Dear Sir:
This letter constitutes a commitment by the Nevada Department of Agriculture to implement the following contingency plan contained in the Clark County Carbon Monoxide Redesignation Request and Maintenance Plan, September2008. 

### Section 175A(d) of the Clean Air Act requires that revisions to State Implementation Plans (SIP) for maintenance plans must contain contingency provisionsto assure that any violation of National Ambient Air Quality (NAAQ) Standards will be promptly corrected. In compliance with that requirement, the contingency measure proposed for this SIP revision is as follows: Upon approval of an increase to the wintertime Reid Vapor Pressure (RVP) maximum for gasoline as described in CarbonMonoxide RedesignationRequestandMaintenance Plan, September 2008, and in the event of a carbon monoxide violation of NAAQ Standards,the Bureau of Petroleum Technology of the Nevada Department of Agriculture will request that the Nevada Board of Agriculturerevert to the previous wintertime RVP maximum for gasoline.


### If a violation ofthe carbonmonoxide NAAQ Standards occurs, Clark County Department of Air Quality and Environmental Management will notify the Bureau of Petroleum Technology of the Nevada Department of Agriculture. As describedin Nevada Revised Statute Chapter 233B,because a change to the Nevada AdministrativeCode (NAC) will be necessary, the Bureau will submit a draft file (amending NAC 

### 590.065 to reflect the previous RVP maximum) to the Nevada Legislative Counsel Bureau (LCB). PetroleumTechnology will then seek approval from the Nevada Board of Agriculture to take action.

The Board of Agriculturemeets quarterly (normally

### in March,June, September and December), so this request will be made at the first Board Meeting following notification, notwithstanding deadlines for submittingagenda items for the Board Meeting.
