NEW YORK — The U.S. Department of Justice has proposed a settlement with a now-defunct metals company in a case involving a hazardous lead scrap site in Ohio.

The agency wants Senser Metal Co. and its now-deceased owner, Saul Senser, to reimburse it for the costs associated with remediating the United Scrap Lead Superfund Site in Troy. The agency also charged Senser with improperly diverting money to himself during the company’s bankruptcy.

The proposed amended decree, issued Jan. 15, would require the executor of the Senser estate, Kenneth Senser, to pay $486,500. That is about $73,000 less than the figure previously agreed upon in March 2012, which the government later determined to be beyond the estate’s ability to pay.

The settlement would also resolve the United Scrap Lead Respondent Group’s Superfund claims against Senser for $21,500 in response to costs it incurred in cleaning up the site.

With Tuesday’s notice, the federal government has opened a 30-day period for public comment on the proposal.
