(a) Methods to determine the mass percent of HAP in cements and solvents. To determine the HAP content in the cements and solvents used at your tire production affected source, use EPA Method 311 of appendix A of this part, an approved alternative method, or any other reasonable means for determining the HAP content of your cements and solvents. Other reasonable means include, but are not limited to: a material safety data sheet (MSDS), provided it contains appropriate information; a certified product data sheet (CPDS); or a manufacturer's hazardous air pollutant data sheet. You are not required to test the materials that you use, but the Administrator may require a test using EPA Method 311 (or an approved alternative method) to confirm the reported HAP content. If the results of an analysis by EPA Method 311 are different from the HAP content determined by another means, the EPA Method 311 results will govern compliance determinations.
(b) Methods to demonstrate compliance with the HAP constituent emission limits in Table 1 to this subpart (option 1). Use the method in paragraph (b)(1) of this section to demonstrate initial and continuous compliance with the applicable emission limits for tire production affected sources using the compliance alternative described in Sec. 63.5985(a), purchase alternative. Use the equations in paragraphs (b)(2) and (3) of this section to demonstrate initial and continuous compliance with the emission limits for tire production affected sources using the monthly average compliance alternatives described in Sec. 63.5985(b) and (c).
(1) Determine the mass percent of each HAP in each cement and solvent according to the procedures in paragraph (a) of this section.
(2) Use Equation 1 of this section to calculate the HAP emission rate for each monthly operating period when complying by using cements and solvents without using an add-on control device so that the monthly average HAP emissions do not exceed the HAP constituent emission limits in Table 1 to this subpart, option 1. Equation 1 follows:[GRAPHIC] [TIFF OMITTED] TR09JY02.000 Where: Emonth = mass of the specific HAP emitted per total mass

control device during all operating days.HAPk = mass percent, expressed as a decimal, of the specific
HAP in cement and solvent k, as purchased, for cements and
solvents used in the month in processes that are routed to a
control device during non-control operating days, which are
defined as days when either the control system is not
operating within the operating range established during the
performance test or when monitoring data are not collected.TMASSk = total mass of cement and solvent k used in the month
in processes that are routed to a control device during all
non-control operating days, grams.p=number of cements and solvents used in the month that are routed to a

(4) Each monthly calculation is a compliance demonstration for the purpose of this subpart.
(c) Methods to demonstrate compliance with the production-based emission limits in Table 1 to this subpart, option 2.

(5) Each monthly calculation is a compliance demonstration for the purpose of this subpart.
(d) Specific compliance demonstration requirements for tire production affected sources. (1) Conduct any required compliance demonstration according to the requirements in Sec. 63.5993.
(1) Conduct any required compliance demonstration according to the requirements in Sec. 63.5993.
(2) If you are demonstrating compliance with the HAP constituent option in Table 1 to this subpart, option 1, conduct the compliance demonstration using cements and solvents that are representative of cements and solvents typically used at your tire production affected source.
(3) Establish an operating range that corresponds to the control efficiency as described in Table 5 to this subpart.
(e) How to take credit for HAP emissions reductions from add-on control devices. If you want to take credit in Equations 2 and 4 of this section for HAP emissions reduced using a control system, you must meet the requirements in paragraphs (e)(1) and (2) of this section.
(1) Monitor the established operating parameters as appropriate.
(i) If you use a thermal oxidizer, monitor the firebox secondary chamber temperature.
(ii) If you use a carbon adsorber, monitor the total regeneration stream mass or volumetric flow for each regeneration cycle, and the carbon bed temperature after each regeneration, and within 15 minutes of completing any cooling cycle.
(iii) If you use a control device other than a thermal oxidizer or a regenerative carbon adsorber, install and operate a continuous parameter monitoring system according to your site-specific performance test plan submitted according to Sec. 63.7(c)(2)(i).
(iv) If you use a permanent total enclosure, monitor the face velocity across the natural draft openings (NDO) in the enclosure. Also, if you use an enclosure, monitor to ensure that the sizes of the NDO have not changed, that there are no new NDO, and that a HAP emission source has not been moved closer to an NDO since the last compliance demonstration was conducted.
(v) If you use other capture systems, monitor the parameters identified in your monitoring plan.
(2) Maintain the operating parameters within the operating range established during the compliance demonstration.
(f) How to take credit for HAP emissions reductions when streams are combined. When performing material balances to demonstrate compliance, if the storage of materials, exhaust, or the wastewater from more than one affected source are combined at the point where control systems are applied, any credit for emissions reductions needs to be prorated among the affected sources based on the ratio of their contribution to the uncontrolled emissions.
