Offerors shall not alter this established NTE "plug number" in their proposal. This NTE amount serves as a funding ceiling to cover the actual market cost of materials, plus applicable shipping and handling, to provide the chemicals.

These funds shall be used for any modifications to add chemicals throughout each contract performance period. When testing indicates chemical levels are below the required threshold, the contractor shall submit a request to the COR, accompanied by a current supplier quote/invoice for the glycol. Upon written approval, the contractor shall perform the addition. The overall cost for the modification will be reimbursed based on the actual approved market cost of the volume added, up to the established NTE limit.
