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, September 2008. Section 175A(d) of the Clean Air Act requires that revisions to State Implementation 

Plans (SIP) for maintenance plans must contain contingency provisions to 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 Carbon Monoxide Redesignation Request and Maintenance 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 Agriculture revert to the 

previous wintertime RVP maximum for gasoline. 

If a violation of the carbon monoxide 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 described in Nevada Revised Statute Chapter 233B, because a change to 

the Nevada Administrative Code (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). 

Petroleum Technology will then seek approval from the Nevada Board of Agriculture to take action. 

The Board of Agriculture meets quarterly (normally in March, June, September and December), so this 

request will be made at the first Board Meeting following notification, notwithstanding deadlines for 

submitting agenda items for the Board Meeting.

As described in Nevada Revised Statute Chapter 233B, a workshop and hearing will be scheduled and 

held, to provide for public comment and discussion, following approval of the request by the Board of 

Agriculture. 

The comments will be presented to the Board at their next meeting for approval, and the final draft file 

sent back to LCB for processing, and placement on the agenda of the next meeting of the Legislative 

Commission. 

If there are any additional questions or comments, I can be reached at (775) 688-1 166 x231, or at
