When a chemical spill, oil release, or hazardous substance discharge occurs, federal and state regulations require prompt notification to specific authorities. The reporting landscape spans multiple laws including CERCLA, EPCRA, and the Clean Water Act, each with its own triggers, timelines, and notification recipients. Failing to report can result in significant fines and criminal penalties. This guide covers the major federal requirements and explains how incident management software helps ensure nothing falls through the cracks.
Reporting Challenges
Federal Reporting Framework
CERCLA (Superfund) - Hazardous Substance Releases
The Comprehensive Environmental Response, Compensation, and Liability Act requires immediate notification to the National Response Center (NRC) when a release of a hazardous substance equals or exceeds its reportable quantity (RQ) within a 24-hour period.
- Who reports: The person in charge of the facility or vessel
- When: Immediately upon knowledge of the release
- To whom: National Response Center at 1-800-424-8802
- Threshold: Release must equal or exceed the substance's RQ (ranges from 1 lb to 5,000 lbs)
- Follow-up: Written follow-up report to the EPA Regional Administrator
EPCRA Section 304 - Extremely Hazardous Substances
The Emergency Planning and Community Right-to-Know Act requires additional notifications to state and local emergency authorities when a release of a CERCLA hazardous substance or an extremely hazardous substance (EHS) exceeds its RQ.
- Who reports: Facility owner or operator
- When: Immediately upon knowledge of the release
- To whom: State Emergency Response Commission (SERC) AND Local Emergency Planning Committee (LEPC)
- Threshold: Release equals or exceeds the substance's RQ
- Follow-up: Written follow-up report to SERC and LEPC as soon as practicable
Clean Water Act (CWA) - Oil Discharges
Section 311 of the Clean Water Act requires immediate notification of oil discharges to navigable waters or adjoining shorelines. Unlike CERCLA, there is no minimum quantity threshold for visible oil sheens on water.
- Who reports: Person in charge of the facility or vessel
- When: Immediately upon knowledge of the discharge
- To whom: National Response Center at 1-800-424-8802
- Threshold: Any discharge that violates water quality standards, causes a sheen or film on water, or causes sludge or emulsion on shorelines
Reportable Quantities (RQs)
Common RQs: Sulfuric acid (1,000 lbs), Hydrochloric acid (5,000 lbs), Ammonia (100 lbs), Benzene (10 lbs), Mercury (1 lb), Lead compounds (10 lbs). Many companies maintain RQ lookup tables for their on-site chemicals to enable fast reporting decisions during an event.

State Reporting Requirements
Additional State Obligations
Most states have their own spill reporting requirements that may be more stringent than federal requirements. Common differences include:
- Lower reportable quantities - Some states set RQs below federal thresholds
- Additional substances covered - States may regulate substances not on federal lists
- Shorter notification windows - Some states require notification within 15 minutes to 2 hours
- Additional agencies to notify - State environmental agencies, fire departments, water authorities
- Specific form requirements - Written follow-up reports on state-specific forms
Always check your state's requirements in addition to federal obligations. Your compliance obligations tracking should include both.
Spill Response and Reporting Best Practices
Be Prepared Before a Spill Happens
- Maintain current chemical inventories with RQs for every hazardous substance on site
- Post emergency notification phone numbers (NRC, SERC, LEPC, state agency) in visible locations
- Train employees on spill recognition, response, and reporting procedures
- Pre-identify which chemicals on site have the lowest RQs (most likely to trigger reporting)
- Maintain spill response equipment and ensure it is accessible
- Conduct regular emergency preparedness drills that include reporting practice
