(ii) Any nonproductive area of the landfill may be excluded from control, provided that the total of all excluded areas can be shown to contribute less than 1 percent of the total amount of NMOC emissions from the landfill. The amount, location, and age of the material shall be documented and provided to the Administrator upon request. A separate NMOC emissions estimate shall be made for each section proposed for exclusion, and the sum of all such sections shall be compared to the NMOC emissions estimate for the entire landfill. Emissions from each section shall be computed using the following equation: Qi = 2 k Lo Mi (e-kt i) (CNMOC) (3.6 * 10-9)
where,
Qi = NMOC emission rate from the ith section, megagrams per year
k = methane generation rate constant, year-1
Lo = methane generation potential, cubic meters per megagram solid waste
Mi = mass of the degradable solid waste in the ith section, megagram
ti = age of the solid waste in the ith section, years
CNMOC = concentration of nonmethane organic compounds, parts per million by volume
3.6 * 10-9 = conversion factor
