Sampling & Analysis Report August 6, 2014

1.0 Executive Summary

The summary of the findings is delineated below.

1.1 Compartment 4C

Activity Result XRF Survey 78% Positive Samples (78 positives of

99 samples) Corrosion Spot Inventory 30 ft2 of Corroded Metal Structure

Paint Chip Analysis 100% Positive Samples

1.2 Compartment 4S

XRF Survey 51% Positive Samples (25 positives of 49 samples)

Corrosion Spot Inventory 598 ft2 of Corroded Metal Structure Paint Chip Analysis 20% Positive Samples

1.3 Comparison of XRF Survey Results and Paint Chip Analysis Results

In comparing the XRF and laboratory results, the XRF results and the laboratory results were opposing in the case of Compartment 4S; namely that the XRF results indicate a positive lead-based paint reading and the laboratory analysis indicates levels of lead in the paint below the EPA definition of lead-based paint of 5000 mg/kg. This is largely due to the fact that the XRF machine tests the layers of paint down to the bare metal, which includes many layers of paint plus the primer on the steel structure referred to as “red paint”, the likely source of the positive lead-based paint reading. The paint chips that were sampled include those flaking pieces accessible to the samplers at the time. This top layer of paint itself is negative, as it did not include the red primer. Since removal of the red primer is one of the stated goals of the project, lead-based paint will be removed and affect the waste material and potentially disposal techniques.

1.3 Representative Water Analytical Results from Compartment 2P

1.3.1 Filtered

The filtered water is a non-hazardous material as all levels of metals tested are below designated EPA hazardous waste levels.

1.3.2 Unfiltered

The unfiltered water sample also indicated non-hazardous material. As such, the water will not have to be disposed as hazardous waste.

1.4 Representative Sediment Analytical Results

There are no waste standards for sediment; as such the sediment was compared to the Louisiana LDEQ Risk Evaluation Corrective Action Program (RECAP) Soil Screening Standards. The sediment sample had levels of Arsenic exceeding the

1.5 Paint Chip Toxic Characteristic Leachate Procedure

The results of the TCLP indicate that the levels of lead exceed the EPA Hazardous Waste standards of 5 mg/L. As a result, all paint chips collected during upcoming paint removal operations should be handled and disposed of as hazardous waste.

1.6 Estimated Volume of Waste

The estimated volume of waste is based on the Army Corps of Engineers’ Methods of Removal of Lead Paint from Steel Structures Technical Report. In Part III, bullet number 25, it is stated that a square foot of painted area produces between 3 and 10 pounds of waste material, which includes the abrasive material and leaded paint. The representative compartment 4S was estimated to be 10 feet wide, 8 feet high, and 30 feet long, making the total square footage of the compartment 1,240 ft2. Based on these field measurements of the representative compartment 4S and the information from the technical report, the lowest estimated amount of material produced is1.8 tons and the highest is 6.12 tons.

The estimated water volume from the representative compartment 2P is approximately 50 cubic feet, or 375 gallons. The estimated sediment volume from the same compartment, 2P, is approximately 6.25 cubic feet or 50 gallons.

1.7 Recommendations

Due to the extent of lead-based paint in the crane barge compartments, BCE- MMG recommends that all paint should be treated as lead-based paint and all personnel and activities which follow should adhere to the Occupational Safety and Health Administration (OSHA) guidelines for lead-based paint removal.

Personnel health and safety training as well as air monitoring should be conducted to ensure safe lead removal operation.

2.0 Introduction

2.1 Background

Under U.S. Army Corps of Engineers (USACE) New Orleans District (MVN) IQRC Contract W912P8-12-D-0005 Task Order 09, Bayou Cajun Enterprises – Materials Management Group Joint Venture, LLC (BCE-MMG) conducted a survey of lead-based paint and water and sediment sampling on the Crane Barge #796 (see Appendix A for site diagram). The barge is in need of repairs and repainting on the interior. It is known that lead-based paint was used on the crane barge at one time, which is a potential human health hazard and environmental contaminant.

2.2 Objectives

The purpose of the X-ray Fluorescence Spectrophotometer (XRF) survey is to identify the extent of lead-based paint coverage to be verified with representative paint chip sampling. An inventory of the location and area of corrosion was also completed to inform the engineers in charge of planning the repair and repainting of the crane barge. Representative paint chip sampling, including analysis of representative samples for metal characterization, was conducted to verify the XRF survey results as well as to determine the full metal content of the paint. A composite paint chip sample was collected from the compartments for Toxic Characteristic Leachate Procedure (TCLP) for proper waste disposal. An estimation of the volume of waste produced by repair and repainting activities was completed along with a determination of the bilge water and sediment waste characterization for disposal purposes.

3.0 Summary of Field Activities

The field activities completed under Task Order 09 included:

• An XRF survey of two (2) representative interior compartments 4C and 4S,

• Representative paint chip sampling to verify the XRF survey;

• Collection of one composite paint chip sample for Toxic Characteristic Leachate Procedure (TCLP),

• Taking an inventory of all corroded areas of the selected compartments, Materials Management Group, Inc. Page 4

• Collection of filtered and unfiltered bilge water as well as bottom sediment samples from compartment 2P for waste characterization for disposal purposes.

• Sending the samples for analysis for RCRA metals as well as TCLP

• Estimate the anticipated crane barge’s interior chambers repair waste amounts from corroded areas, as well as sand-blasting and repainting waste amounts.

3.1 Schedule

The field activities were conducted on August 13, 2014. All field activities were completed on this day. The laboratory samples were picked up by courier for hand delivery to the laboratory later in the afternoon. All analytical laboratory results were received by BCE-MMG staff on August 22, 2014. Please refer to Appendix B for photographs taken during the site activities.

3.2 XRF Testing

BCE-MMG utilized Mr. Jeff Camus to perform the XRF survey of the interior of the Crane Barge #796. Mr. Camus is an LDEQ Certified Lead Inspector (please refer to Appendix G for all LDEQ Lead Certifications). The lead-based paint survey was conducted with an X-ray Fluorescence Spectrophotometer (XRF) - Niton XLP-300A Spectrum Analyzer. The survey was conducted using the procedures dictated by the Louisiana Administrative Code, Title 33 (Environmental Quality), Part III (Air), Chapter 28 (Lead-Based Paint Activities), Section 2803 (Definitions), (LAC 33:III.2811B).

For the purposes of the XRF survey, “Lead-Based Paint” was identified as paint or other surface coatings that contain a lead concentration equal to or in excess of 1.0 milligram per square centimeter (mg/cm2). This definition is from LAC 33:III.2811B. The Niton XLP-300A instrument used to conduct the XRF survey measures lead content in milligrams per square centimeter (mg/cm2);

therefore, the evaluation involved comparing all XRF survey readings to the 1.0 mg/cm2 regulatory standard for the determination of lead content.

The XRF survey included sampling of two (2) of the crane barge’s interior chambers- 4C and 4S. The XRF survey in each of the compartments included sampling of all four sides of the chamber, the roof, and floor of 4S.

See Appendix C for the complete XRF survey results.

Materials Management Group, Inc. Page 5

3.3 Corrosion Spot Inventory

BCE-MMG’s staff conducted the corrosion spot inventory concurrently with the XRF survey to ensure all components and areas had been completed. The inventory was conducted on each of the compartments’ sides and appurtenances. The total corroded area of each side of the component was estimated visually.

The original field documentation for the inventory is found in Appendix D. Please refer to section 4 for results of the corrosion spot inventory by compartment.

3.4 Paint Chip Sampling

Representative paint chip sampling was conducted throughout chambers 4C and 4S. Five (5) paint chip samples were collected in 4C and four (4) paint chip samples were collected in 4S. The QA/QC duplicate was taken in chamber 4S.

An additional composite sample was also taken. This composite sample was taken from each of sampled areas for the purpose of TCLP testing. Paint chip samples exceeding 5000 mg/Kg is considered to be lead-based paint. Please refer to Appendix E for analytical results of the paint chip and TCLP testing.

3.5 Water Sampling

BCE-MMG personnel Dr. C. Paul Lo collected the water samples in chamber 2P on August 13, 2014. The chamber was opened via the manhole on the surface of the crane barge and air was blown into the chamber for approximately ten minutes. Using an LEL/O2 meter, the oxygen level was monitored to ensure conditions within the chamber were safe for human occupation throughout the sampling activities. Dr. Lo entered chamber 2P using the manhole entry and proceeded to collect water from throughout the chamber for laboratory analysis.

One 500 mL plastic bottle, and two 250 mL plastic bottles were filled with a representative sample of the water. The sample bottles were all put on ice and delivered to Accutest Laboratory in Scott, Louisiana, where one of the samples (4011ACE-01) was filtered and the other (4011ACE-02) analyzed without filtration.

Please refer to to Appendix E for the analytical results of the water testing.

3.6 Sediment Sampling

Dr. Lo entered chamber 2P using the manhole entry and proceeded to collect the sediment located at the bottom of the chamber. This was accomplished through the use of fine filter placed over a cup and the water/sediment mixture poured over the top. The sediment that remained in the filter was then placed in the 8

Materials Management Group, Inc. Page 6 ounce glass sampling jar, placed on ice, and delivered to Accutest Laboratory for analysis.

Please refer to Appendix E for the analytical results of the sediment testing.

4.5 Paint Chip Toxic Characteristic Leachate Procedure

The results of the TCLP indicate that the levels of metals exceed the EPA Hazardous Waste standards of 5 mg/L. As a result, all paint chips collected during upcoming paint removal operations should be handled and disposed of as hazardous waste.

4.6 Estimated Volume of Waste

Methods of Removal of Lead Paint from Steel Structures Technical Report. In Part III, bullet number 25, it is stated that a square foot of painted area produces between 3 and 10 pounds of waste material, which includes the abrasive material and leaded paint. The representative compartment 4S was estimated to be 10 feet wide, 8 feet high, and 30 feet long, making the total square footage of the compartment 1,240 ft2. Based on these field measurements of the representative compartment 4S and the information from the technical report, the lowest estimated amount of material produced is1.8 tons and the highest is 6.12 tons.

The estimated water volume from the representative compartment 2P is approximately 50 cubic feet, or 375 gallons. The estimated sediment volume

4.7 Data Quality

Before leaving the factory, Niton calibrated the XLP 300A. To further assure the best Quality Assurance/Quality Control, the XLP 300A performs a self-calibration every time the device is turned on. Once the device completes its self-calibration, the sampling technician conducts a calibration check using the Niton-supplied NIST Standard Reference Material (001233). This calibration step consists of a series of three checks with lead standard strips. Additional calibration checks are

A duplicate of a randomly chosen paint chip sample was taken to ascertain the accuracy of laboratory proceedings and ensure data quality of a high standard.

Overall, the data are sufficient quality to satisfy the objectives of this assessment and the recommendations provided in this report.

4.8 Comparison of XRF Survey Results and Paint Chip Sampling Results

In comparing the XRF and laboratory results, the XRF results and the laboratory results were opposing in the case of Compartment 4S; namely that the XRF results indicate a positive lead-based paint reading and the laboratory analysis indicates levels of lead in the paint below the EPA definition of lead-based paint of 5000 mg/kg. This is largely due to the fact that the XRF machine tests the layers of paint down to the bare metal, which includes many layers of paint plus the primer on the steel structure referred to as “red paint”, the likely source of the positive lead-based paint reading. The paint chips that were sampled include those flaking pieces accessible to the samplers at the time. This top layer of paint itself is negative, as it did not include the red primer. Since removal of the red primer is one of the stated goals of the project, lead-based paint will be removed and affect the waste material and potentially disposal techniques.

5.0 Conclusions

Lead-based paint was found throughout the compartments of the Crane Barge #796 using an X-Ray Fluorescence Spectrophotometer. These results were confirmed with paint chip sampling and laboratory analysis as well as visual inspection. The corrosion spot inventory revealed variable amounts of corrosion by compartment. Please see the following tables 5.1-5.6 for the complete summary of the findings.

6.0 Recommendations

Due to the extent of lead-based paint in the compartments, BCE-MMG recommends that all paint should be treated as lead-based paint and all personnel and activities which follow should adhere to the Occupational Safety and Health Administration (OSHA) guidelines for lead-based paint removal, including personal protective equipment (PPE) as well as monitoring.

BCE-MMG recommends health and safety training for all workers involved in lead-based paint removal to ensure proper dissemination of information. BCE- MMG recommends that the topics of lead/lead-based paint health effects, proper application and use of PPE, and prohibited activities on a lead-based paint job site (smoking and eating in the hot zone, etc).

Based on the water and sediment laboratory analysis, BCE-MMG recommends disposal as industrial waste. All paint chips and spent sandblast material should
