FINAL

Secretary's Order No.: 2016-A-0047

Date of Issuance: November 21, 2016

Effective Date of the Amendment: January 11, 2017

1124 Control of Volatile Organic Compound Emissions

Under the authority vested in the Secretary of the Department of Natural Resources and Environmental Control ("Department" or "DNREC") pursuant to 7 Del.C. §§6006, 6010, the following findings of fact based on the record, reasons and conclusions are entered as an Order of the Secretary in the above-referenced regulatory proceeding.

Background, Procedural History and Findings of Fact

This Order relates to the proposed Revisions to the Delaware State Implementation Plan ("SIP") to address the Start-up, Shutdown, and Malfunction ("SSM") SIP Call of the United States Environmental Protection Agency ("USEPA", "EPA") of June 12, 2015 (see 80 FR 33840). As a result of a petition to EPA by the Sierra Club, the EPA has identified thirty-six (36) states with inadequate SIPs as they relate to SSM activities. EPA has specifically identified seven (7) existing Delaware rules in the SIP Call. The seven Delaware regulations cited by EPA were 7 DE Admin. Code 1104, 1105, 1108, 1109, 1114, 1124, and 1142. As a result, Delaware is proposing revisions to four of these regulations, as follows, to wit: 7 DE Admin. Code 1104, 1105, 1124 and 1142.

While the three remaining regulations noted above (7 DE Admin. Code 1108, 1109, and 1114) are also part of the aforementioned SIP Call, the Department is not proposing revisions to the same at this time. 7 DE Admin. Code 1109 and 1114 are at this present time being removed from the SIP. With regard to 7 DE Admin. Code 1108, the Department had already removed the offending SSM language when that regulation was last revised in 2013. As such, the Department is formally addressing all three of these remaining regulations, but not proposing any amendments to the same as part of this present action.

It should be noted that the Department received comments prior to the public hearing of October 25, 2016 from both the Sierra Club and the EPA on the aforementioned proposed regulatory Amendments and SIP revisions. As noted within the Department's Technical Response Memorandum ("TRM") prepared in this matter by the Division of Air Quality ("DAQ"), Delaware does not agree that its SIP is deficient. Despite this disagreement, the Department has proposed these Amendments to both its regulations and SIP as referenced above, to avoid the imposition of potential federal Clean Air Act ("CAA") sanctions. Delaware has designed the proposed revisions to (1) remove the Director's discretion provisions from the SIP that EPA believes fail to comply with the CAA, (2) comport with EPA guidance and the regulatory structure the EPA has established in other actions, and (3) maintain the elements removed from the SIP as State-only requirements, because Delaware believes the conditions are necessary to administer good air quality management policy. Further, Delaware believes that, from an environmental perspective, the proposed revisions reflect no change at all, because the proposal retains the disputed provisions as State-enforceable-only provisions. Lastly, Delaware opines that, from EPA's perspective, the removal of the offending provisions from the SIP should be considered as SIP strengthening, thus approvable and non-controversial.

The Department has the statutory basis and legal authority to act with regard to the proposed regulatory Amendments and SIP revisions as referenced above, pursuant to 7 Del.C. Chapter 60. The aforementioned proposed Amendments and SIP revisions were initially published in the October 1, 2016 edition of the Delaware Register of Regulations, and were presented and thoroughly vetted by the Department at the public hearing held on October 25, 2016. Members of the public attended that hearing, however, no comment was received by the Department at that time. Consistent with 29 Del.C. §10118(a), the public hearing record remained open for public comment through November 9, 2016, however, none was received during the post-hearing phase of this promulgation. All proper notification and noticing requirements concerning the aforementioned regulatory Amendments and proposed SIP revisions were met by the Department in this matter.

The Department's presiding hearing officer, Lisa A. Vest, prepared a Hearing Officer's Report dated November 21, 2016 ("Report"). The Report documents the proper completion of the required regulatory amendment process, establishes the record, and recommends the adoption of the proposed regulatory Amendments and SIP revisions as attached to the Report as Appendix "B".

Reasons and Conclusions

Based on the record developed by the Department's experts and established by the Hearing Officer's Report, I find that the proposed Amendments to the following existing Delaware regulations: (1) 7 DE Admin. Code 1104, "Particulate Emissions from Fuel Burning Equipment"; (2) 7 DE Admin. Code 1105, "Particulate Emissions from Industrial Process Operations"; (3) 7 DE Admin. Code 1124, "Control of Volatile Organic Compound Emissions"; (4) 7 DE Admin. Code 1142, "Specific Emission Control Requirements", as well as the proposed revisions to the Delaware SIP, are well-supported. Therefore, the recommendations of the Hearing Officer are hereby adopted, and I direct that the same be promulgated as final.

I find that the Department's experts in the Division of Air Quality fully developed the record to support adoption of both the aforementioned regulatory Amendments and SIP revisions. The promulgation of the regulatory Amendments and proposed SIP revisions referenced above will enable the Department to (1) remove the Director's discretion provisions from the SIP that EPA believes fail to comply with the CAA; (2) comport with EPA guidance and the regulatory structure the EPA has established in other actions; (3) maintain the elements removed from the SIP as State-only requirements because Delaware believes the conditions are necessary to administer good air quality management policy, as referenced above; and (4) avoid the imposition of CAA sanctions.

In conclusion, the following reasons and conclusions are entered:

1. The Department has the statutory basis and legal authority to act with regard to the proposed amendments to 7 DE Admin. Code 1104, "Particulate Emissions from Fuel Burning Equipment"; 7 DE Admin. Code 1105, "Particulate Emissions from Industrial Process Operations"; 7 DE Admin. Code 1124, "Control of Volatile Organic Compound Emissions"; and 7 DE Admin. Code 1142, "Specific Emission Control Requirements", as well as the proposed revisions to the Delaware SIP, pursuant to 7 Del.C. Ch. 60;

2. The Department has jurisdiction under its statutory authority, pursuant to 7 Del.C. Ch. 60, to issue an Order adopting these proposed regulatory amendments and SIP revisions as final;

3. The Department provided adequate public notice of the proposed regulatory amendments and SIP revisions, and all proceedings in a manner required by the law and regulations, provided the public with an adequate opportunity to comment on the proposed regulatory amendments and SIP revisions, including at the time of the public hearing held on October 25, 2016, and held the record open through close of business on November 9, 2016, consistent with 29 Del.C. §10118(a), in order to consider public comment on these proposed regulatory amendments before making any final decision;

4. The Department's Hearing Officer's Report, including its established record and the aforementioned recommended regulatory Amendments and proposed SIP revisions as set forth in Appendix "B", are hereby adopted to provide additional reasons and findings for this Order;

5. Promulgation of the aforementioned regulatory Amendments and proposed SIP revisions will enable the Department to (1) remove the Director's discretion provisions from the SIP that EPA believes fail to comply with the CAA; (2) comport with EPA guidance and the regulatory structure the EPA has established in other actions; (3) maintain the elements removed from the SIP as State-only requirements because Delaware believes the conditions are necessary to administer good air quality management policy, as referenced above; and (4) avoid the imposition of CAA sanctions;

6. The Department has reviewed these proposed regulatory amendments in the light of the Regulatory Flexibility Act, consistent with 29 Del.C. Ch. 104 (version applicable to all regulations initially published on or after January 1, 2016), and has selected Exemption "B5" regarding same, as the proposed regulation Amendments are required by federal law. Moreover, the Department believes these proposed regulatory Amendments to be lawful, feasible and desirable, and that the recommendations as proposed should be applicable to all Delaware citizens equally;

7. The Department's proposed SIP revision, as published in the October 1, 2016 Delaware Register of Regulations, and as set forth in Appendix "B" as noted above, is adequately supported, is not arbitrary or capricious, and is consistent with the applicable laws and regulations. Consequently, they are approved as final regulatory amendments, which shall go into effect ten days after its publication in the next available issue of the Delaware Register of Regulations; and

8. The Department shall submit this Order approving as final regulatory amendments to 7 DE Admin. Code 1104, "Particulate Emissions from Fuel Burning Equipment"; 7 DE Admin. Code 1105, "Particulate Emissions from Industrial Process Operations"; 7 DE Admin. Code 1124, "Control of Volatile Organic Compound Emissions"; and 7 DE Admin. Code 1142, "Specific Emission Control Requirements", as well as the proposed revisions to the Delaware SIP, to the Delaware Register of Regulations for publication in its next available issue, and provide such other notice as the law and regulation require and the Department determines is appropriate.

“Basecoat/clearcoat” means a two-step topcoat system in which a highly pigmented, often metallic, basecoat is followed by a clearcoat, resulting in a finish with high-gloss characteristics. It is often used on automotive plastic parts.

"Black coating" means a coating which meets a maximum lightness of 23 units, and has a saturation of less than 2.8, where saturation equals the square root of A² + B². These criteria are based on Cielab color space, 0/45 geometry. For spherical geometry, specular included, the maximum lightness is 33 units.

"Business machine" means a device that uses electronic or mechanical methods to process information, perform calculations, print or copy information or convert sound into electrical impulses for transmission, including devices listed in standard industrial classification numbers 3572, 3573, 3574,3579, and 3661 and photocopy machines, a subcategory of standard industrial classification number 3861.

"Commercial machine" means a device that is used in commercial activities, including, but not limited to, medical, laboratory and entertainment equipment.

"Electric dissipating coating" means a coating that rapidly dissipates a high-voltage electric charge.

"Electrostatic preparation coating" means a coating that is applied to a plastic part solely to provide conductivity for the subsequent application of a prime, a topcoat, or other coating through the use of electrostatic application methods. An electrostatic prep coat is clearly identified as an electrostatic prep coat on its accompanying material safety data sheet.

“EMI/RFI Electromagnetic interference/radio frequency interference shielding coating” means a coating that is used in a plastic business or commercial machine housing to attenuate electromagnetic and radio frequency interference signals that would otherwise pass through the plastic housing.

“Flexible primer” means any coating that is required to comply with engineering specifications for impact resistance, mandrel bend, or elongation as defined by the original equipment manufacturer.

"Fog coat" means a coating that is applied to a plastic part for the purpose of color matching without masking a molded-in texture. A fog coat shall not be applied at a thickness of more than 0.5 mils of coating solids.

"Gloss reducer" means a coating that is applied to a plastic part solely to reduce the shine of the part. A gloss reducer shall not be applied at a thickness of more than 0.5 mils of coating solids.

“High-bake coating” means a coating that is designed to cure at temperatures above 90 degrees Celsius (°C) (194 degrees Fahrenheit [°F]).

“Higher-solids coating” means a coating that contains greater amounts of pigment and binder than a conventional coating. Solids are the non-solvent, non-water ingredients in the coating. A higher-solids coating usually contains more than 60% solids by volume.

“Low-bake coating” means a coating that is designed to cure at temperatures lower than 90°C (194°F).

"Mask coating" means thin film coating applied through a template to coat a small portion of a substrate.

These criteria are based on Cielab color space, 0/45 geometry. For spherical geometry, specula included, the upper limit is 49 units. The maximum lightness varies as the hue moves from violet to orange. This is a natural consequence of the strength of the colorants, and real colors show this effect.

“Solids content” means the non-solvent, non-water ingredients in the coating, which consist of pigments and binders, that do not evaporate and have the potential to form a cured (dry) film. The solids content can be expressed in terms of volume percent or weight percent.

“Specialty coating” means a coating that is used for unusual job performance requirements, usually in small amounts. These products include but are not limited to adhesion primers, resist coatings, soft coatings, reflective coatings, electrostatic prep coatings, headlamp lens coatings, ink pad printing coatings, stencil coatings, texture coatings (automotive), vacuum metalizing coatings, and gloss flatteners.

Automated parts handling systems include, but are not limited to, hoists and conveyors.

“Batch vapor cleaning machine” means a vapor solvent cleaning machine in which individual parts or a set of parts move through the entire cleaning or drying cycle before new parts are introduced into the cleaning machine. The term does not include machines that do not have a solvent/air interface, such as airless and airtight cleaning systems.

“Carbon adsorber” means a bed of activated carbon into which an air/solvent gas-vapor stream is routed and which adsorbs the solvent on the carbon.

“Cold cleaning machine” means a solvent cleaning machine that contains or uses unheated liquid solvent into which parts are placed to remove soils from the surfaces of the parts or to dry the parts. The term does not include machines that do not have a solvent/air interface, such as airless and airtight cleaning systems.

“Downtime mode” means the time period when a solvent cleaning machine is not cleaning or drying parts and the sump heating coils, if present, are turned off.

“Dwell” means the technique of holding parts within the freeboard area but above the vapor zone of a solvent cleaning machine. Dwell occurs after cleaning or drying to allow solvent to drain from the parts or parts baskets back into the solvent cleaning machine.

“Dwell time” means the period of time between when parts or a parts basket is placed in the vapor zone of a batch vapor or in-line vapor cleaning machine and when solvent dripping ceases.

“Freeboard height” means, for a batch cold cleaning machine, the distance from the liquid solvent level to the top of the solvent cleaning machine. For a batch vapor cleaning machine, it is the distance from the solvent/air interface to the top of the solvent cleaning machine, as measured during idling mode. For an in-line cleaning machine, it is the distance from the solvent/air interface to the bottom of the entrance or exit opening, whichever is lower, as measured during idling mode.

“Freeboard ratio” means the ratio of the solvent cleaning machine freeboard height to the smaller interior dimension (length, width, or diameter) of the solvent cleaning machine.

“In-line vapor cleaning machine” means a vapor solvent cleaning machine that uses an automated parts handling system, typically a conveyor, to automatically provide a continuous supply of parts to be cleaned or dried. These units are fully enclosed except for the conveyor inlet and exit portals.

“Primary condenser” means a series of circumferential cooling coils on a vapor cleaning machine through which a chilled substance is circulated or recirculated to provide continuous condensation of rising solvent vapors and, thereby, creating a concentrated solvent vapor zone.

“Reduced room draft” means decreasing the flow or movement of air across the top of the freeboard area of a solvent cleaning machine to less than 15.2 meters per minute (50 feet per minute) by methods including, but not limited to, redirecting fans or air vents to not blow across the cleaning machine, moving the cleaning machine to a corner where there is less room draft, and constructing a partial or complete enclosure around the cleaning machine.

“Soils” means contaminants that are removed from the parts being cleaned. Soils include, but are not limited to, grease, oils, waxes, metal chips, carbon deposits, fluxes, and tars.

“Solvent/air interface” means, for a vapor cleaning machine, the location of contact between the concentrated solvent vapor layer and the air. This location of contact is defined as the mid-line height of the primary condenser coils. For a cold cleaning machine, it is the location of contact between the liquid solvent and the air.

“Solvent cleaning machine” means any device or piece of equipment that uses volatile organic compounds, liquid or vapor, to remove soils from parts or to dry parts. Types of solvent cleaning machines include, but are not limited to, batch vapor, in-line vapor, in-line cold, immersion cold, and remote reservoir cold cleaning machines, as well as, airless cleaning and airtight cleaning systems.

“Superheated vapor system” means a system that heats the solvent vapor, either passively or actively, to a temperature 10oF above the solvent’s boiling point. Parts are held in the superheated vapor before exiting the machine to evaporate the liquid solvent on the parts. Hot vapor recycle is an example of a superheated vapor system.

“Vapor cleaning machine” means a batch or in-line solvent cleaning machine that heats liquid solvent that is used as part of the cleaning or drying cycle. The heated solvent may or may not be boiling. The term does not include machines that do not have a solvent/air interface, such as airless and airtight cleaning systems.

“Vapor up control switch” means a thermostatically controlled switch that shuts off or prevents solvent from being sprayed when there is no vapor. On in-line vapor cleaning machines the switch also prevents the conveyor from operating when there is no vapor.

“Working mode” means the time period when the solvent cleaning machine is actively cleaning or drying parts.

“Working mode cover” means any cover or solvent cleaning machine design that allows the cover to shield the cleaning machine openings from outside air disturbances while parts are being cleaned or dried in the cleaning machine. A cover that is used during the working mode is opened only during parts entry and removal.

“Cutback asphalt” means asphalt cement that has been liquefied by blending with petroleum solvents (diluents). Upon exposure to atmospheric conditions, the diluents evaporate, leaving the asphalt cement to perform its function.

“Emulsified asphalt” means an emulsion of asphalt cement and water that contains a small amount of an emulsifying agent; it is a heterogeneous system containing two normally immiscible phases (asphalt and water) in which the water forms the continuous phase of the emulsion, and minute globules of asphalt form the discontinuous phase.

“Penetrating prime coat” means an application of low-viscosity liquid asphalt to an absorbent surface. It is used to prepare an untreated base for an asphalt surface. The prime coat penetrates the base, plugs the voids, and hardens and helps bind the top to the overlying asphalt course. The penetrating prime coat also reduces the necessity of maintaining an untreated base course prior to placing the asphalt pavement.

34.3 Standards

34.3.1 No person shall cause, allow, or permit the manufacture, mixing, storage, use, or application of cutback asphalts during the ozone season without approval of the Department as provided in 34.3.2 of this regulation.

44.1.6 Any facility that is currently subject to a state or federal rule promulgated pursuant to the Clean Air Act Amendments of 1977 by exceeding an applicability threshold is and shall remain subject to these provisions, even if its throughput or emissions later fall below the applicability threshold.

44.2 Definitions. As used in 44.0 of this regulation, all terms not defined herein shall have the meaning given them in the November 15, 1990 Clean Air Act Amendments (CAAA), or in 2.0 of this regulation.

“Aggregated” means the summation of all process vents within a process that contain VOCs.

“Annual mass emissions total” means the sum of all non-fugitive VOC emissions, evaluated before control, from a vent. Annual mass emissions may be calculated from an individual process vent or from groups of process vents by using the emission estimation equations contained in Appendix K of this regulation and then multiplying this result by the expected duration and frequency of the emission or groups of emissions over the course of a year.

“Average flow rate” means the flow rate averaged over the amount of time that VOCs are emitted during emission events. For the evaluation of average flow rate from an aggregate of sources, the average flow rate is the weighted average of the average flow rates of the emission events and their annual venting time:

Weighted Average Flow Rate =

(44-1)

“Batch cycle” means a manufacturing event of an intermediate or product from start to finish in a batch process.

“Batch process” means a discontinuous process that involves the bulk movement of material through sequential manufacturing steps. Mass, temperature, concentration, and other properties of the material may vary with time and location in the process. Batch processes are typically characterized as "non-steady-state."

"Batch process train" means an equipment train that is used to produce a product or intermediate. A typical equipment train consists of equipment used for the synthesis, mixing, and purification of a material.

“Control device” means an air pollution abatement device, not a device such as a condenser that operates under reflux conditions, which is required for processing.

“Emissions before control” means the VOC emissions total prior to the application of a control device, or if no control device is used, the VOC emissions total. No credit for discharge of VOCs into wastewater shall be considered when the wastewater is further handled or processed with the potential for VOCs to be emitted to the atmosphere.

“Emission event” means a discrete venting episode that may be associated with a single unit of operation. For example, a displacement of vapor resulting from the charging of a vessel with VOCs will result in a discrete emission event that will last through the duration of the charge and will have an average flow rate equal to the rate of the charge. If the vessel is then heated, there will also be another discrete emission event resulting from the expulsion of vapor from the expansion caused by heating. Both emission events may occur in the same vessel or unit operation.

“Process” means, for the purpose of determining RACT applicability, any equipment within a contiguous area that is connected during the course of a year. "Connected" means a link between equipment, whether it is physical, such as a pipe, or whether it consists of a series of steps from which material is transferred from one unit operation to another unit operation.

“Process vent” means a point of emission from a piece of equipment within which a unit operation takes place. Typical process vents from batch processes include condenser vents, vacuum pumps, steam ejectors, and atmospheric vents from reactors and other process vessels. Relief valve discharges and equipment exhaust systems that discharge from unit operations would also be considered process vents.

“Semi-continuous operation” means an operation that is conducted in a steady-state mode but only for finite durations during the course of a year. For example, a steady-state distillation operation that functions for one month would be considered a semi-continuous operation.

“Single unit operation” means a discrete piece of equipment used in a processing step to prepare reactants, facilitate reactions, separate and purify products, or recycle materials.

“Volatility” means a physical property of materials which exhibits the following characteristics: low-volatility materials have a vapor pressure of less than or equal to 75 millimeters (mm) mercury (Hg) (3.0 inches [in] Hg) at 20 degrees Celsius (°C) (68 degrees Fahrenheit [°F]); moderate-volatility materials have a vapor pressure of greater than 75 mm Hg (3.0 in Hg) and less than or equal to 150 mm Hg (6.0 in Hg) at 20°C (68°F); and high-volatility materials have a vapor pressure of greater than 150 mm Hg (6.0 in Hg) at 20°C (68°F). To evaluate VOC volatility for single unit operations that service numerous VOCs or for processes handling multiple VOCs, the weighted average volatility can be calculated using the total amount of each VOC used in a year, and the individual component vapor pressure, as shown in the following equation:

Weighted Average Volatility =

(44-2)

44.3 Standards. Individual vents with an actual average flow rate less than the flow rate calculated using the RACT applicability equations (FR) provided in 44.3.3 of this regulation, as a function of uncontrolled annual VOC emissions (AE), shall reduce VOC emissions by 90%. Vents in aggregate within a batch process having an actual weighted-average flow rate less than FR calculated using the RACT applicability equations in 44.3.3 of this regulation, as a function of AE, shall reduce process VOC emissions by 90%.

44.3.1 Determination of Uncontrolled Annual VOC Emissions (AE). Determination of the uncontrolled annual VOC emissions (AE) may be achieved by developing engineering estimates of the uncontrolled emissions on a batch basis from a process vent, or from a group of process vents within a batch process train, and multiplying these estimates by the potential number of batch cycles per year. Engineering estimates shall follow the guidance provided in Appendix K of this regulation. Alternatively, if an emissions measurement is to be used to measure vent emissions, the measurement must conform with the requirements for measuring the inlet VOC mass flow rate, as described in 44.4.2.2, 44.4.2.3.1 and 44.4.2.3.2 of this regulation.

44.3.2 Determination of Average Flow Rate. To obtain a value for the actual average flow rate of individual vents or the actual weighted-average flow rate of aggregated vents in a batch process, an owner or operator may measure the flow rates or may estimate the flow rates using the estimation guidelines provided in Appendix K of this regulation. If measurements are used to estimate the flow rates, the measurements must conform with the requirements for measuring the incoming volumetric flow rates, as described in 44.4.2.2 of this regulation. If flow rates are estimated using manifold design parameters, the owner or operator shall demonstrate that equipment design accurately reflects actual operating conditions.

44.3.3 RACT Applicability Equations. RACT applicability equations are specific to VOC volatility and are presented below:

(44-3)

where:

FR = Calculated Flow Rate (standard cubic feet per minute [scfm])

AE = Uncontrolled Annual VOC Emissions (pounds per year [lb/yr])

An owner or operator shall compare the calculated flow rate (FR) with the actual average flow rate or the actual weighted-average flow rate determined using the procedures described in 44.3.2 of this regulation, and if FR exceeds the actual average flow rate, the owner or operator shall reduce VOC emissions by 90%.

44.4 Performance Testing.

44.4.1 For the purpose of demonstrating compliance with the control requirements of 44.0 of this regulation, unit operations shall be performed at full operating conditions and flow rates during any performance test.

44.4.2 The following methods in 40 Code of Federal Regulations (CFR) Part 60, Appendix A (July 1, 1992), shall be used to demonstrate that the process vent or vents comply with the control efficiency requirement listed in 44.3 of this regulation.

44.4.2.1 Method 1 or 1A, as appropriate, for the selection of the sampling sites if the flow measuring device is a rotameter. No traverse is necessary when the flow measuring device is an ultrasonic probe. The control device inlet sampling sites for the determination of vent stream VOC composition reduction efficiency shall be located before and after the control device.

44.4.2.2 Method 2, 2A, 2C, or 2D, as appropriate, for the determination of the gas stream volumetric flow rate; flow measurements shall be made continuously.

44.4.2.3 Method 25A or Method 18, if applicable, for the determination of VOC concentration in the control device inlet and outlet.

44.4.2.3.1 The sampling time for each run shall be the entire length of the batch cycle in which readings will be taken continuously, if Method 25A is used, or as often as is possible using Method 18, with a maximum of 1 one-minute intervals between measurements throughout the batch cycle.

44.4.2.3.2 The VOC emission rate of the process vent at the inlet to the control device shall be determined by combining continuous concentration and flow rate measurements at simultaneous points throughout the batch cycle.

44.4.2.3.3 The VOC emission rate of the process vent at the outlet of the control device shall be obtained by combining continuous concentration and flow rate measurements at simultaneous points throughout the batch cycle.

44.4.2.3.4 The efficiency of the control device shall be determined by integrating the mass rates obtained using the procedures specified in 44.4.2.3.2 and 44.4.2.3.3 of this regulation, over the time of the batch cycle, and dividing the difference in the inlet and outlet mass flow totals by the inlet mass flow total.

The TRE index is a decision tool used to determine if the annual cost of controlling a given vent gas stream is acceptable when considering the emissions reduction achieved.

“Vent stream” means any gas stream which discharges directly from a distillation operation or reactor process to the atmosphere or which discharges indirectly to the atmosphere after diversion through other process equipment. The definition of vent stream excludes relief valve discharges and equipment leaks including, but not limited to, pumps, compressors, and valves.

A facility is subject to 50.0 of this regulation if it has sources not regulated by the sections or rules listed above or not regulated as specified in 50.1.4 of this regulation or not exempted as specified in 50.1.5 of this regulation that as a group have maximum theoretical VOC emissions of 25 tons or more per calendar year in New Castle or Kent Counties, or 50 tons or more per calendar year in Sussex County, in the absence of control devices.

50.1.2 The owner or operator of a facility whose emissions are below the applicability threshold in 50.1.1 of this regulation shall comply with the appropriate certification, recordkeeping, and reporting requirements of 50.4 of this regulation.

50.1.3

50.1.3.1 Any facility that becomes or is currently subject to the provisions of 50.0 of this regulation by exceeding the applicability threshold in 50.1.1 of this regulation will remain subject to these provisions even if its throughput or emissions later fall below the applicability threshold.

50.1.3.2 Any facility that is currently subject to a state or federal rule promulgated pursuant to the Clean Air Act Amendments of 1977 by exceeding the applicability threshold is and will remain subject to those provisions, even if its throughput or emissions have fallen or later fall below the applicability threshold.

50.1.4 The control requirements in 50.0 of this regulation do not apply to coke ovens (including by-product recovery plants), fuel combustion sources, barge loading facilities, jet engine test cells, vegetable oil processing facilities, wastewater treatment facilities, and iron and steel production.

50.1.5 The control requirements in 50.0 of this regulation do not apply to the following source categories for which the U.S. EPA must issue Control Technique Guidelines (CTGs) by November 15, 1993 under the non-attainment provisions of Title I of the November 15, 1990 Clean Air Act Amendments:

50.1.5.1 Wood furniture coatings.

50.1.5.2 Industrial wastewater.

50.1.5.3 Shipbuilding and repair.

50.2 Standards. The owner or operator of any source at a facility subject to 50.0 of this regulation shall do one of the following:

50.2.1 Install and operate emission capture and control techniques or, if appropriate, use complying coatings that achieve an overall reduction in VOC emissions of at least 81 weight %. For purposes of 50.2 of this regulation, fugitive emissions from leaks of equipment which resemble the equipment found in the Synthetic Organic Chemical Manufacturing Industry (SOCMI) or Petroleum Refinery Equipment shall not be subject to the requirement for 81 weight % overall control or included in the calculation of 81 weight % provided that the controls and technologies specified in 40.0 (pertaining to SOCMI leaks) or 29.0 (pertaining to Petroleum Refinery Equipment leaks) of this regulation, respectively, are followed. A technical support document, adequately justifying the emission capture and control techniques, shall be submitted to the Department.

50.2.2 For any coating unit, limit the daily-weighted average VOC content to 0.40 kilograms VOC per liter (kg VOC/L) (3.5 pounds VOC per gallon [lb VOC/gal]) or less of coating, as applied (excluding water and exempt compounds), as calculated in Appendix C of this regulation. A technical support document, adequately justifying the daily-weighted average VOC content, as applied, shall be submitted to the Department.

50.2.3 Comply with an alternative control plan that has been approved by the Administrator of the U.S. EPA as part of a State Implementation Plan (SIP) or Federal Implementation Plan (FIP) revision. The alternative control plan shall:

50.2.3.1 Be submitted within six months of the effective date of the rule.

50.2.3.2 Be accompanied by a demonstration of the technical or economic infeasibility of complying with the requirements in 50.2.1 or 50.2.2 of this regulation.

50.3 Test methods and procedures. The owner or operator of any source subject to 50.0 of this regulation shall demonstrate compliance with 50.2 of this regulation by using the applicable test methods specified in Appendix A through Appendix F of this regulation.

50.4 Reporting and Recordkeeping Requirements for Exempt Non-Control Technique Guideline (Non-CTG) Sources.

50.4.1 Coating Sources. An owner or operator of a coating unit that is exempt from the emission limitations in 50.2 of this regulation shall comply with the certification, recordkeeping, and reporting requirements in 4.2 of this regulation.

50.4.2 Non-Coating Sources. An owner or operator of a non-coating source that is exempt from the emission limitations in 50.2 of this regulation shall submit, upon request by the Department records that document that the source is exempt from these requirements.

50.4.2.1 These records shall be submitted to the Department within 30 calendar days from the date of request.

50.4.2.2 If such records are not available, the source is considered to be subject to the limits in 50.2 of this regulation.

50.5 Reporting and Recordkeeping Requirements for Subject Non-CTG Coating Sources.

50.5.1 An owner or operator of a coating unit subject to 50.0 of this regulation and complying with 50.2.1 of this regulation by the use of complying coatings shall comply with the certification, recordkeeping, and reporting requirements in 4.3 of this regulation.

50.5.2 An owner or operator of a coating unit subject to 50.0 of this regulation and complying with 50.2.2 of this regulation by daily-weighted averaging shall comply with the certification, recordkeeping, and reporting requirements in 4.4 of this regulation.

50.5.3 An owner or operator of a coating unit subject to 50.0 of this regulation and complying with 50.2.1 or 50.2.3 of this regulation by using control devices shall comply with the testing, reporting, and recordkeeping requirements in 4.5 of this regulation.

50.6 Reporting and Recordkeeping Requirements for Subject Non-CTG, Non-Coating Sources.

50.6.1 The owner or operator of the subject VOC sources shall perform all testing and maintain the results of all tests and calculations required under 50.2 and 50.3 of this regulation to demonstrate that the subject source is in compliance.

50.6.2 The owner or operator of the subject VOC source shall maintain these records in a readily accessible location for a minimum of five years and shall make these records available to the Department immediately upon verbal or written request.
