Operation. Each
Supplier of Water shall ensure that its Public Water System is operated at all
times by a Primary and Secondary Operator for the treatment and distribution of
drinking water, unless otherwise authorized in writing by the Department. Any
Public Water System personnel who make decisions regarding the Public Water
System's process control or operational integrity shall be certified pursuant
to 236 CMR:
Board of Certification of Operators of Drinking Water
Supply Facilities. Exemptions to this requirement are addressed in 310
CMR
22.11B(5). The Primary Operator shall be directly responsible for the
operation of a Treatment Facility and/or Distribution System. The Secondary
Operator shall be directly responsible for the operation of a Treatment
Facility and/or Distribution System or a major segment of the Public Water
System, during the temporary absence of the Primary Operator or during
operational shifts when the Primary Operator is not scheduled to work. Persons
exercising official general administrative duties such as city engineers
exercising engineering design duties, elected water commissioners, clerks or
administrative workers involved in customer relations, billing, payroll,
timekeeping,
etc. shall not be considered directly responsible
for a Public Water System, unless otherwise authorized in writing by the
Department.
(2)
Staffing Requirements. In order to ensure the proper
management, operation and maintenance of Public Water Systems, every Public
Water System, except as provided in 310 CMR

request for the Department to approve an alternative work schedule for the
Primary Operator. The proposed alternative work schedule shall demonstrate that
the Primary Operator will work at least 35 hours and at least four days each
work week (as defined in 310 CMR
22.11B(2)(a)1.) at the Distribution System to
ensure its safe and proper operation.
(d)
Distribution - Secondary

staff the higher grade Treatment Facility, but shall not be required to staff
each lower grade Treatment Facility.
(f) Staffing and Comprehensive Operations
Plan. A Supplier of Water, upon request from the Department, shall submit to
the Department for review a "Staffing and Comprehensive Operations Plan" on a
form provided by the Department and, if applicable, a Contract Operator
Compliance Notice, demonstrating compliance with 310 CMR
22.11B(2).
(3)
Primary and
Secondary Operator Changes. Except for periods of temporary
absence of no more than 30 days, whenever a Supplier of Water changes a
Certified Operator responsible for primary or secondary supervision under 310
CMR
22.11B(1),
(a) the Supplier of Water shall
report the change to the Department within seven days, thereafter;
(b) the Supplier of Water shall submit to the
Department for review an updated "Staffing and Comprehensive Operations Plan"
and, if applicable, a Contract Operator Compliance Notice, within 30 days of
the change described in 310 CMR
22.11B(3)(a); and

replacement Primary or Secondary Operator(s) of appropriate grade no later than
30 days from the date the current operator(s) ceases to perform the Primary or
Secondary Operator duties.
(4)
Classification of Public
Water Systems. A Public Water System's Distribution System shall
be classified in accordance with 310 CMR
22.11B(4)(c) and its Treatment
Facilities, if any, shall be classified in accordance with 310 CMR
22.11B(4)(a). However, if the Public Water System is a free standing vending
machine, it shall be classified instead in accordance with 310 CMR
22.11B(4)(b)
or (d), as applicable. The overall classification of each Public Water System
shall be indicated by the classification of its Distribution System followed by
the numerically highest class of its Treatment Facilities, if any
(
e.g., III-D/II-T) or its vending classification
(
e.g., II-VNDT). The increasing numerical class indicates an
increasing complexity of operation and a higher level of training, knowledge,
and experience required for operation. The certification grades for operators
established in 236 CMR
3.02:
Classification of Public Water System
Operators, shall correspond to the classification of the system as
required under 310 CMR
22.11B(4). The Department shall make the final
determination of all such classifications.
(a)
Rating Treatment Facilities. The class of each
Treatment Facility within a Public Water System shall be established by adding
together all rating values reflecting the complexity of operation for such
Treatment Facility's treatment units, as set forth in 310 CMR
22.11B:
Table 1. Treatment Unit Rating Values.

satisfaction that:
1. due to compelling
factors the Supplier of Water is unable to comply with the requirements of 310
CMR
22.11B(1) or (2);
2. the
granting of the requested exemption will not result in an unreasonable risk to
health or impair the quality of water which is being delivered to the Public
Water System's consumers;
3. the
Supplier of Water can ensure the proper operation of the Public Water System
and can detect any malfunctions in the operation of the Treatment Facility or
Distribution System in the absence of the Primary Operator;
4. the Primary Operator is able to respond to
Emergencies within a reasonable period of time. In no event shall an Emergency
response time greater than one hour be deemed reasonable;
5. the Primary Operator is responsible for
the operation of the Public Water System at all times whether or not present in
person; and
6. any individual
utilized by the Supplier of Water to operate the Public Water System and to
detect any malfunctions in the operation of the Public Water System in the
absence of the Primary Operator, is properly trained by, and is acting under
the direction of, the Primary Operator.

classified as a I-D or less may reduce the staffing requirements of 310 CMR
22.11B(1) and (2) by operating the Distribution System on a part-time basis.
With the prior written approval of the Department, a Supplier of Water whose
Public Water System includes a Treatment Facility classified as I-T or less may
reduce the staffing requirements of 310 CMR
22.11B(1) and (2) by operating the
Treatment Facility on a part-time basis. A Supplier of Water seeking a
reduction in the staffing requirements shall be subject to the conditions
listed at 310 CMR
22.11B(5)(a)1. through 6. and (b). Subject to such
approval(s), the Primary and Secondary Operators or both may be allowed to
operate the Treatment Facility or Distribution System on a part-time
basis.
(d)
Public Water
System - Automated Operations. Increased instrumentation,
automation and SCADA Systems may be used to reduce the number of on-site staff
required during periods of routine operation. A Public Water System which has
been designed for off-site monitoring may apply to the Department for an
exemption from the requirements of 310 CMR
22.11B(1) and (2).
1. The Department shall use, but not be

tanks and clearwells;
c. the
estimated length of time for water quality to deteriorate from a treatment
process failure such that unsafe or impure levels of drinking water are present
in the Distribution System;

variability of source water quality;
e. the degree of sophistication, reliability
and control of the instrumentation monitoring and control system;
f. the location of the off-site monitoring
site with respect to operator response and/or travel time to the Treatment
Facility;
g. the adequacy of the
Emergency response plan when alarms or out-of-range parameters are reported by
Distribution System or Treatment Facility instrumentation;

process malfunction;
j. the
ability of improperly treated water to be flushed from the Distribution System
prior to the first customer without an interruption of water service;
k. demonstration that the Public
Water System has adequate capacity to repair and maintain the automated
controls or show that it has an agreement with a third party to do so; and
l. secured remote
access.
