CORE Environmental Consultants provides full-service support to guide sites through the final stages of environmental remediation—ensuring that all regulatory requirements are satisfied, documentation is complete, and official closure is achieved. Our Regulatory Closure & Coordination services span communication with NYSDEC and other agencies, preparation of closure documents, and coordination of long-term compliance obligations like Environmental Easements and Institutional Controls.
From Brownfield Cleanup Program (BCP) projects to State Superfund and voluntary cleanups, CORE ensures your site exits remediation with confidence and in full compliance.
Regulatory closure refers to the formal conclusion of environmental remediation at a site, typically involving:
CORE manages every step of this process—minimizing risk and expediting approvals.
We help clients achieve closure by:
✔ Proven Track Record
We’ve closed dozens of BCP, Superfund, and voluntary cleanup sites across New York State, working closely with NYSDEC and OER.
✔ FERs That Withstand Review
Our engineering documentation is thorough, well-organized, and backed by field data—ensuring smooth reviews and minimal resubmittals.
✔ Start-to-Finish Support
From final remediation verification through certificate issuance, CORE stays hands-on throughout the entire closure process.
✔ Alignment with Redevelopment Goals
We ensure closure doesn’t just check regulatory boxes—but clears the path for safe occupancy, financing, and reuse.
CORE conducts Remedial Investigations (RIs) and Feasibility Studies (FSs) in accordance with NYSDEC DER-10 to characterize contamination and evaluate cleanup alternatives. Our services include sampling plans, conceptual site models, risk assessments, and cost-benefit analyses to support the selection of effective, regulatory-approved remedial strategies.
CORE offers comprehensive support for Brownfield Cleanup Program (BCP) sites, guiding property owners and developers through investigation, remedial action planning, community outreach, and documentation. We coordinate closely with NYSDEC to secure Certificates of Completion (COCs), tax credit eligibility, and regulatory closure for redevelopment projects on environmentally impacted land.
CORE designs and implements both in-situ and ex-situ remediation technologies to treat contaminated soil, groundwater, and vapor at active and legacy sites. Our capabilities include excavation, chemical oxidation, bioremediation, soil vapor extraction (SVE), and stabilization techniques, selected based on cost, site access, contaminant type, and regulatory targets.
CORE designs vapor intrusion mitigation systems that protect indoor air quality in buildings located above contaminated subsurface environments. Our services include sub-slab depressurization system (SSDS) design, passive venting, vapor barriers, and post-installation verification sampling, all compliant with NYSDOH and NYSDEC guidance.
CORE conducts routine and long-term groundwater monitoring programs to track contaminant migration, demonstrate remedy effectiveness, and support regulatory closure. We install and sample monitoring wells, analyze results against groundwater standards, and prepare detailed reports for submission under DER-10, BCP, and Superfund oversight.
CORE prepares and maintains Site Management Plans (SMPs) and Periodic Review Reports (PRRs) to ensure the long-term protectiveness of institutional and engineering controls. Our reports include inspection protocols, maintenance records, and regulatory certifications that align with NYSDEC DER-10 and site-specific environmental easements.
CORE manages the regulatory closure process by compiling investigation and remediation data, preparing closure reports, and coordinating with NYSDEC, NYC OER, and other agencies. Our goal is to achieve No Further Action (NFA) determinations or Certificates of Completion (COCs), ensuring sites are compliant, documented, and redevelopment-ready.
Let CORE handle the coordination, documentation, and communication necessary to secure formal closure and regulatory approval.
