Supervisors are seeking a public hearing about plans by chemical manufacturer Reaxis Inc. to install a 3,200-gallon reactor in its plant at 941 Robinson Highway.

"I personally think it's too close to some residences and some commercial areas, and they have a history of a spill," Supervisor Brian Coppola said Aug 12.

In 2002, a hydrochloric acid tank leaked, causing some evacuations and illnesses, he said.

The company -- formerly Pitt Metals and Goldschmidt Industrial Chemical Corp .-- has applied to the state Department of Environmental Protection for approval under the Air Pollution Control Act.

Mr. Coppola said the DEP did not respond to the township's March request for a public hearing, so he would send a follow-up letter.

Commissioners have established a Traffic Impact Fee Advisory Board, set an interim impact fee schedule and scheduled a Sept. 8 public hearing on a proposal to change the Mayview State Hospital site from rural residential zoning to business park zoning.

Traffic impact fees are charged to developers based on how much traffic they will generate, with the money used to build roads. The advisory board will help determine what a fair fee would be, based on the conditions of township roads and what the future road needs will be.

The interim fee of $1,000 per trip generated by a development can be assessed starting when the advisory board is seated. The township will be advertising for advisory board members.

As for Mayview, the township is looking at rezoning as a way of protecting its interests in the development of the property. A task force including state officials, county officials and representatives of other nearby municipalities is looking at how the property should be used after the hospital closes.

Manager Mike Hoy said that the eventual zoning would likely be different, possibly some sort of mixed-use village-style concept, but advised that the commissioners get new zoning in place to prevent development proposals they don't want.
