001 The owner of a septic tank will have a Master or Journeyman Pumper, a professional engineer, or a registered environmental health specialist periodically inspect the septic tank and remove septage from the tank whenever the top of the sludge layer is less than 12 inches below the bottom of the outlet baffle or whenever the bottom of the scum layer is less than three inches above the bottom of the outlet baffle.
002 Pumping and disposal of domestic septage will be in accordance with this Title.
003 The owner of a lagoon will operate and maintain the lagoon in the following manner:
003.01 The liquid level in a lagoon will be maintained at a minimum depth of two feet. Additional water will be added as necessary to maintain the two foot minimum depth.
003.02 The lagoon area will be mowed to keep grass and other plants at six inches or less in height on the lagoon slopes and top of dike.
003.03 The lagoon will be operated to prevent the liquid level from encroaching on the one foot freeboard requirement of the lagoon.
003.04 Solids will be removed from the lagoon if needed through the services of a Master or Journeyman Pumper, a professional engineer, or a registered environmental health specialist and disposed of in accordance with this Title.
004 All dike surface areas from the design high operating waterline to the outside toe of the dike and all other areas which were disturbed during construction will be seeded or sodded, and a grass cover maintained to prevent soil erosion. Short grasses, such as blue grass are preferred and will be mowed frequently to prevent overhanging vegetation. Alfalfa and long rooted grasses which might damage the integrity of the lagoon will not be used. Weeds, cattails, reeds, and other wetland plants will be removed by physical or chemical treatment as they emerge. Trees will not be allowed to grow within a horizontal distance of at least 50 feet as measured from the high water mark for the maximum operating depth of the lagoon, but not less than 10 feet horizontal distance from the outer dike toe of the lagoon.
005 The integrity of fencing around lagoons will be maintained. The lagoon will be fenced with a four foot high woven wire, welded wire, or seven strand barbed wire with the first strand starting three inches from the ground and the following strands spaced evenly. The fence will be equipped with a standard main gate that is kept locked. The fence will be placed on the outside edge of the top of the dike or four feet outside the toe of the dike. A sign no less than 12 inches by 24 inches bearing the clearly-readable words "NO TRESPASSING - WASTEWATER LAGOON" will be located on the gate.
