  (a) If alcoholic beverages are consumed at the gathering, the operator shall increase the number of required toilets by 40%.

  (b) Five percent, with a minimum of one, of the required number of toilets shall be handicap accessible and shall be identified by the International Symbol of Accessibility in compliance with 36 CFR 1191 (July 1, 2011), Appendices B and D, of the Americans with Disabilities Act.

  (c) For an event lasting longer than ten hours, the number of required toilets is calculated by adding the number of toilets for ten hours to the number of toilets for those hours over ten or a portion thereof, as determined in Table 1.

  (d) The operator shall locate portable toilets a minimum of 100 feet from any food service operation and not more than 300 feet from grand stand or spectator or from other areas of activity which pertain to the gathering, as outlined in the permit application. Where site conditions limit the placement of portable toilets, the health officer may allow exemptions to these distances.

  (e) The operator shall provide working hand wash stations at a minimum rate of one per ten portable toilets or portion thereof. The operator shall provide soap, water and single use towels at each hand wash station. Where conditions make the use of soap and water impractical, the health officer may allow sanitizing gel in place of soap and water. Sanitizing gel may not be used in place of soap and water at hand wash stations used by food service workers.

  (f) The operator shall provide a minimum of one covered trash container for every ten portable toilets or portion thereof.

  (g) The operator shall ensure that all portable toilets are of sound construction (such as non-absorbent polyethylene), easily cleanable, and durable.

  (h) Each portable toilet must be secured against vandalism and adverse weather conditions by tie downs, anchors or similar effective means.

  (i) The operator shall contract with a liquid waste hauler that is permitted by the local health department in accordance with R317-550, Rules for Liquid Waste Operations.

  (l) The operator shall ensure that all wastewater is removed from each portable toilet at least once every 24 hours or more frequently as necessary. On a case by case basis, the health officer may change this frequency because of the time of year, weather conditions, nature of the event or other public health related criteria. All wastewater removed shall be disposed of at a wastewater treatment facility in accordance with State and local wastewater disposal laws.

  (m) The operator shall ensure that each portable toilet is serviced and sanitized as necessary to maintain sanitary conditions.

  (n) At the conclusion of the gathering, each portable restroom unit must be serviced then removed within 48 hours. The health officer may extend or shorten this time because of the time of year, weather conditions, the nature of the event or to meet other public health related criteria.
