Asbestos Cement Pipe
			 Maintenance and Repair Requirements
.
(a) Public and Private Utility Contractors or
			 other entities who have completed the "eighthour OSHA Class II Asbestos
			 Training: Asbestos Cement Pipe (ACP) Worker Safety" course found at
			 454
			 CMR 28.05 or a course similar in length and
			 content reviewed and approved in writing by the Department shall comply with
			 the following provisions and procedures.
1.
			 Complete a survey as required under
			 310
			 CMR 7.15(12A)(b).
2. Asbestos-cement pipe shall be handled in a
			 manner that will minimize the risk of making it friable ACM or releasing
			 asbestos dust into the environment, and with minimal disturbance.
3. Expose the asbestos cement pipe without
			 disturbing the pipe. Excavate no closer than six inches of the pipe. Carefully
			 uncover the remainder of the soil surrounding the pipe by hand or with a
			 shovel.
4. An assessment shall be
			 made by a person trained per
			 454
			 CMR 28.05(9)  to determine
			 if the pipe is damaged, cracked or broken.
a.
			 Not Damaged (intact and not deteriorated):
i.
			 Place six-mil thick polyethylene ("poly") sheeting under the asbestos cement
			 pipe to prevent soil contamination.
ii. Adequately wet the asbestos cement pipe
			 with amended water using surfactant or liquid soap before and during removal to
			 avoid creating airborne dust.
iii.
			 Separate the asbestos cement pipe at the nearest coupling (bell or compression
			 fitting).
iv. Slide the pipe apart
			 at the joints (no saw cutting) or use other methods that do not cause the pipe
			 to break, become friable or otherwise create the potential to release asbestos
			 fibers.
v. Wrap the wet asbestos
			 cement pipe and other debris in two layers of six-mil polyethylene sheeting,
			 seal with duct tape and label in accordance with all applicable regulatory
			 requirements. This can be done in the trench or adjacent to the
			 trench.
vi. If the trench is filled
			 with water, the placement of polyethylene sheeting is not required.
vii. Manage wrapped asbestos cement pipe,
			 polyethylene sheeting and any other material contaminated with visible asbestos
			 debris as asbestos-containing waste (ACW) in accordance with
			 310
			 CMR 7.15:
U Asbestos
and
			 310
			 CMR 19.061:
Special
			 Waste
b.
			 Damaged (deteriorated or not intact) or when cutting or mechanical breakage
			 (
e.g
., with saws, snap or blade cutting, and/or tapping) is
			 necessary:
i. Place six-mil thick polyethylene
			 sheeting under the asbestos cement pipe to prevent soil
			 contamination.
ii. Adequately wet
			 asbestos cement pipe with amended water where cutting or breaking will
			 occur.
iii. Saw cutting of asbestos
			 cement pipe shall only be conducted with a HEPA-shrouded vacuum attachment or
			 wet cutting equipment, unless it is conducted within a small enclosure that
			 isolates the area in which the saw cutting is being conducted to prevent the
			 release of asbestos fibers to ambient air.
iv. Wrap wet asbestos cement pipe in two
			 layers of six-mil polyethylene sheeting, seal with duct tape and label. Work
			 shall be done either in the trench or adjacent to the trench.
v. Manage wrapped asbestos cement pipe,
			 polyethylene sheeting and any other material contaminated with visible asbestos
			 debris as asbestos-containing waste (ACW) in accordance with
			 310
			 CMR 7.15:
U Asbestos
and
			 310
			 CMR 19.061:
Special
			 Waste
c. For
			 activities that disturb friable ACM, no visible emissions shall be discharged
			 to the outside air during the collection, processing, packaging or transporting
			 of any ACM or ACW.
5. The
			 final visual inspection shall be satisfied by complying with the following
			 requirements:
a. The visual inspection shall
			 be performed by a person trained per
			 454
			 CMR 28.05(9).
b. The person conducting the final visual
			 inspection shall:
c. Inspect the
			 work area to ensure there was no visible debris remaining:
i. In the excavation trench;
ii. In soil excavated from the
			 trench;
iii. In the surrounding
			 area adjacent to the trench after the removal of the asbestos cement pipe;
			 and
iv. On any tools used during
			 the removal/repair/replacement activities.
d. Ensure that all ACM has been removed for
			 proper storage/disposal.
e. Sign
			 and date the documentation of the final inspection as evidence that the
			 inspection was performed and that the condition of "no remaining visible
			 debris" was met. Owners/operators shall keep such documentation at their
			 regular place of business for two years from the date of final visual
			 inspection and provide it to the Department upon request.
