Introduction
This appendix discusses the leasing stipulations as
they will be applied to BLM managed lands in the planning
area. Operating standards pertinent to the locatable and
salable minerals program are also described. Mineral
exploration and development on federal lands must also
comply with laws and regulations administered by several
agencies of the State of Oregon; however, these specific
requirements are not discussed in this document.
Stipulations and operating standards pertaining to the
No Action Alternative, Alternatives A through E, and the
Preferred Alternative can be found in the Draft Resource
Management Plan and Environmental Impact Statement.
Leasable Mineral Resources
Oil and Gas Leasing
The Mineral Leasing Act of 1920 (as amended) provides
that all publicly-owned oil and gas resources be open to
leasing unless a specific land order has been issued to
close the area. Through the land use planning process,
the availability of these resources for leasing is
analyzed, taking into consideration development potential
and surface resources. Restrictions on oil and gas
operations are identified and placed in the leases as
notices and stipulations. Oil and gas leases are then
issued from the BLM Oregon State Office in Portland. A
leasing notice, and specific lease stipulations, for the
Proposed Resource Management Plan are listed later in
this appendix.
The issuance of a lease conveys to the lessee an
authorization to actively explore and/or develop the
lease, in accordance with the attached stipulations and
the standard terms outlined in the Federal Onshore Oil
and Gas Leasing Reform Act. Restrictions on oil and gas
activities in the planning area will take the form of
timing limitations, controlled surface use, or no surface
occupancy stipulations used at the discretion of the
Authorized Officer to protect identified surface
resources of special concern.
Stipulations will be attached to each lease before it
is offered for sale by the field office which reviews the
lease tract. The review will be conducted by consulting
the direction given in this proposed resource management
plan. In addition, all lands administered by BLM within
the planning area will be subject to the lease notice as
shown on the following pages. Every attempt will be made
to place stipulations in the lease and to minimize use of
Standard Conditions of Approval attached to the site
specific permit. All federal lessees or operators are
required to follow procedures set forth by: Onshore Oil
and Gas Orders, Notices to Lessees, The Federal Oil and
Gas Royalty Management Act (as amended), The Federal
Onshore Oil and Gas Leasing Reform Act and Title 43 Code
of Federal Regulations, Part 3100.
Oil and Gas Operations
Geophysical Exploration
Geophysical operations may be conducted regardless of
whether the land is leased or not. Notices to conduct
geophysical operations on BLM surface are received by the
resource area. Administration and surface protection are
accomplished through close cooperation of the operator
and the BLM. Seasonal restrictions may be imposed to
reduce fire hazards, conflicts with wildlife, watershed
damage, etc. An operator is required to file a
"Notice of Intent to Conduct Oil and Gas Exploration
Operations" for all geophysical activities on public
land administered by BLM. The notice should adequately
show the location and access routes, anticipated surface
damages, and time frame. The operator is required to
comply with written instructions and orders given by the
Authorized Officer, and must be bonded. Signing of the
Notice of Intent by the operator signifies agreement to
comply with the terms and conditions of the notice,
regulations, and other requirements prescribed by the
Authorized Officer. A pre-work conference and/or site
inspection may be required. Periodic checks during and
upon completion of the operations will be conducted to
ensure compliance with the terms of Notice of Intent,
including reclamation.
Drilling Permit Process
The federal lessee or operating company selects a
drill site based on spacing requirements, subsurface and
surface geology, geophysics, topography, and economic
considerations. Well spacing is determined by the
authorized officer after considering topography,
reservoir characteristics, protection of correlative
rights, potential for well interference, interference
with multiple use of lands, and protection of the surface
and subsurface environments. Close coordination with the
State will take place. Written field spacing orders are
issued for each field. Exceptions to spacing requirements
involving federal lands may be granted after joint State
and BLM review.
Notice of Staking
Once the company makes the decision to drill, they
must decide whether to submit a Notice of Staking or
apply directly for a permit to drill. The Notice of
Staking is an outline of what the company intends to do,
including a location map and sketched site plan. The
Notice of Staking is used to review any conflicts with
known critical resource values and to identify the need
for associated rights-of-way and special use permits. The
BLM utilizes information contained in the Notice of
Staking and obtained from the on-site inspection to
develop conditions of approval to be incorporated into
the application for permit to drill. Upon receipt of the
Notice of Staking, the BLM posts the document and
pertinent information about the proposed well in the
District Office for a minimum of 30 days prior to
approval, for review and comment by the public.
Application for Permit to Drill
The operator may or may not choose to submit a Notice
of Staking; in either case, an Application for Permit to
Drill must be submitted prior to drilling. An application
for permit to drill consists of two main parts; a 12
point surface plan which describes any surface
disturbances and is reviewed by resource specialists for
adequacy with regard to lease stipulations designed to
mitigate impacts to identified resource conflicts with
the specific proposal, and an 8 point subsurface plan
which details the drilling program and is reviewed by the
staff petroleum engineer and/or geologist. This plan
includes provisions for casing, cementing, well control,
and other safety requirements. For the application for
permit to drill option, the on-site inspection is used to
assess possible impacts, and develop stipulations to
minimize these impacts. If the Notice of Staking option
is not utilized, the 30 day posting period begins with
the filing of the application for permit to drill.
Private surface owner input is actively solicited during
the application for permit to drill stage.
Geothermal Leasing
The Geothermal Steam Act of 1970 (as amended) provides
for the issuance of leases for the development and
utilization of geothermal steam and associated geothermal
resources. Geothermal leasing and operational regulations
are contained in Title 43 Code of Federal Regulations,
Part 3200. Through the land use planning process the
availability of the geothermal resources for leasing is
analyzed, taking into consideration development potential
and surface and subsurface resources. Restrictions on
geothermal operations are identified and placed in the
leases as stipulations. Geothermal leases are then issued
by the BLM Oregon State Office in Portland.
Geothermal resources within a known geothermal
resource area are offered by competitive sale. Outside of
known geothermal resource areas, leases can be issued
non-competitively (over-the-counter). Prior to a
competitive lease sale, or the issuance of a
non-competitive lease, each tract will be reviewed, and
appropriate lease stipulations will be included. The
review will be conducted by consulting the direction
given in this resource management plan. The issuance of a
lease conveys to the lessee authorization to actively
explore and/or develop the lease in accordance with
regulations and lease terms and attached stipulations.
Subsequent lease operations must be conducted in
accordance with the regulations, Geothermal Resources
Operational Orders, and any Conditions of Approval
developed as a result of site-specific National
Environmental Policy Act analysis. In the planning area,
restrictions in some areas will include timing
limitations, controlled surface use, or no surface
occupancy stipulations used at the discretion of the
Authorized Officer to protect identified surface
resources of special concern.
In addition to restrictions related to the protection
of surface resources, the various stipulations and
conditions could contain requirements related to
protection of subsurface resources. These may involve
drainage protection of geothermal zones, protection of
aquifers from contamination, or assumption of
responsibility for any unplugged wells on the lease.
Development of geothermal resources can be done only
on approved leases. Orderly development of a geothermal
resource from exploration to production involves several
major phases that must be approved separately. Each phase
must undergo the appropriate level of National
Environmental Policy Act compliance before it is approved
and subsequent authorization(s) are issued.
Leasing Notice and Stipulation Summary
On the following pages, the mineral leasing notice and
stipulations for the Proposed Resource Management Plan
are shown. In addition to the notice and stipulations,
the standard leasing terms (Form 3100-11) will be used.
The powersite stipulation (Form 3730-1) will be used on
lands within powersite reservations.
Stipulations also can include waivers, exceptions, and
modifications. Stipulations that involve an issue of
major concern can be waived, excepted, or modified only
with at least a 30-day public review (43 CFR 3101.1-4).
Waiver, exception, and modification are defined as
follows:
- Waiver - The lifting of a stipulation from a
lease which constitutes a permanent revocation of
the stipulation from that time forward.
- Exception - This is a one time lifting of the
stipulation to allow a permitting activity for a
specific proposal. This is a case-by-case
exemption. The stipulation continues to apply to
all other sites within the leasehold to which the
restrictive criteria apply.
- Modification - This is a either a temporary or
permanent change to the provisions of a lease
stipulation. A modification may, therefore,
include an exemption from or alteration to a
stipulated requirement. Depending on the specific
modification, the stipulation may or may not
apply to all other sites within the leasehold to
which the restrictive criteria apply.
Throughout the alternatives, the no surface occupancy
stipulation is used rather than not leasing, because
leasable minerals, if present, can be produced from most,
if not all of each of the parcels that are subject to
this stipulation without impacting the value(s) needing
protection.
Whenever a special stipulation, such as no surface
occupancy, timing, controlled surface use, or special
status species is used, the need for the special
stipulation is described in the objective that follows
the stipulation. By imposing these special stipulations,
it has been concluded that less restrictive stipulations
would not be adequate to meet the stated objective.
Lease notices are attached to leases in the same
manner as stipulations; however, there is an important
distinction between lease notices and stipulations. Lease
notices do not involve new restrictions or requirements.
Any requirements contained in a lease notice must be
fully supported by laws, regulations, policies, onshore
oil and gas orders, or geothermal resources operational
orders.
Leasing Notice and Stipulations for the Proposed
Resource Management Plan
Leasing Notice (for all leases)
Cultural Resources: An inventory of the leased lands
may be required prior to surface disturbance to determine
if cultural resources are present and to identify needed
mitigation measures. Prior to undertaking any
surface-disturbing activities on the lands covered by
this lease, the lessee or operator shall:
- Contact the Bureau of Land Management (BLM) to
determine if a cultural resource inventory is
required. If an inventory is required, then;
- The BLM will complete the required inventory; or
the lessee or operator, at their option, may
engage the services of a cultural resource
consultant acceptable to the BLM to conduct a
cultural resource inventory of the area of
proposed surface disturbance. The operator may
elect to inventory an area larger than the
standard ten-acre minimum to cover possible site
relocation which may result from environmental or
other considerations. An acceptable inventory
report is to be submitted to the BLM for review
and approval no later than that time when an
otherwise complete application for approval of
drilling or subsequent surface-disturbing
operation is submitted.
- Implement mitigation measures required by the
BLM. Mitigation may include the relocation of
proposed lease-related activities or other
protective measures such as data recovery and
extensive recordation. Where impacts to cultural
resources cannot be mitigated to the satisfaction
of the BLM, surface occupancy on that area must
be prohibited. The lessee or operator shall
immediately bring to the attention of the BLM,
any cultural resources discovered as a result of
approved operations under this lease, and shall
not disturb such discoveries until directed to
proceed by the BLM.
Authorities: Compliance with Section 106 of the
National Historic Preservation Act is required for all
actions which may affect cultural properties eligible to
the National Register of Historic Places. Also,
compliance with the Archaeological Resources Protection
Act and the Native American Graves Protection Act is
required. Section 6 of the Oil and Gas Lease Terms (Form
3100-11) requires that operations be conducted in a
manner that minimizes adverse impacts to cultural and
other resources.
Leasing Stipulations
Standard Leasing Terms
Standard leasing terms for oil and gas are listed in
Section 6 of Offer to Lease and Lease for Oil and Gas,
Form 310011. They are:
Lessee shall conduct operations in a manner that
minimizes adverse impacts to the land, air and water, to
cultural, biological, visual and other resources, and to
other land uses or users. Lessee shall take reasonable
measures deemed necessary by lessor to accomplish the
intent of this section. To the extent consistent with
lease rights granted, such measures may include, but are
not limited to, modification to siting or design of
facilities, timing of operations, and specification of
interim and final reclamation measures. Lessor reserves
the right to continue existing uses and to authorize
future uses upon or in the leased lands, including the
approval of easements or rightsofway. Such uses shall be
conditioned so as to prevent unnecessary or unreasonable
interference with rights of lessee.
Prior to disturbing the surface of the leased lands,
lessee shall contact BLM to be apprised of procedures to
be followed and modifications or reclamation measures
that may be necessary. Areas to be disturbed may require
inventories or special studies to determine the extent of
impacts to other resources. Lessee may be required to
complete minor inventories or shortterm special studies
under guidelines provided by lessor. If in the conduct of
operations, threatened or endangered species, objects of
historic or scientific interest, or substantial
unanticipated environmental effects are observed, lessee
shall immediately contact lessor. Lessee shall cease any
operations that would result in the destruction of such
species or objects until appropriate steps have been
taken to protect the site or recover the resources as
determined by BLM in consultation with other appropriate
agencies.
Standard terms for geothermal leasing can be found on
Offer to Lease and Lease for Geothermal Resources (Form
3200-24), Section 6, and are very similar to those
described above for oil and gas leasing.
Powersite Stipulation (Form No. 3730-1) (to be
used on all lands
within powersite reservations.)
Special Leasing Stipulations
The following special stipulations are to be utilized
on specifically designated tracts of land as described
below:
Special Status Species (to be attached to all
leases)
Resources: Botany and Wildlife
Stipulation: Lands within this lease may be within the
suitable habitat of the Federal Threatened, Endangered or
Proposed Threatened and Proposed Endangered species,
either officially listed or proposed for listing as
Threatened or Endangered species. These species are
listed on Tables 3-22 and 3-23. If it is determined
through an environmental review process that these
species or their habitat exist within this lease, all
future operations will be analyzed and subjected to a
U.S. Fish and Wildlife Service or National Marine
Fisheries Service Section 7 consultation or conference to
ensure the action is not likely to jeopardize the
continued existence of the species or result in the
destruction or adverse modification of critical habitat.
Lands within this lease may bear some or all of the
species listed on Tables 3-22 and 3-23 which have
protected status as State Threatened; State Endangered;
Federal Candidate; Bureau Sensitive or are within the
suitable habitat of these species. These species are
protected by BLM policy as described in Manual 6840. All
future post-lease operations must be analyzed, utilizing
recent field data collected at the proper time of year,
to identify the presence of such species. If the field
examination indicates that the proposed activity may
adversely impact Federal candidate species, technical
assistance will be obtained from the Fish and Wildlife
Service to insure that the actions will not contribute to
the need to list a Federal Candidate as a Federal
Threatened or Endangered species. Technical assistance
may be obtained from the Fish and Wildlife Service or the
National Marine Fisheries Service to ensure that actions
will not contribute to the need to list a State
threatened, State endangered, or Bureau Sensitive species
as a Federal Threatened or Endangered species.
Therefore, prior to any surface disturbing activities
or even the use of vehicles off existing roads on this
lease, BLM approval is required. This restriction also
applies to geophysical activities for which a permit is
required. The approval is contingent upon the results of
site-specific inventories for any of the above mentioned
species. The timing of these inventories is critical.
They must be conducted at a time of year appropriate to
determine the presence of the species or its habitat. The
lessee is hereby notified that the process may take
longer than the normal 30 days and that surface activity
approvals may be delayed.
If no Federal threatened, Federal endangered, Proposed
threatened, or Proposed endangered species, or suitable
habitat for such species, are found during the
inventories, then no formal Section 7 consultation with
the Fish and Wildlife Service or the National Marine
Fisheries Service will be necessary, and the action will
be processed using the procedures found in the applicable
Oil and Gas Onshore Orders or Geothermal Resources
Operational Orders. However, the lessee is hereby
notified that, if any Federal threatened, Federal
endangered, Proposed threatened, Proposed endangered,
State threatened, State endangered, Federal candidate, or
Bureau sensitive species are found during the
inventories, or if the actions are proposed in designated
or proposed critical habitat, then surface disturbing
activities may be prohibited on portions of, or even all
of the lease, unless an alternative is available that
meets all of the following criteria: (a) The proposed
action is not likely to jeopardize the continued
existence of a threatened or endangered species; (b) The
proposed action is not likely to destroy or adversely
modify critical habitat for a threatened or endangered
species; (c) The proposed action is consistent with the
recovery needs in approved Fish and Wildlife Service or
National Marine Fisheries Service recovery plans or BLM
Habitat Management Plans for the threatened or endangered
species; and (d) The proposed action will not contribute
to the need to list species as Federal Threatened or
Endangered.
Objective: To protect officially listed or proposed
threatened or endangered plant or wildlife species; and
to ensure that post leasing oil and gas or geothermal
operations will not likely contribute to the need to list
other special status species as threatened or endangered.
Exception: An exception may be granted by the
Authorized Officer if it is determined that portions of
the area do not have any officially listed or proposed
threatened or endangered species, Federal Candidate,
State Threatened or Endangered species, or Bureau
Sensitive species, or their habitat.
Waiver: This stipulation may be waived if the species
is declared recovered and is no longer protected under
the Endangered Species Act, or if other species found
within the lease are no longer considered to be in the
Federal Candidate, State Threatened or Endangered, or
Bureau Sensitive categories.

Locatable Minerals Surface Management in the
Lakeview District
The following operational guidelines for mining
activities have been compiled to assist the miner in
complying with the 43 Code of Federal Regulations 3809,
which apply to all mining operations on BLM administered
lands. The manner in which the necessary work is to be
done will be site specific and all of the following
standards may not apply to each mining operation. It is
the mining claimant's and operator's responsibility to
avoid "unnecessary or undue degradation" and
they must perform all necessary reclamation work. Refer
to 43 Code of Federal Regulations 3809 for general
requirements. The BLM will provide site specific
guidelines for some mining proposals.
Construction and Mining
Vegetation Removal
Remove only that vegetation which is in the way of
mining activities. On Oregon and California land
merchantable timber must be marked by BLM prior to
cutting, and may not be used for firewood. The same
requirement is recommended for public land. It is
recommended that small trees (less than 6 inches diameter
at breast height) and shrubs are to be lopped and
scattered, or shredded for use as mulch. Trees over 12
inches diameter at breast height should be bucked and
stacked in an accessible location unless they are needed
for the mining operation.
Firewood
Firewood may not be cut and sold, or used off of the
mining claims.
Topsoil
All excavations should have all productive topsoil
(usually the top 12 to 18 inches) first stripped,
stockpiled and protected from erosion for use in future
reclamation. This also includes removal of topsoil before
the establishment of mining waste dumps and tailings
ponds if the waste material will be left in place during
reclamation.
Roads
Existing roads and trails should be used as much as
possible. Temporary roads are to be constructed to a
minimum width and with minimum cuts and fills. All roads
shall be constructed so as not to negatively impact slope
stability.
Water Quality
When mining will be in or near bodies of water, or
sediment will be discharged, contact the Department of
Environmental Quality. It is the operator's
responsibility to obtain any needed suction dredging,
stream bed alteration, or water discharge permits
required by the Department of Environmental Quality or
other state agencies. Copies of such permits shall be
provided to the Area Manager if a Notice or Plan of
Operations is filed.
Claim Monuments
Due to the history of small wildlife deaths, plastic
pipe is no longer allowed for lode claim staking pursuant
to state law. It is recommended that existing plastic
pipe monuments have all openings permanently closed. Upon
loss or abandonment of the claim, all plastic pipe must
be removed from the public lands, and when old markers
are replaced during normal claim maintenance, they are to
be either wood posts or stone or earth mounds, consistent
with state law.
Drill Sites
Exploratory drill sites should be located next to or
on existing roads when possible without blocking public
access. When drill sites must be constructed, the size of
the disturbance shall be as small as possible in order to
conduct drilling operations.
Dust and Erosion Control
While in operation, and during periods of temporary
shut-down, exposed ground surfaces susceptible to erosion
will need to be protected. This can be accomplished with
seeding, mulching, installation of water diversions, and
routine watering of dust producing surfaces.
Fire Safety
All State fire regulations must be followed, including
obtaining a campfire permit or blasting permit if needed.
All internal combustion engines must be equipped with
approved spark arresters.
Safety and Public Exclusion
The general public may not be excluded from the mining
claim. In the interest of safety, the general public can
be restricted only from specific dangerous areas
(underground mines, open pits or heavy equipment) by
erecting fences, gates and warning signs. It is the
operator's responsibility to protect the public from
mining hazards. Gates or road blocks may be installed on
existing or proposed roads only with the approval of the
Area Manager.
Occupancy
All structures/trailers on mining claims must be used
for mining purposes (must be reasonably incident to
mining) and should be covered by a notice or plan of
operation. Use of such a structure for residential
purposes not related to mining or for recreation is not
authorized.
Suction Dredging
Filing either Notice or Plan of Operations is required
for any suction dredge operation where the dredge is
equipped with a suction intake hose diameter of greater
than four inches, and for all suction dredge operations
involving more than one dredge regardless of size. The
operator must have the applicable Department of
Environmental Quality suction dredge permit prior to
starting work, and a copy should be submitted to the Area
Manager.
Tailings Ponds
Settling ponds must be used to contain fines and any
discharge into creeks must meet the Department of
Environmental Quality standards.
Trash & Garbage
Trash, garbage, used oil, etc. must be removed from
public land and disposed of properly. Do not bury any
trash, garbage or hazardous wastes on public lands.
Accumulations of trash, debris, or inoperable equipment
on public lands is viewed as unnecessary degradation and
will not be tolerated.
Cultural and Paleontological Resources
Operators shall not knowingly alter, injure, or
destroy any scientifically important paleontological
(fossil) remains or any historical or archaeological
site, structure, or object on federal lands. The operator
shall immediately bring to the attention of the Area
Manager, any paleontological (fossil) remains or any
historical or archaeological site, structure, or object
that might be altered or destroyed by exploration or
mining operations, and shall leave such discovery intact
until told to proceed by the Area Manager. The Area
Manager shall evaluate the discovery, take action to
protect or remove the resource, and allow operations to
proceed within 10 working days.
Threatened and Endangered Species of Plants/Animals
Operators shall take such action as may be needed to
prevent adverse impacts to threatened or endangered
species of plants and animals and their habitat which may
be affected by operations. Special status species
(federal candidate/Bureau sensitive) of plants and
animals, and their habitat, will be identified by the
Area Manager, and shall be avoided wherever possible.
Reclamation
Reclamation of all disturbed areas must be performed
concurrently with mining , or as soon as possible after
mining permanently ceases. Reclamation shall include, but
shall not be limited to: 1) saving of topsoil for final
application after reshaping of disturbed areas has been
completed; 2) measures to control erosion, landslides,
and water runoff; 3) measures to isolate, remove, or
control toxic materials; 4) reshaping the area disturbed,
application of topsoil, and revegetation of disturbed
areas, where reasonably practicable; and 5)
rehabilitation of fisheries and wildlife habitat. When
reclamation of the disturbed area has been completed,
except to the extent necessary to preserve evidence of
mineralization, the Area Manager must be notified so that
inspection of the area can be made.
Equipment and Debris
All mining equipment, vehicles, structures, debris and
trash must be removed from the public lands during
periods of non-operation and/or at the conclusion of
mining, unless authorization from the Area Manager is
given to the operator or claimant in writing.
Backfilling & Recontouring
The first steps in reclaiming a disturbed site are
backfilling excavations and reducing high walls. Coarse
rock material should be replaced first, followed by
medium sized material, with fine materials to be placed
on top. Recontouring means shaping the disturbed area so
that it will blend in with the surrounding lands and
minimize the possibility of erosion.
Seedbed Preparation
Recontouring should include preparation of an adequate
seedbed. This is accomplished by ripping or disking
compacted soils to a depth of at least six inches in
rocky areas and at least twelve inches in less rocky
areas. This should be done following the contour of the
land to limit erosion. All stockpiled settling pond
fines, and then topsoil, are spread evenly over the
disturbed areas.
Fertilizer
The Area Manager must be contacted to determine if
fertilization will be necessary, and if so, the type and
rate of application.
Revegetation
An Area Manager-approved revegetation prescription
must be used to provide adequate revegetation for erosion
control, wildlife habitat, and productive secondary uses
of public lands.
Mulch
As directed by the Area Manager, during review of the
Notice or Plan of Operations, the disturbed area may
require mulching during interim or final reclamation
procedures. Depending on site conditions, the mulch may
need to be punched, netted, or blown on with a tackifier
to hold it in place. In some cases, erosion control
blankets may be cost effective for use.
Roads
After mining is completed, all new roads shall be
reclaimed, unless otherwise specified by the Area
Manager. High wall and cutbanks are to be knocked down or
backfilled to blend with the surrounding landscape.
Remove all culverts from drainage crossings and cut back
the fill to the original channel. The roadbed should be
ripped to a minimum depth of twelve inches to reduce
compaction and provide a good seedbed. The road must then
be fertilized and seeded if necessary. When necessary,
waterbars are to be used to block access and provide
drainage.
Tailings Ponds
The ponds should be allowed to dry out and the fines
removed and spread with the topsoil, unless the fines
contain toxic materials. If the ponds contain toxic
materials, a plan will be developed to identify, dispose,
and mitigate effects of the toxic materials. If
necessary, a monitoring plan will also be implemented.
The ponds should then be backfilled and reclaimed.
Guidelines for Development of Salable Mineral
Resources in the Lakeview District
Proposed Operations
All proposed pits and quarries, and any exploration
that involves surface disturbance, are required to have
operating and reclamation plans that must be approved by
the Area Manager. All proposals will undergo the
appropriate level of review and compliance with the
National Environmental Policy Act.
Operating Procedures
Where practicable, the following requirements should
be made a part of every contract or permit providing for
the use of mineral material sites on the district:
- Oversized boulders shall not be wasted but shall
be broken and utilized concurrently with the
excavated material.
- The operator shall comply with local and state
safety codes covering quarry operations, warning
signs and traffic control. All necessary permits
must be obtained from state and county agencies.
- Use of the site for equipment storage and
stockpiling rock material is allowed for the
duration of the contract or permit. Use of the
site beyond that time would be authorized under a
special use permit.
- All topsoil shall be stockpiled or windrowed, as
appropriate, for use in reclamation.
- Prior to abandonment, all material sites will be
graded to conform with the surrounding
topography. Oversize material that is not usable,
and reject, will be placed in the bottom of the
pit, graded, and the pit floor and cutslopes
covered with topsoil. Reseeding, if necessary,
will be done as prescribed by the Area Manager.
Access roads no longer needed by the BLM will be
abandoned and reclaimed as directed by the Area
Manager.
Quarry Design
Where in steep terrain in the operating area, quarry
developments will require a series of benches to
effectively maximize the amount of mineral materials to
be removed in a safe manner. In most cases, bench height
should not exceed forty feet, and if the bench will be
used by bulldozers to access other parts of the quarry,
the width of the bench should be at least twenty-five
feet. If the bench is not used by equipment, then this
width can be reduced to approximately ten feet.
Clearing of timber and brush should be planned at
least ten feet beyond the edge of the excavation limit.
Most often the brush will be piled and burned at the
site, or scattered nearby.
If at all possible, all topsoil and overburden should
be stockpiled and saved for eventual quarry site
reclamation. These piles may need to be stabilized by
seeding in order to minimize erosion during the winter
months.
As a standard procedure, the excavation of the quarry
floor should be designed with an outslope of
approximately three percent in order to provide for
adequate drainage of the floor. Compliance with this
design should be made a requirement of all operators at
the site.
