INTRODUCTION This report provides the results, conclusions and my professional opinions regarding the groundwater potential at the Moonridge Vineyards. The property is located at 5420 Cavedale Road in the Mayacamas Mountains east of Glen Ellen, California. The property is shown approximately on Plate 1.

Scope and Purpose The purpose of this work was to assess the groundwater potential of the vineyard property for the purpose of drilling a new irrigation well. Apparently, yields have decreased in the existing well to a point where the irrigation needs are not being met. To accomplish the stated purpose the following tasks were performed:

· Geologic literature and well logs pertinent to the site were reviewed. Literature reviewed is provided in the Reference section at the end of this report.

· Stereo-paired aerial photographs were viewed and interpreted to provide a preliminary understanding of the site geology.

· Three site visits were performed to view the general site conditions, map the geology exposed and stake proposed exploratory borehole locations.

The results of the work and my professional opinions are provided in this report.

SITE CONDITIONS General Site Description The property is located on gently to moderately inclined west-facing slopes near the ridge crest of the Mayacamas Mountains. The property straddles the boundary between Sonoma and Napa Counties and elevations range from about 2075 to 2380 feet (sea level). Runoff from the site descends westerly to Stuart Creek about a mile west of the property. Most of the property is developed to vineyards with the upper and lowermost areas covered by forest. Site development

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 1 includes a main residence and an abandoned homestead and barn located along the lower edge of the vineyards near the southwest corner of the vineyard area. The climate of the area is Mediterranean and classified as “coastal warm” (Vossen, 1986), meaning the marine influence is largely blocked by mountains with the area protected from the cool temperatures and coastal fog associated with a marine influence. Summer temperatures occasionally reach 100 degrees, however a late afternoon or evening breeze typically moderate the higher summertime temperatures. Winters are mild and wet with nearly all precipitation occurring as rain between the months of mid-October through April. The annual precipitation averages between about 40 to 45-inches/year (SCWA, 2005). The summer and early fall months are warm and dry.

Wells and Springs One active well and several springs currently supply the property’s irrigation and residential water. The well is located near the residence and was drilled in November of 1983 to a depth of 410 feet deep. The initial water level was at a depth of 300 feet, however in June of 2013 the water level was 341 feet only about 15 feet over the pump (Weeks, pers. comm..). At the time of drilling the well was estimated to yield about 13gpm (Fisch Bros., 1983), however a pumping test performed in June of 2013 estimated the rate to be only 2¾ gpm. Two springs are located on the property as shown approximately on Plate 1. Spring S1 is in the vineyard area south of the residence and has a reported discharge of between about 1 to 2gpm. Discharges from S1 flow into a small pond. A second area of spring seepage (S2) is located just north of the homestead buildings. The presence of cattails indicated the seepage at that location persists on a year-round basis. Two seasonal ponds are located upstream from the second spring. The pond levels are reported to decline during the summer, but they maintain some water year-round, likely as a result of small springs. A neighboring well is located below the property and across Cavedale Road. It was drilled to 600 feet, but water-bearing materials were reported to be above about the 380 feet.

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 2

Initial estimates of well yield were about 50gpm, however those were initial yields and like many of the wells in the area the long-term capacity is likely to be substantially lower.

Site Geology Franciscan shale (map symbol KJf) was reported by the well driller as occurring near the bottom of the vineyard well. The occurrence of the Franciscan shale at such a high elevation is considered unlikely, but possible, so it is shown as reported near the bottom of the main well. Refer to Plate 3, Interpretive Geologic Cross-Section A-A’. Published geologic maps indicate that the property is underlain by rocks of the Sonoma Volcanics (Tsv) with a large, ancient landslide (Qols) possibly affecting much of the central property area. Some maps indicate that nearly the entire site is underlain by ancient landslide deposits, and although the extent of landslide deposits was not confirmed as part of this scope of work, it was concluded for purposes of evaluating the groundwater behavior that these deposits affect much of the vineyard areas. The Site Geology Map on Plate 2 shows the approximate distribution of various geologic materials. Landslide debris (Qls and Qols) was exposed in cut slopes along the lower access road (jeep trail) that leads to the abandoned cabin. Where exposed these deposits were comprised of a mixed of volcanic rock rubble with large fragments of hard lava flow rock as well as blocks of friable ash. The basal slip plane of the slide is interpreted to be related to the weak clays in the tuff that occur at depth and dip downward in a westerly direction (Refer to discussion below). The Sonoma Volcanics within the property are predominantly comprised of volcanic ash. The ash (tuff) occurs as both massive and friable (Tst), and as a gray, welded and relatively brittle ash flow tuff (Tsw). Lava flow rocks (predominantly andesite with some basalt, Tsa) were also present and a thick sequence of basalt was encountered in the vineyard well between depths of about 205 and 340 feet. Similar rocks were exposed on the steep slopes east of the vineyard areas on the “Napa County side” of the ridge. The tuff (Tst) was typically light brown to yellow-brown and/or white, relatively fine-grained and massive and friable. Localized areas of weak, plastic clay beds were present within the ash layers. The lava flow rocks (Tsa) were gray to black, hard and frequently fractured.

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 3

Downslope and off-site dense forest obscured rock exposures however based on scattered outcrops and the site topography volcanic rock strata appeared to be limited laterally either as a result of its original depositional condition or due to disruption by slope movement related to landsliding. In either case the lava flow rocks were laterally discontinuous and irregular and difficult to follow for more than a few hundred feet in any direction. Uplift from tectonic forces has tilted and gently folded with the volcanic rock strata with bedding dips descending toward the west-southwest. Where observed in the east-facing, steep slopes east of the ridgeline the ash strata were observed to dip between about 15 to 20 degrees down toward the west.

GROUNDWATER CONDITIONS Open Rock fractures provide the otherwise impermeable volcanic rocks with their capacity to store and transmit groundwater. The brittle, relatively strong volcanic rock types, primarily the lava flow rock (Tsa), and to a lesser extent, welded ash (Tsw) have a substantial capacity to contain open fractures, and the networks of open fractures below the water level comprise the aquifers in these rocks. The 410-foot deep Main well encountered basalt at depths from 205 to 340 feet deep that were likely the primary water-bearing at that location. The friable ash, in contrast to the brittle fractured rock types, tends to be massive with few fractures and containing an abundance of fine-grained particles that tend to infill those fractures that are present. These characteristic render the ash (Tst) a generally poor candidate for groundwater. The landslide debris is a heterogeneous mixture of clay and broken volcanic rock that was moved downslope and in doing so created numerous areas of broken rock and soil-filled fissures that provide the slide mass with a capacity to store and transmit useful quantities of groundwater. Groundwater infiltrating into the slide mass during the winter rains becomes perched above the landslide plane, which is usually composed of a plastic, low permeability slip surface located at the base of the slide. The weak clayey tuff observed east of the ridgeline and dipping moderately toward the west is considered to be a likely candidate material to have contributed to sliding. Based on wells located west of the ridge, the base of the slide deposits are estimated to on the order of up to about 150 feet deep. The springs present within the vineyard

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 4 and near the homestead are interpreted water seeping out of highly fracture and broken lava flow rock that is part of the slide mass. Rainfall and local surface waters (including irrigation and pond leakage) provide the source of recharge for all of the groundwater at the site. Surface water infiltrates into and through permeable materials and moves into the subsurface where it accumulates in highly fractured rocks. If significant quantities of water accumulate, then an aquifer is formed. Because the occurrence of precipitation is highly season, with nearly all rainfall occurring between about mid-October and May, recharge is also seasonal. This seasonal nature of recharge is reflected in water levels and spring discharges that typically rise during the winter and early spring and decline during the dry summer and early fall. As would be expected, shallow aquifers tend to be most responsive to the variations in the annual precipitation; deeper aquifers tend to respond more slowly with their water levels reflecting cumulative recharge or storage loss that may have occurred over a period of several years. The reduced groundwater availability in the main well is apparently a response to a series of dry years, including this past years unusually low precipitation, suggesting that the aquifer utilized by the well has experienced low recharge rates, but pumping was not reduced proportionally resulting a depletion of water held in aquifer storage. Several factors act to inhibit recharge to the aquifer(s) utilized by the main well include 1) the limited area above the site capable of generating surface water (the well is near the ridge line); 2) the presence of clayey ash/landslide plane in the subsurface that would impede the movement of water down to aquifer materials located below those clays zones; and 3) the limited surface exposure of the aquifer materials where they project out of the steep-east facing slopes where recharge would be most direct.

DISCUSSION AND CONCLUSIONS

Groundwater Potential Based on the site geology, there appears to be a reasonably favorable potential to drill one or two new wells capable of providing useful quantities of irrigation water, however the limited recharge capacity of the site indicates well discharge volumes and discharge rates should be

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 5 modest and carefully monitored to reduce the potential for depleting the site aquifers that apparently recharge relatively slowly. Until the capacity of individual wells are understood, based on regular monitoring of water levels and discharge volumes, care should be taken not to overpump. The general nature of wells in the project vicinity is of relatively modest yields from a few gpm to several tens of gpm. Often, when a well is first drilled, the reported yields are substantially higher than those experienced over the long-term. This is because initially a high volume of groundwater is held in aquifer storage and available to the well, but after pumping has progressed for a period of time, particularly during the dry summer months or during a drought, groundwater in storage is removed and the well yield and water levels decline. This is likely to be the case at the site and it should be anticipated that successful new wells would be of modest yields, perhaps on the order of 10 to 20 gpm, and experience seasonal fluctuations in the availability of groundwater. If recharge is greater or equal to withdrawals, then water levels would recover during the wet winter months and restore the groundwater as indicated by restored water levels. The water supply would be more likely to be sustained on a long-term basis by pumping modest volumes from several individual wells, rather than heavy pumping from one or two wells.

Groundwater Exploration Two locations are proposed for exploration drilling. Both are at the lower property elevations to improve the quantity of water available from that portion of the aquifer(s) located at high elevations toward the east. The first boring (it is proposed that M1 be drilled first) should extend to a depth of between about 700 to 800 feet to explore for water-bearing materials below the suspected aquifer that is supplying the main well. If no worthwhile groundwater is encountered at the deeper intervals, then it may be appropriate to reduce the depth of the second borehole, M-2, if it is drilled. Site M-1 is labeled M-2 on the field stake. Site M-2 was not field staked; however the image on Plate 3 should be sufficient to locate the drill site. A boring located within about 25 or 30 feet of the “stick pin” shown on Plate 3 is sufficient.

Access to either site is either by descending the relatively steep vineyard roads from the residence area or by driving in along the old homestead road (jeep trail) if an easement exists. If the lower road is used some tree trimming may be necessary and the soft, wet seepage area near the homestead may need to be improved. Drilling Methods. Well drilling should be performed in a manner that recognizes the uncertainties of groundwater availability and the importance of proper well design by collecting and evaluating geologic and groundwater data as the exploration work proceeds. This data, even from unsuccessful boreholes, can prove useful in refining an understanding of the site geology and potentially lead to adjusting the exploration program in a timely manner as the project progresses. If feasible the exploratory borings should be drilled utilizing air rotary methods, however based on previous drilling at the site it is considered likely that the driller could opt to drill using mud rotary methods. Use of mud during drilling can obscure the presence or absence of groundwater as the borehole advances and in a completed well any mud remaining in the borehole tends to clog the rock fractures and inhibit the entrance of groundwater into the well casing. As a boring is advanced the driller should collect representative samples of the rock cuttings at intervals of at least every 5 to no greater than 10 feet and place the samples in a well ordered manner at a location protected from the drilling operation or in clearly labeled, zip-lock baggies for viewing by the geologist. The driller should carefully note changes in the drilling conditions and the depth and quantity of groundwater encountered as the borehole advances. Drilling should continue as long as favorable rock conditions persist, because the seasonal nature of groundwater availability indicates that a well’s performance would be improved by intersecting as many water bearing zones as possible. Upon the completion of the pilot bore or well bore, downhole geophysical logging should be performed to identify the depth and groundwater potential of various strata. The suite of logging tools should include resistivity (point, 16-inch and 64-inch normal), spontaneous potential, gamma and temperature. The geologist should be informed of the drilling progress and findings in a timely manner and be provided the opportunity to visit the site to view the sample of the drill cuttings, review the results of the geophysical survey and provide the driller with

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 7 input regarding the well design. If the borehole information appears suitable for a well, then the borehole should be reamed to a diameter sufficient to allow a minimum of a 2-inch thick filter pack to be placed uniformly between the casing and the formation. In the landslide deposits the filter pack should be placed using a tremie pipe to prevent segregation of the filter material which can contribute to entry of loose fines into the well casing and turbidity. If an exploratory boring encounters suitable groundwater conditions and a well is constructed, then the well should be constructed with a blank casing (cellar pipe) that extends at least 10 below the lowermost water bearing zone. This is intended to maximize the amount of groundwater available to the well by allowing the pump to be placed below the lowermost water-bearing zones, if necessary. If drill muds were used the well should be thoroughly developed to remove all drill fluids and mud from the borehole wall and surrounding formation using mechanical, chemical and pumping techniques. Proper well development is an essential, and often neglected, aspect of constructing an efficient well. A minimum 20-foot sanitary seal should be constructed if the well water use is limited to irrigation use. If the well water is to be used for public consumption, then a 50-foot minimum seal is required.

Aquifer Testing Pumping tests are considered an important method for characterizing an aquifer’s capacity to supply a well and for projecting water levels at various discharge rates. During drilling and development of a new well discharge rates are typically estimated by the drillers, and although these estimates are useful in providing an initial estimate of a well’s possible yield, they are commonly higher than the actual long-term well yield. In a low yield well the actual long- term discharge can be 3 to 5 times lower than the initial estimate; in a well with a moderate yield the long-term discharge can be 2 to 3 times less than the initial estimates. Therefore, once a well has been constructed and thoroughly developed, it is important to perform pumping tests to characterize the aquifer’s behavior when it is subjected to sustained pumping, especially if significant investments are to be made based on the well’s yield. Additionally, the pumping tests

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 8 can indicate an efficient pump size and setting depth for efficient well operation and reduced pumping costs. It is anticipated that if testing were performed it would include a three phase step-test followed by a 24-hour constant rate test. Until wells have been tested, or pumped and monitored for a year or more, their actual capacity should be considered uncertain.

Groundwater Management It is strongly recommended that water levels in existing and future wells be measured regularly (monthly) throughout the year and every two weeks during the irrigation season in order to reduce their potential for unexpected water shortages and to optimize well yields. As mentioned previously, initial well discharge rates are often significantly higher than can be sustained over the long-term. Management of the groundwater resource by regularly measuring water levels and discharge volumes can identify decreasing water availability before over- pumping of the aquifer occurs and thereby reduce the potential for unexpected water shortages. Groundwater management should include both installing a totalizing meter on the well’s discharge line to track the volume of water discharged and regular (at least monthly) water level measurements as discussed above. To monitor water levels an access port and ½-inch diameter open ended PVC tube should be installed into the well. The tube makes insertion of a sounding tape or pressure transducer relatively easy with little potential for it to become snagged and/or lost in the well. A static water level should be taken by allowing the pump to remain off for a sufficient period of time that the water level stabilizes. A pumping level should be taken when the pump is running and the water level is at or near its lowest level in the pumping cycle. By regular monitoring of water levels is it possible to assess whether or not the water levels are stable or declining. Operating wells in a manner that produces large and rapid drawdown of water levels should be avoided because that procedure can induce a number of problems including damage to the well casing, accelerated clogging of well screens and loss of aquifer capacity. Therefore, if practical, it is recommended that the wells are pumped at low to moderate rates with periods of high demand supplemented by water held in storage tanks or the ponds. A common mistake is

Michael S. Malone – Consulting Geologist 1247 Jean Dr. Sebastopol, CA 95472 TELE: (707) 829-5511 9 pumping at a rate the well is initially considered to be capable of without consideration to whether or not the volume of water in aquifer storage can support that discharge rate over the long-term. In conceptualizing a fractured rock aquifer in a situation where recharge is seasonal, it can be useful to think of the aquifer as a tank of some unknown, but fixed volume. Water can be removed from the tank at a high rate, but ultimately the available water will become dependent on the rate the tank is being filled.

Water Quality Testing Water quality from the Sonoma Volcanics is usually suitable for both domestic consumption and irrigation. It is assumed that the water quality from the existing well has been previously tested both for irrigation and residential consumption and was found suitable for both uses. It is recommended that water from all new wells be sampled then analyzed for water quality constituents and characteristics pertinent to the intended use. Samples for analysis should be collected after sufficient water has been discharged from the well to ensure collection of a representative sample of the aquifer water with minimal influence from the well construction and materials. Samples can also be collected during the drilling process and analyzed for important agricultural constituents, such as boron, before a well is constructed. Bacteriological testing should be performed after the well has been disinfected. Wells that are to be used for public consumption should be constructed in accordance with the California Water Well Standards and include a minimum 50-foot sanitary seal. Wells dedicated to irrigation can be constructed with 20-foot minimum sanitary seals in accordance with the State Standards.

Additional Services At your request I would be pleased to provide you with additional services in support of the exploration drilling and aquifer testing. These services could include geologic logging of the drill cuttings and review of the downhole geophysical log (if performed) in order to assist the drillers with their decisions regarding extending or reducing the borehole depths based on the actual geology encountered. Additionally, I could provide the driller with my opinions regarding appropriate depths for well screen placement.

LIMITATIONS This report has been prepared in accordance with the generally accepted standards of the hydrogeologic profession. No warranty, either express or implied is given. It should be recognized that the conclusions provided herein are interpretive in nature and if verification of these conclusions is required, then additional investigation may be necessary and could possibly include exploration drilling, geologic logging and water level monitoring. Well logs, water levels, historic water use, well behavior and other pertinent data used in this report were obtained from a variety of sources and I can neither verify not be held responsible for the accuracy of any data provided to me. This report concerns water availability and physical aquifer conditions, consequently pump performance, well life, corrosion, groundwater and soil contamination and water treatment requirements are beyond the scope of this assessment. This assessment of the groundwater resource is general in nature and does not preclude the need at some time in the future to drill new wells, deepen wells, reset pumps deeper and/or reduce usage depending on variations in climactic and land-use patterns. This report specifically does not address stability related to slopes or landslides. If information regarding those conditions is desired a qualified firm experienced in slope stability evaluations should be consulted.

Subject: Biotic Resources Assessment of the Proposed Cannabis Lunar Ridge Farms Project Sites at 4800 and 5420 Cavedale Road in Glen Ellen, Sonoma County (APN #053-051-038-000 and 053-051-033-000

Dear Korbin:

At your request, LSA conducted a biotic resources assessment of the above-referenced project site; the assessment was conducted to fulfill part of the Sonoma County Department of Agriculture/Weights and Measures Medical Cannabis Permit Application process. The permit application requires a biotic assessment to identify any biological resources that could be adversely affected by the proposed medical cannabis outdoor farm. This report provides an assessment of the status of special-status species, sensitive biological communities, and wetlands and other waters under the jurisdiction of the U.S. Fish and Wildlife Service (USFWS), U.S. Army Corps of Engineers (Corps), the Regional Water Quality Control Board (RWQCB), and/or the California Department of Fish and Wildlife (CDFW). This report also analyzes the biological resources on the property in regard to the California Environmental Quality Act (CEQA).

PROJECT DESCRIPTION The proposed project is a medical cannabis cultivation farm that includes a storage container site and two outdoor growing areas referred to as Grow Sites A and B (Figures 1 and 2). The growing areas are located within the Korbin Kameron Wines vineyard. Grow Site A is situated in an area previously occupied by vineyards, Grow Site B is in area previously cultivated for farming purposes from the original homestead, and the storage container site is situated vacant ruderal grassland area adjacent to an old homestead and barn (Figure 2). The cannabis plants will be grown in large container plants that will receive drip irrigation. None of the plants will be planted in the ground.

METHODS LSA senior biologist Dan Sidle surveyed Grow Sites A and B and the storage container site on July 25, 2017. During the survey, LSA assessed whether any sensitive biological resources were present that could be impacted by the proposed project, particularly the presence of special-status species and jurisdictional wetland features. Plants and animals observed were recorded in field notes.

Before conducting the fieldwork, Mr. Sidle reviewed the CDFW California Natural Diversity Database (CNDDB) to locate records of special-status species and habitats known to occur within a 5-mile radius of the project site.

RESULTS AND DISCUSSION Existing Conditions The two grow sites and storage container site occur within an active vineyard that is intermixed among mixed evergreen forest, riparian woodland, drainage channels, constructed ponds, seeps, buildings, and dilapidated structures (Figures 1 and 2). Elevation at the sites is at approximately 2,100 feet above sea level. Soil types mapped at the site consists of Suther loam, 15 to 30 percent slopes, which is a moderately well drained soil (USDA 2017). Tables A through D (attached) list the plant and wildlife species observed at the sites.

Grow Site A Grow Site A contains a mowed, fallow non-native annual grassland field that was previously planted with a vineyard and has since been planted with a cover crop seed mix. A seep and small constructed pond is situated to the northeast, a unnamed drainage channel and riparian woodland is situated to the northwest, a mixed evergreen forest is situated to the south, and active vineyard is situated to the east (Figure 1). The pond is fed by the adjacent seep and supplemented during the dry months with irrigation water. The pond contains koi fish and is protected with netting to reduce fish predation by wading birds and raccoons (Procyon lotor) (Figure 1).

Due to the disturbed nature of the grow site, special-status plants are not likely to occur. The field consists of non-native grassland species, such as wild oat (Avena fatua), Italian ryegrass (Festuca perennis), hedgehog dogtail (Cynosurus echinatus), bindweed (Convolvulus arvensis), and cultivated wheat (Triticum aestivum). A few ruderal forbs and shrubs have started to grow within the field and are present along the northern edge of the field near the koi pond. These species include coyote brush (Baccharis pilularis subsp. consanguinea), Italian thistle (Carduus pycnocephalus subsp. pycnocephalus), bull thistle (Cirsium vulgare), bristly ox-tongue (Helminthotheca echioides), white hayfield tarweed (Hemizonia congesta subsp. luzulifolia), mustard (Brassica sp.), lotus (Lotus sp.), Himalayan blackberry (Rubus armeniacus), and cultivated grape (Vitis sp.).

No trees occur within the grow site, but several tree are present within the adjacent riparian woodland and mixed evergreen forest, including valley oak (Quercus lobata), coast live oak (Q. agrifolia), Douglas fir (Pseudotsuga menziesii var. menziesii), madrone (Arbutus menziesii), and arroyo willow (Salix lasiolepis). A coast redwood (Sequoia sempervirens) is present near the seep to the northeast.

Grow Site B Grow Site B is situated adjacent to a dilapidated residence that is no longer occupied, planted trees, and a vineyard to the south, a seasonal wetland seep (different seep than the one at Grow Site A) to the southwest, a drainage and riparian woodland to the west, and a mixed evergreen forest to the north and east (Figure 2). The site used to be cultivated for farming purposes from the original homestead and had been cleared of vegetation for several years, but is currently dominated by Himalayan blackberry and coyote brush with scattered western poison-oak (Toxicodendron diversilobum) and non-native grasses and ruderal plants, such as fescue grass (Festuca sp.), knot hedge-parsley (Torilis arvensis), rose clover (Trifolium hirtum), and wild oat. Bracken fern (Pteridium

aquilinum var. pubescens) and bush lupine (Lupinus albifrons var. collinus) are present along the eastern end of the grow site.

The seasonal seep supports wetland species, such as horsetail (Equisetum arvense), Bolander's rush (Juncus bolander), Pacific rush (Juncus effusus subsp. pacificus), creeping wildrye (Elymus triticoides subsp. triticoides), carex (Sedgecommon sp.), Sonoma hedge-nettle (Stachys stricta), and junegrass (Koeleria macrantha).

No trees occur within the grow site, but several trees are present within the adjacent riparian woodland and mixed evergreen forest and near the old house, including planted tree of heaven (Ailanthus altissima), planted walnut (Juglans sp.), arroyo willow, coast live oak, valley oak, and Douglas fir.

Grow Site B will occur outside of the seasonal wetland seep and will not result in the removal of any trees.

Storage Container Site The proposed storage container site is situated within a small patch of annual grassland that is adjacent to an old residence and barn to the west, mixed evergreen forest to the south, mixed evergreen forest and riparian woodland and drainage channel to the north, shrubs and a seasonal wetland seep to the east, and vineyard to the southeast (Figure 2). The storage container site supports a disturbed annual grassland with ruderal species, dominated by chicory (Cichorium intybus), sheep sorrel (Rumex acetosella), wild oat, western poison-oak, coyote brush, and yellow starthistle.

The storage container site will occur outside of the seasonal wetland seep and will not result in the removal of the existing old structures or of any trees or riparian vegetation.

Wildlife Observations Wildlife observed during the field survey were species typical of rural landscapes, and consisted of western fence lizard (Sceloporus occidentalis), turkey vulture (Cathartes aura), California scrub-jay (Aphelocoma californica), California quail (Callipepla californica), Nuttall’s woodpecker (Picoides nuttallii), black phoebe (Sayornis nigra), western wood-pewee (Contopus sordidulus), spotted towhee (Pipilo maculatus), and dark-eyed junco (Junco hyemalis).

Evidence of prior nesting by a possible mourning dove (Zenaida macroura) was observed in the barn and evidence of a barn swallow (Hirundo rustica) or black phoebe nest was observed in the dilapidated residence adjacent to the barn near the storage container site. No evidence of roosting bats was observed in any of the adjacent structures during the survey.

Based on the former use of Grow Sites A and B and the storage container site, dominance of ruderal non-native vegetation, and their location within a previously planted vineyard, the sites are not likely to support populations of any special-status species. Additionally, the sites are not located within Critical Habitat for any federally listed species.

Special-status and other bird species could nest in the shrubs, trees, and structures adjacent to the sites and special-status and other bat species could roost in the structures adjacent to the sites. LSA recommends pre-construction surveys to be conducted on and adjacent to the sites to avoid potential impacts to nesting birds and roosting bats.

8/8/17 (P:\KKW1701\Lunar Ridge Farms Bio Assessment 8-7-17.docx) 7

Development of the cannabis farm and storage container could impact special-status and common nesting birds. If vegetation is removed or the cannabis plants and storage container are placed during the nesting season (February 1 to August 31), impacts to nesting birds could occur. Impacts to active bird nests would violate the Migratory Bird Treaty Act and California Fish and Game Code; such impacts would be considered significant unless mitigated. LSA recommends the following mitigation measure:

If vegetation removal is scheduled between February 1 and August 31, a qualified biologist will conduct a nest survey of the area where vegetation is to be removed within two weeks of the scheduled removal. If an active nest is found, a suitable buffer (depending on the nesting species and habitat) will be established around the nest site and a qualified biologist will monitor the nest at periodic intervals until the young have fledged or it has been determined that the nest has failed. After the monitoring biologist has determined that the nest site is inactive, clearing of vegetation and/or other construction activity can commence in the former buffer area.

The structures adjacent to the storage site and Grow Site B could support roosting bats. LSA recommends implementing the following mitigation measure prior to project development:

Prior to the vegetation removal and installation of the storage container, a qualified biologist will conduct a survey to determine if and how bats are using the adjacent structures. A qualified biologist will determine the species of bats present and the type of roost (i.e., day roost, night roost, maternity roost, hibernation site). If feasible, construction will occur beyond 50 feet from bat roosting sites and staging areas, construction equipment, and construction vehicles will be placed at least 50 feet from bat roosts. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service?

Riparian habitat is associated with riverine or stream systems, which are adjacent to but not present within the two grow sites or storage container site. The adjacent riparian habitat will not be affected by the proposed project because the grow sites and storage site are away from the edge of the riparian woodland. Besides the nearby seep and seasonal wetland seep, no other sensitive natural communities are on or adjacent to the two grow sites and storage site; therefore, the proposed project will not affect these resources. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?

The adjacent pond, seep, seasonal wetland seep, and drainage channels are potential federally protected wetlands; however, as noted above the three sites occur outside of these features. Although located nearby, the two grow sites and the storage container site do not support any federally protected wetlands.

8/8/17 (P:\KKW1701\Lunar Ridge Farms Bio Assessment 8-7-17.docx) 8

d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?

As noted previously, the two grow sites and storage container site are situated in disturbed areas located within a vineyard next to old farm and residence structures. Wildlife likely use the adjacent mixed evergreen forests and riparian woodlands for wildlife movement, but the disturbed habitat within the sites provides limited wildlife movement and species that currently move through the sites will likely continue to do so after project completion. None of the three sites are part of an established movement area for local or regional wildlife. Additionally, no wildlife nursery sites such as a heron rookery occur on any of the sites. Trees near the sites were inspected for evidence of heron rookeries (i.e., presence of nests) and none were found. Old, abandoned structures are adjacent to Grow Site B and the storage container site, but no evidence of bat maternity roosts was observed. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?

The proposed project is subject to the requirements of the Sonoma County General Plan 2020 including the Open Space and Resource Conservation Element: 3 Biotic Resources (August 2, 2016). The Biotic Resources Element contains provisions for the protection of special-status species, sensitive habitats including wetlands, wildlife corridors, and valley oaks. As discussed above, the three sites are not located within suitable habitat for special-status species, a riparian corridor, or habitat connectivity corridor. A pond, seep, and seasonal wetland seep occur near the sites, but the cannabis plants will be placed outside of the high water mark of the pond and seeps and outside of the riparian woodland habitat. Additionally, the project will not result in the removal of any trees and therefore would not conflict with the Sonoma County native and heritage tree protection ordinances.

f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan?

The grow sites and storage container site are not located within any Habitat Conservation or Natural Community Conservation Plan area, and are is not subject to any other approved local, regional, or State habitat conservation plan; therefore, the proposed project would not conflict with any such plan.

SUMMARY The proposed project sites are located within disturbed annual grassland or ruderal habitat within an active vineyard adjacent to old buildings, seeps, and riparian woodland and mixed evergreen forest habitat. Due to the lack of suitable habitat within the three sites, the proposed project will likely not adversely impact any special-status plant species, riparian habitat, or other sensitive natural community, wetlands, or wildlife movement corridors. The project will not conflict with any provisions of the Sonoma County General Plan concerning biotic resources. The project, however, could impact nesting birds and roosting bats if present during vegetation removal and installation of

the storage container. With implementation of the recommended mitigation measures, potential impacts to nesting birds and roosting bats would be avoided.

Natural Investigations Co. Page i WASTE MANAGEMENT PLANS

1.0 INTRODUCTION

This Solid Waste, Green Waste, and Wastewater Plan and Hazardous Materials Management Plan (“Plans”) have been prepared to fulfill the requirements of Sonoma County’s Commercial Cannabis Program (Ordinance No. 6189). The Ordinance states: “A Waste Management Plan addressing the storing, handling and disposing of all waste by-products of the cultivation and processing activities in compliance with the Best Management Practices issued by the Agricultural Commissioner shall be submitted for review and approval by the agency having jurisdiction. This plan shall characterize the volumes and types of waste generated, and the operational measures that are proposed to manage and dispose, or reuse, the wastes in compliance with the Best Management Practices and County standards.”

“All garbage and refuse on this site shall be accumulated or stored in non-absorbent, water-tight, vector resistant, durable, easily cleanable, galvanized metal or heavy plastic containers with tight fitting lids. No refuse container shall be filled beyond the capacity to completely close the lid. All garbage and refuse on this site shall not be accumulated or stored for more than seven calendar days, and shall be properly disposed of before the end of the seventh day in a manner prescribed by the Solid Waste Local Enforcement Agency. All waste, including but not limited to refuse, garbage, green waste and recyclables, must be disposed of in accordance with local and state codes, laws and regulations. All waste generated from cannabis operations must be properly stored and secured to prevent access from the public.”

“A waste water management plan shall be submitted identifying the amount of waste water, excess irrigation and domestic wastewater anticipated, as well as disposal. All cultivation operations shall comply with the Best Management Practices issued by the Agricultural Commissioner and shall submit verification of compliance with the Waste Discharge Requirements of the applicable Regional Water Quality Control Board, or waiver thereof. Excess irrigation water or effluent from cultivation activities shall be directed to sanitary sewer, septic, irrigation, greywater, or bio-retention treatment systems. If discharging to a septic system, a system capacity evaluation by a qualified sanitary engineer shall be included in the management plan. All domestic waste for employees shall be disposed of in a permanent sanitary sewer or on-site septic system demonstrated to have adequate capacity.

These Plans should be amended whenever there is a significant change in cultivation operations or whenever a pollution event occurs. 1.1. Project Location and Description The proposed cultivation operation is located on a 132.3-acre parcel at 4800 Cavedale Road, Glen Ellen, California (APN 053-051-038). The cultivation operation will consist of one outdoor garden approximately 19,000 square feet in size (see exhibits). The future cannabis garden will consist of approximately 800 to 1,200 plants. The garden will exist in an area previously cleared and will not require grading; the cultivation area was previously used for vineyard agriculture. There are no future construction plans for this cultivation operation, with the

Natural Investigations Co. Page 2 WASTE MANAGEMENT PLANS exception of a 6-foot tall security fence which will surround the garden. The cultivation method is aboveground fabric pots or plants in the native soil in in full-sun. Irrigation water will be supplied by an existing agricultural well. Mixing tanks (up to 1,000 gallons in storage) along the southeastern garden area will be used to dissolve fertilizers and other amendments into the irrigation water to create a compost tea. A 6,000 gallon water storage tank will be located adjacent to the mixing tanks. PVC pipes, black poly tubing, and driplines will be installed in the future to deliver the water and compost tea to each planting station. A waterline does not yet exist from the recently established agricultural well to the cultivation area, but will be constructed of underground PVC pipes installed along an existing access road. No materials or chemicals will be stored on site; any fertilizers / amendments used by the operation will be purchased as needed. A small amount of soil may be imported at the beginning of the first planting season, but no further soil importation or soil stockpiling will occur. Existing features on the parcel include several acres of certified organic vineyard agriculture (Korbin Kameron Wines), which will continue operation in addition to the cannabis cultivation operation. 1.2. Site Features The topography of the parcel is mountainous, with ridgelines, valleys, and rolling hills. The elevation ranges from 1,923 feet on the northwestern area of the parcel to 2,400 feet above sea level to the east. The elevation of the cultivation area ranges from 2,158 to 2,191 feet above sea level. Several intermittent stream are present throughout the parcel, which flow to the west toward Stuart Creek, which is a tributary to Sonoma Creek. There are no wetlands within the cultivation area. However, wetlands are present on the parcel. A freshwater pond wetland is located 250 feet to the south and riverine wetlands are present over 1,500 feet to the southeast. A small seep is also present 150 feet to the north-northeast of the garden, as well as a Class III Watercourse, over 50 feet to the west of the cultivation area.

3.0 SOLID WASTE MANAGEMENT PLAN

3.1. Goals The goals of this solid waste management plan are: x minimize the generation of solid waste and dispose of solid waste properly. x Provide an estimate of the type and amount of solid waste that will be generated on an annual basis. x Describe how mediums, plant waste, and material waste will be handled. x Describe how the permittee will minimize solid waste generation, including working with vendors to minimize packaging. x Describe how solid waste will be disposed 3.2. Waste Inventory The following are potential sources of solid waste that may be generated during cultivation operations: x growing medium waste: soil, soil amendments, mulch, humus, vermiculite, perlite, etc. x landscape maintenance: trimmings, treated lumber, fencing x irrigation system waste: black poly tubing, PVC pipes and fittings, hoses, mixing tanks, etc. x Cannabis processing waste: stems and root balls, etc. x packaging material from vendors: pallets, plastic bags, cloth bags, plastic jugs and buckets, etc. x trash from staff: food packaging, water bottles, toilet paper, etc. x septic waste (see Wastewater Management Plan). Volume of solid waste generated at this cultivation facility is estimated at 130 gallons / week (equivalent to two household 65-gallon roll-carts). 3.3. Material Handling and Waste Management The locations of waste bins / containers are shown in the Exhibits. Waste will be hauled to an appropriate licensed facility by a private waste hauling contractor, such as Republic Services, or by cultivation operation staff. Available facilities include the Central Disposal Site (Republic Services) at 500 Mecham Road, Petaluma. Republic Services of Sonoma County, Inc., also operates four smaller transfer stations, located in Annapolis, Guerneville, Healdsburg, and Sonoma.

Recyclables will be segregated from the solid waste and deposited in an appropriate recycling facility. Recyclables such as scrap metal, cardboard, glass, metal and plastic containers, and newspaper can be conveniently unloaded at a recycling drop-off center, such as the Central Disposal Site at 500 Mecham Road, Petaluma.

Yard waste, green waste, and other compostable materials will be segregated from the solid waste and shredded and composted onsite for reuse as mulch or as a soil amendment, or deposited at an appropriate transfer facility. Compost and recyclable wood can be dropped of at any Sonoma County Refuse Disposal Site where it is processed as new compost.

Natural Investigations Co. Page 5 WASTE MANAGEMENT PLANS

Household toxic materials will be segregated from the solid waste and disposed of at the Household Toxics Facility (Clean Harbors) at the Central Disposal Site at 500 Mecham Road, Petaluma.

The following material handling and waste management measures will be implemented: x Prevent or minimize handling of chemical/industrial materials or wastes that can be readily mobilized by contact with stormwater during a storm event; x Contain all stored non-solid chemical/industrial materials or wastes (e.g., particulates, powders, shredded paper, etc.) that can be transported or dispersed by the wind or contact with stormwater during handling; x Cover waste disposal containers and material storage containers that contain chemical/industrial materials when not in use; x Divert run-on and stormwater generated from within the facility away from all stockpiled materials; x Clean all spills of chemical/industrial materials or wastes that occur during handling in accordance with the spill response procedures); and x Observe and clean as appropriate, any outdoor material or waste handling equipment or containers that can be contaminated by contact with chemical/industrial materials or wastes. A sandbag barrier (Construction BMP SE-8) can be placed around storage areas to prevent stormwater run-on from adjacent upstream areas. Sheds or shipping containers may be used to store hand tools, small parts, and most cultivation materials that can be carried by hand. Very large items may be stored in the open in a general storage areas. Such materials should be elevated with pallets or cement blocks to minimize contact with stormwater. Spill clean-up materials, material safety data sheets, a material inventory, and emergency contact numbers will be maintained and stored in the residence or shipping container. However, this cultivation operation plans to purchase materials as needed and no storage on site will occur at this time. Unused materials may be stored in a storage container on the northerly adjacent parcel if necessary.

To reduce or eliminate pollution of storm water from stockpiles of soil and cultivation materials, stockpiles will be surrounded with sediment controls (Construction BMP SE-5: Fiber Rolls, SE- 8: Sandbag Barrier, and WM-3 Stockpile Management) as needed. Plastic covers will be used, as needed, before rain events or before strong winds begin. However, soil stockpiling is not planned on site at this time.

BMPs will be implemented to minimize storm water contact with waste materials and prevent waste discharges (Construction BMP WM-5 Solid Waste Management). Solid waste should be removed and disposed off-site at least weekly at a proper receiving facility. Any chemicals will be purchased as needed and will not be stored on site. Chemical wastes will be appropriately and clearly marked in containers and segregated from other non-waste materials.

Storage of soil amendments and chemicals will employ the following CASQA Industrial BMP fact sheets: x SC-31: Outdoor Liquid Container Storage

Natural Investigations Co. Page 6 WASTE MANAGEMENT PLANS

x SC-32: Outdoor Equipment Operations x SC-33: Outdoor Storage of Raw Materials x SC-34: Waste Handling and Disposal x SC-40: Contaminated or Erodible Surfaces x TC-30: Vegetated Swale x TC-31: Vegetated Buffer Strip. 3.4. Hazardous Materials and Wastes The County requires a Hazardous Materials Business Plan for the following volumes of hazardous materials: greater than 55 gallons of liquid; 200 standard cubic feet of compressed gas; or 500 pounds of a solid. All permittees shall manage all waste that is hazardous waste, as defined in Section 40141 of Public Resources Code, in compliance with all applicable hazardous-waste statutes and regulations.

The chemicals typically used at this cultivation operation are listed in the table below. No hazardous materials are currently used in this cultivation operation. Therefore, no hazardous wastes will be generated. Should hazardous materials be used, BMP WM-6: Hazardous Waste Management will be implemented to minimize storm water contact with hazardous materials and prevent waste discharges.

4.0 GREEN WASTE MANAGEMENT PLAN

4.1. Goals The goals of this green waste management plan are: x Describe how mediums, plant waste, and material waste will be handled. x Provide an estimate of the type and amount of cannabis vegetative waste that will be generated on an annual basis. x minimize the generation of green waste, and x Describe how green waste will be disposed x All commercial cannabis cultivation, cannabis nursery, and cannabis microbusinesses shall properly manage growing medium and dispose of growing medium properly. x All commercial cannabis cultivation, cannabis nursery, cannabis manufactures, cannabis distributor, and cannabis microbusinesses shall minimize the generation of cannabis vegetative waste and dispose of cannabis vegetative waste properly. 4.2. Sources of Green Waste Sources of green waste consist of the following: x growing medium wastes: soil, soil amendments, mulch, humus, vermiculite, perlite, etc. x landscape maintenance: lawn and weed trimmings, treated lumber, wood fencing, etc. x Cannabis processing waste: leaves, stems, and root balls that remain after flower harvest; and whole dead plants, etc. Volume of green waste generated by this cultivation operation is estimated at one cubic yard per month, or 12 cubic yards per year. 4.3. Handling and Disposal of Green Waste Non-cannabis green waste will be composted onsite. Cannabis green waste will either be composted onsite or disposed at a licensed landfill offsite after rendering it unconsumable.

Non-cannabis green waste will be shredded in a wood chipper, as necessary. Green waste will be mixed with soil and inoculated with humus. Compost heaps should be at least one cubic yard in size to generate and sustain necessary heat for composting (to sustain aerobic digestion). Compost heaps should be segregated into batches as they age, with humus being the resulting product after several weeks of composting. Compost heaps should be turned often to encourage aeration and aerobic digestion and supplemental water added to keep the heaps moist, but not wet (to discourage anaerobic digestion). Cannabis waste should be shredded and mixed with at least an equal amount of compostable materials such as food waste, yard waste, or growing medium (to render the cannabis unconsumable). Cannabis waste must be kept inside the locked fence or other locked compound at all times.

If cannabis waste is to be disposed offsite, it should first be shredded and blended with an equal part of non-consumable material, such as cardboard. Cannabis waste must be kept inside the locked fence or other locked compound until ready for transport. Once rendered unconsumable, cannabis waste can then be transported as solid waste to the proper disposal facility (see Solid Waste Management Plan).

2.0 PROJECT AND SITE DESCRIPTION

2.1. Project Location and Description The proposed Cannabis cultivation operation is located on a 132.3-acre parcel at 4800 Cavedale Road, Glen Ellen, California (APN 053-051-038). The cultivation operation will consist of one outdoor garden approximately 19,000 square feet in size (see exhibits). The Cannabis garden will consist of approximately 800 to 1,200 plants. The garden will exist in an area previously cleared and will not require grading; the cultivation area was previously used for vineyard agriculture. There are no future construction plans for this cultivation operation, with the exception of a 6-foot tall security fence which will surround the garden. The cultivation method is aboveground fabric pots or plants in the native soil in in full-sun. Irrigation water will be supplied by an existing agricultural well. Mixing tanks (up to 1,000 gallons in storage) along the southeastern garden area will be used to dissolve fertilizers and other amendments into the irrigation water to create a compost tea. A 6,000-gallon water storage tank will be located adjacent to the mixing tanks. PVC pipes, black poly tubing, and driplines will be installed in the future to deliver the water and compost tea to each planting station. A waterline does not yet exist from the recently established agricultural well to the cultivation area, but will be constructed of underground PVC pipes installed along an existing access road. No materials or chemicals will be stored on site; any fertilizers / amendments used by the operation will be purchased as needed. A small amount of soil may be imported at the beginning of the first planting season, but no further soil importation or soil stockpiling will occur. Existing features on the parcel include several acres of certified organic vineyard agriculture (Korbin Kameron Wines), which will continue operation in addition to the cannabis cultivation operation.

2.2. Site Features The topography of the parcel is mountainous, with ridgelines, valleys, and rolling hills. The elevation ranges from 1,923 feet on the northwestern area of the parcel to 2,400 feet above sea level to the east. The elevation of the cultivation area ranges from 2,158 to 2,191 feet above sea level. Several intermittent stream are present throughout the parcel, which flow to the west toward Stuart Creek, which is a tributary to Sonoma Creek. There are no wetlands within the cultivation area, however wetlands are present on the parcel. A freshwater pond wetland is located 250 feet to the south and riverine wetlands are present over 1,500 feet to the southeast. A small seep is also present 150 feet to the north-northeast of the garden, as well as a Class III Watercourse, over 50 feet to the west of the cultivation area. Sonoma Creek and its tributaries are protected under federal laws (e.g. Clean Water Act) and state laws (e.g. Porter-Cologne Act).

3.0 WASTE WATER MANAGEMENT 3.1. Goal According to the Ordinance, the wastewater management plan must have the following elements: • Describe how will you manage storm and waste water to prevent the movement of nutrients, sediment, and other contaminants either on site or sanitary sewer; • All cultivation shall comply with the Agricultural Commissioner’s BMPs; and • Applicant shall submit verification of compliance with waste discharge requirements of applicable regional water quality control board.

3.2. Existing Sanitary Disposal System The parcel does not have a septic system or leach field. The parcel will rent a portable toilet for cultivation facility staff.

3.3. Waste Discharge Other Than Sanitary Waste Note that this cultivation operation is compliant with waste discharge requirements. Individual permits (Waste Discharge Requirements) are issued for individual point source dischargers, as needed. This cultivation operation will not be discharging wastewater as a point source. No process water is needed, such as for hydroponics. Irrigation water will be applied at agronomic rates and will not produce runoff that exits the property. A stormwater protection plan has been implemented. Therefore, Waste Discharge Requirements are not required because there is no significant discharge.

There are no point source discharges that require individual permitting / waste discharge requirements. Potential non-point waste discharges consist primarily of sediment, nutrients, and pesticides. This cultivation operation is enrolling in the State Water Resources Control Board’s Order WQ 2017-0023-DWQ General Waste Discharge Requirements for Discharges of Waste Associated with Cannabis Cultivation Activities, and a Site Management Plan has been prepared for this cultivation operation (bound separately).

3.4. Water Conservation The potential for wastewater discharge will be minimized by reducing water consumption. Water conservation practices will be implemented, including a combination of the following: • selection of plant varieties that are suitable for the climate of the region • the use of driplines and emitters (instead of overhead spray irrigation) • mulching to reduce evaporation • modification of water application rates using data from soil moisture meters and weather monitoring • shutoff valves on hoses and water pipes • immediate repair of leaking or malfunctioning equipment • daily visual inspections Construction BMP Fact Sheet NS-1: Water Conservation Practices will be implemented to prevent discharges from water supply equipment. Water application rates will be minimized as

Implementation and location of BMPs are shown on the Water Pollution Control Drawings (WPCDs) in Attachment A. Narrative descriptions of BMPs to be used during the project are listed by category in each of the following sections. Attachment B includes a list of the fact sheets of all the BMPs selected for this project.

4.2.3. Existing (pre-construction) Control Measures The following are existing (pre-construction) control measures within the project site: vegetated buffers; mulch on disturbed soils; and gravel on access roads.

4.2.4. Nature of Fill Material and Existing Data Describing the Soil No known fill is present at the site. Fill is not required for leveling of the project areas. Soil and amendments will be imported for cultivation purposes on an as needed basis.

4.2.5. Erosion Control Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to prevent soil particles from detaching and becoming transported in storm water runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles. This project will incorporate erosion control measures required by the contract documents, and other measures selected by the stormwater manager. This project will implement the following practices for effective temporary and final erosion control during construction and cultivation: • Preserve existing vegetation where required and when feasible; • Apply temporary erosion control to remaining active and non-active areas and reapply as necessary to maintain effectiveness; • Implement erosion control prior to the defined rainy season and maintain temporary erosion control measures at regular intervals throughout the defined rainy season to control erosion; • Stabilize non-active areas as soon as feasible after the cessation of earth-moving activities; • Control erosion in concentrated flow paths by applying erosion control devices as required;

Natural Investigations Co. Page 8 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

• Apply seed, as needed, to areas deemed substantially complete by the stormwater manager during the defined rainy season; and • At completion of construction, apply permanent erosion control to all remaining disturbed soil areas. Sufficient erosion control materials should be maintained on-site to allow implementation of this Plan. This includes implementation requirements for active areas and non-active areas that require deployment before the onset of rain. Implementation and locations of temporary erosion control BMPs are shown on the WPCDs in Attachment A and/or described in this section. The BMP Consideration Checklist in the following table indicates the BMPs that were considered and those that were selected to control erosion on the project site.

Scheduling Scheduling (EC-1) is the development of a written plan that includes sequencing of activities and the implementation of BMPs. The purpose of EC-1, is to reduce the amount and duration of soil exposed to erosion by wind, rain, runoff and vehicle tracking and to perform BMPs in accordance with the planned schedule. Preservation of Existing Vegetation Carefully planned Preservation of Existing Vegetation (EC-2) minimizes the potential of removing plants that protect the soil from erosion. The best way to prevent erosion is to not

Natural Investigations Co. Page 9 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

disturb the land. To effectively save existing vegetation, no disturbances of any kind should be allowed within a defined area around the vegetation.

Straw Mulch Straw mulch (EC-6) consists of placing a uniform layer of straw and incorporating it into the soil with a studded roller or crimper, or anchoring it with a tackifier or stabilizing emulsion. Straw mulch may be used throughout the disturbed areas adjacent to excavations and on shallow slopes surrounding the site.

Earth Dikes/Drainage Swales Several drainage swales exist on the project site. BMP EC-9: Earth Dikes and Drainage Swales will be used to maintain and monitor these facilities.

4.2.6. Sediment Control Sediment controls are structural measures that are intended to complement and enhance the selected erosion control measures and reduce sediment discharges from active construction areas. Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water. This project will incorporate sediment control measures required by the contract documents, and other measures selected by the stormwater manager.

Implementation and locations of sediment control BMPs are shown on the WPCDs in Attachment A. The BMP Consideration Checklist in the following table indicates the BMPs that were considered and those that were selected to control sediment on the project site.

Implementation of Temporary Sediment Controls Temporary sediment control BMPs will be deployed according to the schedule. During the rainy season, temporary sediment controls will be implemented at the draining perimeter of disturbed soil areas, at the toe of slopes, and at outfall areas at all times. During the non-rainy season, temporary sediment controls will be implemented at the draining perimeter of disturbed soil areas and at storm drain downstream from disturbed areas before rain events. During the non-rainy season, in the event of a predicted storm, the following temporary sediment control materials will be maintained on-site: silt fence, and fiber rolls.

4.2.7. Tracking Control The cultivation operation is accessed via a gravel and dirt access road which spans 0.5 miles from Cavedale Road. The following BMPs have been selected to reduce sediment tracking from the project site on to private or public roads: • TC-1: Stabilized Construction Entrance/Exit; and • TC-2: Stabilized Construction Roadway.

Stabilized Construction Entrance/Exit A stabilized project entrance/exit may be constructed and maintained at the entrance. The site entrance/exit will be stabilized to reduce tracking of sediment as a result of project traffic.

Natural Investigations Co. Page 11 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

Stabilization material commonly consists of 3 to 6-inch crushed stone aggregate. The entrance will be flared where it meets the existing road to provide an adequate turning radius.

Stabilized Construction Roadway The roadway through the site may also be designated and stabilized to prevent erosion and to control tracking of mud and soil material onto adjacent roads. The roadway should be clearly marked for limited speed to control dust. Refer to the WPCDs for entrance/exit and project roadway locations. Stabilization material commonly consists of 3 to 6-inch crushed stone aggregate.

4.2.8. Wind Erosion Control The following BMPs have been selected to control dust from the project site: • WE-1: Wind Erosion Control; • NS-1: Water Conservation Practices; and • WM-3: Stockpile Management.

Dust Control Potable water may be applied to disturbed soil areas of the project site to control dust and maintain optimum moisture levels for compaction. The water can be applied using water trucks. Water applications will be concentrated during the late summer and early fall months, when soils have the lowest moisture content or when winds are severe. BMPs WE-1: Wind Erosion Control and NS-1: Water Conservation Practices will be implemented to provide dust control and prevent discharges from dust control activities and water supply equipment. Water application rates will be minimized as necessary to prevent runoff and ponding and water equipment leaks will be repaired immediately. During windy conditions (forecast or actual wind conditions of approximately 25 miles per hour or greater), dust control will be applied to disturbed areas, including haul roads, to adequately control wind erosion. BMP WM-3: Stockpile Management will be implemented using silt fences and plastic covers to prevent wind dispersal of sediment from stockpiles.

4.2.9. Non-Storm Water Control An inventory of project activities and potential non-storm water discharges was provided previously. The BMP Consideration Checklist in Table 3-4 indicates the BMPs that were considered and those that were selected to control non-storm water pollution on the project site. Implementation and locations of some non-storm water control BMPs are shown on the Water Pollution Control Drawings in Attachment A. A narrative description of each BMP follows.

Water Conservation Practices BMP NS-1: Water Conservation Practices will be utilized to reduce or eliminate non- stormwater discharges. Irrigation systems and other water equipment will be kept in good working condition. Water leaks will be repaired promptly. Construction water runoff will be directed to areas where it can soak into the ground or be collected and reused.

Illicit Connection/Illegal Discharge Detection and Reporting The site manager and stormwater manager will implement BMP NS-6: Illicit Connection/Illegal Discharge Detection and Reporting throughout the duration of the project. Detection and

Natural Investigations Co. Page 13 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

reporting is applicable anytime illicit connection and illegal discharge is discovered or illegally dumped material is found on the project site.

Potable Water/Irrigation The site manager and stormwater manager will implement BMP NS-7: Potable Water/Irrigation, which consists of practices and procedures to manage discharge of potential pollutants. Irrigated areas will be inspected for overwatering, erosion and discharge. Water sources will be shut off as soon as possible following discovery of broken lines, sprinklers or valves. Water from off-site sources will be directed around the cultivation operation, where possible.

Vehicle and Equipment Operations Several types of vehicles and equipment may be used on-site throughout the project, including trucks, tractors, and tillers. BMPs NS-8; Vehicle and Equipment Cleaning, NS-9: Vehicle and Equipment Fueling, and NS-10: Vehicle and Equipment Maintenance will be utilized to prevent discharges of fuel and other vehicle fluids. Vehicle cleaning should not be performed on-site. All self-propelled vehicles should be fueled off site. If they are fueled by mobile fuel trucks, fuel trucks will each be equipped with absorbent spill clean-up materials. Drip pans will be used for all mobile fueling. Drip pans or absorbent pads will be used for all vehicle and equipment maintenance activities that involve grease, oil, solvents, or other vehicle fluids. All vehicle maintenance and mobile fueling operations will be conducted at least 50 feet away from operational inlets and drainage facilities and on a level graded area. However, no fueling or vehicle maintenance is planned on site at this time.

4.2.10. Waste Management and Materials Pollution Control An inventory of project activities, materials, and wastes was provided previously. The BMP Consideration Checklist in Table 3-5 indicates the BMPs that were considered and those that were selected to control project site wastes and materials. Implementation and locations of some materials handling and waste management BMPs are shown on the WPCDs in Attachment A. A narrative description of each BMP follows.

Material Delivery, Storage, and Use In general, BMPs WM-1 and WM-2 will be implemented to help prevent discharges of materials during delivery, storage, and use. A sandbag barrier (BMP SE-8) may be provided around the storage area to prevent run-on from adjacent areas. Watertight shipping containers may be used to store hand tools, small parts, and most materials that can be carried by hand, such as paint cans, solvents and grease. Very large items may be stored in the open in the general storage area. Such materials will be elevated with wood blocks to minimize contact with run-on. Spill clean-up materials, material safety data sheets, a material inventory, and emergency contact numbers will be maintained and stored in the southern shipping container.

Stockpile Management BMP WM-3: Stockpile Management, will be implemented to reduce or eliminate pollution of storm water from stockpiles of soil and other materials. Stockpiles will be surrounded with sediment controls (SE-5: Fiber Rolls or SE-8: Sandbag Barrier) as needed. Plastic covers (EC-7: Geotextiles & Mats) may also be used. However, soil stockpiling is not planned for this operation at this time.

Natural Investigations Co. Page 15 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

Spill Prevention and Control BMP WM-4: Spill Prevention and Control, will be implemented to contain and clean-up spills and prevent material discharges to the storm drain system. Spill prevention is also discussed above under Material Delivery, Storage, and Use and below under Waste Management.

Waste Management BMP WM-5: Solid Waste Management and BMP WM-6: Hazardous Waste Management will be implemented to minimize storm water contact with waste materials and prevent waste discharges. Solid wastes will be loaded directly into trucks or roll-off dumpsters for off-site disposal. When on-site storage is necessary, solid wastes will be stored in watertight dumpsters in the general storage area of the contractor’s yard. A licensed subcontractor will provide solid waste disposal services. Hazardous wastes will be stored in the shipping containers or covered containment area discussed above for materials storage. Hazardous wastes will be appropriately and clearly marked in containers and segregated from other non- waste materials.

Sanitary and Septic Wastes The site manager will implement BMP WM-9: Sanitary and Septic Waste Management and portable toilets will be located and maintained at the project site for the duration of the project. Regular maintenance will be provided by a licensed contractor and wastes will be disposed off- site. The toilets will be located away from concentrated flow paths and traffic flow.

4.3. BMP Maintenance, Inspection, and Repair All inspection, maintenance repair, and sampling activities should be performed by qualified personnel. The site manager or storm water manager may delegate any or all of these activities to an employee appropriately trained to do the task(s).

4.3.11. Implementation of Erosion Control BMPs BMPs will be deployed in a sequence to follow the progress of grading and construction, or tilling / cultivation. As the locations of soil disturbance change, erosion and sedimentation controls will be adjusted accordingly to control storm water runoff at the downgrade perimeter and drain inlets. BMPs will be mobilized as follows: • Year-round: o The site manager or stormwater manager will monitor weather using National Weather Service reports to track conditions and alert crews to the onset of rainfall events. o Disturbed soil areas will be stabilized with temporary erosion control or with permanent erosion control as soon as possible after grading or construction is complete. • During the rainy season: o Disturbed areas will be stabilized with temporary or permanent erosion control before rain events. o Disturbed areas that are substantially complete will be stabilized with permanent erosion control (soil stabilization) and vegetation (if within seeding window for seed establishment). o Prior to forecast storm events, temporary erosion control BMPs will be deployed and inspected. • During the non-rainy season:

Natural Investigations Co. Page 16 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

o The project schedule will sequence earth-moving activities with the installation of both erosion control and sediment control measures. The schedule will be arranged as much as practicable to leave existing vegetation undisturbed until immediately prior to grading. Sufficient quantities of temporary sediment control materials will be maintained on-site throughout the duration of the project, to allow implementation of temporary sediment controls in the event of predicted rain, and for rapid response to failures or emergencies. This includes implementation requirements for active areas and non-active areas before the onset of rain.

The site manager and stormwater manager shall use the guidelines in Table 4-6 for maintenance, inspection, and repair of BMPs.

4.5. Post-Construction Storm Water Management

4.5.1. Post-Construction Control Practices The following are the post-construction BMPs that are to be used at this project site after all construction is complete: vegetative buffers; water conservation and drip irrigation; and armored roads.

4.6. Training A copy of the Plan will be made available to the site personnel or contractor representatives engaged in the maintenance or installation of BMPs. Site inspectors observing pollution caused by ineffective construction or cultivation practices will inform site personnel of appropriate and proper erosion and sedimentation control practices, along with special follow- up inspection for further training. The Stormwater Manager or general contractor shall organize orientation sessions with all installation, inspection and maintenance personnel upon initiation of a specific project activity or change in key personnel. These sessions will be setup to ensure that all contractor and sub-contractor operations are implemented in accordance with this Plan. Training sessions will be included as part of regular safety meetings to familiarize works with the requirements of the Plan. 5.0 PROJECT SITE MONITORING PROGRAM 5.1. Objectives The Project Site Monitoring Program shall be developed and implemented to address the following objectives: • To demonstrate that the site is in compliance with all permits and ordinances; • To determine whether non-visible pollutants are present at the project site and are causing or contributing to exceedances of water quality objectives; • To determine whether immediate corrective actions, additional BMP implementation, or Plan revisions are necessary to reduce pollutants in storm water discharges and authorized non-storm water discharges; and • To determine whether BMPs indicated in the Plan are effective in preventing or reducing pollutants in storm water discharges and authorized non-storm water discharges.

5.2. Types of Inspections and Frequency Based on the project site’s location, construction / cultivation periods, and rainfall erosivity factor, this project should perform inspections at the following times: beginning of the rain season; before and after any storm that produces over 1 inch of rain; and during any storm that produces a stormwater discharge. Each inspection event will be logged in the Inspection Log in Attachment C.

5.2.1. Exceptions The inspectors shall be prepared to collect samples and conduct visual inspections. Inspectors are not required to physically collect samples or conduct visual inspections under the following conditions: • During dangerous weather conditions such as flooding and electrical storms; and • Outside of scheduled site business hours.

Natural Investigations Co. Page 18 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

5.2.2. Inspection and Sampling Personnel All inspection and sampling activities should be performed by the stormwater manager until site personnel are properly trained to take over these tasks. The name(s) and contact number(s) of the assigned inspection and sampling personnel are: • Korbin Ming o [email protected] • Daniel Leuck o (707) 934-7212 5.3. Record Keeping and Reports The site manager or storm water manager should retain records of all storm water monitoring information and copies of all reports for a period of at least three years. Each inspection event can be logged in the Inspection Log in Attachment C. These records include: • The date, place, time of facility inspections, sampling, visual inspections, and/or measurements, including precipitation; • The individual(s) who performed the facility inspections, sampling, visual inspections, and or measurements; • The date and approximate time of analyses; • The individual(s) who performed the analyses; • Rain gauge readings from site inspections; • Non-storm water discharge inspections and visual inspections and storm water discharge visual observation records; • Visual observation and sample collection exception records; and • The records of any corrective actions and follow-up activities that resulted from analytical results, visual inspections, or inspections.

5.4. Visual Inspection Plan The inspector should conduct visual observations (inspections) during business hours only. The inspector should record the time, date and rain gauge reading of all qualifying rain events. Within 2 business days (48 hours) prior to major rain events, the inspector should visually observe (inspect): • All storm water drainage areas to identify any spills, leaks, or uncontrolled pollutant sources (if needed, the site manager should implement appropriate corrective actions); • All BMPs to identify whether they have been properly implemented in accordance with the Plan (if needed, the site manager shall implement appropriate corrective actions); and • Any storm water storage and containment areas to detect leaks and ensure maintenance of adequate freeboard.

The inspector should conduct during-rain event visual observations (inspections) at regular intervals during extended storm events. The inspector shall visually observe (inspect) storm water discharges at all discharge locations.

Within two business days (48 hours) after major rain events, the inspector should conduct post rain event visual observations (inspections) to (1) identify whether BMPs were adequately designed, implemented, and effective, and (2) identify additional BMPs and revise the Plan accordingly.

Natural Investigations Co. Page 19 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

For the visual inspections described above, the inspector shall observe the presence or absence of floating and suspended materials, a sheen on the surface, discolorations, turbidity, odors, and source(s) of any observed pollutants. The inspector should maintain on-site records of all visual observations (inspections), personnel performing the observations, observation dates, weather conditions, locations observed, and corrective actions taken in response to the observations.

5.4.3. Non-Storm Water Discharge Monitoring Requirements The following visual monitoring requirements apply to the project: • The inspector shall visually observe (inspect) each drainage area for the presence of (or indications of prior) unauthorized and authorized non-storm water discharges and their sources. • The inspector shall conduct one visual inspection quarterly in each of the following periods: January-March, April-June, July-September, and October-December. • The inspector shall ensure that visual inspections document the presence or evidence of any non-stormwater discharge (authorized or unauthorized), pollutant characteristics (floating and suspended material, sheen, discoloration, turbidity, odor, etc.), and source. The inspector shall maintain on-site records indicating the personnel performing the visual inspections, the dates and approximate time each drainage area and non-storm water discharge was observed, and the response taken to eliminate unauthorized non-storm water discharges and to reduce or prevent pollutants from contacting non-storm water discharges.

5.5. Sampling Plan for Pollutants The inspector should analyze one or more effluent samples for any parameters indicating the presence of pollutants during any breach, malfunction, leakage, or spill observed during a visual inspection which could result in the discharge of pollutants to surface waters that would not be visually detectable in storm water. Samples of discharge will be collected at the designated sampling locations shown on the WPCDs for observed breaches, malfunctions, leakages, spills, operational areas, soil amendment application areas, and historical site usage areas that triggered the sampling event. Sampling locations are shown in the WPCDs in Attachment A.

The inspector should analyze samples for all applicable pollutant parameters. The inspector shall collect a sample of storm water that has not come in contact with the disturbed soil or the materials stored or used on-site (uncontaminated sample) for comparison with the discharge sample. The inspector shall compare the uncontaminated sample to the samples of discharge using field analysis or through laboratory analysis. The inspector shall keep all field /or analytical data. Samples will be analyzed for the applicable constituents using the USEPA analytical methods.

5.6. General Sampling Methodology

5.6.1. Sample Collection and Delivery The storm water manager shall designate and train personnel to collect, maintain, and ship samples in accordance with the Surface Water Ambient Monitoring Program’s 2008 Quality

Natural Investigations Co. Page 20 STORMWATER MANAGEMENT / EROSION CONTROL PLAN

Assurance Program Plan. The storm water manager shall ensure that testing laboratories will receive samples within 48 hours of the physical sampling (unless otherwise required by the laboratory), and shall use only the sample containers provided by the laboratory to collect and store samples.

The storm water manager shall ensure that all sampling and sample preservation are in accordance with the current edition of "Standard Methods for the Examination of Water and Wastewater" (American Public Health Association). All monitoring instruments and equipment (including a discharger’s own field instruments for measuring pH and turbidity) should be calibrated and maintained in accordance with manufacturers' specifications to ensure accurate measurements. The storm water manager shall ensure that all laboratory analyses are conducted according to test procedures under 40 Code of Federal Regulations Part 136, unless other test procedures have been specified in this General Permit or by the Regional Water Board. With the exception of field analysis conducted by the inspectors for turbidity and pH, all analyses should be sent to and conducted at a laboratory certified for such analyses by the State Department of Health Services.

An adequate stock of monitoring supplies and equipment for monitoring non-visible pollutants should be available on the project site prior to a sampling event. Monitoring supplies and equipment will be stored in a cool-temperature environment that will not come into contact with rain or direct sunlight. Sampling personnel should be available to collect samples in accordance with the sampling schedule. Supplies maintained at the project site will include, but are not limited to, surgical gloves, sample collection equipment, coolers, appropriate number and volume of sample bottles, identification labels, re-sealable storage bags, paper towels, personal rain gear, ice, Sampling Activity Log forms, and Chain of Custody (COC) forms. The storm water manager will obtain and maintain the field-testing instruments for analyzing samples in the field by trained sampling personnel.

Grab samples will be collected and preserved in accordance with the applicable test method. Only personnel trained in proper water quality sampling will collect samples. Samples will be collected by placing a separate lab-provided sample container directly into a stream of water down gradient and within close proximity to the potential non-visible pollutant discharge location. This separate lab-provided sample container will be used to collect water, which will be transferred to sample bottles for laboratory analysis. The up gradient and uncontaminated background samples shall be collected first prior to collecting the down gradient to minimize cross-contamination. The sampling personnel will collect the water upgradient of where they are standing. Once the separate lab-provided sample container is filled, the water sample will be poured directly into sample bottles provided by the laboratory for the analyte(s) being monitored. To maintain sample integrity and prevent cross-contamination, sampling collection personnel will: • Wear a clean pair of surgical gloves prior to the collection and handling of each sample at each location; • Not contaminate the inside of the sample bottle by not allowing it to come into contact with any material other than the water sample; • Discard sample bottles or sample lids that have been dropped onto the ground prior to sample collection;

• Not leave the cooler lid open for an extended period of time once samples are placed inside; • Not sample near a running vehicle where exhaust fumes may impact the sample; • Not touch the exposed end of a sampling tube, if applicable; • Avoid allowing rainwater to drip from rain gear or other surfaces into sample bottles; • Not eat, smoke, or drink during sample collection; • Not sneeze or cough in the direction of an open sample bottle; • Minimize the exposure of the samples to direct sunlight, as sunlight may cause biochemical transformation of the sample to take place; • Decontaminate sampling equipment prior to sample collection using a laboratory-grade soapy water wash, distilled water rinse, and final rinse with distilled water; and • Dispose of decontamination water/soaps appropriately; i.e., not discharge to the storm drain system or receiving water.

Immediately following collection, samples for field analysis will be tested in accordance with the field instrument manufacturer’s instructions and results recorded on the Sampling Activity Log. Immediately following collection, sample bottles for laboratory analytical testing will be capped, labeled, documented on a COC form provided by the analytical laboratory, sealed in a re-sealable storage bag, placed in an ice-chilled cooler, at as near to 4 degrees Celsius as practicable, and delivered within 24 hours to a California state-certified laboratory.
