Introduction
If you've searched for "Schedule 13A of the Environmental Permitting Regulations," here's the first thing worth knowing: the official legislation actually labels this provision Schedule 13, not 13A. It sits inside the Environmental Permitting (England and Wales) Regulations 2016 and deals specifically with waste incineration and co-incineration plants, not with businesses generally.
Many readers struggle to work out whether their facility is even covered, let alone what conditions follow once it is. Others want to understand monitoring duties, emissions limits, and what happens if something goes wrong.
This article breaks down the UK legal framework and what the schedule actually requires, then looks at how enforcement plays out in practice. For Australian readers comparing regulatory systems, it also explains why this UK schedule does not transfer automatically to a facility operating in Australia.
Key Takeaways
- Schedule 13A must be read with the Environmental Permitting Regulations 2016, your site permit, and regulator guidance.
- Controls waste-incineration pollution risk through operating standards, emissions limits, monitoring, and records.
- Coverage depends on plant purpose, waste type, capacity, and new-versus-existing status.
- This UK schedule does not apply in Australia; state and territory regulators set the relevant rules.
Understanding the Legal Framework Behind Schedule 13
The Correct Citation and Its Structure
The instrument's full title is The Environmental Permitting (England and Wales) Regulations 2016 (SI 2016/1154). Within it, Schedule 13 is headed "Waste incineration: Industrial Emissions Directive", covering specified plants in England and Wales only.
The schedule has three operative parts worth knowing:
- Paragraph 1 sets out which plants fall within its reach.
- Paragraph 3 requires specified information in permit applications.
- Paragraph 4 directs regulators on exercising their functions by reference to listed industrial emissions provisions.
What Changed After Brexit
The schedule isn't static. The Environmental Permitting (England and Wales) (Amendment) (EU Exit) Regulations 2019 (SI 2019/39) removed paragraph 2 and amended paragraph 4, with those changes taking effect from 31 December 2020.
Best available techniques (BAT) conclusions for waste incineration were published in December 2019, before the UK's 1 January 2020 cut-off for continuing BAT documents. These conclusions remain a live domestic permitting reference in England and Wales. They haven't been generally superseded for this sector, even though EU law no longer applies directly.
How the Pieces Fit Together
Three layers work together for any covered plant:
- Schedule 13 sets the baseline legal reach.
- Applicable BAT conclusions translate technical expectations around monitoring, emissions, and residues.
- The individual environmental permit turns those principles into site-specific, enforceable conditions.
This is an educational overview. Always check the current legislation, your actual permit, and regulator correspondence, or get specialist advice, before relying on any of this for a compliance decision.
Who and What Schedule 13 Applies To
Defining the Regulated Activity
Regulation 2 defines a waste incineration plant as one dedicated to thermal treatment of waste, with or without heat recovery. A co-incineration plant has a different primary purpose (generating energy or producing materials) but uses waste as a regular or additional fuel.
Both definitions can extend to pyrolysis, gasification, or plasma treatment where the resulting substances are later incinerated. The test is about process and purpose, not what the project is branded as.
Capacity Thresholds That Matter
A small waste incineration plant is defined by capacity:
- No more than 10 tonnes per day for hazardous waste, or
- No more than 3 tonnes per hour for non-hazardous waste
Schedule 13 covers small plants as well as larger incineration and co-incineration operations, but excludes plants operated purely as a domestic activity connected with a private dwelling. The 2019 BAT conclusions use the same thresholds to define their own scope, with additional qualifications, so a small-plant classification alone doesn't settle every permit question.
New vs. Existing Plants
Rather than one general definition, the 2019 BAT conclusions define a new plant as one first permitted after their publication, or a complete replacement built after that date. An existing plant is simply any plant that isn't new. Transitional timing can change which obligations apply, so this needs checking against the current documents rather than assumed.
Where Scope Gets Complicated
Facilities can drift in or out of clear scope when:
- Plant design or combustion technology changes
- Fuel or waste feedstock shifts
- Throughput or operating hours increase
- Modifications affect emissions behaviour
Any of these can trigger a permit variation or a regulator notification requirement. Flag them early rather than discovering them at an inspection.
What Schedule 13 Requires from Waste Incineration Operators
The Core Operating Principle
Waste must be managed and combusted under controlled conditions designed to prevent or minimise harmful effects on air, water, soil, human health, and the wider environment. Everything else in the schedule and BAT conclusions builds on this.
Combustion, Emissions, and Monitoring
Operating controls typically cover feedstock handling, start-up and shutdown procedures, and preventing avoidable incomplete combustion. On the emissions side, the 2019 BAT conclusions identify continuous monitoring for pollutants including carbon monoxide, nitrogen oxides, sulphur dioxide, and hydrogen chloride, with other pollutants subject to periodic or conditional monitoring.
There's no single universal emission number for every incinerator: the relevant pollutant, the specific BAT provision, and the actual issued permit all determine the applicable limit and frequency.
Monitoring obligations generally extend to:
- Required monitoring points and equipment quality assurance
- Calibration schedules
- Sampling frequency and laboratory competence
- Data validation and record retention
Handling Abnormal Operation
BAT conclusions call for a risk-based plan covering other-than-normal operating conditions: identifying potential failures, maintaining critical equipment, and monitoring and recording emissions during those periods.
A useful real-world illustration is the Environment Agency's 2025 permit for Powerfuel Portland Limited's energy recovery facility. Its conditions address what happens when continuous-emissions monitors are unavailable or activated-carbon abatement fails, and they require recording the start and end of abnormal-operation periods. They also specify that bottom ash and air-pollution-control residues must not be mixed together.
That's one permit's approach, not a template every UK facility follows — your own permit is the document that governs your site.
Residues and Wastewater
Residue provisions typically distinguish treatment of bottom ash from flue-gas-cleaning residues, and process-water monitoring is usually a distinct permit condition rather than an afterthought. Identify the relevant provisions for your specific plant rather than assuming identical obligations apply everywhere.
How to Manage Schedule 13 Compliance in Practice
Building a Compliance Workflow
A practical approach starts with four steps:
- Confirm the regulated activity — is your plant actually within scope under current definitions?
- Review your permit and Schedule 13 together — don't treat either in isolation.
- Identify applicable BAT conclusions for your plant type and capacity.
- Assign clear responsibility for each requirement internally.
Cross-Checking Permit Against Operations
Run a regular cross-check covering:
- Emissions limits and monitoring frequency
- Operating parameters and maintenance schedules
- Incident response procedures
- Waste acceptance criteria
- Residue management practices
- Reporting deadlines to the regulator
Evidence Worth Keeping
Keep the records that show you met each duty as it arose:
- Monitoring data and calibration records
- Maintenance and operating logs
- Waste acceptance checks
- Incident records and corrective actions
- Regulator correspondence
- Staff training records
These files matter as soon as a regulator questions your compliance history.
Responding to a Suspected Breach
If something goes wrong, the sequence matters:
- Protect people and the environment first. That step always comes before paperwork.
- Record the facts accurately and promptly.
- Take corrective action to stop or limit the issue.
- Notify the regulator where required by your permit.
- Preserve evidence for review.
- Assess whether a permit variation or formal incident report is needed.
What Non-Compliance Can Actually Mean
The Regulations give the Environment Agency several distinct tools, not a single automatic penalty:
- An enforcement notice for an actual or likely contravention
- A suspension notice where pollution-risk conditions are met
- Permit revocation, whole or partial
- Prosecution, treated generally as a last resort
In a February 2026 Environment Agency compliance report, Riverside Resource Recovery Limited recorded carbon-monoxide emission-limit exceedances in Q4 2025. That breached permit condition 3.1.2.
The regulator issued a warning and, at that point, did not intend further enforcement action: no fine, no prosecution. A recorded breach, the response taken, and the stronger powers available in law remain three separate things.
Schedule 13 and Australian Businesses: What to Understand
Schedule 13 belongs to the Environmental Permitting regime for England and Wales. It does not automatically apply to a waste facility located in Australia, regardless of who owns or reads about it.
Finding the Right Australian Framework
An Australian operator should instead identify:
- The relevant state or territory environmental protection authority
- The applicable environmental approval or licence
- Waste classification rules specific to that jurisdiction
- Emissions and monitoring obligations under local conditions
Three examples show how differently this works across states:
| Jurisdiction | Regulator | Framework |
|---|---|---|
| New South Wales | NSW EPA | Environment protection licence with continuous monitoring conditions |
| Victoria | EPA Victoria | A08 Waste to Energy permission (≥3 MW thermal or ≥1 MW electrical) |
| Queensland | State environment department | Environmental Authority under ERA 61, thermal waste reprocessing |
These systems share a broad mechanism: classify the activity, attach conditions to an approval — but the thresholds, terminology, and enforcement powers differ from each other and from the UK model. Treat it as a useful comparison, not an equivalence.
Managing Cross-Border Compliance
If your business operates facilities in both the UK and Australia, or you are an investor or supplier with reporting obligations in both places, map each facility to the jurisdiction where it physically sits.
- Keep a separate legal register for each country
- Do not apply a UK permit condition to an Australian site, or the reverse
Local environmental counsel in each jurisdiction should confirm monitoring, reporting, and waste classification rules on the ground. UK environmental permitting advice is not a substitute for Australian state or territory requirements.
Frequently Asked Questions
What is the purpose of the Environmental Permitting Regulations 2016?
They establish the framework for permitting, controlling, monitoring, varying, transferring, surrendering, and enforcing activities that may cause pollution or environmental harm in England and Wales.
What is Schedule 13A of the Environmental Permitting Regulations?
The correct citation is Schedule 13. It is the waste incineration-related part of the 2016 Regulations, covering operating conditions, emissions, monitoring, and environmental risk controls for incineration and co-incineration plants.
Which waste incineration plants are covered by Schedule 13?
Coverage depends on the plant's purpose, waste type, combustion process, capacity, and permit classification, plus whether it's treated as new or existing. Always check these against current legislation and your specific permit.
What requirements does Schedule 13 impose on operators?
Main duties include operating controls, emissions limits, continuous and periodic monitoring, abnormal-operation procedures, residue management, record-keeping, and compliance with site-specific permit conditions.
Does Schedule 13 apply to businesses in Australia?
No. It's a UK regime for England and Wales. Australian operators should consult their relevant state or territory regulator, such as NSW EPA, EPA Victoria, or Queensland's environment department.
What happens if a waste incineration plant breaches its environmental permit?
The regulator may investigate and choose from several tools, including warnings, enforcement notices, or prosecution. The actual outcome depends on the breach's severity, environmental impact, and the operator's response.
