HomeMy WebLinkAboutOrdinance 723 (2) AMBIENT AIR QUALITY STANDARDS AND AIR PO~UTION CONTROL REGULATIONS The following air quality standards and emission regulations apply to any source or emission located partially or v~olly w-lthin the state of Minnesota. Regulations are of general application throughout the state unless specifically indicated otherwise by their context. The official policy and purpose of the state of Minnesota in regard to air quality control is set forth in Miunesota Statutes 1967: Section 116.07, Subd. 2~ The pollution control agency shall adopt standards of air quality, including maximum allowable standards of emission of air contaminants from motor vehicles, recogniz~ that due to variable factors, no single standard of purity of air is applicable to all areas of the state. ID adopting standards, the pollution control agency shall give due recognition to the fact that the quantity or characteristics of air contaminants or the duration of their presence in the atmosphere, which may cause air pollution in one area of the state, may cause less or not cause ~y air pollution in another area of the state, and it shall take into consideration in this co~n~ection such factors, including others which it may deem proper, as existing physical conditions, zonLng classifications, topography, prevailing wind direction and velocities, and the fact that a standard of air quality which may be proper as to an essentially residential area of the state, may not be proper as to a highly developed industrial srea of the state. Such standards of air quality shall be premised upon scientific knowledge of causesas well as effects based on technically sub- stantiated criteria ~d commonly accepted practices. Subd. ~. Pursuant and subject to the provisions of chapter 15, and the pro~sions hereof, the pollution control agency may adopt, amend, and rescLnd regulations and standards having the force of law relating to any purpose within the provisions of this act for the prevention, abatement, or control of air pollution. Any such regulation or standard may be of general application throughout the state or may be limited as to times, places, circumstances, or conditions in order to make due allowance for variations therein. Without limitation, regulations or standards may relate to sources of emissions of air contamination or air pollution, to the quality or composition of such emissions, or to the quality of or composition of the ambient air or outdoor atmosphere or to any other matter relevant to the preven- tion, abatement, or control of air pollution. Subd. 5. The pollution' control agency may grm'~t variances from the requirements of regulations or standards upon such procedure m~d conditions as it may by regulation prescribe in order to avoid undue hardship and promote the effective and reasonable application and enforcement of the laws~ regulations, and standards for prevention, abatement, and control of air pollution. Subd. 6. In exercising all its powers the pollu- tion control agency shall give due consideration to the establishment.~ maJn~ten~ce, operation and exp~sion of business commerce, trade, industry, traffic~ and other economic factors and other material matters affecting the feasibility and practicability of any proposed action, including, but not limited to, the burden on a municipality of any tax which may res~lt therefrom, and shall take or pro~lde for such action as m~y be reasonable, feasible, and practical under the cir~mnstances. Consistent with these objectives, it shall be the po~.cy of the Pollution Control Agency that new equipment capabl~ of becoming a source of air pollu- tion be provided with the maximum control capability which is technically practicable ~and economically reasonable. The Pollution Control Agency shall encourage the development and expansion of air pollution control programs in cities~ counties and other political subdivisions of the state and provide planning, technical and enforcement assistance. 2&2-2 APO I ~I~2~T AIR QUALITY STEWARDS The £ollow~mg air qus~lity standards are desirable levels of air quality which on the basis of present knowledge are not expected to produce health hazards or impairment, injury to agricultural crops and livestock, dam_~ge to or deterioration of property, s~d hazards to air and ground transportation. Health hazards include not only production, aggravation or possible production of disease, but also interference with function. Health impairment includes sensory irritation and impairment of well being by such phenomena as odor. The standards are based on review and interpretation of data on air pollution exposures and associated effects and appropriate Federal air quality criteria. Standards of air quality are not, however, intended to provide a sharp dividing line between air of satisfactory quality and air of unsatisfactory quality.

(i) This regulation applies to fuel burning installations utilized for the primary purpose of produc~%¢ steam, hot water, hot air or other indirect heating of liquids, gases, or solids where the products of combustion do not have direct contact with process materials. Fuel includes coal, coke, lignite, coke breeze, fuel oil, and wood, but does not include refuse. When any products or by-products of a manufacturing process are burned for the same purpose or in conjunction with any fuel, the same maximum emission li~-¢itations shall apply. (2) Heat content of coal shall be dete~uined according to American Society for Testing and Materials method D-271-6& Laborato~7 Sampling and Analysis of Coal and Coke or method D-2015-62T Gross Calorific Value of Solid Fuel by the Adiabatic Bomb Calorimeter, which publications are incorporated herein by reference. (3) As used herein "heat input" shall be the aggregate heat content of all fuels whose combustion products pass through a stack or stacks. ?de heat ~-uput value used shall be the equipment manufacturer's or designer:s guaranteed maximum input, whichever is greater. The total heat input of all fuel burring units at an installation or on a premises shall determine the maximum allowable amount of particulate matter emission. (~) Particulate matter emission shall be measured according to the American Society of Mechanical Engineers Power Test Code - PTC - 27 dated 1957 and entitled Determining Dust Concentration in a Gas Stream, which publication is incorporated herein by reference, or other approved method conducted in accordance with good professional practice. B. Provision for Minneapolis-~St. Paul Metropolitan Area and All New Installations. Emimmions of particulate matter from the combustion of fuel for indirect heating shall be limited by the provisions of the American Society of Mechanical Engineers Standard No. APS-1 dated June 15, 1966: "Recommended Guide for the Control of Dust Emission-Combustion for Indirect Heat Exchangers." #24~2-13 4.1 Figure 2 in such standard shall be used to esti~ate allowable emissions from a plant with a sir~le stack. The appropriate correction factor sh~ll be applied to multiple stack plants or instal3mations. Regardless of stack number or height, the maximum allowable emission for ar5~ stack, plant or installation shall be 0.6 pounds of particulates per million BTU input. C. Provision for Existing Plants or Installations Outside the Minneapolis-St. Paul Metropolitan Area. Particulate matter emissions from the combustion of fuel for indirect heating shall be limited as in B above, except, regardless of stack number or height, the maximum allowable emission for any stack, plant or installation shall be 0.8 pounds of particulates per million BTU input. D. Smoke Indicators. It is recommended plants or installations b'arnLug solid fuel or liquid fuels of Grades 5 or 6 (PS No. 300 or PS No. 400) and hav~g more than 1,O00,O00 BTU input capacity be equipped with smoke indicators, mirrors, or similar approved de¥ices to enable the fireman to observe the breaching or the top of the stack or stacks from the boiler room at all times, unless the top of the stack is readily visible to the firemau from the boiler room without the use of such devices. In plants where a fireman is not in constant attendance in the boile~ room, and when the boilers fired at one time aggregate more than 1,000 square feet of heating surface the smoke indicators should be capable of sounding an alarm or flashing a signal to attract the attention of the fireman. Any existing plant or installa- tion which emits smoke of a density greater than permitted by appropriate re- gulation shall install such indicating devices. /s~ John P. Badalich John P.

General Provisions (t) This regulation applies to any operation, process, or activity except the bur~ing of fuel for indirect heating where the products of combustion do not directly contact process materials, except refuse burning and princess burning of salvageable material. (2) "Process'va~ight" shall have the meaning ascribed to it in regulation APC 2. Process weight rate for cont~nuo~s or long-~n steady-share so,zrces shall be the total process weight for the er~tm~e pe~:~od of cor~t~nuous operation or a typic al portion thereof, divided by the number of hours or such ~eriod or portion thereof. Process weight rate for cyclical or batch source shall be the total process weight for a period which covers a con~lete operation or an integral number of cycles, divided by the hours of actual process operation during such period. Where the nature of any process or operation or the design of any equipment admits more than one interpretation of this section, the in--ration resulting in the minimum allowable emission v~lue shall apply. (3) Emission tests for determination of compliance with this regulation shall follow the standards in American Society of Mechar~ Engineers Power Test Code - PTC - 27 dated 1957 and entitled "D~termin~ D'ust Concentration in a Gas Stream" or other approved method. B. Emission Limitations. (1) Except as provided in Section B (2) below, no person sh~ll cause, suffer, _~1 !ow, or permit the emission of particulate matter in any one ho~zr from any ~ ~ source in excess of the amount ~ shown in Table I for the allocated process weight. (2) The limitations established by Section B (I) shall hot require the reduction of particulate matter concentration, based on the source gas volume, below the commentration specified in Table 2 for such volume. The burden of #242-15 5.1 . eh~wTug the source gas volume, including ail factors ~ud methods deter~ulnE such volume, shall be on the person seeking to come within the provisO, one of this section. (3)''~ No person shall cause, suffer, allow, or permit the emission of particu- late matter from any Source in a concentration in excess of 0.30 grain per standard cubic foot of exhaust gases. Provisions of this subsection shall not apply to existing grey iron jobbing cupolas. For purposes of this regulation, a Jobbing cupola is defined as a cupola which has a s~le melting cycle no more than ten hours Lu any consecutive 2l, hours and no more than 50 hours in consecutive seven days. (a) All e~sting grey iron jobbLug cupolas shall be equipped with gas cleaning devices and so operated as to remove 85 percent by weight of all the particulate matter in the cupol~ discharge gases, or release not more than 0.~ grain of particulate matter per st~ds~d cubic foot of discharge gas~ whichever is more strident. (b) All gases~ vapors~ and gas entra~ed e£fhents from such cupolas shall be incinerated at a temperature not less th~n 1200~ Fahrenheit for a period of not less than 0.3 seconds. (c) Exceptions. A temporary operational breakdown or cleaning or air pollution equipment for any process are permitted as exceptions to the provisions of Regulation A?C 5 provided the owner or operator i~medi~tely advises the Director of the circumstances and outlines an acceptable corrective program. In any ~vent, no operation that may cause an immediate public health hazard can be deemed an exception from this regulation. (d) Any existing emission source which has particulate collection equipment with a collection efficiency of 99 percent by weight or any new emis- sion source which is installed with particulate collection equipment of 99.7 percent efficiency by~ we~Eht shall be considered as meeting the provisions of this regulation. #2&2-16 5.2 ~ny emission source located outside of the Minneapolis-St. Paul ~%ropolit~n Ar~ which h~ parti~_!~te collection equipment with a collection. efficiency of not less than 85 percent by weight, and is located not less than one-fourth mile from any residence or public roadway and the operation thereof does not create a suspended particulate concentration in the ambient air beyond the property lines of the source of emission which is above the ambient air quality standards shall be considered as meeting the provisions of this regulation.

In calculating the amount of particulate matter in stack gas~ the loading shall be adjusted to 12 pereent carbon dioxide in the stack gas. The carbon dioxide produced by bur~ing of any liquid or gaseous fu~l in the incinerator shall be excluded from the calculation to 12 percent carbon dioxide. Emissions shall be measured under maximum operation capacity or at any other burning rate wherein emission of ~a~%~¢~la~e m~tter is gre~ter. B. Restriction of Emissions of Particulate Matter from Incinerators. (L) No person shall cause or permit the emission of particulate matter from the stack or chimney of any incinerator in excess of the following: (a) Incinerators with a maw~mum refuse burning capacity of less than 200 pounds per hour, 0.~ grains of particulate matter per stand~rd dry cubic foot of exhaust gas. #2&2- 0 7.1 (b) Incinerators with a ms_ximum refuse burning capacity of 200 to 2000 pounds per hour, 0.2 grains of particulate matter per sts~dard dry cubic foot of exhaust gas. ~ (c) Incinerators with a ma~'mmum refuse bu~ing capac±t~'in excess of 2,000 pounds per hour, O.1 grains of particulate matter per standard dry cubic foot e~Z~must gas. (2) All new incLuerators and all existLug incinerators to be modified to meet the requirements of this regulation and which are to burn t~e ll~ lll,lV,V~ V1 waste as classified by the Incinerator Institut'e of America nust be equipped with auxiliary fuel burners of such capacity and design as to ass~zre a tempera- ture in the secondary combustion chamber of at least 1200°F. for a sufficient time to prevent objectionable odor emission. (3) No incinerator shall be used for the buring of refuse unless such in- cinerator is a multiple ch~nber incinerator. E~±stiug incineratbrs which are not multiple chamber incinerators may be altered, modified or rebuilt as may be necessary to meet this requirement. The Dirsctor may approve any other altera-- tion or modification to an existing incinerator if such be found by him to be equally effective for the prupose of air pollution control as a modification or alteration which would result in a multiple chamber incinerator. All new incinerators shall be multiple chamber incinerators, provided that the Director may approve any other kind of incinerator if he finds in advance of construction or installation that such other k~nd of incinerator is equally effective for purposes of air pollution control as an approved multiple chamber incinerator. Existing incinerators buring class II and class III waste which are not multiple chamber incinerators and do not otherwise meet the requirements of Section B(I) of this regulation shall be modified or rebuilt in compliance with this section in accordance with the schedule below. Existing incinerators burning class IV, V, or VI waste require the specific approval of the Dir~.tor.
