Subject: Authorization to Construct
Martin Marietta - Mallard Creek Settling Cell
ATC No. ACS020173
Mecklenburg County
Per your request, a review has been conducted of the request
for an ATC at the subject facility for the construction of two

Certificate of Coverage NCGO20173
General Permit NCG020000
Formerly NPDES Permit NCO065951
Mecklenburg County
The Division of Environmental Management has recently evaluated all existing individual permits for potential
coverage under general permits currently issued by the Division. 15A N.C.A.C. 2H .0127 allows the Division to
evaluate groups of permits having similar discharge activities for coverage under general permits and issue
coverage where the Division finds control of the discharges more appropriate in this manner. The Division has
determined that the subject discharge qualifies for such coverage. Therefore, the Division is hereby issuing the
subject Certificate of Coverage under the state-NPDES general permit no. NCGO20000 which shall void NPDES
Permit NC0065951. This Certificate of Coverage is issued pursuant to the requirements of North Carolina and the
US Environmental Protection Agency Memorandum of Agreement dated December 6,1983 and as subsequently
amended.
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, associated processing fee and letter requesting
coverage under an individual permit. Unless such demand is made, this decision shall be final and binding. Please
take notice this Certificate of Coverage is not transferable. Part II, EA. addresses the requirements to be followed
in case of change of ownership or control of this discharge.
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, the
Permittee shall take immediate corrective action, including those as may be required by this Division, such as the
construction of additional or replacement wastewater treatment or disposal facilities. Construction of any
wastewater treatment facilities will require issuance of an Authorization to Construct from this Division.
Failure to abide by the requirements contained in this Certificate of Coverage and respective general permit may
subject the Permittee to an enforcement action by the Division of Environmental Management in accordance with
North Carolina General Statute 143-215.6A to 143-215.6C. Please note that the general permit does require
monitoring in accordance with federal law. The monitoring data is required to be submitted to the Division no later
than January 31 for the previous year in which sampling was required to be performed.

Certificate -of Coverage No. NCG020173
The issuance of this Certificate of Coverage is an administrative action initiated by the Division of
Environmental Management and therefore, no fees are due at this time. In accordance with current rules, there
are no annual administrative and compliance monitoring fees for coverage under general permits. The only fee
you -will -be responsible for is a renewal fee at the time of renewal. The current permit expires August 31, 1997.
This,coverage will remain valid through the duration of the attached general permit. The Division will be
responsible for the reissuance of the general permit and at such time, you will be notified of the procedures to
follow -to continue coverage under the reissued permit. Unless you fail to follow the procedures for continued
coverage, you will continue to be permitted to discharge in accordance with the attached general permit.
The issuance of this Certificate of Coverage does not preclude the Permittee from complying with any and all
statutes, rules, regulations, or ordinances which may be required by the Division of Environmental Management
