modification is issued pursuant to the requirements of North Carolina General Statutes 143-215.1 and the
Memorandum of Agreement between North Carolina and the U. S. Environmental Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the office of Administrative Hearings,
