(d) The authorized agent shall issue a written notice of non-compliance to the owner when the wastewater system is non-compliant with G.S. 130A, Article 11, the Rules of this Subchapter, or the performance standards or conditions in the OP or ATO.

(e) The Department shall review and approve the wastewater system, including design, layout, plans, and specifications for all wastewater systems that serve a facility with a cumulative DDF greater than 3,000 gpd, as determined in Section .0400 of this Subchapter. The Department shall also review and approve plans and specifications for the following:

(1) IPWW systems required by this Section to be designed by a PE unless the wastewater has been determined to not be IPWW in accordance with Rule .0303(a)(17) of this Section;

(2) advanced pretreatment or drip dispersal systems not previously approved by the Department; and

(3) any other system so specified by the authorized agent.

(f) Department review shall not be required when the cumulative DDF for the facility is greater than 3,000 gpd as determined in Section .0400 of this Subchapter and:

(1) the wastewater system is made up of an individual wastewater system that serves an individual dwelling unit or several individual wastewater systems, each serving an individual dwelling unit; or

(2) the wastewater system meets the following criteria:

(A) the individual wastewater system(s) serves individual design units with a DDF less than or equal to 1,500 gpd;

(B) the initial and repair dispersal fields for each individual wastewater system(s) is, at a minimum, 20 feet from any other individual wastewater system;

(C) the total DDF for all dispersal fields is less than or equal to 1,500 gpd per acre based on the portion of the land containing the dispersal fields; and

(D) the wastewater is not HSE as identified in Section .0400 of this Subchapter.

(g) Department review shall not be required when a PE calculates the proposed DDF to be less than or equal to 3,000 gpd based on engineering design utilizing low-flow fixtures and low-flow technologies in accordance with Rule .0403(e) of this Subchapter.
