40 CFR Table 2
Operating Limits
June 9, 2020
As required in §63.5505(b), you must meet the appropriate operating limits in the following table:
Open Table
| For the following control technique . . . | you must . . . |
|---|---|
| 1. condenser | maintain the daily average condenser outlet gas or condensed liquid temperature no higher than the value established during the compliance demonstration. |
| 2. thermal oxidizer | maintain the daily average thermal oxidizer firebox temperature no lower than the value established during the compliance demonstration. |
| 3. water scrubber | maintain the daily average scrubber pressure drop and scrubber liquid flow rate within the range of values established during the compliance demonstration. |
| 4. caustic scrubber | maintain the daily average scrubber pressure drop, scrubber liquid flow rate, and scrubber liquid pH, conductivity, or alkalinity within the range of values established during the compliance demonstration. |
| 5. flare | maintain the presence of a pilot flame. |
| 6. biofilter | maintain the daily average biofilter inlet gas temperature, biofilter effluent pH, and pressure drop within the operating values established during the compliance demonstration. |
| 7. carbon absorber | maintain the regeneration frequency, total regeneration adsorber stream mass or volumetric flow during carbon bed regeneration, and temperature of the carbon bed after regeneration (and within 15 minutes of completing any cooling cycle(s)) for each regeneration cycle within the values established during the compliance demonstration. |
| 8. oil absorber | maintain the daily average absorption liquid flow, absorption liquid temperature, and steam flow within the values established during the compliance demonstration. |
| 9. any of the control techniques specified in this table | if using a CEMS, maintain the daily average control efficiency of each control device no lower than the value established during the compliance demonstration. |
| 10. any of the control techniques specified in this table | a. if you wish to establish alternative operating parameters, submit the application for approval of the alternative operating parameters no later than the notification of the performance test or CEMS performance evaluation or no later than 60 days prior to any other initial compliance demonstration; b. the application must include: information justifying the request for alternative operating parameters (such as the infeasibility or impracticality of using the operating parameters in this final rule); a description of the proposed alternative control device operating parameters; the monitoring approach; the frequency of measuring and recording the alternative parameters; how the operating limits are to be calculated; and information documenting that the alternative operating parameters would provide equivalent or better assurance of compliance with the standard; c. install, operate, and maintain the alternative parameter monitoring systems in accordance with the application approved by the Administrator; d. establish operating limits during the initial compliance demonstration based on the alternative operating parameters included in the approved application; and |
| e. maintain the daily average alternative operating parameter values within the values established during the compliance demonstration. | |
| 11. alternative control technique | a. submit for approval no later than the notification of the performance test or CEMS performance evaluation or no later than 60 days prior to any other initial compliance demonstration a proposed site-specific plan that includes: a description of the alternative control device; test results verifying the performance of the control device; the appropriate operating parameters that will be monitored; and the frequency of measuring and recording to establish continuous compliance with the operating limits; b. install, operate, and maintain the parameter monitoring system for the alternative control device in accordance with the plan approved by the Administrator; |
| c. establish operating limits during the initial compliance demonstration based on the operating parameters for the alternative control device included in the approved plan; and | |
| d. maintain the daily average operating parameter values for the alternative control technique within the values established during the compliance demonstration. |
