Ohio Admin. Code 3745-76-10 - Compliance provisions
[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 Incorporation by
reference
(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 kinetic factors should be those published in the most recent
"Compilationoof 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:

Where,
QM = maximum expected gas generation flow rate, cubic meters per year
Lo = 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,
QM = maximum expected gas generation flow rate, cubic meters per year
k = methane generation rate constant, year-1
Lo = methane generation potential, cubic meters per megagram solid waste
Mi = mass of solid waste in the ith section, megagrams
t i = age of the ith 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 (O)
of rule
3745-76-12
(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.
