ADDITIONAL COMMENTS
On January 19, 2018, John Patrone met with Steve Cockman and Nick Kranz to conduct a comprehensive inspection of
the McGill Environmental Systems of North Carolina, Inc. – Merry Oaks Large Type 4 SWC Facility on Christian Chapel
Church Road in New Hill, Chatham County.

1. The facility is a Large Type 4 Solid Waste Compost (SWC) Facility. It produces compost from industrial and
municipal residuals and sludges, grease trap waste, and food and agribusiness wastes and from a variety of bulking
agents: wood ash, yard waste, wood mulch, tobacco waste, sawdust, etc. (see Operations Plan pg 13) and
additional materials as approved by the Solid Waste Section (SWS).
2. Material is received from counties within North Carolina and from Virginia.
3. The facility is in operation Monday through Friday 8:00 am to 5:00 pm and Saturday 8:00 am to noon.
4. The facility permit, site plan, and operations plan were discussed.
5. Compost is sold in bulk to landscape supply businesses, grading companies, and to the agribusiness community.
6. The facility building is ~ 112,500 ft2.
7. Composting is conducted within the facility building. Feedstocks are off-loaded into a pit at the south end of the
building. High carbon bulking material, stored outside, is brought into the pit through a side door. The feedstocks
and bulking materials are mixed together. The mixed material is stockpiled within the pit area until enough is
available to fill an active compost bay.
8. The mixed material is placed in positive aeration bays to meet process to further reduce pathogens (PFRP). Each
active compost bay is enclosed on three sides and has a reinforced polyethylene laminate tarp that remains in-
place across the open portion of the bay.
9. When the material has met PFRP it is screened by a dedicated screener located within the building and placed in
bays to meet vector attraction reduction (VAR).
10. Material removed from the active compost bays, that is awaiting VAR and has not been screened, is stockpiled
in an open area of the building (individual bays have not been constructed). The area also contains the dedicated
screener and an additional VAR bay.
11. Mr. Cockman stated that ~ 50 percent of the material that has met VAR is returned to the active compost process
(as a cover layer) and to the mixing and bulking pit (to include overs from the screening process) to aid in attaining
PFRP.
12. Material is considered cured after meeting VAR. Cured product is screened by a dedicated screener. The screener
and feed-hopper are located within the building at the north end. The screened material deposits outside of the
building onto a concrete pad.
13. At certain times of the year material that has met VAR and has not been screened is stockpiled outside in
operational areas until screened.
14. Screened compost is considered finished product. Finished product is stockpiled outside and commonly sold at
a dedicated storage area.
15. The facility has 10 individual active compost bays (Nos. 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19) and a triple-wide
bay/curing area (constituting what would be bay Nos. 21, 23, and 25) and an additional curing bay – No. 20.
16. Each bay has a positive aeration fan (three fans in the triple-wide bay curing area).
17. An active compost bay is constructed with a layer of wood chip, seven feet of mixed material to be composted,
and one foot of material that has met VAR along the front of the pile, facing the open end of the bay.
18. A front end loader combines materials in the mixing and bulking pit and transfers it to the active compost bays.
When material has met PFRP, a second front end loader transfers it to be screened and places it in curing bays to
meet VAR. When material has met VAR, a third front end loader transfers it to be screened and manages the
compost on site.
The item(s) listed above were observed by Section staff and require action on behalf of the facility in order to come into or maintain compliance
with the Statutes, Rules, and/or other regulatory requirements applicable to this facility. Be advised that pursuant to N.C.G.S. 130A-22, an
administrative penalty of up to $15,000 per day may be assessed for each violation of the Solid Waste Laws, Regulations, Conditions of a Permit,
or Order under Article 9 of Chapter 130A of the N.C. General Statutes. Further, the facility and/or all responsible parties may also be subject to
enforcement actions including penalties, injunction from operation of a solid waste management facility or a solid waste collection service and any
such further relief as may be necessary to achieve compliance with the North Carolina Solid Waste Management Act and Rules.

19. Mr. Cockman stated that each front end loader is dedicated to a prescribed operation and that if secondary use is
required the front end loader’s bucket will be decontaminated.
20. The mixing and bulking pit and the active compost bays exhaust fans route to a biofilter [unit] located outside,
adjacent to the building.
21. There are five biofilters. The biofilters are constructed atop a pad consisting of soil-cement [clay, fly ash, lime,
and concrete].
22. The biofilters consist of a layer of wood chip, perforated pipe, a layer of compost, and a second layer of wood
chip.
23. Mr. Cockman stated that the biofilter media was replaced in September 2015.
24. A maintenance pathway (an area that does not contain filter media) abuts each biofilter. Each biofilter is ~ 37’
wide and 3’ high. Each maintenance pathway is ~ 30’ wide.
25. Active compost bay groups Nos.: 1, 3 and 5, Nos.: 7 and 9, Nos.: 11 and 13, and Nos.: 15, 17, and 19 each
exhausts through a manifold to one of four biofilters and the mixing and bulking pit exhausts to a dedicated
biofilter. The VAR bays do not exhaust to a biofilter.
26. Mr. Cockman stated that a replacement biofilter will be constructed adjacent to the biofilter [unit] in ~ July 2018.
It will serve active compost bays Nos.: 15, 17, and 19. The current biofilter serving those active compost bays
will be removed and the material composted.
27. There is a total of 19 fans serving the compost process: 14 positive aeration and 5 negative aeration (mixing and
bulking pit, PFRP, and VAR).
28. The facility has three positive aeration fans serving the material that has met PFRP screening process (prior to
VAR) and the adjacent open area. The open area constitutes what would be the even numbered bays.
29. High carbon nitrogen ratio bulking material is stored outside behind the building. Clean wood and yard waste is
ground ~ every 4 to 6 weeks. A portable grinder is brought on site to grind the material. Mr. Cockman stated
that there is ~ 2,500 tons of bulking material on site.
30. Stockpiling of high carbon ratio feedstocks and finished product shall be limited to 50’ in width x 30’ in height.
31. Sludge is off-loaded directly into the mixing and bulking pit.
32. The facility has a 120,000-gallon sludge aboveground storage tank (AST). Mr. Cockman stated that absorbent
material is on-hand in case of a leak and that bagged sand and hydrated lime is kept in a shipping container stored
on site.
33. The facility no longer pumps sludge into the AST, it only removes it. It is estimated that there is 5 thousand
gallons of sludge in the AST and that it will be empty in ~ 2 years. At that time, the AST will no longer be used.
34. Mr. Cockman stated that an effort will be made to ensure the sludge from the AST is being continually introduced
into the compost process.
35. A vehicle scale test was conducted by the North Carolina Department of Agriculture & Consumer Services on
May 30, 2017 – approved.
36. A vehicle scale repair and test was conducted by Central Carolina Scale, Inc. on March 2, 2017.
37. The facility maintains throughput records. The amount and type of material received was observed for 2017. The
facility received 72,108.22 tons of feedstocks and bulking materials. The amount of compost created and sold is
33,716.06 tons. Mr. Cockman stated that there is ~ 3,200 yd3 of overs and unscreened compost on site.
38. The amount of finished compost on site as of January 19, 2018 is 10,100 yd3.
39. The facility annual report (FAR) was received by the SWS dated July 19, 2017. Facility throughput for July 2016
through June 2017 is 93,715.17 tons. The amount of compost produced is 38,029.89 tons. The amount sold and
given away is 38,029.89 tons.
40. The facility produces Grade A compost. An information pamphlet is provided for customers in the office and on-
line material is available at the facility website: www.mcgillcompost.com. The customer product manifest has a
caution note for proper use.
41. The facility uses a program from the University of Maine to monitor bulk density, C:N ratio, and moisture content.
Moisture content is verified by hand.
42. Compost bay temperature records for PFRP and VAR were observed for 2017.
43. Temperature probe calibration records were observed for December 2017. Four manual temperature probes are
calibrated then compared to 18 active compost bay electronic temperature probes.
