SPS 340.11 Note Note: A proposed alteration for an existing system may necessitate modifying other components of the system in order to make the proposed alteration comply with this chapter — and some alterations may necessitate modifying other features of a building, such as an automatic fire sprinkler system, that must comply with requirements in chapters SPS 361 to 366, the Wisconsin Commercial Building Code.
SPS 340.11(6) (6)Differing rules.

SPS 340.11(6)(c) (c) Where different sections of this chapter specify conflicting requirements, the most restrictive requirement, as determined by the department, shall govern, except as provided in pars. (a) and (b).
SPS 340.11(7) (7)Interpretations. Under s. 101.02 (1), Stats., the department reserves the right to interpret the requirements in this chapter and in all adopted codes and standards.
SPS 340.11 Note Note: Section 101.02 (1) of the Statutes reads as follows: “The department shall adopt reasonable and proper rules and regulations relative to the exercise of its powers and authorities and proper rules to govern its proceedings and to regulate the mode and manner of all investigations and hearings."
SPS 340.11(8) (8)First class cities. All references in this chapter to submitting documentation to or having inspections performed by a first class city apply only to gas systems within that city.
SPS 340.11 Note Note: The scope of some of the standards that are adopted by reference in subchapter IV are broader than the scope of this chapter. For example, NFPA® 52 contains requirements for liquefied natural gas and compressed natural gas engine fuel systems on vehicles. Any requirements which are beyond the scope of this chapter cannot be enforced under this chapter, but may be adopted by local ordinances. Those ordinances may be adopted under statutory authority that is separate from the Department's statutory authority.
SPS 340.11 Note Note: Chapters SPS 361 to 366 contain the Department's requirements for fuel gas systems that are beyond the scope of this chapter and within public buildings and places of employment. Chapters SPS 320 to 325 contain requirements for fuel gas systems that are beyond the scope of this chapter and for one- and 2-family dwellings.
SPS 340.11 Note Note: See chapter SPS 310 for the Department's requirements relating to storage, dispensing, handling and use of flammable, combustible or hazardous liquids. Those liquids are defined in that chapter in a manner which differentiates them from the substances regulated by this chapter. See chapter SPS 314 for requirements relating to fire prevention. See chapter SPS 341 for requirements relating to pressure vessels for gaseous or liquid hydrogen that is not used to fuel heating appliances, industrial processes or engines. See chapter SPS 345 for requirements relating to gasses that are used in mechanical refrigeration systems.
