SECTION 3.0
3.1
Please see Attachment A, Merry Oaks 2019 Intake Spreadsheet. All new feedstock customers provide
the required analytical data to McGill prior to McGill accepting their intake material. The provided data
is then provided to NC DEQ as requested in our permit.
3.2
Please see Attachment A, Merry Oaks 2019 Intake Spreadsheet. There are no significant seasonal
variations in feedstock with some exceptions such as yard waste which by its nature varies with the
seasons. The most significant variation is a higher portion of grass in the summer versus leaves in the
fall. We manage this by adjusting amendment usage.
3.3
Facility capacity (excluding woody amendments):
Number of primary bays = 10.
Bay residence time = 7 days.
Mass per bay = 200 tons.
Maximum bay cycles per year 52.
Total plant capacity: 10 bays x 52 cycles x 200 tons = 104,000 tons.

Recipes are developed with the objective to achieve both a moisture level of 55-60% and a C:N ratio of
at least 20:1. Mixing is performed by wheel loader. The greatest variable is moisture content of
amendments.
A typical mix might be as follows:
• 1 bucket of residuals or biosolids
• 2 buckets of overs
• 1 bucket of ground yard waste
The blending operator is also trained to use the "Squeeze Test" as well as visual inspection to monitor
moisture levels in the mix.
3.6
All mixing is performed by wheel loader. Materials of differing consistency are stored separately. Waste
material with high nitrogen and moisture content are stored in the pit area within the blending building.
Yard waste, is stored outside but near the blending area of the operations building. The separate storage
ensures the blending operator can accurately measure the correct portions for the recipe.
Grinding of feedstock is done on a regular scheduled basis. A portable grinder is contracted, and there is
a designated grinding area for the purpose of preparing yard waste, dimensional lumber, and pallets.
These feedstocks are stockpiled outdoors until needed. Wheel loaders are used to transport the ground
feedstock into the blending area for mixing. All oversized, woody material (overs) that is removed
during the screening process is returned to the blending area for use in future mixes.

McGill uses an aerated static pile composting process. The process works on a batch basis with each
batch being approximately 1,000 cubic yards. The primary processing area, consists of 10 bays, and each
is a self-contained unit with its own aeration fan, ducting, and air distribution network embedded in the
floor (patented). Each bay is independently monitored and controlled.
Below are the steps utilized:
1. A 3-inch layer (approximately) of clean wood chips (or other dry material) is placed on top of the
aeration channels to facilitate even air distribution throughout the composting mass, absorb
excess moisture, and prevent clogging of the aeration pipes.
2. The blended mixture is placed by front-end loader on top of the wood chips to a height of nine
feet. The pile is constructed from back to front. When the pile is about one-half complete, the
operator places a sensor in the middle of the batch with the tip about four feet deep.
3. A layer of compost is placed over the end of the pile as a cap in order to insulate the material and
improve heat retention and contribute to the overall tidiness and cleanliness of the process area.
4. The bay is filled, and the operator notifies the supervisor to start the bay on the control panel.
This initiates the electronic temperature monitoring. The bay number and start date make up the
batch number.
Compost pile construction
The bay temperature probe and supply fan are connected to a centralized processor which monitors and
records temperatures. The processor has a proprietary software program that continuously adjusts air
flow to insure optimum temperatures and maintain aerobic conditions at all times. Throughout the day,
the plant manager will check the data records to verify operating status and troubleshoot, as needed.
The system is randomly verified with a hand-held probe. The system is also monitored remotely
through cell phones.
3.10
Not applicable as all composting activities are carried out indoors.
3.11
All composting activities are carried out indoors. Any water that comes into contact with the final
compost product and is not absorbed has been permitted to combine with stormwater and be directed
towards one of the stormwater basins onsite prior to being discharged from the site.
3.12
A small number of customers require sand to be added to the final product prior to distribution. No
other amendments such as wood ash, lime, or gypsum are added to the final compost product.
3.13
Several steps are taken to avoid the buildup of dust:
• Dusty amendments are off loaded inside the blending building
• Batches are thoroughly mixed to ensure sufficient moisture at the beginning of the process
• Misting systems are used at both screening plants to both prevent and suppress dust
• Loaders are washed down at the end of each shift
• Heavy traffic areas are sprayed with water on an as -needed basis
Air from inside the processing and curing bays is pulled from the top of the bays through a piping system
and forced through a biofilter prior to being released into the environment to curb any other potential
air emissions.
3.14
Overs material (large woody pieces) from both screening plants is returned to the blending area for
reuse. This process is continued until the overs gradually break down. No recycling of "recyclable
products" or other types of material handling is conducted at this facility.

4.2
Scale: The scale is a GSE scale, model 460.
Structures: The operations building is a 112,000 sq/ft building. All floors are constructed of reinforced
concrete. Functionally the building is divided into the blending area, primary processing, primary
screening, curing, final screening, and product storage. The walls are also reinforced concrete to a
minimum height of 10'. The structure is a standard industrial metal building, and steel components are
corrosion protected where required. The 10 primary processing bays (within the main building) have
concrete walls to a minimum height of 16'.
Unloading area: All waste materials are unloaded into the blending area from an outside offloading
ramp. The ramp is constructed of reinforced concrete and is sloped into the blending area.
Biofilter Odor Control System: In addition to odor prevention practices, the biofilter remains the main
method of odor control.
Water Source: Water for the facility operation is from an onsite water well.
Wheel loaders: Loaders with both 6.5 and 9.0 cubic yard buckets are used for blending materials, filling
and emptying bays, loading compost into trailers, and moving compost and amendment materials.
Liwell screen: The Liwell screen is used to remove overs from compost.
Trommel screen: The Trommel screen is used to remove overs from compost.
Bobcat skid steer: The Bobcat has both a bucket and a power sweeper. It is used to move materials,
and the sweeper is used to clean bays after they are emptied.
Equipment Maintenance
All equipment maintenance is performed on a scheduled basis as dictated by the manufacturer's
recommendations.
Wheel Loaders: All major servicing is performed under a service contract with the
supplier/dealer every 250 hours and includes all fluid changes. Daily greasing, fluids inspection
and cleaning are performed by the operator. Greasing and fluids check is always as per
manufacturers specifications.
2. Fans: Fans are inspected daily. This involves a visual inspection by the manager or maintenance
technician. Fans are greased as per manufacturer specifications.
Screening Plant: Daily servicing is performed by a maintenance technician or operator. This
involves greasing, tracking belts, cleaning pulleys, and visual inspection. Any larger maintenance
or repair may be performed by qualified outside vendors. Both screening plants are stationary
electric which greatly reduces the maintenance load.
4.3
The facility consists of approximate ly50 acres, of which approximately9 acres are utilized for all
activities. The site has one road used to access and exit the site and is located on the southern border
of the property. There is a locked gate across the site access road and fences are located at various
places around the perimeter of the property. The facility is surrounded by dense woodlands on all
sides, and vegetated berms are located around the perimeter of the operations area. The facility is also
protected by security cameras at various locations around the facility.
The facility is not open to the general public for either feedstock drop off or product sales.
4.4
A McGill employee is onsite at all times while the gate is unlocked.
4.5
The access road is constructed with all-weather materials, and the road is maintained.
4.6
The facility is open to accept materials from contracted customers from 6:30 am to 5:00 pm Monday
through Friday and from 7 a.m. to 12 p.m. on most Saturdays. During busy times, the plant personnel
may have extended hours. The following are general guidelines for plant employees:
1. At the beginning of each workday, employees meet with the plant manager to go over the
rotation of bay schedule, issues still outstanding, and plans for the day.
2. Following the meeting, plant employees go to their assigned area within the plant and inspect
their equipment (screens, loaders, etc.) prior to start up.
3. Employees perform their daily tasks as assigned whether it is blending feedstock, moving curing
materials from one bay to another, repairing equipment, or cleaning bays after use.
4. When the scale office closes, the gate at the entrance is locked.
4.7
Posted at the entrance of the facility are signs that list the types of PPE required, emergency contact
phone numbers, permit number, types of waste received, types of waste not accepted, and operating
hours. Listed as the types of waste not accepted are hazardous waste, asbestos containing waste, and
medical waste.
4.8
Densely wooded areas surround the facility on all sides.
4.9
The following positions are typically staffed for proper operation of the facility.
Plant Manager: Responsible for all day-to-day activities at the facility including production,
administration, process control, monitoring and record -keeping, transportation, compliance,
invoicing, and human resources (including training). This individual represents McGill at local
civic and business functions and is responsible for business development and customer service
for the facility. This individual is the direct supervisor of the plant superintendent, dispatcher,
drivers, and contract administrator.
2. Team Lead: Responsible for through -put at the plant is the first line supervisor for all processing
employees. Responsibilities include proper handling and storage of raw materials including
monitoring of all incoming loads to verify documents and material integrity, blending ratios and
blend quality, primary processing, screening, curing, and finished product blending and loading.
This individual is also the direct supervisor of all processing plant employees.
3. Industrial Mechanic: Responsible for routine maintenance, repair, replacement of
motor/blower units, transport vehicles, blending and screening units, loaders, tools, and other
equipment; painting and minor structural repairs.
4. Loader Operator: Responsible for the control of blending rates of raw materials to assure a
proper mixture according to prescribed ratios, placing blended mixture to composting bays,
placing and removing temperature sensors, cleaning aeration channels, operating loaders,
screening plant, moving fresh compost to screening and curing, blending market products,
loading outbound transport vehicles, scraping the yard, leachate management and collection,
daily equipment inspection and maintenance.
5. Dispatcher: Responsible for scheduling and monitoring McGill and contractor vehicles in and
out of the facility, scheduling and training driver, scheduling vehicle repair and maintenance,
mobilization of equipment, D.O.T. compliance and insurance verification, weigh master.
4.10
Training records, including names of attendees, information covered, trainer, and examples of any
training materials/handouts are to be maintained for a period of five years. The following records are
kept:
1. All Employees: Orientation, including company overview, personnel policies, health and safety
overview.
2. Drivers: Defensive driving, personal safety, drug and alcohol testing, accident response, road
hazards, and hours of service.
3. Operational Employees: Equipment operation and maintenance, compost pile construction and
breakdown, and quality assurance.
McGill plant managers meet the personnel requirements described in Rule .1406 (19)(a). The
operational employees meet the requirements described in Rule .1406 (19)(b) and (c).
4.11
Only pre -approved materials are accepted at the facility and may be transported to the facility by
McGill, customers, or contract haulers using vehicles and containers appropriate to the feedstock type.
Once the driver arrives onsite, the truck is pulled onto the scale. Paperwork is generated with the
customer's name, date, truck number, and weight of feedstock. Depending on the type of incoming
feedstock, the driver either unloads into the pit of the operations building (biosolids, grease trap waste,
food, etc.), or the driver unloads the trailer on the west side of the operations building if the incoming is
an amendment such as yard waste or untreated wood. Prior to leaving the site, each driver that has
unloaded into the pit is required to rinse out the trailer and let the rinsate drain into the pit.
A McGill employee will blend the materials in the pit with amendments using a dedicated loader. This
prevents biosolid material from being tracked throughout the operations building. Following the mixing
process, the mixture is put into processing bays. This is referred to as the primary processing step. The
mixture remains here for 7 days. The continuous aeration system insures optimum biological activity
and that temperatures remain above PFRP requirements. This temperature is measured with an
electronic probe, and all temperature readings are recorded and stored in a data software system.
Following the primary step, the material is removed and screened through the primary screen. The
oversized material (overs) is returned to the blending area for future reuse. The screened material is
placed in a curing bay where temperatures are again monitored. The curing bays have identical controls
to the primary bays. Again, the material is subjected to continuous aeration which allows optimum
temperatures to be maintained. VAR is achieved and recorded during this phase. At the end of this
phase the compost is eligible for sale; however, the vast majority of the cured material goes through a
final screening process. The objectives here are commercial, and a finer product is more valuable to the
typical McGill customer. As with the primary screening process, the overs from the final screening are
returned to the blending area for future reuse. The screened product is moved to the compost storage
area.
Product is typically sold by volume, so loader bucket counts are used when loading product. Paperwork
is generated documenting the truck, where the compost is going, date, etc. Following the completion of
the loading, the truck drives onto the onsite scale where it is measured, and the weight of the truck is
noted on the paperwork.
The blending, primary processing, curing and screening steps all take place within the operations
building as discussed in previous sections of this application. Finished product is stored on the northern
side of the operations building. At the beginning of each month, the finished compost is sampled and
sent to a certified laboratory to analyze for constituents and properties required by the U.S. Compost
Council. Twice a year a sample is collected and sent to a certified laboratory for the analysis of TCLP.
The time needed in each of the processes is referenced in Section 3.0, Part 8.
4.12
Only pre -approved materials may be accepted at the facility. A McGill representative visits the waste
generator prior to approval in order to have a full understanding of the waste. Extensive pre -acceptance
analyses are required for feedstock. As an additional measure, McGill has a clause in its contracts with
customers that requires the customer to remove any load that is deemed by McGill as not meeting the
agreed -upon, permit -required standards. A McGill employee follows up with the customer regarding
the issue. No unacceptable waste is accepted, stored, or disposed of by McGill. The fact that most
incoming material is brought to the facility by a McGill employee operated truck or McGill contractor
adds another layer of oversight.
4.13
The majority of residuals accepted at the facility have some odor potential, so all are handled in a very
controlled manner. All residuals are offloaded into the blending section of the operations building and
liquids are kept separate from solid material. This is done to accommodate better management of
liquids. Getting incoming residuals properly mixed and on air is an ongoing priority at the Merry Oaks
facility.
4.14
Yard waste and clean, shredded wood are the primary amendments introduced to the process on an
ongoing basis. These amendments are stored on the northern portion of the operations area of the
property. A loader takes the necessary amount to the blending area, and the amendments are mixed in
with the other feedstock in the blending area. No wood ash is added as an amendment. The only other
major amendment are the overs from the screening operations.
4.15
The only processing activity that is needed to prepare materials for composting is grinding of wood
waste and yard waste. This is done on a scheduled basis by a third -party contractor who performs the
work at the McGill facility.
4.16
McGill uses a static pile positive aeration process so no windrows are built.

The average sizes of the piles are listed above. Between individual piles and between piles and the
vegetated berms onsite, a distance of at least 20 feet is maintained in order to have access for fire-
fighting vehicles.
4.17
McGill complies with Rule .1406 (11), (12) and (13) regarding time and temperature. Temperatures are
monitored and recorded continuously. Each bay, primary and processing, has a dedicated probe which is
wired to the central control system where temperature and time are recorded. Probes are placed at the
center of each batch. PFRP temperatures are met during the primary phase. Though not required, PFRP
is achieved again during the curing phase. VAR temperatures are met and recorded during the curing
phase.
4.18
McGill uses probes that record the temperatures of the piles daily, and the temperatures are
automatically recorded into the computer software program used. The probes are calibrated at least
once per year and documentation is kept in the plant manager's office. The calibration method includes
using a real temp probe that is calibrated per manufacturer's specifications and then compared to the
reading of the probe after both probes are placed in a bucket of water.
4.19
Moisture of the product within the primary and curing bays is measured at least weekly using the oven
drying method. Those readings are recorded by the plant manager.
4.20
All bays, both primary and processing, have an individual and identical, 7.5 horsepower fan. Air is
supplied to the bays on a continuous basis. All fans are connected to an individual Variable Frequency
Drive (VFD). This allows a wide range of air flow. Throughout the composting process, primary and
curing, temperature data is being fed to a central processor. The airflow from the fan is adjusted on a
continuous basis based on established criteria of the needs of the composting material.
4.21
McGill Environmental Systems participates in the U.S. Composting Council's Seal of Testing Assurance
(STA) program. Finished product samples are sent to lab for analysis per permit requirements. Under
the STA program, additional analyses including bulk density, salts, germination, nutrients, and
micronutrients are performed. Finished compost samples are taken from stockpiles of product by an
employee trained in the sampling procedure. The employee wears dedicated, nitrile gloves to collect
the samples, and those gloves are discarded after the sampling is complete. The STA program requires
the following sampling protocols:
1. Logs, sampling diagrams, and Chain of Custody documents should be prepared (as directed by
the Plant Manager).
2. Avoid excessively moist compost. If balls form during mixing of composite materials, the
compost is too wet.
3. Use sterile stainless steel, plastic, glass, or Teflon containers and implements for collecting and
mixing samples. Between samples, clean collection tools and containers with soapy water, well -
rinsed and dried.
4. Collect samples from no fewer than 15 sample points, randomly selected and visually
representative of the material to be distributed. Total number of samples should be sufficient
to collect 1 g of material for every 1000 kg of compost (aliquot).
5. Each sampling point shall be at a depth of two to six feet into the pile from the outside surface
of the pile. Samples should be of equal size, at least 1000 cubic centimeters (about 1 quart)
each.
6. Place quickly in container(s) with minimal stirring. Mix and split samples under sheltered
conditions to reduce exposure to wind, temperature, sunlight, and precipitation.
7. Prepare for shipping a composite sample of no less than 1000 cubic centimeters; chill and ship
to the laboratory within 24 hours.
Any sample collected for testing for pathogens and nutrients shall be a representative composite sample
of the compost and shall be processed within a period of time required by the testing procedure.
4.22
Compost is delivered to customers through McGill drivers, customer's drivers, or contract drivers. The
compost is primarily used on general landscaping, construction, and sports turf.
4.23
All product is sold in bulk. Typical load sizes are 40-50 cubic yards. McGill is fortunate in that it has built
up a strong market for its products over the past 17 years and sells all its production; however, if
compost could not be sold due to a change in market conditions, McGill would re-engage with the
agricultural market.
4.24
The Plant Manager is responsible for collecting, filing, and distributing all records associated with facility
operation. These records are either stored on McGill's computer server, within the proprietary software
cloud, or in paper format in the plant manager's office. The annual report for the period July 1 to June
30 is submitted to the Division of Solid Waste by August of each year and contains the required
information. An example of the temperature log form for PFRP and VAR requirements is included in
Attachment D.
4.25
No process water is generated as part of the composting procedures. Stormwater basins are located
around the operational area of the facility. Those basins along with other stormwater best management
practices are regulated and inspected under McGill's Stormwater Pollution Prevention Plan and under
Permit NCG240005.
4.26
McGill has attained the necessary fire prevention permits from the Chatham County Fire Marshall and
undergoes periodic inspections related to the permits.
4.27
McGill employees are trained annually regarding the OSHA required Emergency Action Plan and Fire
Prevention Plan. Employees also undergo annual training for how to properly put out a fire using a fire
extinguisher. The fire extinguisher training is conducted by a third party.
Employees have been trained to either put the fire out using a fire extinguisher or the onsite water
wagon and hose. If the fire cannot be safely extinguished by an employee, the fire department will be
called. Any fire at the facility will be reported to the Solid Waste Section within 24 hours, and a written
notification of the details of the fire will be provided within 15 days of the incident.
4.28
As part of the Stormwater Pollution Prevention Plan training, employees are taught good housekeeping
skills which play into all aspects of keeping the facility sanitary. Vector control is achieved by using
electronic vector control devices placed throughout the facility. Dust is periodically blown off of
equipment and tops of walls within the operational building using compressed air. Throughout the
operational area outside of the operational building, water is used for dust suppression as needed.
At the end of each day, the concrete pad where the trucks unload feedstock into the pit is cleared and
any remnants of sludge or other feedstock is washed into the pit using a hose. All feedstock are either
mixed with amendments and put into processing bays by the end of the day or are properly stored in
the pit.
Having the composting process carried out indoors helps maintain sanitary conditions and good vector
control.
4.29
Since McGill's composting process is contained inside of a building, it is relatively weather -independent.
Historically only significant weather events that resulted in road closures have impacted the facility. On
those occasions, the facility closed until the roads cleared.
All screening is done with stationary electric equipment which have far greater reliability than portable
diesel units. A sizable inventory of spare parts is kept for each unit. The aeration fans are very reliable
and require low maintenance.
McGill leases all its wheel loaders. While in service all machines are under warranty and comprehensive
service agreement. McGill's policy is to have no loaders that are greater than 3 years old and the mean
age of the loaders at the Merry Oaks is under two years. This strategy has greatly diminished any loader
downtime. In the event that a loader is down for an extended period the loader supplier is required to
supply a loaner.
If a long-term power outage occurred, generators would be utilized to keep the electrical equipment
running. McGill has not had this occur in its seventeen-year history.
Over long periods of time concrete will crack in areas of heavy use. Old concrete is removed and
replaced on an as needed basis.
Spills are addressed in the Spills and Accident Response Plan, Emergency Action Plan, annual training,
and Stormwater Pollution Prevention Plans. Employees have been trained to respond to spills according
to the type of spill, location, volume, etc. All spills are reported to the compliance manager for
documentation and reporting if necessary.
4.30
Plant personnel undergo monthly training for required OSHA topics as well as other safety topics
pertinent to the composting industry. Attendees are required to sign a roster, and the rosters are kept
by the human resources department.
4.31
If in the event that the facility permanently closes, all requirements listed in Rule 15A NCAC 13B .1410
will be followed so that North Carolina DEQ's requirements are satisfied. A closure plan would be
submitted to DEQ for approval prior to closure. The closure plan will include details on the following:
1. All feedstock and unfinished compost materials shall be removed from the site and taken to
a permitted solid waste facility within 180 days;
2. Finished compost materials left onsite shall comply with G.S. 130A-309.05; and
3. McGill shall notify the Division in writing upon completion of the requirements of the
removal of the compost materials.
Section 5
5.1
A site map labeled as Figure 2 illustrates the location of the biofilter and the blending area and is located
in Attachment E.
5.2
The facility maintains the required tree buffer around the operations area. No known true seasonal
variations or prevailing winds are present that would affect odor migration from the facility to adjacent
facilities on a consistent basis.
5.3
The plant manager records the wind speed and direction weekly in order to determine if there may be a
potential issue with odor migration. The date, time, site conditions, weather conditions, and wind
direction are noted. Beyond noting the weather conditions, McGill's policy is to process intake materials
in a timely manner in order to reduce the potential for odors.
5.4
When an odor complaint is received, the plant manager along with the compliance manager investigate
the complaint by noting the time of the complaint, the time that the odor was said to be detected, and
the wind direction and speed that day. If the odor is said to be happening currently, either the plant
manager or the compliance manager will investigate both onsite and offsite. Records will be researched
to determine where incoming feedstocks originated on the day of the odor complaint. The response to
the odor complaint will vary with each situation; however, each complaint will be fully investigated and
documented by McGill personnel.
5.5
McGill's odor complaint form is located in Attachment F. The form is filled out each time there is an
odor complaint and are kept by the compliance manager on McGill's server. The forms will be kept for
the duration of the permit as required.
5.6
Though the Merry Oaks facility has extensive odor controls in place, prevention is the primary strategy.
Central to this is good housekeeping, prompt and proper mixing and reliability of the aeration system.
1. Employees receive training on methods of how to best control odor through feedstock
management. This training occurs when an employee is hired and is discussed during employee
meetings.
2. Feedstock characteristics management is part of the process as they are unloaded Keeping
solids separate from liquid feedstock, getting feedstock properly mixed, and getting that mixture
onto aeration is key in odor management and is part of the composting process at McGill.
Attention must be given to both the ingredients and how they are put together. The available
waste materials and amendments must, when put together, fall within the correct moisture
range, C:N ratio and bulk density. Mixing ratios to acquire the desired C:N ratio are discussed in
Section 3.5 of this application.
4. The majority of residuals accepted at the facility have significant odor potential, so all are
handled in a very controlled manner. Getting incoming residuals properly mixed with a carbon
source and getting the mixture in an aerated pile is important.
5. Moisture is monitored during the composting process in order to determine if there is enough
moisture present for microbial activity.
6. The composting procedure followed at the facility requires that piles of material be placed in
bays where the compost is exposed to forced air until the composting process is complete. The
aeration of the piles is discussed in detail in Section 3.9.
7. Typically, there is no generation of leachate from the composting process, but if any should
occur it is mopped and incorporated back into the mixture. All liquids that come into the
blending area as a feedstock are blended with solid materials and carbon sources and
maintained within the building.
8. Weather is monitored daily for wind direction. However, since the composting process is in a
building, weather typically does not often affect the process.
9. Management of airborne emissions: Air removed from the processing and curing bays is forced
through a biofilter and is discussed in the following section.
10. Windrows are not utilized at the facility.
5.7
The Merry Oaks facility has a biofilter. Air is extracted from the building through a network of ducting
connected to three 50 HP fans. Each fan supplies air to a separate biofilter media section. This is
achieved through a header duct which connects to a series of distribution ducting under the media. The
media is made up of wood chips and Overs from the composting operation. The most recent media
change was in the summer of 2019. It is anticipated that the media will not require changing until at
least summer of 2022.
The only moving parts on the biofilter are the 3 fans. They are inspected daily and are served as needed
per manufacturer's recommendations. Spare components are maintained onsite, and a maintenance
person has the expertise to change components if required.
