The six-week C-notification clock versus the first-instance median

Reading order

Start with the object, not with a month. Write whether the file is a municipal C notification, a B permit at an environmental assessment delegation, an A permit at the land and environment court, a Chapter 11 water door, a cooling-tower notification under Ordinance (1998:899), or only a plan-stage screening. Naturvårdsverket’s notification-and-permit page assigns those inboxes. It does not assign a hall month. The sequencing page already owns the order of doors. This page keeps the object named because a six-week start-wait pasted onto a 464-day median invents a third clock.

Then name which six-week sentence is in play. Ordinance (1998:899) writes that a notification-duty activity may start at the earliest six weeks after the notification, unless the supervisory authority decides otherwise. Naturvårdsverket’s C-activity page repeats that some notified activities may start after six weeks, and then writes a different rule: where the authority must decide whether significant environmental effect can be assumed, the activity must not start before that decision. Section 26 c writes that decision as soon as possible and at the latest six weeks from the notification day, extendable with reasons and a new latest date. A start-wait and a significance decision are two bars.

Only then open the first-instance paper as contrast, not as a sum. The 2025 statistics paper, already cited on the sequencing page, publishes national medians after an application exists and says there is no statistic for the time before an application. Naturvårdsverket’s examination page, reviewed 14 July 2025, says the same missing pre-application statistic. Do not add six weeks to 464 days and call the sum a Swedish data-hall miljöprövning. Those remain different objects from different letterheads.

• Name C notification, B or A permit, water door or cooling-tower notice before any week.
• Keep the start-wait six weeks off the significance-decision six weeks.
• A 464-day first-instance median is contrast, not a hall sum.
• The sequencing page already owns the order of doors.

What a notification clock actually is

A notification clock is a dated wait around a complete municipal filing, not a colour on a slide. Naturvårdsverket’s C-activity page puts the filing with the municipal environmental board. Ordinance (1998:899) section 25 says the notification shall contain the particulars, drawings and technical descriptions the authority needs to judge the activity’s nature, scale and environmental effects. An incomplete filing is not a started clock that this page will invent as a week count. The same C-activity page says the municipality charges a fee that varies by municipality, and that if you have heard nothing after six weeks you should contact the municipality. Silence is a reason to write to the inbox. It is not a hall permit.

The start-wait and the significance decision stay apart. Naturvårdsverket’s notification-and-permit page writes that if the authority has not taken a decision within six weeks the activity may, for ordinary notification-duty cases, be carried on. The C-activity page and the supervision page write the stricter bar: where significance must be assessed, the activity must not start before that decision, and starting earlier can be the offence of unlawful environmental activity. Section 26 c allows the six-week significance clock to be extended if nature, complexity, location or scale so require, with information to the notifier about the reasons and the new latest date. An extension is a dated paper. It is not a first-instance median.

A cooling tower is another object on the same ordinance. Ordinance (1998:899) writes a separate notification for constructing or using a cooling tower, with the same earliest-six-weeks start-wait unless the authority decides otherwise. Folkhälsomyndigheten’s cooling-tower supervision page, already in this register, is health-protection guidance. It is not a hall month and not a district-heat contract. The discharge-permits page already owns evaporative water. This page only keeps the tower’s start-wait on its own row.

Permit medians remain a later national paper. The 2025 statistics, compiled from County Administrative Board figures submitted on 12 March 2026 and Domstolsverket figures submitted on 13 March 2026, say a majority of first-instance decisions take one to two years, publish the 464 / 359 / 331-day medians, write condition-change cases at the delegations as about four months, and write that about 28 percent of the courts’ decisions were appealed with an about-811-day appeal average. The paper says the system is dominated by recurring types such as quarries, combustion plants, waste operations and animal keeping. It does not publish a data-hall chapter. It also says the figures are not intended for comparing individual authorities or for legal conclusions about one case. Those sentences stay on the sequencing page as a door-order contrast. They do not become a six-week hall guarantee here.

What named primary sources show

Ordinance (1998:899) shows the six-week start-wait, the content rule in section 25, the cooling-tower notification, and the section 26 c significance clock as amended in 2025. Naturvårdsverket’s C-activity page shows the municipal inbox, the split between activities that may start after six weeks and activities that must wait for a significance decision, the offence warning, the variable municipal fee and the instruction to contact the municipality after six weeks of silence.

Naturvårdsverket’s notification-and-permit page shows the A / B / C inboxes, the about-6,000 and about-20,000 national counts, and the sentence that an ordinary notification-duty activity may proceed if no decision has been taken within six weeks. The supervision page shows copies to other authorities, the possibility to hand a C case to the County Administrative Board for special reasons, and the same extendable six-week significance decision. The 2025 statistics paper and the examination page remain the first-instance contrast already owned on the sequencing page.

Related pages already in this register: the parent environmental matrix, EIA anatomy, permit sequencing, noise-and-permit-timelines, and discharge permits. Operator news for Horndal, SWE04 or Microsoft’s 2021 municipalities is not used here as a notification clock.

A matrix instead of one miljöprövning month

The table is a permission table. A filled cell is a claim the named URL can carry. An empty cell means this page will not invent the missing hall date or the missing data-centre chapter.

Do not add the six-week start-wait to the six-week significance clock and the 464-day court median and call the sum a Swedish data-hall miljöprövning. Those remain different objects from different letterheads.

Common misreads

The first misread is to treat the six-week start-wait as a granted permit. The wait is a statutory earliest start, unless the authority decides otherwise. The second is to treat municipal silence after six weeks as approval. The C-activity page tells you to contact the municipality. The third is to staple the significance-decision clock onto the start-wait and call them one bar. Where significance must be assessed, the activity must not start before that decision, and that decision can be extended.

The fourth is to add six weeks to the 464-day 2025 court median and print a Swedish hall miljöprövning. The median starts when an application is filed. The examination page says there is no statistic for the time before the application. The fifth is to treat the about-20,000 notification-duty count as a data-hall census. The sixth is to treat a cooling-tower notice as a district-heat contract or as a Chapter 11 water permit.

What to ask next

If a brief prints one Swedish miljöprövning month, ask which named URL uses that month for a C start-wait, a significance decision, a cooling-tower notice or a first-instance permit median. If the URL only shows a national count, a quarry row or a company groundbreaking date, the brief has already left the source.

Then open the parent environmental page, the sequencing page and the EIA-anatomy page. Those pages already own the topic matrix, the order of doors and the document names. This page only asks whether the six-week bars stay on their own rows.

1. Is the live paper a C notification, a B or A permit, a water door or a cooling-tower notice?
2. Which six-week sentence is in play — start-wait or significance decision?
3. Has anyone treated municipal silence as a permit?
4. Has a 464-day median been added to a six-week bar?
5. Has a data-hall chapter been invented?

What this does and does not prove

This page proves that Swedish primary sources already publish a municipal six-week start-wait and a separate six-week significance-decision clock, and that those clocks are not the 2025 first-instance medians. It proves that about 6,000 and about 20,000 are national activity counts, not a hall classification.

It does not prove how many weeks a named Swedish hall will wait. It does not classify a generator yard or a cooling loop. It does not treat silence as approval.

Empty cells stay empty. Until a later primary source names a Swedish hall’s notification with a dated complete filing and a boundary, the clock stays a method, not a census.
