EPA issued an Administrative Order for Access (First Order) to the Respondent on 9/7/2001, regarding Respondent's property located at the Rocky Flats Industrial Park. EPA has determined it is necessary to issue this supplemental order to restrict Respondent's access to a portion of the Property to prevent interference with implementation of the removal action authorized by the 9/25/2000 Action Memorandum for the AERRCO/Thoro properties at the Rocky Flats Industrial Park site and all response actions taken and to be taken in furtherance of the removal action.
