17.1 Applicability.

17.1.1 The provisions of 17.0 of this regulation apply to each prepared feeds manufacturing facility that is an area source of hazardous air pollutant (HAP) emissions and uses a material containing chromium or a material containing manganese.

17.1.2 An area source of HAP emissions is a source of hazardous air pollutants (HAPs) that is not a major source of HAP emissions, is not located at a major source of HAP emissions, and is not part of a major source of HAP emissions. A major source of HAP emissions is any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit considering controls, in aggregate, 10 tons per year or more of any HAP or 25 tons per year or more of any combination of HAPs.

17.1.3 The provisions of 17.0 of this regulation apply to each new and existing prepared feeds manufacturing affected source. A prepared feeds manufacturing affected source is the collection of all equipment and activities necessary to produce animal feed from the point in the process where a material containing chromium or a material containing manganese is added, to the point where the finished animal feed product leaves the facility. This includes, but is not limited to, areas where a material containing chromium or a material containing manganese is stored, areas where a material containing chromium or a material containing manganese is temporarily stored prior to addition to the feed at the mixer, mixing, and grinding processes, pelleting and pellet cooling processes, packing and bagging processes, crumblers and screens, bulk loading operations, and all conveyors and other equipment that transfer the feed materials throughout the manufacturing facility.

17.1.3.1 A collection of equipment and activities necessary to produce animal feed at a prepared feeds manufacturing facility becomes an affected source when the owner or operator commences using a material containing chromium or a material containing manganese.

17.1.3.2 A collection of equipment and activities necessary to produce animal feed at a prepared feeds manufacturing facility ceases to be an affected source when the facility stops using materials containing chromium and materials containing manganese and submits a notification of change of status to the Department in accordance with 17.7.3 of this regulation.

17.1.4 A prepared feeds manufacturing affected source is an existing affected source if the owner or operator commenced construction or reconstruction on or before July 27, 2009.

17.1.5 A prepared feeds manufacturing affected source is a new affected source if the owner or operator commenced construction or reconstruction after July 27, 2009.

17.1.6 The facilities identified in 17.1.6.1 and 17.1.6.2 of this regulation are exempt from the provisions of 17.0 of this regulation.

17.1.6.1 Prepared feeds manufacturing facilities that do not add any materials containing chromium or any materials containing manganese to any product manufactured at the facility.

17.1.6.2 Prepared feeds manufacturing operations conducted in research or laboratory facilities.

17.1.7 The owner or operator of an area source subject to 17.0 of this regulation is exempt from the obligation to obtain a Title V operating permit under 7 DE Admin. 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 17.0. Notwithstanding the previous sentence, the owner or operator shall continue to comply with the provisions of 17.0.

17.2 Definitions.

Unless defined below, all terms in 17.0 of this regulation have the meaning given them in the Act or in 3.2 of this regulation.

“Animal feed” includes: dehydrated alfalfa meal; alfalfa prepared as feed for animals; cubed alfalfa; chopped, crushed, or ground barley feed; prepared bird feed; blended animal feed; bone meal prepared as feed for animals and fowls; cattle feeds, supplements, concentrates, and premixes; prepared chicken feeds; cattle feed citrus pulp; complete livestock feed; custom milled animal feed; dairy cattle feeds supplements, concentrates, and premixes; earthworm food and bedding; animal feed concentrates; animal feed premixes; animal feed supplements; prepared animal feeds; specialty animal (e.g., guinea pig, mice, mink) feeds; fish food for feeding fish; custom ground grains for animal feed; cubed hay; kelp meal and pellets animal feed; laboratory animal feed; livestock feeds, supplements, concentrates and premixes; alfalfa meal; livestock micro and macro premixes; mineral feed supplements; animal mineral supplements; pet food; poultry feeds, supplements, and concentrates; rabbit food; shell crushed and ground animal feed; swine feed; swine feed supplements, concentrates, and premixes; and prepared turkey feeds. Feed products produced for dogs and cats are not considered animal feed for the purposes of 17.0 of this regulation.

“Average daily feed production level” means the average amount of animal feed products produced each day over an annual period. For existing sources, the initial average daily feed production level is based on the average daily feed production level determination for the period of January 5, 2011 through January 4, 2012. For new sources, the initial average daily feed production level is based on the design rate. Subsequently, average daily feed production levels are determined annually and are based on the amount of animal feed products produced in a calendar year divided by the number of days in which the production processes were in operation.

“Cyclone” means a mechanically aided collector that uses inertia to separate particulate matter from the gas stream as it spirals through the cyclone.

“Deviation” means any instance in which an affected source, subject to 17.0 of this regulation, or an owner or operator of such a source fails to meet any applicable requirement or obligation established in 17.0.

“Material containing chromium” means a material that contains chromium (Cr, atomic number 24) in amounts greater than or equal to 0.1% by weight.

“Material containing manganese” means a material that contains manganese (Mn, atomic number 25) in amounts greater than or equal to 1.0% by weight.

“Pelleting operations” means all operations that make pelleted animal feed, including but not limited to, steam conditioning, die-casting, drying, cooling, crumbling, and granulation.

“Prepared feeds manufacturing facility” means a facility that is primarily engaged in manufacturing animal feed. A facility is primarily engaged in manufacturing animal feed if the production of animal feed comprises greater than 50% of the total production of the facility on an annual basis. Facilities primarily engaged in raising or feeding animals are not prepared feed manufacturing facilities. Facilities engaged in the growing of agricultural crops that are used in the manufacturing of animal feed are not considered prepared feeds manufacturing facilities.

“Research and laboratory facility” means any stationary source whose primary purpose is to conduct research and development into new processes and products, where such source is operated under the close supervision of technically trained personnel and is not engaged in the manufacture of products for commercial sale in commerce, except in a de minimis manner.
