Phase I Environmental Site Assessment in Chester, PA
Chester anchors one of Pennsylvania's most heavily industrialized riverfront markets, sitting on the Delaware River between Philadelphia and Wilmington where I-95, US 13, US 322, and PA 291 converge. Property owners, developers, contractors, municipalities, and counsel working across Delaware County and the Delaware Valley rely on focused, locally informed environmental due diligence. Resource Renewal supports these projects through RCC's ASTM E1527-21 Phase I Environmental Site Assessment scope, layered with PA DEP Act 2 Land Recycling support to deliver both federal and Pennsylvania liability protections.
Resource Renewal connects three service tracks under one platform: ASTM E1527-21 Phase I ESAs and PA DEP Act 2 submissions delivered by RCC; Phase II Site Investigations and Remedial Investigations when Recognized Environmental Conditions are identified; and full remediation and brownfield redevelopment delivered with our affiliated platform DSR. Project teams coordinate with the PA DEP Land Recycling Program under Act 2 and pursue site closure through Final Report approval and relief from liability.

Environmental Context in Chester and Delaware County
Industrial and Commercial Heritage
Chester was incorporated in 1682 and is the oldest city in Pennsylvania, serving as the seat of Delaware County until 1851. Its waterfront became one of the heaviest concentrations of heavy industry on the Delaware River: Sun Shipbuilding and Drydock, the largest single shipyard in the world during World War II, the John Roach yard that later became Ford's Chester Assembly plant, Scott Paper, Congoleum-Nairn, Wetherill Steel, Belmont Iron Works, American Steel Foundries, and Crown Smelting. That layered industrial history drives Phase I ESA recommendations today, with former foundries, plating shops, fuel terminals, rail sidings, gas stations, and dry cleaners distributed through the waterfront district and along the US 13 and PA 291 corridors.
Current Environmental Profile
PA DEP Land Recycling Program and storage tank records show active and closed cleanup sites distributed across Chester and Delaware County. Common contaminants in this corridor include petroleum hydrocarbons (TPH, BTEX) from former service stations, fuel terminals, and underground storage tanks, chlorinated solvents (PCE, TCE) from metal finishing and dry cleaning operations, and heavy metals — lead, arsenic, chromium — plus PCBs associated with shipbuilding, foundry, and electrical equipment work. Historic urban fill, foundry sand, and slag are routine findings on waterfront parcels. Soil vapor intrusion is a standard evaluation during residential and mixed-use conversion of former industrial land, and PFAS investigation is now common scope near plating shops and firefighting training areas.
Real Estate and Development Market
Delaware County sits at the center of the Philadelphia metropolitan area, and Chester has been the focus of sustained public and private reinvestment: Subaru Park, home of the Philadelphia Union, opened on the waterfront in 2010, Harrah's Philadelphia opened its racetrack and casino in 2006 and 2007, and The Wharf at Rivertown converted the 1918 Chester Waterside Station generating plant into office and recreational space. Keystone Opportunity Zone designations continue to draw industrial and logistics interest along PA 291 and the Port of Chester. Each of those conversions moves through Phase I ESA review, with transaction volume extending into Eddystone, Ridley, Trainer, Marcus Hook, Upland, and Brookhaven.
Local Regulators, Authorities, and Stakeholders
The PA DEP Southeast Regional Office at 2 East Main Street in Norristown provides Land Recycling and storage tank oversight for Delaware County. Routine touchpoints during Phase II and remedial action work include the Delaware County Conservation District in Media for erosion and sediment control approvals, Delaware County planning and economic development offices, the City of Chester planning and zoning staff, and DELCORA, the regional wastewater authority headquartered at 100 East Fifth Street in Chester. Sites near Chester Creek, Ridley Creek, or the tidal Delaware River frontage often require coordination on Chapter 105 water obstruction and encroachment permitting and floodplain review alongside the remediation scope.
Why This Local Context Matters for Your Project
Local industrial history, the current contaminant profile, regulator office assignments, and real estate transaction velocity all feed directly into Phase I scoping decisions and downstream remediation planning. Three decades of project work across South Jersey and the Delaware Valley mean RCC crews already know the regional regulators, the typical AOC profiles encountered in this corridor, and the surrounding parcels that recur in historical use research. That institutional familiarity shortens timelines and sharpens the recommendations delivered in each report.

How Resource Renewal Serves Chester, PA
Investigation & Compliance (RCC Track)
The ASTM E1527-21 Phase I ESA scope covers site reconnaissance, historical land use review, regulatory database searches, agency file reviews, and key personnel interviews. RCC layers the federal ASTM scope with Pennsylvania Act 2 documentation so projects carry both federal CERCLA protections and a path to state liability relief under the Land Recycling Program. When Recognized Environmental Conditions or Areas of Concern are identified, RCC moves directly into Phase II Site Investigation and, where warranted, Remedial Investigation — coordinating sampling plans, certified laboratory analysis, and data evaluation against the applicable Statewide Health, Site-Specific, or Background standards. Documentation is built for PA DEP review and Final Report approval.
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 exiting impaired property, the DSR platform provides brownfield acquisition, environmental liability transfer, and full redevelopment, applied across more than 100 brownfield sites in NJ, NY, PA, MA, and OH. The Mount Holly HQ at the Resource Renewal Business Park is itself a representative example of a former brownfield converted into productive operating real estate.
Frequently Asked Questions
-
Yes. Chester is served directly from Resource Renewal's headquarters at 10 Lippincott Lane in Mount Holly, a completed brownfield redevelopment project and the home base for RCC and DSR field crews. Surrounding Delaware County municipalities served from this HQ include Eddystone, Ridley Township, Trainer, Marcus Hook, Upland, Brookhaven, Parkside, Chester Township, Upper Chichester, Nether Providence, and Media.
-
A Phase I Environmental Site Assessment is a documented review of a property's current and historical use, performed under ASTM E1527-21, that identifies Recognized Environmental Conditions and Areas of Concern. Typical triggers include commercial real estate transactions, lender requirements, attorney due diligence, pre-redevelopment review, and refinancing. RCC pairs the ASTM Phase I ESA with Pennsylvania Act 2 documentation to provide federal CERCLA innocent purchaser protection and a path to state liability relief. In Chester and Delaware County, the property types most likely to trigger Phase I work are former shipyard and foundry parcels, fuel terminals and service stations, warehouses, rail-served industrial land, and dry cleaning sites.
-
A typical Phase I ESA runs two to three weeks from authorization to draft delivery, depending on environmental database turnaround, depth of historical research, agency file review timing, and site access. RCC can accelerate timelines for time-sensitive transactions when scope and access permit. Layered Pennsylvania Act 2 documentation is coordinated within the same engagement. Under ASTM E1527-21, a Phase I ESA is valid for 180 days, with extensions of up to one year possible if specific components are refreshed.
-
When Recognized Environmental Conditions are identified, the natural next step is a Phase II Site Investigation: a defined sampling plan, certified laboratory analysis, and data evaluation against PA DEP Act 2 standards. If contamination is confirmed, RCC develops a Remedial Investigation and Cleanup Plan, pursuing Act 2 closure and relief from liability through PA DEP Final Report approval. For owners who prefer to exit the property rather than carry it through closure, DSR brownfield acquisition and environmental liability transfer are available as an alternative path.
-
DSR is Resource Renewal's brownfield redevelopment company, with experience across more than 100 brownfield sites in NJ, NY, PA, MA, and OH. DSR services include site evaluation, environmental liability transfer, and full redevelopment. DSR is a member of the EPA Landfill Methane Outreach Program and the Brownfield Coalition of the Northeast, and applies its Turn Brown to Green™ (TB2G™) model for landfill closure and beneficial reuse. EPA Brownfields Program grants and incentives may apply to qualifying Chester and Delaware County sites.
-
Under the Land Recycling and Environmental Remediation Standards Act of 1995 — Act 2 — the remediator selects a cleanup standard, files a Notice of Intent to Remediate, and submits the plans and reports that PA DEP reviews and approves. Pennsylvania does not use a licensed site professional model, so DEP retains direct review authority. Typical sequencing is Notice of Intent to Remediate, site characterization, a Remedial Investigation or Cleanup Plan where required, remedial action, and a Final Report. DEP approval of the Final Report carries relief from further liability and supports transactions, financing, and redevelopment.
-
Chester's waterfront carries more than a century of shipbuilding, foundry, paper, and petroleum activity, and much of that land is now being converted for stadium, casino, office, port, and logistics use. I-95, US 13, US 322 at the Commodore Barry Bridge, and PA 291 make the corridor attractive for industrial and last-mile distribution reuse, and Keystone Opportunity Zone incentives add to the transaction volume. Each of those deals typically triggers a Phase I ESA from lenders or institutional buyers, with activity extending into Eddystone, Ridley Township, Trainer, Marcus Hook, and Upland.
-
The Resource Renewal Business Park at 10 Lippincott Lane is itself a brownfield redevelopment project that moved through the same investigation, remediation, regulatory closure, and reuse process RCC and DSR deliver for clients. It is a working demonstration that contaminated parcels can move from environmental liability to productive operating real estate when investigation, remediation, regulatory strategy, and redevelopment are executed by an integrated team. Prospective clients are welcome to walk the site as part of project scoping.
