PART 63—NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES

Subpart UUU—National Emission Standards fo r Hazardous Air Pollu tants for Petroleum Refineries: Catalytic Cracking Units, Cata lytic Reforming Units, and Sulfur Recovery Units

What This Subpart Covers

§63.1560 What is the purpose of this subpart?

This subpart establishes national emission sta ndards for hazardous air pollutants (HAP) emitted from petroleum refineries. This subpart also esta blishes requirements to demonstrate initial and continuous compliance with the emission li mitations and work practice standards.

§63.1561 Am I subject to this subpart?

(a) You are subject to this subpart if you own or operate a petroleum refinery that is located at a major source of HAP emissions.

(1) A petroleum refinery is an establishment e ngaged primarily in petroleum refining as defined in the Standard Industrial Classification (S IC) code 2911 and the North American Industry Classification (NAIC) code 32411, and used mainly for:

(i) Producing transportation fuels (such as gasolin e, diesel fuels, and jet fuels), heating fuels (such as kerosene, fuel gas distilla te, and fuel oils), or lubricants;

(ii) Separating petroleum; or

(iii) Separating, cracking, reacting, or reforming an intermediate petroleum stream, or recovering a by-product(s) from the intermediate pe troleum stream (e.g., sulfur recovery).

(2) A major source of HAP is a plant site that emits or has the potential to emit any single HAP at a rate of 9.07 megagrams (10 tons) or more pe r year or any combination of HAP at a rate of 22.68 megagrams (25 tons) or more per year.2 (b) [Reserved]

§63.1562 What parts of my plant are covered by this subpart?

(a) This subpart applies to each new, reconstruc ted, or existing affected source at a petroleum refinery.

(b) The affected sources are:

(1) The process vent or group of process vents on fluidized catalytic cracking units that are associated with regeneration of the catalyst used in the unit ( i.e. , the catalyst regeneration flue gas vent).

(2) The process vent or group of process vents on catalytic reforming units (including but not limited to semi-regenerative, cyclic, or conti nuous processes) that are associated with regeneration of the catalyst used in the unit. Th is affected source include s vents that are used during the unit depressurization, purging, c oke burn, and catalyst rejuvenation.

(3) The process vent or group of process vents on Claus or other types of sulfur recovery plant units or the tail gas treatment units serving sulfur recovery plants

, that are associated with sulfur
recovery.
(4) Each bypass line serving a new, existing, or reconstructed catalytic cracking unit, catalytic reforming unit, or sulfur recovery unit. This m eans each vent system that contains a bypass line (e.g., ductwork) that could divert an affected vent stream away from a control device used to comply with the requirements of this subpart.

(c) An affected source is a new affected sour ce if you commence construction of the affected source after September 11, 1998, and you meet the applicability criteria in §63.1561 at the time you commenced construction.

(d) Any affected source is reconstruc ted if you meet the criteria in §63.2.

(e) An affected source is existing if it is not new or reconstructed.

(f) This subpart does not apply to:

(1) A thermal catalytic cracking unit.

(2) A sulfur recovery unit that does not recover elemental sulfur or where the modified reaction is carried out in a water solution which contains a metal ion capable of oxidizing the sulfide ion to sulfur (e.g., the LO-CAT II process).

(3) A redundant sulfur recovery un it not located at a pe troleum refinery and used by the refinery only for emergency or maintenance backup.3 (4) Equipment associated with bypass lines such as low leg drains, hi gh point bleed, analyzer vents, open-ended valves or lines, or pressure relief valves needed for safety reasons.

(5) Gaseous streams routed to a fuel gas system , provided that on and after [THE DATE 3 YEARS AFTER THE DATE OF PUBLI CATION OF THE FINAL RULE AMENDMENTS IN THE FEDERAL REGISTER], an y flares receiving gas from the fuel gas system are in compliance with §63.670

The SSMP must include elements designed to minimize the frequency of such periods (i.e., root cause analysis). The Administrator will determine whether deviations that occur during a period of startup, shutdown, or malfunction are violations, according to the provisions in §63.6(e).24 §63.1571 How and when do I conduct a performa nce test or other initial compliance demonstration?

(a) When must I conduct a performance test? You must conduct performance tests and report the results by no later than 150 da ys after the compliance date sp ecified for your source in §63.1563 and according to the provisions in §63.7(a)(2 ).

Appendix A to Subpart UUU of Part 63—Deter mination of Metal Concentration on Catalyst Particles (Instrumental Analyzer Procedure)

1.0 Scope and Application.

1.1 Analytes. The analytes for which this method is applicable include any elements with an atomic number between 11 (sodium) and 92 (urani um), inclusive. Specific analytes for which this method was developed include:168 Analyte CAS No. Minimum detectable limit Nickel compounds 7440–02–0 <2 % of span. Total chlorides 16887–00–6 <2 % of span.

1.2 Applicability. This method is applicable to the determination of an alyte concentrations on catalyst particles. This method is applicable for catalyst particles obtained from the fluid catalytic cracking unit (FCCU) regenerator ( i.e. , equilibrium catalyst), from air pollution control systems operated for the FCCU catalyst regenerator vent (FCCU fines), from cat alytic reforming units (CRU), and other processes as specified with in an applicable regulation. This method is applicable only when specified within the regulation.

1.3 Data Quality Objectives. Adherence to the requirements of this method will enhance the quality of the data obtained from the analytical method.

2.0 Summary of Method.

2.1 A representative sample of catalyst particles is collected, prepared, and analyzed for analyte concentration using either energy or wavelength disp ersive X-ray fl o u o rescent (XRF) spectrometry instrumental analyzers. In both types of XRF spectrometers, the instrument irradiates the sample with high energy (primary) x-rays and the elements in the sample absorb the x-rays and then re-emit sec ondary (fluorescent) x-rays of ch aracteristic wavelengths for each element present. In energy dispersive XRF spectrometers, all secondary x-rays (of all wavelengths) enter the detector at once. The detect or registers an electric current having a height proportional to the photon energy, an d these pulses are then sepa rated electronically, using a pulse analyzer. In wavelength dispersive XRF sp ectrometers, the secondary x-rays are dispersed spatially by crystal diffraction on th e basis of wavelength. The crystal and detector are made to synchronously rotate and the detector then receive s only one wavelength at a time. The intensity of the x-rays emitted by each element is proporti onal to its concentration, after correcting for matrix effects. For nickel compounds and tota l chlorides, the XRF instrument response is expected to be linear to analyt e concentration. Performance specifi cations and test procedures are provided to ensure reliable data.

4.0 Interferences.

4.1 Spectral interferences with analyte line intensity determin ation are accounted for within the method program. No action is required by the XR F operator once these interferences have been addressed within the method.

4.2 The X-ray production efficiency is affected by particle size for the very lightest elements. However, particulate matter (PM) 2.5 particle size effects are substantiall y < 1 percent for most elements. The calibration standards should be prepared with material of similar particle size or be processed (ground) to produce ma terial of similar particle size as the catalyst samples to be analyzed. No additional correction for particle size is performed. Altern atively, the sample can be fused in order to eliminate a ny potential particle size effects.

5.0 Safety.

5.1 Disclaimer. This method may i nvolve hazardous materials, operations, and equipment. This test method may not address all of the safety pr oblems associated with its use. It is the responsibility of the user of this test method to establish appr opriate safety and health practices and determine the applicability of regulatory limitations prior to performing this test method.170 5.2 X-ray Exposure. The XRF uses X-rays; XRF operators should follow instrument manufacturer's guidelines to protect from accidental exposure to X-rays when the instrument is in operation.

5.3 Beryllium Window. In most XRF units, a beryllium (Be) window is present to separate the sample chamber from the X-ray tube and detector . The window is very fragile and brittle. Do not allow sample or debris to fall onto the window , and avoid using compressed air to clean the window because it will cause the window to ruptur e. If the window should rupture, note that Be metal is poisonous. Use extreme caution when collec ting pieces of Be and consult the instrument manufacturer for advice on cleanup of the broken window and replacement.

7.0 Reagents and Standards.

7.1 Calibration Standards. The calibration standards for the analyzer must be prepared catalyst samples or other material of similar particle size and matrix as the catalyst samples to be tested that have known concentrations of the analytes of interest. Preparation (grinding/milling/fusion) of the calibration standards should follow the sa me processes used to prepare the catalyst samples to be tested. The calibration standards va lues must be established as the average of a minimum of three analyses using an approved EP A or ASTM method with instrument analyzer calibrations traceable to the U.S. National In stitute of Standards and Technology (NIST), if available. The maximum percent deviation of th e triplicate calibration st andard analyses should agree within 10 percent of the average value for the triplicate analysis (see Figure 1). If the calibration analyses do not meet this criteria, th e calibration standards mu st be re-analyzed. If unacceptable variability persists, new calibration standards must be prepared. Approved methods for the calibration standard analyses include , but are not limited to, EPA Methods 6010B, 6020,171 7520, or 7521 of SW–846. 1 Use a minimum of four calibration standards as specified below (see Figure 1):

7.1.1 High-Range Calibration Standard. Concentrati on equivalent to 80 to 100 percent of the span. The concentration of the high-range cal ibration standard should exceed the maximum concentration anticipated in the catalyst samples.

7.1.2 Mid-Range Calibration Standard. Concentration equivalent to 40 to 60 percent of the span.

7.1.3 Low-Range Calibration Standard. Concentration eq uivalent to 1 to 20 percent of the span. The concentration of the low-range calibration standa rd should be selected so that it is less than either one-fo u rth of the applicable concentration limit or of the lowest con centration anticipated in the catalyst samples.

7.1.4 Zero Calibration Standard. Concentration of less than 0.25 percent of the span.

7.2 Accuracy Assessment Standard. Prepare an a ccuracy assessment standard and determine the ideal value for the accuracy assessment standard following the same procedures used to prepare and analyze the calibration standards as de scribed in section 7.1. The maximum percent deviation of the triplicate accura cy assessment standard analyses should agree within 10 percent of the average value for the tripli cate analysis (see Figure 1). The concentration equivalent of the accuracy assessment standard must be between 20 and 80 percent of the span.

7.3 Energy Calibration Standard. Generally, the ener gy calibration standard will be provided by the XRF instrument manufacturer for energy di spersive spectrometers. Energy calibration is performed using the manufacturer's recomm ended calibration standard and involves measurement of a specific energy line (based on the metal in the energy calibration standard). This is generally an automated procedure used to assure the accuracy of the energy scale. This calibration standard may not be applicable to all models of XRF spect rometers (particularly wavelength dispersive XRF spectrometers).

8.0 Sample Collection, Preservation, Transport, and Storage. [Reserved]

9.0 Quality Control.

9.1 Energy Calibration. For energy dispersive sp ectrometers, conduct the energy calibration by analyzing the energy calibrati on standard provided by the manuf acturer. The energy calibration involves measurement of a specific energy line (based on the metal in the energy calibration standard) and then determination of the differe nce between the measured peak energy value and the ideal value. This analysis, if applicable, should be performed daily prior to any sample analyses to check the instrument's energy scale. This is generally an automated procedure and assures the accuracy of the energy scale. If th e energy scale calibration pr ocess is not automated, follow the manufacturer's procedures to manua lly adjust the instrument, as necessary.

9.2 Zero Drift Test. Conduct the zer o drift test by analyzing the analyte concentration output by the measurement system with th e initial calibration value for the zero calibration standard (see Figure 2). This analysis should be perfor med with each set of samples analyzed.172 9.3 Calibration Drift Test. Conduc t the calibration dr ift test by analyzing the analyte concentration output by the measurement system with the initial calibration value for the midrange calibration standard (see Figure 2). This an alysis should be perfor med with each set of samples analyzed.

9.4 Analyzer Accuracy Test. Conduct the analyz er accuracy test by analyzing the accuracy assessment standard and comparing the value out put by the measurement system with the ideal value for the accuracy assessment standard (see Figure 2). This analysis should be performed with each set of samples analyzed.

10.0 Calibration and Standardization.

10.1 Perform the initial calibration and set-up following the instrument manufacturer's instructions. These procedures s hould include, at a minimum, the major steps listed in sections 10.2 and 10.3. Subsequent calibrations are to be performed when either a quality assurance/quality control (QA/QC) limit listed in section 13 is exceeded or when there is a change in the excitation conditions, such as a change in the tube, de tector, X-ray filters, or signal processor. Calibrations are typically valid for 6 months to 1 year.

10.2 Instrument Calibration. Calibration is perfor med initially with calibration standards of similar matrix and binders, if used, as the samples to be analyzed (see Figure 1).

10.3 Reference Peak Spectra. Acquisition of referen ce spectra is required only during the initial calibration. As long as no processi ng methods have changed, these peak shape references remain valid. This procedure consists of placing the stan dards in the instrument and acquiring individual elemental spectra that are stored in the method file with each of the anal ytical conditions. These reference spectra are used in the standa rd deconvolution of the unknown spectra.

11.0 Analytical Procedure.

11.1 Sample Preparation. Prepare catalyst samples using the same procedure used to prepare the calibration standards. Measure and record the we ight of sample used. Measure and record the amount of binder, if any, used. Pellets or films mu st be of sufficient size to cover the analyzer sample window.

11.2 Sample Analyses. Place the prepared cataly st samples into the analyzer. Follow the manufacturer's instructions for analyzing the samples.

11.3 Record and Store Data. Use a digital recorder or personal computer to record and store results for each sample. Record any mechanical or software problems encountered during the analysis.

12.0 Data Analysis and Calculations.

Carry out the following calculations, retaining at least one extra si gnificant figure beyond that of the acquired data. Round off fi gures after final calculation.173 12.1 Drift.

Where:

Accuracy Value = Percent difference of instrument response to the ideal response for the accuracy assessment standard;

CurrentAnalyzerCal.Response = Instrument re sponse for current QC sample analyses;

IdealCal.Response = Ideal instrument response for the accuracy assessment standard.

13.0 Method Performance.

13.1 Analytical Range. The analytical range is determined by the instrument design. For this method, a portion of the analytical range is se lected by choosing the span of the monitoring system. The span of the monitoring system must be selected such that it encompasses the range of concentrations anticipated to occur in the catalyst sample. If applicable, the span must be selected such that the analyte concentration equi valent to the emission standard is not less than 30 percent of the span. If the measured analyte concentration exceeds th e concentration of the high-range calibration standard, the sample analys is is considered invalid. Additionally, if the measured analyte concentration is less than the concentration of th e low-range calibration standard but above the detectable limit, the sa mple analysis results must be flagged with a footnote stating, in effect, that the analyte was detected but that the reported concentration is below the lower quantitation limit.

13.2 Minimum Detectable Limit. The minimum dete ctable limit depends on the signal-to-noise ratio of the measurement system. For a well-d esigned system, the minimum detectable limit should be less than 2 percent of the span.174 13.3 Zero Drift. Less than ±2 percent of the span.

13.4 Calibration Drift. Less than ±5 percent of the span.

13.5 Analyzer Accuracy Error. Less than ±10 percent.
