Current through Register Vol. 56, No. 24, December 18, 2024

Section 7:10A-1.14 - System classification

(a) Public wastewater treatment systems (S), public water treatment systems, or public noncommunity water treatment systems (T, VSWS), industrial wastewater treatment systems (N), public wastewater collection systems (C) and public water distribution systems (T, VSWS) shall be classified into one of the classes established in (b)1 through 5 below at Table I(S), Table I(T), Table I(N), Table I(C) and Table I(W), respectively.

1. Except for VSWS, the Department shall assign points to each public wastewater treatment system (S), public water treatment system or public non-community surface water treatment system (T), and industrial wastewater treatment system (N) for every item in (c) below that applies. The classification of each system as determined by (b)1 through 3 below shall be based upon the total number of points assigned to it in accordance with (c)1 through 3 below in Table II(S), Table II(T) or Table II(N), respectively.

2. The Department shall determine the population served or the population equivalent for public wastewater collection systems (C), and the population served or equivalent for public water distribution systems (W) as established at (b) 4 and 5 below in Table I(C), and Table I(W), respectively.

3. If unique treatment system conditions exist that are not set forth in the tables below, the Department shall adjust the system classification by determining the unique conditions equivalent to a comparable factor in the tables and assigning points accordingly.

4. The toxicity grouping for an industrial wastewater treatment system (N) in Table II (N) shall be determined from the North American Industrial Classification System (NAICS) code table, at (c)4 below, for the facility whose system is being classified.

(b) Systems are classified in accordance with the following tables:

NAICS (North American Industrial Classification System) codes are determined from the "Bridge Between NAICS and SIC (1997)" issued on June, 2000 by the US Census Bureau.

(d) A class 3 or class 4 treatment system will be classified as an automated system if:

1. The treatment system is designed and constructed in such a manner that in the event of system failure no untreated or partially treated water or wastewater is discharged;

2. An alarm system is provided which notifies a constantly staffed monitoring location that treatment system failure has occurred; and

3. Staff at the monitoring location are trained to properly respond to such an alarm.
