BUTTE, STATE OF CALIFORNIA ~esolufion No. 90-179 A RESOLUTION OF THE PLANNING COMMISSION OF THE COUNTY OF BUTTE APPROVING AND RECOMMENDING TO THE BOARD OF SUPERVISORS THE ADOPTION OF A GENERAL PLAN AMENDMENT TO THE BUTTE COUNTY GENERAL PLAN WHEREAS, a private company, Robinson and Sons, has petitioned the Butte County Planning Commission, through an appropriate application, to amend the Butte County General Plan Land Use Element to change 13 acres of Industrial designation to Orchard and Field Crops and IS acres of Orchard and Field Crops to Industrial for that property identified on Exhibit A-I attached hereto; and WHEREAS, the proposed General Plan Amendment has been studied and reviewed by the Butte County Board of Supervisors and a public hearing held pursuant to law, at which time all interested persons were hearrl; and WHEREAS, the Butte County Board of Supervisors has reviewed and considered the contents of the environanental review study checklist (Exhibit A-2) prepared on the amendment pursuant to the California Environmental Quality Act; and WHEREAS, the Butte County Board of Supervisors finds the proposed General Plan Amendment and subsequent development could have a potentially signifccant impact on the environment, but will not in this case because of the Mitigation Measures which have been attached to the project and are described on Exhibit A-2; and WHEREAS, the Butte Board of Supervisors finds the proposed amendment complies with all elements of the Butte County General Plant and comprises an overall utternally consistent whole, specifically: 1. The project complies with the policies of the Butte County General Plan. 2. Adequate separation between noise generators and sensitive receptors is provided. 3. The land being changed to Industrial in its present state is not suitable for Orchard and Field Crop use. 4. The land being changed to Orchard and Field Crops is in an area designated for resource protection and extraction by the Energy Natural Renounces and Recreation Element currently to hearings. Adoption of the Element will require the subject properly as well as other areas within the County to undergo General Plan Amendments. The subject property is currently being studied as part of the Palermo-Honcut General Plan and Zoning study and is partially surrounded by existing Orchard and Field Crops designation. 5. The project site has direct access to the existing processing plant NOW, THEREFORE, BE IT RESOLVED the land use designation from Orchard and Field Crops to Industrial as shown on Exhibit A-1 are hereby adopted and approved by the Butte County Board of Supervioors as an amendment to Gridley Area Land Use Plan and Butte County Land Use Element, said amendment to be the land use policy for the County of Butte in the affected area far all frridings pursuant to law. BE IT FURTHER RESOLVED that the Initial Study and negative declaration prepared for the General Plan Amendment are adequate for this project for compliance with the California Environmental Quality Act BE IT FURTHER RESOLVED, pursuant to Government Code Section 65359 that the General Plan be endorsed to show the above amendment has been approved by this Board. BE IT FURTHER RESOLVED, pursuant to Government Code Section 65357 a copy of this resolution be transmitted to the City Councils of the Cities of Butte County.

DATE: November 7, 1.994 The attached initial study was prepared far the Robinson & Sons project which was a General Amendment, Rezone, Mining Permit and Reclamation, and Use Permit in the same general area in 1989. This current project seeks #a revert 13 acres of the original proposal back to the original General Plan and zoning, and to amend the General Plan and rezone another 13 acres for use as a quany. The resultant project size will be identical to the anginal approval, but 13 acres will be in a slightly different location. Comments received from responsible agencies at this time include comments from the California Department of Transportation which indicates that there may be traffic impacts an Highway 70. Apparently CalTrans was unaware that this project would utilize the private haul road approved in the first project to access the existing plant site an Robinson's property off Pacific Heights Road to the north, As such, Highway 70 would not be directly accessed by vehicles workitng the quarry. Since the project is essentially unchanged from the previous approval, the attached initial study is adequate -far consideration of this current project. DRHar Attach: Initial Study ~ .

Rezone - from "U" (Unc[-ossified - I single-fam[ly dwelling unit and ag uses per parcel) to M-2 {Heavy Industrial) an the same properties. Min[ng Perm[t/Reclamation Plan - to allow sand and gravel extraction and process[ng an I10 acres. Remaining property will be occupied by a buffer area. Development Agreement - to ensure that once the cond[tlons of approva€ are agreed upon, the use will be perm[tted for 50 years. Appl[cant has entered into a 50-year lease with the Department of Water Resources to allow gravel extract[on and processing. Other - Department of Water Resources .lease - Robinson and Sans and the Department of Water Resources have entered Into a 5D-year lease on the site. In exchange for the aggregate and use of the land, Water Resources will receive large ponds to tie managed by the Department of Fish and Game for habitat Improvement, and title to 280 acres located between the Feather River and Pacific Heights Raad, approximately I mile west of State Highway 70 near Orov[[le. ENVIRONMENTAL SETTING The property Is located In an area known as "Gold Dredge Fiats" along the Feather River. Hydraulic mining of the [BOOS and more recent channel dredging has Inundated surrounding agr[cultural lands with mine tallings. These tallings have no soil development; what ilttl6 soil exists has been deposited by wind drift. Riparian vegetation has became establ[shed on the talEing fringes where water is plentlfu[. Experience has shown that upon removal of the tallings, riparian vegetation will reestablish itself. ImmedlateEy north of the proposed mine site, tallings were removed for construction of the Orovllle Dam (cErca 1965). It took approximately 12-15 years to recolonize. The process of calanlzatlon can be sped up through reciamatlon and revegetatlon of the site. Geology - ^redger tallings are underlain by alluvium deposited fn the Holocene epoch (mast current). These Include stream channel and flaodplaln . deposits along the Feather, Sacramento and Yuba Rivers, and consists of sand, gravel, silt and minor amounts of clay. Permeability and -. surface lnfiltratlon range from moderate to high. ~~- H dralo ::.~_-: The min[ng Alts are located between 350 ft. to 2800 ft.., from the Feather River. Sven though spat[ally segregated, It 1s hydraulically Interconnected. Groundwater levels fluctuate with water Eevels~ln the Feather River. When River flows are [ow (400-1,000 cfs), water depths fn the ponds Immed[atefy north are 7 ft. River flows up to 10,000 cis Increase pond depth from I•to 5 ft.' At river flows above 20,000 cfs, standing water can be expected. (Reference: DWR Bulletin 117-18, Orovllie Borrow Area) The property suffered slgnifEcant flood damage In the winter of [986 even through it Es not a done A FEoodway. Groundwater on-site Is fresh, not brackish. Based an available data, water level contours in 1971 were 80 ft., 90 ft. In 1977. Depth to groundwater, Spring [965 (pre-Dam) ranged from i0 to 40 ft. Base of fresh groundwater fs approximately 800 ft. hEfgh permeability and Infiltratfan of the cobbles yield large quantities of water [n shallow wells. Are will yields are 500-1,000 gpm. Overdraft In the basEn Is not a problem; average annual recharge exceeds discharge. Tailings.are an Important aquifer recharge area. Vegetation/Wildlife A corridor of well-established riparian vegetation Is located along the Feather River. It is commonly made up of these species: Willows, Cottonwood, Sycamore, and Valley Oak are dominant; Elderberry, Black Walnut and Box Eider form a mid-story; Blackberry, Poison Oak, and Wild Grape are common shrubs. Many grasses and herbs occur.. As a habitat type, riparian should be considered endangered. (Reference: Department of Fish and Game Report) Revegetation of the excavated barrow areas has been rapid. Perladic ._. Inundation during construction has hastened the Introduction and • growth of phreatophytes, principally Willow- and Cottonwood. The edges of many ponds have filled in w[th dense riparian growth, notably Cattail, Mugwort, and Western Ragweed. Riparian supports the greatest wildlife densities and diversity of ail terrestrial habitats. Several species face extinction or extirpation because of Impacts on rEparlan. Mammals: Deer, Gray Squirrel, Beaver, Opossum, Red Bat, Cottontail, Deer Mouse, Red Fox and Ringtail. Birds: Bird activity is usually noticeable. Typical species are: Great Egret, Mallard, Wood Duck, Red Shouldered Hawk, California Quail, Screech Owl, Scrub Jay, f7owny Woodpecker,. Yellow-Rumped Warbler, and White-Crowned Sparrow. Fishllfe: Thirty-nine specter of fish either naw ex€st or can be - expected to exist in the ponds and canals and the nearby river. The _-_ undisturbed ponds continue to support warmwater fish populations. .. ..~: ~~..W::,:~ ~- _~~ -. Many of .the newEy excavated ponds and canals contain warmwater f[sh, which have traveled form the river ar adJacent ponds during overflow periods. One species usually predominates in any pond, with the Largemouth Bass found most frequently. The fist below 5haws the expected habitat of the most common game fish. ' The Feather River is the most important King Salmon spawn[ng tributary ]n the Sacramento River system. Habitat F1sh Species Rocky bottom ponds and canals Largemouth Sass, Smallmouth Bass, Green Sunfish, B[acK Crappie. Sandy or silty bottom ponds Feather River Largemouth Bass, BluegflE, White Crappie, Brown Bullhead. Smallmouth Bass, Green Sunfish, White Catfish, Channel Catfish, King Salmon (fall and spring runs), SteeEhead (winter and spr[ng runs), American Shad (June run), Striped Bass (June run). Species of special concern: Ringtail, Deer Mouse, Deer, Beaver, Otter, Cottontail. Birds: Bald Bogle, Peregrine Falcon, Ye[low- Tailed Cucicao. Plants: California Hibiscus, Black Walnut, Arabls Brewerlf. Land Uses Surrounding land uses west of the pasture, r[ce, same fallings and the river, most of the property is area, or occupied by taflIngs. pasture.

The wildlife area provides opportunities for fishing, Walking, blcyCl ing, swimmina_ wi Idl Efes nk~fcarv~+Fnn ~.,.a MINING OP1wRATION Robinson & Sans will remove and process mining taEE[ngs above ground elevation. Tailings are i0 to 30 feet high. The mine area Is 11mlted to i10 acres by the Water Resources lease. Mining will commence with building a pit. Depth is estimated at 50 ft. Side slopes will be 2:1 vertical. Rock will be removed from the two pit areas by means of dragllnes, front end loaders, dozers, and 80 ton bottom dump trucks. The rock wi[i then be taken north to the existing plant via a haul road approximateEy 3 miles long. The haul road will run west of Pacific Heights Raad and will be constructed of loco[ rock. Grading, sorting, stockpiling and crushing will take place a the existing Robinson Construction Ca. Plant off Pacific Heights Road. ENVIRONMENTAL IMPACTS Note: xB beneficial impact ia: P[t/pond construction could result in unstable geologic conditions. The pit's side slopes could cave Inward. Damage would be limited to the immediate mine site. Reclamation of the s[te pursuant to SMARA {Surface Min[ng and Reclamation Act) and the Fish and Game lease will ensure that the ponds are properly engineered, The Mining Permit will be conditioned. to require 2:1 slope an pit walls. Ib: Ta[ltngs cover the ent[re site; there is very little soli {se Environmental Setting). Alluvium underlies the cabbies at an unknown depth. The alluvium will be mined far sand and gravel t4 a total depth of 50 ft. (60 ft. above mean sea level}. IC: The site is presently covered by dredger tailings 10-30 ft. high. Ali tailings w111 be removed In the I10 acre pit area. the pits will slowly be dug, down to an estimated 50 ft. After mining, the land will be Eevel, with two large ponds. This [s a significant change from the present topography. The impact Is beneficial. Reclaimed lands will be suitable for wildlife habitat and recreation. If_ see items 3f,h. Ih: All of Butte County Is within a Moderate Earthquake Intensity Zone VIII_ No known faults are located within 5 miles of the praJect boundary, The pit structure as proposed should provide adequate _'_ stability in case of seismic activity. 2a: Deterioration Gf ambient air quality is possible from a number =----~- of different sources: ~ ~- *hau I roads ~ - --- - 8- -_ w - *loaders and crane load[ng and stockpl[ing materials *canveyars, screens *stockplles AIE of the above, except the loaders and haul road, are currently In use at the exlsting plant. As such, no add[tional slgnlfEcant Impacts should occur. Excavat[on Excavation of tall~ings, sand and gravel [s in many respects comparable to construction activity. The variable is the amount of property undergoing active disturbance. It Is est[mated that 2 acres w[EI be actively disturbed on any one day. An EPA emission factor far constructlon.sltes is 1.4 tons per month per acre of active _ construction. Multiplying i.4 by 2 acres yields 2.8 tans per month. Transport Excavated materials. will be transported to the aggregate plant via the haul road, north approximately 3 miles to the existing plant. e Plant g-g-raga ,..,_ At the exlsting aggregate plant excavated materia[s, sand, gravel and cobble are separated. There is very little dust generated because the material is kept moist dur[ng the process. A portion of that 1s used In concrete and asphalt is crushed and then segregated accord[ng to size. The gravel is Kept dry through crushing, screening and rehandling. Without dust controls, these operations can produce a considerable amount of dust. The EPA estimates emissions at .I Ib/ton of dry material for uncontrolled plants.' At 120.19 ~- 25p tons per hour, emissions are - 12.02 - 25 lbs. per hour. At l0 hours a day, 5 days a week (2[6.5 hours per month), 2602.33 - 54[2.5 lbs. per month could be generated. This w[!I be a continuation of the exist[ng use which has been in - operation approximately 2i years. Emilio ee Traffic Emissions Robinson & Sons will employ up to 2Q persons at the plant. Based on 20 employees making an average of 2.8 trips per day with an average - trip length of 10 tulles, the fallowing emissions will occur. .-. __.- -9- _ .. -...~. --, Composite Emission Factor Emissions, Pollutant (gram/ml) Mites/Da 1_bs./Day CO 24.23 560 29.91 NOx 2.41 560 2.98 TotaE: Hydrocarbons 3.26 560 4,02 Particulates .31 560 .38 The significance of any air poliutson source Is dependent on many factors: Surrounding air quatEty. Distance to receptors. Sensitivity of Receptors. Wind patterns. Dropout rate. Air quality on-site is good. The nearest residences are IE00 and 2800 feet west. Residences are sensitive. A second potent[ally sensitive receptor is reoreationists. Two popular f[shing spots are I I/2 and 2 I/2 miles west-northwest. A wind rose Is attached. Winds E~Iow towards the west 3.4%. and to the northwest 10.1% of the time. Accordsng to the F.E.I.R. sand and gravel operation River Bend Ranch, fallout rate of these materials Is: . 74.6% will fall out within 40 ft. 92.4°6 will fail out within 2000 ft. .._- 94.796 will fall out wlthln 5 miles. 99.4% will fall out wlthln I50 miles. Based on these rates, 7.696 of emissions may reach the residences when winds are E3lowing to the west and northwest.' 8.45% of the emissions may reach recreatsonists under the same wind Condltsons. ^ust can be mlt[gated by obtaining a "permit. to construct" from A[r Pollution Control, watering of work sites and haul roads, and planting of trees to the north and west In the I00 ft. buffer. 3b: on-site drainage patterns will change with excavation. No longer will water pond In small depressions. Alteration of drainag patterns will be limited to the mine site. A 100 ft. buffer o tallings surrounds the pit area and will contain stormwater runoff. After reclamation, drainage will return to a semi-normal pattern, flowing west-southwest to the Feather River.- The 100 ft. buffer of tallings will Impede surface flows. e -~ f 3e,f,h: No direct discharge to the Feather River is planned or permitted. However, by Its very nature, the mine may discharge to groundwaters thence surface waters. A pit wilt be Constructed. Groundwater Is expected to be intercepted at 10 to 40 ft. A Crane w[li remove materials below groundwater, and pile them up to dry. Excavation underwater will create turbidity. Constant disturbance wail keep particulates suspended. Groundwater flows to the river may flush these sediments out of the pit. Input from Regional Water Quality Control will be requested to determine if Impacts to the Feather River could be signif[cant. - 3J: Federal flood maps indicate the property 1s completely surrounded by, but outside of, a Zane "A" flood boundary. A S to $ ft. levee Is supposed to protect the land from flood. Reclamation Board maps (state of California) indicate the plant site is within the floodway. The 1988 flood washed out the levee road. During high water, pond and pit water will mingle with floodwaters. At this time, contamination is possible, but not of concern because of the dilution factor. Mln[ng operations weather floods fairly well. Ftoads are tied Into releases from Oroville Dam. Employees will have plenty of forewarning to evacuate. - 4a,c: The mine site is essent[a[[y devoid of vegetation {see iwnvlronmental Setting). After mining [s complete, the land will be managed by Fish and Game for wildlife hab[tat. The "pit" will be a freshwater pond stocked with fish. riparian vegetation will slowly colonize the perimeter. Colonization will be sped up through vegetation as part of reclamation. Improvement to wildlife habitat on-site is a beneficial Impact. Native species should be used. 5a,c: Reclamation of the site and recolonlzation by riparian vegetation will prov[de prime wildlife habitat for a multitude of species. Though the lease Is for 50 years, reclamation may occur in -.. as little as 15. These impacts are beneficial. Fish and Game has no ob1ectlons to the prvJect.

No mltlgat[on is necessary. 8: The property Is currentEy designated Orchard and Field Crap on the GeneraE Plan. Site designation criteria are: a. Sall conditions well suited to plant crop operations. b. Adequate water supply. c. Predominant parcel sEzes of 5 acres or more. d. Used for crop product[on or secondary uses. e. AdJacent uses compatible with primary and secondary uses. In its present state, the land Is not salted to agricultural production. An Industrial General Plan designation has been requested. Industrl~al 1s the only designation [n place which is suitable for the proposed use. Upon complet[on of the mine, a General Plan Amendment to Pubilc should be initiated, A suitable zon[ng category [s Public or Resource Conservation. A mine will promote intens[ve human act[vity In a remote area. The mine and related equipment [s visually much different from open expanses of rock piles. This Impact Is temporary, limited to the Ilfe of the mine. 9a,15a: Diesel fuel wli[ be utiElzed to power most of the plant`s equipment. Up to 130 gallons or more wIl[ be combusted each day. E3: Access to the pit areas will be via a haul road connecting the p[ts to th.e existing Robinson Construction Co. Plant on Pacific heights Road. The haul road will be approximately 3 miles long. .. Most access will be at the plant site, but two other access points are possible The first Is at the west end of Welsh Road (westerly extension of Palermo Road) and the other is where the haui road crosses the Oroville Wlidl[fe Area access road. Three gates across the hau[ road will keep unauthorized traff[c from accessing the pits or the haul road. (see Exhlblt "A") Robinson has been using part of the haui road to access land immediately southwest of the -plant site. That resource has been depleted and will be deeded to the Department of Water Resources (see Exhibit "D"). Truck traffic will simply continue south along the hau[ road to the new pits. Accordingly, no new traffic will be generated on area public roads. 14b: A security fence should be constructed around the site to -~- prevent unlawful entry. - 14d,19: The Oroville Wildlife Refuge ...borders the property to the north and east Intrusions of noise, traffic and dust may adversely affect the recreational experience. Although there are no developed _,~._.~- -~. facilities In the immediate vicinity, two popular fishing hoEes are within l I/2 and 2 1/2 miles. These fishing areas should not be adversely affected. Reclamat[on of the property for wildlife habitat will benefit Fish and Game and the residents of California. Robinson will deed 280 acres of river frontage to Fish and Game In exchange for mineral rights. The river frontage will became part of the wildlife refuge, apes to the public. 16a: Robinson will extend power to the site. Lines shau[d be discreetly placed. 16c: Water wIEE be supplied from the existing plant. 16e: Stormwaters will flow into the ponds. IBf: The lease specifically prohibits accumu[atlon of garbage or debris. References Butte County Plann[ng Department, "Green Rock Quarry EIR," 19$4.

Environmental Project Review AP 425-16-105 & 25-23-33,34 The project area and the lands surrounding it are man-altered breeding sites for disease vectoring mosquitoes, and any influx.of people into this area for what ever reason will, increase the risks of mosquito vectored diseases. It is our understanding that the altered landscape which results from this project will be left to the state as wildlife habitat for recreational purposes. Two large ponds will replace the smaller dredger ponds now present, as a result of rock and gravel removal.. This will eliminate the smaller mosquito breeding sources and make access into the area more convenient for our purposes. However the large replacement ponds may become a suitable masqui.to breeding habitat and a substitute problem for the smaller ponds, if constructed improperly. We have discussed this issue with Fish and Game Wildlife personnel who will regain use of the land after the project ends. As mitigation, we'wrould urge that the shoreline of the large ponds be constructed in such a way as to prevent any shallow vegetated areas for mosquitoes to breed in. The • shoreline banks should be clean and sharp along the edges. ~.. Aquatic vegetation that surfaces should be. kept~to a minimum . if not prevented, to discourage mosquito breeding. Control and maintenance of surface and shoreline vegetation may . require herbicide applications and therefore access should be provided for power-sprayers ar mechanical control - equipment_ _ .- _ ~ "J .T' If you'have any questions regarding our '- .~ -. _ reccomznendatians an this issue, please feel free to contact - - - - ,~__our office.
