Dear Ms. Morales:

The U.S. Environmental Protection Agency (EPA) has noted a potential deficiency in an area

source rule that should be addressed prior to the EPA's action on part of Utah's Moderate PMz.s

state implementation plan (SIP). The Utah Division of Air Quality (UDAQ) agrees that this area

source rule, R307-302, Solid Fuel Burning Devices in Box Elder, Cache, Davis, Salt Lake,

Tooele, Utah, and Weber Counties, should be revised and commits to submit a SIP revision with

the revised provision. Below is the area source rule with the original language and with the

language UDAQ is committing to submit, upon final adoption by the Utah Air Quality Board, in a

revision.

R307-302-5. Opacity for Heating Appliances currently reads:

"R307-302-5. Opacity for Heating Appliances.

Except during no-burn periods as required by R307-302-3 and 4, visible emissions from

solid fuel burning devices and fireplaces shall be limited to a shade or density no darker

than20o/o opacity as measured by EPA Method 9, except for the following:

(1) An initial fifteen minutestart-up period, and

(2) A period of fifteen minutes in any three-hour period in which emissions

may exceed the 20o/o opacity limitation for refueling."
