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.

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. 11 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 tM�c re we turn left to the corner of Ophir Road and 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. A 12 Addendum (3) 2 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..

Addendum (6) 1 ?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. 20 Addendum (8) 3. IF APPL I C=ANT HA = ELEC_ TED A :SHORT TERM PHASING OF H I 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. 21 22 PROJECT NO. : 93-36 A.P.#041-220-050 Response to potential impacts to the environment caused by the mining project. 1b.
