SUBPART A: GENERAL PROVISIONS

 

Section 220.100  Purpose

 

This Part contains emission control requirements for municipal solid waste (MSW) landfills in accordance with section 111(d) and subpart B of the Clean Air Act.

 

Section 220.110  Definitions

 

The definitions in this Section apply only to the provisions of this Part. Unless otherwise defined herein and unless a different meaning of a term is clear from its context, the definitions of terms used in this Part shall have the meanings specified by 35 Ill. Adm. Code 201.102, 211, and 810.103.

 

            "Active collection system" means a gas collection system that uses gas mover equipment.

 

            "Active landfill" means a landfill in which solid waste is being placed or a landfill that is planning to accept waste in the future.

 

            "Commercial waste" means all types of solid waste generated by stores, offices, restaurants, warehouses, and other nonmanufacturing activities, excluding household and industrial wastes.

 

            "Controlled landfill" means any landfill at which collection and control systems are required under this Part as a result of the NMOC emission rate. The landfill is considered controlled at the time an application for a construction permit for a collection and control system is submitted to the Agency in compliance with Sections 220.220 and 220.230 of this Part.

 

            "Design capacity" means the maximum amount of solid waste a landfill can accept, as indicated in terms of volume or mass, as specified in the permit(s) issued pursuant to Section 21(d) of the Act for the source plus any in-place waste not accounted for in the permit(s); if no design capacity is specified in a permit, then the design capacity shall be calculated using good engineering practices; or if the landfill is closed pursuant to the applicable regulations in 35 Ill. Adm. Code.Subtitle G, the actual capacity specified in the closure plan.  If the owner or operator chooses to convert the design capacity from volume to mass or from mass to volume to demonstrate its design capacity is less than 2.5 million Mg or 2.5 million m³, the calculation must include a site-specific density, which must be recalculated annually.

 

            "Disposal facility" means all contiguous land and structures, and improvements on the land used for the disposal of solid waste.  Portions of the disposal facility may be separated by access roads.

 

            "Emission rate cutoff" means the threshold annual emission rate to which a landfill compares its estimated emission rate to determine if control under this Part is required.

 

            "Enclosed combustor" means an enclosed firebox.  Examples include, but are not limited to, an enclosed flare, a boiler, and an internal combustion engine.

 

            "Flare" means an open combustor without enclosure or shroud.

 

            "Gas mover equipment" means the equipment (i.e., fan, blower, compressor) used to transport landfill gas through the header system.

 

            "Household waste" means any solid waste (including garbage, trash, and sanitary waste in septic tanks) derived from households (including, but not limited to, single and multiple residences, hotels and motels, bunkhouses, ranger stations, crew quarters, campgrounds, picnic grounds, and day-use recreation areas).  (Section 3.89 of the Act)

 

            "Inactive landfill" means a landfill in which solid waste is no longer being placed, and that is no longer permitted to accept waste under Section 21 of the Act or has a federally enforceable permit condition prohibiting the acceptance of additional waste.  If an inactive landfill is subsequently permitted to accept additional waste and additional solid waste is placed in the landfill, the landfill is no longer inactive.

 

            "Industrial waste" means solid waste generated by manufacturing or industrial processes that is not a hazardous waste regulated under Subtitle C of RCRA, 40 CFR 264 and 265.  Such waste may include, but is not limited to, waste resulting from the following manufacturing processes: electric power generation; fertilizer/agricultural chemicals; food and related products/by-products; inorganic chemicals; iron and steel manufacturing; leather and leather products; nonferrous metals manufacturing/foundries; organic chemicals; plastics and resins manufacturing; pulp and paper industry; rubber and miscellaneous plastic products; stone, glass, clay, and concrete products; textile manufacturing; transportation equipment; and water treatment. This term does not include mining waste or oil and gas waste.

 

            "Interior well" means any well or similar collection component located inside the perimeter of the landfill. A perimeter well located outside the landfilled waste is not an interior well.

 

            "Landfill" means an area of land or an excavation in which wastes are placed for permanent disposal, and that is not a land application unit, surface impoundment, or an underground injection well.  For the purposes of this Part, landfills include waste piles.

 

            "Lateral expansion" means a horizontal expansion of the waste boundaries of an existing MSW landfill.  A lateral expansion is not a modification for the purposes of filing an amended design capacity report pursuant to Section 220.210(a) of this Part, unless it results in an increase in the design capacity of the landfill.

 

            "Modification" means an increase in the permitted volume design capacity of the landfill by either horizontal or vertical expansion.

 

            "Municipal solid waste (MSW)" means household waste.

 

            "Municipal solid waste (MSW) landfill" means an entire disposal facility or landfill in a contiguous geographical space where household waste is placed in or on land.  An MSW landfill may also receive other types of RCRA Subtitle D wastes such as commercial solid waste, nonhazardous sludge, conditionally exempt small quantity generator waste, and industrial solid waste.  Portions of an MSW landfill may be separated by access roads.  An MSW landfill may be publicly or privately owned or operated.

 

            "Municipal solid waste (MSW) landfill emissions" means gas generated by decomposition of organic waste deposited in an MSW landfill or derived from the evolution of organic compounds in the waste.

 

            "Nondegradable waste" means any waste that does not decompose through chemical breakdown or microbiological activity.  Examples include, but are not limited to, concrete, municipal waste combustor ash, and metals.

 

            "Nonmethane organic compounds (NMOC)" means nonmethane organic compounds, as measured according to the provisions of Section 220.260 of this Part.

 

            "Passive collection system" means a gas collection system that uses solely positive pressure within the landfill to move the gas rather than using gas mover equipment.

 

            "Putrescible waste" means a solid waste that contains organic matter capable of being decomposed by microorganisms so as to cause a malodor, gases, or other offensive conditions, or which is capable of providing food for birds and vectors. Putrescible wastes may form a contaminated leachate from microbiological degradation, chemical processes, and physical processes. Putrescible waste includes, but is not limited to, garbage, offal, dead animals, general household waste, and commercial waste.  All solid wastes that do not meet the definitions of inert or chemical wastes shall be considered putrescible wastes.

 

            "Sludge" means any solid, semisolid, or liquid waste generated from a municipal, commercial, or industrial wastewater treatment plant, water supply treatment plant, or air pollution control facility, exclusive of the treated effluent from a wastewater treatment plant.

 

            "Solid waste" means a waste that is defined as an inert waste, as a putrescible waste, as a chemical waste or as a special waste, and which is also not defined as a hazardous waste pursuant to 35 Ill. Adm. Code 721.

 

            "Sufficient density" means any number, spacing, and combination of collection system components, including vertical wells, horizontal collectors, and surface collectors, necessary to maintain emission and migration control as determined by measures of performance set forth in this Part.

 

            "Sufficient extraction rate" means a rate sufficient to maintain a negative pressure at all wellheads in the collection system without causing air infiltration, including any wellheads connected to the system as a result of expansion or excess surface emissions, for the life of the blower.

5)         Collects and treats gas in accordance with the applicable requirements of 35 Ill. Adm. Code.Subtitle G.

 

b)         Active Collection Systems:

 

1)         Active collection wells, horizontal collectors, surface collectors, or other extraction devices shall be sited at a sufficient density throughout all gas producing areas using the following procedures:

 

A)        The collection devices within the interior and along the perimeter areas shall be designed to achieve comprehensive control of surface gas emissions.

 

B)        The sites for gas collection devices, as determined in subsection (b)(1)(A) of this Section, shall address landfill gas migration issues and augmentation of the collection system through the use of active or passive systems at the landfill perimeter or exterior.

 

C)        Collect gas at a sufficient extraction rate, as defined at Section 220.110 of this Part.

 

D)        The placement of gas collection devices determined in subsection (b)(1)(A) of this Section shall control all gas producing areas, except as provided by this subsection (b)(1)(D).

 

i)          Any segregated area of asbestos or nondegradable material may be excluded from collection, if documented as provided under Section 220.280(f)(3) of this Subpart.  The documentation shall provide the nature, date of deposition, location and amount of asbestos or nondegradable material deposited in the area, and shall be provided to the Agency upon request.

 

ii)         Any nonproductive area of the landfill may be excluded from control provided that the total of all excluded areas can be shown to contribute less than 1 percent of the total amount of NMOC emissions from the landfill. The amount, location, and age of the material shall be documented and provided to the Agency upon request.  A separate NMOC emissions estimate shall be made for each section proposed for exclusion, and the sum of all such sections shall be compared to the NMOC emissions estimate for the entire landfill, as calculated pursuant to Section 220.260 of this Subpart.  Emissions from each section shall be computed using the following equation:

 

Qi

=

2kLoMi(e-kti)(CNMOC)(3.6 x 10-9)

 

            where:

 

Qi	=	NMOC emission rate from the ith section, Mg/yr
k	=	methane generation rate constant, yr-1
Lo	=	methane generation potential, m3 per Mg solid waste
Mi	=	mass of degradable solid waste in the ith section, years
ti	=	age of the solid waste in the ith section, years
CNMOC	=	concentration of NMOC, ppmv
3.6x10-9	=	Conversion factor

 

            The values for k and C^NMOC determined in field testing shall be used, if field testing has been performed in determining the NMOC emission rate or the radii of influence (the distance from the well center to a point in the landfill where the pressure gradient applied by the blower or compressor approaches zero).  If field testing has not been performed, the default values for k, L_o, and C_NMOC provided in Section 220.260(a)(1) of this Subpart shall be used.  The mass of nondegradable solid waste contained within the given section may be subtracted from the total mass of the section when estimating emissions, provided the nature, location, age and amount of the nondegradable material is documented.

 

2)         The gas collection devices shall be constructed using the following equipment or procedures:

 

A)        The landfill gas extraction components shall be constructed of polyvinyl chloride (PVC), high density polyethylene (HDPE) pipe, fiberglass, stainless steel, or other nonporous corrosion resistant material of suitable dimensions to convey projected amounts of gases; withstand installation, static, and settlement forces; and withstand planned overburden or traffic loads.  The collection system shall extend as necessary to comply with emission and migration standards.  Collection devices, such as wells and horizontal collectors, shall be perforated to allow gas entry without head loss sufficient to impair performance across the intended extent of control. Perforations shall be situated with regard to the need to prevent excessive air infiltration.

 

B)        Vertical wells shall be placed so as not to endanger underlying liners and shall address the occurrence of water within the landfill.  Holes and trenches constructed for piped wells and horizontal collectors shall be of sufficient cross-section so as to allow for their proper construction and completion including, for example, centering of pipes and placement of gravel backfill. Collection devices shall be designed so as not to allow indirect short circuiting of air into the cover, refuse into the collection system or gas into the air.  Any gravel used around pipe perforations should be of a dimension so as not to penetrate or block perforations.

 

C)        Collection devices may be connected to the collection header pipes below or above the landfill surface.  The connector assembly shall include a positive closing throttle valve, any necessary seals and couplings, access couplings and at least one sampling port.  The collection devices shall be constructed of PVC, HDPE, fiberglass, stainless steel, or other nonporous material of suitable thickness.

 

3)         The landfill gas shall be conveyed to a gas control system through the collection header pipe(s).  The gas mover equipment shall be sized to handle the maximum gas generation flow rate expected for the period of intended use pursuant to Section 220.250(h) of this Subpart using the following procedures:

 

A)        For existing gas collection systems, the flow data shall be used to project the maximum flow rate.  If no flow data exists, the procedures in subsection (b)(3)(B) of this Section shall be used.

 

B)        For new gas collection systems, the maximum flow rate shall be in accordance with Section 220.240(a) of this Subpart.

 

c)         Passive Collection Systems:

 

1)         A passive collection system shall be installed with liners on the bottom and all sides in all areas in which gas is to be collected.  The liners shall meet all requirements specified in 35 Ill. Adm. Code 811.306.

 

2)         The collection and control system shall either conform with the specifications for active collection systems in subsection (a) of this Section or the owner or operator must obtain the Agency's approval for alternate provisions as provided for in subsection (d) of this Section.

 

d)         Alternate Collection Systems:

 

            An owner or operator seeking to install an alternate gas collection system shall demonstrate to the Agency that such collection system is capable of capturing the maximum expected gas flow rate from the entire area of the MSW landfill, for the period required in Section 220.250(h) of this Subpart, as calculated pursuant to Section 220.240(a) of this Subpart, and in an equivalent manner to that required by this Section.  Any alternate gas collection system must be approved by the Agency.  Such alternate shall be effective only when included in a federally enforceable permit or approved as a SIP revision.  The alternate shall include any alternate procedures for collection, control, compliance, monitoring, operation, testing, reporting, and recordkeeping that are appropriate.

 

e)         Alternate Emissions Standard:

 

            Pursuant to Section 28.1 of the Act [415 ILCS 5/28.1], and in accordance with 35 Ill. Adm. Code 106, Subpart G, provisions for adjusted standards, adjusted standards for alternate emissions standards or alternate emissions standards with an alternate compliance schedule shall be granted by the Board, to the extent consistent with federal law.  An owner or operator seeking an alternate emissions standard or an alternate emissions standard with an alternate compliance schedule must demonstrate to the Board that, with respect to the MSW landfill, the control requirements meet one or more of the criteria listed in this subsection (e) pursuant to 40 CFR 60.24(f). Any such request must be approved by the Board.  Such alternate shall be effective only when included in a federally enforceable permit or approved as a SIP revision. Any alternate shall include any procedures for collection, control, compliance, monitoring, operation, testing, reporting and recordkeeping that are appropriate and a demonstration that the control requirements, as contained in this Subpart, as they apply to the MSW landfill, meet one or more of the following criteria:

 

1)         Unreasonable cost of control resulting from plant age, location, or basic process design;

 

2)         Physical impossibility of installing necessary control equipment; or

f)         Gas control systems must be operated in accordance with a permit issued pursuant to the applicable requirements of 35 Ill. Adm. Code.Subtitle G.

 

Section 220.240  Compliance Procedures for Gas Collection Systems

 

a)         The methods specified in subsections (a)(1) through (a)(6) of this Section shall be used to determine whether the gas collection system is in compliance with Section 220.220 of this Subpart.

 

1)         To calculate the maximum expected gas generation flow rate from the MSW landfill, one of the following equations shall be used.  The k and L_o kinetic factors shall be those published in the Compilation of Air Pollutant Emission Factors (AP-42) incorporated by reference in Section 220.130 of this Part, or other site-specific emission factors approved by the Agency.  If k has been determined as specified in Section 220.260(a)(4) of this Subpart, the value of k determined from the test shall be used.  A value of no more than 15 years shall be used for the intended use period of the gas mover equipment, the variable t.  The active life of the landfill is the age of the landfill plus the estimated number of years until closure.

 

A)        For sites with unknown year-to-year solid waste acceptance rate:

 

Qm

=

2LoR(e-kc-e-kt)

 

where:

 

Qm	=	maximum expected gas generation flow rate, m3/yr
Lo	=	methane generation potential, m3 per Mg solid waste
R	=	average annual acceptance rate, Mg/yr
k	=	methane generation rate constant,  yr-1
t	=	age in years of the landfill at equipment installation plus time the owner or operator intends to use the gas mover equipment or active life of the landfill, whichever is less.  If the equipment is installed after closure, t in years is the age of the landfill at installation
c	=	time since closure, years (for an active landfill c = 0 and e-kc=1)

 

B)        For sites with known year-to-year solid waste acceptance rates:

 

Qm	=	n	2kLoMi(e-kti)
		Σ
		i=1

 

where:

 

Qm	=	maximum expected gas generation flow rate, m3/yr
k	=	methane generation rate constant, yr-1
Lo	=	methane generation potential, m3 per Mg solid waste
Mi	=	mass of solid waste in the ith section, Mg
ti	=	age of the ith section, yr

 

C)        If a collection and control system has been installed, actual flow data may be used to project the maximum expected gas generation flow rate instead of, or in conjunction with, the equations in subsections (a)(1)(A) and (a)(1)(B) of this Section.  If the landfill is still accepting waste, the actual measured flow data will not equal the maximum expected gas generation rate, so calculations made using the equations in subsection (a)(1)(A) or (a)(1)(B) of this Section or other methods shall be used to predict the maximum gas generation rate over the intended period of use of the gas control system equipment.

 

2)         For the purpose of determining the sufficient number of gas collectors, the owner or operator shall design a system of vertical wells, horizontal collectors, or other type of collection device, capable of controlling and extracting gas from all portions of the landfill sufficient to meet the operational and performance standards of Sections 220.220 through 220.250. Such design must be approved by the Agency as part of an air construction permit or a CAAPP permit, if the gas collection system was installed prior to July 31, 1998.

 

3)         For the purpose of demonstrating whether the gas collection system flow rate of an active collection system is sufficient, the owner or operator shall measure gauge pressure in the gas collection header at each individual well monthly.  If positive pressure exists, action shall be initiated to correct the exceedence within 5 calendar days, except for the three conditions allowed under Section 220.250(b) of this Subpart.  If negative pressure cannot be achieved without excess air infiltration within 15 calendar days after the first measurement, the gas collection system shall be expanded to correct the exceedence within 120 days after the initial measurement of positive pressure. Any attempted corrective measure must not cause exceedences of other operational or performance standards. An alternate timeline for correcting the exceedence may be submitted to the Agency for approval.

 

4)         Owners or operators are not required to expand the system, as required in subsection (a)(3) of this Section, during the first 180 days after gas collection system startup.

6)         An owner or operator using a collection system that does not conform to the specifications provided in Section 220.220(b) or (c) of this Subpart shall provide information satisfactory to the Agency, as specified in Section 220.220(d) of this Subpart, demonstrating that off-site migration is being controlled.

 

b)         To comply with the operational standards in Section 220.250(a) of this Subpart, each owner or operator of a controlled landfill shall install each well or design component as specified in a construction permit issued by the Agency.  Each well shall be installed no later than 60 days after the date on which the initial solid waste has been in place for a period of:

 

1)         5 years or more if active; or

 

2)         2 years or more if closed or at final grade.

 

c)         The following procedures shall be used for compliance with the surface methane operational standard as provided in Section 220.250(d) of this Subpart.

 

1)         After installation of the collection system, the owner or operator shall monitor surface concentrations of methane along the entire perimeter of the collection area and along a pattern that traverses the landfill at 30-meter intervals (or site-specific established spacing) for each collection area on a quarterly basis using an organic vapor analyzer, flame ionization detector, or other portable monitor meeting the specifications provided in subsection (d) of this Section.

C)        If the remonitoring of the location shows a second exceedence, additional corrective action shall be taken and the location shall be monitored again within 10 days after the second exceedence.  If the remonitoring shows a third exceedence for the same location, the action specified in subsection (c)(4)(E) of this Section shall be taken.  No further monitoring of that location is required until the action specified in subsection (c)(4)(E) of this Section has been taken.

 

D)        If the remonitoring of the location does not show an exceedence, as specified by subsection (c)(4)(B) or (c)(4)(C), the location shall be remonitored 1 month from the initial exceedence.  If the 1 month remonitoring shows a concentration less than 500 ppm above background, no further monitoring of that location is required until the next quarterly monitoring period.  If the 1 month remonitoring shows an exceedence, the actions specified in subsection (c)(4)(C) or (c)(4)(E) of this Section, as appropriate, shall be taken.

 

E)        For any location where there are three monitored exceedences within a quarterly period, a new well or other collection device shall be installed within 120 calendar days after the initial exceedence.  An alternate remedy to the exceedence, such as upgrading the blower, header pipes, or control device, and a corresponding timeline for installation may be submitted to the Agency for approval.

 

5)         The owner or operator shall implement a program to monitor for cover integrity and implement cover repairs as necessary on a monthly basis.

 

d)         The following instrumentation specifications and procedures for surface emission monitoring devices apply to the monitoring required by subsection (c) of this Section:

Section 220.250  Operational Standards for Collection and Control Systems

 

Each owner or operator of an MSW landfill with a gas collection and control system shall:

 

a)         Operate the collection system such that gas is collected from each area, cell, or group of cells in the MSW landfill in which the initial solid waste has been in place for:

 

1)         5 years or more if active; or

 

2)         2 years or more if closed or at final grade.

 

b)         Operate the collection system with negative pressure at each wellhead except under the following conditions:

 

1)         A fire or increased well temperature.  The owner or operator shall record instances when positive pressure occurs in efforts to avoid a fire.  These records shall be submitted with the annual reports as provided in Section 220.280(e)(1) of this Subpart.

 

2)         Use of a geomembrane or synthetic cover.  The owner or operator shall develop pressure limits associated with such a cover that must be approved by the Agency.

 

3)         A decommissioned well. A well may experience a static positive pressure after shut down to accommodate for declining flows.  All design changes shall be approved by the Agency.

 

c)         Operate each interior wellhead in the collection system with a landfill gas temperature less than 55°C (131°F) and with either a nitrogen level less than 20 percent or an oxygen level less than 5 percent.  The owner or operator may establish a higher operating temperature, nitrogen, or oxygen value at a particular well.  A higher operating value demonstration that provides supporting data to show that the elevated parameter does not cause fires or significantly inhibit anaerobic decomposition by killing methagens must be approved by the Agency before such higher operating value may be used. Operating values shall be determined as follows:

 

1)         The nitrogen level shall be determined using Method 3C, Appendix A, 40 CFR 60, incorporated by reference in Section 220.130 of this Part.

 

2)         The oxygen level shall be determined by an oxygen meter using Method 3A, Appendix A, 40 CFR 60, incorporated by reference in Section 220.130 of this Part, except that:

 

A)        The span shall be set so that the regulatory limit is between 20 and 50 percent of the span;

 

B)        A data recorder is not required;

 

C)        Only two calibration gases are required, a zero and span, and ambient air may be used as the span;

 

D)        A calibration error check is not required; and

 

E)        The allowable sample bias, zero drift, and calibration drift are plus or minus 10 percent.

 

d)         Operate the collection system so that the methane concentration is less than 500 ppm above background at the surface of the landfill.  To determine if this level is exceeded, the owner or operator shall conduct surface testing around the perimeter of the collection area and along a pattern that traverses the landfill at 30-meter intervals and where visual observations indicate elevated concentrations of landfill gas, such as distressed vegetation and cracks or seeps in the cover.  An initial surface monitoring design plan shall be developed and included as part of the operating permit application (e.g., a CAAPP permit application) that includes a topographical map with the monitoring route and the rationale for any site-specific deviations from the 30-meter intervals.  Areas with steep slopes or other dangerous areas may be excluded from the surface testing.  The monitoring plan shall be updated as necessary. Updated copies must be sent to the Agency and kept on-site at the MSW landfill.

 

e)         Operate the gas collection and control system such that all collected gases are vented to a control system designed and operated in compliance with Sections 220.230, 220.250, and 220.270 of this Subpart.  In the event the collection or control system is inoperable, the gas mover system shall be shut down and all valves in the collection and control system contributing to venting of the gas to the atmosphere shall be closed within 1 hour.

 

f)         Operate the gas collection and control or treatment system at all times, except during shutdown or malfunction, provided that the duration of start-up, shutdown, or malfunction must not exceed 5 days for collection systems and must not exceed 1 hour for treatment or control devices.

 

g)         If monitoring demonstrates that the operational requirements in subsection (b), (c), or (d) of this Section are not met, take corrective action as specified in Section 220.240(a)(3), (a)(5), or (c)(4) of this Subpart.  If such corrective actions are taken as specified in Section 220.240(a)(3), (a)(5), or (c)(4) of this Subpart, the monitored exceedence is not a violation of the operational requirements in this Section.

 

h)         The collection and control system may be capped or removed provided:

 

1)         The landfill is no longer accepting solid waste;

 

2)         A system removal report has been submitted to the Agency, as provided in Section 220.280(d) of this Subpart;

 

3)         The collection and control system has been operating a minimum of 15 years;

 

4)         The calculated NMOC gas produced by the landfill is less than 50 Mg/yr on three successive test dates, pursuant to the procedures specified in Section 220.260(b) of this Subpart. The test dates shall be no less than 90 days apart, and no more than 180 days apart; and

 

5)         The system is not required to satisfy any applicable requirement of 35 Ill. Adm. Code.Subtitle G.

 

Section 220.260   Test Methods and Procedures

 

a)         The landfill owner or operator shall calculate the NMOC emission rate using the equation provided in either subsection (a)(1)(A) or subsection (a)(1)(B) of this Section and make a determination that the emission rate is less than 50 Mg/yr, pursuant to subsection (a)(2), (a)(3), (a)(4), or (e), or install a gas collection and control system pursuant to Sections 220.220 and 220.230 of this Subpart.  However, both equations may be used if the actual year-to-year solid waste acceptance rate is known pursuant to subsection (a)(1)(A) of this Section, for part of the life of the landfill and the actual year-to-year solid waste acceptance rate is unknown, pursuant to subsection (a)(1)(B) of this Section, for part of the life of the landfill.  If the NMOC emission rate calculated in this subsection is less than 50 Mg/yr, then the landfill owner shall submit an emission rate report as provided in Section 220.280(b) of this Subpart, and shall recalculate the NMOC mass emission rate as required under Section 220.210(c) of this Subpart.

 

1)         The values to be used in both equations are 0.05/yr for k, 170 m³ per Mg for L_o, and 4,000 ppmv as hexane for the C_NMOC.

 

A)        The following equation shall be used if the actual year-to-year solid waste acceptance rate is known:

 

MNMOC	=	n	2kLo Mi(e-kti)(CNNMOC)(3.6x10-9)
		Σ
		i=1

 

            where:

 

MNMOC	=	Total NMOC emission rate from the landfill, Mg/yr
k	=	methane generation rate constant, yr-1
Lo	=	methane generation potential, m3 per Mg solid waste
Mi	=	mass of solid waste in the ith section, Mg
ti	=	age of solid waste in the ith section, years
CNMOC	=	concentration of NMOC, ppmv as hexane
3.6 x 10-9	=	conversion factor

 

            The mass of nondegradable solid waste may be subtracted from the total mass of solid waste in a particular section of the landfill when calculating the value for Mⁱ if documentation of the nature and amount of such wastes is maintained.

 

B)        The following equation shall be used if the actual year-to-year solid waste acceptance rate is unknown:

 

            M_NMOC = 2L_oR(e^-kc - e(^-kt))(C_NMOC)(3.6 x 10^-9)

 

            where:

 

MNMOC	=	Total NMOC emission rate from the landfill, Mg/yr
Lo	=	methane generation potential, m3 per Mg solid waste
R	=	average annual acceptance rate, Mg/yr
k	=	methane generation rate constant, year-1
t	=	age of landfill, years
CNMOC	=	concentration of NMOC, ppmv as hexane conversion factor
c	=	time since closure, years (for active landfill c = 0 and e-kc = 1)
3.6 x 10-9	=	conversion factor

 

            The mass of nondegradable solid waste may be subtracted from the average annual acceptance rate when calculating a value for R, if documentation of the nature and amount of such wastes is maintained.

 

2)         Tier 1.  The landfill owner or operator shall calculate the NMOC mass emission rate using the equations provided in subsection (a)(1)(A) or (a)(1)(B) of this Section. The owner or operator shall compare the calculated NMOC mass emission rate to the standard of 50 Mg/yr using the default values for the NMOC mass emission rate and the methane generation rate constant.

 

3)         Tier 2.  The landfill owner or operator shall calculate the NMOC mass emission rate using the equations provided in subsection (a)(1)(A) or (a)(1)(B) of this Section using the average NMOC concentration from the collected samples instead of the default value in the equations provided in subsection (a)(1) of this Section. The landfill owner or operator shall determine the NMOC concentration using the following sampling procedure:  The landfill owner or operator shall install at least 2 sample probes per hectare of landfill surface that has retained waste for at least 2 years.  If the landfill is larger than 25 hectares in area, only 50 samples are required. The sample probes should be located to avoid known areas of nondegradable solid waste.  The owner or operator shall collect and analyze one sample of landfill gas from each probe to determine the NMOC concentration using Method 25C or Method 18 of Appendix A, 40 CFR 60, incorporated by reference in Section 220.130 of this Part.  If using Method 18, the minimum list of compounds to be tested shall be those published in the Compilation of Air Pollutant Emission Factors (AP-42), incorporated by reference in Section 220.130 of this Part.  If composite sampling is used, equal volumes shall be taken from each sample probe.  If more than the required number of samples are taken, all samples shall be used in the analysis.  Divide the NMOC concentration from Method 25C by 6 to convert from C_NMOC as carbon to C_NMOC as hexane.  The owner or operator shall retest the site-specific NMOC concentration every 5 years using the methods specified in this Section.

 

4)         Tier 3.  The landfill owner or operator shall estimate the NMOC mass emission rate using equations in subsection (a)(1)(A) or (a)(1)(B) of this Section and using a site-specific methane generation rate constant k, and the site-specific NMOC concentration as determined in subsection (a)(3) of this Section instead of the default values provided in subsection (a)(1) of this Section.  The site-specific methane generation rate constant shall be determined using the procedures provided in Method 2E, Appendix A, 40 CFR 60, incorporated by reference in Section 220.130 of this Part.  The calculation of the methane generation rate constant is performed only once, and the value obtained is used in all subsequent annual NMOC emission rate calculations.  In addition, pursuant to subsection (a)(3) of this Section, the owner or operator shall retest the site-specific NMOC concentration every 5 years using the methods specified in that subsection.

 

b)         After the installation of a collection and control system in compliance with Sections 220.220 and 220.230 of this Subpart, the owner or operator shall calculate the NMOC emission rate for purposes of determining when the system can be removed as provided in Section 220.250(h) of this Subpart, using the following equation:

 

            M_NMOC = 1.89 x 10^-3 Q_LFG C_NMOC

 

            where:

 

MNMOC	=	mass emission rate of NMOC (Mg/yr)
QLFG	=	flow rate of landfill gas (m3/minute)
CNMOC	=	NMOC concentration (ppmv as hexane)

 

1)         The flow rate of landfill gas (Q_LFG) shall be determined by measuring the total landfill gas flow rate at the common header pipe that leads to the control device using a gas flow measuring device calibrated according to the provisions of Section 4 of Method 2E, Appendix A, 40 CFR 60, incorporated by reference in Section 220.130 of this Part.

 

2)         The average NMOC concentration (C_NMOC) shall be determined by collecting and analyzing landfill gas sampled from the common header pipe before the gas moving or condensate removal equipment using the procedures in Method 25C or Method 18, Appendix A, 40 CFR 60, incorporated by reference in Section 220.130 of this Part.  If using Method 18, the minimum list of compounds to be tested shall be those published in the Compilation of Air Pollutant Emission Factors (AP-42), incorporated by reference in Section 220.130 of this Part.  The sample location on the common header pipe shall be before any condensate removal or other gas refining units.  The landfill owner or operator shall divide the NMOC concentration from Method 25C by 6 to convert C_NMOC as carbon to C_NMOC as hexane.

 

c)         If the gas collection system complies with the provisions in Section 220.220 of this Subpart and is already installed, the owner or operator shall estimate the NMOC emission rate using the procedures provided in subsection (b) of this Section.  For areas of the landfill where the owner or operator has not been required to install a well yet, he/she may select an appropriate method from subsection (a) of this Section to estimate emissions.

 

d)         For the performance test required in Section 220.210(d)(2) of this Subpart, Method 25C or Method 18, Appendix A, 40 CFR 60, incorporated by reference in Section 220.130 of this Part, shall be used to determine compliance with 98 weight-percent efficiency or the 20 ppmv outlet concentration level, unless another method to demonstrate compliance has been approved by the Agency as provided by Section 220.230(d) of this Subpart.  If using Method 18, the minimum list of compounds to be tested shall be those published in the Compilation of Air Pollutant Emission Factors (AP-42), incorporated by reference in Section 220.130 of this Part.  The following equation shall be used to calculate efficiency:

 

            Control efficiency = (NMOC_in - NMOC_out)/(NMOC_in)

 

            where:

 

NMOCin	=	mass of NMOC entering control device
NMOCout	=	mass of NMOC exiting control device

 

e)         The owner or operator may use other methods to determine the NMOC concentration, site-specific k, or landfill gas flow rate, as an alternate to the methods required in subsection (a)(3) and (a)(4) of this Section, if the method has been approved by the Agency, as provided for in Section 220.220(d) or Section 220.230(d) of this Subpart.

 

f)         The owner or operator may use the procedures described in AP-42, Compilation of Air Pollutant Emission Factors, incorporated by reference in Section 220.130 of this Part, to estimate emissions pursuant to the annual emission report required in 35 Ill. Adm. Code 210.302(a).  The most recent values for k, L_o, and NMOC concentration reported in AP-42 shall be used to calculate emissions.  To determine applicability of or compliance with the requirements of this Part, the owner or operator must use the tiered emission estimates provided in subsections (a)(1) through (a)(4) of this Section.

 

g)         Testing:

 

1)         Upon a request by the Agency, the owner or operator of an MSW landfill shall at his own expense demonstrate compliance with the applicable requirements of this Subpart using the appropriate test method.

 

2)         An owner or operator planning to conduct a test to demonstrate compliance with this Subpart shall notify the Agency of that intent not less than 30 days before the planned initiation of the tests so that the Agency may observe the test.

 

Section 220.270  Monitoring of Operations

 

a)         Active gas collection systems.  Each owner or operator of an active gas collection system shall install a sampling port and a thermometer, other temperature measuring device, or an access port for temperature measurements at each wellhead and:

1)         A temperature monitoring device equipped with a continuous recorder and having a minimum accuracy of plus or minus 1 percent of the temperature being measured, expressed in degrees Celsius, or plus or minus 0.5°C, whichever is greater.  A temperature monitoring device is not required for boilers or process heaters with design heat input capacity greater than 44 MW.

 

2)         A device that records flow to or bypass of the control device.  The owner or operator shall either:

 

A)        Install, calibrate, and maintain a gas flow rate measuring device that shall record the flow to the control device every 15 minutes; or

 

B)        Secure the bypass line valve in the closed position with a car-seal or a lock-and-key type configuration.  A visual inspection of the seal or closure mechanism shall be performed at least once every month to ensure that the valve is maintained in the closed position and that the gas flow is not diverted through the bypass line.

 

c)         Open flare.   Each owner or operator of an open flare shall install, calibrate, maintain, and operate according to the manufacturer's specifications the following equipment:

 

1)         A heat sensing device, such as an ultraviolet beam sensor or thermocouple, at the pilot light or the flame itself to indicate the continuous presence of a flame.

 

2)         A device that records flow to or bypass of the flare.  The owner or operator shall either:

 

A)        Install, calibrate, and maintain a gas flow rate measuring device that shall record the flow to the control device at least every 15 minutes; or

d)         Each owner or operator seeking to install a collection or control system that does not meet the specifications in Section 220.220(b) or (c) of this Subpart, shall provide information satisfactory to the Agency as provided in Sections 220.220(d) and 220.230(d) of this Subpart, describing the design and operation of the collection system, the operating parameters that would indicate proper performance, and appropriate monitoring procedures.

 

e)         Each owner or operator shall monitor surface concentrations of methane according to the  instrument specifications and procedures provided in Section 220.240(c) and (d) of this Subpart.  Any inactive landfill that has no monitored exceedences of the operational standard in three consecutive quarterly monitoring periods must resume annual monitoring.  Any methane reading of 500 ppm or more above the background detected during the annual monitoring returns the monitoring frequency for that landfill to quarterly.

 

Section 220.280  Reporting Requirements

 

a)         Each owner and operator shall submit a design capacity report to the Agency.

 

1)         The initial design capacity report shall be submitted no later than October 29, 1998.

 

2)         The initial design capacity report shall contain the following information:

 

A)        A map or plot of the landfill providing the size and location of the landfill and identifying all areas where solid waste may be landfilled according to the provisions of the State or RCRA construction or operating permit.

 

B)        The maximum design capacity of the landfill. If the maximum design capacity is specified in a State construction or RCRA permit, a copy of the permit specifying the maximum design capacity of the landfill shall be provided.  If the maximum design capacity of the landfill is not specified in a permit, the maximum design capacity shall be calculated using good engineering practices.  The calculations shall be provided, along with the relevant parameters (e.g., depth of solid waste, solid waste acceptance rate, and compaction practices, as applicable), as part of the report.  The Agency may request other reasonable information as may be necessary to verify the maximum design capacity of the landfill.

 

3)         An amended design capacity report shall be submitted to the Agency providing notification of an increase in the design capacity of the landfill within 90 days after an increase in the maximum design capacity of the landfill to or above 2.5 million Mg and 2.5 million m³.  This increase in design capacity may result from an increase in the permitted volume or an increase in the density of the landfill as documented in the annual recalculation required in Section 220.290(f) of this Subpart.

 

b)         Each owner and operator with a total design capacity equal to or greater than 2.5 million Mg and 2.5 million m³ shall submit an NMOC emission rate report to the Agency initially and by June 1 annually thereafter, except as provided for in subsections (b)(1) and (b)(4) of this Section.  The Agency may request such additional information as may be necessary to verify the reported NMOC emission rate. The NMOC emission rate report shall contain an annual or 5-year estimate of the NMOC emission rate calculated using the formula and procedures in Section 220.260(a) of this Subpart, as applicable.  The annual NMOC emission rate report required by this subsection must be submitted with the annual emissions report required pursuant to 35 Ill. Adm. Code 201.302(a).

 

1)         The initial NMOC emission rate report may be combined with the initial design capacity report required in subsection (a) of this Section. The first NMOC emission report shall be filed with the Agency by October 29, 1998. Subsequent NMOC emission reports shall be filed with the Agency by June 1 of the subsequent year, except as provided for in subsection (b)(2) of this Section.

 

2)         Using Tier 1, if the estimated NMOC emission rate as reported in the annual report to the Agency is less than 50 Mg/yr in each of the next 5 consecutive years, the owner or operator may elect to submit an estimate of the NMOC emission rate for the next 5-year period in lieu of the annual report. This estimate shall include the current amount of solid waste in-place and the estimated waste acceptance rate for each year of the 5 years for which an NMOC emission rate is estimated.  All data and calculations upon which this estimate is based shall be provided to the Agency.  This estimate shall be revised at least once every 5 years.  If the actual waste acceptance rate exceeds the estimated waste acceptance rate in any year reported in the 5-year estimate, a revised 5-year estimate shall be submitted to the Agency.  The revised estimate shall cover the 5-year period beginning with the year in which the actual waste acceptance rate exceeded the estimated waste acceptance rate.

 

3)         The NMOC emission rate report shall include all the data, calculations, sample reports and measurements used to estimate the annual or 5-year emissions.

 

4)         All owners and operators of MSW landfills with a total design capacity of 2.5 million Mg and 2.5 million m³ are required to submit an annual emissions report pursuant to 35 Ill. Adm. Code 201.302(a).  MSW landfills that have installed a gas collection and control system that meets the requirements of this Subpart are not required to submit an annual NMOC emission rate report but are required to submit an annual emissions report pursuant to 35 Ill. Adm. Code 201.302(a). Further, owners or operators filing a 5-year estimate of NMOC emissions pursuant to subsection (b)(2) of this Section may use a 5-year estimate for NMOC, so long as they file an annual emission report and meet the requirements of subsection (b)(2) of this Section.
