				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 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.
