Beneficiation Stormwater Permits
Proposal of General Permit No. NCG140000
July 24, 2018
Coal ash, specifically, fly ash is a major component of the concrete batch plant process
DUKE
ENERGY.
`A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that
combines various ingredients to form concrete. Some of these inputs include water,
air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement. There are two main types
of concrete plants: Dry mix plants and Wet mix plants, and also plants that contain both a transit mix side and a
central mix side while utilizing common material storage points. A concrete plant can have a variety of parts and
accessories, including: mixers (either tilt drum or horizontal or in some cases both), cement batchers, aggregate
batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant
controls, and dust collectors".

BENEFICIATION FACILITY DESIGN (Buck, Cape Fear, and HF Lee)
Best Management Practices:
i Construct roads without ditches, allowing for sheet flow and preventing concentrated flow.
Reducing impact to streams and wetlands
Closed loop, water recycle system
"''� Multiple t k wash systems: 1.) trucks leaving ash basin will exit through a wheel wash station,
oaded trucks leaving the STAR units will exit facility through a truck rinse
Sealed Loading System: product is loaded utilizing a sealed system with evacuated air filtered,
preventing dusting and product loss.
Product is handled in focused and controlled areas: loading in the ash basin for delivery to the
facility, product storage in an enclosed dome, and loadout to trucks from the dome using a
sealed system
TIMELINE
Buck will begin testing in 3rd quarter 2019.

Renewal Obtained
Footnotes:
I Maintain quarterly monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, th.e permittee must submit a monitoring report .
indicating "No,Flow" or "No Discharge" within 30 days of the end of the sampling period.
Failure to monitor per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall
during a monitoring period does not constitute failure to monitor, as -long as it is properly
recorded and reported.
The current NPDES Wastewater Permit NC0005363 requires the facility to conduct fish
tissue monitoring once during that permit term for arsenic (As), seleniuin (Se), and
mercury (Hg) in accordance with a Sampling Plan approved by the Division of Water
Resources. The permittee shall submit a copy'of fish tissue monitoHbg results to'the
DEMLR Stormwater Permitting Pro ra {Central Office) within 30 da s of r eivin result
72 in icate t e location of sampling in relation to stormwater discharge outfalls. This Ir '
reporting timeframe differs from the NPDES Wastewater Permit, which directs that fish
tissue analysis results be submitted with the wastewater discharge permit renewal
application.
The permittee shall compare monitoring results to the benchmark values.in Table 3.
Exceedances of benchmark values require the permittee to increase monitoring, increase •,
management actions, increase record keeping, and/or install stormwater Best Management
Practices (BMPs) in a tiered program. See the descriptions of Tier One, Tier Two, and Tier
Three response actions below. In the event that the'Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three, the Division's
release letter may remain in effect through'sblisequent reissuance' of this permit, unless the _ L-
release letter provides for'other conditions or duration.

Bridget,
Mike has the Buck permit. He will respond to you, but I am not sure if they need a permit from NPDES. My
understanding is that there will be no separate discharge of wastewater from recycling program.
