1. Title of the Regulations:

Amendment to Regulation 1138 Emission Standards for Hazardous Air Pollutants for Source Categories

2. Brief Synopsis of the Subject, Substance and Issues:

Under Section 112(k) of the 1990 Clean Air Act Amendments, Congress mandated that the EPA identify 30 or more hazardous air pollutants (HAPs) that posed the greatest threat to public health in urban areas, to identify the small area sources that emit those pollutants and to develop regulations to reduce the emission of HAPs. In 1999, the EPA identified 33 HAPs that posed the greatest threat to public health and has, since that time, identified over 60 new area source categories for which regulations are being developed.

In July 2008, the EPA promulgated another of these area source category standards that will affect existing and future Delaware sources; the area source standard for plating and polishing operations under 40 CFR Part 63 Subpart WWWWWW.

Delaware is proposing to amend Regulation 1138 by adding a new Section 10 that covers plating and polishing operations. The purpose of this proposed amendment is to provide increased protection for Delaware citizens against a variety of potential adverse health effects linked to a long term exposure to cadmium, chromium, lead, manganese, or nickel compounds. In addition, all of these compounds, except the manganese compounds, are classified as known or probable human carcinogen by the EPA. The proposed amendment will provide greater consistency between Delaware’s air toxics standards and the recently promulgated federal standard (40 CFR Part 63 Subpart WWWWWW) on which this proposed amendment is heavily based. In addition, this amendment proposes to include more health protective requirements that currently exist in similar air standards found in Regulation 1138 and other Delaware air regulations.

3. Possible Terms of the Agency Action:

None

4. Statutory Basis or Legal Authority to Act:

7 Delaware Code, Chapter 60

5. Other Regulations That May Be Affected By The Proposal:

None

6. Notice of Public Comment:

Code 1130 of State of Delaware "Regulations Governing the Control of Air Pollution", if the owner or operator is not required to obtain a Title V operating permit under 3.1 of 7 DE Admin. Code 1130 for a reason other than the owner or operator's status as an area source under 10.0. Notwithstanding the previous sentence, the owner or operator shall continue to comply with the provisions of 10.0.

10.2 Definitions.

Unless defined below, all terms in 10.0 of this regulation have the meaning given them in the Act or in 3.2 of this regulation.

"Batch electrolytic process tank" means a tank used for an electrolytic process in which a part or group of parts, typically mounted on racks or placed in barrels, is immersed in an electrolytic process tank bath as a single unit (i.e., as a batch) for a predetermined period of time, during which none of the parts are removed from the tank and no other parts are added to the tank, and after which the part or parts are removed from the tank as a unit.

"Bath" means the liquid contents of a process tank that is used for metal coating operations located at a plating and polishing operation.

"Capture system" means the collection of components used to capture gases and fumes released from one or more emission points and then to transport the captured gas stream to a control device. A capture system may include, but is not limited to, the following components as applicable to a given capture system design: duct intake devices, hoods, enclosures, ductwork, dampers, manifolds, plenums, and fans.

"Cartridge filter" means a type of control device that uses perforated metal cartridges containing a pleated paper or non-woven fibrous filter media to remove particulate matter (PM) from a gas stream by sieving and other mechanisms. Cartridge filters can be designed with single use cartridges, which are removed and disposed after reaching capacity, or continuous use cartridges, which typically are cleaned by means of a pulse-jet mechanism.

"Composite mesh pad" means a type of control device similar to a mesh pad mist eliminator except that the device is designed with multiple pads in series that are woven with layers of material of varying fiber diameters, which produce a coalescing effect on the droplets or PM that impinge upon the pads.

"Continuous electrolytic process tank" means a tank used for an electrolytic process and in which a continuous metal strip or other type of continuous substrate is fed into and removed from the tank continuously. This process is also called reel-to-reel electrolytic plating.

"Control device" means equipment used to collect or reduce the quantity of a pollutant that is emitted to the air. The control device receives emissions that are transported from the process by the capture system.

"Control system" means the combination of a capture system and a control device. The overall control efficiency of any control system is a combination of the ability to capture the air emissions (i.e., the capture efficiency) and the control device efficiency. Consequently, it is important to achieve good capture to ensure good overall control efficiency.

"Cyanide electrolytic process tank" means an electrolytic process tank used for cyanide electrolytic processes.

"Cyanide electrolytic process" means an electrolytic process that uses cyanide as a major bath ingredient, that operates at pH of 12 or more, and that uses or emits any of the plating and polishing metal HAPs. The cyanide in the bath works to dissolve the metal HAP added as a cyanide compound (e.g., cadmium cyanide) and creates free cyanide in solution, which helps to corrode the anode. These tanks are self-regulating to a pH of 12 due to the caustic nature of the cyanide bath chemistry. The cyanide in the bath is a major bath constituent and not an additive; however, the self-regulating chemistry of the bath causes the bath to act as if wetting agents/fume suppressants are being used and to ensure an optimum electroplating process. All cyanide electroplating baths at pH greater than or equal to 12 have cyanide-metal complexes in solution. The metal HAP to be plated is not emitted because it is either bound in the metal-cyanide complex or reduced at the cathode to elemental metal, and plated onto the immersed parts. Cyanide baths are not intentionally operated at pH less 12 since unfavorable electroplating conditions would occur in the tank.

"Deviation" means any instance in which an affected source or an owner or operator of an affected source:

"Dry mechanical polishing" means a process used for removing defects from or smoothing the surface of finished metals or formed products after electroplating with any of the plating and polishing metal HAPs using hard-faced abrasive wheels or belts and where no liquids or fluids are used to trap the removed metal particles.

"Electroforming" means an electrolytic process that uses or emits any of the plating and polishing metal HAPs that is used for fabricating metal parts. This process is essentially the same as electroplating except that the plated substrate or mandrel is removed, leaving only the metal plate. In electroforming, the metal plate is self-supporting and generally thicker than in electroplating.

"Electroless plating" means a process that uses or emits any of the plating and polishing metal HAPs in which metallic ions in a tank bath are reduced to form a metal coating at the surface of a catalytic substrate without the use of external electrical energy. Electroless plating is also called non-electrolytic plating.

"Electrolytic process" means a process that uses or emits any of the plating and polishing metal HAPs in which metallic ions in a tank bath are reduced to form a metal coating on or to remove a metal coating from the surface of parts or products using electrical energy.

"Electrolytic process tank" means a process tank in which electrolytic processes occur. This term does not include tanks containing solutions that are used to rinse or wash parts prior to placing the parts in the electrolytic process tank or subsequent to removing the parts from the electrolytic process tank. This term also does not include thermal spraying or dry mechanical polishing.

"Electroplating" means an electrolytic process that uses or emits any of the plating and polishing metal HAPs in which metal ions in a tank bath are reduced onto the surface of the work piece (the cathode) via an electrical current. The metal ions in the tank bath are usually replenished by the dissolution of metal from solid metal anodes fabricated of the same metal being plated, or by direct replenishment of the tank bath with metal salts or oxides. Electroplating is also called electrolytic plating.

"Electropolishing" means an electrolytic process that uses or emits any of the plating and polishing metal HAPs in which a work piece is attached to an anode immersed in a bath, and the metal substrate is dissolved electrolytically, thereby removing the surface contaminant. Electropolishing is also called electrolytic polishing.

"Fabric filter" means a type of control device used for collecting PM by filtering a gas stream through a filter or filter media. A fabric filter is also known as a baghouse.

"Flash or short-term electrolytic process tank" means an electrolytic process tank in which flash or short-term electroplating occurs.

"Flash or short-term electroplating" means an electrolytic process that uses or emits any of the plating and polishing metal HAPs and that is used no more than three cumulative minutes per hour or no more than one cumulative hour per day.

"HAP" means any air pollutant listed in or pursuant to Section 112(b) of the Act. HAPs are also called air toxics. The five plating and polishing metal HAPs are listed in Section 112(b).

"High efficiency particulate air (HEPA) filter" means a type of control device that uses a filter composed of a mat of randomly arranged fibers and is designed to remove at least 99.97% of airborne particles that are 0.3 micrometers or larger in diameter.

"Mesh pad mist eliminator" means a type of control device that uses layers of interlocked filaments densely packed between two supporting grids to remove liquid droplets and PM from the gas stream through inertial impaction and direct interception.

"Metal coating operation" means any process performed either in a process tank that contains liquids or as part of a spraying operation that applies one or more plating and polishing metal HAPs to parts or products used in manufacturing. These processes include, but are not limited to, non-chromium electroplating, electroforming, electropolishing, other non-electrolytic metal coating processes, such as chromate conversion coating, nickel acetate sealing, sodium dichromate sealing, and manganese phosphate coating, and thermal spraying.

"Non-chromium electroplating" means an electroplating process that uses or emits any of the plating and polishing metal HAPs that is not subject to the provisions of 6.0 of this regulation.

"Non-cyanide electrolytic process" means an electrolytic process that uses or emits any of the plating and polishing metal HAPs performed without cyanide in the tank. This process does not use cyanide in the process tank and operate at pH values less than 12. This process uses electricity and adds or removes metals such as plating and polishing metal HAPs from parts or products used in manufacturing.

"Non-cyanide electrolytic process tank" means a tank used for non-cyanide electrolytic processes.

"Packed-bed scrubber" means a type of control device that includes a single or double packed-bed that contains packing media on which PM and droplets impinge and are removed from the gas stream. The packed-bed section of the scrubber is followed by a mist eliminator to remove any water entrained from the packed-bed section.

"Permanent thermal spraying" means a thermal spraying operation that is not a temporary thermal spraying operation.

"Plating and polishing operation" means an operation that uses or emits any of the plating and polishing metal HAPs and is engaged in one or more of the following:

"Plating and polishing metal HAPs" means compounds of any of the following metals: cadmium, chromium, lead, manganese, and nickel, or any of these metals in the elemental form, with the exception of lead. Any material that does not contain cadmium, chromium, lead, or nickel in amounts greater than or equal to 0.1% by weight and does not contain manganese in amounts greater than or equal to 1.0% by weight, as reported on the Material Safety Data Sheet for the material, is not considered to be a plating and polishing metal HAP.

"PM" means solids or particulate matter that is emitted into the air.

"Research and development process tank" means any process tank that is used for conducting research and development for new processes and products and is not used to manufacture products for commercial sale, except in a de minimis manner.

"Surface cover" means a solid structure or combination of structures, made of an impervious material that is designed to cover at least 75% of the open surface area of a continuous electrolytic process tank.

"Tank cover" means a solid structure made of an impervious material that is designed to cover the entire open surface of a batch electrolytic process tank or a flash or short-term electrolytic process tank.

"Temporary thermal spraying" means a thermal spraying operation that uses or emits any of the plating and polishing metal HAPs that lasts no more than one hour in duration during any one day, and that is conducted in situ. Thermal spraying that is conducted in a dedicated thermal spray booth or structure is not considered to be temporary thermal spraying.

"Thermal spraying" means a process that uses or emits any of the plating and polishing metal HAPs in which a metallic coating is applied by projecting molten or semi-molten metal particles onto a substrate. Commonly used thermal spraying methods include high velocity oxy-fuel spraying, flame spraying, electric arc spraying, plasma arc spraying, and detonation gun spraying. This process is also called metal spraying or flame spraying.

"Water curtain" means a type of control device that draws a gas stream through a continuous curtain of moving water to collect and remove suspended PM from the gas stream.

"Wetting agent/fume suppressant" means any chemical agent that reduces or suppresses fumes or mists from an electrolytic process tank by reducing the surface tension of the tank bath.
