Your attachmentwas stripped out by our security system. However, Ithink I know whatyou want based on the email text. Attached are two spreadsheets. One withthe defaultfuels forthe three years (2017, '20, and '27). And the otherwith the higher RVP fuels. Higher in this case means 9.0 psi with aone psi waiverto 10.0 psi. thus, the E10 fuels were modeled up to 10 psi and the ElS'swere modeled to 9.0 psi. these are the fuels that match PADD 1 region (most ofthe rural counties in TN?). I ran the fuel wizard on the defaultfuels and created the high rVP ones. Nonroad should use the same gasoline fuels as onroad with one exception. No E15 fuels for nonroad. When doing you NONROAD set the E10 fuels to 100 marketshare in the nonroad fuel supply. This might be a big change for nonroad and you will have to do some manual work. Nonroad does not use the new 'fuelregion' concept but uses the old countyiD and the old NMIM fuels. I hope this is whatyou need. Thanks, -ed

As we are trying to complete thistask by Friday August 14, 2014, I ask that this chore be expedited as quickly as possible. Ifyou have any questions, please contact me. Thanks in Advance,

### Subject: RE: RVP Question Dear Amanetta Somerville, Thank you foryourquestion tothe MOVES inbox. Unfortunately, Ican onlygive you a partial response. Iwill have to ask aboutthe 1 psi waiver. Also, Unfortunately,the as -released version ofthe MOVES2014 model contains a serious bug in the FueiWizard calculations. Thus, the version thatyou have will notcompute the correctfuel changes. Do not use it.
2However, I ran yourfuel through a corrected version ofthe fuelwizard and changed the RVPs from 8.8 to 9.0 and the E15 from 7.8 to 9.0. the results are below. Our MOVES2014a version will have a correctedversion ofthe fuelwizard included. Sorry aboutthe confusion. Sincererly, The mobile inbox team
