MADISON - Roberta Walls, a veteran Department of Natural Resources staff person working in the La Crosse and West Central Wisconsin areas, has been tapped to be the agency's new contact on industrial sand mining issues.

Walls will serve as the initial point of contact on sand mining for public, private, legislative and media inquiries on the DNR's regulatory authorities and interaction with the industrial sand sector. She will be based in the DNR's La Crosse office. Walls replaces Deb Dix, who was serving in an interim capacity and has returned to her position in the Environmental Enforcement Program.

"Roberta brings with her a wealth of knowledge and experience working with the public and the industry on sand mining," said Mark Aquino, director of the DNR Office of Business Support. "We are very excited to have her on board as our agency lead for sand mining."

Walls began working on sand mining issues for the agency when she joined the DNR in 2008 as part of the wastewater and stormwater programs. Prior to the DNR, Walls worked as a certified wastewater operator in Lynxville, and in the private sector worked with international companies as an analytical chemist and chemical coordinator for industrial wastewater treatment.

"I'm excited to begin this new phase of my career at the DNR," said Walls. "Whether it's my experience in sand mining, local governments or the private sector, I'm looking forward to putting those skills to work on this challenging issue for the state of Wisconsin."
