§ 15.65.030. On-site wastewater disposal permits.

A.

Required. A person may not install or modify an on-site wastewater disposal system, earth privy or vault privy without a permit from the department, except for simple repairs such as piping or moving parts repairs. A separate permit is required for each installation or modification.

B.

Submittal of application. All permit applications must be prepared by and bear the original signature of the applicant or an authorized representative. Such applications must be submitted to the department on forms provided by the department.

C.

Contents of application for repair or replacement of tanks. An application for a permit for repair or replacement of tanks such as septic tanks, holding tanks or lift stations must include:

1.

The legal description of the property on which the system is located;

2.

A description of the proposed repairs; and

3.

For proposed repairs involving replacement of the tank, distances from the old tank to all features listed in section 15.65.050.A that are within 200 feet of the on-site wastewater disposal system.

D.

Contents of application for installation or modification of subsurface disposal field. An application for a permit for repairs or modification of an existing on-site wastewater system that would involve expansion or construction of a subsurface disposal field, or an application for a permit for a new system, must include:

1.

A site plan, bearing the original signature and stamp of an engineer, drawn to standard engineering scale but not smaller than one to 100. The site plan shall show:

a.

The location of the on-site well and all components of the on-site wastewater disposal system, including but not limited to all piping and manholes, septic tank or holding tank, lift station, cleanouts, standpipes, the subsurface disposal fields, including all attendant piping, and the replacement subsurface disposal field;

b.

Measured dimensions of the on-site wastewater disposal field and distribution piping;

c.

Measured distances to all wastewater disposal systems, wells, surface water or drainage courses, roads, property lines and structures within 200 feet of the location of any existing or proposed on-site wastewater disposal systems;

d.

The locations of all soils, percolation or water table tests; and

e.

A description of the topography, areas of excessive slope, and extent of slopes and surface drainage patterns within 100 feet of any part of the system or portion of the lot intended for use for on-site wastewater disposal;

2.

A design of the on-site wastewater disposal system bearing the original signature and stamp of an engineer;

3.

The results of soils, percolation and water table tests conducted in accordance with this chapter. For new systems, these tests must be conducted and reported for both the original and replacement subsurface disposal fields; and

4.

A narrative description of probable impacts to adjacent properties. The comments must include but are not limited to consideration of:

a.

Wells;

b.

Wastewater systems;

c.

Reserved space or surface, and subsurface; and

d.

Drainage.

E.

Records. The department shall maintain indexed records of all engineering data submitted for permits and inspection reports and make this data available to the public. These data will provide historical information to aid in the design and approval of future systems.

F.

Issuance. The department shall determine, after review of the application and test results as well as available historic data, whether the proposed system complies with this chapter. The permit may be denied if provisions of this chapter or of accepted engineering and construction practices are not met.

G.

Authority to grant exceptions to requirements. The department may approve an on-site wastewater disposal system that does not conform to this chapter if the department finds, after consideration of relevant test results, engineering data, publications and other materials, that the system will function as effectively as a system that conforms to this chapter. The applicant shall be responsible for furnishing proof that the system will function as effectively as a system provided for in this chapter.

H.

Inspections; authority to require additional information. The department may conduct site inspections or require submission of additional information prior to the issuance of permits or health authority certificates. Information may include but is not limited to soil and percolation test results and topographic maps.

I.

Nonliability of department. Issuance of a permit does not constitute assumption by the department or its employees of liability for the failure of any on-site wastewater disposal system.

J.

Expiration of permit. A permit for an on-site watewater disposal system shall expire one year from the date of issuance, but may be renewed for one additional year at no additional fee.
