCUSSION TRC Environmental Corporation was contracted by Tet ra Tech, Inc., to ensure that the air sampling equipment and the samples were handled acc ording to EPA protocols. TRC was responsible for the setup, calibration, operation, and management of the sampling equipment, as well as the filter media exchanges. Tetra Tech, In c. personnel provided support to TRC in these efforts. TRC prepared a report discussing the samp ling event and it is included in Appendix 2. The report also includes data sheets and the calibr ation information.

The Chain of Custody records (COCs) located at the beginning of Appendix 7 are correct. Some of the COCs located in the detailed pages of Append ix 7 were modified subsequent to the submittal of samples to the lab. The lab’s COC cha nges were in response to a few filter labels inadvertently being given incorrect sample identifi cation prefixes after a change in the sampling
schedule.Destin Airport – Final Air Sampling Report Prepared for the City of Destin, Florida

FINAL REPORT- Destin Airport Page 34 of 39 6/19/2007 WIND DIRECTION DISCUSSION When determining the wind direction for each sampli ng period (10 or 12-hour periods), the predominant wind direction was chosen. In two of t he twelve-hour periods, the wind direction varied so much that there was no predominant wind d irection. In those situations, the wind
direction was identified in the data worksheets as “VARIABLE.”

If the analysis data set included wind direction as a parameter under consideration, the air sample average and statistical analysis included the varia ble data set in each column. For example, if the column heading was AM WIND FROM NORTH versus AM WIN D FROM SOUTH, the days and samples that had variable wind direction would have a value entered into both columns to account for the possible condition that the data sh ould be represented by each wind direction.
