(E) The drawings for a lift station must show the location of the following:                      (i) all pumps, valves, pumping control equipment, safety equipment, and ventilation equipment;                       (ii) points that may be accessed by operational staff, such as manholes and cleanout ports;                       (iii) hatches and hoisting equipment for installing and removing equipment;                       (iv) slope and location of any wet well, floor grouting, valve vaults, valve vault pipes, and gas migration prevention measures used between a wet well and a valve vault;                       (v) pipe entrances and exits;                       (vi) sump pumps;                       (vii) elevations of level control switches; and                       (viii) any other lift station-related appurtenances.           
        (2) Construction drawings for a wastewater treatment facility.                  (A) The drawings for a wastewater treatment facility must show a vertical and horizontal scale and must include:                      (i) plan drawings of all pipes;                       (ii) plan and profile drawings of each treatment unit;                       (iii) the dimensions of each treatment unit;                       (iv) all mechanical, electrical, and construction details; and                       (v) a hydraulic profile of a wastewater treatment facility at both design and peak flows.                     (B) The construction drawings may include plans for future expansion of a wastewater treatment facility.                   (C) The construction drawings may include a clarification of any complex details of pipe systems by including an isometric flow diagram.         
        (3) The specifications for an alteration of an existing collection system or wastewater treatment facility must include technical descriptions of all equipment including:                  (A) the quantity and sizes of any equipment;                   (B) any applicable materials specifications;                   (C) testing requirements; and                   (D) citations to national standards with which the project complies.
