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: Table 7_to Subpart WWWW of Part 63._Options Allowing Use of the Same Resin Across Different Operations That Use the Same Resin Type ------------------------------------------------------------------------ The highest resin weight is* * * percent organic HAP If your facility has the following content, or weighted resin type and application method average weight is . . .
. . . percent organic HAP content, you can use for . . .
------------------------------------------------------------------------ 1. CR/HS resins, centrifugal a. CR/HS mechanical. \3\ 48.0 casting 1 2.
b. CR/HS filament 48.0 application.

b. CR/HS manual..... 46.4 ------------------------------------------------------------------------ 3. CR/HS resins, filament CR/HS manual........ 42.0 application.
------------------------------------------------------------------------ 4. non-CR/HS resins, filament a. non-CR/HS \3\ 45.0 application. mechanical.
b. non-CR/HS manual. 45.0 c. non-CR/HS 45.0 centrifugal casting 1 2.
------------------------------------------------------------------------ 5. non-CR/HS resins, nonatomized a. non-CR/HS manual. 38.5 mechanical.
b. non-CR/HS 38.5 centrifugal casting 1 2.
6. non-CR/HS resins, centrifugal non-CR/HS manual.... 37.5 casting 1 2.
7. tooling resins, nonatomized tooling manual...... 91.4 mechanical.
8. tooling resins, manual......... tooling atomized 45.9 mechanical.
------------------------------------------------------------------------ \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.
