ENVIRONMENTAL IMPACTS AND MITIGATION MEASURERS.
The material to be mined is composed of consolidated
sand and gravel. It is located in an embankment which
has been exposed through erosion.
The mining operation will further expose the face
of.the hillside. Through the extraction of material a
flat base area will be produced.
By eventually sloping the face of the residual
hillside and placing overburden on the flat base mined
area, indigenous plants, grasses, and trees will be
planted to rehabilitate the mined area.
ENVIRONMENTAL SETTING.
The mine is in a canyon called the Morris Ravine.
It is.located at an elevation of 800 feet; is two and
one half miles north of Oroville. In the late 1800's
it was the site of several gold mine operations, they
were in operation until the 1920's. Among the debris
left from the gold mines is the partial remains of a
building.
The hillside to be mined has eroded to a point where
the consolidated sands, composed of quartz, siliceous rock
and weathered greenstone are well exposed. Several old
piles of tailings exist in the immediate area.
The land in the area is used mainly for seasonal
grazing. The soil is of poor quality and very rocky.
Trees that grow in the region are: Interior Live.Oak,
Redbud, Mulberry, Manzanita, Cottonwood and Digger Pines -
In open spaces there are: Wild Oats, Bur Clover, Spurge,
Common Groundsel, Brush Morning Glory, Ragweed, Thistle,
Horseweed, California Poppies, a-nd Paintbrush. The
plentiful undergrowth contains. Poison Oak, and Nettle,
amongother low bushes; Mistletoe can be seen in some trees.
Some animals that frequent the property are Black Tail Deer,
Coyote, Porcupine, Raccoon, California Ground Squirrel,
California Mole, Common King Snake, Western Fence Lizard,
Mountain.Quail, and Wild Turkey. The State Forestry Fire
Department conducts periodic controlled burns of the area.
The adjoining properties consist primarily'of large
parcels used for seasonal grazing. There are a few small
acreage parcels near the southern boundary of the subject
property. There are a few dwelling on the small parcels,
most of which appear to be mobile homes. The nearest
neighbor is about one half mile distant.

12. GEOLOGIC DESCRIPTION, INCLUDING BRIEF GENERAL GEOLOGIC
SETTING, MORE DETAILED GEOLOGIC DESCRIPTION OF THE MINERAL
DEPOSIT (TO BE) MINED, AND PRINCIPAL MINERALS OR ROCK TYPES
PRESENT.
The mine is in a canyon called the Morris Ravine, and
is located at the 300 foot elevation level.The production site is
on a bench created by gold mining in the late twenties to early
thirties. A settling pond on the south side of the bench will be
repaired and reused. Part of the existing tailings piles will be
leveled to expand the production site.
The mining area is in a formation called the Ione, which
consists of white quartz-anauxite sands and clays. It is a high
hill of about 200 feet, that extends about one half a mile to the
east to a basalt cap, and covers about 350 acres. It is for the
most part consolidated sands with bands of gravel composed of
quartz, siliceous rock and weathered greenstone. Cross -bedding
is common and is brought out by streaks of red stain, due to iron
oxide.
The basalt cap has been eroded away at the mining.area,
leaving shallow overburden which will be stripped and saved
before underlying quartz materials are mined.
13. BRIEF DESCRIPTION OF ENVIRONMENTAL SETTING OF THE SITE AND
THE SURROUNDING AREAS. DESCRIBE EXISTING AREA LAND USE, SOIL,
VEGETATION, GROUND WATER ELEVATION AND SURFACE WATER
CHARACTERISTICS, AVERAGE ANNUAL RAINFALL AND OR OTHER FACTORS
PERTAINING TO ENVIRONMENTAL IMPACTS AND THEIR MITIGATION AND
RECLAMATION.
The mining site is a series of lulls with an abandoned
milling site as the production site fo-r the silica sand mine.
It is located two and one half miles north of Oroville in
mountainous terrain called the Morris Ravine. There are some
home sites in the area,.the closest one being about one half mile
to the south of the mine.
The land in the.area is used mainly for seasonal grazing.
The soil is of poor quality and very rocky. Trees that grow in
the region are: Interior Live Oak, Redbud, Mulberry, Manzanita,
Cottonwood,and Digger Pines. In open spaces there are: Wild
Oats, Bur Clover, Spurge, Common Groundsel, Brush Morning Glory,
Ragweed, Thistle, Horseweed, California Poppies, and Paintbrush.
The plentiful undergrowth contains Poison Oak, and Nettle, among
other low bushes; Mistletoe can be seen in some trees. The State
Forestry Fire Department conducts controlled burns of the area
periodically.
From core drilling in the area the closest ground water
was found at fifty feet. There is a seasonal pond one quarter
mile to the west of the mine. It dries up for the most part
about the middle of August. With the slope of the terrain, the
surface water eventually drains into lake Oroville. The average
rainfall in the area is between 15 and 17 inches per year.

Addendum (3) 1
18. MINING METHOD: TRUCK TO PROCESSING:
During the hours of operation we expect to maintain three
or four turcks, making five trips an hour to the production site
in Oroville.
ACCESS ROAD FOR MATERIALS TRANSPORTATION:
From the mining area, the raw sand will be hauled on the
mine access road. We will cross the Cherokee Road where the
Schirmer Ravine Road (a private road) intersects the mine access
road, and continue on the Schirmer Ravine Road. The Schirmer
Ravine Road intersects with Table Mountain Blvd. near the P.G.&E.
power line. We Turn left on Table Mountain Blvd. and continue
south to the Garden Drive entranceway to Highway 70. We turn
right on Garden Drive and pass over Highwa-y 70 then turn left
on�th amN of Highway ?0. We continue south on Highway 70

Feather River Blvd., where the production facility is located.
We reverse the process to return to the mine.
See Schedule (A)
19a. IF PROCESSING OF THE ORES OR MINERALS MINED IS PLANNED TO
BE CONDUCTED AT OR ADJACENT TO THE SITE, BRIEFLY DESCRIBE THE
NATURE OF THE PROCESSING AND EXPLAIN DISPOSAL METHOD OF THE
TAILINGS OR WASTE FROM PROCESSING.
The ore will be hauled to a location in the enterprise
zone in Oroville for processing. Ii has been established that
the enterprise zone is the most positive location for processing
the silica sand. The office, production facility, storage.silo's
and scales will be located at the Feather River Blvd. and Ophir
Road location.
We will purchase a multiple use service truck for use in the
mining operation. The vehicle will be used daily at the mine
site for minor repairs, lubrication of heavy equipment and the
fueling of that equipment. It will be road worthy as it will
also be used at the production facility for similar purposes'. It
will be garaged at the production facility and driven -to the
mining area as needed. There will be no fuel tanks taken to the-
minng site other than the one on the service vehicle.
19b. 7ESTIMATE QUANTITY (GALLONS PER DAY) AND QUALITY OF WATER
REQUIRED BY THE PROPOSED OPERATION, SPECIFYING PROPOSED SOURCES
OF THIS WATER, OF METHOD OF ITS CONVEYANCE TO THIS PROPERTY AND
THE QUANTITY AND QUALITY AND METHOD OF DISPOSAL OF USED AND/OR
SURPLUS WATER.
The quantity of water used per day will be approximately 5,000
gallons. The water- will come from a stock pond located on an -
adjacent property. The water is non-potoable and will be used
for dust control and other similar purposes. Our potable water
needs will be met by using a local potable water company.

20. IF THE NATURE OF THE DEPOSIT AND THE MINING METHOD USED WILL
PERMIT, DESCRIBE AND SHOW THE STEPS OF PHASES OF THE MINING
OPERATION THAT ALLOW CONCURRENT RECLAMATION AND INCLUDE A
PROPOSED TIME SCHEDULE FOR SUCH CONCURRENT ACTIVITIES.
The access road to the mine, an existing road, will be
improved to allow safe and convenient ingress and egress. The
road will remain unimproved, but will be maintained for smooth
travel, and watered by use of a water truck as necessary for dust
control. It will be necessary to trim some of the flora
encroaching. upon the road, from time to time.
At this time we do not anticipate doing any processing of the
mined materials at the site. We will have some stockpiles of
materials awaiting loading to be shipped to the.processing plant
in Oroville. The equipment maintained at the site will be self
propelled and is not be subject to special handling.
The hillside to be mined has eroded to a point where the
consolidated sands, composed of quartz, siliceous rock and
weathered greenstone are well exposed. The soil is of poor
quality and very rocky. The mining of this hillside will produce
a fairly level area of about 60 acres, with a backdrop of rising
hillside extending to the existing lava cap. This sloping area
will be about 300 feet high and 1500 feet long, With a 2:1 slope.
In preparing the hillside for mining, the overburden will be
stripped off and moved to a designated area, on the property. To -
avoid biological resource impacts, appropriate replacement of top
soil re -vegetation and other reclamation will be undertaken.
When the reclamation of the mined site occurs, the overburden
will be spread over the mined area using on-site equipment. This
equipment will consist of scrapers, dozers, motorgraders, and
water trucks.
The control of water runoff will be handled by allowing .the
water to enter a dry holding area that exists on the property.
Any silt that would be caught up in the water would settle out in
the existing holding area.
The slope will.be reclaimed using a hydro -seeder. Mulch and
seed will be combined, and is beneficial on the steep slopes
where erosion is a threat. A taci.fier will be used on the
steeper slopes if it is deemed necessary.
The project will be mined in phases. Reclamation will begin
in each phase as soon as it is depleted of commercially usable
material. Each phase will take approximately five years. Phase
one will be ready for reclamation about the end of 1998. The
remaining phases will follow in approximate five year increments.
When phase one has been completely mined, it will consist of
some ten level acres. Two acres will be reserved for the access
of mining of phase two. The eight remaininac=res will by
reclaimed by replacing the top soil, previously saved, and
hydroseeding it with grass seed. No trees or shrubs will be
planted on this level area as.it will be used as grazing land.
13
Addendum (3) 3
About five years later when phase two is completed, it will
consist of some ten level acres. Of those one will be set aside
for access to phase four. The remaining nine level acres will be
reclaimed by replacing the top soil, previously saved, and
hydroseeding it with grass seed. No trees or shrubs will be
planted on the level area as it will be used as grazing land.
There is some eight acres of 2:1 slope on the east side of phase
two which will be reclaimed. Pine trees will be planted on the
sloped hillside. 1
Phase three will be completed in the next five years and will
consist of three and one-half level acres. At this time, three
level acres will be reclaimed of phase three as well as the two
remaining acres of phase one. These five acres will also be
hydroseeded, with no trees or shrubs being planted, as to allow
for grazing of the area.
Phase four will be completed during the 20th year of
operation. It will consist of three and one-hal.f acres of level
land and three -acres of two to one sloped area. Three level
acres of phase four and the one remaining level acre of phase
three will be hydroseeded at that time. The three sloping acres
will be planted with pine trees.
The twentyfifth year of operation will see the completion of
phase five. It will result in four level acres, of which one
acre will be held out for access to phase five. The remaining
three acres along with the one-half acre of phase three will be
hydroseeded to add to the grazing area. No trees or shrubs will
be planted at this tiiw_-,
The operation will be completed by the end of the thirtieth
year. That will result in seven acres of level land to by
hydroseeded, completing the grazing area. There will also be
some ten acres of sloped hillside to be planted with pine trees
to complete the reclamation of the mined area.
Central Valley Hydroseeders, Inc. were contacted and
recommended a pre -mixed blend of seed. It consists of: Blando
Broam grass, Rimmera.Rye Grass, Creeping Red Fescue, Rose Clover,
Zorro Fescue and Califronia Poppy. L. & P. Nursery was
contacted and recommended the planting of a variety of'Oak
seedlings. These would come in the one gallon size. They also
recommended that the trees be planted approximately 20 feet apart
for maximum coverage.
The nature of the sand mined and the -method of mining it will
leave any walls at a 2:1 slope..

?E3.DEC- R IBE .O I L (:OND I •T I ONS AND PROPOSED �_O I L rALVA��E PLAN
THE soil is of poor quality and quite rocky. The hillsides show
areas of �.ti:Gsej rolisoli3at d sands and clays,
VEGETATION REMOVAL PLAN: The de -vegetation of the area to be
mined will occur in a timely manner to allow for a smooth
transition to the mining phase of the operation.
In preparing the hillside for mining, the trees and overburden
will be stripped off the immediate area to be mined. To minimize
the effect of stripping.the land, it will be done in 10 acre
increments. The trees will be taken to an area on the property
where they can be safely out up and disposed of. The resulting
slash will be mulched for safe disposal. Any leftover debris
will be piled and burned under safe and allowable conditions.
The overburden takin from the 10 acres will be stockpiled in a
designated area on the property. Berms will be constructed
around the stockpiled material, as needed, for erosion
protection. This material will be planted with native grasses to
inhibit wind and water erosion..
Reclamation of the mined out area will begin as soon as the phase
has been depleted. Local species of trees and grasses will be
replanted as per the plan developed by a Land Management Company.
27. DESCRIBE THE METHODS, THEIR SEQUENCE AND TIMING, TO BE USED
IN BRINGING THE RECLAMATION OF THE LAND TO ITS END .STATE.
INDICATE ON MAP OR ON DIAGRAMS AS NECESSARY. INCLUDE DISCUSSION
OF THE PERTINENT ITEMS LISTED BELOW.
a. BACKFILL & GRADING
As described in Section 23, the base of the site will be
level after the mining process is completed. It is planked that
the original overburden would then be graded back onto the site
and subsequently replanted with indigenous plants and trees.
There will be no backfilling required through the mining process.
b. STABILIZATION OF SLOPES
The material being mined is well consolidated in its
natural state, _o minimal li«� of erosion t-_ g -r
i ming -d =_:1G-pes is
anticipated. This is evidenced by examination of the existing
wall of material that has been exposed to the elements for many
years. This wall of consolidated sands is vertical in nature and
has remained very stable with little evidence of sloughing. The
plan is to bench the north side of the mining site and bcnch the
east side. All mined portions will be sloped to drain into the
natural drainage of the Morris Ravine. See diagram.
C. STABILIZATION OF PERMANENT WASTE DUMPS, TAILINGS, ETC.
Mentioned in Section 19a, the residual heavy impurities
left over from processing the sand will be sent away for further
processing. The remaining.by-product of the operation will be
silty clay. This will be periodically dredged from the settling
ponds, air dried, and eventually be used as topsoil.
W
Addendum (6) 2
d. REHABILITATION OF PRE -MINING DRAINAGE
Current natural drainage channels will be maintained in
channeling the winter run-off into the Morris Ravine.
e. REMOVAL, DISPOSAL, OR UTILIZATION OF RESIDUAL
EQUIPMENT, STRUCTURES, REFUSE, ETC.
All equipment stationary or mobile will be removed from
the mining property at the end of the project; refuse will.not be
allowed to accumulate. Although no permanent structures are
planned at this time; if there should be in the future, these
would either be dismantled or used for future mining operations,
feed storage of domestic animals, etc, Existing debris,
remaining from previous mining operations, such as derelict
building, concrete, metal etc. that might present a hazard and an
eyesore to the operation, will be removed. The property's
.appearance will be enhanced by this removal.
f. CONTROL OF -CONTAMINANTS, ES-PECIALLY WITH- REGARD TO
SURFACE RUNOFF AND GROUND WATER.
The anticipated contaminants on the site will be those
naturally occurring in the raw sand. These minerals will be
hauled away for further smelting and processing. Contaminants,
such as waste oil, solvents, etc. will be disposed of by removal
to re -cycling centers. The nature of the silica business is to
maintain the mining site relatively free of anything that would
contaminate the silica sand. Cleanliness is very important at'
the mining site, for amounts of even a few parts per million
could result in rejection of the finished silica sand product.
No chemical compounds are anticipated at the mining site that
could contaminate the groundwater or constitute problems with
surface runoff.
S. TREATMENT OF STREAMBEDS AND STREAMBANKS TO CONTROL
EROSION AND SEDIMENTATION
No established natural streams are in the proposed mining
area. No impact with regard to erosion and sedimentation of any
streambed is anticipated.
h. REMOVAL OR MINIMIZATION OF RESIDUAL HAZARDS
Mining of the property will remove material laterally into
the hillside, eliminating the hazards of pits, and mineshafts.
The mining process uses no chemicals that might constitute a
public: hazard: Thi; py.apji_-rty. will b a laft In an iYflp .QVE' d _tate
compared to its present condition.
i. REBOILING, REVEGETATION WITH EVIDENCE THAT PLANTS CAN
SURVIVE GIVEN THE SITE'S TOPOGRAPHY, SOIL AND CLIMATE.
As described in b, the area will be recovered with
salvaged and processed topsoil, then planted with grass, plants
and trees indigenous to the area.

RECLAMATION., DESCRIBE IN DETAIL THE SPECIFIC RECLAMATION TO BE
ACCOMPLISHED DURING FIRST PHASE.
As per the Reclamation Phasing Map, The mining will.commence
in the area designated ONE. We anticipate starting to mine at
the 700 foot level, and maintain that level as our base. We do
not anticipate excavating at any level below the 700 foot
level. It will take five years to complete area one. At that
time we will reclaim 600 feet of area ONE.
Area TWO as designated on the map will be mined during the second
five years of operation. At the end of ten years of business we
will reclaim 600 feet of area TWO.
Areas THREE, FOUR, FIVE AND SIX, are steeper and require less
footage to mine the required material per year. At the end of 15
years we will complete mining area three and finish reclaiming
area ONE. At the end of twenty years we will finish mining area
FOUR and complete the reclaiming of area TWO,
At the end of 25 years area FIVE will be completed and 200 feet
of area THREE will be reclaimed. At the end of thirty years the
project will be finished and area FOUR will be rehabilitated_ as
well as areas FIVE and SIX.
The mined area will be level at the 700 food level with two to
one slopes extending from the northern and eastern mined areas.
A4 -41 DESCRIBE HOW RECLAMATION OF TH I S S ITE IN TH I MANNER MAY
AFFECT FUTURE MINING AT THIS SITE AND IN THE SURROUNDING AREA.
The replacing of the overburden' upon the leveled mined
area protects the underlying strata from erosion. It would not
be too costly for one to again remove the overburden and .commence
mining Silica sand. The improvement by leveling of the mining
area would enhance the development of an open pit placer
operation. The improving of the road would enhance other
potential mining operations in area.
