The participating facilities reserve the right to reject any or all quotes received. Any inability to deliver product or to hold pricing will immediately declare any agreement on price and delivery null and void at the discretion of each participating facility.

Chemicals specified for bulk delivery shall not exceed DOT legal limits. It is the intent of participating facilities to receive full load bulk deliveries, except as noted in “Special Notes and Conditions.” It is the responsibility of the supplier to coordinate any split delivery; however, local facilities actively participate in the process.

Ordering will be conducted by each facility. Invoices shall be directed to the facility receiving the delivery. The facilities agree to cooperate with the chemical suppliers to minimize short load deliveries. However, short load deliveries may be required.


  • We are requesting quotations of 15% Bulk Sodium Hypochlorite Solution (available chlorine by volume). This is understood to be 12.5% minimum available chlorine by weight at delivery and shall be certified for compliance with the ANSI/NSF Standard 60 for drinking water additives. Said certification shall be by either NSF International or Underwriters Laboratory. We require this certification on all bulk loads, as split loads are often between water supply and wastewater treatment facilities.
