PSC 134.23 Pressure variation.

(1) Every utility supplying gas shall file with the commission a standard service pressure by service areas. The service pressure shall be of such a value that the maximum pressure at any outlet as specified below shall not be greater than 12 inches of water column except for customers utilizing high-pressure service.

(2) For customers receiving standard service pressure, the gas pressure at the outlet of the utility’s service meters shall meet the following requirements:

(a) At no outlet in the service area shall it ever be greater than one and one-fourth of the standard service pressure nor greater than 12 inches of water nor ever be less than one-half of the standard service pressure nor less than 4 inches of water.

(b) At any single outlet it shall never be greater than twice the actual minimum at the same outlet.

(c) At any one outlet the normal variation of pressure shall not be greater than the following:

(3) For customers utilizing gas at high pressure, a service pressure shall be agreed upon by the utility and the customer, and the maximum pressure variation shall not exceed 15% of the agreed pressure unless the commission shall authorize a greater variation.

(4) No utility shall furnish gas to any customer at pressures higher than its filed standard service pressure until it has filed with the commission acceptable service rules governing high-pressure service to customers desiring to utilize gas at pressures higher than standard service pressure. Such service rules shall provide that the utility will make high-pressure service available to its customers upon request whenever high pressure gas is available at the customer’s premises or may be made available in accordance with the utility’s filed extension rules, and when such high pressure is required for proper operation of the customer’s present or proposed utilization equipment.

  "currentnessBasis": "Official publisher states the entire administrative code is current and updated on the first day of each month.",
  "legalScope": "This completeness-verified corpus contains every current section of Wisconsin Administrative Code Chapters PSC 133, 134, and 135, plus complete Wis. Stat. §§ 196.745 and 182.0175. Chapter PSC 135 is the dedicated gas-safety chapter. Chapters PSC 133 and 134 are included because the Wisconsin PSC identifies all three chapters as requirements used in pipeline-safety inspections; they also contain broader construction, siting, utility-service, billing, metering, and customer provisions.",
  "applicabilityCaveat": "Applicability depends on Wisconsin PSC jurisdiction, operator and facility type, intrastate or interstate status, gas-public-utility status, project thresholds, activity, exemptions, waivers, Commission orders, federal preemption, and the specific provision. Wis. Stat. § 196.745 excludes propane distribution systems from the PSC pipeline-safety program, while the one-call law reaches transmission facilities beyond natural-gas pipelines.",
  "incorporationCaveat": "Chapter PSC 135 adopts and supplements federal minimum pipeline-safety standards, principally 49 CFR Parts 191, 192, 193, and 199. The source also cites statutes, administrative rules, Commission forms and orders, and private technical standards.

  "rightsCaveat": "Official Wisconsin Legislature and Public Service Commission text is preserved with attribution and source hashes. Public availability does not establish a blanket license for site presentation, agency marks, annotations, forms, or incorporated federal and privately authored standards; downstream redistribution requires separate rights review.",
