Site Waste Management Plan: what it must record

A Site Waste Management Plan is a live document that records what waste a construction project expects to produce, what actually happened, and the paperwork proving where it went. The Site Waste Management Plans Regulations 2008 made it a statutory requirement in England for projects above a cost threshold, and those Regulations were revoked in December 2013. The plan itself did not go away. Local planning authorities require it by condition, assessment schemes such as BREEAM award credits for it, and clients ask for it as part of their own reporting.

The difference now is that nobody prescribes the format, so the quality of the site waste management plan contents varies enormously. A plan amounting to a two-page statement of intent does not satisfy a condition requiring waste to be managed in accordance with an approved plan.

Project details and responsible persons

Start with the identifying information, because a plan that cannot be matched to a site is useless in an audit. Record the site address, the planning application reference and the condition number the plan discharges, the client, the principal contractor, the estimated cost of the project, and the expected start and completion dates.

Then name people rather than roles. The individual responsible for preparing the plan, the individual responsible for updating it during construction, and the individual who will sign off the closing report. Where the principal contractor changes mid-project, record the handover.

That last point sounds administrative. It is the commonest reason a closing report cannot be produced: nobody was maintaining the plan after the second contractor took over.

Forecast waste arisings by stream

The forecast is the analytical part of the document. Break the expected waste down by stream rather than giving a single tonnage, and give both the quantity and the intended destination for each.

State the basis of the forecast. A benchmark rate per m² of floor area, a demolition survey, a cut and fill calculation, or a combination. An unexplained tonnage cannot be reconciled against actuals later, which defeats the purpose of the exercise.

Asbestos deserves its own line and its own paragraph. A refurbishment and demolition survey under the Control of Asbestos Regulations 2012 has to be complete before any strip-out begins, and the plan should reference it by date and reference number.

Applying the waste hierarchy

The duty to apply the waste hierarchy sits in the Waste (England and Wales) Regulations 2011, and it applies whether or not the 2008 Regulations exist. The order is prevention, preparing for reuse, recycling, other recovery, and disposal last.

Applying it properly means showing decisions rather than reciting the order. For each significant stream, say what was considered at each level and why the chosen route was selected. Design-stage prevention measures are the most valuable and the most often omitted: standard component sizes to reduce offcuts, a cut and fill strategy that avoids soil export, retention of existing substructure, and off-site manufacture to shift waste into a controlled factory environment.

An illustrative example: a demolition producing 1,400 tonnes of inert material, crushed on site and reused as piling mat and sub-base, removing around 70 lorry movements from the local road network. Those are illustrative figures, and the point is the reasoning chain: prevention was not possible, reuse was, so recycling off site was not needed.

Reuse and recycling targets and how they are set

Targets come from three places, and a plan should say which applies. A planning condition or a section 106 obligation may set a figure. An assessment scheme such as BREEAM sets its own benchmarks and requires evidence in a particular form. And a client's own sustainability policy may be more demanding than either.

Diversion from landfill for non-hazardous construction and demolition waste is commonly expressed as a percentage by weight, with figures in the region of 90 per cent or above now routine for new-build projects. State the target, state whether it is measured by weight or by volume, and state whether excavated soils are included, because including reused site-won soil makes almost any target achievable and is the standard way of flattering a number.

Carrier, consignment and duty of care records

This is the part that gets audited. The duty of care under section 34 of the Environmental Protection Act 1990 requires waste to be transferred only to an authorised person and accompanied by a written description.

The records to hold, indexed in the plan:

1. Waste carrier registration details for every carrier used, checked against the public register and re-checked on expiry.
2. Environmental permit or exemption details for every receiving site.
3. Waste transfer notes for all non-hazardous movements, with the correct waste description and code.
4. Consignment notes for all hazardous waste movements, with the consignee's returns.
5. Weighbridge tickets or other evidence of quantity, reconciled to the transfer notes.
6. Evidence for material reused on site, which has no transfer note and is therefore the easiest quantity to lose.

Point six is where reconciliations fail. Site-won material reused in place generates no paperwork, so record it contemporaneously with a measured volume and a photograph, or it will be missing from the closing report.

Monitoring, reconciliation and the closing report

The plan is updated as work proceeds, not written once. Practice that works is a monthly reconciliation of forecast against actual by stream, with an explanation for variances beyond a stated tolerance, reviewed at the site progress meeting and recorded in the minutes.

The closing report compares forecast with actual for every stream, states the diversion rate achieved against the target, explains variances, and records lessons for the next project. Under the revoked Regulations this was required within three months of completion, and that remains a sensible discipline and is often written into the condition. Keep the plan and its records for at least two years after completion, longer where hazardous waste consignment notes are involved.

A Site Waste Management Plan covers construction phase waste. Operational waste for the completed building, including bin stores, collection arrangements and storage capacity, belongs in a Waste Management Strategy, and conflating the two is a common drafting error that produces a document satisfying neither condition. Where materials recovered from an existing building are part of the case, the pre-redevelopment audit and circular economy statement work feeds directly into the forecast, and assessment scheme credits are tracked alongside it in the way described for a BREEAM pre-assessment.
