(a) Percent reduction for formaldehyde. To determine compliance with the percent reduction formaldehyde emission standard, use equation 1 of this section as follows:[GRAPHIC] [TIFF OMITTED] TR11AP02.021 Where: Ef = Formaldehyde control efficiency, percent.Mi = Mass flow rate of formaldehyde entering the control
device, kilograms (pounds) per hour.Mo = Mass flow rate of formaldehyde exiting the control
device, kilograms (pounds) per hour.
(b) Formaldehyde mass emissions rate. To determine compliance with the kilogram per megagram (pound per ton) formaldehyde emission standard, use equation 2 of this section as follows:[GRAPHIC] [TIFF OMITTED] TR11AP02.022 Where: E = Formaldehyde mass emissions rate, kilograms (pounds) of formaldehyde
per megagram (ton) of fiberglass mat produced.M = Formaldehyde mass emissions rate, kilograms (pounds) per hour.P = The wet-formed fiberglass mat production rate during the emissions
sampling period, including any material trimmed from the final
product, megagrams (tons) per hour.
(c) Urea-formaldehyde (UF) resin solids application rate. To determine the UF resin solids application rate, use equation 3 of this section as follows: [GRAPHIC] [TIFF OMITTED] TR11AP02.023 Where: UF solids/hour = UF resin solids application rate (pounds per hour).LOI = loss on ignition (weight faction), or pound of organic binder per
pound of mat.UFL = UF-to-latex ratio in the binder (mass fraction of UF resin solids
in total combined resin solids for UF and latex), or pound of
UF solids per pound of total resin solids (UF and latex).MW = weight of the final mat per square (pounds per roofing square).SQ = roofing squares produced per hour.
