Only the northwest lots are included in this Phase II Environmental Site Assessment. URS has performed this Phase II ESA for the Subject Property in general conformance with the scope and limitations of the American Society for Testing and Materials (ASTM) Standard Practice for Environmental Site Assessments (Standard E ) 2.0 BACKGROUND 2.1 Site Description and Features The Subject Property is composed of six parcels totaling approximately 39.5 acres.the six parcels are identified as follows; Parcel 1 is approximately 18.8 acres in size and is located at the 3301 Rickenbacker Causeway (Folio #: ). Parcel 1 is developed with four enclosed structures, a three story building that houses a restaurant, offices, and a marine engine mechanics shop, a dock side guard shack and a fuel dock with two 10,000 gallon USTs. Parcel 2 is approximately 2,000 square feet (0.045 acre) that includes a single story building that houses the dock masters office, dockside restrooms, and private i

6 offices. It is located at 3605 Rickenbacker Causeway (Folio ). Parcel 3 consists of two lots, of which only the northwest lot is included in the report. The northwest lot is approximately 6.8 acres and it is located at 3501 Rickenbacker Causeway (Folio #: ). It is developed with a retail dock supply store and boat storage structures that include individual boat cradles and multilevel boat racks as well as the floating dock area of the marina. Parcels 4 and 5 ( and ) comprise the three story building that houses a restaurant, offices, and a marine engine mechanics shop, These two parcels are approximately 6,500 square feet (0.15 acre). Parcel 6 is approximately 5.2 acres and is located at 3511 Rickenbacker Causeway (Folio #: ). Parcel 6 is developed with: a single story building that houses a bar and restaurant, a two story building that houses the marina offices, a marine engine mechanics shop, and a bait and tackle shop, boat storage structures that include individual boat cradles and multilevel boat racks, a fuel dock that utilizes two 2,000 gallon unleaded gasoline ASTs and A 300 gallon AST at the forklift maintenance area. Based on the review of readily available information, interviews, a review of historical information and the site assessment, evidence of historical and current activities that would create an on-site REC at two of the six parcels composing the Subject Property was discovered during this assessment. Based on this information, it is URS Corporations opinion that one HREC and three on-site RECs were identified on two of the six parcels that compose the Subject Property. located at 3301 Rickenbacker Causeway at the Subject Property. The facility reported a discharge of an unspecified volume of unreported pollutant in October The Discharge Cleanup Status is listed as NFA-No Further Action and the Cleanup Work Status is listed as Completed as of November Based on this historical information, it is the opinion of URS that this site creates a HREC at the Subject Property. Waste oil storage shed, located at 3301 Rickenbacker Causeway at the Subject Property. During the site inspection, petroleum stains were observed in the entrance area of the waste oil storage shed. Mechanic s shop located at 3501 Rickenbacker Causeway at the Subject Property. During the site assessment at the Subject Property, heavy petroleum staining was observed in and around the flooring of the marine engine mechanics shop. Additionally, a petroleum sheen emanating from the front of the mechanics bay was observed on the shallow water puddles outside of the mechanics bay. The mechanics shop appears to have been in operation for many years. Based on these observations it is the opinion of URS that this feature creates a potential REC at the Subject Property. Forklift maintenance area located at 3501 Rickenbacker Causeway, at the northwest end of Parcel 3. Petroleum staining was observed on the ground in and around the forklift maintenance area. A used hydraulic ram was observed lying on the gravel ground in the area as well. Based on these ii

7 observations it is the opinion of URS that this feature creates a potential REC at the Subject Property. Based on the readily available information, interviews and a review of historical information, evidence of historical and current activities that would create an off-site REC for Subject Property was not identified during this assessment. Based on this information, it is URS Corporations opinion that no off-site RECs were identified for the Subject Property. 2.2 Physical Setting The subject property is located on the western end of Virginia Key in Miami-Dade County, Florida. The property is characterized by a U-shaped section of land at the western extent of Virginia Key with the opening of the U facing west. Within the U are the permanent dock structures. The Rusty Pelican restaurant is located on the northwestern end of the U, which is privately owned parcel not included in this assessment. The body of the U, forming the north, east, and south portions of the property identified in as Parcel 1, 2, 4 and 5 contain the restaurant, dockside offices, and the Fuel dock with USTs. The Rickenbacker Causeway lies adjacent to the southwest boundaries of the subject property. The marina continues to the west with a floating dock area and small mangrove island contained in Parcel 3, followed by Parcel 6, which forms the east end of the Subject Property. The Biscayne Bay shoreline borders the property on its interior, to its west and to its north sides. The subject property is bordered to the east by the Miami Marine Stadium Property. Topographic coverage of the area is provided by the United States Geological Survey (USGS) 7.5-minute quadrangle map of Miami, FL, dated According to the review of the USGS topographic map, the surface elevation of the subject property is approximately five feet or less above mean sea level (msl). Topography in the immediate vicinity of the subject property is essentially flat. Surface drainage occurs by sheet flow across the Subject Property toward Biscayne Bay and/or percolates into the unpaved gravel area at the subject property. 2.3 Site History and Land Use A review of historical aerial photographs indicates that the marina was constructed between 1978 and Prior to this period, the marina area was undeveloped. 2.4 Adjacent Property Land Use To the west and southwest, the subject property is bound by the Rickenbacker Causeway (S.R. 913), followed by Biscayne Bay. To the south is the Miami Marine Stadium property. To the southeast, east and northeast, is the powerboat racing lagoon, followed by mangroves. To the north is the Rusty Pelican restaurant followed by Biscayne Bay to the northwest. 2.5 Summary of Previous Assessments Based on the review of readily available information, interviews, a review of historical information and the site assessment, evidence of historical and current activities that would create an on-site REC at two iii

SB-1/GW-1 was located at the waste oil storage shed (3301 Rickenbacker Causeway) since petroleum stains were observed in the entrance area. SB-2/GW-2 was located in the front of the mechanics bay area (3501 Rickenbacker Causeway) since heavy petroleum staining was observed in and around the flooring of the marine engine mechanics shop and a petroleum sheen emanating from the front of the mechanics bay was observed on the shallow water puddles outside of the mechanics shop. SB-2/GW-2 was located in the former forklift maintenance area (3501 Rickenbacker Causeway) at the northwest end of the subject property since petroleum staining was observed on the ground iv

9 in and around the forklift maintenance area. Figure 3 shows the location of the soil and groundwater samples. 3.2 Exploration, Sampling and Test Screening Methods On June 12, 2015, URS collected three (3) soil samples (SB-1, SB-2 and SB-3) and three (3) groundwater samples (GW-1, GW-2 and GW-3) at the using a direct push technology (DPT) rig provided by Earth Tech Drilling (ETD), a Florida Certified Environmental Driller. Based on the findings of the Phase I ESA completed by URS for the, three (3) locations were selected for soil and groundwater sampling. 1. SB-1/GW-1 was located at the waste oil storage shed (3301 Rickenbacker Causeway) where petroleum stains were observed in the entrance area. It is located at latitude 25 44'45.89"N, longitude 80 10'25.75"W. 2. SB-2/GW-2 was located in the front of the mechanics bay area (3501 Rickenbacker Causeway) where heavy petroleum staining was observed in and around the flooring of the marine engine mechanics shop and a petroleum sheen was observed emanating from the front of the mechanics bay onto the shallow water puddles outside of the mechanics shop. It is located at latitude 25 44'37.93"N, longitude 80 10'20.93"W. 3. SB-3/GW-3 was located in the former forklift maintenance area (3501 Rickenbacker Causeway) at the northwest end of the subject property since petroleum staining was observed on the ground in and around the forklift maintenance area. It is located at longitude 25 44'38.40"N, latitude 80 10'17.11"W. Figure 3 shows the location of the soil and groundwater samples. Prior to sampling, a private utility locator was used to mark and clear the areas of buried utilities. URS collected soil samples every two foot intervals, from the surface to the water table interface. The collected samples were screened in the field with an Organic Vapor Analyzer (OVA). The soil samples with the highest OVA reading was collected for laboratory analysis in order to confirm or deny the presence of contaminants in the soil. In the absence of a specific high OVA reading, the sample just above the water table was collected for analysis. The samples were collected by URS personnel in bottleware provided by Pace Analytical Services Inc. (PACE). The samples were placed on ice and submitted under proper chain of custody procedures. Groundwater samples were collected at a discrete depth of approximately 12 ft. during drilling using a HydroPunch sampling device provided by ETD. Groundwater samples were collected from the same locations as the respective soil borings. The procedure for the collection of the discrete depth groundwater samples consisted in advancing a borehole to approximately 5 ft. using a geoprobe to collect the soil samples and then installing the sealed HydroPunch 4 ft. stainless still sampler screen (1.75 ) with the inner rod (1.5 ) to a depth of approximately 12 ft. Once at the sampling depth, ¼-inch diameter HDPE tubing was installed into the screen depth and slow purging initiated using a peristaltic pump for at least 20 minutes or until the water was v

10 clear. Once collected, the samples were placed on ice and submitted to PACE, under proper chain of custody procedures. Upon completion of the soil and groundwater sampling activities, all soil borings were grouted and properly abandoned. 3.3 Chemical Analytical Methods All soil and groundwater samples were analyzed for volatile organic compounds (VOCs), using EPA method 8260; semi-volatile organic compounds (SVOCs), using EPA method 8270; total recoverable petroleum hydrocarbons (TRPH), using the FL-PRO method and total metals (arsenic, cadmium, chromium and lead), using EPA ASTM D was used to determine the percent moisture in the soil samples. 4.0 PRESENTATION AND EVALUATION OF RESULTS 4.1 Subsurface Conditions At soil boring SB-1, located at the waste oil storage area, the 0-2 feet zone consisted of asphalt, limerock fill mixed with sand and traces of burnt wood fragments. At the 2-4 foot depth, the soil consisted of a grey limerock. The OVA readings ranged from 0 to 1 ppm. Groundwater was encountered at approximately four feet below land surface. The soil sample from the 0-2 foot interval was retained for laboratory analysis At soil boring SB-2, located at the entrance of the mechanic s workshop area, the foot zone consisted of asphalt and limerock fill mixed with sand. The foot zone consisted of limerock fill mixed with sand and clayey marl. At the 2-4 foot depth, the soil consisted of a limerock fill and clayey marl mixture. The OVA reading at the foot zone was 0.3 ppm. The OVA reading of the 2-4 foot zone was 1 ppm. Groundwater was encountered at approximately four feet below land surface. The sample from the 2-4 foot interval was retained for laboratory analyses. At soil boring SB-3, located at the forklift maintenance area, the feet zone consisted of asphalt, stained limerock fill mixed with sand. The foot zone consisted of limerock fill mixed with sand and clayey marl. At the 2-4 foot depth, the soil consisted of a limerock fill and clayey marl mixture. The OVA reading of the foot zone was 23.5 ppm. All other OVA readings were 0 ppm. Groundwater was encountered at approximately four feet below land surface. The soil sample from the 0-2 foot interval was retained for laboratory analyses. 4.2 Analytical s The summary of the soil samples analyses results is presented in Table 1. The results indicated that no VOCs or SVOCs were detected above the laboratory analytical method detection limit. TRPH was detected at concentrations of 108, 46.7 and 31.6 mg/kg in the samples from SB-1, SB-2 and SB-3, respectively. These concentrations are below the leachability based on vi

11 groundwater criteria, direct exposure residential and direct exposure commercial/industrial limits. Arsenic was detected at 2.8 mg/kg in the sample from SB-1 (waste oil storage area). This concentration exceeds the direct exposure residential limit of 2.1 mg/kg. Arsenic was detected in the samples from SB-2 and SB-3 at 1.6 mg/kg, which is below the direct exposure residential limit of 2.1 mg/kg. Figure 4 shows the location of the arsenic detected in the soil. Table 2 presents the summary of groundwater analyses results. None of the analyzed metals, TRPH, SVOCs or VOCs were detected in the GW-1 sample. Arsenic was detected at 203 mg/l in the GW-2 sample (mechanics workshop area). This concentration is above the groundwater cleanup target level (10 mg/l) and the natural attenuation default source concentration limit (100 mg/l). No TRPH, SVOCs or VOCs were detected above the groundwater cleanup target levels in the GW-2 sample. Arsenic was detected at 11 mg/l in the GW-3 sample (forklift maintenance area). This concentration is above the groundwater cleanup target level (10 mg/l). Benzene was detected at 1.7 µg/l, which exceeds the groundwater cleanup target level of 1.0 µg/l. Trichloroethene was detected at 16.3 µg/l, which exceeds the groundwater cleanup target level of 3 µg/l. No TRPH or other SVOCs or VOCs were detected in the groundwater sample from GW-3. Figure 5 shows the location of the detected parameters in the groundwater 5.0 INTERPRETATION AND CONCLUSIONS 5.1 Recognized Environmental Condition / Potential Release Areas. The analyses results from the waste oil storage area (SB-1/GW-1) have detected arsenic in the soil above the direct exposure residential cleanup target levels. There was no groundwater contamination detected. These results indicate a Recognized Environmental Condition The analyses result from the mechanic s workshop area (SB-2/GW-2) and the forklift maintenance area (SB-3/GW-3) indicate no affected soils, but groundwater quality has been affected. The analysis of the groundwater sample collected in the vicinity of the mechanic s workshop area indicated the presence of arsenic above the groundwater cleanup target levels and the natural attenuation default source concentrations. These results indicate a Recognized Environmental Condition The analysis of the groundwater sample collected from the vicinity of the forklift maintenance area indicated the presence of arsenic, benzene and trichloroethene at concentrations above the groundwater cleanup target levels. These results indicate a Recognized Environmental Condition vii

12 5.2 Conclusions / Objectives Met. The results of the laboratory analyses of soil and groundwater samples have indicated that there are areas of the City of Miami that have been affected by the activities at the marina. The horizontal and vertical extent of the detected parameters needs to be established, in order to design proper remediation actions as needed. The affected soils in the vicinity of SB-1/GW-1 should be evaluated to establish the extent of the arsenic in the soil. It is recommended that soil borings be stepped out from the area of SB-1/GW- 1. It is recommended that these borings be a minimum of ten (10) feet from SB-1/GW-1. Samples should be retained for analyses from the 0-2 foot and 2-4 foot depth intervals. A second set of samples should be collected from a distance of twenty (20) feet and analyzed as needed. The groundwater quality in the vicinity of SB-2/GW-2 and SB-3/GW-3 should be evaluated. Permanent monitoring wells for confirmation of the results presented in this report should be installed at the location of SB-2/GW-2 and SB-3/GW-3. Additional shallow monitor wells should be installed a minimum of twenty (20) feet from the locations of SB-2/GW-2 and SB- 3/GW-3, in order to establish the horizontal extent of the affected area. Depending on the results, additional shallow monitoring wells may be required. The groundwater in the area of SB-2/GW-2 would be evaluated for arsenic. The groundwater in the area of SB-3/GW-3 would be evaluated for arsenic, benzene and trichloroethene. viii
