Pt. 63, Subpt. DDDDD, Table 7
Table 7 to Subpart DDDDD of Part 63—Establishing Operating Limits
As stated in § 63.7520, you must comply with the following requirements for establishing operating limits:
If you have an applicable emission limit for . . .
And your operating limits are based on . . .
You must . . .
Using . . .
According to the following requirements
1. Particulate matter, mercury, or total selected metals
a. Wet scrubber operating parameters
i. Establish a site-specific minimum pressure drop and minimum flow rate operating limit according to § 63.7530(c)
(1) Data from the pressure drop and liquid flow rate monitors and the particulate matter, mercury, or total selected metals performance test
(a) You must collect pressure drop and liquid flow-rate data every 15 minutes during the entire period of the performance tests;
(b) Determine the average pressure drop and liquid flow-rate for each individual test run in the three-run performance test by computing the average of all the 15-minute readings taken during each test run.
b. Electrostatic precipitator operating parameters (option only for units with additional wet scrubber control)
i. Establish a site-specific minimum voltage and secondary current or total power input according to § 63.7530(c)
(1) Data from the pressure drop and liquid flow rate monitors and the particulate matter, mercury, or total selected metals performance test
(a) You must collect voltage and secondary current or total power input data every 15 minutes during the entire period of the performance tests;
(b) Determine the average voltage and secondary current or total power input for each individual test run in the three-run performance test by computing the average of all the 15-minute readings taken during each test run.
2. Hydrogen Chloride
a. Wet scrubber operating parameters
i. Establish a site-specific minimum pressure drop and minimum flow rate operating limit according to § 63.7530(c)
(1) Data from the pH, pressure drop, and liquid flow-rate monitors and the hydrogen chloride performance test
(a) You must collect pH, pressure drop, and liquid flow-rate data every 15 minutes during the entire period of the performance tests;
(b) Determine the average pH, pressure drop, and liquid flow-rate for each individual test run in the three-run performance test by computing the average of all the 15-minute readings taken during each test run.
b. Dry scrubber operating parameters
i. Establish a site-specific minimum sorbent injection rate operating limit according to § 63.7530(c)
(1) Data from the sorbent injection rate monitors and hydrogen chloride performance test
(a) You must collect sorbent injection rate data every 15 minutes during the entire period of the performance tests;
(b) Determine the average sorbent injection rate for each individual test run in the three-run performance test by computing the average of all the 15-minute readings taken during each test run.
