Who was allowed to participate in the TROA negotiations?

All TROA negotiation plenary sessions and most working group and committee meetings were open to all interested persons. The Secretary of the Interior, States of California and Nevada, the Pyramid Lake Paiute Tribe, and Sierra Pacific Power Company (now Truckee Meadows Water Authority) were mandatory signatories to TROA. Over the 18 years of negotiations, the negotiators entertained proposals submitted by any person for inclusion in TROA.
