Current through Register Vol. XLI, No. 44, November 1, 2024
Section 64-16-15 - Administrative Due Process
15.1.

Closure Event

Corrective Action Required

A. Free Chlorine = less than 1.0 pm

Close the facility. Determine the cause. Make repairs or corrections.

B. pH of water = greater than 7.8

Close the facility. Determine the cause. Make repairs or corrections.

C. pH of water = less than 7.2

Close the facility. Determine the cause. Make repairs or corrections.

D. Inadequate lifeguards or

lifesaving equipment

Close the facility until the required number of lifeguards and lifesaving equipment are provided.

E. Accident Resulting In:

Lifeguard leaving station OR Body fluids discharged into water

Close facility until lifeguard returns to station.

Follow fecal accident cleanup procedures outlined below in item I if blood or feces are discharged into the water.

F. Water Clarity Unsatisfactory

(Main drain or 6 inch black disk in the deepest water on the bottom of a pool or spa not visible from the adjacent deck)

Close the affected area until the main drain or a six (6) inch black disk in the deepest water on the bottom of a pool or spa is visible from the adjacent deck.

Determine cause. Make repairs or corrections.

G. Free bromine = less than 2.0 ppm

Close the facility. Determine the cause. Make repairs or corrections.

H. Equipment Failure - Main pump, disinfectant feed equipment, or main drain covers.

Close the facility immediately upon main pump failure. Close the facility when disinfectant feed equipment fails and free chlorine falls below 1.0 ppm or free bromine falls below 2.0 ppm. Repair equipment. Test and balance chemical parameters prior to re-opening the recreational water facility. Close facility if main drain covers are missing, loose, or broken. Replace, secure, or repair as required.

I. Fecal Accident or Release of

Blood or Vomitus into Water *

Follow Cleanup Procedure A if:

A formed stool, visible blood, or vomit is discharged into the water.

Follow Cleanup Procedure B if:

A loose stool (e.g. diarrheal fecal accident) is discharged into the water.

Evacuate patrons from all water contaminated with fecal material. Do not let anyone back into the water until all decontamination procedures are completed.

Remove as much fecal material as possible using a net or scoop and dispose of in a sanitary manner. Clean and disinfect the net or scoop (e.g. after cleaning, leave the net or scoop immersed in the pool during disinfection). VACUUMING STOOL AND VOMITUS FROM THE WATER IS NOT RECOMMENDED.

_

Proceed to procedure A or B as required.

Cleanup Procedure A

1. Raise free chlorine to 2 ppm, adjust pH to between 7.2-7.5, and maintain for at least 25 minutes before letting anyone back into the water.

2. Ensure that the filtration system is operating during this entire process.

Cleanup Procedure B

1. Raise chlorine to one of the following concentrations, maintain for the corresponding time, and adjust pH to between 7.2-7.5:

a. 5ppm free chlorine for 32 hours;

b. 10 ppm free chlorine for 16 hours;

c. 15 ppm free chlorine for 12 hours;

d. 20 ppm free chlorine for 8 hours.

2. Ensure that the filtration system is operating during the entire process.

3. Backwash the filter thoroughly or clean the filter media after maintaining the required free chlorine concentration and time.

4. Adjust free chlorine concentration to less than 5 ppm before letting anyone back into water.

Cleanup Procedures A & B

Establish a fecal accident log. Document each fecal accident by recording date and time of event, note whether formed stool or diarrhea, and note the chlorine levels at the time or observation of the event. Before allowing anyone back into the water, record the pH , the procedures followed in response to the fecal accident (including the process used to increase chlorine levels if necessary), and the contact time.
