Sports Fields Procurement and Maintenance

Other considerations beyond those covered here, including the impact attenuation performance of materials, must be considered before choosing a material.

Proposed procurement goals: 
  • Eliminate crumb rubber for infill in all sports fields
  • Eliminate artificial turf for all sports fields 
  • Require natural turf grass for all sports fields
  • For natural grass turf, require organic turf management practices
  • Where artificial turf cannot be avoided, 100% of turf selected: 
    • Does not use turf or filler that advertises antimicrobial protection
    • Surface and synthetic fillers have been tested and do not contain: 
      • PFAS
      • PVC
      • Benzothiazoles, isobutyl ketone, bis(2-ethylhexyl) phthalate, or PAHs
      • Carbon nanotubes (CNTs) 
      • All toxic metals including lead
    • Require strict VOC/SVOC testing for products that at a minimum are tested for: methyl isobutyl ketone, benzothiazole, toluene, styrene, aniline, m/p xylenes, o-xylene, 4-tert-octylphenol, benzene, toluene, ethylbenzene, m/p-xylenes, formaldehyde, pyrene, and styrene
    • Do not purchase shock pads that contain crumb rubber or PVC 
    • Use plant-based or mineral-based infill over synthetic infill
    • Publicly post information on surface material use and VOC/SVOC testing on all fields where artificial materials are used
    • Require disclosure of PFAS in all products considered for purchase: Michigan Executive Directive 2021-8, Reducing State Purchases of Products Containing Intentionally Added PFAS 
    • Require product ingredient disclosure on all contracts for the turf, filler, and shock pad
    • Require end of life take back, recycling, or extended producer responsibility programs for products purchased
