Welcome to the Olin CEOP enrollment website for LCAAP employees! Log in now to make your elections!

Employees transferring from the Lake City Army Ammunition Plant (LCAAP) to Olin Winchester, LLC have the option to elect how much they  would like to save and how their Plan account will be invested once they become eligible for the Olin CEOP on October 1, 2020. This is a secure website, separate from the Olin CEOP website maintained by Voya, the recordkeeper for the Olin CEOP.

The information you provide will be used solely for the purpose of enrolling you in the Olin CEOP. Employees should read all Olin benefit-related information prior to making elections on this website.

Call a Voya Customer Service Associate at 1-888-865-OLIN (1-888-865-6546) weekdays from 8 a.m. to 8 p.m., ET, excluding stock market holidays. The Customer Service Center is open for general plan inquires or if you need help with this website. 

Once Olin Winchester, LLC assumes the operation and management of the Lake City Army Ammunition Plant on October 1, 2020, a Customer Service Associate will be able to answer specific questions about your Plan account and assist with transactions.
