With the new addition to the existing rockbed the new rockbed would be <br /> 15'x 55"or 750 square feet of rockbed.The top of the existing system must be removed.The loam under <br /> the proposed addition must be removed down to the course sand and replaced with clean course sand to the <br /> elevation of the bottom of the existing rockbed.Add the new rockbed addition as per the design and replace <br /> the soil cover. <br /> All neighboring wells are located greater than 100 feet from proposed treatment area. <br /> Eacisting tanks may be used upon approval of the local inspector. A new 1250 gallon lift starion must be <br /> installed.The old 1000 gallon lift station is to be turned into a sepric tank. <br /> A LUG. Variance maybe needed to install an other system. <br /> The homeowner will be responsible for periodic monitoring of the other septic system. The monitoring set <br /> by LUG. <br /> The mitigation plan for this property is pressurized mound system. <br /> A water meter will need to be installed in the house. <br /> A ptunping chamber will need to be instalfed to lift the ef�luent to the treatment area. The power supply and <br /> switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A <br /> warning device must be installed with light and sound devices;this is in case of a pump failure. Keep all <br /> heavy equipment off of the proposed treatment areas before and after construction. The area around both <br /> sites should be fenced offbefore construction. This design is not valid and the system will need to be <br /> relocated if failure to protect the areas proposed for on-site sewage treatment occurs. <br /> Nothing other than gray water,((aundry,showers,etc.)human water and toilet tissue would be disposed af <br /> into the septic tanks. <br /> Sinc elv . <br /> / <br /> i <br /> Joseph J.
