Fundamental principles. The Ministry of the Environment and Natural Resources issues this Regulation within the framework of compliance with and respect for the legal system of the country, the fundamental principles of good regulatory practices and based on the principles of transparency, due process, control of discretion, coherence, effectiveness and efficiency, as well as equity and impartiality, on which the processes of environmental administration are based with respect to all regulated entities. Article 4. Definitions. For the purposes of this Regulation, it is understood as: 1. Atmosphere: Gaseous layer that surrounds the earth. 2.

Twenty one (21) of its congeners are classified as highly toxic in small amounts. 17.Emission: Output of pollutants into the environment from a fixed source or mobile. 18. Bacharach Scale: It is a method used to measure opacity in one. Its operation consists of sending a certain amount of combustion gases to a paper filter through a certain number of pumps. The gray shade of the stain that occurs on the filter paper is compared to a scale of shades of gray with different numbers. The opacity scale determined in this way is between 0 and 9, ranging from white to black. 19.Ringelmann Scale : Range of indices used to determine by comparison, the degree of opacity caused by combustion fumes that are emitted into the atmosphere through a duct or chimney. Page 4 of _ Machine Translated by Google 20. Emission Source: Any activity , process or operation, carried out by human beings or with their intervention, capable of emitting pollutants into the air. 21.Fixed Source : Any structure, building, facility, equipment, installation or combinations of these that is located in one or more properties contiguous or adjacent, owned and operated by the same person that issues or can emit any pollutant. To differentiate between new and existing sources, the date of issue of this Regulation will be taken as a reference. This means that: a) Existing facilities are considered to be those that were in operation or in the final phase of installation prior to the date of issuance of the Regulation, including those projects that had completed their Environmental Impact Assessment process and obtained the corresponding license or permit. , prior to said date; b) Those projects or facilities installed or whose installation has been authorized after the indicated date are considered new. 22.Incineration: Combustion process of substances, residues or waste, in solid, liquid or gaseous state. 23. Incinerator: Equipment used in the controlled burning of waste or other combustible waste, whether liquid, solid or gas. 24.Hydrocarbons (HC): Gaseous, liquid or solid organic compounds made up of carbon and hydrogen. They are insoluble in water and are measured as hexane (C6H14) in parts per million. 25. Smoke: Visible mixture in the air of small particles and gases, generated by the combustion. 26. Immission: Transfer of pollutants from the atmosphere to a receiver. 27. Air Pollutant Emission Limit : Maximum emission concentration permissible amount of an air pollutant, discharged to the atmosphere through a chimney or duct. This limit has been established to protect the health and environment. 28. Particulate matter (Total Suspended Particles, PTS,): Divided solid and liquid material that may be dispersed in the air, coming from combustion processes, industrial activities or natural sources and whose aerodynamic diameter is less than 60 micrometers. 29.Ringelmann Method: Technique employed for measuring visible emissions, by using cards that have a comparative scale called Ringelmann scale. 30.Monitoring: Periodically or continuously scheduled process to collect samples and/or carry out measurements of one or several characteristics of the environment or emissions, generally, in order to assess compliance with specific regulatory requirements.

REQUIREMENTS AND TECHNICAL CRITERIA FOR THE DESIGN OF THE CHIMNEY Requirements and technical criteria for the selection of isokinetic sampling points demanded by the Secretary of State for the Environment and Natural Resources, and which must observe all the facilities that have a power generation process, boilers, ovens, incineration, combustion engines , steam and gas turbines, heating system and others. The fundamental objective is to achieve that in the sampling sites in a chimney a uniformity of the flow can be obtained, Page 39 of _ Machine Translated by Google in such a way that the lines of movement of the fluid are parallel to the walls of the duct. 1.- The chimneys and gas outlet ducts and particulate matter from combustion processes, for energy generation, ovens, boilers, distillation and others, must have a minimum height of 15 meters or according to the height of a good engineering design (hBDT), Buildings located in the immediate vicinity of a chimney influence the development of the plume differently according to the ratio of its height to its width. The height of a good technical design (hBDT) is then defined, hBDT = 2.5 Hedif Hedif , yes L ÿ Hedif = is the height of the building and L= is the smallest dimension between: the transverse width projected in the direction of the wind and the height. Nearby buildings are considered to modify the plume development if the stack height is less than hBDT. In this case, it will be necessary to consider the effects of removal, and the dimensions of these buildings must be specified, as well as their location on the same map where the chimneys were located. 2.-For the taking of samples and analysis, it is required that the installation has a platform, whose connections to measure and take samples are at a distance of 1.60 meters in length and 80 centimeters in width where the protection and security guards will be placed or another similar fixed construction with easy access, on which two or three people can easily operate at the planned sampling points, with safety rails. The platform must completely surround the chimney with a width of 80 centimeters where the protection and safety guards will be placed. 3.-The measurements and sampling in chimneys will be carried out at a point such that the distance to any gas flow disturbance (elbow, connection, change of section, direct intake, etc.) is at least eight times the internal diameter of the chimney. nearest downstream disturbance. This is applicable for circular chimneys 4.- For rectangular and square section chimney, its equivalent diameter will be determined using the mathematical equation that the equivalent diameter is equal to the product of the length by the width divided by the sum of the length plus the width. Page 40 of _ Machine Translated by Google 5.-The circular holes are 4 inches that are made in the chimneys to facilitate the introduction of the necessary elements for the measurements and sampling, they will be equipped with a cap or nipple or section of 4-inch threaded galvanized iron pipe that Allows coupling at the end to place a male or female plug that prevents the escape of gases when the nipples are not being used. 6.- The number of holes and corresponding connections will be two in circular chimneys and located according to perpendicular diameters, in the case of rectangular and square chimneys these numbers will be three, arranged on the smaller side and at the midpoints of the segments that result from dividing the corresponding internal lateral distance into three equal parts. In chimneys greater than 2.50 meters in outside diameter, 4 holes must be drilled at 90 degrees, at the same height and distributed according to the construction of the platform. 7.- If there is a static electrical charge in the chimney system, it is advisable to ground it electrically. The site must have electricity services at 110 volts, light if it is necessary to carry out night sampling. 8.- The ladder to climb to the platform must be equipped with a landing every 9 meters in height 9.- The platform must be equipped with a pulley that facilitates the climbing of the equipment with a rope 10.- The company must supply the data of each chimney: Diameter, distance from the hole to the gas outlet and from the hole down to the previous disturbance, as well as % humidity, % CO2 and O2 of combustion gases , plant layout , fuel data and stack diagram. 11.-The company must install the added control systems for the collection of particulate matter and gas washing according to the necessary operating systems in its facilities (among these added control systems are the famous sleeve filter (bag house, electrostatic filter, cyclones, venturi etc.) The objective of these systems is to minimize the impacts caused by them.
