City of Raleigh Yard Waste Center
Facility Background Information
1.1 Facility Description
The City of Raleigh Yard Waste Center, herein referred to as the Yard Waste Center, was
opened in November 1992. The facility is located on the east side of New Hope Road south of
the closed Wilders Grove Landfill. The facility address is:
900 New Hope Road
Raleigh, NC 27602
[phone]
The Yard Waste Center accepts only land clearing debris, yard waste, unpainted wood waste,
and silvacultural waste. Materials are accepted for treatment and processing or composting
only. No disposal is conducted at the Yard Waste Center. This facility is a Large Type 1 facility
on the basis of the definition contained in Section .1402 (f)(1) and (f)(7) of the Solid Waste
Regulations.
Portions of the facility are occasionally used to process storm debris from hurricanes, ice
storms, and other natural disasters. Such debris may be processed by City staff or by a US
Army Corps of Engineers contractor. These activities are generally confined to the permitted
processing areas.
Finished compost, wood chips, mulch, and leaves are sold directly to the public after
processing. City departments use finished product at no charge for various applications.
1.2 Observed Violations
On August 30, 2017, a Facility Compliance Inspection was conducted by the NCDEQ, DWM,
Solid Waste Section followed by two follow-up inspections on October 31, 2017, and December
6, 2017. The following violations were observed:
• Windrow dimensions for active composting shall not exceed 8 feet in height x 15
feet in width unless approved by Division.
o The facility is now in compliance with this requirement.
• Stockpiling of all feedstocks and finished product must be limited to a maximum
of 30 feet in height by 50 feet in width.
• The leaf storage area did not have any discernable windrows at the time of the
inspection and appeared to be over one acre in size.
• City of Raleigh, Yard Waste and Recycling Facility needs to immediately stop
adding incoming material to the stockpile (backlog) areas.
1.3 Facility Modifications
This mitigation plan is constructed in phases to allow for budget approval steps. The priority will
be to process all incoming material (feedstock) into composting windrows and stop adding
material to backlog stockpiles. The second priority will be to address a large stockpile area east
of the scale house that was created using Hurricane Mathew Debris, herein referred to as
stockpile 1, and one large stockpile north of the scale house, herein referred to as stockpile 2.
Both stockpiles are shown in Appendix A, Figure 1.

1.4 Source of Waste Processed
The Yard Waste Center is intended to serve the residents and businesses of the City of Raleigh
and Wake County, as was established in the 2017 Permit Renewal. The City intends to accept
yard waste from Wake County or other local governments as needed on a mutually agreeable
basis. The City does anticipate the need for additional personnel and equipment to manage
both stockpiles in addition to the current volume of incoming material.

2 Inspection Mitigation Plan
2.1 Phase 1 - Initial Corrective Action
• An area south of the leaf stockpile within the permitted operating plan has been cleared
and properly graded. In this location, all incoming leaf collection material from 2017 will
be placed in stockpiles that meet permitted requirements.
• All incoming material will be processed and placed into windrows beginning immediately.
No incoming material will be added to the backlog stockpiles. To achieve this, the City
will need to purchase additional equipment and increase staff resources.
• The Yard Waste Center will procure needed rental equipment to process all incoming
material and improve the sites operational layout, allowing material to be processed
more efficiently.
• All windrows have been processed from the operational area closest to the paved pad
south of the scale house. This area will be graded to improve drainage. Once this area is
graded, it will be used for compost production and stockpile 1 will be removed.
• The Yard Waste Center will complete a Business Plan in preparation for Fiscal Year
2019 Budget. The plan will include any additional equipment and personnel needed to
process all incoming material in a timely manner to prevent future backlog of
unprocessed material as well as processing stockpile 2 and the leaf stockpile.
• A sample collected from Stockpile 2 was tested for STA Certification and passed.
2.2 Phase 2 - Modification of "The City of Raleigh Yard Waste Center Operations Plan"
The City of Raleigh Yard Waste Center Operations Plan will be modified to reflect the
revisions needed to facilitate the processing of all incoming materials into marketable
products. The Yard Waste Center projects to be operating 100% in accordance with the
new operations plan by February 2019.
The Yard Waste Center will procure needed equipment identified during the business
plan development to operate in accordance with the new operations plan.
The needed equipment will not be received before February 2019 at the earliest. The
rental equipment procured in phase 1 will be utilized until then to maintain compliance.
2.3 Phase 3 - Processing of Stockpile 2 and Leaf Stockpile
• The City of Raleigh Yard Waste Center is exploring the possibility of utilizing an external
contractor to assist in removing all or a portion of the stockpiled material. The possibility
of utilizing an external contractor to assist in rearranging stockpile 2 onsite is also being
explored.
Yard Waste Center
Inspection Mitigation Plan (Rev. 1) — January 2017

City of Raleigh Yard Waste Center
• If the decision is to separate and rearrange stockpile 2 onsite, the City of Raleigh
personnel or contractor will break up stockpile 2 and place the material in the designated
areas shown in Appendix A, Figure 2. What remains of stockpile 2 and the material
being placed in designated areas will be placed in stockpiles that meet permitted
requirements.
• Material from stockpile 2 may also be used to repair erosion on Wilders Grove Landfill.
• The screening of stockpile 2, or its multiple smaller piles after rearranging, will resume
by February 2019, once additional resources are procured.
o Material from the leaf stockpile will be added to windrows during construction of
the compost windrows.
o The mulch material will be collected in stockpiles that meet the permit
requirements and sold.
o The compost (fines) will be collected in stockpiles that meet the permit
requirements and sold.
o The overs will be collected and placed in windrows for composting.
• The plan will have a goal to process, sell or rearrange all material in stockpile 2 and the
leaf stockpile within two years. Any material that has not been processed at that time will
be stockpiled to meet the permitted requirements.
