Amendments to the federal code related to onshore gas transmission pipelines include: (1) integrity management requirements, focused on the actions an operator must take to reconfirm the maximum allowable operating pressure of previously untested natural gas transmission pipelines and pipelines lacking certain material or operational records; (2) the periodic assessment of pipelines in populated areas not designated as “high consequence areas;” (3) the reporting of exceedances of maximum allowable operating pressure; (4) the consideration of seismicity as a risk factor in integrity management; (5) safety features on in-line inspection launchers and receivers; (6) a 6-month grace period for 7-calendar-year integrity management reassessment intervals; and (7) related recordkeeping provisions.
Amendments to the federal code related to underground natural gas storage facilities include: (1) incorporation by reference of American Petroleum Institute (API) Recommended Practices; (2) requirements to implement integrity management programs; (3) risk management for salt caverns; (4) narrowing the scope of reportable events and changes at facilities; (5) revising the definition of an "underground natural gas storage facility; and (6) changing the name of the reporting portal.
Other safety related updates to ch. PSC 135, include: (1) renumbering sections of ch.PSC 135 to coincide with the federal code; (2) clarifying the required interval for utility leak detection surveys; (3) removing sections that refer to old technology no longer in use, including the Bessemer process and the grandfathered use of cast iron pipe; (4) prohibiting new low-pressure distribution systems; and (5) requiring gas operators to file construction standards prior to construction. 4. Detailed explanation of statutory authority for the rule (including the statutory citation and language):
Section 196.02(1) authorizes the commission to do all things necessary and convenient to its jurisdiction. Section 196.02(3) grants the commission specific authority to promulgate rules. Section 196.745, authorizes the commission to issue orders and rules requiring the safe construction and operation of gas facilities in this state. Section 227.11 authorizes agencies to promulgate administrative rules. Under an agreement with the PHMSA, Office of Pipeline Safety, the commission agrees to adopt those parts of the federal code that apply to pipeline safety.
5. Estimate of amount of time that state employees will spend developing the rule and of other resources necessary to develop the rule:
The commission estimates that fewer than 100 hours of employee time will be required to develop the rules.
6. List with description of all entities that may be affected by the proposed rule:
Every intrastate gas pipeline operator that operates gas transmission or distribution facilities in this state will be impacted by the rule.
7. Summary and preliminary comparison with any existing or proposed federal regulation that is intended to address the activities to be regulated by the proposed rule:
This rulemaking adopts updates to the federal code since the last revision to ch. PSC 135 took effect. Therefore, the changes to ch. PSC 135 proposed in this rulemaking will conform state regulation with respect to pipeline safety, to existing federal regulation. 8. Anticipated economic impact of implementing the rule (note if the rule is likely to have a significant economic impact on small businesses):
This rule will result in no economic impact because pipeline operators are required, under federal law, to follow the federal regulations. The changes to ch. PSC 135 proposed in this rulemaking will authorize the commission to enforce these regulations in Wisconsin. Without this rulemaking, commission authority to administer the federal pipeline safely program in Wisconsin will likely revert to PHMSA, and federal funding for the commission’s pipeline safely program will likely be cancelled. Other changes to ch. PSC 135 proposed in this rulemaking will also result in no economic impact because these changes represent updates to conform the rule to current technology and safety practices already accepted by the industry.
