(1) The pool or spa and related facilities shall be built in accordance with the plans as approved unless a modification of the approved plans is approved in writing by the department prior to construction or installation of the modification.
(2) Within 30 days of the completion and licensing of any pool, spa, or other water feature or related facilities, the professional engineer overseeing the project must submit a final certification to the department. The certification shall be submitted in the form of an "as-built" letter that identifies any changes that were made from the originally approved plans and it shall include scaled drawings that incorporate any changes that were made. The scaled plans and the "as built" letter shall be submitted to the department in hard copy and electronic copy. The electronic copy must be submitted in a format acceptable to the department. Any change from the approved plans must still meet all requirements of these rules.
