TABLE OF CONTENTS

Item 8.01. Other Events

     On November 29, 2004, Pioneer Americas LLC, a subsidiary of the registrant, notified customers served by Pioneer Americas’ chlor-alkali plant in St. Gabriel, Louisiana that the plant had been restored to a full operating rate and that we had not found it necessary to allocate product deliveries to our contract customers.

     As reported in a current report on Form 8-K that we filed on November 22, 2004, we had notified our customers that the plant’s operating rate had been reduced in order to continue to meet emissions permit requirements. We had anticipated that the necessary delivery and installation of materials used in our emission control equipment could cause us to maintain a reduced operating rate until the end of November, with a resulting inability to supply all of our customers’ needs.

     Due to the efforts by our plant personnel, we were able to complete the project and restore the plant’s full operating rate on Thanksgiving Day. As a result we did not reduce deliveries to any of our customers.
