Inspection Summary:
Facility Description:
Martin Marietta Aggregates, a Division of Martin Marietta Materials, operates the Mallard Creek Quarry for the purpose of
producing crushed aggregate for use in the construction industry. The quarry is located at 575 E. Mallard Creek Church
Road in Charlotte, North Carolina,
Compliance History:
Charlotte -Mecklenburg Storm Water Services personnel responded to a discharge from the Martin Marietta Mallard Creek
Quarry on December 22, 2004. A Notice of Violation was not issued for the discharge.
The permitteelfacility does not have any prior compliance issues with the NC Division of Water Quality.
Industrial Operations/City of Charlotte Stormwater Ordinance Review:
Quarry/Pit Sump —
All discharges at the site are either stormwater discharges or a combination of groundwater seepage and stormwater
runoff. Groundwater seepage collects in the pit sump prior to being discharged. The sump also collects the majority of
the stormwater runoff. All other discharges at the site are the result of stormwater runoff. Pit dewatering is a typical
quarry activity and is authorized under the NPDES permit. The implementation of diversion ditches, rock check dams,
and sediment basins are used to manage stormwater runoff at the site. Pit expansion is to be conducted in a manner so
as to divert all stormwater runoff from disturbed areas to the pit, which allows sediment to settle out prior to discharging.
Detention Pond —
The detention pond at the site is used to collect runoff from the aggregate wash area. The water in the detention pond is
recycled at the facility. Therefore, there is no discharge from the detention pond.
Storage Tank Area -
There are several aboveground storage tanks (ASTs) located at the facility; there are no records of any underground
storage tanks (USTs) at the site. The ASTs contain petroleum products used to service mobile and plant equipment. The
tanks included a 6,000-gallon diesel AST, a 530-gallon gasoline AST, a 1,000-gallon bulk oil AST, a 2,000-gallon bulk oil
AST, and a 500-gallon waste oil tank. In addition to the ASTs, there are also several 55-gallon bulk oil drums located in
the storage tank area. Secondary containment was provided for all of the ASTs and drums, except a small waste oil
container.
The waste oil container should be moved into the secondary containment area in case there is a spill.
