AND RULEMAKING UPDATES
Current Rulemakings in Process
• Miscellaneous Rulemaking • EFV Expansion beyond Single Family Residences• Standards Update Rule • Plastic Piping System Rulemaking
Current Rulemakings in Process
• Miscellaneous Rulemaking (Final Stage)– requirements for qualifying plastic pipe joiners
• EFV Expansion beyond Single Family Residences (Final Stage)– Rule will propose to require EFVs for: • branched service lines serving more than one single
family residence • multi-family residential dwellings • commercial buildings
Current Rulemakings in Process
• Standards Update Rule (Based on proposal in NPRM)– Would impact 22 of the 60+ standards currently
incorporated by reference (IBR)– ASTM D2513-09a would be incorporated through §192.7 for
PE with the exception of Section 4.2 pertaining to rework – ASTM D2513-87 (for 192.63 marking only) and ASTM D2513-
99 (except section 4.2) would continue to be IBR for non-PE plastics
– Would also add explicit paragraph in 192.59 (materials) to say “Rework and/or regrind material is not allowed in plastic pipe used under this part.”
Plastic Piping System Rulemaking
In Draft• Incorporation of 15+ new or updated standards• Category 1 only for mechanical fittings• Tracking and Traceability• Increased Design Factor for PE (0.32 to 0.40)• PA-11: revise current limitations (up to 250 psi and
6”)
Plastic Piping System Rulemaking (cont.)
• PA-12: incorporate with limitations (up to 250 psi and 6”)
• Code revisions for risers based on best practices – both mains and services
• Additional revisions to code for installation of plastic pipe based on current best practices (i.e. use of proper backfill, trenchless installation best practices, etc.)
Advisory Bulletins
