9VAC5-40-5810. Definitions.

A. For the purpose of applying this article in the context of the Regulations for the Control and Abatement of Air Pollution and related uses, the words or terms shall have the meanings given them in subsection C of this section.

B. As used in this article, all terms not defined here shall have the meanings given them in 9VAC5 Chapter 10 (9VAC5-10), unless otherwise required by context.

C. Terms defined.

"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 planned to accept waste in the future.

"CERCLA" means the federal Comprehensive Environmental Response, Compensation and Liability Act (42 USC § 9601 et seq.).

"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, as prescribed under 40 CFR 60.7(a)(4), with the board. Once a notification of modification has been filed, and additional solid waste is placed in the landfill, the landfill is no longer closed.

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

"Commenced" means that an owner has undertaken a continuous program of construction or modification or that an owner has entered into a contractual obligation to undertake and complete, within a reasonable time, a continuous program of construction or modification.

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

"Construction" means fabrication, erection, or installation of an affected facility.

"Controlled landfill" means any landfill at which collection and control systems are required under this article 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 9VAC5-40-5820 C 2 a.

"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 department under ~~Part VII (9VAC20-80-480 et seq.) of 9VAC20 Chapter 80 (Solid Waste Management Regulations)~~ Part V (9VAC20-81-400 et seq.) of the Solid Waste Management Regulations, plus any in-place waste not accounted for in the most recent permit, or as calculated using good engineering practices acceptable to the board. If the owner chooses to convert the design capacity from volume to mass or from mass to volume to demonstrate that its design capacity is less than (i) 1.0 million megagrams or 1.0 million cubic meters in the Northern Virginia Volatile Organic Compound Emissions Control Area or (ii) 2.5 million megagrams or 2.5 million cubic meters in the remaining areas of the Commonwealth, the calculation must include a site-specific density, which must be recalculated annually.

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

"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.

"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.

"Federal operating permit" means a permit issued under Article 1 (9VAC5-80-50 et seq.) of Part II of 9VAC5 Chapter 80.

"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.

Such waste may include, but is not limited to, waste resulting from the following manufacturing processes: electric power generation; fertilizer and agricultural chemicals; food and related products and byproducts; inorganic chemicals; iron and steel manufacturing; leather and leather products; nonferrous metals manufacturing and 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 waste. 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, injection well, or waste pile as those terms are defined under ~~9VAC20-80-10~~9VAC20-81.

"Landfill gas" means any gas derived from the decomposition of organic waste deposited in an MSW landfill or from the evolution of volatile organic species in the waste. Emissions from MSW landfills is equivalent to landfill gas emissions.

"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.

"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 commences construction on the horizontal or vertical expansion.

"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 solid wastes regulated under Subtitle D (42 USC § 6941 et seq.) of RCRA (as reflected in 40 CFR 257.2) and implemented by the department in ~~9VAC20-80-250~~9VAC20-81 (Solid Waste Management Regulations) such as commercial solid waste, nonhazardous sludge, conditionally exempt small quantity generator waste, and nonhazardous industrial solid waste.

b. Recalculate the NMOC emission rate annually using the procedures specified in 9VAC5-40-5860 B 1 until such time as the calculated NMOC emission rate is greater than or equal to (i) 23 megagrams per year in the Northern Virginia Volatile Organic Compound Emissions Control Area or (ii) 50 megagrams per year in the remaining areas of the Commonwealth, or the landfill is closed.

(1) If the NMOC emission rate, upon initial calculation or annual recalculation required in subdivision C 1 b of this section, is greater than or equal to (i) 23 megagrams per year in the Northern Virginia Volatile Organic Compound Emissions Control Area or (ii) 50 megagrams per year in the remaining areas of the Commonwealth, the owner shall install a collection and control system in compliance with subdivision C 2 of this section.

(2) If the landfill is permanently closed, a closure notification shall be submitted to the board as provided for in 9VAC5-40-5880 F.

2. If the calculated NMOC emission rate is greater than or equal to (i) 23 megagrams per year in the Northern Virginia Volatile Organic Compound Emissions Control Area or (ii) 50 megagrams per year in the remaining areas of the Commonwealth, the owner shall:

a. Submit a collection and control system design plan prepared by a professional engineer to the board within one year:

(1) The collection and control system as described in the plan shall meet the design requirements of subdivision C 2 b of this section.

(2) The collection and control system design plan shall include any alternatives to the operational standards, test methods, procedures, compliance measures, monitoring, recordkeeping or reporting provisions of 9VAC5-40-5822, 9VAC5-40-5850, 9VAC5-40-5860, 9VAC5-40-5870, 9VAC5-40-5880, and 9VAC5-40-5890 proposed by the owner.

(4) The board will review the information submitted under subdivisions C 2 a (1), (2) and (3) of this section and either approve it, disapprove it, or request that additional information be submitted. Because of the many site-specific factors involved with landfill gas system design, alternative systems may be necessary. A wide variety of system designs are possible, such as vertical wells, combination horizontal and vertical collection systems, or horizontal trenches only, leachate collection components, and passive systems. All design plan changes shall be submitted to the board and may be implemented only upon approval of the board.

b. Install a collection and control system that captures the gas generated within the landfill as required by subdivision C 2 b (1) or (2) of this section within 30 months after the first annual report in which the emission rate equals or exceeds (i) 23 megagrams per year in the Northern Virginia Volatile Organic Compound Emissions Control Area or (ii) 50 megagrams per year in the remaining areas of the Commonwealth, unless Tier 2 or Tier 3 sampling demonstrates that the emission rate is less than (a) 23 megagrams per year in the Northern Virginia Volatile Organic Compound Emissions Control Area or (b) 50 megagrams per year in the remaining areas of the Commonwealth, as specified in 9VAC5-40-5880 E 1 or E 2.

(1) An active collection system shall:

2. The owner meets the conditions for control system removal specified in 9VAC5-40-5820 C 2 e.

9VAC5-40-5850. Compliance.

A. The provisions of 9VAC5-40-20 (Compliance) apply.

B. Owners subject to 9VAC5-40-5820 shall comply with the provisions of ~~Part V (9VAC20-80-240 et seq.)~~Part III (9VAC20-81-100 et seq.) of 9VAC20 Chapter 8081 (Solid Waste Management Regulations) pertaining to the control of landfill gases.

C. Except as provided in 9VAC5-40-5820 C 2 a (2), the specified methods in subdivisions C 1 through C 6 of this section shall be used to determine whether the gas collection system is in compliance with 9VAC5-40-5820 C 2 b.

1. For the purposes of calculating the maximum expected gas generation flow rate from the landfill to determine compliance with 9VAC5-40-5820 C 2 b (1) (a), one of the following equations shall be used. The k and L sub0 kinetic factors should be those published in the "Compilation of Air Pollutant Emission Factors (AP-42)" (see 9VAC5-20-21) or other site-specific values demonstrated to be appropriate and approved by the board. If k has been determined as specified in 9VAC5-40-5860 B 4, 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 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 = 2L₀R(e^-kc - e^-kt)

where

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

L₀ = 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 = 0 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

L₀ = 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 subdivisions C 1 a and 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 using the equations in subdivisions C 1 a or b of this section or other methods acceptable to the board 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 9VAC5-40-5820 C 2 b (1) (b), the owner shall design a system of vertical wells, horizontal collectors, or other collection devices, acceptable to the board, 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 9VAC5-40-5820 C 2 b (1) (c), the owner 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 9VAC5-40-5822 A 2. If negative pressure cannot be achieved without excess air infiltration within 15 calendar days of the first measurement, the gas collection system shall be expanded to correct the exceedance within 120 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 board for approval.

4. Owners are not required to expand the system as required in subdivision C 3 of this section during the first 180 days after gas collection system startup.

5. For the purpose of identifying whether excess air infiltration into the landfill is occurring, the owner shall monitor each well monthly for temperature and nitrogen or oxygen as provided in 9VAC5-40-5822 A 3. 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 15 calendar days of the first measurement, the gas collection system shall be expanded to correct the exceedance within 120 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 board for approval.

6. An owner seeking to demonstrate compliance with 9VAC5-40-5820 C 2 b (1) (d) through the use of a collection system not conforming to the specifications provided in 9VAC5-40-5824 shall provide information acceptable to the board as specified in 9VAC5-40-5820 C 2 a (3) demonstrating that off-site migration is being controlled.

D. For purposes of compliance with 9VAC5-40-5822 A 1, each owner of a controlled landfill shall place each well or design component as specified in the approved design plan as provided in 9VAC5-40-5820 C 2 a. 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. Five years or more if active; or

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

E. The following procedures shall be used for compliance with the surface methane operational standard as provided in 9VAC5-40-5822 A 4.

1. After installation of the collection system, the owner 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 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 subsection F of this section.

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 30 meters from the perimeter wells.

3. Surface emission monitoring shall be performed in accordance with § 4.3.1 of Reference Method 21 of Appendix A of 40 CFR Part 60, except that the probe inlet shall be placed within 5 to 10 centimeters of the ground. Monitoring shall be performed during typical meteorological conditions.

4. Any reading of 500 parts per million or more above background at any location shall be recorded as a monitored exceedance and the actions specified in subdivisions E 4 a through e of this section shall be taken. As long as the specified actions are taken, the exceedance is not a violation of the operational requirements of 9VAC5-40-5822 A 4.

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 remonitored within 10 calendar days of detecting the exceedance.

c. If the remonitoring of the location shows a second exceedance, additional corrective action shall be taken and the location shall be monitored again within 10 days of the second exceedance. If the remonitoring shows a third exceedance for the same location, the action specified in subdivision E 4 e of this section shall be taken, and no further monitoring of that location is required until the action specified in subdivision E 4 e of this section has been taken.

d. Any location that initially showed an exceedance but has a methane concentration less than 500 parts per million methane above background at the 10-day remonitoring specified in subdivision E 4 b or c of this section shall be remonitored one month from the initial exceedance. If the one-month remonitoring shows a concentration less than 500 parts per million above background, no further monitoring of that location is required until the next quarterly monitoring period. If the 1-month remonitoring shows an exceedance, the actions specified in subdivision E 4 c or e of this section shall be taken.

e. For any location where monitored methane concentration equals or exceeds 500 parts per million above background three times within a quarterly period, a new well or other collection device shall be installed within 120 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 board for approval.

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

F. Each owner seeking to comply with the provisions in subsection E of this section 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 § 3 of Reference 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 500 parts per million in air.

3. To meet the performance evaluation requirements in § 3.1.3 of Reference Method 21 of Appendix A of 40 CFR Part 60, the instrument evaluation procedures of § 4.4 of Reference Method 21 of Appendix A of 40 CFR Part 60 shall be used.

4. The calibration procedures provided in § 4.2 of Reference Method 21 of Appendix A of 40 CFR Part 60 shall be followed immediately before commencing a surface monitoring survey.

G. The provisions of this article apply at all times, except during periods of startup, shutdown, or malfunction, provided that the duration of startup, shutdown, or malfunction shall not exceed five days for collection systems and shall not exceed one hour for treatment or control devices. This subsection shall not apply to the emission standards set forth in 9VAC5-40-5830 and 9VAC5-40-5840.

2. In order to assist local governments in the development of ordinances acceptable to the board, the ordinance in subsection C of this section is offered as a model.

3. If a local government wishes to adopt the language of the model ordinance without changing any wording except that enclosed by parentheses, that government's ordinance shall be deemed to be approved by the board on the date of local adoption provided that a copy of the ordinance is filed with the department upon its adoption by the local government.

4. If a local government wishes to change any wording of the model ordinance aside from that enclosed by parentheses in order to construct a local ordinance, that government shall request the approval of the board prior to adoption of the ordinance by the local jurisdiction. A copy of the ordinance shall be filed with the department upon its adoption by the local government.

5. Local ordinances that have been approved by the board prior to April 1, 1996, remain in full force and effect as specified by their promulgating authorities.

B. Establishment and approval of local ordinances varying from the model.

1. Any local governing body proposing to adopt or amend an ordinance relating to open burning that differs from the model local ordinance in subsection C of this section shall first obtain the approval of the board for the ordinance or amendment as specified in subdivision A 4 of this section.
