Table 7 to Subpart IIII of Part 60—Requirements for Performance Tests for Stationary CI ICE With a Displacement of ≥30 Liters per Cylinder
As stated in § 60.4213, you must comply with the following requirements for performance tests for stationary CI ICE with a displacement of ≥30 liters per cylinder:

Each
Complying with the requirement to
You must
Using
According to the following requirements
1. Stationary CI internal combustion engine with a displacement of ≥ 30 liters per cylinder
a. Reduce NOX emissions by 90 percent or more;
i. Select the sampling port location and number/location of traverse points at the inlet and outlet of the control device;
(a) For NOX, O2, and moisture measurement, ducts ≤6 inches in diameter may be sampled at a single point located at the duct centroid and ducts >6 and ≤12 inches in diameter may be sampled at 3 traverse points located at 16.7, 50.0, and 83.3% of the measurement line ('3-point long line'). If the duct is >12 inches in diameter and the sampling port location meets the two and half-diameter criterion of Section 11.1.1 of Method 1 of 40 CFR part 60, appendix A-1, the duct may be sampled at '3-point long line'; otherwise, conduct the stratification testing and select sampling points according to Section 8.1.2 of Method 7E of 40 CFR part 60, appendix A-4.

ii. Measure O2 at the inlet and outlet of the control device;
(1) Method 3, 3A, or 3B of 40 CFR part 60, appendix A-2
(b) Measurements to determine O2 concentration must be made at the same time as the measurements for NOX concentration.

iii. If necessary, measure moisture content at the inlet and outlet of the control device; and
(2) Method 4 of 40 CFR part 60, appendix A-3, Method 320 of 40 CFR part 63, appendix A, or ASTM D 6348-03 (incorporated by reference, see § 60.17)
(c) Measurements to determine moisture content must be made at the same time as the measurements for NOX concentration.

iv. Measure NOX at the inlet and outlet of the control device.
(3) Method 7E of 40 CFR part 60, appendix A-4, Method 320 of 40 CFR part 63, appendix A, or ASTM D 6348-03 (incorporated by reference, see § 60.17)
(d) NOX concentration must be at 15 percent O2, dry basis. Results of this test consist of the average of the three 1-hour or longer runs.

b. Limit the concentration of NOX in the stationary CI internal combustion engine exhaust.
i. Select the sampling port location and number/location of traverse points at the exhaust of the stationary internal combustion engine;

If the duct is >12 inches in diameter and the sampling port location meets the two and half-diameter criterion of Section 11.1.1 of Method 1 of 40 CFR part 60, appendix A-1, the duct may be sampled at '3-point long line'; otherwise, conduct the stratification testing and select sampling points according to Section 8.1.2 of Method 7E of 40 CFR part 60, appendix A-4.

ii. Determine the O2 concentration of the stationary internal combustion engine exhaust at the sampling port location;
(1) Method 3, 3A, or 3B of 40 CFR part 60, appendix A-2
(b) Measurements to determine O2 concentration must be made at the same time as the measurement for NOX concentration.

iii. If necessary, measure moisture content of the stationary internal combustion engine exhaust at the sampling port location; and
(2) Method 4 of 40 CFR part 60, appendix A-3, Method 320 of 40 CFR part 63, appendix A, or ASTM D 6348-03 (incorporated by reference, see § 60.17)
(c) Measurements to determine moisture content must be made at the same time as the measurement for NOX concentration.

iv. Measure NOX at the exhaust of the stationary internal combustion engine; if using a control device, the sampling site must be located at the outlet of the control device.
(3) Method 7E of 40 CFR part 60, Appendix A-4, Method 320 of 40 CFR part 63, appendix A, or ASTM D 6348-03 (incorporated by reference, see § 60.17)
(d) NOX concentration must be at 15 percent O2, dry basis. Results of this test consist of the average of the three 1-hour or longer runs.

c. Reduce PM emissions by 60 percent or more
i. Select the sampling port location and the number of traverse points;
(1) Method 1 or 1A of 40 CFR part 60, appendix A-1
