NR 460.02(24m)(a)(a) A modification to a federally enforceable test method that meets all of the following criteria: NR 460.02(24m)(a)3.3. Is site-specific, made to reflect or accommodate the operational characteristics, physical constraints or safety concerns of an affected source. NR 460.02(24m)(b)(b) Examples of minor changes to a test method include, but are not limited to: NR 460.02(24m)(b)1.1. Field adjustments in a test method’s sampling procedure, such as a modified sampling traverse or location to avoid interference from an obstruction in the stack, increasing the sampling time or volume, use of additional impingers for a high moisture situation, accepting particulate emission results for a test run that was conducted with a lower than specified temperature, substitution of a material in the sampling train that has been demonstrated to be more inert for the sample matrix. NR 460.02(24m)(b)2.2. Changes in recovery and analytical techniques such as a change in quality control or quality assurance requirements needed to adjust for analysis of a certain sample matrix. NR 460.02(24s)(24s) “Minor change to recordkeeping or reporting” means: NR 460.02(24s)(a)(a) A modification to federally required recordkeeping or reporting that meets all of the following criteria: NR 460.02(24s)(a)1.1. Does not decrease the stringency of the compliance and enforcement measures for the relevant standards. NR 460.02(24s)(b)(b) Examples of minor changes to recordkeeping or reporting include, but are not limited to: NR 460.02(24s)(b)2.2. Increased frequency of recordkeeping or reporting, or increased record retention periods. NR 460.02(24s)(b)3.3. Increased reliability in the form of recording monitoring data, such as electronic or automatic recording as opposed to manual recording of monitoring data. NR 460.02(24s)(b)5.5. Changes to recordkeeping for good cause shown for a fixed short duration, such as facility shutdown. NR 460.02(24s)(b)6.6. Changes to recordkeeping or reporting that is clearly redundant with equivalent recordkeeping or reporting requirements. NR 460.02(24s)(b)7.7. Decreases in the frequency of reporting for area sources to no less than once a year, for good cause shown, or for major sources to no less than twice a year, for good cause shown. NR 460.02(24w)(24w) “Monitoring” means the collection and use of measurement data or other information to control the operation of a process or pollution control device or to verify a work practice standard relative to assuring compliance with applicable requirements. Monitoring is composed of 4 elements: NR 460.02(24w)(a)(a) Indicators of performance—the parameters you measure or observe for demonstrating proper operation of the pollution control measures or compliance with the applicable emissions limitation or standard. Indicators of performance may include direct or predicted emissions measurements, including opacity, operational parametric values that correspond to process or control device and capture system efficiencies or emissions rates, and recorded findings of inspection of work practice activities, materials tracking, or design characteristics. Indicators may be expressed as a single maximum or minimum value; a function of process variables, for example, within a range of pressure drops; a particular operational or work practice status, for example, a damper position, completion of a waste recovery task, materials tracking; or an interdependency between 2 or among more than 2 variables. NR 460.02(24w)(b)(b) Measurement techniques—the means by which you gather and record information of or about the indicators of performance. The components of the measurement technique include the detector type, location and installation specifications, inspection procedures, and quality assurance and quality control measures. Examples of measurement techniques include continuous emission monitoring systems, continuous opacity monitoring systems, continuous parametric monitoring systems, and manual inspections that include making records of process conditions or work practices. NR 460.02(24w)(c)(c) Monitoring frequency—the number of times you obtain and record monitoring data over a specified time interval. Examples of monitoring frequencies include at least 4 points equally spaced for each hour for continuous emissions or parametric monitoring systems, at least every 10 seconds for continuous opacity monitoring systems, and at least once per operating day or week, month, etc. for work practice or design inspections. NR 460.02(24w)(d)(d) Averaging time—the period over which you average and use data to verify proper operation of the pollution control approach or compliance with the emissions limitation or standard. Examples of averaging time include a 3-hour average in units of the emissions limitation, a 30-day rolling average emissions value, a daily average of a control device operational parametric range, and an instantaneous alarm. NR 460.02(24y)(24y) “New affected source” means the collection of equipment, activities, or both within a single contiguous area and under common control that is included in a section 112 (c) source category or subcategory under section 112 of the Act (42 USC 7412) that is subject to a section 112 (d) or other relevant standard for new sources. This definition of new affected source, and the criteria to be utilized in implementing it, shall apply to each section 112 (d) standard for which the initial proposed rule is signed by the administrator after June 30, 2002. Each relevant standard will define the term new affected source, which will be the same as the affected source unless the administrator finds that a different collection is warranted based on consideration of factors including all of the following: NR 460.02(24y)(a)(a) Emission reduction impacts of controlling individual sources versus groups of sources.
