Warehouse Safety By Design Pt 2: Environmental Due Diligence

When it comes to "Warehouse Safety By Design" and the complex task of siting a new warehouse, the first and most crucial step in ensuring long-term success is making sure the location is not only optimal for business operations but also free from environmental risks. Environmental due diligence is a critical part of this process, as it helps identify potential contamination and liabilities before they become costly problems. The process includes multiple layers of investigation, each designed to uncover risks and allow for appropriate action to mitigate them. In this blog, we’ll review the essential elements of environmental due diligence, explaining each phase of the Environmental Site Assessment (ESA) process, what potential environmental risks to look out for, and how to ensure your future warehouse site is safe and compliant.

In the context of acquiring a new warehouse location, environmental due diligence is essential to assuring "Warehouse Safety By Design." Environmental due diligence requires a thorough evaluation of the site’s environmental condition to ensure that there are no hidden risks, such as contamination from hazardous materials or previous industrial activities. By conducting environmental due diligence, businesses can uncover potential problems before committing to a site, protecting themselves from future liabilities and ensuring they are compliant with federal, state, and local environmental regulations.

One of the core components of environmental due diligence is the Environmental Site Assessment (ESA). The ESA process is typically broken down into two stages: Phase I ESA and Phase II ESA. If contamination is identified during the Phase II ESA, a Phase III ESA may follow, which involves remediation efforts. Let’s walk through each of these stages to see what they entail.

Phase I Environmental Site Assessment (ESA): The First Step

The Phase I ESA is a non-invasive assessment aspect of "Warehouse Safety By Design" as the process identifies potential contamination and environmental liabilities at a given site. This phase primarily involves a combination of visual inspections, historical research, and data collection, which together help identify whether a site is free of environmental hazards or if further investigation is required.

1. Site Inspection

The first step in a Phase I ESA is a visual inspection of the property and its surrounding area. Trained environmental professionals walk the site to look for signs of contamination, such as the presence of hazardous materials, polluted soil, or standing water that may suggest hazardous chemical runoff. This inspection also focuses on identifying any obvious concerns like leaking pipes or underground storage tanks (“USTs”).

2. Historical Research

Understanding the history of a site is crucial for identifying potential risks. In the Phase I ESA, professionals review old maps, aerial photos, and property records to identify previous uses of the land. If the property has been used for industrial purposes in the past, there may be a higher likelihood of contamination. This stage also involves reviewing environmental databases that track hazardous chemicals or waste, and potential pollution sources.

3. Interviews

During this phase, interviews with current and former property owners, tenants, and local authorities are conducted. These conversations help gather firsthand information about the site’s past activities and uncover any environmental issues that may not be readily visible during an inspection. Speaking to people who are familiar with the property can often uncover hidden concerns that otherwise wouldn’t have been identified. Property owner/user documents are also reviewed.

4. Database Search

A critical component of the Phase I ESA is the search of various environmental databases. These databases track records of contamination, including information on leaking USTs, hazardous waste sites, or historical environmental violations. By consulting these resources, environmental professionals can determine whether the property has been previously involved in activities that may pose a risk to human health or to the environment.

5. Due Diligence Report

Finally, all findings from the site inspection, historical research, interviews, and database search are compiled into a comprehensive report. This report identifies any Recognized Environmental Conditions (RECs) – i.e. any conditions that suggest the presence of contamination or environmental risk(s). If no major issues are identified, the Phase I ESA report is typically enough to move forward with the acquisition, subject to other aspects of general due diligence. 

Phase II Environmental Site Assessment (ESA): The Deep Dive

If the Phase I ESA uncovers potential contamination or other environmental risks, the next step is a Phase II ESA. The Phase II assessment involves more detailed sampling and analysis to confirm the presence of contaminants and determine their presence and scope. Unlike the Phase I ESA, which is largely observational, the Phase II ESA is invasive and includes physical testing of the site.

1. Sampling

During the Phase II ESA, various samples are collected from the site, such as from soil, groundwater, air, and surface water. These samples are tested for contaminants like petroleum products, heavy metals, or other hazardous substances. The purpose is to understand the nature and extent of any contamination that may exist. Oftentimes, soil samples may require drilling.

2. Laboratory Analysis

Once the samples are collected, they are sent to a laboratory for analysis. The laboratory tests the samples to measure contamination levels, comparing them to established environmental, health, and safety standards. This step is critical for understanding whether the site poses a health risk to future employees, the community, or the surrounding environment.

3. Focused Investigation

If contamination is suspected in specific areas (such as near USTs or areas where chemicals were previously stored), a Phase II ESA may involve focused investigations of these particular zones. This deeper analysis helps pinpoint the exact sources of contamination, guiding future remediation efforts if necessary.

Phase III ESA: Remediation and Cleanup

If the Phase II ESA identifies significant contamination, the site may require remediation - a cleanup process that aims to restore the property to a safe and usable condition. In such cases, a Phase III ESA may be initiated. This phase involves actual remediation efforts, which could range from soil removal to groundwater treatment, depending on the type and extent of contamination.

For example, if hazardous chemicals or petroleum products are found in the soil, remediation may involve removing the contaminated soil and replacing it with clean fill. If the groundwater is contaminated, it may require treatment using various technologies to remove hazardous chemicals or substances.

Key Compliance Considerations

Beyond the ESA process, there are a number of critical compliance considerations that must be addressed when acquiring a warehouse site.

1. Federal, State, and Local Regulations

Each warehouse site must comply with various environmental regulations, including those established by federal, state, and local authorities. These regulations often govern how hazardous materials are handled, stored, and disposed of, as well as how contamination should be managed. A key regulatory body to consider is the Environmental Protection Agency (EPA), which oversees enforcement of the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”).

2. National Priorities List (“NPL”)

Another important consideration is whether the site is listed on the EPA’s National Priorities List (NPL), which tracks hazardous waste sites that pose a significant risk to human health or the environment. If a site is on this list, it is a red flag that may require substantial remediation before it can be used for warehouse purposes.

3. Liabilities and Potential Risks

Even if a site does not show immediate signs of contamination, it’s essential to assess any potential liabilities that could arise in the future. For example, older property uses or buildings may have contained hazardous materials like asbestos, hazardous chemicals, or lead piping or paint. It’s important to ensure such risks are managed through proper testing, removal, or containment before the site is used. "Warehouse Safety By Design" also means environmental compliance in order to avoid environmental exposures that can lead to regulatory exposures and legal liabilities.

Why Environmental Due Diligence Matters

The importance of environmental due diligence to effect "Warehouse Safety By Design" cannot be overstated. Failing to identify and address environmental risks early in the process can result in costly cleanup efforts, fines, and delays in warehouse operations, construction or building modification. Environmental contamination can also pose serious health risks to employees, local communities, and the surrounding ecosystem.

Incorporating environmental due diligence into warehouse site selection helps businesses avoid these risks and ensures that their facilities are built and operated upon safe, sustainable land. Furthermore, environmental responsibility is a growing concern for investors, customers, and regulatory agencies. Demonstrating that you’ve conducted thorough due diligence shows that you’re committed to sustainability and corporate responsibility - traits that are increasingly valued in today’s market.
