Dover-based engineering firm ILC Dover demonstrated for the press its “tunnel plug” designed to minimize flooding in subway systems, NewsWorks’ Alyssa Wesley reports.

The Delaware General Assembly’s Natural Resources committee voted Wednesday to release a bill that would amend the Coastal Zone Act to allow the repurposing of abandoned or contaminated industrial sites, WHYY’s Zoë Read reports. The legislation, which aims to make Delaware more business-friendly, would create a permitting process for the redevelopment of 14 industrial sites. Supporters of the bill say the current CZA, which only allows an abandoned site to be repurposed for its previous use, is too restricting on businesses and prevents new businesses from locating to Delaware. Opponents of the bill say their biggest concern is the risk of spills from bulk product transfer along the river and that “there hasn’t been enough public input on the legislation, which has been in the works for three years.”
