(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 Lolo, and four thousand parts per million
			 by volume as hexane for the CNMOC. 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, MNMOC = total NMOC emission rate from the landfill,
				megagrams 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
ti = age of the ith section, years
CNMOC = concentration of NMOC, parts per million by volume as
				hexane 3.6 X 10-9 = conversion factor
The mass of nondegradable solid waste may be subtracted from
				the total mass of solid waste in a particular section of the landfill when
				calculating the value for Mi if documentation of the nature and amount of such
				wastes is maintained.
(b)
			 The following equation shall be used if the actual year-to-year solid waste
			 acceptance rate is unknown.
MNMOC = 2LoR (e-kc-e-kt) (CNMOC) ( 3.6 x 10-9)
Where,
MNMOC= mass emission rate of NMOC, megagrams 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 landfill, years
CNMOC = 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.
