5 Tech Revision 1 July PART II - APPLICATION CONTENT The following sections present a response to this introductory section WASTE ACCEPTANCE PLAN (b) The source, characteristics, and volumes of waste to be accepted are described in Sections to Subchapter E Requirements Also (b)(1) This facility will be authorized to receive permitted wastes as defined below. Waste acceptance and subsequent processing for re-use is based upon the types of wastes that make up the incoming waste stream. The facility will be developed in two phases based on incoming waste volumes. The maximum volume of incoming waste material during Phase I operations that may be temporarily stored at the facility while waiting to be processed, and have the recyclables sorted out, is estimated at approximately 3,500 cubic yards per day (yd 3 /day). The solid waste will remain in containers until ready for processing. It is expected that during Phase I operations, a maximum of 3,500 yd 3 per day of solid waste and recyclable materials will be stored at the facility at any time; this will consist of the materials in the containers and materials in the various stages of processing and recycling within the WSPA. When the incoming waste volume is nearing at the maximum of 3,500 yd 3 per day, and an evaluation of potential additional waste streams indicates an increase in waste volumes, Phase II will be initiated. After Phase II construction is completed, the maximum volume of incoming waste material during Phase II operations that may be temporarily stored at the facility while waiting to be processed, and have the recyclables sorted out is estimated at approximately 7,000 yd 3 per day. The solid waste will remain in containers until ready for processing. It is expected that during Phase II operations, a maximum of 7,000 yd 3 per day of solid waste and recyclable materials will be processed at the facility at any time; this will consist of the materials in the containers and materials in the various stages of processing and recycling within the WSPA. In accordance with 30 TAC (a)(2)(B), a maximum of 975 tons of MSW will be stored overnight, defined as sunset to sunrise. Based on this estimate of the solid waste data for 2-1

The average daily volume of incoming waste material, during Phase I operations, that may be temporarily stored on site while waiting to be processed, and recyclables sorted out, is estimated at approximately 3,500 yd 3. The solid waste will remain in containers until ready for processing. It is expected that a maximum of 3,500 yd 3 of solid waste and recyclable materials will be stored on site; this will consist of the materials in the containers and materials in the various stages of processing and recycling within the waste processing area. In accordance with 30 TAC (a)(2)(B), a maximum of 975 tons of MSW will be stored overnight, defined as sunset to sunrise. The projected daily, weekly, yearly, and five-year waste reception volumes based on average anticipated waste acceptance volumes during the Phase I operations are as follows: 3,500 yd 3 per day, 21,000 yd 3 per week (based on the maximum operating time of six days per week), 1,092,000 yd 3 per year, 5,460,000yd 3 per a five-year period. When the incoming waste volume is nearing the maximum of 3,500 yd 3 per day, and an evaluation of potential additional waste streams indicates an increase in waste volumes, Phase II will be initiated. After Phase II construction is completed, the maximum volume of incoming waste material during Phase II operations that may be temporarily stored at the facility while waiting to be processed, and recyclables sorted out, is estimated at approximately 7,000 yd 3 per day. The projected maximum daily, weekly, yearly, and five-year waste reception volumes based upon intended waste volume for Phase I and Phase II combined are as follows: 7,000 yd 3 per day, 42,000 yd 3 per week (based on the maximum operating time of six days per week), 2,184,000 yd 3 per year, and 10,920,000 yd 3 for a five-year period. The solid waste will remain in containers until ready for processing. It is expected that during Phase II operations, a maximum of 7,000 yd 3 per day of solid waste and recyclable materials will be stored at the facility at any time; this will consist of the materials in the containers and materials in the various stages of processing and recycling within the WSPA. In accordance with 30 TAC 2-4

9 generation rates discussed above and considering the average gate weight of the incoming waste stream of approximately 500 pounds per cubic yard, the population equivalent served by the facility is approximately 466,800 people during Phase I operations and 933,600 people during Phase II operations. The will recover a minimum of 10 percent or more by weight or weight-equivalent of the incoming waste streams. The recovered waste streams will be sold to recyclers for re-usage Volume Stored, Maximum & Average Time Waste Remains On-Site, List Intended Destination Of Waste Received At Transfer Station (b) (1) (B) The maximum volume of wastes and recyclable material stored processed at the facility is expected to be 3,500 yd 3 /day during Phase I operations and 7,000 yd 3 /day during Phase II operations. The average time waste is anticipated to be stored on site is two days and the maximum time waste is anticipated to be stored on site is three days. The wastes will be processed for recyclable materials and re-containerized. The recyclable materials will be sent to a recycling facility. The wastes will be sent to a TCEQ permitted solid waste disposal facility within 50 miles of the facility as indicated in Table In accordance with 30 TAC (a)(2)(B), a maximum of 975 tons of MSW will be stored overnight, defined as sunset to sunrise. The projected daily, weekly, yearly, and five-year waste reception volumes based on the average anticipated waste acceptance volumes during Phase II operations are as follows: 7,000 yd 3 per day, 42,000 yd 3 per week (based on the maximum operating time of six days per week), 2,184,000 yd 3 per year, and 10,920,000 yd 3 for a five-year period For Registrations, Establish Why Facility Qualifies For Registration Under (b) (2) After granting the RA for the facility, the will recover a minimum of 10% or more by weight or weight-equivalent of its incoming waste stream for reuse or recycling, which qualifies for materials recovery requirements. All non-recyclable waste received at the will be disposed at an approved TCEQ solid waste management facility within 50 miles of the facility, which qualifies for the distance to landfill requirements. 2-5

11 It is expected that during Phase II, a maximum of 7,000 yd 3 /day of solid waste will be stored processed on site; this will consist of the materials in the containers and materials in the various stages of processing and recycling within the waste processing area. In accordance with 30 TAC (a)(2)(B), a maximum of 975 tons of MSW will be stored overnight, defined as sunset to sunrise. Based on this estimate of the solid waste data for Gainsborough Waste, it is expected that a typical unit of non-recyclable solid waste arriving on site would, at a maximum, remain on site for approximately 3 days. The average length of time solid waste will remain on site is 2 days. This includes the time for waste processing and the time to fill a container for transportation to an offsite TCEQ-approved landfill or to a third-party recycler Permitted Waste The composition of permitted waste the facility will receive for material recovery consists of the following types of materials: Untreated Lumber Untreated lumber includes boards, strip lumber, plywood, particleboard, and paneling; Untreated Sheetrock Sheetrock is made of gypsum, which is a naturally-occurring rock found throughout the world. Gypsum, whose chemical name is hydrous calcium sulfate, is an inert, non-toxic material with many beneficial uses. These uses include use as a soil additive (sometimes called land plaster) to overcome the corrosive effect of alkalinity and benefit crops like alfalfa, corn, cotton, and wheat. Gypsum is also used as a filler additive to drugs and cosmetics and as an ingredient in canned vegetables, flour, ice cream, blue cheese, and other foods. It is the only natural substance that can be restored to its original rock-like state by the addition of mere water. Only untreated sheetrock will be recycled, any painted or chemically treated sheetrock will not be recycled; Cardboard; Clean Wood and Clean Brush Debris Clean wood and clean brush debris includes trees, branches, limbs, leaves, grass cuttings, brush, and other organic vegetation; Inert Fill Materials Inert fill materials include bricks, stones, concrete, soil, gravel, sand, and dirt; 4-10

12 Treated Lumber Treated lumber includes boards and strip lumber that has been treated with chemical agents. Also included in this category is lumber, plywood, or other process wood materials with painted surfaces; 4-10a

13 This waste composition is based on historical input and the potential market opportunities identified by Gainsborough Waste. Material not recycled will be disposed offsite at a TCEQapproved landfill within 50 miles from the facility. The segregated recyclable materials (i.e., metals, untreated wood, cardboard, concrete not considered a solid waste) that have been segregated into distinct areas comprised of the same type of materials, may remain onsite for a maximum of 180 days, or until the materials become a nuisance. The Type V-TS Facility will maintain documentation at the facility that all wastes are being adequately managed by other licensed or permitted facilities. Wastes accepted at the Type V-TS Facility will be recycled or disposed of at an authorized solid waste management facility. The maximum time processed or unprocessed waste will remain on site is for three days. The maximum amount of processed and unprocessed waste to be stored processed at the facility is 3,500 yd 3 /day during Phase I, and 7,000 yd 3 /day during Phase II. In accordance with 30 TAC (a)(2)(B), a maximum of 975 tons of MSW will be stored overnight, defined sunset to sunrise. 4.5 CONTAMINATED WATER MANAGEMENT 30 TAC Water Pollution Control The will take the necessary steps to control and prevent the discharge of contaminated water from the facility. Surface drainage in and around the facility will be controlled to minimize surface water running onto, into, and off the working areas because all solid waste processing will be conducted within a waste storage and process area (WSPA) that includes containment walls and ramped entry to minimize run-on and run-off (see Figures 18A, 18B, and 18C of Appendix C). Sumps will be provided for the collection of all water generated within the WSPA. Processed wash waters generated by the facility cleaning operations and storm water that has come into contact with solid waste will be collected within the sumps. All liquids will be removed from the sumps using vacuum trucks or similar equipment on an as- needed basis, but in no case will water within the confines of the WSPA remain for more than 24 hours when operational. The liquids will be used 4-15
