The last update to the site was 10/1/2025.  Updates to the site will start again when the Federal government resumes operations.

Mine operators sending in respirable dust samples need to mail them to the following address: 

Respirable Dust Processing Laboratory
Pittsburgh Safety and Health Technology Center
626 Cochrans Mill Road
Building 38
Pittsburgh, PA 15236-3611

In 2016 and earlier, dust samples were mailed to a PO Box.  This changed in 2016 and was reflected in the updated versions of 30 CFR §§70.210 and 71.207.

Some pre-printed boxes may display the older PO Box information, which is resulting in samples being returned by the US Postal Service.
