Phase I Environmental Site Assessment in Dayton, OH
Dayton sits within one of southwestern Ohio’s most established industrial and redevelopment markets, positioned in Montgomery County with direct access to Interstate 75, Interstate 70, U.S. Route 35, and the broader Miami Valley market. Property owners, developers, contractors, municipalities, lenders, and counsel working across Montgomery County and surrounding southwestern Ohio communities rely on focused environmental due diligence because Dayton has a long history of manufacturing, automotive and aerospace-related industry, metalworking, warehousing, rail activity, and commercial development. Resource Renewal supports these projects through RCC’s ASTM E1527-21 Phase I Environmental Site Assessment scope, supplemented by Ohio-specific regulatory research and due diligence appropriate to the property and transaction.
Resource Renewal connects three service tracks under one platform: ASTM E1527-21 Phase I ESAs delivered by RCC; Phase II Environmental Site Investigations and additional site characterization when Recognized Environmental Conditions warrant further evaluation; and full remediation and brownfield redevelopment delivered with affiliated platform DSR. For contaminated properties in Dayton, project teams can coordinate with the Ohio Environmental Protection Agency and other applicable regulatory programs, with investigation, remediation, and closure strategies tailored to site-specific conditions and redevelopment objectives.

Environmental Context in Dayton and Montgomery County
Industrial and Commercial Heritage
Dayton’s environmental history is closely tied to the Great Miami River and more than a century of manufacturing, automotive production, machining, metalworking, aerospace innovation, and industrial development. General Motors and its predecessor operations became a major part of Dayton’s industrial economy, including the former GM Harrison Radiator complex east of downtown. That facility produced automotive air-conditioning components, household appliances, and other manufactured products and used solvents, plating materials, and petroleum products during its operating history. After the plant closed in 1995, the property became a major brownfield redevelopment project and was ultimately transformed into the Tech Town technology campus.
Current Environmental Profile
Dayton contains a mix of active and former manufacturing properties, automotive facilities, brownfields, warehouses, commercial corridors, and sites with documented soil, groundwater, or vapor concerns. One of the city’s most significant environmental sites is the Behr Dayton Thermal System VOC Plume Superfund site, where historic vehicle air-conditioning manufacturing, industrial laundry operations, chemical storage, and other industrial uses resulted in groundwater contamination by volatile organic compounds. EPA added the site to the National Priorities List in 2009, and vapor mitigation systems have been installed at more than 250 nearby homes as part of the response.
Real Estate and Development Market
Dayton is a major redevelopment and employment center in southwestern Ohio, with commercial and industrial activity supported by Interstate 75, Interstate 70, U.S. Route 35, downtown Dayton, and the broader Miami Valley transportation network. Brownfield redevelopment continues to play an important role in the city’s economic-development strategy. Tech Town is a prominent example, where the former GM Harrison industrial property was assessed, remediated, and repositioned as a technology-oriented business campus. The City of Dayton specifically identifies the creation of shovel-ready sites through brownfield redevelopment as part of its economic-development program, while EPA funding has supported additional Phase I and Phase II assessment work in areas such as the Wolf Creek Corridor.
Local Regulators, Authorities, and Stakeholders
Environmental projects in Dayton can involve municipal, county, state, and federal entities depending on the property and scope of work. The Ohio Environmental Protection Agency administers state environmental programs and Ohio’s Voluntary Action Program, which provides a framework for investigating and addressing contaminated properties and, where applicable, pursuing a No Further Action letter and Covenant Not to Sue. EPA Region 5 may also be involved at federally regulated properties, Superfund sites, and certain brownfield projects. Local redevelopment efforts can involve the City of Dayton, Montgomery County, the Montgomery County Land Reutilization Corporation, and other economic-development and planning organizations.
Why This Local Context Matters for Your Project
Dayton is not a uniform commercial environmental market. Its mix of former automotive plants, metalworking and machining operations, industrial laundries, chemical-use properties, warehouses, rail-served sites, manufacturing corridors, and brownfields creates materially different environmental risks from parcel to parcel. A Phase I Environmental Site Assessment should therefore consider historic industrial and manufacturing uses, petroleum storage, solvents and degreasers, plating operations, underground storage tanks, Recognized Environmental Conditions, Ohio EPA regulatory history, groundwater impacts, vapor intrusion potential, institutional or land-use restrictions, and nearby contaminated properties. Understanding Dayton’s industrial history early can help determine whether Phase II investigation, additional site characterization, remediation, Ohio EPA Voluntary Action Program involvement, or brownfield redevelopment planning may be appropriate before acquisition, financing, or redevelopment.

How Resource Renewal Serves Dayton, OH
Investigation & Compliance (RCC Track)
The ASTM E1527-21 Phase I ESA scope covers site reconnaissance, historical land-use review, regulatory database searches, agency file review, and key personnel interviews. For Dayton and Montgomery County properties, RCC can pair the federal ASTM scope with Ohio-specific regulatory research and due diligence appropriate to the property, transaction, and potential environmental conditions. When Recognized Environmental Conditions are identified, RCC can proceed into Phase II Environmental Site Investigation and, where warranted, additional site characterization or remedial investigation, coordinating soil, groundwater, and soil vapor sampling, certified laboratory analysis, and data evaluation under applicable Ohio EPA requirements. Where appropriate, project teams can also evaluate whether Ohio’s Voluntary Action Program is a suitable pathway for investigation, remediation, and regulatory closure. Documentation can be structured to support property transactions, financing, Ohio EPA coordination, and closure objectives.
Remediation & Redevelopment (DSR-Affiliated Track)
Remediation capabilities include in-situ chemical oxidation, bioremediation, soil vapor extraction, ex-situ excavation and disposal, groundwater pump-and-treat systems, permeable reactive barriers, sub-slab depressurization, and long-term operations, maintenance, and monitoring (OM&M). For owners, investors, and developers working with environmentally impaired property in Dayton, the DSR platform can support brownfield acquisition, environmental liability transfer, remediation, and redevelopment planning. This can be particularly relevant for former automotive and manufacturing facilities, metalworking properties, warehouses, rail-served industrial sites, commercial properties, and redevelopment sites along Interstate 75, U.S. Route 35, the Wolf Creek corridor, and other established industrial areas in Dayton, where environmental due diligence and redevelopment strategy may need to be coordinated from acquisition through cleanup, regulatory closure, and final reuse.
Frequently Asked Questions
-
Yes. Resource Renewal supports environmental consulting, investigation, remediation, compliance, and redevelopment projects in Dayton and throughout Montgomery County through RCC and affiliated DSR. Ohio project work is supported from Resource Renewal’s headquarters at the Resource Renewal Business Park, 10 Lippincott Lane in Mount Holly, NJ, a completed brownfield redevelopment project that serves as the home base for RCC and DSR operations. RCC has provided environmental consulting and remediation services since 1992.
-
A Phase I Environmental Site Assessment evaluates a property’s current and historical uses, regulatory records, surrounding properties, and observable site conditions under ASTM E1527-21. Its purpose is to identify Recognized Environmental Conditions that may indicate the presence or likely presence of hazardous substances or petroleum products. A Dayton property may need a Phase I ESA during acquisition, refinancing, lender due diligence, redevelopment, or another commercial real estate transaction where environmental risk and potential liability are important considerations.
-
A Phase I ESA is commonly completed within approximately two to three weeks, although timing depends on property complexity, site access, availability of historical records, regulatory-file review, and transaction deadlines. Former automotive, manufacturing, metalworking, warehouse, rail-served, and other historically intensive-use properties in Dayton may require additional research.
-
A Recognized Environmental Condition does not automatically mean contamination is present. It indicates that further investigation may be appropriate. RCC can proceed with a Phase II Environmental Site Investigation using targeted soil, groundwater, and soil vapor sampling, laboratory analysis, and other investigative methods. If contamination is confirmed, additional site characterization, remediation, Ohio EPA coordination, or evaluation under the Voluntary Action Program may be appropriate depending on the property and regulatory circumstances.
-
Yes. Through affiliated DSR, Resource Renewal can support brownfield acquisition, remediation, environmental liability transfer, redevelopment planning, and long-term stewardship of environmentally impaired properties. These services can be particularly relevant to Dayton’s former automotive facilities, manufacturing plants, metalworking properties, warehouses, rail-served industrial sites, and other properties being evaluated for adaptive reuse or redevelopment.
-
Ohio’s Voluntary Action Program provides a pathway for eligible contaminated properties to be investigated and remediated using Ohio EPA standards. Work can involve a Certified Professional, Phase I and Phase II property assessments, risk evaluation, remediation, and preparation of a No Further Action letter when applicable. If Ohio EPA reviews and accepts the submission, the property may qualify for a Covenant Not to Sue. Not every contaminated site proceeds through the VAP, so the appropriate regulatory pathway depends on the property, contamination, and project objectives.
-
Dayton has a long history of automotive production, manufacturing, metalworking, machining, aerospace-related industry, warehousing, rail activity, and commercial development. These historical uses can create materially different environmental risks from parcel to parcel. A Phase I ESA can help buyers, lenders, developers, and counsel identify potential concerns involving petroleum storage, solvents, degreasers, plating operations, hazardous-material handling, historical releases, contaminated soil or groundwater, vapor intrusion, and nearby regulated properties before acquisition, financing, or redevelopment.
-
Resource Renewal’s headquarters at the Resource Renewal Business Park in Mount Holly, NJ is itself a completed brownfield redevelopment project. It demonstrates the integrated approach RCC and DSR apply to environmentally impaired real estate: evaluating site conditions, investigating environmental concerns, implementing remediation, addressing regulatory requirements, and returning property to productive use. That same methodology can support brownfield and adaptive-reuse projects involving former industrial, automotive, manufacturing, warehouse, and commercial properties in Dayton.
