PEAK FLOW DATA.-` The area along River. Road has a long.,history-of flood events, occurring as wresult of not only high flows in Little .Chico Creek but from flows in the - Sacramento River.

River road'has{been closed numerous times in the past due to over bank flooding from the -Sacramento River. A primary concern eXpressed_ by County staff -during initial review of the proposed project was the impacts of potential increased stage (water . surface levels) ori' adjacent properties and River Road. it is generally y ackno«vledged that during a major event, such as the so-called 100 -year orthStar Engineering Page 1 flood, that much of the area will be inundated. What is of more concern are the more frequent events that have the potential to cause flooding to adjacent properties and result in more frequent closure of River Road. In order to establish floodplain elevations, field cross sections were taken at select locations. These locations and cross sections are depicted on Exhibit "A". Little Chico Creek is heavily vegetated with grasses, cattails and other woody growth that increases the friction, factor, contributing to the decreased capacity of the creek. Land leveling and levee construction along the east side of the creek has resulted in the creation of a low area where the plant and stockpile is proposed to be placed. This low area is drained through a 30" concrete pipe, back into Little Chico Creekat the southwest corner of the proposed plant site. The levee along the east side of the'creek affords some protection to.the area east of the creek where the plant is proposed. It is estimated that this levee will contain flows up'to a.once in five-year event. Hydrology Flooding of the area proposed for the plant site could occur from two sources. Little Chico Creek flows through the project area and will cause flooding during events that exceed the capacity of the existing, natural channel and levees. This is the source that has been used for modeling. In addition, over bank flows from the Sacramento River can enter the site through swales that cross River Road and enter the site at two locations downstream of the proposed plant site. These "swales" are identified in County records as the "brick house" and "Winelands", referring to the farm house and adjacent owners. During periods when this Sacramento River over bank flow is occurring, a backwater effect could cause an increase in stage in Little Chico Creek, should a subsequent event occur. This has not occurred during the period of record. NorthStar Engineering Page 2 02/26/2002 Little Chico .Creek, Looking.

What'is.more certain are the influence of the Sacramento River on flooding along-River Road.

Stream'channel'and over bank roughness. coefficients were developed North Star Engineering �, '•Page 4 02/26/2002 •_ .. yip •_ _. ,.. . „ and cross section data was entered. The site was field reviewed, since the area does not represent a typical stream channel due to the extensive land leveling and levee/road construction that has occurred. From field review and review of available mapping, it was determined that the area proposed for the plant and stockpiles is contained within levees/roads that impair the free return flow of over bank floodwaters to the creek channel. HEC RAS has an option for entering "ineffective flow areas that is areas where water is stored and the area is not available for conveyance. This data was entered for the area where existing levees do not allow free flow of floodwaters back into Little Chico Creek. In effect, the area proposed for the plant is acting as a storage basin by not allowing free flow into the creek. While the volume of water stored may not be significant, the levees do impede free flow. Since this is an existing condition, the in geometry input to the model reflected this situation. HEC RAS Model Runs Three model runs were selected to represent existing conditions and model the impacts of adding the plant and stockpiles. 1. Existing conditions recognizing the existence of the levee. 2. Existing conditions without the levee. 3. Overtopped levee with plant and stockpiles in place. The flows selected were based on the historic data from the Taffee Bridge gauge as well as the 10 and 50 -year design storms from the FEMA study so that this could be cross-referenced to information on road closures/ overflow depths from County records. Model Run 1. The model results indicate that the creek will contain flows up to approximately 2000 c.f.s. without overtopping the existing left bank levee. The presence of this levee causes an increase stage and hence the frequency of flooding River Road. Under this modeling scenario, River road is flooded at two locations; at the upstream cross section (Section 13) and Section 10, referred to as the "gas well location" in County road closure/ flooding reports. Of significance is the ability of these existing levees to confine flows to the existing channel and right over bank and not flood the proposed plant and stockpile site. Since the principal reason for modeling was to assess impacts to River Road and the adjacent Jones parcel, it can be concluded that storms with a return frequency of 5 years or less will cause no impact beyond what occurs at NorthStar Engineering Page 5 02/26/2002 present. Blows in excess of approximately 3000 c.f.s. will overtop the . existing levee at Section 10 and enter the stockpile /processing site. The return frequency of the event that would cause this is between 5 and 10 years. While the modeling suggests overtopping, this has not occurred during the events of the past 10 years. 2 Model Run 2. In this case, the presence of the levee was ignored, thus allowing free flow on the east side through the area where the stockpiles and plant are proposed. This decreased the water surface profile due to the larger waterway area. This model run acknowledged that the- existing levee system did not allow free flow to Little Chico Creek and created an ineffective flow area. Model Run, 3. The plant site and associated stockpiles were superimposed on the cross sections using a technique in HEC RAS known as blocking. The flows were then again run using this geometry to assess the increased water surface profiles and to determine the increase in stage. The results of the above models are contained in .the appendix and summarized in Table A Conclusions The present levee system protects (albeit without freeboard) the area proposed for the plant site and stockpiles from events up to approximately 5 -year storm. For the events that overtop the levee, the increase in stage -will be approximately one foot over the pre project levels at the plant site, diminishing to approximately 0.2 feet upstream at cross section 13. The only measurable impact will be to increase the stage at the low point in River Road near cross section 10 (gas well site) where the water surface would be less than one foot above pre project levels. This increase will cause more frequent flooding of River Road, but can be mitigated. Refer to mitigation measures. The increase in stage will also be reflected on the orchard property west of river road. This increase of approximately one foot could cause some additional flooding of this orchard. Since the orchard is owned by the applicant (M & T Ranch), the impacts will be known by them: I Herringer, Personal Communications NorthStar Engineering Page 6 • 02/26/200 TABLE A NorthStar Engineering Page 7 02/26/2002 RIVER STATION FLOW.

Overtopping Through Pit Area The frequency. and magnitude of overtopping of the Little Chico Creek channel in the vicinity of the pit `excavation has been expressed as a concern and a design issue. Cross sections 6, 7 and 8 were taken upstream of, and near the upstream limits of the pit. The model runs indicate that the creek channel proper has very limited capacity in this area. The capacity of the creek proper immediately upstream of the "pit" is on the order of 300 c.f.s. Overtopping can be expected to occur on at least an annual basis. The ten-year average peak flow of .approximately .1600 c.f.s. will cause overtopping and an average depth of 1 to 2 feet. This excess flow currently passes through the area proposed for excavation. During a site visit on January 9, 2002 a bifurcation or distributary was observed, wherein approximately 30% of the flow in the creek was flowing into this distributary. This "relief' currently minimizes the flooding impacts on the adjacent Jones parcel, where the thread of Little Chico creek currently exists. Assuming that this overtopping is allowed to continue and be controlled during the operation of the pit, no increased stage would be expected on the adjacent Jones parcel. The existence of this flow split presents a design challenge for the project. If a "levee" -were to be constructed to prevent this split flow, then increased stage upstream and through the Jones parcel could be anticipated. If the creek were to be allowed to continue to flow into the ' area proposed for excavation, then several issues will be raised, .including water quality, mining in a flowing stream and probably others. NorlhStar Engineering Page 8 02/26/200 0.1 0.4 0.4 Looking Downstream.at Bifurcation Overflow to Pit A mitigation measure to alleviate the direct flow through the pit as occurs now, and to also mitigate increased stage, would be to construct a low levee/ weir' along the downstream side of the creek. In conjunction with this weir, a bypass channel. would be needed along the west side of the.mine site that ,would take excess flows and mitigate the potential increased stage upstream and on the Jones parcel. This weir and bypass channel would have to be carefully designed so as to provide a continued flow into the creek thought the Jones parcel for environmental reasons. Overtopping of -the weir would be designed and expected to occur for events that exceeded -the 5 to 10 year recurrence interval. Careful design using a combination of hard armor (riprap) and bio -engineered Systems would keep velocities low and could distribute the flow over broad area. Given the very flat slopes -,and corresponding low velocities, erosion and failure of the weir leading to relocation of the creek�would'be unlikely. NorthStar Engineering Page 9 _ — 02/26/2002 LOOKING DOWNSTREAM AT PIT SITE ' A Design of the bypass channel -would require measures to control velocities and erosion potential. Given the substantial area available and' the low velocities expected this should be easily achievable_ TOPSOIL STOCKPILE , The, -question of increased flooding caused by placing -the overburden (topsoil) on'the designated site has•been raised. The propose stockpile for topsoil removed prior to=.ning is situated on an;existing rice field above the Little +Chico Creek floodplairn therefore will pose no increase' in j flooding. ANGEL SLOUGH 1 .: "e Angel. Slough is a minor tributary to Little Chico'Cree'k that,eriters the creek in two locations. The sough is actually'a series of swales that carry Sacramento River overflow into Little Chico Creek, and'- the I Butte Sink. The most northerly branch crosses River Road and'eriters at two' • locations upstream from the proposed stockpile site'. -As a tributary, this branch does not, contribute. significantly to peak rainfall., ruizoff; due to`; the small catchment and. its location. What is of interes`tazo«�evei is the -apparent seepage from the Sacramento River that 6nters:;this,upher ilorthStar Engineering.. Page 10 02126/2002 slough during high flows in the River. This is readily apparent in the aerial photos taken in January 1997. The quantity and impact of these flows would be very difficult to quantify, however, they are likely significantly lower than peak flows in Little Chico Creek. These flows appear to be the reason for "flooded" signs being placed at the low points on River Road at the "gas well". Refer to previous discussion on road closures. 4 The flows in the downstream branch location (identified on the Ord Ferry Q: ddrdnigl&`'as Angel Slough) are :directly related to overflows of the M&T weir, and to some extent to seepage from the Sacramento River. From examination of the 1997 aerial photos_, it is determined that these flows enter the project. site significantly downstream, approximately one half mile, from the area where the plant and stockpiles will be located. SACRAMENTO RIVER The Sacramento River distributes flows in excess of approximately 100,000 c.f.s. to the Butte Sink via several flow control structures (FRS). The control structure known as the M&T Weir is located on the left bank of the Sacramento River near River Mile 190. This weir is the most upstream FRS in the system. The operation of this weir is governed by the State Reclamation Board and is maintained by DWR. The regulations governing encroachments or reclamation acts within the "Butte Basin" are contained in Title 23, Water Code. The site of the proposed mine falls within Area B of this regulation. Approval of the State Reclamation Board is required for any "encroachment that could reduce or impede flood flows, or would reclaim any of the floodplain within the Butte Basin." The map accompanying this regulation describes the limits of the 1970 flooding and includes the project site. The EIR prepared for the Butte Basin Overflow Area in 1986 describes in detail the construction. and operation of the M & T Weir as well as two other flood relief structures (FRS) in the general area. The M & T Weir is the only FRS that could directly impact the proposed project. The frequency, depth and flow of these overflows however are not contained in this document. The M&T Weir is designed to discharge when gauge height at Ord Ferry reaches 111. Review of period of record information indicates that this stage has been reached five times between 1990 and 1998, therefore flows across this weir occur on. average once every two years or so. This corresponds with the County road sign records, further indicating that Sacramento River overflows are the primary reason for closures of River Road, not Little Chico Creek. As stated previously, the flows frorn this NorthStar Engineering Page 11 02/26/2002 weir contribute to the downstream reaches of Angel Slough, entering the project site well downstream of the plant facility. Impacts on Sacramento River Floodplain Due. to -the location of the project at the flood fringe, near the upstream limits of the designated floodway, impacts of placing the plant facilities and stockpiles within the Sacramento River floodplain will be minimal. The proposed site is not in the direct flood path of the M&T weir, based on available information. The increased stage of approximately one foot at the site and diminishing to .02 feet within_ 2000 feet is a local impact that should not be considered significant. Flooding of adjacent properties downstream of the plant facilities and stockpiles should not be an issue, since removal of material from the area will increase storage capacity and conveyance. Overtopping of the existing creek channel in the vicinity of the pit will occur on a frequent, annually or more often, and must be considered in the design of erosion control to minimize.the possibility of re-routing the creek through the pit. Due to restrictions contained in Title 23, .construction of new, higher levees to preclude flooding of the plant and stockpile site from Little Chico Creek is a very remote possibility. A much more feasible and defensible alternative would be to replace the existing levees with `setback" levees at the same elevation, on the east side approximately 200 ,feet east of the existing. The existing levees should be removed to increase the conveyance of the creek. The result would be'to decrease the stage in the creek by approximately 0.6 feet. If the setback'levee is designed as an integral part of the plant/ stockpile, the area between the site and the creek will be available for conveyance of overbank,flow. Northgineering Page 12 02/26/200 4 CONCLUSIONS Flooding impacts from Little Chico Creek associated with the placement of processing plant and stockpiles will be limited to events in excess of five-year recurrence interval storms that overtop the existing levees. Flooding impacts due to Sacramento River are very difficult to ascertain, since the operational characteristics of the flood relief structures are not defined. Sacramento River flooding events that overflow the M&T weir will in turn cause some flow to enter the lower reaches of the mine (pit) area via Angel Slough and the remnant of Little Chico Creek that passes through the Jones parcel. These events will not cause increased stage on adjacent properties since no fill will be placed in the pit area. The occurrence of this overflow has not historically coincided with peak flow in Little Chico Creek, thus should ,have little or no backwater impacts on the creek. MITIGATION MEASURES Little Chico Creek Impacts on River Road Mitigation 1. Replacing the existing levee. with a setback levee placed 200 feet east of the existing can mitigate the increased stage due to the stockpile and plant site. This levee should also be designed as an integral part of the plant/ stockpile. Removal of the existing levee will allow the over bank flow to return to Little Chico Creek, immediately downstream from the plant/ stockpile area. The existing levee on Little Chico Creek should be removed. Mitigation 2. Reconstruction of the "dip" in River Road at the low water crossing near Section 10 ("gas wells") by raising the roadway approximately three feet and replacingthe existing small culverts with larger ones will elevate the road above the flood elevation of Little Chico Creek and minimize the frequency of closures at this location. Larger culverts will allow excess Sacramento overflows to flow under rather than over the road. The culverts will need to be of sufficient size to accommodate this flow.

Supplemental Standards for Butte Basin. The standards apply to Butte Basin, as delineated on Figure 8.12 and partitioned into designated Areas B, C, D. E, and Reclamation District 1004. The basin's west boundary is the Sacramento River east bank proj. cct levee, and above the Ord Ferry area where there is no project levee, the boundary is the designated floodway of the Sacramento River adopted November 29, 1988. The east boundary is based on the wetted area of the 1970 flood. The north boundary is the Sacramento River des- ignated floodway in the proximity of Murphy Slough and Golden State Island, and the south boundary is the Sacramento River between the city of Colusa and the Butte Slough outfall gates, a section of the Butte Slough levee in both Colusa and Sutter Counties, and Pass Road in Sutter County. These standards supplement and, where in conflict with, supersede the standards in section I 1 I through section 137. (a) Approval from the board is required for any encroachment that could reduce or impede noodflows, or would reclaim any of the flood- plain within Butte Basin. (1) Encroachments in Reclamation District 1004 are not regulated by the board. (2) The supplemental standards do not apply to that portion of Area E located north of the Butte -Sutter County line and its extension westward into Colusa County, and situated adjacent to the Sacramento River proj- ect levee where the natural ground level is higher than the 100 -year flood elevation. (3) Except where the activity would potentially affect a project levee or other project feature, the standards within sections 116, 122, 123, 124, 126, 127, 129, 130, 131, 132, and 137 do not apply to that ponion of Area E located south of the Butte -Sutter County line and its extension west- ward into Colusa County. (b) Approval from the board is not required for crop checks less than thirty-six (36) inches in height. In Areas B, C and D, all crop checks must be removed prior to flood season, unless they comply with the require- ments of subdivisions (d), (e), and (f), respectively. (c) Except where the activity would potentially affect a project levee or other project feature, approval from the board is not required for land leveling or grading; or for drainage and irrigation improvements in Areas C, D, and E that have a localized impact only and comply with subdivi- sions (e), (f), and (gj of this section. 'r:u (d) Within Area B, approval from the board is not required for any croachment that is less than eighteen (I 8) inches in height above the n: ral ground level. However', any proposed encroachment within a slot or swale must be approved by the board. Area B extends southerly fr Butte Basin's northerly boundary to a line located one thousand (1,0 - feet southeasterly and lying parallel to the Parrott Grant line. (e) Within Area C, approval from the board is not required for any croachment less than thirty-six (36) inches in height above the natt. ground level, and having a crest elevation less than seventy and one to (70.1) feet (NGVD). Area C is the area enclosed within a three- (3) n radius measured from the center of Moulton Weir and limited by southeasterly extensions of the north and south training levee alignme to the three- (3) mile arc. (f) Within Area D, approval from the board is not required for any 1 croachment less than thirty-six (36) inches in height above the natu ground level and having a crest elevation less than fifty-four and n tenths (54.9) feet (NGVD). Areal) encompasses the Colusa Weir toge er with its outflow channel enclosed by training levees, and an overt , area extending to Butte Creek. .(g) Within Area E, approval from the board is not required for any r croachment less than thirty-six (36) inches in height above the natu ground level. The northern boundary of Area E is a line located one tht sand (1,000) feet southeasterly of the south Parrott Grant line, and I southern boundary is formed by the Sacramento River between the c of Colusa and the Butte Slough outfall gates, a section of the Butte Slou levee in both Colusa and Sutter Counties, and Pass Road in Sutter Coon (h) Within that portion of Area E located south of Gridley Road, m and existing recreational structures, including caretaker, security, a dwellings for seasonal occupancy (as defined in section 1 13) may be p, mitted provided the finished floor level of the structure is at least two r feet above the design flood plane or two (2) feet above the 100 -year flo elevation, whichever is higher. .

Tho groundwater velocity in the upper sand and gravel was. t%finwited to be about 280 to 500 feet per year. For surfaceo-wafer that may have entered the pit during thcwinicrr of .199.5, about 2.5 years elapsed in FA 1991. Groundwater moved about 70o to 1.,250 feet frorn the pit during this time period. Assuming that the surface water "entering the . pit. mixed completely with the water in the pit, contamination "that may have entered the pit would have traveled 700 to 1,250 feet or less in the shallow groundwater that is contiguous with. the pit, Well number 1 is - thus located at 1,00D feet from the pit in the main direction of growidwater flow. Similarly, surface water entering the pit during the 1996 and 1.997 storms could have traveled 420 to 750 and 140 to 250 feet from the pit in the shallow sands arad gravels, respectively, Therefore, wells 2 and I were located at 195 and 580 fed from the pit. Because there is uncertainty In the rate of groundwater movement, this placement of wells also provided some coverage if the - groundwater flow and contaminant transport rates are larger or smaller than the calculated rates. p The boreholes were drilled to about the elevat.10n of the bottom of the pit, Threaded PVC well cuing was imtallW in the boreholes that were sealed with bentonite from 2 feet above the screened interval to land surface. The wells were screened from the bottom of the well to the water table which is no mom than 10 feet. No Slum or solvents were used during the, installation. The wells were developed the day before sampling by pumping water until there was essentially ZOTO turbidity. Unfiltered samples were collected in glass containers by Nortlistate Water Testing of Chico.. placed on ice and trwisn-iittediramediady. to the laboratory for analysis. Constituents analyzed include trace metals and non-metals, volatile organic compoiinds, organophosphate pesticides, organochlorine pesticides, trium''Ile herbicides, phonoxy herbicides, tMombainate herbicides and nitrate. Glass sample bottles for organic compoun..ds, pesticides and herbicides were filled to leave no airspaot. The samples were held no more than 14 days before analysis. Swxnples for nitrate were analyzed within 7 days. Chain-of-cut.ody forms were filled out for all Samples, 2.0 Results and Discission The analytical results demonstrate that for the constituents analyzed, there is not a groundwater - quality problem associated with the existing pit. For all the organic constituents. analyzed which D-3.1 include pesticides and herbicides used near the site that are likely to move into groundwater, the concentrations are less than detectable. For the inorganic constituents, only aluminum.and nitrate, were detected. Aluminum concentrations range from 140 to 810 rnicrogramslliter. These concentrations are consistent with groundwater in equilibrium with aliiminosiliCate minerals present in the soil and aquifer. Nitrate conaelttrations were 7; 47 and 23 milligrams per.l ter in samples collect from wells 1, 2 and 3, respeo ively, For reference, the ma d=m permitted concentration in drinking water is. 44 mill grants per liter.
