<br /> O 1. All septic systems, regardless of type, have finite life spans and as such
<br /> will not operate indefinitely. In accepting this plan, the owner understands o
<br /> O 4"0 PERF. 24" and accepts that repair and/or replacement of all or portions of this
<br /> s stem will like) be re uired at some time in the future.

<br /> PIT this system and is required. Monitoring & maintenance guidelines were
<br /> prepared for this system and were submitted with these plans to the
<br /> original owner; these guidelines must be understood and implemented for
<br /> the system to function reliably. All subsequent owners must secure a
<br /> 4915P0 Al- T� z ff1 C1-1 ,5�CT10 ,5 copy of, understand, and implement the monitoring and maintenance
<br /> �J �/✓ / , ` � V � / / V guidelines or this design will be considered invalid.
<br /> �48'- _..._.... ._._-._ __.._...._ 3. This system is designed to accommodate a finite quantity of domestic
<br /> NOT TO 5CALE wastewater generated by a single-family dwelling. Non-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. o
<br /> 4. Aii toilets and shower heads connected to this system must meet the
<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.
<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
<br /> and should always be avoided. Cut banks befow 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
<br /> replacement areas increases the possibility of soil structure damage and C13
<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
<br /> this design. �Ll

<br /> INSTALLER'S RESPONSIBILITIES W
<br /> w -•
<br /> 1. Construction of this septic may be undertaken only after obtaining a Q W iyj
<br /> permit from the regulatory authority(ies). Do not begin construction S ❑ ❑ ❑ rl� ct
<br /> prior to approval of this design and issuance of a permit by the
<br /> regulatory outhority(ies). The owner and/or installer of this system
<br /> is/are solely responsible for identifying and obta;ning any other
<br /> permits which may be required for construction of this system.
<br /> 2. Inspections during construction by the designer and, in some cases,
<br /> the regulatory outhorAy, 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 C)
<br /> additional notice may sometimes be required. Q N
<br /> 3. The permit and an approved set of design documents must be on
<br /> the job site at all times. U N
<br /> 4. The installer and/or owner are solely responsible for ensuring that
<br /> all property boundaries are accurately marked, that all appropriate U
<br /> setbacks are observed, and that underground and/or overhead O �Z U
<br /> utilities and/or utility easements are identified prior to construction. LZ 0
<br /> These design documents may not show all present utilities.
<br /> 5. Under no circumstances shall the disposal or replacement areas, or W W j p
<br /> the relative positions of the other system components, be modified d
<br /> without the prior consent of the designer and the regulatoryto
<br /> Q
<br /> authority(ies). W ti Ca
<br /> 6. If the soil in the disposal area can be formed into a ribbon it is too <t
<br /> wet to excavate. Do not remove vegetation, operate equipment, or C', Lo
<br /> otherwise manipulate soils in the disposal area until receiving
<br /> approval from the designer.
<br /> 7. Disturbance of native soils 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
<br /> premature system failure. Do not allow vehicular traffic, construction
<br /> equipment, or livestock in the area within or below the disposal or
<br /> replacement areas. `
<br /> 8. Do not direct concentrated surface water runoff onto adjacent ¢ 1
<br /> properties. W _Z ;3o
<br /> 9. The OSI Simplex control panel utilizes magnetic motor contactors that Z w
<br /> can cause noise and/or vibration in the dwellirg if mounted on the Od ti� Al
<br /> dwelling's exterior wall. Coordinate panel location with the owner �����( Lu 5�
<br /> prior to mounting to avoid conflicts. o�R �
