Home Depot is in the midst of an EPA investigation

Home Depot disclosed an ongoing Environmental Protection Agency investigation into its lead safety practices related to its installation services business.

In an SEC filing published on Thursday, Home Depot disclosed an investigation by the EPA's criminal investigation division into its compliance with lead-safe work practices. Home Depot is currently cooperating with the EPA, having previously responded to civil document requests from several EPA regions.

Home Depot received subpoenas from the District Attorney of Alameda County, California in November 2013, working with various District Attorneys and the California Attorney General's office, seeking information about Home Depot's disposal of hazardous waste at its California facilities.

The District Attorneys are seeking monetary penalties and changes to Home Depot's operations in this vein.

Though SEC regulations require companies to disclose information about proceedings if there's reasonable belief that the proceedings may result in monetary sanctions of $100,000 or more, Home Depot said it "does not expect the outcome to have a material adverse effect on its consolidated financial condition, results of operations or cash flows."

In February, the Atlanta-based retail giant posted fourth quarter net earnings of $1.74 billion.
