Purpose and Reason :
RISBC-3 State Plumbing Code sets forth the requirements for plumbing in Rhode Island. Rhode Island Building Codes are amendments of the International Building Codes which we use as our model. The Building Standards Committee modifies parts of the Codes to adhere to our State and the elements of our State. The State Building Code Standards Committee has reviewed this regulation and proposes the following non-technical amendments as described below:
· All references to International Plumbing Code (“IPC”) 2012, have been changed to the 2015 edition. Some IPC section numbers have been amended to conform to IPC 2015.
· Throughout the regulation: updated internal cross-references with new RICR citations and references to the 2019 version for all Parts in Title 510 being amended this year.
· § 3.2(A)(4) & (5) and (B) because this information is not regulatory content and could change. The dates of distribution of updated codes cannot be known in the drafting process so this information will be provided on the State Building Code Standards Committee’s website. The date of adoption by the Legislative Regulation Committee will be recorded in the Concise Explanatory Statement.
· Chapter 6: Water Supply and Distribution, Section 602.3.4. Added exception of construction or repair, the individual water supply system shall be purged of deleterious matter and disinfected in accordance with 610.
· Chapter 6: Water Supply and Distribution, deleted Sections 703.6 and 705.11.2. The RI amendment is deleted as the model code inclusion makes the amendment no longer necessary. No Code Changes or additional requirements result.
