Controversial changes to an oil and gas ordinance have been approved by Wilmington Township Supervisors.

A public meeting held Monday night was standing room only with overflow into the Administration Building's parking lot.

The turnout was triggered by concerns over fracking and proposed changes to an already existing oil and gas ordinance.

"I think the industry preys on the fact that small townships like this, don't have the information they need in front of them and they're just going to go ahead and turn this thing out just as they've always done things before," said Wilmington Resident Carrie Hahn.

The changes to the ordinance would strengthen some aspects, such as requiring compressors to be enclosed to reduce noise.

However, some have concerns that fracking wouldn't be limited to areas zoned "industrial." As well as, concerns over the distance wells could be from their property and homes.

"People think we're fighting fracking, we're not fighting fracking. We're fighting to keep them in safe areas and industrial zones where they belong," said Resident Judi Hartzler.

Hartzler pointed to pictures of her grandchildren when she told 21 News the only approved well pad in Wilmington is 100 yards from her property.

"Our daughter and son-in-law will not feel comfortable letting those two beautiful children that close to something so dangerous," said Hartzler.

After months of review and public comment, township supervisors approved the changes in a vote of three to zero.

All three supervisors declined on-camera interviews to discuss their vote.
