Closing a business or moving it to another site does not end its environmental obligations. The Implementing Regulation for Environmental Permits applies to the activity at every stage, including closure, and allows the National Center for Environmental Compliance (NCEC) to include closure controls in the operating permit conditions. The site you leave remains your responsibility if it is left with materials, waste or contamination. This article is a practical checklist of environmental obligations before you leave.

The legal basis for closure

  • Scope: the Permits Regulation applies to owners and operators of any activity with an environmental impact, covering construction, operation, modification, addition, expansion and closure.
  • Closure controls: NCEC may include closure controls and conditions in the operating permit conditions, so check your permit first.
  • Liability for impacts: the permit holder is responsible for any environmental impact and its treatment if it appears during the activity's stages.
  • Pollution at closure: the Rehabilitation Regulation requires a contaminated site remediation plan after any pollution incident during construction, operation or closure, and anyone who caused pollution or degradation must stop its source, remove it and rehabilitate the site.

Environmental closure checklist, step by step

  1. Check the closure controls in the operating permit and NCEC's current procedures.
  2. Inventory remaining materials: raw and chemical materials, fuel, oils and refrigerants.
  3. Deal with the materials: return them to suppliers, move them to the new site, or hand unused ones as waste to a carrier licensed by the National Center for Waste Management (MWAN).
  4. Empty and clean tanks: fuel and chemical tanks, oil separators and grease traps, handing sediment to a licensed carrier.
  5. Accumulated waste: hand it all over with transport documents; the Waste Management Law prohibits leaving waste outside designated places.
  6. Refrigeration and air conditioning units: refrigerants are covered by the Ozone-Depleting Substances Regulation, which prohibits disposing of controlled substances and equipment without NCEC approval.
  7. Site assessment: evaluate soil condition at storage, unloading and underground tank areas.
  8. Rehabilitation or remediation plan: if contamination or degradation is found, prepared by a licensed provider and submitted to NCEC for approval before implementation.
  9. Keep the documents: all transport, handover, assessment and remediation records prove you left the site clean.

Activities where closure is more sensitive

  • Fuel stations: underground tanks and lines, and leaks that went undetected during operation.
  • Workshops: years of oil and grease in floors and drainage pits.
  • Chemical warehouses: residual materials and contaminated containers.
  • Quarries and crushers: changed landforms and vegetation, requiring a closure and rehabilitation plan.
  • Factories: contaminated lines and equipment, and hazardous waste storage areas.

When relocating the activity

The activity at the new site needs a new permit starting with the classification form, because site, land use and surrounding sensitive receptors are classification criteria in the regulation. The old permit does not move with the equipment. If the new site is within, or 500 meters or less from, sensitive areas or receptors, it needs a detailed EIA. The old site remains your responsibility until it is properly closed.

Who pays if contamination appears after you leave?

Under the polluter-pays principle in the Rehabilitation Regulation, the polluter bears the costs of studies, corrective measures, rehabilitation and compensation. Assessing the site before handover and documenting its condition protects you from later claims, and protects the next owner or tenant from bearing what they did not cause.

Frequently Asked Questions about Environmental Closure

Do I need to inform NCEC when closing?

Check the closure controls in your operating permit and NCEC's current procedures; NCEC may include closure conditions in the operating permit.

What do I do with leftover chemicals?

Return them to the supplier if possible, move them to the new site, or hand them to an MWAN-licensed carrier; never leave them on site.

Does every closure need a rehabilitation plan?

Not always. It is required if there is contamination or degradation, if the permit's closure controls require it, or for activities that change the land such as quarries.

Does the environmental permit move to the new site?

No. The site is a classification criterion, so the activity at the new site starts a new file with a new classification form.
