Section 096-401-4 - Landfill OperationsA.Operations Manual. The landfill operator shall prepare and maintain an operations manual of current policies and procedures for the landfill. (1)Revised Operations Manual. Prior to commencement of operations of a new or expanded landfill, the operations manual provided with the application pursuant to section 2(L) must be revised to reflect any changes which occur during the landfill licensing and construction processes. All existing landfills, other than construction/demolition, landclearing debris and wood waste landfills less than 6 acres in size, must submit a revised operations manual in conformance with this section to the Department for review and approval as part of the annual report due in 1999. These facilities must comply with the operating requirements of this section no later than 90 days after receiving Departmental approval of the revised operations manual.(2)Certified Copies. The landfill operator shall issue certified copies of the operations manual being used at the landfill to the Department and to key operating and management personnel of the landfill. In addition, a certified copy must be available for use at the facility at all times. The landfill operator is responsible for providing timely updates to all certified copies, distributing certified copies to individuals whose job assignments require them, and making and distributing changes to policies and procedures to the certified copies as they are implemented.(3)Contents. The operations manual must include the information necessary to enable supervisory and operating personnel, and persons evaluating the operation of the landfill, to determine the sequence of operation, policies and procedures, and monitoring, maintenance, inspection, and legal requirements that must be followed for safe, orderly and environmentally sound operation on a daily, yearly, and life cycle basis. The operations manual must address each of the areas identified in this section. Legible copies of the record drawings must be included in the operations manual or must be readily accessible to operating personnel.(4)Annual Review. The operations manual must be reviewed annually by the operator and updated as necessary.(5)Training. The landfill operator shall familiarize operating personnel with relevant sections of the operations manual. For new landfills or expansions of existing landfills, the landfill owner or operator must demonstrate compliance with the training requirements in section 4(B) prior to commencing landfill operations. For existing landfills, the landfill owner or operator must demonstrate compliance with the training provisions for key personnel within two years of the effective date of these rules.B.Operator Training and Certification Program. At least two key personnel must be trained in the operation of, and regulatory requirements for, the landfill. Key personnel must complete a training course, and must be familiar with State solid waste regulations and the site-specific operations manual. Landfill owner/operators may develop site-specific training programs for key personnel, or may gain certification through the Solid Waste Association of North America (SWANA) operator training certification program. Site specific training programs must be sufficient to demonstrate that key personnel have adequate knowledge to operate the landfill in accordance with the provisions of the site-specific operations manual, and must include provisions for 8 hours annually of refresher training. Landfill owner/operators must document training completed by their key personnel and keep this information on file for 5 years. SWANA certification is valid for a three year period. Key personnel must maintain a valid SWANA certification or maintain up-to-date site-specific training at all times.
C.Operating Requirements. Each landfill must be operated so that it does not contaminate ground or surface waters outside the solid waste boundary. Except for construction demolition, land-clearing debris, and wood waste landfills, all existing landfills must comply with the operating requirements of this subsection. (1)Acceptable Solid Waste and Waste Characterization(a) A landfill may accept only solid wastes or special wastes as allowed by the Department in the landfill's current license or as licensed under subparagraph (b) below. Special wastes must be handled as described in the landfill's approved operations manual. Landfills may not accept for disposal wastes that are determined to contain free liquids according to the Paint Filter Liquids Test (E.P.A. Method 9095B, Revision 2, 2004). (i) Municipal solid waste combustion ash may be co-disposed with municipal solid waste in landfills that meet the liner design standards of these rules provided that waste characterization is performed in accordance with section2(F)(10).(ii) Dredge materials or contaminated soils with concentrations of contaminants that exceed regulatory limits for hazardous waste, or that have a concentration of 50 mg/kg or greater dry weight of PCBs, are considered a hazardous waste. Disposal of these and other hazardous wastes requires review and approval by the Department under 06-096 CMR ch. 850-858.(iii) All ash proposed for disposal at a landfill must be fully characterized at the source of generation, with statistical analysis performed in accordance with the requirements of EPA SW-846, Test Methods for Evaluating Solid Waste, Third Edition, Volume II, Chapter 9, 2013. This testing must occur when the ash is first proposed for disposal.(iv) Solid wastes and special wastes permitted for acceptance as allowed by the landfill's current license must be characterized on an on-going basis in conformance with the characterization plan approved by the Department.(b) Applications for the one-time or on-going acceptance of special waste at a landfill must conform to the applicable requirements of 06-096 CMR ch. and 06-096 CMR ch. 2. The application must include the following:(i) The name and address of the owner or operator and the generator of the waste;(ii) A description of the facility processes that generated the waste, if applicable;(iii) A description of the waste and an estimate of the volume of waste to be disposed;(iv) The location of the site where the waste will be disposed; and(v) Results of waste characterization performed in accordance with 06-096 CMR ch. 405, section 6. (2)Access to Facility Sites. Access to a facility site must be controlled so that the public is not exposed to potential health and safety hazards. The operator shall provide suitable barriers, fencing and gates as needed to limit unauthorized persons from access. No access is permitted except when an attendant is on duty. (a) The operator shall prominently post the hours of operation and other limitations and conditions of access at the entrance to the landfill.(b) The operator shall provide well maintained access roads within the facility site. An access road into a cell of a landfill must be constructed and maintained to prevent the migration of leachate outside the cell.(c) Landfills must implement a road maintenance program to prevent the accumulation of dust, mud or wastes from the facility on access, public or private roads. An approved tire washing facility may also be used at a landfill in addition to a road maintenance program.(d) The operator shall post appropriate signs or other means to indicate clearly where solid waste is to be unloaded and where separate waste handling areas are located within the facility site.(3)Open Burning of Brush and Wood from Demolition Debris. Open burning of solid waste other than wood waste and painted wood, is prohibited at all landfills. All burning must be confined to a burn area approved by the Department. Wood that has been treated may not be burned. Other wastes, such as tires or waste oil, may not be used to start or maintain a burn. Burning must be done in conformance with the requirements of 06-096 CMR ch. 402, section 4(I).(4)Hot Loads. The operator shall provide a separate area for the placement of hot loads. The hot load area must be located away from vegetation and not in a location previously or currently used for disposal. Hot loads must be extinguished immediately upon dumping or spread in a thin layer to cool. Once cooled, the waste must be placed in the active portion of the landfill. Hot loads must not be placed near monitoring wells or surface water monitoring points. The operator of a landfill for the disposal of special wastes which may generate heat upon hydration shall place such wastes in an area within the active portion of the solid waste boundary, but discrete from the area where other wastes are currently being placed.
(5)Set-backs and Buffer Strips. The set-backs and buffer strips approved by the Department must be maintained.(6)Cell Development Plan. Within the limitations of the approved design for each landfill, operations manuals must include a cell development plan to meet the design standard of section 2(D)(6) and 2(F)(7). The plan must consist of a conceptual plan for the life of the landfill and the detailed plan for the current two year period as approved as part of the application or most recent annual report, whichever is applicable.(7)Compaction. For all landfills waste must be compacted once per operating day and more often as necessary unless otherwise approved by the Department. Waste must be compacted before the placement of cover material. From December 16 through March 31 in the southern zone and from November 16 through April 30 in the northern zone, solid waste may be deposited at a landfill without compaction or cover if the total lift height during this period does not exceed 12 feet and the total horizontal area covered with waste does not exceed 30,000 square feet. The Department may require daily cover during these time periods if site-specific conditions indicate it is needed.
NOTE: Northern zone and southern zone are defined in 06-096 CMR ch. 400, section 1.
(8)Cover. For all special waste and municipal solid waste landfills the cover material placement criteria are as follows: (a) Daily cover is required, except that daily cover is not required to be placed on pulp and paper mill sludge. A coarse soil material, such as sand or gravel, for secure landfills and a soil material for non-secure landfills must be placed and compacted to a minimum depth of 6 inches in thickness over all exposed waste at the end of each day of operation to completely and effectively cover the solid waste. Other materials or wastes may be proposed as alternative daily cover by a landfill owner or operator for approval by the Department. Use of residues from the processing of construction and demolition debris will be considered only at a landfill with a Department-approved active gas collection and control system. Alternative daily cover proposals must meet the following standards and include the following submission requirements: (i) The alternative daily cover must perform as an acceptable substitute for the soil material it is replacing, i.e. it must be able to control nuisance odor, dust, litter and vectors;(ii) The alternative daily cover must not exceed 9" in depth after compaction;(iii) The alternative daily cover proposal must consider and evaluate impacts on gas quantity and quality from application of the material;(iv) Unless the material proposed as an alternative daily cover has no odor or potential to create a nuisance odor, the submittal must include an odor management plan that includes provisions for the prevention and control of nuisance odor during routine operations, and a process for responding to any odor complaints received; and(v) Use of the alternative daily cover must cease if the Department determines its use causes a nuisance odor or negatively impacts the performance of the facility's active gas collection and control system. (b) Where final grade has been reached or on areas where disposal will not take place within the next 6 months, intermediate cover must be placed within 30 days after cessation of disposal, or as soon as weather conditions allow. Intermediate cover must remain in place in accordance with the requirements of the approved cell development plan. Intermediate cover must consist of 18" of soil or a geosynthetic cover material with a minimum thickness of 20 mils. The soil must be a clay or well-graded till with a minimum of 35% fines and no stones larger than 4 inches. It must be placed and compacted in at least two lifts. Other cover systems or wastes may be proposed by a landfill owner or operator for approval by the Department. Intermediate cover must completely and effectively cover the solid waste and be graded to limit infiltration and promote runoff. If soil is used these areas must be seeded and mulched to prevent erosion. Within the limitations of the approved design for each landfill, surface water run-off must be directed off of the landfill site. The intermediate cover must be removed before any further landfilling may occur in areas where cover has previously been placed.
The soil component of the intermediate cover may be considered part of the final cover system if the soil and its placement meet the design standards and construction requirements of section 5. Owner/operators must include these standards and requirements in the operations manual for installation of a phased final cover system as approved by the Department.
NOTE: Construction packages prepared to implement this requirement do not need to be included in the Operations Manual.
(c) For owners/operators approved to construct a phased final cover system throughout the operational life of the landfill, the phased final cover system must be constructed and documented in accordance with the approved plans and specifications. A phased final cover system documented to have been constructed in accordance with the approved plans and specifications will be accepted as the cover system element of final closure provided that the facility is not posing an unreasonable risk to public health or the environment at the time of final closure. (9)Stormwater Management and Erosion Control. The operator shall provide for erosion and sedimentation control in compliance with an approved erosion and sedimentation control plan that meets the standards and submission requirements of 06-096 CMR ch. 400, section 4(J). The operator shall also provide for stormwater management that is in compliance with an approved stormwater management plan that meets the standards and submission requirements of 06-096 CMR ch. 400, section 4(M). Erosion and sedimentation control structures and stormwater management structures shall be maintained on a routine basis.(10)Leachate Management. The operator must implement a leachate management plan in accordance with a Department approved plan or license, and must provide for maintenance and monitoring of the leachate collection, transport and storage systems. Contingency service contracts and/or letters of intent for leachate transport and disposal must be maintained throughout the operation and post-closure periods of each secure landfill. Contracts or letters of intent are not required when the leachate will be transported and treated by the facility owner.
For facilities that have a leak detection and removal system, action leakage rates and a response action plan must be incorporated into the operations plan. The response action plan must be implemented in the event that the action leakage rate(s) is/are exceeded.
(11)Landfill Gas(a) For a new landfill or an expansion to an existing landfill, the operator shall install, maintain, and monitor the gas collection or venting system for the landfill proposed in the Gas Management Assessment required in section 2(F)(6) of this Chapter, and as approved by the Department. For an existing landfill, the operator shall maintain and monitor the gas collection or venting system approved in the landfill's current license, if applicable. (b) The operator shall implement a quarterly methane gas monitoring program to verify the concentration of explosive gases generated by the landfill. The monitoring program must be based upon the soil, waste characteristics, hydrogeologic and hydraulic conditions at and surrounding the landfill, and the location of facility site structures and property boundaries.
(c) Immediately upon detection of explosive gas levels exceeding twenty-five percent (25%) of the lower explosive limit for the gases in the landfill structures, (excluding the gas control or recovery system components) or one hundred percent (100%) of the lower explosive limit for the gases at the property boundary, the operator shall take all steps necessary to protect human health and shall notify the Department of the occurrence and the protective steps that were taken. (i) The operator shall immediately record the methane levels, time of Department notification, and the protective steps that were taken.(ii) Within 60 days of detection, the operator shall implement a remediation plan to control the release of gases. This plan must be submitted to the Department, and must describe the nature and extent of the problem and the proposed remedy. The plan must be included in the operating record for the landfill.(d) The operator shall implement a gas monitoring program for gases other than methane as applicable to the facility depending upon the wastes being disposed of.(12)Inspections. The operator must provide for facility inspections on a regular basis, document the results of the inspections using the forms in the operations manual, and include a summary of the inspection results in the annual report required by section 4 (D). Items to be included in these inspections, an inspection schedule, and reporting forms must be provided in the operating manual. The inspection reports shall be kept on file at the landfill for a three year period and shall be available for Department inspection upon request. Provisions must be made in the inspection program to demonstrate that non-conforming inspection items have been brought into conformance with the applicable operating requirements, including documentation of repairs. As applicable, the inspection program must be sufficient to document:(a) The liner system is performing as designed; (b) The leachate management systems are performing as designed;(c) The gas management system is performing as designed;(d) The erosion and sedimentation control measures are performing as designed, and there is no noticeable erosion of the cover systems;(e) The stormwater management system is performing as designed;(f) The waste and cover system(s) grades and placement are in accordance with the approved cell development plan; and(g) Any deviations from the approved plans and specifications. Leachate collection, detection, and transport systems must be inspected on at least an annual basis.
