Standards and Compliance Requirements §63.11495 What ar e the management practices and other requirements? (a) Management practices . If you have a CMPU subject to this subpart, you must comply with paragraphs (a)(1) through (5)

of this section. (1) Each process vessel must be equipped with a cover or

lid that m ust be closed at all times when it is in organic HAP

service or metal HAP service must be equipped with a cover or lid that must be in place at all times when the vessel contains

HAP , except for material operations that require access, such as

material add ition and removal, inspection, sampling , and cleaning

. (2) You must use any of the methods listed in paragraphs (a)(2)(i) through (iv) of this section to control total organic HAP emissions from transfer of liquids containing Table 1 organic HAP to tank tr ucks or railcars. You are not required to comply with this paragraph (a)(2) if you have notified thePage 9 of 77

Administrator in your initial notification that a material is reactive or resinous, and you will not be able to comply with any of the methods in paragraph s (a)(2)(i) through (iv) of this

section for the transfer of such material. (i) Use submerged loading or bottom loading. (ii) Route emissions to a fuel gas system or process in accordance with §63.982(d) of subpart SS. (iii) Vapor balance back to the stora ge tank or another storage tank connected by a common header. (iv) Vent through a closed

(i) Inspections must be con ducted at least quarterly. (ii) For these inspections, detection methods incorporating sight, sound, or smell are acceptable. The inspection must include direct and proximal (thorough) inspection of all areas of potential leak within the CMPU. Indications of a leak identified using such method constitute s a leak unless you

demonstrate that the indications of a leak are due to a

condition other than loss of HAP. Alternatively, Method 21 of 40Page 10 of 77

CFR part 60, appendix A

- 7, with a leak definition of 500 parts

per million by volume (ppmv), may be used for detection of leaks

or to determine if the indications of a leak are due to a

condition other than loss of HAP. If indications of a leak are determined not to be HAP in one quarterly monitoring period, you

must sti ll perform the inspection and demonstration in the next quarterly monitoring period. (iii) As an alternative to conducting inspections, as specified in paragraph (a)(3)(ii) of this section, you may use Method 21 of 40 CFR part 60, appendix A

- 7, with a leak definition of 500 ppmv to detect leaks. You may also use Method 21 with a leak definition of 500 ppmv to determine if indications of a leak identified during an inspection conducted in accordance with paragraph (a)(3)(ii) of this section are due

to a cond ition other than loss of HAP. The procedures in this paragraph (a)(3)(iii) may not be used as an alternative to the inspection required by paragraph (a)(3)(ii) of this section for process vessels that contain metal HAP as particulate. (iv) Inspections must be conducted while the subject CMPU is operating. (v) No inspection is required in a calendar quarter during which the subject CMPU does not operate for the entire calendar quarter and is not in organic HAP service or metal HAP service. If the CMPU operat es at all during a calendar quarter, anPage 11 of 77

inspection is required. (4) You must repair any leak within 15 calendar days after detection of the leak, or document the reason for any delay of repair. For the purposes of this paragraph (a)(4), a leak will

be cons idered ―repaired‖ if a condition specified in paragraph (a)(4)(i), (ii), or (iii) of this section is met. (i) The visual, audible, olfactory, or other indications of a leak to the atmosphere have been eliminated, or (ii) No bubbles are observed at potentia l leak sites during a leak check using soap solution, or (iii) The system will hold a test pressure. (5) You must keep records of the dates and results of each inspection event, the dates of equipment repairs, and, if applicable, the reasons for any delay in repair. (b) Small heat exchange systems . For each heat exchange system subject to this subpart with a cooling water flow rate less than 8,000 gallons per minute (gal/min) and not meeting one or more of the conditions in §63.104(a), you must comply with paragraphs (b)(1) through (3) of this section, or as an alternative, you may comply with any one of the requirements in Item 1.a or 1.b of Table 8 to this subpart. (1) You must develop and operate in accordance with a heat exchange system inspection plan. The plan must describe the inspections to be performed that will provide evidence ofPage 12 of 77

hydrocarbons in the cooling water. Among other things, inspections may include checks for visible floating hydrocarbon on the water, hydrocarbon odor, discolored water, an d/or chemical addition rates. You must conduct inspections at least once per quarter, even if the previous inspection determined

that the indications of a leak did not constitute a leak as defined by §63.104(b)(6). (2) You must perform repairs to eliminate the leak and any

indications of a leak or demonstrate that the HAP concentration in the cooling water does not constitute a leak, as defined by §63.104(b)(6), within 45 calendar days after indications of the leak are identified, or you must document the r eason for any delay of repair in your next semiannual compliance report. (3) You must keep records of the dates and results of each inspection, documentation of any demonstrations that indications of a leak do not constitute a leak, the dates of leak repai rs, and, if applicable, the reasons for any delay in repair. (c) Startup, shutdown, and malfunction

. Startup, shutdown, and malfunction (SSM) provisions in subparts that are referenced in paragraphs (a) and (b) of this section do not apply. (d) General dut y . At all times, you must operate and maintain any affected source, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practicesPage 13 of 77

for minimizing emissions. Determi nation of whether such operation and maintenance procedures are being used will be based on information available to the Administrator, which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source. §63.11496 What are the standards and compliance requirements for process vents? (a) Organic HAP Emissions from Batch Process Vents . You must comply with the requirements in paragraphs (a)(1) through (4) of this section for organic HAP emissions from your batch process vents for each CMPU using Table 1 organic HAP. If uncontrolled organic HAP emissions from all batch process vents from a CMPU subject to this subpart are equal to or greater tha n 10,000 pounds per year (lb/yr), you must also comply with the emission limits and other requirements in Table 2 to this subpart. (1) You must determine the sum of actual organic HAP emissions from all of your batch process vents within a CMPU subject to this subpart using process knowledge, engineering assessment, or test data. Emissions for a standard batch in a process may be used to represent actual emissions from each batch in that process. You must maintain records of the

calculations. Calculations o f annual emissions are not requiredPage 14 of 77

if you meet the emission standards for batch process vents in Table 2 to this subpart. (2) As an alternative to calculating actual emissions for each affected CMPU at your facility, you may elect to estimate

emissions fo r each CMPU based on the emissions for the worst

case CMPU. The worst

- case CMPU means the CMPU at the affected source with the highest organic HAP emissions per batch. The

worst

- case emissions per batch are used with the number of

batches run for other aff ected CMPU. Process knowledge, engineering assessment, or test data may be used to identify the

worst

- case process. You must keep records of the information and procedures used to identify the worst

- case process. (3) If your current estimate is that emissi ons from batch process vents from a CMPU are less than 10,000 pounds per year (lb/yr), then you must keep a record of the number of batches of each process operated per month. Also, you must reevaluate your total emissions from batch process vents prior to making any process changes that affect emission calculations in paragraphs (a)(1) and (2) of this section. If projected emissions increase to 10,000 lb/yr or more, you must be in compliance options for batch process vents in Table 2 to this subpart upon i nitiating operation under the new operating conditions. You must maintain records documenting the results of all updated emissions

calculations.Page 15 of 77

(4) As an alternative to determining the HAP emissions, you may elect to demonstrate that the amount of organic HAP used in the process is less than 10,000 lb/yr. You must keep monthly records of the organic HAP usage. (b) Organic HAP Emissions from Continuous Process Vents

. You must comply with the requirements in paragraphs (b)(1) through (3) of this section for organic HAP emissions from your continuous process vents for each CMPU subject to this subpart using Table 1 organic HAP. If the total resource

- effectiveness (TRE) index value for a continuous process vent is less than or equal to 1.0, you must also comply with the emission limits and other requirements in Table 3 to this subpart. (1) You must determine the TRE index value according to the procedures in §63.115(d), except as specified in paragraphs (b)(1)(i) through (iii) of this section. (i) You are not re quired to calculate the TRE index value if you control emissions in accordance with Table 3 to this subpart. (ii) Sections 63.115(d)(1)(i) and (ii) are not applicable for the purposes of this paragraph (b)(1)(ii). (iii) You may assume the TRE for a vent stream is > 1.0 if the amount of organic HAP emitted in the vent stream is less than 0.1 pound per hour. (2) If the current TRE index value is greater than 1, youPage 16 of 77

must recalculate the TRE index value before you make any process or operational change that a ffects parameters in the calculation. If the recalculated TRE is less than or equal to 1.0, then you must comply with one of the compliance options for continuous process vents in Table 3 to this subpart before operating under the new operating conditions. You must maintain

records of all TRE calculations. (3) If a recovery device as defined in §63.11502 is used to maintain the TRE index value at a level greater than 1.0 and less than or equal to 4.0, you must comply with §63.982(e) and the requirements spe cified therein. (c) Combined Streams . If you combine organic HAP emissions from batch process vents and continuous process vents, you must comply with the more stringent standard in Table 2 or Table 3 to this subpart that applies to any portion of the comb ined stream, or you must comply with Table 2 for the batch process vents and Table 3 for the continuous process vents. The TRE index value for continuous process vents and the annual emissions from batch process vents shall be determined for the individual streams before they are combined, and prior to any control, in order to determine the most stringent applicable requirements. (d) Combustion of Halogenated Streams . If you use a combustion device to comply with the emission limits for organic

HAP from a h alogenated batch process vent or a halogenatedPage 17 of 77

continuous process vent, you must use a halogen reduction device to meet the emission limit in either paragraph (d)(1) or (d)(2) of this section and in accordance with §63.994 and the requirements referenced t herein. (1) Reduce overall emissions of hydrogen halide and halogen HAP after the combustion device by greater than or equal to 95 percent, to less than or equal to 0.45 kilograms per hour (kg/hr), or to a concentration less than or equal to 20 parts

per m illion by volume (ppmv). (2) Reduce the halogen atom mass emission rate before the combustion device to less than or equal to 0.45 kg/hr or to a concentration less than or equal to 20 ppmv. (e) Alternative Standard for Organic HAP . Exceptions to the requir ements for the alternative standard requirements specified in Tables 2 and 3 to this subpart and §63.2505 are specified in paragraphs (e)(1) through (5) of this section. (1) When §63.2505 of subpart FFFF refers to Tables 1 and 2 to subpart FFFF and §§63.24 55 and 63.2460, it means Tables 2 and 3 to this subpart and §63.11496(a) and (b). (2) Sections 63.2505(a)(2) and (b)(9) do not apply. (3) When §63.2505(b) references §63.2445 it means §63.11494(f) through (h). (4) The requirements for hydrogen halide and h alogen HAP apply only to hydrogen halide and halogen HAP generated in aPage 18 of 77

combustion device that is used to comply with the alternative

standard. (5) When §63.1258(b)(5)(ii)(B)( 2 ) refers to a ―notification of process change‖ report, it means the semi

- annual compliance report required by §63.11501(d) for the purposes of this subpart. (f) Emissions from Metal HAP Process Vents . You must comply with the requirements in paragraphs (f)(1) and (2) of this section for metal HAP emissions from each CMPU using Table 1

metal HAP. If the collective uncontrolled metal HAP emissions from all metal HAP process vents from a CMPU are equal to or greater than 400 lb/yr, then you must also comply with the emission limits and other requirements in Table 4 to this subpart and in paragraph (f)(3), (4), or (5) of this section. (1) You must determine the sum of metal HAP emissions from all metal HAP process vents within a CMPU subject to this subpart, except you are not required to determine the annual emissions if you control the me tal HAP process vents within a CMPU in accordance with Table 4 to this subpart or if you determine your total metal HAP usage in the process unit is less than 400 lb/yr. To determine the mass emission rate you may use process knowledge, engineering assessm ent, or test data. You must keep records of the emissions calculations. (2) If your current estimate is that total uncontrolledPage 19 of 77

metal HAP emissions from a CMPU subject to this subpart are less than 400 lb/yr, then you must keep records of either the number of batches operated per month (batch vents) or the process operating hours (continuous vents). Also, you must reevaluate your total emissions before you make any process or operational change that affects emissions of metal HAP. If projected

emissions inc rease to 400 lb/yr or more, then you must be in compliance with one of the options for metal HAP process vents in Table 4 to this subpart upon initiating operation under the new operating conditions. You must keep records of all

recalculated emissions dete rminations. (3) If you have an existing source subject to the HAP metals emission limits specified in Table 4 to this subpart, you must comply with the initial compliance and monitoring requirements in paragraphs (f)(3)(i) through (iii) of this

section. Yo u must keep records of monitoring results to demonstrate continuous compliance. (i) You must prepare a monitoring plan containing the information in paragraphs (f)(3)(i)(A) through (E) of this section. The plan must be maintained on

- site and be available o n request. You must operate and maintain the control device according to a site

- specific monitoring plan at all times. (A) A description of the device; (B) Results of a performance test or engineering assessmentPage 20 of 77

conducted in accordance with paragraph (f)(3 )(ii) of this section verifying the performance of the device for reducing HAP metals or particulate matter (PM) to the levels required by this subpart; (C) Operation and maintenance plan for the control device (including a preventative maintenance schedul e consistent with the manufacturer's instructions for routine and long

- term maintenance) and continuous monitoring system. (D) A list of operating parameters that will be monitored to maintain continuous compliance with the applicable emissions limits; and (E) Operating parameter limits based on either monitoring data collected during the performance test or established in the engineering assessment. (ii) You must conduct a performance test or an engineering assessment for each CMPU subject to a HAP metals emissions limit in Table 4 to this subpart and report the results in your Notification of Compliance Status (NOCS) report. Each performance test or engineering assessment must be conducted under representative operating conditions, and sampling for each

pe rformance test must be conducted at both the inlet and outlet of the control device. Upon request, you shall make available to the Administrator such records as may be necessary to determine the conditions of performance tests. If you own or operate anPage 21 of 77

exi sting affected source, you are not required to conduct a performance test if a prior performance test was conducted within the 5 years prior to the effective date using the same methods specified in paragraph (f)(3)(iii) of this section , and , either no pro cess changes have been made since the test, or , if you can demonstrate that the results of the performance test, with or without adjustments, reliably demonstrate compliance despite process changes. For each performance test, sampling

must be conducted at both the inlet and outlet of the control device, and the test must be conducted under representative process operating conditions. (iii) If you elect to conduct a performance test, it must be conducted according to requirements in §63.11410(j)(1). As an

al ternative to conducting a performance test using Method 5 or 5D to determine the concentration of PM, you may use Method 29 in 40 CFR part 60, appendix A

- 8 to determine the concentration of HAP metals. You have demonstrated initial compliance if the

overal l reduction of either HAP metals or total PM is equal to or greater than 95 percent. (4) If you have a new source using a baghouse as a control device, you must install, operate, and maintain a bag leak detection system on all baghouses used to comply with the HAP metals emissions limit in Table 4 to this subpart. You must comply with the testing, monitoring, and recordkeepingPage 22 of 77

requirements in §63.11410(g), (i), and (j)(1), except you are not required to submit the monitoring plan required by §63.11410(g)(2) for approval. (5) If you have a new source using a control device other than a baghouse to comply with the HAP metals emission limits in Table 4 to this subpart, you must comply with the initial compliance and monitoring requirements in paragraphs (f)(3)( i) through (iii) of this section.

make these repairs; and (iii) The frequency, amount, and duration of the excess emissions (including any bypass) were minimized to the maximum extent practicable during periods of such emissions; and (iv) If the excess emissions resulted from a bypass of control equi pment or a process, then the bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; and (v) All possible steps were taken to minimize the impact of the excess emissions on ambient air quality, the environment and

human health; and (vi) All emissions monitoring and control systems were kept in operation, if at all possible, consistent with safety and good air pollution control practices; and (vii) All of the actions in response to the excess emissions were documented by properly signed, contemporaneous operating logs; and (viii) At all times, the affected source was operated in a manner consistent with good practices for minimizing emissions;

and (ix) A written root cause analysis has been prepared, the purpose of which i s to determine, correct, and eliminate the primary causes of the malfunction and the excess emissions resulting from the malfunction event at issue. The analysis mustPage 42 of 77

also specify, using best monitoring methods and engineering judgment, the amount of exces s emissions that were the result of

the malfunction. (2) Notification
