    (c) Provision of sufficient transition zones for deceleration preventing unsafe user impact; and
    (d) Maintenance of critical water operation levels providing proper braking action of the user.
    (6) Owners shall ensure design and construction of wave pools meet the following minimum standards:
    (a) Walls of wave pools shall be vertical with minimum six inch radius of curvature between wall and pool bottom;
    (b) Pool bottom sloped:
    (i) Not exceeding one foot of drop in twelve feet of run where pool depths range from zero to three and one-half feet; or
    (ii) Not exceeding one foot of drop in nine feet of run where depths range from three and one-half feet to six and one-half feet.
    (c) Recessed ladders or step holes with vertical grab bars at depths above three and one-half feet:
    (i) For emergency exit only;
    (ii) Spaced at intervals of fifty feet or less where pool water depths are greater than three and one-half feet. Pool water depths are measured without wave action.
    (d) Deck width of at least ten feet along the shallow end;
    (e) A fence or restrictive barrier a minimum of forty-two inches in height and at least two feet out from the pool/deck interface at the side walls of wave pools, with emergency exit openings.
    (f) Lifeguard station locations appropriate to prevailing conditions;
    (g) A push-button system to shut off the wave-making equipment with:
    (i) Shut offs installed on sidewall decks and spaced at intervals no greater than one hundred feet, readily accessible to the lifeguards; and
    (ii) Shock hazard protection.
    (h) A communication system for use by authorized personnel which is clearly audible to all portions of the pool;
    (i) A communication system for interaction between authorized personnel; and
    (j) Maximum bathing load (users) not to exceed a value equal to S/12+ D/68 where:
    (i) "S" equals surface area in square feet where depth is less than three and one-half feet;
    (ii) "D" equals surface area in square feet where pool depth is three and one-half feet deep or greater; and
    (iii) Pool depths are measured without wave action.
    (7) If inner tubes, boogie boards, or surf boards are used, the owner shall ensure the design and operation of the wave pool provides for such activity, including:
    (a) The establishment of rules for use;
    (b) Operating and emergency procedures; and
    (c) Crowd control.
    (8) Owners shall ensure design and construction of any wading activity pool meets the following minimum standards. Wading activity pool areas are:
    (a) Built with maximum water depth of two feet;
    (b) Constructed with pool walls so that distance from deck to water level is six inches or less for at least seventy-five percent of the pool perimeter;
    (c) Equipped with floors uniformly sloped to drain with a maximum slope of one foot of drop in twelve feet of run;
    (d) Separated by at least a four foot high barrier when distance to any water area greater than four feet in depth is less than ten feet; and
    (e) Protected from water areas greater than two feet by providing:
    (i) A float line separating the two areas;
    (ii) A six inch contrasting color line on pool bottom and side walls at float line; and
    (iii) A transition zone with a maximum floor slope not exceeding one foot of drop in twelve feet of run.
