Strata Environmental

What Strata Environmental does

Strata Environmental Services is a privately-held environmental consulting firm headquartered in Knoxville, Tennessee, founded in 1992 by Charles W. Ferst, P.E. The firm provides professional environmental services to commercial, industrial, governmental, and legal clients, with a service portfolio spanning environmental due diligence (Phase I assessments per ASTM standards), air quality permitting and modeling, multimedia compliance assistance, site investigation and remediation (including Superfund and RCRA work), and energy management and greenhouse gas emissions. Projects have been executed across the United States, Canada, South America, and Europe, with named engagements covering oil and gas pipelines, refineries, foundries, glass manufacturers, Class-1 railroads, healthcare portfolios, and large multi-facility manufacturing programs. The firm emphasizes principal-led engagement teams staffed by senior engineers and scientists, drawing on the founder's 35+ years at U.S. EPA and Department of Interior and the current leadership team's 20-25 years of consulting experience.

Complementing its consulting practice, Strata offers EiOS, a proprietary web-based environmental and safety information management system that supports multi-facility compliance tracking, document management, SARA reporting, and tiered user access. The firm also produces StrataGuides — laminated fact sheets on topics such as storm water, EPCRA, HazCom, ISO 14001, and facility vulnerability assessment — that function as a top-of-funnel content asset. Revenue is generated through project-based professional services engagements quoted on a per-project basis, with no publicly disclosed pricing. Following the death of founder Charles W. Ferst on May 20, 2022, leadership transitioned to Kevin D. Parr (President) and Jennifer F. Parr (Executive Vice President and COO), both Virginia Tech-trained P.E.s with long tenures at the firm. The company operates with no disclosed outside investment, no funding rounds, and no M&A activity, consistent with a closely-held, mature small professional services firm.

Core offering

Strata Environmental provides professional environmental consulting services to commercial, industrial, and governmental clients, delivering environmental due diligence assessments, air quality permitting and modeling, multimedia compliance assistance, site investigation and remediation, and energy and greenhouse gas management. The firm complements its consulting practice with EiOS, a proprietary web-based compliance management software that tracks environmental and safety data across single or multi-facility operations, and with StrataGuides, laminated reference fact sheets on regulatory topics such as Storm Water, EPCRA, HazCom, and ISO 14001. Engagements are staffed with principal-led, senior technical teams and tailored to each client's regulatory and operational demands.

Product overview

Strata Environmental offers a portfolio of environmental consulting services alongside a proprietary software product called EiOS Software. The core offering includes five main service areas: Environmental Due Diligence (Phase I assessments per ASTM standards), Air Quality Services (permitting, modeling, emissions analyses), Compliance Assistance (regulatory support and training), Investigation and Remediation (site investigation and cleanup), and Energy and GHGs (energy audits and alternative energy systems). Complementing these services is the EiOS Software suite—a web-based compliance management platform that tracks, stores, and manages environmental and safety data across one or multiple facilities. Additionally, Strata offers StrataGuides, which are laminated fact sheets covering topics such as Storm Water, Storage Tanks, EPCRA, HazCom, ISO 14001, and ISO 9001. The company functions primarily as a consulting practice rather than a software-only vendor, with EiOS serving as an internal tool to support client compliance tracking.
