PROPOSED DECISION
for
Approval of Permit Renewal
The Colorado Division of Reclamation, Mining and Safety, in accordance with C.R.S.
34-33-109(7), proposes to Approve the renewal of a permit to conduct surface coal mining and
reclamation operations at the Keenesburg Strip Mine, Permit No. C-1981-028.
This decision is based on a review of the complete and accurate application and the existing permit,
including all conditions and revisions approved up to September 7, 2011. In accordance with
C.R.S. 34-33-109(7)(a), the Division makes the following determinations which warrant that the
permit be renewed:
1. The terms and conditions of the valid, existing permit are being satisfactorily met;
2. The present surface coal mining and reclamation operation is in compliance with all
requirements of the Colorado Surface Coal Mining Reclamation Act, C.R.S. 34-33-101 et
seq., and the Regulations promulgated thereunder;
3. The renewal requested does not substantially jeopardize the permittee's continuing
responsibility on existing permit areas;
4. The operator has provided evidence that the performance bond in effect for the operation
will continue in full force for the proposed period of renewal as well as any additional
bond required;
5. Any additional revised or updated information as required has been provided.
Based on a preponderance of the evidence, the permit issued to Coors Energy Company meets the
requirements under the right of successive renewal.
The permit application will remain a binding part of the permit. Renewal of the permit will be for a
term of five(5)years.
I conclude that there is no basis for denying the renewal.

1. Introduction
This document is part of the decision package prepared by the Colorado Division of
Reclamation, Mining and Safety(the Division) for a permit renewal application (Application) of
Permit C-81-028. The Application was submitted by Coors Energy Company(CEC) for the
Keenesburg Strip Mine. This document includes: 1) the proposed decision to approve the
Application; 2) a summary which includes a history of the Application, a description of the
environment affected by the operation and a description of the mining and reclamation plan; and
3) the written findings of compliance the Division has made as required by the Colorado Surface
Coal Mining Reclamation Act. This Findings of Compliance document includes updated
information from the foregoing permit renewal Findings of 2006. Other sources of information
include the current version of the Permit Application Package, Annual Hydrologic Reports,
Annual Reclamation Reports, and other permit records, reports and findings.
Detailed information concerning the findings of compliance can be found in the Regulations of
the Colorado Mined Land Reclamation Board for Coal Mining.
Permit C-81-028 is for surface coal mining and reclamation operations. This Application is for
continuing reclamation work only, as all coal extraction operations have ceased. Reclamation
work includes the controlled disposal of ash and mine waste rock as a portion of the backfill of
mine pits. The mine will be operated by CEC. The mine is located on private lands within Weld
County, Colorado. The legal description of the lands included within the permit area is found in
the Index Maps and Legal Description section of the Permit Application Package (PAP).
1.1 Legal Description
The Permit Area consists of a tract of land in Sections 25 and 36, Township 3 North, Range 64
West of the 6th Principal Meridian, Weld County, Colorado, described as follows:

2. Proposed Decision
The Colorado Division of Reclamation, Mining and Safety proposes to approve this Application
for renewal of a valid existing permit. This decision is based on a finding that the operations will
comply with all requirements of the Colorado State Program as found in the Colorado Surface
Coal Mining Reclamation Act, Colorado Revised Statutes 34-33-101 et seq., and the Regulations
promulgated pursuant to the Act. If no request for a formal hearing is made within thirty(30)
days of the first publication of the issuance of this proposed decision, then this decision becomes
final. Acceptable surety has been submitted by the applicant. The Application, all supporting
documentation and any stipulations or conditions will become a binding part of the Permit.
3. Summary
3.1 The Review Process
3.1.1 Initiation of Renewal
The Division of Reclamation, Mining and Safety(Division) notified the Coors Energy Company
(CEC) on February 1, 2011 that the existing Permit for the Keenesburg Mine would expire on
November 3, 2011. CEC responded on April 21, 2011 with an application for permit renewal.
The Division deemed the Application complete on April 29, 2011.
3.1.2 Public Notice
Public notice of submittal of the Application was published four times in The Fort Lupton Press
between May 18, 2011 and June 8, 2011. Notice that the Application was considered complete
for the purposes of filing was provided by the Division, in accordance with Title 34, Article 33,
Section 118, Paragraph 3, of the Colorado Revised Statutes.
3.1.3 Application Reviews and Responses
The Application was reviewed for adequacy, and the Division identified nine items requiring
update or clarification in a letter to CEC (dated June 27, 2011). CEC provided acceptable
responses to all nine items in a submittal dated July 25, 2011.
3.1.4 Status of Permit Stipulations

3.1.8 Applicant Violator System
The Applicant Violator System (AVS) finding as of May 9, 2011 was "no violations." An AVS
finding of September 7, 2011 was "no violations." The Division recommendations for both of
these checks were "issue."
3.2 Description of the Environment
3.2.1 Maps
The Permit includes several maps. Three of these were revised in 2011 for TR-42:
• The Permit Area Map (Appendix A-1) shows the permit boundary and includes a legal
description of the site location.
• The Surface and Mineral Ownership Map (Appendix A-2) includes roads, sections, the
ownership boundary, and major drainages, including Ennis Draw to the east of the site.
• The Adjacent Property Owners Within One Mile map (Appendix A-3) is based on United
States Geological Survey(USGS) 7.5-minute Topographic Map Quadrangles Klug Ranch
and Tampa.
3.2.2 General, Disturbed and Affected Area
The Keenesburg Mine is located approximately 4.5 miles north of Keenesburg, Colorado. The
legal description of the permit area is presented under paragraph 1.1 above.
Per the RN-06 Application, there are 612.5 acres in the permit area, and approximately 438 acres
were disturbed. The Keenesburg Mine was a surface mine, and affected acreage equals the
disturbed acreage of approximately 438 acres. Of the 438 disturbed acres, approximately 251
acres have been reclaimed and revegetated, and approximately 165 acres have been Phase II
released (thus approximately 86 acres have been reclaimed and revegetated but not Phase III
released).
5
All of these acreages reflect the conditions of the site prior to the boundary change of'TR-42.
After TR-42 (which removed 57.1 acres from the permit area when it was finalized on July 5,
2011), the total acreage was reduced to 555.4 acres. The other values do not change, because the
area removed with TR-42 was all non-disturbed land or land that has been Phase III released.
3.2.3 Resource to be Mined
Currently, there is no coal extraction activity at the site and none is anticipated. The open pits are
being backfilled with mine waste rock and ash imported from the Trigen Colorado Steam and
Electric Plant in Golden, Colorado and reclaimed in accordance with the reclamation plan
described in the Permit. During active surface coal extraction, the Number 7 seam of the Laramie
formation was mined.
3.2.4 Geology, Soils and Topography
The permit area is located on level to gently rolling topography consisting of fine sand, which is
wind-deposited material overlying weathered residual shale. The sand varies in depth from about
5 feet to 20 feet, is highly to moderately permeable, and is highly susceptible to wind erosion.
The flat-lying number 7 coal seam is overlain by 60-180 feet of overburden consisting of yellow-
brown and gray to blue gray soft carbonaceous shale and clay interbedded with sand and shaley
sand. At the base of the Laramie formation is the Fox Hills member, a cross-bedded gray to buff
sandstone, which is slightly to well cemented.
3.2.5 Surface and Ground Water
Because of the low relief and deep, well-drained soils, there is virtually no surface runoff. No
streams, springs or seeps exist in the area. All water flows subsurface through aeolian deposits to
Ennis Draw, a topographic swale (ephemeral drainage) located along the eastern boundary of the
permit area. Ennis Draw appears to be a complex, braided, ancient stream bed that has been
covered by windblown sand. It discharges several miles to the north into Box Elder Creek.
Ground water moves laterally toward the northeast, and apparently discharges into the sands and
stream deposits in Ennis Draw.
At the time the mine was originally permitted, ground water in neither the coal nor overburden
was known to provide a water supply for any purpose in the vicinity of the mine. Since that time,
ground water is being drawn for industrial uses at the mine, and a number of other wells have
been drilled in the vicinity of the mine (review of State Engineer Records). However, no adverse
impact from the mine is expected, due to the geologic and hydrologic conditions of the site.
6
3.2.6 Climate
The Keenesburg mine site is situated in an area which has a"continental" type of climate,
characterized by low relative humidity, a large amount of sunshine, light rainfall, moderately
high winds, and large daily range in temperature. The average annual mean temperature is 48.4°
F. The annual average precipitation ranges from 11.12 to 16.32 inches. Fort Lupton, which has
an average annual precipitation of 12.5 inches, provides the best estimate of precipitation at the
area (Findings, 1992).
3.2.7 Vegetation, Wildlife and Land Use
The undisturbed lands in the area of the Permit are moderately to well stabilized by a sandsage-
prairie sandreed plant association that is used primarily for grazing by cattle in summer months.
Wildlife is limited to small rodents, primarily field mice, and birds with an occasional spotting of
raptors such as hawks or eagles. Deer and pronghorn are rare as are most higher order
vertebrates. CEC updated the evaluation of Threatened and Endangered species and habitat in
October 2006. There are no known threatened or endangered plants or animal species, nor
habitats for these species, in the area.
The premining land use classification of the area was rangeland, as shown on the general soil
map of Weld County(from the Soil Conservation Service and included in the Permit as page 37).
The post mining land use of the permit area is also rangeland. The land cannot support a variety
of uses under existing technologies and local resources. All attempts at dryland farming on the
area have been abandoned, and the damage caused by those attempts will remain evident for
many decades.
The premining soil capability class is VIe for irrigated and non-irrigated Valent soils. Osgood
soils have capability classes of IVe for irrigated crops and Vie for non-irrigated conditions.
3.3 Description of the Operation and Reclamation Plans
The Operation and Reclamation Plans are described in the PAP, Section 2.05.4, and some of the
important elements are described below.
3.3.1 Topsoil Stripping and Replacement Depths
No stripping of undisturbed topsoil is anticipated during the forthcoming renewal period of the
Permit. Only reclamation activities are anticipated. Replacement depths of topsoil are:
• Two feet over overburden spoil cover (on ash disposal areas)
• Two feet over roads
• Fifteen inches over the long-term spoil arca
7
• Six inches over facilities and topsand storage areas.
3.3.2 Revegetation Techniques
The approved revegetation plan emphasizes native species planting resulting in a diverse,
permanent, effective plant community capable of self-regeneration. The current seed mix is
included in Section 2.05.4 of the PAP (page 115).
Manure or organic mulch is to be spread on the topsand. The approved seed mix will be drill
seeded through the organic mulch. Small areas that require reseeding may be broadcast.
Two windows for seeding are March 15 to June 1 (spring) and September 15 to December 15
(fall).
A stubble mulch(such as sorghum) may be seeded in the spring or fall prior to seeding of the
permanent seed mix.
Hay/straw mulch, hydromulch and tackifier, soil amendments, and compost products may also be
used.
No irrigation is proposed.
The site is currently inspected at least quarterly for pests and diseases. No infestations of pests or
noxious weed species have been identified.
Grazing is prohibited during the first two years of vegetation establishment on reclaimed areas.
Grazing may be allowed thereafter. Grazing will not be allowed to interfere with vegetation
sampling for monitoring or bond release purposes, and eligible areas will not be grazed during
the growing season prior to sampling.
Revegetated areas that have experienced three or more growing seasons are monitored for
success standards of cover and production. Eligible areas are sampled in the last two consecutive
growing seasons prior to final bond release, but not earlier than years nine and ten of the
extended liability period.
3.3.3 Mining Techniques, Directions, Mine Life, Production Rates
No further extraction of coal is anticipated at the site. The estimated mine life is through year
2020.
3.3.4 Surface Handling of Coal (crush, screen, wash)
There is no surface handling of coal at the site, and none is anticipated.
8
3.3.5 Disposal of Waste
There are no coal processing wastes or mine development wastes on site, nor will any be
generated by current or anticipated future activities. There were, and will be, some reclamation
wastes (Non-Coal Wastes) generated by demolition of facilities. These wastes were and may be
placed in the pits between the limits of five feet above the local ground water table and four feet
below Approximate Original Contour(AOC). Ash (generated off-site at the Trigen power plant
in Golden) and mine waste rock is permitted for placement in Pits A (completed) and B. This
waste is placed five feet above the re-established local ground water table, and covered with six
feet of overburden spoil and two feet of topsand.
3.3.6 Other Reclamation
All facilities at the site are currently scheduled for removal, with the exception of electrical lines
not owned by CEC, the Permanent Dugout Pond, Permanent Sediment Pond 2, and associated
diversion/drainage ditches. Facilities to be demolished include the office, shop and warehouse;
the equipment parking lot; the sewage treatment facility; all roads; the electrical distribution
system (owned by CEC); the potable water system; the explosive storage facilities, and
monitoring wells (PAP, Section 2.05.3).
Pit highwalls will be graded into the pit backfill.
3.3.7 Water Rights and Usage
Two wells are permitted on the site(PAP, Section 2.03.10, page 31).

Findings of the Division of Reclamation, Mining and Safety
for the Keenesburg Strip Mine
September 7, 2011
Explanation of Findings
Pursuant to Rule 2.07.6(2) of the Regulations of the Colorado Mined Land Reclamation Board
for Coal Mining (Regulations), which was promulgated by the Colorado Surface Coal Mining
Reclamation Act (Act), the Division or the Board must make specific written findings prior to
permit renewal. These findings are based on information made available to the Division that
demonstrates that the applicant will be able to operate in compliance with the Act and
Regulations.
This findings document is updated upon permit renewal. The previous renewal for the
Keenesburg Strip Mine was for a 5 -ear permit term, and this findings document is in support of
an anticipated 5-year permit term. The following findings were reevaluated and updated where
necessary to reflect changes that have occurred during the past permit term. Any stipulations
from the original permit and findings document or from subsequent revisions that have been
resolved to the satisfaction of the Division have been removed from this document.
Section A- Rule 2.07.6
1. Accuracy and Completeness
The renewal application is accurate and complete. All requirements of the Act and Regulations
have been complied with [Rule 2.07.6(2)(a)].
2. Feasibility
Based on information contained in the Application and other information available to the
Division, the Division finds that surface coal mining was, and reclamation can be, feasibly
accomplished at the Keenesburg Strip Mine [Rule 2.07.6(2)(b)].
3. Assessment of Probable Cumulative Hydrologic Impacts
An assessment of the probable cumulative impacts of all anticipated coal mining in the general
area on the hydrologic balance has been made by the Division. This assessment, entitled
"Cumulative Hydrologic Impact Assessment Boulder/Weld Coal Field CHIS Coors-
Keenesburg," is available for inspection at the offices of the Division. The Division finds that the
operations proposed under the Application have been designed to prevent damage to the
hydrologic balance outside the proposed permit area. Please refer to Item V. of Section B of this
10
document for additional discussion of the predicted hydrologic consequences of mining
operations at the Keenesburg Strip Mine [Rule 2.07.6(2)(c)].
4. Relative Location
As required by Rule 2.07.6(2)(d), the Division finds that the affected area is (subject to valid
rights existing as of August 3, 1977) not within:
a) An area designated unsuitable for surface coal mining operations
b) An area under study for designation as unsuitable for surface coal mining
c) The boundaries of the National Park System, the National Wildlife Refuge
System, the National System of Trails, the National Wilderness Preservation
System, the Wild and Scenic Rivers System including rivers under study for
designation, and National Recreation Areas
d) Three hundred feet of any public building, school, church, community or
institutional building, or public park
e) One hundred feet of a cemetery
1) The boundaries of any National Forest
g) One hundred feet of the outside right-of-way line of any public road except where
mine access or haul roads join such line, and excepting any roads for which the
necessary approvals have been received, notices published, public hearing
opportunities provided, and written findings made
h) Three hundred feet of an occupied dwelling.
5. National Register of Historic Places and Public Parks
On the basis of information submitted by CEC in the form of a letter(written by Cultural
Resource Consultants, Inc., November 10, 1978, on file as Appendix E-I in the PAP), the
Division finds that subject to valid existing rights as of August 3, 1977, the mining operation will
not adversely affect any publicly owned park or place listed on, or eligible for listing in, the
National Register of Historic Places as determined by the State Historic Preservation Office
[Rule 2.07.6(2)(e)(i)].
6. Mineral and Surface Estates
For this surface mining operation, the private mineral estate has been severed from the private
surface estate. Therefore, the documentation specified by Rule 2.03.6(2) has been provided in
Section 2.03.6 of the PAP [Rule 2.07.6(2)(f)].
7. Compliance with Laws, Rules and Regulations
On the basis of evidence submitted by the applicant and received from other state and federal
agencies as a result of the Section 34-33-114(3) compliance review required by the Act, the
Division finds CEC does not own or control any operations that are currently in violation of any
law, rule, or regulation of the United States (including any provision of the Surface Mining
11
Control and Reclamation Act). Nor does CEC own or control any operations that are currently in
violation of any State law, rule, or regulation (including any provision of the Act) [Rule
2.07.6(2)(g)(i)]•
8. Determination of Willful Violations
Coors Energy Company does not control and has not controlled mining operations with a
demonstrated pattern of willful violations of the Act of such nature, duration, and with such
resulting irreparable damage to the environment as to indicate an intent not to comply with the
provisions of the Act [Rule 2.07.6(2)(h)].
9. Consistency with Adjacent Activities
The Division finds that surface coal mining and reclamation operations to be performed under
this permit will not be inconsistent with other such operations anticipated to be performed in
areas adjacent to the permit area [Rule 2.07.6(2)(i)].
10. Reclamation Liability
The Division estimated the remaining reclamation liability for mining operations to be
$1,913,161.94. The detailed cost estimate is included in this report as Appendix A. This is a
reduction from the previous estimate of$2,001,475.00 from September 2010. The reduction is
due to a change in the soil swell factor and increased equipment efficiency rates.
The Division currently holds a$2,001,475.00 performance bond for the Keenesburg Strip Mine,
which is sufficient to accomplish the remaining reclamation work at the site [Rule 2.07.6(2)(j)].
11. Prime Farmlands
The Division has made a negative determination for the presence of prime farmland within the
permit area. The decision was based on a letter from the Natural Resources Conservation Service
(formerly the SCS) dated May 29, 1981. This letter(included in the PAP, page 101) states that
no prime farmland mapping units are found within the permit area [Rule 2.07.6(2)(k)].
12. Alluvial Valley Floors
The Division has made a negative determination for the existence of alluvial valley floors within
the permit area. This determination is based on information provided by the applicant and
included in the PAP in Section 2.06.8 and in Appendixes 1-1 and 1-2 [Rules 2.07.6(2)(k) and
2.06.8(3)(c)].
12
13. Post-mining Land Use
The Division has approved the post-mining land use of the operation as Rangeland. It was
determined that a rangeland designation meets the requirements of Rule 4.16 for the permit area
[Rule 2.07.6(2)(1)].
14. Approvals
Specific approvals have been granted or are proposed. These approvals are addressed in Section
B below [Rule 2.07.6(2)(m)].
15. Threatened and Endangered Species
The Division finds that the current and proposed activities at the Keenesburg Strip Mine will not
affect the continued existence of endangered or threatened species or result in the destruction or
adverse modification of their critical habitats [Rule 2.07.6(2)(n)].
16. Reclamation Fees
The Division has contacted the Reclamation Fees Branch within the Office of Surface Mining
and determined that CEC is current in the payment of reclamation fees required by the Code of
Federal Regulations (30 CFR, Chapter VII, subchapter R) [Rule 2.07.6(2)(o)].
Section B - Rule 4
The PAP for the Keenesburg Mine does not have section names that correspond to Section 4 of
the Rules. However, the operations plan, found under Section 2.05.3 of the PAP, contains the
necessary information as discussed below.
I. Rule 4.01 General Provisions
The Division finds that performance standards and design requirements of the (renewed) permit
will provide for the scope and objectives of general provisions of Rule 4.01.
II. Rule 4.02 Signs and Markers
Signs and appropriate permit markers are erected and in place at the site. An entrance sign in
compliance with Rule 4.02 is in place, as are topsoil (topsand) pile signs.
13
III. Rule 4.03 Roads
Haul Roads
Hauling of coal, spoil, and coal mine waste has been terminated at the Keenesburg Mine, and
there are no plans to resume these activities. Haul roads at the site have been re-classified as
Access Roads [Rule 4.03.1].
Access Roads
Access roads have been designed, constructed, and certified by a registered professional engineer
[Rule 4.03-2(11(d)].
Light Use Roads
Light use roads have been designed and constructed in accordance with Rule 4.03.3(7). Some
light use roads are permitted to be left in support of approved post-mining land use.
IV. Rule 4.04 Support Facilities
No new support facilities are anticipated on the site. The construction of existing support
facilities has not damaged or caused disruption of any pipelines, railroads, or utility lines that
pass over, under, or through the permit area. The Division approved the existing facilities [Rule
4.04(6)].
Several gas wells have been installed within the permit area by a third party. The gas companies
maintain these well sites and access to the wells. These locations have been classified as
industrial land use. Reclamation of the well sites is the responsibility of the gas companies, and
this responsibility is stated in the contracts between them and CEC.
V. Rule 4.05 Hydrologic Balance
Water Quality Standards and Effluent Limitations
CEC has established drainage systems, including sediment ponds, to meet the applicable State
and Federal water quality requirements for downstream receiving waters [Rule 4.05.2]. These
rules include those of the Colorado Department of Public Health and Environment (CDPHE).
14
There is currently no surface water monitoring at the Keenesburg Mine Site, because there is no
point of surface water discharge. On December 18, 1989, Technical Revision 23 approved the
deactivation of the Colorado Discharge Permit System (CDPS) permit, and the Department of
Health (former name of CDPHE) concurred with this decision. Permit COG-850038 was later
reinstated with an expiration date of June 30, 1997. CEC again proposed, and CDPHE approved,
the expiration of the CDPS permit without renewal (the CDPHE letter regarding the Request for
Inactivation of this permit can be found in Division files).
The Division proposes to continue the approved exemption of certain small disturbed areas
(topsand storage and reference area sites) from the requirement to have runoff from the small
areas report to sediment ponds. This is because of the limited size of the areas, and that ponds
and treatment facilities are not necessary for drainage to meet the effluent limitations of Rule
4.05.2 and applicable State and Federal water quality standards for receiving streams. Mixing of
the surface drainage from these areas with a discharge from underground workings will not
occur. The small areas to be exempted are described in the Index Maps and Legal Description
sections of the Permit [Rule 4.05.2(3)(b)(i)].
Ground Water Monitoring Plan
The following ground water monitoring plan is required by Rule 4.05.130).
Monitoring Wells
The table below summarizes well information. Elevations are top of casing elevations.
Well Elev. Aquifer Location
FPW 4780 Ennis Draw Mine
DH96 4764 Ennis Draw Downstream from Mine
DH122 4814 Ennis Draw Upstream from Mine
SMW-2 4803 Reclaimed Spoil Mine
AMW-1 4804 Undisturbed Overburden Downstream of B Pit
AMW-2 4811 Reclaimed Spoil Downstream of A Pit
Well sampling and water levels of subsurface water are taken from Wells SMW-2, AMW-1,
FPW, DH96 and DH122. Wells are sampled quarterly.
The sampling parameters are:
• Calcium - dissolved
15
• Iron- dissolved
• Magnesium - dissolved
• Manganese - dissolved
• Molybdenum - dissolved
• Sodium - dissolved
• Selenium - dissolved
• Lead - dissolved
• Hardness (as CaC03)
• Alkalinity, total (as CaC03 to pH 4.5)
• Carbonate (as C03)
• Bicarbonate (as HC03)
• pH (pH units)
• Specific conductance (mmhos/cm)
• Chloride
• Hydroxide (as OH-)
• Sulfate (S04)
• Total dissolved solids (at 180 degrees C)
• SAR (sodium absorption ratio).
The Division will require the sealing of drilled holes. Each hole, well, or other underground
opening is to be capped, sealed, backfilled, or otherwise properly managed [Rule 4.07.3].
Diversions and Conveyance of Overland Flow
There are two approved permanent diversion ditches for the conveyance of overland flow from
disturbed areas to Permanent Sediment Pond 2.
There are no, and there is no requirement for, diversions on an existing landslide [Rule
4.05.3(5)].
Stream Channel Diversions
There are no, and there is no requirement for, stream channel diversions [Rules 4.05.4(1) and
(4)].
Sedimentation Ponds
Permanent Sedimentation Pond 2 is in compliance with Rule 4.05.6.
Acid-forming and Toxic-forming Spoil
No acid-forming or toxic-forming soils are known to exist on the site [Rule 4.05.8(3)].
16
Impoundments
A dugout pond exists on the site as a permanent impoundment. Permanent Sediment Pond 2 has
been approved as a permanent impoundment. Both the dugout pond and Permanent Sediment
Pond 2 have been approved as permanent in accordance with Rule 4.05.9(13). The sanitary
sewage treatment lagoon is an integral part of the sanitary sewage treatment system. The
treatment lagoon is to be removed under final reclamation.
Transfer of Wells
No transfer of wells is proposed in the Application [Rule 4.05.14 (2)].
Discharge of Water into an Underground Mine
There is no discharge of water into an underground mine at the site [Rule 4.05.16(2)].
Stream Buffer Zones
There are no, and there is no requirement for, stream buffer zones on the site [Rule 4.05.18(1)].
Probable Hydrologic Consequences
Probable hydrologic consequences are presented in the Water Resources and Impact Evaluation
Report, Appendix I of the PAP, as well as the Annual Hydrology Reports. It is the Division's
opinion that mining and reclamation activities at the Keenesburg Strip Mine have had no
appreciable effect on the hydrologic balance of the area, and future activities will not
significantly impact the hydrologic balance.
VI. Rule 4.06 Topsoil
The mine operated in compliance with the general requirements (Rule 4.06.1), removal (Rule
4.06.2), and storage (Rule 4.06.3) of topsoil. No additional stripping operations of undisturbed
topsand (topsoil) are anticipated. CEC proposes to continue reclamation activities in compliance
with redistribution requirements [Rule 4.06.4].
VII. Rule 4.07 Sealing of Drilled Holes and Underground Openings
All former drill holes at the mine site have been changed to ground water monitoring sites, mined
through, or permanently plugged. CEC plans to continue to comply with the requirement of Rule
4.07 in regards to the sealing of drilled holes.
17
VIII. Rule 4.08 Use of Explosives
Explosives (for mining) are no longer used on the site. Any use of explosives in demolition of
facilities would be procured by contract.
IX. Rule 4.09 Disposal of Excess Spoil
All spoil is proposed for redistribution over disturbed areas [Rule 4.09.1(1)].
X. Rule 4.10 Coal Mine Waste Banks
There are no coal mine waste banks on the site. No coal mine waste is anticipated to be generated
as the site is in the reclamation phase [Rule 4.10.1(1)].
XI. Rule 4.11 Coal Mine Waste
There is no coal processing waste or underground development waste generated, and none is
anticipated, at the site. Thus the disposal of coal mine waste is not applicable to the permit.
XII. Rule 4.12 Slides and Other Damage
No slides or other damage have been recorded at the site.
XIII. Rule 4.13 Contemporaneous Reclamation
Variances to contemporaneous reclamation were granted during mining operations for the
backfilling and grading of Pit A (completed) and Pit B and for the current backfilling operations.
The Backfilling and Grading section below describes this in more detail.
XIV. Rule 4.14 Backfilling and Grading
CEC requested additional time for backfilling and grading following coal removal from the
contour strip mine. A detailed written analysis provided by CEC in accordance with Section
2.05.4(2)(c) has demonstrated that additional time was necessary. Therefore, the Division
approved the additional time [Rule 4.14.1(1)]. A variance was granted on February 28, 1989 to
allow for use of the A and B pits as ash and mine waste rock disposal sites (Technical Revision
20). Disposal is anticipated to last until 2020 (PAP, Section 2.05.3,page 117).
The Division approved a minor modification of the general requirements of Rule 4.14.2 for
reclamation of Pits A and B to approximate original contour to accommodate the disposal of ash
and mine waste rock(PAP, Section 2.05.4, page 113). Slopes are slightly steeper to reduce
infiltration to the buried ash.
18
XV. Rule 4.15 Revegetation
The approved revegetation plan (starting on page 115 of the PAP) emphasizes native species as
illustrated in the seed mix on page 115.
A sorghum mulch was approved as an optional means to meet soil stabilization requirements
until vegetation is re-established [Rule 4.15.4].
Approved methods to measure herbaceous cover, production, and species diversity are discussed
in the PAP, Section 2.04.10. Techniques include selection of sample locations using randomly-
generated grid coordinates and random determination of transect directions. A stationary optical
sighting device is used to determine hits. Reclamation success for vegetative cover is determined
using an approved formula which accounts for effective precipitation. Reclamation success for
herbaceous productivity is determined using an approved formula which accounts for effective
precipitation. These formulae for reclamation success were derived from data collected on the
Osgood reference area over a ten-year period. The Osgood reference area itself is no longer
needed for comparison upon approval of TR37 (PAP, Section 2.05.4, page 116b). The
reclamation success criteria for species composition are:
• A minimum of four perennial species
• A minimum of three warm season perennial grass species
• For each species, a relative importance of no more than 40 percent or less than
three percent.
For this permit, there is no minimum density(stems/acre) standard for woody plant
reestablishment.
XVI. Rule 4.16 Post-mining Land Use
The post-mining land use of rangeland meets the criteria of Rule 4.16.3. The site is classified as
rangeland by the U.S. Department of Agriculture, Natural Resources Conservation Service, as
shown on the general soil map of Weld County, Colorado (page 37 of the PAP). In addition,
several gas wells have been installed within the permit area by a third party. These locations
have been classified as industrial land use.
The proposed postmining land use is compatible with adjacent land use. Demonstrations of
feasibility are not necessary. The proposed use will not present actual or probable hazard to
public health or safety nor pose actual or probable threat of water flow diminution on pollution.
The use will not involve unreasonable delays in reclamation. No measures to prevent or mitigate
adverse effects on fish, wildlife, and related environmental values or threatened or endangered
plants are necessary(PAP, Section 2.05.6 (2)).
19
XVII. Rule 4.17 Air Resource Protection
The Colorado Department of Public Health and Environment (CDPHE) administers emission
permits. However, air emission permits for the Keenesburg Strip Mine have been canceled, and
reclamation activities were re-designated to Air Pollution Emission Notice (APEN) required
status.
XVIII.Rule 4.18 Protection of Fish, Wildlife and Related Environmental Values
There are no fish, and there is no fish habitat, on the site. Impacts to as many as 50 species of
mammals, birds, and reptiles are described in the permit, as well as their recovery after
reclamation (PAP, Section 2.04.11). There are no known endangered species in the area.
XIX. Rule 4.19 Protection of Underground Mining
There were no underground mining activities at the site, and none are planned [Rules 4.19(1) and
4.22.4(1)].
XX. Rule 4.20 Subsidence Control
No potential for subsidence exists at the site, thus no control plan is required.
XXI. Rule 4.21 Coal Exploration
There is no longer any coal exploration on site.
XXII. Rule 4.22 Concurrent Surface and Underground Mining
There has never been underground mining at the site. Furthermore, all mining has ceased at the
site, and there are no plans to re-initiate mining.
XXIII.Rule 4.23 Auger Mining
There was no auger mining at the site, and none is planned.
XXIV.Rule 4.24 Operations in Alluvial Valley Floors
The Division concurred that there is no alluvial valley floor on the site (PAP, Section 2.06.8,
page 130).
XXV. Rule 4.25 Operations on Prime Farmland
The Division concurred that there is no prime farmland within the permit boundary (PAP,
Section 2.04.12, page 100).
20
XXVI.Rule 4.26 Mountaintop Removal
No mountaintop removal operations are associated with the site.
XXVII. Rule 4.27 Operations on Steep Slopes
No operations on steep slopes are associated with the site.
XXVIII. Rule 4.28 External Plants and Facilities
There are no coal processing plants and support facilities located beyond the permit area for the
mine that are associated with the permitted activity.
XXIX. Rule 4.29 In Situ Processing
No in-situ processing was or is planned for the site.
XXX. Rule 4.30 Cessation of Operations
Coal extraction has ceased at this mine. Reclamation activities are proposed to occur through the
next five-year term.
