HTRW Phase I Environmental Site Assessment

Southwest Coastal Louisiana Non-Structural Program (LA-0020)

Tetra Tech Project Number: 100-SMX-T36978.12 October 22, 2019

EXECUTIVE SUMMARY

The Louisiana Coastal Protection and Restoration Authority (CPRA) engaged Tetra Tech, Inc. (Tetra Tech) to perform this Hazardous, Toxic, and Radioactive Waste (HTRW) Phase I Environmental Site Assessment

(ESA) in accordance with the Standard Practice for Environmental Site Assessments: Phase I

Environmental Site Assessment Process, ASTM International (ASTM): E 1527-13 for properties participating in the Southwest Coastal Louisiana Hurricane and Storm Damage Risk Reduction and

Ecosystem Restoration Project.

SITE DESCRIPTION AND PHYSICAL SETTING

The project area located at 6907 Bois Du Lac, Gueydan, Louisiana 70542 is situated in Vermilion Parish

(subject property). At the time of Tetra Tech’s site reconnaissance, the subject property consisted of a one-story brick slab-on-grade residential structure, attached carport, and two storage/work sheds.

RECORDS REVIEW

Regulatory Agency Database

There were no Envirosite Corporation listed facilities identified within the ASTM-specified search distances from the subject property.

Aerial Photography

Tetra Tech’s review of the historical aerial photographs (1952, 1970, 1972, 1974, 1978, 1981, 1985, 1990, 1994, 1998, 2004, 2005, 2007, 2009, 2010, 2013, 2015, and 2017; Appendix D) revealed that the subject property’s project area appears to have been developed into prior to 1972. The surrounding areas along the lake appear to have been partially developed into residential areas between 1981 and 1985. In the remaining aerial photographs, no significant changes occur to the subject property or the surrounding area.

Tetra Tech did not identify a previous use of the subject property or any of the surrounding properties that would represent a REC to the subject property.

Historical Topographic Map Review

Tetra Tech’s review of historical U.S. Geological Survey (USGS) Topographic Quadrangles (1946, 1954, 1955, 1984, 1994, 2012, 2015 and 2018) revealed that the subject property and the surrounding areas appear to consist of primarily of undeveloped lands and low-density residential areas. The project site is located south of Lake Arthur and north of primarily pasture land. No significant changes occur to the subject property or surrounding area in the 1954-2018 topographic maps other than changes to roadway and canal labels.

No previous use of the subject area was identified that would represent an on-site REC.

SITE AND VICINITY RECONNAISSANCE

At the time of the site reconnaissance, the subject property consisted of a one-story brick slab-on-grade residential structure, attached carport, and two storage/work sheds.

No previous use of the subject area was observed that would represent an on-site REC. (See Appendix A, Figure 3: Site Map).

INTERVIEWS

Tetra Tech conducted interviews with , the representative for the property owner, in order to obtain further information regarding environmental conditions at the subject property. was unaware of environmental liens filed or recorded against the property, activity use limitations, chemical use, chemical spills, environmental contamination, or cleanups that may have occurred on the subject property.

USER PROVIDED INFORMATION

CPRA provided no title records information for review as part of this HTRW Phase I ESA. Tetra Tech did not conduct a 50-year chain of title search for the subject property. CPRA is not aware of any environmental liens or use limitations associated with the subject property. Tetra Tech was not provided any evidence that the subject property is currently involved in any litigation regarding environmental matters. CPRA was not aware of any valuation reduction for environmental issues at the subject property.

FINDINGS AND CONCLUSIONS

Tetra Tech performed this assessment in general conformance with the scope and limitations of the ASTM

Standard E 1527-13 for the above-referenced subject property to identify RECs, historical RECs (HRECs), controlled RECs (CRECs), business risks, or de minimis conditions in connection with the subject property, including the presence, or likely presence, of hazardous substances or petroleum products in, on or at the property, due to any release to the environment, under conditions indicative of a release to the environment, or under conditions that pose a material threat of future release to the environment. This assessment included an evaluation to the extent practicable of the past and present land uses at the subject property and on adjacent properties.

The results of this assessment have identified no evidence of RECs for the subject property; however, the following on-site de minimis, housekeeping and developmental conditions and their associated recommendations were identified:

• According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map

Community Panel Number 22113C0100F with an effective date of January 19, 2011, the subject property’s project area is located within shaded Zone AE (EL 7). Shaded Zone AE represents special flood hazard areas subject to inundation by the 1.0 percent annual chance (100-year) flood event generally determined using approximate methodologies; detailed hydraulic analyses determined Base Flood Elevations (BFEs) to be 7 feet.

No further assessment of the subject property is recommended at this time.

This executive summary is presented for convenience only. While the executive summary is an integral part of the report, it should not be used in lieu of reading the entire report, including the appendices.

SECTION 1: INTRODUCTION

The Louisiana Coastal Protection and Restoration Authority (CPRA) engaged Tetra Tech, Inc. (Tetra Tech) to perform this Hazardous, Toxic, and Radioactive Waste (HTRW) Phase I Environmental Site Assessment

(ESA) in accordance with the Standard Practice for Environmental Site Assessments: Phase I

Environmental Site Assessment Process, ASTM International (ASTM): E 1527-13 for properties participating in the Southwest Coastal Louisiana Hurricane and Storm Damage Risk Reduction and

Ecosystem Restoration Project. The project area located at 6907 Bois Du Lac, Gueydan, Louisiana 70542 is situated in Vermilion Parish (subject property) (see Figure 1 – Topographic Map, Figure 2 – Vicinity

Map, and Figure 3 – Site Map in Appendix A).

This evaluation was conducted in accordance with Tetra Tech’s proposal dated August 23, 2019, and the protocols included in the ASTM International (ASTM) Standard Practice for Environmental Site

Assessments: Phase I Environmental Site Assessment Process, ASTM Designation: E 1527-13.

1.1 PURPOSE

The goal of this HTRW Phase I ESA is to identify whether recognized environmental conditions (RECs), historical RECs (HRECs), controlled RECs (CRECs), business risks, or de minimis conditions are present on the subject property. RECs are the presence or likely presence of hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of release of hazardous substances or petroleum products on the property or into the ground, groundwater or surface water of the property. The term includes hazardous substances or petroleum products, even under conditions in compliance with laws. The term is not intended to include de minimis conditions that generally do not present a material risk of harm to public health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies

(Section 1.1.1 E 1527-13, ASTM 2013). HRECs are environmental conditions that in the past would have been considered a REC, but that may or may not be considered a REC currently (Section 3.2.39 E 1527-

13, ASTM 2013). CRECS are RECs resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority, with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (Section 3.2.18 E 1527-13, ASTM 2013).

This HTRW Phase I ESA is intended to satisfy one of the requirements for the innocent landowner defense to Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) liability; that is, the practices that constitute “all appropriate inquiry into the previous ownership and uses of the property consistent with good customary practice,” as defined in 42 U.S. Code Section 9601 (35)(B).

1.2 SCOPE OF WORK

The scope of work (SOW) based on the ASTM 1527-13 Environmental Site Assessments: Phase I ESA process is to identify whether RECs are present on the subject property. Phase I ESAs typically are conducted in a four-phase process, including: records review; site reconnaissance; interviews with current owners, occupants of the subject property, and local government agencies; and preparation of a report. As part of the preparation of this HTRW Phase I ESA, Tetra Tech conducted the four-phase process detailed above in order to determine the presence of hazardous substances or petroleum products on or adjacent to the subject property and the likelihood of off-site substances migrating onto the subject property.

Any items listed in the ASTM method that are not specifically identified as being present in the report can be assumed absent from the subject property or at sufficient distance to be dismissed from potential concern.

RECs are clearly identified; any other items mentioned, but not identified as RECs are referenced for information purposes only.

Deviations from ASTM 1527-13 are described in Section 9. Report limitations are provided in Section 10.

The resumes of the environmental assessors conducting the site visit and preparing the report are provided in Appendix B.

In addition to the subject property visit, Tetra Tech reviewed readily available resources including aerial photographs, property maps, regulatory records, soil surveys, and U.S. Geological Survey (USGS) topographic maps, and regulatory records. Section 12 provides a list of referenced documents used during this investigation.

The sampling and analysis of asbestos, mold, radon, vapor intrusion, lead paint, lead in water, soil and/or groundwater samples, and the evaluation of wetlands, indoor and outdoor air quality, regulatory compliance, naturally occurring radioactive material (NORM), industrial hygiene, or noise impacts were beyond the scope of this evaluation. Similarly, the identification of endangered or protected plant and animal species or historical and archaeological sites was beyond the scope of this assessment, as were the identification and evaluation of geological or geotechnical hazards.

1.3 INVOLVED PARTIES

Tetra Tech conducted the HTRW Phase I ESA on behalf of CPRA. Additionally, , the landowners for the subject property, provided Tetra Tech with information regarding their knowledge of the subject property.

SECTION 2: SITE DESCRIPTION AND PHYSICAL SETTING

This section provides a brief description of the subject property and the physical setting based on information obtained from the site visit and a records review prior to the site visit. Observations regarding the current land use of the subject property and adjoining facilities made during the site reconnaissance are described in Section 4, Site and Vicinity Reconnaissance.

2.1 SITE DESCRIPTION

The subject property is located at 6907 Bois Du Lac, Gueydan, Louisiana 70542 is situated in Vermilion

Parish. At the time of Tetra Tech’s site reconnaissance, the subject property consisted of a one-story brick slab-on-grade residential structure, attached carport, and two storage/work sheds.

2.2 VICINITY DESCRIPTION

The subject property is located in a low-density residential area south of Lake Arthur in Vermilion Parish, Louisiana. See Appendix A: Figure 2 Vicinity Map.

2.3 PHYSICAL SETTING

This section discusses the physical settings of the subject property and details the topography, hydrology and geological information.

2.3.1 Topography

According to the USGS 7.5-minute series Lake Arthur, Louisiana Topographic Map (dated 2018), the subject property is approximately 5.574 feet above sea level. The topographic gradient in the area of the subject property is generally to the North toward Lake Arthur.

2.3.2 Wetlands

Readily available data was reviewed to determine the subject property status with respect to wetland designation, or the potential existence of wetlands. Data sources reviewed include the Envirosite

Corporation Geological Findings Map, which illustrates subject property conditions as reported by

Envirosite, and an on-line query of the “Wetlands Interactive Mapper” made available by the U.S. Fish and

Wildlife Service (USFWS) National Wetlands Inventory (NWI) website. According to Tetra Tech’s review, no wetlands were identified on the subject property’s project area.

2.3.3 Floodplain

According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map Community

Panel Number 22113C0100F with an effective date of January 19, 2011, the subject property’s project area is located within shaded Zone AE (EL 7). Shaded Zone AE represents special flood hazard areas subject to inundation by the 1.0 percent annual chance (100-year) flood event generally determined using approximate methodologies; detailed hydraulic analyses determined Base Flood Elevations (BFEs) to be 7 feet.

2.3.4 Threatened and Endangered Species

Readily available data was reviewed to determine the listed status of the parish with respect to the presence of threatened or endangered species. Based on a list of endangered species for Vermilion Parish, Louisiana, provided by the USFWS website Information for Planning and Conservation (IPaC) tool, there is one threatened species (West Indian manatee) for the subject property in Vermilion Parish.

2.3.5 Hydrogeology and Geologic Setting

The subject property is located in Vermilion Parish, Louisiana. According to the USGS geologic information presented in the Envirosite Report, the subsurface geology at the subject property’s project area consists of Late Pleistocene-age sediments.

According to the Envirosite Corporation Report, and the U.S. Department of Agriculture (USDA) Natural

Resources Conservation Service (NRCS), the predominant soils beneath the subject property are characterized as Crowley Series. This classification indicates that the soils have a silt loam texture.

Crowley Soils are somewhat poorly drained, have a high corrosion potential for uncoated steel, and are hydric. A representative profile of Crowley Soils indicates that they are silt loam from 0 to 16 inches below ground surface with no data from 16 to 60 inches.

Based on a review of hydrologic data provided in the Envirosite Corporation Reports, there are four federal

USGS water wells, no federal public water supply systems, and no state water wells located within 1.0 mile of the subject property. The closest water well is approximately 0.128 miles northeast of the subject property. See Appendix C for complete well details.

Information regarding the regional groundwater flow was not provided by Envirosite Corporation. The shallow hydrogeologic gradient flow is assumed to mimic the local topographic gradient in the vicinity of the subject property, which is generally to the North toward Lake Arthur. It should be noted that hydraulic gradient may vary with depth, regional groundwater flow direction, and be influenced by seasonal changes, geology, or local groundwater pumping patterns. Groundwater flow direction measurements would be necessary in order to determine the actual on-site direction and gradient.

SECTION 3: RECORDS REVIEW

The purpose of the records review is to obtain and review records that will help identify RECs, HRECs, CRECs, or de minimis conditions in connection with the subject property.

3.1 REGULATORY AGENCY DATABASE REVIEW

Tetra Tech reviewed federal, state and local records to assess whether the subject property or facilities within the approximate minimum search distance have experienced significant unauthorized releases of hazardous substances or other events with potentially adverse environmental effects. Envirosite

Corporation performed a database search of the subject property’s project areas in accordance with ASTM

1527-13 standards. A copy of this report is included as Appendix C.

The databases searched have been developed and are updated by federal, state and local agencies. While these databases are reliable and comprehensive, there have been cases where the data presented are out of date and no longer reflect actual facility conditions. The Environmental Records Searched section of the

Envirosite Corporation Report in Appendix C identifies when each database was updated.

The table below summarizes the federal and state databases that Envirosite Corporation searched and the number of occurrences encountered within the applicable search radii.

3.1.1 Subject Property Regulatory Listings

The subject property was not identified on the databases searched by Envirosite Corporation.

3.1.2 Vicinity Regulatory Listings

No Envirosite Corporation-listed facilities were identified within the applicable ASTM-specified search distances from the subject property.

3.2 HISTORICAL USE INFORMATION

Tetra Tech gathered historical data regarding the subject property and surrounding area to identify past uses and evaluate visible environmental issues that may constitute RECs. The following sections describe the aerial photographs, topographic maps, and chain-of-title information available for the subject property.

3.2.1 Aerial Photographs

The objective of an aerial photography review is to identify past activity that could suggest hazardous substances use, storage or disposal at the subject property, including industrial activities, open-pit dumping, tank or drum storage and disposal, or use of industrial holding ponds or lagoons. These activities and associated objects can be identified by a combination of visual characteristics (size, shape, tone, shadow, and pattern).

Tetra Tech reviewed the historical aerial photographs (1952, 1970, 1972, 1974, 1978, 1981, 1985, 1990, 1994, 1998, 2004, 2005, 2007, 2009, 2010, 2013, 2015, and 2017; Appendix D), obtained from Envirosite

Corporation, revealed that the subject property’s project area appears to have been developed into prior to

1972. The surrounding areas along the lake appear to have been partially developed into residential areas between 1981 and 1985. In the remaining aerial photographs, no significant changes occur to the subject property or the surrounding area.

The historical use of the subject property as undeveloped agricultural and residential represents a de minimis on-site condition. No previous use of the subject property or any of the surrounding properties was identified that would represent a REC. Copies of the historical aerial photographs are included in Appendix

D.

3.2.2 Sanborn Map Report

Fire Insurance maps can provide information such as building usage, building construction materials and other information related to potential risks from fire. Therefore, these maps can provide information on fuel and other tanks present on a given site historically. No Sanborn Map coverage was available for the subject property or surrounding areas. A copy of the No Coverage Sanborn Map report is included in

Appendix C.

3.2.3 Historical Topographic Maps

Tetra Tech reviewed the historical U.S. Geological Survey (USGS) Topographic Quadrangles (1946, 1954, 1955, 1984, 1994, 2012, 2015 and 2018) revealed that the subject property and the surrounding areas appear to consist of primarily of undeveloped lands and low-density residential areas. The project site is located south of Lake Arthur and north of primarily pasture land. No significant changes occur to the subject property or surrounding area in the 1954-2018 topographic maps other than changes to roadway and canal labels.

No previous use of the subject property or the areas surrounding the subject property was identified that would represent a REC. Copies of the historical topographic maps are included in Appendix D.

3.2.4 Chain of Title

A 50-year chain of title was not obtained for the subject property.

3.2.5 Previous Environmental Reports

Tetra Tech was not provided with previous environmental reports for the subject property.

SECTION 4: SITE AND VICINITY RECONNAISSANCE

Mr. Joe Cancienne, environmental professional with Tetra Tech, conducted the site reconnaissance on

September 12, 2019. The site reconnaissance consisted of walkover survey observing the subject property, structures, improvements, and boundaries with adjoining properties for obvious environmental conditions related to operations of the subject property, adjacent and surrounding properties.

4.2.14 Utilities

Utilities currently provided to the subject property include well water and electricity. The owner also stated the house is equipped with a septic system.

4.2.15 Suspect Asbestos-Containing Materials

Typical building materials that contain asbestos are found in a variety of types and uses. Frequently-encountered types of asbestos-containing materials (ACM) used in building construction include floor tile, linoleum, mastic, ceiling tile, spray-applied acoustical or decorative ceiling materials, plaster, drywall and drywall joint compound, insulation, roofing and flashing, and many other materials in common use prior to

1978. Materials that contain over 1.0 percent asbestos fibers are considered ACM and if disturbed, must be handled according to Occupational Safety and Health Administration (OSHA) and U.S. Environmental

Protection Agency (EPA) regulations. ACM identified as “friable” (capable of being crumbled, pulverized or reduced to powder by hand pressure) have greater potential for release of fibers to the atmosphere and are therefore of greater concern than non-friable ACMs. Friable ACM that are damaged will require abatement and removal prior to renovation and demolition of the structure.

Tetra Tech did not observe any evidence of ACM on the subject property during the site reconnaissance.

4.2.16 Suspect Lead-Based Paint

The use of lead-based paint (LBP) in housing was prohibited by the EPA in 1979. The Residential Lead-

Based Paint Hazard Reduction Act, commonly known as Title X, was enacted in the U.S. in 1992 and EPA regulations pertaining to Title X were implemented in September and December of 1996.

Tetra Tech did not observe any evidence of LBP on the subject property during the site reconnaissance.

4.2.17 Oil and Gas Wells, Pipelines, and Mine Shafts

As part of this assessment, a search was conducted by Envirosite Corporation to locate known oil and gas wells within an approximate 1.0-mile radius from the subject property’s project area. According to the

Envirosite Corporation Report, 13 oil/gas wells were identified within 1.0 miles of the subject property’s project area. According to the Envirosite Corporation Report and the Louisiana Department of Natural

Resources Strategic Online Natural Resources Information System, no wells are located on the subject property. A copy of the oil and gas well search is included in the Envirosite Corporation Report in Appendix

SECTION 7: FINDINGS

The results of this assessment have identified evidence of no RECs for the subject property; however, the following on-site de minimis, housekeeping, and developmental conditions were identified:

• According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map

Community Panel Number 22113C0100F with an effective date of January 19, 2011, the subject property’s project area is located within shaded Zone AE (EL 7). Shaded Zone AE represents special flood hazard areas subject to inundation by the 1.0 percent annual chance (100-year) flood event generally determined using approximate methodologies; detailed hydraulic analyses determined Base Flood Elevations (BFEs) to be 7 feet.

SECTION 8: CONCLUSIONS

Tetra Tech has performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E 1527-13 of 6907 Bois Du Lac, Gueydan, Louisiana 70542 located in

Vermilion Parish (subject property). Any exceptions to, or deviations from, this practice are described in

Section 9 of this report.

The results of this assessment have identified evidence of no RECs for the subject property; however, Tetra

Tech recommends the following for the on-site de minimis, housekeeping, and developmental conditions:

• According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map

Community Panel Number 22113C0100F with an effective date of January 19, 2011, the subject property’s project area is located within shaded Zone AE (EL 7). Shaded Zone AE represents special flood hazard areas subject to inundation by the 1.0 percent annual chance (100-year) flood event generally determined using approximate methodologies; detailed hydraulic analyses determined Base Flood Elevations (BFEs) to be 7 feet.

No further assessment of the subject property is recommended at this time.

SECTION 9: DEVIATIONS

There were no deletions or deviations from ASTM E 1527-13, with the exception of the following:

• Time gaps of more than five years were noted in available historical information; however, it is

Tetra Tech’s opinion that the subject property’s use did not change appreciably between these time gaps.

Tetra Tech does not believe that these deviations impair our ability to render an opinion regarding potential

RECs, CRECs, HRECs, or de minimis conditions for the subject property.

SECTION 10: LIMITATIONS

This report was compiled based partially on information supplied to Tetra Tech from outside sources and other information in the public domain. The conclusions and opinions herein are based on the information

Tetra Tech obtained in compiling the report. This information is on file at Tetra Tech’s office. Tetra Tech makes no warranty as to the accuracy of statements made by others that may be contained in the report, nor are any other warranties or guarantees, expressed or implied, included or intended by the report, except that it has been prepared in accordance with the current generally accepted practices and standards consistent with the level of care and skill exercised under similar circumstances by other professional consultants or firms performing the same or similar services. Because the facts forming the basis for the report are subject to professional interpretation, differing conclusions could be reached. Tetra Tech does not assume responsibility for the discovery and elimination of hazards that could possibly cause accidents, injuries or damage. Compliance with submitted recommendations or suggestions does not ensure elimination of hazards or the fulfillment of client’s obligations under local, state or federal laws or any modifications or changes to such laws. None of the work performed hereunder shall constitute or be represented as a legal opinion of any kind or nature, but shall be a representation of findings of fact from records examined.

Estimates and professional opinions of this potential are based on information derived from the site reconnaissance and from other activities described herein. CPRA is herewith advised that the conditions observed by Tetra Tech are subject to change. Indicators of the presence of hazardous substances and petroleum products that were not indicated or observable at the time of the most recent site reconnaissance may subsequently become present or observable.

Tetra Tech has used the standard of care recommended by Standard E 1527-13 developed by the ASTM

International. Because these standards of care set forth only minimums, any additional services and service enhancements that CPRA has authorized are contained in the scope of services.

CPRA and the USACE is the authorized user of this report. Reliance on this report by parties other than

CPRA may result in reliance on assumptions whose extent and nature could distort the meaning and impact of the estimates given in this report. This reliance could result in misinterpretation of these estimates and unwise actions based on those misinterpretations. As such, no party, except CPRA should rely on estimates for the potential of hazardous materials to exist at the subject property. The guidelines used to define hazardous substances and petroleum products were obtained from the ASTM Standard of Practice E 1527-

13. For the purposes of this report, the vicinity of the subject property is defined as properties located within approximately one-eighth mile radius of the subject property.

This ESA does not include a radon survey, lead paint sampling, a comprehensive asbestos survey or wetland delineation. This ESA report is based on information obtained from a variety of usually reliable sources, which are listed in the report. Tetra Tech does not guarantee the authenticity or reliability of the information it has received from outside sources.

This report is not a comprehensive site characterization and should not be construed as such. This report presents opinions that are based on the findings of visually observable on-site and off-site conditions, a review of specific regulatory records and historical sources, and comments made by interviewees. ESAs, by their very nature, are limited. Tetra Tech has endeavored to meet the applicable standard of care and in so doing, is advising CPRA of the ESA limitations. Tetra Tech believes this information is essential to help

CPRA identify and manage risks. These risks can be reduced, but cannot be completely eliminated, through additional research. Tetra Tech will, on request, advise CPRA of the additional research opportunities available, their impact on risk, and their cost.
