for carbon sequestration that occurred during the time periods for which the
project intends to be awarded CO2 offset allowances
pursuant to subsection 9(F) of this Chapter, and such credits were cancelled or
retired for the sole purpose of allowing the project to be awarded
CO2 offset allowances pursuant to subsection 9(F) of
this Chapter.
For such projects, the number of CO2
offset allowances to be awarded will be calculated pursuant to the requirements
of subsection 9(D)(2) of this Chapter without regard to quantity of credits
that were awarded to the project under the voluntary program.
(3) Avoided
methane (CH4) emissions from agricultural manure

absence of the offset project through the uncontrolled anaerobic storage of
manure, or organic food wastes.
(ii) Eligible offset projects shall employ
only manure-based anaerobic digester systems using livestock manure as the
majority of digester feedstock, defined as more than 50% of the mass input into
the digester on an annual basis. Organic food wastes used by an anaerobic
digester shall only be that which would have been stored in anaerobic
conditions in the absence of the offset project.
(iii) The provisions of subsections
9(B)(3)(b) and (c) of this Chapter shall not apply to agricultural manure
methane offset projects provided either of the following requirements are met:

digester projects in the applicable state at the time of submission of a
consistency application pursuant to subsection 9(C) of this Chapter.
MGSTATE = average annual manure
production of all dairy cows and swine in the state at the time of submission
of a consistency application pursuant to subsection 9(C) of this
Chapter.
(B) The offset
project is located at a farm with 4,000 or less head of dairy cows, or a farm
with equivalent animal units, assuming an average live weight for dairy cows
(lbs./cow) of 1,400 lbs., or, if the project is a regional-type anaerobic
digester, total annual manure input to the digester is designed to be less than
the average annual manure produced by a farm with 4,000 or less head of dairy
cows, or a farm with equivalent animal units, assuming an average live weight
for dairy cows (lbs./cow) of 1,400 lbs.
(b) Offset project description. The offset
project sponsor shall provide a detailed narrative of the offset project
actions to be taken, including documentation that the offset project meets the
eligibility requirements of subsection 9(D)(3)(a) of this Chapter. The offset

installed and a technical schematic of the offset project; and
(v) Location and specifications of the
facilities from which anaerobic digester influent will be received, if
different from the facility where the offset project will occur.
(c) Emissions baseline
determination. The emissions baseline shall represent the potential emissions
of the methane (CH4) that would have been produced in a
baseline scenario under uncontrolled anaerobic storage conditions and released
directly to the atmosphere in the absence of the offset project.
(i) Baseline CH4
emissions shall be calculated as follows:
Eb(tons) = (Vm
x M)/2000 x GWP where:
Eb= Potential
CO2e emissions due to calculated
CH4 production under site-specific anaerobic storage and
weather conditions(tons);
Vm = Volume of
CH4 produced each month from decomposition of volatile
solids in a baseline uncontrolled anaerobic storage scenario under
site-specific storage and GWP(ft3); and M = Mass of
CH4 per cubic foot (0.04246 lb/ft³ default value at
one atmosphere and 20°C) GWP = Global warming potential of
CH4 (28)
(ii) The estimated amount of volatile solids
(kg) decomposed each month under the uncontrolled anaerobic storage baseline
scenario shall be calculated as follows:
VSdec= VSavail
* f
where:
VSdec = volatile solids decomposed
monthly (kg)
VSavail = volatile solids available
for decomposition in manure storage each month as determined from the
equation:
VSavail = (Mp +
1/2 Min - Mout) x
TS% x VS%
where:
Mp = manure or organic food waste
storage present at the beginning of a month (left over from the previous month)
(kg);
Min = manure or organic food waste
added to storage during the course of the month (kg). This number is multiplied
by a factor of 1/2 to represent the average mass of manure or organic food
waste available for decomposition for the duration of the entire month; and
Mout = manure or organic food waste
removed from storage for land application or export (assumed value based on
standard farm practice)
TS% = concentration (percent) of total
solids in manure as determined through EPA 160.3 testing method (U.S. EPA
Method Number 160.3, Methods for the Chemical Analysis of Water and Wastes
(MCAWW) (EPA/600/4-79/020)); and VS% = concentration
(percent) of volatile solids in total solids as determined through EPA 160.4
testing method (U.S. EPA Method Number 160.4, Methods for the Chemical Analysis
of Water and Wastes (MCAWW) (EPA/600/4-79/020))
and
f = van't Hoff-Arrhenius factor for the specific month as
determined using the equation below if the reported temperature used to
determine T2 below is above 5°C; if the reported
temperature is below 5°C, then f = 0.104. Using a base temperature of
30°C, the equation is as follows:
f = exp[E * (T2 -
T1)/(GC * T1 *
T2)]
where:
f = conversion efficiency of VS to CH4
per month
E = activation energy constant (15,175 cal/mol)
T2 = average monthly ambient
temperature for the facility where manure or organic waste is generated
(converted from ° Celsius to° Kelvin) as determined from the nearest
National Weather Service certified weather station;
T1 = 303.15 (30° C converted to ° K)
GC = ideal gas constant (1.987 cal/K mol)
(iii) The volume of
CH4 produced (ft3) from
degradation of volatile solids shall be calculated as follows:
Vm = (VSdecx
Bo) x 35.3147
where:
Vm = volume of
CH4 (ft3);
VSdeg = volatile solids decomposed
(kg); and Bo = manure type-specific maximum methane
(CH4) generation constant
(m3) CH4/kg VS decomposed).
For dairy cow manure, Bo = 0.24
m3 CH4/kg VS decomposed. The
methane generation constant for other types of manure shall be those cited in
U.S. EPA, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2010,
Annex 3 Table A180 (U.S. EPA, February, 2017), unless the project sponsor
proposes an alternate methane generation constant and that alternate is
approved by the Department. If the project sponsor proposes to use a methane
generation constant other than the one found in the above-cited reference, the
project sponsor must provide justification and documentation to the Department.
(d) Calculating
emissions reductions. Emissions reductions shall be calculated as follows:
ERt = Eb - Ep
where:
ERt = CO2e emissions reductions due to
project activities (tons);
Eb = Potential CO2e emissions due to
calculated CH4 production under site-specific anaerobic storage and weather
conditions (tons); and Ep = CO2e emissions due to
project activities additional to baseline (tons), including, but not limited
to, manure transportation, flaring, venting, and effluent management.
Emissions reductions may not exceed the potential emissions
of the anaerobic digester, as represented by the annual volume of
CH4 produced by the anaerobic digester, as monitored
pursuant to subsection 9(D)(3)(e) of this Chapter. CO2
emissions due to transportation of manure and organic food wastes from the
sites where the manure and organic food wastes were generated to the anaerobic
digester shall be subtracted from the emissions reduction calculated pursuant
to subsections 9(D)(3)(c)(i) through (iii) of this Chapter. Transport
CO2 emissions shall be determined through one of the
following methods:
(i) Documentation
of transport fuel use for all shipments of manure and organic food wastes from
off-site to the anaerobic digester during each reporting year and a log of
transport miles for each shipment. Off-site is defined as a location that is
not contiguous with the property where the anaerobic digester is located.
CO2 emissions shall be determined through the
application of an emissions factor for the fuel type used. If this option is
chosen, the following emission factors shall be applied as appropriate:
(A) Diesel fuel: 22.912 lbs.
CO2/gallon.
(B) Gasoline: 19.878 lbs.
CO2/gallon.
(C) Other fuel: submitted emission factor
approved by the Department.
(ii) Documentation of total tons of manure
transported from off-site for input into the anaerobic digester during each
reporting year, as monitored pursuant to subsection 9(D)(3)(e)(i) of this
Chapter, and a log of transport miles and fuel type used for each shipment.
CO2 emissions shall be determined through the
application of a ton-mile transport emission factor for the fuel type used. If
this option is chosen, the following emission factors shall be applied as
appropriate for each ton of manure delivered, and multiplied by the number of
miles transported:
(A) Diesel fuel: 0.131 lbs.
CO2 per ton-mile.
(B) Gasoline: 0.133 lbs.
CO2 per ton-mile.
(C) Other fuel: submitted emission factor
approved by the Department.
(e) Monitoring and verification requirements.
Offset projects shall employ a system that provides metering of biogas
volumetric flow rate and determination of CH4
concentration. Monitoring and verification reports shall include monthly biogas
volumetric flow rate and CH4 concentration
determination. Monitoring and verification shall also meet the following
requirements:
(i) If the offset project is a
regional-type an aerobicdigester, manure and organic food waste from each
distinct source supplying to the anaerobic digester shall be sampled monthly to
determine the amount of volatile solids present. Any emissions reduction will
be calculated according to mass of manure and organic food waste (kg) being
digested and percentage of volatile solids present before digestion, consistent
with the requirements of subsections 9(D)(3)(c) and 9(D)(3)(e) (iii) of this
Chapter, and apportioned accordingly among sources. The project sponsor shall
provide supporting material and receipts tracking the monthly receipt of manure
and organic food waste (kg) used to supply the anaerobic digester from each
supplier.
(ii) If the offset
project includes the digestion of organic food wastes eligible pursuant to
subsection 9(D)(3)(a) (ii) of this Chapter, organic food wastes shall be
sampled monthly to determine the amount of volatile solids present before
digestion, consistent with the requirements of subsections 9(D)(3)(c) and
9(D)(3)(e) (iii) of this Chapter, and apportioned accordingly.
(iii) The project sponsor shall submit a
monitoring and verification plan as part of the consistency application that
includes a quality assurance and quality control program associated with
equipment used to determine biogas volumetric flow rate and
CH4 composition. The monitoring and verification plan
shall be specified in accordance with the applicable monitoring requirements
listed in Table 1 below. The monitoring and verification plan shall also
include provisions for ensuring that measuring and monitoring equipment is
maintained, operated, and calibrated based on manufacturer's recommendations,
as well as provisions for the retention of maintenance records for audit
purposes. The monitoring and verification plan shall be certified by an
independent verifier accredited pursuant to subsection 9(E) of this Chapter.
