How to Use This Checklist
- Provide the location, the date the inspection is conducted, and who prepared the closure plan. These are the identification details that anchor the rest of the assessment.
- Work through the removal of wastes and waste residues. Confirm that the plan describes how accumulated wastes—including tank bottoms, distillation residues, and material in piping, transfer lines, valves, pumps, and internal equipment—will be removed, documented, containerized, labeled, stored, and sent for compliant treatment or disposal.
- Confirm that the plan assumes the facility's maximum theoretical waste inventory will be managed during closure, and that any off-site facilities and treatment, storage, or disposal units receiving the waste streams have been identified.
- Address dismantling and removal. If the unit, its components, parts, or associated equipment and piping will be removed after waste removal, describe the sequencing, dismantling procedures, tools, safety protocols, characterization, segregation, containerization, and disposition strategy for removed materials.
- Carry out the pre-decontamination inspection. Confirm that the plan describes how the structural integrity of the unit and surrounding areas will be evaluated after waste removal but before decontamination, how cracks, fissures, joint separations, corrosion, and other anomalies will be identified, and how field observations will guide environmental sampling.
- Plan decontamination by material type. Confirm that each material requiring decontamination has its own subsection describing interior and exterior cleaning procedures, cleaning agents, application methods, contact durations, rinse protocols, and waste collection systems, along with verification sampling and acceptance criteria.
- Address the decontamination of tools, equipment, scaffolding, and protective apparatus used during the work, so that cross-contamination between areas is prevented. Also confirm that decontamination residuals such as wash water, rinse solutions, concrete dust, abrasive media, spent cleaning agents, and contaminated personal protective equipment are characterized and managed.
- Identify contaminated environmental media, such as surface soil, subsurface soil, groundwater, surface water, and sediments, and document the technical rationale and sampling and analysis program for characterizing each one. Where subsurface sampling at depth is planned, confirm that geological conditions will be characterized in accordance with the Unified Soil Classification System (USCS).
- Confirm the closure. For each material type subject to clean closure confirmation, restate the applicable closure standard and describe the verification procedures—sample collection methods, analytical parameters, spatial coverage, and statistical evaluation approaches. Where relevant, confirm compliance with the Alternative Treatment Standards for Hazardous Debris, and verify that contaminated soil has achieved unrestricted land use cleanup levels.
- Document everything. Confirm that the plan describes the recordkeeping system that will be maintained, including inspection logs, field sampling records, chain-of-custody documentation, laboratory analytical reports, photographic documentation, professional engineer certifications, and final closure reports.
- Record the outcome. Note whether an independent qualified registered professional engineer supervises decontamination activities and provides final certification. Use the Yes, No, and N/A options to indicate whether each requirement has been addressed in the plan, and complete the signature and inspection dates when the assessment is finished.

What a clean closure plan covers
A clean closure plan is the documented set of procedures for removing hazardous materials from a facility and returning the site to a condition that regulators can verify. When a facility that manages hazardous materials stops operating, waste residues do not disappear on their own. They collect in tank bottoms, distillation units, piping, transfer lines, valves, pumps, and internal processing equipment. Components and parts that have contacted dangerous waste remain hazardous unless they are properly decontaminated. Soil, groundwater, surface water, and sediments near the site may carry contamination that only becomes apparent once wastes are removed. The plan ties all of this together. It describes how wastes will be removed, how components will be dismantled and dispositioned, how surfaces will be decontaminated, how affected environmental media will be characterized, and how you will demonstrate that clean closure has been achieved. This template follows the structure of established regulatory closure plan guidelines and covers seven areas: closure activities, removal of wastes and waste residues, unit components and ancillary equipment, pre-decontamination inspection, decontamination, contaminated environmental media, and confirmation of clean closure. It should be customized to align with your local and state requirements.
Removal of wastes and waste residues
Removal of all wastes and waste residues is a mandatory requirement of clean closure, and the plan needs to say exactly how it will be done. That means a thorough description of the procedures and methodologies for removing accumulated wastes from the unit undergoing closure, with attention to the less obvious places waste accumulates: piping systems, transfer lines, valves, pumps, and internal processing equipment associated with recycling or used oil processing operations. The plan should document the specific procedures, specialized equipment, and operational methodologies for achieving maximum practicable removal, including techniques for accessing difficult-to-reach areas. It should also outline how removed wastes and residues will be managed through containerization, hazardous waste labeling, container storage, and compliant treatment and disposal at permitted facilities. Where off-site management is planned, the plan identifies the categories of dangerous waste management facilities and treatment, storage, or disposal units that will receive the waste streams. One point deserves particular care: the closure plan should be developed on the assumption that the facility's maximum theoretical waste inventory—the greatest volume of waste that could be present at full operational capacity—must be managed during closure, rather than relying on projected or typical volumes expected at the time of closure.
Dismantling units, components, and equipment
If the facility elects to dismantle and remove the unit, its components, parts, or associated equipment and piping after waste removal, the plan needs a comprehensive description of that removal strategy, including work sequencing, safety protocols, and required equipment. Dismantling procedures themselves should be specified, along with the specialized tools, heavy equipment, protective measures, and safety protocols used during physical removal of unit structures, internal components, and associated parts. Unit components and parts that have contacted dangerous waste must be managed as dangerous waste unless properly decontaminated. The plan should therefore describe the characterization, segregation, containerization, and disposition strategy for all removed components and materials. It should also identify all applicable federal, state, and local waste management regulatory requirements for removed waste, unit parts, components, and ancillary materials, and describe how compliance with each requirement will be achieved and demonstrated. Where off-site treatment or disposal is required, identify the specific types of dangerous waste management units, facilities, and treatment technologies involved.
Inspection before decontamination
Pre-decontamination inspection is a mandatory element of clean closure. Once wastes have been removed but before any decontamination begins, the plan should describe a systematic inspection protocol for evaluating the structural integrity and condition of the unit and surrounding areas. The detailed inspection methodology matters here. You are looking for cracks, fissures, joint separations, corrosion damage, and other structural anomalies in containment systems that could indicate potential waste migration pathways or historical release points. The plan should establish procedures for documenting all field observations that may indicate potential or historical releases from containment structures, and describe how those findings will inform and guide subsequent environmental sampling strategies for soil, groundwater, and other potentially affected media.
Decontamination
Decontamination starts with an inventory. The plan should identify and catalogue all material types requiring decontamination—carbon steel tank walls, stainless steel components, concrete containment structures, epoxy coatings, piping interiors—and create dedicated subsections detailing material-specific procedures for each. For each material type, the plan provides comprehensive descriptions of decontamination procedures for both interior and exterior surfaces, including specific cleaning agents, application methodologies, contact durations, equipment specifications, rinse protocols, and waste collection systems. It should also describe the verification methodology and acceptance criteria used to confirm that decontaminated materials meet the applicable clean closure decontamination standards, including sampling protocols, analytical test methods, and numerical pass/fail thresholds. Where a site-specific decontamination standard is proposed instead of an established regulatory standard, the plan should provide a thorough technical justification: the proposed numerical standards, the scientific or risk-based rationale supporting those values, and the supporting documentation and references. Contingency procedures and adaptive management strategies should cover scenarios where initial decontamination efforts fail to achieve required standards, including alternative cleaning methods, repeated treatment protocols, equipment modifications, and escalation procedures. Two practical points are easy to overlook. First, tools, equipment, scaffolding, protective apparatus, and other items used during decontamination itself must be decontaminated so that cross-contamination between areas is prevented and equipment is properly cleaned before it leaves the work area. Second, all decontamination residuals—wash water, rinse solutions, concrete dust, abrasive media, spent cleaning agents, contaminated personal protective equipment—need management procedures covering waste characterization, applicable regulatory requirements, and compliance strategies for each residual type. Throughout the process, the plan should describe the role, oversight responsibilities, verification activities, and certification procedures of the independent qualified registered professional engineer who will supervise decontamination, including inspection milestones, documentation reviews, and final certification requirements.
Contaminated environmental media
The plan should identify all environmental media that are known to be contaminated or reasonably suspected of contamination based on operational history, documented spills, equipment failure records, or previous environmental investigations. That includes surface soil, subsurface soil, groundwater, surface water, and sediments. For each identified medium, the plan provides a detailed technical rationale explaining the basis for suspecting contamination, along with a comprehensive sampling and analysis program. Sample locations, depths, analytical parameters, quality assurance protocols, and data quality objectives should all be described, with the goal of fully characterizing the nature, vertical extent, horizontal extent, and severity of contamination. Where subsurface soil sampling at depth is planned, the plan should confirm that subsurface geological conditions will be characterized and documented in accordance with the Unified Soil Classification System (USCS), so that regulatory reviewers can properly evaluate sampling strategies, interpret analytical results, and assess the potential for contaminant migration to groundwater.
Confirming clean closure
Confirmation is where the plan demonstrates, with evidence, that closure standards have been met. For each material type subject to clean closure confirmation—decontaminated concrete containment systems, steel tank components, subsurface soils, piping networks—the plan should enumerate the material, restate the applicable closure standard, and describe the verification procedures that will be employed: sample collection methods, analytical parameters, spatial coverage, and statistical evaluation approaches. The plan should also describe the verification protocols used to confirm compliance with the Alternative Treatment Standards for Hazardous Debris, or any approved site-specific debris decontamination standard, across all decontaminated areas, including sampling density requirements, analytical test methods, data quality objectives, and documentation procedures. For contaminated soil, describe the sampling, analysis, and verification methodology that will confirm remediation to unrestricted land use cleanup levels under applicable environmental remediation standards, including specific cleanup criteria, verification sampling protocols, and statistical methods for demonstrating compliance. None of this holds together without records. The plan should describe the comprehensive documentation and recordkeeping system that will be maintained—inspection logs, field sampling records, chain-of-custody documentation, laboratory analytical reports, photographic documentation, professional engineer certifications, and final closure reports—so that regulatory authorities can independently verify that all clean closure standards have been achieved.
Using the checklist
The checklist contains 36 items across its seven sections. On site or at your desk, work through the questions in order, answering Yes, No, or N/A for each. A Yes indicates that the item is addressed in the closure plan you are reviewing or developing; a No flags a gap that needs to be closed before the plan is submitted; N/A indicates that the provision does not apply to your facility. The checklist begins with administrative items—date conducted, preparer, location—and closes with a signature and completion fields, including the actual start and end dates of the inspection. Because the template is built from established regulatory closure plan guidelines, review it against your local and state regulatory requirements before use and adapt the items to match the specific conditions of the facility being closed.
