Senate committee substitute makes the following changes to 3rd edition. Adds a Part II to authorize the expedited cleanup of storm-related debris. Allows the disposal, temporary storage, and burning of storm-related debris from the date that the state of emergency was declared by the Governor under Executive Order No. 87 through June 1, 2011 in spite of any state laws regarding permitting requirements for handling or disposing of solid waste, or prohibitions on open burning related to protecting air quality. Provides that the provisions allowing the cleanup of storm-related debris are not to be construed as (1) allowing the improper or unpermitted storage, disposal, or burning of hazardous waste; (2) removing the need for a burn permit as required under Article 4C of GS Chapter 113 , (3) allowing any activity that violates federal law, and (4) allowing any activity that causes an imminent threat to public health or safety. Makes a conforming change to the title to reflect the additional bill content.
