permit.
If any parts, measurement frequencies or sampling requirements contained in this general permit
are unacceptable to you, you have the right to submit an individual permit application and letter requesting
coverage under an individual permit. Unless such demand is made, this decision shall be final and
binding. Please take notice this permit is not transferable. Part II, EA. addresses the requirements to be
followed in case of change of ownership or control of this discharge.
The Authorization to Construct is issued in accordance with Part III, Paragraph 2 of NPDES
Permit No. NCG510000, and shall be subject to revocation unless the wastewater treatment facilities are
constructed in accordance with the conditions and limitations specified in Permit No. NCG510000.
