Special Message for Grantees Using TDP Material Sourced From Outside of California or Using Manufacturers, Suppliers/Vendors and/or Contractors Offering “Free” Services

All product manufacturers, suppliers/vendors, and/or contractors are required to certify and provide documentation that the material purchased by the grant was derived from only California-generated waste tires that were processed and manufactured into a final product from California. Grantees must understand and be fully aware that if there is inadequate documentation to verify that only California-generated waste tires that were processed and manufactured into a final product in California were used in the TDP, requests for reimbursement may be denied. If reimbursement has been made and it is subsequently determined that the source of the material cannot be verified as only California-generated waste tires or that the tires were not processed and manufactured into a final product in California, CalRecycle may seek reimbursement from the Grantee.

Applicants/Grantees should be wary of product manufacturers, suppliers/vendors, and/or contractors who offer “free” services (such as installation) or a “contribution” as a means to influence the Applicant/Grantee’s purchase/contracting decision. Some “free” services and contributions are actually ineligible costs which the product manufacturers, suppliers/vendors, and/or contractors include in the eligible material cost. Grantees seeking reimbursement, which may include non-eligible costs as part of the material cost, are subject to additional review and/or audit. If it is determined that a reimbursement request includes ineligible costs, all or a portion of the request may be denied. Please consult with your Grant Manager prior to approving an offer which may include these, or similar, “free” services.

Eligible Costs

Eligible costs are limited to:

  • Actual cost of the California-generated tire-derived product material, tax, and shipping up to a total maximum of $5 per passenger tire equivalent (PTE) not to exceed the grant award. (See Tire-Derived Product Certification (CalRecycle 227) form for example of PTE calculation).
  • This cost excludes truck tire buffings, which may be used in the product but cannot be paid for by the grant.
  • Waste tires must have been processed and manufactured into a final product in California or the end-of-life material is sourced in California.
