  • Table 7 to Subpart WWWW of Part 63 - Options Allowing Use of the Same Resin Across Different Operations That Use the Same Resin Type

    As specified in § 63.5810(d), when electing to use the same resin(s) for multiple resin application methods, you may use any resin(s) with an organic HAP content less than or equal to the values shown in the following table, or any combination of resins whose weighted average organic HAP content based on a 12-month rolling average is less than or equal to the values shown the following table:

    If your facility has the following resin type and application method . . . The highest resin weight is* * * percent organic HAP content, or weighted average weight percent organic HAP content, you can use for . . . is . . .
    1. CR/HS resins, centrifugal casting1 2 a. CR/HS mechanical 3 48.0
    b. CR/HS filament application 48.0
    c. CR/HS manual 48.0
    2. CR/HS resins, nonatomized mechanical a. CR/HS filament application 46.4
    b. CR/HS manual 46.4
    3. CR/HS resins, filament application CR/HS manual 42.0
    4. non-CR/HS resins, filament application a. non-CR/HS mechanical 3 45.0
    b. non-CR/HS manual 45.0
    c. non-CR/HS centrifugal casting1 2 45.0
    5. non-CR/HS resins, nonatomized mechanical a. non-CR/HS manual 38.5
    b. non-CR/HS centrifugal casting1 2 38.5
    6. non-CR/HS resins, centrifugal casting1 2 non-CR/HS manual 37.5
    7. tooling resins, nonatomized mechanical tooling manual 91.4
    8. tooling resins, manual tooling atomized mechanical 45.9

    1 If the centrifugal casting operation blows heated air through the molds, then 95 percent capture and control must be used if the facility wishes to use this compliance option.

    2 If the centrifugal casting molds are not vented, the facility may treat the centrifugal casting operations as if they were vented if they wish to use this compliance option.

    3 Nonatomized mechanical application must be used.
