Residents of Méry-sur-Oise rally against the quarry project in Saint-Ouen-l’Aumône

For several weeks, the inhabitants of Fond-de-Vaux and members of Adepfv have been showing their opposition to the quarry project 500 meters from their homes.

Some thought it was buried, but the project open pit at Fond-de-Vaux is talking about him again.

Dormant since 2018, this dossier carried by the Ect group provides for the operation, for eight years, of a former mushroom farm in an open-air quarry in this district straddling the municipalities of Saint-Ouen-l’Aumône and Mery-sur-Oise, in the Val-d’Oise.

First mobilization in 2017

Four years after a first outcry from the inhabitants of Fond-de-Vaux, the residents of this hamlet of Méry-sur-Oise – whose houses are 500 m from the planned site – are mobilizing again.

It was the announcement of the opening of a public inquiry on this subject, Monday, November 22, 2021, which put the chip in their ears.

Saturday, November 20, they were present at the Méry market to sign a petition. Online at, it had collected more than 13,900 initials Thursday, November 25. All fear the nuisances associated with such a project: traffic congestion with several daily movements of trucks, noise, vibrations, dust …

Quick mobilization

“Our mobilization was very rapid,” explains Jérôme Durieux, elected opposition merysian (Generation. S) and member of the association for the defense of the environment and the heritage of Fond-de-Vaux (Adepfv). We contacted the Val-d’Oise environment association and we are also working with a lawyer. In addition to the nuisances, we fear the use of this quarry to bury the waste of Greater Paris. “

For its part, the City of Méry is on the same wavelength as its inhabitants.

“We haven’t changed our mind. We are still opposed to this mind-blowing project from an environmental point of view and which will only cause nuisance to the Mérysiens. We do not understand why this project is of public utility when it is strictly private. “

As for the Ect group, it emphasizes the security of the site to justify the usefulness of this project and says it is open to dialogue with local residents.

“Our goal is to enhance the basement and secure these quarries. Their ceilings are collapsing in places and illegal parties are held in the galleries. As with any classified installation, we are subject to regulations and supervision by the prefecture. We are also able to set up a steering committee with the inhabitants who will be able to visit the site regularly. “

Julien GolaszewskiDeputy Director of the Ect Development Department and Chairman of the Fond-de-Vaux Development Company.

Regarding the waste from Greater Paris that could backfill the site, the Ect manager says that these will only represent a tiny part of the quarry’s backfill: “It will mainly be inert waste from local sites like those of the he metropolitan area of ​​Cergy-Pontoise. We will make sure that all land deposited will not be polluted, and if so, we will treat it. We provide answers to the inhabitants, but we also feel a dogmatic opposition that falls under the Niby (not in my backyard, not in my garden in French). »

Request for preemption

For residents, this accusation of defending their short-sighted interests remains unfounded. “We have environmental, technical and public health arguments to make,” protests Jérôme Durieux.

The Adepfv, whose general assembly will be held this Friday, November 26, in Méry, also intends to ask the municipalities of Saint-Ouen-l’Aumône, Méry-sur-Oise and Smapp (Mixed union of the plain of Pierrelaye in charge of the future forest, Editor’s note) to pre-empt the entire career.

This solution would indeed make it possible to put an end to the project… but not at any cost.

“We had already considered this solution four years ago,” explains Pierre-Édouard Éon. If the sale is opened after a favorable opinion from the investigation commissioner, we will do what is necessary to preempt, but not at the price requested by the owner which is much too high for this land. “

Friday December 10, 2021, a public meeting with Ect will be held from 7 p.m. to 9 p.m. at the town hall of Saint-Ouen-l’Aumône.
