The Design Approval Permit shall be valid for a period of three years. No extensions shall be granted.

4.07.230  Notice to Agencies of Design Approval - New Construction
Other governmental agencies require District approval of a proposed wastewater system to serve proposed new construction prior to considering a permit application for development of a property. In recognition of this prerequisite, the Design Approval Permit may be sent by the District Engineer with the approval of the General Manager to other agencies when the proposed wastewater treatment system plans and specifications have been approved pursuant to Section 4.07.220. Said Design Approval Permit shall be conditioned upon final approval of the new construction project by the County of Marin and shall automatically be void should processing by the County of Marin of the application for the new construction project cease or the project submittals be denied by the County.

4.07.310  Revocation of Design Approval Permit
The General Manager may revoke in writing a design approval permit whenever evidence exists that the permit or approval may have been issued in error or on the basis of incorrect information supplied in the application or in violation of this code or other law or regulation. Such revocation shall require either prior or subsequent notice to the applicant by the District and an opportunity for hearing before the District Board.

4.07.410  Retention of Plans
Four sets of approved plans and specifications shall be retained by the District to include three standard sets of approved drawings and one reduced (11" x 17") reproducible drawing submitted by the applicant or the applicant's Designer.

4.07.510  Licensed Contractor Required
All work done pursuant to a Design Approval Permit shall be done by, or under the supervision of, a person holding an appropriate license as a contractor pursuant to state law. The owner may be authorized to perform permitted maintenance or repair work of a minor nature which work will not endanger the public health, nor violate any laws, ordinances, or regulations.

4.07.610  Inspections
The General Manager is authorized to set fees for failure to provide access for periodic inspections. In addition to any inspections performed by the District Engineer, all work for which a Design Approval Permit is required shall be subject to inspection by the General Manager or deputy in order to determine if such work conforms to the approved application, plans and specifications. All such work shall remain accessible and exposed for inspection purposes until inspected and approved and it shall be the responsibility of the owner or authorized agent to assure that required inspections are obtained. Should such work not be accessible for inspection, neither the District nor its employees and officers shall be liable for the expense entailed in the removal or replacement of any material required to allow inspection. A survey of the parcel may be required to verify that the construction work is located in accordance with approved plans. Approval as a result of an inspection shall not be construed to be an approval of a violation of the provisions of this code or other laws, ordinances or regulations.

4.07.620  Certification by Designer
Upon completion of work performed pursuant to the Design Approval Permit, and prior to issuance of a Discharge Permit, the designer shall certify that the work was performed pursuant to the District approved plans and specifications, as specified in Section 4.07.220, in the form specified below:

I [name of designer, professional title and state registration number] do hereby certify that based upon my inspections of the work performed on the wastewater treatment system pursuant to the repair/ construction permit issued on [date permit issued] conformed to the plans and specifications prepared by me as approved by the Stinson Beach County Water District.

This certification shall be dated and signed under penalty of perjury.

If the system was not installed as originally drawn, the designer shall submit as-built plans indicating all variations approved by the District Engineer and shall certify those plans in accordance with Section 4.07.620.

4.07.710  Discharge Permit
Upon completion and final inspection of work performed pursuant to a Design Approval Permit and receipt of certification by the designer, a Discharge Permit shall be issued and recorded with the Recorder of the County of Marin. Said Discharge Permit shall be conditioned upon the maintenance of, and the continued proper operation of, the wastewater treatment system as designed and constructed, upon payment of periodic permit fees and inspection fees, upon periodic inspections of said wastewater treatment system, and upon continuation of the use for which the system was designed. Every Discharge Permit shall indicate the design flows of the system.

4.07.720  Periodic Inspection
Every wastewater treatment system for which a Discharge Permit has been issued shall be inspected by the General Manager or deputy not less than every two (2) years. Depending upon the design and condition of the system, inspections may be more frequent. The frequency of inspection shall be specified on the current repair order.

4.07.725  Accessibility for Periodic Inspection
Upon notification from the District, owners are required to have all elements accessible for inspection, including access to the septic tank, sump tank, diversion valves, sand filter, leach field(s), alarms, panels, monitoring wells, and pumps. All riser lids shall weigh less than twenty-five pounds. All gates shall be unlocked and padlocks on panels or lids shall be removed prior to the inspector's arrival. All hatches must be easily removable. Deck hatches that weigh more than twenty-five pounds must be removed. If screwed down, all screws shall be removed prior to the inspection. Any obstructions, such as monuments and birdbaths that limit access must be removed. Pets must be confined during the inspection.

4.07.730  Purpose of Periodic Inspection
The purpose of a periodic inspection as provided in Section 4.07.720 shall be to determine the effectiveness of the wastewater treatment system in treating wastewater before it enters the groundwater. Factors to be evaluated relate to the design of the system, the nature and quantity of flow of wastewater entering the system, the condition and effectiveness of the components, the quality and condition of the soils into which wastewater is discharged, and the quality and nature of the groundwater receiving the discharge. Where found to be desirable, sampling wells may be required to be installed in and around the wastewater treatment system. Evaluation of the system shall be generally compared to the expected performance of the system as designed, compared to the expected performance of a new system installed in conformance to requirements for a replacement system, and related to the operation and maintenance requirements discussed in the Minimum Guidelines and the Design Manual.

4.07.732  Scope of Periodic Inspection
The scope of a periodic inspection shall include, but is not limited to:

  1. Verification of system component locations
  2. Diversion valve operation, pump runs, float operation and valve operation
  3. Verification of installation of mosquito abatement equipment including screening of all waste vents and proper sealing of all septic tank risers
  4. Measurement of scum and sludge depth
  5. Inspection for possible ponding, standing water, breakout and noticeable odors
  6. Examination of tank structure, pumps, and floats
  7. Performance of hydraulic loading to verify the timing of leach field hydraulic acceptance
  8. Monitoring of pump timers

All necessary procedures shall be performed in order to determine to the satisfaction of the inspector that the septic system is operating within health and safety parameters.

4.07.733  Notification of Completed Inspection
Upon completion of a periodic inspection, the District shall issue a Notification of Completed Inspection listing all required repair(s) and/or maintenance item(s), if any. The property owner(s) shall comply with all conditions within the required timeframe.

4.07.735  Change of Use
If an owner proposes a change of use for a wastewater treatment system, the General Manager or District Engineer may require the owner to demonstrate that the current system is adequate for the proposed use change and that the new use will not hasten deterioration of the system and will not degrade the surface or groundwater of the District. The General Manager or District Engineer may require the owner to submit a study/review of the system by an appropriately licensed designer so that the General Manager or District Designer can make an informed decision regarding the possible effects of the proposed change of use. The General Manager or District Engineer may require that the owner modify the system to provide an additional level of treatment to adequately treat the wastewater prior to disposal.

4.07.740  Revocation of Discharge Permit and Failed System Citation
When it has been determined that a wastewater treatment system for which a Discharge Permit has been issued is operating in violation of this code, operating in a manner not consistent with its design (such as frequently exceeding the design average or maximum daily flow rate), or is discharging wastewater in a manner which may result in the contamination of surface water, ground water, or the contiguous water bodies of the District, or contains components that do not conform to this code, or to which access for inspection has been denied, or which has not complied with specified repair order items, the Discharge Permit may be revoked upon written notice to the owner. If the owner, upon receipt of said notice revoking the Discharge Permit, does not appeal as provided in Section 4.05.060 or if upon appeal, the Board of Directors determines that the revocation shall be upheld, a failed system citation shall be issued to the owner and recorded with the County of Marin thirty days from the date of permit revocation.

4.07.745  Re-issue of Discharge Permit
Upon completion of system repairs and determination by District staff that the system is no longer in violation of this code, the Discharge Permit will be re-issued and recorded with the County of Marin. Discharge Permits shall also be re-issued in cases of ownership change.

4.07.760  Grading Permit Application
Marin County Grading Permit applications are subject to the review and approval by both County and District staff. The grading plans shall conform to Section 7006 (G) of the Uniform Building Code and shall indicate the approximate location of wastewater system 200 feet of the proposed grading improvements. When excavation is necessary for work to be performed pursuant to a New Construction or Maintenance Permit, a County Grading permit is not applicable.

The person reviewing an application on behalf of the District may request additional supporting data as needed. Such supporting data may include materials and studies as provided in Section 7006 (D) of the Uniform Building Code and as suggested in the Design Manual.

4.07.770  Other Permits
Aside from an individual sewage treatment system discharge permit, additional permit(s) will be required by the Marin County Building Inspection Department for electrical pump installations.
