Table 2 to Subpart TTTT of Part 63—Applicability of General Provisions to Subpart TTTT

As required in §63.5450, you must meet the appropriate NESHAP General Provision requirements in the following table:

General provisions citationSubject of citationBrief description of requirementApplies to
§63.1ApplicabilityInitial applicability determination; applicability after standard established; permit requirements; extensions, notifications.Yes
§63.2DefinitionsDefinitions for Part 63 standardsYesExcept as specifically provided in this subpart.
§63.3Units and abbreviationsUnits and abbreviations for Part 63 standardsYes
§63.4Prohibited activities and circumventionProhibited activities; compliance date; circumvention, severabilityYes
§63.5Construction/reconstructionApplicability; applications; approvalsYesExcept for paragraphs of §63.5 as listed below.
§63.5(d)(1)(ii)(H)Application for approvalType and quantity of HAP, operating parameters.NoAll sources emit HAP. Subpart TTTT does not require control from specific emission points.
§63.5(d)(1)(iii), (d)(2), (d)(3)(ii)Application for approvalNoThe requirements of the application for approval for new and reconstructed sources are described in §63.5320(b). General provision requirements for identification of HAP emission points or estimates of actual emissions are not required. Descriptions of control and methods, and the estimated and actual control efficiency of such do not apply. Requirements for describing control equipment and the estimated and actual control efficiency of such equipment apply only to control equipment to which the subpart TTTT requirements for quantifying solvent destroyed by an add-on control device would be applicable.
§63.6Applicability of general provisionsApplicability of general provisionsYesExcept for paragraphs of §63.6 as listed below.
§63.6(b)(1)-(3)Compliance dates, new and reconstructed sourcesNoSection §63.5283 specifies the compliance dates for new and reconstructed sources.
§63.6(e)(1)Operation and maintenance requirementsNoSee §63.5320(b) for general duty requirement.
§63.6(e)(3)Operation and maintenance requirementsStartup, shutdown, and malfunction plan requirementsNoSubpart TTTT does not have any startup, shutdown, and malfunction plan requirements.
§63.6(f)-(g)Compliance with nonopacity emission standards except during SSMComply with emission standards at all times except during SSMNoSubpart TTTT does not have nonopacity requirements.
§63.6(h)Opacity/visible emission (VE) standardsNoSubpart TTTT has no opacity or visual emission standards.
§63.6(i)Compliance extensionProcedures and criteria for responsible agency to grant compliance extensionYes
§63.6(j)Presidential compliance exemptionPresident may exempt source category from requirement to comply with subpartYes
§63.7Performance testing requirementsSchedule, conditions, notifications and proceduresYesExcept for paragraphs of §63.7 as listed below. Subpart TTTT requires performance testing only if the source applies additional control that destroys solvent. §63.5311 requires sources to follow the performance testing guidelines of the General Provisions if a control is added.
§63.7(a)(2) (i) and (iii)Performance testing requirementsApplicability and performance datesNo§63.5310(a) of subpart TTTT specifies the requirements of performance testing dates for new and existing sources.
§63.7(e)(1)Conduct of performance testsDefines representative conditions; provides an exemption from the standards for periods of startup, shutdown, and malfunction; requires that, upon request, the owner or operator shall make available to the Administrator such records as may be necessary to determine the conditions of performance testsNoSee §63.5380.
§63.8Monitoring requirementsApplicability, conduct of monitoring, operation and maintenance, quality control, performance evaluations, use of alternative monitoring method, reduction of monitoring dataNoSee §63.5360(a)(2) for monitoring requirements.
§63.9Notification requirementsApplicability and State delegationYesExcept for paragraphs of §63.9 as listed below.
§63.9(e)Notification of performance testNotify responsible agency 60 days aheadYesApplies only if performance testing is performed.
§63.9(f)Notification of VE/opacity observationsNotify responsible agency 30 days aheadNoSubpart TTTT has no opacity or visual emission standards.
§63.9(g)Additional notifications when using a continuous monitoring system (CMS)Notification of performance evaluation; notification using COMS data; notification that exceeded criterion for relative accuracyNoSee §63.5360(a)(2) for CMS requirements.
§63.9(h)Notification of compliance statusContentsNo§63.5320(d) specifies requirements for the notification of compliance status.
§63.10Recordkeeping/reportingSchedule for reporting, record storageYesExcept for paragraphs of §63.10 as listed below.

§63.10(c)RecordkeepingAdditional CMS recordkeepingNoSee §63.5360(a)(2) for CMS recordkeeping requirements.
§63.10(d)(2)ReportingReporting performance test resultsYesApplies only if performance testing is performed.
§63.10(d)(3)ReportingReporting opacity or VE observationsNoSubpart TTTT has no opacity or visible emission standards.
§63.10(d)(4)ReportingProgress reportsYesApplies if a condition of compliance extension.
§63.10(d)(5)ReportingStartup, shutdown, and malfunction reportingNoSee §63.5420(b) for reporting requirements if there is a deviation from the standard.
§63.10(e)ReportingAdditional CMS reportsNoSee §63.5360(a)(2) for monitoring requirements.
