I. Emission Sources On and

Adjacent to the Tulalip Indian Reservation

SLIDE 13

On-Reservation/Local Emission Sources

 Outdoor burning (residential, land-clearing

perations, forestry management)

 Residential wood combustion

(predominantly woodstoves)

 On-road mobile sources (unpaved gravel

roads, 2-lane highways, interstate)

 Off-road mobile sources (marine engines)  Minor sources

SLIDE 14

SLIDE 15

Off-Reservation Area Sources

 Interstate 5  Marine - Port of Everett (deepwater bay

n Puget Sound)

 Rail – Burlington Northern  Residential wood combustion

(woodstoves and fireplaces)

 Permitted facilities

SLIDE 16

2009 Emissions Inventory

 Marine vessel emissions  Woodstove emissions  Outdoor burning emissions  Stationary facility emissions  Mobile emissions

II. Community Concerns

SLIDE 20

SLIDE 21

Asthma in native populations (as in many ethnic groups) is the product of underlying health, environmental and cultural disparities.

SLIDE 22

 High incidence of RSV (respiratory virus) in

AI/AN infants and children, which is recognized as a

factor in triggering the onset of asthma later in childhood (1).

 Certain non-respiratory conditions, such as

diabetes and high blood pressure, are statistically higher in AI/AN communities, and are associated with an increased risk of premature stroke or heart attack during episodes of poor air quality(2). Health Disparities

SLIDE 23

 Allergic Diseases: Eczema, Hay

Fever, Chronic Rhinosinusitis

 Respiratory Diseases: Asthma,

Chronic Bronchitis, Emphysema

 Pulmonary Disease: Hypertension  Inflammatory Diseases: Diabetes

III. Emissions and

Human Health Implications

SLIDE 25

Surface area of lungs is equal to the total surface area
f a tennis court
Greater than 100 sq yards
80 times the surface area of your skin

SLIDE 26

Blue columns represent the smallest parts of the lungs, called first-generation bronchioles, where fine PM is trapped. The graph illustrates the increase in airway damage at this level, where pollutants cannot be effectively cleared from the airways through normal mucosal or cilliary movement.

SLIDE 27

SLIDE 28

Tracking data ties increase

in fine PM (short term) to acute health outcomes… artery constriction which leads to cardiovascular events (stroke and heart attack)

Fine particles produce

pollutant-induced oxidative stress, which may accelerate remodeling

RESPIRATORY DISTRESS AND ACUTE HEALTH OUTCOMES DIRECTLY ASSOCIATED WITH AIR QUALITY

SLIDE 29

IV. Mechanisms for Addressing Air

Quality at Tulalip

SLIDE 30

 Ambient Air Quality Monitoring (PM2.5)  Enforcement of Outdoor Burning Regulations

(Tribal Code and Federal Air Rules for Reservations)

 Targeted Emissions-Reduction Initiatives

(Fishing Vessel Repower Project – 2012)

 Education and Outreach
