1. TITLE OF THE REGULATIONS:
Revision to Section 36 “Stage II Vapor Recovery” of 7 DE Admin. Code 1124 “Control of Volatile Organic Compound Emissions.”
2. BRIEF SYNOPSIS OF THE SUBJECT, SUBSTANCE AND ISSUES:
Gasoline vapors contribute to the formation of ground-level ozone pollution, and include hazardous air pollutants. Delaware has implemented, since 1993, Stage II vapor recovery requirements to control gasoline vapor emissions from motor vehicle fueling at gasoline dispensing facilities. In addition, since 1998, automobile manufacturers have been required by the federal clean air act to install on-board refueling vapor recovery (ORVR) systems on new motor vehicles. Now that a large percentage of vehicles on Delaware roads are equipped with ORVR systems DNREC is proposing a regulation revision to begin the phase out of Stage II vapor recovery in Delaware.
DNREC is proposing to revise Section 36 of 7 DE Admin. Code 1124 to allow new or modified gasoline stations the option to not install Stage II vapor recovery systems, and to instead install an enhanced Stage I vapor recovery system, and to either 1) conduct enhanced monthly inspections and pressure decay leak testing or, 2) participate in a 1-year trial to demonstrate whether or not a continuous pressure monitoring (CPM) system is able to accurately identify system leaks and times when emissions are being vented from the pressure/vacuum valve. DNREC plans to revise this regulation again in the future based on the data obtained from the trial tests. DNREC hereby withdraws the proposed regulation that was published in the August 2014 Delaware Register.
3. POSSIBLE TERMS OF THE AGENCY ACTION:
None.
4. STATUTORY BASIS OR LEGAL AUTHORITY TO ACT:
7 Del.C., Chapter 60, Environmental Control
5. OTHER REGULATIONS THAT MAY BE AFFECTED BY THE PROPOSAL:
None
6. NOTICE OF PUBLIC COMMENT:
A public hearing will be held on June 25, 2015, beginning at 6:00 pm, in DNREC Auditorium, 89 Kings Highway, Dover, DE 19901.

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.

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 =
“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 =
44.3 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:
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.
