Editorial review 2026-09-12 · Jurisdiction: Sweden — Environmental Code chapter 10 as explained by Naturvårdsverket

Contaminated land is not a cleared pad — a map pin is not a chapter 10 paper

Is a Swedish industrial plot already a buildable hall pad because a screening slide is green, or because someone holds a dated Environmental Code chapter 10 file? Naturvårdsverket’s 2024 guidance on responsibility for remedying environmental damage, used here, says chapter 10 holds who must investigate and aftertreat land, water, groundwater, a building or an installation that is so contaminated that it can cause harm or inconvenience to human health or the environment. Avhjälpande, as chapter 10 section 1 records it, is investigation, aftertreatment and other measures. The polluter-pays sentence in chapter 2 section 8 is the starting principle. Chapter 10 section 2 names the verksamhetsutövare: the person who conducts or has conducted an activity, or took a measure, that contributed to the contamination. Chapter 10 section 4 says that duty is to perform or pay for the measures that are needed, in a reasonable extent; time elapsed, the duty to prevent later harm, and whether the contribution was only limited, all sit inside that reasonableness test. Contributors answer jointly and severally. Naturvårdsverket’s PFAS-supervision page, used here, repeats two conditions before chapter 10 can be applied: a contamination injury must exist, and it must be able to cause harm or inconvenience. The supervisory authority carries that burden of proof. A MIFO Fas 1 desk study can be enough in some cases; a verifying sample can be needed in others. Naturvårdsverket’s inventory page is a national method paper for suspected sites. It is not a hall laboratory certificate. EBH-stödet, as the 2024 guidance and the quality manual used beside it record, is the county-administrative-board database of contaminated objects. EBH-info is a simplified public reading of state-funded objects and national statistics. A pin in that family of tools is a screening object. It is not a closed aftertreatment, not a bygglov and not a reserved megawatt. Microsoft’s 16 November 2021 Sweden-region note names Gävle, Sandviken and Staffanstorp. EcoDataCenter’s Falun campus page names Falun. Google’s Horndal page names Horndal. atNorth’s 23 February 2026 SWE04 note names Sollefteå. evroc’s 3 February 2025 Arlandastad note names Arlandastad. None of those pages is a MIFO report, an aftertreatment decision or a chapter 10 duty finding for those cadastral units. The environmental-permits hub and the water-operations page already own neighbouring papers. This page only asks which published contamination object the hall file is sitting on. This is orientation, not counsel.

General orientation. Assess the specific project separately. Applies to: Readers placing a clean-pad, brownfield-cleared or EBH-pin sentence on a Swedish hall land file.

Reading order

Seat the statute chapter before any coloured pin. Environmental Code chapter 10 is an aftertreatment chapter. It asks whether a contamination injury exists and who, in a reasonable extent, must investigate or treat it. Write the object, the suspected substance family and the dated paper on one line before you say the pad is clean.

Then keep the operator and the later acquirer on separate rows. Chapter 10 section 2 is the verksamhetsutövare who contributed. Naturvårdsverket’s 2024 guidance also records a fastighetsförvärvare track. A share-purchase slide that never names the cadastral unit is not that later-acquirer paper. A campus press note that names a town is not a duty finding.

Then keep inventory, sampling and aftertreatment on their own clocks. A MIFO Fas 1 desk study is a method step. A verifying sample is a later step. Aftertreatment is a still later object. Naturvårdsverket’s inventory page, read on 12 September 2026, even records a 15 September 2026 clock for 2027 verifying-sampling grants. That is a state-funding clock. It is not a hall laboratory week.

Then keep named project rows as geography. Microsoft’s 16 November 2021 municipalities, EcoDataCenter Falun, Google Horndal, atNorth SWE04 Sollefteå and evroc Arlandastad stay operator papers. This register does not publish a MIFO class or a chapter 10 decision for those cadastral units.

  • Chapter 10 asks who investigates and treats, not whether a slide is green.
  • Verksamhetsutövare and later acquirer are different rows.
  • A MIFO desk study is not aftertreatment.
  • An EBH pin is screening, not a closed file.

What a chapter 10 duty and an EBH pin actually measure

Chapter 10 measures a contamination injury and a reasonable duty. Naturvårdsverket’s PFAS page is explicit that the supervisory authority must show both the injury and the risk of harm or inconvenience. A marketing sentence that the plot “has industry history” is not that showing.

A MIFO inventory measures a method class for suspected objects. Naturvårdsverket’s inventory page is national guidance for that method, including later PFAS and sediment rows. It does not classify a named hall. It does not publish a litre or a milligram for Horndal or Arlandastad.

EBH-stödet measures what county boards have registered. EBH-info measures a thinner public slice. Neither tool is a bygglov, a startbesked, a line concession or a reserved feeder. A missing pin does not prove the plot is clean. An existing pin does not prove the hall already holds an aftertreatment decision.

Operator notices measure existence and intention. A named campus town is a paper-class geography. It does not prove who the verksamhetsutövare is, whether a later acquirer was told, or whether a sample has been taken.

What named primary sources show

Naturvårdsverket’s 2024 aftertreatment-responsibility guidance remains the dated national commentary for chapter 10, the verksamhetsutövare row and the later-acquirer row. The PFAS-supervision page remains the dated commentary for the two conditions and the burden of proof. The inventory page remains the dated method paper, including the 15 September 2026 grant clock for 2027 verifying samples.

Environmental Code 1998:808 chapters 2 and 10 remain the statutory papers. The environmental-permits hub remains the neighbouring letterhead. Named operator rows remain geography.

No cited source here publishes a project-specific MIFO report, a chapter 10 duty decision or a reserved hall megawatt created by a green screening slide.

A matrix instead of one clean-pad slogan

Draw one page with object rows and evidence columns. Chapter 10 duty, MIFO inventory, verifying sample, EBH pin and a named campus town are different columns. Empty cells stay empty. A campus press note is a geography footnote, not a laboratory file.

Do not invent a hall milligram or a national clean-up week from the handbook. Those remain method facts from dated Naturvårdsverket pages.

Common misreads

The first misread is to treat a green screening slide as a chapter 10 close-out. The statute asks for an injury and a duty, not for a colour. The second is to treat an EBH pin as a building ban, or a missing pin as a clean certificate. Both are inventory objects. The third is to collapse the verksamhetsutövare and the later acquirer into one purchaser slogan.

The fourth is to treat a named campus town as proof that a hall already holds a MIFO class. The operator page named a town. It did not publish the sample. The fifth is to treat the 15 September 2026 grant clock as a hall laboratory week. The sixth is to invent a milligram or a reserved megawatt. The seventh is to collapse this page into the water-operations page or the environmental-permits hub.

What to ask next

Ask which dated paper anyone is quoting — a MIFO step, a verifying sample, a chapter 10 duty finding or only an EBH pin — and which cadastral unit it names. Ask who is written as verksamhetsutövare. Ask whether a later acquirer paper exists.

Then open the environmental-permits hub, the water-operations page, the flood-risk page and the due-diligence page. If the operator will not name the object and the date, record the gap. Do not fill it from a clean-pad slide. This page is not legal advice.

  1. Is the paper a MIFO step, a sample, a chapter 10 finding or only an EBH pin?
  2. Which cadastral unit and which substance family does it name?
  3. Who is written as verksamhetsutövare — and is there a later-acquirer row?
  4. Has a missing pin been treated as a clean certificate?
  5. Has a campus town been treated as a laboratory file?

What this does and does not prove

This page proves that Naturvårdsverket already publishes chapter 10 as an aftertreatment duty with a verksamhetsutövare row, a later-acquirer row and a method inventory that is not a hall laboratory certificate — and that those facts are not a reserved hall megawatt.

It does not prove that a named Swedish hall sits on a named contamination class. It does not invent a milligram for Horndal or Arlandastad. It does not treat a campus press note as a MIFO report.

Empty cells stay empty. Until a later primary source names the object, the duty holder and the dated paper, the contamination clock stays a method, not a census. DataCenterSweden records the method.
