Identify the site’s history, water and discharge arrangements, records and proposed changes. A general industry guide cannot establish environmental compliance or the protections available in a specific transaction.
Begin with prior use and the property file
Gather historical-use information, site plans, relevant reports, notices and records of tanks or other potential concerns. Tell the environmental professional what is known and unknown. An apparently clean operating site may still need assessment of its history.
EPA’s all-appropriate-inquiries resources provide assessment background. Counsel and the professional should determine the required scope and process for the transaction rather than relying on a generic checklist or a broker’s cost estimate.
Document the water and wastewater operation
Identify the utility, responsible sewer/discharge authority, treatment/reclaim systems and operating records. Ask which approvals and conditions apply to the current use. Verify requirements directly for the actual parcel.
Do not treat reclamation as interchangeable with compliance. EPA’s vehicle-wash guidance explains water-management practices, but installation condition and local requirements still need professional review.
Evaluate proposed alterations separately
A format change, equipment upgrade, expansion or new service can alter layout, utilities or discharge. Obtain the relevant engineering and authority review before forecasting the project. Existing operations do not automatically authorize every proposed change.
Use written estimates for required work and clarify responsibility in the transaction. Distinguish a recommendation, an approval and a binding condition; they do not mean the same thing.
Use findings in price and closing decisions
Maintain an issue register with report, reviewer, scope, unresolved items and next steps. Ask counsel about representations, conditions and continuing exposure. A buyer should understand the environmental decision before agreeing to unconditional terms.
