Notice of Proposed Rule
DAR File No.: 42744
Filed: 03/30/2018 11:01:55 AM
Purpose of the rule or reason for the change:
This change updates the list of authorizing statutes, fixes typos, and introduces a definition and a new section in response to comments from the Administrative Rules Review Committee.
Summary of the rule or change:
Nonsubstantive changes: 1) updated the list of authorizing statutes to include Subsection 26-1-30(9) and Section 26-7-1; 2) added the inches equivalent for signage requirements in Subsection R392-302-38(2)(b); 3) added a footnote to Table 6 reflecting the current language in Subsection R392-302-27(1)(b)(i); 4) fixed the numbering in Section R392-302-21; 5) capitalized "department" when referring to the Utah Department of Health; 6) fixed typo in Subsection R392-302-39(3)(c) to require rules lettering to be 0.5 inches tall instead of 1.5 inches; and 7) added a definition of "Instructional Pool". Substantial revision to the Special Purpose Pool section. This has been divided into separate sections for each type of special purpose pool. A new section is added for Instructional Pools. Changes made throughout the rule to reflect the new section numbers. Exemption to this rule given to instructional pools for three years. During this time, the Utah Department of Health (Department) will investigate the public health-related experiences and science of instructional pools operating with the exemption. Requires pools operating under this exemption to post signage and to obtain parent's acknowledgement.
Statutory or constitutional authorization for this rule:
- Section 26-1-5
- Subsection 26-1-30(23)
- Section 26-15-2
- Subsection 26-1-30(9)
- Section 26-7-1
Anticipated cost or savings to:
the state budget:
There are anticipated costs to the state budget of $330/year due to laboratory costs for testing of total coliform and plate counts.
This rule change will affect new construction of a pool if it meets the requirements to be an instructional pool. This rule change does not require construction or operational changes to existing facilities. A local government building an instructional pool may have an approximate savings of 80% to 90% of the construction costs as compared to meeting the requirements of the current rule. There may be ongoing savings in operating costs due to the proposed exemptions. The Department is unable to estimate this benefit due to the wide range of possible options involved (size, features, types of disinfectant, plumbing, etc.).
There are an estimated 11 swim school or swim instruction businesses from NAICS 611620, 611710, and 812199. There are an estimated 61 small businesses affected by this rule from NAICS 541330, 561790, 541690, 425120, 238992, 238991, and 236220, but an inestimable number from NAICS 713990, 713940, 531311, and 721110 as these businesses may or may not have swimming pools, and there is no reasonable method of determining such. In FY17 there were permitted 3,063 facilities, but the data is not available to determine which of these are small or non-small businesses. This rule change will affect new construction of a pool if it meets the requirements to be an instructional pool. This rule change does not require construction or operational changes to existing facilities. A small business building an instructional pool may have an approximate savings of 80% to 90% of the construction costs as compared to meeting the requirements of the current rule. There may be ongoing savings in operating costs due to the proposed exemptions. The Department is unable to estimate this benefit due to the wide range of possible options involved (size, features, types of disinfectant, plumbing, etc.).
persons other than small businesses, businesses, or local governmental entities:
No one specific person will be affected by this rule change.
Compliance costs for affected persons:
Affected persons for the state is the Department. For local governments it is any municipality or county with a public pool; 13 local health departments. For small businesses it is 11 swim schools; an inestimable number of businesses and facilities with pools, or provide services to these facilities and pools. For other persons there are none identified.
Comments by the department head on the fiscal impact the rule may have on businesses:
There are 11 swim schools and an estimated 62 small businesses that may be affected by this rule. The amendments will affect new construction of an instructional pool with an potential approximate savings of 80% to 90%. However, the Department is unable to estimate this benefit due to the wide range of possible options in said construction. After conducting a thorough analysis, it is determined that businesses will see a fiscal benefit from this amendment but due to the wide range of construction options, the benefit is inestimable.

This rule change does not require construction or operational changes to existing facilities.
A non-small business building an instructional pool may have a savings of 80% to 90% of the construction costs as compared to meeting the requirements of the current rule. There may be a savings in operating costs due to the proposed exemptions. The Department is unable to estimate this benefit due to the wide range of possible possibilities involved (size, features, types of disinfectant,plumbing, etc.).
