Boyle, Ph.D., to conduct air quality testing relating to John Wayne Airport (JWA) jet aircraft emissions and authorize the City Manager to enter into a standard professional contract, which will have been approved by the City Attorney with Dr. Boyle? RECOMMENDATION: Approve the scope of work for the air quality study. 2. Authorize the City Manager to enter into a contract with Dr. Boyle for the Option Two study proposal (most rigorous option) at a not -to- exceed amount of $62,000; and approve a budget amendment (09BA -056) in the amount of $62,000 from unallocated General Fund reserves to account #0123 -8080. DISCUSSION: Background: At its February 10, 2009 meeting, the City Council adopted its priorities and action steps for 2009, including the following priority: "Continue to seek and implement measures to minimize the adverse impacts of John Wayne Airport through the implementation of the City Council's Airport Policy." One of the action steps identified to implement this priority was to "Conduct an air quality study seeking to determine effects of JWA jet aircraft on Newport Beach's air quality." Air Quality Testing Study Relating to John Wayne Airport Jet Aircraft Emissions May 12, 2009 Page 2 For many years, Newport Beach residents have expressed concerns to City officials about the fine black grit particulates that appears to be emitted from jet aircraft flying overhead. The concern has not been limited to the residue that seems to result, but also includes the potential health impacts to humans from ingesting these" jet engine fine particulate emissions. Until now, there has not been the sophistication of testing equipment nor the methodology to differentiate between diesel and jet engine fine particulate emissions; however, we have good reason to believe the science does now exist to identify the quantity of jet fuel emissions being emitted by jet aircraft from JWA and from any other airport. STUDY PROPOSAL: The air quality proposal on your agenda is from Karleen A. Boyle, Ph.D. I have previously engaged her to conduct a literature review of testing methodologies relating to aircraft emissions in order to familiarize herself with recent papers and testing procedures performed on aircraft emissions to determine if the science does exist; it is her opinion that it does. Her literature study is included as a staff report attachment. Her background references are excellent. Dr. Boyle's proposal outlines three alternative testing methodologies for JWA aircraft emissions. Option One is what she calls "basic air sampling." This sampling would be limited to testing for the chemical fingerprint associated with airport jet engine emissions. The estimated cost is $31,500. Option Two would provide "detailed air sampling" data to determine whether health issues exist. The air samples would test for airport- associated polycyclic aromatic hydrocarbons (PAH's) and metals and would predict the impact on human exposure. Six sampling stations are being proposed with lab tests. This study would cost an estimated $58,900. Option Three could be added to option two and would involve laboratory testing to determine jet aircraft emission accumulations in sediment in the Upper Newport Bay, the "impacts to Upper Newport Bay" option. The additional cost of this option is estimated at $40,000. The City Manager believes there are two good reasons to proceed with the Option Two air quality study. First, our residents have long been concerned whether health impacts exist from their being exposed to jet aircraft emissions. Second, the science appears to now exist to test for quantities of jet aircraft emissions, and that information could prove valuable in future EIR's required of the airport. Of course, the study could come to the conclusion that jet aircraft emissions are not cause for health concerns, but that information would be good to know and share with our residents. It is the City Manager's recommendation that the City engage Dr. Boyle to conduct the "detailed air sampling testing" (Option Two, the most rigorous) at a cost of approximately $58,900; however, he is asking for not -to- exceed authority for $62,000, as the testing costs will not be completely known until the air samples have been collected and he believes there should be some flexibility to react to the unknown as the study is being conducted. The study results should be available in early 2010. The proposal included in this staff report was received in February and our current price has been updated and refined, so it does not match the initial proposal figures. A professional peer review was conducted to Air Quality Testing Study Relating to John Wayne Airport Jet Aircraft Emissions May 12, 2009 Page 3 ensure the proposed methodology was appropriate, and the City Manager is satisfied with the changes made in the proposal by Dr. Boyle based on the peer review feedback. The City Manager proposes the City and Dr. Boyle enter into a standard professional services agreement, to be approved by the City Attorney, with the City Manager being authorized to sign. FUNDING: The City Manager is asking for a budget appropriation amendment of $62,000 from unallocated General Fund reserves to fund this study. Environmental Review: The City Council's approval of this Agenda Item does not require environmental review. Public Notice: This agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the Council considers the item).

Edwards Re: Dr. Boyle's Proposal Date: 4/27/09 The following is an updated outline regarding the current proposal by Dr. Karleen Boyle - Sudol and the City's monitor of the potential environmental impacts of aircraft emissions at John Wayne Airport, Orange County, California. Hopefully it will serve as a basis to respond to continuing questions and concerns that the City may face as regards the study. History Initially, various components of the City have continually raised the question of what and if any emissions are generated by aircraft that pass overhead at the rate of approximately 150 per day. Numerous comments through out the City confirmed that people felt they were being inundated with black soot that collected on patio furniture, pool covers, air filters and the like. It was with that in mind that the City began to investigate the possibility of conducting its own study to monitor the potential impacts of aircraft emissions. Independently through one source at the City and through my own investigation the person most likely to conduct such a study was determined to be Dr. Karleen Boyle- Sudol, t Rather than accept anything at face value the City asked Dr. Boyle to make a proposal but unlike most proposals it was to include and did include a complete survey of literature to support the type of project that Dr. Boyle was proposing. The proposal substantiated that the scientific community was able to demonstrate that "fingerprinting" of ambient emissions to demonstrate their source was possible. Proposal With the foregoing in mind Dr. Boyle proposed a variety of research approaches for evaluating the potential impacts of aircraft emissions. Included in the proposal and the one that the City decided to pursue was a Detailed Air Sampling, which included the measure of ambient particulate air pollution and associated polycyclic aromatic hydrocarbons ( "PAHs ") and heavy metals near the airport, including areas used for residential and recreational purposes. The current proposal's approximate cost is $52,000. The staff person at the City located and passed on almost simultaneously the study conducted by Dr. Boyle: "Evaluating Particulate Emissions From Jet Engines: Analysis of Chemical and Physical Characteristics and Potential Impacts on Coastal Environments and Human Health" which appeared in Transportation Research Record. The proposal includes the use of Minivols, which are air samplers placed in certain locations around the airport and therefore utilizing the field methodology and sample design would be able to compare or create a signature of airport vs. urban background; in light of outstanding studies such as the one conducted at LAX which demonstrated that particle associated concentrations of Copper and Vanadium were statistically significantly elevated in air samples. Essentially what testing determined was that in terms of associating the elevated Copper and Vanadium levels with aircraft, the best hypotheses is that the copper particles are due to brake wear as the planes land. Also, vanadium is used as an additive in jet fuel. These facts coupled with the lack of elevations in these metals in freeway sampling sites have led so far to the conclusion that they are aircraft - associated. The City's proposed testing would compare therefore the amount and type of particulate emissions associated with the airport and testing and whether they are distinguishable from urban background and freeway emissions. Assuming that the tests move forward it appears that the science supports the ability to distinguish between the two, because of the heavy metal and PAH fingerprinting of airport associated impacts versus other normal urban background. Questions Q: Is there science to support distinguishing airport versus urban background? A: Yes. Numerous Studies, including the supporting literature and studies, numbering 56 as cited in the City's proposal. Q: What about the question of diesel fuel versus jet fuel? A: Because of the testing which has demonstrated the ability to distinguish heavy metals and PAH fingerprints from sampling, while difficult it is obtainable. Moreover, the sample design and field methodology were designed with the objective of distinguishing airport- associated emissions from other urban background sources. Since substantial diesel emissions are associated with airport activities, including baggage transport vehicles, aircraft support vehicles, public transit vehicles, etc.; these emissions should be included in assessing overall airport impacts to air quality. That is the purpose of having multiple field sampling stations, to allow us to measure airborne particulates (and associated PAHs and heavy metals) in proximity to the airport in comparison to "clean" coastal control sites, airport- adjacent residential areas, and non - airport adjacent urban sampling stations. Dr. Boyle's study at LAX used a similar design and did find statistically significant differences between the amount of particle -bound heavy metals in air samples near the airport vs. samples adjacent to a freeway with a high volume of diesel truck traffic. Airport air samples had significantly higher levels of particulate copper (possibly from brake wear on landings) and vanadium than control and freeway stations, while freeway stations had significantly higher levels of particulate lead than airport or control stations. Simply put testing has demonstrated elevated levels of lead at freeway sites which is associated with diesel whereas airport samples show elevated levels of copper and vanadium which are associated with jet fuel - not diesel in any significant respect. 2 In addition one of the peer - reviewers specifically addressed this question and concluded that that there is sufficient data available that supports that there are differences between emission profiles of diesel and jet engines. In particular, a clear difference exists between the ratio of organic carbon to elemental carbon (OC/EC) found in the two emission types. Q: What is a MiniVol? A: It is the type of air sampler Dr. Boyle is proposing for use. It is an integrated sample over time. Dr. Boyle selected a standard EPA - approved air sampler (MiniVol) which means that both the sampling machine and sampling protocols have been extensively and scientifically reviewed before being approved by the EPA. The other benefit to using an EPA - approved methodology is that it allows her to make meaningful comparison of the City's data set with other data sets collected using these same methods. This makes the data scientifically defensible and provides a broader context for use when interpreting the results. Q: What about the costs? A: The costs quoted, which appear as an exhibit on her proposal were merely duplicated verbatim from the testing lab DRI. While it has been approximately six (6) months from the date of the proposal and the longer the time before actual testing begins as best as can be determined the quotes remain accurate. Also because Newport Beach is a public agency, they obtain a break on costs and expenses from the Lab. Q: What about review of the proposal by stakeholders? A: From a scientific standpoint it is not normal for stakeholders to be involved in a scientific proposal at this stage. What is standard from a scientific standpoint is for peer - review by peers in the field for evaluation of sample design and field methodology. From the beginning Dr. Boyle has never opposed this and in fact had suggested a number of possibilities. Q: Will the proposal receive peer- review? A: Yes. Currently Dr. Boyle has oral commitments and has exchanged information with Dr. Gertler at DRI; Dr. Fine at AQMD and Dr. Weiner at UCLA. She is waiting for all of the comments back and then if necessary will refine the proposal to incorporate their suggestions. If there are additional costs or expenses associated with the proposal she will make the City aware of those as soon as possible. As an example Dr. Gertler made certain suggested changes and comments including but not limited to his recommendation to change the proposed 24 hour MiniVol sampling period to a shorter sampling interval. He pointed out that airflow in the study area is typically onshore during daylight hours, switching to offshore flow in the evenings as temperatures drop. Sampling during both periods would include emissions from both upwind and downwind of our sampling locations, making our source profiles less concentrated and specific. The recommendation was incorporated. Q: Why do the testing? A: There are a variety of reasons. However the City obviously must decide what they determine to be in their best interests. Initially the citizens in the city have repeatedly raised the issue. Irrespective of the results the testing would establish some type of base line for measuring the future, including but not limited potential increases in the future. In addition it may prove to be a negotiating tool for the future. Also, contrary to what other may say, what the data will provide is a measurement of the amounts of heavy metals and PAHs at sampling stations in varying proximity to potential urban emission sources, including heavy auto traffic (freeway) and the airport. That information can be used by planners to determine whether airport- associated emissions make up a significant portion of the overall air pollution load of the region. Or if automotive sources are so substantial that any airport effect is undetectable. Air quality data collected at the sites of concern allows city officials and regulators to use their limited resources to address real, rather than imagined environmental impacts. The data set can indicate whether mitigation measures should be explored, and if needed, how they can be most effectively focused. A frequently suggested strategy for mitigating airport air quality impacts is to switch from diesel - fueled support vehicles to less - polluting options such as electric or hybrid vehicles. This approach is usually more cost - effective and feasible than reducing emissions from jet engines themselves. Q: What type of questions will be addressed in the study? A: How many fine airborne particles are present in the ambient air? What concentrates of PAHs, trace metals and nitrogen species are associated with these particles? Does the particle load and/or chemical signature vary between sampling locations? How do the levels of fine particles and/or PAHs and heavy metals measured near John Wayne Airport compare to field measurements of other sites from the scientific literature? How do these levels compare to standards set by air quality regulations? Q: But isn't LA doing a study? A: They are doing a variety of studies, all of which are related to environmental impacts 45 miles away. Moreover Dr. Boyle's report will compliment the LAX report, however it is much more chemically detailed as it will be able to distinguish in particular, between the ratios of organic carbon to elemental carbon (OC/EC) found in the different emission types. Q: Is there a guarantee that the results will support people's beliefs regarding the effects of the airport on air quality? A: No. We are talking a scientific study; the science is what it is. Q: Is there a risk of doing the study? A: Yes, if people have a preconceived notion of the outcome. The results could be Inconclusive; conclusive but show no negative effects from the airport; or rd Conclusive and show negative effects of the airport. In all cases a baseline of information will be established. Q: If the study demonstrates that there are significant environmental impacts as a result of Jet Fuel Emissions will it shut down the airport? A: No. However the County will have to deal with the issue of future expansion and its impacts as well as incorporating certain mitigating measures to deal with the impacts. LITERATURE REVIEW AND MONITORING PROPOSALS TO ASSESS POTENTIAL ENVIRONMENTAL IMPACTS OF AIRCRAFT EMISSIONS AT JOHN WAYNE AIRPORT ORANGE COUNTY, CALIFORNIA Karleen A. Boyle, Ph.D. February 2009 TABLE OF CONTENTS Section Panes 1 Executive Summary 2-4 2 Review of Scientific Literature and Relevance 4-6 to Proposed Project 3 Summary of Proposed Sampling Options 6-10 4 References 11 -15 Table 1 Estimated costs of research protocols 16 Appendices 1 Annotated bibliography CD 2 Budget worksheets CD I Section 1. EXECUTIVE SUMMARY Background The purpose of this report is to provide a review of the scientific literature as well as a series of proposals to monitor the potential environmental impacts of aircraft emissions at John Wayne Airport, Orange County, California. Residents near airports frequently complain about "soot" depositing on their property, and sampling near runways confirms the presence of high concentrations of fine particles in the air and in dry deposition on land and water in the vicinity of airports. Moreover, a survey of recent scientific publications demonstrates that field sampling at airports worldwide has in fact detected elevated levels of fine particulates (defined as 10 microns or less, i.e., PM10 and below), heavy metals and polycyclic aromatic hydrocarbons ( "PAHs') in air, soil and water near airports. These three components of aircraft emissions have the potential to adversely impact both human and environmental health. t Scientific Support to Justify Field Data Collection at JIMA The scientific community has demonstrated that "fingerprinting" of ambient emissions to identify their source is possible and has been done in other systems using both heavy metals and polycyctic aromatic hydrocarbons (PAHs) to distinguish between various anthropogenic emissions, including automobile traffic, aircraft emissions, and urban background air pollution. Accordingly, it is in fact possible to test for and distinguish between the various type of emissions. Therefore there is substantial support in the scientific literature to justify field data collection to measure current levels of particulates, heavy metals and PAHs in the vicinity of John Wayne Airport, and to evaluate the potential of environmental impacts associated with increasing levels of air traffic. Research approaches for evaluating potential impacts: • Measure ambient particulate air pollution and associated PAHs and heavy metals near the airport, including areas used for residential and recreational purposes. • Measure heavy metals, PAHs and particle- associated nitrogen in dry atmospheric deposition or runoff water in vicinity of runways. Nitrogen is of particular concern because Upper Newport Bay is already eutrophic and subject to nuisance blooms of macroalgae. • Measure the effects of these airport associated pollutants on estuarine habitats and organisms using laboratory microcosm experiments. ' The scientific literature supporting the foregoing is set forth in Section 2 of this Repork Research Options Options for field air sampling are presented in detail in Section 3 (pp. 6-10). Laboratory microcosm experiments designed to measure airport- associated impacts to estuarine habitats are also discussed. The proposed approaches can be matched to research priorities: Research priority Recommended protocol Estimated Cost Basic air sampling Air 1 $27,5222 Detailed air sampling Air 2 $45,900 Impacts to Upper Newport Bay Lab microcosms Range:$930- $38,0703 Summary of Research Options Several options are presented for measuring levels of chemicals of concern near the airport and testing whether airport- associated impacts can be distinguished from urban background pollutants (fingerprinting). Selecting the best protocol to meet your research needs and budget constraints depends on which potential impacts are of highest priority to identify. Protocol t - Basic Air Sampling Basic air sampling will yield measurements of PAHs and metals in air samples taken near the airport. These will be compared to air samples from a clean coastal control site and a site subject to high automobile emissions to attempt to identify a chemical fingerprint associated with airport emissions. Protocol 2 - Detailed Air Sampling; Assessing Residential Exposure If human health impacts are of primary concern, air sampling protocol 2 will give the most robust data set for that assessment by including additional sampling stations at residential and recreational areas near the airport. These data will allow us to test whether airport- associated PAHs and metals are detected in these areas and will allow estimates of human exposure to be made. This protocol will also improve our ability to fingerprint airport emissions by adding data from additional sampling sites. z Cost estimates for all of the research options are broken down and explained in detail in the budget worksheets on the accompanying CD. ' Cost estimates for the microcosm experiments are presented in more detail in Table I (p.16)of this report. Detailed Chemical Fingerprinting If establishing a detailed chemical fingerprint is a high priority, air sampling protocol 2 can be combined with laboratory experiments that expose microcosms to doses of aircraft or automobile emissions collected at air sampling sites and measure the resulting PAH and metal concentrations in microcosm sediments, water, animal and plant tissue. Comparing chemical signatures from air traffic and automotive traffic in the largest variety of media maximizes the chances of isolating an airport- associated chemical fingerprint and evaluating potential habitat impacts. Lab Microcosms- Human Health Impacts and Impacts to the Estuary If both human health impacts and impacts to the estuary at Upper Newport Bay are prioritized, a combination of air sampling and laboratory microcosm experiments is the best choice. This approach allows the fate and effects of the air contaminants measured in the field to be tracked in an estuarine environment. My recommendation for a baseline data set would be to combine basic air sampling with experimental microcosms testing: toxicity, invertebrate bioaccumulation and environmental fate. Additional testing could be added as funding allows, or to pursue findings of interest in the baseline data set. The budget worksheet on the accompanying CD allows detailed cost comparisons of the various approaches. Section 2. REVIEW OF SCIENTIFIC LITERATURE AND RELEVANCE TO PROPOSED PROJECT Airport Associated Environmental Impacts A search of the recent scientific literature shows that field sampling at airports worldwide has detected elevated levels of fine particulates (particles 10pm and smaller), polycycic aromatic hydrocarbons (PAHs), heavy metals and particle- associated nitrogen in air (Westerdahl et al. 2008, Fang et al. 2007, Boyle 2001, Tsani- Bazaca et al. 1984)4, soil ( Romic and Romic 2003, Sharmila et al. 2008), and water (Golomb et al. 2001) near airports These airport- associated emissions have the potential to adversely impact both human health and habitat quality. Fine particulate air pollutants have been associated with increased risks of cell mutation (Hopke 2008, McCartney et al. 1986), asthma attacks (DeLeon et al_ 2004), and human mortality due to cardiovascular and repiratory causes ° These reference the science and literature cited in Section 4 and more particularly described in the Annotated Bibliography found on the CD accompanying this report. (Klemm et al. 2001, Kinney and Oezkaynak 1991, Schwartz 1991). In addition to their negative effects on human health, chemicals associated with these particles, especially heavy metals and polycyclic aromatic hydrocarbons, can adversely impact habitats subject to their deposition. Both heavy metals (Horai et al. 2007, Franca et al. 2005, Kut et al. 2000) and PAHs (Lee et al. 1999, Woodhead et al. 1999, Walker et al. 2004) have been shown to accumulate in sediments and organisms, where they can have toxic effects at various life stages (Greco at al_ 2001, Geffard et al. 2002). Because of their frequent proximity to human development, estuaries are often subject to such adverse environmental impacts. Particle- associated nitrogen species are another potential environmental impact. Atmospheric nitrogen deposition associated with air pollution has been documented worldwide (Liu et al. 2008, Ayars and Gaob 2007, Whitall et al. 2003) and has been shown to alter habitats by altering plant physiology (Skinner et al. 2006, Gidman et al. 2005) and changing vegetation communities (Solga et al. 2006). Many estuarine habitats worldwide are adversely impacted by excessive nutrient inputs (eutrophication) due to human activities (Kedong and Harrison 2008, Dolbeth et al. 2007, Ellegaard et al. 2006). Atmospheric nitrogen deposition represents another source of nutrient enrichment to these systems (Nakamura et al. 2005). This is of particular concern for Upper Newport Bay, since the estuary is already highly eutrophic and subject to nuisance blooms of macroalgae (Boyle at al. 2004, Kamer et al. 2001). Isolating the Source of Chemical Inputs A persistent challenge in environmental impact sampling is isolating and quantifying the various sources of chemical inputs against urban background contaminants. Sediment profiles of heavy metals and PAHs have been found to reflect adjacent land uses (Kimbrough and Dickhut 2006) and are frequently used to identify "fingerprints" of anthropogenic inputs to a watershed (Walker et al. 2005, Bixian et al. 2003, Cal- Prieto et al. 2001). Similarly, heavy metals and PAHs associated with particulate air pollutants can be used to "fingerprint° ambient emissions (Chuersawan 2008, Ninga et al. 2008, Mastral et al. 2000, Zheng and Fang 2000, Rasmussen 1998). Increasingly stringent air quality regulations have spurred the development of analytical techniques to identify sources and distinguish between various types of anthropogenic emissions including automobile vs. background urban vs. refinery (Ravindra at al. 2008, Walker et al. 2005). Scientific Support for This Study There is substantial support in the scientific literature to justify field data collection to evaluate potential environmental impacts associated with increasing air traffic at John Wayne Airport. Studies of airports worldwide have documented increased levels of fine particulates, heavy metals, PAHs and nitrogen species. All of these compounds have been documented to have the potential to adversely impact human and environmental health. The sampling technology and analytical techniques are well developed to measure these contaminants in the Field, near areas of concern (Cooney 2008, Yu et al. 2004). Areas at high risk for environmental impacts exist in proximity to John Wayne Airport, including residential and recreational land, as well as protected wetland habitat in Upper Newport Bay, which is already threatened by numerous anthropogenic impacts. In addition, chemical fingerprinting techniques are developed that give a good probability of isolating an airport- associated emission signature from general urban background pollution. The approach described in this report combines these research methods to obtain quantitative field data on which to base evaluations of potential air quality and habitat impacts associated with John Wayne Airport. Section 3. RESEARCH OPTIONS FOR ASSESSING POTENTIAL ENVIRONMENTAL IMPACTS OF AIR TRAFFIC AT JOHN WAYNE AIRPORT Two Air Sampling Options and/or Combination with Microcosm Experiments The following options are arranged from least to most complicated. As complexity and sampling increase, so does the cost of the project. The major expenses associated with these sampling options will be the rental of sampling equipment and the cost of chemical analyses of the samples. Two air sampling protocols are presented to measure air quality impacts near the airport and to attempt to differentiate airport emissions from urban background inputs. If desired, air sampling can be supplemented with laboratory microcosm experiments examining the fate and effects of particle doses and/or runoff collected at the airport on estuarine habitats. Ten experimental options are described. I recommend focusing on particle- associated PAHs and heavy metals as chemicals of interest because there is a well-developed scientific literature to support their use, they have been documented to have the potential to adversely impact environmental and human health, and levels of concern for most have been established by regulatory agencies_ If habitat impacts are a concern, analyses for nitrogen can be included. These analyses are substantially less expensive than PAH and metal analyses. Sampling in many systems worldwide has demonstrated that nitrogen species associated with atmospheric particulates can lead to increased nutrient loading at sites in proximity to, or downwind of, air pollution sources. In several cases, the effects of this increased nutrient loading are measurable in changes in vegetation patterns or species distributions in the impacted area. The issue of increased nutrient deposition associated with particulate air pollution near the airport is addressed through laboratory microcosms. This is of particular concern for Upper Newport Bay since previous research has demonstrated high anthropogenic nutrient loading to the Bay (Boyle et al., 2004), and documented its role in facilitating nuisance blooms of macroalgae in this estuary (Kamer et al., 2001). Acceptable levels of water column nitrogen are regulated under the Clean Water Act. For each protocol below, baseline sampling has been set at the minimum number of locations and replicates (samples per location) which will allow statistical analyses of the data set. If budget allows, increases in sampling location or replicates will increase the ability of the statistical tests to detect whether trends in the data are statistically significant. Sampling locations in urban, high traffic areas have been included to attempt to discriminate between airport- associated and other urban background emissions ( fingerprinting "). if fingerprinting air traffic associated emissions is not a high priority, these sampling locations can be omitted. All budget estimates are approximate. There is potential for reducing the cost of chemical analyses by partnering with other researchers in exchange for co-authorship of results, or by running large numbers of samples which will qualify for a reduced rate at most commercial labs. General Sampling Structure Field air monitoring would be conducted at the following general locations. Different protocols increase the number of sampling locations to obtain progressively more detailed data sets. Proposed sampling locations: 6 • 2 at airport, 1 upwind and 1 downwind of runway • 2 potential impact sites - airport- adjacent residential/recreational/ habitat areas to assess potential human health and environmental impacts. • 1 site with high automobile emissions and minimal air traffic exposure to obtain background urban emission values for fingerprinting purposes. • 1 clean control site sampling coastal air subject to minimal pollution. Recommended minimum replicates per location: 3 Measuring particulate emissions and quantifying associated PAHs and heavy metals Research questions addressed: How many fine (2.5 Nm and smaller) airborne particles are present in the ambient air? What concentrations of PAHs, trace metals and nitrogen species are associated with these particles? Doewthe particle load and/or chemical signature vary between sampling locations? How do the levels of fine particles and /or PAHs and heavy metals measured near John Wayne Airport compare to field measurements of other sites from the scientific literature? How do these levels compare to standards set by air quality regulations? Both air sampling protocols are designed to provide quantitative data on levels of particle- associated PAHs and trace metals at sampling sites. These values can then be compared to values associated with human health impacts in the scientific literature and to acceptable levels stated in air quality regulations. Statistical analyses will be conducted to test whether a significant difference in PAH and metal concentrations is detected between locations in varying proximity to the airport. Data will also be analyzed to attempt to differentiate between airport- associated emissions and urban background emissions. Both protocols employ air sampling machines to actively sample ambient particles in a known volume of air. The Air 1 protocol samples three locations: downwind of the runway, the high -auto emission control, and the clean coastal control. The Air 2 protocol increases the spatial resolution of the data collected in Air 1 by adding three more sampling sites: upwind of the runway, airport adjacent residential and airport adjacent habitat. Saw Testing the fate and effects of PAHs, heavy metals and nitrogen in estuarine habitats exposed to airport derived particles. Research questions addressed and methods: See Table 1 (p.16) for summary. Are jet exhaust particles (JEPs) toxic? 96 -hour dose- response toxicity tests will be conducted. Larval fish will be exposed to increasing doses of JEPs collected at the runway sampling station and impairment or mortality will be measured. Do JEP- associated chemicals bioaccumulate in estuarine habitats? Bioaccumulation potential will be assessed through laboratory microcosm exposure tests in which organisms from "clean° reference sites are exposed to JEP doses from the runway sampling station. After exposure, tissues are analyzed for PAHs and heavy metals. Algal tissue is also analyzed for nitrogen. Bioaccumulation can be tested for using: Macroalgae (Ulva sp.) Invertebrates (mollusk) Vertebrates (larval fish) Do JEP- associated nutrients increase macroalgal biomass (blooms)? Biomass of macroalgae in laboratory microcosm test is measured throughout exposure and compared to controls. Where are JEPs stored in the environment (fate)? Laboratory microcosms containing "clean" seawater, sediment, macroalgae and reference invertebrates and vertebrates are exposed to JEP doses from the runway sampling station. After exposure, all media are analyzed for PAHs and heavy metals. Do JEPs increase water column and sediment nutrient levels (eutrophication)? Laboratory microcosms containing `clean" seawater, sediment, macroalgae and reference invertebrates and vertebrates are exposed to JEP doses from the runway sampling station. After exposure, all media are analyzed for nitrogen species. Do automotive emissions demonstrate a different chemical signature in estuarine habitats? A third experimental treatment exposing microcosms to doses collected at the automotive emission sampling station is added to the Fate protocol. Conclusion As previously stated, there is substantial support in the scientific literature to justify field data collection to measure current levels of particulates, heavy metals and PAHs in the vicinity of John Wayne Airport, and thereby evaluate the potential of environmental impacts associated with increasing levels of air traffic. The determination that the City must make is what types of impacts it wishes to test for and which potential impacts are of the highest priority to identify. A combination of air sampling and laboratory experiments will allow potential impacts to both human health and habitat in Upper Newport Bay to be investigated. The minimum data set necessary to accomplish this is the combination of Air protocol 1 with select laboratory toxicity tests. My recommendation for a baseline data set would be to combine basic air sampling with experimental microcosms testing: toxicity, invertebrate bioaccumulation and environmental fate. Additional testing could be added as funding allows, or to pursue findings of interest in the baseline data set. If fingerprinting emissions is a priority, the Air 2 protocol would provide the most robust data set for those purposes. For detailed fingerprinting, laboratory microcosms could be exposed to doses from both the airport and freeway sampling sites. The chemical signatures of each in sediments and water could 0 be compared to controls to attempts to isolate an airport- specific pollutant signature. The budget worksheet accompanying the executive summary allows cost comparisons of various approaches. This is an interesting research question, and any data that is collected will be a useful addition to the body of scientific knowledge on these topics. It will also provide planners, the public and the regulatory community with relevant decision - making information. 10 Section 4: Literature Cited Ayars, Jennifer and Yuan Gaob. 2007_ Atmospheric nitrogen deposition to the Mullica River -Great Bay Estuary.

From: Karleen Sudol [ mailto:kboylesudol @verizon.net] Sent: Wednesday, May 06, 2009 10:16 AM To: Bludau, Homer; Thomas Edwards Subject: Revised timeline and budget options for JWA sampling Hello Homer and Tom, I've attached a revised timeline and budget for the proposed sampling at John Wayne Airport. I spoke with the DRI lab today to confirm their sample turn - around time in August and their 6 week estimate is factored into the new timeline. As Homer requested, I kept the timeline conservative, but if we need to make the deadline before January 2010 let me know and I can revise our estimates. In terms of the budget, Homer asked me to prioritize scientific rigor of the study, so I've re- worked the numbers accordingly. The limiting factor changing our costs is the number of samplers we deploy. Our costs for time and analysis will remain constant with either approach, but adding samplers to the budget would improve the scientific rigor of our data. This is because we will be sampling at 6 different locations (control, upwind of airport, downwind of airport, 2 sites of interest adjacent to the airport (to be determined in consultation with you both), and a site removed from the airport but adjacent to a freeway (as our automotive emission sample). In any sampling design involving different locations, the "normal /background" variability between locations and over time must be considered. If we are able to have a sampler running simultaneously at all 6 locations, that allows us to get a statistical estimate of normal spatial variability between these sites (we are getting a snapshot of how different they are from each other during the same 12 hour period). This makes it easier to determine whether any differences in emissions detected between sites are "real" or a function of variability over space and time. So, the bottom line is - the more samples we have, the better our statistics work and the more likely any differences we detect are "real ". This is always the case in science and there is always a trade -off between statistical rigor and the realities of budgets. After consulting with several colleagues at DRI and UCLA, the consensus is that a scientifically rigorous approach would be to run 6 Minivol samplers simultaneously (1 at each sampling location during the same 12 hour period). This basic sampling method would be repeated on 3 different days to give us a sample size of 3 (the minimum number needed to run statistics) for each location. Our minivols give us data on particle concentrations and the heavy metals associated with those samples. To get our PAH data we need to run the XAD filter samplers alongside the minivols so that we can measure the types and concentrations of polycyclic aromatic hydrocarbons (PAHs, the agents of most concern when evaluating toxic /carcinogenic effects). The XAD samplers are the most expensive piece of the sampler budget. Ideally we would run 6 XADs alongside our Minivols, but that is prohibitively expensive. If we could use 3 XADs sampling simultaneously with the 6 Minivols and rotate the XADs between locations on the 3 different sampling days, we would be in good shape. If that is not in the realm of budget reality, we should run at least 2 XADs simultaneously, rotating through the locations. These options give us the following budget numbers: Most rigorous 6 Minivol samplers + 3 XAD samplers = $16,307.73 in sampler rental So, Total DRI costs ($41,873.61) + My budget ($17,020) = Total budget: $68,883.61 6 Minivol samplers + 2 XAD samplers= $13,059.26 in sampler rental Total DRI costs ($38,625.14) + My budget ($17,020) = Total budget: $55,645.14 Less rigorous 3 Minivol samplers + 2 XAD samplers= $9,778.10 in sampler rental Total DRI costs ($35,343.98) + My budget ($17,020) = Total budget 52,363.98 (but still scientifically defensible) This is probably more information than you really wanted, but I want you to have enough background to explain it in the meeting. February 9, 2009 RE: Literature review and monitoring proposals to assess potential environmental impacts of aircraft emissions at John Wayne Airport Orange County, California Dear Mr. Bludau: I am pleased to submit the final draft of my report "Literature review and monitoring proposals to assess potential environmental impacts of aircraft emissions at John Wayne Airport Orange County, California ". This document provides research options for investigating the effects of aircraft emissions on environmental and human health near John Wayne Airport, and summarizes scientific literature relevant to this question. The report and accompanying budget worksheet provide enough detail for the City of Newport Beach to select individual sampling or experimental protocols which best meet their research priorities. My recommendation for a baseline data set would be to combine basic air sampling with experimental microcosms testing: toxicity, invertebrate bioaccumulation and environmental fate. Additional testing could be added as funding allows, or to pursue findings of interest in the baseline data set. Depending upon when the City decides to commence monitoring and the option(s) that it chooses, the anticipated time line for completion of the project and analysis of the data is approximately six (6) to nine (9) months. If you would like assistance to modify the scope of research to meet a specific budgeted amount or to focus on different research questions, I will be happy to tailor it to your needs. Please feel free to contact me with any questions or comments. Respectfully Submitted, Karleen A.
