Application Use by Special Review (Mining Operation) Use by Special Review (Mining Operation) Questionnaire Responses Page 2 f. A time table giving the periods of time and number of phases to be worked, which will be required for the various phases of the operation. There will be 2 phases of mining. NCCI I anticipates mining and reclaiming the site in approximately 10 to 15 years. Annual production is expected to be between 500,000 and 750,000 tons depending on market demands. This production rate translates to 4 to 9 years of time required to mine each phase. Reclamation will progress concurrently with the mining activity as each phase is completed. g - The depth and thickness of the mineral deposit to be mined and the thickness of overburden to be removed. The final depth of the pit will vary from 26 to 50 feet. Overburden thickness ranges from 3 to 10 feet throughout the site. The gravel deposit thickness ranges from 16 to 46 feet. See the attached soils investigation by Cesare, Inc. and boring logs by Lithos Engineering for more detailed information. h. The proposed use of reclaimed lands and an explanation of the reclamation process. The mine will be reclaimed as a lined water storage reservoir with 2 cells. The reclamation process is explained in the attached reclamation plan approved by the State of Colorado Division of Reclamation, Mining, and Safety. it The source of technical advice in that type of reclamation for open cut mining land. The sources of technical advice for this type of reclamation are the Platte Valley Soil Conservation Service and J&T Consulting, Inc, 2. A statement which explains how the proposal is consistent with the Weld County Comprehensive Plan. Section 22-5-80 of the Weld County Comprehensive Plan, paragraph A. CM.Goal 1 states "conserve lands which contain commercial mineral deposits ("aggregate") for potential future use in accordance with state law." This site contains a valuable commercial deposit of sand and gravel located in the alluvium of the South Platte River which is available for extraction. Paragraph B CM.Goal 2 states Promote the reasonable and orderly exploration and development of mineral resources. There are other mines are within one -quarter mile or less of the site. This indicates that the parcel proposed to be mined in this permit application is in a reasonable area for sand and gravel extraction activities and the orderly exploration and development of the resource can occur. 3. A statement which explains how the proposal is consistent with the intent of the district in which the use is located. This site is in the "A 1 Agricultural Zone District. Section 23-3-40 of the Weld County Code, paragraph A.3 lists "Open pit MINING and materials processing as "mineral resource development facilities" allowed by obtaining a Use by Special Review permit. The proposed use of the site as an aggregate mine is consistent with this guideline. 4. If applicable, a statement which explains what efforts have been made, in the location decision for the proposed use, to conserve productive agricultural land in the agricultural zone district, According to the "Important Farmlands of Weld County Colorado" map prepared by the USDA — Soil Conservation Service and Colorado State University Experiment Station, the site is located in the `Irrigated Land (Prime), "{Irrigated Land (Not Prime)", and "Other Land" categories of farmland. The 1111 J&T Consulting, Inc. Sill I Northern Colorado Constructors, Inc_ USA Application Use by Special Review (Mining Operation) Use by Special Review (Mining Operation) Page 3 Questionnaire Responses majority of the permit boundary is within the "Irrigated Land (Prime & Not Prime) categories as indicated on the map. 5. A statement which explains there is adequate provision for the protection of the health, safety and welfare of the Inhabitants of the neighborhood and the County. Northern Colorado Constructors, Inc. will follow The Design Standards in the Weld County Code (Section 23-2-240), and the Operation Standards (Section 23-2-250), which provide adequate provisions for the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. 6. A statement describing the existing surrounding land uses and explaining how the proposal will be compatible. The surrounding land uses include irrigated agriculture land and the South Platte River to the north, pasture land to the west, pasture land and residences to the southwest and south, and irrigated farm land and the South Platter River to the east. The site is bounded by County Road 23 on the west and County Road 2% to the south. Sand and gravel operations are located in areas similar to this along the South Platte River corridor as evidenced by other mines being in close proximity to this site. The end use for the site will be a lined water storage reservoir which is compatible with the agricultural nature of the general area. 7, A statement describing the existing land use. The existing land use is irrigated agricultural crops. two oil/gas wells and a two tank batteries are located on the site. The surface damages agreement and letter agreement with the pertinent oil/gas company are attached in draft form. The agreements are in the stage of preliminary approval. The final recorded versions of these agreements will be forwarded to the county when they are obtained. 8. Describe, in detail, the following: a. How many people (employees, visitors, buyers, etc.) will use this site? There will be a maximum of 10 employees on the site on any given day, The average number of employees per day will be 5.

Water taken from the pit dewatering once ground water is exposed will be used for dust suppression and washing if the operator chooses to wash the material. A well permit will be obtained prior to ground water being exposed. At this time the proposed operation will be washing the material during the aggregate processing. A temporary substitute water supply plan will be provided to the State Engineer for the mining operation prior to ground water being exposed. This plan will provide details of the consumptive use associated with the operation of the mine and the source of the replacement/augmentation water that will be used prior to ground water being exposed. The plan will be provided to the county when it is approved. g. What is the sewage disposal system on the property? (Existing and proposed). The proposed gravel mine install and will utilize a vault system for the scale/operator house, and on -site employees, that will be pumped prior to the vault reaching capacity. h. If storage or warehousing is proposed, what type of items will be stored? Overburden and aggregate stockpiles will be located as shown on the Extraction Plan map. The maximum height of the largest stockpiles is expected to be 30 feet. Most stockpiles will be an average of 15 to 20 feet in height. i. Explain where storage and/or stockpile of wastes will occur on this site. The waste generated by the scale/operator houses will be stored in standard storage bins located adjacent to the scale/operator houses. Explain the proposed landscaping/screening for the site, The landscaping shall be separately submitted as a landscape plan map as part of the application submittal.

The reclamation is expected to completed o n e year after the mining activities are completed. The screening berms will be constructed and the screening trees will be planted at the beginning of mining activities. I. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. The reclamation will follow the procedures outlined in the attached reclamation plan approved by the State of Colorado Division of Reclamation, Mining, and Safety. The reclamation will occur concurrently with the mining as each phase is completed with final reclamation completed approximately one year after the conclusion of mining. m. Explain how the storm water drainage will be handled on the site. The stormwater generated on the undisturbed portions of the site will follow the historic flow patterns by either infiltrating into the soil or flowing to the existing slough on the west and river to the east. The stormwater on the disturbed portions of the site will be directed to the pit and discharged to the South Platte River with the pit dewatering effluent. n. Method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. The only wastes generated by the site will be from the scale/operator houses. This waste will be collected in standard storage bins and disposed of by commercial trash haulers. o. A statement delineating the need for the proposed use. Construction aggregates are in demand along the Front Range. This site contains a significant quantity of valuable commercial grade sand and gravel which is ideally suited for meeting these needs. P. A statement which explains the Use by Special Review area is not located in a flood plain, geologic hazard and Weld County Airport overlay district area; or that the application complies with Chapter 23, Article V, Overlay District Regulations as outlined in the Weld County Code. According to the Federal Emergency Management Agency Flood Insurance Rate Map (FIRM) Community No. 080266, Map No. 08123C1915E, effective January 20, 2016, the project site lies within Zone Al which is within the 100 -year floodplain. All structures will be anchored to protect against flooding and all electrical components will be installed a minimum of 1 foot above the 100 year flood elevation. A floodplain study and Flood Hazard Development Permit has been included in the USR Application submittal materials for review and approval. According to the U.SDepartment of the Interior and U.B.

Bennett Pit Traffic Impact Study J&T Consulting, Inc. Weld County, Colorado February 12, 2018 Bennett Pit Traffic Impact Study 1.0 Introduction Northern Colorado Constructors (NCC) is proposing to develop the Bennett Pit east of Weld County Road 23 (WCR 23) adjacent to the intersection with Weld County Road 24 (WCR 24). Figure 1 shows the location of the site. The development will consist of a quarry which is expected to be operational in May 2018. The quarry is expected to operate Monday through Saturday during daylight hours with the end of the business day at 4:00 p.m. The study has been prepared based on the Weld County traffic impact study requirements1. 2.0 Project Description 2.1 Existing and Proposed Streets and Intersections The intersection of WCR 24 / WCR 23 will provide access to the development. It is a T -intersection of two lane collector roads. The intersection has side street stop control for the eastbound traffic on WCR 24. Access to the quarry will be through a new east leg to the intersection. 2.2 Study Assumptions The following assumptions were utilized for this study. • Short Term Horizon. The County's traffic impact study requirements specify that the short term horizon is five years following the completion of the development. The Bennett Pit is assumed to be operational in May 2018, so the short term horizon is Year 2023. • Long Term Horizon. The long term horizon is assumed to be Year 2035 to coincide with the traffic projections that are contained in the 2035 Transportation Plan2. • Saturation Flow Rate. The saturation flow rate was assumed to be 1,600 passenger cars / hour / lane which is typical in rural areas. • Peak Hour Factor. The peak hour factor for the existing movements was based on the count data. For new movements, the peak hour factor was assumed to be 0.85. • Truck Percentage. Weld County reported truck percentages in the January 15, 2018 comments on the development. Those percentages were used for the analysis. Refer to Section 3.0 for the volumes and truck percentages reported by Weld County. On the east leg of the intersection that will provide access to the quarry and the new movements at the intersection, the truck 1 2 Weld County Engineering and Construction Criteria. Weld County.

Weld County, Colorado February 12, 2018 percentage was assumed to be 61% based on the trip generation and vehicle type information that was provided by J&T Consulting. 3.0 Existing Traffic volumes Traffic count data for the study were collected on Thursday December 1, 2016 by All Traffic Data. The existing daily volumes are summarized in Table 1, and the existing peak hour volumes are summarized in Table 2. The traffic count data summaries are contained in Appendix A. January 15, 2018 comments on the development that were made by Weld County included traffic count and truck percentages that are different than the information collected by STS for the traffic study. The comments did not provide a date that the data were collected or state whether they were collected on an average weekday. They are as follows: • WCR 23 south of WCR 24 - 1521 vpd with 22% trucks • WCR 23 north of WCR 24 - 715 vpd with 24% trucks • WCR 34 - 1,282 vpd with 23% trucks 4.0 Crash Data STS requested the most recent three years of crash data from Weld County for the intersection of WCR 24 WCR 23. The report provided by Weld County contains a list of several incidents at or near the intersection (see Appendix B). Six of the incidents between December 25, 2014 and November 29, 2015 were crashes. They are highlighted on the report. There wasn't enough information provided by Weld County to determine the cause of the crashes. 5.0 Site Generated Traffic Volumes 5.1 Trip Generation Quarries are not land uses addressed in the ITE Trip Generation manual3. Therefore, the trip generation was determined based on information that was provided by J&T Consulting. The truck and passenger vehicle traffic for the quarry is summarized in Table 3. The daily and peak hour traffic volumes on an average weekday are expected to be 35 truck trips and 22 passenger vehicle and light duty truck trips. 5.2 Trip Distribution and Assignment The trip distribution for the truck traffic was provided by NCC and is shown in Figure 2. NCC assumes that approximately 50% of the truck traffic will occur on WCR 24, and the other 50% will be on the south leg of WCR 23. Passenger vehicle and light duty truck traffic will be associated with employees and vendors. That traffic is assumed to be divided equally between the three directions of travel from the site. The daily trip assignment is contained in Table 1 and the peak hour trip assignment is contained in Table 2. The distribution of traffic entering and exiting the site was based on count data collected at the Pikeview Quarry in Colorado Springs. 3 Trip Generation, 10th Edition. Institute of Transportation Engineers. September 2017. Sustainable Traffic Solutions, Inc. 2 Bennett Pit Traffic Impact Study J&T Consulting, Inc. Weld County, Colorado February 12, 2018 6.0 Future Traffic Volumes Background traffic volumes (without the development traffic) were estimated by using the projected volumes for each leg of the intersection and inflating the existing volumes to appropriate levels based on the projected volumes that are contained in Appendix A of the 2035 Transportation Plan. Tables 1 and 2 contain the Year 2023 and Year 2035 background traffic volumes. The projected daily and peak hour volumes at the completion of the project were estimated by adding the traffic that is expected to be generated by the Bennett Pit to the background traffic volumes (see Tables 1 and 2). 6.1 Auxiliary Lanes STS reviewed the need for auxiliary lanes at WCR 24 /WCR 23. The evaluation was based on criteria that are contained in Section 6.6 of the Weld County Engineering and Construction Criteria. Weld County has the following thresholds for the construction of auxiliary lanes on arterial and collector roadways. • Left Turn Declaration Lane. A left turn deceleration lane is required when peak hour volumes exceed 10 vehicles per hour. • Right Turn Deceleration Lane. A right turn deceleration lane is required when peak hour volumes exceed 25 vehicles per hour. • Right Turn Acceleration Lane. A right turn acceleration lane is required when peak hour volumes exceed 50 vehicles per hour. A second criterion is that the right turning traffic would be turning into a single lane. Based on the threshold for the left turn deceleration lane, a northbound left turn lane is currently warranted. 7.0 Level of Service Analysis To evaluate the performance of the intersections within the study area, the Level of Service (LOS) was calculated using PTV VISTRO software. This software package utilizes criteria described in the Highway Capacity Manual`. LOS is a measure used to describe operational conditions at an intersection. LOS categories ranging from A to F are assigned based on the predicted delay in seconds per vehicle for the intersection as a whole, as well as for individual turning movements. LOS A indicates very good operations, and LOS F indicates poor, congested operations. Acceptable intersection operation in rural areas is typically considered LOS C or better. The level of service for stop controlled intersections is based on the lowest letter grade for the side street movements. The level of service for all of the scenarios is summarized in the following table. The intersection is currently operating at LOS A and is expected to continue to operate at acceptable levels of service through the Year 2035. 4 Highway Capacity Manual, 6th Edition.

The study was performed based on requirements contained in the Manual on Uniform Traffic Control Devices5. Warrant 3, the peak hour warrant, was evaluated using the data available for this study. The intersection is not expected to warrant signalization by Year 2035. Results of the signal warrant study is contained in Appendix D. 9.0 Conclusions and Recommendations STS has drawn the following conclusions based on the analysis performed in the study. • The intersection of WCR 24 WCR 23 is expected to operate at acceptable levels of service through the Year 2035. • The peak hour traffic signal warrant was evaluated for the Year 2035 peak hours and the intersection is not expected to warrant signalization. STS has the following recommendations based on the analysis performed for this project. • Side Street Stop Control. The development will not warrant signalization of WCR 24 / WCR 23, therefore, the access will be stop controlled. • Recommended Laneage. The laneage recommendations for each volume scenario are summarized in Table 4. 5 Manual on Uniform Traffic Control Devices. Federal Highway Administration. 2009.

Bennett Pit Traffic Impact Study J&T Consulting, Inc. Weld County, Colorado March 3, 2017 Bennett Pit Traffic Impact Study 1.0 Introduction Northern Colorado Constructors (NCC) is proposing to develop the Bennett Pit east of Weld County Road 23 (WCR 23) adjacent to the intersection with Weld County Road 24 (WCR 24). Figure 1 shows the location of the site. The development will start as a quarry and may expand to include concrete and asphalt batch plants. The quarry is expected to be operational in Year 2017, and the addition of the batch plants is expected by Year 2022. The quarry and ultimately the batch plants are expected to operate Monday through Saturday during daylight hours with the end of the business day at 4:00 p.m. The study has been prepared based on the Weld County traffic impact study requirements'. 2.0 Project Description 2.1 Existing and Proposed Streets and Intersections The intersection of WCR 24 WCR 23 will provide access to the development. It is a T -intersection of two lane collector roads. The intersection has side street stop control for the eastbound traffic on WCR 24. 2.2 Study Assumptions The following assumptions were utilized for this study. • Short Term Horizon. The Bennett Pit is assumed to be operational in Year 2017, therefore, the short term horizon is Year 2017. • Long Term Horizon. The long term horizon is assumed to be Year 2022 when the quarry and batch plants will potentially be operational. • Growth in Background Traffic. Traffic on WCR 23 and WCR 24 is expected to grow based on projections that are contained in the 2035 Transportation Plan. • Saturation Flow Rate. The saturation flow rate was assumed to be 1,600 passenger cars / hour / lane which is typical in rural areas. • Peak Hour Factor. The peak hour factor for the existing movements was based on the count data. For new movements, the peak hour factor was assumed to be 0.85. • Truck Percentage. Based on the data collected for the study, the percentage of trucks was assumed to be 6%. This assumes that trucks have three or more axles. 1 2 Weld County Engineering and Construction Criteria. Weld County. April 2012. 2035 Transportation Plan. Weld County. May 9, 2011. Sustainable Traffic Solutions, Inc. 1 Bennett Pit Traffic Impact Study J&T Consulting, Inc. Weld County, Colorado March 3, 2017 6.0 3.0 Existing Traffic Volumes Traffic count data for the study were collected on Thursday December 1, 2016 by All Traffic Data. The existing daily volumes are summarized in Table 1, and the existing peak hour volumes are summarized in Table 2. Traffic count data are contained in Appendix A. 4.0 Crash Data STS requested the most recent three years of crash data from Weld County for the intersection of WCR 24 WCR 23. The report provided by Weld County contains a list of several incidents at or near the intersection (see Appendix B). Six of the incidents between December 25, 2014 and November 29, 2015 were crashes. They are highlighted on the report. There wasn't enough information provided by Weld County to determine the cause of the crashes. 5.0 Site Generated Traffic Volumes 5.1 Trip Generation Quarries and batch plants are not land uses addressed in the ITE Trip Generation manual. Therefore, the trip generation was determined based on information that was provided by J&T Consulting. The truck and passenger vehicle traffic for each of the uses is summarized in Table 3. When the quarry and the batch plants are fully operational, the daily and peak hour traffic volumes on an average weekday will include 212 truck trips and 66 passenger vehicle and light duty truck trips. 5.2 Trip Distribution and Assignment The trip distribution for the truck traffic was provided by NCC and is shown in Figure 2. NCC assumes that approximately 50% of the truck traffic will occur on WCR 24, and the other 50% will be on the south leg of WCR 23. Passenger vehicle and light duty truck traffic will be associated with employees and vendors. That traffic is assumed to be divided equally between the three directions of travel from the site. The daily trip assignment is contained in Table I and the peak hour trip assignment is contained in Table 2. The distribution of traffic entering and exiting the site was based on count data collected at the Pikeview Quarry in Colorado Springs. Future Traffic volumes Background traffic volumes (without the development traffic) were estimated by using the projected volumes for each leg of the intersection and inflating the existing volumes to appropriate levels based on the projected volumes that are contained in Appendix A of the 2035 Transportation Plan. Tables I and 2 contain the Year 2017 and Year 2022 background traffic volumes. The projected peak hour volumes at the completion of the project were estimated by adding the traffic that is expected to be generated by the Bennett Pit to the background traffic volumes (see Tables 1 and 2). 3 Trip Generation, 9t" Edition. Institute of Transportation Engineers. 2012. Sustainable Traffic Solutions, Inc. 2 Bennett Pit Traffic Impact Study J&T Consulting, Inc. Weld County, Colorado March 3, 2017 7.o 6.1 Auxiliary Lanes STS reviewed the need for auxiliary lanes at WCR 24 I WCR 23 following the opening of the quarry in Year 2017 and the batch plants in Year 2022. Weld County has criteria for auxiliary lanes that are contained in Section 6.6 of the Weld County Engineering and Construction Criteria. The following thresholds trigger the need for the construction of auxiliary lanes on arterial and collector roadways. • Left Turn Declaration Lane. A left turn deceleration lane is required when peak hour volumes exceed 10 vehicles hour. • Right Turn Deceleration Lane. A right turn deceleration lane is required when peak hour volumes exceed 25 vehicles hour. • Right Turn Acceleration Lane. A right turn acceleration lane is required when peak hour volumes exceed 50 vehicles hour. A second criterion is that the right turning traffic would be turning into a single lane. Based on the thresholds, a northbound left turn lane and an eastbound right turn lanes are currently warranted. However, the volumes at the intersection are low enough that the auxiliary lanes would not make a difference in the operation of the intersection. The County's criteria only considers the turning volume, but not the through volumes. STS reviewed the criteria in NCHRP 2794 because that criteria considers turn lane and through volumes. Figures 3 and 4 contain an evaluation of the need for a northbound left turn and right turn lanes. It can be seen that neither lane is required based on NCHRP 279 because the volumes at the intersection are very low. Level of Service Analysis To evaluate the performance of the intersections within the study area, the Level of Service (LOS) was calculated using Synchro software. This software package utilizes criteria described in the Highway Capacity Manual'. LOS is a measure used to describe operational conditions at an intersection. LOS categories ranging from A to F are assigned based on the predicted delay in seconds per vehicle for the intersection as a whole, as well as for individual turning movements. LOS A indicates very good operations, and LOS F indicates poor, congested operations. Acceptable intersection operation in rural areas is typically considered LOS C or better. The level of service for stop controlled intersections is based on the lowest letter grade for the side street movements. The level of service analysis shows that the intersection of WCR 24 WCR 23 is currently operating at LOS A. The level of service is expected to drop to LOS B in the Year 2017 and Year 2022 total traffic volume scenarios. Table 4 summarizes the operational analysis and the Synchro output is contained in Appendix C. 4 5 Intersection Channelization Design Guide. National Cooperative Highway Research Program Report 279.

Weld County, Colorado March 3, 2017 8.0 Conclusions STS has drawn the following conclusions based on the analysis performed in the study. • The intersection of WCR 241 MICR 23 is expected to operate at LOS B in the Year 2017 and Year 2022 total traffic volume scenarios. • No auxiliary lanes are required as a result of the traffic generated by the Bennett Pit.

James C. York, PE Registered Professional Engineer State of Colorado No. 36846 ii Bennett Pit: Drainage Report I. GENERAL LOCATION AND DESCRIPTION A. Introduction and Location The purpose of this report is to describe and address the drainage impacts resulting from future development associated with Bennett Pit. The site is located in the southwest quarter of Section 1 and north one-half of Section 12, Township 2 North, Range 67 West of the 6th P.M., Weld County, Colorado (see Vicinity Map in Appendix A). No streets are currently within the site. The property is currently zoned for Agriculture. The property is on the east side of Weld County Road (WCR) 23, right-of-way width is 60 feet, and north of WCR 22.5, right-of-way width is 50 feet. The site is bounded on the north by private property, the east by the South Platte River, the west by WCR 23 and private property. The South Platte River runs adjacent to the east side of the site. B. Description of Property The entire site encompasses 190.65 acres. The existing vegetation within the site consists of agricultural crops. There are no major drainage ways within the property. A slough crosses the western portion of the property. There is a defunct irrigation ditch that runs through the property that was used to irrigate the property. There are oil and gas easements on the property with producing wells. The site is generally flat with a I to 3 percent slopes. The proposed project will have a gravel pit with two cells. The total acreage for the cells is 114.8 acres +1-. The storm runoff will be directed to the bottom of the cells to be released with the pit dewatering effluent. 3 Bennett Pit: Drainage Report II. DRAINAGE BASINS AND SUB -BASINS A. Major Basin Description The historic storm water runoff generated by this site sheet flows to the north and east and exits the site along the north and east property lines. There is minimal off -site runoff from any direction on to the property. According to the current FEMA Flood Insurance Rate Map (FIRM) Community Panel No. 08123C1915E, effective date January 20, 2016, the project site lies within Special Flood Hazard Area Zone A, no base flood elevation determined. A flood elevation was determined by J & T Consulting to be between 4843.42 feet at the south end of the property to 4835.60 feet at the north end of the property. Elevations are NAVD 88 datum. The existing land use is agriculture growing row crops and oil and gas production. The proposed use within the basin is a sand and gravel mine. The Meadow Island Levee Ditch No. 1 is located west of the property. B. Sub -Basin Description The project site was divided into 6 basins for the historic analysis. See the historic drainage plan in Appendix C. The imperviousness was assumed at 2%. Basin A contains the southwest section of the property, consisting of 16.04 acres. The runoff coefficients are calculated to be 0.26 and 0.51 for the 10 and 100-yr storms, and generate a runoff of approximately 14.59 cubic feet per second and 45.65 cubic feet per second for the 10 and 100-yr storm events respectively. Basin B is located in the central -west section of the property, consisting of 1.81 acres. The runoff coefficients are calculated to be 0.17 and 0.36 for the 10 and 100-yr storms, and generate a runoff of approximately 1.05 cubic feet per second and 3.73 cubic feet per second for the 10 and 100-yr storm events respectively. 4 Bennett Pit: Drainage Report Basin C contains the west section of the property, consisting of 5.01 acres. The runoff coefficients are calculated to be 0.17 and 0.36 for the 10 and 100-yr storms, and generate a runoff of approximately 2.96 cubic feet per second and 10.46 cubic feet per second for the 10 and 100-yr storm events respectively. Basin D is located on the west side of the north of the property, consisting of 1.13 acres. The runoff coefficients are calculated to be 0.17 and 0.36 for the 10 and 100-yr storms, and generate a runoff of approximately 0.66 cubic feet per second and 2.34 cubic feet per second for the 10 and 100-yr storm events respectively. Basin E contains the east section of the property, consisting of 23.57 acres. The runoff coefficients are calculated to be 0.07 and 0.22 for the 10 and 100-yr storms, and generate a runoff of approximately 5.93 cubic feet per second and 29.94 cubic feet per second for the 10 and 100-yr storm events respectively. Basin F contains the central section of the property, consisting of 143.17 acres. The runoff coefficients are calculated to be 0.17 and 0.36 for the 10 and 100-yr storms, and generate a runoff of approximately 59.07 cubic feet per second and 208.61 cubic feet per second for the 10 and 100-yr storm events respectively. The proposed development of the site was split into seven (7) basins. See the developed drainage plan in Appendix C. The basins were selected due to the topography and design of the sand and gravel mine pits. Basin A is located in the southwest corner of the property on the west side and including the slough that runs across the property, consisting of 16.04 acres. The runoff coefficients are calculated to be 0.26 and 0.51 for the 10 and 100-yr storms, and generate a runoff of approximately 14.59 cubic feet per second and 45.65 cubic feet per second for the 10 and 100 year storm events respectively. This basin will be unchanged by the proposed use. Basin B is located in the central -west area of the property in the location of an area identified as wetland, consisting of 1.81 acres. This land will remain undeveloped. The runoff coefficients are calculated to be 0.17 and 0.36 for the 10 and 100-yr storms, and generate a runoff of approximately 1.05 cubic feet per second and 3.73 cubic feet per second for the 10 and 100 year storm events respectively. 5 Bennett Pit: Drainage Report Basin C is located in the west of the property and connects the property to WCR 23, consisting of 5.01 acres. The runoff coefficients are calculated to be 0.37 and 0.50 for the 10 and 100-yr storms, and generate a runoff of approximately 6.62 cubic feet per second and 14.40 cubic feet per second for the 10 and 100 year storm events respectively. The land generally directs the runoff east to a wetland area located in the eastern half of the basin. This wetland drains to the South Platte River. Basin D is located on the west side of the north of the property, consisting of 1.13 acres. The runoff coefficients are calculated to be 0.17 and 0.36 for the 10 and 100-yr storms, and generate a runoff of approximately 0.66 cubic feet per second and 2.34 cubic feet per second for the 10 and 100-yr storm events respectively. This basin will be unaltered. Basin E contains the east section of the property, consisting of 23.57 acres. The runoff coefficients are calculated to be 0.07 and 0.22 for the 10 and 100-yr storms, and generate a runoff of approximately 5.93 cubic feet per second and 29.94 cubic feet per second for the 10 and 100-yr storm events respectively. The basin drains directly to the South Platte River and will remain undeveloped. Basin F contains the south section of the property that will be the South Cell of the mining operation, consisting of 97.53 acres. The runoff coefficients are calculated to be 0.36 and 0.50 for the 10 and 100-yr storms, and generate a runoff of approximately 111.83 cubic feet per second and 248.72 cubic feet per second for the 10 and 100-yr storm events respectively. The basin is self-contained and will not have stormwater runoff. Basin G contains the north section of the property and will be the North Cell of the mining operation, consisting of 45.64 acres. The runoff coefficients are calculated to be 036 and 0.50 for the 10 and 100-yr storms, and generate a runoff of approximately 62.04 cubic feet per second and 137.98 cubic feet per second for the 10 and 100-yr storm events respectively. All stormwater will be contained within the basin. There are no offsite tributary areas to the site. 6 Bennett Pit: Drainage Report BENNETT PIT SUMMARY HISTORIC BASIN TABLE Basin Basin(s) Area (Acres) Peak Basin Basin Flow Q(10) (cfs) Peak Flow Q(100) (cfs) A 16.04 14.59 45.65 B 1.81 1.05 3.73 C 5.01 2.96 10A6 D 1.13 0.66 2.34 E 23.57 5.93 29.94 143.17 59.07 208.61 F DEVELOPED BENNETT SUMMARY PIT BASIN TABLE Basin Basin(s) Area (Acres) Peak Basin Basin Flow Q(10) (cfs) Peak Flow Q(100) (cfs) A 16.04 14.59 45.65 B 1.81 1.05 3.73 C 5.01 6.62 14A0 D 1.13 0.66 2.34 E 23.57 5.93 29.94 97.53 111.83 248.72 F G 45.64 62.04 137.98 7 Bennett Pit: Drainage Report III. DRAINAGE DESIGN CRITERIA A. Development Criteria Reference and Constraints There are no Master Plans for this area or previous drainage studies. The surrounding properties have no drainage plans either. The change to the drainage of this property will have no effect on the surrounding land due to the increase of stormwater runoff being contained in the pit and in the reservoir after the sand and gravel pit mining is completed. B. Hydrological Criteria A 1 -hour rainfall depth of 1.68 inches and 2.71 inches were used for the 10 and 100 year storm event, respectively. These values were taken from the City of Fort Lupton's Storm Drainage: Design and Technical Criteria. These were used instead of Weld County rainfall due to the proximity to the project site. Peak runoff was calculated using the rational method peak runoff spreadsheet provided by Urban Drainage and Flood Control District (UDFCD) and can be found in Appendix A. No detention calculations were made due to all runoff being contained in the pit or reservoir after mining is completed. C. Hydraulic Criteria There is no design for the conveyance of the stormwater on the site. All storm water from Basin A and B will be contained within the North and South cell of the sand and gravel mining operation. Basin C will drain directly to the wetland area along paths that exist currently. IV. DRAINAGE FACILITY DESIGN A. General Concept The site drainage will be changed with the creation of the two mining pits. After the area has been mined, there will be the ability to store water in the pits. The proposed surface area of the North Cell 8 Bennett Pit: Drainage Report is approximately 33 acres and the surface area for the South Cell is approximately 65 acres. Runoff from the property will run into the pits and be contained within each independently. There will be minimal infiltration laterally due to the slurry wall that will be installed surrounding the pits. The water will be able to infiltrate down. During a flood event for the South Platte River, the water will flow around and into the pits. The stormwater runoff from Basin C will continue to flow to the wetland area located in the east portion of the basin. B. Specific Details Due to the design of the site, there is no drainage system, detention pond, outlet structures, or swales. There are three (3) culverts on the property. One crosses the access road for the irrigation ditch. The second culvert is for the slough being crossed by the access the road. The third culvert is for nuisance flows for the swale along the west side of the south cell. The culverts were sized based on UDFCD calculated peak flows using the Rational Method spreadsheet and CUHP spreadsheet. See Appendix Afor calculations. The basins were evaluated from Weld County 2 foot interval GIS topography. Sizing of the culverts was done with AutoCAD Hydraflow. See Appendix B for culvert calculations. There is no adverse impact on downstream properties since the stormwater will be contained on site. No rise to the floodplain will result from the mining activities. The river during a flood state will be able to go into and out of the pit through side channel spillways that will be constructed on the east sides of both cells. See Appendix C for spillway calculations and configurations. V. CONCLUSIONS A. Compliance This report and the design of the drainage infrastructure comply with the hydrologic and hydraulic regulations for the land use per the Weld County requirements. g Bennett Pit: Drainage Report B. Drainage Concept The sand and gravel mining operation will have a slurry wall constructed surrounding the excavation. The water on the site will infiltrate into the ground or be pumped out into the South Platte River at a controlled rate. Side channel spillways will control flood flows entering and exiting the reservoir cells during flood events. The mining operation will have no adverse impact on the adjacent and downstream properties. 10 Bennett Pit: Drainage Report REFERENCES City of Fort Lupton Storm Drainage: Design and Technical Criteria, City of Fort Lupton, 2015.

Warning: Soil Map may not bevalid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (AID, BID, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, BID, or CID), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

According to Technical Review Guidelines for Gravel Mining & Water Storage Activities from Urban Drainage and Flood Control District, the equation for the side channel spillway length is: L 0.6xAp 12,000 Ls = length of the side channel spillway Ap area of pit measured in square feet at the high water line The calculated surface area for the North and South cell combined at the high water line is 4,271,494 square feet. The calculated length of the spillway is 213.6 feet which was rounded to 215 feet. The riverside berm protection was designed based on Figure 2.8: Riprap Spillway Stabilization from the Technical Review Guidelines for Gravel Mining & Water Storage Activities shown below. The pitside id e protection was designed using the Rock Chute Design Program based on "Design of Rock Chutes" by Robinson, Rice, and Kadavy, ASAE Vol. 41(3). The results sheet is included.

Wastes will be generated by the scale/operator house and be stored in a standard dumpster located adjacent to the scale/operator house. The expected volume of waste generated will be trash from the operation of the scale house and the employees of the mining operation (i.e. lunch containers, beverage containers, etc.). The volume will be collected in a one cubic yard dumpster and collected bi-weekly by the waste handler. The proposed operation will have a diesel fuel tank with secondary containment. A Spill Prevention Control and Countermeasures (SPCC) plan will also be in place for the fuel storage. The SPCC plan will be available at the site at all times. The fuel storage tank will be permitted through the State of Colorado - Department of Labor and Employment - Division of oil and Public Safety if it falls within their regulations. The tank will also be permitted with the Fort Lupton Fire Protection District if they require a permit. The waste handler and facility where waste will be disposed is as follows: Waste Handler: Waste Management Facility Name: North Weld Landfill Address: 40000 Weld County Road 25 Ault, Colorado 80610 Phone Number (866) 482-6319 If you need additional information please do not hesitate to contact myself at (303) 857-1754 or J.C.

A water truck will be used to treat the on -site areas (haul roads, aggregate processing area, etc.) in order to suppress dust. A water truck and/or sprinklers will be used to control dust in circulation areas and material handling/stockpile areas. Vehicle speeds will be reduced on -site and posted at 10 mph on the access road into the pit and 10 mph within the pit. All loaded trucks will be required to tarp/cover loads when entering or exiting the pit to aid in dust suppression. On a daily basis prior to starting up plant operations all haul roads, processing area, circulation areas, and stockpiles will be inspected to determine if wetting the surfaces are needed. If the roads and stockpiles are dry where dust could be generated they will be wetted using a water truck. Areas that cannot be reached with the water truck will be wetted using sprinklers. The same areas will be inspected again at mid -day to determine if wetting the areas is needed. If at anytime during the day the mining operations begin to generate dust that is leaving the site Northern Colorado Constructors will have the water truck on stand-by such that an area can be wetted immediately.

Based upon those discussions, Northern Colorado Constructors, Inc. C), along with our engineer have designed various disturbance mitigation solutions in response to your concerns. The list of proposed mitigation items are as follows: 1. NCC will construct a 345 -linear foot (LF) concrete mafia block wall to the south of the irrigation ditch running to the east on the southern property line, The wall will be approximately 8 ft. high and 12 ft. wide. The interior of the wall will be filled with overburden and topsoil taken from the Bennett Pit. Trees and/or shrubs, such as lilacs and blue spruce trees, will be planted atop the wall to improve the aesthetic appearance of the wall. The top of the interior of the wall will be covered with landscape fabric and 1.5 in. landscape rock, A drip irrigation system will be installed to supply water to the vegetation. 2. NCC will fill areas on the south side of the irrigation ditch with overburden and topsoil to the level of the irrigation ditch. This will provide better access for the utility companies to access their utility infrastructure. The fill area will also include the existing pond area on the eastern portion of the property that lies to the south of the irrigation ditch, 3. NCC will construct a dirt berm on the northern portion of the Bennett property running between the interior access road, east to the property line just south of the pond area. The berm will be approximately' 10 ft high with slopes built 2 ft to 1 ft. The apex of the berm will be approximately 6 — 8 ft wide. The berm will be constructed of overburden and topsoil. Trees, such as Blue Spruce and Australian Pines, will be planted along the apex of the berm. An irrigation drip system will be installed to provide water to the vegetation. 4. NCC will install a 6 ft woven wire fence along the property line between the access road and the property line south of the pond. We will tie into an existing fence on your property. These items are reflected in Exhibit A "Bennett Gravel Pit — Cantrell Property." All. the above -mentioned items (1-4) will remain in place for as long as there are any traffic in the corridor to south of Cantrell's house. By constructing the above referenced mitigation items, you agree to withdraw your objections to the mining permit being applied for with the Colorado Division of Reclamation, Mining and Safety for the Bennett Pit. If you do not withdraw the objections, this agreement becomes null and void and NCC is not obligated or liable to construct any of the above referenced items. If the Colorado Division of Reclamation, Mining and Safety does not issue a mining permit for the subject property, this agreement becomes null and void and NCC is not obligated or liable to construct any of the above referenced items.

For linear transportation pr6 ccts in tidui walrus, the discharge cannot cause the loss of greater than 1 / 3 -acre of waters of the United States. Any stream channel modification, including bank stabilization, is limited to the minimum necessary to construct or protect the linear transportation project; such modifications must be in the immediate vicinity of the project. This NWP also authorizes temporary structures, fills, and work, including the use of temporary mats, necessary to construct the linear transportation project. Appropriate measures must he taken to maintain normal downstream flows and minimize flooding to the maximum extent practicable, when temporary structures, work, and discharges, including cofferdams, are necessary for construction activities. access fills, or dewatering of construction sites. Temporary fills must consist of materials, and be placed in a manner. that will not be eroded by expected high flows. Temporary fills must be removed in their entirety and the affected areas returned to pre` construction elevations. The areas a t tected by temporary tills must be revegetated, as appropriate. This NWP cannot be used to authorize non-linear features commonly associated with transportation projects, such as vehicle maintenance or storage buildings, parking lots, train stations, or aircraft hangars. Notification: The permitic'e must submit a pre -construction notification to the district engineer prior to commencing the activity if: (1) The loss of waters o 1. i I ae United States exceeds 1/10 -acre; or (2) there is a discharge in a special aquatic site, including wetlands. (See general condition 32,) (Authorities: Sections 10 and 404) Note 1: For linear transportation projects crossing a single waterbody more than one time at separate and distant locations, or multiple waterbodies at separate and distant locations, each crossing is considered a single and complete project for purposes ofNWP authorization_ I _inear transportation projects must comply with . 33 CFR 330.6(d). Note 2: Some discharges for the construction of farm roads or forest roads, or temporary roads for moving mining equipment, may qualify for an exemption under section 404(f) of the neat Water Act (see 33 CFR 323.4). Note 3: For NWP 14 activities that require pre -construction notification. the PCN must include any other N WP(s), regional general permit(s), or individual permit(s) used or intended to be used to authorize any part ()lithe proposed project or any related activity, including other separate and distant crossings that require Department of the Army atrt.hori .�itiuit but do not require pre - construction notification (see paragraph (h) of general condition 32). The district engineer will evaluate the PCN in accordance with Section D, "District Engineer's ee:r's Decision.". Eke district engineer may require mitigation to ensure that the authorized activity results in no more than minimal individual and cumulative adverse environmental effects (see general condition 23). Nationwide Permit General Conditions Note: To qualify for N WP authorization, the prospective permittee must comply ith the following general conditions, as applicable, in addition to any regional or case-specilic conditions inlposctT by the division engineer or district engineer. Prospective permittees should contact the appropriate Corps district office to determine if regional conditions have been imposed on an Nom'.

Activiiies that result in the physical destruction (e.g., through excavation, till, or downstream smothering by substantial turbidity) of an important spawning area are not authorized, r l rateBird Breedin, Areas. Activities in waters of the United. States that serve as breeding areas for migratory birds must be avoided to the maximum extent practicable. 5. Shellfish Beds. No activity may occur in areas of concentrated shellfish populations, unless the activity is directly related to a shellfish harvesting activity authorized by ' Ps 4 and 48, or is a shell fish seeding or habitat restoration activity authorized by P 7. 6. Suitable Material. No activity may use unsuitable material (e.g„trash. debris, car bodies, asphalt, etc.). Material used for construction or discharged must be free from toxic pollutants in toxic amounts (see section 307 of the Clean Water Act). 7. Water Supply_ Intakes. No activity Ina) occur in the proximity or a public water supply intake, except where the activity is for the repair or n upri'v cment of public water supply intake structures or adjacent hank stabilization. 8. Adverse Effects from Impoundments. lithe activity creates an impoundment of w .ter, adverse effects to the aquatic system due to accelerating the passage of water, and/or restricting its flow must be minimized to the maximum u extent practicable. 9 Management of Water Flows. To the maximum extent practicable, the pre -construction course; condition, capacity, and location of open waters must he maintainedfor each activity. including stream ch u!Tn l nation, storm water management activities, and temporary and permanent road crossings, except as provided below. The activity must be constructed to withstand expected high flows. The activity must not restrict or impede the passage of normal or high flows, unless the primary purpose of the activity is to impound water or manage high flows. The activity may alter the pre- construction course. condition, capacity, and location of open waters if it benefits the aquatic environment (e.g., stream s restoration or relocation activities). 10. Fills Within in 100 -Year Floo_4pla- us.. The activity must comply with applicable F FM -approved state or local floodplain management requirements. 11. Equipment. Heavy equipment working in wetlands or mudtlats must he placed onmats, or other measures must he taken to minimize soil di i L►rbacice. 12. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction, and all exposed :soil <rid other fills, as well as any work below the ordinary high water mark or high tide tine. mast be permanently stabilized at the earliest practicable date. Permittces are encouraged to perform work within waters of the United States during periods of low-11OW or no -flow, or during low tides. 13. Removal of'i-`empora v Fills. Temporary fi l k must be removed in their entirety and the affected areas returned to pre - construction elevations. The affected areas must he revegetated, as appropriate_ 14. Proper Maintenance. Any authorized structure or fill shall he properly maintained, including maintenance to ensure public safety and compliance with applicable MVP general conditions, as well as any activity - specific conditions added by the district engineer to an NWP authorization. 1. Single and Complete Project. The activity must be a single and complete project. The same NWP cannot be used more than once for the same single and complete project. 16. Wild and Scenic Rivers. (a) No NWP activity may occur in a component of the National Wild and Scenic River System, or in .a river officially designated by Congress as a ..study river' for possible inclusion in the system while the river is in an official study status, unless the appropriate Federal agency with direct management responsibility for such river. has determined in \\ riling that the proposed activity will not adversely affect the Wild and Scenic River designation or study status (b) If . proposed NWP activity will occur in a component of the N �tioii t Wild and Scenic River System, or in a river officially designated by Congress as a •m'study riNer's for possible inclusion in the system white the river is in an official study status, the permittce must submit a pre - construction notification (see general condition 32). The district engineer will coordinate the PUN with ate Federal agency with direct management responsibility for that river. The permittee shall not begin the NWP activity until notified by the district engineer that the Federal agency with direct management responsibility for that river has deteL-► 7 mned in writing thatthe proposed N WI) activity will not adversely affect the Wild and Scenic River designation or study status. (c) In formation on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency responsible for the designated Wild and Scenic River or stud river (e.g.. National Park Service. U.S.Forest ervi e_ Bureau of Land Management, U.S..Fish and Wildlife Berenice, information on these rivers is also available at: httpiliviroomivers.govi. 1.7. Tribal Rights. No NWP activity may cause more than minimal adverse effects on tribal rights (including treaty rights), protected tribal resources, or tribal lands. 18. Endangered Species, (a) No activity is authorized under any NWP which is likely to directly or indirectly jeopardize the continued existence of a threatened or endangered species oil a species proposed for such designation, as identified under the Federal Endangered Species Act (ESA), or which will directly or indirectly destroy or adversely modify the critical habitat of such species. No activity is authorized under any NWP which "may affect" a listed species or critical habitat, unless ESA section 7 consultation addressing the effects of the proposed activity has been completed. Direct effects are the immediate effects on listed species and critical habitat caused by the NWP activity, indirect effects are those effects ects on listed species and critical habitat that are caused by the NWT activity andare later in time. but till are reasonably certain to occur. (b) Federal agencies should follow their own procedures for Corn plying with the requirements of the ESA. I in pre- construction notification is required for the proposed activity, the Federal permittee must provide the district engineer with i the appropriate documentation to demonstrate compliance with those requirements. The district engineer will verify that the appropriate documentation has been submitted. lithe appropriate documentation has not been suhmittel. additional ESA section 7 consultation may be, necessary for the activity and the respective federal agency would be responsible for fulfilling its obligation under section 7 of the ESA. (c) Non-federal permittees must submit a pre-constructioinnotification to the district engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the activity. or if the activity is located in designated critical habitat, and shall not begin work on the activity until notified h. the district engineer that the requirements of the ESA have been satisfied and that the activity is authorized. For activities that II -tight affect Federally -listed endangered or threatened species or designated critical habitat. the pre -construction notification must include the name(s) of the endangered or threatened species that might be affected by the proposed activity or that utilize the designated critical habitat that might be affected by the proposed activity. The district engineer will determine whether the proposed activity, "may affect' or will have "no effect" to listed species and designated critical habitat and will notify the non -Federal applicant of the Corps'. determination within 45 days of receipt of a complete pre -construction notification. In cases where the non- Federal applicant has identified listed species or critical habitat that might be affected or is in the vicinity of the activity, and has so notified the Corps, the applicant shall not begin work until the Corps has provided notification that the proposed activity will have "no effect; ° on listed species or critical habitat, or until ESA section 7 consultation hasbeen completed. If the non- Federal applicant has not heard back from the Corps within 45 days., the applicant must still wait for notification from the Corps. . (d) As a result of formal or informal consultation with the FWS or NMI'S the district engineer may add species- specific permit conditions to the NWPs. (e) 1rther /ation of an activity by an NWP does not authorize the ,"take" of a threatened or endangered species as defined under the ESA. In the absence of separate authorization (e.g,., an ESA Section 10 Permit, a Biological Opinion with incidental take' provisions, etc.) from the FWS or the I' S, the Endangered Species Act prohibits any person subject to the jurisdiction of the United. States to take a listed species, where "take means to harass. harm, pursue, hunt, shoot, wound, kill. trap, capture. or collect, or to attempt to engage in any such conduct. The word 'harm' in the definition of n taken meads an act Inch actually kills or injure wildlife. Such an apt may, include significant habitat modification or. degradation where it actually kills or injures wild3lte by significantly impairing essential behavioral patterns.. incLuding breeding, feeding or sheltering. (0 Ifthe non-federal permittee has a valid ESA section 10(01)(B) incidental take permit with an approved Habitat Conservation Plan for a project or a group of projects that includes the proposed N WP i ty, the non-federal applicant should provide a copy of that ESA section I 0(a)(1)03) ) permit with the PCN required by paragraph (c) of this general condition. The district engineer wilt coordinate with the aLteney that issued the ESA section 10(a)( )(B) permit to determine whether the proposed NWP activity ty and the associated incidental take were considered in the internal ESA section 7 consultation conducted for the ESA :section I O(a)(1)(B) permit. if thatcoordination results in concurrence from the agency that the proposed NWP activity and the associated. incidental take were considered in the internal ESA section 7 consultation for the ESA section 1'0(x0 I. )(B) permit, the district engineer does not need to conduct a separate ESA section 7 consultation For the proposed NWP activity. The district engineer will notify the non-federal applicant within 45 days ofreceipt of a complete pre -construction notification whether the ESA section 1 O(a0( I R ) permit covers the proposed NWP activity or whether additional ESA section 7 consultation is required. (g) information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the FM'''S and NMFS or their world wide Web pages at http://www.f-ws.gov/ or http:// ww.i s.gov/ipac and http:// www.amfs.noaa. ov/pr/specie ''e ' respectively. 19. Mi. raton Birds and. Bald and Golden Eases. phe permittee is responsible for ensuring their action complies with the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. The permittee is responsible for contacting appropriate local office of the U.S. Fish and Wildlife Service to determine applicable measures to reduce impacts to migratory birds or eagles,. including whether ``inc idtcn tat take' permits are necessary and available under the Migratory Bird Treaty Act or Bald and Golden Eagle Protection Act for a particular activity. 20. Historic Properties. (a) In cases where the district engineer determines that the activity may have the potential to culuse effects to properties listed. or eligible for listing, in the National Register of l tistoric Places, the activity is not authorized, until the requirements of Section 106 of the National Historic Preservation Act (E) have been satisfied. (b) Federal permittees should follow their own procedures for complying with the requirements of section 106 of the National Historic Preservation Act. I.14pre-construction notification is required for the proposed. NWP act i v Lyi the Federal permittee ttee must provide the district engineer with the appropriate documentation to demonstr ae compliance with those requirements. The district engineer nil! verify that the appropriate documentation has been submitted. If the appropriate documentation is not submitted, then additional consultation under section 106 may be necessary. The respective ledera.l agency is responsible for fuLtillini4 its obligation to comply with section 106. (c) Non-federal permittees must submit a pre -construction notificationto the district engineer if the N'A'T' activity might have the potential to cause effects cls to any historic properties fisted on. determined to be eligible for listing on. or potentially eligible for listing on the National Register of Historic Places, including previously unidentified properties. For such activities, the pre - construction notification must stale which historic properties might have ate potential to be altected by the proposed NWP activity or include a vicinity map indicating the location of the historic properties or the potential for the presence of historic properties. Assistance regarding information on the location of, or potential for, the presence of historic properties can be sought from the State Historic Preservation Officer, Tribal Historic Presentation Officer, or designated tribal representative, as appropriate, and the National Register of Historic Places (see 33 CFR 330.4(g)). When reviewing pre -construction. notifications, district engineers will comply with the current procedures for addressing the requirements of section 106 of the National Historic Preservation Act. The district engineer shall make a reasonable and goodfaith effort to carry out appropriate identification efforts, which may include background research. consirlt.ation, oral history interviews, sample field investigation, and field survey. Based on the n formation submitted in the PCN and these identification efforts. the distr=ict engineer shall determine whether the proposed NWP activity has the potential to cause effects on the historic properties_ Section 106 consultationis not required when the district engineer determines that Hie fie activity does not have the potential to cause effects on historic properties (see 36 CFR 00.3(a)). Section 106 consultation is required when the district engineer determines that the activity has the potential to cause effects on historic properties. The district engineer will conduct consultation with consulting parties identified under 36 CFR 800.2(c) when he or she makes any of the following effect determinations for the purposes of section 106 of the 1 -IPA no historic properties affected, , no adverse effect or adverse effect. Where the non -Federal applicant has identified historic properties on which the activity might have the potential to cause effects and so notified the Corps, the non=l 'ede ral applicant shall not begin the activity until notified by the district engineer either that the activity 1 1� � has no potential to cause effects to historic properties or that NIVA section 106 consultation has been completed. (d) For non-federal permittees, the district engineer ick,,ill notify the prospective permittee within 45 days of receipt of a complete pre -construction notification whether NLIP section 106 consultation � is required, 1 F HPA section 106 consultation is required, the district engineer will notify the non-, Federal applicant that he or she cannot begin the, activity until section 106 consultation is completed. If the non -Federal applicant has not heard back from the Corps within 45 days. the applicant must still wait for notification cation from the Corps. (e) Prospective permittees should be aware that section 110k of the NAPA (54 U.S.C. 306113) prevents the Corps from granting a permit or other assistance to an, applicant who, with intent to avoid the requirements uirements of section 106 of the NLIP , has intentionally significantly adversely affected a historic property to which the permit would relate. or having legal power to prevent it, allowed such significant adverse effect to occur, unless the Corps, after consultation with the Advisory Council on 1- [ istoric Preservation (ACHP), determines that circumstances justify granting such assistance despite the adverse elect created or permitted by the applicant.. I I circumstances justify granting the assistance, the Corps is required to notify the ACHP and provide documentation specifying the circumstances, the degree of' damage to the integrity of any historic properties affected, and proposed mitigation. This documentation must include any views obtained from the applicant, S1-iPU/ TUPO, appropriate Indian tribes if the undertaking occurs on or affects historic properties on tribal lands or affects properties of interest to those tribes.. and other parties known to have a legitimate interest in the impacts to the permitted activity on historic properties 21. Discovery of Previously Unknown Remains and Artifacts. if you discover any previously unknown historic. cultural or archeological remaines, and artifacts while accomplishing the activity authorized by this permit, you must immediately notify the district engineer of what you have found, and to the maximum extent practicable, avoid construction activities that may affect the remains and artifacts until the required coordination has been completed. The district engineer will initiate, the "e��eral, Tribal. and state coordination required to determine if the items or remains warrant a recovery etThrt or if the site is eligible for listing, in the National Register of l-listririe Places. 22. Designated Critical Resource Waters. Critical resource waters include, NOAA-managed marine sanctuaries and marine monuments , and National Estuarine Research Reserves. The district engineer may designate, after notice and opportunity for public comment, additional waters officially designated by a state as having particular environmental or ecological significance, such as outstanding national resource waft e, or state natural heritage sites. The district engineer may also designate additional critical rest ' u r.tc waters after notice and opportunity for public comment. (a) Discharges ofdredged ed or fill material into waters of the United States are not authorized by NWPs 7, 12, 14. 16, 17, 21, 29, 31, 35, 39, 40, 42, 43, 4, 49, 50, 51, and 52 for any activity within, or directly affecting, critical resource waters, including wetlands adjacent to such waters. (hl For NWPs 3, 8. 10. 134 1. 18, 19, 22, 23. 2 ,, 27, 28, 30, 33, 34, 36, 37 38. and 54, notification is required in accordance with general condition 32, foray activity proposed in the designated critical resource waters including wetlands adjacent to those waters.. The district engineer may authorize activities under these NWPs only after it is determined that the impii t to the critical resource waters will be no more than minimal.. 23. Mitigation. The district engineer will consider the following factors when determining appropriate and practicable mitigation necessary to ensure that the individual and cumulative adverse environmental effects are no more than minimal: (a) The activity must he designed and constructed to avoid and minimize adverse effects, both temporary and permanent, to waters of the United States to the maximum extent practicable atthe project site (i.et, on site). (b) Mitigation irt all its forms (avoiding, minimizing, rectifying, reducing, or compensatine for resource losses) will be required to the extent necessary to ensure that the individual and cumulative adverse enviromnental effects are no more than minimal. (c) Compensatory mitigation at a minimum one -for -one ratio will he required for all wetland losses that exceed 110 -acre and require prey construction notification, unless the district engineer determines in writing that either some() .er form of mitigation would be more environmentally appropriate or the adverse environmental effects of the proposed activity are no more tharn minimal. and provides an act i ity-specific waiver of this requirement. For wetland losses of 1/10 - acre or less that require pre- construction notification, the district engineer may determine On a case -by- cLise basis that compensatory mitigation is required to ensure that the activity results in only m nimn1 adverse environmental effects. (d ) For losses of streams or other open waters that require pre -construction notification the district engineer may require compensatory mitigation hi ensure that the activity results in no more than minimal adverse environmental effects. Compensatory mitigation for losses o f ' strews should be provided. if -practicable, through stream rehabilitation, enhancement. or preservation, since streams are difficult- to -replace resources (see 33 CUR 332.3(e)(3)). (e) Compensatory mitigation plans for NWP activities in or near streams or other open waters will normally include a requirement for the restoration or enhancement, maintenance, and legal protection (eg. conservation easements) of riparian areas next to open waters. In some cases, the restoration or maintenance/protection of riparian areas may he the only compensatory mitigation required. Restored riparian areas should consist of native species. The width of the required riparian area will address documented water quality or aquatic habitat loss concerns. Normally* the riparian area alt be 25 to 50 feet wide on each side of the stream. hut the district engineer may require slightly wider riparian areas to address documented water quality or habitat loss concerns. If it is not possible to restore or maintain/protect a riparian area on both sides of a stream, or if the waterbody is a lake or coastal waters, then restoring or maintaining/protecting a riparian area along a single hank or shoreline may be sufficient. Where both wetlands and open. waters exist on the project site, the district engineer will determine the appropriate cot peti s,Lt,,'ry mitigation (erg.. riparian areas and/or wetlands compensation) based on what is best for the aquatic environment on a watershed basis. in cases where riparian areas are determined to be the most appropriate form of minimization or compensatory mitigation, the district engineer may waive or reduce the requirement to provide wetlandcompensatory mitigation for wetland losses. (i) Compensatory mitigation projects provided to offset losses al aquatic resources must comply with die applicable provisions of 33 CFR part 332. (1) The prospective peri ittee is responsible for proposing an appropriate compensatory mitigation option if compensatory mitigation is necessary to ensure that the activity results in no more than minimal adverse environmental effects. For the NWPs, the preferred mechanism for providing compensatory mitigation is mitigation bank credits or in -lieu fee program credits (see 33 CFR 332.3(b)(2) and (3)). However, if an appropriate number and type of mitigation hank or in - lieu credits are not available at the time the PCN is submitted to the district engineer, the district engineer may approve the use of permittee-responsible mitigation. (2) The amount of compensatory mitigation required by the district engineer must be sufficient to ensure that the authorized activity results in no more than minimal individual and cumulative adl , erse environmental effects (see 33 CFR 330,1(e)(3)). (e) 3 Th. (See also 33 CFR 332.31)). (3) Since the likelihood of success is greater andthe impacts to potentially valuable uplands are reduced, aquatic resource restoration should be the first compensatory mitigation option considered for pennittee-responsible mitigation. (4)1 If pet -mince -responsible mitigation is the proposed option, the prospective permittee is responsible for submitting a mitigation plan. A conceptual or detailed mitigation plan may be used by the district engineer to make the decision on the I. P verification request, but a final mitigation plan that addresses the applicable requirements of 33 CFR 3 3 ' 4(O(2) through t 14i i.nust be approved by the district engineer before the permi ttce begins work in waters of the United States,, unless the district engineer determines that prior approval of the final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation (see 33 CFR 33213(k)(3)) (5) If mitigation bank k or in -lieu fee program credits arc LIIC proposed option, the mitigation plan only needs to address the baseline conditions at the impacts to and the number of credits to he provided. (6) Compensatory mitigation requirements (e.g, resource tie and amount to he provided as compensatory mitigation, site pmkction. ecological performance standards, monitoritie requirements) may be addressed through conditions added to the NWP authorization, instead of components of a compensatory mitigation plan((see 33 CFR 3314(c)(1)(ii))! (g) Compensator) mitigation will not be used to increase the acreage losses allowed by the acreage limits or the NWPs. For example, if an NWP has an acreage limit of -acre, it cannot he used to authorize any NWP activity resulting in the loss of greater than 1/21- acre of waters of the United States, even if compensatory mitigation is provided that replaces or restores some of the lost waters. However, compensatory nmitigation can and should be used, as necessary, to ensure that an NWP ac ti v i t already meeting the established acreage limits also satisfies the no more than minimal impact requirement for the NWPs. P s. (h) Permittees may propose the use of mitigation k nks, in -lieu fee programs, or perri it.tee- responsible mitigation. When developing a compensatory mitigation proposal, the permittee must consider appropriate and practicable options consistent with the framework at 33 CFR 3323(K. For activities resulting its. the loss of marine or estuarine resources, permittee- responsible mitigation may be environmentally preferable if there are no mitigation banks or in -lieu lee programs in the area that have marine or estuarine credits available for sale or transfer to the permittee. For perntitlee responsible mitigation, the special conditions of the NWP verification must clearly indicate the party or parties responsible for the implementation and performance i ance of the compensatory mitigation project, and, if required, red, its bong-terni management. (i; Where certain functions and services of waters of the United States are permanently adversely affected by a regulated activity, such as discharges es of dreded or till material into waters of the United ikUc that will convert a forested or scrub -shrub .ctitincd to a herbaceous wetland in a permanently maintained utility line right-of-way, mitigation may he required to reduce the adverse environmental effects of the activity to the no more than minimal level 24. Safety of Impoundment Structures. r10 ensure that all impoundment structures are safely designed, thedistrict engineer may require non -Federal applicants to demonstrate that the structures comply with established state dam safety criteria or have been designedby qualified persons. The district engineer may also require documentation that the design has been independent l v reviewed by similarly qualified persons., and appropriate modifications made to ensure safety. Water Quality. Where States and authorized Tribes, or EPA where applicable, have not previously certified compliance of an NWP with CWA section 401. individual 401 Water Quality Certification must he obtained or waived (see 3 CFR 330.4(c)). The district engineer or State or Tribe may require additional water quality management measuress to ensure that the authorized activity does not result in more than minimal degradation of water quality. 26 Coastal Zone Management In coastal states where an NWP has not previously, received a state coastal. zone management consistency concurrence, an individual state coastal zone management consistency concurrence must he obtained. or a presumption of concurrence must occur (see 33 C1 R 330.4(d)). The district engineer or a Stine may require additional measures to ensure that the authorized activity is consistent wit.1 slate coastal /one management requirements. 27..e Waal. and Case -B Case Conditions.. The activity must comply with any regional conditions that may have been added by the Division Engineer (see 33 CFR 330.4(e) and with any case specific conditions added by the Corps or by the state, Indian Tribe, or t LS. EPA in its section 401 Water Quality Certification. or by the state in its Coastal Zone Management Act consistency determination. 28. Else of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project is prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit. For example. ila road crossing over tidal waters is constructed ender NWP 14. with associated bank stabilization authorized by NWP 13, the maximum acreage loss of waters of the United States for the total project cannot exceed 1 -acre. 29. Transfer of Nationwide Permit Verifications. If the per wince sells the property associated with a nationwide permit verification, the perrn.ittee may transfer the nationwide permit verification to the new owner by submitting a letter to the appropriate Corps district office to validate the transfer. A copy of th.e nations idle permit verification must he attached to the letter, and the letter must contain the fnl kiwi nu statement and signature: when the structures or work authorized by this nationwide permit are still in existence at the time the property is transferred, the terms and conditions of this nationwide permit, including any special conditions, will continue to be binding on the new owner(s) of the property. To validate the transfer of this nationwide permit and the associated liabilities associated with compliance with its terms and conditions, have the transferee sign and date. lelww. (transferee) (Date) 30, Compliance Certification. Each permittce who receives an NWP verification letter from the Corps must provide a signed certification documenting, completion of the authorized activity kind implementation of any required compensatory mitigation. The success of any required pCIi _ ittee-responsible mitigation, including the achievement of ecological per.lbrmance standards, will be addressed separately by the district engineer. The Corps will provide the permittec the certification document with the NWP verification letter. The certification document will include: (a) A statement that the authorized activity was done in accordance with the MVP authorization, including any general, regional, or activity -specific conditions; (b) A statement that the implementation of any required compensatory mitigation was completed in accordance with the permit conditions: if credits from a mitigation bank or in -lieu :lee program are used to satisfy the compensators, mitigation requirements, the certification roust include the documentation required by 33 CFR 332.3(00) 00) to coni irrn that the pernu i tree secured the appropriate number and resource type of credits; and (c) The signature or the pc.nniuucc certifying the completion of the activity and mitigation. The completed certification document must be submitted to the district engineer within 30 days of completion of the authorized activity or the implementation of any required compensator\ mitigation, whichever occurs later. 31. Activities Affecting Structures or Works Built by the United States. If an NWP activity also requires permission from the Corps pursuant to 33 U} .C- 408 because it will alter or temporarily or permanently occupy or use a LS. Army Corps o rrn ineer-s (I IS CF.) federally .authorized Civil Works project (a"USACE projects"), the prospect i e permittee must submit a pre- construction notification. See paragraph (b)( I U) of general condition 32. An activity that requires section 408 permission is not authorized by 'P until the appropriate Corps office issues the section 408 permission to alter, occupy. or use the USAGE project, and the district engineer issues a written \ P verilication. 3. Fire -Construction Notification. (a) Timing. Where required by the terms of the W1', the prospective permittee must notify the district engineer by submitting a pre -construction notification (PCN) as early as possible. The district engineer must determine if the PCN is complete within 30 calendar days of the date of receipt and, if the PCN is determined to be incomplete, nti l -v the prospective permittee within that 30 day period to request the additional information necessary to make the PCN complete. The request must specify the information needed to make the PCN complete. As a general rule, district engineers will request additional information necessary to make the PCN complete only once. i Iowever, i l' the prospective permittee does not provide all of the requested information, then the district engineer will noti Cy the prospeeti \ e permittee that the PCN is still incomplete and the PCN review process will not commence until all oldie requested information has been reed udby the district engineer. The prospective permittee shallnot begin the activity until either: 1) Ile or she is notified in writing by the district engineer that the activity may proceed under the NWP with any special conditions imposed by the district or division, engineer; or (2) 45 calendar days have passed from the district engineer's receipt of the complete PCN r a - f �• .� a • • . • c and the prospective permittee has not received written notice from the district or division engineer. However, i 1' the permittee was required to notify the Corps pursuant to general condition 18 that listed species or critical habitat might be affected or are in the vicinity of the activity, or to notify the Corps pursuant to general condition 20 that the activity might have the potential to cause effects to historic properties. the peen ittce cannot begin the activity until receiving written notification from the Corps that there is "no effect" on listed species or ` •no potential to cause effects" on historic properties, or that any consultation required under Section 7 of the Endangered Species Act (see 33 CFR 33O.4(f) land/or section 106 of the National Historic Preservation Act (see 33 Oa 330.4(g)) has been completed. Also, work cannot begin under N NT's 21. 49, or 50 until the perrnittee has received written approval from the Corps. If the proposed activity requires a written waiver to exceed specified limits °fan NWP, the permittee may not begin the activity until the district engineer issues the waiver. If the district or division engineer notifies the permittee in writing that an individual permit is required within 45 calendar days of receipt of a complete PCN, the permittee cannot begin the activity until ail individual permit has been obtained. Subsequently, the perr ttce `s right to proceed under the N W I) may be modified. suspended, or revoked only in accordance with the procedure set torch in 33 CFR 330.50)(2). (h) Contents of PreeConstruction Notification: The PCN must be in writing and include the following information: 0) Name. address and telephone numbers of the prospective permittee: (2) Location of the proposed activity: (3) Identify the specific N W P or NWP(s) the prospective permittee wants to use to authorize the proposed activity; (4) A description of the proposed activity; the activity's purpose: direct and indirect adverse environmental effects the activity would cause, including the anticipated amountof toss of wetlands, other special aquatic sites, and other waters expected to result from the NWP activity. in acres, linear feet. or other .appropriate unit of measure a. description of any proposed mitigation measures intended to red Luce the adverse environmental effects caused by the proposed activity; and any other NWP(s), regional general permit(s), or individual permit(s) used or intended to be used to authorize any part of the proposed project or any related activity, including other separate and distant crossings for linear projects that require Department of the Army authorization but do not require pre -construction notification. The description of the proposed activity and any proposed mitigation measures should be sufficiently detailed to allow the district engineer to determine that the adverse environmental effects of the activity will be no more than minimal and. to determine the need for compensatory mitigation or other mitigation measures. For single and complete linear projects, the PCN must include the quantity of anticipated losses of wetlands, other special aquatic sites, and other waters for each single and complete crossing, of those wetlands... other special aquatic sites, and other waters. Sketches should be provided when necessary to show that the activity complies with thy° terms of the NWP. (Sketches usually clarify the lt:iivity and whenprovided results in a r Hick or decision.. Sketches should contain sufficient detail to provide an � illustrative description of the proposed activity (e.g., a conceptual plan), but do not need to be detailed engineering plans); (5) The PCN must include a delineation of wetlands, other special aquatic sites, and other waters. such as takes and ponds, and perennial, intermittent. and ephemeral streams. on the project site.

Reseeding — See Seed Mix Reccommendation from Brighton NR — Platte Valley Soil Conserviation District Field Office Rangeland -Pasture Recommendations Canada thistle Identification and Management Canada thistle (Cirsiurn arvense) is a non-native deep-rooted perennial that spreads by seeds and aggressive, creeping horizontal roots (rhizomes), Canada thistle can grow 2 to 5 feet in height, The leaves are oblong, spiny, bright green in color, and are only slightly hairy on the undersurface. Flowers occur in small clusters that form on the ends of branches. They are about 1 cm in diameter, tubular shaped, and vary from white to purple in color with a strong vanilla scent (female flowers). Canada thistle emerges from its root system from late April through May. It begins to flower in late spring to early summer with increase in day length. Canada thistle only produces about 1,000 to 1,500 seeds per plant. Typically, it reproduces vegetatively through a creeping root system, and can quickly form dense stands. Every piece of root, from 1/2 to 1 inch in length, is capable of forming new plants. The key to controlling Canada thistle is to eliminate seed production and also to reduce the plant's nutrient reserves in its root system through persistent, long-term management Canada thistle is one of the most feared noxious weeds in the U.S. as it can infest many land types, from roadsides, ditch banks, riparian zones, pastures, irrigated cropland, to the most productive dryland cropland. Forage production is severely reduced because cattle will not graze near infestations. Combining control methods for Canada thistle is imperative. The weed needs to be continually stressed, forcing it to exhaust root nutrient stores and eventually die. Of all control methods, prevention is most important. Maintain healthy pastures and rangeland and continually monitor your property for new infestations. On the backside of this sheet are Canada thistle management recommendations. If you have any questions, please contact the Weld County Public Works Dept., Weed Division at (970) 304-6496 ext. 3770. Please visit our website at www.weldweeds.org Recommended management methods: Cultural - Establishment of selected, aggressive grasses can be an effective cultural control ofCanada thistle. Contact your local CSU Extension office or Natural Resources Conservation Service office for seed mix recommendations. Good grazing management will stimulate grass growth and keep pastures healthy. Healthy pastures may be more resistant to Canada thistle invasion. Bare spots caused by overgrazing are prime habitat for weed infestations. Mechanical - Due to the extensive root system, hand -pulling this plant is not a viable option. Mowing can be effective if repeated at about one -month intervals throughout the growing season. Combining mowing with herbicides will further enhance control of this weed. Apply herbicides in spring and/or fall, and then mow during the summer months. Biological - Canada thistle is typically unpalatable to livestock. Although, cattle have been known to eat the plant when it is in the early growth stages. A gall fly, Urophora cardui, is effective on large infestations and when combined with other control methods. Insects can be obtained at no charge from the Colorado Department of Agriculture. Please call 970464-7916 or go to www.palisadeinsectray.com for more information. Herbicides - The following are recommendations for herbicides that can be applied to range and pasturelands.

A biennial is a plant that completes its lif ecycle within two years. During the first year of growth, diffuse knapweed appears as a rosette in spring or fall. During the second year in mid to late spring - the stem bolts, flowers, sets seed, and the plant dies. Once the plant dries up, it breaks off at ground level and becomes a tumbleweed allowing seeds to be dispersed over long distances. A prolific seed producer, diffuse knapweed can produce up to 18,000 seeds per plant. Therefore, the key to managing this plant is to prevent seed production. Diffuse knapweed can grow I to 3 feet tall, and is diffusely branched above ground. This gives the plant a ball -shaped appearance and tumble- weed mobility when broken off. Leaves are small, and are reduced in size near the flowering heads. Flowers are mostly white, sometimes purple, urn - shaped, and are located on each branch tip. Bracts that enclose the flowerheads are divided like teeth of a comb, and are tipped with a definite slender spine. Upon drying, the bracts become rough, rendering them injurious to the touch. You can expect to see flowers from July through August. Seed set usually occurs by mid -August. Diffuse knapweed tends to invade disturbed, overgrazed areas. It may also be found on rangeland, roadsides, riparian areas, and trails. It is a tough competitor on dry sites and rapidly invades and dominates disturbed areas. Once established, diffuse knapweed outcompetes and reduces the quantity of desirable native species such as perennial grasses. As a result, biodiversity and land values are reduced, and soil erosion is increased. On the backside of this sheet are diffuse knapweed management recommendations. If you have any questions, please contact the Weld County Public Works Dept., Weed Division at (970) 304-6496, ext. 3770. Please visit our website \k=Vk°%� . weldweeds.org. Recommended. management methods: Cultural -- Establishment of selected, aggressive grasses can be an effective cultural control of diffuse knapweed, Contact your local CSU Extension office or Natural Resources Conservation Service office for seed mix recommendations. Mechanical - Mowing the above -ground portion of the plant, before seed set may be an effective way to reduce seed production, Mowings should be followed by a fall herbicide treatment. Pulling can be effective on smaller infestations, but must be done repeatedly. Biological - Biological control. agents, such as the seed head weevil (Larinus minutus) s) and the gall -forming fly (uroplion-i affinis), are two of several species that are effective at controlling large i n.festations. When used together, these insects provide fair to good control. Expect to wait at least 3 to 5 years for the agents to establish significant populations and achieve optimum management results. Biocontrol agents can be obtained at no charge from the Colorado Department of Agriculture's Insectary. Please call 970464-7916 or go to www.palisadeinsectarv.com for more information. Diffuse knapweed is more likely to be grazed by sheep. The plants must be green and succulent and the only forage available in order for sheep to graze it.

Additional Diffuse Knapweed Non -Chemical Control Inforniation Diffuse knapweed response to treatments may be impacted by environmental conditions and the type of treatment utilized. Grazing control: Diffuse knapweed seed production can be reduced when grazed during the bolting stage for 10 days, wait 14 days then graze for an additional 10 days. Although grazing diffuse knapweed can reduce seed production, grazing can also cause diffuse knapweed to become a short-lived perennial. When grazing is stopped, populations often return to their former levels. Pulling or Digging: Pulling or digging requires a commitment of at least 12 years to ensure that removal of new seedlings and re -growth is done before they reestablish. Years one to three of a pulling or digging program will involve intensive removal. During year's four to six, there should be a decrease in diffuse knapweed numbers and the work will be noticeably easier. Pulling or digging of diffuse knapweed is best done in the spring during the rosette or early bud stage, before the flowers appear. Hopefully, the soils will be moist to allow for easier removal. The roots can extend a few feet into the soil. It is important to pull or dig up the entire taproot. Otherwise, the diffuse knapweed may re -grow. Keep in mind that some workers may suffer from allergic reactions while touching diffuse knapweed and inhaling pollen. Mowing: Diffuse knapweed is persistent. Mowing leaves part of the plant untouched. This part of the plant will still produce flowers. The plant will just be shorter than the mower height and will act more like a perennial plant than a biennial plant. In some cases, diffuse knapweed densities may increase after a single mowing. Burn i n. or Flaming: Normal fires are typically not long enough or hot enough to destroy diffuse knapweed seeds. A monitored controlled burn can potentially help control diffuse knapweed if the fire has adequate intensity. It is not easy to find good fuel circumstances to carry a continuous fire that will cause significant injury to the diffuse knapweed without hurting the beneficial vegetation occurring in the infestation. Diffuse knapweed is not very flammable and most areas do not contain enough fuel necessary for the fl re . This results in low temperature fires with patchy and irregular bums. Even if the surface area of the plant is killed, diffuse knapweed can often re -grow from its root reserves. A propane -fueled weed burner can be utilized to quickly burn the foliage of young diffuse knapweed rosettes. The flame sears the plant, raises the temperature of the cells, this causes the cells to rupture, The diffuse knapweed plant will then dehydrate and expire within a few hours. Flaming is done on green plants; not on dead foliage. Plants can be seared at any time before flowering. Flaming can be useful in clearing small areas. Rangeland -Pasture Recommendations Hoary Cress Identification and. Management Hoary Cress (Cardaria draba) is a non-native perennial that spreads by seeds and aggressive, creeping, roots that vigorously produce new plants. Depending on conditions, hoary cress grows to a height of 1/2 to 2 feet tall. The first leaves emerge from a crown and are dull gray -green, oblong and often have a slightly wavy margin. Subsequent leaves are alternate, have short fine hairs and an irregularly toothed margin. Only the lower leaves have stems, others are stalk -less and clasp the plant stem with two ear -like lobes. Flowers are fragrant, numerous, small, white with. 4 petals and grow in compact clusters. Hoary cress is a member of the Mustard family. In the fall seeds germinate and rosettes become established. It frequently flowers in April and May and again in the fall during optimum conditions. Seed production begins about one month. later. Hoary cress produces up to 4800 seeds per plant. Seed viability is up to 3 years. However, the primary means of spread is the vertical and horizontal root system. Root fragments are capable of forming new plants. In one year a single plant, without competition, can spread vegetatively to cover an area 12 feet in diameter and can produce 450 shoots. Hoary cress is also known as whitetop Rosette Hoary cress can be found in disturbed open sites, roadsides, ditches, riparian areas, grain and vegetable fields. It does especially well in irrigated crops such as alfalfa and sugar beets. Hoary cress grows well in most soil conditions, including alkaline soils. However, it does not tolerate shade. Hoary cress displaces native vegetation for wildlife and livestock forage. It also contains glucosinolates that are toxic to cattle. Prevention is the most cost reducing and time effective weed management strategy. Infrequent cultivation can actually facilitate the spread by dispersing root fragments. Consistent monitoring of your fields is an essential first step. On the backside of this sheet are hoary cress management recommendations.

Healthy pastures may be more resistant to hoary cress invasion. Bare spots caused by overgrazing are prime habitat for weed infestations. Mechanical - Due to the extensive root system, hand -pulling this plant is not a viable option. Repeated tillage (every 10 to 14 days) can destroy colonies in 2 to 4 years. Combining mowing with herbicides will further enhance control of this weed. Apply herbicides in spring and/or fall, and then mow during the summer months.

Rangeland -Pasture Recommendations Leafy spurge Identification and Management Leafy spurge (EuphorbIa esula) is a non-native deep-rooted perennial that spreads by seeds and extensive, creeping roots. The roots can extend as deep as 30 feet into the soil and are extremely wide -spreading. The roots are brown and contain numerous pink. buds that generally produce new shoots or roots. Leafy spurge can grow from 1 to 3 feet in height The stems are smooth, pale green, and thickly clustered. Leaves are alternate, narrow, linear, and 1 to 4 inches long. The flowers are very small and yellowish -green. They are enclosed by very visible yellowish -green, heart -shaped bracts. The entire plant contains white, milky sap that exudes readily upon stem or leaf breakage. This sap can be damaging to eyes and sensitive skin. Leafy spurge is one of the earliest plants to emerge in the spring. Flower clusters develop 1 to 2 weeks after stem emergence which is from mid -April to late May. One large leafy spurge plant can produce up 130,000 seeds. Three - sided seed capsules explode when ripe and project the seeds up to 15 feet away from the parent plant. Leafy spurge has adapted to a wide variety of habitats in the state and is very competitive with other plant species. Where it becomes established in rangeland, pasture, and ripariart sites, it crowds out all other vegetation. The competitive, rapidly growing, and extensive root system makes leafy spurge very difficult to manage. Develop a management plan that uses several control methods that are compatible with your site. The most effective method of control for leafy spurge is to prevent its establishment through proper land management. Maintain healthy pastures and rangeland and continually monitor your property for new infestations. New infestations are much more easily controlled than established infestations. On the backside of this sheet are leafy spurge management recommendations. If you have any questions, please contact the Weld County Public Works Dept., Weed Division at (970) 304-6496 ext. 3770. Please visit our website w w w .eve ld eeds.erg. Recommended many ement methods Cultural - Seeding and maintaining aggressive grasses will help in competing with leafy spurge and slow its spread. Contact your local CST.' Extension office or Natural Resources Conservation Service office for seed mix recommendations. Proper grazing management will stimulate grass growthand keep pastures healthy. Healthy pastures may be more resistant to leafy spurge invasion. Bare spots caused by overgrazing are prime habitat for weed infestations. Mechanical - Due to the extensive root system, hand -pulling this plant is not a viable option. Mowing will reduce seed production if repeated every 2 to 4 weeks during the growing season, but will provide little long-term control. Biological. - Both sheep and goats have been found to be effective grazers of leafy spurge. Grazing sheep can commence after spring regrowth reaches 2 to 6 inches tall, but before the flowering bract stage. Goats can graze spurge at any time. Do not overgraze. If leafy spurge has set seed, quarantine animals in a corral for 7 days before releasing them into a non -infested pasture. There are a variety of insects available for release on leafy spurge infestations. The flea beetles, Apthona ni, riscutis, A. lacertosa, and A, cyparissiae, have been found to be effective on large 'infestations and when used in combination with grazing and/or herbicides.

Rangeland -Pasture recommendations Musk thistle Identification and Management Musk thistle ('arduous futans) is a non-native biennial forb that reproduces solely by seed. A biennial is a plant that completes its lifecycle within two years. During the first year of growth, musk thistle appears as a rosette in spring or fall. During the second year in mid to late spring - the stem bolts, flowers, sets seed, and the plant dies. A prolific seed producer, musk thistle can produce up to 20,000 seeds per plant. 'Therefore, the key to managing this plant is to prevent seed production. Musk thistle can grow up to 6 feet tall. The leaves are spiny, waxy, and dark green in color with a light green midrib. The flowers are purple, large in size (1,5 to inches in diameter), nodding, and terminal. The flowers are surrounded by numerous, lance -shaped, spine -tipped bracts. You can expect to see flowers from late May and June, Seed set usually occurs in June or July. I i f tith iivhite in drib a .pint; edges Musk thistle tends to invade disturbed, overgrazed areas. Once a pasture is infested, the livestock carrying capacity for that area is significantly decreased. Musk thistle may also occur on rangeland, roadsides, ditches, riparian areas, and trails. On the backside of this sheet are musk thistle management recommendations. If you have any questions or would like more information, please contact the Weld County Public Works Dept., Weed Division at (970) 304-6496 ext. 3770. Please visit our website www.weldweeds.org Recommended management methods: Cultural - Establishment of selected, aggressive grasses can be an effective cultural control of musk thistle. Contact your local CSU Extension office or Natural Resources Conservation Service office for seed mix recommendations. Mechanical Mowing or chopping is most effective when musk thistle plants are at bud stage. Grubbing or digging the plants below the root crown level is effective as well. Do this while the plant is in the rosette stage. Biological - Livestock tend to avoid grazing on musk thistle, although horses and cattle have been known to eat the flowerheads. Biological control insects, such as the seed head weevil (Rhinocyilus conicus) and the crown weevil (Trichosirocalus horridus) are effective on large infestations. When used together, these insects provide fair to good control. Expect to wait at least 3 to 5 years for the insects to establish significant populations and achieve optimum management results. Insects can be obtained at no charge from the Colorado Department of Agriculture. Please call 970-464-7916 or go to ivy w w,palisadei sectorev .corn for more information.

Rangeland -Pasture Recommendations Perennial Pepperweed Identification and Management Perennial pepperweed (Lepidiurn la ti folio ni) is a non-native perennial plant that spreads by seeds and creeping underground roots that vigorously produce new plants. Seed production is prolific in heavily infested areas, estimated at 6 billion seeds per acre. The first basal leaves emerge to form a rosette. The leaves have long stems, are gray -green and can be 4 to 11 inches long and. 1 to 3 inches wide. The rosettes produce plants of multiple, erect, semi -woody stems with smaller leaves that taper toward the base and have a prominent whitish mid -vein. The leaves become progressively smaller toward the top of the stems. Flowers are white with 4 spoon -shaped petals borne in dense clusters near the stem tips. Perennial pepperweed is a member of the Mustard family. Although an enormous amount of seed is produced, most new plants are shoots from the underground root mass. The roots enlarge at the soil line forming woody crowns. Each crown produces numerous erect stems that grow 2 to 4 feet tall; feet can be achieved under optimal conditions. Root fragments as small as inches can produce a new plant. Perennial pepperweed roots can remain dormant in the soil for several years. Flowering occurs from early summer to fall. The combination of seed production and root shoots enables perennial pepperweed to develop into dense monocultures that clis lace native slants and wildlife. A field of perennial pepperweed. Perennial pepperweed can be found in riparian areas and wetlands, adapts to disturbed areas, roadsides and ditches, hay meadows and cropland. Perennial pepperweed is often confused with hoary cress. Hoary cress stems are less than 3 feet tall and have stern leaves with lobed ears that clasp the stem. Perennial pepperweed has smaller leaves that taper toward the base and have a prominent whitish mid -vein. Management programs must include prevention, monitoring, and treatment of small satellite populations before plants develop extensive roots. Focus on containment of large infestations to prevent spread. If you have any questions, please contact the Weld County Public Works Dept, Weed Division at (970) 304-6496 ext. 3770.

Therefore, the key to managing n this plant is to prevent seed production. Scotch thistle can grow up to 12 feet tall. Stems are numerous, branched, and have broad, spiny wings. The leaves are large, green, spiny, and covered with fine dense hair giving the leaf a woolly appearance. The flowers are violet to reddish in color, numerous (70-100/plant), and are surrounded by spine - tipped bracts. You can expect to see flowers from mid -June to September. Due to the robust, spiny nature of Scotch thistle, this plant can act as a living barbed wire fence, making areas impassible for wildlife, livestock, and people. Scotch thistle invades rangeland, overgrazed pastures, roadsides, and irrigation ditches. It also prefers moist areas adjacent to creeks and rivers.

The sooner it is planted, the better though, so don't necessarily wait until July ft unless you have to. This sorghum cover will help to stabilize your topsoil while you wait to seed in the fall. We would also recommend planting the grass mix after November 1st using a native grass drill. The native grass drill will be able to evenly plant the fluffier native seeds that a normal grass drill will not be able to plant as easily. Plant the grasses directly into the standing dead litter of your sorghum. The sorghum will frost kill, so there should be no need to spray it to kill it. Mix 2: Temporary cover— * Recommended species and when to plant them: By July 1st Oats By July 15th Forage sorghum, Sudangrass, Millet From August 15th to September 15th Winter wheat, Winter rye, Triticale With the first two, just seed them sooner rather than later, if possible. The last ones, plant between those dates. These are all annual grass species so they won't live year round or continue to grow back unless you let them seed out or buy sterile varieties.
