Restrictions on Products Receiving STA Lab Results
Print this Article | Send to Colleague
The USCC is clarifying Seal of Testing Assurance (STA) Certified Compost Program procedures as we continue to improve and grow participation. We have recently upgraded our STA map and list. Now anyone can see their STA products and derivative products listed under each of their STA facilities. Specifiers and participating laboratories will more easily be able to see which products are in the STA program and which are not. Often multiple products are enrolled by one company and, with the new website, we now show more clearly what is enrolled.
For STA participants, please ensure, when you submit your chain of custody form with your product sample to the laboratory, that the product name on the form matches what you have enrolled in STA as reflected on our webpage. The labs will not be able to give you test results on STA-branded Compost Technical Data Sheet (CTDS) paperwork if the product names do not match.
If you have any concerns or need clarifications, please contact STA Program Manager Hilary Nichols to add products or correct your STA registration.
