Construction Permits By Rule

PURPOSE: This rule creates a process by which sources can be exempt from 10 CSR 10-6.060 Construction Permits Required, by establishing conditions under which specific sources can construct and operate. It establishes notification requirements and standard review fees. It has been determined that these sources will not make a significant contribution of air contaminants to the atmosphere. (1) Applicability. This rule applies to certain types of facilities or changes within facilities listed in this rule where construction is commenced on or after the effective date of the relevant permit-by-rule. To qualify for a permit-by-rule, the following general requirements must be met: (A) Any installation undergoing activities that would other wise be subject to section (7), (8), or (9) of 10 CSR 10-6.060 does not qualify for permit-by-rule under this regulation. Installa tions accepting the permit-by-rule emission limitations can use those limitations to determine whether the installation is subject to section (7), (8), or (9) of 10 CSR 10-6.060; (B) The installation is not prohibited from permit-by-rule by permit conditions, by settlement agreements or by official notification from the director; (C) All emission control equipment associated with the permit-by-rule shall be maintained and operated in accordance with the equipment specifications of the manufacturer; (D) Obtaining a permit-by-rule under this regulation does not exempt an installation from other applicable air pollution regulations or any local air pollution control agency require ments; and (E) The director may require an air quality analysis in ad dition to the general requirements listed in subsection (3)(B) of this rule if it is likely that the emissions of the proposed construction or modification will appreciably affect air quality or the air quality standards are being appreciably exceeded or complaints filed in the vicinity of the proposed construction or modification warrant an air quality analysis. The permitby-rule may be revoked if it is determined that emissions from the source interfere with the attainment or maintenance of ambient air quality standards. (2) Definitions. (A) As applied—The volatile organic compound (VOC) and solids content of the finishing material that is actually used for coating the substrate. It includes the contribution of materials used for in-house dilution of the finishing material. (B) Closed container—A container with a cover fastened in place so that it will not allow leakage or spilling of the contents. RESOURCES (C) Construction—Fabricating, erecting, reconstructing, or installing a source operation. Construction includes installation of building supports and foundations, laying of underground pipe work, building of permanent storage structures, and other construction activities related to the source operation. (D) Incinerator—Any article, machine, equipment, contrivance, structure, or part of a structure used to burn refuse or to process refuse material by burning other than by open burning. (E) Malfunction—A sudden and unavoidable failure of air pollution control equipment or process equipment or of a process to operate in a normal and usual manner. Excess emissions caused by improper design shall not be deemed a malfunction. (F) Manure storage and application systems—Any system that includes, but is not limited to lagoons, manure treatment cells, earthen storage ponds, manure storage tanks, manure stockpiles, composting areas, pits and gutters within barns, litter used in bedding systems, all types of land application equipment, and all pipes, hoses, pumps, and other equipment used to transfer manure. (G) Material safety data sheet—The chemical, physical, technical, and safety information document supplied by the manufacturer of the coating, solvent, or other chemical product. (H) Opacity—The extent to which airborne material obstructs the transmission of incident light and obscures the visual background. Opacity is stated as a percentage of light obstructed and can be measured by a continuous opacity monitoring system or a trained observer. An opacity of one hundred percent (100%) represents a condition in which no light is transmitted, and the background is completely obscured. (I) Printing—Any operation that imparts color, images, or text onto a substrate using printing inks. (J) Responsible official—Includes one (1) of the following: 1. The president, secretary, treasurer, or vice-president of a corporation in charge of a principal business function, any other person who performs similar policy and decisionmaking functions for the corporation, or a duly authorized representative of this person if the representative is responsible for the overall operation of one (1) or more manufacturing, production, or operating facilities applying for or subject to a permit and either— A. The facilities employ more than two hundred fifty (250) persons or have a gross annual sales or expenditures exceeding twenty-five (25) million dollars (in second quarter 1980 dollars); or B. The delegation of authority to this representative is approved in advance by the permitting authority; 2. A general partner in a partnership or the proprietor in a sole proprietorship; 3. Either a principal executive officer or ranking elected official in a municipality or state, federal, or other public agency.

The designated representative of an affected source insofar as actions, standards, requirements, or prohibitions under Title IV of the Act or the regulations promulgated under the Act are concerned and the designated representative for any other purposes under part 70. (K) Sludge—Any solid, semisolid, or liquid waste generated from a municipal, commercial, or industrial wastewater treatment plant, water supply treatment plant, or air pollution control facility, exclusive of the treated effluent from a wastewater treatment plant. (L) Definitions of certain terms used in this rule, other than those specified in this rule, may be found in 10 CSR 10-6.020. (3) General Provisions. (A) Registration. To qualify for a permit-by-rule, the owner or operator must notify the Missouri Department of Natural Resources’ Air Pollution Control Program prior to commence ment of construction. This notification will establish the permit-by-rule and become the conditions under which the facility is permitted. All representations made in the notifi cation regarding construction plans, operating procedures, and maximum emission rates shall become conditions upon which the facility shall construct or modify. If the conditions, as represented in the notification, vary in a manner that will change the method of emission controls, the character of the emissions, or will result in an increase of emissions, a new noti fication or permit application must be prepared and submitted to the department’s Air Pollution Control Program. 1. The director shall provide a form by which operators can submit their notifications. The notification shall include documentation of the basis of emission estimates or activity rates and be signed by a responsible official certifying that the information contained in the notification is true, accurate, and complete. The expected first date of operation shall be included in the notification. 2. The notification shall be sent to the department’s Air Pollution Control Program. Two (2) copies of the original notification shall be made. One (1) shall be sent to the appropriate regional office, and one (1) shall be maintained onsite and be provided immediately upon request by inspectors. 3. Fees. A review fee must accompany the notification sent to the department’s Air Pollution Control Program. The review fee amount is found in 10 CSR 10-6.025(4). 4. Upon receiving the notification, the department shall complete a pre-construction review of the notification and make an approval/disapproval determination within seven (7) business days. If the notification is approved by the department, the operator may begin construction and operation of the new source. (B) Permit-by-Rule. 1. Printing operations.

Livestock markets and livestock operations. Any livestock market or livestock operation including animal feeding operations and concentrated animal feeding operations as those terms are defined by 40 CFR 122.23, that was constructed after November 30, 2003, and operates in compliance with the following conditions is permitted under this rule. In addition, any manure storage and application system directly associated with the livestock markets or livestock operations such that these manure storage and application systems are operated in compliance with the following conditions are also permitted under this rule: A. All facilities implement the following building cleanliness and ventilation practices: (I) Buildings are cleaned thoroughly between groups of animals; (II) Manure and spilled feed are scraped from aisles on a regular basis, at least once per week; (III) Ventilation fans, louvers, and cowlings are regularly cleaned to prevent excessive buildup of dust, dirt, or other debris that impairs performance of the ventilation system; (IV) Air inlets are cleaned regularly to prevent excessive buildup of dust, dirt, or other debris that reduces airflow through the inlets; (V) Ceiling air inlets are adjusted to provide adequate airflow (based on design ventilation rates) to the building interior; (VI) For high-rise structures, the manure storage area includes engineered natural or mechanical ventilation. This ventilation must be maintained and cleaned regularly to prevent excessive buildup of dust, dirt, or other debris that impairs performance of the ventilation system; (VII) For deep-bedded structures, bedding and/or litter used in the animal living area is maintained in a reasonably clean condition. Indications that the bedding is not reasonably clean include extensive caking, manure coating animals or birds, and the inability to distinguish bedding material from manure. Bedding or litter with excessive manure shall be removed and replaced with clean bedding or litter; and (VIII) For automatic feed delivery systems, feed lines have drop tubes that extend into the feeder to minimize dust generation; B. All facilities implement the following manure storage practices: (I) Buildings with flush alleys, scrapers, or manure belts are operated to remove manure on a regular schedule, at least daily; (II) Buildings with shallow pits, four feet (4') deep or less, are emptied on a regular schedule, at least once every fourteen (14) days; (III) Feed, other than small amounts spilled by the animals, is not disposed of in the manure storage system; (IV) All lagoons are regularly monitored for solids buildup, at least once every five (5) years. Lagoon sludge shall be removed and properly disposed of when the sludge volume equals the designed sludge volume; and (V) Manure compost piles or windrows are turned or otherwise mixed regularly so that the temperature within the pile or windrow is maintained between one hundred five degrees Fahrenheit (105°F) and one hundred fifty degrees Fahrenheit (150°F); C. The operator considers wind direction and velocity when conducting surface land application, and manure is not applied within five hundred (500') feet from a downwind inhabited residence; D. Dead animals are not disposed of in the manure storage system unless the system is specifically designed and managed to allow composting of dead animals. Dead animals shall be removed from buildings daily; and E. Recordkeeping. (Not Applicable) (C) Revocation. 1. A permit-by-rule may be revoked upon request of the operator or for cause. For purposes of this paragraph, cause for revocation exists if— A.
