of Natural Resources and Environmental

Control 89 Kings Highway Dover,

DE 19901 Dear Secretary

Hughes: On June

12, 2007,

the State

of Delaware

submitted

a proposed

State Implementation

Plan (SIP) revision

entitled “Delaware

State implementation

Plan

for Attainment

of the 8-Hour

Ozone National

Ambient

Air Quality Standard Reasonable

Further Progress

and Attainment”.

This

SIP revision submittal

contained

proposed

motor vehicle emissions

budgets (MVEBs)

for 2008

and 2009.

On March

21, 2008,

we posted

the availability

of these budgets

for

the Delaware

Portion of the Philadelphia-Wilmington-Atlantic

City 8-Hour

Ozone Nonattainment

Area

on EPA’s conformity

website

for

the purpose

of soliciting

public comment.

The comment

period

closed

on April

21, 2008.

We received

no comments

on

the proposed

MVEBs. We have reviewed

the MVEBs

in the proposed

SIP revision

in accordance

with

the procedures

and criteria

for review

in the following

sections

of the Conformity

Rule:

40 CFR

Part 93, Sections

93.11 8(e)(4)(i)

through (e)(4)(vi)

and Section

93.1 18(e)(5).

This

letter transmits our decision

that

the 2008 MVEBs contained

in the

SIP revision

are adequate

for transportation conformity

purposes.

EPA’s adequacy determination

does

not address

the MVEBs contained

in the 2009 attainment demonstration. The 2008 MVEBs

are consistent

with

the required

rate

of progress

plan

for

the Delaware Portion

of the Philadelphia-Wilmington-Atlantic

City 8-Hour

Ozone Nonattainment

area.

These MVEBs

serve

to strengthen

the

SIP through continued

progress

towards attainment

and ensure that motor vehicle emissions

remain consistent

with

the emissions

levels provided

for

in the

SIP. A copy

of this letter

will

soon

be posted

on

the Internet

at http ://www. 

# epa. gov/otac/stateresources/transcon

f/adeguacy.htm.

We

will

also announce

the adequacy

finding

in the Federal Register.

The finding

will become

effective

15 days

after

the Federal Regisieier announcement. The Technical

Support Document

(TSD) entitled, “Adequacy

Findings

for

the Motor Vehicle Emissions

Budgets

in the 2008 Reasonable

Further Progress

Plan

for

the Delaware Portion

of the Philadelphia-Wilmington-Atlantic

City 8-Hour

Ozone Nonattainment

is

an enclosure
