Applicant: L.G. Everist, Inc. (LGE)
Summary: The applicant is applying for additional uses at the Can Gravel Resource, AmUSR-840. The
proposed use would be in addition to the approved mining and reclamation plans that are already
permitted. This application is not making any changes to the mining/reclamation operation. The
proposed use we are applying for is a transload/storage yard within the site. The transload
projects would all take place within an approximately 300-acre transload area, and would be
temporary- 6 months or less. See the Weld County Site Specific Development Plan and Use by
Special Review Questionnaire for more details on the proposed use.
Copies of the Carr AmUSR-840 plat maps are attached for reference. The USR and plats were approved in 2001.
The proposed additional use is a rail transload yard within the Carr AmUSR-840. Parts of the USR property
would be leased to various companies to be used as a transload yard for off-loading, temporary storage, and
load-out of their industrial materials. Each lease area would be at least 40 acres. The current rail spur within the
USR may be extended to form a complete loop to allow for more efficient transloading.
Attached are two maps titled Carr Transload Area showing the details of the transload/leasehold area.

• USR#: Am-USR-840
Site Name: Carr Gravel Resource
Applicant: L.G. Everist, Inc. (LGE)
Summary: The applicant is applying for additional uses at the Carr Gravel Resource, AmUSR-840. The
proposed use would be in addition to the approved mining and reclamation plans that are already
permitted. This application is not making any changes to the mining/reclamation operation. The
proposed use we are applying for is a transload/storage yard within the site. The transload
projects would all take place within an approximately 300-acre transload area, and would be
temporary-6 months or less. See the Weld County Site Specific Development Plan and Use by
Special Review Questionnaire for more details on the proposed use.
The following questions are to be answered and submitted as part of the USR application. If a question
does not pertain to your use, please respond with "not applicable", with an explanation as to why the
question is not applicable.
1. Explain, in detail,the proposed use of the property.
1. General Proposal
L.G. Everist, Inc. (LGE) requests additional uses at the Carr Gravel Resource,AmUSR-840. The proposed use would be
in addition to the mining operations and approved reclamation plan that are already permitted. This proposal is not
making any changes to the mining/reclamation operation.
The proposed use is a rail transload yard within the mining AmUSR-840. Parts of the USR property would be leased to
various companies to be used as a transload yard for off-loading,temporary storage, and load-out of their industrial
materials. The materials would primarily arrive via rail and exit via truck (tractor trailer). Sometimes there may be projects
which will require inbound trucks and/or outbound trains. Each transload and storage project would be of a temporary
•
nature- six(6) months or less. Each lease area would be at least 40 acres. The current rail spur within the USR may be
extended to form a complete loop to allow for more efficient transloading.
Because each transload project will be different, LGE will contact Weld County(by telephone or email) prior to new
projects with details on said project, until any time in the future when Weld County may feel this notice is unnecessary.
Notes on the current USR and permitted mining operation:
- Although LGE is not requesting any changes to the permitted mining operation, LGE would like Weld County to know
that the mining operation is significantly decreased,which has resulted in significant decreases to the number of LGE
employees and the number of trucks hauling aggregate on County roads.
- Railing materials outbound is already a permitted use. LGE has railed aggregates out of the Carr site since the site
was permitted.
- Copies of the current USR plat maps are attached for reference.
2. Materials to be transloaded
The proposed transloaded materials may include the following and other similar materials: manufactured components
related to alternative and green energy,windmill parts, large pipe and other manufactured items supporting the oil and
gas industry,wire spools, miscellaneous bulk materials (building, agricultural, non-ferrous mineral), and other non-
hazardous industrial materials.
Various heavy mobile equipment(i.e. cranes,forklifts) needed for each transload project will be transported to the Carr
site via rail or truck.
All materials would only be stored temporarily on the Carr site-there will be no manufacturing associated with the
transloaded materials while they are stored on the Carr site.
3. Leaseholders-crews and equipment
• LGE will have leases/contracts with companies who will lease an area of our permitted property for the transloading and
temporary storage of their materials. Usually the leaseholder company will provide the manpower and equipment needed
to transload and store the materials-both inbound and outbound. Sometimes there may be transload projects where
LGE employees will conduct the transload operation—unloading, storing, and loading-out the transloaded materials.
C-WELD-SiteSpec&USR-Questionnaire-2010.doc 1
WELD COUNTY SITE SPIIFIC DEVELOPMENT PLAN AND USE SPECIAL REVIEW(USR)
QUESTIONNAIRE
• The type of transload equipment and number of people in the leaseholder's transload crew will vary with the type and
amount of material being transloaded. Equipment used to transload materials from railcars to storage and then from
storage to trucks may include, but is not limited to, cranes and forklifts.
The leaseholders'transload crew size will vary depending on the quantities of, and the type/size of materials to be
transloaded. LGE can only make a rough estimate that leaseholder crew sizes will generally be 5-10 people. LGE will
contact Weld County prior to each project and give better estimates on the crew size for the specific project at that time.
The leaseholder crews and equipment will be conducting their transload activities within an active mine site, but the
leasehold areas will be separated from the mining operation. There will be no mining activities taking place in the leased
areas. As required by our company rules and by the Mining Safety Health Administration (MSHA), the outside crews will
need to check in at our office,where they will receive Site-Specific Hazard Awareness Training (this is the training that all
visitors receive).
4.Transloading operations-timing
Transloading inbound or outbound is a quick and efficient process by economic necessity. The transload crews want to
unload from rail to our site and then (months)later load onto trucks as efficiently as possible. Load-in and load-out may
take only one day, or may take a few days or weeks,depending on how the inbound/outbound shipments are scheduled.
The leaseholders transload crews are only on site for the transload operations-they do not stay on site overnight, nor for
extended periods. The crew is not needed during the time when a material is being stored-they are just needed during
transloading. A transload crew will be on site for load-in, leave,then return when it is lime to load-out the materials.
5. Storage of transloaded materials
The leased areas within the Carr AmUSR-840 will be used as temporary storage yards for transloaded materials—think of
it as storage on route between their place of manufacture and their final location and use. The material storage is
temporary-sometimes weeks, sometimes months, less than 6 months.
• There will be no need for storage buildings in relation to this proposed use. There may be temporary cargo containers
and/or trailers which will be used as storage for items related to the temporary material storage.
No additional screening from adjacent properties and public rights-of-way is needed. As mentioned above, there will be
no buildings. There is already screening in place in the form of a vegetated topsoil berm that runs about 200 feet, starting
from the rail spur and goes south,which will screen the operations from public view. Furthermore, the area designated to
be various leaseholds has already been mined, and is slightly lower than the land to the west of the permitted boundary,
the Union Pacific Rail Road (UPRR) line,and Weld County Road 21.
6. Leasehold and transloadinq area
The proposed transload leasehold area will be around 300 acres, with separate leasehold areas of at least 40 acres. The
leasehold areas where materials would be transloaded and stored on the Carr site will be along the private rail spur
located within the Carr site which comes off of the Union Pacific main line.
As long as the processing plant for the mining operation is located on the north side of the rail spur,the transload area will
stay on the south side-to keep the operations separate for safety and leasing/contract reasons. However,should the
mining operation cease or the processing plant be moved to another place in the permitted mining area,the
leasehold/transload areas could then be located on both the south and north sides of the rail spur.
A map of the Carr Transload Area is attached for reference. Please note that the leasehold areas (Parcels A-G) shown
on the map are"typical" examples of 40-acre leasehold areas. The leasehold areas will vary in location and size with
each project, but will always be at least 40 acres. Transloading (load-in and load out) will be conducted on both sides of
the rail spur, depending on the project.
Typical haul routes in and out of the lease areas are also shown on the Carr Transload Area map. The route from each
area is generally to the west of the transload area,then north out of the transload area to the north-south interior haul
route which goes to the northern entrance of the Carr USR at Weld County Road 126. The road is more than adequate in
• stability and width to handle oversize trucks associated with the transload operations. The road is graveled,fairly flat, has
berms, and has had heavy truck traffic packing it down for many years. The road is approximately 50-feet wide and has a
pull-out(tarping)area approximately 300-feet long.

WELD COUNTY SITE SaFIC DEVELOPMENT PLAN AND USE I PECIAL REVIEW(USR)
QUESTIONNAIRE
• 7. Rail spur—proposed expansion
The current private rail spur on the Carr site within the derail lock is approximately 6000 feet long. (Note:A derail lock is a
safety device that goes over railroad tracks and when the derail lock is in place, trains cannot cross in either direction.
Trains would fall off the tracks if they tried to cross the derail lock.)The 6000-foot rail spur within the derail lock is owned
and maintained by LGE. The tracks outside the derail lock are owned and maintained by Union Pacific Railroad. Future
contracts may or may not increase to a point that adding length to the rail spur would be economically viable. With this
permit proposal,we would like to permit for the allowance of constructing additional rail within the Carr site. The proposed
additional rail would add a loop to the spur that would double the length of the rail spur and connect back to the beginning
of the rail spur. With the increase in rail spur length,the area adjacent to it would be additional area to be used for easy
transloading and storage.
The current rail spur and proposed potential expansion are shown on the Carr Transload Area map.
8. Inbound and outbound transportation methods and quantities
Primarily,the materials will be brought to the site by rail and then hauled out of the site by truck (tractor trailer). LGE
expects the vast majority of inbound materials will come to the site by rail and leave by truck. However some materials
may have to come to the site by tractor trailer, and some materials may leave by rail. Having materials come into our site
by tractor trailer is not the preferred method, however,there may be times when rail access is unavailable(somewhere
along the route) and the materials would need to be brought in to the site by tractor trailer.
Primarily,the materials will leave the site by truck. Some trucks may be oversized to accommodate large materials. All
oversize trucks will be permitted as required by Weld County and/or CDOT. (see paragraph 9.)
The number of trains inbound and trucks outbound will be different for each transload project. We cannot give an
estimated number of trucks due to the fact that each project will be different. However, as mentioned above,the rail load-
in and truck load-out for each project may take only one day, or may take a few days or weeks,depending on how the
inbound/outbound shipments are scheduled. In all cases,the load-in/load-out operations for each project are temporary,
• and have very short-lived use of Weld County roads.
9. Designated haul route on Weld County roads and oversize transportation permits
L.G. Everist, Inc. (under the operator name of Andesite Rock Company) is already in a Long-Term Road Maintenance and
Improvements Agreement with Weld County, dated February 28, 2001, and with a record number 2831899, recorded
March 12, 2001. This agreement can be updated to include: the updated company name, and the preferred west-bound
haul route on WCR 126 for oversize trucks. The current agreement already noted the east-bound route as going out the
north entrance and east along WCR 126(once the road had been paved).
The recommended haul route for haul trucks associated with this proposed use is: Enter/Exit from the Carr AmUSR-840
north entrance to Weld County Road 126 and travel to/from the west to Interstate 25. An alternative route,dependent on
the size and weight of the trucks and on Weld County approval,would be to travel to the east on Weld County Road 126
to State Highway 85.
LGE understands that transportation of many of the transloaded materials by tractor trailer will require oversize permits.
The transload/leaseholder and trucking companies will be responsible for getting all the necessary oversize permits from
Weld County and CDOT. The transload and trucking companies will work with Weld County Public Works with each
project to determine the best route to take for the materials'final destination.
Please note that trucks that are used for oversize loads are specially designed to accommodate the cargo so that the
maximum weight on any one axle does not exceed state and county road weight limits.
We do not feel that a Traffic Study is warranted as this time due to the temporary and varied nature of future transload
projects (i.e. quantity of trucks, size of trucks, and length of hauling schedule)and the significant decrease in our mining
operation. We understand that a traffic study may be needed at some time in the future if there is a significant increase in
truck traffic to a point where it approaches or exceeds County thresholds.

WELD COUNTY SITE S FIC DEVELOPMENT PLAN AND USE fPECIAL REVIEW(USR)
QUESTIONNAIRE
• 10. Compatibility and non-interference with the Mining Operation
The proposed use will not interfere with our mining operation. The areas needed for transload and storage have already
been mined and will be kept separated from mining operations.
There is no change needed for drainage from what is already in place with the current USR and mining plan. The
proposed use will not require any water use,except for perhaps dust control on the leased area as needed.
There is also no change needed to the landscape plan from what is already in place with the current USR mining and
reclamation plans. When the mining is completed and whenever the transloading operations cease,the site will be
reclaimed as rangeland—as is currently approved in the USR and state permits.
Mining operations can continue on the site unimpeded by the transload operations. The remaining areas to be mined are
mostly to the south of the proposed transload use. LGE will ensure that any aggregate hauling, processing, or other
mining-related operations will not interfere with the transload operation and vice versa by specifying separate areas for the
separate activities and maintaining separate on-site mining haul routes.
2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the
Comprehensive Plan.
The proposed use of a rail transload yard (within a property which has an approved Use-by-Special-Review for Mining
Operations) is consistent with the intent of the Weld County Code, Chapter 22, Comprehensive Plan, Section 22-2-80-
Industrial Development Goals and Policies, Part C. I. Goal 3, Part D. I. Goal 4, Part E. I. Goal 5, Part F. I. Goal 6, and Part
G. I.Goal 7.
Part C. I. Goal 3. Consider how transportation infrastructure is affected by the impacts of new or expanding industrial
developments.
• Weld County Road 126 is considered the main haul route associated with the project,and is adequate in width,
classification, and structural capacity to serve the project. WCR 126 is designated as a collector status road with an 80-
foot right-of-way at full build out. Trucks associated with the proposed use being added to AmUSR-840 will use WCR 126
and head east or west to state highways. The USR plat already designated a 40-foot setback from the centerline of WCR
126 to accommodate the full build out width of the WCR 126.
Part D. I. Goal 4. All new industrial development should pay its own way.
There has already been and will continue to be cooperation between Weld County, CDOT, and the various companies
who will have temporary projects related to the proposed use as a transload yard. All oversized trucks will pay the
required oversize trucking fees assessed by Weld County-which is consistent with the requirement of this part for new
development to pay additional costs associated with the services they impact.
Part E. I. Goal 5. New industrial uses or expansion of existing industrial uses should meet existing federal, state and local
policies and legislation. (1) I. Policy 5.1. Industrial uses should be evaluated using criteria, including but not limited to the
effect the industry would have on air and water quality, natural drainage ways, soil properties and natural patterns and
suitability of the land. (2)I. Policy 5.2. Development improvements should minimize permanent visual scarring from
grading, road cuts and other site disturbances. Require stabilization and landscaping of final land forms, and that runoff be
controlled at historic levels.
The proposed use is being permitted to meet existing federal,state and local policies and legislation. The proposed use
will occur within AmUSR-840,which has been approved for mining with rail operations-a compatible use. The site
already has stormwater drainage controls and structures in place,which will be sufficient for the proposed use. The
proposed use will have little to no impact on air and water, since the use is simply unloading from rail, storage of
materials, and loading onto truck. The transload operations will be temporary projects not requiring any permanent
structures/buildings and the final end use of the property will be rangeland which is consistent with the Agricultural zoning
and the surrounding lands.

WELD COUNTY SITE sPP FIC DEVELOPMENT PLAN AND USE ilIPECIAL REVIEW(USR)
QUESTIONNAIRE
• F. I. Goal 6. Minimize the incompatibilities that occur between industrial uses and surrounding properties.
The incompatibilities that occur between the proposed industrial use as a transload yard and the surrounding properties
are minimized due to various factors. The closest distance the transload yard will be from neighboring properties is to the
west—where it will be around 2000 feet to the closest residence. The Union Pacific rail line and Weld County Road 21
are between the residence and this permitted property. Furthermore,there is an earthen berm in place along the west
side of the property which shields surrounding landowners and roads from visual and noise impacts. There will be no
buildings, since the transload operation is for temporary storage of large materials. The USR-permitted mining operation
has been in place for almost 20 years,the transload operation will not cause any significant changes for the surrounding
landowners. The USR requirements already address weed control and waste disposal. The transload operations would
be under the same requirements.
G. I. Goal 7. Recognize the importance of railroad infrastructure to some industrial uses.
The proposed use is consistent with this part—the proposed use will use the current Union Pacific main line,the private
rail spur within the USR property, and possibly expand the spur as warranted by future projects. Because the USR-
permitted mining operation has been in place for almost 20 years, and has used the rail line for the duration, the transload
operation will not cause any significant changes for the surrounding landowners.
3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning)
and the zone district in which it is located.
Sec. 23-3-40. Uses by special review.
R.Any use permitted as a Use by Right, an ACCESSORY USE, or a Use by Special Review in the COMMERCIAL or
industrial zone districts,provided that the property is not a Lot in an approved or recorded subdivision plat or lots
parts of a map or plan filed prior to adoption of any regulations controlling subdivisions. PUD development proposals
shall not be permitted to use the special review permit process to develop.
AA. More than one (1)cargo container per legal lot or parcel.
• Sec. 23-3-330. 1-3(Industrial)Zone District.
C.Accessory Uses. The following BUILDINGS, STRUCTURES and USES may be allowed in the 1-3 Zone Districts
so long as they are clearly incidental and accessory to the Use Allowed by Right. Such BUILDINGS, STRUCTURES
and USES must be designed, constructed and operated in conformance with the performance standards set forth in
Sections 23-3-340, 23-3-350 and 23-3-360 below.
1. OFFICES for USE by operators of the Use Allowed by Right.
2. Loading areas or STRUCTURES.
3. Parking areas or STRUCTURES.
The proposed use is consistent with Weld County Code,Chapter 23, Division 1 A(Agricultural)Zone District, Section 23-
3-40- Uses by Special Review, Parts R and AA. The proposed use is also consistent with Weld County Code, Chapter
23, Division 4 Industrial Zone Districts, Section 23-3-330, Part I-3 (Industrial)Zone District.
The proposed use is consistent with 23-3-40 Part R because it is a use permitted as a Use by Special Review and the
property is not a Lot in a Subdivision plat. The proposed use is consistent with 23-3-40 Part AA because there may be
more than one(1) cargo container used on the property at any one time, depending on the temporary projects.
The proposed use is consistent with 23-3-330 because the proposed use as a transload yard will require accessory
Loading Areas, Parking Areas, and possibly temporary trailers used as offices as listed in this part.
4. What type of uses surround the site (explain how the proposed use is consistent and compatible with
surrounding land uses).
The proposed transload area is within an approved mining USR. Both uses within the USR are industrial in nature, so are
compatible with each other. The mining and transload operations both use the rail spur within the property, the interior
haul road to the north entrance of the site, and in the case of storm events,the detention pond that is already in place for
the mining operation will certainly be able to accommodate runoff from the transload lease areas.
• The proposed use is compatible with surrounding uses outside of the permitted property also. The surrounding uses are
varied and include: a Weld County gravel pit to the south, agricultural lands(rangeland), a natural area to the east (Lone
Tree Creek—which will not be affected), and to the west is the Union Pacific rail line which will be used to bring in the
transload materials. West of the rail line and County Road 21, and north of the proposed use is the Town of Carr.

QUESTIONNAIRE
• The end use of the property will be rangeland, as was already approved for the USR. This will be compatible with all
surrounding uses.
Please see the answers to questions 2 and 3 for a description of how this use is compatible to the Weld County
Comprehensive Plan and parts of the Weld County Code and the Agricultural Zone district.
5. Describe, in detail,the following:
5.a.Number of people who will use this site
Persons using this site will include LGE employees(estimated 5-6), leaseholder transload crews (estimated 5-10),truck
drivers (estimated 10-20),vendors (estimated 1-2), and other miscellaneous visitors and inspectors(estimated 1-2). All
transload projects will vary, and LGE will send Weld County detailed information on each project prior to its start.
The leaseholder companies'transload crews will vary depending on the quantities of, and the type/size of materials to be
transloaded. LGE can only make a rough estimate that leaseholder crew sizes will generally be 5-10 people for unloading
railcars and loading-out trucks. The crews will only be on site for a few days/weeks to unload railcars and then load-out
trucks. Leases are temporary and will generally run 6 months or less.
The number of trucks (i.e.truck drivers) on site will vary with each transload project and the load-out schedule. A very
rough estimate is 8-12 truck drivers per day during load-out times. The load-out to trucks is estimated to take a few days
to a few weeks depending on the size and schedule of the transload project.
LGE will contact Weld County prior to each project and give more details and better estimates on the crew size and
trucking schedule for the specific project.
Note: Although LGE is not requesting any changes to the permitted mining operation, LGE would like Weld County to
know that the mining operation is significantly decreased, which has resulted in a decrease in the number of LGE
employees present on site—around 5-6 employees.
• 5.b.Number of employees proposed to be employed at this site
The estimated number of LGE employees present on site-around 5-6 employees.
5.c.Hours of operation
The hours of the mining operation are not changing.
LGE requests extended hours for the proposed transload operation. There may be projects when the trains or trucks will
come in to the Carr site for unloading over a weekend and when loading-out via rail or truck will have to be scheduled
during weekend or nighttime hours.
If Weld County requests, LGE,the leaseholder, and/or the trucking companies will contact Weld County any time that
extended hours will be needed for a project.
5.d.Type and number of structures to be erected (built)on this site
There will be no buildings built on this site in relation to the proposed use.
The current private rail spur may be extended to form a complete loop to allow for more efficient transloading. The
proposed rail spur is shown on the Carr Transload Area map,attached for your reference.
5.e.Type and number of animals, if any,to be on this site
There will be no animals on this site in relation to the proposed use.

WELD COUNTY SITE SUFIC DEVELOPMENT PLAN AND USE •PECIAL REVIEW(USR)
QUESTIONNAIRE
• 5.f. Kind of vehicles (type,size,weight)that will access this site and how often
The vehicles that will access the site for the proposed use may include: unit trains with the transload materials for storage,
regular sized trucks(18-wheelers) and oversized trucks to load-out the materials, and passenger vehicles.
The number, size, length and weight of trucks needed for load-out will vary with each project. LGE will contact Weld
County with vehicle details for each project prior to the start of the project.
Some of the vehicles that may be typical to be used on-site for the transload operations are as follows:
- Trains
- Cranes—40-ton,60-ton, 100-ton
- Forklifts—5-ton, 10-ton
- Trucks—18-wheelers, specialized trucks for oversize loads
See an traffic example for a typical windmill transload project in the"Traffic Study Information"section of this application.
5.g.Who will provide fire protection to the site
Nunn Fire District will continue to provide fire protection to the site. This is not a change.
5.h.Water source on the property (both domestic and irrigation)
This proposed new use is temporary—under 6 months,therefore no water source is required. Regardless, no water will
be needed for the proposed transload operations.
If any dust suppression is needed for roads or other areas within the leased areas, LGE can supply water from the water
right that LGE has on the Lone Tree Creek. The right is absolute and allows pumping up to 150 acre-feet/year, contingent
upon water availability in the creek. The water right also allows a 20-acre-foot storage capacity. This is not a change.
• 5.1. Sewage disposal system on the property(existing and proposed)
No sewage disposal system will be needed for the proposed transload operations due to the temporary nature of the
projects—6 months. Furthermore, as explained above,transload crews are only on site to unload materials for storage
and then to load-out materials for transport. The crews are only on site for a few day/weeks at load-in and load-out and
then are not on site during the period of storage.
5.j. If storage or warehousing is proposed,what type of items will be stored
No buildings or warehousing will be needed for the proposed transload operations. Some projects may bring in one or
more cargo containers or trailers to store small items necessary to the transload operation.
6. Explain the proposed landscaping for the site.The landscaping shall be separately submitted as a
landscape plan map as part of the application submittal.
There is no change needed to the landscape plan from what is already in place with the current USR mining and
reclamation plans. When the mining is completed and the transloading operations cease,the site will be reclaimed as
rangeland—which is the currently approved reclamation in the USR and state permits. Please see the attached Carr
AmUSR-840 plat maps for reference to what is already approved for the overall permitted property.
No additional screening from adjacent properties and public rights-of-way is needed. As mentioned above,there will be
no buildings. There is already screening in place in the form of a vegetated topsoil stockpile that runs about 200 feet,
starting from the rail spur and goes south,which will screen the operations from public view. Furthermore,the area
designated to be various leaseholds has already been mined, and is slightly lower than the land to the west of the
permitted boundary, the Union Pacific Rail Road (UPRR) line, and Weld County Road 21.

WELD COUNTY SITE SPIOFIC DEVELOPMENT PLAN AND USE EOPECIAL REVIEW(USR)
QUESTIONNAIRE
• 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity
occurs.
The reclamation for the leased areas will be same as the method used and approved for the Carr USR: Stripped topsoil
and overburden are replaced in the excavated portions of the mining (and transload)operation by scrapers. The
overburden is replaced first, and then about 6-8 inches of topsoil is replaced. The area will be revegetated by drill
seeding, using the grass seed mix that has been already approved for the state reclamation permit. Permanent,
sustainable revegetation of the backfilled areas of the site are established within one or two years. This method of
reclamation has resulted in very successful and permanent grass stands on the reclaimed areas of the current permit site.
There are no trees or shrubs on the leased area to be disturbed, so none will be installed for reclamation.
8. Explain how the storm water drainage will be handled on the site.
Sufficient drainage control and capacity is already in place for the Carr USR. No new drainage controls will need to be
constructed (unless the rail spur loop is completed). Various drainage controls include man-made and natural controls.
The ground at the Carr site is highly permeable and stormwater soaks in to the soil before it can"run off."
A large detention pond which has been used as a stormwater detention pond for the mining operation is available and will
be used as a detention pond for the leased areas. The pond is located in the southeast section of the proposed leased
area. This pond is shown on the Carr Transload Area map. This pond is more than large enough to accommodate any
storm water flows from all of the leased areas. The lease areas are not new acreage, but acreage that has been part of
the permit since it was approved, so the drainage controls have already been working for these areas—they will just be
designated as transload areas.
Any storm water within the leased area will flow and drain naturally from the northwest to the southeast—where the
detention pond is located.
• All of the leased area south of the original east-west rail spur has been mined and graded and is therefore lower than
surrounding areas. To the west, and outside the property, is the Union Pacific Rail line—stormwater flows from west to
east, so the rail line will not be affected by the leasehold area. To the east there is a interior haul road just outside the
leased area that is higher ground, so this road will prevent any stormwater runoff from going father east to Lone Tree
Creek. To the south,this area is mined, and partially reclaimed, and any stormwater flows that happened to come this
way would be welcome to help with vegetative growth.
If the proposed rail spur loop is constructed, a culvert will be constructed under the southeast"corner"of the loop, which
will allow stormwater run-off to naturally drain to the detention pond from the leasehold areas to the west.
If and when the mining operation processing plant and settling ponds are removed and the area to the north of the rail
spur is leased, one of the settling ponds will remain as a stormwater detention pond.
9. Explain how long it will take to construct this site and when construction and landscaping is
scheduled to begin.
The area south of the rail spur that is to be leased for the proposed transload operation has already been mined and is
graded. The area north of the rail spur that may be leased after the mining processing plant is removed has not been
mined. All areas to be leased are stabilized due to having heavy mobile equipment(loaders, scrapers, haul trucks, over-
the-road trucks)traveling over the areas for the past twenty years. There will be no buildings or other permanent
structures needed for the leasehold areas because all uses are temporary. Therefore,the areas to be leased do not need
any preparation or construction. If and when the rail spur is increased to create a full loop, the land around it will be
stabilized and compacted prior to leasing for transload operations.
No landscaping is needed for the leasehold areas because they are already shielded from public view by the vegetated
topsoil berm described in Question 6. Landscaping the leasehold areas is not necessary due to the temporary nature of
the projects. Furthermore,the nature of the proposed use—temporary storage of large transloaded materials, moving
those materials from rail to storage area, load out of the materials by truck—all proposed transload operations would
• hinder landscaping and vegetative growth.
Reclamation will be carried out for the leased areas when the entire USR site is shutting down. Reclamation will be
carried out as described above in Question 7.

WELD COUNTY SITE S•IFIC DEVELOPMENT PLAN AND USE SPECIAL REVIEW(USR)
QUESTIONNAIRE
• 10. Explain where storage and/or stockpile of wastes will occur on this site.
The proposed transload operation does not generate waste per se since it is strictly an operation of handling(unload, load
out)and storing transloaded products.There may be a minimal amount of inert trash, including consumer waste(food
wrapping, drink containers). This minimal waste will be properly handled, stored,and disposed of in a manner that
controls fugitive dust, blowing debris and other nuisance conditions. Trash receptacles, including, but not limited to lidded
trash cans and dumpsters shall be used within each leasehold to contain any trash/waste. All wastes shall be removed
for final disposal in a manner that protects against surface and groundwater contamination. The Carr USR already has a
waste/trash disposal service which will be used by the transload operations as well. There will be no stockpiling of waste.

Please see attached Weld County Road Access Information sheet.
The main access to/from Weld County Roads into the site is on the south side of Weld County Road 126, east of
the Town of Carr, east of the Union Pacific Railroad line, and west of a bridge over Lone Tree Creek. The access
is already existing and has been used by the permitted sand and gravel mining operation for many years.
This main access is the access that will be used for the additional proposed use—transload/storage yard.
The access/entrance to the Carr Gravel Resource was improved last year to Weld County specifications and
approval. The access was widened to at least 150-foot radius and the gate at the entrance was moved farther
back into the site to accommodate the widened entry and allow for the oversize vehicles that are used for
transporting transloaded materials. The fence on either side of the gate was also moved to allow for the widened
150-foot radius entrance.

SITE NAME: CARR GRAVEL RESOURCE
PERMIT: WELD COUNTY- 2n° AmUSR#840
USE: GRAVEL MINING AND TRANSLOAD / STORAGE OPERATIONS
GRAVEL MINING OPERATIONS
A dust abatement plan is already in place for the mining operation. It is required by the state (CDPHE-Air
Quality Control Division) as part of the air permit for the site. The Dust Abatement Plan was submitted to
Weld County and approved in 2001, as part of the first USR amendment. There is no change needed for
this plan in regards to the second amendment.
TRANSLOAD/STORAGE OPERATIONS
Weld County Environmental Health has requested a Dust Abatement Plan for the lease hold areas, as
part of the second USR amendment in 2010.
1. L.G. Everist can supply water to leaseholders from the Everist Well for dust control.
2. A water truck will be located on site for use in dust control. If the water truck is not available, another
means of spreading water on roads for dust control will be performed (example—front end loaders
• can fill their buckets with water and then tip down slightly to spread the water).
3. The leaseholders will have access to the water and to the water truck or other water spreading
equipment. The leaseholders may also supply their own water spreading equipment.
4. Speed limits will be limited in the leaseholder areas to 30 m.p.h. (which is the maximum allowed
speed throughout the entire site and mining operations).
5. Haul roads shall be graveled and/or compacted to control fugitive dust.
6. Chemical stabilizers may be used (per manufacturers' instructions) on haul roads, staging areas, and
other travelways as needed.
7. Leaseholders will be required to ensure that no off-property transport of visible dust emissions shall
occur.

WELD COUNTY SITE SPADIC DEVELOPMENT PLAN AND USE B•ECIAL REVIEW(USR)
DRAINAGE REPORT INFORMATION
• USR#: Am-USR-840
Site Name: Carr Gravel Resource
Applicant: L.G. Everist, Inc. (LGE)
Summary: The applicant is applying for additional uses at the Carr Gravel Resource, AmUSR-840. The
proposed use would be in addition to the approved mining and reclamation plans that are already
permitted. This application is not making any changes to the mining/reclamation operation. The
proposed use we are applying for is a transload/storage yard within the site. The transload
projects would all take place within an approximately 300-acre transload area, and would be
temporary-6 months or less. See the Weld County Site Specific Development Plan and Use by
Special Review Questionnaire for more details on the proposed use.
The proposed transload yard is an overlay use on an already permitted USR. The USR has drainage structures
in place that have been working for years, and will continue to be more than adequate for the additional use by
the transload/storage yard. See the map titled, "Carr Transload Area, Exhibit A"for drainage structure location.
Because this is a permitted site, and adequate drainage structures are already in place, we are not being required
to do a Preliminary Drainage Report. We are submitting information on the site and the existing drainage
structures for your review.
As noted in the Weld County Site Specific Development Plan and Use by Special Review Questionnaire:
8. Explain how the storm water drainage will be handled on the site.
Sufficient drainage control and capacity is already in place for the Carr USR. No new drainage controls will need to be
constructed (unless the rail spur loop is completed). Various drainage controls include man-made and natural controls.
• The ground at the Carr site is highly permeable and stormwater soaks in to the soil before it can"run off."
A large detention pond which has been used as a stormwater detention pond for the mining operation is available and will
be used as a detention pond for the leased areas. The pond is located in the southeast section of the proposed leased
area. This pond is shown on the Carr Transload Area map. This pond is more than large enough to accommodate any
storm water flows from all of the leased areas. The lease areas are not new acreage,but acreage that has been part of
the permit since it was approved, so the drainage controls have already been working for these areas—they will just be
designated as transload areas.
Any storm water within the leased area will flow and drain naturally from the northwest to the southeast—where the
detention pond is located.
All of the leased area south of the original east-west rail spur has been mined and graded and is therefore lower than
surrounding areas. To the west, and outside the property, is the Union Pacific Rail line—stormwater flows from west to
east, so the rail line will not be affected by the leasehold area. To the east there is a interior haul road just outside the
leased area that is higher ground, so this road will prevent any stormwater runoff from going father east to Lone Tree
Creek. To the south, this area is mined, and partially reclaimed, and any stormwater flows that happened to come this
way would be welcome to help with vegetative growth.
If the proposed rail spur loop is constructed, a culvert will be constructed under the southeast"corner" of the loop,which
will allow stormwater run-off to naturally drain to the detention pond from the leasehold areas to the west.
If and when the mining operation processing plant and settling ponds are removed and the area to the north of the rail
spur is leased, one of the settling ponds will remain as a stormwater detention pond.
Additional information regarding the site, additional transload use, and drainage:
The sand and gravel deposit is shallow-only 10-12 feet-and all of it is above groundwater level. Therefore, no
groundwater de-watering is needed. The mine is operated as a dry mine. This is not a change.
• The transload/storage use will not need any water operationally, nor any water storage.
C-WELD-SiteSpec&USR-Drainage)nfo-2010.doc
WELD COUNTY SITE SP•IC DEVELOPMENT PLAN AND USE B•ECIAL REVIEW(USR)
DRAINAGE REPORT INFORMATION
• Using the formulas in the Drainage Criteria Manual and permeability number that we received from Weld County,
we can show that the detention pond in the leasehold area is more than adequate to contain all stormwater flows.
1. Permeability = 40%, which converts to a Total Imperviousness Ratio(i) = 0.6
2. Figure SQ-2, Water Quality Capture Volume (WQCV), 80th Percentile Event- has formula for WQCV and
multiple drain time variables.
WQCV= a*(0.91 i3— 1.19i2 + 0.78i) = 1 *(0.91*.63— 1.19*.62 + 0.78*.6) = 0.23616
Note: 40-hour drain time = a = 1.0
3. Required Storage = [WQCV/ 12] *Area = (0.23616/ 12) * 300 acres leasehold area= 5.9 acre-feet
The calculations above show that a detention pond of 5.9 acre-feet would contain the flows from 300 acres.
The surveyed limits of the detention pond in the leasehold area at the top slope equals 3.53 acres. Assuming a 3
to 1 slope at 13 feet deep, this equates to a storage volume of approximately 37 acre-feet, more than adequate to
contain stormwater events.

TRAFFIC STUDY INFORMATION
• USR#: Am-USR-840
Site Name: Carr Gravel Resource
Applicant: L.G. Everist, Inc. (LGE)
Summary: The applicant is applying for additional uses at the Carr Gravel Resource, AmUSR-840. The
proposed use would be in addition to the approved mining and reclamation plans that are already
permitted. This application is not making any changes to the mining/reclamation operation. The
proposed use we are applying for is a transload/storage yard within the site. The transload

temporary-6 months or less. See the Weld County Site Specific Development Plan and Use by
Special Review Questionnaire for more details on the proposed use.
L.G. Everist, Inc. believes that a Traffic Study is not warranted as this time due to the temporary and varied nature
of future transload projects (i.e. quantity of trucks, size of trucks, and length of hauling schedule) and the
significant decrease in our mining operation.
However, Weld County believes a traffic study is needed for this amendment, so L.G. Everist is getting a traffic
study done by CH2M Hill. The traffic study will be submitted under separate cover.
The following paragraphs detail traffic-related information that is known or estimated at this time.
Weld County Road Agreement and designated haul route on Weld County roads
L.G. Everist, Inc. (under the operator name of Andesite Rock Company) is already in a Long-Term Road
Maintenance and Improvements Agreement with Weld County, dated February 28, 2001, and with a record
number 2831899, recorded March 12, 2001. This agreement could be updated to include: the updated company
• name, and the preferred west-bound haul route on WCR 126 for oversize trucks. The current agreement already
noted the east-bound route as going out the north entrance and east along WCR 126 (once the road had been
paved). The east bound route should remain allowable for non-oversize trucks.
The Weld County recommended haul route for haul trucks associated with this proposed use is: Enter/Exit from
the Carr AmUSR-840 north entrance to Weld County Road 126 and travel to/from the west to Interstate 25. An
alternative route, dependent on the size and weight of the trucks, and on Weld County approval, would be to
travel to the east on Weld County Road 126 to State Highway 85.
Note: Although WE is not requesting any changes to the permitted mining operation, LGE would like the County
to know that the mining operation is decreased, which has resulted in a decrease in aggregate traffic.
Oversize transportation permits
LGE understands that transportation of many of the transloaded materials by tractor trailer will require oversize
permits. The transload/leaseholder and trucking companies will be responsible for getting all the necessary
oversize permits from Weld County and CDOT. The transload and trucking companies will work with Weld
County Public Works with each project to determine the best route to take for the materials'final destination.
Please note that trucks that are used for oversize loads are specifically designed to accommodate the cargo so
that the maximum weight on any one axle does not exceed state and county road weight limits.
Temporary Nature of the Traffic
The transload/storage projects are temporary projects. The unloading to Carr will primarily be done from rail (on-
site, not affecting Weld County roads). The load-out to trucks is estimated to take a few days to a few weeks
depending on the size and schedule of the transload project. There could be more than one transload project in
• storage or transloading at a time.

TRAFFIC STUDY INFORMATION
• Truck traffic example for a typical windmill transload project at Carr Gravel Resource
Transload project would consist of(a) railing in windmill components, (b) off-loading and storing components, (c)
trucking out components. Example of a transload project for traffic estimates:
- 44 Full Turbines= 352 total components or less
- 3 Blades trains = 132 blades= 1 truck per blade
- 2 Tower trains = 88 sections (tops and midsections) = one truck per tower section
- 1 Nacelles/Hub/Container train =44 nacelles, 44 Hubs, 44 20ft containers = one truck per component
- Trucking for 7 to 8 weeks, Monday thru Saturday
- Six (6) turbines delivery per week = 8 to 9 trucks per day=48 to 54 trucks per week
LGE will contact Weld County prior to each project and give project details including, but not limited to, dates of
the project, quantity of materials being trucked out of the site, and trucking schedule. Leaseholders or trucking
companies will apply for oversize permits as needed.

DATE: April 7,2010
Purpose
The purpose of this Technical Memorandum is to evaluate traffic conditions at the L.G.
• Everist Gravel Resource Site near Carr, Colorado in conformance with Weld County traffic
impact study guidelines.
Introduction
In addition to gravel production,L.G. Everist has historically utilized the Carr site for
various uses ranging from temporary pipeline material storage to wind turbine offload and
delivery. Located just east of the Union Pacific Railroad tracks, the site is an ideal location
for transferring railroad cargo to trucks for final delivery. Since the site uses have varied in
the past,L.G. Everist contracted CH2M HILL to complete a traffic impact study to consider
multiple ongoing uses that would represent a conservative estimate of traffic impacts for
uses currently planned at the site. While it is not anticipated all of following uses would
occur simultaneously,for purposes of this analysis it is assumed that these would overlap
and occur during the summer months in 2010:
1) Ongoing site excavation for gravel production
2) Suncor Energy crude oil pipeline material storage and delivery
3) Wind turbine offload and delivery for a Wyoming energy project
A similar traffic study was recently completed and approved by Weld County for just the
pipe yard (pipeline storage and delivery) traffic impacts. The combined traffic impacts of
the three simultaneous uses is analyzed and summarized in this study. Many of the
conclusions drawn from the previous report that are not dependant on traffic volume have
been repeated for completeness.

DEN/LGEVERIST_CARRGRAVELRESOURCE FINAL TISDOC 1
TRAFFIC IMPACT STUDY FOR THE CARR GRAVEL RESOURCE SITE
• Existing Conditions
Site Description
As shown in Exhibit 1, the rail transload/storage yard is within the L.G. Everist Carr Gravel
Resource, is approximately 300 acres, and is located in the NE Sec 35,T 11N, R67W
southeast of Carr,CO. A lease agreement for the Suncor Energy crude oil pipeline material
storage and delivery is in place. An area will be marked off to designate their lease area and
prevent pipeline vehicles from interacting with gravel mining operations. Similarly,the
typical wind turbine offloads and deliveries for the Wyoming wind energy projects have a
separate and distinct area of operation on the site. A conservative estimate of traffic impacts
assumes all of the heavy vehicle traffic expected from the site will utilize the recently
improved access to the north of the site on Weld County Road 126 (WCR 126).
Adjacent Roadways
Nearest to the site,the current road system consists of private and county roads. According
to Weld County,WCR 126 is a paved 2-lane east-west major road (collector) also known as
Stevenson Avenue. It has a speed limit of 30 mph near the site access which is just west of
the Lone Tree Creek Bridge. According to the Colorado Department of Transportation
(CDOT), I-25 is a 4-lane rural north-south interstate with a speed limit of 75 mph. The WCR
126 1/2 intersects 1-25 at a diamond interchange and leads to the site eventually becoming
WCR 126. The I-25 interchange has a narrow 2-lane bridge over I-25 and the ramps are
controlled by stop signs. A frontage road parallels 1-25 on the east side and has a closely
spaced intersection adjacent to the interchange. U585 is a rural minor arterial in rolling
terrain with a speed limit of 65 mph. Both I-25 and US85 are designated as national truck
• routes.
Traffic Counts
Based on available traffic data,WCR 126 near WCR 21 carries approximate 422 daily
vehicles of which 38% are trucks. While the posted speed limit in this area is 30 mph, the
recorded 85th percentile speed is 49 mph. CDOT maintains an automatic traffic recorder
(ATR#153)location at the I-25 and Carr interchange. This count location continuously
records traffic data on I-25 and in 2008 I-25 carried an average armual daily traffic volume of
17,000 vehicles and approximately 15% trucks. The peak hour traffic at this location
comprises 11% of the daily traffic. The closest count available on U585,just north of WCR
108, indicates an existing average annual daily traffic count of 2,100 vehicles with roughly
19% trucks. Like I-25, approximately 11% of the daily traffic occurs in the peak hour.

TRAFFIC IMPACT STUDY FOR THE CARR GRAVEL RESOURCE SITE
• Trip Generation/Distribution
A conservative estimate of traffic expected on-site during the day and during the peak hours
for the three site uses results in a total of 87 vehicles (50 cars and 37 trucks) per day,of
which 54 are assumed to access the site during the peak hours (50 cars and 4 trucks).These
estimates assume the truck traffic is evenly distributed throughout the day and all of the on-
site personnel arrive and depart during the peak hours resulting in over 60% of the daily
site traffic occurring in the peak hours. This also assumes some on-site time for truck
loading so that trucks arriving during the peak hour do not depart in the same hour. The
following summarizes the assumptions used to determine these trip generation estimates.
Gravel Operations
Based on data maintained by L.G. Everist, the gravel operations occur approximately 250
days per year and have historically generated between 3 and 15 trucks per day. For 2010,
the site is expected to generate 8 trucks per day. On site personnel are assumed to generate
10 cars per day. This represents approximately 11 new peak hour vehicles that will be
destined for I-25 in support of gravel production operations. (Gravel trucks primarily use
WCR 126 to 1-25 which is the routing assumed in this analysis. However,more
infrequently, trucks are permitted to go both east and west on WCR 126 to US85 and 1-25 as
well as out the southern gate along WCR 120 to US85).
Pipe Yard
Estimates from Suncor indicate that there will be 5 full time employees located on the site
and up to 15 people may be onsite at any one time including haul truck drivers,equipment
• operators and visitors. It is anticipated that operations at the pipe yard will generate 50
daily vehicles of which 20 would be heavy trucks and the remaining 30 would be smaller
support vehicles. This represents approximately 32 new peak hour vehicles that will be
destined for US85 north of WCR 126 in support of construction operations expected to occur
from February to July 2010.
Wind Turbine
The site may also be utilized for a possible wind energy project in 2010. Wind turbine
• components are delivered via rail and ultimately trucked to Wyoming for installation. A
typical wind project consists of 44 full wind turbines or 352 total components or less. The
following summarizes the typical wind turbine components and associated truck deliveries:
• 3 Blades trains = 132 blades = 1 truck per blade = 132 trucks
• 2 Tower trains = 88 sections (tops and mids only) = one truck per tower section= 88
trucks
• 1 Nacelles/Hub/Container train =44 nacelles,44 Hubs,44-20ft containers= one truck
per component= 132 trucks
• One complete turbine requires 9 trucks
For a wind project of this size, trucking deliveries typically last for 7 to 8 weeks. Deliveries
occur 6 days per week Monday through Saturday. It is expected that approximately 6
turbines would be delivered per week resulting in approximately 9 trucks per day. On site
personnel are assumed to generate 10 automobile trips per day. This represents
approximately 11 new peak hour trips that would be destined for I-25 for wind turbine
• deliveries in support of a typical Wyoming wind energy project.

TRAFFIC IMPACT STUDY FOR THE CARR GRAVEL RESOURCE SITE
Level of Service
• In order to assess the potential traffic impacts associated with the proposed multiple uses at
the site,existing traffic conditions were analyzed both with and without the expected
additional site traffic during the peak hour. Since the peak hour is 11% of the daily volume
based on annual CDOT traffic counts along I-25 and US 85, the same peak hour percentage
was assumed for all other study area roadways. Therefore, only a single peak hour was
analyzed for freeway,highway, and intersection operations. Also, due to the lack of
available data,turning movement counts were estimated at the unsignalized site access and
WCR 126 intersection.
The operating conditions, or Level of Service (LOS), for I-25,US 85, and WCR 126; and the
unsignalized intersection of WCR 126 and the site access were assessed using Highway
Capacity Manual freeway,two-lane highway,and unsignalized intersection methodologies,
respectively. LOS is a term used to describe operating conditions in a traffic stream and
motorists' perceptions of those conditions. Six LOS classifications are given a letter
designation from A to F with "A" representing the best operating conditions and "F" the
worst. LOS D or better is typically considered acceptable for peak hour operations.
For freeways,LOS is determined by the density of traffic in a basic freeway section defined
by passenger cars per mile per lane. For two-lane highways,LOS is defined in terms of
average travel speed and percent time spent following another vehicle. For unsignalized
intersections, LOS is defined in terms of average delay per vehicle by movement. The
method incorporates delay associated with deceleration,acceleration, stopping, and moving
up in the queue. For side street stop-controlled intersections, delay is typically represented
• in seconds for the minor street approaches and the left turns from the major street.
As shown in Exhibits 2 and 3, the freeway segment,highway segment, and site access
intersection analyzed operate at acceptable levels of service and the additional site
generated traffic creates minimal impact to the existing peak hour traffic operations near the
site.

The truck percentages on-site and on the surrounding roadways is lower than existing due to the increase in personnel vehicles accessing the
site and the fact that site generated truck traffic occurs throughout the day not just during the peak hours.

The combined site uses for the gravel operations,pipe yard,and wind turbine delivery
represent a conservative estimate of traffic volume for uses currently planned at the site.
The rural nature of the surrounding area and historically low traffic growth trends suggest
that impacts identified under existing conditions would also occur under future conditions.
Since site generated traffic is not anticipated to increase beyond this conservative estimate,
any change in traffic operations would be attributable to growth in background traffic. For
• these reasons,future traffic conditions have not been analyzed. Should the uses on the site
change substantively, additional traffic analysis would be required.
Impacts
The highest increase in traffic on WCR 126 is expected just east of the site access resulting in
a daily traffic volume increase of 1.00 trips (50 vehicles);which represents approximately
24% more traffic than the current 422 daily volume on WCR 126. The increase in traffic due
to the site activities is not expected to appreciably impact traffic operations on WCR 126,
US85, or I-25. The expected vehicle mix is similar to that of the existing traffic,truck traffic
will be distributed throughout the day, and the increase in traffic will occur on a temporary
basis.
Other Considerations
Signing and Striping
Based on aerial photographs and initial site assessment,it appears that signing and striping
in the area is adequate and well maintained. Should site uses or planned operations change
substantively or extend beyond the expected 6 month period, "Trucks Entering Highway"
warning signs could be implemented to warn drivers on WCR 126.
Sight Distance
The posted speed limit on WCR 126 near the site access is 30 mph but the recorded 85th
percentile speed is 49 mph. This higher observed speed was used to assess sight distance at
the site access. AASHTO stopping sight distance guidance suggests 425 feet at 50 mph.
•
DEN/LOEVERIST CARRGRAVELRESOURCE FINAL_TIS.DOC 6
TRAFFIC IMPACT STUDY FOR THE CARR GRAVEL RESOURCE SITE
• While the site access is located on a slight horizontal curve, there appears to be no vertical or
horizontal sight distance issues or obstructions with the sight distance triangles extending
east and west of the access along WCR 126. Furthermore, the access provides entering sight
distance in excess of the CDOT access code requirement of 650 feet for trucks entering a 2-
lane roadway.
Pavement Maintenance
No pavement assessment was performed as part of this analysis. However, based on aerial
and available site photographs, it appears the pavement condition of I-25, US 85,and WCR
126 is similar to that of other area rural highways and adequately accommodates the
existing truck traffic. Due to the modest traffic generated by the site and the short duration
of planned uses, a need for long term pavement maintenance beyond that which is already
completed by the State or County is not anticipated. Should long term maintenance
agreements be required,L.G. Everist will negotiate this with the County.
Intersection Turning Radii
The majority of the trucks expected at the site will be standard single unit semitrailers with
a wheelbase of 62' or less (WB-62). The software AutoTurn was used to determine the
turning radii of typical trucks at the WCR 126 site access. Using a conservative estimate of
the intersection dimensions, the full width of the access road would be needed to facilitate
the WB-62 truck turning radius. This would also result in some off tracking of the rear
wheels and possible encroachment into the opposing lane of traffic.
Given the sheer size and length of the trucks required for delivery of the wind turbine
• components,the site owner L.G. Everist has widened the access road onto WCR 126,moved
their gate south,and added approximately 300 feet of recycled asphalt to create an all
weather intersection approach. This access has successfully accommodated trucks of similar
dimensions for the delivery of wind turbines in the past. Entering traffic at the site access
onto WCR 126 will likely require special traffic control due to the larger vehicles. The trucks
will be routed west on WCR 126 and then north on I-25. The bridge at the WCR 126 1/2
interchange over I-25 is narrow with no shoulders and may present a challenge to negotiate
for the larger vehicles. The contractor will obtain necessary oversize and overweight vehicle
permits and confirm the planned haul route with the County and CDOT.
Acceleration and Deceleration Lanes
Assuming requirements of the CDOT state highway access code for rural highways, the
peak hour volume at the westbound to southbound left turn lane (17 vph) into the site does
exceed the 10 vph for a left turn deceleration lane. The right turn lane volumes at the site
access do not exceed the thresholds of 25 vph for a right turn deceleration lane, or 50 vph for
a right turn acceleration lane. Acceleration and deceleration lanes at the site access on WCR
126 are not recommended due to the low traffic volumes on WCR 126 and the fact that
should all three site uses occur simultaneously,the left turn lane volume of 17 vehicles per
hour would be a temporary condition.
Requirements, Restrictions, and Permits
Given the operations at the site and multiple planned uses, roads and highways may be
impacted by vehicles hauling materials from the site. Contractors will comply with existing
• federal, state,and county requirements and restrictions to protect the road network and the
DEN/LOEVERIST_CARRGRAVELRESOURCE FINAL TIS.DOC 7
• TRAFFIC IMPACT F OR THE CARR GRAVEL RESOURCE SITE
traveling public. In addition, load limits will be observed at all times to prevent damage to
• existing road surfaces. Arrangements to transport oversized loads will he coordinated with
and approved by CDOT.
Summary and Conclusions
This traffic impact study considers multiple overlapping uses at the Carr Gravel Resource
Site. While not expected to occur simultaneously,the three site uses (gravel, pipeline, and •
wind turbine) represent a conservative estimate of traffic impacts for uses currently planned
at the site. The three site uses are expected to generate a combined 87 new daily vehicles
with most of the trips occurring in the peak hours. Truck traffic would be distributed
throughout the day.
Traffic operational analysis indicates that I-25, US85, WCR 126, and the site access
intersection will operate at acceptable levels of service and the additional site generated
traffic creates minimal impact to the existing peak hour traffic operations near the site. The
site access and surrounding roadway network appear to have well maintained signing and
striping. The site access sight distance is adequate with no obstructions and the pavement
condition on WCR 126 is not expected to be degraded by site activities due to the short
duration of operations.
The site is not expected to generate enough traffic to warrant any significant infrastructure
improvements;and acceleration and deceleration lanes are not recommended. Due to the
size and larger turning radius of the wind turbine haul trucks,special care should be taken
by drivers when entering and exiting WCR 126 at the site access and near the I-25
interchange to avoid vehicle conflicts. The contractor will obtain any necessary oversize and
• overweight vehicle permits from CDOT and confirm the planned haul route with the
County.
Included at the end of this memo are the Highway Capacity Manual level of service
definitions for freeways,2-lane highways, and unsignalized intersections as well as the
Highway Capacity Software level of service reports for traffic operations at and near the
site.
The above report has been prepared according to national and state standards and in
conformance with Weld County traffic impact study guidelines.

• HCM 2-LANE HIGHWAY LEVEL OF SERVICE CRITERIA
LOS Description
A Motorists are able to travel at their desired speed. Without strict enforcement, this highest
quality would result in average speeds of 55 mph or more on two-lane highways in Class 1.
The passing frequency required to maintain these speeds has not reached a demanding
level,so that passing demand is well below passing capacity, and platoons of three or
more vehicles are rare. Drivers are delayed no more than 35 percent of their travel time by
slower-moving vehicles. A maximum flow rate of 490 pc/h total in both directions may be
achieved with base conditions. On Class II highways, speeds may fall below 55 mph,but
motorists will not be delayed in platoons for more than 40 percent of their travel time.
B Traffic flow is speeds of 50 mph or slightly higher on level terrain Class 1 highways. The
demand for passing to maintain desired speeds becomes significant and approximates the
passing capacity at the lower boundary of LOS B. Drivers are delayed in platoons for up to
50 percent of the time. Service flow rates of 780 pc/h total in both directions may be
achieved with base conditions. On Class II highways, speeds may fall below 50 mph,but
motorists will not be delayed in platoons for more than 55 percent of their travel time.
C Flow increases, resulting in noticeable increases in platoon formation,platoon size and
frequency of passing impediments.The average speed still exceeds 45 mph on level
terrain Class 1 highways,even though unrestricted passing demand exceeds passing
capacity. At higher volumes the chaining of platoons and significant reductions in passing
capacity occur. Although traffic flow is stable, it is susceptible to congestion due to turning
traffic and slow-moving vehicles. Percent time-spent-following may reach 65 percent of the
time. Service flow rates of 1,190 pc/h total in both directions may be achieved with base
conditions. On Class II highways, speeds may fall below 45 mph,but motorists will not be
delayed in platoons for more than 70 percent of their travel time.
• D LOS D represents unstable flow. The two opposing traffic streams begin to operate
separately at higher volume levels, as passing becomes extremely difficult. Passing
demand is high, but passing capacity approaches zero. Mean platoon sizes of 5 to 10
vehicles are common, although speeds of 40 mph still can be maintained under base
conditions on Class 1 highways. The proportions of no-passing zones along the roadway
section usually has little influence on passing. Turning vehicles and roadside distractions
cause major shock waves in the traffic stream. Motorists are delayed in platoons for nearly
80 percent of their travel time. Maximum service flow rates of 1,830 pc/h total in both
directions may be achieved with base conditions. On Class II highways, speeds may fall
below 40 mph, but in no cases will motorists be delayed in platoons for more than 85
percent of their travel time.
E Traffic flow conditions have a percent time-spent-following greater than 80 percent on
Class 1 highways and greater than 85 percent on Class II. Even under base conditions,
speeds may drop below 40 mph. Average travel speeds on highways with less than base
conditions will be slower, even down to 25 mph on sustained upgrades. Passing is virtually
impossible and platooning becomes intense as slower vehicles or other interruptions are
encountered. The highest volume attainable under LOSE defines the capacity of the
highway, generally 3,200 pc/h in both directions. Operating conditions at capacity are
unstable and difficult to predict. Traffic operations seldom reach near capacity on rural
highways, primarily because lack of demand.
F Represents heavily congested flow with traffic demand exceeding capacity. Volumes are
lower than capacity and speeds are highly variable.
Source: Highway Capacity Manual(HCM),2000.
Primary measures for service quality for Class 1 facilities are percent time-spent-following and
average travel speed. For Class 2 facilities the measure for service quality is based on percent time-
spent-following.

Dear Kim:
It has been a few months since L.G. Everist, Inc. ("LGE") representatives met with Weld
County officials regarding the transloading of windmill components at our Can
Operation facility ("Carr"). Since the meeting, LGE's intentions and predictions have
changed due to the current economic climate. This letter will serve as an update to our
• business plans at Can going forward.
Regarding the mining operations at Can, LGE successfully bid on a concrete paving job
on I-76. To complete this job, we will put Can into production for the remaining 2009
season. Once the material is in stockpile, we will shut-down and load-out the materials in
stockpile. Once the stockpiles are loaded out (we estimate this to be in the 2nd quarter of
2010), we will shut-down the Can mining operations. This shutdown will be for an
indefinite period of time; operations will resume when it is economically viable to do so.
As Weld County is aware, windmill components were shipped into Can and transloaded
onto trucks in the 2nd and 3`d quarters of 2009. This project was very short-lived and
temporary—as is the case with all windmill projects. All conditions must be perfectly
aligned before windmill components for a windmill project are shipped into Can, i.e. the
location of the manufactured windmill component, the location of the successful bidder
on the windmill project, and the location of the construction site of the windmill project.
The bottom line is that all windmill projects come with extremely unpredictable timing.
Regarding the pipeline project with Suncor, it is currently in the logistic planning stage.
The pipe will come in by rail, and we are told this will start in the 4th quarter of 2009.
The pipe will be unloaded from rail and stored for a short period of time. All stored pipe
will be shipped to the construction site by the 4th quarter of 2010. All outbound trucks
loaded with pipe will not require over-weight permits. There have been several delays on
this project; however, this is the best forecast that we at this time.
• • Kim Ogle
August 28, 2009
Page 2 of 2
• Presently, we forecast the Carr mining operation will be shut-down by the end of 2010.
We see no windmill projects on the horizon but will continue to explore opportunities.
The pipeline project is something that has been on the books for a couple of years and
once the project is complete, we anticipate no future pipeline projects.
With all factors considered, we respectfully request that Weld County and LGE personnel
not undertake the lengthy amendment process at this time. We propose that if a transload
opportunity does come our way, we will immediately address it with Weld County
officials on a case-by-case basis. Frankly, I do not forecast any long term, permanent
opportunities in the Northern Weld County area.

J

Kim,
In response to your questions:
What is meant by the storage of rail cars, e.g., what duration of time that these cars would sit idle on
the track?
Rail cars parked on our private rail spur. This is certainly no change from having the rail cars on the
track in relation to the mining operation.
Duration : unknown
What is meant by minor maintenance? To what structure/ vehicle would this activity occur on, or in?
Saddles would be attached to flat rail cars. The saddles would be attached in order to be able to put
windmill blades on the flat cars.
What happens to the materials associated with the minor maintenance?
• The "materials" are the saddles and they will be attached to the rail car.
What "devices" will be implemented to monitor these activities, if approved?
We will have leases to allow storage of rail cars on our private rail spur.
Frankly, we think that this use fits right in with the amended transload/storage use that is already being proposed.
Sincerely,
