Review of the International Mechanical Code
Seven local amendments exist in Chapter 1 pertaining to regarding jurisdiction, liability, fee schedules and fee refund. Staff recommends continuing all existing local AMENDMENTS in Chapter 1.
Definition of “Commercial Cooking Appliance” was rewritten in an attempt to define commercial.

Footnote (A) was added and gives the requirements of Table 401.5.
Section 403.3.2.4 Section was added and states, “Where provided within a dwelling unit, controls for outdoor air ventilation systems shall include text or a symbol indicating the systems function.”
Section 403.3.2.5 Section was added and states, “exhaust equipment serving single dwelling units shall be listed and labeled to provide the minimum required air flow in accordance with ANSI/AMCA 210–ANCI/ASHRAE 51.”
Mr. Obermiller inquired of Section 403.2.5 and whether or not there should be a date of the ASHRAE or ANSI publication to reference. Mr. Taralson stated that there is a date listed in the reference standards section in the back of the code book.
Section 404.1, Item #2 Standby at an airflow rate of not less than .05 cfm per square foot of the floor area served. Staff’s opinion is that this is for the purpose of the inspection only. With unit heaters providing heat for the space, fans wound not running continually.
Discussion ensued regarding cfm and makeup air in parking garages.
Section 501.2 Added Section 505 requirements for domestic cooking operations, and Sections 506 through 509 for commercial cooking operations.
Section 502.4.1 “Hydrogen limit in rooms” was changed to “flammability limit in rooms”.
Section 502.5 Text was changed to “Ventilation of battery systems in cabinets”, and is regulated by the International Fire Code and vented in accordance with Section 502.4 of this code.
Sections 502.14 through Section 502.16.2.2 Sections pertain to motor vehicle operations, repair garage, and their ventilation requirements. Text has been re-organized.
Section 504 Text was added, “clothes dryer duct shall be sealed in accordance with Section 603.9”.
Section 504.1 Duct cannot be undiminished in size and must have an area of not less 12.5 square inches.

Text was added, "where dryer exhaust ducts are enclosed wall or ceiling cavities, such cavities shall allow the installation of the duct without deformation”.
Section 505 This section was added, and going back to the definitions, the code is trying to be clearer on the difference between domestic and commercial cooking ventilation requirements. This section is giving the requirements on domestic cooking appliances and the venting needed and the codes and standards which regulate them.
Section 505.4 Staff recommends continuing the existing local AMENDMENT which states only cfm in excess of 400 cfm needs to be made up. Change from Section 505.2 to Section 505.4.
Section 505.6. Language was changed to read, “in other than Group R occupancies, where domestic cooktops, ranges, and open-top broilers are used for domestic purposes, domestic cooking exhaust shall be provided”.
Section 506.5.2 Section added which states, “it is a manufactured piece of equipment installed in a grease exhaust duct system for the purpose of extracting grease particles and odors from the exhaust flow by means of series of filters”. There are 15 code regulations that must be followed. The exhaust termination can be a nuisance to the public due to an odor, PCU’s are designed to eliminate the odors.
Pollution control units have not yet been used in Fargo’s jurisdiction.

Mr. Obermiller stated that hoods that have 18 inches of perforated laminar flow air, should no longer require 40% to be made up with other equipment and suggested discontinuing the local AMENDMENT. Mr. Beaken stated that he agreed with Mr. Obermiller’s recommendation to discontinue the existing local AMENDMENT as the current hoods are designed operate for makeup air on their own. Mr. Obermiller stated that he would like to see a requirement for hoods to be tempered to at least 55 degrees Fahrenheit do to the climate and extremely cold makeup air that will be present at times.
Section 510.8.1 Section was added and states, “dust collection systems must have cleanouts every 20 feet”.
Section 601.5, Item #8 Item #8 was added and prohibits return air to be taken from an indoor swimming pool or its decks.

Review of Previously Covered Sections Requiring Further Review:
International Residential Code, Chapters 1-2, Presented by Bruce Taralson on September 6, 2018.
Minutes from September 6, 2018:
Section 202 A definition of GREENHOUSE has been added to recognize the unique environment of growing plants and that can be different than habitable spaces.
Mr. Fursteneau inquired if sunlight in a Greenhouse is assumed as natural light and asked Mr. Taralson how he would rule if a facility did not use natural light. Mr. Taralson stated that the code does not address whether the sun is actually out or not and it is the same with snow, the code addresses surfaces, but not whether a surface is covered with snow. Mr. Honzay inquired if it would be worth making a change so that the code stated a “lit” environment instead of a “sunlit” environment. Mr. Taralson stated that he would review the background of light and ventilation, and if there is not a normal environment of glass, the building would be considered a different environment.
Mr. Tarlason stated that he further researched greenhouses, however, he noted that there is not information in the light and ventilation requirements regarding greenhouses. He stated that there are some differences between mercantile greenhouses and assembly type greenhouses. Mr. Taralson furthered that all glass must comply with glass requirements and all plastic must comply with plastic requirements, however, he did not see an issue with leaving the verbiage of the code as is.
International Building Code, Chapters 11-15, Presented by Doug Desotel September 20, 2018.
Minutes from September 20, 2018:
Section 1206 Sound Transmission. This section was previously deleted from the 2015 International Building Code. The Inspections Department would like the Board to make the determination whether or not this section should be re-added to the 2018 International Building Code. Staff recommends removing the AMENDMENT deleting this section in its entirety.
Mr. Taralson stated that after review of the Gypsum manual, which provides data on sound testing, he found that most of the floor assemblies did comply, however, most wall assemblies did not. He furthered explained that buildings built out of steel seem to comply, but wood does not. Mr. Taralson stated that he believed that the previous Inspections Administrator removed this section as only some buildings meet the sound requirements and sound testing is not a required inspection. Mr. Taralson stated that he recommends continuing the existing local AMENDMENT deleting this section in its entirety.
The Board requested that this topic be tabled and further discussed before making a recommendation.
International Building Code, Errata, September 20, 2018.
Minutes from September 20, 2018:
Mr. Taralson stated that he will create a report on errata showing how changes were viewed in the past and how they can be viewed during the current hearing cycle. He furthered that most errata are numerical or spelling corrections. Mr. Erickson stated that an erratum does not change the intent of the code. Further discussion ensued regarding the number of edition printed and notations of errata in the code.
Mr. Taralson stated that the International Code Council does not provide anything in writing regarding the appropriate definition of errata. He furthered that errata is continually happening and fixing errors in code, but never changing the intent of the code.
Item 4 – Staff Reports. There were no staff reports at this time. Mr. Taralson reminded all in attendance that there is not a meeting on December 27, 2018.
Mr. Dietrich requested that Board members notify Gretchen Morlan of any scheduled vacations in order to ensure that a quorum is present at upcoming meetings.
