December 11, 2012 Mr. Kim Ogle, Planner III Weld County Department of Planning Services 1555 North 17th Avenue Greeley, CO 80631 RE: USR12-0075 Plains Tampa Loading Facility Expected Traffic and Pipelines Dear Mr. Ogle: On behalf of Plains All American Pipeline, L.P. and Plains Marketing, L.P. (Plains) we provide this letter to Weld County in regards to our submitted Use by Special Review permit application for a rail loading facility near Keenesburg referred to as the Plains Tampa Loading Facility (USR12-0075). Recently, contractual obligations have been completed between Plains and two independent area producers. These two companies plan to bring pipelines to our proposed facility that will deliver crude oil produced in the area. Plains has been working to secure the pipeline delivery to the proposed facility for some time. In light of these two contractual agreements, we will be able to significantly reduce surface truck transport of crude oil from the Wattenberg Field to our proposed loading facility. Recently we submitted with our application a revised traffic study with proposed truck traffic counts of a maximum of 200 trucks per day delivering crude to the site. We hereby amend our application, reducing the proposed number of trucks to a maximum of 50 trucks per day. Given that this facility will be pipeline connected to central gathering systems it is anticipated that the truck traffic would not be significant at any time during the operation of the facility however new production or unforeseen construction delays could cause a short term need for truck access. We request that this application be processed in as timely a fashion as possible as all of the companies involved face a significant need to construct the facility and the pipelines in order to reduce traffic on roads within Weld County.

The BNSF RR runs along the west side of the site. The property is presently agricultural. The site is approximately 356 acres. The proposed development is a crude oil rail facility that serves as a transfer point for oil produced locally onto tanker rail cars for distribution to the market. Oil arrives at the site via tanker truck or pipeline where it is held in tanks until it is transferred to rail cars. BNSF will deliver a unit train to the facility consisting of 104 empty crude oil tank cars. The facility is designed to accommodate two unit trains simultaneously. To access the site a private rail road crossing will be constructed. Discussions have been held with BNSF concerning this crossing. BNSF is in agreement with the crossing. It is expected that the private crossing will have crossing lights and gates. The access point will have 100' of stacking distance between WCR 398 and the RR right-of-way to store vehicles on the access and not force the vehicles to wait on WCR 398 for a passing train. • Hours of operation The facility will operate 24 hours a day. • Number of Employees The facility will have a total of 60 employees. There will be 20 employees working 12 hour shifts, thus there will be 40 employees on site at one time during shift change. • Potential haul routes The site is accessed from WCR 398 and traffic can come from Roggen on the northeast or Keenesburg on the southwest. While an occasional vehicle may come from the northeast, the majority of the traffic to the site will come from Keenesburg, the shortest route to 1-76. At 1-76 the majority of the oil trucks will come and go from the southwest, some will go northeast on 1-76 and some will continue north on Market St and proceed north to the oil field area. The distribution percentages are shown on the Distribution Percentages figure included below. WCR 398 is paved in Keenesburg, but is gravel from Keenesburg to the site. Plains AAP Tampa Loading Facility Traffic Impact Study November 2012 BASELINE 1 Engineering • Planning * Surveying • Vicinity Map Plains AAP Tampa Loading Facility Traffic Impact Study November 2012 MBASELINE 2 Engineering • Planning • Surveying • Site Plan Plains AAP Tampa Loading Facility Traffic Impact Study November 2012 VBASELINE Engineering • Planning • Surveying Existing Site Conditions • Roadway network The site is adjacent to WCR 398, which is a local gravel road northeast of Keenesburg. Traffic will access WCR 398 from Exit 39, Keenesburg on 1-76. Some traffic could come from Exit 48 on 1-76, Roggen, but the majority of traffic will come from Keenesburg. This study will assign 100% of the traffic to the southwest, the most likely direction of traffic accessing the site. Thus this study will present a worst -case condition. • Analysis of Period Daily traffic volumes are included as part of this report. The AM and PM peak hours will be analyzed in this Traffic Study. • Existing Traffic Data The Weld County Transportation Plan recorded 137 vehicles per day on WCR 398 in 2009. The CDOT web site shows 3000 vehicles per day on Market St s/o 1-76. Peak hour volumes on Market St were obtained from 2010 CDOT counts. These peak hour counts were adjusted to 2012 volumes based upon the growth factor shown on the CDOT web site. The CDOT 20 year growth factor was used to determine 2035 volumes on Market St. AM and PM peak hours on WCR 398 are estimated at 10 vehicles/hour. The Weld County Transportation Plan projects the 2035 volume to be 190 vehicles per day. 2035 AM and PM peak hour traffic is estimated at 13 vehicles/hour. Future Conditions and Impacts • Trip Generation The trips generated by the site are estimated using the number of employees, visitors and oil truck deliveries expected at the site. ITE does not include a land use such as this in its Trip Generation manual. The estimate of Trips is based upon 40 employees per day, 200 oil delivery trucks per day and 20 miscellaneous trips to the site per day. The employee peak hour trips are estimated based upon the assumption that there are 2 shifts of employees and that the shift change will occur during the AM and PM peak hours. This will represent the worst -case condition for the number of employee trips. The oil delivery trucks will operate 24 hours a day, but most (^'80%) will occur during the daylight hours. Twelve trucks are estimated in the AM and PM peak hours or 24 round trips. This equates to 72 passenger car equivalents (pce's) in the peak hours and 1200 pce's on a daily basis. Plains AAP Tampa Loading Facility Traffic Impact Study November 2012 BASELINE 4 Engineering • Planning * Surveying It is also assumed that most of the miscellaneous trips do not occur during the peak hours. The following table shows the expected number of trips at the site on a daily and peak hour basis.

The distribution is show on the Distribution Figure shown below. • Existing Traffic, Existing + Generated Traffic, 2035 Background Traffic, and 2035 Total Traffic The following drawings show the existing peak hour traffic, the total peak hour traffic with the projected generated traffic, the projected 2035 peak hour background traffic and the 2035 total traffic. As more oil is brought to the site by pipeline in the future, the amount of oil truck traffic is expected to decrease. This study continues to use 200 trucks in 2035 and thus shows the worst case condition. Plains AAP Tampa Loading Facility Traffic Impact Study November 2012 VBASELINE Engineering • Planning * Surveying • Level of Service (LOS) The LOS of the future intersection is projected at LOS A in 2035 for both AM & PM peak hours. All approaches will be at LOS A with the existing laneage on WCR 398 and a one lane access for the Plains AAP Tampa Loading Facility. It is assumed that the site access will have a stop sign. A copy of the LOS analysis as calculated by the computer program Synchro is attached. • Signal Warrant Analysis Traffic volumes will not warrant a traffic signal at the access. • Auxiliary Turn Lane Warrant Analysis Because of the extremely low traffic volumes on WCR 398, a northeastbound right turn deceleration lane is not recommended. The large radii at the intersection will enable the trucks to easily make the turn onto the site access roadway. With the majority of traffic coming from and going to the southwest, there is no need for a southwestbound left turn lane on WCR 398. • Sight Distance Analysis There are no restrictions to sight distance at the proposed intersection. The area is relatively flat and visibility is unlimited. • Other Impacts No other impacts are anticipated with this development. Mitigation • Auxiliary Lanes No auxiliary lanes are being proposed for the development at the site access. • Corrections for LOS deficiencies LOS at the site access is projected at LOS A, thus no corrections are necessary. • Correction for any access deficiencies The access is a new access and is being designed to Weld County Specifications with large radii (65') for the trucks. • Signing & Striping A stop sign will be installed on the access roadway. Appropriate RR signing will also be installed once the private RR crossing has been designed and approved by BNSF. Since WCR is gravel, no striping is proposed. • Pavement Maintenance Plains AAP Tampa Loading Facility Traffic Impact Study November 2012 VBASELINE 6 Engineering • Planning * Surveying No maintenance is proposed to WCR 398. • Intersection Radii for truck turn movements Large radii (65') are proposed at the intersection of the access and WCR 398 to accommodate the truck traffic.
