NR 440.50(6)(c)9.9. To determine the fuel bound nitrogen content of fuel being fired if an emission allowance is claimed for fuel bound nitrogen, the owner or operator may use equipment and procedures meeting the requirements of the following:
NR 440.50(6)(c)9.a.a. For liquid fuels, ASTM D2597-94 (reapproved 1999), D4629-02, D5762-02 or D6366-99, incorporated by reference in s. NR 440.17 (2) (a) 33., 60., 66. and 70., respectively.
NR 440.50(6)(c)9.b.b. For gaseous fuels, analytical methods and procedures that are accurate to within 5% of the instrument range and are approved by the department.
NR 440.50(6)(c)10.10. If the owner or operator is required under sub. (5) (i) 1. or 3 to periodically determine the sulfur content of the fuel combusted in the turbine, a minimum of 3 fuel samples shall be collected during the performance test. The samples shall be analyzed for the total sulfur content of the fuel using:
NR 440.50(6)(c)10.a.a. For liquid fuels, ASTM D129–00, D1266–98, D1552–01, D2622–98, D4294–02 or D5453–00, incorporated by reference in s. NR 440.17 (2) (a) 8., 18., 20., 34., 55. and 64., respectively.
NR 440.50(6)(c)10.b.b. For gaseous fuels, ASTM D1072–90 (Reapproved 1994), D3246–96, D4468–85 (Reapproved 2000) or D6667–01, incorporated by reference in s. NR 440.17 (2) (a) 15., 44., 59. and 72., respectively. The applicable ranges of some of the ASTM methods are not adequate to measure the levels of sulfur in some fuel gases. Dilution of samples before analysis, with verification of the dilution ratio, may be used, subject to the prior approval of the department.
NR 440.50(6)(c)11.11. The fuel analyses required under subds. 9. and 10. may be performed by the owner or operator, a service contractor retained by the owner or operator, the fuel vendor, or any other qualified agency.
NR 440.50(6)(d)(d) The owner or operator may use the following as alternatives to the reference methods and procedures specified in this subsection:
NR 440.50(6)(d)1.1. Instead of using the equation in par. (c) 1., manufacturers may develop ambient condition correction factors to adjust the nitrogen oxides emission level measured by the performance test as provided in s. NR 440.08 to ISO standard day conditions.
