Current through Register Vol. 56, No. 18, September 16, 2024
(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.

(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.
