This document is intended to fulfill the EGLE R 325.2194a contingency plan required by the state of Michigan.

== Formed Stool ==

EGLE considers this a "limited contamination" event. The guidelines below are per PHTA, ensuring compliance with to EGLE requirements.

# Immediately close the pool. Direct all occupants to leave the pool area.
# Remove the contaminant from the pool and discard in a sanitary matter. Vacuuming to remove the contaminant is not recommended.
# Clean and disinfect the net or scoop.
# Ensure the free available chlorine is at least 2 ppm (raise as needed), the pH is 7.5 or less and the temperature is 77 °F or higher.
# Maintain the chlorine concentration for the period defined by the table below before opening the pool.
# Ensure the filtration system is operational while the pool reaches and maintains proper free chlorine concentration.
# Document the incident on the monthly operation report or a separate log sheet (see [Documentation], below).
# The pool may be re-opened
