Cite as Conn. Agencies Regs. § 16-345-4
(a) Any excavator responsible for excavating or discharging explosives at or near the
location of public utility underground facilities or demolishing a structure containing
any public utility facilities shall:
(1) Except as provided in subdivisions (2) and (3) of this subsection, at least two full
days, excluding Saturdays, Sundays and holidays, but not more than thirty (30) days
before commencing such excavation, discharge of explosives or demolition at or near
the location of such public utilities facilities, notify the central clearinghouse
of:
(A) The specific location of the site of the proposed excavation, discharge of explosives
or demolition. Should field conditions or other circumstances require the excavation,
discharge of explosives or demolition to be expanded outside the originally designated
area established in accordance with subsection (c) of section 16-345-4 of the regulations
of Connecticut state agencies, a separate notification shall be made and said notification
shall be in accordance with the time requirements as provided in this subdivision;
(B) The name, address and telephone number of the entity giving the notice;
(C) The name, address and telephone number of the excavator actually performing the proposed
excavation, discharge of explosives or demolition and the name, address and telephone
number of the person, public agency or public utility for whom the activity is being
performed, except where the work is being performed by a public or municipal utility
for the benefit of a utility customer, the customer's name, address and telephone
number does not have to be provided;
(D) The date on which such proposed excavation, discharge of explosives or demolition
will occur. The date shall be at least two full days, excluding Saturdays, Sundays
and holidays, after the notice is provided to the central clearinghouse, or after
the area of proposed excavation, demolition or discharge of explosives is designated
in accordance with subsection (d) of this section whichever is later, but not more
than thirty (30) days after the notice has been provided to the central clearinghouse;
(E) The type of such proposed excavation, discharge of explosives or demolition;
(F) The method to be used to identify or designate the area of proposed excavation, discharge
of explosives or demolition and the date by which the designation will be made, where
the designation is not already shown on preconstruction plans;
(G) If it is an emergency, the basis for the emergency; and
(H) Such other information as the central clearinghouse or the Department shall deem necessary
to carry out the objectives of chapter 293 of the Connecticut General Statutes and
the public safety;
(2) In the event that an excavation or demolition without explosives is necessary to correct
an emergency involving danger to life, health, or property or the interruption of
operation of a major industrial plant, or to assure the continuity of public utility
service:
(A) immediately provide the notice required by subdivision (1) of this subsection to the
central clearinghouse if it is during hours when the central clearinghouse is open
for the purpose of determining the public utilities with facilities located at or
near the site of the demolition unless the public utilities whose facilities may be
affected are already known from a prior notification for excavation;
(B) immediately provide the notice required by subdivision (1) of this subsection directly
to the involved utilities; and
(C) notify the central clearinghouse by telephone of the emergency and response taken
as soon as reasonably possible if such notice was not given immediately prior to the
excavation or demolition;
(3) In the event that the use of explosives is necessary to correct an emergency involving
an immediate and substantial danger of death or serious personal injury, immediately:
(A) provide the notice required by subdivision (1) of this subsection to the central clearinghouse
if it is during hours when the central clearinghouse is open for the purpose of determining
the public utilities with facilities located at or near the site of the discharge
unless the affected public utilities are already known from a prior notification for
excavation;
(B) immediately provide the information required by subdivision (1) of this subsection
directly to the affected public utilities prior to discharge of the explosives; and
(C) provide notice directly to the central clearinghouse as soon as possible after the
discharge if such notice was not given immediately prior to the discharge;
(4) Use prudent judgment in determining whether to proceed with the excavation, discharge
of explosives or demolishing prior to the identification of any or all of the facilities
in the events covered by subdivisions (2) and (3) of this subsection. In exercising
such judgment, the excavator shall consider, among other things, the potential hazard
to life and property while awaiting public utility personnel to locate all the facilities,
the need for public utility personnel to locate the facilities having the greatest
potential for detriment to the public safety and the potential hazards that could
result from proceeding without having located the facilities and potential damage
to those facilities;
(5) Exercise reasonable care when working in proximity to the underground facilities of
any public utility. Reasonable care shall include, without limitation, the use of
construction methods appropriate to ensure the integrity of existing utility facilities
and their man-made temporary and permanent support including but not limited to adequate
and proper shoring and proper backfill methods and techniques; the selection of equipment
and explosives capable of performing the work with the minimum reasonable likelihood
of disturbance to underground facilities; adequate supervisory personnel to ensure
proper actions; proper understanding by the personnel on the job site of the authority
of all parties involved in the activity so that prompt action can be taken in the
event of unanticipated contact with underground facilities; adequate training of employees
in executing their assignments to ensure protection of utility facilities and the
public; maintaining necessary liaison with owners of underground facilities; sponsoring
preplanning and preconstruction meetings as necessary, and complying with all applicable
laws and regulations. If the excavator is utilizing trenchless excavation, the excavator
shall, if such excavation is expected to cross or encroach within the approximate
location of underground facilities either horizontally or vertically, prior to the
crossing or encroaching, determine the precise location of such underground facilities
expected to be so crossed or encroached;
(6) In the event that underground facilities of a public utility are likely to be exposed
by such excavating, discharging of explosives or demolishing, provide such support
or protection, or both, as may be necessary to protect such facilities from damage.
Where underground facilities containing combustible or hazardous fluids or gases (such
as natural gas, propane, jet fuel or chlorine) are likely to be exposed or where the
proposed excavation, discharge of explosives or demolition is to occur within the
approximate location of such facilities or affecting such facilities, except for excavations
performed in connection with the need to expose such underground facilities by the
owner of such facilities, an excavator may use mechanical equipment solely for the
purpose of removing the bituminous and concrete road surface. In such circumstances,
other than for the removal of a bituminous or concrete road surface, an excavator,
other than the owner exposing its own underground facilities, shall employ hand digging
only;
(7) In the event that the excavator, after reasonable attempt, is unable to precisely
locate the underground facilities after the approximate location of the underground
facilities have been marked, the excavator must notify the public utility requesting
such further assistance as may be needed to determine the precise location of the
underground facility; and
(8) Avoid the covering or removal of surface markings or stakes indicating underground
facilities during construction activity prior to actually excavating, discharging
explosives or demolishing in the vicinity of the located facilities.
(b) When any contact is done to any underground facility of a public utility, the excavator
responsible for the operations causing such contact shall immediately and directly
notify the public utility which owns or operates such facility of the contact, but
such person, public agency or public utility shall not tamper with or attempt to repair
such facility except to repair protective coatings when authorized by the owner of
the facility.
(c) An excavation notice given pursuant to subdivision (1) of subsection (a) of this section
shall expire at the end of thirty (30) days from the date such notice is given to
the clearinghouse. Whether or not an excavation, demolition or discharge of explosives
has commenced pursuant to a valid notification at any time within the prior thirty
(30) days, if such activity has not been completed or is expected to last beyond the
30 day period, a renewal notice must be provided before the expiration of the thirty
day period by the excavator. The renewal shall not be applicable for areas not designated
in the prior notification. If excavation, demolition or discharge of explosives was
not commenced pursuant to a valid notification at any time during the prior thirty
day period following the date which the notice was originally given, notice shall
be given again in accordance with subdivision (1) of subsection (a) of this section
by the excavator. Where any excavation, discharge or demolition activity has remained
dormant for a period of thirty (30) days from the date of the last notice given pursuant
to said subdivision, an additional notice shall be given before commencing such activity
by the excavator.
(d) The area of proposed excavation, discharge of explosives or demolition shall be designated
by the excavator in such a manner as to enable the public utility or owner of underground
facilities to know the approximate boundaries of the proposed excavation. The area
shall be designated as follows:
(1) if the area of proposed excavation is less than one thousand (1,000) feet longitudinally
along an existing highway, only surface marking in accordance with section 16-345-5
of the regulations of Connecticut state agencies may be used;
(2) if surface markings pursuant to section 16-345-5 of the regulations of Connecticut
state agencies are not used, designation must be by clear and appropriate markings
on a plan map which was originally prepared by a licensed surveyor or competent employee
of a public utility company or municipal utility and delivered to the public utility
whose underground facilities may be affected, if the area is 1000 feet or more longitudinally
on or adjacent to an existing highway and a preconstruction meeting is held by the
person or public agency performing the excavation, discharge or demolition activity
and all affected public utilities are notified of such meeting; and
(3) the designation of the area shall include the maximum depth of excavation at a sufficient
number of points to ensure an accurate profile unless detailed profile maps are provided.
The depth information provided shall reasonably reflect the anticipated actual depth.
(e) When any contact is made with any underground facility of a public utility, the excavator
responsible for the operations causing such contact shall:
(1) Immediately and directly notify the public utility which owns or operates such facility
of the contact, but such excavator shall not tamper with or attempt to repair such
facility except to repair protective coatings when authorized by the owner of the
facility. The excavator performing the excavation, discharge of explosives or demolition
shall use prudent judgment taking into account minimizing the potential detriment
to public safety in determining whether to cease activities pending the arrival of
qualified public utility personnel; and
(2) When such contact includes the occurring of a serious electrical short circuit or
the escaping of combustible or hazardous fluids or gases (such as natural gas, propane,
jet fuel or chlorine) or any other event endangering the public, the excavator responsible
for the excavation, demolition or discharge involved in such damage shall also alert
all persons within the danger area and take all feasible steps, including, where applicable,
notifying police, fire and other emergency personnel, eliminating sources of ignition
and evacuating employees and the general public from the affected area, but excluding
tampering with or attempting to repair the damaged facility, to insure the public
safety pending arrival of the appropriate public utility personnel.
(f) At all times when excavation, discharge of explosives or demolition are in progress
there shall be a representative of the excavator present in overall charge of the
operation who shall be knowledgeable regarding the operation being performed and the
legal name and address of the entity that is directly responsible for the performance
of the operation. This person shall have satisfactory evidence that the notification
requirements of these regulations have been met, such as the ticket number from the
central clearinghouse on site at all times.
(g) Each person, or public agency involved in excavation, discharge of explosives and
demolitions shall post a summary of the requirements of sections 16-345-1 to 16-345-9,
inclusive, of the regulations of Connecticut state agencies in construction workplaces.
Construction workplaces shall include, without limitation, offices of the entity performing
the work in a location where persons directly involved in excavation, discharge of
explosives and demolitions frequent, field offices and similar locations.
(h) The representative of the excavator shall provide the legal name and address of the
entity that is directly responsible for the performance of the excavation activity
and shall provide satisfactory evidence to any entity, including a public agency or
public utility requesting such information. Such representative shall also be an agent
for service of notice or process in any matter related to compliance with these regulations.
(i) Except as provided in subdivision (3) of subsection (a) of this section, explosives
may not be discharged unless such discharge was disclosed in the original notification
or upon six hours notice to all public utilities which have facilities at or near
the proposed discharge location, including those that were previously indicated to
have facilities at or near the proposed discharge but not in the immediate vicinity,
except that on Saturdays, Sundays and holidays, eight hours notice shall be provided.
