FINAL

ORDER

4455 Delaware Regulations Governing a Detailed Plumbing Code

NATURE OF THE PROCEEDINGS:

Delaware Health and Social Services (“DHSS”) initiated proceedings to adopt the State of Delaware Regulations Governing a Detailed Plumbing Code (4455). The DHSS proceedings to adopt regulations were initiated pursuant to 29 Delaware Code Chapter 101 and authority as prescribed by 16 Delaware Code, §7903.

On May 1, 2015 (Volume 18, Issue 11), DHSS published in the Delaware Register of Regulations its notice of proposed regulations, pursuant to 29 Delaware Code Section 10115. It requested that written materials and suggestions from the public concerning the proposed regulations be delivered to DHSS by June 5, 2015, or be presented at a public hearing on May 29, 2015, after which time the DHSS would review information, factual evidence and public comment to the said proposed regulations.

Written comments were received during the public comment period and evaluated. The results of that evaluation are summarized in the accompanying “Summary of Evidence.”

SUMMARY OF EVIDENCE

In accordance with Delaware Law, public notices regarding proposed Department of Health and Social Services (DHSS) State of Delaware Regulations Governing a Detailed Plumbing Code were published in the Delaware State News, the News Journal and the Delaware Register of Regulations.

Comments from the International Code Council:

My name is Bryan Soukup and I am the Regional Governmental Relations Manager for the Mid-Atlantic States at the International Code Council (ICC). Please allow this letter to serve as public comment in support of a final approval relative to the proposal to update the 2012 Delaware Plumbing Code to the published 2015 Delaware Plumbing Code.

The ICC is a member-focused association dedicated to helping the building safety community and the construction industry provide safe and sustainable construction through the development of codes and standards used in the design, build, and compliance process. Most U.S. states and communities, Federal agencies, and many global markets choose the International Codes to set the standards for regulating construction, fire prevention, and energy conservation in the built environment.

The International Plumbing Code (IPC) along with 15 other International Codes (I-Codes) are updated and revised every three years through a national consensus process that strikes a balance between the latest technology, new building products, installation techniques, economics, and cost while incorporating the most recent advances in public and first responder safety. It is an open, inclusive process that encourages input from all individuals and groups, and allows ICC Governmental Members1 to determine the final code provisions.

The I-Codes are correlated to work together without conflicts so as to eliminate confusion in building design, inconsistent code enforcement, or differing interpretation among different jurisdictions. Jurisdictions that utilize the most current edition of the I-Codes thereby ensure the highest standards for safety, energy efficiency, sustainability, economic incentive, and long-term resiliency of their built environment.

I would like to commend the State of Delaware for its consistently outstanding work reviewing and now proposing to update the Delaware Plumbing Code that is based on the 2015 IPC. The proposed amendments and update of this code, while incorporating amendments that reflect the unique character and needs of Delaware, will ensure that the Delaware Plumbing rules remain technically viable relative to drinking water and plumbing fixtures, allow for economic investment in building construction, and provide for the greatest safety of the public and emergency responders, while embracing new technology and building practices.

Some of the significant changes included in the 2015 IPC include:

Technical assistance and training from ICC is always available to groups including, but not limited to: Delaware Design Professionals, Delaware Plans Examiners, the Delaware State Board of Plumbing & HVACR and other entities. They will have access to ICC training programs and materials, product Evaluation Reports, certification programs, and ICC technical staff, who will assist with code opinions and interpretations based on the IPC.

Thank you for the opportunity to submit these comments. The ICC is honored to partner with the State of Delaware in support of the adoption and administration of the Delaware Plumbing Code that is based on the 2015 IPC and we look forward to continuing to serve your needs for many more years.

Please feel free to contact me via email or phone (information noted below) if you have any questions, concerns, or comments relative to the Plumbing Code adoption or anything else ICC-related.

Plumbing Program Response:

Thank you for your support in the promulgation of these regulations.

The public comment period was open from May 1, 2015 through June 5, 2015. One comment was received on the proposed regulations during the public comment period but no changes have been made to the proposed regulations.

Verifying documents are attached to the Hearing Officer’s record. The regulation has been approved by the Delaware Attorney General’s office and the Cabinet Secretary of DHSS.

FINDINGS OF FACT:

No changes were made to the proposed regulations based on the comments received. The Department finds that the proposed regulations, as set forth in the attached copy should be adopted in the best interest of the general public of the State of Delaware.

THEREFORE, IT IS ORDERED, that the proposed State of Delaware Regulations Governing a Detailed Plumbing Code (4455) is adopted and shall become effective August 11, 2015, after publication of the final regulation in the Delaware Register of Regulations.

Rita M. Landgraf, Secretary
