Hazardous Test Analytical Data Summary

1.0 INTRODUCTION

Bhate/ZAPATA JV, LLC (BZJV) is pleased to submit this Draft-Final Report for the Oil Water Separator Sampling Event associated with Fence-to-Fence Environmental Services at Seymour Johnson Air Force Base (AFB), North Carolina. This report describes the approach used by BZJV in managing and performing the work conducted on 15-16 October 2018. Work was performed in accordance with the Performance Work Statement (PWS) for FY18-22, as provided with US Army Corps of Engineers (USACE) contract number W912HN-18-F-1005.

1.1 PROJECT APPROACH

Test America Laboratories of Arvada, Colorado, and Nashville, Tennessee, provided quantitative analysis of influent and effluent samples collected from thirteen (13) oil/water separators (OWSs) located at Seymour Johnson AFB. Samples were analyzed for:

• Toxicity Characteristic Leaching Procedure (TCLP) volatiles using method 1311/8260B;

• Total Petroleum Hydrocarbons (TPH as gasoline range and diesel range organics) using Method

8015;

• Polychlorinated biphenyls (PCBs) using method 8082A;

• Eight RCRA Metals using method 6010C/7470A;

• Total Organic Halides using method 9020B; and

• Flash Point using method 1010A.

OWSs requiring sampling included OWS 2115, 2115A, 2639, 3100, 3105, 3220, 3402, 4527, 10155, 10164, 10312, 10277, and 4531. We documented visual observations of separators (excessive sludge present, corrosion, no oil or fuel in effluent chambers, spillage around separators, broken hinges or lids, and any other maintenance recommendations).

It should be noted that due to an error during the completion of the Chain of Custodies the laboratory performed VOC analysis using Method 8260B versus TCLP 8260 as required in the PWS. Results were provided as totals in micrograms per liter (µg/L). Since total analysis results of the samples demonstrated that individual analytes were not present or in such low concentrations that the regulatory levels were not exceeded, the results can be used to screen for hazardous constituents.

1.2 OBSERVATIONS/CONCLUSIONS

Sampling activities for this project were performed from 15-16 October 2018. The BZJV samplers were Vincent Interrante and Louis Bechel. General and OWS specific observations and conclusions are provided below.

1.2.1 General Observations/Conclusions

In general all OWSs were in good physical condition. All were readily accessible and showed no signs of spillage. There were no signs of excessive sludge present, corrosion, oil or fuel in effluent chambers unless noted specifically in Section 1.2.2, below. The analytical results indicate that there were no hazardous constituents present above the hazardous waste regulatory limits in any influent or effluent samples.

The only TCLP VOCs detected in any of the samples were benzene, 2-Butanone and chloroform, which reported detections were well below the USEPA TCLP Screening Criteria of 0.5 milligrams per liter (mg/L), 200 mg/L and 6 mg/L, respectively. The reported results for flash point indicated that samples contained flashpoint values of greater than 200 oF, which does not meet the USEPA Screening Criteria of a

Oil Water Separators at Seymour Johnson AFB FA480921Q0071

Characteristic Hazardous Waste of less than 140 oF. Based on these results, the samples were not hazardous for flash point.

Several regulated metals were detected in the total metals analyses. The USEPA TCLP Rule of 20 was used to determine that the samples were not hazardous for metals. The Rule of 20 states that the concentration of a regulated analyte from the total analysis can be divided by 20 to determine if the waste sample is hazardous. The rule is based on the TCLP extraction procedure that involves diluting a sample portion with an extraction fluid that equals 20 times the weight of the sample. If all of a regulated constituent in a waste sample completely dissolves or leaches into the extraction liquid during the leaching procedure then the concentration of the constituent will always be 20 times less than the original concentration in the sample, meaning that the constituent was diluted to 1/20th of its original concentration. When a waste is analyzed for the regulated constituent without the TCLP extraction (total analysis) the concentration of a regulated analyte can be divided by 20 and the result compared to the regulatory limit.

For example, the regulatory limit for lead is 5 mg/L. If the lead concentration from the total lead analysis is divided by 20 and the result is < 5 mg/L, the waste is considered non-hazardous for TCLP purposes.

TPH in the DRO Range were found to be elevated in some of the samples. DRO concentrations in the samples ranged from 0.42 mg/L to 550 mg/L.

The Laboratory reported difficulty with analysis of some of the samples for PCBs. The difficulties were attributed to the matrix of some of the samples. These difficulties also led to a delay in the delivery of the lab reports. The only target PCB detected in any of the samples was Aroclor 1242 at 2.7 µg/L.

A summary of OWS Sample Laboratory results is presented in Table 1. Analytical Data Packages with associated Quality Control Data Summaries for the October 2018 sampling event were provided by TestAmerica Laboratories, and have been included in Appendix A.

1.2.2 OWS Specific Observations/Conclusions

OWS 10277 Heavy Equipment Wash Rack – Minimal water present in both the influent and effluent chambers. The water that was present was slightly oily and sludge was visible in the corners of both chambers.

OWS 10164 Hush House – Heavy fuel was observed in both the influent and the effluent chambers.

The unit was in good physical condition and was operating adequately. This OWS is a closed system and therefore does not discharge effluent. At the time of the field event, there were no visual indications that the OWS had leaked or discharged contents. The unit should be pumped and the excessive fuel should be separated and recycled.

OWS 10155 Hush House – The effluent chamber outlet plug was missing on the access pipe. Observations made during sample collection indicated that sludge may be present on the bottom of the OWS, but it could not be measured. Both the influent and effluent chambers possessed surface covers. Both chambers also contained excessive amounts of fuel. The unit was in good physical condition and was operating adequately. This OWS is a closed system and therefore does not discharge effluent. At the time of the field event, there were no visual indications that the OWS had leaked or discharged contents. The unit should be pumped and the excessive fuel should be separated and recycled.

OWS 2115 AGE Maintenance Underground – Both the influent and effluent chambers contained slimy and oily liquid. The bolts securing the inner lid of the effluent chamber were badly rusted and not functional. An outer lid covers the inner lid. This OWS is a closed system and therefore does not discharge effluent. At the time of the field event, there were no visual indications that the OWS had leaked or discharged contents. The unit should be pumped and the oily liquid should be removed and properly disposed.

OWS 2115A AGE Maintenance Above Ground –Excessive surface scum mixed with floating rust was visible in both the influent and effluent chambers of the OWS.

OWS 4531 AGE Parking – Both the influent and effluent chambers appeared much the same; oil sheen was visible on the surface of the water. The unit was in good physical condition and was operating adequately.

OWS 4527 AGE Storage Area – Both the influent and effluent chambers appeared much the same;

very little water was present and an oil sheen was visible on the surface of the water. The unit was in good physical condition and was operating adequately.

OWS 3402 Fuels Bulk Storage – The influent chamber had an excessive amount of oil on the surface of the water. No issues were observed in regards to the effluent chamber in the OWS. The unit was in good physical condition as a whole, and was operating adequately.

OWS 3220C Refueler Maintenance – The water inside both the influent and effluent chambers appeared to be clear. The inner chamber of the tank itself exhibited excessive corrosion. Many of the bolts on the lid were rusted. However, the unit seemed to be operating adequately.

OWS 2639 GOV Wash Rack – A slight oil sheen and a small amount of sludge were present inside both the influent and effluent chambers. The unit was in good condition and was operating adequately.

OWS 10312 GOV Fueling Station – The water in both chambers had a slight oil sheen visible on the surface. The unit was in good physical condition and was operating adequately.

OWS 3100 Vehicle Maintenance – Corrosion was visible on the influent chamber walls and drainage pipe. The tank contained a slime/scum on the surface of the water. The effluent chamber was in similar shape as the influent. The unit appeared to be corroding extensively. It is recommended that the unit be repaired or replaced.
