Title of Rule: Adoption of chapters 51-56 and 51-57 WAC (adoption and amendment of the 2000 Edition of the Uniform Plumbing Code and Plumbing Code Standards). Repeal of chapters 51-46 and 51-47 WAC (adoption and amendment of the 1997 Edition of the Uniform Plumbing Code and Plumbing Code Standards).

Purpose: To consider whether to adopt, or amend and adopt, the 2000 Edition of the Uniform Plumbing Code and Plumbing Code Standards, published by the International Association of Plumbing and Mechanical Officials, and repeal the 1997 edition of these codes.

Statutory Authority for Adoption: RCW 19.27.031 and 19.27.074.

Statute Being Implemented: Chapters 19.27 and 34.05 RCW.

Summary: The proposed rules include adoption of the 2000 Edition of the Uniform Plumbing Code and Standards, with amendments (including Appendix I, Installation Standards), and repeal of the 1997 Edition. Amendments providing greater safety and flexibility than the published version including medical gas systems, venting of fixtures, storm drainage, cross connection control, plumbing materials, and existing state amendments carried forward to the 2000 Edition.

Reasons Supporting Proposal: RCW 19.27.031 and 19.27.074.

Name of Agency Personnel Responsible for Drafting and Implementation: Al Rhoades, P.O. Box 48300, Olympia, WA 98504-8300, (360) 586-8999; and Enforcement: Local jurisdictions.

Name of Proponent: Washington State Building Code Council, governmental.

Agency Comments or Recommendations, if any, as to Statutory Language, Implementation, Enforcement, and Fiscal Matters: The council is seeking comments on the issues proposed in the rules shown below.

Rule is not necessitated by federal law, federal or state court decision.

Explanation of Rule, its Purpose, and Anticipated Effects: The proposed rule will adopt by reference and amend the 2000 Edition of the Uniform Plumbing Code and Uniform Plumbing Code Standards (UPC), published by the International Association of Plumbing and Mechanical Officials. The purpose is to replace the 1997 UPC (chapters 51-46 and 51-47 WAC), which will then be repealed, and assign the 1997 UPC new Washington Administrative Code (WAC) numbers (chapters 51-56 and 51-57 WAC). The 2000 UPC will be amended to provide greater safety and flexibility than the published version for its application in Washington state.

     Regulatory Review: In compliance with Executive Order 97-02, regulatory improvement, the following criteria for regulatory review will be considered at the time of final adoption of the rule.

     1. Need. This rule is necessary to comply with the requirements of RCW 19.27.074. The council must regularly review updated versions of the Uniform Plumbing Code, and amend and adopt as deemed appropriate by the council. An updated, 2000 version of the Uniform Plumbing Code has been published. The purpose and objective of this review, as given in RCW 19.27.020, is to promote the health, safety and welfare of the occupants or users of buildings; to require minimum construction standards for the state of Washington; to permit the use of modern technical methods; to eliminate restrictive, obsolete, conflicting, duplicating and unnecessary regulations; and to provide standards to make buildings accessible to and usable by physically disabled persons. The technical advisory groups appointed by the council have identified rules that are obsolete, duplicative or ambiguous, and have proposed amendments and revisions.

     2. Effectiveness and Efficiency. The mission of the council is to adopt building codes for uniform application throughout the state. In the course of the regular rule review, the council examined regulatory alternatives and new technologies. The council has identified where alternatives can be used effectively and efficiently. The council efficiently achieves uniform state building codes by serving as the central administrative agency for state-wide adoption of building codes.

     3. Clarity. To enhance clarity, only those subsections with a state amendment will be filed under the main section number. The balance of the main section will remain as written in the national uniform code, as adopted by reference, unless otherwise noted.

     4. Intent and Statutory Authority. The proposed rule is consistent with the legislative intent of the statute chapter 19.27 RCW. The statute gives the council sufficient authority to maintain the state building code, and to amend and adopt new editions of the Uniform Plumbing Code. The Uniform Plumbing Code is published every three years.

     5. Coordination. The council rule-making process includes participation by national, state, and local building, fire, mechanical and plumbing officials, as well as state agency representatives for the Departments of Social and Health Services, Health, Labor and Industries, and the State Fire Marshal. The council actively seeks participation from other state agencies to assure that duplication and inconsistency is eliminated.

     6. Cost. The council appointed technical advisory groups and an Economic and Regulatory Assessment Committee to examine the costs and benefits associated with the revisions to the building codes.

     7. Fairness. The state amendments to the Uniform Plumbing Code proposed by the council are intended to mitigate disproportionate impact on the regulated community. The council is made up of representatives from the regulated community, as well as public and regulatory officials. In addition, the council enlisted the assistance of technical advisory groups, made up of the individuals, organizations and businesses impacted by the building codes, to review code changes and proposals.

Proposal Changes the Following Existing Rules: The proposal will replace the 1997 UPC with the updated 2000 UPC which contains national changes made to the code. Proposed amendments provide for specific application of the code in Washington state. The amendments added to the 2000 UPC are as follows:

     Chapter 51-56 WAC:

     1. Sections 001, 002, 007, 008: These sections maintain existing state-wide amendments, correcting section references and dates.

     2. Section 003: This change updates the adopting language, allows conformance with chapter 19.27 RCW and maintains the intent of that law. This section mandates that Chapters 11 and 12 are not adopted. It also mandates that the portions of the code addressing venting and combustion air of fuel fired appliances and those portions addressing building sewers not be adopted.

     3. Section 101.4.1.4: Maintain existing state amendment, correcting section references. This section is not adopted. This requirement is in direct conflict with chapter 19.27 RCW, which sets specific code precedent.

     4. Section 102.4: Add a subsection outlining an appeal process. The Plumbing Code does not currently contain an appeals process. This amendment brings the code into conformance with the other model codes.

     5. Section 103.1.3: Maintain existing state amendment.

     6. Section 205: Revise the definition of Certified Backflow Assembly Tester for consistency with Department of Health regulations.

     7. Section 208: Revise the definition of Flammable Vapor or Fumes for consistency with the Fire Code.

     8. Section 218: Maintain existing state amendment.

     9. Section 301.1.1: Maintain existing state amendment.

     10. Section 301.1.3: Maintain existing state amendment.

     11. Section 311.4: Maintain existing state amendment, correcting section references. This section is also amended to include a reference allowing the use of horizontal wet venting per Appendix L.

     12. Section 313.6: Maintain existing state amendment, correcting section references.

     13. Section 313.7: Maintain existing language.

     14. Section 316.1.6: Maintain existing state amendment.

     15. Section 402: Maintain existing state amendment, with updated references.

     16. Section 412.2: Maintain existing state amendment.

     17. Section 413.0: Maintain existing state amendment.

     18. Section 501.0: This section is modified to maintain existing state amendment language.

     19. Section 502: This section is amended to delete definitions for which the Mechanical Code takes precedence.

     20. Section 505.0: Maintain existing state amendments. The Washington State Department of Labor and Industries has jurisdiction over hot water boilers.

     21. Section 506.2: Remove reference to hot water boilers. The Washington State Department of Labor and Industries has jurisdiction over hot water boilers.

     22. Section 507: Maintain current state amendment. The Mechanical Code takes precedence over combustion air issues.

     23. Section 509.0: Maintain existing state amendment.

     24. Sections 512 through 525: Maintain existing state amendment. These sections cover the venting requirements for water heaters. The Mechanical Code takes precedence over these sections and therefore they are being deleted.

     25. Sections 603.0: This amendment maintains the existing language and adds a reference to Washington State Department of Health requirements for backflow devices and assemblies.

     26. Section 603.3.3: This amendment is proposed to clarify existing requirements for annual testing of backflow assemblies. This change could be perceived to add enforcement cost if the requirements of this section have not been previously carried out.

     27. Section 603.4.6.1: Carries forward the existing state amendment and allows for a spill proof pressure vacuum breaker if approved by the local authority.

     28. Section 603.4.13: Retain the existing language in the 1997 UPC.

     29. Section 603.4.18.1: This amendment specifies the type of residential sprinkler system exempted under this section.

     30. Section 604.1: This section has been amended to clarify the allowable use of PEX.

     31. Section 604.13: Maintain the current state amendment.

     32. Section 608.5: Maintain the current state amendment.

     33. Section 610.4: This change maintains an existing state-wide amendment and corrects section references.

     34. Section 701.1.2: This change corrects section references due to another proposal to move Chapter 15 to Appendix M.

     35. Section 704.3: Maintain the current state amendment. This change eliminates conflict with Washington State Department of Health requirements.

     36. Section 710.3: Maintain the current state amendment.

     37. Part II - Building Sewers, Sections 713 - 723 and associated Tables: Maintain current state amendment. The Washington State Department of Health has jurisdiction over building sewer requirements.

     38. Section 810.4: Maintain current state amendment. The term "beehive" was felt to be proprietary.

     39. Section 903.1.2: This change corrects section references due to another proposal to move Chapter 15 to Appendix M.

     40. Section 1302: This change maintains an existing state amendment.

     41. Sections 1309 through 1315: These changes maintain existing state amendments and provide updated section references.

     42. Chapter 14: Delete the term "Mandatory" from the reference standards.

     43. Chapter 15: This proposal would move the existing Chapter 15, Firestop Protection for DWV and Stormwater Applications, to Appendix M, and substitute the current Appendix M, Storm Drainage (UPC Chapter 11), for Chapter 15.

     44. Appendix M: See 43, above.

     Chapter 51-47 WAC: Sections 51-47-001, 51-47-002, 51-47-003, 51-47-007 and 51-47-008: These sections maintain existing state-wide amendments correcting section references and dates.

     IS 7-90 Section 604.1 and IS 8-95 Section 604.1. This proposal would allow PVC to terminate inside a building.

A small business economic impact statement has been prepared under chapter 19.85 RCW.

Small Business Economic Impact Statement

     The State Building Code Council is proposing to adopt amendments to chapter 51-56 WAC, the 2000 Uniform Plumbing Code published by the International Association of Plumbing and Mechanical Officials. The council appoints Technical Advisory Groups (TAGs) to conduct a comprehensive review of proposed code amendments. The participants on the Plumbing Code TAG represent building trades (plumbers), building officials, model code organizations, homebuilders, mechanical contractors, and state agencies. The Economic and Regulatory Assessment Committee consists of council members as specified in SBCC bylaws.

     Proposed amendments to WAC 51-56-1500 Storm drainage, have been identified by the TAG and the Economic Committee as having a potential cost impact on businesses required to comply with the rule.

     Section 1500 Storm drainage is currently adopted as an appendix chapter, where the local authority having jurisdiction has the option to enforce the requirements. The proposed rule adopts the section for enforcement statewide. The appendix chapter is currently used as a design guide, and design requirements for roof drainage are standard practice. Rainfall rates are given in ranges, with local conditions to be determined by the authority having jurisdiction. Other requirements include place of drainage disposal, left open to the authority having jurisdiction; acceptable materials for rainwater piping; and subsoil drains, with local option to require an electric sump. Further analysis is necessary to determine added costs of compliance with this section.

A copy of the statement may be obtained by writing to Tim Nogler, Managing Director, Washington State Building Code Council, P.O. Box 48300, Olympia, WA 98504-8300, phone (360) 586-0486, fax (360) 586-5880.

RCW 34.05.328 does not apply to this rule adoption. The State Building Code Council is not listed in this section as one of the agencies required to comply with this regulation.

Hearing Location: Spokane City Council Chambers, West 808 Spokane Falls Boulevard, Spokane, WA, on September 15, 2000, at 10:00 a.m.; and at the Radisson Hotel, 17101 International Boulevard, SeaTac, WA, on October 13, 2000, at 10:00 a.m.

1508.2.1 Water Test
. After piping has been installed, the water test shall be applied to the drainage system, either in its entirety or in sections. If applied to the entire system, all openings in the piping shall be tightly closed except for the highest opening, and the system shall be filled with water to the point of overflow. If the system is tested in sections, each opening shall be tightly plugged except for the highest opening of the section under test, and each section shall be filled with water, but no section shall be tested with less than a ten (10) foot (3048 mm) head of water. In testing successive sections, at least the upper ten (10) foot (3048 mm) of the next preceding section shall be tested so that no joint of pipe in the building (except the uppermost ten (10) foot (3048 mm) of a roof drainage system, which shall be filled with water to the flood level of the uppermost roof drain) shall have been submitted to a test of less than a ten (10) foot (3048 mm) head of water. The water shall be kept in the system or in the portion under test for at least fifteen (15) minutes before inspection starts; the system shall then be tight at all points.


1508.2.2 Air Test
. The air test shall be made by attaching an air compressor testing apparatus to any suitable opening after closing all other inlets and outlets to the system, forcing air into the system until there is a uniform gage pressure of five (5) psi (34.5 kPa) or sufficient to balance a column of mercury ten (10) inches (254 mm) in height. This pressure shall be held without introduction of additional air for a period of at least fifteen (15) minutes.


1508.2.3 Exceptions. When circumstances exist that make air and water tests, described in Sections 1508.2.1 and 1508.2.2 above, impractical, and for minor maintenance, repairs and installations, the administrative authority may perform the inspection as considered advisable by said authority to assure that the work has been in accordance with provisions of this code.
