As required in § 63.5850 you must conduct performance tests, performance evaluations, and design evaluation according to the requirements in the following table:
| For . . .
| You must . . .
| Using . . .
| According to the following requirements . . .
|
|---|
| 1. Each enclosure used to collect and route organic HAP emissions to an add-on control device that is a PTE | Meet the requirements for a PTE | EPA method 204 of appendix M of 40 CFR part 51 | Enclosures that meet the requirements of EPA Method 204 of appendix M of 40 CFR part 51 for a PTE are assumed to have a capture efficiency of 100%. Note that the criteria that all access doors and windows that are not treated as natural draft openings shall be closed during routine operation of the process is not intended to require that these doors and windows be closed at all times. It means that doors and windows must be closed any time that you are not actually moving parts or equipment through them. Also, any styrene retained in hollow parts and liberated outside the PTE is not considered to be a violation of the EPA Method 204 criteria.
|
| 2. Each enclosure used to collect and route organic HAP emissions to an add-on control device that is not a PTE | a. Determine the capture efficiency of each enclosure used to capture organic HAP emissions sent to an add-on control device | i. EPA methods 204B through E of appendix M of 40 CFR part 51, or | (1) Enclosures that do not meet the requirements for a PTE must determine the capture efficiency by constructing a temporary total enclosure according to the requirements of EPA Method 204 of appendix M of 40 CFR part 51 and measuring the mass flow rates of the organic HAP in the exhaust streams going to the atmosphere and to the control device. Test runs for EPA Methods 204B through E of appendix M of 40 CFR part 51 must be at least 3 hours.
|
| | | ii. An alternative test method that meets the requirements in 40 CFR part 51, appendix M | (1) The alternative test method must the data quality objectives and lower confidence limit approaches for alternative capture efficiency protocols requirements contained in 40 CFR part 63 subpart KK, appendix A.
|
| 3. Each control device used to comply with a percent reduction requirement, or an organic HAP emissions limit | Determine the control efficiency of each control device used to control organic HAP emissions | The test methods specified in § 63.5850 to this subpart | Testing and evaluation requirements are contained in 40 CFR part 63, subpart SS, and § 63.5850 to this subpart.
|
| 4. Determining organic HAP emission factors for any operation | Determine the mass organic HAP emissions rate | The test methods specified in § 63.5850 to this subpart | Testing and evaluation requirements are contained in 40 CFR part 63, subpart SS, and § 63.5850 to this subpart. |
