RE: Adequacy Review 1 Preliminary Review of a 112 Construction Materials Reclamation Permit
Application Package, Hunt Farms, Hunt Dirt Mine #2, File M-2024.037; Response
Dear Mr. Girardi:
This letter is being generated to satisfy the adequacy review dated September 18., 2024 for David and
Kayleen Hunt's, Strear Dirt Mine, File M-2024-037. The italicized items are the current comments, and the
bold text are the responses:
Rule 6.4.1- Exhibit A- Legal Description:
1. In accordance with Rule 6.4.1(2), please revise Exhibit A to indicate the location of the main entrance to
the mine site showing latitude and longitude or Universal Transverse Mercator (UTM) coordinates. Please
specify coordinates of latitude and longitude in degrees, minutes and seconds or in decimal degrees to an
accuracy of at least five (5) decimal places (e.g., latitude 37.12345 N, longitude 104.45678 IN). For UTM,
the operator will need to specify North American Datum (NAD) 1927, NAD 1983, or WGS 84, and the
applicable zone, measured in meters.
The Site access location has been included.
SITE ACCESS LOCATION:
40°16'31.79"N
104°48'24.49"W
Application Pages and Rule 6.4.2- Exhibit B — Index Map:
2. Pages 1, 3, and 8 of the application included the Applicant/Operator 'Name' listed as "David Hunt". On
Exhibit B Index Map, the Applicant/Operator's name was listed as "Hunt Fanns, LLC". Upon review of the
Secretary of State's registered businesses, the business "Hunt Farms, LLC" was listed. Please revise the
Applicant/Operator Name to be consistent throughout the application.
The applicant and operator is David and Kayleen Hunt, the maps have been changed to reflect this.
Rule 6.4.3- Exhibit C- Pre -mining and Mining Plan Maps(s) of Affected Lands:
3. The Division only received two maps titled "Mine Plan, Sheet C-2" with the application submission. If
there is a Map C-1 in the application package, it was not submitted. The two "Mine Plan, Sheet C-2" maps
are not the same map. Please revise these maps with distinct titles so that they maybe differentiated and
provide Map C-1 if applicable.
Exhibit C-1 "Existing Conditions" has been included.
4. The permit boundary appears to encompass the Hunt Irrigation Pond, DRMS permit No. M-2022-050.
Does the Applicant intent to absorb the mining and reclamation of permit M-2022-050 into the Stear Dirt

Mine affected area? If not, please specifically identify the location of this permit on the Exhibit C and F maps
and clearly indicate the lands affected by this operation are not associated with the Stear Dirt Mine affected
area. If the Applicant intends to absorb the mining and reclamation of permit No. M-2022-050 into the Stear
Dirt Mine affected area, please update the application exhibits accordingly to address this area.
The applicant wishes to absorb permit M-2022.050 into this permit. The M-2022-050 permit is a
111(b) permit which, as of the last DRMS inspection in March 2024, has finished mining and is
currently being reclaimed. The quantities for reclamation have been increased to incorporate
seeding the disturbed areas around the pond and the overburden stockpile.
5. The permit acreage according to the first page of the application is 277.0 acres. Upon review of Exhibit C,
the permit boundary symbol extends outside of "Parcel 1", (#105729100002) and "Parcel 2"
(#105729000021) as described in Exhibit A. Upon review of these parcels on the Weld County GIS Hub,
Parcel 1 is 295.75 acres and Parcel 2 is 0.25 acres. These two parcels total 296 acres in size and the permit
boundary extends beyond these parcels. The Division estimated the permit boundary to be approximately
356.73 acres in size based on the Exhibit C, Mining Plan Map provided. Please clarify this discrepancy and
revise all the applicable maps to clearly define the 277.0 acre permit area.
The permit area of 277.0 acres is based on parcel boundaries determined during the land survey plat
(rounded up from 276.98). See the attached copy of the survey. The Weld County GIS calculates the
area of the parcels and is not accurate. The Division's estimate is likely based on the 200 foot buffer
line, the permit boundary has been thickened in relation to the 200 foot buffer line.
6. Please revise and/or provide a map with the following information:
a. All adjoining surface owners of record.
b. There appears to be structures/buildings within 200 feet of the affected area. Please revise the map to
show the name of these structures.
c. Show the owner's name, type of structures, and location of all significant, valuable, and permanent man-
made structures contained on the area of affected land and within two hundred (200) feet of the affected
land.
d. The existing topography of the area with contour lines of sufficient detail to portray the direction and rate
of slope of the affected land.
e. The type of present vegetation covering the affected land.
All of these aspects are included with Exhibit C-1. There is not a consistent type of vegetation over
the site as it is agricultural with rotating crops which are only present during the growing season.
7. Map C-2 includes a total of nine (9) gas wellheads owned by PDC Energy. In accordance with
Rule 6.4.3(b), please include the locations of oil and gas flowlines associated with the wellheads.
There are three (3) producing wells at the Site and all flowlines are shown on the maps. All wells
listed as (PA) are plugged and abandoned with associated infrastructure removed. The mine limit is
at least twenty (20) feet from the flowlines and one hundred and fifty (150) feet from the producing
wells.
8. Please revise the mining plan to indicate the total amount of land that will be affected within the permit
boundary.
The affected land is equal to the permit boundary.
9. Please include the anticipated general mining direction for the South Cell.
Page 3
Mr. Chris M. Girardi
September 19, 2024
The mining direction will be from the northeast to the southwest. This has been included in Exhibit
D.
10. See item #7 above and revise the narrative regarding gas wellheads and flowlines within the affected
area, and how will these features be protected from mining disturbance and reclamation activities.
All active oil and gas wells and flowlines are outside of the mine limit. Plugged and abandoned wells
are cut below grade.
11. Page D-1, subpart (a) indicates the permit boundary will be 277.00 acres +1--. See item #3 above and
revise this statement as necessary.
277.0 is correct.
12. Page D-2, subpart (b) states, "The mine was excavated down at a 3 to 1 horizontal to vertical
slope on the east, west and south side, along with feathering grades back into existing on the north
by Weld County Road 40." Please clarify what this sentence is referring to.
This section was removed as it essentially reiterated the mining section of subpart (a). Subpart (b)
now states:
Topsoil and overburden will be stripped with bulldozers, loaders or excavators and
stockpiled in the active mine phase. The mined area will be reclaimed to 4 -feet below
existing grade and tie into existing grade on the perimeter of the mine. This excavation
will be amended and planted with crops or dryland native grasses. Historic drainage
patterns will be maintained.
13. Page D-2, subpart (d) states that 10 acres will be disturbed during mining at any one time. Please
explain this further. What will these 10 -acres consist of, such as excavation, haul roads,
stockpiles, etc.? Please update the Exhibit C map to depict these 10 -acre phases.
The Applicant typically mines 10 acres at a time. This is not meant to limit the amount that the
Applicant can actively mine which will depend on market conditions. It is also not meant to indicate
that there are any set 10 acre "phases" that the applicant will mine out. The Applicant intends to
reclaim concurrently with mining but does not propose a phased bonding approach and as such the
whole Site's reclamation will be bonded as if the whole Site has been disturbed without any
concurrent reclamation.
This subpart has been clarified to say:
Typically, up to 10 acres will be actively mined at any one time.
14. Page D-2, subpart (e) indicates the intent to mine approximately 100,000 tons of material per
year. Exhibit E, page E-1 states the intent to mine the North Ce// (which contains 76,000 cubic
yards of material) for one year, and the South Cell (which contains 866,000 cubic yard of material)
for two to four years. The rate of material to be mined per year given the volume of material in the
South Cell is insufficient for the proposed timeline of two to four years. Please clarify this
discrepancy in the mining and reclamation timeline.
This was a relic of a previous grading plan, this subpart has been changed to say:
Page 4
Mr. Chris M. Girardi
September 19, 2024
North Cell- mined in year one into year two and reclaimed concurrent with mining South
Cell.
South Cell — mined in year two through fourteen and reclaimed concurrently.
15. Page D-2, subpart (e) indicates that the North Cell will be reclaimed using waste material from
the South Cell. Subpart (a) of Exhibit E states the North Cell will be backfilled with overburden or
sand from the South Pit. Please clarify these statements and define what the waste material will
consist of, and subsequently why this waste material is suitable as backfill material.
The salable product for this mine is dirt (overburden and topsoil). The waste material
referred to is unsalable material that is contained in the current grading including sand or
sandy overburden that does not meet the needs of the purchasers. Page D-2 subpart e has
been updated to specify unsalable material (sand and overburden) instead of "waste
material". The addition of sand or unsalable overburden to the North Cell will not have a
deleterious effect on the proposed reclaimed use of the area.
16. Please clarify whether four feet will be the maximum desired depth for the North and South Cell
pits or the average depth of the pit.
An average depth of four (4) feet is the maximum desired depth for both pits.
17. In accordance with Rule 6.4.4), specify the dimensions of any existing or proposed roads that
will be used for the mining operation. Describe any improvements necessary on existing roads and
the specifications to be used in the construction of new roads. New or improved roads must be
included as part of the affected lands and permitted acreage. Affected land shall not include off -site
roads which existed prior to the date on which notice was given or permit application was made to
the office and which were constructed for purposes unrelated to the proposed mining operation and
which will not be substantially upgraded to support the mining operation. Describe any associated
drainage and runoff conveyance structures to include sufficient information to evaluate structure
sizing.
Subpart (j) has been added to Exhibit D which states:
A temporary dirt road will be constructed at the Site to allow access through the
existing fields. The road will be approximately twenty-four (24) feet wide and will
consist of clearing and grubbing the existing field and compacting the soil. The
road will be reclaimed from north to south as the mining operation progresses.
The road will be constructed at existing grade and will not require any drainage
or runoff conveyance structures.
18. The Applicant states they will stockpile topsoil and overburden during mining. Please clarify
how topsoil stored on the pit floor will be stabilized, protected from water erosion from storms, and
disturbance from concurrent mining operations.
Subpart (b) has been updated to state that topsoil stockpiles will be located "near" the
active mine phase.
Page 5
Mr. Chris M. Girardi
September 19, 2024
A stockpiling section has been added to subpart (a) stating:
Stockpiling:
Topsoil and overburden stockpiles that remain dormant for fourteen (14) days shall be
roughened, mulched, or tackified to stabilize them. Topsoil and overburden stockpiles
that remain dormant for more than one -hundred and eighty (180) days shall be seeded
with the Weld County upland seed mixture described in Exhibit E (Reclamation Plan).
19. Please clarify how the topsoil stripped and stockpiles for reclamation will be segregated,
preserved and stabilized from wind and water erosion before it is replaced.
Section 3.1.9 Topsoiling has been updated to state:
Section 3.1.9 Topsoiling: Three inches of topsoil will be removed and segregated
from other spoil. The topsoil will be blended with manure and used for reclamation.
Topsoil stockpiles shall be stored in places and configurations to minimize erosion
and located in areas separate from salable product where disturbance by ongoing
mining operations will be minimized. Once stockpiled, topsoil shall be rehandled as
little as possible. Stockpiles that remain dormant for fourteen (14) days shall be
roughened, mulched, or tackified to stabilize them. Stockpiles that remain dormant
for more than one -hundred and eighty (180) days shall be seeded with the seed
mixture described in subsection (f).
20. Please demonstrate how only three inches of topsoil will be sufficient to accomplish the
reclamation plan and ensure that cropland post -mine land use is accomplished.
The top soil be mixed with manure provided by the operators facilities (the applicant owns a
feedlot) and nitrogen fixing crops will be planted to build soil from the sand/overburden
below. See the attached letter specifying the process.
21. Please clarify the timing of reclamation in relations to the proposed 10 -acre phases. At what
point will the mined area be prepared for topsoil replacement and seeding, and will an entire 10 -
acre phase be reclaimed before initiating mining in a new 10 -acre phase?
The mined area will be prepared for topsoil replacement and seeding after reaching final
grade. The Applicant will typically mine 10 acres at a time. More than 10 acres may be
actively mined at any one time, based on market conditions. Final grading will be
completed as soon as feasible after mining in an area is complete. For instance, if an area
is likely to be disturbed by mine vehicles or equipment then the Applicant will wait on final
grading until a point that the area will no longer be disturbed. The total area disturbed by
mining may exceed 10 acres before it is feasible to begin final grading and topsoiling.
The Applicant is not proposing a phased bonding approach and the whole Site's
reclamation will be bonded even though the Applicant intends to reclaim as mining
progresses.
Page 6
Mr. Chris M. Girardi
September 19, 2024
22. For any internal haul roads within the affected area created, please explain when and how
these features will be reclaimed.
The internal haul roads will be mostly located in future mined areas. In these areas the
roads will be mined out and the area will be reclaimed as future cropland.
The first six hundred (600) feet of the access road will remain after reclamation to provide
access to the reclaimed land use.
23. Page E-2, subpart (c) indicates the Applicant may have the intent to drill auger holes. If drill or
auger holes, test pits, soil boring holes, or monitoring wells are intended to be added to the mining
plan, please submit a Technical Revision prior.
Any drilling, or test pits will be performed within the affected area and will be abandoned in
accordance with State Regulations. All monitoring wells installed at the Site will obtain a
monitoring well permit from the State Engineer (Department of Water Resources). Drilling
or auger holes, test pits, soil boring holes, or monitoring wells will not affect the proposed
Reclamation Plan.
24. Page E-3, subpart (c) under Section 3.1.8 indicates that forbs, shrubs, and tree species will be
replaced during reclamation. Please update the reclamation plan to provide details of these
plantings.
Plantings will be graminoids as listed in the Reclamation Plan. The references to forbs,
shrubs and trees has been removed from this section. Exhibit F-1 has been updated to
show areas where crops will be used and where the seed mix will be used.
25. Page E-5, subpart (t)(ii) indicates the reclamation plan map includes a list of plant materials
and seeding to be utilized. This map does not include this information. Please revise.
The lists from the Reclamation Plan have been added to Exhibit F-1.
26. Page E-5, subpart (t)(v) indicates manure will be applied at 5 tons per acre. If 277 acres will be
affected, 1,385 tons of manure will be required. Using the 1.5 tons per cubic yard conversion,
about 923.3 cubic yards of manure will be required not 333 cubic yards as indicated on Page E-5.
Please revise this page accordingly.
Not all of the acres in the affected area are planned to be reseeded. The total area where
topsoil will be removed and replaced is approximately 222.2 acres. Page E-5 has been
updated to reflect that the tons of manure required is 1,111 tons.
27. Page E-5, subpart (t)(iv) refers the Division to a letter discussing reclamation in more depth.
Please submit this letter and clearly identify where it is located within the permit application
package. If it is an appendix to the application and exhibits, please indicate this.

The letter has been included with this adequacy response.
28. If the Applicant decides to change the post -mine land from cropland, the applicant would need
to apply for and receive approval of an amendment application. Please acknowledge.
Acknowledged.
29. The Applicant states the Operator owns a sufficient amount of irrigation water and intends to
use this water resource during revegetation. Please provide the well permit number of the irrigation
well intended to be used.
The Applicant owns 1110 of 1 share of the Farmers Independent Ditch (FIDCO) which is
currently used to irrigated the property with center pivots.
Rule 6.4.6- Exhibit F- Reclamation Plan Map:
30. The topography of the north cell is not depicted on the Exhibit F map. Please revise the map to
show the topography of the north cell with sufficient detail to portray the direction and rate of slope.
The topography of the north cell will be reclaimed to the existing grade. The map has been
updated to show topography in this area.
31. Please revise the reclamation plan map to portray the proposed final land use of each portion
of the affected land.
The map has been updated to show the crop extent which is irrigated by center pivot, the
existing pond created under permit M-2022.050, and the alternative seed mixture planting.
Rule 6.4.7- Exhibit G- Water Information:
32. Page G-1, subpart (c) indicates the mine area drains internally, and any releases will be
controlled. However, it appears based on the topography of the Exhibit C and F maps that the site
will drain to the east/southeast for the South Cell and it is unclear how the site will drain in the north
cell. Please provide a plan on how stormwater will be contained within the affected land and how
releases will be controlled.
The North Cell will drain into the pit until reclamation when the final grading will mirror the
historic drainage pattern. Trapped rainwater in the North Cell during active mining will be
pumped to an approved discharge point.
The South Cell will be graded to allow for stormwater to follow historic drainage patterns to
the east.
The text in Exhibit G has been updated to reflect this.
33. Will any water be used for dust control? If so, please provide the project water requirements
including flow rates and annual volumes for development, mining and reclamation, and please
identify the source of the water. If multiple sources will be used, please indicate the projected
amount from each of the sources of water to supply the project.
Page 8
Mr. Chris M. Girardi
September 19, 2024
Dust control will come from a water truck filled offsite at the Applicant's stockyard which
has well permits: 0666, 0665, and 0664.
Rule 6.4.9- Exhibit 1- Soil Information:
34. This exhibit indicates the soil types on the site are shown on Exhibit C-1. As discussed in item
#3, an Exhibit C-1 map was not submitted. Please submit this exhibit.
Submitted.
35. Based on the plan to salvage and replace three inches of topsoil, please update this exhibit to
provide a description of the suitability of the salvaged topsoil in terms of depth and quantity for the
establishment and maintenance of plant growth.
See attached letter.
Rule 6.4.12- Exhibit L- Reclamation Costs:
36. Please note the Division will develop a cost estimate to complete reclamation at the site, which
will be provided in the future.
Acknowledged.
Rule 6.4.10- Exhibit J- Vegetation Information:
37. In accordance with Rule 6.4.10(c) revise this exhibit to provide an estimate of the average
annual production of the crops produced at the site.
Exhibit J has been updated to indicate the historical crop production is approximately 27
tons of corn silage per acre.
Rule 6.4.19- Exhibit S- Permanent Man-made Structures:
38. The requirements for this exhibit have not been addressed. Where the affected lands are within
two hundred (200) feet of any significant, valuable and permanent man-made structure, the
applicant shall:
a. provide a notarized agreement between the applicant and the person(s) having an interest in
the structure, that the applicant is to provide compensation for any damage to the structure; or
b. where such an agreement cannot be reached, the applicant shall provide an appropriate
engineering evaluation that demonstrates that such structure shall not be damaged by
activities occurring at the mining operation; or
c. where such structure is a utility, the Applicant may supply a notarized letter, on utility letterhead,
from the owner(s) of the utility that the mining and reclamation activities, as proposed, will have "no
negative effect" on their utility. The applicant will need to attempt to obtain structure agreements
required under subpart (a) above for all significant, valuable, and permanent man-made structure
within 200 feet of the affected land. The applicant will need to provide documentation that this
attempt was made (proof of mailing for structure agreements and notices was provided to the
Page 9
Mr. Chris M. Girardi
September 19, 2024
Division on 9/4/2024). Please provide copies of the notices, letters, and structure agreements sent.
If agreements cannot be reached, then the applicant can address the rule requirements by
complying with subpart (b) and/or (c).
Properties and structures located within two hundred (200) feet of the affected land
boundary are listed on Exhibit C-1 (attached). As indicated, structure agreements have
been sent out to the owners listed and proof of mailing was provided to the Division. The
structure agreements were not scanned before being sent off but the agreement between
the Well Augmentation Subdistrict of CCW has been returned and has been included as an
example of the agreements sent out. As indicated in Exhibit S, the proposed mining
operation will pose no risk to surrounding structures due to the shallow excavation. All
existing structures have a minimum offset of twenty (20) feet which is well outside of the
failure radius for a four (4) foot excavation.
A copy of the notices has been included and returned structure agreement has been
included.
39. As indicated above in item #3, Exhibit C-1 was not submitted with the application, please
provide this exhibit.
Included.
General Comments:
40. The Division received comments from the Colorado Parks and Wildlife, the Colorado Division of
Water Resources, and the Weld County Department of Planning Services. The comment letters
are attached for your review. Please acknowledge and address the comments noted in the letters
and make changes to the application as necessary.
Acknowledged. See comments below.
SEO:
1. The Town of Gilcrest is approximately twenty (20) feet in elevation below the Site
and depth to groundwater at the Site was determined in the M-2022.050 application
to be a maximum elevation of 4750' or twelve (12) feet below the lowest elevation
encountered at the Site.
2. There are no plans for stormwater detention at the Site. During the active mining of
the North Cell, stormwater will flow into the pit and will be pumped to an approved
discharge point. During the active mining of the South Cell historic flow patterns will
be maintained and best management practices will be used and described in a
Stormwater Management Plan. The Operator will apply for a CDPS discharge permit
from CDPHE.

MINE PLAN
EXHIBIT D - MINING PLAN
This information provided in this Exhibit is intended to satisfy the requirements outlined in Section
6.4.4 of the Colorado Mined Land Reclamation Board Construction Material Rules and
Regulations:
(a) Description of the method(s) of mining to be employed in each stage of the
operation as related to any surface disturbance on affected lands;
The proposed amendment area includes a significant deposit of harvestable
overburden used for reclamation soil in oil and gas operations located west of the
Town of Gilcrest in Weld County. The site is located east of the Farmers Independent
Ditch, south of Weld County Road 42, north of Weld County Road 40 and west of
Weld County Road 29. The permit boundary / affected land boundary will include
277.0 acres +/-.
Existing Conditions and Site Preparation:
Existing Conditions
The proposed mining area is actively being farmed as irrigated farm land.
Site Preparation
Very little site preparation is required, stripping the topsoil and stockpiling on the
perimeter of the site.
Minin
North Cell — to be stripped 4 -feet, stockpiled and sold. The cell will be mined at 3:1
horizontal to vertical side slopes to approximately 4 -feet below existing grade.
South Cell — to be stripped 0 to 4 -feet, stockpiled and sold. Mining will start in the
northeast and will progress to the southwest ending closest to the access. The cell will
be mined along the southwest at a 3:1 horizontal to vertical side slope approximately
4 -feet below existing grade. The cell will be feathered to existing grade along the
eastern side of the site to allow for historical drainage patterns.
The operator will develop and comply with a Stormwater Management Plan and Spill,
Prevention, Control and Countermeasures Plan. The operator will notify the Division
of Mine Safety and Reclamation in the event of a reportable spill.
Processing:
All material mined under this proposed application will be transported by excavator,
loader or haul truck to the stockpile area.
Stockpiling:
Topsoil and overburden stockpiles that remain dormant for fourteen (14) days shall be
roughened, mulched, or tackified to stabilize them. Topsoil and overburden stockpiles
David Hunt - Strear Dirt Mine — MLRB 112 Permit Amendment Application
Exhibit D -1
that remain dormant for more than one -hundred and eighty (180) days shall be seeded
with the Weld County upland seed mixture described in Exhibit E (Reclamation Plan).
Import Material:
The Miner may import material from and export material to other sites. The applicant
is aware that in accordance with Rule 3.1.5(9) of the Construction Material Rules and
Regulations, if any offsite material is used as backfill, a notarized letter will be
submitted to the Division indicating the materials are inert. The applicant will supply
such a letter to the Division if, at the time of Reclamation, the applicant intends to use
off -site material as backfill.
(b) Earthmoving;
Topsoil and overburden will be stripped with bulldozers, loaders or excavators and
stockpiled near the active mine phase. The mined area will be reclaimed to 4 -feet
below existing grade and tie into existing grade on the perimeter of the mine. This
excavation will be amended and planted with crops or dryland native grasses. Historic
drainage patterns will be maintained.
All water diversions and impoundments; and
There will no dewatering or water impoundments onsite.
The size of area(s) to be worked at any one time.
Typically, up to 10 acres will be actively mined at any one time.
An approximate timetable to describe the mining operation. The timetable is for
the purpose of establishing the relationship between mining and reclamation
during the different phases of a mining operation.
The Operator anticipates that mining will commence as soon as all permits are in
place. The Operator anticipates extracting approximately 100,000 tons of reclamation
soil per year, however, production rates may vary based on market demands.
Timetable for Mining and Reclamation
There is approximately 1,413,000 tons of soil material which will provide 14 years of
reserves. The North Cell contains approximately 114,000 tons of material which is
anticipated to take approximately 1 year to mine after which unsalable material (sand
and overburden) from the South Cell will be utilized to reclaim the North Cell back to
native grade.
Reclamation will begin immediately after mining is complete. When possible,
concurrent reclamation practices will be used to minimize site disturbance and to limit
material handling to the greatest extent possible. Please refer to the Mining Plan Map
in Exhibit C for phase areas to be mined, locations and areas.
David Hunt - Strear Dirt Mine — MLRB 112 Permit Amendment Application
Exhibit D - 2
(f Use Mining Plan Map in conjunction with narrative to present:
(i.)
Nature, depth and thickness of the deposit and thickness and type of
overburden to be removed
The depth of soil to be mined is 4 feet consisting mainly of silty sand.
(ii.) Nature of the stratum immediately beneath the material to be mined in
sedimentary deposits
The site is located approximately 15 miles east of the foothills of the Colorado
Front Range on the western flank of the Denver Structural Basin. The basin is a
downwarp of sedimentary strata that tends north-northwest, parallel to the
mountain front. In the project area, the sedimentary bed dips gently eastward
toward the axis of the basin east of the site. Based on regional geologic mapping
(Colton, 1978), the near surface bedrock in the project area is the Paleocene and
Upper Cretaceous Denver and Arapahoe Formations. The bedrock is overlain by
upper Pleistocene and Holocene (Quarternary age) gravel deposits and eolian
(wind blown) overburden soils. The gravel deposits exist primarily within the
Broadway Alluvium deposit. The bedrock unit consists mainly of claystone and
may contain lenses of siltstone and sandstone.
(g) Identify the primary and secondary commodities to be mined/extracted and
describe the intended use.
The primary commodities are reclamation fill; intended for construction materials.
(h) Name and describe the intended use of all expected incidental products to be
mined/extracted by the proposed operation.
There are no expected incidental products to be mined.
(i) Specify if explosives will be used in conjunction with the mining (or reclamation)
No explosive material will be used on -site.
(j) Specify the dimensions of any existing or proposed roads that will be used for
the mining operation. Describe any improvements necessary on existing roads
and the specifications to be used in the construction of new roads. New or
improved roads must be included as part of the affected lands and permitted
acreage. Affected land shall not include off -site roads which existed prior to the
date on which notice was given or permit application was made to the office and
which were constructed for purposes unrelated to the proposed mining
operation and which will not be substantially upgraded to support the mining
operation. Describe any associated drainage and runoff conveyance structures
to include sufficient information to evaluate structure sizing.
David Hunt - Strear Dirt Mine — MLRB 112 Permit Amendment Application
Exhibit D - 3
A temporary dirt road will be constructed at the Site to allow access through the
existing fields. The road will be approximately twenty-four (24) feet wide and will
consist of clearing and grubbing the existing field and compacting the soil. The road
will be reclaimed from north to south as the mining operation progresses. The road
will be constructed at existing grade and will not require any drainage or runoff
conveyance structures.

Exhibit D - 4
EXHIBIT E — RECLAMATION PLAN
This information provided in this Exhibit is intended to satisfy the requirements outlined in Section
6.4.5 of the Colorado Mined Land Reclamation Board Construction Material Rules and
Regulations: The proposed mining and reclamation plan focuses on minimizing the ecological
impacts of mining, minimizing the length of time of impact, and maximizing long-term benefits.
North Cell— mined in year one into year two and reclaimed concurrent with mining
South Cell.
South Cell — mined in year two through fourteen and reclaimed concurrently.
(a) A description of the type(s) of reclamation the Operator proposes to achieve in the
reclamation of the affected land, why each was chosen, the amount of acreage
accorded to each, and a general discussion of methods of reclamation as related to
the mechanics of earthmoving;
The mined area will be reclaimed to 4 -feet below existing grade and tie into existing grade
on the perimeter of the mine. The mine will include a 20 -foot buffer around the perimeter
of the excavation.
The North Cell will be excavated at a 3 to 1 horizontal to vertical slope and will be
backfilled back to native grade with overburden or sand from the South Pit.
The South Cell will be excavated down at a 3 to1 horizontal to vertical slope on the
southwest side, along with feathering grades back into existing on the east by Weld
County Road 29.
All excavation will be amended and planted with crops or dryland native grasses. Historic
drainage patterns will be maintained. Refer to Exhibit F for the acreages and additional
details.
Earthmovinq
The soil amendment will be placed by a loader and generally graded with a blade. All
grading will be done in a manner that controls erosion and siltation of the affected lands, to
protect areas outside of the affected land from slides and other damage. In addition, all
backfilling and grading will be completed as soon as feasible after the mining process. All
disturbed areas will be regraded and smoothed to a finished grade that is suitable for
revegetation of the final land use. See attached mining plan for historic and proposed
grades.
As noted previously, the area will be reclaimed as mining commences. Finish grading,
topsoil/soil amendment placement and seeding will occur once the resource is completely
removed per phase.
(b) A comparison of the proposed post -mining land use to other land uses in the
vicinity and to adopted state and local land use plans and programs.
David Hunt — Strear Dirt Mine — MLRB 112 Permit Amendment Application
Exhibit E -1
Once the site is reclaimed it can returned to being farmed.
(c) A description of how the Reclamation Plan will be implemented to meet each
applicable requirement of Section 3.1.
The Operator will carry reclamation to completion with reasonable diligence. Reclamation
will be completed within one to two years from completion of mining, but not more than five
years from the date the Operator informs the Board or Office that such phase has
commenced.
Section 3.1.5 Reclamation Measures Material Handling: Grading will be performed to
help control erosion and siltation of the affected lands through phased mining,
implementing good operation techniques to handle material as little as possible, and
vegetation of stockpiles remaining in place for more than one growing season. Although
the use of erosion protection devices is not anticipated, if deemed necessary by the
operator at the time of excavation, silt fence and haybale dams will be installed to prevent
erosion. Backfilling and grading will be completed as soon as feasible after the mining
process is complete.
Maximum slopes and slope combinations will be compatible with the configuration of
surrounding conditions and selected land use. Mining will occur at a slope that is stable.
The site will be reclaimed to grades 0 to 4 feet below pre -mining elevations.
The operator will backfill using fill material generated on -site, or imported inert fill
generated outside the permit area. If any inert off -site material is used as backfill, a
notarized letter will be submitted to the Division as required by Section 3.1.5(9) of the
MLRB Construction Material Rules and Regulations.
It is not anticipated that mining will uncover any refuse or acid-forming or toxic producing
materials, however if any such materials are encountered the operator will take precaution
to handle the materials in a manner that will control unsightliness and protect the drainage
system.
Drill or auger holes that are part of the mining operation shall be plugged with non-
combustible material, which shall prevent harmful or polluting drainage. Any test pits, soil
boring holes, or monitoring wells not located within the mine excavation limits will be
plugged as soon as it can be confirmed that they are no longer needed for the operation.
Mined material to be disposed of within the affected area will be handled in such a manner
so as to prevent any unauthorized release of pollutants to the surface drainage system.
No unauthorized release of pollutants to groundwater shall occur from any materials
mined, handled or disposed of within the permit area.
Section 3.1.6 Water -General Requirements: The Operator will comply with applicable
Colorado water laws governing injury to existing water rights and with applicable state and
federal water quality and dredge and fill laws and regulations.
David Hunt — Strear Dirt Mine — MLRB 112 Permit Amendment Application
Exhibit E - 2
The operator will develop and comply with a stormwater management plan and will use
best management practices (BMPs) to ensure groundwater and surface water are
protected to the greatest possible extent. BMPs include schedules of activities,
prohibitions of practices, maintenance procedures and other management practices to
prevent or reduce the pollution in runoff from the site.
Section 3.1.7 Groundwater - Specific Requirements: The Operator will comply with the
applicable standards and conditions for classified and unclassified groundwater.
Groundwater will not be exposed or dewatered.
Section 3.1.8 Wildlife: The mining and reclamation plans have been designed to account
for the safety and protection of wildlife on the mine site. The Operator will use concurrent
reclamation methods to minimize the impact on wildlife. The proposed reclamation plan
may improve wildlife habitat. The proposed plantings will create improved cover, foraging,
roosting, and nesting areas for wildlife. Control and/or removal of noxious and weedy
species during the project and the replacement of desirable graminoid species during
reclamation will result in enhancement of wildlife habitat on the project site.
Section 3.1.9 Topsoiling: Three inches of topsoil will be removed and segregated from
other spoil. The topsoil will be blended with manure and used for reclamation. Topsoil
stockpiles shall be stored in places and configurations to minimize erosion and located in
areas separate from salable product where disturbance by ongoing mining operations will
be minimized. Once stockpiled, topsoil shall be rehandled as little as possible. Stockpiles
that remain dormant for fourteen (14) days shall be roughened, mulched, or tackified to
stabilize them. Stockpiles that remain dormant for more than one -hundred and eighty
(180) days shall be seeded with the seed mixture described in subsection (f).
Section 3.1.10 Revegetation: In those areas where revegetation is part of the
reclamation plan, the land shall be revegetated in a manner that establishes a diverse,
effective, and long-lasting vegetative cover. The proposed seed -mix or plantings for
reclamation are outlined on the Reclamation Plan included in Exhibit F of this application.
The quarter section of land has a sprinkler and irrigation water and this infrastructure will
remain and be utilized for irrigation purposes.
Section 3.1.11 Buildings and Structures: Please refer to the enclosed Reclamation Plan
included in Exhibit F.
Section 3.1.12 Signs and Markers: The Operator will post appropriate signage at the
entrance to the mine site. The permit area will be marked by existing fencing, or proximity
to existing County roads.
(d) Plans for topsoil segregation, preservation and replacement; for stabilization,
compaction and grading of spoil; and for revegetation.
Topsoil will be removed and segregated from other spoils. Topsoil not needed for
reclamation may be sold or removed from the site. For reclamation, topsoil will be
replaced by a scraper and generally graded with a blade. Grading shall be done in a
manner that controls erosion and siltation of the affected land and protects areas outside
David Hunt - Strear Dirt Mine — MLRB 112 Permit Amendment Application
Exhibit E - 3
the affected land from damage. In addition, backfilling and grading shall be completed as
soon as feasible after the mining process.
Final grading will create a final topography that is appropriate for ultimate land use. For
example, grades on the site will maintain historic drainage. Topsoil will be uniformly
placed and spread on areas disturbed by the mining. The minimum thickness shall be 3
inches above the surrounding excavated grade, consistent with existing topsoil depths on -
site. The topsoil shall be keyed to the underlying and surrounding material by the use of
harrows, rollers or other equipment suitable for the purpose. The owner is as active farmer
in the area and has the ability to maintain and ensure the reclaimed land will be suitable for
the proposed use.
The Operator plans to plant crops for use in their feed lot operation. In the event crops are
not used, areas where perennial seed revegetation is part of the reclamation plan, the
Operator will revegetate the land in such a manner so as to establish a diverse, effective,
and long-lasting vegetative cover that is capable of self -regeneration without continued
dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural
vegetation of the surrounding area. Seed will be drilled and mulched. The Operator owns
a sufficient amount of irrigation water to establish an effective ground cover. In the event a
dryland crop is utilized the Operator will more than likely continue to irrigate the ground
allowing for more production for use in feedlot operations. The Operator currently uses
this method on their other Weld County farms.
The revegetation seeding and plant list on the Reclamation Plan Map contains the
preferred species of grasses, shrubs and trees to be planted.
Seeding will take place once final grading and replacement of topsoil have been
completed. Timing of seeding will be consistent with standard horticultural practice for
dryland applications - generally between late September and the middle of April to ensure
there is adequate moisture for germination.
(e)
A plan or schedule indicating how and when reclamation will be implemented.
Include:
i. An estimate of the periods of time which will be required for the various stages or
phases of reclamation.

MEMORANDUM
TO: DRMS Hunt Dirt Mine #2, File M-2024-037
FROM: Civil Resources, LLC
DATE: September 23, 2024
RE: Reclamation attachment and qualifications
This memorandum summarizes the proposed reclamation for the Hunt Dirt Mine #2 and the operators ability to reclaim
the site to irrigated crop land. This memorandum is intended to supplement Exhibit E (Reclamation Plan).
Existing Use
The farm is currently irrigated crop land producing alfalfa, corn silage and pasture grass. The operator/applicant owns
Hunt Farms which has grown from operating two circles to successfully owning and operating thirteen irrigation systems
on over 1,200 acres of Weld County farmland over the last thirty years. Hunt Family Farms also pastures and feeds
7,000 head of beef cattle through its operations, utilizing the crops, aftermath, and irrigated pastures from the irrigated
farms to supply feed for its cattle operations. Mr. Hunt holds a degree in agronomy and has applied techniques to
increase crop yield across Hunt Farms. Using creative solutions to utilize irrigation water and varying crops, Hunt Farms
is a forward thinking irrigator along the historic US Highway 85 corridor in Weld County.
Proposed Use
The operator plans to excavate/harvest the upper soils and sell those as a reclamation product across Weld County.
This will provide nutrient rich soils for reclaimed sites and will improve these sites to allow for crop development.
The operator will segregate a minimum of 3 -inches of topsoil and mix that with manure from a near -by (adjacent) feed lot
to be applied to the fields in -turn promoting plant growth on these deep sandy loam soils. The operator owns and
operates a feed lot and this material is a byproduct of raising cattle. These uses are appropriate for the development of
irrigated crops and a reclaimed use of the manure. For example, sod farms continuously remove the top organic layer
and continue to replant the sod. The sod could be considered a cover crop that creates organic matter each season.
This will be very similar to the reclaimed use of hunt Dirt Mine #2 except that Hunt's is a one-time operation. The
proposed mining area also has native water rights in conjunction with an existing sprinkler system. The sprinkler will not
be removed during mining and once the soil is ready for planting it will be irrigated which will further ensure the success
of a cover crop. The operator proposes to plant alfalfa, legumes, or other cover crops to promote growth and rebuild the
reclaimed area.
Background Information
The operator has also discussed the proposed reclamation with various agronomists and attached to this memo is a
background data sheet discussing manure use and proposed cover crops for reclamation. The operator is currently
implementing this reclamation technique on the WC 40 Soil Mine (M2021030) with success.

Mineral Conditioners
Gypsum. Gypsum has long been recognized for
its benefits on high sodium -containing soils. Gyp-
sum is a mineral with the chemical composition
CaSO,•2H2O. It occurs in nature as soft crystalline
rock and varies in purity. Gypsum has been shown to
displace exchangeable sodium from the cation ex-
change sites of soils high in sodium. With irrigation or
dryland, gypsum can be used to reclaim saline areas or
slick spots, soften and crumble alkali hard pans, supply
calcium on low exchange capacity soils, and improve
infiltration for some puddled soils. Gypsum is not rec-
ommended on soils containing native gypsum or areas
irrigated with water containing abundant amounts of
calcium and magnesium.
The amount of gypsum to apply depends on the
purity of the gypsum and the quantity of sodium
present in the soil. Actual rates should be based on a
salt -alkali soil test. Application rates normally vary be-
tween 1 and 10 tons/acre. Gypsum applied at less than
500 pounds per acre will likely be of little benefit as a
soil conditioner, but may work as a calcium or sulfur
nutrient source.
Animal manure. Animal manures can be important
contributors to soil organic matter levels as well as sup-
pliers of various nutrients. Manure is largely composed
of partially decomposed plant material plus a wide vari-
ety of organisms. Many of the organic compounds in
manure are sinular to those found in soil organic mat-
ter. An application of 10 tons/acre of manure would
result in 0.5 to 2 tons of organic matter after decompo-
sition by soil organisms. Manure, however, contains
soluble salts which can be detrimental to soil physical
properties and crop growth when added in high
amounts, especially to arid soils.

Other organic conditioners. Other materials that can
serve as soil conditioners include crop residues, com-
post, sewage sludges, green manure crops, and saw-
dust. The effectiveness of the material varies with the
amount of material added and the C:N ratio. Sewage
sludges may contain potentially harmful levels of
heavy metals and other toxic materials and should be
analyzed for these materials before using.

Soil must always be covered with plants or plant litter
Rest groundcover from grazing, or grow green manure crops with minimum tillage
Or slash the groundcover oeriodically. Use high stock densities for short periods to place organic matter bothinand on the
soil (root pruning and litter trampling). On pasture cropping land, this may include one or two in -crop graze periods. Green
manure crops should be lightly incorporated, although animal impact is the prefeerred option.
The higher the biomass and turnover of plants roots, the faster new topsoil will form
A composty smell indicates high levels of biological activity, particuly fungi. The activites of benefical soil microbes are
important for the formation of soil aggregates which give soil its structure, improve porosity and water- holding capacity.
