NR 440.50(6)(c)5.5. If the owner operator elects to claim an emission allowance for fuel bound nitrogen as described in sub. (3), then concurrently with each reference method run, a representative sample of the fuel used shall be collected and analyzed, following the applicable procedures described in subd. 9. These data shall be used to determine the maximum fuel nitrogen content for which the established water or steam to fuel ratio will be valid.
NR 440.50(6)(c)6.6. If the owner or operator elects to install a CEMS, the performance evaluation of the CEMS may either be conducted separately, as described in subd. 7., or as part of the initial performance test of the affected unit.
NR 440.50(6)(c)7.7. If the owner or operator elects to install and certify a NOx CEMS under sub. (5) (e), then the initial performance test required under s. NR 440.08 may be done in the following alternative manner:
NR 440.50(6)(c)7.a.a. Perform a minimum of 9 reference method runs, with a minimum time per run of 21 minutes, at a single load level, between 90 and 100% of peak, or the highest physically achievable, load.
NR 440.50(6)(c)7.b.b. Use the test data both to demonstrate compliance with the applicable NOx emission limit under sub. (3) and to provide the required reference method data for the RATA of the CEMS described under sub. (5) (b).
NR 440.50(6)(c)7.c.c. The requirement to test at 3 additional load levels is waived.
NR 440.50(6)(c)8.8. If the owner or operator is required under sub. (5) (f) to monitor combustion parameters or parameters indicative of proper operation of NOx emission controls, the appropriate parameters shall be continuously monitored and recorded during each run of the initial performance test, to establish acceptable operating ranges, for purposes of the parameter monitoring plan for the affected unit, as specified in sub. (5) (g).
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.
