SUMMARY

The Seattle Tacoma International Airport currently has no air-pollution

monitoring system in place. The Washington State Department of

Ecology (DOE) studied how seriously the airport is affecting the quality

of the air we breathe.



The Seattle Tacoma International Airport covers 2500 acres of land in

King County.  This a mere 0.18% or less than 1/5 of 1% of the land in

King County.  The DOE found that Sea-Tac Airport contributed 8% of the

carbon monoxide and 5% of the nitrogen oxide emissions in all of King

County in 1991.



The following air pollutants, classified as either Criteria or Toxic

Pollutants, are not being monitored by Sea-Tac Airport staff:

Total suspended particulates, particulate matter, carbon monoxide,

oxides of sulfer, oxides of nitrogen, hydrocarbons, ozone and lead

(criteria pollutant) Phenyl, benzene, dioxin, toluene, manganese, xylene,

formaldehyde and chloroform pc.,[Ed. note: unreadable text]. Benzene,

one of the toxic pollutants, is a known carcinogen.  Sea-Tac airport,

according to the DOE study, contributed 12.7 tons of benzene in 1984.

This amounted to about 0.16 parts per million or 24,000 parts per trillion.

New WAC 173-460 proposes the acceptable impact levels for benzene

at 0.063 parts per trillion.





There is no baseline for a study of air pollution at the Seattle-Tacoma

International Airport.  There is no system set up at this time to study air

pollution.  This is a fatal flaw in the [FlightPlan] Environmental Impact

Statement which must be corrected.



Airport currently has no air-pollution monitoring system in place.



[Page 3]

Our creation of agents of pollution such as chlorofluoro-

carbons has resulted in by-products which are destructive to the

beneficial ozone layer of the stratosphere.[Footnote 1]  This beneficial

ozone layer protects all forms of life from the harmful ultra

violet B (UVb) rays of the sun.  Excess UVb radiation can cause

cataracts, mutations in DNA which lead to skin cancers (including

the often deadly melanoma).  Excess UVb rays can also threaten

the yield of the world's basic crops.  UVb rays penetrate

below the surface of the oceans, killing phytoplankton and krill

which nourish larger fish and ultimately humans.[Footnote 2]  The United

Nations Environment Program predicts a 26% increase in the

incidence of nonmelanoma skin cancers worldwide if ozone (03)

levels drop by 10%.[Footnote 3]  Furthermore, excess UVb radiation affects

the body's immune system, although to what extent has not been

determined.



Trophospheric ozone is an air contaminant and must be

controlled.[Footnote 4]   It is produced in two different ways: Non catalytic

reactions involving nitrogen dioxide (NO2) and light, and by catalytic

production involving hydrocarbons.[Footnote 5]



[Page 4]

The  Seattle-Tacoma International Airport is the focus of

debate because of the perceived need to expand.  Sea-

Tac is located on 2500 acres in King County which contains 2130.9

square  miles, and 640 acres equals one square mile. [Footnote 7]  Simple

computation shows that Sea-Tac occupies a mere 0.18% of  the land

in King County -- or less than 1/5 of 1%.[Footnote 8]



What  is the airport's contribution to air pollution in King

County?  This tiny pinpoint of land "contributes 8% of the carbon

monoxide   and   5%  of  the  nitrogen  oxide  emissions  in

Kirig County".[Footnote 9]    This concentration of air pollutants, reflected

in  the  study requested by State Representative Greg Fisher,  (D,

33rd  District) has not been followed up by the staff  at  Seattle

Tacoma International Airport.  Airport staffers are still "lookina

into", the problem.  There is still no baseline and no Process  in

Place to study air quality at the airport.



The October 2, 1992 editions of the Seattle Times

and the P.I. carried a story about the Center for Disease

Control's (Atlanta, Ga.) investigation into the increase of deaths

from asthma.  Air pollution is one of the factors under indictment

as a cause of asthma. In a talk with community



[Page 5]

members on  September 10, 1992, Dr. Gordon  Baker, an allergist

practicing in Burien, Washington said he found 34% of his patients

with asthma residing in 4% of zip codes closest to Seattle Tacoma

International Airport.



What cumulative effect occurs from all known sources of  air

pollution  in  the  Puget  Sound  region,  between  the  Cascade

Mountains and Puget Sound?  This region is severely impacted by

many sources of pollutants.  These sources include but are not

limited to:  shipping, air transportation, ground transportation,

freight -- trucks and rail -- personal wood burning (indoors and

outdoors),  construction burns, logging burns, as well as commercial

and  industrial emissions and all kinds of leisure activity

equipment and tools which utilize petroleum products.



    Many of  these sources of pollutants, such as aircraft, are

included in a difficult to measure category because they are

mobile sources.  The Department of Ecology has certain specified

regions in Washington State where accumulations of air pollutants

can be ascertained and evaluated  geographically. These

mobile sources of pollutants are included in the category of

"other sources"[Footnote10] but there are no documented cumulative and

compounded effects of these mobile sources.



This paper will concentrate on pollutants registered in six

counties of Western Washington in regions identified by the

Washington State Department of Ecology: Snohomish, King, and



[Page 6]

Pierce Counties in the Puget Sound Region and Thurston, Whatcom

and Skagit Counties in the Olympic-Northwest Region. [Footnote 11]



Air pollution is commonly divided into two major categories:



CRITERIA AND TOXIC POLLUTANTS



Criteria Pollutants consist primarily of  the following elements: Total

suspended particulates (TSP), particulate matter (PM10), carbon

monoxide, oxides of sulfur, oxides of nitrogen, hydrocarbons,

ozone and lead (Pb).  These criteria pollutants are constantly monitored

365 days per year by the Department of Ecology (DOE). However, Sea-

Tac Airport has no process for monitoring criteria or toxic pollutants.



TOXIC POLLUTANTS



Toxic air pollutants are colorless and odorless.  Unfortunately, toxic air

pollutants  are not yet regulated. Among the hundreds of  chemicals are

phenyl, benzene, dioxin, toluene, manganese, xylene, formaldehyde and

chloroform.   Not only are these pollutants toxic, many are known

carcinogens. However, increasing attention is being given to them

because of the potential effect to human health. In 1988, DOE began

the process to regulate air toxins.  In 1990, DOE started the laborious

task of identifying and evaluating various toxic control strategies.



CRITERIA  POLLUTANTS



Criteria pollutants --carbon monoxide, nitrogen dioxide, sulfur dioxide,

ozone, particulates, hydrocarbons and lead --



[ Page 7]

are common air pollutants and have been shown to be harmful to

human health and welfare.[Footnote 12]  Criteria pollutants are regulated

according to federal and state levels. Monitoring of criteria

pollutants is constant.



Carbon monoxide (CO) is deadly in high concentrations.

It is the cause of many deaths. CO is a colorless, odorless gas

and is the most frequently monitored component of air polIution.

CO binds to the hemoglobin in the bloodstream and replaces the

oxygen molecules reducing the blood's potential to carry oxygen

throughout the body.  This reduction in the body's ability to

transport oxygen throughout the body has been found to cause heart

difficulties in people with chronic diseases.  It also reduces lung

capacity which may aggravate arteriosclerosis.[Footnote 13]

Lack of oxygen has also been found to be a cause of impairment to

mental abilities.[Footnote 14]  Carbon monoxide is not monitored at Sea-

Tac.



Mobile sources which emit carbon monoxide and other

pollutants are not fully monitored.  Personal and business

vehicles which rely on gasoline are monitored in much of the Puget

Sound region and during the colder months of the year are required

to run on oxygenated gas.  Vehicles which use diesel



[Page 8]

fuel are not as stringently monitored.  Jet aircraft are under the

jurisdiction of the FAA and are beyond Washington State's

demanding regulations.



The primary standard for CO is 35 parts per million (ppm) for

one  hour and 9 ppm for 8 hours. The Puget Sound region and the

Southwest  Region exceeded these standards in 1989 six times in

four  months.    In 1990, standards were exceeded four times in

three  months.[Footnote 15]  The Puget Sound region is in  nonattainment  for

carbon monoxide, particulate matter and ozone.[Footnote 16]   Nonattainment

is defined as exceeding the standards 5et by Washington State.



Particulates are classified in two ways:   total suspended

particulates (TSP) which are composed of particles of 10 microns

(about  the  size of a human hair) or less in diameter and parti

culate matter (PMio) which consists of tiny particles of dust,

sand, cinders, soot, asbestos, smoke and liquids found in the

atmosphere.   Suspended particles aggravate  chronic disease and

heart  and lung disease symptoms.  TSP and PMio often  transport

toxic  elements such as lead, cadmium, antimony, arsenic, nickel,

vinyl chloride, asbestos and benzene compounds throughout the

body, often ending up in the respiratory, digestive and lymphatic

Systems.[Footnote 17] Particulates are not monitored at Sea-Tac.



[Page 9}

Adverse effects of both SPand PMio are the aggravation of

chronic disease5 and heart and lung disease symptoms."[Footnote 18]

In the Puget Sound and Olympic-Northwest Regions TSP and PMio come

from many different sources:  roads, fields, construction

sites, factories, power plants, fireplaces, wood-burning stoves,

windblown dust, diesel and car exhaust, ferry traffic, shipping

and the region's numerous (two dozen plus) airports.



King County has begun regulating particulates from several

sources:  outdoor burning at all times; restricting the use of

wood-burning stoves and fireplaces during specific weather condi

tions; and requiring gasoline powered automobiles to have emission

tests  every  two years in order to be relicensed.  Unfortunately

many sources of criteria pollutants remain unaffected from such

stringent  requirements: aircraft, diesel-fuel burning vehicles,

shipping, ferry traffic, off-road vehicles such as snomobiles and

all  kinds of other leisure-activity equipment including  jet-

skis, lawn mowers, blowers, etc.



Washington  State has set standards for TSP at 60 micrograms

per cubic meter.[Footnote 19]   Aircraft are regulated by the FAA, not the

State of  Washington.  In the regions being  assessed, TSP

standards were exceeded in the following months of 1990:

February, April, May, July, September, October, November and



[Page 10]

December.  Fortunately, the amounts of TSP appear to be

decreasing since monitoring in the regions began.[Footnote 20]



The Puget Sound region (Everett-Seattle-Tacoma) is designated

as a "non attainment" area for carbon monoxide, ozone, particulate

matter (PMlo) and total suspended particulates.[Footnote 21]



Oxides of sulphur (SO2 and S03) become acidic by reacting

with  the moisture in the atmosphere.  This creates a mist (,acid

rain) which damages the leaves and needles of trees and

eventually kills the forests.  Sulphur dioxide is known for

its pungent, irritating odor and suffocating quality.



The oxides in the air we breathe must be filtered from the

air to protect our respiratory system.  Our sinuses are the

filters of our bodies, and they are working overtime.



Sulphur dioxide particles and other inorganic sulphates

penetrate the mucosal lining and are intensely irritating to the

bronchial mucosa, damaging the cilia and initiating bronchitis,

producing asthma which decreases human respiratory function both

at the acute and chronic levels.  Exacerbation of other lung

diseases also occurs.[Footnote 22] S02 also aggravates symptoms of  heart

disease.



[Page 11]

S02 standards set by Washington State are 0.02  ppm as an

annual average, 0.10ppm 24 hour average and a 0.40 ppm for one

hour.[Footnote 23]  According to the DOE, annual standards are never to be

exceeded and short term standards are not to be exceeded more than

once  Per Year unless noted.  There were no documented exceedences

during 1990 in the parts of the regions reviewed for this paper.  S02 is not

monitored at the airport.



Nitrogen oxides provide color to the cloud of air Pollution.  They result

from the high temperature oxidation of the nitrogen present in the air.

Nitrogen oxides form particulates by coalescing into larger segments which

reduces visibility and contributes to acid deposition.  Nitrogen dioxide

(NO2) is the most prevalent of the nitrogen oxides.



N02 is a yellowish brown, highly poisonous reactive gas.  N02

forms when fuel is burned at high temperatures.  It is used as an

intermediate in the manufacturing of nitric and sulferic acids.

Internal  combustion engines (automobiles and aircraft) and

stationary fuel combustion sources are the two major sources of

nitrogen oxide.  N02 has a primary standard of 0.05 ppM.[Footnote 24]



N02 increases the incidence of chronic bronchitis because  it

is  a  bronchoconstrictor.[Footnote 25] N02 causes lung irritations resulting

in ciliary paralysis,  bronchitis and pneumonia.   N02



[Page 12]

exacerbates influenza by impairing the body's immune defenses

against bacterial and viral infection.[Footnote 26]   Nitrogen oxides are

also factors in the generation of secondary pollutants such as

ozone.  Both ozone and N02 impair humans in very similar ways.

This is why the air pollution equation of compounding and

cumulative effects of these pollutants needs to be thoroughly

researched before more pollutants are added.  There is no

monitoring of N02 at Sea-Tac Airport.



Hydrocarbons result from the release of unhurried fuel or

incomplete combustion of fuel.  Internal combustion engines

(automobiles and aircraft) are a primary source of hydrocarbons

which play an important role in determining air quality.

Other sources of HC emissions are the result of industrial

processes, industrial and household solvents and fuel transfers.



Fuel misting by aircraft occurs mostly during takeoff and

landing.   This is because aircraft emit small quantities of

unburned fuel containing hydrocarbons and particulates from the

exhaust ports of  jet engines.  There is an intense odor when these

episodes occur.  "These emissions occur during takeoff and landing and

are most noteable near the ends of the runways." [Footnote 27].  Fuel

venting occurs mostly during an emergency, when fuel is jettisoned.



[Page 13]

Hydrocarbons mix with oxides of nitrogen in the presence of

sunlight to form both ozone and N02.  The amounts of hydrocarbons

released increase ozone levels more than any other pollutant.[Footnote 28]

Hydrocarbonsare highly irritating to the mucous membrane and make

a  generous contribution to upper respiratory distress.[Footnote 29]  The

compounding effects of N02, ozone and hydrocarbons on the entire

earth's system must be researched.     Each individual pollutant

may not be harmful in small doses, but the compounding of all

these pollutants and the cumulative effects are basically unknown

because each is studied independently,



Ozone is found iri two regions of the earth's atmosphere: the

troposphere  and  the  stratosphere.  Ozone in the lower,

breathable part of the atmosphere (troposphere) is produced when

sunlight acts upon nitrogen oxides and hydrocarbons, producing N02

and  ozone.  This ozone is highly toxic and is regulated and

monitored.   Exposure to ozone "results in  eye  irritation  and

Oamage to lung tissues, reduces re--istance to colds and

pneumonia, aggravates heart disease, asthma, bronchitis and

emphysema."[Footnote 30]  Stratospheric ozone is beneficial because of its

protection against the UVb rays of the sun.



[Page 14]



The beneficial ozone is attacked by chlorine atoms from the

chlorofluorcarbons (CFC'5). CFC'5 take one oxygen atom away from the

ozone to form chlorine monoxide.  [Footnote 31] The chlorine monoxide

then combines with another oxygen atom to form a new oxygen molecule

and a chlorine atom. The process can go on indefinitely.  In fact, "each

atom of chlorine . . . could destroy up to 100,000 molecules of ozone."

[Footnote  32] This results in the destruction of the beneficial

stratospheric layer of 03 and leads to global warming.  Human health

effects due to the breakdown of the stratospheric layer of 03

include increased mortality in the elderly and very young populations

due to heat stress, increased preterm and prenatal births and increased

diseases carried by fleas, ticks and mosquitoes. [Footnote 33]





The  newly  formed  oxygen molecules do not block the ultraviolet light,

but allow it to penetrate to the surface of the earth where it is harmful to

human and animal health, crops and forests. Although ozone is the air

contaminant for which standards are set, its precursors (HC and NOx)

are the pollutants which must be controlled.  [Footnote 34] Areas with

the worst ozone pollution are also those areas with the largest

populations and served by the largest airports:



[Page 15]

Southern  California, the Northeast, Texas Gulf Coast and  Chicago

Milwaukee.  Cities in California with the worst ozone pollution

are  Los  Angeles-Long Beach, Riverside-San Bernardino and Anaheim

Santa Ana. [Footnote 35]



The Seattle-Tacoma-Everett area with major shipping ports,  a

major  international airport and over two dozen smaller  airports,

heavy  road  traffic, industry, large and small businesses  has

exceeded the primary standards for ozone levels of 0.12 ppm for a

one-hour period in 1990 (two days in  July and two days in

August.) [Footnote 36]   The same area was declared as an Ozone Nonattainment

Area  in 1988, Ozone standards were exceeded in 1990 on

three separate days at the monitoring site in Enumclaw.  Because

of these exceedences, the area will not be able to comply with the

standard  before late 1993 or early 1994.  This assumes that

the average of  he three years is less than one exceedance per

year.  The Seattle-Tacoma-Everett area must attain the ozone

standard no later than November 15, 1993. [Footnote 37] (see attachment) [Ed note: attachment

not available at this time.]



Growing  scientific evidence indicates that ozone is a

significant risk to human health.  It appears to affect healthy as

well as impaired respiratory systems in children and adults.

Although no direct research on ozone and the sinuses has been

done, the Air Pollution Health Effects Laboratory, University of



[Page 16]

California, Irvine has studied the effects of ozone on the nasal

cavities of rats.  Their findings of significant damage to the

mucous membrane surrounding the opening to the maxillary sinuses

as  a  result of inhaling ozone lends substance to the theory that

ozone  also damages the 5inuses. [Footnote 38]    A recent study of  ten and

eleven year olds in Los Angeles shows lung capacity has

diminished 17% compared to the normal range. [Footnote 39]    Autopsies

performed by a pathologist at the University of Southern

California on accidentally killed children show a "disturbing

frequency of emphysematous changes previously seen only in adult

lungs." [Footnote 40]   "Ozone can also cause shortness of breath and

coughing during exercise in healthy adults and more serious

effects in the young, old and infirm". [Footnote 41]   Monitoring for Ozone

does not occur at Sea-Tac Airport.



Lead is an abundant metal.   It is not readily excreted

and therefore accumulates in the body within the blood, bones and

soft tissue.  Lead affects the kidneys, nervous system and blood

forming  organs.   Excessive exposure may cause  nervous system

impairments: seizures, mental retardation, behavioral disorders,

miscarriages, stillbirths and defects of the newborn.  Lead may



[Page 17]

also contribute to high blood pre--sure and sub--equent heart

disease.[Footnote 42] Lead is not monitored at Sea-Tac Airport.



Standards to protect the public health have been set by the

Federal Clean Air Act.  These standards use conclusive scientific

and  technical information available at the time the standards are

set.   They are set to provide a reasonable degree of protection

from hazards that scientists may not have identified.



Air pollutants which affect the biota can also accelerate the

deterioration of property, cause changes in economic values and

become a threat to the quality of life.[Footnote 43]   Because air

pollutants drift downward and settle in the soil, even those who

buy "organic" food are impacted by chemicals.  The food chain

contains many chemicals which are harmful to our bodies.  The

food we eat may contain minute levels of toxic chemicals, but the

compounding effect of all these chemicals can be disastrous.



Researchers (Falck, et al) analyzed fatty tissue from the

breasts  of 40 women, 20 of whom had cancerous lumps and 20 had

benign lumps.  In the fatty tissue from the breasts, Falck, et al

found significantly higher levels of the extremely long lived and

stable chemicals DDT, DDE and PCBS.  Their conclusion is that  the

chemicals in the food and animal fat (fish, fowl and meat)

accumulate in the fatty tissue.[Footnote 44]



[Page 18]

Because of the implication that criteria air pollutants

jeopardize human health, ongoing studies must continue.   Sea-Tac

Airport staff must be forced to begin the Process of monitoring

its own air pollution.



                        TOXIC  POLLUTANTS

Toxic pollutants have generally not been subjected to

rigorous scientific studies and are not highly regulated at this

time.  However, increasing attention is being given to them

because  of the potential effects on human health.  These include

but are not limited to the following toxic pollutants:

phenyl, benzene, dioxins, toluene, manganese, xylene, chloroform

and  formaldehyde. [Footnote 45]   The Department of Ecology is concerned

about  exi--ting toxic air pollutant sources.  These sources

generate complex control issues and pose great health risks to the

general population.



Many of the toxic pollutants are known carcinogens with no

set standards for an "acceptable level" to human, animal or plant

health; however, there are industrial standards set for products

which contain hydrocarbons and toxins.



Benzene is one of the more dangerous toxic pollutants.

it is a known carcinogen.  It is about 4% of hydrocarbon

emissions.  In 1934, the Radian Corporation estimated that roughly

12.7 tons of benzene were emitted at the airport.[Footnote 46]  Further

estimates by



[Page 19]

the Radian Corporation are that the hourly average contribution of

benzene at Sea-Tac airport is about 0.16 parts per million (or an

average of 24,000 parts per trillion annually). [Footnote 47] New WAC

173-460 proposes the acceptable impact levels for benzene at 0.063

parts per trillion. [Footnote 48]  How will the airport manage to reduce

benzene to acceptable level?



At  the airport, toxic pollutants are measured in metric ton-

per day, but a published baseline for 1992 is hard to find (if  it

exists.)  A metric ton is 2204.62 avoirdupois pounds which  is

equivalent to 1000 kilograMs. [Footnote 49]



The Flight Plan Project Final Environmental Impact Statement

projections for these toxic pollutants begins with the year 2000

and goes through 2010 to 2020.  Where is the 1992 baseline

for toxic pollutants in the Puget Sound region?



Anecdotal evidence points to a greater frequency of  many

kinds of cancers in residents close to Sea-Tac Airport.  Therefore,

in the words of Dr. Michael Morgan, hired as a consultant

 to the Flight Plan committee:

     "THE   CLAIM   OF  CANCER  CASES  AT  HIGHER  THAN   EXPECTED

     FREQUENCIES  AROUND  AIRPORTS  CANNOT  BE  DISMISSED  WITHOUT

     SYSTEMATIC INVESTIGATION." [Footnote 50]



[Page 20]



In 1987, Swedish dentists studied persons who had worked at

an airport at some time in their adult lives.  These workers had a

greater  frequency of brain cancers than persons matched for

characteristics other than brain cancer. [Footnote 51



Toxic air pollution emissions in the entire Puget Sound Region

must be determined on a cumulative and compounded level.

There seems to be no plan to diminish criteria and toxic air

pollutants from mobile sources other than internal combustion

engines which are fueled by gasoline.   Diesel and jet fuel

sources are immune from these regulations.  The contribution

of emissions from the airport is viewed as inconsequential.

Unfortunately, jet aircraft emissions permeate the atmosphere and

leave residue on residential and business properties, in our

lungs, on the ground and in the water.



QUANTITY OF EMISSIONS THROUGHOUT THE REGION

The Flight Plan Project was charged with identifying the

amounts of emissions of air pollutants for the three airport

system. This effort failed to take into consideration the CUMULATIVE

AND COMPOUNDED effect of all emissions on the entire

region.  It is difficult to extrapolate from the information given in

the Flight Plan Final Programmatic EIS how severely the

region  would  be  affected by any of the alternatives. [Footnote 52]

Sea-Tac is a "major indirect source of carbon monoxide, hydrocarbons,



[Page 21]

fine  particulates and nitrogen oxides most of which are generated

by aircraft operations and motor vehicle traffic". [Footnote 53]   Aircraft

emission standards are implemented by the FAA.  Washington State

and  the Environmental Protection Agency have no ability to apply

standards to the airport or the aircraft. [Footnote 54]



The Department of Ecology (DOE) has determined that carbon

monoxide and hydrocarbon emissions generated by aircraft at SeaTac

Airport occur in significant numbers when aircraft queue for take

off and in taxiing in and out. The standard used by DOE for

determining the amount of emissions is in metric tons.  A metric

ton (2204.62) is over 10% more than commonly used 2000 pound ton.



Carbon monoxide emissions total 1800 metric tons per year;

hydrocarbon emissions are about 800 metric tons per year. [Footnote 55]  Climb

and approach figures for CO and HC are 400 and 100 metric tons per

year respectively. [Footnote 56]



Nitrogen oxide emissions are1200+ metric tons per year for

climb and approach, 500 metric tons/year for takeoffs, 175 metric

tons/year for queues and 100 metric tons/year for taxiing in and

OUt. [Footnote 57]   Nitrogen oxides in aircraft exhaust generally oxidize to

N02 and disperse over a wide area, reducing concentrations



[Page 22]

around the airport.  It is probable that other pollutants

disperse as well.



Sulphur oxide emissions are 900 metric tons/year when aircraft

are in climb and approach, 40 metric tons/year while in a

queue,  20 metric tons/year on takeoff and 20 metric tons/year

taxiing in and out.[Footnote 58]



 Particulate emissions are 34 metric tons/year in climb and

approach, 13 metric tons/year in queues, ten metric tons/year  on

takeoff and 9+ metric tons/year taxiing. [Footnote 59 ]   These numbers must

be added together to find the true impact of air pollutants

generated by Seattle-Tacoma International Airport's business.



Aircraft at Sea-Tac produce 3,050 metric tons per year of

carbon monoxide emissions, 1300 metric tons/year of hydrocarbon

emissions, 1950 metric tons/year of nil.rogen oxide, 175  metric

tons/year of sulfur oxide and 68 metric toris/year of particulate

emissions.  Compare these figures with motor vehicle emissions at

the  airport of less thari 600 metric toris/year of all pollutants

combined.  (Figures have been totalled by estimation from  graphs

presented  on  pages  18 and 19, figures 4 -  8, SEATTLE TACOMA

INTERNATIONAL AIRPORT: Air Pollutant Contribution.)  Add 10% more

to each of these figures to determine the impact: 6555.70  metric

tons or 7211.27 tons per year.



[Page 23]



It is difficult to address all factors of air pollution with limits to

amount of time and resources.  I have not addressed the

geophysical attributes nor weather patterns in this paper.

However, both are important factors in air pollution monitoring.

The region lies between two mountain ranges, contains large

bodies of both salt and fresh water and has smaller plateaus and

valleys.   All these physical characteristics play an important

part  in air movement.  Wind, rain, sun, snow, fog or the lack of

these also impacts how, when or if the pollutants disperse and  to

where,   Dispersal  does not mean the pollutants disappear.

Many of them remain with us far too long.



"Our environment is not infinitely resilient" and neither are

we.  "For  too long we have assumed dominion over the

environment and have failed to understand that the earth does not

belong to us, but we to the earth." [Footnote 60]



CONCLUSION



     We  must remember that chemical pollution threatens all forms

of  life.  The serious effects of air pollution to this planet

must be considered.   We cannot always wait until there is

indisputable evidence that serious damage is occurring before we

try to halt the damage.  The cumulative and compounded effects of

air pollution is just one of the many dangers which can be avoided

if  there  are  monitoring safeguards for all forms of  polluters.

Aircraft and diesel burners (trucks, ships, cars,



[Page 24]

furnaces,  etc.)  must  have regulations  which  provide  for  the

capture  and  safe  destruction of pollutants  thereby  preventing

contaminants from being released into the air.



    Automobiles which use gasoline are regulated and monitored.

We  must do the same for all other emission producers.  It is not

enough to point the finger at only one part of the problem, such

as private  vehicles, forcing these owners to comply with regulations

when other sources are allowed to continue to pollute.   All

sources must be required to be clean.  Special attention must be

given to relatively small areas like Seattle-Tacoma International

Airport with unacceptably high pollutant concentrations.  We  must

be assured that such areas grow no worse as time progresses.

IT IS IMPERATIVE THAT THE STAFF AT SEATTLE-TACOMA

NTERNATIONAL AIRPORT BEGINS TO DOCUMENT THE

AIRPORT'S AIR QUALITY WITH THE BEST AVAILABLE

TECHNOLOGY, NOT THE LEAST EXPENSIVE.
