Rule 3745-76-01 | Definitions.

• Effective: August 25, 2016
• Promulgated Under: 119.03

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see paragraph (B)(31) of this rule titled, "Referenced materials."]

(A) Terms used but not defined in this chapter have the meaning given them in the Clean Air Act and in rule 3745-15-01 of the Administrative Code.

(B) The following definitions shall apply exclusively to this chapter.

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

(2) "Active landfill" means a licensed and permitted landfill in which solid waste is being placed or a landfill that is planned to accept waste in the future.

(3) "Btu" means British thermal unit

(4) "Closed landfill" means a landfill in which solid waste is no longer being placed, and in which no additional solid wastes will be placed without first filing a notification of modification in accordance with 40 CFR 60.7(a)(4). Once a notification of modification has been filed, and additional solid waste is placed in the landfill, the landfill is no longer closed. .

(5) "Closure" means that point in time when a landfill becomes a closed landfill.

(6) "Commercial solid waste" means all types of solid waste generated by stores, offices, restaurants, ware-houses, and other non-manufacturing activities, excluding residential and industrial wastes.

(7) "Controlled landfill" means any landfill at which collection and control systems are required under this chapter as a result of the nonmethane organic compounds emission rate. The landfill is considered controlled at the time a collection and control system design plan is submitted in compliance with paragraph (B)(2)(a) of rule 3745-76-07 of the Administrative Code.

(8) "Design capacity" means the maximum amount of solid waste a landfill can accept, as indicated in terms of volume or mass in the most recent permit issued by the agency responsible for regulating the landfill, plus any in-place waste not accounted for in the most recent permit. 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 megagrams or 2.5 million cubic meters, the calculation must include a site specific density, which must be recalculated annually.

(9) "Disposal facility" means any contiguous land and structures, other appurtenances, and improvements on the land used for the disposal of solid waste.

(10) "Emission rate cutoff" means the threshold annual emission rate to which a landfill compares its estimated emission rate to determine if control under the regulation is required.

(11) "Enclosed combustor" means an enclosed firebox which maintains a relatively constant limited peak temperature generally using a limited supply of combustion air. An enclosed flare is considered an enclosed combustor.

(12) "Flare" means an open combustor without enclosure or shroud.

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

(14) "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).

(15) "Industrial solid waste" means solid waste generated by manufacturing or industrial processes that is not a hazardous waste regulated under Subtitle C of the Resource Conservation and Recovery Act, 40 CFR Part 264 and 40 CFR Part 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; non-ferrous 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 definition does not include mining waste or oil and gas waste.

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

(17) "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, injection well, or waste pile as those terms are defined under 40 CFR 257.2.

(18) "Lateral expansion" means a horizontal expansion of the waste boundaries of an existing MSW landfill. A lateral expansion is not a modification unless it results in an increase in the design capacity of the landfill.

(19) "Modification" means an increase in the permitted volume design capacity of the landfill by either horizontal or vertical expansion based on its permitted design capacity as of May 30, 1991. Modification does not occur until the owner or operator commences construction on the horizontal or vertical expansion.

(20) "Municipal solid waste" is a type of solid waste generated from community, commercial and agricultural operations, including but not limited to the following:

(a) Solid waste generated by community operations (including single and multiple-household residences, hotels, motels, bunkhouses, ranger stations, crew quarters, campgrouds, and day-use recreation areas;

(b) Solid waste generated by commercial operations (including stores, offices, restaurants, warehouses, and other non-manufacturing activities);

(c) Solid waste generated from agricultural operations (including single-family and commercial farms, greenhouses, and nurseries);

(d) Sludge from municipal, commercial, or industrial waste water treatment plants, water treatment plants, and air pollution control facilities that is co-disposed with other municipal solid waste in a sanitary landfill facility; and

(e) Fly ash and bottom ash generated from the incineration of municipal solid waste, provided the fly ash and bottom ash is not regulated as a hazardous waste.

(21) "Municipal solid waste landfill" or "MSW landfill" means an entire disposal facility 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 (40 CFR 257.2) 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. An MSW landfill may be a new MSW landfill, an existing MSW landfill, or a lateral expansion.

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

(23) "NMOC" means nonmethane organic compounds, as measured according to the provisions of rule 3745-76-09 of the Administrative Code.

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

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

(26) "PSD" means prevention of significant deterioration, as defined in 40 CFR 52.21, prevention of significant deterioration of air quality.

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

(28) "Solid waste" means any garbage, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded material, included solid, liquid, semisolid, or contained gaseous material resulting from industrial, commercial, mining, and agricultural operations, and from community activities, but does not include solid or dissolved material in domestic sewage, or solid or dissolved materials in irrigation return flows or industrial discharges that are point sources subject to permits under the national pollutant discharge elimination system or the United States nuclear regulatory commission.

(29) "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 chapter.

(30) "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.

Rule 3745-76-08 | Operational standards for collection and control systems.

• Effective: October 10, 2006
• Promulgated Under: 119.03

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see the last paragraph of rule 3745-76-01 of the Administrative Code titled "Incorporation by reference."]

Each owner or operator of an MSW landfill with a gas collection and control system used to comply with the provisions of paragraph (B)(2)(b) of rule 3745-76-07 of the Administrative Code 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 solid waste has been in place for :

(1) Five years or more if active; or

(2) Two 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 paragraph (F)(1) of rule 3745-76-12 of the Administrative Code;

(2) Use of a geomembrane or synthetic cover. The owner or operator shall develop acceptable pressure limits in the design plan;

(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 director;

(C) Operate each interior wellhead in the collection system with a landfill gas temperature less than fifty five degrees Celsius and with either a nitrogen level less than twenty percent or an oxygen level less than five per cent. The owner or operator may establish a higher operating temperature, nitrogen, or oxygen value at a particular well. A higher operating value demonstration shall show supporting data that the elevated parameter does not cause fires or significantly inhibit anaerobic decomposition by killing methanogens.

(1) The nitrogen level shall be determined using Method 3C of Appendix A of 40 CFR Part 60, unless an alternative test method is established as allowed by paragraph (B)(2)(a) of rule 3745-76-07 of the Administrative Code.

(2) Unless an alternative test method is established as allowed by paragraph (B)(2)(a) of rule 3745-76-07 of the Administrative Code, the oxygen shall be determined by an oxygen meter using Method 3A of Appendix A of 40 CFR Part 60 except that:

(a) The span shall be set so that the regulatory limit is between twenty and fifty per cent 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;

(e) The allowable sample bias, zero drift, and calibration drift are plus or minus ten per cent.

(D) Operate the collection system so that the methane concentration is less than five hundred parts per million 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 thirty meter intervals and where visual observations indicate elevated concentrations of landfill gas, such as distressed vegetation and cracks or seeps in the cover. The owner or operator may establish an alternative traversing pattern that ensures equivalent coverage. A surface monitoring design plan shall be developed that includes a topographical map with the monitoring route and the rationale for any site-specific deviations from the thirty meter intervals. Areas with steep slopes or other dangerous areas may be excluded from the surface testing.

(E) Operate the system such that all collected gases are vented to a control system designed and operated in compliance with paragraph (B)(2)(c) of rule 3745-76-07 of the Administrative Code. 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 one hour; and

(F) Operate the control or treatment system at all times when the collected gas is routed to the system.

(G) If monitoring demonstrates that the operational requirements in paragraph (B), (C), or (D) of this rule are not met, corrective action shall be taken as specified in paragraphs (A)(3) to (A)(5) of rule 3745-76-10 of the Administrative Code or paragraph (C) of rule 3745-76-10 of the Administrative Code. If corrective actions are taken as specified in rule 3745-76-10 of the Administrative Code, the monitored exceedance is not a violation of the operational requirements in this rule.

Rule 3745-76-09 | Test methods and procedures.

• Effective: October 10, 2006
• Promulgated Under: 119.03

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see the last paragraph of rule 3745-76-01 of the Administrative Code titled "Incorporation by reference."]

(A)

(1) The landfill owner or operator shall calculate the NMOC emission rate using either the equation provided in paragraph (A)(1)(a) of this rule or the equation provided in paragraph (A)(1)(b) of this rule. Both equations may be used if the actual year-to-year solid waste acceptance rate is known, as specified in paragraph (A)(1)(a) of this rule, for part of the life of the landfill and the actual year-to-year solid waste acceptance rate is unknown, as specified in paragraph (A)(1)(b) of this rule, for part of the life of the landfill. The values to be used in both equations are 0.05 per year for k, one hundred seventy cubic meters per megagram for L_o , and four thousand parts per million by volume as hexane for the C_NMOC . For landfills located in geographical areas with a thirty year annual average precipitation of less than twenty five inches, as measured at the nearest representative official meteorologic site, the k value to be used is 0.02 per year.

(a) The following equation shall be used if the actual year-to-year solid waste acceptance rate is known.

Where, M_NMOC = total NMOC emission rate from the landfill, megagrams per year

k = methane generation rate constant, year^-1

L_o = methane generation potential, cubic meters per megagram solid waste

M_i = mass of solid waste in the i^th section, megagrams

t_i = age of the i^th section, years

C_NMOC = concentration of NMOC, parts per million by volume as hexane

3.6 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 M_i 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,

M_NMOC = mass emission rate of NMOC, megagrams per year

L_o = methane generation potential, cubic meters per megagram solid waste

R = average annual acceptance rate, megagrams per year

k = methane generation rate constant, year^-1

t = age of landfill, years

C_NMOC = concentration of NMOC, parts per million by volume as hexane

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 owner or operator shall compare the calculated NMOC mass emission rate to the standard of fifty megagrams per year.

(a) If the NMOC emission rate calculated in paragraph (A)(1) of this rule is less than fifty megagrams per year, then the landfill owner shall submit an emission rate report as provided in paragraph (B)(1) of rule 3745-76-12 of the Administrative Code, and shall recalculate the NMOC mass emission rate annually as required under paragraph (B)(1) of rule 3745-76-07 of the Administrative Code.

(b) If the calculated NMOC emission rate is equal to or greater than fifty megagrams per year, then the landfill owner shall either comply with paragraph (B)(2) of rule 3745-76-07 of the Administrative Code, or determine a site-specific NMOC concentration and recalculate the NMOC emission rate using the procedures provided in paragraph (A)(3) of this rule.

(3) Tier 2. The landfill owner or operator shall determine the NMOC concentration using the following sampling procedure. The landfill owner or operator shall install at least two sample probes per hectare of landfill surface that has retained waste for at least two years. If the landfill is larger than twenty five hectares in area, only fifty 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 25 or Method 25C of Appendix A of 40 CFR Part 60. Method 18 of Appendix A of 40 CFR Part 60 may be used to analyze the samples collected by the Method 25 or 25C sampling procedure. . If more than the required number of samples are taken, all samples shall be used in the analysis. The landfill owner or operator shall divide the NMOC concentration from Method 25 or Method 25C of Appendix A of 40 CFR part 60 by six to convert from C_NMOC as carbon to C_NMOC as hexane.

(a) Taking composite samples from different probes into a single cylinder is allowed; however, equal sample volumes must be taken from each probe. For each composite, the sampling rate, collection times, beginning and ending cylinder vacuums, or alternative volume measurements must be recorded to verify that composite volumes are equal. Composite sample volumes should not be less than one liter, unless evidence can be provided to substantiate the accuracy of smaller volumes. The compositing shall be terminated before the cylinder approaches ambient pressure where measurement accuracy diminishes.

(b) If using Method 18, the owner or operator must identify all compounds in the sample, and, at a minimum, test for those compounds published in the most recent "Compilation of Air Pollutant Emission Factors (AP-42)", minus carbon monoxide, hydrogen sulfide, and mercury. At a minimum, the instrument must be calibrated for each of the compounds on the list. The concentration of each Method 18 compound shall be converted to C_NMOC as hexane by multiplying it by the ratio of its carbon atoms divided by six.

(c) If the landfill has an active or passive gas removal system in place, Method 25 or Method 25C samples may be collected from these systems instead of surface probes, provided the removal system can be shown to provide sampling as representative as the two sampling probe per hectare requirement. For active collection systems, samples may be collected from the common header pipe before the gas moving or condensate removal equipment. For these systems, a minimum of three samples must be collected from the header pipe.

(d) The landfill owner or operator shall recalculate the NMOC mass emission rate using the equations provided in paragraph (A)(1)(a) or (A)(1)(b) of this rule and using the average NMOC concentration from the collected samples instead of the default value in the equation provided in paragraph (A)(1) of this rule.

(e) If the resulting mass emission rate calculated using the site-specific NMOC concentration is equal to or greater than fifty megagrams per year, then the landfill owner or operator shall either comply with paragraph (B)(2) of rule 3745-76-07 of the Administrative Code, or determine the site-specific methane generation rate constant and recalculate the NMOC emission rate using the site-specific methane generation rate using the procedure specified in paragraph (A)(4) of this rule.

(f) If the resulting NMOC mass emission rate is less than fifty megagrams per year, the owner or operator shall submit a periodic estimate of the emission rate report as provided in paragraph (B)(1) of rule 3745-76-12 of the Administrative Code and retest the site-specific NMOC concentration every five years using the methods specified in this rule.

(4) Tier 3. The site-specific methane generation rate constant shall be determined using the procedures provided in Method 2E of Appendix A of 40 CFR Part 60. The landfill owner or operator shall estimate the NMOC mass emission rate using equations in paragraph (A)(1)(a) or (A)(1)(b) of this rule and using a site-specific methane generation rate constant k, and the site-specific NMOC concentration as determined in paragraph (A)(3) of this rule instead of the default values provided in paragraph (A)(1) of this rule. The landfill owner or operator shall compare the resulting NMOC mass emission rate to the standard of fifty megagrams per year.

(a) If the NMOC mass emission rate as calculated using the site-specific methane generation rate and concentration of NMOC is equal to or greater than fifty megagrams per year, the owner or operator shall comply with paragraph (B)(2) of rule 3745-76-07 of the Administrative Code.

(b) If the NMOC mass emission rate is less than fifty megagrams per year, then the owner or operator shall submit a periodic emission rate report as provided in paragraph (B)(1) of rule 3745-76-12 of the Administrative Code and shall recalculate the NMOC mass emission rate annually, as provided in paragraph (B)(1) of rule 3745-76-12 of the Administrative Code using the equations in paragraph (A)(1) of this rule and using the site-specific methane generation rate constant and NMOC concentration obtained in paragraph (A)(3) of this rule. The calculation of the methane generation rate constant is performed only once, and the value obtained from this test shall be used in all subsequent annual NMOC emission rate calculations.

(5) The owner or operator may use other methods to determine the NMOC concentration or a site-specific k as an alternative to the methods required in paragraphs (A)(3) and (A)(4) of this rule if the method has been approved by the director.

(B) After the installation of a collection and control system in compliance with rule 3745-76-10 of the Administrative Code, the owner or operator shall calculate the NMOC emission rate for purposes of determining when the system can be removed as provided in paragraph (B)(2)(e) of rule 3745-76-07 of the Administrative Code, using the following equation:

M_NMOC = 1.89 10^-3 Q_LFG C_NMOC

Where,

M_NMOC = mass emission rate of NMOC, megagrams per year

Q_LFG = flow rate of landfill gas, cubic meters per minute

C_NMOC = NMOC concentration, parts per million by volume 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 of Appendix A of 40 CFR Part 60.

(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 of Appendix A of 40 CFR Part 60. If using Method 18 of Appendix A of 40 CFR Part 60, the minimum list of compounds to be tested shall be those published in the most recent "Compilation of Air Pollutant Emission Factors (AP-42)". 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 of Appendix A of 40 CFR Part 60 by six to convert from C_NMOC as carbon to C_NMOC as hexane.

(3) The owner or operator may use another method to determine landfill gas flow rate and NMOC concentration if the method has been approved by the director.

(C) When calculating emissions for PSD purposes, the owner or operator of each MSW landfill subject to the provisions of this chapter shall estimate the NMOC emission rate for comparison to the major stationary source and significant levels in rule 3745-31-01 of the Administrative Code using AP-42 or other approved measurement procedures. If a collection system, which complies with the provisions in paragraph (B)(2) of rule 3745-76-07 of the Administrative Code is already installed, the owner or operator shall estimate the NMOC emission rate using the procedures provided in paragraph (B) of this rule.

(D) For the performance test required in paragraph (B)(2)(c)(ii) of rule 3745-76-07 of the Administrative Code, Method 25C or Method 18 of appendix A of 40 CFR Part 60 shall be used to determine compliance with ninety eight weight-per cent efficiency or the twenty parts per million volume outlet concentration level, unless another method to demonstrate compliance has been approved by the director as provided by paragraph (B)(2)(a)(ii) of rule 3745-76-07 of the Administrative Code. If using Method 18 of Appendix A of 40 CFR Part 60, the minimum list of compounds to be tested shall be those published in the most recent "Compilation of Air Pollutant Emission Factors (AP-42)". The following equation shall be used to calculate efficiency:

Control efficiency = (NMOC_IN - NMOC_OUT) / (NMOC_IN)

Where,

NMOC_IN = mass of NMOC entering control device

NMOC_OUT = mass of NMOC exiting control device

Rule 3745-76-10 | Compliance provisions.

• Effective: August 25, 2016
• Promulgated Under: 119.03

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see paragraph (B)(31) of rule 3745-76-01 of the Administrative Code titled "Referenced materials."]

(A) Except as provided in paragraph (B)(2)(a)(ii) of rule 3745-76-07 of the Administrative Code, the specified methods in paragraphs (A)(1) to (A)(6) of this rule shall be used to determine whether the gas collection system is in compliance with paragraph (B)(2)(b) of rule 3745-76-07 of the Administrative Code.

(1) For the purposes of calculating the maximum expected gas generation flow rate from the landfill to determine compliance with paragraph (B)(2)(b)(i)(a) of rule 3745-76-07 of the Administrative Code, one of the following equations shall be used. The k and l_o kinetic factors should be those published in the most recent "Compilation of Air Pollutant Emission Factors (AP-42)" or other site specific values demonstrated to be appropriate and approved by the director. If k has been determined as specified in paragraph (A)(4) of rule 3745-76-09 of the Administrative Code, the value of k determined from the test shall be used. A value of no more than fifteen years shall be used for the intended use period of the gas mover equipment. 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:

Q_M = 2L_oR (e^-kc -e^-kt)

Where,

Q_M = maximum expected gas generation flow rate, cubic meters per year

L_o = methane generation potential, cubic meters per megagram solid waste

R = average annual acceptance rate, megagrams per year

k = methane generation rate constant, year^-1

t = age of the landfill at equipment installation plus the 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 is the age of the landfill at installation, years

c = time since closure, years (for an active landfill c = O and e^-kc = 1)

(b) For sites with known year-to-year solid waste acceptance rate:

Where,

Q_M = maximum expected gas generation flow rate, cubic meters per year

k = methane generation rate constant, year^-1

L_o = methane generation potential, cubic meters per megagram solid waste

M_i = mass of solid waste in the i^th section, megagrams

t_i = age of the i^th section, years

(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 paragraph (A)(1)(a) and paragraph (A)(1)(b) of this rule. If the landfill is still accepting waste, the actual measured flow data will not equal the maximum expected gas generation rate, so calculations using the equations in paragraph (A)(1)(a) or (A)(1)(b) of this rule or other methods shall be used to predict the maximum expected gas generation rate over the intended period of use of the gas control system equipment.

(2) For the purposes of determining sufficient density of gas collectors for compliance with paragraph (B)(2)(b)(i)(b) of rule 3745-76-07 of the Administrative Code, the owner or operator shall design a system of vertical wells, horizontal collectors, or other collection devices, satisfactory to the director, capable of controlling and extracting gas from all portions of the landfill sufficient to meet all operational and performance standards.

(3) For the purpose of demonstrating whether the gas collection system flow rate is sufficient to determine compliance with paragraph (B)(2)(b)(i)(c) of rule 3745-76-07 of the Administrative Code, the owner or operator shall measure gauge pressure in the gas collection header at each individual well, monthly. If a positive pressure exists, action shall be initiated to correct the exceedance within five calendar days, except for the three conditions allowed under paragraph (B) of rule 3745-76-08 of the Administrative Code. If negative pressure cannot be achieved without excess air infiltration within fifteen calendar days of the first measurement, the gas collection system shall be expanded to correct the exceedance within one hundred twenty days of the initial measurement of positive pressure. Any attempted corrective measure shall not cause exceedances of other operational or performance standards. An alternative timeline for correcting the exceedance may be submitted to the Director for approval.

(4) Owners or operators are not required to expand the system as required in paragraph (A)(3) of this rule during the first one hundred eighty days after gas collection system start-up.

(5) For the purpose of identifying whether excess air infiltration into the landfill is occurring, the owner or operator shall monitor each well monthly for temperature and nitrogen or oxygen as provided in paragraph (C) of rule 3745-76-08 of the Administrative Code. If a well exceeds one of these operating parameters, action shall be initiated to correct the exceedance within five calendar days. If correction of the exceedance cannot be achieved within fifteen calendar days of the first measurement, the gas collection system shall be expanded to correct the exceedance within one hundred twenty days of the initial exceedance. Any attempted corrective measure shall not cause exceedances of other operational or performance standards. An alternative timeline for correcting the exceedance may be submitted to the Director for approval.

(6) An owner or operator seeking to demonstrate compliance with paragraph (B)(2)(b)(i)(d) of rule 3745-76-07 of the Administrative Code through the use of a collection system not conforming to the specifications provided in rule 3745-76-14 of the Administrative Code shall provide information satisfactory to the director as specified in paragraph (B)(2)(a)(iii) of rule 3745-76-07 of the Administrative Code demonstrating that off-site migration is being controlled.

(B) For purposes of compliance with paragraph (A) of rule 3745-76-08 of the Administrative Code, each owner or operator of a controlled landfill shall place each well or design component as specified in the approved design plan as provided in paragraph (B)(2)(a) of rule 3745-76-07 of the Administrative Code. Each well shall be installed no later than sixty days after the date on which the initial solid waste has been in place for a period of:

(1) Five years or more if active; or

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

Each well shall be installed as a measure to abate or minimize the migration of explosive gas when the director orders the owner or operator to perform such measures pursuant to paragraph (D) of rule 3745-76-08 of the Administrative Code.

(C) The following procedures shall be used for compliance with the surface methane operational standard as provided in paragraph (D) of rule 3745-76-08 of the Administrative Code.

(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 thirty meter intervals (or a 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 paragraph (D) of this rule.

(2) The background concentration shall be determined by moving the probe inlet upwind and downwind outside the boundary of the landfill at a distance of at least thirty meters from the perimeter wells.

(3) Surface emission monitoring shall be performed in accordance with section 8.3.1 of Method 21 of Appendix A of 40 CFR Part 60, except that the probe inlet shall be placed within five to ten centimeters of the ground. Monitoring shall be performed during typical meteorological conditions.

(4) Any reading of five hundred parts per million or more above background at any location shall be recorded as a monitored exceedance and the actions specified in paragraphs (C)(4)(a) to (C)(4)(e) of this rule shall be taken. As long as the specified actions are taken, the exceedance is not a violation of the operational requirements of paragraph (D) of rule 3745-76-08 of the Administrative Code.

(a) The location of each monitored exceedance shall be marked and the location recorded.

(b) Cover maintenance or adjustments to the vacuum of the adjacent wells to increase the gas collection in the vicinity of each exceedance shall be made and the location shall be re-monitored within ten calendar days of detecting the exceedance.

(c) If the re-monitoring of the location shows a second exceedance, additional corrective action shall be taken and the location shall be monitored again within ten days of the second exceedance. If the re-monitoring shows a third exceedance for the same location, the action specified in paragraph (C)(4)(e) of this rule shall be taken, and no further monitoring of that location is required until the action specified in paragraph (C)(4)(e) of this rule has been taken.

(d) Any location that initially showed an exceedance but has a methane concentration less than five hundred parts per million methane above background at the ten-day re-monitoring specified in paragraph (C)(4)(b) or (C)(4)(c) of this rule shall be re-monitored one month from the initial exceedance. If the one-month re-monitoring shows a concentration less than five hundred parts per million above background, no further monitoring of that location is required until the next quarterly monitoring period. If the one-month re-monitoring shows an exceedance, the actions specified in paragraph (C)(4)(c) or (C)(4)(e) of this rule shall be taken.

(e) For any location where monitored methane concentration equals or exceeds five hundred parts per million above background three times within a quarterly period, a new well or other collection device shall be installed within one hundred twenty calendar days of the initial exceedance. An alternative remedy to the exceedance, such as upgrading the blower, header pipes or control device, and a corresponding timeline for installation may be submitted to the director 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, and as specified in paragraph (E)(12) of rule 3745-27-19 of the Administrative Code and paragraph (A) of rule 3745-27-14 of the Administrative Code.

(D) Each owner or operator seeking to comply with the provisions in paragraph (C) of this rule shall comply with the following instrumentation specifications and procedures for surface emission monitoring devices:

(1) The portable analyzer shall meet the instrument specifications provided in section 6 of Method 21 of Appendix A of 40 CFR Part 60, except that "methane" shall replace all references to VOC.

(2) The calibration gas shall be methane, diluted to a nominal concentration of five hundred parts per million in air.

(3) To meet the performance evaluation requirements in section 6 of Method 21 of Appendix A of 40 CFR Part 60, the instrument evaluation procedures of section 8.1 of Method 21 of Appendix A of 40 CFR Part 60 shall be used.

(4) The calibration procedures provided in section 8.1.1.1 of Method 21 of Appendix A of 40 CFR Part 60 shall be followed immediately before commencing a surface monitoring survey.

(E) The provisions of this rule apply at all times, except during periods of start-up, shutdown, or malfunction, provided that the duration of start-up, shutdown, or malfunction shall not exceed five days for collection systems and shall not exceed one hour for treatment or control devices.

Rule 3745-76-14 | Specifications for active collection systems.

• Effective: October 10, 2006
• Promulgated Under: 119.03

(A) Each owner or operator seeking to comply with paragraph (B)(2)(a) of rule 3745-76-07 of the Administrative Code shall site active collection wells, horizontal collectors, surface collectors, or other extraction devices at a sufficient density throughout all gas producing areas using the following procedures unless alternative procedures have been approved by the director as provided in paragraph (B)(2)(a)(iii) of rule 3745-76-07 of the Administrative Code and paragraph (B)(2)(a)(iv)) of rule 3745-76-07 of the Administrative Code:

(1) The collection devices within the interior and along the perimeter areas shall be certified to achieve comprehensive control of surface gas emissions by a professional engineer. The following issues shall be addressed in the design: depths of refuse, refuse gas generation rates and flow characteristics, cover properties, gas system expandibility, leachate and condensate management, accessibility, compatibility with filling operations, integration with closure end use, air intrusion control, corrosion resistance, fill settlement, resistance to the refuse decomposition heat, and maintenance of the integrity of the final cover around each well.

(2) The sufficient density of gas collection devices determined in paragraph (A)(1) of this rule 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.

(3) The placement of gas collection devices determined in paragraph (A)(1) of this rule shall control all gas producing areas, except as provided by paragraphs (A)(3)(a) and (A)(3)(b) of this rule.

(a) Any segregated area of asbestos or nondegradable material may be excluded from collection if documented as provided under paragraph (D) of rule 3745-76-13 of the Administrative Code. 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 director upon request.

(b) 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 one 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 director 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. Emissions from each section shall be computed using the following equation:

Where,

Q_i = NMOC emission rate from the i^th section, megagrams per year

k = methane generation rate constant, year^-1

L_o = methane generation potential, cubic meters per megagram solid waste

M_i = mass of the degradable solid waste in the i^th section, megagram

t_i = age of the solid waste in the i^th section, years

C_NMOC = concentration of nonmethane organic compounds, parts per million by volume

3.6 10^-9 = conversion factor

(c) 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 paragraph (A)(1) of rule 3745-76-09 of the Administrative Code or the alternative values from paragraph (A)(5) of rule 3745-76-09 of the Administrative Code 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 as provided in paragraph (A)(3)(a) of this rule.

(B) Each owner or operator seeking to comply with paragraph (B)(2)(a)(i) of rule 3745-76-07 of the Administrative Code shall construct the gas collection devices using the following equipment or procedures:

(1) 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.

(2) 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 or 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.

(3) 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.

(C) Each owner or operator seeking to comply with paragraph (B)(2)(a)(i) of rule 3745-76-07 of the Administrative Code shall convey the landfill gas to a control system in compliance with paragraph (B)(2)(c) of rule 3745-76-07 of the Administrative Code through the collection header pipe(s). The gas mover equipment shall be sized to handle the maximum gas generation flow rate expected over the intended use period of the gas moving equipment using the following procedures:

(1) For existing collection systems, the flow data shall be used to project the maximum flow rate. If no flow data exists, the procedures in paragraph (C)(2) of this rule shall be used.

(2) For new collection systems, the maximum flow rate shall be in accordance with paragraph (A)(1) of rule 3745-76-10 of the Administrative Code.

(b) Steam-assisted and nonassisted flares shall be designed for and operated with an exit velocity less than 18.3 meters per second (sixty feet per second), as determined by the methods specified in paragraph (D)(4) of this rule, except as provided in paragraphs (B)(1)(c) and (B)(1)(d) of this rule.

(c) If the net heating value of the gas being combusted is greater than 37.3 megajoules per standard cubic foot (one thousand Btu per standard cubic foot), steam-assisted and nonassisted flares can be designed for and operated with an exit velocity equal to or greater than 18.3 meters per second (sixty feet per second) but less than one hundred and twenty-two meters per second (four hundred feet per second), as determined by the methods specified in paragraph (D)(4) of this rule.

(d) Steam-assisted and nonassisted flares may be designed for and operated with an exit velocity less than that calculated for the velocity (V_max ) below and less than one hundred and twenty two meters per second (four hundred feet per second). This maximum permitted velocity shall be calculated as follows:

Log₁₀ (V_max) = (H_T + 28.8)/31.7

where:

V_max = maximum permitted velocity, meters per second;

28.8 = constant;

31.7 = constant; and

H_T = the net heating value as determined in paragraph (D)(3) of this rule.

The actual exit velocity of the flare shall be determined by the methods specified in paragraph (D)(4) of this rule.

(e) Air-assisted flares shall be designed and operated with an exit velocity less than the velocity, V_max , calculated as follows:

V_max = 8.706 + 0.7084 (H_T)

where:

V_max = maximum permitted velocity, meters per second;

8.706 = constant;

0.7084 = constant; and

H_T = the net heating value as determined in paragraph (D)(3) of this rule.

The actual exit velocity of the flare shall be determined by the methods specified in paragraph (D)(4) of this rule.

(2) Nonassisted flares with a hydrogen content of at least eight per cent (by volume)

(a) Nonassisted flares shall be used that have a diameter of three inches or greater, and a hydrogen content of 8.0 per cent (by volume), or greater, and shall be designed for and operated with an exit velocity of less than 37.2 meters per second (one hundred and twenty two feet per second) and less than the velocity, V_max, as determined by the following equation:

V_max = (X_H2-K₁) K₂

Where:

V_max = maximum permitted velocity, meters per second;

K₁ = constant, 6.0 volume-per cent hydrogen;

K₂ = constant, 3.9 meters per second per volume-per cent hydrogen; and

X_H2 = the volume-per cent of hydrogen, on a wet basis, as calculated by using the ASTM D1946-90.

The actual exit velocity of the flare shall be determined by the methods specified in paragraph (D)(4) of this rule.

(C) Owners or operators of flares used to comply with the provisions of this chapter shall monitor these control devices to ensure that they are operated and maintained in conformance with their design. Monitoring and record keeping shall be maintained as required in paragraph (C)(4) of rule 3745-76-13 and paragraph (C) of rule 3745-76-11 of the Administrative Code.

(D) Compliance determination

(1) Reference Method 22 shall be used to determine the compliance of flares with the visible emission provisions of this rule. An observation period of two hours shall be used in accordance with the requirements of Method 22.

(2) The presence of a flare pilot flame shall be monitored using a thermocouple or other equivalent device to detect the presence of a flame.

(3) The net heating value of the gas being combusted in a flare shall be calculated using the following equation:

Where:

k = constant, 1.740 10^{- 7} (megajoule-gram mole per parts per million-standard cubic meter-kilocalorie), where the standard temperature for ( gram mole per standard cubic meter ) is twenty degrees Celsius;

H_T = net heating value of the sample, megajoules per standard cubic meter; where the net enthalpy per mole of offgas is based on combustion at twenty five degrees Celsius and seven hundred sixty millimeters of mercury, but the standard temperature for determining the volume corresponding to one mole is twenty degrees Celsius;

C_i = concentration of sample component i in ppm on a wet basis, as measured for organics by Method 18 of Appendix A of 40 CFR Part 60and measured for hydrogen and carbon monoxide by ASTM D1946- 90;

H_i = net heat of combustion of sample component i, kilocalorie per gram mole at twenty five degrees Celsius and seven hundred sixty millimeters of mercury. The heats of combustion may be determined using ASTM D4809-95 if published values are not available or cannot be calculated.

(4) The actual exit velocity of a flare shall be determined by dividing the volumetric flowrate (in units of standard temperature and pressure), as determined by Reference Methods 2, 2A, 2C, or 2D as appropriate; by the unobstructed (free) cross sectional area of the flare tip.
