Reference Test Method for Nitrogen Oxide Emissions Clause Samples

Reference Test Method for Nitrogen Oxide Emissions. Whenever compliance emission testing is required, US EPA Methods 7 shall be used to demonstrate compliance. [s. NR 439.06(6), Wis. Adm. Code] (b) The permittee shall maintain records at the source that indicate stacks S12, S13, S14, and S15 have unobstructed vertical flow. [s. NR 439.04(1)(d), Wis. Adm. Code] 38 These more restrictive limitations are necessary to ensure the National Ambient Air Quality Standards for particulate matter are attained and maintained. 39 Because the emission limitations listed in I.B.2.b.(1)(a) are equal to the maximum theoretical emissions for each boiler while firing these fuels, limiting the type of fuel used is adequate to demonstrate compliance with the particulate matter emission limit. Maximum theoretical particulate matter emissions were calculated using an emission factor of 7.6 pounds per million cubic feet of natural gas fired from AP-42, 5th edition, ch. 1.4. 41 It is not expected that the visible emission limitation of 40% opacity would be exceeded while firing these fuels. Therefore restricting the type of fuel used is adequate to ensure compliance with the emission limitation. 43 This requirement is necessary to ensure that the National Ambient Air Quality Standards for nitrogen oxides are attained and maintained.
