NYC Right to Know Filing: Tier II Hazardous Chemical Inventory for Commercial Facilities

If your facility stores hazardous chemicals above federal threshold quantities, New York City's Community Right-to-Know law requires an annual Tier II report filed with the NYC DEP. Oasis Indoor Environmental helps commercial building managers, engineers, and compliance officers complete this filing accurately — with nearly 20 years of regulatory experience behind every submission.

What Is NYC Right to Know Compliance — and Who Has to File?

The NYC Community Right-to-Know law requires facilities that store hazardous chemicals at or above EPA threshold quantities to submit an annual Facility Inventory Form (Tier II report) to the New York City Department of Environmental Protection. This filing discloses what chemicals are on-site, in what quantities, and where they are stored — information the city uses for emergency planning and public transparency.

 

Most commercial facilities that fall under this requirement aren't chemical plants. They're office buildings with backup generators, hospitals with cleaning and sterilization chemicals, warehouses, labs, and multi-tenant properties with centralized mechanical systems. If your facility has chemicals that meet the threshold, the obligation applies regardless of how routine those chemicals seem to your operations.

 

Filing deadlines and threshold quantities are set at the federal level under EPCRA (the Emergency Planning and Community Right-to-Know Act) and enforced locally by NYC DEP. Penalties for late or incomplete filings can be significant — and the obligation doesn't go away because it was missed in prior years.

How Oasis Handles Your Right to Know Filing

We approach NYC Right to Know compliance the same way we approach every environmental engagement: methodically, with documentation that holds up to scrutiny. Our process is built for commercial facilities that need a defensible record, not just a checkbox.

What the NYC Tier II Filing Process Actually Involves

The Tier II report — formally called the Facility Inventory Form in New York City — requires more than a list of chemicals. A complete, compliant filing includes:

 

  • Identification of all hazardous chemicals stored at or above threshold quantities during the prior calendar year
  • Chemical names, CAS numbers, physical and health hazard classifications
  • Maximum and average daily amounts stored, in the correct units
  • General storage location descriptions and storage conditions
  • Facility contact information and emergency coordinator details
  • Submission to NYC DEP by the annual deadline (typically March 1)

 

The complexity comes from correctly identifying which substances qualify, applying the right threshold quantities for each chemical category, and ensuring the location data is accurate enough to satisfy DEP review. Errors or omissions are the most common reason filings get flagged — and a flagged filing puts your facility in a worse position than a late one.

Chemical Inventory Review

We work with your facilities team to identify every chemical stored on-site that may meet federal reporting thresholds. This includes reviewing Safety Data Sheets, storage logs, and mechanical system records — not just the obvious materials.

Threshold Quantity Analysis

Not every chemical triggers a filing obligation, and the thresholds vary by substance and hazard category. We apply the correct federal and local criteria to determine exactly what must be reported — so you're not over-filing or, more importantly, under-reporting.

Facility Inventory Form Preparation

We compile and prepare the complete Tier II report in the format required by NYC DEP, including all required chemical data, storage location descriptions, and facility contact information. Every field is completed to the standard DEP expects.

Filing and Submission

We submit the completed Facility Inventory Form to NYC DEP on your behalf and provide you with a copy of the filed report and confirmation of submission for your compliance records.

Why Facilities Work with Oasis for DEP Chemical Filing

NYC Right to Know compliance sits at the intersection of federal EPCRA requirements and local DEP enforcement — a regulatory space that generalist environmental consultants often don't know well. Our team has spent nearly two decades navigating NYC's environmental compliance landscape, including HPD violations, Local Law 31 lead obligations, and Local Law 55 allergen inspections. The Right to Know filing is one more layer of that same terrain.

 

What distinguishes our work is the documentation standard we hold ourselves to. Reports and filings that leave our office are written to withstand review — by DEP, by legal counsel, or by any other party with standing to examine them. That standard matters when a compliance question surfaces months or years after a filing was submitted.

 

We also work exclusively on the assessment and documentation side of environmental compliance. We have no remediation business, no product sales, and no financial interest in what your chemical inventory looks like. Our job is to file an accurate report — and that's the only outcome we're working toward.

Frequently Asked Questions About NYC Right to Know Filing

  • What is the difference between a Tier I and Tier II report?

    Tier I reports provide aggregate information about hazardous chemical categories stored at a facility. Tier II reports — the standard required by NYC DEP — provide chemical-specific information, including individual chemical names, quantities, and storage locations. NYC requires the more detailed Tier II filing, which is submitted using the Facility Inventory Form.

  • Who has to file a NYC Right to Know Tier II report?

    Any facility in New York City that stores hazardous chemicals at or above the threshold quantities established under EPCRA must file annually with NYC DEP. Common filers include commercial office buildings with backup fuel storage, healthcare facilities, laboratories, warehouses, and industrial properties. If you're unsure whether your facility meets the threshold, a consultation with our team can clarify your obligation before the filing deadline.

  • What happens if we miss the NYC DEP filing deadline?

    Late filings can result in penalties from NYC DEP, and a pattern of non-compliance can draw additional regulatory scrutiny. If your facility has missed prior years' filings, the best course of action is to bring the record current as quickly as possible — we can assist with catch-up filings and help establish a compliant process going forward.

  • Can Oasis file the Tier II report on our behalf, or do we have to submit it ourselves?

    We prepare the complete Facility Inventory Form and can submit it to NYC DEP on your behalf. You receive a copy of the filed report and submission confirmation for your records. Many of our commercial clients prefer this arrangement because it removes the administrative burden and ensures the filing is handled by someone who knows what DEP is looking for.
