The Emergency Planning and Community Right-to-Know Act (EPCRA) requires facilities that handle hazardous chemicals to plan for emergencies and disclose chemical inventories and releases. While one person or a small group of people are responsible for the official reporting, many engineers in various positions play key roles in identifying new or changing chemicals, changes in storage location, or other changes that might trigger reporting requirements.

This course translates the EPCRA regulatory requirements into practical engineering procedures, providing hands-on tools to help engineers comply with Sections 302–312 (Tier II) and Section 313 (Toxic Release Inventory) reporting. Topics include chemical inventory tracking, mixture threshold calculations, facility notification and planning coordination, and electronic submittals using ePlan and TRI-MEweb.

The course also explores how EPCRA intersects with SPCC, RCRA, and air permitting programs to form a cohesive compliance framework. It will also cover how EPCRA intersects with change management systems and sustainability initiatives.

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

• The purpose and history of EPCRA, including how chemical disasters such as Bhopal led to federal emergency planning and community right-to-know legislation.
• The structure of EPCRA, including Subtitles A, B, and C, and the regulatory sections that define emergency planning, reporting, and general provisions.
• The roles and responsibilities of EPA, SERCs, LEPCs, and local fire departments in chemical emergency planning and public-right-to-know programs.
• When EPCRA Section 302 applies, including Extremely Hazardous Substances (EHS), Threshold Planning Quantities (TPQs), and 60-day notification requirements.
• The requirements of Section 304 emergency release notifications, including Reportable Quantities (RQ), exemptions, and follow-up reporting obligations.
• Tier II reporting obligations under Sections 311–312, including SDS submission, initial vs. annual chemical inventory reporting, thresholds, mixture rules, and state/local variations.
• How to apply mixture and special-case calculations (e.g., solids in solution, molten solids, component concentration thresholds) to determine accurate Tier II reporting quantities.
• How to interpret and apply TRI (Section 313) requirements, including threshold determinations for “manufacture,” “process,” and “otherwise use,” and the criteria for Form R vs. Form A.
• How EPCRA integrates with other environmental programs, such as SPCC, RCRA, OSHA HazCom, and Risk Management Program (RMP), and how overlapping inventories affect compliance.
• Real-world scenarios and case studies that demonstrate how to determine Tier II and TRI applicability, identify common violations, and apply best practices for compliance, documentation, and emergency planning.
