Directions to the facility are as follows: Take US-74/76 West from Wilmington toward Lumberton/Whiteville for
6.3 miles to the P Leland exit (Mt. Misery Rd. / Lanvale Rd.) At the stop sign at the exit ramp, turn left onto
Lanvale Road. Follow Lanvale Rd. for 0.3 miles and then turn right onto Fletcher Road. The concrete plant is
located 0.5 miles down on the left just past the Highland Paving asphalt plant.

1. Contact was made at the plant site with Manfred Alligood, Owner, to conduct a compliance
assurance visit. Manfred can be reached by cell at [phone]. The plant telephone is
[phone].
2. ABHW Concrete III, operates a new concrete batch plant(truck mix)rated at 100 cubic yards
per hour maximum at this location that consists of one split storage silo (50% cement, 50%
flyash),and one weigh hopper. A ground level central dust collector is installed on all sources.
This appears to be a good quality dust collector. Mr. Alligood previously indicated it came
with a cost of over$50,000.
3. On February 19, 2021, ABHW Concrete III, LLC requested a permit applicability
determination for this new concrete batch plant. Based on their letter and information
provided, DAQ determined on March 3, 2021 that an Air Quality Permit is not required
because the actual emissions of each criteria pollutant is less than 5 tons per year,the aggregate
actual emissions of all criteria pollutants are less than 10 tons per year, and per 15A NCAC
2Q .0102(d), any facility whose actual emissions of particulate matter (PM10), 5O2, NOx,
VOC's, CO, HAP's, and TAP's are each less than 5 tons per year and whose actual total
aggregate emissions are less than 10 tons per year shall not be required to obtain a permit
pursuant to 15A NCAC 02Q .3000.
4. Minimal fugitive dust emissions were observed from the plant grounds during the inspection.
The facility uses a sprinkler on the property to keep fugitive emissions to a minimum. Some
of the property is paved with concrete. The facility plans to pave more parts of the property
as business grows. This plant is in a commercial area and well back off the road with no
nearby surrounding private residences. The facility recently paved about 50 feet of concrete
at the plant entrance to help with fugitives.
5. The facility is currently operating five (5) or six (6) days per week, fifty-two (52) weeks per
year. The current loading rate for the site is approximately two hundred and fifty (250) yards
of concrete per day. ABHW Concrete currently runs ten(10)trucks out of this site.
6. ABHW Concrete started producing concrete at this location in June of last year. ABHW
Concrete has two other plant locations in North Carolina. The first plant was put in
Washington many years ago. Another plant was recently put in New Bern a few years ago.
This is a family business operated by a father (Manfred—Leland plant), son (Manfred, Jr. —
New Bem plant)and the son's wife (Lisa—Washington plant).
7. No cement or flyash silo loading was occurring during the inspection. This facility receives
approximately two (2) loads of cement per week and approximately two (2) loads of flyash
every month with an average process rate of twenty-five(25)tons per load per hour. Loading
time is usually one hour.
8. Cement and flyash are transferred from split silo to the weigh hopper as a conveyor transfers
sand and aggregates into a discharge area located below the weigh hopper. The discharge
area is equipped with a flexible boot(hose or chute)that transfers the ingredients into the truck
mixer. Fugitive dust emissions can be generated as sand and aggregates are conveyed from

storage into transit-mix trucks and as flyash and cement are transferred from silo to weigh
hopper into transit-mix trucks. Visible emissions can be excessive unless the loadout area is
equipped with a hooded or partial enclosure of some type with a vacuum point, which is the
case for this plant. The facility has installed an enclosure, which partially covers the truck
mixer when loading sand, aggregates, cement, and flyash. This enclosure appears to be well
designed and is equipped with four vacuum lines that are vented to the central dust collector.
This results in higher control efficiency for collecting the fugitive dust generated during truck
load-out activities. Mix trucks were observed being loading during the inspection with
minimal fugitive emissions.
9. This plant is fairly new and not even a year old, so currently requires very little maintenance.
In the future, maintenance will be performed on the baghouse on a regular basis and
maintenance records will be kept on site for reference. The baghouse is self-cleaning with jet
pulse air automatically occurring every three minutes. Plant personnel have begun logging a
daily magnahelic reading on the baghouse. A good pressure range appears to be 1.5 to 2
inches of water,which is what it was reading during the inspection. During the loading of the
silos, delivery pressure from the truck should be kept at a minimum to avoid bag failure.
ABHW Concrete III, LLC operates their trucks at a delivery pressure no greater than ten(10)
pounds per square inch. An increase in pressure above this limit could cause a bag failure.
10. A ground level central dust collector, as previously described, controls the particulate
emissions generated in this concrete plant batching process as follows:
• The emissions generated during cement and flyash silo loading.
• The emissions generated during the transfer of cement and flyash into the weigh hopper.
• The emissions generated during the transfer of sand,aggregates,cement and flyash from
the weigh hopper and conveyor discharge area into the mixer truck.
11. 5-Year compliance history — No NOD's, NOV's, or NRE's have been issued. This is the
second inspection and a fairly new facility.
12. ABHW Concrete III, LLC appeared to be operating in compliance with Air Quality rules
during the inspection.
