Dear Ms. Kerlann Bunch, Permit Manager,

We are requesting that IDEM convene a Public Hearing with regards to Hartford Iron and Metal. There has been a significant amount of rain during the past several weeks with a substantial of water runoff not being captured by the existing system. There has been no demonstration of how the proposed system will be successful in treating the runoff water issue. Additionally, the proposed system amounts to an expansion of the existing facility.

Recent investigation and research indicates that fugitive dust contaminated by significant amounts of arsenic, lead, chromium, cadmium and nickel is being deposited on the surrounding landscape in the residential neighborhood – upwind as well as downwind from Hartford Iron and Metal. This suggests that the contaminated fugitive dust is not being carried by the wind, but is generated onsite by ongoing Hartford Iron and Metal activities. The contaminated dust is then washed during rainfall into the stormwater drainage system. This stormwater needs to be addressed as well as the stormwater coming directly off of the site.

Please notify us of your intention.
Thank you,
[your name]
