Keystone Environmental’s contaminated sites professionals successfully complete projects from the simplest Phase I ESA to the most complex remediation, with costs ranging from a few thousand to tens of millions of dollars. Our tools are the common industry tools but our approach is focused on the client end game. Our successes speak to our drive to achieve desired results. We have completed contaminant investigations, risk assessments and remediation at sawmills, OSB and plywood mills, pulp mills, foundries and casting plants, steel rolling mills, chemical refineries, mine sites, rail yards, shipyards, airports, wood treating plants, and hazardous waste processing facilities.
- Phase I/II Environmental Site Assessments/Stage 1 & 2 Preliminary Site Investigations
Whether a real estate transaction or purchase/divestiture of an industrial complex, the Phase I/Stage 1 is relied on to identify potential risks and to support financing. Our dedicated team completes over 400 Phase I’s annually and have the necessary expertise and experience to identify potential risk at small commercial properties to complex industrial facilities. And with that level of experience over a quarter century, we know how to focus in on real issues, those with potential material effect. A Phase II/Stage 2 Preliminary Site Investigation is recommended when the potential risk may be material to our client. We scope our preliminary investigations to satisfy the material needs of our clients; scoping investigations to reflect risk reduction and quantification that reflects the risk tolerance of each client.
- Detailed Site Investigations
Detailed investigations provide the information needed to satisfy the regulatory requirements. More importantly, they provide the information that enables consideration of remediation options and quantification of liability. Planning and executing the detailed investigation requires anticipation of how the contamination may be remediated or managed. Only in this way do we ensure we collect the data that will be needed to assess the remediation option, complete the detail engineering design and complete a detailed investigation. With nearly 30 years of experience over thousands of projects, and with staff retention over decades, we are able to anticipate what information we may need to determine the solution that best fits our clients’ needs.
- Contaminant Remediation
The remediation strategy or approach must serve the site-specific needs of the client. That means for site development, the development form is a key factor in selecting an appropriate remediation strategy. Where site or facility closure is the objective, a risk management plan based on a detailed Human Health and Ecological Risk Assessment often drives the remediation strategy. Remediation strategy development is a team approach including the client, contaminated site investigation specialists, professional engineers, and risk assessors. We have completed remediation and secured regulatory closure at chemical refineries, shipyards, landfills, pulp mills, sawmills, and a sundry of commercial properties such as dry cleaners and service stations.
- Human Health and Ecological Risk Assessment
While the risk assessment identifies unacceptable risks to human health and the ecology, it also needs to identify the specific factors that are driving those unacceptable risks. That is a key focus for our risk assessment professionals. Developing site-specific toxicity reference values, we have enabled remediation cost reductions of over 75%, representing millions of dollars, by demonstrating that while standards are exceeded, the contaminants are not presenting an unacceptable risk. Similarly, the risk assessment team can provide data that then enables our engineers to design site-specific risk management measures enabling regulatory approval. We have applied risk assessment and risk management to achieve closure of pulp mills, chemical refineries, shipyards, dry cleaners and service stations, mine sites, and marine sediment off industrial facilities.
