17. Who is not covered? (Cont’d.) • Surface coating subject to any other NESHAP in Part 63; • Janitorial or building and facility maintenance operations;

18. What Standards Require Compliance? (63.5120) • If the effected source is existing OR new • HAP emissions are limited to no more than… • OPTION 1: • 2% of the organic HAP applied during each month of the 12-month compliance period (98% reduction)

19. What Standards Require Compliance? (63.5120) Cont’d. • OPTION 2 & 4: • 0.046kg organic HAP/liter coating solids applied during each 12-month compliance period

20. What Standards Require Compliance? (63.5120) Cont’d. • OPTION 3: • 20 parts per million by volume on a dry basis when an oxidizer is used in combination with a capture system that achieves 100% capture

21. Options • The effected source may apply any of the compliance options to an individual coil coating line, or • to multiple lines as a group, or • to the entire affected source.

22. Options (cont’d.) • The effected source may use different compliance options for different coil coating lines, or • At different times on the same line.

23. Options (cont’d.) • However, the source may not use different compliance options at the same time on the same coil coating line. • If the source switches between compliance options for any coil coating line or group of lines, you must document this switch as required by § 63.5190(a), and

24. Options (cont’d.) • The source must report it in the next semiannual compliance report required in§ 63.5180.

25. Operating Limits • Operating limits are the site-specific parameter limits determined by the capture and control devices during the performance test. • The source operating limits must be monitored by a continuous parameter monitoring system (CPMS)

26. Important dates • The final rule was published on June 10, 2002, under 67 FR 39794,

27. Important dates (cont’d.) • Existing major sources (ON OR BEFORE July 18, 2000 ) must comply with: • Emissions limitations; • Operation & Maintenance requirement; • Major source status determination; no later than, June 10, 2005.

28. Important Dates (cont’d.) • New effected sources operating after July, 18, 2000, must comply with the regulatory requirements by June 10, 2002 or upon initial startup of the effected sources whichever is later.

40. General Compliance (cont’d.) • The outlet organic HAP concentration must be no greater • Than 20 parts per million (ppm) by volume on a dry basis.

41. General Compliance (cont’d.) • Initial Compliance Requirements (§63.5180) • Additional Performance Test Requirements (§63.5180)

42. Compliance Calculations (§63.5170) • For Compliance Options #1, #2 and #4, the collected data for regulated materials are used to calculate the organic HAP • Content of each material used during the 12-month rolling average compliance period.
