(2) For the emissions limit in [§ 63.7925(d)(2)](/cfr/40/63.7925.md?p=d-2), the concentration of total HAP listed in Table 1 of this subpart or TOC (minus methane and ethane) from the combustion control device, measured by a performance test or determined by a design evaluation according to the procedures in [§ 63.7941](/cfr/40/63.7941.md), do not exceed 20 ppmv on a dry basis corrected to 3 percent oxygen. - (d) You must demonstrate initial compliance of each control device subject to operating limits in [§ 63.7925(g)](/cfr/40/63.7925.md?p=g) with the applicable limits if you have submitted as part of your notification of compliance status, specified in [§ 63.7950](/cfr/40/63.7950.md), a signed statement that you have met the requirements in paragraphs [(d)(1)](#d-1) and [(2)](#d-2) of this section. - (1) You have established an appropriate operating limit(s) for each of the operating parameter applicable to your control device as specified in [§ 63.7925(g)(1) through (6)](/cfr/40/63.7925.md?p=g-1..g-6). - (2) You have a record of the applicable operating parameter data during the performance test or design evaluation during which the emissions met the applicable limit. - (e) You must demonstrate initial compliance with the spent carbon replacement and disposal work practice standards for carbon adsorption systems in [§ 63.7925(h)](/cfr/40/63.7925.md?p=h) if you have submitted as part of your notification of compliance status, specified in [§ 63.7950](/cfr/40/63.7950.md), a signed statement that you will comply with each work practice standard that applies to your carbon adsorption system. - (f) You must demonstrate initial compliance with the catalyst replacement work practice standards for catalytic incinerators in [§ 63.7925(i)](/cfr/40/63.7925.md?p=i) if you have submitted as part of your notification of compliance status, specified in [§ 63.7950](/cfr/40/63.7950.md), a signed statement that you will comply with the specified work practice standard. -
