Allnex permit application concerns river advocates
WALLINGFORD — Allnex’s application for a change to its waste water discharge permit has some river advocates calling for a public hearing after filings showed the chemical company had 17 discharge violations since February 2012.
Allnex wants to change its discharge permit because of plans to manufacture modified or new products at the South Cherry Street facility.
The products are similar to those already manufactured on site and will be produced with existing equipment. The modification includes monitoring for a new parameter, tetrahydrofuran, according to a report by the state Department of Energy and Environmental Protection. Tetrahydrofuran is a clear, colorless liquid used in adhesive and sealant chemicals, according to the compound summary on the National Institutes for Health website.
