§ 63.1292 Definitions.

All terms used in this subpart shallhave the meaning given them in theAct, in subpart A of this part, and inthis section. If a term is defined in sub-part A and in this section, it shall havethe meaning given in this section forpurposes of this subpart.

Auxiliary blowing agent, or ABA,means a low-boiling point liquid addedto assist foaming by generating gas be-yond that resulting from theisocyanate-water reaction.

Breakthrough means that point in theadsorption step when the mass transferzone (i.e., the section of the carbon bedwhere the HAP is removed from thecarrier gas stream) first reaches thecarbon bed outlet as the mass transferzone moves down the bed in the direc-tion of flow. The breakthrough point ischaracterized by the beginning of asharp increase in the outlet HAP or or-ganic compound concentration.

Calibrate means to verify the accu-racy of a measurement device against aknown standard. For the purpose ofthis subpart, there are two levels ofcalibration. The initial calibration in-cludes the verification of the accuracyof the device over the entire operatingrange of the device. Subsequent cali-brations can be conducted for a pointor several points in a limited range ofoperation that represents the mostcommon operation of the device.

Canned motor pump means a pumpwith interconnected cavity housings,motor rotors, and pump casing. In acanned motor pump, the motor bear-ings run in the process liquid and allseals are eliminated.

Carbon adsorption system means a sys-tem consisting of a tank or containerthat contains a specific quantity of ac-tivated carbon. For the purposes of thissubaprt, a carbon adsorption system isused as a control device for storagevessels. Typically, the spent carbon beddoes not undergo regeneration, but isreplaced.

Flexible polyurethane foam means aflexible cellular polymer containingurea and carbamate linkages in thechain backbone produced by reacting adiisocyanate, polyol, and water. Flexi-ble polyurethane foams are open-celled, permit the passage of airthrough the foam, and possess thestrength and flexibility to allow re-peated distortion or compression understress with essentially complete recov-ery upon removal of the stress.

Flexible polyurethane foam processmeans the equipment used to produce aflexible polyurethane foam product.For the purpose of this subpart, theflexible polyurethane foam process in-cludes raw material storage; produc-tion equipment and associated piping,ductwork, etc.; and curing and storageareas.

Grade of foam means foam with a dis-tinct combination of indentation forcedeflection (IFD) and density values.

HAP ABA means methylene chloride,or any other HAP compound used as anauxiliary blowing agent.

§ 63.1297 Standards for slabstock flexi-ble polyurethane foam production—HAP ABA emissions from the pro-duction line.

Compliance shall be deter-mined on a rolling annual basis as de-scribed in paragraph (a)(1) of this sec-tion. As an alternative, the owner oroperator can determine compliance ona monthly basis, as described in para-graph (a)(2) of this section.

(1) Rolling annual compliance. In de-termining compliance on a rolling an-nual basis, actual HAP ABA emissionsshall be compared to allowable HAPABA emissions for each consecutive 12-month period. The allowable HAP ABAemission level shall be calculated basedon the production for the 12-month pe-riod, resulting in a potentially dif-ferent allowable level for each 12-month period. Compliance shall be de-termined each month for the previous12-month period. The compliance re-quirements are provided in paragraph(b) of this section.

(2) Monthly compliance alternative. Asan alternative to determining compli-ance on a rolling annual basis, anowner or operator can determine com-pliance by comparing actual HAP ABAemissions to allowable HAP ABA emis-sions for each month. The allowableHAP ABA emission level shall be cal-

culated based on the production for themonth, resulting in a potentially dif-ferent allowable level each month. Therequirements for this monthly compli-ance alternative are provided in para-graph (c) of this section.

(3) Each owner or operator electingto change between the compliancemethods described under paragraphs(a)(1) and (a)(2) of this section shall no-tify the Administrator no later than180 calendar days prior to the change.

(b) Rolling annual compliance. At eachslabstock foam production source com-plying with the rolling annual compli-ance provisions described in paragraph(a)(1) of this section, actual HAP ABAemissions shall not exceed the allow-able HAP ABA emission level for a con-secutive 12-month period. The actualHAP ABA emission level for a consecu-tive 12-month period shall be deter-mined using the procedures in para-graph (b)(1) of this section, and the al-lowable HAP ABA emission level forthe corresponding 12-month periodshall be calculated in accordance withparagraph (b)(2) of this section.

(1) The actual HAP ABA emissionsfor a 12-month period shall be cal-culated as the sum of actual monthlyHAP ABA emissions for each of the in-dividual 12 months in the period. Ac-tual monthly HAP ABA emissions shallbe equal to the amount of HAP ABAadded to the slabstock foam productionline at the mixhead, determined in ac-cordance with § 63.1303(b), unless a re-covery device is used. Slabstock foamproduction sources using recovery de-vices to reduce HAP ABA emissionsshall determine actual monthly HAPABA emissions using the procedures inparagraph (e) of this section.

(2) The allowable HAP ABA emis-sions for a consecutive 12-month periodshall be calculated as the sum of allow-able monthly HAP ABA emissions foreach of the individual 12 months in theperiod. Allowable HAP ABA emissionsfor each individual month shall be cal-culated using Equation 2.

a concentration of approximately, 1,000ppm for all transfer pumps; and 500ppm for all other equipment, except asprovided in paragraph (a)(4)(iii) of thissection.

(iii) The instrument may be cali-brated at a higher methane concentra-tion (up to 2,000 ppm) than the leakdefinition concentration for a specificpiece of equipment for monitoring thatpiece of equipment.
