Rule 17.35.102 - LOCATION

(1) Stationary pumping equipment should generally be located as close to the boat off-loading point as possible and where boats need to maneuver the least. All components of the vessel pumpout station should meet the setback distances required in ARM Title 17, chapter 36, subchapters 3 or 9, as applicable, except that compliance with the setback requirement between a holding tank and surface water is not included in this recommendation.

(2) Holding tanks should be located where they are readily accessible for inspection and maintenance. The bottom of the tank should not be deeper than 12 feet from the finished grade or access road for ease of pumping and maintenance.
