Safety and prevention during any works

Works next to the pipeline: more about the process and regulation

As an important figure in the life of your region, you have certain responsibilities for safety and prevention during any works carried out near to existing networks (of water, electricity, gas, telephone lines, etc.).

When works are planned close to one of our pipelines, you can assume several roles:

As a public service, you must inform your constituents of their legal obligations with regards to declaring work projects, and direct them to the website www.reseaux-et-canalisations.gouv.fr. Contracting agents, construction companies, network operators and individuals can find information leaflets on the procedures to follow on the website.

 

What needs to be declared on the single service point?

If you are declaring works as a contracting agent:

  • You declare your work projects to operators who have a network close to your proposed work site.
    The declaration is made in 4 stages:
    • You identify yourself.
    • You mark out the area of your proposed work site on an IGN underground map provided by the Single Service Point.
    • You fill in the DT forms. A DT form must be addressed to each operator affected by the work site. This must be completed as far in advance of the project as possible so that any incompatibilities with the existing network can be quickly identified.
      • These forms and the IGN underground map are then sent to the operators involved either by post or email.
      • GRTgaz must respond to you within 9 days (which can be extended up to 14 days if the forms are sent by post). If there is no reply from us within 3 months, you must renew your DT.
  • If you must undertake emergency works, you are exempt from the DT. However, you must still consult the single service point to see if there is a high-pressure natural gas pipeline close to your proposed work site.
    Where there is a pipeline, you cannot begin the works until after you have contacted GRTgaz and obtained from us the safety instructions to follow.

If you are declaring works as a work agent:

  • Before beginning works on public or private land, you are obliged to consult the single service point to check the locations of our high-pressure gas pipelines and declare your proposed work site using the DT and DICT forms.
    The declaration is made in 4 stages:
    • You identify yourself.
    • You mark out the area of your proposed work site on an IGN underground map provided by the Single Service Point.
    • You fill in the DT-DICT forms. Each sub-contractor is required to complete a DICT and provide a copy to each operator.
    • These forms and the IGN underground map are then sent to the operators involved either by post or email.
      You may not begin works until you have received our recommendations and safety instructions to follow at the first appointment with GRTgaz.

If you are a network operator

You must validate your identity on the single service point to reference your network.

There are two possible procedures:

  • With a digital authentication certificate provided by the Ministry of the Interior via the National Secure Credentials Agency (www.ants.interieur.gouv.fr).
  • With a log-in and password provided by the Ministry for Sustainable Development.

After registering the areas covered by your networks that are in service, you should consider declaring all new construction and modification projects (extensions, reductions, abandonment, etc.). 

As a network operator, you will receive the DTs and DICTs filled in by the work agents. You must respond to them by the legally-specified deadline.

 

What information should be included in your responses to DT/DICT declarations?

You must include any useful recommendations and safety information in your reply, so that the works can be carried out in complete safety.
This means that you must be able to predict any accidents that may possible occur, so that security measures can be put in place as quickly as possible if any damage is caused.

 

How soon should you respond to DT/DICT declarations?

In theory you must respond to DT/DICT declarations within 9 days - bank holidays not included - with a receipt of confirmation.

There are two exceptions to this rule:

  • The deadline can be extended to 14 days when a DT is sent to you by post.
  • You have 14 extra days to respond should you need to visit the site to identify the network with the declaring party.
