SIEO

Southern Idaho Eastern Oregon Corrosion Committee, Inc.
Is Proud to Present

The 59th ANNUAL SIEO / AMPP INTERMOUNTAIN WINTER SYMPOSIUM
To be held JANUARY 7th – 9th, 2026

The SIEO committee was organized over 60 years ago by corrosion technicians from several pipeline companies to discuss interference issues and mitigation with each other as well as sharing cathodic protection ideas in the expanding industry. The Winter Symposium was established by the SIEO as a forum for information and training for those involved, engaged, or interested in corrosion control in the Intermountain Region. This event will be held at Boise Centre on the Grove this upcoming January.  The atmosphere is very relaxed and casual dress is preferred. Attendance every year consists of approximately 100 corrosion technicians, engineers, pipeline personnel, state and federal inspectors, vendors, retirees, and friends. The Symposium will host approximately 10-12 in depth professional presentations concerning corrosion within our utility network.
