The first is grease trap waste. The company (B&B) provides a grease trap pumping service to local restaurants, which generates sufficient volume for the operation on a year-round basis. The other material is wood chips, which are provided by two local, privately -owned tree service companies. Material from the general public is not accepted. (2) Estimate of materials On average, the facility receives 20 cubic yards of grease trap waste and 40 cubic yards of wood chips on a monthly basis for the purpose of composting. (3) Design capacity of the facility The incoming volume for a year would be 240 cubic yards of grease trap waste and 480 yards of wood chips, although on average the company produces 10 windrows of compost annually. Production is limited to one compost pad, a six-inch thick concrete pad that measures 43 feet in width by 48 feet in length. An area for raw material storage is provided immediately west of the pad. (4) Compost recipe The recipe consists of two items, processed grease trap waste and wood chips. Carbon to nitrogen ratio (C:N) testing and calculations have not been performed. (5) Methods used The same amount of material (20 yards of grease trap waste and 40 yards of wood chips) are used to create each and every windrow and are mixed as outlined in Item (9) of Section 1 below. No shredding is performed at the site. Mixing and proportioning are done with the backhoe bucket. (6) Process flow diagram A process flow diagram is included as Exhibit A to this application. (7) Grading and sloping Runoff from the site is directed to a pipe that feeds into a 1000-gallon storage tank, resulting in little or no ponding of water. (8) Anticipated process duration The anticipated process duration is generally about one month in length. For example, if a new windrow is created on the first day of the month, it would be turned for the first time approximately three to five days after creation, with temperatures monitored each weekday. The windrow is then turned a minimum of once per week. After a period of 30 to 35 days, the windrow is moved and a new one is created and the process resumes. (9) Compost method The treated, dewatered (solid) grease trap waste is dumped onto the pad from a roll -off container via a truck from an adjacent dewatering facility also operated by the company. Wood chips are then added using a backhoe bucket. The product is then turned and turned with the backhoe until thoroughly mixed. This blended material is then shaped into windrows that are anywhere from eight to 12 feet in width and five to seven feet in height. The windrows remain in place for a minimum of 30 days and occasionally as often as 45 days depending on the need for space. Temperatures are maintained at or above 131 degrees Fahrenheit for at least 15 days. Windrows are turned at least five times while the temperatures are above 131 degrees, normally one to two times per week as needed. Temperatures are monitored once per work day, using a three -foot -long temperature probe. The finished material is removed from the pad and stored on site, and a new windrow is then created using the same process. (10) Surface water control features The facility is designed to control the possibility of runoff entering ground or surface waters. Runoff from a normal rainfall event is directed to a 1000-gallon storage tank located to the south side of the pad, and the tank is pumped as needed and transported to the Town of Franklin's Wastewater Treatment Plant (WWTP). (11) Process / contact water Process and/or contact water is handled in the same manner as described in Item 10 of Section 1 above. (12) Amendments There are no amendments added to the grease trap waste and wood chips. (13) Item 13 in Section 1 is not applicable to this permit application as it is not a Large Type 3 facility. l 2. Section 4 Operation Plan (1) List and description of equipment and equipment maintenance Dewatering box Roll off truck Backhoe Dump truck All items are maintained as needed. (2) Site security and access control The compost pad is located in an interior portion of the company's site and is only open during normal business hours. Otherwise, it is secured behind a locked gate. (3) Operator on duty when site open for public use Access to the compost pad is only available during normal business hours, and the operator or his designee are the only ones allowed to perform any function associated with the operation. Members of the general public are not allowed access to the site without the operator or his designee present. (4) Access road of all-weather construction / maintenance The access road to the compost pad is , made of concrete, which turns into a short gravel drive to the actual site. The road is easily maintained and requires little or no maintenance, which can be performed with a backhoe as needed. This same access road is used for other company business as well. (5) Days and hours of operation, day -end procedures The company operates from 8 a.m. to 4:30 p.m. Monday through Friday unless other circumstances warrant. Any functions performed at the site, such as turning of windrows, occur during this time. As to specific day -end procedures to perform, the leachate tank is checked daily to determine if it needs to be pumped. Also, the drainage ditch is checked for possible debris and is cleaned if needed. (6) Signage As the general public is not allowed on -site, the need for signage is essentially non-existent. The tree service vendors who provide wood chips are informed in advance where to dump material for future use. I1 - (7) Permanent boundary markers Not applicable to this operation/site. (S) List of personnel required and their responsibilities • Jeremy Decker - Yard Supervisor As yard supervisor, this employee maintains overall responsibility for the day-to-day maintenance of the compost pad and the windrows, which he creates, mixes and turns as needed. (9) Narrative description of compost process from beginning to end (A) Solid grease waste from the dewatering container is placed on the compost pad and immediately mixed with wood chips. (B) Temperature monitoring occurs at least once each weekday of operation (not on holidays) and windrows are turned weekly. (C) Process continues until finished product is ready to be hauled off/ away or stored on site. (10) Method for screening loads for unacceptable waste No "unacceptable waste" is allowed in the mix. (11) Anv special handling of materials None, unless a description of the dewatering process of the grease trap waste is necessary. An operations manual for this process exists and is controlled under another permit. (12) Any amendment to be added to compost None. (13) Processing activities to prepare materials for composting Dewatering of grease trap waste. Only wood chips that are already ground are accepted. (14) Pile sizes Generally speaking, the windrows range in width from eight to 12 feet and from five to seven feet in height. The windrows also range from 25 to 30 feet in length. (15) Describe compliance with time. temperature and turning; requirements Compost is kept on the pad for approximately 30 days. Temperatures are monitored daily using a three -foot -long probe. Windrows are turned weekly via backhoe. (16) Describe any other monitoring Not applicable. (17) Method of aeration provided Turning via backhoe is only method used. (18) Provide an odor management plan Clean wood chips are added to existing compost if odor becomes an issue. Due to the location of the pad within the business facility, there are no residences in the nearby vicinity that would be affected. (19) Describe compost testing and method for collecting samples Testing is performed semi-annually. Samples are collected with a clean shovel and disposable gloves and are sent to Earth Environmental or Pace Analytical for testing. (20) Describe distribution and ultimate use of finished compost Finished compost is stored on site. The finished product is also provided free of charge to residents who use it for a variety of purposes. (21) Describe recordkeeping and annual reporting Data is recorded in an annual calendar planner as to dates of creation, temperature readings and turnings, and movement to another location. Annual reports are submitted each July in the format provided by the state. (22) Describe operational activities for surface water and process water Rain water that is collected on the pad is directed by gravity flow to a leachate tank, which is pumped as needed. Any process water would also be channeled to the leachate tank. (23) Plan for fire prevention A small fire in the windrow could be extinguished by using the backhoe to spread out the material and snuff any flames. Otherwise, 911 would be called and the Franklin Fire Department would respond. The fire department is less than two miles to the north and could be on site in as little as three to five minutes. (24) Plan for maintaining faciliry property Because the facility property has more than one use, a variety of actions are used to minimize noise, vectors, litter, dust and any other airborne particulates. As to the compost pad/windrows, at the end of each business day, all areas are properly maintained to avoid any of the items outlined above. Litter and blowing dust leaving the property are not issues with this process. (25) Contingency plans for wind. heavy rain, snow, freezing weather A steep embankment to the immediate west of the compost pad shields the windrows from westerly wind, which is most prevalent in this area. Impacts on the windrow from a heavy rain or snow are minimal, as any runoff is handled as described in Item 22 above. Freezing weather also has a minimal impact. (26) Site safety procedures As access to the site is limited to the public, safety measures are directed primarily to employees. Generally speaking, only the person operating the backhoe is at the site during the initial mixing of the product and for any turning afterward. Caution is also exercised when the finished product is removed from the pad. (27) Describe closure procedures for this site The dewatered grease trappings would be taken to the Macon County Landfill. Wood chips from the tree service providers would no longer be accepted. The concrete pad could be repurposed by the company as needed or if needed. If not needed, could be broken up and hauled away. Should the site become inactive, it would take less than 60 days to remove all items from the site. 4 - Signature page of applicant Name of Facility: B&B Concrete Products, Inc.
