To receive an inspector certificate of competency you must meet the requirements below:

(1) Be an employee of a local health jurisdiction that reviews, inspects, or approves the design and construction of on-site wastewater treatment systems.

(2) Have one year of practical work experience under the supervision of a certificate of competency holder or one year of previous work under a licensed on-site designer or professional engineer, unless otherwise approved by the board.

The board will consider the following in evaluating the practical work experience: Verification(s) provided by the applicant, the demonstration of the ability to work within the regulatory structure and familiarity with the aspects of on-site wastewater system design, construction, and maintenance.

The work experience must demonstrate understanding of chapter 246-272A WAC and associated department of health recommended standards and guidance (RS&G) documents. In addition, the work experience should include:

(a) Review of site characteristics such as soil types and location of water tables.

(b) Review of well siting, testing, and construction.

(c) Review of plats and land subdivisions.

(d) Review of septic system designs.

(e) Review of system installation and construction.

(f) Review of system troubleshooting and operations and maintenance.

The applicant must demonstrate their knowledge and experience in more than one area listed under (a) through (f) of this subsection.

(3) Fully complete the application form to the satisfaction of the board.

(4) Provide a written request from the local health jurisdiction. Requests shall be submitted on a form prescribed by the board.

(5) Pay all applicable fees.

(6) Obtain a passing score on the Washington law review.

(7) Obtain a passing score on the on-site designer examination.

Upon passing the on-site designer examination, the applicant will be issued a certificate of competency. Issuance of the certificate of competency does not authorize the certificate of competency holder to offer or provide on-site wastewater treatment system design services to the public. However, nothing in this chapter limits or affects the ability of local health jurisdictions to perform on-site design services under their authority in chapter 70.05 RCW, RCW 18.210.190 (3)(d) and WAC 246-272A-0230.
