1.0 INTRODUCTION

In accordance with our proposal dated July 2, 2020, Tetra Tech performed a Phase I Environmental Site Assessment of the property located at Northern Oilfield Services property located at 4943 Highway 16 South, Antelope, Sheridan County, Montana (Figure 1, Appendix A; hereinafter, the “Property”) in general accordance with ASTM Standard E 1527-13. Northern Oilfield Services and their parent company H H Land & Livestock LLC (H H) are the Users of this Phase I ESA.

1.1 PURPOSE The purpose of this Phase I ESA is to assist the User in developing information to identify current and historical recognized environmental conditions (RECs) in connection with the Property as reflected by the scope of this report. ASTM Standard E1527-13 states that:

“This practice is intended for use on a voluntary basis by parties who wish to assess the environmental condition of commercial real estate taking into account commonly known and reasonably ascertainable information. While use of this practice is intended to constitute all appropriate inquiry for the purposes of LLP [landowner liability protection], it is not intended that its use be limited to that purpose. This practice is intended primarily as an approach to conducting an inquiry designed to identify recognized environmental conditions in connection with a property.”

RECs are defined by ASTM Standard E1527-13 as:

"The presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.”

The term is not intended to include de minimis conditions. A de minimis condition is defined by ASTM Standard E1527-13 as:

“A condition that generally does not present a threat to human 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.”

1.2 SCOPE OF SERVICES The scope of services was defined by our proposal dated July 2, 2020 (Appendix B). The scope included a regulatory database review, historical and physical records review, interviews, visual noninvasive reconnaissance of the Property and adjoining properties, compilation and evaluation of data, and preparation of this report. No special terms and conditions were incorporated into this Phase I ESA.

1.3 SIGNIFICANT ASSUMPTIONS Tetra Tech assumes the following:

That the User will read this report in its entirety. That all information obtained from others in relation to the Property is correct and complete. That the User and/or the current Property owner and/or occupant(s) have provided Tetra Tech with all

reasonably ascertainable prior environmental information available concerning the Property.


2 August 4, 2020

2.0 RELIANCE, LIMITATIONS AND DATA GAPS

2.1 RELIANCE This report is an instrument of service of Tetra Tech and includes limited research, a review of specified and reasonably ascertainable information and a Property reconnaissance to identify RECs in general accordance with ASTM Standard E 1527-13. Tetra Tech’s Phase I ESA was performed in accordance with generally accepted practices of the profession undertaken in similar studies at the same time and in the same geographical area, and Tetra Tech observed that degree of care and skill generally exercised by the profession under similar circumstances and conditions.

The scope of services and the report have been completed on behalf of and for the exclusive use of the User, solely for their use and reliance in the assessment of this Property. The User is the only party to which Tetra Tech has explained the risks involved and which have been involved in the shaping of the scope of services needed to satisfactorily manage those risks, if any, from the User’s point of view.

Accordingly, reliance on this report by any other party may involve assumptions whose extent and nature lead to a distorted meaning and impact of the findings and opinions related herein. Tetra Tech’s findings and opinions related in this report may not be relied upon by any party except the User without the consent of the User and Tetra Tech. Tetra Tech may be available to contract with other parties to develop findings and opinions related specifically to such other parties’ unique risk management concerns related to the Property.

2.2 LIMITATIONS This report was prepared for the sole use of the User (as described in Section 1 above). The reliance on and use of this report by the User shall be governed exclusively by the limitations and exceptions found in the report and the terms of the existing Consulting Services Agreement between H H and Tetra Tech. This report was prepared based on review of limited data, as described herein, in accordance with generally accepted professional practices, applicable to work of similar nature and complexity of similar localities, at the time the services were performed. No warranty, expressed or implied, is made. The scope of this report is limited in nature and intended to provide a preliminary evaluation of the current readily observable/obvious environmental conditions at the Property at the time of the report preparation and does not constitute definitive or in-depth review of all the potential environmental impairments and situations. Tetra Tech assumes no responsibility for conditions of which it is unaware and/or as to which there was no opportunity or request for review.

It is important to recognize that even the most comprehensive scope of services may not detect all the environmental liabilities at a particular property. Therefore, nothing herein shall be construed as a representation or certification that the property is either fully characterized or is free of environmental impairments and/or contamination.

In order to conduct the investigation for this report, Tetra Tech relied upon readily available information, as discussed in the report, and unless explicitly included in our scope, included no verification of the accuracy or completeness of documentation or data or possible withholding of information by the interviewees, agencies, or other parties.

2.3 DATA GAPS ASTM E1527-13 defines a data gap as:

“A lack or inability to obtain information required by this practice despite good faith efforts by the environmental professional to gather such information. Data gaps may result from


3 August 4, 2020

incompleteness in any of the activities required by this practice, including but not limited to site reconnaissance…and interviews.”

The following data gap was encountered for this Phase I ESA and was determined to be non-significant:

The Sanborn Map Report provided by EDR indicated the Property was unmapped; The Tax Map and Building Permit Reports provided by EDR indicate no coverage for the Property; and, Property deeds/titles were not provided to Tetra Tech by the User. Sheridan County Montana does not

offer online access to property documents.

4.0 PROPERTY LOCATION AND DESCRIPTION

The Property is a nearly rectangular shaped parcel located at 4943 Highway 16 South, approximately one-third mile north of Antelope, Sheridan County, Montana. According to the Montana Cadastral website (http://svc.mt.gov/msl/MTCadastral), the Property encompasses 30.01 acres and includes two buildings (a 12,338 square feet shop/office building and a 9,000 square feet storage building), a gravel laydown yard (approximately 15 acres), an aboveground fueling system, and approximately 15 acres of agricultural land located east of the Northern Oilfield Services facility. The legal description of the Property is: Section 13, Township 34 North, Range 55 East, C.O.S. 484933, ACRES 30.01, TRACT IN SE4 AS IN BK 1, PG 586, CONT 30.01 AC SERVICE SHOP.

The Property is located along the east side of Montana Highway 16 in an agricultural area north of Antelope, Montana. The Property is adjoined to the north and south by cultivated farmland, to the west by Highway 16 South with a railroad track beyond, and to the east by Spoklie Road with farmland beyond; a farmstead is located northeast of the Property.

The term “adjoining property,” as defined by the ASTM Standard, means properties which border or are contiguous or partially contiguous with the property, or would be so but for a street, road, or other public thoroughfare separating them.

6 August 4, 2020

5.0 PHYSICAL SETTING

The physical setting of the Property was reviewed using published reports and maps depicting topography, soil, hydrogeology and geology. The information is useful in evaluating contaminant movement in the environment.

5.1 TOPOGRAPHY The United States Geological Survey (USGS) 7.5-minute topographic quadrangle of Antelope (2014) indicates the Property is located on nearly level terrain along the Highway 16 corridor, approximately one-third mile north of Antelope, Montana. Antelope is situated on the edge of the Big Muddy Creek valley, which is a tributary to Missouri River. The surface elevation of the Property is approximately 2,055 feet above mean sea level. Regionally, the surface topography gently slopes to the south following Big Muddy Creek, which is located approximately 0.9 miles west of the Property.

5.2 SOIL CONDITIONS According to the United States Department of Agriculture, Natural Resources Conservation Service (USDA-NRCS) web soil survey obtained online, the surface materials at the Property are classified as William-Zahill loams with slopes between zero and four percent. According to the NRCS official soil series description, these series consists of very deep, well drained, moderately slow or slowly permeable soils formed in calcareous glacial till. These soils are found on glacial till plains and moraines (USDA-NRCS, 2020).

5.3 GEOLOGY The stratigraphy in northeast Montana generally consists of alluvium, terrace, and glacial deposits which overly the bedrock of the Fort Union Formation. Continental glaciers extended into this region during several episodes of glaciation leaving deposits of till and outwash materials mantling the bedrock. The Property is underlain by the Tertiary Lebo Member of the Fort Union Formation. The Lebo Member is composed of dark gray carbonaceous shale, bentonitic claystone, sandstone and coal, and is found on alluvial plains (Vuke et. al., 2007). The surface geology at the Property consists of Pleistocene age glacial till (Colton et. al., 2006). The till is tough and compact when dry, but plastic when wet. It is a highly impermeable, calcareous, unstratified and unsorted, unconsolidated to moderately consolidated, heterogenous mixture. It is predominantly clay, but also includes silt, sand, pebbles, cobble, and boulders. A well log for a domestic well drilled on the Property indicates that the Property is underlain by approximately 50 feet of till, followed by interbedded gravel, sand and clay material.

5.4 HYDROGEOLOGY In northeast Montana, alluvial and outwash channel aquifers form shallow flow systems perched on bedrock beneath the Missouri, Poplar, Big Muddy and numerous tributary valleys (Donovan, 1988). The glacial till in this region is generally a poor aquifer material because of its low permeability; however, the sand and gravel in buried outwash channels and lenses between till units transmits water and are important aquifers.

Groundwater at the Property likely follows the local drainage patterns and flows to the southwest. The Montana Bureau of Mines and Geology Groundwater Information Center (GWIC) online database (http://mbmggwic.mtech.edu/) was searched for wells within the vicinity of the Property. Static water levels measured in wells located near the Property ranged from approximately forty-five to eighty feet below ground surface (bgs). Static water level was not reported for the on-site well.

6.0 HISTORICAL USE RECORDS REVIEW

Historical use information for the Property and adjoining properties was obtained by reviewing reasonably ascertainable historical sources listed below. Uses of the Property are referenced from the present back until 1949. The EDR historical reports are presented in Appendix C.

6.1 SANBORN FIRE INSURANCE MAPS In the late nineteenth century, the Sanborn Company began preparing maps for use by fire insurance companies. These maps indicate construction materials of specific structures in developed urban areas. Sanborn maps were periodically updated and expanded geographically through the twentieth century. Tetra Tech contracted with EDR to perform a search for historical Sanborn Maps for the Property. The EDR Certified Sanborn Map Report indicates that the Property is unmapped.

6.2 TOPOGRAPHIC MAPS Tetra Tech reviewed historical topographic maps provided by EDR. A summary of the review is presented below.

Table 2 – Topographic Map Summary

Year Description

1949

No buildings exist on the Property. Highway 16 borders the Property to the west and Spoklie Road to the east. Multiple structures are indicated on a farmstead to the northeast of the Property. The Burlington Northern Railroad runs north/south along the west side of Highway 16, Big Muddy Creek is located further to the west. The town of Antelope is indicated to the south of the Property.

1988 The only notable changes from the previous map are the addition of structures to the farmstead northeast of the Property and in the town of Antelope.

2014 No significant changes from the previous map are apparent.

6.3 AERIAL PHOTOGRAPHS Tetra Tech contracted with EDR to perform a search of historical aerial photographs. EDR provided eight historical aerial photographs from between 1974 and 2017.


8 August 4, 2020

Table 3 – Aerial Photograph Summary

Date Description

1974

The Property appears to be cultivated agricultural land. However, this image pixilates upon magnification and so details are indiscernible. All adjoining properties are agricultural in use. A farmstead with associated buildings is located on the adjoining property to the northeast. Highway 16 is visible to the west.

1980 This image pixilates upon magnification and so details are indiscernible. No significant changes from the previous photograph are apparent.

1983 This image pixilates upon magnification and so details are indiscernible. No significant changes from the previous photograph are apparent.

1996 No significant changes from the previous photograph are apparent.



2013

The Property has been developed into its current configuration. The shop/office building, storage building, laydown yard, fueling area, and agricultural field (east side of site) are visible. Additionally, a row of storage tanks can be seen extending down the center line of the Property. Two rows of trailers have been parked in the northeast corner of the Property.

2017 The east half of the Property is once again strictly agricultural in use (trailers have been removed). The tanks have been removed from the center line of the Property. The west half of the Property appears similar to the previous photograph.

6.4 CITY DIRECTORIES City directories (e.g. Polk City Directory and Cole Information Services) include listings of residents, businesses and professional concerns organized both alphabetically by name similar to a telephone book, and alphanumerically by street name, then specifically by street address. Tetra Tech contracted with EDR to perform a search of historical city directories for the Property and vicinity.

The Property was not listed in the EDR City Directory Image Report. Occupants for address near the Property were dominantly residential. However, Rocky Ridge Wrecking was indicated at an address approximately two miles north of the Property.

6.5 OWNERSHIP INFORMATION The most recent land title deep was included in the EDR Environmental Lien and AUL Search report. A warranty deed dated November 16, 2012 indicates that the Property was transferred from Northern Oilfield Services, Inc. to H H Land & Livestock LLC. No additional deeds were available as Sheridan County does not have a public, online database.

6.6 ENVIRONMENTAL CONCERNS RELATED TO HISTORICAL USE Based on the review of historical records for the Property and adjoining properties, no RECs were identified for the Property.


9 August 4, 2020

7.0 REGULATORY REVIEW

The purpose of the regulatory review is to obtain and review reasonably ascertainable records that will help identify RECs that could affect the Property. Tetra Tech contracted with EDR to conduct a search of ASTM Standard-required Federal, state, tribal and local environmental databases. The ASTM Standard-required minimum search distance (MSD) for each database is listed below. A copy of the EDR Radius Map report is included in Appendix C.

The Property was not identified by the EDR database search. Facilities identified within the MSD are summarized in the following table and discussed below.

8.0 SITE RECONNAISSANCE

The objective of the site reconnaissance is to obtain information indicating the likelihood of identifying ASTM RECs in connection with the Property to the extent not obstructed by bodies of water, adjacent buildings, or other obstacles. The Property and adjoining properties were visually observed by Tetra Tech Environmental Professional Scott Ross on July 17, 2020. Mr. Ross was accompanied by Bart Horner, owner of Northern Oilfield Services. Adjoining properties were visually observed for potential RECs from legally accessible rights-of-way. Figure 2 and 3 in Appendix A presents a detail map of the Property and vicinity and Property photographs are included in Appendix D.

8.1 PROPERTY OVERVIEW AND CURRENT USES

8.1.1 Property Overview and Current Uses The Property is a nearly rectangular shaped parcel located at 4943 Highway 16 South, approximately one-third mile north of Antelope, Sheridan County, Montana. The Property encompasses 30.01 acres, the western half is occupied by Norther Oilfield Services (a User of this ESA) and the eastern half is used for dryland farming. Two buildings (a 12,338 square feet shop/office building and a 9,000 square feet storage building), a gravel laydown yard (approximately 15 acres), and an aboveground fueling system are located on the west half of the Property. Northern Oilfield Services is in the process of vacating the facility and has staged their equipment in the buildings and yard for an upcoming auction.

8.1.2 Description of Specific Property Features Topographic Observations

The surface elevation of the property is approximately 2,055 feet above mean sea level. Topographically, the Property is relatively flat with a gentle slope away from the shop/office building

Source of Drinking Water

Drinking water is provided by Dry Prairie Rural Water.

Sewage Disposal/Septic System

The Property has an on-site septic system, the septic tank is located off the southeast corner of the shop and the drainfield extends to the southwest corner of the Property. The septic system contains four tanks which allow for an oil-water separator and sand filter system.

Hazardous Substances and Petroleum Products Associated with Operations Other Than Storage Tanks

Various fluids associated with equipment operation and maintenance (e.g. lubricants, hydraulic fluid, coolant, cleaners, etc.) were observed inside the buildings. The sizes of the containers range from retail-sized to drums and totes. Most of the containers are inside the buildings which have concrete slab foundations. Minimal de minimis staining was observed at the base of a rack that holds the totes (lubricants, hydraulic fluid and washer fluid).

Off the southeast side of the shop/office building is a Conex container where containers of used oil are stored before being transferred offsite for disposal. Adjacent to the Conex container is a tote of used antifreeze which is awaiting offsite disposal. Next to this tote was an empty 55-gallon drum, this drum has since been disposed at the landfill. Two other drums were observed on the east side of the storage building, these drums contain lubricants. Neither the drums nor the tote were placed on secondary containment. No staining was observed on the gravels at the base of the Conex trailer, tote or drums.


12 August 4, 2020

Storage Tanks and Associated Equipment

Two, double-walled, 10,000-gallon aboveground storage tanks (ASTs) were observed south of the shop/office building. The tanks contain diesel and gasoline and are installed on a concrete pad. There are three fuel dispensers on the concrete pad for dyed diesel, regular diesel, and unleaded gasoline. No petroleum stains were observed on the concrete pad or the gravel surface around the concrete pad.

Odors

No unusual or petroleum product odors were noted on the Property.

Interior and Exterior Surficial Staining or Corrosion and Stressed Vegetation

De minimis interior staining was observed beneath a rack that held totes of lubricants and other automotive fluids. Exterior de minimis staining was noted in the covered storage area along the east side of the shop/office building and on a concrete pad that previously contained a heater treater. The staining associate with the heater treater was limited to the concrete pad and no impacts to the surrounding gravel was noted.

The staining beneath the covered storage area on the east side of the shop/office building was from leaking equipment. The largest area of staining was from a hydraulic fluid leak. On July 23, 2020, Northern Oilfield Services personnel excavated the soils to a depth of approximately two feet bgs, when oil impacts were no longer evident. The soils were disposed of at the county landfill and the excavation was backfilled and regraded. All other de minimis stains in this area were also remediated in this manner. It should be noted that Tetra Tech did not provide oversite or confirmation sampling for these remediation activities. However, given the low mobility of hydraulic fluid and the small quantity released (less than what would be subject to regulatory compliance), this is considered a de minimis condition.

Drums and Other Containers of Unknown Contents

No drums or containers of unknown contents were observed on the Property.

PCBs

Two, new transformers were observed on the Property. These transformers were in like-new condition with no visible rust or leaks.

Heating and Cooling Systems

The shop/office building is heated with an in-floor heating system and electric space heaters and cooled by a forced-air system. The storage building is not climate controlled.

Drains and Sumps

Three floor drains were observed in the shop/office building. The vehicle storage bay and wash bay each had trench style drains, these drains accepted snow melt (from vehicles) and wash water, respectively. There is also a floor drain in the mechanic bay, this drain accepts snow melt from vehicles. All the floor drains discharge to the septic system. Given that the septic system receives grey water from the floor drain system, a Class V Underground Injection Control (UIC)Permit is required for the system. Northern Oilfield Services could not produce the permit when asked.

Pits, Ponds, or Lagoons

No pits, ponds or lagoons were observed on the Property.

Solid Waste Disposal

Solid waste is removed from the Property by Plentywood Sanitation.


13 August 4, 2020

Wastewater Discharges

Wastewater is not discharged from the Property.

Wells

One well was observed on the Property. It is located off the northeast corner of the shop/office building. Northern Oilfield Services used this well to fill water tanks.

8.2 ADJOINING PROPERTY OBSERVATIONS The Property is located along the east side of Montana Highway 16 South in an agricultural area north of Antelope, Montana. The Property is adjoined to the north and south by cultivated farmland, to the west by Highway 16 South with a railroad track beyond, and to the east by Spoklie Road with farmland beyond; a farmstead is located northeast of the Property.

8.3 ENVIRONMENTAL CONCERNS IDENTIFIED THROUGH SITE RECONNAISSANCE Based on Tetra Tech’s site reconnaissance of the Property and adjoining properties, no RECs were identified.


14 August 4, 2020

9.0 INTERVIEWS

Tetra Tech personnel contacted individuals familiar with the Property to obtain information indicating potential RECs in connection with the Property. A summary of the correspondence is presented below.

9.1 INTERVIEWS Bart Horner, Owner of H H Land & Livestock / Northern Oilfield Services

Mr. Bart Horner was interviewed during the site reconnaissance and during a telephone call on July 29, 2020. Mr. Horner purchased the Property from Rom and Patti Hedges, the Property had been in their family for decades and had always been used for dryland farming. The east half of the Property is farmed by a local farmer and is currently planted with durum wheat. Mr. Horner was asked about the use of solvents and explained that the shop does not and has not ever used a parts washer. To his knowledge, the brake cleaner is the only product on site that could contain a solvent. When asked about chemical/oil disposal practices he indicated that the used oils are stored in the Conex container and are transferred offsite to be burned in an oil burning furnace. Additionally, used antifreeze is awaiting disposal from Safety-Kleen (a waste disposal company). He stated that chemicals or petroleum products are not disposed of in the floor drain systems. Mr. Horner also stated that when necessary, (one to four times a year) the oil-water separator and filter chambers of the septic tank are cleaned out with a vacuum truck and disposed of offsite. Mr. Horner over saw the removal of the hydraulic fluid impacted gravels in the covered area east of the shop/office building. He stated that the final excavation was approximately 26-inches deep and four feet in diameter. Mr. Horner is not aware of any environmental concerns associated with the Property.

9.2 ENVIRONMENTAL CONCERNS IDENTIFIED THROUGH INTERVIEWS No environmental concerns or RECs were identified during the interview.

10.0 VAPOR ENCROACHMENT CONDITIONS

Tetra Tech performed a Tier 1 Vapor Encroachment Screening (VES) to evaluate the potential for a vapor encroachment condition (VEC) to exist at the Property. The VES was performed based on ASTM E2600-10, Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions and using EDR’s VEC Worksheet (Appendix E). The VES was performed by reviewing all physical, historical, regulatory, site reconnaissance, and interview information obtained during this Phase I ESA.

As discussed in Section 5.0, the soil, geologic, and hydrogeologic conditions in the area of the Property are conducive to mobilization of fluids and vapors vertically and horizontally at the surface and in the subsurface due to the nature of the materials (from clayey to fine textures and coarse materials). The only likely underground utility is for Dry Prairie Rural Water, which likely runs Highway 16 South. A release near the utility corridors could result in the migration of fluids and/or vapors along this line that could result in plume migration, including vapor migration.

EDR’s VEC Worksheet tool was used to support Tetra Tech’s VES. The VEC Worksheet helped identify facilities with known releases and historical gasoline stations, dry cleaners, and government archived facilities that may use, store, or generate petroleum products or hazardous substances currently or may have in the past.

The VEC Worksheet tool includes considerations such as:

Known or potential releases; Chemical type; Hydrogeologic and geologic conditions of the area; Topography; Utility corridors; and Plume characteristics for known releases.

The VEC Worksheet did not identify any facilities in the vicinity that present a potential for vapor migration.


16 August 4, 2020

11.0 CONCLUSIONS AND RECOMMENDATIONS

Tetra Tech has completed a Phase I ESA of the Property located at 4943 Highway 16 South in Antelope, Sheridan County, Montana. The work was conducted in accordance with our proposal dated July 2, 2020 and in general accordance with the scope and limitations of ASTM Standard E1527-13.

Based on the foregoing assessment, evidence of RECs were not identified. It is Tetra Tech’s professional opinion that further investigation of the Property is not warranted at this time. However, a septic system that receives water from floor drains requires a Class V UIC Permit from the U.S. EPA. This is a regulatory compliance issue that needs to be addressed.

EDR BUILDING PERMIT REPORT

About This Report

The EDR Building Permit Report provides a practical and efficient method to search building department records for indications of environmental conditions. Generated via a search of municipal building permit records gathered from more than 1,600 cities nationwide, this report will assist you in meeting the search requirements of EPA’s Standards and Practices for All Appropriate Inquiries (40 CFR Part 312), the ASTM Standard Practice for Environmental Site Assessments (E 1527-13), or custom requirements developed for the evaluation of environmental risk associated with a parcel of real estate.

Building permit data can be used to identify current and/or former operations and structures/features of environmental concern. The data can provide information on a target property and adjoining properties such as the presence of underground storage tanks, pump islands, sumps, drywells, etc., as well as information regarding water, sewer, natural gas, electrical connection dates, and current/former septic tanks.

ASTM and EPA Requirements

ASTM E 1527-13 lists building department records as a "standard historical source," as detailed in § 8.3.4.7: “Building Department Records - The term building department records means those records of the local government in which the property is located indicating permission of the local government to construct, alter, or demolish improvements on the property.” ASTM also states that “Uses in the area surrounding the property shall be identified in the report, but this task is required only to the extent that this information is revealed in the course of researching the property itself.”

EPA’s Standards and Practices for All Appropriate Inquires (AAI) states: "§312.24: Reviews of historical sources of information. (a) Historical documents and records must be reviewed for the purposes of achieving the objectives and performance factors of §312.20(e) and (f). Historical documents and records may include, but are not limited to, aerial photographs, fire insurance maps, building department records, chain of title documents, and land use records.”

Methodology

EDR has developed the EDR Building Permit Report through our partnership with BuildFax, the nation’s largest repository of building department records. BuildFax collects, updates, and manages building department records from local municipal governments. The database now includes 30 million permits, on more than 10 million properties across 1,600 cities in the United States.

The EDR Building Permit Report comprises local municipal building permit records, gathered directly from local jurisdictions, including both target property and adjoining properties. Years of coverage vary by municipality. Data reported includes (where available): date of permit, permit type, permit number, status, valuation, contractor company, contractor name, and description.

Incoming permit data is checked at seven stages in a regimented quality control process, from initial data source interview, to data preparation, through final auditing. To ensure the building department is accurate, each of the seven quality control stages contains, on average, 15 additional quality checks, resulting in a process of approximately 105 quality control “touch points.”

For more information about the EDR Building Permit Report, please contact your EDR Account Executive at (800) 352-0050.

SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest underthe Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP,renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site whileit is archived if site conditions change and/or new information becomes available. Archived sites have been removedand archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge,assessment at a site has been completed and that EPA has determined no further steps will be taken to list thesite on the National Priorities List (NPL), unless information indicates this decision was not appropriate orother considerations require a recommendation for listing at a later time. The decision does not necessarily meanthat there is no hazard associated with a given site; it only means that. based upon available information, thelocation is not judged to be potential NPL site.

EPA WATCH LIST: EPA WATCH LISTEPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcementmatters relating to facilities with alleged violations identified as either significant or high priority. Beingon the Watch List does not mean that the facility has actually violated the law only that an investigation byEPA or a state or local environmental agency has led those organizations to allege that an unproven violationhas in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the allegedviolations that were detected, but instead indicates cases requiring additional dialogue between EPA, state andlocal agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

EDR MGP: EDR Proprietary Manufactured Gas PlantsThe EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’sto produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixtureof coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compoundsare potentially hazardous to human health and the environment. The byproduct from this process was frequentlydisposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soiland groundwater contamination.

Project Manager for a Due Diligence study to assist Oasis Petroleum in the acquisition of a 55,000 net acres lease with approximately 226 operating drilling locations and 29 central tank batteries in the Bakken region of North Dakota and Montana. The field activities, an estimate of current environmental liability, and a report summarizing the findings were completed in three weeks. For the field activities, Tetra Tech conducted electromagnetic (EM) resistivity surveys of five salt water disposal well sites which were initially included in the sale, technologically enhanced naturally occurring radioactive material (TENORM) surveys of all tanks, and field observations of spills, leaks, and regulatory compliance of standard spill prevention control and countermeasure (SPCC) items. All field data was compiled on tablet computers which were then directly uploaded onto a SharePoint site. This allowed the client to track progress and upload additional equipment observations made concurrently by their staff. Additionally, current air quality permitting compliance was evaluated by Senior Tetra Tech Air Quality experts leading to evaluations of current compliance status.

Red Eagle Stores, Wyoming. Prepared Phase I ESAs on seven retail refueling facilities for potential purchase. These Phase I ESAs were all completed in three weeks. Investigations included research at Wyoming state offices for UST compliance and compliance history.
