<br /> PIT this system and is required. Monitoring & maintenance guidelines were u ` O
<br /> prepared for this system and were submitted with these plans to the Z
<br /> original owner; these guidelines must be understood and implemented for
<br /> the system to function reliably. All subsequent owners must secure a `
<br /> 0/5P05AL6 TiejNC-� 5ffCT/CN5 copy of, understand, and implement the monitoring and maintenance
<br /> guidelines or this design will be considered invalid,
<br /> - - - --- -- _ _ -- -- - - 3. This system is designed to accommodate ❑ finite quantity of domestic
<br /> 48'— NOT TO 5CALf wastewater generated by a single-family dwelling. felon-residential
<br /> wastewater will not be treated properly by this system and will damage its
<br /> components. Wastewater generation exceeding the daily design flow rate \J
<br /> listed elsewhere on these plans is likely to damage the system or cause
<br /> failure and is strictly prohibited. n
<br /> 4. All toilets and shower heads connected to this system must meet the \v}
<br /> following specifications: toilets shall have a maximum flush rate of 1.6
<br /> gallons per flush; shower heads shall have a maximum flow rate of 2.5
<br /> gallons per minute.
<br /> 5. Garbage disposal units will increase the need for septic tank pumping, will
<br /> increase the treatment load on the system, and will likely reduce the
<br /> system's functional life. These units, therefore, are strongly discouraged. j
<br /> 6. Recreational vehicle holding tank chemicals can damage this system's
<br /> microbiology and must not be discharged into the system.
<br /> 7. The creation of cut banks below the disposal or replacement areas
<br /> increases the possibility of interception and surfacing of migrating effluent I
<br /> and should always be avoided. Cut banks below the disposal or
<br /> replacement areas are created solely at the risk of the owner.
<br /> 8. The disturbance of native soils within or below the disposal or I
<br /> replacement areas increases the possibility of soil structure damage and
<br /> may lead to disposal field failure. Disturbance of native soils within or
<br /> below the disposal or replacement areas by any means including p !
<br /> vehicular traffic, grading, livestock, etc. is prohibited and will invalidate O ❑

<br /> INSTALLER'S RESPONSIBILITIES

<br /> 1, Construction of this septic may be undertaken only after obtaining a co
<br /> permit from the regulatory cuthority(ies). Do not begin construction O Q Q cl� Q�
<br /> prior to approval of this design and issuance of a permit by the
<br /> regulatcry outhority(ies). The owner and/or installer of this system
<br /> is/are solely responsible for identifying and obtaining any other
<br /> permits whiclh may be required for construction of this system.
<br /> 2. Inspections during construction by the designer and, in some cases,
<br /> the regulatory authority, are required. The installer and/or owner
<br /> are solely responsible for contacting the designer and/or regulatory
<br /> authority at least 24 hours in advance of each required inspection.
<br /> Every effort will be made to respond within 24 hours, however ❑
<br /> additional notice may sometimes be required. O N
<br /> 3. The permit and an approved set of design documents must be on
<br /> ct-
<br /> the job site at all times. V N
<br /> 4. The installer and/or owner are solely responsible for ensuring that Lr)
<br /> all property boundaries are accurately marked, that all appropriate
<br /> setbacks are observed, and that underground and/or overhead O Z U
<br /> utilities and/or utility easements are identified prior to construction, Q
<br /> These design documents may not show all present utilities. Q
<br /> 5, Under no circumstances shall the disposal or replacement areas, or W W p
<br /> the relative positions of the other system components, be modified __J Cy
<br /> without the prior consent of the designer and the regulatory Q
<br /> authority(ies). -0 p
<br /> 6. If the soil in the disposal area can be formed into a ribbon it is too 6 � �
<br /> wet to excavate. Do not remove vegetation, operate equipment, or
<br /> otherwise manipulate soils in the disposal area until receiving
<br /> approval from the designer.
<br /> 7. Disturbance of native sails in the disposal and/or replacement areas
<br /> and for a distance of 50 feet below the disposal or replacement ap
<br /> areas may damage the permeability of the soil column and cause z BEY d,�
<br /> premature system failure. Do not allow vehicular traffic, construction � �y`� d

<br /> equipment, or livestock in the area within or below the disposal or
<br /> replacement areas. 's
<br /> 8. Do not direct concentrated surface water runoff onto adjacent U
<br /> properties. Z o
<br /> 9. The OSI Simplex control panel utilizes magnetic motor contactors that yLLJ
