August

3, 2012 As you may

be aware,

the Philadelphia

area

also continues

to attain

and maintain

the 1997 PMz 5 NAAQS,

based

on data

from

the 2009-2011

monitoring

period,

as per

our May

1, 2012, certification. Therefore,

approval

of the RACT/RACM

analysis

in the April 12,2010,

SIP submittal

is no longer necessary

as the requirement

for

the RACT /RACM

analysis

was suspended,

pursuant

to 40 CFR

5 1.1004(c),

by EPA’s

May

16, 2012,

clean

data determination.

To

this

end,

I am withdrawing

the portion

of the April

12, 2010,

SIP revision submittal

that pertains

to the RACT/RACM

analysis. Specifically,

the Department

is withdrawing

Section

IV.B

in

its entirety,

pages

29-31

(in part)

and Appendix

0

in

its entirety. In addition,

I am requesting

that EPA approve expeditiously

the remaining

portions

of the Aprii 12,2010,

SIP submittal

including

the attainment demonstration,

associated

MVEBs

for transportation

conformity,

and contingency

measures. Thank

you

in advance

for expediting

approval

of the transportation

conformity

MVEBs

for

the Pennsylvania

portion

of the Philadelphia nonattainment

area. Should

you have

any questions

or need additional information,

please contact

Joyce

E. Epps, Director,

Bureau

of Air Quality,
