Notice of Proposed Rule
DAR File No.: 33873
Filed: 07/29/2010 04:01:08 PM
Purpose of the rule or reason for the change:
The rule has been updated to address recent industry trends, reorganize the rule so it is easier to use, and respond to enforcement issues brought to the attention of the Utah Department of Health (UDOH).
Summary of the rule or change:
The proposed rule simplifies bather load requirements. Adds gravity drains and unblockable drains as alternatives for anti-entrapment systems allowed in new pools. Adds requirements for interactive water features. Broadens allowance of pool construction methods to include some new methods. Excludes private instructional pools from regulation as public pools. Brings wastewater discharge requirements in line with the current plumbing code adopted in Utah (changes air break to air gap discharge). Provides an allowance for wading areas to be integrated into swimming pools. Makes an exception of floor slope requirements for pools used exclusively for scuba diver training. Reorganizes requirements for special purpose pool so all the requirements for each type of pool are in one place. Makes allowances for underwater ledges, underwater seats, and underwater benches under certain circumstances. Allows handrails within a pool on stairs leading from a wading area to a swimming area. Allows some deck obstructions that are common in pools. Sets requirements for latch height for entrances into pools that protect young children but allow access for wheelchair users. Allows for designs that incorporate different turnover times for different zones within a single pool. Changes requirement for the water level from a set maximum below the deck to a requirement relative to the overflow structure. Makes an allowance for the use of energy-saving variable flow pumps. Makes changes to lifeguard requirements that are more in line with effective life guarding standard practices. Makes changes to lighting requirements that allow for energy efficient lighting. Relaxes the standard for pool water total dissolved solids to allow the use of electrolytic chlorinators. Allows the local health department to determine the maximum number of pools an operator may supervise to provide adequate oversight of the pools based on certain circumstances. Makes many nonsubstantive clarifications and corrections.

Anticipated cost or savings to:
the state budget:
There would be no additional costs to the state budget to enforce the proposed changes to this rule.
The majority of the proposed changes are either cost neutral or are a potential cost savings to local governments who operate pools. The costs savings cannot be accurately estimated as it is unknown how many operators would choose to build the newly allowed features. Costs that would be additional include the requirement that local health departments inspect interactive water features, if built, or are already built in their jurisdictions. The costs would be largely offset by permit fees charged.
The majority of the proposed changes are either cost neutral or are a potential cost savings. Those that can be addressed are listed as follows. The change in allowed bather load may, under certain circumstances, reduce revenue in some pools. The circumstances that would increase the likelihood of revenue loss due to the change are pools with little or no diving area and a very large non-swimming area compared to the swimming area. These pools could have a reduced allowed bather load. The revenue loss would occur if pool operators turned swimmers away from the facility because there were too many people already there. It is thought that this would be a rare occurrence for two reasons: 1) the majority of pools don't normally come close to reaching the maximum bather load allowed under the proposed rule; and 2) when there is a swimmer every four or five feet over the entire surface of the pool, swimming becomes much less attractive and thus tends to be self-limiting. Under the proposed rule, operators are allowed to not count the number of patrons in the facility who aren't actually using the pool in determining bather load. There are no records available of the allowed and actual bather loads over any period of time for all pools in the state, so determining an accurate assessment of the cost of the change can't be determined. The revenue loss of each patron turned away, if it occurs, would be about $5. Since existing interactive water facilities are not regulated in all jurisdictions (some local health departments have their own regulations for interactive water features), complying with the water quality (bacteria, chlorine, and pH) requirements of the proposed rule may have additional costs for existing facilities. Existing facilities would not have to meet new construction standards unless there is some safety problem with their present design. UDOH does not know of any facility owner who would have to modify their current design. For new interactive water features, since there were not state rules for them in the past, feature owners had few constraints in their design and construction. Features built under the proposed rule might thus be more expensive, yet more safe, to build than without the proposed rule. The number of facilities that might be built in the future or the aggregate cost to them from the proposed rule change cannot be estimated. Latch height at pool doors and gates has been a controversial issue in the past because building officials and health officials disagreed on the standard. Building officials wanted the latch to be at 48 inches to accommodate people in wheel chairs. Health officials wanted the latch to be at 54 inches to keep small children from entering the pool without supervision. The latch height requirement in the proposed rule in is line with the International Building Code which is adopted in Utah under the Utah Uniform Building Standards Act Rule. These requirements settle the controversy. If a pool has a latch at a height that doesn't meet the rule (maybe due to the controversy), there would be a cost to change the latch height. There are no records available to determine an estimate of the aggregate cost of this rule change.
persons other than small businesses, businesses, or local governmental entities:
Costs for other businesses are expected to be the same as for small business above.
Compliance costs for affected persons:
The majority of the proposed changes are either cost neutral or are a potential cost savings. Individual costs or savings cannot be estimated as it is unknown how many operators would choose to take advantage of the newly allowed features. However, if they do choose, then the saving/additional costs are made by choice, not requirement.
Comments by the department head on the fiscal impact the rule may have on businesses:
Overall the fiscal impact is expected to be positive with the allowance of less costly alternatives to achieve compliance.

(i) achieve cryptosporidium removal or inactivation to a level at least equivalent to the requirements in R392-302-34(4)(a);
(ii) assure safety for swimmers and pool operators; and
(iii) comply with all other applicable rules and federal regulations.
