Home / Capabilities / Remediation Action Plans
RAP / scope / validation / closure
Remediation Action Plans that turn investigation findings into a defensible, implementable remediation scope.
iEnvi prepares Remediation Action Plans (RAPs) where regulators, auditors, planning conditions, lenders or internal governance require a documented remediation pathway before works proceed. The work sets out remediation objectives, the selected response, implementation controls, validation criteria, contingency measures and closure logic for contaminated land projects.
Contaminated land remediation scope
Validation and closure planning
Regulator-facing remediation
A RAP is often the document that converts PSI, DSI or risk assessment findings into a scope that can be reviewed, approved, tendered and validated.
The plan reflects the actual contamination setting, exposure pathways, land-use objective and regulator context rather than generic remediation language.
Clear objectives, waste pathways, monitoring requirements and validation criteria help contractors price the work and validators assess closure evidence.
Where a RAP is usually required before remediation can proceed.
Clients typically need a Remediation Action Plan when the site has moved beyond investigation and a formal remediation scope must be agreed with regulators, auditors, councils, counterparties or project governance teams.
EPA notices, audit conditions and approval pathways
Regulators and auditors often require a documented remediation approach with explicit objectives, controls and validation before excavation, treatment or disposal begins.
Planning and redevelopment constraints
Where contamination affects a development programme, the RAP defines how remediation will be staged around construction, waste routes, validation and residual management needs.
Transactions, lenders and portfolio decisions
Counterparties may require a reviewable remediation scope to understand cost, programme, liability and closure risk before committing to a site or asset.
What a defensible Remediation Action Plan should contain.
The RAP has to be usable by the people implementing and validating the works, not just technically correct on paper. iEnvi structures the document around the decisions that actually control remediation success.
Remediation goals tied to land use
Clear remediation objectives linked to the intended land use, risk assessment outcomes, approval conditions or closure requirements for the site.
Excavation, treatment, containment or staged management
Comparison and selection of practical remediation options, including waste classification, beneficial reuse, in-situ treatment, containment or monitored natural attenuation where appropriate.
Controls, monitoring and responsibilities
Site controls, health and safety considerations, environmental monitoring, reporting lines, trigger events and contingency measures during implementation.
Closure criteria and evidence requirements
Validation sampling design, acceptance criteria, sign-off logic and the evidence needed to demonstrate remediation objectives have been met.
RAP preparation following DSI or risk assessment, regulator notice response, service station or industrial site closure, redevelopment staging, and tender support for remediation contractors.
Remediation Action Plan document, validation plan, waste and reuse strategy, monitoring programme, implementation responsibilities and regulator-facing technical support.
This work commonly follows DSI, contamination risk assessment and connects to remediation delivery, waste classification and EMP pathways.
Scope a RAP when remediation needs a reviewable plan, not just informal advice.
If you have investigation findings, regulator pressure or a development programme that depends on a defensible remediation scope, iEnvi can prepare the RAP around the actual closure objective for the site.
