(1) Location. Owners shall ensure pump houses, planters, balconies, landscape features, trees, and structures are located fifteen feet or more horizontally away from any swimming pool, or provide barriers or other means to prevent diving or ready access to a pool from the structures. These structures do not include:
(a) Building walkways above the second story;
(b) Inaccessible roofs eight feet or more in height; or
(c) Any barriers provided to prevent unauthorized pool access (e.g., fencing).
(2) Walking deck surfaces. Owners shall design and maintain walking deck surfaces as follows:
(a) For pools less than fifteen hundred square feet, walking deck surfaces must be at least four feet wide around the entire perimeter of pools;
(b) For pools less than fifteen hundred square feet, walking deck surfaces must be at least:
(i) Six feet wide at the shallow end of a variable-depth pool; and
(ii) Six feet wide on a minimum of twenty-five percent of the deck space of free form pools.
(c) For pools fifteen hundred square feet or larger, walking deck surfaces must be at least six feet wide:
(i) Around the entire perimeter of outdoor pools;
(ii) On fifty percent of the perimeter of indoor pools; and
(iii) The remaining fifty percent perimeter of the indoor pool must be a minimum of four feet wide.
(d) For pools fifteen hundred square feet or more, walking deck surfaces must be at least sixteen square feet per bather. To determine maximum bather load see subsection (10) of this section. If the owner provides maximum facility occupancy loading less than that of subsection (10) of this section, and the occupancy limit is posted and enforced, that loading may be used in lieu of the maximum bather load figure as described under subsection (10) of this section; and
(e) General use pools may not have sand and grass areas within the pool enclosure unless these areas are separated to prevent direct access from the pool area and the facility provides a means for cleansing bather's feet before reentering the pool and deck area.
(3) Pool general floor and wall dimensional design.
(a) Owners shall ensure pool dimensional designs for floors and walls provide for safety, circulation and quality of water;
(b) Pool floors must have uniform slopes with:
(i) A maximum slope of a one-foot drop in twelve feet of run at pool depths to five or less in pools fifteen hundred square feet or more; and
(ii) Floor slopes not intruding into the area designated as the diving envelope.
(c) Pool sidewalls may not curve or intrude into the pool beyond the vertical more than twelve inches at three and one-half feet and eighteen inches at a depth of five feet. The radius of curvature of wall-floor junctions may not exceed the maximum radius designated in Table 041.1 of this section for depths over five feet. Vertical means walls not greater than eleven degrees from plumb:

For pool depths less than three feet and greater than five feet, values shall be extrapolated.
 
Radius of coving shall not intrude into pool within diving envelope.
(d) Pool configuration must have a transitional radius from wall to floor where floor slopes join walls so that:
(i) The center of the radius not less than the minimum vertical depth specified under Table 041.1 of this section below the water surface level;
(ii) The arc of the radius is tangent to the wall; and
(iii) The maximum radius of coving, or any intrusion into the pool wall/floor interface, is determined by subtracting the vertical wall depth from the total pool depth.
(4) Ledges. In new construction or alterations to existing construction, ledges are prohibited in swimming pool sidewalls, except as specified in WAC 246-260-091(3).
(5) Specific design requirements for pools furnishing areas for diving. Owners shall ensure areas designated for diving activities include a diving envelope meeting minimum requirements in:

(3) Other Terms and Conditions:
(a)
The department may charge an additional fee of $87 plus associated laboratory costs for any inspections beyond those provided under the annual operating permit when necessary due to violations of such items as (a) noncompliance with water quality standards, and (b) failure to comply with operational requirements for health and safety.
(b)
The department may charge an alternate annual fee for an operating permit based on direct and indirect costs associated with issuance of the permit when arrangements are made with local health jurisdictions to administer all or portions of the duties associated with the operating permit. Except, that the fee for this operating permit cannot exceed the cost established by the previous portions of this regulation, but the fee may be less.
(c)
During the first year of development of the operating permit and for new pool facilities built hereafter, or pools temporarily closed (significant period of several months) and reopened, there are provisions for prorating the costs for the operating permits.
(d)
A reduction in fees, up to but not exceeding thirty percent, may be granted by the department when a facility operator can demonstrate a satisfactory level of training in pool safety, water quality, maintenance and operations. The department will develop criteria for these fee reductions within six months of the adoption of this regulation.
(e)
For limited use facilities requiring operating permits which are serving less than fifteen living units, the operating permit shall be fifty percent of the fee. However, the department may charge a reinspection fee if necessary under (a) of other terms and conditions.
(f)
Fees for multiple facilities at the same physical location shall have a maximum FEE CAP as follows: Seasonal (0-6 months) WRF's: $774 NOTE: The third and subsequent pool/spa at the same location will be charged $51 for each additional pool/spa.
 
Year around (˃6 months) WRF's $1032 NOTE: The third and subsequent pool/spa at the same physical location will be charged $67 for each additional pool/spa.
(4) Examples of Fees Charged:
(a)
If more than one pool at a facility and one is a year-round pool and another is a seasonal pool—year-round pool is base cost, seasonal pool is charged at additional fee charge. For example: Year-round spa = $424 plus seasonal swimming pool is $63 = $487 total operating permits.
(b)
If a single swimming pool and a single spa pool is used at the facility, the fee schedule will include fees as noted. For a 0-6 month permit, the primary fee for the single swimming would be $291 and the spa pool would be viewed as the second pool at the facility and would have a fee of $63, total operating permit fees would be $354.
(c)
If there are 12 pools/spas at a single year-around pool facility, the FEE CAP would apply and the maximum fee of $1032 would be charged. ($477 base fee, $84 for first additional pool/spa, $67 for the remaining ten year-around pools/spas (10 x $67 = $670)) Total fee before fee cap = $477 + $84 + $670 = $1231. After FEE CAP the total fee = $1032. If approved training were credited to this facility for the maximum 30% discount, the 30% would be applied to the FEE CAP fee of $1032; $1032 - 30% = $723.
