NR 409.04(4)(a)
(a) For gaseous fuel burned during the year, if natural gas is the only gaseous fuel burned, the requirement is assumed to be met.
NR 409.04(4)(b)
(b) For gaseous fuel burned during the year where other gas in addition to or besides natural gas is burned, the requirement is met if the annual average sulfur content is equal to or less than 0.05% by weight. The annual average sulfur content, as a percentage by weight, for the gaseous fuel burned shall be calculated as follows: -
See PDF for diagram 
where:
%Sannual is the annual average sulfur content of the fuel burned during the year by the unit, as a percentage by weight
%Sn is the sulfur content of the nth sample of the fuel delivered during the year to the unit, as a percentage by weight
Vn is the volume of the fuel in a delivery during the year to the unit of which the nth sample is taken, in standard cubic feet; or, for fuel delivered during the year to the unit continuously by pipeline, volume of the fuel delivered starting from when the nth sample of the fuel is taken until the next sample of the fuel is taken, in standard cubic feet
dn is the density of the nth sample of the fuel delivered during the year to the unit, in lb per standard cubic foot
n is each sample taken of the fuel delivered during the year to the unit, taken at least once for each delivery; or, for fuel that is delivered during the year to the unit continuously by pipeline, at least once each quarter during which the fuel is delivered
NR 409.04(4)(c)
(c) For nongaseous fuel burned during the year, the requirement is met if the annual average sulfur content is equal to or less than 0.05% by weight. The annual average sulfur content, as a percentage by weight, shall be calculated using the equation in
par. (b). In lieu of the factor, volume times density, V
nd
n, in the equation, the factor, mass M
n, may be used, where M
n is: mass of the nongaseous fuel in a delivery during the year to the unit of which the nth sample is taken, in pounds; or, for fuel delivered during the year to the unit continuously by pipeline, mass of the nongaseous fuel delivered starting from when the nth sample of the fuel is taken until the next sample of the fuel is taken, in pounds.
