# §63.9515. How do I demonstrate initial compliance with the emission limitation that applies to me?

- (a) You have demonstrated initial compliance for each new, reconstructed, or existing large solvent mixer subject to the emission limitation in [§ 63.9500(a)](/cfr/40/63.9500.md?p=a) if the HAP solvent discharged to the atmosphere during the first 7 days after the compliance date, determined according to the provisions in [§ 63.9520](/cfr/40/63.9520.md), does not exceed a 7-day block average of 30 percent of that which would otherwise be emitted in the absence of solvent recovery and/or solvent substitution.
- (b) You have demonstrated initial compliance for each new, reconstructed, or existing small solvent mixer subject to the emission limitation in [§ 63.9500(b)](/cfr/40/63.9500.md?p=b) if the HAP solvent discharged to the atmosphere during the first 7 days after the compliance date, determined according to the provisions in [§ 63.9520](/cfr/40/63.9520.md), does not exceed a 7-day block average of 15 percent of that which would otherwise be emitted in the absence of solvent recovery and/or solvent substitution.
- (c) You must submit a notification of compliance status containing the results of the initial compliance demonstration according to [§ 63.9535(e)](/cfr/40/63.9535.md?p=e).
