(2) The written site-specific plan must be maintained onsite at the facility and is enforceable upon the compliance date specified in § 63.2233.

(a) You must conduct performance tests upon initial startup or no later than 180 calendar days after the compliance date that is specified for your source in § 63.2233 and according to § 63.7(a)(2), whichever is later.

(b) You must designate and clearly identify each hardwood veneer dryer. Submit with the Notification of Compliance Status the annual volume percentage of softwood species dried in the dryer based on your dryer production for the 12 months prior to the compliance date specified for your source in § 63.2233. If you did not dry any softwood species in the dryer during the 12 months prior to the compliance date, then you need only to submit a statement indicating that no softwood species were dried. In addition, submit with the Notification of Compliance Status a signed statement by a responsible official that certifies with truth, accuracy, and completeness that the veneer dryer will be used to process less than 30 volume percent softwood species in the future.

(e) You must install, operate, certify and maintain each COMS according to the procedures in paragraphs (e)(1) through (7) of this section by the compliance date specified in § 63.2233.

(1) Each COMS must be installed, operated, and maintained according to Performance Specification 1 at appendix B to part 60 of this chapter.

(2) You must conduct a performance evaluation of each COMS according to the requirements in § 63.8(e) and according to Performance Specification 1 at appendix B to part 60 of this chapter.

(3) As specified in § 63.8(c)(4)(i), each COMS must complete a minimum of one cycle of sampling and analyzing for each successive 10-second period and one cycle of data recording for each successive 6-minute period.

(4) The COMS data must be reduced as specified in §§ 63.8(g)(2) and 63.2270(e).

(5) You must document procedures and acceptance criteria for operating and maintaining each COMS according to the requirements in § 63.8(d). At a minimum, the documentation must include a daily calibration drift assessment, a quarterly performance audit, and an annual zero alignment audit of each COMS.

(6) You must operate and maintain each COMS according to the requirements of § 63.8(e). You must identify periods the COMS is out of control including any periods that the COMS fails to pass a daily calibration drift assessment, a quarterly performance audit, or an annual zero alignment audit. Any 6-minute period for which the monitoring system is out of control and data are not available for a required calculation constitutes a deviation from the monitoring requirements.

(7) You must determine and record all the 6-minute averages (and 24-hour block averages as applicable) collected for periods during which the COMS is not out of control.

(1) The first compliance report must cover the period beginning on the compliance date that is specified for your affected source in § 63.2233 ending on June 30 or December 31, and lasting at least 6 months, but less than 12 months.

(d) The following combustion unit tune-up and bypass stack monitoring requirements must be conducted for all direct-fired dryers (including direct wood-fired PCWP dryers, direct natural gas-fired PCWP dryers, and direct-fired lumber kilns) by the dates specified in § 63.2233(e) and table 3 to this subpart. You must conduct an annual tune-up of each combustion unit used to directly-fire the PCWP dryer or lumber kiln following the procedures in § 63.2271(c) as specified in paragraphs (d)(1) through (3) of this section. You must monitor usage of combustion unit bypass stacks (defined in § 63.2292) following the procedures specified in § 63.2269(k) by the compliance date specified in § 63.2233(e).

(1) The initial tune-up must be completed by the compliance date specified in § 63.2233(e). After the initial tune-up, each annual tune-up is required to be completed no more than 13 months after the previous tune-up.

(2) If a combustion unit that direct-fires a PCWP dryer or lumber kiln is not operating on the required date for a tune-up, the tune-up must be conducted within 30 calendar days of startup of the combustion unit for the purpose of direct-firing a PCWP dryer or lumber kiln.

(3) For combustion units with tune-up requirements in this subpart, you may use documentation (required in § 63.7550(c)(1)) of the tune-up conducted according to §§ 63.7515(d) and 63.7540(a)(10), in place of the annual combustion unit tune-up requirements in this paragraph (d) and § 63.2271(c), provided the documentation required in § 63.7550(c)(1) is provided according to the schedule in paragraphs (d)(1) and (2) of this section.

(i) The initial inspection of kiln integrity must be completed by the compliance date specified in § 63.2233(e). After the initial inspection, each annual inspection is required to be completed no more than 13 months after the previous inspection.
