Understanding State-by-State Differences in EPCRA Tier II Reporting

As we approach the annual March 1 Tier II reporting deadline, it is worth revisiting how some states implement Section 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA) differently.  Although Tier II reporting is federally mandated, the states administer the program, resulting in variations in thresholds, submittal systems, and documentation requirements.  For companies operating in multiple jurisdictions, these differences can significantly affect compliance obligations.

Below is a short overview of several state differences to be aware of when evaluating your facilities’ reporting needs for the 2025 reporting year.

Federal Baseline Requirements

Federal rules establish the minimum standards for all facilities:

• Hazardous Chemicals:  Any substance requiring a Safety Data Sheet under OSHA.
• Hazardous Chemical Threshold:  Reporting is generally triggered at 10,000 pounds.
• Extremely Hazardous Substances (EHS):  Reportable at 500 pounds or the Threshold Planning Quantity (TPQ), whichever is lower.
• Retail Fuel Stations: Higher thresholds apply when tanks meet federal UST requirements—75,000 gallons of gasoline and 100,000 gallons of diesel.

States may adopt stricter thresholds and additional reporting elements, and many do.

States with Lower or More Stringent Reporting Thresholds

Several states require reporting well below the federal 10,000-pound level:

• California:
  • 500 pounds for solids
  • 55 gallons for liquids
  • 200 cubic feet for compressed gases

Report deadlines can vary depending on the local CUPA. Submissions are part of the broader Hazardous Materials Business Plan (HMBP) under CERS.

• Louisiana:
  • 500 pounds for any hazardous material unless the TPQ is lower.

Requires attention to both state and parish-level expectations.

• Vermont:
  • 100 pounds or the TPQ, whichever is lower.
  • 10,000 pounds for petroleum products and fuels
  • Any amount of carcinogens or explosives

One of the strictest reporting thresholds nationwide.

• New Jersey:
  • Facilities are subject to the New Jersey Environmental Hazardous Substance (EHS) list. This list contains thresholds that are lower than federal thresholds.
    • 500 pounds if RQ is not listed
  • 10,000 pounds if chemical is not listed.

Retail fuel station exemptions may vary by state; some require additional documentation or verification of UST compliance before higher thresholds apply.

Differences in Submission Systems and Reporting Platforms

Submission expectations can differ:

• Texas:
  All facilities must submit using the STEERS Tier II Reporting system.
• New York:
  State agencies accept Tier II reports via E-Plan.
  New York City, however, administers its own program with lower thresholds and requires a separate Facility Inventory Form (FIF).
• South Carolina:
  Requires exclusive use of E-Plan for state submissions.
• Colorado:
  Requires use of Tier2 Submit. The state distributes reports to LEPCs and fire departments that maintain the same reporting requirements. Some LEPCs and fire departments may require additional reporting elements.
• Florida:
  Accepts Tier II reports through E-Plan and imposes additional requirements related to facility emergency contacts and notifications.

Additional Documentation and State-Specific Requirements

Several states require more extensive submissions than the federal minimum:

• California – HMBP:
  Requires detailed emergency response plans, training elements, and annotated site maps in addition to standard chemical inventory information.
• Oregon:
  Requires a detailed site diagram.
• Washington:
  Requires Tier II reporting to both the State Emergency Response Commission (SERC) and local fire authorities, with specific formatting expectations for site maps.
• Connecticut:
  Requires Tier II reports to be submitted directly to local fire departments, often with unique local formatting and mapping requirements.
• Illinois:
  Uses the state-managed SERC portal with specific formatting expectations for site maps.
• Nevada (Clark County):
  • Tier II reporting differs from most states because it relies on International Fire Code (IFC) thresholds rather than the federal 10,000-pound standard, often triggering reporting at much lower quantities for common chemicals.  The Nevada submission functions not only as an EPCRA report but also as a State Fire Marshal operating permit, with a dual reporting period and heightened accuracy expectations.
  • Imposes additional recordkeeping requirements and local hazardous materials fees.

These differences underscore why relying solely on federal guidance can leave facilities exposed to noncompliance at the state and local levels.

Supporting Multi-State Operations

Because each state has the ability to dictate its own:

• reporting thresholds,
• required supplemental documents,
• electronic submission platform, and
• local distribution requirements,

companies operating across several jurisdictions should reassess reporting applicability annually; not just at the federal level, but for each state and local authority.
