Environmental regulators gave a key approval to Harbor Point developers Thursday, but said they need to review more data before work that would open a currently-closed toxic waste site can start.
The Environmental Protection Agency and the Maryland Department of the Environment approved a plan to monitor air quality during construction, requiring air samples to be taken every 15 minutes on the site, a former chromium plant. Off-site monitoring will continue at the National Aquarium and the Baltimore City Fire Station in Old Town.
The MDE still needs to determine what level of dust would trigger alarm and require the developer to take action, such as stopping work. A spokesman for the agency said review of collected air samples is expected to finish next week.
Beatty Development's $1.8 billion proposal for the 27 acres between Harbor East and Fells Point requires temporary exposure of contaminated soil to drive pilings for a skyscraper that will house the new regional headquarters of Exelon.Copyright © 2015, The Baltimore Sun
