- Table 3 to Subpart JJ of Part 63—Summary of Emission Limits
| Emission point | Existing source | New source | Finishing Operations: | (a) Achieve a weighted average VHAP content across all coatings (maximum kg VHAP/kg solids [lb VHAP/lb solids], as applied | a 1.0 | a 0.8 | (b) Use compliant finishing materials (maximum kg VHAP/kg solids [lb VHAP/lb solids], as applied): | —stains | a 1.0 | a 1.0 | —washcoats | a,b 1.0 | a, b 0.8 | —sealers | a 1.0 | a 0.8 | —topcoats | a 1.0 | a 0.8 | —basecoats | a,b 1.0 | a, b 0.8 | —enamels | a,b 1.0 | a, b 0.8 | —thinners (maximum percent VHAP allowable); or | 10.0 | 10.0 | (c) As an alternative, use control device; or | c 1.0 | c 0.8 | (d) Use any combination of (a), (b), and (c) | 1.0 | 0.8 | Cleaning Operations: | Strippable spray booth material (maximum VOC content, kg VOC/kg solids [lb VOC/lb solids]) | 0.8 | 0.8 | Contact Adhesives: | (a) Use compliant contact adhesives (maximum kg VHAP/kg solids [lb VHAP/lb solids], as applied) based on following criteria: | i. For aerosol adhesives, and for contact adhesives applied to nonporous substrates | d NA | d NA | ii. For foam adhesives used in products that meet flammability requirements | 1.8 | 0.2 | iii. For all other contact adhesives (including foam adhesives used in products that do not meet flammability requirements); or | 1.0 | 0.2 | (b) Use a control device | e 1.0 | e 0.2 | All Finishing Operations and Contact Adhesives: | (a) Achieve total free formaldehyde emissions across all finishing operations and contact adhesives, lb per rolling 12 month period, as applied | 400 | 400 | (b) Use coatings and contact adhesives only if they are low-formaldehyde coatings and contact adhesives | f 1.0 | f 1.0 |

a The limits refer to the VHAP content of the coating, as applied.
b Washcoats, basecoats, and enamels must comply with the limits presented in this table if they are purchased premade, that is, if they are not formulated onsite by thinning other finishing materials. If they are formulated onsite, they must be formulated using compliant finishing materials, i.e., those that meet the limits specified in this table, and thinners containing no more than 3.0 percent VHAP by weight.
c The control device must operate at an efficiency that is equivalent to no greater than 1.0 kilogram (or 0.8 kilogram) of VHAP being emitted from the affected emission source per kilogram of solids used.
d There is no limit on the VHAP content of these adhesives.
e The control device must operate at an efficiency that is equivalent to no greater than 1.0 kilogram (or 0.2 kilogram) of VHAP being emitted from the affected emission source per kilogram of solids used.
f The limits refer to the formaldehyde content by weight of the coating or contact adhesive, as specified on certified product data sheets.
