(a) You must demonstrate continuous compliance with the compliance options, operating requirements, and work practice requirements in §§ 63.2240 and 63.2241 that apply to you according to the methods specified in Tables 7 and 8 to this subpart.

(b) You must report each instance in which you did not meet each compliance option, operating requirement, and work practice requirement in Tables 7 and 8 to this subpart that applies to you. This includes periods of startup, shutdown, and malfunction and periods of control device maintenance specified in paragraphs (b)(1) through (4) of this section. These instances are deviations from the compliance options, operating requirements, and work practice requirements in this subpart. These deviations must be reported according to the requirements in § 63.2281.

(1)-(2) [Reserved]

(3) Deviations that occur during periods of control device maintenance covered by any approved routine control device maintenance exemption are not violations if you demonstrate to the EPA Administrator's satisfaction that you were operating in accordance with the approved routine control device maintenance exemption.

(4) Instances of safety-related shutdown, pressurized refiner startup and shutdown, and startup and shutdown of direct-fired softwood veneer dryer gas-fired burners subject to the work practice requirements in table 3 to this subpart (rows 6 through 8) must be reported as required in § 63.2281(c)(4). Instances when the work practice requirements in table 3 to this subpart (rows 6 through 8) are used are not considered to be deviations from (or violations of) the otherwise applicable compliance options, operating requirements and work practice requirements (in rows 1 through 5 of table 3 to this subpart) as long as you do not exceed the minimum amount of time necessary for these events and continuously monitor process unit bypass stack usage during the events as required in § 63.2240(e) and table 2 to this subpart.

(c) For direct-fired PCWP dryers (including direct wood-fired PCWP dryers and direct natural gas-fired PCWP dryers) and direct-fired lumber kilns, demonstrate compliance with the annual tune-up requirement in § 63.2241(d) and table 3 to this subpart as specified in paragraphs (c)(1) through (8) of this section.

(1) You must conduct the tune-up while burning the type of fuel (or fuels in case of units that routinely burn a mixture) that provided the majority of the heat input to PCWP dryer or lumber kiln over the 12 months prior to the tune-up.

(2) Inspect the burner and (if applicable) grates. Clean, repair, or replace any components of the burner and grates as necessary. This work must be initiated within 30 days after the inspection and completed within 180 days following the inspection identifying the need for the corrective action. If the corrective action cannot be completed within 180 days, a written request for an extension may be submitted to the delegated authority, who may grant an extension if they determine additional time is necessary.

(3) For direct-fired PCWP dryers with burners in the dryer or separate combustion unit(s), inspect the flame pattern (as applicable) and adjust the burner as necessary to optimize the flame pattern. The adjustment should be consistent with the manufacturer's specifications, if available.

(4) For each direct-fired PCWP dryer with a burner in the dryer, cycle the burner through its firing range to ensure the burner functions satisfactorily throughout the operating range.

(5) Inspect the combustion air system and system that controls the air-to-fuel ratio to make sure it is functioning properly (according to the manufacturer's guidelines, if available).

(6) Inspect the fuel delivery system and, if applicable, the ash removal system to make sure each system is functioning properly (according to the manufacturer's guidelines, if available).

(7) Record the results of each inspection and corrective action taken, as required in § 63.2282.

(8) The required inspections and any necessary maintenance must be performed annually (no more than 13 months after previous inspection). If inspections are performed more frequently than annually, required equipment maintenance and replacement may be delayed until the next scheduled shutdown of the combustion unit firing a PCWP dryer or lumber kiln.
