Dirty Closures include which elements?

• A. Temporary layoffs during closure.
• B. Post-closure obligations, monitoring and maintenance, and a minimum of 30 years of financial assurance.
• C. No reporting requirements.
• D. Immediate demolition of facilities within 6 months.

Answer: (B)

Dirty closures mean you’re closing a facility while some waste remains, so long‑term care is required. After closure, the owner or operator must take on post‑closure obligations, keep monitoring and maintaining the site (for example, groundwater checks, maintaining the cap and any containment systems, and ongoing maintenance of the remaining units), and provide financial assurance to cover these activities for a minimum of 30 years. This ensures there are funds and a plan to protect people and the environment long after operations stop. Temporary layoffs during closure aren’t part of the regulatory closure requirements, and immediate demolition within six months would undermine the required post‑closure care. There are also reporting needs to document closure and post‑closure activities, so the key concept is the combination of post‑closure obligations, ongoing monitoring/maintenance, and long-term financial assurance.
