Fine Particulate

National

Ambient

Afr Quality Standard Dear

Dr. Cripps: The

U.S. Environmental

Protection

Agency

(EPA) promulgated

a revised primary

annual National

Ambient

Air Quality Standard (NAAQS)

for fine particulate

matter

(PM 2

) on December

14, 2012

(78

FR 3086, January

15, 2013). Pursuant

to Section

107(d)

of the Clean

Air Act,

the governor

of each

state

is

to recommend

area designations

to the EPA whenever

a NAAQS

is established

or revised. The Washoe

County

Health District,

Air Quality Management

Division (WCAQMD)

monitors

PM 2 . 5

at two sites (Reno

(AQS

ID 32-031-0016)

and Sparks

(AQS

ID 32-031-1005)),

which

are both located

in Hydrographic

Area

87

as defined

by

the State

of Nevada Division

of Water Resources.

Data

from

these

two sites

were complete,

quality assured,

and reported

in accordance

with

40 CFR

50.8.

Only

one year

of PM 2 . 5

data are available

from

the Sparks

site because monitoring

began

in 2012.

It

is included

in the attachment

for reference. Based

on guidance documents

from

Gina McCarthy

(Assistant Administrator

for

the EPA Office

of Air

and Radiation)

dated

April

16, 2013,

the WCAQMD recommends

that: 1. Hydrographic

Area

87

of Washoe

County

be designated

as

an “attainment”

area

and 2.

The remaining 1-lydrographic

Areas

within Washoe

County

be designated

as “unclassifiable”

areas

for the revised

annual

PM 25 NAAQS. If you have

any questions

or comments

regarding

this submittal,

feel
