READ FIRST TIME 02/13/17.





1       AN ACT Relating to directing the completion of a study of certain
2   environmental  impacts,  including  ultrafine  particulate  emissions,
3   associated  with  aircraft  traffic  in  areas  impacted  by  airport
4   operations; adding a new section to chapter 70.94 RCW; and providing
an expiration date.5
6   BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:
7       NEW SECTION.   Sec. 1.   A new section is added to chapter 70.94
RCW to read as follows:8
9       (1) The  department  of  commerce,  in  consultation  with  the
10   department of health and the department of ecology, is directed to
11   complete  a  study  by  September  1,  2019,  regarding  air  quality
12   implications  of  air  traffic  at  the  international  airport  in
13   Washington  with  the  highest  number  of  total  annual  departures  and
arrivals.14
15       (2)(a) The study must consist of an assessment, to be completed
16   by  the  University  of  Washington  school  of  public  health,  of  the
17   concentrations  of  ultrafine  particulate  matter,  barium,  aluminum,
18   radioactive  thorium,  cadmium,  chromium,  and  ethylene  dibromide  in
19   areas surrounding and directly impacted by air traffic generated by
20   the airport. For purposes of this section, the areas near the airport
21   that are described as the focus of various components of the study
p. 1                         SHB 1171

1   and  the  potential  second  phase  of  the  study  must  encompass  areas
2   within ten miles of the airport in the directions of aircraft flight
3   paths and areas within ten miles of the airport where public agencies
4   operate an existing air monitoring station. The assessment must:
5       (i) Monitor and evaluate the concentrations and characteristics
6   of ultrafine particulate matter and the substances listed in (a) of
7   this subsection in areas impacted by high volumes of airport traffic,
8   including   the   patterns   of   spatial   distribution   of   ultrafine
9   particulate  matter  and  the  substances  listed  in  (a) of  this
10   subsection. To the extent practicable, the assessment must attempt to
11   distinguish between ultrafine particulate matter and the substances
12   listed in (a) of this subsection that is attributable to aircraft
13   sources and ultrafine particulate matter and the substances listed in
14   (a) of this subsection that originates with other sources;
15       (ii) Compare concentrations of ultrafine particulate matter and
16   the substances listed in (a) of this subsection in areas surrounding
17   or  directly  impacted  by  high  volumes  of  airport  traffic  against
18   concentrations  of  ultrafine  particulate  matter  and  the  substances
19   listed  in  (a) of  this  subsection  in  locations  in  the  ambient
20   environment  that  share  similar  characteristics,  but  that  are  not
21   surrounding or directly impacted by high volumes of airport traffic;
and22
23       (iii) Analyze the gaps and uncertainties in health information
24   associated  with  ultrafine  particulate  matter  and  the  substances
25   listed in (a) of this subsection and whether sufficient information
26   is available to support a second phase of the study described in (b)
27   of  this  subsection  being  completed  in  a  manner  that  provides
informational value.28
29       (b) The  department  of  commerce  must  coordinate  with  local
30   governments in the areas addressed by the study to share the study
31   results and to solicit public feedback in a manner that is inclusive
32   of  community  members.  The  department  of  commerce  must,  after
33   evaluating  the  results  of  the  study  in  (a) of  this  subsection,
34   consider whether to recommend proceeding with a second phase of the
study, which would include:35
36       (i) An analysis of options to reduce or mitigate emissions or
37   public  health  impacts  of  ultrafine  particulate  matter  and  the
38   substances listed in (a) of this subsection from aircraft, including
39   but not limited to the use of alternative fuel sources or particulate
40   filters  by  aircraft,  building  insulation,  air  filtration,  and
p. 2                         SHB 1171

1   education.  In  evaluating  emission  reduction  or  mitigation  options,
2   the department of commerce must consider the anticipated costs and
3   feasibility  of  each  option,  including  the  potential  role  of  the
federal aviation administration;4
5       (ii) An  analysis  of  the  rates  of  exposure  to  ultrafine
6   particulate  matter  and  the  substances  listed  in  (a) of  this
7   subsection  by  low-income  residents,  communities  of  color,  senior
8   citizens,  port  employees  who  work  at  the  airport,  and  other
9   communities  that  may  be  disproportionately  impacted  by  ultrafine
10   particulate  matter  and  the  substances  listed  in  (a) of  this
11   subsection pollution. This analysis must consider public health data
12   maintained by the department of health or local health jurisdiction,
to the extent such information is available;13
14       (iii)  An  analysis  of  the  scope  of  risks  posed  by  ultrafine
15   particulate  matter  and  the  substances  listed  in  (a) of  this
16   subsection  air  pollution  in  communities  adjacent  to  and  directly
17   impacted by the airport and air traffic in both absolute terms and
18   relative  to  the  risks  posed  by  other  types  or  sources  of  air
19   pollution  or  other  pathways  of  exposure  to  pollutants  in  the
environment; and20
21       (iv) An  analysis  of  other  direct  and  indirect  environmental
22   impacts to the areas surrounding the airport that are attributable to
23   increased  volumes  of  air  traffic,  including  noise  pollution,
aesthetic impacts, and the loss of habitat.24
25       (3) Consistent  with  RCW  43.01.036,  the  department  of  commerce
26   must report its findings from the study to the appropriate committees
27   of the legislature by December 1, 2019. The report must include a
28   summary  of  findings  on  the  prevalence  of  ultrafine  particulate
29   matter, barium, aluminum, radioactive thorium, cadmium, chromium, and
30   ethylene  dibromide  pollution  in  areas  surrounding  and  directly
31   impacted  by  the  airport,  and  a  recommendation  regarding  whether
32   sufficient   ultrafine   particulate   matter,   barium,   aluminum,
33   radioactive  thorium,  cadmium,  chromium,  and  ethylene  dibromide
34   information is available to validate proceeding with a second phase
of the study.35
(4) This section expires June 30, 2022.36
