Authorities in the US state of Maryland have proposed a chain of custody for synthetic turf fields.

This bill requires the State Department of the Environment to establish a uniform system to track the chain of custody of synthetic turf—from its production to its installation to its eventual disposal—on sports and playing fields in Maryland.

On February 15, 2023, Legislative Director Kevin Kinnally testified before the House Environment and Transportation Committee in support of HB 0299 – Environment – Synthetic Turf – Chain of Custody with amendments. MACo worked with bill sponsor Delegate Mary Lehman on amendments clarifying certain definitions and recognising certain difficulties in tracking turf infill.

The plan is that the department will serve as the custodian for chain of custody information and develop and maintain a website that includes chain of custody information. The system should be functional by 1 January 2024.
