Table 2 to Subpart UUUU of Part 63—Operating Limits

As required in §63.5505(b), you must meet the appropriate operating limits in the following table:

For the following control technique .  .  .you must .  .  .
1. condensermaintain the daily average condenser outlet gas or condensed liquid temperature no higher than the value established during the compliance demonstration.
2. thermal oxidizera. for periods of normal operation, maintain the daily average thermal oxidizer firebox temperature no lower than the value established during the compliance demonstration;
   b. after December 29, 2020, for existing sources (and new or reconstructed sources for which construction or reconstruction commenced on or before September 9, 2019), and on July 2, 2020, or immediately upon startup, whichever is later for new or reconstructed sources for which construction or reconstruction commenced after September 9, 2019, maintain documentation for periods of startup demonstrating that the oxidizer was properly operating (e.g., firebox temperature had reached the setpoint temperature) prior to emission unit startup.
3. water scrubbera. for periods of normal operation, maintain the daily average scrubber pressure drop and scrubber liquid flow rate within the range of values established during the compliance demonstration;
   b. after December 29, 2020, for existing sources (and new or reconstructed sources for which construction or, reconstruction commenced on or before September 9, 2019), and on July 2, 2020, or immediately upon startup, whichever is later for new or reconstructed sources for which construction or reconstruction commenced after September 9, 2019, maintain documentation for periods of startup and shutdown to confirm that the scrubber is operating properly prior to emission unit startup and continues to operate properly until emission unit shutdown is complete. Appropriate startup and shutdown operating parameters may be based on equipment design, manufacturer's recommendations, or other site-specific operating values established for normal operating periods.
4. caustic scrubbera. for periods of normal operation, 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;
   b. after December 29, 2020, for existing sources (and new or reconstructed sources for which construction or reconstruction commenced on or before September 9, 2019), and on July 2, 2020, or immediately upon startup, whichever is later for new or reconstructed sources for which construction or reconstruction commenced after September 9, 2019, maintain documentation for periods of startup and shutdown to confirm that the scrubber is operating properly prior to emission unit startup and continues to operate properly until emission unit shutdown is complete. Appropriate startup and shutdown operating parameters may be based on equipment design, manufacturer's recommendations, or other site-specific operating values established for normal operating periods.
5. flaremaintain the presence of a pilot flame.
6. biofiltermaintain the daily average biofilter inlet gas temperature, biofilter effluent pH or conductivity, and pressure drop within the operating values established during the compliance demonstration.
7. carbon absorbermaintain 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 absorbermaintain 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 tableif 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 tablea. 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 techniquea. 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.
