Publicity for applications with an environmental statement

Environmental statement publicity runs to a longer clock than ordinary planning publicity. Where an application is accompanied by an environmental statement, the minimum period for representations is 30 days rather than the 21 days that applies to publicity under article 15 of the Town and Country Planning (Development Management Procedure) (England) Order 2015. The requirements sit in the Town and Country Planning (Environmental Impact Assessment) Regulations 2017, and they cover the notices, where the statement must be available, what may be charged for a copy, and what happens when the authority asks for more information.

For a developer programming a major application, the publicity rules are not administrative detail. They set the earliest date a decision can be taken and they create a second full consultation period every time the environmental information changes.

The 30 day period and why it is longer

The authority must publicise the application by site notice and by notice in a newspaper circulating in the locality, and the notice must state where the environmental statement can be inspected, how copies may be obtained, and that representations may be made within a period of at least 30 days.

The longer period reflects what is being consulted on. An environmental statement for a substantial scheme runs to several volumes with technical appendices, and 21 days is not a realistic period in which a parish council or a residents' group could read it.

Two practical points follow. The 30 days is a minimum, and authorities can and do allow longer on complex schemes. And the period runs from the later of the relevant publicity steps, so a site notice posted three days after the press notice pushes the end date out.

Plan the programme from the last publicity step, not the first. Applicants who diarise from the validation date are routinely a week out.

Where the statement has to be available

The statement must be available for public inspection, and in practice that means three things: a copy at the authority's offices or another accessible location named in the notice, publication on the authority's website alongside the rest of the application documents, and copies obtainable by anyone who asks.

The website version matters most, and it is where things go wrong. Large appendices split across dozens of files with unhelpful names are technically available and practically not. A resident who cannot find the noise chapter will say so in a representation, and an authority conscious of challenge risk may extend the period or repeat the publicity.

Three things worth doing before submission:

1. Name the files so a lay reader can find a chapter, using plain titles rather than internal document numbers.
2. Keep individual files to a size that downloads on a domestic connection.
3. Supply a single contents document listing every file in the statement.

Getting the documents onto the register correctly is part of the authority's duty, and the article on the statutory planning register sets out what has to appear there.

Charging for paper copies

The Regulations permit a charge for a copy of the environmental statement, and the charge must not exceed a reasonable amount that corresponds to the cost of printing and distribution. It is not a revenue opportunity and it cannot be used to deter requests.

In practice most requests are satisfied electronically at no cost, which is both quicker and less costly. Where a paper copy is needed, the applicant usually bears the printing cost as a matter of practicality, since it is the applicant who holds the print-ready files.

Expect requests from parish councils, local amenity societies and occasionally a single determined neighbour. Budget for a handful of full paper sets on a scheme of any size and do not make the process difficult, because obstruction here is the kind of detail that turns up in a judicial review pre-action letter.

Consultation bodies and their role

Separately from public publicity, the authority must send a copy of the environmental statement to the consultation bodies and give them at least 30 days to respond.

The bodies vary with the scheme. Natural England for designated sites, protected species and soils. The Environment Agency for flood risk, water quality, groundwater and waste. Historic England for designated heritage assets at the relevant grades. The lead local flood authority for surface water. The highway authority or National Highways depending on the road network affected. Where a scheme affects a railway, a canal or an aerodrome, the relevant operator or safeguarding body.

Their responses carry real weight because they are the technical evidence the authority relies on. An objection from a statutory consultee that is not resolved is the most common reason a major application stalls.

Engage them before submission rather than through the consultation. A statutory consultee reading a chapter for the first time during the 30 day period, with no prior discussion, will default to asking for more information.

Requests for further information

This is the provision that moves programmes. Where the authority considers the environmental statement incomplete, it can require further information, and it can require evidence to verify information already supplied.

The consequence is procedural rather than technical. Further information supplied under that provision has to be publicised in the same way as the original statement, which means another round of notices and another period of at least 30 days for representations and for the consultation bodies.

So a single missing chapter can add six weeks or more to the determination, and two rounds are not unusual on a contested scheme. The discipline that avoids it is scoping: agree the scope with the authority and the consultation bodies formally, address every scoped matter, and say in the statement where each scoped matter is dealt with.

The same publicity logic applies to substantive amendments made during determination, which is the subject of the article on re-consultation after amended plans. Where an amendment changes the environmental effects, expect a fresh round rather than a targeted re-consultation.

The 16 week determination period

The determination period for an application accompanied by an environmental statement is 16 weeks, rather than the 13 weeks for other major development. That period is set by the procedure order and runs from validation.

Very few EIA applications are decided within it. Extensions of time agreed in writing are normal, and a planning performance agreement setting out a timetable and resourcing is worth having on anything substantial. The article on cross-boundary sites and applications to two councils covers the additional complication where two authorities are each running their own 16 weeks.

Two consequences for programming. Any further information round effectively resets the realistic decision date, so build contingency around the scoping outcome rather than around the statutory period. And remember that an appeal for non-determination is available once the period expires, which is a lever rather than usually a good idea on an EIA scheme.

The non-technical summary and its audience

The non-technical summary is a required part of the environmental statement, and it is the document the public and most councillors will actually read.

Write it for a reader with no technical training and no access to the main chapters. That means describing the development in ordinary words, explaining what was assessed and why, stating the effects plainly including the adverse ones, and setting out the mitigation and who carries responsibility for it.

The failure mode is a summary assembled by pasting chapter conclusions together. It reads as defensive, it uses terms nobody outside the industry knows, and it draws exactly the representations it was meant to avoid. A summary that concedes the residual adverse effects honestly is more persuasive at committee than one that claims everything is neutral.

The statement itself must be prepared by competent experts, and it has to be accompanied by a statement of their relevant expertise and qualifications. An Environmental Impact Assessment is one of the report types where qualified professional input is legally required under the 2017 Regulations, so an AI-assisted draft can only ever be a starting structure for those experts rather than the assessment itself.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
