± 5% at 30, 50, 75 and 90-to-100% of peak load or at 4 evenly-spaced load points in the normal operating range of the gas turbine, including the minimum point in the operating range and 90-to-100% of peak load, or at the highest achievable load point if 90-to-100% of peak load cannot be physically achieved in practice. If the turbine combusts both oil and gas as primary or backup fuels, separate performance testing is required for each fuel. Notwithstanding these requirements, performance testing is not required for any emergency fuel, as defined in
sub. (2) (e).
NR 440.50(6)(c)3.
3. For a combined cycle turbine system with supplemental heat (duct burner), the owner or operator may elect to measure the turbine NO

x emission limit in
sub. (3) for the combustion turbine shall still be met.
NR 440.50(6)(c)4.
4. If water or steam injection is used to control NO
x with no additional post-combustion NO
x control and the owner or operator chooses to monitor the steam or water to fuel ratio in accordance with
sub. (5) (a), then that monitoring system shall be operated concurrently with each EPA Method 20, ASTM D6522-00, incorporated by reference in
s. NR 440.17 (2) (a) 70., or Method 7E run and shall be used to determine the fuel consumption and the steam or water to fuel ratio necessary to comply with the applicable
sub. (3) NO
x emission limit.
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 NO
x 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.

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

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.

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.
