The purpose of this chapter is to establish minimum requirements for the protection of public health, welfare and safety in the design, construction, maintenance and use of sewage disposal systems. (Ord. 243 § 1, 1954.)

The provisions of this chapter shall be enforced by the department of health of the county. (Ord. 243 § 2, 1954.)

For the purpose of this chapter:
A. “Construct” also means new construction, repair, alteration or relocation of a sewage disposal system;
B. “Department” means the department of health of the county;
C. “Person” means any person, firm or corporation;
D. “Sewage disposal system” means any septic tank, cesspool, structure, vault or pit for the disposal or treatment of sewage, and any drainage or other type system for the disposal of the effluent from such sewage collection structure. (Ord. 243 § 3, 1954.)

No person shall construct any sewage disposal system in any area of Mono County without first having obtained a permit therefor from the department; provided however that if such sewage disposal system is to be constructed in connection with a new dwelling or other new construction, the permit therefor shall be obtained prior to the commencement of construction of such new dwelling. Applications for permits to construct any sewage disposal system shall be made in such manner and on such forms as the department directs and devises. (Ord. 243 § 4, 1954.)

Persons applying for permits under this chapter shall pay such fees as may be set by resolution of the board of supervisors, not to exceed the county’s costs of administering this chapter. (Ord. 99-10 § 10, 1999.)

Upon the filing of an application, the department shall investigate the proposed sewage disposal system and the conditions affecting it to determine whether the construction as proposed would constitute a menace to public health. The department must grant, conditionally grant or deny a permit within ten days after the application is filed. (Ord. 322 § 1, 1961: Ord. 309 § 1, 1961: Ord. 243 § 5, 1954.)

Any person whose application for a permit has been denied may within thirty days after the date of such denial appeal therefrom in writing to the board of supervisors of Mono County. Such appeal shall be heard by the board of supervisors at its next regular meeting unless the appeal was filed within five days of such meeting, in which event it shall be heard at the next regular meeting subsequent thereto, and the board shall affirm or overrule the denial of such permit. (Ord. 243 § 6, 1954.)

Upon the completion of a sewage disposal system by an applicant to whom a permit has been issued, he shall notify the department of such fact by transmitting to the department a notice of completion on a form supplied by the department. (Ord. 243 § 7, 1954.)

The department may make such investigations and inspections after completion as may be necessary to determine that the plans and specifications approved in the permit have been complied with, and if it finds that the plans and specifications have been complied with, it shall issue to the applicant a certificate of completion. (Ord. 243 § 8, 1954.)

No portion of any sewage disposal system shall be constructed or located within one hundred feet of any stream, lake, spring, well or any other source of supply or body of water that is used or may be used as a domestic water supply unless permitted by the department to do otherwise. (Ord. 243 § 9, 1954.)

Any sewage disposal system constructed in violation of this chapter constitutes a public nuisance. (Ord. 243 § 10, 1954.)
