If NYC OER issues a Voluntary Cleanup Program Notice of Completion for your project, the regulatory work may be finished. The grant work may not be.
For the NYC Brownfield Incentive Grant, the six months after the Notice of Completion create a critical application window for eligible enrollment grant costs. OER states that BIG enrollment grant applications must be submitted no later than six months after the agency issues the project’s Notice of Completion. The application must include the required documentation, including invoices and manifests when applicable.
That is a project deadline tied to your site. It is not a universal 2026 calendar deadline. It also does not guarantee an award. Funding remains subject to program rules, available appropriations, application completeness, and OER review.
This guide explains how developers in Brooklyn, Queens, the Bronx, Manhattan, and Staten Island should plan for the NYC OER Brownfield Incentive Grant before closeout.
The six-month BIG grant window starts with the Notice of Completion
The most important date is the date OER issues the project’s Notice of Completion.
The official NYC OER BIG Grants page states:
“BIG enrollment grant applications must be submitted no later than 6 months after OER issues the project’s Notice of Completion.”
The NYC BIG program rule provides additional detail. For qualifying projects, the complete application must be submitted with invoices and applicable manifests within six months of receiving a Notice of Completion or Notice of Satisfaction from OER, or a Certificate of Completion from NYSDEC where the applicable rule allows it.
Do not wait for the final month.
A developer should build the grant file before the cleanup reaches final sign-off. Waiting until the Notice of Completion arrives can create avoidable problems:
- Invoices may not identify the eligible activity clearly.
- Soil disposal manifests may be incomplete.
- Vendor registration may not be confirmed.
- Approved work plans may not match the costs being claimed.
- Ownership or development information may have changed.
- Project records may sit with multiple contractors and consultants.
A Notice of Completion closes one regulatory phase. It starts a grant documentation sprint.
BIG eligibility is not the same as regulatory closeout
This distinction matters.
Regulatory closeout asks whether the approved remedy was completed and whether OER has enough documentation to issue a Notice of Completion.
BIG grant eligibility asks whether the applicant, property, costs, vendors, timing, insurance, and documentation meet the requirements for reimbursement.
A site can receive a Notice of Completion and still have a grant application reduced, delayed, or rejected if the submission does not satisfy BIG requirements.
The grant does not replace:
- An OER-approved remedial action work plan
- Required field oversight
- Confirmation sampling
- Remedial action reporting
- Site management planning
- Institutional or engineering controls
- Required insurance
- Regulatory response to OER comments
The grant also does not guarantee that every project cost qualifies. Envicon helps developers keep these two tracks coordinated. Our NYC brownfield remediation team works from the approved remedy, the project budget, and the documentation requirements at the same time.
What the NYC OER Brownfield Incentive Grant can support
The BIG program provides different grant categories. The appropriate category depends on the property, project status, development plan, and regulatory pathway.
Pre-development and due diligence
Pre-development activities can include items such as:
- Title search and title insurance
- Market analysis and feasibility work
- Concept plans and zoning analysis
- Pro forma financial analysis
- Site surveys
- Community outreach
- Phase I Environmental Site Assessments
The NYC Business Pre-Development Design Grant guidance identifies a maximum of $5,000 for qualifying projects and up to $10,000 for certain Preferred Community Development Projects. The applicable grant cap and eligible reimbursement depend on the current program rules.
Environmental investigation
Environmental investigation funding may support work used to characterize site conditions, including:
- Phase II site characterization
- Soil, groundwater, and soil vapor sampling
- Laboratory analysis
- Remedial investigation work plans
- Phase II and remedial investigation reports
This is where a clean scope and defensible sampling plan matter. A generic investigation can produce data without creating a usable path to cleanup or redevelopment.
Approved cleanup work
For projects enrolled in the NYC Voluntary Cleanup Program, cleanup grants may support eligible work performed under an OER-approved remedial action work plan. Potential activities can include:
- Soil excavation and disposal
- Tank removal
- Backfill and clean fill placement
- Caps and cover systems
- Vapor barriers
- Sub-slab depressurization systems
- Groundwater remediation
- Confirmation sampling
- Site management plans
- Remedial action reports
- Field oversight and documentation
The BIG program rule’s eligible activity provisions control. Do not assume that a cost qualifies simply because it appears on a construction invoice.
Environmental insurance
BIG documentation may include eligible environmental insurance expenses, such as pollution legal liability or cleanup cost cap insurance, when the coverage and project circumstances meet program requirements.
Review the OER insurance fact sheet before purchasing coverage. Insurance should be planned early. It should not be treated as a last-minute attachment to a reimbursement package.
Technical assistance and community uses
The program can also support certain technical assistance and community-focused activities. These may relate to:
- Affordable housing
- Community facility development
- Brownfield Opportunity Area planning
- Community brownfield planning organizations
- Development of technical and legal documents
- Project sequencing and scheduling
- Budgets and reuse plans
- BIG or BOA application preparation
Affordable housing and community projects may qualify as Preferred Community Development Projects, but the designation requires documentation. A project’s community benefit should be supported by the development plan, affordability information, letters of interest, or other materials requested by OER.
Funding availability is a planning issue, not a promise
The current OER BIG page lists grant categories and maximum amounts. For example, the page identifies maximum amounts for qualifying brownfield projects, Preferred Community Development Projects, and certain bonus grants.
Those figures should not be treated as an automatic project award.
The BIG rule states that awards are made within the fiscal year until funds are exhausted. The rule also addresses available appropriations and first-come, first-served distribution. That means developers should confirm current funding status with the BIG Program Administrator before committing to a reimbursement assumption in the project budget.
Contact the program administrator through the information on the official OER BIG page. Envicon can help organize the technical file, but OER determines program eligibility and award decisions.
Clean Soil Bank planning belongs in the project budget
The NYC Clean Soil Bank may help eligible projects identify or manage clean soil resources. For a brownfield developer, the value is practical. Clean fill decisions affect excavation sequencing, import costs, trucking, documentation, and the final site management strategy.
Do not assume Clean Soil Bank material will be available for your project or that it will automatically qualify as a BIG reimbursement. Confirm current requirements, material suitability, timing, and documentation with OER and the project team.
Your cleanup plan should answer:
- What soil volume will the site need?
- What material specifications apply?
- When will clean fill arrive?
- Who will document source, delivery, and placement?
- Does the approved remedial action work plan address the material?
- How will clean fill records connect to the final remedial action report?
Envicon coordinates soil management, waste characterization, disposal documentation, and field oversight so that the funding file reflects what happened in the field.

BIG application support for Brooklyn, Queens, and every NYC borough
The same basic discipline applies whether your project is a Brooklyn industrial conversion, a Queens mixed-use redevelopment, a Bronx community facility, a Manhattan property with an E-Designation, or a Staten Island waterfront site.
Envicon’s NYC environmental consulting team works across:
We coordinate the regulatory file, field records, cost documentation, and development schedule. That is the difference between handing over a report and preparing a file that can move.
Frequently asked questions
Does a Notice of Completion guarantee BIG funding?
No. The Notice of Completion starts the six-month application window for applicable enrollment grants. OER still reviews eligibility, costs, documentation, funding availability, and compliance with program requirements.
What is the BIG grant application deadline after Notice of Completion?
For applicable enrollment grants, the application must be submitted no later than six months after OER issues the project’s Notice of Completion. The deadline is project-specific. It is not a single fixed 2026 date for every developer.
Can a project apply for BIG funding before regulatory closeout?
Some pre-enrollment and environmental investigation grants apply before VCP enrollment or before cleanup. The correct grant category depends on the property and project status. Review the current OER BIG requirements before incurring costs.
Are affordable housing projects eligible for higher amounts?
Certain affordable housing and community-supported projects may qualify as Preferred Community Development Projects and may have higher grant limits. OER requires supporting documentation. Eligibility is not automatic.
Do invoices and manifests need to be submitted?
The BIG rule requires a complete application with invoices and manifests when applicable for relevant projects. Maintain these records throughout cleanup instead of trying to reconstruct them after closeout.
Can BIG funding pay for Clean Soil Bank material?
Do not assume it can. Clean Soil Bank participation and BIG reimbursement are separate questions. Confirm material eligibility, project fit, documentation, and current program guidance with OER.
