Attached please find the draft Traffic Study we prepared for the project. This matches the deadline we discussed and we look forward to the meeting and staff report for the 1-17-12 PC meeting. We have one more person from Noble Operations that needs to chime in on traffic dispersion but he is out of the office. We may not have his comments until Monday. If it warrants changing something we will immediately contact you and resubmit accordingly early next week. In the meantime, this study gives you what you requested of us for the USR application and PC hearing needs. I can have Fred stamp the Study early to midpart of next week once we have the final input from Noble Operations. Certainly—call if you have any questions. Have a great weekend.

This pond will be used to store water for Noble's drilling and fracing operations. Once the pond is filled, large semi water trucks will be used to transport this water to their frac sites. The site is presently farmland. The pond will be constructed to accept and store piped water. It will take several weeks to fill the 30 AC-FT pond. It is anticipated that the pond will be refilled 8 times per year. Each time the pond is filled it can supply enough water to frac 2 horizontal wells. There will be 6 filling sites to load the water into the trucks for delivery once the pond is • full. These trucks will haul water for 4-8 days until the pond is depleted. Generated Trips The maximum number of trucks is based upon the fill rate and is estimated at 16.5, thus the maximum number of trips will be 33 in the peak period. The site will allow 6 trucks to be filled at one time. When the trucks are delivering water this delivery rate could go on for 24 hours, but most likely will occur only during daylight hours. Thus the peak period will be every hour in which they are operating. The water hauling will occur for 4-8 days until the pond is depleted. It will then cease for a few weeks until the pond is again filled. Once the pond is full, the hauling operations will begin again. The site will not be staffed, so only occasionally will there be someone on site. Therefore no trips are being assigned for staff or employees. Water may also be delivered to well sites that are not being fractured, but the haul rate will be considerably less than the maximum rate for fracing operations. Only the peak hour trucks will be considered in this traffic study as they represent the maximum number of trips that will occur at the site. They will not occur every day throughout the year, but will occur sporadically for several days at a time during the year.

While trucks may occasionally go south (only for a need for a local delivery), the majority will go north on WCR 57 to CSH 392. Because the hauling operation can support two fracing operations, at CSH 392 it is estimated that half of the trucks will go toward the east and half will go towards the west.

The • generated trips at other times will be considerably less than the peak hour trips used in this study. Pagel 3 Noble Energy Carpio Water Depot • January 2012 Traffic Impacts The greatest number of trips will occur when the water hauling operation is operating at its maximum capacity. The majority (estimated in the range of 99%) of the time these trips will go to the north toward CSH 392. At CSH 392, these trips will be divided with half going toward the east and half going toward the west. WCR 57 is a low volume gravel roadway. The 17 trips entering the site and 16 trips exiting the site will not cause an impact at the water loading site. At the intersection of WCR 57 and CSH 392, there will be a maximum of 16 northbound trucks during a peak hour. These trucks can be accommodated with a single lane approach. There will be 9 left turning and 8 right turning trucks on CSH returning to the water loading site. CSH 392 is classified as a category R-A (Regional Highway). This category would require a left turn deceleration lane if the number of left turns are greater than 10. A right turn deceleration lane would be required if the number of right turns are greater than 25. The projected volumes at the intersection fall below the requirements for deceleration lanes.

The submitted study does not meet the requirements of the Traffic Impact Study checklist and is incomplete; additional information is required before Public Works can make any recommendation regarding this Use by Special Review project. The staff comments below may not be all-inclusive, as other issues may arise following re-submittal of an adequate traffic study. COMMENTS: 1. The applicant was provided a copy of the County's Traffic Impact Study checklist along • with the Public Works referral dated December 13, 2011. The Traffic study submitted by the applicant is incomplete and does not include information requested in the checklist and required for all traffic studies. 2. Preliminary documentation by the applicant proposed 800 water haul truck trips (400 roundtrips) per day on Weld County Road 57, a local gravel road with less than 200 vehicles per day. However this important total proposed traffic information was omitted from the submitted study. The Traffic Impact Study needs to include the proposed truck volumes that will impact the currently unpaved WCR 57. 800 water haul truck trips per day is one of the most significant impacts of this project and must be described and mitigation proposed. The Traffic Study needs to include the total truck traffic volumes and specify that paving and maintenance will be provided. 3. The applicant has proposed two accesses to WCR 57, an entrance and an exit. These are not mentioned in the submitted report. The Traffic Study should discuss these and a sight distance analysis of these accesses should be included in the Traffic Impact Study. 4. In subsequent discussion with Baseline Engineering, the potential for trucks to exit the site and travel southbound on WCR 57 was proposed. Mitigation for impacts to the unpaved WCR 57 would be needed. Discussion of this option was not included in the January 2012 Traffic Study, clarification is requested. 5. CDOT has been provided a copy of the January 2012 Traffic Study; they will provide comment and their requirements regarding the need for acceleration/deceleration lanes on the State Highway. Any revisions to the Traffic Study would be subject to CDOT review and additional comments. 6. The proposed water depot must be assumed to be a permanent use with truck traffic and other activities at the proposed maximums. The characterizations in the submitted • report describe potential limited activities, possible reduced hours, and other potential operating conditions, however, these were not formal proposals.

Our official position is that we request a revision to the traffic study addressing the following two areas of concern, which are: 1. The applicant failed to adjust the trip generation and intersection distribution numbers based upon the size of the water trucks per the Colorado Access Code. This is from section 2.2 (4) (e) "(e) Unless specifically noted, all criteria in the Code are based on automobile operations and performance.To allow for the impact of larger trucks, buses and recreational vehicles, "passenger car equivalents" shall be determined. A passenger car equivalent of 3 for each bus and all trucks and combinations of 40 feet in length or longer, or a passenger car equivalent of 2 for each vehicle or a. combination at or over 20 feet in length but less than 40 feet shall be used for these purposes." 2. The intersection turning movements do not factor in the existing traffic already turning onto the highway at this intersection.The access code does not focus squarely on developer driven trip generation but rather the total traffic distribution at the intersection once the proposed development is in place. Given, the county road in • question is a lightly traveled gravel roadway with minimal traffic. However, some of these turn lane traffic figures are right up against the threshold for requiring a turn lane so it becomes paramount to count every piece of data. Once the numbers are adjusted to satisfy the two criteria above, it is extremely likely that this project will at least a left turn deceleration lane requirement on Highway 392. This development should warrant a left turn deceleration lane on Highway 392 entirely on the basis of their own traffic generation, before the existing background traffic is even calculated. CDOT strongly encourages the county to require the developer to construct this left turn deceleration lane immediately as part of their developer agreement. Finally, once the numbers are adjusted a right turn deceleration lane on Hwy 392 would also be in the realm of possibility.That will be a decision/recommendation based on the revised traffic study. I can be reached at 970-350-2163 if you have any questions. Thank you.

Thanks for helping. I am broaching this info with Noble as well at this same time to get them cued up for the expectation. Not sure if you remember at the very beginning of this—Noble suggested paving the road and the Weld County PW staff said that would be overkill. This kinda feels awkward now that we are back at this at the last minute......aside from the turn lane needs.

This pond will be used to store water for Noble's drilling and fracing operations. Once the pond is filled, large semi water trucks will be used to transport this water to their frac sites. The site is presently farmland. The pond will be constructed to accept and store piped water. It will take several weeks to fill the 30 AC-FT pond. It is anticipated that the pond will be refilled 8 times per year. Each time the pond is filled it can supply enough water to frac 2 horizontal wells. There will be 6 filling sites to load the water into the trucks for delivery once the pond is full. These trucks will haul water for 4-8 days until the pond is depleted and then no truck traffic • will be seen during weeks when the pond is being filled. Site Information • Description of Use o "I'he current use of the parcel is agriculturally based. The proposed use is for a water storage depot that includes a 30 acre foot capacity pond, a six bay water filling station, and two access points from County Road 57 into the site(entry and exit). The permit for access points to CR 57 is included with the USR application and anticipated to be approved by the Public Works staff. This facility is planned to be a permanent facility. • Hours of Operation o The site is planned to be used 24 hours a day and seven days a week when hauling is needed. At times, scheduling of water delivery may not necessitate night-time hour hauling. It is expected that both AM& PM peak hours will see traffic from the site on everyday that hauling occurs. • Number of Employees o There will not be any employees stationed permanently at the site. The site will be accessed by water trucks and maintenance personnel on an as needed basis.

The street is gravel with one lane in each direction. o CSH 392 is a State Highway approximately 1 mile north of the site. CSH 392 is classified as RA-Regional Highway with a speed limit of 65 mph. There is one lane each direction at WCR 57with no turning lanes 0 Pagel 3 Noble Energy Cava Water Depot • January 2012 • Existing Traffic Data o County staff has indicated that WCR 57 presently has less than 200 vehicles per day. o The CDOT web site shows that traffic on CSII 392 is between 1000 and 1800 vehicles per day. o Due to the low traffic volumes,the streets will be operating with no delay and thus no LOS analysis was done as it would be meaningless. Future Conditions • Trip Generation o The maximum number of trucks is based upon the fill rate and is estimated at 16.5,thus the maximum number of trips will be 33 in the peak period. The site will allow 6 trucks to be filled at one time. When the trucks are delivering water this delivery rate could go on for 24 hours,but most likely will occur only during daylight hours. Thus the peak period will be every hour in which they are operating. In a straight 24 hour period,400 trucks could be filled based on the 6 fill-stations and the amount of time it takes to fill a tank on trucks. The maximum haul trips per day will be 800 on WCR 57. Existing traffic volume for trips on • WCR 57 is less than 200. Thus the maximum daily trips on WRC 57 when the water hauling is in operation will be less than 1000. '['he water hauling will occur for 4-8 days until the pond is depleted. The number of days of hauling is dependent on the number of hours trucks haul in a day. It will then cease for a few weeks until the pond is again filled. Once the pond is full,the hauling operations will begin again. The site will not be staffed, so only occasionally will there be someone on site. Therefore, no trips are being assigned for staff or employees. Water may also be delivered to well sites that are not being fractured, but the haul rate will be considerably less than the maximum rate for fracing operations. Only the peak hour trucks will be considered in this traffic study as they represent the maximum number of hourly trips that will occur at the site. They will not occur every day throughout the year, but will occur sporadically for several days at a time during the year. • Trip Distribution o The pond is intended to supply the operations of Noble Energy Inc. in the immediate Wattenberg Field area. The proposed haul route has all trucks leaving the site going to and returning from CSH392. Because the hauling operation can support two fracing operations, at CSH 392 it is estimated that half of the trucks • PageI4 Noble Energy Carpio Water Depot • January 2012 will go toward the east and half will go towards the west. The following figure shows the trips generated by the site and the distribution of those trips. The figure shows the generated Peak I lour Trips (33 truck trips) when the water hauling operation is in effect. lagnu Wai.,ileVRw ra,t iv N A ' WGR(IL • • Pe,k Hour lop Honerat on rstorialos • Short Term (5 Years) and Long Term Background Traffic and Peak Hours (10-20 Years) o Due to the extremely low existing traffic volumes at the site future traffic was not estimated. • Level of Service Analysis o A Level of Service is calculated based upon average delay to vehicles. With the low volumes involved on WCR 57 no delay is anticipated, thus an LOS analysis was not performed. • Level of Service Deficiencies o No deficiencies are expected. • Signal Warrant Analysis o Neither the site access, WCR 57, the intersection of WCR 57, and CSH 392 will meet any signal warrant. • Auxiliary Turn Lane Warrant Analysis o Due to the low volumes proposed on WCR 57, no auxiliary turn lanes are needed. • Pagel 5 Noble Energy Cain Water Depot January 2012 o The generated truck traffic at the intersection of CSH 392 and WCR 57 is converted to equivalent passenger vehicles by multiplying by 3 (as per section 2.2(4)(e)of the State Access Code). This means that there will be 27 additional westbound left turns on CSH 392 turning into WCR 57 and 24 additional eastbound right turns on CSH 392 turning into WCR 57. CDOT requires turning lanes when the left turn volumes exceed 10 vph and right turn volumes exceed 25 vph. • Sight Distance Analysis o The pictures attached to the Access Application show that there is unlimited sight distance in both directions available at the new site access points onto WCR 57. • Other Impacts o No other impacts arc anticipated. Mitigation • Describe Auxiliary Lanes Lengths and Storage Capacity o The CDOT standard calls for the right deceleration lane. The standard calls for 800' of deceleration length including the taper for the right turn lane. The standard calls for 800' of deceleration length and 75' of storage fora total of 875' • for the left turn lane. Every effort will be made to install these turn lanes according to the CDOT standards within the existing ROW. Once the design is started, if sufficient ROW is not available,discussions will be held with CDOT on how to best proceed. • Corrections for LOS Deficiencies o No LOS deficiencies are anticipated. • Correction for any Access Deficiencies o No deficiencies are anticipated at the new access. The access will have two driveways, an entrance and an exit. The accesses will be designed with large radii to accommodate the trucks as requested by county staff. There will be sufficient room on site to store any waiting trucks so the no truck storage will occur on WCR 57. Photos attached to the access application show that there is unlimited sight distance at the access points. • Signing and Striping o Signage will be installed to designate the one way operation of the entrance and exit site accesses. • Pavement Maintenance o The County staff has requested that WCR 57 be paved from the Site to CSI1 392. The applicant feels that paving 1.25 miles of an existing gravel road may be too much for a roadway that will only he used approximately 8 times per year for 4-8 • Pagel 6 Noble Energy Carpio Water Depot January 2012 days. The applicant would propose that they be allowed to perform any maintenance required and place dust suppressant on the roadway before each hauling session. • Intersection Radii for Truck Turn Improvements o Large 65' radii are being proposed at the accesses as requested by the County. Figures and Tables • Existing Peak hour Turn Movements Volumes o WCR has less than 200 vpd and CSH 392 has between 1000 and 1800 vpd. No figure or table is included. • Trip Distribution (%) including added project peak hour traffic volumes o As the above figure shows, 100%of the project traffic will go to and come from the north. • Comprehensive Plan future Year Turn Movement Volumes o Future turning movements are not included. • Intersection Performance Existing Conditions o Due to the low traffic volumes involved, no figures are included. • Project 'Trip Generation o There will be 33 truck trips during the peak hours, 16 northbound trips and 17 southbound trips from CSH 392. The above figure shows these truck trips and assumes one truck still filling on site during the peak hour. Once these trips reach CSH 392 they are increased by a factor of 3. According to Colorado Access Code Section 2.2(4)(e) trucks that exceed 40 feet are to be counted as 3 car equivalents. Therefore,the following chart is provided to summarize traffic counts according to the State Access Code and the code equivalent counts for large truck traffic envisioned. Northbound Trips from Equivalent of 48 Car Site to CSH 392 16 Truck Trips Trips Southbound"Trips From Equivalent of 51 Car CSH 392 to the Site 17 'Truck"Trips Trips Totals: 33 Truck Trips 99 Car Trips • Intersection Level of Service o No delay is anticipated so no LOS figures or tables are provided. S Pagel 7 Noble Energy • Carpio Water Depot January 2012 Conclusion of Traffic Impacts The greatest number of trips will occur when the water hauling operation is operating at its maximum capacity. All of these trips will go to the north toward CSH 392. At CSH 392, the trips will be divided with approximately half going toward the east and half going toward the west. WCR 57 is a low volume gravel roadway. The 17 truck trips per hour entering and 16 exiting the site will not cause an impact at the water loading site. At the intersection of WCR 57 and CSH 392, there will be a maximum of 16 northbound trucks, 8 turning right and 8 turning left, during a peak hour. These trucks can be accommodated with a single lane approach. The plan envisions 9 left turning and 8 right turning trucks on CSH 392 returning to the water loading site via CR 57. This translates to an addition of 27 left turning and 24 right turning passenger equivalents. CSH 392 is classified as a category R-A (Regional Highway). This category requires a left turn deceleration lane if the number of left turns are greater than 10 car equivalents and a right turn deceleration lane is required if there are greater than 25 passenger car equivalents. A left turn deceleration lane is required since the number of left turns is greater than 10 car equivalents. A right turn deceleration lane is required since the number of right turns is greater than 25 car equivalents. • Every attempt will he made to construct these two turning lanes on CSH 392. There is a concern that there is not enough right-of-way available for the additional lanes. If that is the case when design is started, CDOT will be contacted about how best to proceed. The number of vehicles on WCR 57 could increase to almost 1000 vehicles per day during the days that the water hauling is in operation. That volume will exist for 4-8 days approximately 8 times per year. The rest of the time during the year there will be no additional traffic to the Water Depot. While the County staff has asked that the 1.25 mile stretch of road from the site to CSH 392 be paved, the applicant believes a better solution would be for the applicant to perform maintenance on the roadway and place a dust suppressant just prior to each hauling session. The applicant is willing to enter into a maintenance agreement specifying this maintenance. In summary the impacts of the water hauling operation at the Carpio Water Depot are being mitigated by the maintenance of WCR 57, the construction of an appropriate access with large radii to accommodate the trucks and the construction of the right and left turn deceleration lanes on CSH 392.

I have attached many of the memos described in the timeline. August 4, 2011- Pre-application for the project, please see the attached meeting minutes pgs 1-2. During the pre- application meeting the applicant suggested that there would be truck traffic at the facility. A Traffic Narrative was requested by Public Works at this time because the applicant stated that the amount and distribution of truck traffic was unknown. October 25, 2011-The 7 -Day Completeness Review by Public Works was prepared by Don Carroll, please see the attached memo pg 3. That memo states that the traffic narrative had not been supplied for review. The Public Works memo states that the application did not contain sufficient information for review and requested the traffic information. December 13, 2011- In response to the 7-Day Completeness memo from the County, the applicant provided a traffic estimate. Upon review of the estimated truck traffic (400 round trips per day), a full Traffic Study was requested due to the significant amount of truck traffic in a December referral memo to the Planning Department. The applicant was Opplied a copy of the County's Traffic Impact Study Checklist at this time. Please see pages 4-6 for the memo and checklist. The referral memo identifies Weld County Road as unpaved,that memo also states the WCR 57 haul route would need to be paved. Planning provided the referral memo to the applicant's engineer, the option of a continuance to allow the applicant time to perform the traffic study was discussed with the applicant's engineer. January 6, 2012 -The applicants engineer submitted a 3 page Traffic Study for the Noble-Carpio project; upon review, this was found to be incomplete, lacking significant details and so was reviewed as a Traffic Narrative. This narrative was also forwarded to Colorado department of Transportation (COOT) for their comment. January 10, 2012 —Public Works issued a memo identifying the January 6, 2012 traffic narrative as incomplete, please see pages 7-8. CDOT's initial review stated concerns regarding turn lane safety improvements on State Highway 392. CDOT also requested that the traffic narrative be revised to address multiple areas of concern. January 10-17, 2012 - Numerous phone conversations with the applicant's engineering consultant were held. These conversations were concerning the impact of the truck traffic including the requirement of paving due to heavy truck traffic, State Highway improvements, and general traffic distribution. January 13, 2012 -a wet-stamped hard copy of the revised Traffic Study was submitted. A copy was provided to COOT. January 17, 2012—Planning Commission hearing. The application was continued by the Planning Commission to allow the applicant and Weld County staff to resolve issues concerning the proposed traffic at the project facility. After the project was continued Weld County staff met with the applicant and their consultant to discuss the heavy truck traffic and potential mitigation requirements. At the time of these meetings, a formal response on the revised Traffic Study •ad not been received from CDOT. COOT provided an e-mail response after the meetings stating that the applicant has agreed to install left and right deceleration lanes on State Highway 392. COOT would need to review construction plans and a COOT access permit will need to be issued prior to construction. 1 That brings us up to date.

From: cmoore@nobleenergyinc.com [mailto:cmoore@nobleenergyinc.com] Sent: Monday, January 23, 2012 7:00 AM To: Kim Ogle; Janet Carter •c: KKnox@nobleenergyinc.com ubject: Re: Noble site on Hwy 392/ CR 57 Janet and Kim - Thank you for taking the time to meet with me and the consultants from Baseline Engineering following the continuance of our USR Application 11-0026 at the Weld County Planning Commission on Tuesday, Jan 17. As we discussed at that meeting, we are pulling together downsized numbers of truck trips into and out of the facility in an attempt to get beneath the threshold that is triggering the requirement of paving WCR 57 as a condition of approval of this application. We hope to arrive at numbers that will maintain some level of functionality of the water depot and be well below the maximum or peak rate that has been provided previously (800 truck trips with 400 loaded and 400 empty). We are looking at a reduction of the peak rate by 90% to a level number to 40 truck trips per day (20 loaded and 20 empty). I will have more clarity from our Operations group about the that level of reduction later this week and ahead of our meeting next week. In discussions with Noble senior management following the continued hearing I was not able to clearly explain the sequence of events that began with the Pre Application Meeting that I believe occurred in August through the request for a traffic study in December and the resulting paving condition that ultimately led to the Planning Commission continuance in January pending resolution of the traffic study. I apologize as I may not have all of the steps and understandings in order here but the gap between the Pre Application Meeting in August and traffic study request in December is remarkable to the extent that considerable time, effort and cost was incurred including a large expenditure relative to upsizing the NWCWD pipeline while we we're conditioning the application without the paving requirement. If I understood our discussions on the 17th centered around the number and weight of the trucks and our action items to jointly consider downsizing truck trips going forward this creates certain curiosity from my management over why the message of the paving requirement could not have been delivered at or soon after the Pre Application Meeting. I ask that you please equence me from the Pre Application Meeting into the December request for the traffic study and out into the staff quirement of paving so I can provide clarity to my management. Thank you again for the opportunity to discuss this application on Tuesday. I look forward to any further information 2 sharing that will path us forward in this application and I look forward to our meeting on the 31st.

The major change to the study is the reduction of the number of trucks that will be used during the water hauling operations. Noble Energy will restrict the number of trucks to 25/day initially. They may increase the number of trucks in the future with prior agreement from Weld County. Trip Generation The initial water hauling operation will be restricted to a maximum of 25 trucks per day or 50 trips (25 trips in and 25 trips out). Assuming a 12-hour haul day means that there will be approximately 2 trucks per hour going NB and 2 trucks per hour going 5B. The number of trips may increase incrementally in the future with a phased development. A Public Improvements Agreement with the County will govern the increase in the number of • trips incrementally with a phased approach to improve CR 57. Trip Distribution The haul route remains unchanged will all trucks going north toward CSH 392 and also returning from that direction. In special situations where water must be hauled to a site directly to the south some trips may go south on WCR 57. This would be a special situation and at the present time this is not anticipated. The Public Improvements Agreement will specify dust control requirements during instances this may occur. Mitigation Noble Energy still plans to build the turn lanes on CSH 392 as requested by CDOT. Once design is started, if sufficient ROW is not available, discussions will be held with CDOT on how to best proceed. Prior to starting the hauling operation WCR 57 will be treated as agreed to In the Public Improvements Agreement. It is anticipated that the base course will be treated and additional gravel will be applied. The roadway will be maintained during hauling operations as specified by the Public Improvements Agreement. It is anticipated that the road will be treated for dust control and the surface graded as necessary to maintain a satisfactory road condition. • Corporate Headquarters High Plains Rocky Mountains Downtown Golden Downtown Greeley Ski Village 70012th Street,Suite 220 710 11Th Avenue,Suite 105 1815 Central Park Drive,#370 Golden,Colorado 80401 Greeley,Colorado 80631 Steamboat Springs,Colorado 80487 Ph 303.940.9966 Ph 970.353.7600 Ph 970.879.1825 Fax 303.940.9959 Fax 970.353.7601 Fax 866.242.9106 Pagel 2 Carpio Water Depot Traffic Addendum February 2012 • Before the number of trucks can be increased, additional improvements to the roadway may be necessary as outlined in the Public Improvements Agreement. Conclusion of Traffic Impacts Noble Energy has agreed to mitigate the traffic impacts by limiting the number of trucks to 25/day initially (50 trips). They will also improve the roadway by treating the base and adding additional gravel as agreed to in a Public Improvement Agreement. Noble Energy agrees that regular maintenance will be preformed on WCR 57 to treat dust and to repair the surface as needed and as agreed to in the Public Improvements Agreement. Before additional trips are added, the roadway will be improved as agreed to in the Public Improvements Agreement. The turn lanes on CSH 392 will be constructed as requested by CDOT. If ROW becomes a problem when design is started, CDOT will be contacted to determine the best solution. With the roadway treatments, the maintenance of the roadway, the limit on the number of trucks and the construction of the turn lanes on CSH 392, this project will mitigate the impacts caused by the development. • Prepared by: wi g —lift - Frederick C.
