### -'03/08/02 03,09 PM cc: Subject: PMIO SIP Committment Language and Letter I have several items so far that I think need to be added to Rick's list which he's put in the letter (attached below).

• I think on the "State authorities" item they should add that all director's discretion provisions will be removed from the SIP • On the "Wood burning reduction analysis" they should add that they will justify the 83% credit taken in the Utah County SIP revision and also justify this for coal burning in addition to wood. • 24·hour emission limits will be provided for the major stationary sources in Salt Lake County • The SIP narrative will be revised and updated for such sections as the "Provo Canyon Closure to Truck Traffic," Diesel 11M, and the "Maintenance" section. • The SIP will be written to require the use of method 202 for measuring back·half condensibles from stationary sources. That's all I can think of at the moment· I'm sure there's more though. Let me know if you have anything. Thanks, Cindy

The following is a copy of my email from last week and is still what we would propose go into the SIP. The letter listing the key issues to be resolved is attached. Please take a look and let us know what you think. Thanks, Rick We would suggest inserting this at some appropriate spot in the SIP revision submittal we are sending to you. "With this revision to the PMIO SIP, the Utah Air Quality Board commits todeveloping a PM10 maintenance plan or SIP revision, as appropriate, based on dispersion modeling." I would also send a letter to Dick Long indicating our intent to resolve a number of matters listed in the letter as part of the future plan. I will finish that draft today with the list of issues to be resolved

### Richard Long Director Air and Radiation Program EPAR8 Denver, CO DearMr. Long: This letteris intended to document ouragreementto address a number ofissuespertainingto the Utah PMlO SIPs for SaltLake and UtahCounties during our ongoing effort to submit a maintenanceplan(or SIP revisions) for both counties based ona UAM-Aero attainment demonstration. We are fully committedto work with Region VIII to find solutions to these concerns, but we and our seniormanagement havejointlyrecognized thatthere may some aspects to someissues that we are unable to settle. We also understand where agreement can'tbe found that the EPA and State maythen need to seek otherremedies available in the CleanAirActif deemednecessary. Nonetheless, itremains ourobjective to resolve all issues respectful ofeach other's needs and statutoryresponsibilities. The following issues havebeenidentified and described ina series ofletters and discussions betweenEPA and the State. This letterdoes not attempt to completelydefine everyaspect of each issue sincethese are generally documented in existing correspondence. Theissues consist of: State authorities Interpollutant trading NSR offsetprogram includingemissionsbanking Unavoidable breakdownrule Woodburningreduction analysis
We look forward to completingthe new maintenance plans for PMl0 as soon as possible and are optimisticthatthe above questions canbe addressed to ourmutual satisfaction. Sincerely,

Rick Sprott Director
