31 Garland County Department of Environmental Services Compost Facility Location Restriction Standards 4.0 LOCATION RESTRICTION STANDARDS In accordance with Arkansas Regulation 22, compost facilities are responsible for selecting sites that meet certain location restrictions to help ensure that the facilities do not pose an unreasonable probability of adverse effects on public health or the environment. This section addresses these location restriction standards outlined in Chapter 8 (Compost Facilities) of Regulation 22 as related to the proposed compost facility. 4.1 FLOODPLAINS DEMONSTRATION This section of the regulation specifies that compost facilities should not be designed in a manner that will restrict the flow of a base flood or reduce a temporary water storage capacity of the floodplain. Applicants for a new compost facility are required to demonstrate to the ADEQ that the facility is in compliance with this section of the regulation. The most recent Flood Insurance Rate Map (FIRM) published by the Federal Emergency Management Agency (FEMA), presented as Floodplains Demonstration located in Appendix 4-A, indicates that the proposed landfill site is not located within the 100-year floodplain. Currently, the Department of the United States Army Corps of Engineers (COE) recognizes the information published by FEMA as the authoritative source regarding floodplain determination. 4.2 WETLANDS DEMONSTRATION This section of Regulation 22 specifies that new compost facilities shall not be located in wetlands unless the owner or operator can make the demonstration defined in Section of Regulation 22 to the Director of ADEQ. To comply with this section of the solid waste regulation, the Corps of Engineers, Little Rock District (LRCOE) was contacted on December 1, 1998, followed by a supplementary letter dated December 11, 1998 concerning jurisdictional wetlands in the area of the new GCCG proposed Class 4 Landfill. A letter dated January 20, 1999, from the LRCOE states that there are jurisdictional areas on the property subject to regulation pursuant to Section 404 of the Clean Water Act. No work involving the discharge of dredged or fill material (land clearing, ditching, filling, leveeing, excavation, etc.) within the limits of the jurisdictional wetland areas identified by the LRCOE will be performed. Demonstration that the proposed site is in compliance with this Section of the application can be found in Appendix 4-B. B&F Project No. 7/2852/1009 January

32 Garland County Department of Environmental Services Compost Facility Location Restriction Standards 4.3 ENDANGERED SPECIES Section of the regulation specifies that compost facilities and practices shall not cause or contribute to the taking of any endangered or threatened species of plants, fish, or wildlife. In addition, the facility practice shall not result in the destruction or adverse modification of the critical habitat of endangered or threatened species as identified in 50 CFR Part 17. Threatened and endangered species determinations for the surrounding landfill site within the parent tract were requested from the U.S. Fish and Wildlife Service and the Arkansas Game and Fish Commission. Both agencies reported that there are no federal endangered, threatened, or candidate species within the surrounding landfill site. Applicable correspondence associated with this location restriction standard is included in Appendix 4-C of this document. B&F Project No. 7/2852/1009 January

A sign shall be posted at the site entrance to provide the following information: facility permit number, name of site, types of waste accepted, unacceptable materials, and emergency telephone numbers. 2.3 ACCESS CONTROL Access to the adjacent landfill and compost facility is controlled and managed by employees of GCDES Class 4 Landfill. Access to the working area of the compost facility is via the permanent perimeter road at the landfill. Temporary access roads are constructed by GCDES on an as-needed basis. The roads shall be maintained as necessary to provide access during periods of inclement weather. Compost operators shall prohibit any unauthorized access to the compost area. Security monitoring devices shall be installed and a regular sheriff s patrol shall further deter unauthorized entry and abuse of the facility. 2.4 WASTE SCREENING PROCEDURES Acceptable Waste The GCDES Compost Facility will accept residential and commercial compost waste generated from Garland County. The waste accepted shall consist of yard waste and other vegetative materials such as grass clippings, straw, leaves, shredded or chipped brush and tree pruning s Screening Process Leaf, straw, and yard waste brought to the site will be deposited in the receiving area located northeast of the proposed compost facility. The scale house operator will be responsible for preliminary checking of the material for compliance to the facility rules and regulations. Preliminary waste screening and inspection of in-coming yard waste will take place at the scale house. Signs will be installed near the scale house B&F Project No. 7/2852/ January 2008

62 Garland County Department of Environmental Services Compost Facility Operating Plan & Narrative instructing residents on acceptable composting material. The compost facility operator will be responsible for final checking of the material for compliance to the facility rules and regulations and will direct the heavy equipment operator as to when and where to move the material from the receiving area. Depending on the time of year, this may happen as often as once an hour. As a minimum, the receiving area will be cleared at the end of the day and placed in windrows for processing. Bulking agents (such as wood chips, dry straw, sawdust) may be added to feedstock materials to maintain adequate porosity and help to maintain aerobic conditions in the compost pile during the mixing process. The collected material will be run through a tub grinding operation to shred the leaf and yard waste prior to final placement in windrows. The tub grinding operations is performed a minimum of twice each year, typically in the spring and fall. After the tub grinding, the material will be moved to the appropriate windrow where monitoring and aeration through windrow turning will take place. It will be the foreman s responsibility to monitor the composting operations. A daily record of site and weather conditions will be kept at the scale house, with copies sent to the Garland County Department of Environmental Services Director weekly and the State DEQ quarterly.

64 Garland County Department of Environmental Services Compost Facility Operating Plan & Narrative Waste Disposal Contingencies Hazardous waste found to be contaminating the compost product, will be removed from the site by properly licensed personnel and disposed of by only those methods approved by law. Non-hazardous material contaminating the compost product will be separated and if allowable, blended and used as landfill cover Prevailing Winds The prevailing wind direction is from the west and southwest directions. There is a tree buffer along the perimeter of the site. The closest structures are 2,000 feet away from the composting operation and are separated by a tree buffer. On site personnel will be responsible for litter control and maintenance of the compost site. 3.0 STORMWATER MANAGEMENT PROCEDURES A stormwater management system is used at the adjacent GCDES Class 4 Landfill site to control run-on and runoff. The system is designed to minimize erosion and induce settling of suspended sediments. Stormwater runoff within the compost areas is directed away from the facility by a combination of culverts and perimeter ditches, and is routed to a 4-acre settling pond. Erosion and sediment control measures such as silt fences, hay bale or rock check dams, and erosion control matting may be used to reduce the potential for excessive sedimentation problems. 3.1 WATER CONVEYANCE Peak flows from the 25-year, 24-hour storm shall be contained by the on-site settling pond system. All watercourses are designed to reduce erosion. Normally, ditches and swales shall be grass-lined, and shall have a maximum gradient of five (5) percent. Steeper sloped portions of ditches shall be rock-lined or use erosion control matting, letdowns, or other appropriate measures. 3.2 SYSTEM MAINTENANCE PROCEDURES It is very important that the stormwater management system at the site is maintained so that it may function properly during a storm event. The following maintenance is recommended especially after large storm events. Keep all ditches and swales unobstructed. Remove sediment from ditches, swales, sediment basins, and sediment barriers routinely. Sediment controls are most effective when sediment is removed regularly. B&F Project No. 7/2852/ January 2008

65 Garland County Department of Environmental Services Compost Facility Operating Plan & Narrative Check and clean rock check dams and outlet control structures of sediment and other materials that may restrict flow. Periodically inspect the stormwater system for damage and repair immediately. Inspect and clean the stormwater system following a major storm event. 4.0 HEALTH AND SAFETY PROCEDURES 4.1 INTRODUCTION The primary purpose of this section is to help prevent personal injuries or illnesses that may be caused by conditions typically found at a compost facility. It is not the intent of this section to establish a comprehensive safety program for GCDES Compost Facility; rather to augment the existing program with awareness of special hazards related to compost facilities General The GCDES Compost Facility should be maintained in such a manner as to continually provide a safe place to work. This can be done only by constantly THINKING SAFETY. Analyze jobs, work areas, and procedures from a safety standpoint, and learn to recognize potentially hazardous actions or conditions. When a hazard has been recognized, immediate steps should be taken to eliminate it by corrective action. If corrective action is not possible, guard against the hazard by proper use of warning signs and devices, and by the establishment and maintenance of safety procedures. The safety hazards associated with compost operations are many and varied. Accidents may be prevented by using good common sense, applying a few basic rules, and particularly by becoming knowledgeable of the hazards peculiar to a job Reporting and Investigation of Accidents and Illnesses Accidents must be reported PROMPTLY to the employee's immediate supervisor for evaluation and/or investigation. Immediate reporting is mandatory not only to comply with applicable laws and regulations, but also to ensure that steps are taken to correct the conditions that contributed to the accident. Since every accident includes a sequence of contributing factors, it is possible to avoid a repeat of the first event by recognizing and eliminating these factors. The removal of just a single factor could prevent a recurrence. 4.2 POTENTIAL HAZARDS Compost facility personnel work in all types of weather, with many different types of heavy equipment, and with a variety of materials presenting diverse hazards. For this reason, safety equipment must be used and maintained in a sanitary and reliable condition. First-aid kits shall be easily accessed at the facility. B&F Project No. 7/2852/ January 2008

66 Garland County Department of Environmental Services Compost Facility Operating Plan & Narrative 4.3 HAZARD ABATEMENT PROCEDURES The following procedures, guidelines, and recommendations represent standards in the compost industry presently in use to mitigate or eliminate the various safety and health hazards, which may exist at the GCDES Compost Facility Personal Protective Equipment Personal protective equipment must be worn as necessary whenever hazards of processes or environment are capable of causing injury Operations Safety Transporting and unloading compost waste is a serious area of safety concern. Uncontrolled dust, differing flows and direction of traffic and operational equipment, and equipment operation angles pose dangers to those in the vicinity of the working face. For these reasons, safeguards shall be provided on compost equipment to protect the operator and the vehicle. Compost operating personnel who direct the placement of the delivery vehicles must take care to maintain sufficient clearance between the vehicle and the compost equipment. Normal safety precautions shall be exercised while operating or working in the vicinity of heavy equipment Fire Prevention and Control Methods Fire hydrants located on the property will provide adequate fire protection and are the source for windrow watering. Portable fire extinguishers are kept on all compost operating equipment and at the transfer station office. Personnel shall be trained in the use of these extinguishers and should become familiar with their locations. The extinguishers shall be inspected annually and maintained in a ready condition. 4.4 EMERGENCY PROCEDURES The emergency conditions discussed in this section are general. It is not intended to cover every possible emergency situation. The site personnel must be constantly aware that problems may arise. A list of important phone numbers should be updated regularly and should be kept at the office. Emergency telephone numbers are as follows: All Emergencies call 911 Security Guard (to be posted once operations start) ADEQ Department of Solid Waste: (501) ADEQ Department of Hazardous Waste: (501) B&F Project No. 7/2852/ January 2008

All fertilizer and soil amendment products must be registered with the Arkansas Office of Natural Resource Services before being offered for sale. Compost utilization may be distributed for agricultural and non-agricultural use including, but not limited to the following: a) Agricultural uses. b) Homeowner use. c) Nurseries and tree farms. d) Floriculture and turf-grass production. e) Other agricultural and horticultural uses. f) For landscape applications, including also highway medians and roadsides. g) For public parks and grounds, sports fields and stadiums, golf courses, cemeteries, and similar applications. h) On forestlands. 5.2 COMPOST END USES AND MARKETS The final compost product will be sold to residents of Garland County. If supplies allow, the product will also be made available to the commercial market. All excess material will be processed, blended, and used by the County for either landfill cover or roadside mulch following road-paving projects. 5.3 COMPOST QA/QC A certified lab will be contracted by the County to conduct quarterly sampling of the compost material. Test parameters will be in accordance with the rules and regulations for Composting Operations by the State of Arkansas. These results will be forwarded to the State DEQ and will be used to reduce the County s liability associated with residential use. B&F Project No. 7/2852/ January 2008
