Chief steckel.andrew@epa.gov Re:

Rule

1.1 and

2.31 drafts

dated 3-15-2013 We

are providing comments

based

on our preliminary

review

of the 3-15-2013

draft

rules identified

above.

We have

noted that several

of our previous comments

on these

rules

have

been incorporated

and appreciate

your efforts.

Unless otherwise

indicated,

paragraph

numbers

refer

to the draft

rule referenced

above.

Please

direct

any questions

about

our comments

to me

at (415) 947-4115

or

to Adrianne

Borgia

at (415) 972-3576. Rule

1.1: Section

202 Consider

using

the definition

of "Air Contaminanf

in SCAQMD's

rule

102 which

is

a broader definition

that includes

similar substances

but states

that

the term

is not limited

to those substances. Section

211 Consider

using

the definition

of "Combustion

Contaminant"

in SCAQMD's

rule

102 which

uses

the term "particulate

matter"

(which

is defined

in this

rule)

in lieu

of "air contaminant". Section

219.17

While

we

do

not believe

this would

be

a basis

for EPA disapproval,

we recommend

that T-butyl

acetate be exempt

except

for record keeping consistent

with

40 CFR 51.100. Section

219.19

Please

remove

the compound, Trans1-chloro-3,3,3-trifluoroprop-1-ene

(Solsticen.11233zd(E))

from

this list

of exemptions.

Because

of

an adverse comment,

EPA withdrew

the direct

final action

that would

have exempted

this compound. Section

219.24.i

Please

correct

the spelling

of Ethylfluoride
