Memo
To Craig Adair, Crossroads Solar Grazing Center
From Mark Bonifas, P.E., LEED AP
Subject Solid Waste
Project Number 17078
Verdantas is providing the following information to support Crossroads Solar I, LLC’s preparation of its Certificate Application for an Electric Generation Facility in accordance with Ohio Administrative Code (OAC) 4906-4-07(D)(2) and (3) The Crossroads Solar Grazing Center is anticipated to have a generation capacity of up to 94 MWAC
(D) The applicant shall provide information on compliance with solid waste regulations. Examples of relevant information include:
(2) Information regarding solid waste during construction
(a) An estimate of the nature and amounts of debris and other solid waste generated during construction.
Anticipated solid waste materials generated during construction will largely consist of cardboard, wood, pallets, foam packaging, spools, paper, and plastics (shrink wrap and banding) that are associated with the packaging and shipping of the solar panels, electrical equipment, and metals. General refuse may also be generated. Some additional solid waste may be generated if damaged equipment and materials are received, or damage occurs during construction. Secondary amounts of construction materials may include small amounts of construction materials (i.e., excess concrete, extra bolts, and wiring, etc.) associated with installation activities. Based on an average solid waste generation for this type of facility of 111.5 cubic yards per MW, this Facility is estimated to create approximately 10,480 cubic yards of solid waste during construction.
(b) The proposed method of storage and disposal of these wastes.
The wastes generated during construction of the Facility are expected to be nonhazardous solid wastes. Hazardous wastes are not anticipated to be generated during construction A variety of storage and disposal alternatives may be used. While we understand that emphasis will be placed on finding sustainable solutions to manage materials and waste (i.e., reuse and recycling), it is anticipated that individual materials/waste will be segregated and stockpiled or stored in dumpsters located in the temporary construction laydown areas. Best management practices should be implemented to minimize contact with stormwater or minimize stormwater runoff in the storage areas (if needed based on the material). If the materials are not reused or recycled, the material is expected to be managed at
an appropriate solid waste management facility in accordance with federal, state, and local regulations.
(3) Information regarding solid waste during operation of the facility
(a) An estimate of the amount, nature and composition of solid wastes generated during the operation of the facility
During operation, we estimate that negligible amounts of solid waste will be generated. Anticipated solid waste materials generated during operation will largely consist of cardboard, wood, pallets, foam packaging, paper, and plastics (shrink wrap and banding) that are associated with the packaging and shipping of replacement solar panels, electrical equipment, and metals. General refuse may also be generated. Based on an average solid waste generation for this type of facility of 0.15 cubic yards per MW per year, this Facility is estimated to create approximately 14 cubic yards of solid waste annually In addition, there may be additional small amounts of solid waste contributed by the sheep grazing activities planned for the Facility. These would be of a type typical of livestock operations.
(b) Proposed methods for storage, treatment, transport, and disposal of these wastes.
The wastes generated during operation of the Facility are expected to be nonhazardous solid wastes. Hazardous wastes are not anticipated to be generated during operations. A variety of storage and disposal alternatives may be used. While we understand that emphasis will be placed on finding sustainable solutions to managing materials and waste (i.e., reuse and recycling), it is anticipated that individual materials/waste will be segregated and placed directly in trucks for offsite transportation, or temporarily placed in dumpsters located on site. Best management practices should be implemented to minimize contact with stormwater or minimize stormwater runoff in the storage areas (if needed based on the material). If the materials are not reused or recycled, the material is expected to be managed at an appropriate solid waste management facility in accordance with federal, state, and local regulations.
