If Method 25A is used, the organic HAP used as the calibration gas must be the single organic HAP representing the largest percent by volume of the emissions. The use of Method 25A is acceptable if the response from the high-level calibration gas is at least 20 times the standard deviation of the response from the zero calibration gas when the instrument is zeroed on the most sensitive scale.(c) Each performance test shall consist of three separate runs; each run conducted for at least one hour under the conditions that exist when the hazardous waste management unit is operating at the highest load or capacity level reasonably expected to occur. For the purpose of determining total organic compound concentrations and mass flow rates, the average of results of all runs shall apply. The average shall be computed on a time- weighted basis.(d) Total organic mass flow rates shall be determined by the following equation: (1) For sources utilizing Method 18.

Q 2sd = Volumetric flow rate of gases entering or exiting control device, as determined by Method 2, dscm/h;
n = Number of organic compounds in the vent gas;
C i = Organic concentration in ppm, dry basis, of compound I in the vent gas, as determined by Method 18;
MW i = Molecular weight or organic compound i in the vent gas, kg/kg-mol;
0.0416 = Conversion factor for molar volume, kg-mol/m 3 (at 293 K and 760 mm Hg);

(2) For sources utilizing Method 25A. Eh = (Q)(C)(MW)(0.0416)(10-6)
where:
Eh = Total organic mass flow rate, kg/h;
Q = Volumetric flow rate of gases entering or exiting control device, as determined by Method 2, dscm/h;
C = Organic concentration in ppm, dry basis, as determined by Method 25A;
MW = Molecular weight of propane, 44;
0.0416 = conversion factor for molar volume, kg mol/m3 (at 293 K and 760 mm Hg);
10-6 = Conversion from ppm.
(e) The annual total organic emission rate shall be determined by the following equation: EA = (Eh) (H)
where:
EA = Total organic mass emission rate, kg/y;

H = Total annual hours of operations for the affected unit, h.
(f) Total organic emissions from all affected process vents at the facility shall be determined by summing the hourly total organic mass emission rates (Eh as determined in clause [i][d] of this paragraph) and by summing the annual total organic mass emission rates (EA, as determined in clause [i][ e] of this paragraph) for all affected process vents at the facility. (ii) The owner or operator of an affected facility shall record such process information as may be necessary to determine the conditions of the performance tests. Operations during periods of startup, shutdown, and malfunction shall not constitute representative conditions for the purpose of a performance test.(iii) The owner or operator of an affected facility shall provide, or cause to be provided, performance testing facilities as follows: (a) Sampling ports adequate for the test methods specified in subparagraph (i) of this paragraph.(b) Safe sampling platform(s).(c) Safe access to sampling platform(s).(d) Utilities for sampling and testing equipment.(iv) For the purpose of making compliance determinations, the time-weighted average of the results of the three runs shall apply. In the event that a sample is accidentally lost or conditions occur in which one of the three runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances beyond the owner's or operator's control, compliance may, upon the commissioner's approval, be determined using the average of the results of the two other runs. (4) To show that a process vent associated with a hazardous waste distillation, fractionation, thin-film evaporation, solvent extraction, or air or stream stripping operation is not subject to the requirements of this section, the owner or operator must make an initial determination that the time-weighted, annual average total organic concentration of the waste managed by the waste management unit is less than 10 ppmw using one of the following two methods: (i) Direct measurement of the organic concentration of the waste using the following procedures: (a) The owner or operator must take a minimum of four grab samples of waste for each waste stream managed in the affected unit under process conditions expected to cause the maximum waste organic concentration.(b) For waste generated onsite, the grab samples must be collected at a point before the waste is exposed to the atmosphere such as in an enclosed pipe or other closed system that is used to transfer the waste after generation to the first affected distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation. For waste generated offsite, the grab samples must be collected at the inlet to the first waste management unit that receives the waste provided the waste has been transferred to the facility in a closed system such as a tank truck and the waste is not diluted or mixed with other waste.(c) Each sample shall be analyzed and the total organic concentration of the sample shall be computed using Method 9060A of SW-846 (incorporated by reference under section 370.1[e] of this Title), or analyzed for its individual organic constituents.(d) The arithmetic mean of the results of the analyses of the four samples shall apply for each waste stream managed in the unit in determining the time-weighted, annual average total organic concentration of the waste. The time-weighted average is to be calculated using the annual quantity of each waste stream processed and the mean organic concentration of each waste stream managed in the unit.(ii) Using knowledge of the waste to determine that its total organic concentration is less than 10 ppmw. Documentation of the waste determination is required. Examples of documentation that shall be used to support a determination under this provision include production process information documenting that no organic compounds are used, information that the waste is generated by a process that is identical to a process at the same or another facility that has previously been demonstrated by direct measurement to generate a waste stream having a total organic content less than 10 ppmw, or prior speciation analysis results on the same waste stream where it can also be documented that no process changes have occurred since that analysis that could affect the waste total organic concentration.(5) The determination that distillation, fractionation, thin-film evaporation, solvent extraction, or air or stream stripping operations manage hazardous wastes with time-weighted, annual average total organic concentrations less than 10 ppmw shall be made as follows: (i) by the effective date that the facility becomes subject to the provisions of this section or by the date when the waste is first managed in a waste management unit, whichever is later; and(ii) for continuously generated waste, annually; or(iii) whenever there is a change in the waste being managed or a change in the process that generates or treats the waste.(6) When an owner or operator and the department do not agree on whether a distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation manages a hazardous waste with organic concentrations of at least 10 ppmw based on knowledge of the waste, the dispute may be resolved by using direct measurement as specified at subparagraph (4)(i) of this subdivision.(f)Recordkeeping requirements.(1)(i) Each owner or operator subject to the provisions of this section shall comply with the recordkeeping requirements of this subdivision.(ii) An owner or operator of more than one hazardous waste management unit subject to the provisions of this section may comply with the recordkeeping requirements for these hazardous waste management units in one recordkeeping system if the system identifies each record by each hazardous waste management unit.(2) Owners and operators must record the following information in the facility operating record: (i) For facilities that comply with the provisions of subparagraph (d)(1)(ii) of this section, an implementation schedule that includes dates by which the closed-vent system and control device will be installed and in operation. The schedule must also include a rationale of why the installation cannot be completed at an earlier date. The implementation schedule must be in the facility operating record by the effective date that the facility becomes subject to the provisions of this section.(ii) Up-to-date documentation of compliance with the process vent standards in subdivision (c) of this section, including: (a) Information and data identifying all affected process vents, annual throughput and operating hours of each affected unit, estimated emission rates for each affected vent and for the overall facility (i.e., the total emissions for all affected vents at the facility), and the approximate location within the facility of each affected unit (e.g., identify the hazardous waste management units on a facility plot plan).(b) Information and data supporting determinations of vent emissions and emission reductions achieved by add-on control devices based on engineering calculations or source tests. For the purpose of determining compliance, determinations of vent emissions and emission reductions must be made using operating parameter values (e.g., temperatures, flow rates, or vent stream organic compounds and concentrations) that represent the conditions that result in maximum organic emissions, such as when the waste management unit is operating at the highest load or capacity level reasonably expected to occur. If the owner or operator takes any action (e.g., managing a waste of different composition or increasing operating hours of affected waste management units) that would result in an increase in total organic emissions from affected process vents at the facility, then a new determination is required.(iii) Where an owner or operator chooses to use test data to determine the organic removal efficiency or total organic compound concentration achieved by the control device, a performance test plan. The test plan must include: (a) A description of how it is determined that the planned test is going to be conducted when the hazardous waste management unit is operating at the highest load or capacity level reasonably expected to occur. This shall include the estimated or design flow rate and organic content of each vent stream and define the acceptable operating ranges of key process and control device parameters during the test program.(b) A detailed engineering description of the closed-vent system and control device including: (1) manufacturer's name and model number of control device;(2) type of control device;(3) dimensions of the control device;(5) construction materials.(c) A detailed description of sampling and monitoring procedures, including sampling and monitoring locations in the system, the equipment to be used, sampling and monitoring frequency, and planned analytical procedures for sample analysis.(iv) Documentation of compliance with subdivision (d) of this section shall include the following information: (a) A list of all information references and sources used in preparing the documentation.(b) Records, including the dates, of each compliance test required by paragraph (d)(11) of this section.(c) If engineering calculations are used, a design analysis, specifications, drawings, schematics, and piping and instrumentation diagrams based on the appropriate sections of "APTI Course 415: Control of Gaseous Emissions" (incorporated by reference as specified in section 370.1[e] of this Title) or other engineering texts acceptable to the commissioner that present basic control device design information.
