Picture taken on June 7, 2023 CORCO - Peuelas, PR Photo Documentation Picture 1 View of a gasoline pump station located under a roof. Picture 2 View of the diesel pump station located under a roof. Fuel stains were observed at the floor. Picture 3 View of the back side of the diesel pump station. Fuel was observed over the floor and absorbing material was placed at the pipe that feeds the pump. Page 1 of 11 Picture taken on June 7, 2023 CORCO - Peuelas, PR Photo Documentation Picture 4 View of the abandoned plant besides the fuel pump stations in Pictures 1 and 2. The structures were corroded and deteriorated. Picture 5 The red arrow depicts the water coming from the secondary containment of Tank 1014. The yellow arrow shows a groundwater discharge coming from underneath Tank 1021. A stain was observed in the concrete wall where the discharge occurs, and the ground was green like slime. Both discharges reach the stormwater concrete channel at the north side of the Facility and eventually discharge through Outfall 003. Picture 6 View of tank 1014. The secondary containment had standing water and it was being discharged into the stormwater concrete channel at the north side of the Facility during the Inspection. Page 2 of 11 Picture taken on June 7, 2023 CORCO - Peuelas, PR Photo Documentation Picture 7 View of the water accumulated at the secondary containment of tank 1014. Brown sediments were observed at the bottom of the secondary containment, the water was clear, and no oil sheen was observed. Picture 8 View of the Facility from the north side. Corroded tanks were observed. The arrow depicts the discharge coming from the secondary containment of tank 1014. Picture 9 View of the abandoned plant at the north side of the Facility. The structures were corroded and deteriorated. Page 3 of 11 Picture taken on June 7, 2023 CORCO - Peuelas, PR Photo Documentation Picture 10 View of motors and mechanical equipment placed over the concrete floor exposed to stormwater. Equipment was corroded and deteriorated. Picture 11 View of a concrete stormwater channel that conveys stormwater from the north side of the Facility into Outfall 003. This concrete stormwater channel is commonly referred to as "Tren Urbano". The water was turbid, had sediment and a brown/green color. Picture 12 Another view of a stormwater conveyance concrete channel shown in the previous picture. Sediments were observed at the bottom of the channel and the water had a brown/green color.

Picture 14 View of Oil Trap Box #1 located between tanks 903 and 950. Sediment was observed accumulated at the bottom of the tank and waste was observed floating at the water surface including plastic bottles, foam cups, and leaves. Picture 15 View of Oil Trap Box #2 near tank 902. Fuel residues, oil sheens and waste (like foam cups and water bottles) were observed floating at the water surface. Fuel odors were perceived.

Sediment was observed accumulated at the bottom of the tank reaching above the water surface. Picture 17 View of the Oil Trap Box #3 located besides the WWTP. Picture 18 View of Oil Trap Box #3. Oil sheens and waste (like water bottles, foam cups and plates) were observed floating at the water surface. The water had a dark green color.

The flow meter is located after the red box. Picture 21 The yellow arrow depicts the location where the flow meter is located, which is after the sampling point. Page 7 of 11 Picture taken on June 7, 2023 CORCO - Peuelas, PR Photo Documentation Picture 22 Depicts a view of the shed where the automatic sampler and the flowmeter for Outfall 003 are located. Also, a sign was place in front of the shed that reads "Punto de Muestreo Descarga 003". Picture 23 View of the flowmeter located in the shed. The reading shows a value of 2353.49 gpm. Mr. Seda explained that the negative reading is because the direction of flow in the channel is towards the Facility, rather than into the water body. It shows a sticker with the calibration and the next schedule calibration is in July 2023. Picture 24 View of the sampling location for Outfall 003 at the Effluent Channel. The red arrow indicates the direction of the flow in the Effluent Channel. The yellow arrow depicts the location of the automatic sampler inlet tube and where the water sample for monitoring is taken. Outfall 003 was accessible and free of vegetation, debris, and trash.

Absorbent booms were installed. Picture 26 View of Outfall 001 located after Outfall 003 at the Effluent Channel. A label was observed and reads "Punto de Muestreo Descarga 001". Outfall 001 is accessible and free of vegetation, debris, and trash. Picture 27 View of the guillotine valves prior discharge into the effluent channel. During the Inspection, storm water was not being discharged through the guillotine valves. Page 9 of 11 Picture taken on June 7, 2023 CORCO - Peuelas, PR Photo Documentation Picture 28 View of the stormwater concrete channel that flows to Outfall 003, before the guillotine valves. Sediments were observed, and the concrete walls were deteriorated. Picture 29 View of Oil Trap Box #4 located in the North Side of the Facility. Picture 30 View of the water in the Oil Trap Box #4, the water was turbid and had a dark green color and sediments were observed. Page 10 of 11 Picture taken on June 7, 2023 CORCO - Peuelas, PR Photo Documentation Picture 31 View of the channel that conveys stormwater from the Oil Trap Box #1 into the concrete stormwater channel at the north side of the Facility. The channel was filled with sediments, the concrete walls were deteriorated, the water in the channel was green, an oil sheen was observed, and fuel odors were perceived. Picture 32 View of the same channel shown in the previous picture. The concrete headwall structure was broken and deteriorated, the channel was filled with sediments, and oil booms were installed at the entrance of each pipe. Page 11 of 11
