§ 13.20.080. Requirements for existing sewage disposal systems and upgrades to sewage disposal systems as part of new building construction.

A.

Nothing contained in this division shall be deemed a requirement to alter, change, reconstruct, remove or demolish any drainage system or part thereof if such system or work was installed in accordance with any applicable law in effect at that time. However, if any drainage system or other work regulated by this division is in the judgment of the administrative authority a nuisance, or is dangerous, unsafe, unsanitary or a menace to life, health or property, then such plumbing or drainage system or part thereof or work regulated by this division shall be made to comply with the requirements of this division.

B.

Applicants proposing new residential construction activities on existing structures that result in, or may result in, additional wastewater flows, including, but not limited to, the addition of a potential bedroom must comply with the requirements of this division. Remodels, additions, alterations or expansions of residences that increase and/or alter the square footage but do not result in additional wastewater flows are required to have the sewage disposal system inspected by a licensed sewage contractor for certification that the existing system is in good working order and an expansion area complying with the requirements of this division is established, if one does not already exist. An expansion area can only be established by the performance of a site evaluation complying with the requirements in this division and approved by the administrative authority. Minor construction projects that will not result in additional wastewater flows, or impact the primary or potential expansion sewage disposal system areas, may have the inspection and/or expansion area requirements waived at the discretion of the administrative authority.

C.

If it is impossible to maintain minimum distances between features on the same lot or parcel as required by Table 13.28.040, repairs may be made to systems where, in the opinion of the administrative authority, such repairs will not create a nuisance, or dangerous, unsafe or unsanitary conditions. In no event shall any repairs to a sewage disposal system, or part thereof, be allowed where the repaired system, or part thereof, is at a distance closer to a listed feature in Table 13.28.040 than currently exists on the same lot or parcel or adjoining lot or parcel. However, in no case shall the setback between wells and potential sources of sewage contamination be less than fifty feet.

D.

Where the administrative authority has determined that the existing drainage system or part thereof, or work regulated by this division is a nuisance, or is dangerous, unsafe, or unsanitary, then the administrative authority shall notify the owner thereof. The owner shall be required to bring such system into compliance with this division within thirty days (CPC Appendix Chapter 1, § 101.5, modified).
