Performance Test Requirements for HCl Production Affected Sources
June 9, 2020
As stated in §63.9020, you must comply with the following requirements for performance tests for HCl production for each affected source.
Open Table
| For each HCl process vent and each HCl storage tank and HCl transfer operation for which you are conducting a performance test, you must . . . | Using . . . | Additional Information . . . |
|---|---|---|
| 1. Select sampling port location(s) and the number of traverse points | a. Method 1 or 1A in appendix A to 40 CFR part 60 of this chapter | i. If complying with a percent reduction emission limitation, sampling sites must located at the inlet and outlet of the control device prior to any releases to the atmosphere (or, if a series of control devices are used, at the inlet of the first control device and at the outlet of the final control device prior to any releases to the atmosphere); or |
| ii. If complying with an outlet concentration emission limitation, the sampling site must be located at the outlet of the final control device and prior to any releases to the atmosphere or, if no control device is used, prior to any releases to the atmosphere. | ||
| 2. Determine velocity and volumetric flow rate | Method 2, 2A, 2C, 2D, 2F, or 2G in appendix A to 40 CFR part 60 of this chapter. | |
| 3. Determine gas molecular weight | a. Not applicable | i. Assume a molecular weight of 29 (after moisture correction) for calculation purposes. |
| 4. Measure moisture content of the stack gas | Method 4 in appendix A to 40 CFR part 60 of this chapter. | |
| 5. Measure HCl concentration and Cl2 concentration from HCl process vents | a. Method 26A in appendix A to 40 CFR part 60 of this chapter | i. An owner or operator may be exempted from measuring the Cl2 concentration from an HCl process vent provided that a demonstration that Cl2 is not likely to be present in the stream is submitted as part of the site-specific test plan required by §63.9020(a)(2). This demonstration may be based on process knowledge, engineering judgment, or previous test results. |
| 6. Establish operating limits with which you will demonstrate continuous compliance with the emission limits in Table 1 to this subpart, in accordance with §63.9020(e)(1) or (2). |
