| According to the following requirements
|
|---|
| 1. PM or mercury | a. Wet scrubber operating parameters | Establish site-specific minimum scrubber pressure drop and minimum scrubber liquid flow rate operating limits according to § 63.11211(b) | Data from the pressure drop and liquid flow rate monitors and the PM or mercury performance stack tests | (a) You must collect pressure drop and liquid flow rate data every 15 minutes during the entire period of the performance stack tests;
|
| | | | | (b) Determine the average pressure drop and liquid flow rate for each individual test run in the three-run performance stack test by computing the average of all the 15-minute readings taken during each test run.
|
| | b. Electrostatic precipitator operating parameters | Establish a site-specific minimum total secondary electric power operating limit according to § 63.11211(b) | Data from the secondary electric power monitors and the PM or mercury performance stack tests | (a) You must collect secondary electric power data every 15 minutes during the entire period of the performance stack tests;
|
| | | | | (b) Determine the average total secondary electric power for each individual test run in the three-run performance stack test by computing the average of all the 15-minute readings taken during each test run.
|
| 2. Mercury | Dry sorbent or activated carbon injection rate operating parameters | Establish a site-specific minimum sorbent or activated carbon injection rate operating limit according to § 63.11211(b) | Data from the sorbent or activated carbon injection rate monitors and the mercury performance stack tests | (a) You must collect sorbent or activated carbon injection rate data every 15 minutes during the entire period of the performance stack tests;
|
| | | | | (b) Determine the average sorbent or activated carbon injection rate for each individual test run in the three-run performance stack test by computing the average of all the 15-minute readings taken during each test run.
|
| | | | | (c) When your unit operates at lower loads, multiply your sorbent or activated carbon injection rate by the load fraction, as defined in § 63.11237, to determine the required injection rate.
|
| 3. CO | Oxygen | Establish a unit-specific limit for minimum oxygen level | Data from the oxygen analyzer system specified in § 63.11224(a) | (a) You must collect oxygen data every 15 minutes during the entire period of the performance stack tests;
|
| | | | | (b) Determine the average hourly oxygen concentration for each individual test run in the three-run performance stack test by computing the average of all the 15-minute readings taken during each test run.
|
| 4. Any pollutant for which compliance is demonstrated by a performance stack test | Boiler operating load | Establish a unit-specific limit for maximum operating load according to § 63.11212(c) | Data from the operating load monitors (fuel feed monitors or steam generation monitors) | (a) You must collect operating load data (fuel feed rate or steam generation data) every 15 minutes during the entire period of the performance test.
|
| | | | | (b) Determine the average operating load by computing the hourly averages using all of the 15-minute readings taken during each performance test.
|
| | | | | (c) Determine the average of the three test run averages during the performance test, and multiply this by 1.1 (110 percent) as your operating limit. |
