Phase I Environmental Site Assessment TUSCAN RIDGE PROPERTY WKA No.12206.04 EXECUTIVE SUMMARY The purpose of this Phase I Environmental Site Assessment (ESA) was to assess the Tuscan Ridge Property (herein referred to as Site)for evidence of Recognized Environmental Conditions (RECs)resulting from current and/or former Site activities.The Site is located in Paradise, California (Figures 1, 2, 3, and 4)and is comprised of 175 acres of land that was formerly developed with a golf course and has been setup with a basecamp for the emergency response efforts for the Camp Fire. The Site is identified by two Butte County Assessor’s Parcel Numbers (APNs): 040-520-100 and -103 (Figure 3).The following presents a list of observations and findings identified during the preparation of this report: The historical land use research dating back to the late 1800s revealed that the Site was vacant land from at least 1891 to at least 1998. Railroad tracks were present on the southern portion of the Site by 1941.The Site was developed with a golf course, with three structures on the southeastern portion, by 2006. In December 2018, the Site was graded and aggregate base was spread across the majority for the development of an emergency basecamp for Pacific Gas &Electric (PG&E)and other contractors responding to areas impacted by the Camp Fire. During a visit to the property on January 2, 2019, WKA observed a mobile fueling area on the central portion of the Site. WKA observed stained soils in the vicinity of mobile fuel trucks.Subsequent site inspections were conducted on February 15, 2019, and April 9, 2020. Site inspection reports for the subsequent visits describe that the mobile fuel area was re-graded by February 15, 2019, and that PG&E had reportedly excavated diesel impacted soil to bedrock and disposed of it off-site. During a visit to the property on January 18, 2019, WKA observed two aboveground storage tanks (ASTs) on the southeastern portion of the Site. WKA was not provided additional information regarding the ASTs. During a visit to the property on April 9, 2020, WKA observed that the Site was no longer being used as a basecamp. The two ASTs observed in January 2019 remained on the property. WKA observed that the majority of the Site’s surface had been graded with gravel. WKA observed two lined ponds on the southern portion of the Site. WKA also observed a series of green, PVC pipes protruding vertically from the ground on the southwest portion of the Site. The pipes are associated with a new septic system that has been installed at the Site. Phase I Environmental Site Assessment Page ii3100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 Given the age of development on the Site, it is unlikely that asbestos containing building materials and lead-based paints were used in the construction and/or maintenance of the Site buildings. Given the documentation reviewed concerning the agency listings for neighboring facilities, none of the facilities reviewed is likely to have a negative impact on the Site. Based on the completion of the vapor encroachment condition (VEC) screening matrix, WKA concludes a VEC can be ruled out because a VEC does not or is not likely to exist. WKA has performed this ESA in conformance with the scope and limitations of ASTM Standard Practice E 1527-13 for the Tuscan Ridge Property. This assessment has revealed no RECs in connection with the Site except the following: On-site concerns were noted from the presence of railroad tracks along the southern property boundary by at least 1941. On-site concerns were noted from the two ASTs located on the southeastern portion of the Site. Phase I Environmental Site Assessment TUSCAN RIDGE PROPERTY WKA No.12206.04 1.0 INTRODUCTION 1.1 Purpose The purpose of this Phase I Environmental Site Assessment (ESA) was to evaluate the Tuscan Ridge Property (herein referred to as Site)for evidence of potential Recognized Environmental Conditions (RECs) resulting from current and/or former site activities as defined by the American Society of Testing and Materials (ASTM) Standard E 1527-13 (ASTM, 2013). According to the ASTM, “this practice is intended to permit a user to satisfy one of the requirements to qualify for the innocent landowner,contiguous property owner, or bona fide prospective purchaser limitations under CERCLA [Comprehensive Environmental Response, Compensation and Liability Act] liability (hereinafter, the “landowner liability protections,” or “LLPs”): that is, the practice that constitutes “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined at 42 U.S.C. §9601(35)(B).” This ESA has been performed in general conformance with the ASTM Standard E 1527-13 and the scope and limitations defined in Wallace-Kuhl & Associates (WKA)proposal, 3PR18254, dated December 20,2018. 1.2 Scope of Services WKA has completed this ESA for the Site shown on Figures 1 through 4.Mr. Scott Bates with Tuscan Ridge Associates, LLC authorized WKA to proceed with this assessment on January 7, 2019,through a signed WKA Environmental Site Assessment Consulting Agreement.

Phase I Environmental Site Assessment Page 33100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 1.4 User Provided Information WKA provided Tuscan Ridge Associates, LLC a copy of the User Questionnaire and the Helpful Documents checklist.Mr.E.M. West,Tuscan Ridge Associates, LLC, completed and returned the documents to WKA. Discussion regarding his responses is provided in the following section. A copy of the completed questionnaire is included in Appendix B. In summary, Mr.West was not aware of any records of environmental liens or AULs currently recorded against the Site. Mr.West stated he does not possess specialized knowledge or experience related to the Site. Mr.West stated that he is not aware of any obvious indicators that point to the presence or likely presence of contamination at the Site. Mr.West was not aware of existing “Helpful Documents” as defined in Section 10.8.1 of the ASTM Standard as noted on the “Helpful Documents Checklist” included in Appendix B. Phase I Environmental Site Assessment Page 43100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 2.0 SITE DESCRIPTION 2.1 Site and Vicinity General Characteristics The Site is located at 3100 Skyway in Paradise, California (Figures 1 and 2). The Site is comprised of two Butte County Assessor’s Parcel Numbers (APNs): 040-520-100 and -103, totaling 175 acres of land that was formerly developed with a golf course and has been setup with a basecamp for the emergency response efforts for the Camp Fire (Figure 3). Surrounding land use consisted of a gun range and vacant land (Figure 4). The Site was developed with three structures by 2006.Given the age of the existing development on the Site, it is unlikely that asbestos containing building materials and lead- based paints were used in the construction and/or maintenance of the Site building. 2.2 Site Reconnaissance A visual site reconnaissance for the Phase I ESA was conducted by WKA on January 2 and 18, 2019.As tenants vacated the Site, WKA conducted additional site visits on February 15, 2019, and April 9, 2020.Copies of letters regarding the subsequent site visits are provided in Appendix E.Figures 5a through 5d provide color photographs of the Site taken during the site visits. On January 2, 2019, the Site had been developed with an emergency basecamp for PG&E and subcontractors that were responding to the vicinity after the Camp Fire.Multiple sleeper trailers, recreational vehicles, and temporary office buildings were parked on the southern portion of the Site. WKA observed several pallets of 55-gallon drums labeled as “used grease” in the vicinity of a tent being used as a mobile kitchen.The pallet and drums were covered by a blue tarp. WKA observed two, empty 55-gallon drums and two, empty 20-gallon empty drums that were pre-labeled to indicate that hazardous materials should be disposed in them. WKA observed a large parking areas to the north of the trailers and buildings. The central portion of the Site was being held materials used for repairs in areas destroyed by the Camp Fire.WKA observed a mobile fueling station on the central portion of the Site. Two fuel trucks were parked in a designated area. WKA observed tarps beneath the fuel trucks; however, significant staining was noted around the tarps. WKA observed an empty 55-gallon drum labeled as “oily debris” in the vicinity of the fuel trucks.Subsequent site inspections are recorded for February 15, 2019, and April 9, 2020. These site inspection reports show that the mobile fuel area was re-graded by February 15, 2019 and that PG&E had reportedly excavated diesel impacted soil to bedrock and disposed of it off-site. (Personal Communication Scott Bates, 2019)WKA observed a truck wash on the west-central portion of the Site. WKA observed a lined area filled with water Phase I Environmental Site Assessment Page 53100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 beneath the truck wash. WKA observed light towers with generators stationed throughout the Site. The majority of light towers had a small containment pan beneath them. On January 18, 2019, WKA returned to the Site. WKA noted that the basecamp operations had decreased since the previous visit. WKA observed two aboveground storage tanks on the southeastern portion of the Site near a pond. On April 9, 2020, WKA returned the Site. In April 2020, the Site was no longer being used as a basecamp. WKA observed the majority of the Site’s surface had been graded with gravel. WKA observed two lined ponds on the southern portion of the Site. WKA observed green, PVC pipes protruding vertically from the ground on the southwestern portion of the Site, associated with a new septic system. The two aboveground storage tanks that were previously observed on the Site remained. WKA observed the storage of miscellaneous equipment and parts on the northwestern portion of the Site associated with trenching activities that were conducted with infrastructure development. A metal-sided, Quonset-type hut is located on the eastern portion. The Quonset-type hut was vacant during the April 2020 visit. 2.2.1 Municipal Infrastructure and Utilities Electricity was provided by on-site generators in 2019; however, a Pacific Gas & Electric line has been installed at the Site and will now provide electricity.Natural gas is provided by Amerigas. Sanitary waste is discharged to a large set of septic tanks then dispersed to a lined aerobic leach field system then pumped into two lined waste water ponds for evaporation.. Potable water is provided by the Tuscan Ridge Golf Club public water system.Two aboveground fuel storage tanks are located on the southeastern portion of the Site. 2.3 Adjoining Properties The Site is bounded to the north by Skyway followed by vacant land. The Paradise Rod and Gun Club and vacant land are located to the east of the Site. Vacant land is located to the south and west of the Site. Phase I Environmental Site Assessment Page 63100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 3.0 INTERVIEWS Interviews with various persons familiar with the site vicinity, including representatives of public agencies, were conducted for the purpose of identifying past and present uses, which may have contributed to RECs on the Site. Results of those interviews are discussed in the following sections. 3.1 Owner or Key Site Manager Mr. E.M. West, Tuscan Ridge Associates, LLC,completed a questionnaire regarding the Site. According to Mr. West, Tuscan Ridge Associates, LLC, has owned the Site since November 2005. He stated that the Site has been used for grazing and a golf course. Mr. West indicated that a clubhouse was constructed on the Site as part of the golf course.He said that the Site is currently being used as a PG&E basecamp for fire restoration efforts.According to Mr. West, approximately 500 cubic yards of soil from a CalTrans project that was located at Highway 32 and Highway 99 was placed on the Site in approximately 2006.The soil was spread just east of the maintenance yard.Mr. West indicated that there is one septic tank on the Site. He stated that potable water is provided by the Tuscan Ridge Golf Club Public Water System.Mr. West is not aware of any environmental liens that have been recorded for the Site. In April 2020, Mr. West provided updated information for the Site. He stated that wastewater storage ponds were constructed on the Site in 2019. He stated that underground storage tank containing waste water were installed as part of a wastewater treatment plant. Mr. West did not indicate any other significant changes to the Site. 3.2 Occupants (Multi-family or Major) No occupants were interviewed during the preparation of the Phase I ESA. 3.3 Past and Present Owners, Operators, and/or Occupants No information regarding past owners was received by WKA during completion of this report. 3.4 State and/or Local Government Officials WKA searched the State Water Resources Control Board (SWRCB) GeoTracker website and the Department of Toxic Substances Control (DTSC) EnviroStor website for facilities in the vicinity of the Site.No additional facilities were located. Phase I Environmental Site Assessment Page 73100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 3.5 Abandoned Properties As referenced in 40 CFR Part 312, in the case of inquiries conducted at “abandoned properties,” as defined in §312.23(d), “where there is evidence of potential unauthorized uses of the Site or evidence of uncontrolled access to the Site, the environmental professional’s inquiry must include interviewing one or more (as necessary) owners or occupants of neighboring or nearby properties from which it appears possible to have observed uses of, or releases at, such abandoned properties…” No evidence of potential unauthorized uses, or evidence of uncontrolled access to the Site was observed. The Site is not considered an abandoned property and therefore, WKA did not interview owners or occupants of neighboring properties. Phase I Environmental Site Assessment Page 83100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 4.0 RECORDS REVIEW The purpose of the records review is to obtain and review information concerning the current and historical use of the Site and adjoining properties that would help identify the presence of RECs in connection with the Site. The records review included review and discussion of the following, as available: Physical Setting Source(s); Historical Use Information; and, Environmental Record Sources. 4.1 Physical Setting Source(s) The Site is depicted on the 2012 United States Geological Survey (USGS) 7.5 Minute topographic map of the Hamlin Canyon, California Quadrangle as undeveloped land. The Site is located within Sections 1 and 2, Township 21 North, Range 2 East and Sections 35 and 36, Township 22 N Range 2 E, Mount Diablo Base and Meridian, at an elevation between +640 and 920 feet relative to mean sea level (msl). 4.1.1 Regional and Local Geology The Site is located on the boundary between the Great Valley and Sierra Nevada geomorphic provinces. The Great Valley of California geomorphic province, a 500-mile, northwest-trending structural trough,is generally constrained to the west by the Coast Ranges and to the east by the foothills of the Sierra Nevada Range (Norris and Webb, 1990).The Great Valley consists of two valleys lying end-to-end, with the Sacramento Valley to the north and the San Joaquin Valley to the south. The Sacramento and San Joaquin Valleys have been filled to their present elevations with thick sequences of sediment derived from both marine and terrestrial sources.The sedimentary deposits range in thickness from relatively thin deposits along the eastern valley edge to more than 25,000 feet in the south central portion of the Great Valley (Norris and Webb, 1990).The sedimentary geologic formations of the Great Valley province vary in age from Jurassic to Quaternary, with the older deposits being primarily marine in origin.Younger sediments are continentally derived and were typically deposited in lacustrine, fluvial, and alluvial environments with their primary source being the Sierra Nevada Range. Phase I Environmental Site Assessment Page 93100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 The Sierra Nevada geomorphic province is a 40-to 50-mile wide dipping fault block consisting of a series of uplifted Mesozoic granitic batholiths overlain by metamorphic and volcanic units that is 450 miles long. Elevations in the range extend from 400 feet in the western foothills up to 14,000 feet on its eastern edge where extensional block faulting of the basin and range province has produced high peaks and dramatic relief. Steep, rocky faces and glacier carved valleys feed high-energy streams descending to rolling foothills, where plutonic and metamorphosed rock abut flat-lying alluvial sediments of the province’s western boundary with the Great Valley.(Norris and Webb, 1990).The Sierran block extends west beneath the Cenozoic alluvium of the Great Valley to presumably contact the Eastern Franciscan Formation of the Coast Ranges. The complex structure of the Sierra Nevada is reflective of its equally complex geologic history. Faulting in the western Sierra Nevada mountains trends North-northwest. The 1992 USGS Geologic Map of the Chico Quadrangle, California, shows the Site to be underlain by the Tuscan Formation.The Tuscan Formation consists of a series of layers deposited by streams and mudflows between two and four million years ago. The mudflows spread out over the area, burying older rock, filling low areas, and gradually building a flat subdued landscape. The Tuscan Formation is characterized by near horizontal layers within the formation and four-million-year-old volcanic ash horizon at the bottom of the formation. The Tuscan Formation is of Pliocene age and comprises volcanic mudflows, tuff, breccia, sandstone, and ash deposits. 4.1.2 Soil Survey The United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS) has created a web-based service for accessing soil information. According to the NRCS Web Soil Survey (WSS) the majority of the near-surface soils on the Site consist of Doemill-Jokerst , 3 to 8 percent slopes;Doemill-Jokerst-Ultic Haploxeralfs, thermic complex, 3 to 8 percent slopes; and,Jokerst-Doemill-Typic Haploxeralfs , 8 to 15 percent slopes (USDA, 2019). A copy of the soil report is included on the attached CD. 4.1.3 Regional and Local Groundwater The Site is located to the east of the California Department of Water Resources (DWR) defined Sacramento Valley Groundwater Basin of the Sacramento River Hydrologic Region. WKA searched data on the DWR website and found no DWR monitored groundwater wells within one-half mile of the Site (DWR,2019). Phase I Environmental Site Assessment Page 103100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 WKA also searched the State Water Resources Control Board’s (SWRCB) GeoTracker website for quarterly groundwater monitoring reports completed for facilities in the immediate vicinity of the Site. No facilities are located within one-half mile of the Site (SWRCB,2019). 4.2 Historical Use Information WKA reviewed historical information to develop a history of the previous uses of the Site and surrounding area, in order to evaluate the Site and adjoining properties for evidence of RECs. Standard historical sources reviewed during the preparation of this report included the following, as available: Sanborn®Maps; Topographic Maps; Oil and Gas Well Maps; Aerial Photographs; Ownership Records; Building Department Records; Local Street Directories; Zoning and Land Use Records; Other Historical Sources; and, Prior Assessments. Discussion of these historical sources is provided in the following sections. 4.2.1 Sanborn® Maps Sanborn®Maps with coverage of the Site were obtained through Environmental Data Resources, Inc. (EDR®). EDR®is a national commercial provider of environmental database information. Sanborn®Maps are detailed drawings of site development, and were typically used by fire insurance companies to determine site fire insurability. According to EDR®, Sanborn® Map coverage of the Site is not available (EDR®,2019a). 4.2.2 Topographic Maps Historical USGS topographic maps with coverage of the Site and outlying land areas were reviewed. Topographic maps with coverage of the Site dated 1891, 1893,1895,1912, 1942, 1944, 1951, 1969, and 2012 were available for review (EDR®,2019b).Copies of the topographic maps compiled by EDR®with coverage of the Site are included on the CD attached to the back cover of this report.

The Tuscan Ridge Golf Club, 3100 Skyway, was located at the Site. The Tuscan Ridge Golf Club is listed on the Department of Toxic Substances Control (DTSC) Haznet, the California Air Resources Board’s Emission Inventory Data, the Certified Unified Program Agency (CUPA), the California Environmental Reporting System, the National Pollution Discharge Elimination System, the California Integrated Water Quality System, and the Facility Index System. The DTSC Haznet database is a list of all facilities that have submitted manifests for the disposal of hazardous waste at a landfill. A listing on either database is not considered to be indicative of a release of a hazardous material or petroleum product at a property. According to the EDR Radius Report, a manifest was submitted to DTSC for the disposal of unspecified organic liquid mixture in 2006. The remaining databases do not indicate that a release of hazardous materials or petroleum products have occurred at the Site. Based on the information reviewed, this facility has not impacted the Site. Phase I Environmental Site Assessment Page 163100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 4.3.2 Preliminary Screen for Vapor Encroachment Conditions WKA conducted a preliminary screening for VEC beneath the Site using the Tier 1 vapor encroachment screening evaluation1. The Tier I screening included performing a Search Distance Test to identify if there are any known or suspect contaminated properties surrounding or upgradient of the Site within specific search radii, and a Chemicals of Concern (COC) Test (for those known or suspect contaminated properties identified within the Search Distance Test) to evaluate whether or not COC are likely to be present. The Vapor Encroachment Screening Matrix is included in Appendix D. Based on the completion of the VEC-screening matrix, a VEC can be ruled out because a VEC does not or is not likely to exist. 4.3.3 Environmental Lien Search Tuscan Ridge Associates, LLC did not authorize WKA to conduct a search for environmental liens and AULs. 1 The Preliminary Screen for Vapor Encroachment Conditions was based on the guidelines presented in the ASTM E 2600-15 Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions. Phase I Environmental Site Assessment Page 173100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 5.0 CONCLUSIONS AND RECOMMENDATIONS 5.1 Data Gaps The time intervals between the Standard Historical Sources (i.e., topographic maps, aerial photographs, other historical sources) exceeded the ASTM minimum five-year period. However, the use of the Site appears unchanged within the time gaps, and therefore, research of the Site use during the time gaps is not required by the ASTM Standard (Refer to Section 8.3.2.1 –Intervals of the ASTM E 1527-13 standard). It is the opinion of WKA that no significant data gaps were identified during the preparation of this report that affects the ability of the Environmental Professional to identify RECs on the Site. 5.2 Conclusions The historical land use research dating back to the late 1800s revealed that the Site was vacant land from at least 1891 to at least 1998.Railroad tracks were present on the southern portion of the Site by 1941. The Site was developed with a golf course, with three structures on the southeastern portion, by 2006. In December 2018, the Site was graded and aggregate base was spread across the majority for the development of an emergency basecamp for Pacific Gas & Electric (PG&E)and other contractors responding to areas impacted by the Camp Fire. During a visit to the property on January 2, 2019, WKA observed a mobile fueling area on the central portion of the Site. WKA observed stained soils in the vicinity of mobile fuel trucks.Subsequent site inspections were conducted on February 15, 2019, and April 9, 2020. Site inspection reports for the subsequent visits describe that the mobile fuel area was re-graded by February 15, 2019, and that PG&E had reportedly excavated diesel impacted soil to bedrock and disposed of it off-site. During a visit to the property on January 18, 2019, WKA observed two aboveground storage tanks (ASTs) on the southeastern portion of the Site. WKA was not provided additional information regarding the ASTs. During a visit to the property on April 9, 2020, WKA observed that the Site was no longer being used as a basecamp. The two ASTs observed in January 2019 remained on the property. WKA observed that the majority of the Site’s surface had been graded with gravel. WKA observed two lined ponds on the southern portion of the Site. WKA also observed a series of green, PVC pipes protruding vertically from the ground on the southwest portion of the Site. The pipes are associated with a new septic system that has been installed at the Site. Phase I Environmental Site Assessment Page 183100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 Given the age of development on the Site, it is unlikely that asbestos containing building materials and lead-based paints were used in the construction and/or maintenance of the Site buildings. Given the documentation reviewed concerning the agency listings for neighboring facilities, none of the facilities reviewed is likely to have a negative impact on the Site. Based on the completion of the vapor encroachment condition (VEC) screening matrix, WKA concludes a VEC can be ruled out because a VEC does not or is not likely to exist. WKA has performed this ESA in conformance with the scope and limitations of ASTM Standard Practice E 1527-13 for the Tuscan Ridge Property. We have performed a Phase I ESA in conformance with the scope and limitations of ASTM Practice E 1527-13 for the Tuscan Ridge Property. Any exceptions to, or deletions from, this practice are described in Section 5.4 of this report. This assessment has revealed no evidence of RECs in connection with the Site except the following: On-site concerns were noted from the presence of railroad tracks along the southern property boundary by at least 1941. On-site concerns were noted from the two ASTs located on the southeastern portion of the Site. A full copy of this ESA report, in a .pdf format, is included on the attached CD. 5.3 Recommendations Based on the conclusions presented and the documentation contained herein, WKA makes the following recommendations: WKA recommends collection of shallow soil samples along the former rail alignment for analysis of CAM 17 metals,Organochlorine pesticides, total petroleum hydrocarbons, PAH’s WKA recommends collection of two shallow soil samples in the area of the above ground fuel storage tanks to assess the effectiveness of the secondary containment. These samples should be analyzed for Total Petroleum Hydrocarbons, BTEX, and Fuel oxygenates. WKA was notified PG&E verbally during the Site walk about the stained soil in the vicinity of the mobile fueling area. In a subsequent visit to the Site on February 15, 2019, WKA noted that PG&E had withdrawn from the Site and had reportedly excavated the area where the mobile fueling operation had been and disposed of any impacted soil Phase I Environmental Site Assessment Page 193100 SKYWAY PROPERTY April 21, 2020 WKA No.12206.04 off site. WKA recommends contacting PG&E environmental services to request documentation of stained soil removal activities. 5.4 Exceptions and/or Deletions No exceptions or deletions from the ASTM E 1527-13 standard were made during the performance of this ESA. 5.5 Additional Services Non-scope considerations, such as assessment for naturally occurring asbestos (NOA), wetlands evaluation, indoor air quality, laboratory testing of the soils and groundwater beneath the Site for environmental contaminants (such as agricultural-related pesticides, termiticides, polychlorinated biphenyls [PCBs], or arsenic and lead), and assessments for asbestos containing materials and lead-based paint were not included or requested as part of this ESA.Additionally, this ESA included conducting a Tier 1 vapor encroachment screening in accordance with the ASTM E 2600-15 Vapor Encroachment Screening on Property Involved in Real Estate Transactions.

If Yes, then: Yes No If No, then screening for a VEC is complete and no VEC currently exists, go to #4. If Yes, then: If Yes, check all COC that apply on attached Table B. (3a) Is information related to the contaminated(s) plume available (i.e. isoconcentration maps, site drawings, etc.)? Yes No (3b) If No , then screening for a VEC is complete and no VEC currently exists, go to #4. If Yes , then: (3c) Is the site less than 100 feet to the nearest edge of a contaminated [non-petroleum hydrocarbon] plume(s)? Yes No (3d) Is the site less than 30 feet to the nearest edge of a dissolved petroleum hydrocarbon plume(s)? Yes No (4) Is it likely that a VEC currently exists beneath the site? Yes No If Yes, then recommend performing a full scope VEC assessment according to ASTM E 2600-15. [1] Based on guidance presented in the ASTM E 2600-15 Standard. [2] Chemical(s) of concern (COC): See attached table for typical chemicals of concern (as presented in Appendix X6.1 of the ASTM E 2600-15 Standard). If the distance from the nearest edge of a contaminated plume to the nearest existing or planned structure on the site is less than 100 feet for non-petroleum hydrocarbon COC, or less than 30 feet for dissolved petroleum hydrocarbons, then it is presumed that a VEC currently exists beneath the site. If the distance from the nearest edge of the contaminated plume is greater than or equal to 100 feet for non-petroleum hydrocarbons, or 30 feet for dissolved petroleum hydrocarbon chemicals of concern, then it is presumed unlikely that a VEC currently exists beneath the site. (1) Search Radius Test: Are there any known or suspect contaminated sites in the primary area of concern within the corresponding search radii? (if yes, see attached Table A). (2) Chemicals of Concern[2] Test: Are COC likely to be present within the area of concern for those known or suspect contaminated sites identified based on the Search Distance Test? (3) Critical Distance Test: A plume test to determine whether or not COC in the contaminated plume(s) may be within the critical distance. Phase I ESA Screen for Vapor Encroachment Conditions (VEC) matrix includes a (1) Search Radius Test, (2) Chemicals of Concern Test (COC), and (3) a Critical Distance Test[1].

Roseville Parkway Suite 140, Box 247 Roseville, California 95661 Site Inspection Report II (April 9, 2020) 3100 SKYWAY PROPERTY Paradise, California WKA Project Number 12206.04 Dear Mr.Bates: At your request, Wallace-Kuhl & Associates conducted an April 9, 2020 site visit of your 175- acre Tuscan Ridge property located at 3100 Skyway between Paradise and Chico, California (Figure 1).The property had been leased by ECC Constructors, LLC,for base camp operations related cleanup of the Camp Fire in Butte County.Since the summer of 2018, the Site has been the focus of much activity. This activity includes: PG&E Vegetation Management Camp, Summer 2018 to November 2018 PG&E Emergency Response Operations, November 7, 2018 to February 15,2019 Base Camp Utility Installations, February 2019 to April 2019 Camp Fire Debris Removal Base Camp April 2019 to March 2020 WKA conducted an initial site inspection related to a Phase I Environmental Site Assessment on January 2, 2019.During this initial site inspection, the property was crowded with PG&E and subcontractor equipment including sleeping trailers, dinning and recreation tents and hundreds of vehicles. WKA was told that the property had previously contained a golf course and noted a golf-related maintenance area with older mowing and grounds keeping equipment, a club house, storage building and golf cart charging station. Beyond the golf-related equipment, WKA noted the following features or activities apparently linked to PG&E or subcontractors: : Secondary containment for incidental fuel spills under mobile equipment. Stained soils in the vicinity of the mobile fueling operation located on the eastern 1/3 of the property. PG&E personnel were verbally notified of the stained soil and petroleum Site Inspection Report II (April 9, 2020)Page 2 3100 SKYWAY PROPERTYWKAProject No 12206.04 April 15, 2020 odors in soil,during inspection.The location of the fueling area was delineated by WKA personnel using a high precision GPS. Evidence of stormwater-related erosion at the western or lower end of the property Covered and uncovered soil stockpiles of unknown origin Large quantities of imported aggregate base rock On February 15, 2019, WKA completed a second site inspection at the request of Scott Bates. Mr. Bates indicated that PG&E had vacated the site and he wished to confirm the condition of the property. During this second inspection, WKA noted that the site was nearly vacant of PG&E equipment and personnel,but large quantities of aggregate base rock remained on the property.The only significant activity at the time of the inspection were several pieces of heavy equipment working on the southern portion of the property moving piles of wood mulch. Details of WKA observations during the February 15, 2019 Site Inspection can be found in the February 26, 2019 WKA Site Inspection Report but included observations of Site activities and descriptions of significant soil/gravel erosion and failure of the storm water best management practices (BMPs). Follow the February departure of PG&E, planning and excavation activities were conducted to construct two waste water detention ponds and a large septic and specialized leach field system in preparation for the debris removal base camp related to the Camp Fire. Base camp construction began on April 14, 2019.Base camp operations consisted of equipment storage, housing, dining and recreational activities as well as cleanup logistics. By late March of 2020, the base camp operations ceased on the property. On April 9, 2020, WKA conducted a post-base camp Site inspection. On the day of our inspection, the Site was covered with significant amounts of imported crushed rock and aggregate base material that had been used to construct pads for various roads, parking areas and temporary structures (Figure 2a). A permanent Quonset hut-type structure was noted on a concrete pad on the eastern 1/3 of the property. The structure appeared new but was empty. Other structures on the property included the former golf club house, maintenance building and former golf cart storage canopy. Site Inspection Report II (April 9, 2020)Page 3 3100 SKYWAY PROPERTYWKAProject No 12206.04 April 15, 2020 The two waste water ponds were noted near the southern property line and appeared to be approximately 4.5 acres.The ponds were lined and surrounded by chain-link fence.WKA also noted a line of green vent pipes located west of the former golf club house (Figure 2b). These vent pipes are apparently part of the leach field bioactive system installed for base camp operations. Other notable observations included the presence of two large trenching machines and a small maintenance area (Figures 2a and 2b). The maintenance area contained two empty 55-gallon drums labeled hydraulic fluid and one poly-cube approximately four-feet on each side and encased in a steel cage for transport. The cube was approximately 1/3 full of dark fluid but did not appear to be leaking. Other items in the maintenance area included welding tables, rock bits and other replacement parts for the trenching machines. Several square concrete pads, approximately five feet on a site were noted in the central portion of the property (Figure 2b). The pads each had numerous conduits (presumably electrical) protruding from them. Each of the conduits was capped with a plastic plug. WKA did not observe areas of stained soil, distressed vegetation or other indications of contamination and did not observe the mulch piles that were previously documented on the site. If you have questions or comments on the above site inspection report, please do not hesitate to contact me. Wallace-Kuhl & Associates Kurt Balasek, P.G., C.HG.
