Yorkshire Water’s warning about the aquifer being “highly vulnerable” is in a letter about the plan, published on North Yorkshire Council’s planning portal.
In a statement, a Yorkshire Water spokesperson said the company is committed to doing what is right for its customers and the environment.
The firm’s role in this planning application is “solely to consider” its impact on the company’s water sources, based on the information provided and the role it has as a consultee.
Yorkshire Water has asked for additional detail on drainage design and maintenance, observation boreholes, decommissioning of the site, and the storage of fuel and foul waste, the spokesperson said.
They added: “We will continue to work with the planning authority as this application progresses and submit any further concerns that may arise in relation to our assets and water sources.
“However, the final decision on acceptability rests with the Environment Agency, Health and Safety Executive and the planning authority.”
The Environment Agency has confirmed the Flamborough Chalk is a “principal aquifer,” which, the agency said, provide “strategically important” water supplies and the flow of water to rivers.
An EA spokesperson said the agency had received “an environmental permit application” from Egdon.
“This is in relation to proposed activities at its Weaverthorpe well site. As with all applications we are carefully assessing this alongside consultation responses and will update with a final decision in due course,” the spokesperson added.
