Section Env-A 805.06 - Alternate CE Procedures for Solvent Recovery Systems

For a source that uses a control device, such as a carbon adsorber, designed to collect and recover VOC in accordance with the criteria in Env-A 805.07, the following alternative to CE testing may be used:

(a) The overall control efficiency of the system shall be determined over a minimum of a 24-hour period;

(b) The testing procedures shall be as described in 40 CFR 60.433, with the following additional restrictions for VOC sources subject to Env-A 1204 or successor rules in Env-A 1200:

(1) The owner or operator of the source shall compare solvent usage to solvent recovery on a 24-hour basis, rather than a 30-day weighted average as specified in 40 CFR 60.433; or

(2) If the overall emission reduction efficiency required by the applicable rule is met, as determined by the initial 24-hour test, the owner or operator of the source may compare solvent usage to solvent recovery over an alternative time period subject to the following:

a. The owner or operator seeking approval of an alternative time period shall submit the following information in writing to the department:

1. The identity and description of the facility, including a description of the process and the solvent recovery control device;

2. The proposed alternative time period, not to exceed 30 days; and

3. Technical data and information demonstrating that the control device designed to collect and recover VOC will be operated in a manner consistent with the manner in which it was operated during the initial 24-hour period of the test, and that the results produced over the proposed time period are no less precise and accurate than those produced during the initial 24-hour time period;

b. The department shall review the information submitted pursuant to (b)(2)a., above;

c. The department shall approve the proposed alternative time period if all of the information required in (b)(2)a., above, has been submitted to the department and the information demonstrates that:

1. The control device shall be operated in a manner consistent with the manner in which it was operated during the initial 24-hour time period of the test; and

2. The results produced over the proposed time period shall be no less precise and accurate than those produced during the initial 24-hour time period; and

d. The department shall notify the applicant and the EPA of the decision within 60 days of receipt of the required information;

(c) Each demonstration as specified in (b)(1), above, relating solvent usage with solvent recovery, including the initial 24-hour time period, shall be performed by the source within 72 hours of the end of each established time period; and

(d) Any recovery rates calculated using the procedure specified in this section, which result in a lower rate than that needed to comply with the applicable rule, shall be reported to the department within 7 calendar days.
